Problems solved by technology

However, at present, the drainage type laryngeal mask is inconvenient to operate because the curvature of the main tube does not match the curvature of the human oral cavity and esophagus. Mismatch of the esophagus often causes discomfort in the patient's throat and increases the pain of the patient

Embodiment Construction

[0023] Such as figure 1 As shown, the drainage type laryngeal mask of the present invention includes a cuff 1, a main pipe 2, and an inflatable tube 3. The main pipe 2 is provided with a ventilation chamber 4 and a drainage chamber 5. The bending angle of the main pipe 2 is 90 degrees, which is the same as the bending angle of the human esophagus. In addition, according to the different bending angles of the esophagus of different individuals, the bending angle of the main pipe 2 can also be set to any angle between 70 degrees and 100 degrees, and the free end of the main pipe 2 is provided with a joint 21, such as figure 2 As shown, the outer wall of the connector 21 is provided with a bayonet socket 22, the bayonet socket 22 includes a bayonet portion 221 and an opening 222, the bayonet portion 221 is approximately circular, the width of the opening 222 is smaller than the diameter of the bayonet portion 221, and the bayonet portion 221 is also Other shapes that can be sele...

Abstract

A drainage laryngeal mask comprises a mask bag, a main tube and a gas filling tube. An aerating cavity and a draining cavity are arranged in the main tube, the aerating cavity is communicated with an aerating hole on the mask bag, the tail end of the draining cavity extends out of the main tube to be arranged at the tail of a small end of the mask bag, a bending angle of the main tube ranges from 70 degrees to 100 degrees, and the section of the tail of the small end of the mask bag is elliptical. The drainage laryngeal mask brings convenience for medical staff to operate, reduces suffering of a patient and is good in sealing property, and gas is prevented from entering the esophagus of the patient to aggravate reflux of the stomach of the patient when gas flows through a catheter of the trachea of the patient.

Description

technical field [0001] The invention relates to a device for infusing a medium into or onto a human body, in particular to an intubation tube for the trachea. Background technique [0002] The laryngeal mask is a device that uses extraglottic ventilation invented and first advocated by Brain in 1983. In order to improve the clinical application effect of the laryngeal mask, there are currently three types of laryngeal mask: the first is the standard laryngeal mask It is also the most commonly used laryngeal mask in clinical practice. The basic structure includes a cuff, an airway, and an inflatable tube for inflating the cuff. It is mainly used to maintain the function of the respiratory tract and cannot perform drainage operations; The third type is the drainage type laryngeal mask, in addition to maintaining the function of the respiratory tract, it is also used to drain the esophageal reflux material. The lumen passes through the cuff and opens at the tip of the cuff, wh...
