Description
Technical Field
The invention relates to a medical instrument, in particular to an instrument applied to general anesthesia operation.
Background
At present, intubation-free general anesthesia is widely applied in clinic, such as painless gastrointestinal endoscopy, painless induced abortion, painless bronchofiberscope and the like, and intubation-free general anesthesia in an operating room is less applied at present and is limited to patients with short operation time, because the airway of the patients is not easy to control when intubation-free general anesthesia is carried out, the phenomenon of tongue falling is easy to occur, the airway is not smooth, the hypoxia of the patients is caused, and related complications after hypoxia are caused.
Respiratory depression caused by non-intubated anesthesia is very numerous, and uncontrollable airways allow anesthetists to perform as ice-coating. To avoid accidents as much as possible, physicians have paid more attention to airway control when administering non-intubated general anesthesia than even intubated general anesthesia.
To solve the problem, the chinese patent application publication No. CN101422635A published on 5/6/2009, "a mandibular supporting device", provides a device specially used for supporting the laxity of the mandible of general anesthesia patients without tracheal intubation, which mainly prevents or avoids the upper respiratory tract obstruction caused by glossoptosis of the patients, so as to relieve the risks of chronic hypoxia and carbon dioxide accumulation of the body of the patients caused by the obstructed ventilation of the upper respiratory tract or blocked ventilation. The structure is complex, the operation is complex, the flexibility is not enough, and the popularization is difficult in practical application.
In addition, considering that the mask ventilation is commonly used for anesthesia induction, in order to make the operation process of the mask easy and reliable, the Chinese invention patent 'mandibular mask synchronous fixing frame' with the publication number of CN104474622B, which is issued on 2/22/2017, comprises a support frame in a U-shaped structure, two ends of the support frame are respectively provided with a mandibular bracket arm capable of moving relatively, two mandibular bracket arms are respectively connected with a connected fixing belt, and the connected fixing belt is provided with a connecting piece capable of being connected with the ventilation mask.
