Negative-pressure suction-type dental pad for fixing tracheal catheter

Abstract

The invention relates to a negative-pressure suction-type dental pad. The dental pad comprises a baffle and a groove. The lower half part of the dental pad is designed to be arc according to the shapeof a tracheal catheter in an oral cavity. A one-way vent hole is formed in the groove, a large gap is formed between the groove and the tracheal catheter, air is discharged through force pressing, the gap is obviously reduced, the interior of the groove is in negative pressure, and accordingly the tracheal catheter is sucked on the dental pad. Then, an injector is used for pumping air, and the negative pressure is increased for reinforcement and fixing. According to the unique negative-pressure suction-type design, the higher the negative pressure is, the firmer fixing is, and through negative pressure, the diameter of a ventilated cavity of tracheal catheter can become large. For a common fixing method, by adopting positive pressure, the catheter is possibly extruded to be flat, and thecavity becomes small. According to the unique negative-pressure suction-type design, the dental pad is directly sucked to the tracheal catheter, the volume of occupying the oral cavity is small, the pain of a patient can be reduced, nursing for the oral cavity is conducted conveniently and can be conducted just through one person, and the labor is saved. The negative-pressure suction-type dental pad has the advantages of being simple and reasonable in structure, low in cost, firm in fixing and powerful in function.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure adsorption, anti-bite and gum-protecting tooth pad for fixing an endotracheal tube. Background technique [0002] Clinically, for critically ill patients and patients under general anesthesia, endotracheal intubation is required to help the patient breathe. Endotracheal intubation refers to the technique of placing a special endotracheal tube into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration. [0003] The traditional tracheal tube fixation method is to continue to use the dental pad and the tracheal tube to be fixed with adhesive plasters, and then directly paste them on the patient's both sides cheeks with adhesive plasters. This method has many defects: 1. The adhesive tape is easily affected by the sweat glands and oily ...

AI Technical Summary

Problems solved by technology

This method has many defects: 1. The adhesive tape is easily affected by the sweat glands and oily secretions of the skin, so that the adhesive tape and the skin are not firmly pasted, and there is still a large range of motion after the tracheal intubation is fixed, especially when the patient is restless or changes position 2. There may also be a phenomenon that the skin is stretched too tightly, which can easily cause discomfort to the patient, and even stimulate the skin to cause inflammation or epidermal ulceration, resulting in subsequent 3. The operation is complicated and often requires the cooperation of two people to complete; 4. Oral secretions are easily trapped on the adhesive tape to form a bacterial culture medium, causing the patient to have the risk of infection

However, most of the designs are complicated, expensive, and costly. There are many corners and gaps, and oral secretions and sputum are easy to stay, forming a bacterial culture medium and causing the risk of infection for patients.

[0005] And whether it is the traditional tape fixation method or the special endotracheal tube holder, most of them have the following defects: 1. In order to better fix the endotracheal tube and prevent the tube from falling off, a higher pressure is required, but the greater the pressure, the easier it is to squeeze 2. The oral cavity is sealed by adhesive tape or endotracheal tube fixer, and the tooth pad or catheter fixation device is too large, occupying too much area of ​​the oral cavity, and the patient's comfort is low. It is inconvenient to clean oral secretions, and oral care requires two people to cooperate, which is a waste of manpower; 3. Tongue movement will disturb the catheter, and the catheter will be disturbed to loosen the clamping part, resulting in the loosening of the tracheal intubation; 4. The occlusal part is made of hard materials, which avoids the problem of occlusion, but it is easy to cause damage to the patient's teeth, gums, and oral mucosa, which needs to be improved
