Definitions
- the present invention relates generally to patient supports and, more particularly, to fluid-filled patient supports for supporting the body of a person.
- the present invention further relates to a method of providing disposable patient supports.
- Beds including mattresses, mattress overlays, mattress toppers, and mattress replacement systems having a plurality of air bladders or sacs to provide an adjustable patient support surface are well known in the art.
- One type of inflatable patient support surface is a "low air loss" mattress which is in communication with a blower and includes a plurality of microvents configured to slowly release air.
- Examples of conventional inflatable patient supports are disclosed in U.S. Patent Nos. 4,949,413 to Goodwin and 5,647,079 to Hakamiun et al., which are assigned to the assignee of the present invention and the disclosures of which are expressly incorporated by reference herein.
- inflatable patient supports are reusable. More particularly, such patient supports typically include a wipable outer surface that is cleaned after each patient use so that it is sanitized for its use by the next patient. Often such patient supports are rented by hospitals wherein after each patient use, the supplier must physically remove the patient support and have it cleaned and sanitized for future use.

- Fig. 16 is a block diagram illustrating a method of mattress distribution and disposal in accordance with an illustrative embodiment of the present invention. The illustrated method eliminates the need for service technicians from the mattress supplier to install, and then subsequently remove and clean, a conventional mattress from a hospital or care facility 410. Moreover, the prior art method typically requires that a service technician remove the mattress from the hospital after use by a single patient.
- the mattress 10 or patient support is initially stored at a distribution center 420.
- a fluid supply 38 is stored at the hospital 410 and may be owned or rented by the hospital 410.

- the hospital 410 contacts a sales office 430.
- Such communication with the sales office 430 may be through conventional means, such as telephone, electronic mail or conventional mail.
- the sales office 430 Upon receiving an order for a mattress 10, the sales office 430 processes the order and sends a request to the distribution center 420. In turn, the distribution center 420 sends the mattress 10 to the hospital 410, again through conventional channels such as conventional mail. Illustratively, the mattress 10 is shipped in a sterile condition and is contained within sealed packaging to maintain its sterile condition.
- the hospital 410 Upon receiving the mattress 10, the hospital 410 unpacks the mattress 10 from the packaging and places the mattress 10 on a support surface, such as the frame of a hospital bed. Next, the hospital bed 410 couples the mattress to the fluid supply 38. Fluid is then supplied to the mattress 10 from the fluid supply 38 thereby inflating the plurality of bladders 50. During operation, a patient is supported on the upper surface 26 of the mattress 10. As detailed above, the fluid supply 38 illustratively controls selected zones of the bladders 50 independently such that different fluid zones are provided with different pressures. Once treatment of the patient has been completed, and the mattress 10 is no longer required, the mattress 10 is deflated and the fluid supply 38 uncoupled therefrom. The mattress 10 is then replaced with a substantially identical second mattress for providing support to a different patient. Next, the hospital properly packages and ships the mattress 10 to a certified disposal facility
- the disposal facility 440 then disposes of the mattress in a proper manner.
- the mattress 10 is incinerated at the disposal facility 440.
