Problems solved by technology

[0004] In the preparation process of the existing laryngeal mask, the mask body is formed by molding. Because the drainage channel is formed along the bottom of the mask body, it is a curved structure. The mask body itself is small, and the bottom of the mask body itself is a reduced structure, which is reserved for the drainage channel The space is small, resulting in low yield, and the drainage channel is small, and the drainage effect is poor

Embodiment 1

[0033] like Figure 1-10 As shown, a disposable laryngeal mask for emergency use comprises a cover body 1, the cover body 1 is communicated with an airway 2, a cuff 5 is installed on the cover body 1, the cuff 5 is connected with an inflatable tube 4, and the inlet of the inflatable tube 4 is The end is provided with a one-way valve 7 pointing to the cuff 5, and an indicator air bag 6 is also installed on the inflation tube 4. The air pressure of the cuff 5 is judged by observing the expansion degree of the indicator air bag 6, thereby ensuring the stable pressure of the cuff 5 and the sealing performance.

[0034] The cover body 1 is connected with a drainage pipe 3. Specifically, a drainage groove 12 is integrally formed on the cover body 1. The opening of the drainage groove 12 is arranged along the end face of the side wall of the cover body 1, and the opening of the drainage groove 12 passes through the sealant. A sealing cover plate 9 is installed. The lower surface of t...

Embodiment 2

[0040] like Figure 11-12 As shown, a disposable laryngeal mask for emergency use is different from Embodiment 1 in that after the airway 2 and the drainage tube 3 are buckled together, an operating handle 8 is fitted, and the operating handle 8 is processed with a slot for matching with the drainage tube 3. 23, and then position the air guide tube 2, the drainage tube 3 and the operating handle 8, and the installation is more convenient.

Abstract

The invention relates to a laryngeal mask, in particular to a disposable laryngeal mask for emergency treatment, which is characterized in that a drainage groove is arranged at an opening of a mask body, the opening of the mask body is of an open structure, more space can be provided, a larger drainage groove open area can be obtained, the open area of the mask body is reduced due to introduction of the open area of the drainage groove, and a sealing cover plate supports the open area of the drainage groove. In addition, due to the fact that the drainage groove is machined in the opening of the cover body and is of a smooth structure, the drainage groove can be formed through a mold more easily, the yield is high, the sealing cover plate is formed through extrusion molding, manufacturing is convenient, the sealing cover plate is installed at the opening of the drainage groove after being manufactured, installation is convenient, and the sealing effect is good. The cover body is simple in structure and easy to manufacture and form, and the sealing performance and the safety performance are improved.

Description

technical field [0001] The present invention relates to a laryngeal mask, in particular to a disposable laryngeal mask for emergency use. Background technique [0002] Laryngeal mask is mainly used in general anesthesia patients, emergency department, ICU and patients with emergency and resuscitation in various departments, patients with difficult airway, to assist patients in breathing, and it is widely used in clinical practice. [0003] The existing laryngeal mask mainly includes a cover body, the cover body is connected with an air guide tube, the cover body is also provided with a cuff, the cuff is connected with an inflation tube, and the cover body is connected with a drainage tube, wherein a drainage channel is integrally formed at the bottom of the cover body, The drainage channel is connected to a drainage tube to drain gastric juice, prevent gastric bloating, and at the same time prevent gastric juice from flowing back to the respiratory tract. The opening of the ...
