Description

Cardiopulmonary resuscitation appearance

Technical Field

The invention relates to the field of emergency medical equipment, in particular to a cardiopulmonary resuscitation instrument.

Background

Cardiopulmonary resuscitation is an emergency method for cardiac and respiratory arrest, and once cardiac arrest occurs, if immediate rescue recovery is not available, irreversible damage to the brain and other vital organs of a patient can be caused after 4-6min, so cardiopulmonary resuscitation after cardiac arrest must be performed immediately on site. On-site cardiopulmonary resuscitation is mainly divided into three steps: the airway is opened, artificial respiration and chest compression. The existing artificial respiration mode adopts mouth-to-mouth air blowing, which is an effective method for providing air for patients; the operator holds the nostrils of the patient with the thumb and the index finger without moving the forehead of the patient, so as to avoid the overflow of the blown air, deeply suck the air, try to open the mouth and cling to the mouth of the patient, form a airtight sealing state, blow about 800 milliliters of air into the mouth of the patient with moderate force at a speed of 1-1.5 seconds, and blow the air to the thorax of the patient. After the air blowing, the operator lifts the head to one side, and the hand pinching the nose is loosened at the same time, so that the patient can exhale conveniently. The artificial circulation is to form the pressure difference between the chest and the outside by the chest and the heart, maintain the blood circulation power, and supply the blood with oxygen to the brain and the heart after artificial respiration to maintain the life.

In the process of carrying out cardiopulmonary resuscitation in the emergency rescue process, a rescuer needs to kneel to carry out chest compression on a patient, the labor intensity is high, and mouth-to-mouth air blowing is carried out on the patient to carry out artificial respiration, so that the patient is unhygienic and cross infection of germs is easy to form; and when the patient is endangered, medical staff can not arrive at the site in time, and common site staff can not grasp the artificial cardiopulmonary resuscitation well, and the rescue opportunity of the patient is easily missed.
