Description
Technical Field
The invention relates to the technical field of implantable precise electronic equipment, in particular to a safety isolation type artificial respirator. The artificial respiration device is mainly used for assisting medical staff to carry out artificial respiration when rescuing patients, effectively isolating gas, secretion and body fluid between the patients and the medical staff, and guaranteeing the health and safety of the artificial respiration implementer under the condition of not influencing the implementation of the artificial respiration. The medical device may also be used to assist a trained professional in the non-medical area with sudden breathing and cardiac arrest personnel.
Background
After a coma patient or a patient with cardiac arrest gets rid of airway foreign matters and the respiratory tract is unblocked by a free-hand method, if the spontaneous respiration is not recovered, artificial respiration is required to be carried out immediately so as to ensure that oxygen is supplied to the patient uninterruptedly and prevent irreversibility damage of important organs caused by oxygen deficiency. The oxygen concentration in normal air is about 21%, and the oxygen concentration in the exhaled air of a human body can reach 16% -18% by using 3% -5% after the exhaled air is inhaled into the lung through breathing, so that the absolute value of the oxygen content in the artificial respiration process can be not less than that in spontaneous respiration as long as the ventilation quantity of a patient is slightly larger than normal during artificial respiration, the oxygen supply of important organs of the human body is effectively guaranteed, and the damage of the important organs caused by oxygen deficiency is avoided.
There are two types of artificial respiration methods commonly used at present, mouth-to-mouth respiration and mouth-to-nose respiration.
1. Mouth-to-mouth breathing
The method for opening the air passage is selected according to the state of illness of a patient, the patient is in a supine position, a rescuer puts one hand on the forehead of the patient, holds the nostrils of the patient with the thumb and the forefinger, holds the chin with the other hand to enable the head to lean backwards as much as possible, keeps the air passage in an open state, then deeply sucks a mouth, opens the mouth to seal the periphery of the mouth of the patient (the infant can be wrapped together with the nose), continuously blows air for 2 times into the mouth of the patient, the air blowing time is 1-1.5 seconds each time, the air blowing amount is about 1000 milliliters, the air blowing is stopped until the thorax is lifted, the mouth of the patient is loosened, the hand holding the nostrils is released, the face is turned aside, the air flow is exhaled by the ear hearing, then a fresh air is deeply sucked to prepare for the second air blowing, and the same air. If the patient does not recover the spontaneous respiration, continuous blowing is carried out, the blowing frequency of an adult is 12 times/min, the blowing frequency of a child is 15 times/min, and the blowing frequency of an infant is 20 times/min, but the blowing capacity is more important relative to the blowing frequency during blowing, the initial two times of blowing lasts for 1-2 seconds each time, the gas is discharged completely and then blown again, and the carotid artery pulsation, the color of the pupil and the color of the skin are checked within one minute until the patient recovers the resuscitation success, or dies, or is ready to be subjected to tracheal intubation.
2. Mouth to nose breathing
When the oral cavity of the patient cannot be opened due to oral trauma or other reasons, the patient can blow air through the mouth and the nose, and the operation method comprises the following steps: firstly, the airway of the patient is opened, the head is tilted backwards, and the lower jaw of the patient is held by hands to close the mouth. Deeply inhaling a breath, wrapping the nose of the patient with the mouth, forcibly blowing into the nostril of the patient until the chest is lifted, and opening the mouth of the patient after blowing to allow the breath to be exhaled. If insufflation is effective, the patient's chest can be seen to undulate with insufflation and can feel the flow of air exhaled.
Therefore, the rescuer inevitably comes into close contact with the patient regardless of mouth-to-mouth or nose-to-mouth artificial respiration, and thus the gas, secretions, body fluids, and the like of the patient are inevitably brought into contact with the rescuer. Since cardiopulmonary resuscitation occurs mostly in emergency situations, the rescuing medical personnel are inevitably exposed to danger. If a patient suffers from respiratory transmitted diseases such as tuberculosis in the epidemic phase, human avian influenza, sars, ebola, etc., the rescuer is likely to become infected by gas contact; if the patient suffers from digestive tract transmitted diseases, vomit is left in the oral cavity or vomit attacks in the artificial respiration process, the rescuer is likely to be cross-infected after contacting the vomit; if the patient suffers from perioral herpes and the rescuer is in close contact with the patient during artificial respiration, the possibility of infection with the herpes virus is very high; syphilis is a venereal disease caused by infection with treponema pallidum, which can be transmitted into the human body through the oral mucosa and can be cross-infected if no corresponding measures are taken during artificial respiration.
However, the rescue of the unconscious patient and the patient with cardiac arrest is carried out for minutes and seconds, and the rescuers are not allowed to confirm whether the rescued patients have infectious diseases or not before rescue. Therefore, most rescuers have no hesitation to adopt direct contact mouth-to-mouth or mouth-to-nose artificial respiration due to professional habits and instinctive reactions when implementing artificial respiration, and neglect the self health and safety. Therefore, in order to protect the health and safety of rescuers during cardiopulmonary resuscitation, an effective measure of gas, secretion, and body fluid isolation between rescuers and patients must be established.
Currently, the common isolation measure is an artificial respiration membrane. The structure of the artificial respiration membrane is simple, the main body is provided with a PVC membrane to form a disposable CPR barrier disinfection mask, and the middle respiration opening is made of ethylene oxide disinfected non-woven fabrics. Although the artificial respiration membrane can effectively block part of solid matters, gas, secretion and body fluid of a patient still penetrate through the non-woven fabric to the side of a rescuer, so that safety isolation fails. Aiming at the risks faced by rescue workers in emergency treatment at present and the defects of the current using method and equipment, the invention provides a safety isolation type artificial respirator to solve the problems.
