Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a non-invasive ventilation mask mandibular support set. Background Technique

[0002] During current surgeries, patients are anesthetized to reduce pain. Anesthesia includes local anesthesia and general anesthesia. General anesthesia is used in some major surgeries. The purpose of general anesthesia is to safely and effectively control the patient's nervous system to make the surgical process as stable and painless as possible, and at the same time minimize the patient's discomfort and the risk of postoperative complications to make the surgery safer.

[0003] Currently, general anesthesia methods mainly include non-intubated general anesthesia, laryngeal mask general anesthesia, and tracheal intubation general anesthesia. Especially in fiberoptic bronchoscopy examinations and surgeries, these anesthesia methods have many limitations in the use of fiberoptic bronchoscopes. For example, in non-intubated general anesthesia, the depth of anesthesia is often insufficient or causes respiratory depression. In laryngeal mask or tracheal intubation general anesthesia, the operation channel of the fiberoptic bronchoscope becomes narrow, which is very inconvenient. For example, a relatively large ultrasonic bronchoscope may not be able to pass through and be operated. In addition, for short and relatively highly stimulating surgeries, non-intubated general anesthesia has insufficient anesthesia depth, but using laryngeal mask or tracheal intubation general anesthesia causes great irritation to the pharynx and is not conducive to rapid recovery.

[0004] Therefore, the technical personnel in this field provide a non-invasive ventilation mask mandibular support set to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a non-invasive ventilation mask mandibular support set is proposed. The mandibular support soft pad on the bottom plate can solve the problem of posterior displacement of the tongue root caused by general anesthesia and serve as a base. The mask main body is fixed with a fixing band to ensure the sealing performance of the mask main body. Then, assisted breathing can be carried out through an anesthesia machine. A gastric tube orifice with a plug is designed on the mask main body. During general anesthesia, a gastric tube with an airbag can be inserted to prevent gastric distension. Moreover, an operation port is designed on the mask main body and is usually sealed by a sealing cover. The operation port is large enough to facilitate the operation of different endoscopes and various instruments. And the endoscopic clip can prevent the mirror from moving randomly during operation, and one endoscopic holder can be reduced.
