In order to facilitate understanding, the working principle of the pressure management device for preventing pressure sores in medical operations and postoperative rehabilitation periods of the present invention is explained.

Use the utility model discloses an in medical treatment operation and postoperative rehabilitation phase prevention pressure management device who presses sore prevents to press the management process that sore took place to the patient, at first will need to carry out the patient of operation or postoperative rehabilitation phase management to prevent the utility model discloses a device is last, and patient's body contacts with the gasbag to the realization is to the function of bearing of patient's health. When the patient is in a static state or a state close to the static state, the pressure conditions of all parts of the body of the patient contacted with the air sac are different, and when the local pressure is overhigh, blood circulation disturbance caused by long-time pressure of local tissues, and soft tissue pressure sore caused by local continuous ischemia, hypoxia and malnutrition occur. Therefore, it is necessary to adjust for the local overpressure so that the pressure at the portion of the patient's body in contact with the bladder is in a reasonable range to prevent the occurrence of pressure sores. When the pressure of the part of the patient body in contact with a certain air bag is too high, the body of the patient will generate too high pressure to the air inside the air bag. At the moment, the gas pressure in the air bag is communicated with the alarm device connected with the air bag, the pressure sensor obtains the real-time pressure value of the gas in the air bag through detecting the gas pressure in the air bag, when the pressure value exceeds a set range, the air bag is decompressed through the check valve arranged on the alarm device, and when the pressure in the air bag is reduced to a specified range, the check valve is closed, so that the pressure in the air bag is kept in a preset threshold range. The device of the utility model can realize the support of different parts of the patient by arranging a plurality of groups of mutually independent arranged air bag structures, when the local pressure of the contact part of the patient and the air bag exceeds a certain pressure, if the patient is in the state for a long time, the possibility of pressure sore induced by the pressure sore is increased, and the monitoring of the local air bag pressure and the adjustment of the pressure can be realized by the independently controlled alarm device, so that the pressure between the patient and the air bag is controlled within a preset range; the utility model discloses can not independently stand up to current disease, need many medical personnel to stand up and change the prone position, but the operation process is wasted time and energy, and the work nursing volume is big, stands up untimely scheduling problem, turns over the board structure through setting up to overturn and stands up the patient with supplementary medical personnel, has improved the work efficiency and the convenience of clinical care work greatly.

It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
