Description

Technical Field

[0001] The utility model belongs to the technical field of laryngeal masks, in particular to a laryngeal mask. Background Art

[0002] A laryngeal mask is a device for quickly establishing a breathing passage, and is used to maintain breathing and ventilation for unconscious patients. Existing laryngeal mask devices are usually provided with an L-shaped catheter, and a mask sleeve is fixed to the outer periphery of the end of the L-shaped catheter. The mask sleeve is connected to the inflatable bag through an airway. When in use, the catheter is inserted into the patient's throat, and then the inflatable bag is inflated, so that the mask sleeve swells and seals the trachea around, thereby quickly establishing a breathing passage. However, existing laryngeal masks have the following problems: the air we breathe is usually filtered and humidified by the nasal cavity, so that it will not cause infection and irritation to the trachea after being inhaled into the body. After using the laryngeal mask, external air directly enters the body. The air contains a large amount of bacteria and impurities, which can easily cause the tracheal surface mucosa to become dry and sticky, causing irritation, easily causing coughing and other interactions, and is also prone to bacterial infection.

[0003] For example, a Chinese patent with publication number CN206152036U discloses a medical laryngeal mask, including a laryngeal mask body, which mainly includes an inflatable mask body, the mask body is composed of an annular inflatable body, and an upper mask is provided on the inflatable body, the upper mask is connected to a ventilation tube, and the ventilation tube is communicated with the inner side of the upper mask; the inflatable body is connected to an inflation tube, the end of the inflation tube is connected to an inflation valve, and an inflation indicating airbag is provided on the inflation tube; it is characterized in that an annular heating branch is installed on the ventilation tube.

[0004] The patent has the following problems:

[0005] The prior art documents are not convenient for stably inflating and deflation of the laryngeal mask during use, and the laryngeal mask is not convenient for inflating and deflation when used inside the laryngeal cavity of the patient, thereby reducing the efficiency of placing the laryngeal mask inside the laryngeal cavity of the patient, and it is not convenient to fix and store the laryngeal mask when the laryngeal mask is used, and the inflation pipe is easily displaced, thereby reducing the safety of the laryngeal mask. In view of this, we propose a laryngeal mask. Utility Model Content

[0006] The purpose of the utility model is to provide a laryngeal mask in view of the above-mentioned technical problems, so as to facilitate inflation and deflation, improve the efficiency of laryngeal mask placement, and improve the safety of laryngeal mask use.

[0007] In view of this, the utility model provides a laryngeal mask, including an indicator airbag, and also includes: a bifurcated trachea is installed through one side of the indicator airbag, an inflation valve is installed through one side of the bifurcated trachea, a deflation valve is installed through the bottom of the bifurcated trachea, the external fixed sleeve of the indicator airbag is provided with a connecting sleeve, a connecting sheet is fixedly installed on the top of the connecting sleeve, and a connecting fleece sheet is fixedly installed on the surface of the connecting sheet.

[0008] Based on the above structure, air is introduced through the indicator balloon, and then the inflation valve is used to inflate the air when inserted into the patient's throat, and then the deflation valve is used to deflate the air at the end. This allows the laryngeal mask to be stably inflated and deflated when used in the patient's throat, thereby improving the efficiency of placing the laryngeal mask in the patient's throat. Then, the connecting piece belt on the top of the connecting sleeve is used in conjunction with the connecting fleece piece and the expansion hook piece, so that the indicator balloon part can be stored when the laryngeal mask is used in the patient's throat, thereby improving the safety of the laryngeal mask.

[0009] Preferably, an inflation tube is installed through the other side of the indicator airbag, a connecting port is installed through the other side of the inflation tube, and a laryngeal mask airbag is installed through the other side of the connecting port.

[0010] Preferably, the laryngeal mask airbag is made of epoxy glue, and a connecting tube is installed through the top of the laryngeal mask airbag.

[0011] Preferably, an air supply pipe is installed through one side of the connecting tube, and a tooth pad is provided on the external fixed sleeve of the air supply pipe, and a fixed handle is fixedly installed on the surface of the tooth pad.

[0012] Preferably, a ventilation pipe is installed through one side of the air supply pipe, and a connecting pipe is installed through one side of the ventilation pipe.

[0013] Preferably, the connecting pipe is made of epoxy adhesive, and the external movable sleeve of the connecting pipe is provided with an expansion sleeve.

[0014] Preferably, an expansion connecting belt is fixedly installed on the bottom of the expansion sleeve, and an expansion hook piece is fixedly installed on the surface of the expansion connecting belt.

[0015] The beneficial effects of the utility model are:

[0016] 1. The laryngeal mask allows air to enter through the indicator airbag, and then uses the inflation valve to inflate it when inserted into the patient's throat, and then uses the deflation valve to deflate it at the end. The laryngeal mask can be stably inflated and deflated when used in the patient's throat. The laryngeal mask can be deflated after use by the patient, making it easier to remove the laryngeal mask, thereby improving the efficiency of placing the laryngeal mask in the patient's throat.

[0017] 2. The laryngeal mask, through the use of the connecting piece belt on the top of the connecting sleeve and the connecting fleece piece in conjunction with the expansion hook piece, can store the indicator airbag part when the laryngeal mask is used in the patient's throat, making it difficult for the inflation tube to move and stably placing it, thereby improving the safety of the laryngeal mask.
