Wearable doctor motion acquisition device for cardio-pulmonary resuscitation and use method

Technical Field

The invention relates to the fields of medical auxiliary products, wearable equipment, sensor technology, man-machine interaction, robot technology and the like, and relates to a wearable doctor action acquisition device for cardio-pulmonary resuscitation and a use method thereof.

Background

Cardiopulmonary resuscitation (CPR) is a life-saving technique performed by rescuers (doctors) when rescued persons (patients) have cardiac arrest, and aims to restore and help the patients to maintain effective blood circulation of human bodies, ensure blood supply of important organs of the bodies, and finally realize spontaneous respiration and spontaneous circulation of the patients. If the cardiopulmonary resuscitation is not timely or the method is incorrect, the cardio-pulmonary resuscitation is easy to cause great damage to the body of a patient, and serious patients can cause brain death.

Chest compressions are an important step in the early cardiopulmonary resuscitation of patients with cardiac arrest. When performing chest compressions, the physician needs to be positioned on one side of the patient's body, kneel on the ground or stand at the patient's bedside. The doctor puts the palm root of one hand on the middle lower part of the patient's sternum, so that the transverse axis of the palm root is consistent with the long axis direction of the patient's sternum, and puts the other hand on the back of the front hand, and the fingers are overlapped and tilted and can not press the chest wall. The big arm and the small arm of the doctor are in a straight line and perpendicular to the chest of the patient, and the doctor can not swing by pressing down the upper half body with the palm. The compression and relaxation times are equal during compression, and the palm cannot leave the chest wall during relaxation. The frequency of chest compressions should be kept at 100-120 times per minute and the depth of compressions should be greater than 50 mm. The compression quality of cardiopulmonary resuscitation has a serious influence on the treatment effect, so that the compression quality can be hopefully improved by acquiring information of the compression process, feeding the compression information back to a doctor, and prompting and correcting the wrong compression action of the doctor. In addition, for the high-risk personnel who have sudden cardiac arrest risk, if can wear portable cardiopulmonary resuscitation auxiliary device, when taking place danger, can assist the person of suing and labouring to carry out cardiopulmonary resuscitation in the very first time, will strive for valuable time to patient's treatment.

Chinese patent 201180032606.8 proposes a cardiopulmonary resuscitation guidance apparatus placed on the chest of a patient, which uses an accelerometer to collect compression depth information and a pressure sensor to collect compression force information, but cannot judge whether the direction and position of compression are correct. Chinese patent 201811172178.9 proposes a cardiopulmonary resuscitation measurement device worn on the arm of a doctor and a related measurement method, but only the compression depth information can be collected by an accelerometer, and the compression direction information cannot be output. Chinese patent CN108785051B proposes a parametric monitoring device and method for cardiopulmonary resuscitation, which is worn on the wrist of the pressed hand and pressed by a pressing detection module to be closely attached to the back of the hand of the pressed hand through a motion tracker, so as to realize the collection and storage of the pressing duration, pressing frequency and pressing amplitude information of medical staff, and prompt through vibration and voice information, but this scheme cannot collect the pressing force and pressing position of the doctor, and the voice information is easily interfered in the noisy emergency environment. In addition, the feedback of the pressing action is carried out by equipment such as voice and a display in the prior patent scheme, the feedback efficiency of complex information such as pressing direction information is not high, the problems of environmental noise interference, vision shielding and the like exist in the occasions such as emergency treatment and the like, and the feedback is easily influenced by only depending on voice prompt or the display. Therefore, a device which can be conveniently carried by medical staff or high-risk people and can simultaneously measure the cardio-pulmonary resuscitation pressing information of the pressing frequency, the pressing depth, the pressing position, the pressing direction and the pressing duration and can feed back and guide the cardio-pulmonary resuscitation behaviors of doctors in real time through the sense of hearing, vision, temperature touch and vibration touch, or through video and voice prompt, and multi-channel information feedback is achieved to assist rescuers in rescuing patients with cardiac arrest, and the device has important significance for standardizing the chest pressing behaviors of doctors and rescuers and improving the cardio-pulmonary resuscitation quality and the survival rate of patients.
