Abstract

An apparatus and method for managing waste from patient care, maintenance, and/or treatment includes an inflatable bladder member disposed to support at least a first portion of the body of the patient. A flexible basin member is fitted over the bladder and receives waste materials, and a filter sheet is disposed atop the basin member. The basin member is connected to a liquid/gas separator and a vacuum blower. A liquid waste pump is connected to the separator to transfer liquid waste to a holding jug. A vacuum wand provides both suction and rinsing liquid via an on-demand pumping supply configuration that enables the rinsing liquid supplied from a rinse jug to be heated. Liquid levels in the rinse liquid jug, the holding jug, and the separator'"'"'s holding reservoir are sensed by capacitive level sensing devices which supply signals to a microprocessor which controls various functions of the apparatus. Special inflatable sacks are provided to assist turning the patient to facilitate cleansing of the patient. Inflatable cushions receive the inflatable bladder member and dispose it to become coextensive with the support of the rest of the patient in a patient support apparatus, if desired.

Claims

1. An apparatus for managing waste arising from at least one of the care, maintenance, and treatment of a patient, the apparatus comprising:

a) means for supporting at least a portion of the patient'"'"'s body, said supporting means including a flexible member inflatable with pressurized air, said flexible member including a plurality of flexible surfaces forming in combination a discontinuous surface for receiving said portion of the patient'"'"'s body;

b) a means for catching waste, said waste catching means being carried by said supporting means;

c) a vacuum blower disposed for sucking the wastes from said catching means; and

d) a holding reservoir disposed in communication with said catching means and said vacuum blower to receive the waste sucked from said catching means by said vacuum blower.

2. An apparatus as in claim 1, wherein:

a) said supporting means includes;

i) a support member configured to contain pressurized air,

ii) said support member defining a plurality of discrete support fingers disposed adjacent to each other and separated from each other, and

iii) each said support finger having a free end defining a patient support surface, said patient support surfaces being disposed to support the weight of said portion of the patient'"'"'s body.

3. An apparatus as in claim 1, wherein:

e) said catching means includes;

i) a liquid impermeable basin member,

ii) said basin member being configured to conform to and receive said supporting means,

iii) said basin member being further configured with a floor disposed beneath the upward-most level of said supporting means when said basin member is fitted over said supporting means and receives said supporting means,

iv) said basin member being further configured with at least one drain opening defined through said floor, and

v) said floor being configured so as to slope toward said at least one drain opening.

4. An apparatus as in claim 3, wherein:

f) said catching means further includes;

vi) a liquid permeable filter sheet disposed to be carried atop said basin member.

5. An apparatus as in claim 4, further comprising:

vii) means for selectively, detachably securing said filter sheet against movement away from a position resting over said basin member.

6. An apparatus as in claim 1, further comprising:

e) means for collecting the waste received by said holding reservoir, said collecting means being removably securable in communication with said holding reservoir.

7. An apparatus as in claim 6, wherein:

said collecting means includes a waste collection container, and a waste transfer pump connected in communication with said waste collection container and said holding reservoir.

8. An apparatus as in claim 7, further comprising:

means for detecting a predetermined level of liquid waste inside said waste collection container, said liquid level detecting means being disposed in communication with said waste collection container.

9. An apparatus as in claim 1, further comprising:

e) means for cleansing, said cleansing means being connected in communication with said holding reservoir.

10. An apparatus as in claim 1, further comprising:

e) means for cleansing said catching means, said cleansing means including a rinse solution container, a rinse solution nozzle, and a rinse solution pump connected in communication with said rinse solution container and said rinse solution nozzle.

11. An apparatus as in claim 10, further comprising:

means for detecting a predetermined level of liquid rinse solution inside said rinse solution container, said liquid level detecting means being disposed in communication with said rinse solution container.

12. An apparatus as in claim 1, further comprising:

e) means for detecting and signaling the presence of liquid waste, said detecting and signaling means being disposed downstream of said catching means; and

g) means for controlling operation of said vacuum blower responsive to moisture detection by said detecting and signaling means, said control means being connected in communication with said vacuum blower and to said detecting and signaling means.
