Embodiment 1

[0026] A pressure sensor with a gas-permeable function, including a bottom conductive film 1, a top conductive film 2 and an intermediate layer isolation film 3, wherein, such as figure 1 As shown, a negative electrode lead 11 and a plurality of negative electrode conductive lines 12 are printed on the bottom conductive film 1, and all the negative electrode conductive lines 12 are output through the negative electrode lead 11 after converging, and the negative electrode conductive lines 12 are evenly distributed on the bottom conductive film 1, It can be printed horizontally or vertically. In order to ensure the sensitivity of the pressure sensor, the negative conductive lines 12 are generally denser, and the distance between two adjacent negative conductive lines 12 is generally about 4 mm. The bottom conductive film 1 is not a negative conductive line. A plurality of ventilation holes 13 are arranged in the area, and the diameter of the ventilation holes 13 is 0.5 mm, which ...

Embodiment 2

[0031] The pressure sensor with pressure position recognition function described in this embodiment includes a bottom conductive film 1, a top conductive film 2 and an intermediate isolation film 3, wherein the structure of the intermediate isolation film 3 is basically the same as that in Embodiment 1, The main difference is the bottom conductive film 1 and the top conductive film 2. Such as Figure 4 As shown, a negative electrode lead 11 and a plurality of negative electrode conductive lines 12 are printed on the bottom conductive film 1, and all the negative electrode conductive lines 12 are output through the negative electrode lead 11 after converging, and the negative electrode conductive lines 12 are evenly distributed on the bottom conductive film 1, It can be printed horizontally or vertically. In order to ensure the sensitivity of the pressure sensor, the negative conductive lines 12 are generally denser, and the distance between two adjacent negative conductive lin...

Abstract

The invention discloses a pressure sensor with the ventilation function. The pressure sensor comprises a bottom layer conducting film, a top layer conducting film and a middle layer isolation film, wherein a negative electrode lead and a plurality of negative electrode electric leads are printed on the bottom layer conducting film, at least two positive electrode conducting areas are arranged on the top layer conducting film, each positive electrode conducting area is connected with one positive electrode lead, a plurality of positive electrode electric leads are printed inside the positive electrode conducting areas, the multiple positive electrode electric leads in the same positive electrode conducting area are output through the corresponding positive electrode lead, a plurality of vent holes are formed inside the top layer conducting film and the non-electric-lead area of the bottom layer conducting film, the middle layer isolation film is located between the bottom layer conducting film and the top layer conducting film, and a plurality of conducting holes are formed in the middle layer isolation film. The pressure sensor has the good ventilation function, can conveniently and rapidly recognize pressure according to electric signals output by the negative electrode lead and the corresponding positive electrode leads, and has the advantages of being simple in structure, high in sensitivity, convenient to operate, low in cost and the like.

Description

technical field [0001] The invention relates to a pressure sensor with air-permeable function, which belongs to the technical field of medical sensors. Background technique [0002] The pressure sensor is an auxiliary medical device used in the hospital ward, which can be used for the alarm of the patient leaving the bed and the reminder of turning over at regular intervals. At present, the pressure pads commonly used in hospitals are made of air-tight films, which will cause users to feel uncomfortable due to wet skin on the contact surface, and even more serious pressure sores will be induced. [0003] In view of this, the inventor of the present invention conducts research on this, and specially develops a pressure sensor with a breathable function, so that the user can feel comfortable while monitoring the pressure. This case arose from this. Contents of the invention [0004] The object of the present invention is to provide a pressure sensor with air-permeable func...
