Abstract

The invention discloses a laryngeal ventilation pipe, which is made of PVC and comprises a small esophageal balloon, a ventilation catheter and a large pharyngeal balloon. The ventilation catheter isfurther provided with a balloon inflation tube, and the balloon inflation tube is connected with a pressure indication type air bag. The inner surface and the outer surface are both provided with antibacterial materials formed by coating of antibacterial material coating liquid. The laryngeal ventilation pipe made of the PVC material can provide an enough antibacterial effect; and particularly, the antibacterial effect on common pseudomonas aeruginosa is relatively high.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an airway ventilation tube; more specifically, relates to an air bag pressure indicating throat ventilation tube. Background technique [0002] In battlefield rescue, ensuring a clear airway and maintaining normal oxygen exchange is the primary task when rescuing severely wounded and cardiopulmonary arrest wounded. Rescuers must establish an artificial airway at the first time, so as to ensure that the wounded's heart and lungs can normally absorb from the external environment. Oxygen, and reduce the casualty's risk of suffocation and brain death caused by breathing disorders. Studies have shown that at least about 5% of the wounded died directly from suffocation caused by airway obstruction. [0003] As an artificial airway widely used in field first aid, the laryngeal ventilator belongs to supraglottic ventilation equipment, and is mainly used for airway ma...
