Description
FIELD OF THE INVENTION
[0001] The present invention is directed towards portable
containers designed to for use in a medical pad warming unit;
particularly towards an insulated, hand-held containers able to
readily dispense individual medical pads, and most particularly
toward portable containers which includes a heating means that is
able to maintain the individual medical pads at the desired
temperature without needing to return the container to the medical
pad warming unit.
BACKGROUND OF THE INVENTION
[0002] More than 90% of patients that are admitted to clinical care
facilities have a venipuncture procedure performed. Perhaps the
most frequently encountered problem associated with introducing a
needle into the vein of a patient is the inability to consistently
access the vein on the first attempt. This common problem is due to
the wide variety of factors including; phlebotomist's experience
and skill, location of the access site, the caliber and condition
of the target vein, vasoconstriction related to shock, fear or low
temperature.
[0003] Prior to performing venipuncture, the phlebotomist typically
sterilizes the patient's skin using commercially available
disposable anti-microbial medical pads or gauze. Typically these
medical pads means are packaged for single use within a fluid
impermeable package containing a pad pretreated with at least 70%
isopropyl alcohol or betadine. These individual packages are
frequently used in hospitals, physician's offices, ambulances,
nursing homes, health departments, laboratories and other clinical
facilities. Often these medical pads are stored together in a
portable container constructed for easy transport to the patient's
bedside or within a vehicle (i.e., ambulance).
[0004] Additionally, these individual packages are often stored at
room temperature prior to use. As soon as the alcohol is applied to
the pad, it begins to evaporate and cool the pad. The pad becomes
cool to the touch and its initial cooling is enhanced by the
continued evaporation of the alcohol on the skin. The application
of the pad is often uncomfortable for the patient and it tends to
make the veins constrict under the skin, known in the art as
vasoconstriction, thereby making the drawing of blood sample more
difficult.
[0005] In addition, vasoconstriction has been linked to; increased
frustration and anxiety of both the patient and the clinician,
increased discomfort and potential for pain, an increased number of
intravenous attempts and increase in accidental needle-sticks and
additional time and equipment spent on multiple attempts.
[0006] Phlebotomists have long recognized the enhanced ease of
venous access in many patients by warming the intended puncture
site. Current methods include warming the intended access site with
a towel, alcohol pads, betadine pads or compress which is first
warmed in a microwave oven, blanket, radiant warmer (i.e., heat
lamp), chemical warm pack or hot water. However, the method of
warming medical pads via a microwave oven, heated water source, or
radiant warmer is potentially dangerous due largely to the
inability to precisely control the temperature range of the water
source or microwave oven, thus, increasing the risk of burning the
patient. In addition, most commercially available medical pads are
enclosed in foil-lined packages, presenting a fire and/or explosion
hazard when placed in a microwave. Blanket warmers are considered
ineffective as these large pieces of equipment are not readily
portable and hospital approved for use as a blanket only, as they
can produce electrical injury/shock or interference with other
medical equipment. The use of room temperature medical pads after
application of a chemical warm pack over the intended access site
can cause a vascoconstrictive effect and require additional
venipuncture attempts.
[0007] The medical warming pad apparatus disclosed in U.S. Pat. No.
6,316,750 to the present inventor (herein incorporated by reference
in its entirety) has effectively solved these aforementioned
problems utilizing a simple and elegant tabletop insulated case
designed to keep medical pads warm and in a condition ready for
application over a period of hours. The insulated case includes a
cover, multiple internal containers and a source of controlled heat
to warm the medical pads housed within the containers. A strategic
analysis done by Harvard University using the insulated case
disclosed in U.S. Pat. No. 6,316,750 discovered an impressive time
and cost savings of more than $35,000/year for a facility that
performs only 10 venipuncture procedures a day. Thus, a decrease in
the number of intravenous attempts is more economical due to higher
patient turnover, not to mention the benefits derived from
increased patient and clinician satisfaction.
DESCRIPTION OF THE PRIOR ART
[0008] A variety of methods and procedures have been described in
the prior art for disposable pad or towellets heating
apparatus.
[0009] For example, U.S. Pat. No. 3,867,939 to Moore et al.,
disclose a disposable pad for controlling body temperature at
selected areas for application. The pad includes a flexible fluid
conduit for passage of source fluids, whether hot or cold, and a
soft, absorbent, flexible covering with a surface that will neither
stick nor slide when applied, for example, to an open wound. The
absorbent covering may act either as an applicator of medicaments
in combination with the conduit for temperature control, or it may
be wetted with a sterile fluid to enhance the heat transfer
relation between the conduit and area of application, or it may act
as an absorbent bandage or dressing or as a surgical sponge. Unlike
the present invention, this apparatus requires the manufacture of a
complicated water tight, serpentine conduit layer making it
expensive to produce commercially.
[0010] U.S. Pat. No. 4,872,593 to Behringer discloses an apparatus
for the storage and dispensing of packaged adhesive bandages and
similarly shaped flat packaged units. The dispenser includes a
drive unit that may be powered either manually or electrically. A
weight is provided to exert downward pressure against the bandages
toward the cartridge floor. The apparatus requires a removable
cartridge to hold the stack of packaged adhesive bandages and the
weight. The apparatus also requires a roller with an elastic
following finger attached to the roller so that when the roller is
rotated the following finger frictionally engages the lowermost
bandage in the stack.
[0011] The instant invention does not require an elastic following
finger, as this is difficult to rotate as the elastic finger
frictionally engages the inside surfaces of the base as well as the
bandages as it completes a revolution, therefore, requiring more
applied torque. The actuator of the instant invention is a simple
and elegant design that eliminates the need for additional
following finger, making is more economical to manufacture.
[0012] U.S. Pat. No. 4,495,402 to Burdick et al., disclose a warmer
for heating wet dressings and other articles disposed in a combined
heating and storage compartment in stacked relation so that the
bottommost article is dispensed through an opening is at a proper
temperature.
[0013] U.S. Pat. No. 5,210,396 to Sanders discloses a baby wipe
warmer apparatus to receive a baby wipe box therein to heat baby
wipes and includes a container heater assembly. The wipe container
assembly includes a container body member with a container lid
member pivotally connected thereto. The container heater assembly
heats all sides of the baby wipe box. The container lid member has
connector members whereupon it can be sealed to the container body
member though zipper members or VELCRO fasteners. The main lid body
has a central dispenser opening that can be closed by VELCRO
fasteners or pen to allow dispensing of baby wipes therethrough.
However, these patents fail to disclose an actuator, disposed
proximate the opening, that is able to frictionally engage and urge
one of wet dressings through the opening.
[0014] None of aforementioned prior art teach or suggest a portable
medical pad dispenser able to store and dispense medical pads as
desired. In addition, no known prior art discloses a portable
medical pad dispenser further comprising a heating means for
maintaining medical pads therein at the desired temperature.
SUMMARY OF THE INVENTION
[0015] The present invention makes use of a portable container
adapted to store and dispense medical pads stored therein. The
portable container is stored within a medical warming pad holding
system. The container comprising a body with an interior cavity
having an upper access opening, the interior cavity constructed and
arranged to accept different types or sizes of medical pad therein.
The container having a lid attached to the body for movement
between a first position providing at least partial access to the
interior cavity of the container in order that additional medical
pads may be placed within the interior cavity, and a second
position at which the lid
[0016] The opening is constructed and arranged to allow passage of
at least one of the medical pads therein. Moreover, the opening can
be located between either the junction of lid and one of the
sidewalls, or between the junction of one of the sidewalls and the
bottom panel. The container includes an actuator disposed proximate
the opening and adapted to frictionally engage and urge one of the
medical pads through the opening. Moreover, the container includes
at least one biasing means disposed within the interior cavity and
attached to the container body opposite the opening, whereby the at
least one biasing means exerts a force urging the medical pads
toward the actuator such that the medical pad nearest the actuator
is dispensable through the opening upon operation of the actuator
by the user.
[0017] In one embodiment, the interior cavity of the container can
include multiple compartments formed by dividing the interior
cavity. Each compartment can include different types of medical
pads therein. For example, the interior can be divided into two
separate compartments, wherein one compartment includes individual
medical pads containing alcohol or betadine and the other
compartment includes flexible bandages (i.e., BAND-AID, packaged
gauze). This configuration can be particularly advantageous as the
clinician will be able to first dispense an alcohol or betadine pad
from the first compartment for sterilizing the patient's venous
access access site, then after removal of the needle, the clinician
is can dispense a flexible bandage from the second compartment for
immediate application to the punctured access site.
[0018] In another embodiment, the portable container includes a
heating means in thermal communication with the container body for
providing heat and maintaining the medical pads at a desired
temperature, while the individual container is located outside the
medical warming pad case. The heating means can be either an
electrically conductive wire in thermal communication with the
container body, or a fluid conduit system that substantially
surrounds the container body. Moreover, the power source used to
operate the actuator and/or heating means can be from either
conventional 110 V AC power supply or 12 V DC (e.g., battery,
vehicle cigarette lighter).
[0019] Accordingly, it is an objective of the instant invention to
teach a dispenser able to dispense medical pads and/or bandages of
various sizes.
[0020] Another objective of the instant invention is to teach a
portable container able to accurately and reproducibly control the
temperature of the medical pads housed therein.
[0021] It is yet another objective of the present invention to
teach a disperser able to dispense at least two different types of
individual medical pads (e.g., alcohol or betadine) and/or flexible
bandages (i.e., BAND-AID).
[0022] Another objective of the instant invention is to provide a
portable container that is economical to manufacture in that it has
few components.
[0023] It is a further objective of the instant invention to teach
a portable container able to warm the medical pads to a maximum
temperature of about 131 degrees F. (55 degrees C.) and can be
utilized on patients from neonates to geriatrics.
[0024] It is still another objective of the instant invention to
provide one embodiment of the container having at least one easy to
read LCD display able to show general operating instructions,
cleaning instructions, calibration instructions, etc. In addition,
the display can indicate to the user when container is empty and
the "set" and "actual" temperatures of the container.
[0025] It is an additional objective of the instant invention to
provide one embodiment of the container body having at least one
control button or keypad.
[0026] It is a yet another objective of the instant invention to
provide one embodiment of the container that includes a program or
control logic able to receive inputs from the a key pad on the
container body, such as the patient's age, wherein the program or
control logic recommends an age appropriate temperature
setting.
[0027] Other objects and advantages of this invention will become
apparent from the following description, wherein are set forth, by
way of illustration and example, certain embodiments of this
invention.

therein.
[0043] The heated case 10 includes internal heat source (not shown)
used to provide controlled heat to the medical pads (e.g., alcohol
pads, betadine pads, flexible bandages or the like). The portable
containers 12 allow the user to readily transport the warmed
medical pads to various locations, (e.g., patient's room, operating
room, ambulance, etc.) Preferably, the medical pads are
hermetically sealed containing a disposable, absorbent material
impregnated with at least one anti-microbial component (e.g.,
alcohol, betadine, etc.,). However, the medical pads could include
flexible bandages (i.e., BAND-AID), unpackaged pads, or gauze
saturated with at least one anti-microbial component.
[0044] FIG. 2 illustrates an upper perspective view of one
embodiment of the portable container separated from the interior of
the stationary heated case 10. By way of an overview, the portable
containers include a container body 16 with an integrally formed
actuator 20 for frictionally engaging and urging a medical pad
through an opening 42 in the container, see FIG. 2b. The interior
of the container includes at least one biasing means 22 disposed

[0046] The insulated lid 14 is attached to the container body for
movement between a first position (FIG. 2a) at which the lid
provides at least partial access to the interior cavity such that
the medical pads may be placed within said interior cavity, and a
second position (FIG. 2b) wherein the lid precludes access to the
interior, thereby reducing possible contamination of the
container's interior and provide additional insulation.
[0047] The container body further includes an opening 42 (FIG. 2b)
constructed and arranged to allow passage of a least a portion of
one of the medical pads outside the interior cavity such that the
user can easily grip the external portion of the medical pad. In
the embodiments of FIGS. 2a-6, the opening is shown located between
the lid and one of the sidewalls, however, the opening can be
located between one of the sidewalls and the bottom panel for
dispensing the medical pads proximate the bottom of the container
(not shown).
[0048] FIGS. 3-6 illustrate different types of actuators that can
be used in the instant invention. Each actuator is disposed
proximate the opening 42 and constructed and arranged to
frictionally engage and urge one of the medical pads
therethrough.
[0049] In the embodiment of FIGS. 2a-3, the actuator is shown as
simply a roller 44 that partially extends into the interior cavity
40 of the container. The roller is formed from, or externally
coated with a heat resistant elastic material designed to
frictionally engage and urge the nearest of the medical pads
through the opening upon counter-clockwise rotation of the external
portion of the roller by the user's finger or thumb.
[0050] Examples of heat-resistant elastic material include, albeit
not limited to, natural rubber, synthetic rubber, silicon, mixtures
or combinations thereof. Moreover, the elastic material can include
ridges or other means of gripping, such as knurling (not shown)
that will allow the user to easily rotate the roller.
[0051] In an alternative embodiment not shown, the actuator 20
could comprise a lever that, like the roller, partially extends
into the interior cavity. One end of the lever inside the cavity is
coated with the heat-resistant elastic material to engage the
medical pad. The user simply moves the external portion of the
lever up to push the medical pads therethrough.
[0052] FIG. 4 illustrates a different actuator as seen from an
upper perspective view, the actuator 20 comprises a toothed member
46 shown as a first circular gear that partially extends into the
interior cavity of the container. The first circular gear is
rotatably attached to the inner surfaces of opposing sidewalls of
the container by an axle 114. The first circular gear is in
operable connection with a second circular gear member 48 also
rotatably attached to the inner surface of the container by an axle
116. The second gear member is in turn, integrally connected via
the axle 116 to elastic roller 44 like the one in FIGS. 1-2b,
whereby rotation of first gear by the user causes the second gear
member to rotate and frictionally engage and urge the nearest of
the medical pads through the container opening.
[0053] FIG. 5 illustrates a manual push-button configuration. In
this embodiment the toothed member 46 is depicted as a rod with a
button portion 50 located external to, and outwardly biased by a
spring 52 that acts against the exterior surface of the container
body. The toothed member includes a toothed portion 54 located
within the interior cavity, wherein the toothed portion engages and
rotates a second gear member 48, rotatably attached to opposing
sidewalls of the container by an axle 116, similar to FIG. 4. Thus,
when the user manually presses the button portion toward the
exterior surface of the container, (i.e. inwardly) a single medical
pad is extracted from the container's interior.
[0054] The embodiments of FIGS. 4 and 5, are advantageous as these
configurations reduce direct contact by the user into the interior
cavity of the container, hence, reducing the likelihood of
contaminating the medical pads contained therein. In the
aforementioned embodiments of FIGS. 4 and 5, although not shown
herein, the second gear member and roller could be formed as single
a combination smooth and toothed roller, whereby the toothed member
engages the toothed portion of the roller and the smooth portion
acts to frictionally engage the medical pads.
[0055] In another embodiment shown in FIG. 6, the actuator is an
elastic roller 44 similar to the aforementioned embodiments, the
roller is operatively connected to an electric motor 56 in
electrical communication through a circuit (not shown) with a power
source (e.g., car battery, rechargeable batteries, 110/120 V) via a
switch 58 partially located within the interior cavity of the
container. The actuator is derived by the electric motor by a
pulley 118 as well known in the art. The actuator further includes
an interruption means 60 to interrupt the power from the power
source to the electric motor. Preferably, the interrupting means is
a pin 60 integrally attached to the roller and projects along the
axis of rotation of the roller, whereby rotation of the roller
through one complete revolution causes the pin to trip the switch
58 and open the circuit such that power to the motor is disrupted.
Thus, when a medical pad is desired the user simply presses the
switch inward thereby completing the circuit, which causes the
roller to rotate one complete revolution and stop, automatically
expelling a single medical pad.
[0056] All of the aforesaid embodiments herein include at least one
biasing means 22 is disposed within the interior cavity. The
biasing means are attached to interior surfaces of the container
body opposite the opening. The biasing means exerts a force urging
the medical pads toward the actuator 20 such that the medical pad
nearest the actuator is dispensable through the opening upon
operation of the actuator by the user. The biasing means is shown
in FIGS. 1-6 as a helical spring, however, any functionally
equivalent means of biasing the medical pads can be used, for
instance, a leaf spring.
[0057] Further, the biasing means are attached to or retained
within the container body by any means known in the art, for
example, albeit not limited to, recesses, capture means, welding,
adhesives, etc. The other end of the biasing means may be retained
directly against the medical pads or against a follower plate 62,
by any means of attachment known in the art. The follower plate is
disposed within the interior cavity and sized to substantially
extend the distance of the inner surface of the opposing sidewalls,
such that the biasing means exerts a force between the container
body and the follower plate.
[0058] In the embodiments of FIGS. 3-6, the lid 24 is attached to
the container body by at least one pivot means shown here as hinges
64, however pins, axles or any other functionally equivalent
structure known in the art can be used without departing from the
scope of the invention.
[0059] Alternatively, as shown in FIGS. 2a-2b, the lid could be
slidingly attached to first end 26 of the container body. In one
embodiment, the upper periphery of one pair of opposing sidewalls
includes a channel 66 constructed and arranged to receive the width
of the lid 24, so that lid is readily translated by the user
between a first position and a second position along the at least
one pair of opposing sidewall channels.
[0060] Conversely, it is contemplated herein that the outer
periphery of the lid could include a channel constructed and
arranged to receive a projection integrally connected to one pair
of opposing sidewalls for translation between the first and second
position along the projections (not shown). When the opening is
located between the lid and the container sidewall, these
embodiments allow the user to adjust the position of the lid to
provide the desired sized opening to expel the medical pads housed
therein.
[0061] Referring now to FIGS. 7-8, the portable containers of any
of the aforementioned embodiments can further include a heating
system with various heating means in thermal communication with the
container body for maintaining the medical pads therein at a
desired temperature when located outside the stationary heated case
2.
[0062] In the embodiment shown in FIG. 7, the heating means
comprises an electrically conductive wire 72 embedded within, and
substantially surrounding the container body 16. At least one of
the sidewalls, bottom panel, follower or lid can made of, or
comprise a thermally conductive layer (i.e., aluminum) well known
to those skilled in the art. In addition, at least one of the
sidewalls, bottom panel, follower or lid could made of, or comprise
a thermally-insulated outer layer 70 well known in the art (i.e.,
plastic).
[0063] The heating system further includes a releasable connector
means 74 and a means for supplying power 76 to the electrically
conductive wire 72 via the releasable connector means. In one
embodiment, the means for supplying power includes a power wire
connected at a first end to the releasable connector means and a
second end adapted to connect to a vehicle cigarette lighter to
link the heating system to an automobile's 12 Volt DC power supply,
as well known in the art. This configuration is useful when the
container is transported in a vehicle (i.e., ambulance) and the
temperature falls below that desired, for example 90.degree. F. The
releasble connector include an transformer/adapter so that the user
can place the means for supplying power into a standard AC/DC
electrical outlet (not shown) when not connected to a vehicle
cigarette lighter.
[0064] In addition, the means for supplying power could include
comprises a battery unit 78. The battery unit could be embedded
within anywhere in the container body 16 such that it is accessible
to the user via an access panel (not shown) and include the
appropriate batteries. Preferably, the batteries would be
rechargeable by the means for supplying power 76.
[0065] In particularly preferred embodiment the heating system of
FIGS. 7-8, includes a temperature control means. The temperature
control means includes at least one power switch 82 in electrical
communication with the means for supplying power 76. The switch is
positional between the open and closed position to regulate the
flow of electricity to the electrically conductive wire 72.
Moreover, the switch 82 can be located anywhere on the container
body and can be configured to turn the heating means off when the
container body is placed within the stationary heated case 2.
[0066] Preferably, the temperature control system includes at least
one thermostat 102. The thermostat (only one is shown) is
electrical communication with the means to supply power 76, switch
82, and at least one temperature setting means 84 in by electrical
circuit shown in FIG. 8. The thermostat acts to regulate the supply
of electrical current through the electrically conductive wire 72.
That is, when the temperature measured by the thermostat inside the
interior cavity rises above the desired temperature entered by the
user through the temperature setting means 84, the thermostat
interrupts the flow of electricity by opening the switch 82,
breaking the connection to the conductive wire.
[0067] In alternative embodiment shown in FIG. 9, the heating means
comprises a fluid conduit system in thermal communication with the
container body. The conduit system includes conduit 120 embedded
within the container (FIG. 9) or it can surround the outside of the
container body (not shown). The fluid conduit system has a fluidic
inlet 86 for receiving a heated fluid and a fluidic outlet 88 for
discharging the heated fluid from the conduit system. The fluid
conduit system includes a first connection means 90 for releasably
attaching the fluid inlet to a supply hose 92 commonly found a
vehicle engine coolant system (shown generally as 94) and a second
releasable connection means 96 for releasably attaching the fluid
outlet 88 with a return hose 98 found in the engine coolant system
94.
[0068] As with the electrical heating system described with respect
to FIGS. 7-8, the fluid conduit system can include a temperature
control means comprising a temperature control valve 100 located in
fluid communication with the first connection means 90 and
translates between an "open" and a "closed" position to regulate
the flow of heated fluid through the conduit 120 based upon the
output of at least one thermostat 102 inside the interior cavity.
The temperature control means having at least one temperature
setting means 84 in electrical communication with at least one of
the thermostats 102.
[0069] As with the previous embodiment, the temperature setting
means 84 is in electrical communication with a power switch 82 and
the thermostat 102. This simple configuration allows the user to
set and adjust the temperature control means to the desired
temperature. Preferably, the temperature control system is liked to
the vehicle cigarette lighter in electrical communication with an
automobile's 12 Volt DC power supply to regulate the position of
temperature control valve.
[0070] As shown in FIG. 10, any of abovementioned heating systems
with the temperature setting means 84 can include least one control
button or keypad located on the container body, wherein the user
enters the desired temperature. An example of some control buttons
include, albeit not limited to, a "SET" button 122, "UP" arrow
button 124, "DOWN" arrow button 126 and "STANDBY" button 134.
[0071] The user can change the temperature in the following manner:
[0072] 1) Press "SET" button 122; [0073] 2) Press "UP" arrow button
124 to increase temperature; [0074] 3) Press "DOWN" arrow button
126 to decrease temperature; [0075] 4) Press "SET" button when
desired temperature displays on an liquid crystal display (LCD)
110;
[0076] wherein the LCD can prompt the user through the steps 1-4
above while indicating the "SET" temperature and the "ACTUAL"
temperature.
[0077] Moreover, the program or control logic can receive inputs
entered by these control buttons or keypad such as the patient's
age, wherein the program or control logic shows the recommend an
age appropriate temperature setting on the LCD. The program or
control logic could also include a non-volatile memory means used
to store and display general operating instructions, cleaning
instructions, inspection and maintenance instructions or other
additional instructions.
[0078] Moreover, the container can include a plurality of LCDs or
different colored LEDs that indicate when the desired "set"
temperature entered by the user, is reached and an "actual"
temperature, as measured by the thermostat 102. For example, a
green LED 130 will light when the temperature control means is on
and warming to desired temperature. A yellow LED light 132
indicates the container's interior has reached the desire
temperature.
[0079] Furthermore, as shown in FIGS.7 and 9, the interior cavity
can include a position sensor 112 situated proximate the opening
and arranged to detect the follower 62 once it reaches a location
near the opening. The position sensor can be electrical
communication with the control logic/program which can then display
"REFILL" or the like on the LCD 110, thereby indicating to the user
that container is empty or nearly empty of medical pads.
[0080] As shown in FIG. 10, the heating system could further
comprise a container holder 80 constructed and arranged to retain
the container body 16 in a substantially vertical, or upright
position. The holder is constructed and arranged such that is can
be either mounted within an automobile or placed on a tabletop.
Furthermore, the holder can be adapted to house the releasable
connector means 74 to provide electrical communication to the
heating system and/or rechargeable batteries from the means for
supplying power 76.
[0081] In another embodiment shown in FIG. 12, the portable
container can dispense different types of medical pads therein. For
example, the interior cavity can be divided into a plurality of
separate compartments 104, 106 constructed and arranged to accept
different types of medical pads. The compartments each having an
actuator 20A, 20B located proximate an opening to the exterior, to
frictionally engage and urge one of the medical pads contained in
the compartment through the opening.
[0082] Each of the compartments includes at least one biasing means
52 disposed therein, opposite the opening. This design allows the
user to transport two different medical pads therein. For instance,
the clinician can first dispense an appropriate anti-microbial
medical pad from a first compartment of the container that is used
to swab the venous access site prior to performing venipuncture.
Next, the clinician can dispense a flexible bandage contained in a
second compartment of container to protect the access site.
[0083] Moreover, any of aforementioned embodiments of the container
can include an indention 134 molded into the container body
proximate the opening for receiving the user's finger or thumb
during the dispensing operation, see for example FIG. 2a-b.
[0084] As shown in FIG. 11, when loading any of the disclosed
embodiments with additional medical pads, the user can merely place
the lid at the second position and use one of their fingers (i.e.,
thumb) to urge the biasing means and/or follower toward the
sidewall of the container to which it is attached. The other hand
can then place the new medical pads in the cavity between the
follower and the opening.
