Abstract
A modular long-term patient care mattress designed to assist health care workers in effectively treating patients with bedsores or severe burns. The mattress system is made up of identical interlocking sections, which are designed to allow conditioned air to be blown through their internal structure to contact the patient's body. The modular sections, when fitted together, are designed to be placed on top of any standard hospital bed and flex in consort with the bed adjustment system. The entire apparatus is designed to be dismantled and cleaned in existing hospital washing facilities. The airflow supply is provided by its own heating and cooling system, which also includes a germicidal UV light to sanitize the airflow prior to being blown towards the mattress and patient.
Description
MODULAR LONG-TERM PATIENT CARE MATTRESS
This invention provides an improved long-term patient care mattress to aid in the prevention and cure of bedsores, and assist in the care of burn victims.
BACKGROUND OF THE INVENTION
There have been many attempts at producing a bed or mattress designed to alleviate or prevent the occurrence of bedsores in long-term care patients. The main problem with bedsores has been through the lack of circulation of blood vessels at the skin surface where there are pressure points. Coupled with the hot moist clammy conditions that allow a bacterial growth to take place.
This develops into a zone of ever increasing dead tissue which progresses to deeper and deeper tissue layers and eventually to the bone itself.
Some of the previous attempts at producing a viable invention to deal with this problem are:
Cited documents: CA2188811 YAMADA
There are common difficulties attributed to all of these inventions that have kept them from going into full production and benefiting long-term care patients. These difficulties are solved by this current application.
SUMMARY OF THE INVENTION
This invention is of a modular long-term patient care mattress designed to assist health care workers in the prevention and cure of bedsores as well as to assist in the comfort and treatments of burn victims. The modular system is designed to be placed on top of any standard hospital patient care bed. The mattress is constructed with a built in hinge on every sectional pad that allows the assembled mattress to flex as needed to accommodate the contour adjustments of an automatic or semi-automatic hospital bed. All the internal and external components within each sectional pad can be easily disassembled and placed in any current hospital washing machine facilities for sanitization. Additionally, should one or more sections become soiled, they can easily be replaced without lifting the patient off of the bed by replacing only one section at a time. The silicon gel surface pad, which is perforated through with at least 3/8" diameter holes has extreme flexibility to reduce skin abrasion of the patient who is lying on the mattress. The airflow can be controlled in many ways for the comfort of the patient. It can be heated or cooled with its own dedicated air conditioning unit. The air can also be filtered and sanitized with the addition of the germicidal unit attached to the air intake side of the air conditioning unit.
Additionally, since each pad has its own air control valve, each section can deliver a controlled amount of conditioned air with the addition of another single airflow line.
Both the heating unit and the refrigeration unit on the air conditioning apparatus can be used at the same time. As an example, the top %2 of the bed may require cool air to deal with bedsores, where as the bottom %2 of the bed could be kept warm so the patient does not become chilled. Also built into each section airflow line, just below elbow B-3, is a threaded male end with its own dedicated control SUMMARY OF THE INVENTION (continued) valve. This attachment is designed to facilitate the addition of medicated vapor or mist to the sectional pad. This would be useful in concentrating the medical treatment to a specific portion of the patient's body, while the other pad sections simply supply a warm dry air.
The uses of this modular long-term patient care mattress are not restricted to only long-term care patients. The need to slowly raise the body temperature or hypothermic patients can be readily accomplished by placing them on a modular mattress and warming the entire body by slowly increasing the warm air applied to the patient. Additionally patients who are suffering from dangerously high body temperature could be treated by supplying very cold air to sections of the body without the need to immerse them in ice water or surround them with ice packs or additional oral medication. By submersing the remote heat dissipating coil rack in cold water, it dramatically increases the efficiency of the refrigeration unit. By blowing temperature controlled cold air on all or some parts of the body it is less traumatic for the patient than either ice packs or cold-water immersion and is less stressful on the patient's heart.
DETAILED DESCRIPTION OF THE INVENTION
The modular long-term patient care mattress is described in three primary sections. The parts of the interlocking pads that form the mattress are indicated with an "A". The parts of the airflow apparatus are indicated with a "B". The heating and cooling air conditioning unit is indicated with a "C".
