Trachea intubation auxiliary device

Abstract

The invention discloses a trachea intubation auxiliary device which comprises a fixing clamp, a lip piece is fixedly installed on the fixing clamp, the fixing clamp is an arc-shaped clamping groove and conforms to the anatomical radian of lower jaw incisor teeth, an elastic rolling plate is fixedly installed on the fixing clamp, and the elastic rolling plate is naturally rolled into a circle when in an unopened state, and the elastic rolling plate can be straightened after being opened. The marking line can help an anesthetist to position the oral cavity position and assist in guiding trachea intubation during bronchofiberscope-guided tracheal intubation operation, the intubation success rate is increased, the intubation time is shortened, the device is small in size and ultrathin, the implantation method is convenient and rapid, the device can be implanted into a patient with the limited mouth opening degree, the structure conforms to the physiological dissection radian, the device has the advantages of small trauma to tissues around the oral cavity, slight pharyngeal reflex, small irritation to the cardiovascular system and high comfort level in the implantation process, and sober or lightly sedative patients can tolerate the device.

Description

technical field [0001] The invention relates to the technical field of anesthesia, in particular to an auxiliary device for tracheal intubation. Background technique [0002] General anesthesia is one of the most common anesthesia methods at present. Patients with general anesthesia are prone to various complications during the recovery period after anesthesia. Among them, tongue relapse is the most common respiratory complication, which is caused by anesthetics and muscle relaxation. The residual effect of the drug makes the muscles of the tongue base lack tension, and the mandibular angle and tongue muscles relax, causing the tongue base to fall and block the airway. [0003] When the back of the tongue causes incomplete upper airway obstruction, the patient will experience difficulty in breathing and snoring sounds of varying intensity with the breathing. When the back of the tongue causes complete obstruction, the snoring disappears instead, and only the breathing action...

AI Technical Summary

Problems solved by technology

However, fiberoptic bronchoscope-guided tracheal intubation requires a good operating space, and most patients with difficult airway have a relatively narrow oropharyngeal space, and it is difficult to expose the glottis. Clinically, anesthesiologists often need assistants when performing fiberoptic bronchoscope-guided tracheal intubation Lifting the jaw or protruding the patient's tongue to increase the oropharyngeal space consumes human resources and requires the patient's conscious cooperation

At the same time, fiberoptic bronchoscopy-guided awake tracheal intubation often requires the use of sedatives to relieve anxiety and pain of patients, but the use of sedatives may induce tongue drop and lead to airway obstruction
