AI Technical Summary
Existing medical laryngeal masks require multiple adjustments when inserted into the patient's throat, which is inconvenient to operate and makes it difficult to fit the airbag to the respiratory tract.
An adjustable medical laryngeal mask was designed. An adjustment mechanism was set at the lower end of the tube, including an adjustment seat, a rotating seat, a ventilation tube and an inflation tube. The airbag was rotated slightly to achieve fit with the respiratory tract, avoiding air leakage and over-insertion.
The airbag can automatically fit the respiratory tract, which reduces the number of times the insertion position needs to be adjusted and improves the convenience and safety of operation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical laryngeal masks, in particular to an adjustable medical laryngeal mask. Background Art
[0002] The laryngeal mask airway is a specialized artificial airway management technology. It was successfully developed and used clinically in the mid-1980s and introduced in China in the 1990s. Its use has made significant progress and is now increasingly widespread. The laryngeal mask airway is a device used for respiration, anesthesia, and emergency treatment, effectively protecting the patient's airway and providing essential oxygen.
[0003] When using a medical laryngeal mask, medical staff insert the airbag of the medical laryngeal mask into the patient's mouth, trying to make the airbag extend into the bottom of the patient's throat. Medical staff need to adjust the insertion position many times when inserting the medical laryngeal mask, which is quite inconvenient. For this reason, we propose an adjustable medical laryngeal mask. Utility Model Content
[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an adjustable medical laryngeal mask. By slightly rotating the airbag, the laryngeal mask is easier to insert into the bottom of the patient's throat when used, so that the airbag fits more closely to the respiratory tract, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: an adjustable medical laryngeal mask, comprising a catheter and an adjustment mechanism;
[0006] The catheter has an inflation channel 1 and a ventilation channel 1 formed therein, and a ventilation hose is inserted into the ventilation channel 1;
[0007] Adjustment mechanism: It is arranged at the lower end of the catheter. The external fixed sleeve of the adjustment mechanism is provided with an air bag. The left and right ends of the rear side of the adjustment mechanism are respectively plugged into the inside of the inflation channel 1 and the ventilation channel 1. The lower end of the ventilation hose is located inside the adjustment mechanism. Through a small rotation of the air bag, it is easier to insert the laryngeal mask into the bottom of the patient's throat when using it, so that the air bag and the respiratory tract fit better.
[0008] Furthermore, the adjustment mechanism includes an adjustment seat, a rotating seat, a ventilation tube, a first inflation tube, an inflation channel 2 and a ventilation channel 2. A rotating seat is provided on the left and right sides of the rear end of the adjustment seat. The rotating seat is respectively connected to the left and right sides of the lower end of the catheter through cylindrical rotation. The interior of the adjustment seat is respectively provided with an inflation channel 2 and a ventilation channel 2. The rear side of the adjustment seat is respectively provided with a ventilation tube and a first inflation tube. The ventilation tube is connected to the ventilation channel 2, and the first inflation tube is connected to the inflation channel 2. The rear side of the ventilation tube is inserted into the interior of the ventilation channel 1, and the rear side of the first inflation tube is inserted into the interior of the inflation channel 1. The external fixed sleeve of the adjustment seat is provided with an airbag to facilitate the insertion of the laryngeal mask.
[0009] Furthermore, sealing seats are provided on the outside of the rear ends of the vent pipe and the first inflation pipe to prevent air leakage.
[0010] Furthermore, a retaining ring is provided inside the second ventilation channel, and the lower end of the ventilation hose is located at the rear side of the retaining ring to prevent the ventilation hose from going too deep.
[0011] Furthermore, a second inflation tube is provided inside the airbag, and the second inflation tube is plugged into the inside of the second inflation channel to facilitate inflation of the airbag.
[0012] Furthermore, the outer fixing sleeve at the upper end of the catheter is provided with a fixing frame to fix the catheter.
[0013] Furthermore, it also includes connector 1 and connector 2, wherein connector 1 is arranged on the upper surface of the catheter, connector 1 is connected to inflation channel 1, and connector 2 is plugged into the outside of the upper end of the ventilation hose to connect to external equipment.
[0014] Compared with the prior art, the beneficial effects of the present invention are: the adjustable medical laryngeal mask has the following advantages:
[0015] The adjustable medical laryngeal mask is inserted into the patient's mouth, and the airbag is extended into the respiratory tract. Due to the shape of the patient's respiratory tract, the rotating seat rotates, the adjusting seat rotates, and the sealing seat contacts the inside of the inflation channel 1 and the ventilation channel 1 respectively to avoid air leakage at the connection position of the adjusting seat and the catheter. The airbag rotates until the curvature of the patient's respiratory tract is similar, and then the ventilation hose is connected to the ventilator through the joint 2. The lower end of the ventilation hose is plugged into the inside of the ventilation channel 1 and extends into the inside of the ventilation channel 2 until the lower end of the ventilation hose contacts the rear side of the retaining ring to avoid the ventilation hose from going too deep and injuring the patient's respiratory tract. The upper end of the joint 1 is plugged with a syringe, and the syringe inflates the airbag. The airbag expands, and the rotating seat rotates again to fine-tune the position of the airbag. Medical staff do not need to adjust the position of the laryngeal mask multiple times, so that the surface of the airbag automatically fits completely with the inner wall of the patient's respiratory tract.
