一种气囊装置 技术领域
本实用新型涉及一种检测压力的装置，尤其是涉及一种气囊装置。
背景技术
目前很多领域都涉及到气压压力检测，在一些比较小的精密设备中，如何进行压力检测是需要考虑的问题，目前压力的测量多是直接采用传感器进行测量，而密封空间较大的话，误差也会比较大。对于坚固物体之间的承受压力，如物体A向物体B靠近时，中间的物体受到的挤压压力如果直接使用压力传感器会有限制，如何精确测量压力值是需要考虑的问题。
实用新型内容
本实用新型提供了一种气囊装置，解决了在两侧物体向中间靠近挤压，将对中间的物品接触的压力测量的问题，通过将压力转换成气压测量，使得测量精确，其技术方案如下所述：
一种气囊装置，包括设置有膜片的气室，在气室内设置有气压传感器，所述气室是封闭性的，气室介质为空气、惰性气体或者为流体。
所述气室外设置有外壳，用于固定装置。
所述气室内设置有电路板，所述气压传感器位于电路板上。
所述膜片采用橡胶膜。
所述气囊设置为半球体状。
所述电路板设置有无线发射装置，用于将信息发送到外面。
所述电路板由充电电池提供电能，所述充电电池设置在气室外，并与电路板电连接。
所述气室由膜片和外壳形成。
所述气室外设置有电路板，所述气压传感器通过电连接与电路板相连接。
所述气囊装置能够有效的测量挤压的压力值，构造简单、成本低、体积小、测量精度高、气室介质为空气或随性气体或为流体都可以，可适用于医疗器械、工业、理疗、美容等产品压力检测。
