Description

Technical Field

[0001] The utility model belongs to the technical field of tracheal intubation, and in particular relates to a fixing device for tracheal intubation. Background Art

[0002] Tracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. Emergency endotracheal intubation technology has become an important measure in the rescue of critically ill patients with cardiopulmonary resuscitation and respiratory dysfunction. Tracheal intubation is an important rescue technique commonly used in emergency work. Oral endotracheal intubation is a commonly used operation in medical practice. After the intubation operation is completed, the endotracheal tube needs to be fixed to prevent the endotracheal tube from shaking or displacement. The existing fixation method is often fixed with tape, but because the patient is in an open mouth state, saliva can easily overflow from the patient's mouth and wet the tape, so the endotracheal tube will be unstable. The overflowing saliva will also contaminate the surrounding area or irritate the patient's skin. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a device for fixing an endotracheal tube to solve the problems raised in the above background technology.

[0009] To facilitate the fixing of the endotracheal tube to the center plate:

[0010] As a further improvement of the above technical solution: the component for positioning the trachea plug includes a fixing box arranged on the center plate, a sliding rod slidably connected to the fixing box, a positioning plate arranged at the bottom end of the sliding rod, and a spring sleeved on the sliding rod and used to connect the fixing box and the sliding rod.

[0011] The beneficial effect of this improvement is that when positioning the endotracheal tube, the positioning plate and the slide rod are pushed along the fixing box to the side away from the through hole, the endotracheal tube is inserted into the through hole, and the positioning plate fixes the endotracheal tube under the elastic action of the spring.

[0012] To facilitate fastening the center panel to the face panels:

[0013] As a further improvement of the above technical solution: the locking mechanism includes ear straps arranged on both sides of the central plate, a back strap arranged between the two ear straps, and a first elastic belt for connecting the back strap and the ear straps.

[0014] The beneficial effect of this improvement is that the loop formed by the ear straps and the back straps is put down along the head, the ear straps are hung on the ears, and the back straps are located at the back of the head, so as to fix the center plate and the face.

[0015] To adapt the ear straps to patients with different face sizes:

[0016] As a further improvement of the above technical solution: a second elastic band is arranged on the side of the ear strap away from the central plate.

[0017] The beneficial effect of this improvement is that by providing the second elastic band, the ear straps can be adapted to patients with different face sizes.

[0018] To position the ear straps and prevent them from rubbing against your face:

[0019] As a further improvement of the above technical solution: a silicone sheet is provided on the inner side of the ear strap.

[0020] The beneficial effect of this improvement is that a silicone sheet is provided on the ear strap, which can increase the fit between the ear strap and the face, and can not only be used to position the ear strap, but also prevent the ear strap from abrading the face.
