Method, device, and apparatus for measuring cardiopulmonary resuscitation compression depth, and storage medium

Abstract

A method, a device, and an apparatus for measuring cardiopulmonary resuscitation compression depth, and a storage medium are disclosed. The method comprises the following steps of: calibrating an acceleration sensor in a stationary state; the vertical acceleration components of the multi-axis acceleration signal are summed up according to the multi-dimensional angle change of the acceleration sensor in the operation state. Obtaining a velocity curve by first integrating the sum of acceleration components of each period; the velocity curves were modified according to the motion characteristicsof CPR, and the summation of acceleration components was modified by the obtained correction coefficients. The displacement of the acceleration sensor is obtained by performing a second integration onthe sum of the corrected acceleration components. The method obtains the displacement of the acceleration sensor, namely the pressing depth of the cardiopulmonary resuscitation through the secondaryintegration through the correction of the acceleration sensor and the twice-corrected acceleration signal obtained by the comprehensive correction method based on the correction of the velocity curve,thus providing more accurate reference and assistance for the resuscitator of the cardiopulmonary resuscitation and ensuring the quality of the cardiopulmonary resuscitation.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical assistance, and in particular to a method, device, device and storage medium for measuring compression depth of cardiopulmonary resuscitation. Background technique [0002] Cardiopulmonary resuscitation (CPR) refers to a first-aid technique to rescue the patient from the borderline of death in order to grasp the patient's vitality urgently when a person's breathing and heartbeat stop due to some factors, resulting in sudden death. When performing CPR, the rescuer presses on the sternum on the upper side of the chest. This compression replaces the patient's heart and can cause oxygenated blood to circulate throughout the living body. As an indicator of chest compressions, compression operations with a compression depth of more than 5 cm and a compression frequency of 100-120 times per minute are considered effective. In China, the emergency rescue network system has not yet been p...

Problems solved by technology

[0004] However, when using an acceleration sensor for distance measurement, due to the limited accuracy of the acceleration sensor and interference such as vibration in the actual application process, the acceleration sensor will generate noise signals and errors

After two integrations, the error is accumulated and magnified, and eventually the error of the distance measurement result becomes larger and larger as time accumulates. These problems greatly limit the application of the acceleration sensor in measuring relative motion displacement, while the high-precision Accelerometers are expensive

[0005] The biggest problem with current cardiopulmonary resuscitation aids is poor portability. Another disadvantage is that they only feed back pressure without real-time feedback. More effective compression depth for correction operations
