Description

Laryngeal mask with suction tube

technical field

The utility model belongs to the technical field of medical instruments, in particular to a laryngeal mask with a sputum suction tube.

Background technique

The laryngeal mask is a safe and effective airway ventilation device that is less irritating to the patient. It can quickly and conveniently establish a breathing channel for the patient. Existing laryngeal mask with sputum suction tube is generally an inflatable laryngeal mask in which the sputum suction tube is integrally formed in the ventilation tube. Inconvenience to doctors, long-term use without cleaning will also cause infection, and the structure of the inflatable laryngeal mask is relatively complicated, and the operation is troublesome. During use, there may be a risk of gas leakage in the cuff and interruption of ventilation.

Contents of the invention

The purpose of this utility model is to solve the problem that the sputum suction tube of the existing laryngeal mask is easy to be blocked and difficult to clean, and to provide a sputum suction tube with simple structure, convenient operation, replaceable cleaning of the sputum suction tube, and safer use of the mask bag laryngeal mask.

The technical scheme adopted in the utility model is:

A laryngeal mask with a sputum suction tube, including a ventilation tube, a mask body and a silicone mask bag. The upper end of the ventilation tube is a ventilation tube joint, and the lower end is a mask body. It is arranged along a ring and is in the shape of an oval. An inflatable cavity is formed between the silicone mask and the cover body. The section of the ventilation tube is oval. The drainage channel and the sputum suction tube channel, the sputum suction tube channel is movably connected with the sputum suction tube matching the shape of the sputum suction tube channel, the lower end of the ventilation channel communicates with the inflatable cavity, and the drainage channel in the stomach runs through the ventilation tube and the cover in turn and connects with the The feeding hole set at the front end of the cover body is connected, the channel of the suction tube runs through the ventilation tube and forms an arc-shaped groove near the junction of the ventilation tube and the cover body; The mouth is connected with the upper end of the ventilation channel, the feeding port is connected with the upper end of the drainage channel in the stomach, and the suction port is connected with the upper end of the suction tube channel.

As an optimization, a plurality of sputum suction holes are opened at the part where the sputum suction tube is located in the arc-shaped groove.

Further, an epiglottis support is provided on the silicone cuff, and the epiglottis support is located above the outlet of the ventilation channel.

The beneficial effects of the utility model are:

1. Adopt the sputum suction device with flexible connection between the sputum suction tube and the sputum suction channel. When the sputum suction tube is polluted or blocked, the sputum suction tube can be replaced separately, which not only reduces the cost, but also reduces the discomfort of the patient;

2. Since the cuff is made of silica gel, it can effectively form a seal with the inner surface of the throat, and will not damage the inner wall of the mucous membrane of the throat, eliminating the potential safety hazard of air leakage during use;

3. The multiple suction holes in the arc-shaped groove of the suction tube can ensure that the oral secretions in multiple positions can be discharged from the suction tube in time;

4. An epiglottis bracket is set above the outlet of the ventilation channel on the silicone cuff, which can hold the epiglottis and keep the epiglottis away from the opening of the ventilation channel at the cover body, so as to prevent the epiglottis from blocking the ventilation channel.

The laryngeal mask with the sputum suction tube provided by the utility model has the advantages of simple structure, convenient use, easy replacement of the sputum suction tube and safer use.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

It can be seen from the accompanying drawings that the laryngeal mask with sputum suction tube includes a ventilation tube 1, a mask body 2 and a silicone mask bag 3. The upper end of the ventilation tube 1 is a ventilation tube connector 4, and the lower end is a mask body 2. 2 is one-time processing and molding, which is convenient for mass production. The silicone cover bag 3 is arranged circularly along the outer edge of the cover body 2 and is oval in shape, and can effectively form a seal with the inner surface of the throat without damaging the inner wall of the mucous membrane of the throat , the silicone cuff 3 is used to replace the existing inflatable cuff, which eliminates the safety hazard of air leakage during use; an inflatable cavity 5 is formed between the silicone cuff 3 and the cover body 2, and the section of the ventilation tube 1 is oval A ventilation channel 11 is provided at the center of the ventilation tube 1, and a gastric drainage channel 12 and a sputum suction tube channel 13 are respectively arranged at both sides of the ventilation tube 1, and a sputum suction tube channel 13 is movably connected in the sputum suction tube channel 13. The sputum suction tube 6 with matching shape adopts the sputum suction device that the sputum suction tube 6 is movably connected with the sputum suction channel 13. When the sputum suction tube 6 is polluted and blocked, the sputum suction tube 6 can be replaced separately, which not only reduces the cost, but also It can reduce the patient's discomfort. The lower end of the ventilation channel 11 communicates with the inflatable chamber 5. The gastric drainage channel 12 runs through the ventilation tube 1 and the cover body 2 in turn and connects with the feeding hole 21 arranged at the front end of the cover body 2.
