BATHING APPARATUS

Abstract

Improved bathing apparatus and their conformations. The improved bathing apparatus includes descriptions of efficient methods used in bathing bedridden persons without the need to move them from the bed. The process will include devices used in collection of body waste generated by bedridden individuals. Since cleanliness of bedridden individuals is paramount to continuing health as well as prevention of new infections, the devices are converted to a secondary use for bathing since a conduit can also be used for drainage of wastewater from showering or bathing. An impermeable layer with a spout leading into the conduit is placed under the patient. The wastewater generated can be collected for disposal or directed to a drainage system. Several iterations of the bath system are described, presenting a choice for the user depending on conformations of and attachments to the bed. In all conformations, the drainage outlet can be stoppered to generate a pool of water when needed.

DETAILED DESCRIPTION OF THE INVENTION

[0034] The following description should be read with reference to the drawings, in which like elements in different drawings are identically identified and preceded by the page number. The drawings which are not to scale depict our interpretation of a concept and are not intended to limit the scope of the invention. The description illustrates by way of example the principles of the invention. The description will clearly allow one skilled in the art to make and use the invention. The variations shown represent adaptations of the initial design concept which significantly simplify the equipment necessary to permit in-place bathing and demand less time and effort of the caregiver in carrying out their duties.

[0035] The waste system as described in priority publications is represented in FIG. 1A and FIG. 1B. The device shown in FIG. 1B has 3 sections: a support section inserted through the mattress serving as a conduit (132), a flexible section allowing position change for the collection apparatus (128), and a specialized collection unit (110). It is incorporated as into a bed shown in FIG. 1A. The simplicity of design is intentional since the ease of removal, cleanup and reinstallation is a hallmark of the invention. The intent is a significant decrease in the use of adult diapers while providing an improved method of collecting body waste. The device will also be useful in allowing a patient to be showered or bathed in bed without significant lifting of the patient. The most significant advantage to the caregiver is time saving, followed by the prevention of injury to both caregiver and patient from accidents.

[0036] In this application, we will focus on the innovations which will allow for bathing the individual in bed. The conduit for waste material (132) is inserted in the bed. The material of choice for the conduit is currently PVC piping normally used in plumbing fixtures. Alternatives are also being considered. The bed surface (142) is protected by a fitted impermeable cover (409) which protects the mattress and has a spout leading into the waste conduit (432). Above the bed protection layer, is a comfort layer (411) which has the requirement of wicking away moisture from the skin and can be easily removed or changed. The patient's buttocks will rest on this layer. The conduit for waste removal is also helpful in allowing some drainage. The conduit (432) leads to a flexible section (428) which has two functions: it leads to a specialized collector (110) which can be moved to a desired position, either under a bed or moved when a sample of the contents must be taken, or cleaning of the unit is necessary.

[0037] The focus of the rest of this description will be on the various iterations of the bathing devices. The use of a bath sheet (201,301) made of impermeable flexible fabric and having a spout (203, 303) which is directed into the conduit (232, 332, 432) is a simple solution. It is first placed under the patient as bed linen is removed. The mattress protector (409) can remain in place, but the bath sheet (201,301) can be used alone. The method of placing the patient on their side while changing bed linen, will also be used to position the bath sheet under the patient with the spout inserted into the conduit. It is necessary to elevate the head of the bed to a comfortable position, and the sheet is draped over side rails, foot rails or other supports as previously described. The draping of the sheet over these supports forms an enclosure, FIG. 5B. A list of supports for bath sheets and other types of enclosures is provided in Section above. An extended showerhead provides the source of water for a shower. If a bath is required, a stopper (202, 302) can block the flow of water through the conduit.

[0038] The sides of the bath sheet can be gathered as shown in FIG. 5A and FIG. 5B. prior to draping over the supports. This will prevent sagging and accidental spillage of water. Supports which can be designed into a bed where none exist are shown in FIG. 6A and FIG. 6B. These extensions can be built into the corners of beds as shown; they can be elevated when needed then returned to a normal position at the completion of the bath or shower.

[0039] A second form of enclosure can be developed when a fitted mattress protector which has a spout leading into the conduit as shown in FIG. 7A (partial view) and FIG. 7B, is further modified by the addition of a layer of the same impermeable material which drapes as shown in FIG. 7C. The draped portion can be tucked beneath the mattress when not in use. When a bath is needed, linen is simply removed from the bed, the draped section is lifted and placed over supports as previously described, forming an enclosure shown in FIG. 8. Once the bath has been completed, the surface is wiped and dried, reverting to the role of mattress protector. The bed can then be made up as normally required.

[0040] A third form of enclosure is envisioned when the conduit, bed cover and sides of the enclosure (1012) are formed from a single unit. This is shown in FIG. 10. This form is the most adaptable since the conduit can more easily be modified at the manufacturing stage to fit any thickness of mattress. Beds which are normally leased for the homecare market have mattresses which are thinner, and at the lower range of quality. All grades of bedding are adaptable to the incorporation of the innovations described, but we are currently focused on the homecare market. Consultations with polymer scientists, engineers and manufacturers are ongoing to generate working models of the prototypes. To generate the bed protector layer, the polymer can be extruded to form a thin flexible bed cover. The conduit can be prepared by a different method such as injection polymerization with parameters such as firmness and inflexibility which will allow placement within the mattress, in the place of PVC piping normally used. This method of preparation will allow for customization of the conduit based on the depth of the mattress; when merged with the bed cover section, a single item is formed which is easy to handle, as well as being easily cleaned and maintained. This confirmation will require unique methods of merging with the flexible region (128) different from earlier versions. Research is ongoing on possible new materials to be used so that performance of the unit as a waste collector is not impaired.

[0041] In all conformations, it is necessary that the flow of water or waste is not impeded when the flexible connector is angled or removed from a straight drop position directly under a bed. If a kink is formed in the flexible region, the flow of material can be stopped or slowed. We have identified connectors which will solve this problem. Connections to disposal units within a home sewer or wastewater system for non-infections body waste or wastewater is a desired step. Research in consultation with master plumbers to identify necessary accessories for this action is ongoing.

INDUSTRIAL APPLICABILITY

[0042] The innovations described in this application apply to the healthcare industry, particularly to the care of individuals who are bedridden or unable to care for themselves. They are intended to help caregivers by demanding less time and effort as well as to improve the level of care provided to individuals cared for at home.
