Description

Trachea cannula subassembly with prevent stinging function

Technical Field

The utility model relates to a medical appliance, in particular to a trachea cannula component with anti-biting function.

Background

The tracheal intubation is a method of placing a tracheal cannula into a trachea or a bronchus through an oral cavity or a nasal cavity and a glottis, provides optimal conditions for unobstructed respiratory tract, ventilation and oxygen supply, respiratory tract suction and the like, and is an important measure for rescuing patients with respiratory dysfunction.

The prior tracheal intubation often has certain problems in the implementation process. In most cases, the patient loses consciousness or subconsciously bites the tracheal cannula, and the tracheal cannula can be bitten flat to influence the conduction of the tracheal cannula; even the tracheal cannula is bitten by the overlarge occlusion pressure, so that the tracheal cannula cannot be normally used. To prevent this, medical personnel often place bite blocks in the patient's mouth that are placed between the upper and lower molars to prevent excessive biting of the patient's upper and lower molars into the endotracheal tube. However, the bite block itself does not have the ability to self-anchor in the patient's mouth, and thus the bite block tends to slip into the patient's mouth and lose its bite-preventing effect. In order to prevent this, the bite block needs to be fixed in the mouth of the patient by using a pressure sensitive adhesive, the pressure sensitive adhesive is in direct contact with the skin of the patient, and the pressure sensitive adhesive needs to be torn off from the skin of the patient when the bite block is removed or replaced, so that the skin of the patient is easily damaged. In addition, it should be noted that the fitting degree of the bite block to the patient is not very strong, and the bite block is difficult to fix, so that the procedure for fixing the bite block by the medical staff is complicated and the efficiency is low.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a trachea cannula assembly with anti-biting function, which can effectively reduce the injury to the patient and simplify the operation process while ensuring the safe use of the trachea cannula by the patient.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a trachea cannula assembly with a bite-preventing function comprises a cannula tube body, wherein the trachea cannula tube body is provided with a body, a first end and a second end, the end part of the first end is connected with an external connector, an air bag is annularly arranged on the outer part of the body close to the second end, an inflation tube is further arranged in the body, one end of the inflation tube is communicated with the air bag, and the other end of the inflation tube extends out of the tube wall of the body and then is connected with a one-way inflation valve; the body is further sleeved with an anti-biting ring pad capable of moving along the axis direction of the body.

Furthermore, the anti-biting ring pad is of a circular ring structure.

Furthermore, the anti-biting ring pad is a smooth closed curved body.

Furthermore, the anti-biting ring pad is provided with a plug bush hole which is a polygonal through hole and is externally tangent to the outer part of the body.

Further, the plug bush hole is a through hole with a shape of 6-8 edges.

Furthermore, the second end is provided with a sputum suction port.

The working principle is as follows: when the trachea tube body is inserted in place, the medical staff adjusts the position of the bite-preventing ring pad on the body, so that the bite-preventing ring pad can be approximately positioned behind the teeth of the patient when the bite-preventing ring pad is placed in the oral cavity of the patient. In this state, when the patient closes the mouth, the anti-biting ring pad is abutted against the upper jaw and the lower jaw of the patient, and then the teeth of the patient cannot bite or large pressure acts on the cannula tube body.

Has the advantages that: through above-mentioned structure, the effectual trachea body that has avoided leading to because patient's tooth overjet is obstructed or is bitten the emergence of the broken condition.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

An endotracheal intubation assembly with an anti-bite function, as shown in fig. 1 to 3, includes an intubation tube body 100. Specifically, the cannula body includes a body 110 and a first end 120 and a second end 130 at opposite ends of the body. Wherein, the end of the first end is connected with an external connector 200 communicated with the body, and the second end guides the body to be inserted into the respiratory tract. In addition, an air bag 300 is further encircled at the outside of the second end and is communicated with an air tube 400 provided in the body. The other end of the inflation tube passes through the side wall of the body and then extends out of the body and is communicated with a one-way inflation valve 500, and the one-way inflation valve is communicated with the air bag in a one-way mode from the outside. Meanwhile, the body is also sleeved with an anti-biting ring pad 600 which can prevent the teeth of the patient from excessively acting on the body. Specifically, this prevent stinging ring pad adopts the silica gel that has certain support intensity and elasticity to support, and, prevent stinging ring pad can adopt multiple shape, for example: a cube, ellipsoid, cuboid, etc. to support the patient's upper and lower jaws. It should be noted that, after the bite-preventing ring pad is placed in the mouth, the bite-preventing ring pad is abutted against the upper jaw and the lower jaw of the patient, and at this time, the patient cannot realize strong occlusion. In order to be suitable for different patients, the anti-biting ring pad can be moved on the body along the axial direction of the body. In the specific implementation process, the state of the utility model in the patient is shown in fig. 4.

As a further improvement of the above embodiment, the bite-preventing ring pad has a ring-shaped structure as a whole in order to simplify the operation. Under this kind of structure, prevent stinging the distance between ring pad and patient's upper and lower jaw equals, need not the direction of rotation when medical personnel place and prevent stinging the ring pad.

As a further improvement of the above embodiment, in order to reduce the compression of the bite-preventing ring pad on the upper and lower jaws of the patient, the probability of pressure trauma caused by long-term use is reduced. The bite-proof ring pad is a smooth closed curved surface body. That is, when the bite-preventing ring pad acts on the upper and lower jaws of the patient, the pressure between the bite-preventing ring pad and the upper and lower jaws of the patient can be evenly distributed on the upper and lower jaws of the patient in a surface contact manner as much as possible, and the compression of edges and corners on the upper and lower jaws of the patient in the conventional structure is eliminated.

As a further improvement of the above embodiment, in order to prevent the bite-preventing ring pad from sliding on the body difficultly due to too large friction force between the bite-preventing ring pad and the body. The socket hole 610 of the anti-biting ring pad 600 is a polygonal through hole, and the socket hole is externally tangent to the outside of the body.

As a further improvement of the embodiment, when the plug bush hole is a through hole with a shape of 6-8 edges, the friction force between the anti-biting ring pad and the body is the most moderate, and the situation that the anti-biting ring pad slips to the throat of a patient due to insufficient friction force between the anti-biting ring pad and the body and medical staff are difficult to stir the anti-biting ring pad due to too large friction force can not occur.

As a further improvement of the above embodiment, the sputum suction port 131 is provided at the second end so that the present invention can be applied to patients with more sputum.
