Description

A kind of artificial respiration mask device that prevents close contact

Technical field

The utility model relates to the field of artificial respiration devices, specifically an artificial respiration mask device that prevents close contact.

Background technique

If a comatose patient or a patient with cardiac arrest cannot breathe spontaneously after removing foreign matter from the airway and unblocking the airway with bare hands, artificial respiration should be provided immediately to ensure uninterrupted oxygen supply to the patient and prevent irreversible damage to vital organs due to hypoxia. damage. The oxygen concentration in normal air is about 21%, and the human body can use about 3% to 5% after inhalation into the lungs. That is to say, the exhaled breath still contains an oxygen concentration of 16% to 18%, as long as we perform artificial respiration. The volume of air given to the patient is slightly larger than normal, so that the absolute value of the oxygen content is no less than that of spontaneous breathing. This can completely ensure the oxygen supply to the body's important organs and prevent damage to important vital organs due to lack of oxygen.

Choose a method to open the airway according to the patient's condition. The patient lies in a supine position. The rescuer places one hand on the patient's forehead and pinches the patient's nostrils with his thumb and index finger. The other hand holds the chin and tilts the head back as much as possible to keep the airway open. state, then take a deep breath, open your mouth to seal around the patient's mouth (for infants and young children, the nose can be wrapped together), blow into the patient's mouth 2 times continuously, each blow time is 1 to 1.5 seconds, and the blowing volume is 1000 milliliter or so until the chest is lifted, stop blowing, loosen the patient's mouth, relax the hands pinching the nostrils, turn your face to the side, listen to whether there is airflow out, and then take a deep breath of fresh air for the second Prepare for the first blow, and when the patient finishes exhaling, start the next similar blow. If the patient has not yet recovered spontaneous breathing, continuous insufflation is required. The insufflation frequency is 12 times/min for adults, 15 times/min for children, and 20 times/min for infants. However, it should be noted that the insufflation volume during insufflation is relative to the insufflation rate. The frequency of inhalation is more important. The first two insufflations should last for 1 to 2 seconds each time. Let the gas be completely discharged before insuffling again. Check the carotid artery pulse, pupil, and skin color within one minute until the patient recovers. Success, or death, or readiness for intubation. Among the above-mentioned artificial respiration processes, mouth-to-mouth artificial respiration is the most direct and easy to implement, and almost everyone can do it. However, mouth-to-mouth artificial respiration is in direct contact with the patient’s mouth, which is extremely unhygienic, and there are some poisoning patients’ mouths that have Toxins or other secretions affect the implementation of mouth-to-mouth artificial respiration. Some patients even develop muscle tension, trismus, and are unable to perform direct mouth-to-mouth respiration. This not only affects the timely rescue, but sometimes even endangers the patient's life.

To this end, the utility model designs an artificial respiration mask device that prevents close contact, which solves the problems raised in the above-mentioned background technology.
