Non-pneumatic laryngeal mask with imbibition function

Abstract

The invention relates to a non-pneumatic laryngeal mask with an imbibition function. The existing laryngeal mask cannot discharge mucous secretion on the laryngeal part of pharynx in time, and a vent hole of the laryngeal mask is likely to block by epiglottis. The non-pneumatic laryngeal mask with the imbibition function is characterized by also comprising a connector and a flexible rubber capsule, wherein an inflating cavity is formed between the flexible rubber capsule and a mask body, the mask body is provided with a plurality of suction holes, a ventilation pipe is internally provided with a ventilation passage, a feed drain passage and a suction passage, the ventilation passage is communicated with the inflating cavity, the feed drain passage penetrates through the ventilation pipe and the cover body to be connected with a feed hole on the front end of the mask body, the suction hole is communicated with the suction passage, the connector is provided with an inflating opening, a feed opening and a suction opening, the inflating opening is communicated with the ventilation passage, the feed opening is communicated with the feed drain passage, and the suction opening is communicated with the suction passage. The non-pneumatic laryngeal mask is simple in structure, reasonable in design and good in sealing performance; the mucus and coagula on the laryngeal part of pharynx can be discharged in time, the vent hole is unlikely to block, and the injury on a patient is little.

Description

technical field [0001] The present invention relates to a non-inflatable laryngeal mask with liquid suction function, in particular to a kind of self-optimized structure that ensures the ventilation function and at the same time sucks out the mucus secretion in the throat through an external negative pressure source to achieve effective ventilation. The utility model relates to a non-inflatable laryngeal mask which prevents secretions from blocking the airway and bacterial infection and improves the patient's comfort, and belongs to the field of medical devices. Background technique [0002] The laryngeal mask is a safe and effective airway ventilation device that is less irritating to the patient, and can quickly and conveniently establish a breathing channel for the patient. With its excellent performance in dealing with common and difficult airways, it has become several commonly used airway ventilation treatment devices alongside endotracheal intubation and masks.

AI Technical Summary

Problems solved by technology

The laryngeal mask in the prior art has the following disadvantages: 1. The cuff is inflatable, the structure is complex, the operation is troublesome, and there is a risk of gas leakage in the cuff during use, which may cause ventilation interruption; 2. The cuff in the prior art It is difficult to control the inflation capacity of the cuff. Too much gas in the cuff can seal the throat, but it will compress the inner wall of the throat and easily cause capillary necrosis in the throat and neck; Easy to slide and shift, there will be an unsealed state, so that the secretion of the throat will block the airway hole, which may cause harm; Covering the epiglottis will affect the ventilation effect or even blockage, which may cause harm; 4. The laryngeal mask in the prior art will cause the patient's cardiovascular disease to varying degrees when the cuff is placed inflated and fixed and pulled out with suction and deflation. Systemic reactions, especially in elderly and frail patients with complications

This non-inflatable laryngeal mask esophagus sealing catheter has an unreasonable cuff structure design. When the cuff is placed, the sealing cannot be guaranteed, and the mucus and other secretions in the throat cannot be discharged in time during operation.

In addition, the stoma of the non-inflatable laryngeal mask esophageal sealing catheter is easily blocked by the epiglottis
