Description

Simple first-aid ventilation device for cardio-pulmonary resuscitation

Technical Field

The utility model relates to an emergency medical instrument technical field specifically relates to a cardiopulmonary resuscitation is with simple and easy first aid ventilation unit.

Background

Cardiopulmonary resuscitation (CPR) refers to emergency skills that restore vital signs to a patient using artificial respiration and chest compressions and electrical defibrillation when the patient's heart is suddenly stopped or stopped. Nearly 700 million people worldwide suffer from extrahospital cardiac arrest every year, and the number of the sudden cardiac death in China exceeds 54 million every year, which is equivalent to 1 cardiac arrest per minute. In view of the unpredictability and the paroxysm of the patient's breathing, cardiac arrest, the basic life support required by the patient needs to be completed by a "first witness", otherwise the gold rescue time is easily missed, increasing the risk of death. Practice proves that the effective rescue of CPR is carried out on a patient within 4 min after the patient has sudden cardiac arrest, the gold time for saving life is provided, and the survival rate of the patient can reach 49% -75%; if the rescue is not carried out in time, the survival rate is reduced by 7 to 10 percent every minute of delay.

In emergency treatment, establishing an effective artificial ventilation circuit in a short time is one of the keys of emergency success. Artificial respiration is a first aid method for spontaneous breathing cessation. During artificial respiration, the rescuer needs to bend over to kneel down, the head raising and jaw raising method is used for smoothening the airway of the rescuer, the nose of the rescuer is pinched, and the mouth of the rescuer is completely wrapped by the mouth for mouth-to-mouth blowing;

however, direct mouth-to-mouth artificial respiration has many disadvantages:

(1) Firstly, the method has infection risks, and particularly for some patients suffering from infectious diseases, the method is easy to cause cross infection of rescuers; in reality, many rescuers are ordinary people as the first witnesses, often do not have professional first aid knowledge, have the psychological conflict between the direct interface and the interface contact, and are difficult to accept the method. Moreover, under the background of virus epidemic, a certain risk exists when the mask is taken off in a public place to expose the mouth and the nose;

(2) Secondly, when non-professional persons carry out artificial respiration, the method cannot be mastered, gas is easy to leak from one side during blowing, the purpose of lung ventilation cannot be achieved, and if a patient has nasal bones or facial injuries, the patient is easy to be injured secondarily by wrong manipulations;

(3) In addition, the person to be rescued may be in a full stomach state, the wrong ventilation method may cause the person to be rescued to suck by mistake, and the air passage may be blocked by the sucked or secreted substances, so that the ventilation cannot be successful.

In conclusion, non-professional artificial respiration is difficult to meet the requirement of effective oxygenation during emergency operation, and the success rate of cardiopulmonary resuscitation is limited. In the process of first aid, the tracheal intubation is the most effective method for establishing the artificial airway clinically in an open manner at present, the method can effectively guarantee the ventilation function of a patient and prevent the patient from sucking by mistake, but the operation of the tracheal intubation is often carried out by matching with a laryngoscope, which is too complicated and difficult, and cannot be successfully completed by the ordinary people.
