Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a combined cannula fixing device. Background Art

[0002] Tracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. When intubation is used, in order to avoid damage to the patient caused by shaking or movement of the tube, the tube needs to be fixed after intubation. At present, the intubation is generally fixed to the patient's face with tape. This method cannot restrict the patient's head, and the intubation will still be pulled when the patient's head moves. In addition, the use of tape is not suitable for some patients with facial trauma.

[0003] In response to the above problems, the prior art CN108904948B proposes a fixing device for hanging tracheal tube, which can restrict the patient's head and use a hanging tube hanging structure to fix the tube, which can effectively avoid the problem of tube pulling caused by the shaking of the patient's head. At the same time, it does not need to be fixed on the face, reducing facial discomfort.

[0004] However, the above device still has certain defects in application. Although the above device can fix the head, it cannot be adjusted. When used by patients, the head sizes of the patients are not consistent. Patients with larger heads may not be able to use it normally, while patients with smaller heads cannot achieve head restriction. At the same time, during the intubation process, the depth of the intubation is performed by experienced doctors. During the intubation process, it is often necessary to make small adjustments to the intubation. The traditional method is that the doctor holds the intubation tube for adjustment. This method is not convenient for controlling the insertion depth, and the problem of excessive amplitude often occurs. Therefore, it needs to be repeated many times, which increases the patient's pain. In response to the above problems, we provide a combined intubation fixing device to solve the above-mentioned problems. Summary of the invention
