Laryngeal mask and special joint thereof

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a laryngeal mask and a special connector thereof. The laryngeal mask comprises a base, a breather pipe, a soft rubber mask bag and an inflation pipe which are sequentially connected from top to bottom, the upper portion of the base is sleeved with a rotor, the rotor rotates relative to the base, an upper through hole and a lower through hole which are coaxial are formed in the rotor and the base respectively, a flexible piston is slidably connected into the upper through hole in a sealed mode, the externally-inserted branch air pipe is inserted into the flexible piston, the upper end and the lower end of the flexible piston can rotate and be staggered, a ventilation cavity is formed in the position, outside the lower through hole, of the lower portion of the base, and the ventilation cavity is connected with a ventilation connector used for being connected with an anaesthesia machine in a communicated mode. The laryngeal mask has the advantages of being convenient to adjust, smooth in drawing and pulling, good in sealing performance, easy to use and convenient to operate.

Description

Technical field [0001] The present invention belongs to the technical field of medical devices, and specifically, a throat and its dedicated joint. Background technique [0002] The throat is a safe and effective airway ventilation device that can be quickly and convenient to the patient. It is generally used in various departments, but existing laryngeal masks generally have airway operation, throat mask Insert the end leakage, so that the oxygen rolling into the airway is overflowing, the risk of hypoxia is greatly increased, and the risk of oxygen is low. At this time, manual hand or other material is required to seal, and a large number of studies in this industry For example, the patent authorized bulletin is CN111744087B, which is the invention of the airway operation of the throat mask, which is inhabitable, and when the operation of the airway operating tool in the throat vent cavity, the gas intake cavity can not operate One-way valve, can be placed in a working tool thr...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned scheme has the following problems: the airway operation tool needs to be adjusted to penetrate deeply into the human body, such as a bronchoscope. It is necessary to adjust the depth of bronchoscope insertion or rotate an angle to determine the specific position of the airway opening for better observation. The above-mentioned scheme is due to The excessive friction between the soft membrane of the annular hole and the soft membrane of the duckbill and the airway operation tool leads to the situation of "reverse curling" recorded in the manual when pulling out

At this time, the sealing is lost, resulting in air leakage

At the same time, because of the above reasons, when the airway operation tool is rotated, the pia of the annular hole and the airway operation tool are rotated integrally, causing the laryngeal mask body to be forced to rotate or shift, and finally the laryngeal mask body and the human throat are dislocated, affecting Normal use of the laryngeal mask

Similarly, based on the above two reasons, it is foreseeable that the adjustment of airway manipulation tools will also be inconvenient
