Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable laryngeal mask airway tube. Background Art

[0002] The laryngeal mask airway is an artificial airway often used in modern clinical emergency resuscitation and general anesthesia. It is mainly used to keep the airway open and ensure the patient's ventilation and oxygenation. The delivery of oxygen through the laryngeal mask airway tube can provide great safety protection for patients during surgery, so it has been widely used in medicine.

[0003] Most of the existing laryngeal mask airway tubes do not have a mounting structure on the trachea. When in use, the side of the trachea away from the breathing mask is directly placed on the ventilator connector. This connection method has poor stability. When pulled, the trachea is easily loosened from the ventilator connector, affecting normal oxygen supply. In addition, most traditional breathing masks are fixed to the patient's face with medical tape, which is more troublesome to use.

[0004] To this end, we proposed a disposable laryngeal mask airway tube. Utility Model Content

[0005] The utility model aims to provide a disposable laryngeal mask airway tube to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable laryngeal mask airway tube, comprising a breathing mask, a trachea is fixedly installed at the bottom of the breathing mask, a connecting sleeve is fixedly installed at the bottom of the trachea, a ventilator connector is arranged at the bottom of the connecting sleeve, two card slots are arranged on the outside of the ventilator connector, and blocks are fixedly installed at the two card slots on the inner wall of the connecting sleeve, a limiting frame is provided on the outer side of the breathing mask, a first connecting belt is fixedly installed on the left side of the limiting frame, a staple is fixedly installed on the front end of the first connecting belt, a second connecting belt is fixedly installed on the right side of the limiting frame, and a perforation is arranged on the second connecting belt.

[0007] Optionally, there are multiple perforations, and the multiple perforations are arranged in sequence from left to right on the second connecting band. This design is beneficial to the use of this laryngeal mask airway tube.

[0008] Optionally, a rubber ring is provided in the connecting sleeve at the upper part of the two clamping blocks, and the sealing performance can be improved by the rubber ring.

[0009] Optionally, a groove is provided on the staple, and the two sides of the staple can be pinched together by reserving the groove to reduce the diameter of the staple and facilitate removal of the staple.

[0010] Optionally, a branch pipe is fixedly installed on the left side of the trachea, an airbag is fixedly installed on the left side of the branch pipe, and a valve is fixedly installed on the left side of the airbag, and gas can be urgently delivered through the airbag by opening the valve.

[0011] Optionally, a cannula is fixedly mounted on the top end of the trachea, and can be inserted into the patient's airway through the cannula.

[0012] Optionally, a filter is fixedly installed in the trachea, and dust can be filtered through the filter.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Through the cooperation of the slot, the connecting sleeve, the first connecting belt, the second connecting belt, the perforation, the staples, the grooves, the rubber ring and the block, the breathing mask can be quickly installed and fixed on the patient's head, thereby further improving the convenience of use. At the same time, it can make the connecting sleeve and the ventilator connector more stable after installation, avoiding the problem that the trachea is easily loosened when pulled and affecting the normal oxygen supply.
