Description

Technical Field

[0001] This invention relates to the field of medical care equipment technology, specifically to a water-heated, temperature-controlled, anti-bedsore alternating air mattress and its intelligent constant temperature control method. Background Technology

[0002] Patients who are bedridden for extended periods are highly susceptible to pressure sores (bedsores) due to prolonged pressure on local tissues and poor blood circulation. These sores are accompanied by pain and infection risks, severely impacting the recovery process. Traditional anti-bedsore mattresses have significant technical shortcomings:

[0003] Single function, relying solely on air pressure for decompression: lacking temperature regulation, it is cold in winter and hot in summer, and the skin is prone to sweating and dampness, which increases the risk of pressure sores;

[0004] Temperature control and air pressure are separated, resulting in poor coordination: Ordinary water-heated pads do not have alternating pressure reduction, and air-inflated pads do not have constant temperature function, making it impossible to balance pressure reduction and comfort.

[0005] The temperature control is crude and inaccurate: there is no closed-loop temperature control, the water temperature fluctuates greatly, and excessively cold or hot water can easily cause discomfort or scalding.

[0006] Inadequate air / water circuit design: uneven water circulation, asynchronous airbag inflation, localized overcooling / overheating, and uneven decompression;

[0007] Inadequate safety protection: lack of overheat, water shortage, and leakage protection, resulting in insufficient safety in medical settings;

[0008] The control logic is simple and the intelligence is low: it cannot adjust the air pressure and temperature in a coordinated manner, and cannot adapt to the needs of different body types and medical conditions. Therefore, a water-heated temperature-controlled anti-bedsore alternating air mattress and its intelligent constant temperature control method are proposed. Summary of the Invention

[0009] In view of this, the present invention provides a water-heated temperature-controlled anti-bedsore alternating air mattress and its intelligent constant temperature control method to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0010] The technical solution of this invention is implemented as follows: A water-heated, temperature-controlled, anti-decubitus alternating air mattress includes a water-heating pipe and a control box. Multiple air bladders are located at the top of the water-heating pipe. A temperature-controlled water tank is installed on the inner bottom wall of the control box. A water pump is installed on the inner bottom wall of the control box. The water outlet of the air outlet pipe is connected to the temperature-controlled water tank. The water inlet of the air outlet pipe is connected to the water outlet of the water pump. The water inlet of the water pump is connected to the temperature-controlled water tank.

An air inlet pipe is connected to the outer wall of the shunt pipe. An air pump is installed on the inner bottom wall of the control box. One end of the air inlet pipe is connected to the air outlet of the air pump.
