Description

An improved medical bite

technical field

The utility model belongs to the field of medical auxiliary equipment, in particular to a medical bite used in conjunction with a multi-chamber trachea catheter.

Background technique

Clinically, in order to maintain the patency of the airway of critically ill patients, an endotracheal tube needs to be inserted through the mouth. In order to prevent the patient from biting the endotracheal tube, it is necessary to use a medical bite to prop the teeth to support and maintain the patency of the endotracheal tube. However, the medical bite currently used clinically is composed of a hard tube and a tooth baffle set on the hard tube. The outer surface is too hard, and the patient's teeth will be uncomfortable when biting, especially for patients who are awake and have problems with their teeth. The patient feels more uncomfortable. Furthermore, the existing medical bite is separated from the endotracheal tube and needs to be fixed together with the endotracheal tube by adhesive tape, which is not only inconvenient to operate during use, but also easily causes the endotracheal tube to shift or even slip off. In addition, the existing medical bite cannot be fixed by the patient's head, and there is a risk of falling out of the patient's mouth, which is not conducive to the rescue of critically ill patients.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the existing medical bite, and provide an improved medical bite, which can make the patient comfortable when occlusal, and is convenient to combine with the tracheal tube at the same time.

The improved medical bite of the utility model includes a hard catheter, a tooth baffle set on the hard catheter, an elastic soft layer and an elastic sleeve for combining with the tracheal catheter, and the elastic soft layer covers the The outer wall of the hard catheter enters the patient's oral cavity below the tooth baffle and is closely combined with the outer wall of the hard catheter. The elastic sleeve and the elastic soft layer are an integrated structure, and its centerline is parallel to the centerline of the hard catheter , one side of the tube wall is provided with an opening for the endotracheal tube to enter the lumen of the elastic sleeve.

The above-mentioned improved medical bite also includes a tie, and the tie is fixed through two through holes provided on the tooth baffle, and the tie can fix the medical bite through the patient's head to prevent the bite from falling out of the patient's mouth.

In the above-mentioned improved medical bite, the frenulum is an integral elastic belt, the two ends of which are respectively fixed at the two through holes provided on the tooth baffle.

The above-mentioned improved medical bite has two laces, one end of the two laces is respectively fixed at the two through holes provided by the tooth baffle, and the other ends of the two laces are free ends. to connect.

The utility model has the following beneficial effects:

1. Since the improved medical bite of the utility model uses elastic soft material to cover the occlusal part of the hard catheter, the patient occludes comfortably, especially for patients who are awake and have dental problems.

2. Since the improved medical mouthpiece of the utility model is provided with an elastic sleeve that is convenient to be combined with the tracheal tube, and one side of the tube wall is provided with an opening for the tracheal tube to enter the lumen of the elastic sleeve, the mouthpiece and the tracheal tube It can be conveniently fixed together, and the endotracheal tube will not shift, which is convenient for medical care. At the same time, when the endotracheal tube does not need to be inserted, the elastic sleeve can also be used for sucking sputum through the oral sputum suction tube, which has strong practicability.

3. Since the improved medical mouthpiece of the utility model is provided with a tie, it is convenient to fix the medical mouthpiece through the patient's head and prevent the mouthpiece from falling off from the patient's mouth.

Detailed ways

The improved medical mouthpiece of the present utility model will be further described below through embodiments in conjunction with the accompanying drawings.

Example 1

The structure of the improved medical mouthpiece described in this embodiment is shown in Figures 1 to 4, including a hard catheter 1, a tooth baffle 2 set on the hard catheter, an elastic soft layer 3 and a The combined elastic sleeve 4, the tube hole of the hard tube 1 is circular, for the oral cavity suction tube to pass through, the tube wall cross section is square, and there is an arc on the bonding surface and the symmetrical surface of the elastic sleeve. Shaped groove, the tooth baffle 2 is two pieces, symmetrically distributed on the two occlusal surfaces of the hard catheter, the hard catheter 1 and the tooth baffle 2 are made of hard medical plastic. The elastic soft layer 3 covers the outer wall of the hard catheter that enters the patient's oral cavity below the tooth baffle, and is closely combined with the outer wall of the hard catheter. The elastic sleeve 4 and the elastic soft layer 3 are an integrated structure.
