Description

Dental pad type fixation device for orotracheal catheter

technical field

The invention relates to the field of medical technology, in particular to a dental pad type fixing device for an orotracheal catheter.

Background technique

During medical operations, anesthesia is essential in order to reduce the suffering of patients. With the development of anesthesia technology, general anesthesia is becoming more and more important, and the proportion in some operations is also increasing, and it occupies a dominant position. After general anesthesia, the patient relaxes and loses respiratory function, and must rely on external force to maintain breathing. Oxygen supply and inhalation of a certain amount of volatile anesthetic gas. Before that, intubation is required. Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called endotracheal intubation. Provide the best conditions for unobstructed airway, ventilation and oxygen supply, airway suction and prevention of aspiration. Emergency tracheal intubation technology has become an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. Endotracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and fastest means in respiratory management. It is a basic skill that medical personnel must master proficiently. to a vital role. After tracheal intubation, in order to prevent the patient from biting the intubation tube in his mouth and causing suffocation or shortness of breath, it is necessary to place a tooth pad on the side of the intubation tube. Breathing is a more commonly used medical device.

As for the fixing device of the tracheal tube in the prior art, the general-purpose dental pads are mostly fixed by tape binding and fixed on the cheek of the patient, but this method is unreliable. If the fixed part is exposed to sweat, saliva, blood, oil stains, Erosion of cosmetics, etc., or after long-term fixation, the adhesive force of the tape decreases, or after being pulled, it is easy to detach the tube, endangering the life of the patient. This has happened many times in clinical medicine. The existing dental pads and The endotracheal tubes are fixed side by side, occupying a large space in the oral cavity, making the patient's lips open for a long time, which is very irritating to the patient, and the discomfort is obvious. The traditional method puts a lot of pressure on the tongue and oral mucosa, and many patients have backlogged injuries or even bleeding. Spots, the tape is fixed on the skin of the patient's cheek, which can not guarantee the effect, may fall off, and damage the skin. There is no strengthening measure for the connection between the proximal end of the endotracheal tube and the ventilator circuit. If there is a certain tension, breathing often occurs. Therefore, there is an urgent need to develop a dental pad type fixation device for the orotracheal tube.
