External massage automatic device for cardiopulmonary resuscitation

摘要

A useful model belongs to the field of medical technology, which can be used in the termination of human heart activity and disaster medicine under military field conditions, At home, in the workplace, in ambulances, etc.;The purpose of a useful model is to increase the continuous operation time of the equipment without charging the battery, so as to improve the reliability and durability of the work, And ensure the stability of the given parameters in the massage process.;In order to achieve this goal, a circular tension mechanism was established at the end of the tape covering the chest in the box platform placed by the patient,It is connected with the breast pad of the fabric tyre and the pulley on the output shaft of the mechanism,Including drive motor reducer,Overtaking clutch and torque sensor,The rotor is connected to the pulley shaft.;After automatically tightening the tape to determine its circumference before contacting with the breast, the chest compression mode is realized by winding the end of the tape on the pulley,After reaching the required tension, the reduction motor stops working,The clutch is closed and the decompression mode starts,It is provided by accumulating elastic deformation energy in the flexible plate and chest ribs. Slide the end of the tape off the pulley,Get him back where he was.
