Description

Chest compression measuring device

Technical Field

The utility model relates to the technical field of medical treatment, in particular to an external chest compression measuring device.

Background

An automatic external defibrillator, also called an automatic external electric shock device or an automatic defibrillator, is a portable medical device which can diagnose specific arrhythmia and deliver electric shock defibrillation, and is a medical device which can be used by non-professionals to rescue a patient suffering from sudden cardiac arrest. In case of sudden cardiac arrest, the method for effectively stopping sudden death is the most effective method for defibrillation and cardiopulmonary resuscitation of a patient by using an Automatic External Defibrillator (AED) within "golden 4 minutes" of the optimal rescue time. Chest compressions are among the most important components of current freehand cardiopulmonary resuscitation techniques, and serve not only as support for artificial circulation, but also to produce a certain amount of ventilation even when the rescuer is reluctant to do artificial respiration. Therefore, it is particularly important to learn how to properly perform chest compressions.

The current measurement of chest compression parameters in the market is: the shape sensor is attached to the chest of a pressed patient (the shape sensor generates corresponding deformation along with the change of the shape of the chest), and the shape data of the shape sensor is used for calculating the chest compression parameters; the method comprises the steps that a function image corresponding to the shape of a shape sensor is built in a plane rectangular coordinate system according to the shape data of the shape sensor, and the initial shape of the shape sensor before pressing is the corresponding initial function image; and (3) a real-time function image corresponding to the shape of the shape sensor in the pressing process.

The scheme can accurately obtain parameters such as pressing depth, pressing frequency and the like; however, in the actual emergency process, a great deal of time is required to obtain data through calculation, which cannot be clearly seen; the pressing frequency is often obtained by means of calculation by utilizing a function image by depending on the personal operation capability of medical staff and feeding back the pressing frequency to a rectangular coordinate system, and the medical staff can only adjust the pressing frequency according to the result obtained by calculation, so that the method is very inconvenient.
