Description
BACKGROUND OF THE INVENTION
The present invention relates to new and improved intravenous
containers, and it more particularly relates to an intravenous
system for adding medications or other ingredients to the contents
of a flexible-plastic intravenous container for packaging and
feeding its contents to a patient.
When an intravenous fluid, such as a saline solution, is to be
administered from an intravenous bottle to a patient, it frequently
becomes necessary to add a medication, such as a vitamin
supplement, to the intravenous solution. For example, in adding a
vitamin supplement to a saline solution in an intravenous bottle, a
small quantity of saline solution is injected with a suitable
instrument, such as a hypodermic syringe, into a sterilized vial of
the powdered vitamin supplement to dissolve it in the saline
solution. The vitamin-saline solution can then be transferred from
the vial to the intravenous bottle by means of the syringe.
Therefore, it would be desirable to have a more simple and direct
system for adding a medication to the contents of an intravenous
container.
Therefore, it is the principle object of the present invention to
provide a new and improved intravenous container.
Another object of the present invention is to provide a new and
improved system for adding a medication to an intravenous
fluid.
SUMMARY OF THE INVENTION
Briefly, the above and further objects of the present invention may
be realized in accordance with the present invention by providing a
flexible intravenous container having a flexible tubular container
member which has each of its ends aseptically sealed together to
provide a sealed package for an intravenous fluid and which has an
outlet connector at a point midway between its ends to connect an
intravenous tube in fluid communication with the container member.
The ends of the container member are adapted to be attached to a
support stand so that the container member can be folded over at
its midpoint and its ends can be readily attached to the support
stand whereby the outlet connector is disposed at the bottom of the
container. At least one additive connector is provided near one of
its ends so that a medication container can be interconnected with
the container member. Where the medication to be added is in
powdered form, such as a vitamin supplement, and the intravenous
fluid is a saline solution, a vial containing the vitamin
supplement can be interconnected to the additive connector so that
an attendant can squeeze the flexible container member to force a
small quantity of the saline solution into the medication container
to mix with the powdered vitamin. Upon releasing the container
member, the vitamin-saline solution is drawn from the vial into the
container member as a result of the suction which is created by the
container member.
The intravenous container of the present invention is not bulky to
use, and thus it can be easily handled and mounted on a support
stand. Moreover, the inventive container can be readily hung on the
stand before the medication is added to the contents of the
container. Due to the unique construction of the container, it can
be completely emptied, and it does not require an air vent since
the container is composed of a flexible material. Furthermore, the
container of the present invention is easily and inexpensively
manufactured by in line techniques so that it can be made as a
disposable item.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE
INVENTION
Referring now to the drawings, and more particularly to FIG. 1
thereof, there is shown a flexible intravenous container 10 which
embodies the principles of the present invention and which is
mounted on a support stand 12. The container 10 includes a sealed,
flexible bag 14 which contains an intravenous fluid and which is
hung by its apertured ends 16 and 18 from a hook 20 on the stand
12. In order to mount the container 10 on the stand 12, first the
end 18 is slipped over the end of the hook 20, and then the bag 14
is folded over and its other end 16 is slipped over the end of the
hook 20. As shown in FIG. 1, an outlet connector 22 at the bottom
of the bag 14 is adapted to receive a tube connector 24 of an
intravenous tube 26 to connect it in fluid communication with the
inside of the bag. In order to add a medication to the intravenous
fluid in the bag 14, a vial (not shown) containing a medication can
be interconnected to one of a pair of additive connector assemblies
28 and 31 which are located near the respective ends 16 and 18 of
the bag 14. The connector assembly 28 can accommodate a vial (not
shown) which has a male connector and which is commonly known as a
Travenol package. The connector assembly 31 can be used with a vial
(not shown) which has a female connector and is commonly known as a
Squibb package.
In use, a medication vial is interconnected with one of the
connector assemblies, such as the connector assembly 28. If the
medication in the vial is in powdered form, the bag 14 is
compressed by the attendant to force a small quantity of the
intravenous fluid into the vial to dissolve the powdered medication
contained therein. After shaking the vial to dissolve the powder,
as a result of the suction produced when the bag 14 is released,
the medication solution is transferred from the vial to the bag 14
to mix with the remaining fluid contained therein. If the
medication is in liquid form, the bag 14 is first squeezed, and
then the vial is interconnected with one of the additive connectors
of the bag 14 so that when the bag 14 is released, the medication
is drawn into the bag.
Referring now to FIGS. 2 and 3 of the drawings, the bag 14 is a
seamless, extruded plastic tube which is composed of a thin plastic
film, such as a three-ply film composed of polyethylene at the
outer layers and mylar at the middle layer. However, it is to be
understood that the bag 14 could also be formed in different
manners, such as by forming the bag of two sheets of thin plastic
film which are heat sealed together along their side marginal
edges. One of the ends 16 and 18 of the tubular bag 14 is heat
welded together to form a container, and the other end is left open
to fill the container with an intravenous fluid. The bag 14 is
filled to a level which is slightly below the additive connector
assemblies 28 and 31 when the intravenous container 10 is mounted
on the stand 12 as shown in FIG. 1. After filling, the open end may
then be closed by heat welding to complete the package. Each of the
ends 16 and 18 has a centrally disposed hole 33 for receiving the
hook 20 on the stand 12.
As shown in FIGS. 2 and 3, the outlet connector 22 is heat welded
to the bag 14 midway between the ends 16 and 18 in line with the
holes 33 therein. The connector 22 is tubular in shape and is heat
welded over a hole 35 in the bag 14. An axial hole 37 in the
connector 22 is aligned with the hole 35, and an annular flange 39
surrounding the hole 37 is heat welded to the outer surface of bag
14. A protective cap 41 is disposed over and conforms to the shape
of the outer end of the connector 22 and has an annular flange 43
which abuts the flange 39 and surrounds the open end of the cap 41
for removing it from the connector 22. The cap 41 includes a
centrally disposed depending portion 45 which extends into the hole
37 to seal the connector 22. An internal annular groove 47 receives
a complementary-shaped annular bead or ridge 49 surrounding the end
of the depending member 45 to lock the cap 41 on the connector 22.
The depending member 45 abuts a membrane portion 52 which is
integrally formed in the connector 22 and extends across and blocks
the hole 37. The membrane 52 permits the cap 41 to be removed while
the bag 14 is mounted on the support 12 since the membrane 52
provides a second aseptic seal which prevents the fluid from
leaving the bag 14. When the cap 41 is removed from the connector
22, the complementary-shaped connector 24 of the intravenous tube
26 may be inserted into the connector 22. The tube connector 24 on
the vial includes a cutting edge (not shown) to pierce the membrane
52. The ruptured membrane serves the purpose of sealing the tube
connector 24 in the outlet connector 22. The tube connector 24
includes a complementary-shaped annular ridge (not shown) which
slips into the internal annular groove 47 of the connector 22 to
interlock it with the tube connector 24, whereby when the bag 14 is
compressed, the tube connector 24 is not forced out of engagement
with the connector 22.
The connector 22 is composed of a plastic material, such as linear
polyethene. The protective cap 41 may be formed of vinyl or a vinyl
compound such as ethylvinylacetate acid by E. I. duPont de Nemours
& Co., under the name, E. V. A. The connector member 22 is
injection molded directly into the cap 41 so that the cap 41 is
aseptically seals the connector 22. A process for such an injection
molding process is disclosed in detail in my copending U.S.
application, Ser. No. 763,097, filed on Sept. 27, 1968, entitled
"Aseptic Connector and Closure Assembly".
The connector assembly 28 includes a connector 54, which is
substantially identical to the connector 22, and a protective cap
56 which fits over the connector member 54 and is substantially
identical to the protective cap 41. The connector member 54 has an
axial hole 58 which is aligned with a hole 60 located near and in
line with the hole 33 in the end 16 of the bag 14. The connector 54
is thus adapted to interconnect with a connector (not shown) of a
medication vial in the same manner as the connector 22
interconnects with the tube connector 24.
The connector assembly 31 comprises a connector 62 which has a
protective cap 64 disposed over and conforming to the surface of
the outer end of the connector 62. The connector 62 is tubular in
shape and has an axial hole 66 extending therethrough in alignment
with a hole 68 which is located near and in alignment with the hole
33 in the end 18 of the bag 14. The connector 62 includes an
annular flange 71 which is heat welded to the bag 14. The outer end
73 of the connector 62 is cut on a bias to provide a cutting edge
to pierce a diaphragm or membrane (not shown) on a medication vial
when the two containers are interconnected.
The cap 64 includes a centrally disposed depending portion 75 which
extends into the open end 73 to seal the connector 62. The
connector 62 further includes an annular flange 77 which is
disposed adjacent the annular flange 62 to permit the cap 64 to be
removed from the connector 62. On the inside of the connector 62
opposite the outer annular flange 77 is an annular ridge or bead 79
which fits into a complementary-shaped annular groove 81 in the
outer edge of the connector 62 adjacent the annular flange 71 to
lock the cap 64 on the connector 62 and to receive a
complementary-shaped annular bead (not shown) on the connector of
the medication vial. An enlarged portion 83 of the cap 64 adjacent
the bead 79 receives an annular boss or collar 83 which provides a
stop member for the connector of the medication bottle.
The connector assembly 31 may be formed of the same material and in
the same manner as the outlet connector 22 and its cap 41 so that
an aseptic and hermetic seal is formed between the cap 64 and the
connector 62.
Referring now to FIG. 4, there is shown a cross-sectional view of
another intravenous container 90 in accordance with the present
invention. The container 90 is similar to the container 10, but the
container 90 is formed of a single sheet 92 of flexible plastic
material which is folded over longitudinally and heat welded
together at a seam 94 and which has the connector assemblies, such
as a connector assembly 96, heat welded to its outer surface
opposite to the seam 94. In order to permit the empty container 90
to occupy a minimum amount of space, a pair of V-shaped bellow-type
gussets 98 in the form of pleats or folds extend along each side of
the container 90. When the container 90 is filled, the gussets 98
unfold to increase the capacity of the container 90
accordingly.
While the present invention has been described in connection with
particular embodiments thereof, it will be understood that those
skilled in the art may make many changes and modifications without
departing from the true spirit and scope of this invention, and
accordingly all such changes and modifications which fall within
the true spirit and scope of this invention are intended to be
covered in the appended claims.
