Description

Bite-block capable of fixing tracheal catheter

Technical Field

The utility model relates to the field of medical appliances, in particular to a bite-block capable of fixing an endotracheal tube.

Background

Transoral tracheal intubation is a technique in which a specially-made tracheal catheter is placed into the trachea through the oropharynx and glottis. The technology can effectively and reliably establish an artificial airway, is clinically helpful for relieving airway obstruction, cleaning airway endocrine, ensuring the smooth airway and controlling the respiration of a patient, and is the most commonly used anesthesia and rescue technology at present for treating respiratory arrest, hypoxia and hypercapnia.

The current common tracheal catheter fixing methods comprise an adhesive tape fixing method, a tooth pad cun belt method and a fixer fixing method.

Adhesive tape fixing method: after oral trachea cannula operation, a bite block is arranged between the upper teeth and the lower teeth, then the tracheal catheter and the hard bite block are bound together by using an adhesive tape and fixed in the oral cavity, and the adhesive tape is stuck around the lips, the left cheek, the right cheek or the nose wings in an X or H shape.

Tooth pad cun-belt method: a strap with the length of 80 cm and the width of 1.5 cm is used, and after the tracheal catheter and the hard bite block are fixed together in a double-loop mode, the strap is knotted and fixed after being wound on the neck of a patient. When the two fixing methods are adopted, if special requirements (such as oropharyngeal surgery, oral examination, nursing and the like) are met, the bite block is not placed, and the tracheal catheter is placed at the left side or the right side mouth corner for fixing.

The fixing method of the fixer comprises the following steps: the tracheal catheter is fixed by using a specific fixer through a side screw, and a nylon buckle is buckled after a fixing belt is used for encircling the neck of a patient, and a wide and flat occlusal plate is used for replacing a bite block, so that the patient can be prevented from collapsing the tracheal catheter or pushing out the fixer through a tongue.

At present, various problems exist in the common tracheal catheter fixing method in clinical application, and the problems are serious, and even more, the conventional tracheal catheter fixing method can threaten the life safety of patients, and the conventional tracheal catheter fixing method comprises the following aspects:

(1) the single fixing mode at present cannot meet various clinical situations (such as oropharyngeal surgery, oral care and the like).

(2) The adhesive property of the adhesive tape is influenced by the adhesive tape material, the humidity and the greasiness degree of the adhesive part and the adhesive time, and when the adhesive part is excessively moist, greasy or the adhesive time is excessively long, the phenomena of insecure fixation and slipping of the tracheal catheter are extremely easy to occur, thus seriously threatening the life safety of patients.

(3) The adhesive tape is easy to stimulate mucous membrane and skin for a long time, and can induce allergy, so that the local skin has adverse reactions such as erythema, blister, eczema, ulcer, infection and the like; in addition, when the adhesive tape is highly adhesive, skin damage may be caused when the adhesive tape is torn off, and the adhesive tape is often used for patients with facial tissue swelling.

(4) The conventional bite block is made of high-density polyethylene resin, has extremely high hardness, and can effectively prevent a patient from being bitten by a soft tracheal catheter, but when the bite block presses tissue mucous membrane in an oral cavity for a long time, the bite block can cause oral mucosa ulcer and bleeding, and is particularly common for patients suffering from coma, severe infection and the like.

(5) When the patient needs to operate the oropharynx, only the tracheal catheter can be fixed at the oral angle, and the bite block is not arranged to obtain better operation visual field and space, and when the patient is in a agitation condition, the airway obstruction and even the tracheal catheter falling off can be caused by the fact that the patient bites down the tracheal catheter.

(6) Although the fixing effect of the fixing device is good, the situation of heavy displacement is seldom caused, however, the fixing device has large volume and cannot obtain good operation space, so the fixing device cannot be applied to operations of oral cavity, throat and the like.
