Abstract

The invention relates to a coil-type alternating automatic inflation and deflation high polymer material gel pad. A high polymer material gel tube A and a high polymer material gel tube B are arranged in an outer frame of the high polymer material gel pad, the tube A and the tube B are coiled in parallel to form a coil-type disc-shaped plane, and the tube A and the tube B can alternately and automatically inflate and deflate. The raw materials for preparing the tube A and the tube B and a preparation process also improve physical and chemical properties of the formed gel pad. The formed gel pad has a fast elasticity recovery, and is green and environment-friendly, and has a suitable comfort when being in contact with the skin. The high polymer material gel pad can assist a nurse in regularly decompressing a pressed skin of a patient, prevent pressure sores and improve nursing quality. The coil-type alternating automatic inflation and deflation high polymer material gel pad can effectively help nurses or relatives to prevent pressure sores of patients, pressure reduction of the pressed skin is not needed when the patients have a rest, sleep quality of the patients is improved, and nursing workload is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mosquito-repellent incense type alternately automatically inflatable and deflated polymer material gel pad and the gel tube used. Background technique [0002] In the prior art, for bedridden patients who need to lie on their back for a long time or long-term bedridden patients after surgery, nurses are required to decompress the compressed skin of the patients on a regular basis. In the process of decompressing the compressed skin of the patient, it may affect the doctor's operation, and may also affect the effect of skin decompression due to the limited range of operation. Failure to decompress the patient's skin on time due to an interruption in the procedure increases the patient's risk of developing a pressure ulcer. In particular, the patient's coccyx is at greater risk of developing pressure sores. [0003] CN106924002A relates to a new type of gel position pad...
