The laryngeal mask capsule component, the indicator capsule component and the trachea component are used. This product consists of laryngeal mask intubation, inflation tube, indicating balloon, cuff, ventilation mask, machine end connector and inflation valve. The material of laryngeal mask intubation tube, inflation tube, indicating balloon, cuff and ventilation mask is polyvinyl chloride, the material of machine end joint is polypropylene, and the material of inflation valve is polyvinyl chloride nitrile stainless steel. The product is ethylene oxide sterilized. One-time use.
[method of use] oxygen is directly injected into the oxygen storage bag, the mask is placed on the face of the patient, and the mouth and nose are closed. The mask is fixed to the head of the patient using a fixing member, and oxygen is inhaled.
The ultrasonic nebulizer has no selectivity to the mist particles, so most of the drug particles produced can only be deposited in the upper respiratory tract such as the oral cavity and larynx, and due to the small amount of deposition in the lungs, it cannot effectively treat lower respiratory tract diseases. At the same time, due to the large mist particles and fast atomization produced by the ultrasonic nebulizer, the patient inhales too much water vapor, humidifies the respiratory tract, and the dry and thick secretions in the respiratory tract that originally partially blocked the bronchus absorb water and expand. The resistance of the respiratory tract may cause hypoxia, and the ultrasonic nebulizer may cause the liquid medicine to form water droplets and hang on the inner cavity wall, which has poor effect on lower respiratory tract diseases, large demand and causes waste.
