Description
TECHNICAL FIELD
[0001] The present invention relates to a bed for a patient, and
more particularly to a bed for a patient in which a drainage unit
for a chamber pot and a cover unit are simplified to reduce
manufacture costs.
BACKGROUND ART
[0002] Generally, various beds for patients are known in the art,
and the present invention provides an improvement of such a bed for
a patient, which allows a patient to relieve nature in the bed.
[0003] A common bed for a patient includes a bed frame, protection
frames lifted at both sides of the bed frame, a mattress placed in
these frames for a patient to lie down thereon, and a table
rotatable at one side of the bed to be rotatable thereon. In
addition, a mattress control handle is installed in a lower space
of the bed to stand a lower or upper portion of the mattress.
[0004] However, in case that a patient not easily moving gets along
on the bed for a patient, the patient may not go to a toilet due to
the inconvenient behavior and he/she should relieve nature using a
separate bedpan by help of a guardian on the bed.
[0005] However, in order to solve the physiological function, many
difficulties are generated to the guardian as well as the patient
to suit the bedpan to the patient.
[0006] Accordingly, various means have been proposed to solve the
above problems.
[0007] One example is disclosed in Korean Utility Model
Registration No. 306230, invented by the same inventor of this
application. This utility model is directed to relieving nature on
a mattress, wherein a case including a forward/rearward moving body
provided with a chamber pot and a sealing body, which are moved
forward or rearward and lifted by a moving means and a lifting
means provided therein to be selectively inserted into a through
hole formed in a mattress, is connected and fixed to a bed frame
below the through hole.
[0008] According to the above configuration, the sealing body is
inserted into the through hole at ordinary times so as to give a
common bed function. At this time, if a patient desires to relieve
nature, he/she pushes a manipulation button, and then the sealing
body descends by the lifting means according to the signal and then
deviates from the through hole. In addition, as the moving means is
operated, the moving body is moved rearward along rails provided in
the case. The chamber pot is then lifted into the through hole by
means of the lifting means.
[0009] After the chamber pot is inserted as mentioned above and the
patient relieves nature, the above procedures are progressed to the
contrary so that the sealing body is lifted into the through hole.
The chamber pot retrieved according to the above process is than
taken out by a nurse from the side of the bed, then managed, washed
and then recombined for the next use.
[0010] However, if there is no nurse beside the patient who uses
the bed for a patient, excrement of the patient is not treated
until the nurse comes back, which causes bed smell in the indoor
space and results in uneasiness to the patient and other
persons.
[0011] In addition, a nurse should treat the chamber pot containing
excrement by himself/herself as in the conventional bed. Moreover,
since the chamber pot is positioned below the bed, it is
inconvenient to recombine the chamber pot to the bed after
washing.
[0012] Accordingly, Korean Utility Model Registration No. 343449,
invented by the inventor of this application to solve the above
problems, is disclosed. This technique includes a bed having a
mattress with a through hole vertically formed at its center and a
frame supporting the mattress and including a plurality of legs; a
excretion case connected and fixed to the frame below the through
hole and including a forward/rearward moving body provided with a
chamber pot and a sealing body moved forward or rearward and lifted
by means of an operating means provided therein to be selectively
inserted into the through hole; a cover means provided at the front
of the excrement case and having a cover for sealing an upper
portion of the chamber pot when the forward/rearward moving body is
advanced; and a washing means for supplying washing water to a
lower portion of the cover and draining the washing water filled in
the chamber pot.
[0013] Thus, the bed for a patient configured as above allows a
user to relieve nature without moving hardly since the sealing body
and the chamber pot are linked and inserted/taken out through the
through hole in a lower space of the mattress with the through hole
by means of simple manipulation. In particular, after relieving
nature, excrement contained in the chamber pot is cleanly treated
by means of the washing means, so a nurse may not treat the chamber
pot directly and the indoor circumstance may be kept agreeably.
[0014] However, the washing means includes a plurality of through
holes formed in the cover, a washing water supply pipe fixed to an
upper portion of the cover and having a plurality of nozzles
inserted into the through holes to inject washing water into a
chamber pot from outside, a discharge pipe provided to a lower
portion of one side of the chamber pot to discharge wasted water
filled in the chamber pot, and a collecting vessel having an
opening in its upper portion so that the discharge pipe is inserted
therein through the opening and to which a drainage pipe for
draining out wasted water introduced through the discharge pipe is
connected.
[0015] At this time, since the discharge pipe provided to the
chamber pot and the collecting vessel connected to the discharge
pipe are connected in a complex way, manufacture costs for the
washing means are too high.
[0016] In addition, since wasted water is always filled in the
collecting vessel, bad smell is generated in the indoor space.

[0036] In addition, the operating means 23 further includes a
manipulation panel 234 (see FIG. 1) provided to one side of the bed
1 to operate the forward/rearward moving motor 231b and the lifting
motors 232b, 233b.
[0037] Hereinafter, operation of the bed for a patient according to
the present invention is described as follows.
[0038] As shown in FIGS. 1 to 3, when a patient relieves nature
with lying down, the patient or a nurse manipulates the
manipulation panel 234 so that the chamber pot 21 is inserted into
the through hole 121 formed in the mattress 12, and then the
patient may relieve nature.
[0039] After the patient relieves nature, the manipulation panel
234 is manipulated so that the chamber pot 21 is deviated from the
through hole 121 and the sealing body 22 is inserted therein
instead of the chamber pot 21. Then, the chamber pot 21 is deviated
below the through hole 121 and descended to the forward/rearward
moving body 2, and the chamber pot 21 is advanced toward the cover
plate 4 by means of forward movement of the forward/rearward moving
body 2.
[0040] Then, the insert grooves 42 formed in both sides of the
chamber pot 21 are horizontally inserted into the cover plate 4
provided at the front of the case 3, which makes the upper portion
of the chamber pot 21 sealed.
[0041] After relieving nature, the opening/closing switch 522 fixed
to one side of the bed 1 is operated to open the opening/closing
valve 521 of the water supply pipe 51, and then washing water is
supplied to the chamber pot 21 through the water supply pipe 51.
The supplied washing water is injected into the chamber pot at high
pressure through the injection nozzles 53 provided to the cover
plate 4. Then, the injected washing water pulverizes excrement
contained in the chamber pot 21 and washes inside of the chamber
pot. After washing the inside of the chamber pot, the wasted water
passes the drainage means 6 provided to the lower portion of one
side of the chamber pot and is then discharged to a water-purifier
tank through the external draining pipe 7.
[0042] That is to say, the drainage means 6 is capable of draining
out wasted water in the chamber pot 21 that is lifted and moved
forward/rearward, as shown in FIG. 2. In addition, since the
drainage means 6 is connected to the external draining pipe 7
provided to the lower portion of the chamber pot 21 through the
forward/rearward moving body 2 and the case 3 and is composed of a
plurality of length-adjustable pipes, the drainage means 6 is
shrunken together when the chamber pot 21 is lifted or moved
forward or rearward.
[0043] To describe operation of the drainage means 6 in more
detail, when the chamber pot 21 is lifted, the first draining pipe
61 is lifted inside the vertical pipe 621 of the second draining
pipe 62, so the length of the first draining pipe 61 may be varied.
In addition, if the forward/rearward moving body 2 is moved forward
or rearward, the horizontal pipe 622 of the second draining pipe 62
is moved inside the third draining pipe 63, so the length of the
horizontal pipe 622 may be varied.
[0044] Thus, in case that the chamber pot 21 is lifted or moved
forward/rearward, lengths of connection portions between the first
and second draining pipes 61, 62 and between the second and third
draining pipes 62, 63 are varied, so wasted water filled in the
chamber pot 21 may be easily discharged through the drainage means
6 composed of the length-adjustable first, second and third
draining pipes 61, 62, 63.
[0045] In addition, since a plurality of packings 64 are provided
to the connection portions of the first, second and third draining
pipes 61, 62, 63, it is prevented that wasted water is leaked
out.
[0046] Meanwhile, FIG. 4 shows an opening/closing means according
to another embodiment of the present invention. The opening/closing
means 52 of this embodiment includes an opening/closing valve 523
provided to the water supply pipe, an opening switch 524 provided
to an inner side of a front plate of the case 3 and operated by
advance of the forward/rearward moving body 2 to open the
opening/closing valve 523, and a closing switch 525 provided to the
bed 1 to close the opening/closing valve 523 by manual operation of
a patient or a nurse.
[0047] Thus, if a patient moves the forward/rearward moving body 2
forward by manipulation of the manipulation panel 234 after
relieving nature, the cover plate 4 covers the upper portion of the
chamber pot 21. Also, at the same time, the front portion of the
forward/rearward moving body 2 pushes the opening switch 534 of the
water putting unit 5, provided to the inner side of the front plate
of the case 3. Thus, the opening valve 523 provided to the water
supply pipe 51 is opened by operation of the opening switch 534 so
that the water is injected into the chamber pot 21 through the
water supply pipe 51.
[0048] Then, after a certain time, the closing switch 525 provided
to the side of the bed 1 is manipulated to intercept water
introduced into the chamber pot 21, which completing the washing
work for the chamber pot 21. This gives a bed for a patient that
may be more easily manipulated.
INDUSTRIAL APPLICABILITY
[0049] As described above, the bed for a patient according to the
present invention may minimize production costs by simplifying
configurations of the drainage means and the cover means of the
chamber pot.
[0050] In addition, since water may be injected into the chamber
pot without any manipulation after relieving nature, the bed for a
patient of the present invention may be used in a more convenient
way.
[0051] The present invention has been described based on preferred
embodiments with reference to the accompanying drawings, but it is
obvious that various modifications may be made by those skilled in
the art without departing from the scope of the present invention.
Therefore, the scope of the invention should be understood by the
appended claims including such various modifications.
