TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to heart-lung resuscitation pressing device. BACKGROUND

[0002] Cardiac arrest is a very critical medical condition, which refers to the sudden stop of the heart's effective pumping function, leading to the interruption of blood circulation. If not intervened in time, it will rapidly endanger the patient's life. In this case, rapid implementation of cardiopulmonary resuscitation is one of the key measures to save lives. Among them, chest compression is an important part of cardiopulmonary resuscitation, which aims to temporarily replace the function of the heart by external force to squeeze the chest cavity, promote blood circulation, and provide essential oxygen and nutrients for important organs, especially the brain.

[0003] However, the traditional cardiopulmonary resuscitation mainly relies on the manual compression of medical personnel, which not only requires the presser to have professional skills and strength, but also requires continuous, regular and forceful compression to maintain effective blood circulation. Unfortunately, even well-trained medical personnel will face the risk of physical exhaustion when performing artificial compression for a long time, which not only affects the quality and efficiency of compression, but also may reduce the success rate of resuscitation due to the interruption of compression. In view of this, it is particularly important to develop a simple, portable and easy-to-use cardiopulmonary compression resuscitation device, which not only greatly improves the survival rate of patients with cardiac arrest, but also effectively relieves the physical pressure of medical personnel.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] 1. The support two is placed on the back of the human body, the driving motor is started, and the end face cam is driven to rotate.

When sliding to the toothed table, the pressing rod is bounced up under the action of the spring, the pressing rod is bounced up to the limiting device, and one-time up-down pressing is completed. Then, the end face cam continues to rotate, and when the top of the pressing rod is in contact with the top of the pressing rod, the next pressing can be continued.
