Description

Emergency call manual auxiliary device for cardiopulmonary resuscitation

Technical Field

The invention relates to the technical field of medical instruments, in particular to an auxiliary device for manual cardiopulmonary resuscitation in emergency treatment.

Background

Cardiopulmonary resuscitation, abbreviated as CPR, is a life-saving technique taken for the heart and breath of sudden arrest. To restore spontaneous respiration and circulation, cardiopulmonary resuscitation requires the assessment of the safety of the site environment and the consciousness, respiration, pulse, etc. of the patient during the operation, and then confirms that the patient is not responding or breathing, and then ensures that the patient lies on the back on the flat ground or is padded under his shoulder with an external chest compression plate, and the first rescuer can adopt different positions such as kneeling or footstool, and places the palm root of one hand at the junction 1/3 in the patient's sternum and the palm root of the other hand at the first hand. The fingers do not touch the chest wall. During pressing, the elbow should be straightened and pressed vertically and downwards with 120 times/min for adult, and the pressing depth should be 5-6cm, and the thorax should be completely restored after each pressing. The pressing time and the relaxing time respectively account for about 50 percent, the root of the palm can not leave the chest wall when relaxing so as to avoid the displacement of the pressing point, the airway of the patient is ensured to be in an open state when pressing, one hand is placed on the forehead of the patient and then is pushed by the palm so as to enable the head to lean backwards; placing a finger of the other hand under the mandible adjacent to the chin bone; the mandible is lifted, so that the chin bone is lifted. Attention is paid to open the airway while a patient should be digged with a finger to remove foreign matter or vomit in the mouth of the patient, and a person having a denture should take out the denture, using 30: 2, the time for delaying the first compression can be shortened by the compression ventilation compared with the CPR starting, and the patient can normally inhale without deep inhalation before giving artificial respiration; all artificial breaths (whether mouth-to-mouth, mouth-to-mask, balloon-mask or balloon-to-superior airways) should be insufflated for more than 1 second to ensure that a sufficient amount of gas enters and undulates the thorax.

However, when the artificial cardiopulmonary resuscitation, because the physical power of the rescue workers is limited, after the start of pressing for 1-2 minutes, the quality of pressing by the operator begins to decline (the frequency and the amplitude and the chest wall reset condition are not ideal), the rescue workers need to be replaced, when the operation is performed again, the rescue workers need to find out the correct position and then press the correct position, the rescue time is delayed, secondly, when the artificial respiration is performed on the patient, medical workers are required to cover the face of the patient on the precious face after the pressing action is completed, the air bag is squeezed again, the operation is complex, and the rescue time of the patient is wasted. Therefore, an auxiliary device for emergency manual cardiopulmonary resuscitation is provided.
