Description

Lever-type active compression-expansion cardiopulmonary resuscitator

technical field

The invention relates to a cardiopulmonary resuscitator, in particular to a cardiopulmonary resuscitator which is erected at an oblique direction and utilizes the principle of leverage, and has an information indicating device.

Background technique

Traditionally, cardiopulmonary resuscitation (CPR) is used to provide first aid for patients whose heart and lungs have stopped functioning. However, the cardiac output that emergency personnel can cause by manual chest compression is at most only about 5% to 20% of the heart's voluntary contraction and beating output. Therefore, its first aid effect is usually not ideal. In order to overcome the shortcomings of the above-mentioned cardiopulmonary resuscitation (CPR), another kind of active compression/decompression cardiopulmonary resuscitation (ACD CPR) came out, combined with appropriate cardiopulmonary resuscitation assisting devices, to treat patients with cardiopulmonary arrest Carry out first aid to improve the hemodynamic efficiency of its heart, thereby enhancing its first aid effect.

In the current market, there are also some equipment and products that use cardiopulmonary resuscitation assisting devices. However, these products are all implemented in ways that generally increase the fatigue of emergency personnel, or are inappropriately large. In Taiwan Patent Publication No. 200826918, a cardiopulmonary resuscitation assist device (cardiopulmonaryresuscitation assist device) is disclosed, which is an auxiliary device for active compression expansion cardiopulmonary resuscitation (ACD CPR), and such a technical solution is disclosed in its embodiments , and although it is light, the disadvantage is that it is not easy to locate the patient, and it will affect the follow-up electric shock first aid, and there is no operation signal assistance, and the effect is not good. In addition, in U.S. Patent No. 5,295,481 [cardiopulmonary resuscitation assist device], the ambulance personnel must use the cardiopulmonary resuscitation assist device to reciprocate and continuously compress and pull up the patient's chest cavity to stimulate the heart to resume operation, and the ambulance personnel are quite tired; in addition, Similar technical solutions are also disclosed in US Patent Nos. 5,823,185, 6,397,843 and 5,891,062.

Know through above-mentioned actual observation, all there is one or another defect in these devices or methods, can't satisfy the requirement of fast high-quality cardiopulmonary resuscitator in life. Using traditional cardiopulmonary resuscitation (CPR) for first aid, although different first aid techniques (such as electric shock) can be quickly changed, but the rescue effect is not good, and the lives of patients are often lost, which is regrettable. With a portable cardiopulmonary resuscitator, there are also patients who are not easy to locate and lack of assistance without operating signals. In addition, using an inappropriately large cardiopulmonary resuscitator will not only make the ambulance staff quite tired, but also affect the quality of first aid, and the time cannot be extended, making it difficult to meet the requirements of rapid cardiopulmonary resuscitation.

Therefore outline practically, existing cardiopulmonary resuscitator has following various items shortcoming:

1. The cardiopulmonary resuscitator of the prior art is too large and improper, and the ambulance personnel are quite tired, which affects the quality of first aid, and the time cannot be extended, which is inconvenient to cooperate.

2. In the prior art, cardiopulmonary resuscitation is based on the cardiac output that can be caused by chest compression with bare hands. It is difficult to increase the effectiveness and cannot exert the effect of protecting the safety of patients.

3. The cardiopulmonary resuscitator of the prior art is not easy to set up, and it is not easy to locate the patient, which is a waste of time and increases the cost of inspection.

4. When the prior art is used, there is no operation signal assistance, as long as the frequency is indefinite or the force is improperly applied during the rescue period, it will lead to irreparable regret of life.
