Problems solved by technology
[0004] However, in practical applications, not all people are able to master professional chest compression techniques. In the actual compression process of patients, usually due to incorrect compression positions and methods, other injuries are caused to the patient's body, such as using The patient's liver is ruptured by the impact, and the fingers are not tilted up when pressing, which may lead to rib fractures and flail chest, resulting in pneumothorax and hemothorax. Patient life safety

Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] In practical applications, the quality of chest compressions is closely related to compression depth, compression frequency, and the degree of thoracic rebound. In actual rescue, sufficient compression depth is necessary to maintain a certain coronary perfusion pressure (Coronary Perfusion Pressure). , CPP), and CPP is currently the most direct indicator to predict whether a patient can return of spontaneous circulation (Return Of Spontaneous Circulation...

The invention provides an external chest compression control device, method and system. The device can be directly placed at a chest of a patient; when the patient suffers from external chest compression, after a signal processing circuit applies a generated excitation signal meeting the preset requirements to the patient, a current electrocardiograph (ECG) signal, a current chest impedance signal and a current pressing depth signal of the patient are simultaneously obtained; through processing of the current electrocardiograph signal, the current chest impedance signal and the current pressing depth signal, after being obtained, the current electrocardiograph signal, the current chest impedance signal and the current pressing depth signal which meet the preset transmission protocol requirements are transmitted to a mobile terminal for display when a communication with the mobile terminal is established, so that a rescuer adjusts an external chest compression method, position and the like, the external chest compression quality is ensured, the time is earned for further treatment of the patient, and the injury caused by the external chest compression in a blind zone to the patient is prevented.
Description
technical field [0001] The present invention mainly relates to the field of medical instruments, and more specifically relates to a chest compression control device, method and system. Background technique [0002] Cardiac arrest (CA), also known as sudden cardiac death (sudden death), will cause irreversible damage to the brain and other important organs of the patient after 4 to 6 minutes if the disease is not rescued in time. Therefore, cardiopulmonary resuscitation (cardiopulmonary resuscitation, CPR) after cardiac arrest must be carried out as soon as possible at the scene, so as to buy time for further treatment of heart disease patients, thereby improving the success rate of rescuing patients with cardiac arrest. [0003] At present, chest compression is the most commonly used method of cardiopulmonary resuscitation. The rescuer performs steady, regular, and uninterrupted pressure on the patient's chest compression site, so that the left and right ventricles of the he...
