Pressure bandage based on film pressure sensor

Abstract

A pressure bandage based on a film pressure sensor comprises a bandage layer and a sensor layer. The bandage layer is fixedly connected with the sensor layer. The sensor layer comprises the film pressure sensor, a resistance-voltage conversion module, a voltage-pressure fitting module and a wireless module. The film pressure sensor is sequentially connected with the resistance-voltage conversion module, the voltage-pressure fitting module and the wireless module. The resistance-voltage conversion module, the voltage-pressure fitting module and the wireless module are integrated on a circuit board at one end of the sensor layer. The wireless module is wirelessly connected with an external display device. The pressure bandage has the advantages that the structural design is reasonable, pressure conditions of bandages during use are converted into image information that is output to a screen, and the pressure is monitored in real time; different conductor patterns can be designed according to different application scenes of the bandages, and key monitoring of a specific part is realized.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a pressure bandage based on a thin film pressure sensor. Background technique [0002] The pressure of the bandage on the injured part has a significant effect on softening the scar, preventing scar hyperplasia, and lightening the color, and the therapeutic effect is related to whether the patient continues to use pressure therapy. If the pressure of the bandage is too small, it will not achieve the effect of pressure therapy, and if the pressure is too high, it will affect blood circulation. And at present, the degree of tightness of the bandage around the injured part often depends on the experience of the medical staff, and the degree of bandage cannot be quantified. Contents of the invention [0003] In order to solve the above problems, the present invention provides a pressure bandage based on a thin-film pressure sensor. The thin-film pressure sensor is used as a sensing...
