Description

Technical Field

[0001] The utility model belongs to a device for preventing bedsores or helping patients turn over, such as the technical field of special mattresses for this purpose, and specifically relates to an inflating device for a prone position bedsore-preventing air mattress. Background Art

[0002] Prone ventilation refers to the use of a turning bed, a turning device or manual operation to allow the patient to undergo mechanical ventilation in the prone position, thereby improving oxygenation. When the patient is turned from the supine position to the prone position, the prone ventilation treatment mode has many pipelines and monitoring indicators, and the nursing difficulty coefficient increases. In order to turn the patient over, a large amount of manpower is required to turn the patient over during the clinical operation. Most of the prone ventilation mattresses currently used in medical work are equipped with pads at corresponding positions to pad the corresponding positions on the cushions to reduce pressure events. The positions must be aligned in advance, and the cleanliness of the bed surface cannot be guaranteed. The corresponding patient needs to turn over to achieve the discomfort of the human body maintaining a posture for a long time. A utility model is needed to solve this problem, so that the placement of nursing equipment will not affect the cleanliness of the patient's bed surface, the patient's bony protrusions will not be under pressure for a long time, and the pressure situation can be adjusted to reduce the occurrence of pressure sores.

[0003] The Chinese patent number is 201921002706.6, which discloses a prone position ventilation mattress, including: a support base plate, a support pad and a plurality of support air bags, the support pad is laid flat on the support base plate, a plurality of support air bags are arranged on the support pad, a facial through hole and a pipe through groove 1 connected to the facial through hole are arranged at the front end of the support pad, and a perineum through hole and a pipe through groove 2 connected to the perineum through hole are arranged in the middle of the support pad. By arranging a support airbag on the support base plate, the inflation of the airbag makes the human body rise when the human body is in the prone position, and the deflation of the airbag makes the human body fall, thereby preventing a part from being compressed for a long time and reducing bedsores; by using the support base plate, the support pad and multiple support airbags, the pressure on the head is reduced through the face through holes and the perineum through holes when the patient is in the prone position. Pressure sores are easily caused by a long time, and the perineum is easily compressed. The stacking of air ducts is solved by the pipe grooves 1 and 2. The inflation and deflation of multiple support airbags lift and lower the patient corresponding to the time the support pad is compressed to improve the pressure sore events caused by the patient being compressed for a long time. When inflating, the structure needs to use the method of simultaneously inflating and deflating the chest and abdominal airbags and the leg airbags. During use, it is difficult for patients with larger bodies to adjust to a suitable prone position. How to control the chest and abdominal airbags or the leg airbags to inflate and deflate them respectively makes the prone anti-bedsore air mattress have a wider range of applications and is easier to operate, which needs to be studied.
