Description

Cardio-pulmonary resuscitation integrated automatic device

Technical Field

The utility model relates to a medical emergency treatment instrument, in particular to a cardio-pulmonary resuscitation integrated automatic device.

Background

Cardiopulmonary resuscitation, also known as CPR, is a rescue measure taken for cardiac activity and respiratory arrest, i.e., chest compression or other methods are applied to form temporary artificial circulation and recover cardiac spontaneous pulsation and blood circulation, and artificial respiration is used for replacing spontaneous respiration and recovering spontaneous respiration, so that the purposes of recovering resuscitation and saving life are achieved. It can provide emergency oxygen supply to heart, brain and vital organs of whole body to minimum extent after sudden cardiac arrest of patient, and provide the most basic life support for patient.

The most critical step in cardiopulmonary resuscitation is the deployment of chest compressions for the patient. During chest compression, the patient should be kept lying in a hard region with the head as low as possible below the heart. The rescuer needs to perform chest compression by adopting the force vertically acting on the sternum of the patient. When the chest is pressed, the palm root of one hand is placed on the lower half part of the sternum of a patient, the middle point of the connecting line of the two nipples is positioned slightly below the position of the infant, the other hand is superposed on the infant, the fingers of the two hands are tightly buckled, the fingers are upward as much as possible, the chest wall and the ribs are prevented from touching, and the possibility of rib fracture is reduced. The frequency of chest compressions is at least 100 per minute with at least 5 cm sternal depression. The balloon mask ventilation method is the most clinically used out-of-hospital emergency oxygen supply mode at present, is generally carried out by medical personnel, and is a simple tool for carrying out manual ventilation. Compared with mouth-to-mouth breathing, the oxygen supply concentration is high, and the operation is simple and convenient. Especially, when the patient is in critical condition and is not as late as tracheal intubation, the pressurizing mask can be used for directly supplying oxygen, so that the patient can obtain sufficient oxygen supply, and the tissue hypoxia state can be improved.

Cardiopulmonary resuscitation is suitable for circulatory arrest caused by various reasons, including sudden cardiac arrest, ventricular fibrillation, extremely weak cardiac beat and the like, but the time for performing cardiopulmonary resuscitation on a patient is often determined by the patient's own constitution and disease course. Therefore, when the operation is carried out for a long time, the physical strength of medical staff is easily insufficient, and further tiny changes of the external chest compression pressure and the position are easily ignored, so that the situations of inaccurate positioning of the external chest compression part, posture deformation and the like are caused, and potential safety hazards are caused; mouth-to-mouth artificial respiration also has potential cross infection, the air input is different from person to person, and the oxygen can not be accurately quantified.
