Bruising-resistance variable-temperature blanket

Abstract

The invention discloses an anti-pressure injury temperature-changing blanket, which belongs to the technical field of medical devices. The anti-pressure injury temperature-changing blanket includes: an outer bag, a first inflation tube, a second inflation tube, an inflation device, a time difference control device, a temperature control device and an inflation device; the first inflation tube and the second inflation tube are both arranged in the outer bag Inside, the inflation device is used to inflate and deflate the first inflation tube and the second inflation tube; the temperature control device is used to control the temperature of the gas in the inflation device; the time difference control device is used to control the inflation device for the first inflation The tube and the second inflation tube are inflated and deflated. The invention realizes the differential inflation and deflation of the first inflatable tube and the second inflatable tube, realizes the differential sequence undulation of different parts of the anti-pressure injury temperature-changing blanket, so that the temperature-changing gas can be transmitted to various parts of the body through the gap between the inflatable tubes , which improves the temperature control effect on the patient, and also prevents damage caused by squeezing a certain part of the patient for a long time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a crush-proof temperature-changing blanket. Background technique [0002] Body temperature is one of the basic vital signs of the human body. Hypothermia is one of the common complications in clinical surgical anesthesia. Its occurrence often causes serious damage to patients, such as shivering, increased oxygen consumption of the body, increased cardiovascular and cerebrovascular complications, and increased lactic acid after surgery, which also brings serious damage to patients. discomfort. Conversely, high fever can also cause serious complications to patients. At the same time, complex or major operations often take a long time and the body position cannot be changed. The body is subjected to its own gravity or the pressure of other objects for a long time to cause ischemic necrosis, resulting in serious complications such as crushing of non-operative parts, hypothe...

Conversely, high fever can also cause serious complications to patients

At the same time, complex or major operations often take a long time and the body position cannot be changed. The body is subjected to its own gravity or the pressure of other objects for a long time to cause ischemic necrosis, resulting in serious complications such as crushing of non-operative parts, hypothermia, and high fever. symptoms, thereby increasing the patient's hospital stay and medical costs

[0003] At present, the traditional temperature-changing blanket can only cover the radiation to control the temperature, and cannot prevent the patient from being crushed; at the same time, the traditional temperature-changing blanket cannot achieve the effect of controlling the temperature because it is pressed under the patient's body and cannot be inflated. The disinfection effect of the heating blanket is limited, and the gas filled with the controlled temperature cannot pass through the patient's back, shoulders, buttocks, and lower limbs, and the effect of the variable temperature blanket is limited.

On the other hand, although variable temperature water blankets or conduction heating pads can provide a good temperature for the patient's back, they may cause serious pressure to the patient under the action of their own gravity or external pressure due to the long-term major surgery because the body position remains unchanged. hurt
