First-aid external chest cardiac resuscitation device and application thereof

Abstract

The invention discloses a first-aid external chest cardiac resuscitation device and an application thereof. The first-aid external chest cardiac resuscitation device comprises a base; the supporting columns are oppositely arranged on the two sides of the base in the width direction; a supporting frame is of an arc-shaped structure, and two ends of the supporting frame are slidably connected with the supporting columns respectively; a pressing pump is fixed in the middle of the supporting frame; a gas driving device is connected with the pressing pump and comprises a positive pressure pump anda negative pressure pump, and an electromagnetic four-way valve is arranged on a pipeline connected with the pressing pump; a transfer breathing machine is fixed in a rectangular box body structure ofthe base; a controller is respectively connected with a pneumatic driving device and the transfer breathing machine and controls the pneumatic driving device and the transfer breathing machine to start and stop; according to the scheme, the positive pressure pump and the negative pressure pump are ingeniously used for driving a plunger traction push rod of the pressing pump to drive the pressingplate to do lifting reciprocating motion, the lifting of a plunger can be achieved through switching of the electromagnetic four-way valve by means of switching of the electromagnetic four-way valve,and the thinking limitation of traditionally adopting single-drive equipment is broken through.

Description

technical field [0001] The invention relates to the field of emergency equipment, in particular to an emergency chest cardiac resuscitation device and its application. Background technique [0002] Cardiac Arrest (CA) refers to the sudden cessation of beating of the heart caused by various reasons in an unexpected situation and time, resulting in the sudden cessation of effective heart pump function and effective circulation, resulting in a serious loss of tissue cells throughout the body. Blood, hypoxia and metabolic disorders, if not rescued in time, they will lose their lives immediately. Sudden cardiac arrest is different from cardiac arrest in the terminal stage of any chronic disease. If correct and effective resuscitation measures are taken in time, the patient may be saved and recovered. [0003] With the improvement of living standards, people's entertainment and work items in daily life are becoming more and more abundant, and the resulting irregular life and decl...

Problems solved by technology

[0003] With the improvement of living standards, people's entertainment and work items in daily life are becoming more and more abundant, and the resulting irregular life and decline in physical fitness have become a major social problem, resulting in an increase in sudden diseases , especially in public places, there are more and more shock and sudden cardiac arrest incidents, and cardiopulmonary resuscitation is a necessary rescue method for cardiac arrest, but there are very few social personnel who have mastered the rescue skills of cardiopulmonary resuscitation , so that in the event of an emergency, it is often necessary to rely on 120 first-aid personnel, which makes a good rescue time missed, and the patient's life cannot be guaranteed at the first time, and the existing cardiopulmonary resuscitation rescue equipment is mostly of the same type Equipment that uses machinery instead of manpower to implement basic life support operations such as artificial respiration and chest compressions (such as the prior patent: 201720018143.4). Although such equipment can provide uninterrupted artificial circulation and ventilation support, its cardiopulmonary compression function is too mechanized , cannot be applied to audiences of different body shapes. In addition, the pressing drive of the indenter is a single drive mode, which makes the indenter difficult to control and run in a rough rhythm when it reciprocates, especially for those with weak systems or the elderly. Due to the relatively low toughness of bones and muscles, there may be some problems of rib fractures during the pressing process, and it is necessary to rely on the indenter driving device to assist the indenter to rise and return. However, this solution is only driven by a single driving device, which will As a result, it is difficult to control the stroke of the pressure head, and the sudden movement interruption causes equipment vibration and other problems. In addition, the current market-sold cardiopulmonary resuscitation machines are not intelligent enough, mainly through manual operation, which is time-consuming and labor-intensive, and sometimes misses rescue. prime time
