Problems solved by technology

[0005] (1) The structure of the existing laryngeal mask is relatively complicated, the volume is large, and the overall material of the mask bag is stiff, which increases the difficulty of inserting the laryngeal mask
In addition, the large volume and hardness of the laryngeal mask will cause trauma to the patient's pharyngeal structure during insertion
[0006] (2) The size of the gastric tube channel and the cuff in the existing laryngeal mask are mutually limited, and it is difficult to meet the needs of different groups of people
[0007] (3) For the reusable laryngeal mask, due to the repeated use of the gastric tube, the cuff will be worn out. Because the thickness of the cuff itself is thin, it will often be worn out by the gastric tube, resulting in the overall scrapping of the laryngeal mask
[0008] (4) In addition, the setting of the gastric tube in the cuff also increases the difficulty of positioning the laryngeal mask, often requiring repeated operations, causing secondary damage to the patient
[0009] (5) The current double-tube laryngeal mask is difficult to meet the needs of inserting gastric tube and airway tube

Embodiment 1

[0029] Such as figure 1 , figure 2 and image 3As shown, a laryngeal mask that is convenient for guiding the insertion device into the stomach includes an integrally arranged air guide main tube 3 and a connecting body 14, an elastic cuff 15 arranged on the periphery of the connecting body 14 for closing the larynx, and an elastic cuff with the elastic cuff The inflation and deflation device connected to the cavity of the bag 15, when inflated, the periphery 10 of the elastic cuff 15 is in close contact with the inner wall of the larynx to prevent impurities from gastric reflux from entering the patient's trachea.

[0030] The air guide pipe 3 is provided with an air guide channel with an inner diameter of 19-20mm, and the specific size can be determined according to actual needs. The two sides of the outer wall of the air guide main pipe 3 are respectively symmetrically provided with a guide vane 6 arranged along the length direction of the air guide main pipe 3, and the t...

Embodiment 2

[0041] The structure is basically the same as that in Embodiment 1, except that there is one guide vane 6, which is arranged on one side of the air guiding main pipe 3, and has a width of about 9-10 mm. And the end of the guide wing 6 close to the connecting body 14 extends below the bottom surface of the connecting body 14 to further enhance the guiding effect on the gastric tube. The use process of the laryngeal mask of this embodiment is the same as that of Example 1.

Abstract

The invention discloses a laryngeal mask convenient for guiding an insertion device into the stomach. The laryngeal mask comprises an air guide main tube with an air guide channel, a connection main body arranged at one end of the air guide main tube, an elastic sleeve bag fixed on the periphery of the connection main body and used for closing the laryngeal, and an air inflation / deflation device communicated with an inner cavity of the elastic sleeve bag, wherein the top surface of the connection main body is provided with an air outlet communicated with the air guide channel; the outer wall of the air guide main tube is provided with a first guide slot arranged along the length direction of the air guide main tube; a second guide slot is formed between the bottom surface of the connection main body and the elastic sleeve bag; and the first guide slot and the second guide slot are connected to form a channel for guiding the insertion device. Compared with the prior art, the laryngeal mask convenient for guiding an insertion device into the stomach, disclosed by the invention, has a simple overall structure; due to the first guide slot and the second guide slot, the insertion of a stomach tube or other devices is facilitated, and the abrasion of the mask bag caused by the stomach tube or other devices is reduced; and meanwhile, the size of the mask bag is not influenced by the size of the stomach tube or other devices, thus the practicability is high.

Description

technical field [0001] The invention relates to a laryngeal mask, in particular to a laryngeal mask which is convenient for guiding an insertion device into the stomach. Background technique [0002] The laryngeal mask is a new type of medical ventilation device, which is suitable for patients under anesthesia or drug sedation and patients who need emergency artificial ventilation support during first aid and resuscitation to ensure the patency of the upper airway. Compared with the traditional endotracheal intubation, the laryngeal mask has very prominent advantages. For example, the use of the laryngeal mask can greatly reduce the occurrence of choking or coughing caused by irritation, reduce throat pain and postoperative nausea symptoms, and the insertion is simple Yi Xue is considered to be the most important invention in the artificial airway in the past two decades. [0003] In the initial stage of use, the laryngeal mask is mainly used for artificial ventilation. For...
