Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a multi-channel oropharyngeal ventilation device. Background Art

[0002] Anesthesia is a comprehensive subject that includes multidisciplinary knowledge and covers a wide range. It not only meets the requirements of surgery, but also participates in the rescue work of various departments, gynecological painless delivery, painless abortion, etc. The anesthesia department needs to use the oropharyngeal access port to perform anesthesia surgery on patients to ensure the patient's normal breathing.

[0003] A multi-channel oropharyngeal ventilation device disclosed in publication number CN219001558U can ensure the oxygen supply efficiency of the device when supplying oxygen to the patient by setting the main air port and the auxiliary air port, and prevent one of the ventilation device ports from being blocked, while still being able to supply oxygen normally to ensure the safety of the patient's use. In addition, the device is designed to be separated from the external catheter, which can also reduce damage to the inside of the patient's oropharyngeal tube when the device is removed.

[0004] However, the multi-channel oropharyngeal ventilation device has the following disadvantages:

[0005] (1) After the existing oropharyngeal passage opening is placed in the oropharynx of the patient, it is usually fixed by tape or by medical staff. This not only easily causes the oropharyngeal passage opening to move in the oropharynx of the patient, affecting the ventilation effect, but also increases the burden on medical staff;

[0006] (2) Oropharyngeal access devices with hanging ropes on the market cannot change the length of the hanging rope according to different users. Usually, the hanging rope is adjusted by tying a knot. This adjustment method has poor fixation and is easy to loosen, resulting in the device falling off. Utility Model Content

[0007] 1. Technical issues to be solved

[0008] The technical problem solved by the utility model is to provide a multi-channel oropharyngeal ventilation device which is highly practical, can be easily operated and has a relatively simple structure. The utility model solves the problem that after the existing oropharyngeal channel opening proposed in the above-mentioned background technology is placed in the patient's oropharynx, it is usually fixed by tape or medical staff. This not only easily causes the oropharyngeal channel opening to move in the patient's oropharynx, affecting the ventilation effect, but also increases the burden on medical staff. The oropharyngeal channel openings with hanging ropes on the market cannot change the length of the hanging rope according to different users. The hanging rope is usually adjusted by tying a knot. This adjustment method has poor fixation and is easy to loosen, thereby causing the device to fall off.
