AI Technical Summary

Problems solved by technology

Therefore, once a patient with cardiac arrest is found, effective cardiopulmonary resuscitation must be carried out immediately after the heartbeat stops. However, some irregular actions during the cardiopulmonary resuscitation process will lead to the failure to effectively rescue the patient, thus endangering the life of the patient

Embodiment Construction

[0032] The invention provides a flexible action standardization instrument, which includes a pressing action signal acquisition unit, a signal conversion unit, a data processing unit, a bluetooth transmission module, a screen display unit, and a button battery.

[0033] The compression action signal acquisition unit is used to collect external heart compression action signals, using a flexible piezoresistive sensor, such as figure 1 As shown, the flexible piezoresistive sensor includes two membrane components, the membrane components are composed of PDMS and the rGO layer coated on the PDMS surface, the front of the membrane component has a pyramid array; the two membrane components are facing each other, and the surface The pyramid arrays fit together; when the user makes a pressing action, the sensor is deformed due to the user's action, and then generates a series of electrical signals. In this flexible piezoresistive sensor, the resistance of the upper rGo layer is R 1, ,...

Abstract

The invention provides an instrument for perfecting monitoring of standardization of cardiopulmonary resuscitation (external chest compression) actions. A sensor is attached to the chest of a to-be-saved patient, the sensor can be deformed under external chest compression actions with certain frequency and force of a saver, corresponding resistance variation is produced and led out in a form of electrical signals, the electrical signals are converted into digital analog signals by a device, the signals are compared with standard data in the instrument, and corresponding conclusions and recommendations are provided. The instrument has the advantages of being light in weight, simple in structure, easy to carry, convenient to operate, lower in cost and the like, has the potential of mass production and application and has better market prospect.

Description

technical field [0001] The invention relates to sensor, signal processing technology, motion feedback technology, field of sports medicine, wireless sensor network, internet of things and other fields. In particular, it relates to a flexible action standardizer based on a piezoresistive sensor with a pyramid interlocking structure, and belongs to the field of intelligent control. Background technique [0002] As we all know, in recent years, the number of people who died of heart disease is constantly increasing, and the death rate of patients who died of cardiac arrest is astonishingly high, because most patients with cardiac arrest have no aura symptoms and often develop suddenly , irreversible hypoxic brain damage can occur within minutes of cardiac arrest, and then transition to biological death. Therefore, once a patient with cardiac arrest is found, effective cardiopulmonary resuscitation must be carried out immediately after the heartbeat stops. However, some irregul...
