System for collecting body waste of non-ambulatory patients

Abstract

A body waste collection system for bedridden or chair-bound patients. A waste entry port may interface with a resting surface of the bed or chair by way of a funnel that terminates at the resting surface. A collection unit may be fluidly coupled to the waste entry port by a flexible conduit system. The collection unit may include a temperature gauge, a volume measure, a sample port, and an odor removal port. Once the bedridden or chair-bound patient has assumed a release position along the resting surface defined by the waste entry port, no other lifting or movement of the patient is needed to collect their body waste in the collection unit, which can utilize the integrated hardware.

DETAILED DESCRIPTION OF THE INVENTION

(12) The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

(13) Broadly, an embodiment of the present invention provides a body waste collection system for bedridden or chair-bound patients. A waste entry port may interface with a resting surface of the bed or chair by way of a funnel that terminates at the resting surface. A collection unit may be fluidly coupled to the waste entry port by a flexible conduit system. The collection unit may include a temperature gauge, a volume measure, a sample port, and an air displacement port. Once the bedridden or chair-bound patient has assumed a release position along the resting surface defined by the waste entry port, no other lifting or movement of the patient is needed to collect their body waste in the collection unit, which can utilize the integrated hardware. At this point, samples of the waste can be removed via the sample port, or the entire collection unit can be removed by disengaging from the flexible unit. Reagents can be added directly to the container in order to give a desired reaction product to aid in analysis of the waste. The researcher is spared physical contact and possible infection from the waste. The waste is spared further contamination by being transferred to other containers.

(14) The container gives visual information such as color, quantity, temperature, physical form [fluid or solid] which may be important to a caregiver. Flow rates can be easily calculated. The presence of sensors in the container may provide information which is transmitted electronically to a remote location or device. These are all parameters which assist in analyzing the state of health of a patient.

(15) Referring now to FIGS. 1 through 11, the present invention may include a waste collection unit 10 that is fluidly connectable, by way of a flexible conduit system 28, 60, 70, to a waste entry port 34 or 58 in a resting surface, such as along a seat 68 of a chair 66 or the mattress 38 or 52 of a bed 62.

(16) In certain embodiments, the flexible conduit system 60 may be oriented at transverse directions relative to the solid unit 56. A funnel 30 or 54 may extend upwardly from the waste entry port 34 or 58. A distal end of the funnel 30 or 54 may interface with the resting surface at a drain opening 44. The drain opening 44 may include an opening in a mattress 38, 52 and bed sheet 42 of the bed 62 or the seat 68 of the chair 66. In certain embodiments, the drain opening 44 could be a tubular element that is inserted into a rigid pipe 32. In other embodiments, the drain opening 44 could be a circular reinforcing, such as defining an opening in the bedsheet 42. Said interface may define a release position for anatomy of a patient discharging the body waste of fecal matter or urine. The waste entry port 34 or 58 may be closed off by a plug 36.

(17) In other embodiments, the flexible conduit system may be 60 oriented at transverse directions relative to the rigid pipe 56. A funnel 30 or 54 may extend upwardly from the waste entry port 34 or 58. A distal end of the funnel 30 or 54 may interface with the resting surface or protrude slightly above or below the resting surface. The rigid pipe 32 may interconnect the flexible conduit system and the waste entry port 34 or 58 (in other words, the pipe 32 may be considered the solid portion of an overall conduit system). The rigid pipe 32 may extend entirely through the mattress 38 or 52; additionally, the rigid pipe 32 may also protrude through at least a portion below the frame 40. In certain embodiments, if a smaller patient is on the mattress 38 or 52, the rigid pipe 32 hardly moves; though, if a heavier patient has their mass bearing on the rigid pipe 32, it drops down more, and so the mattress 38 or 52 may squish, but the rigid pipe 32 just juts out more and remains solid. Since the rigid pipe 32 connects to the flexible conduit system (in FIG. 5, #28), no harm is done to the present invention because flexible conduit 28 would just bend under the force of the patient. When the patient gets up, the mattress 38 or 52 expands and the rigid pipe 32 moves back up.

(18) The resting surface may be associate with a drain opening 44, which may be an opening in a mattress 38, 52 and bed sheet 42 of the bed 62 or the seat 68 of the chair 66. The above-mentioned interface may define a release position for anatomy of a patient discharging the body waste of fecal matter or urine. The waste entry port 34 or 58 may be closed off by a plug 36.

(19) In certain embodiments, the impermeable bedsheet 42 on the mattress 38, 52—having its own drain opening 44 to interface with the funnel 30 and thus the waste entry port 34 or 58—can be utilized as a makeshift funnel through lifting up the edges thereof, as illustrated in FIG. 8. In this embodiment, a water source 48 may be used to clean the impermeable bedsheet 42 and flush residual body waste down the waste entry port 24 by way of a flow 50.

(20) The collection unit 10 has as its main opening the flange 14 coupling to the flexible conduit 28 or 70. The volume enclosed by the collection unit 10 is defined by sidewalls. The sidewalls may include a temperature gauge 16 and a volume measure 18. The sidewalls may also provide a sample port 20 with a sample port cap 22 for sealing the sample port 20. The sidewall may also house an air removal port 24.

(21) In certain embodiments, the collection unit 10 can be removed and a sewer conduit 46 may fluidly connect to the flexible conduit 28.

(22) In certain embodiments, a support pillow 64 may facilitate the patient assuming or being guided to the release position, similar to an adjustable hospital bed being moved to likewise assist the patient in assuming the release position. This would also occur when a normal bed is equipped with a portable version of the invention.

(23) A method of using the present invention may include the following. The collection unit 10 disclosed above may be provided. The collection unit 10 may be fluidly coupled to the flexible conduit system 28, and 60, which in turn is fluidly connected to the waste entry port 34 or 58. The patient may be positioned over the drain opening 44 of the overall system disclosed above—at the release position. There the patient can release body waste without having to be moved off their bed or chair.

(24) The collection unit 10 may be removed and the waste diverted to a sewer system—the flexible unit 28 is linked to the sewer line—when the waste is not infectious. The person can be cleaned by paper which is then flushed or a bidet-style cleaning by shower is possible. In certain embodiments, the flexible conduit system can be connected to the home waste-water system when substantial quantities of water are to be removed.

(25) Additionally, the present invention can be made portable, allowing its use in transport vehicles. A portable unit can also be used at home if a bed should not be modified. This is shown in FIG. 10. The system can also be retrofitted onto wheelchairs per FIG. 11.

(26) It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
