Description

Inner tube fixer structure of endotracheal tube bracket

The invention relates to an inner tube fixer structure, in particular to an inner tube fixer structure used in an endotracheal tube stent.

Nowadays, the way medical staff fix the endotracheal tube for the patient is to extend the endotracheal tube from the patient’s mouth. After the endotracheal tube extends into the patient’s mouth to the trachea, the endotracheal tube needs to be fixed, and the fixation method is known. Some use cotton rope or gauze strips with breathable tape to attach to the patient’s face for fixation purposes, but cotton rope or gauze strips and breathable tape covering the patient’s face for a long time will cause pressure sores and cause the patient’s facial skin to be red and swollen. , Pain or even breakage or ulceration, so medical staff need to perform regular replacement actions, but according to statistics, even if there are regular replacements, the skin damage rate caused by the medical device pipeline is still 30.5%, which is fixed The risk of damage to the endotracheal tube is the highest, and the process of using cotton rope or gauze with breathable tape to attach to the patient’s face to achieve fixation will also require changing hands or operations due to different operating methods or procedures. Two or more people are needed to fix the endotracheal tube, and then the endotracheal tube can be fixed in the patient's mouth.

In order to improve the above problems, related companies have developed and fixed endotracheal tube. For example, the endotracheal stent structure described in the U.S. Publication No. 20160361509 and U.S. Publication No. 20160271349. The endotracheal stents in the above patents mainly include internal tube fixation. Veneer, veneer with transverse slide rail or chute, and strap connected to veneer, the inner tube fixer is required First connected to the horizontal slide rail or chute, the medical staff can adjust the relative position of the inner tube holder and the horizontal slide rail as required, and then perform the intubation operation on the endotracheal tube fixed to the inner tube holder. The inner tube fixer is fixed on the veneer, so that when medical staff fix the endotracheal tube to the inner tube fixer for intubation, the excessive volume of the veneer will interfere with the operation of the medical staff or block the medical staff The line of sight affects the intubation operation, resulting in the intubation operation being unable to be performed quickly and effectively, and too long operation time may cause harm to the life of the patient.

In addition, more traditional endotracheal fixers are mostly used to fix the endotracheal tube with clips or straps as described in U.S. Publication No. 20160361509 and U.S. Publication No. 20160271349. When medical personnel are required to assist the patient to replace the trachea In the case of the inner tube, this kind of traditional inner tube holder is easily pulled to the endotracheal tube, causing the risk of endotracheal tube displacement or endotracheal tube slippage.

In addition, after the conventional endotracheal tube extends into the patient’s mouth to the trachea and is fixed by the inner tube fixator, the inner tube fixator will cover a large area and stick to the patient’s face, so that if the patient performs invasive treatment or examination, When performing treatments such as endoscopic dressing of the thoracic cavity and digestive tract, the endotracheal tube fixation device needs to be removed before other invasive treatments or inspections can be performed, but the removal of the endotracheal tube fixation device is extremely easy Displacement or slippage of the endotracheal tube may endanger the life of the patient. After the invasive treatment or examination is completed, it is necessary to fix the endotracheal tube fixation device to the patient’s face. These steps are also extremely important. It is easy to cause the risk of endotracheal tube displacement or endotracheal tube slippage.

Based on the above reasons, the traditional endotracheal tube stent has many problems that need to be improved, and there is still room for improvement.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide an endotracheal stent internal tube fixer structure that can be operated by one person with one hand and can avoid obscuring the sight of medical staff.

Another main purpose of the present invention is to provide an endotracheal stent structure and a method for using the endotracheal stent that can avoid pressure sores on the patient's face.

Another main purpose of the present invention is to provide an inner tube of an endotracheal stent with a structure that can be adjusted and displaced on the assembly body as required, and there is a space for medical operations between the assembly body and the patient’s nose and mouth. Fixer structure.

Another main purpose of the present invention is to provide an endotracheal tube holder structure that can be tripped to replace or adjust the endotracheal tube through simple operations, and can avoid pulling in the tripping operation.

Another main purpose of the present invention is to provide an endotracheal tube holder structure that can prevent the endotracheal tube from being detached due to accidental touch or the patient's self-unbuckling.

According to the object of the present invention, the present invention provides an inner tube holder structure of an endotracheal tube stent. The inner tube holder structure includes a main body and a clamping assembly. The upper side of the main body is formed with a front abutment side and a rear abutment side. , The outer side and the inner side of the anterior side are respectively provided with a pressing portion and an engaging convex portion, and a first exhibition piece and a second exhibition piece adjacent to each other are formed under the main body, the first exhibition piece and the second exhibition piece There is a displacement space between the exhibition pieces, and the side of the first exhibition piece is provided with a set of connecting parts, and the second exhibition piece is provided with a limiting member and a push button, and the clamping assembly is arranged on the first exhibition piece. Below the display piece, and the clamping assembly is composed of a first clamping piece and a second clamping piece and a set of extension parts, and the assembly and extension parts pass through the assembly part and interact with the limiting part. Assemble and connect the first clamping piece and the second clamping piece to each other, so that the medical staff can first connect the trachea The inner tube is arranged between the first clamping part and the second clamping part, the endotracheal tube can be intubated, and the inner tube fixer structure on the endotracheal tube will not interfere with the operation of medical staff Or block the sight of medical staff and affect the intubation operation. In this way, the intubation operation can be performed quickly and effectively, and then the inner tube fixer structure can be combined with a group that has an operation space between the patient’s nose and mouth. It is designed so that the endotracheal tube can be fixed in the patient’s oral cavity and an operating space is formed between the patient’s nose and mouth and the assembly, so as to avoid pressure sores on the patient’s face, and can be operated by one person with one hand and can avoid shielding medical care The function of the person watching the line of sight, in addition, by pressing the pressing portion to drive the engaging convex portion to leave the assembly body, the inner tube holder structure can be displaced on the assembly body to reach the inner tube holder The structure can be adjusted and displaced on the assembly body according to needs, and there is an operating space for medical actions between the assembly body and the patient’s nose and mouth, so that medical staff can perform other medical actions on the patient’s nose and mouth. In addition, Press the push button to drive the limiter away from the assembling and extension part, and the assembling and extension part can be detached from the assembling part, so that the buckle can be released to replace or adjust the endotracheal tube through simple operation, and the solution The buckle operation can avoid the effect of pulling, and the push button of the second spread is arranged on the side of the inner tube fixer structure, which can effectively prevent the endotracheal tube from being detached due to accidental touch or the patient's self-unbuckling .
