Description

A safety isolation artificial respirator

technical field

The invention relates to the technical field of implantable precise electronic equipment, in particular to a safety isolation artificial respirator. It is mainly used to assist medical personnel to implement artificial respiration when rescuing patients, and at the same time effectively isolate the gas, secretions, and body fluids between patients and medical personnel, ensuring the health and safety of artificial respiration implementers without affecting the implementation of artificial respiration. The medical device can also be used to assist specially trained personnel in non-medical areas for sudden respiratory and cardiac arrest personnel.

Background technique

If the patient in a coma or a patient with cardiac arrest does not resume spontaneous breathing after removing foreign bodies in the airway and unblocking the airway with bare hands, artificial respiration should be given immediately to ensure uninterrupted supply of oxygen to the patient and prevent irreversible damage to vital organs due to hypoxia. sexual injury. The oxygen concentration in normal air is about 21%, and the human body can use about 3% to 5% after breathing into the lungs, so the oxygen concentration in the exhaled air of the human body can reach 16% to 18%, as long as the patient is given artificial respiration. The ventilation volume is slightly larger than normal, so that the absolute value of oxygen content during artificial respiration is not less than the oxygen content during spontaneous breathing, thereby effectively ensuring the oxygen supply of important organs of the body and avoiding damage to important organs due to hypoxia.

There are two commonly used artificial respiration methods, namely mouth-to-mouth breathing and mouth-to-nose breathing.

1. Mouth-to-mouth breathing

The method of opening the airway is selected according to the patient's condition. The patient is placed in a supine position. The rescuer puts one hand on the patient's forehead, pinch the patient's nostril with the thumb and index finger, and holds the chin with the other hand to tilt the head back as much as possible to keep the airway open. state, then take a deep breath, open the mouth to close the patient's mouth (infants and young children can be covered with the nose), and blow continuously into the patient's mouth for 2 times, each blowing time is 1-1.5 seconds, and the blowing volume is 1000 About milliliters until the chest rises, stop blowing, release the patient's mouth, and relax the hand holding the nostril, turn the face to the side, listen to the air to exhale with the ear, and take a deep breath of fresh air for the second Prepare for the next blow, and when the patient has finished exhaling, start the next blow. If the patient has not resumed spontaneous breathing, continuous insufflation should be performed. The insufflation frequency is 12 times/min for adults, 15 times/min for children, and 20 times/min for infants. The frequency of air is more important. The first two blows last for 1 to 2 seconds each time. Let the air be completely exhausted and then blow again. Check the carotid pulse, pupil, and skin color within one minute until the patient resumes recovery. Success, or death, or ready for intubation.

2. Mouth-to-nose breathing

When the patient has oral trauma or other reasons and the oral cavity cannot be opened, mouth-to-nose blowing can be used. Take a deep breath, wrap your mouth around the patient's nose, and blow forcefully into the patient's nostrils until the chest lifts up. After blowing, open the patient's mouth to allow the air to exhale. If the blow is effective, you can see the patient's chest rise and fall with the blow and feel the air exhaling.

Therefore, whether it is mouth-to-mouth artificial respiration or mouth-to-nose artificial respiration, the rescue operator is inevitably in close contact with the patient, so the patient's gas, secretions, body fluids, etc. are inevitably contacted by the rescuer. Because cardiopulmonary resuscitation mostly occurs in emergency situations, the rescue medical staff are inevitably exposed to danger. If the patient suffers from respiratory diseases, such as tuberculosis transmission, human avian influenza, SARS, Ebola, etc., the rescuer is likely to be infected due to gas contact; if the patient suffers from digestive tract diseases, residual vomiting in the mouth If the patient suffers from perioral herpes and the rescuer is in close contact with the patient during artificial respiration, the rescuer will be infected with herpes virus. In addition, syphilis is a sexually transmitted disease caused by Treponema pallidum infection, which can be transmitted into the human body through the oral mucosa. If no corresponding measures are taken during artificial respiration, it may be cross-infected.

However, every second counts for the rescue of comatose patients and patients with cardiac arrest, and the rescuer is not allowed to confirm whether the rescued person has an infectious disease before the rescue. Therefore, most rescuers do not hesitate to use mouth-to-mouth or mouth-to-nose artificial respiration with direct contact due to professional habits and instinctive reactions when implementing artificial respiration, ignoring their own health and safety. Therefore, in order to protect the health and safety of rescuers during CPR, an effective gas, secretion, and body fluid isolation measure between the rescuer and the patient must be established.

At present, the commonly used isolation measure is artificial respiration membrane. The structure of artificial respiration membrane is simple, the main body is made of PVC membrane to make a disposable CPR barrier disinfection mask, and the breathing port in the middle is made of non-woven fabric sterilized by ethylene oxide. Although the artificial respiration membrane can effectively block some solid objects, the patient's gas, secretions, and body fluids still penetrate through the non-woven fabric to the rescuer's side, resulting in the failure of safety isolation. In view of the risks faced by rescuers of artificial respiration during emergency and the defects of current use methods and equipment, we have invented a safety isolation artificial respirator to solve the above problems.
