Description

Tracheal tube fixer capable of adjusting oral position

Technical Field

The utility model relates to the technical field of medical devices, in particular to an endotracheal tube fixer capable of adjusting the position of the oral cavity.

Background Art

Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. Endotracheal intubation is one of the clinical skills that all clinicians must master. It is an important means of establishing advanced airway in emergency and respiratory treatment for critically ill patients. It is an important part of general anesthesia and an extremely important part of undergraduate education for medical students. Endotracheal intubation is an invasive operation technique that can cause damage to the oral mucosa, tracheal injury, joint dislocation, tooth injury, and severe stimulation of the vagus nerve can lead to cardiac arrest. This technology is difficult, and effective methods and equipment are extremely critical.

In the prior art, endotracheal tube fixers on the market generally need to be worn on the patient's face by means of straps. For better fixation, it is usually necessary to stick rubber pads on both sides of the cheeks to assist in fixation. The disadvantage is that the strapping and sticking of the rubber pads greatly affect the comfort of use of the device. Long-term binding and fixation may even cause pressure sores, facial discomfort, and headaches. In addition, in order to make the fixed position of the endotracheal tube adjustable, the current endotracheal tube fixer is adjusted by setting too many accessories and structures on the fixer. The endotracheal tube fixer is usually disposable. A pair of endotracheal tube fixer devices contains components made of multiple different materials and relatively complex matching structural components, which increases the production, assembly, and use costs of the endotracheal tube fixer device, such as material, process, and mold costs. Therefore, an endotracheal tube fixer with a simple structure and easy to use is proposed to improve the above-mentioned disadvantages.

Utility Model Content

In order to solve the above technical problems, the utility model provides an endotracheal tube fixer capable of adjusting the position of the oral cavity.

The utility model is implemented by the following technical scheme: an endotracheal tube holder capable of adjusting the position of the oral cavity, comprising a supporting component and a tube fixing component, wherein the supporting component comprises a C-shaped portion and a first arc-shaped bar and a second arc-shaped bar respectively arranged at two ends of the C-shaped portion, a tooth groove is arranged on a side away from the first arc-shaped bar and the second arc-shaped bar, and the tube fixing component is arranged between a side where the first arc-shaped bar and the second arc-shaped bar are close to each other, and the tube fixing component comprises a connecting portion and two lateral limiting portions arranged on the upper and lower sides of one end of the connecting portion.

Through the above technical scheme, a C-shaped supporting component is used, and the supporting component can be placed in the patient's mouth to be worn similar to a denture, and then the intubation fixing component is used to fix the tracheal intubation. No additional supporting fixing structure is required, and no auxiliary such as straps and rubber pads are required, so as to avoid restraint on the patient's head and face during use, and improve the comfort of use. At the same time, only two components of the one-piece molding structure are required, which can be made of the same material, have a simple structure, are easy to produce and use, and can effectively reduce the production and use costs of disposable medical devices, while reducing the subsequent processing costs and environmental pollution pressure caused by material consumption.

As a further improvement of the above solution, the connecting portion is in a rectangular shape, and a pipe clamping groove is provided on one side of the connecting portion.

Through the above technical solution, the connecting part is used for the matching connection between the cannula fixing component and the supporting component, and the tube clamping groove is used for clamping and fixing the tracheal cannula.

As a further improvement of the above scheme, an arc-shaped protrusion is provided on the side where the first arc-shaped strip and the second arc-shaped strip are close to each other, and a limiting tooth groove is provided on the side where the two arc-shaped protrusions are close to each other and located on the outer side of the arc of the first arc-shaped strip and the second arc-shaped strip.

Through the above technical solution, the arc-shaped protrusion is used to cooperate with the connecting portion to achieve axial movement limitation of the connecting portion.

As a further improvement of the above solution, the transverse limiting portion and the connecting portion are an integrally formed structure, and a limiting protrusion that cooperates with the limiting tooth groove is provided on the side away from the two transverse limiting portions.

Through the above technical solution, the limiting tooth groove and the limiting protrusion cooperate to limit the lateral movement between the connecting part and the supporting component.

As a further improvement of the above solution, the limiting tooth grooves are distributed in an equiangular array along the surface of the arc-shaped protrusion, and at least two limiting protrusions are provided on a single transverse limiting portion.

Through the above technical solution, the evenly distributed limiting teeth and grooves are used for the connecting portion to perform limited cooperation at any position between the first arc strip and the second arc strip.

As a further improvement of the above solution, the transverse limiting portion and the connecting portion are arranged at an angle, and the transverse limiting portion is an elastic component with a certain elastic force.

Through the above technical solution, the lateral limiting part pops up at an angle away from its connecting end in the direction deviating from the connecting part, so that the limiting protrusion on its surface has a tendency to get stuck into the limiting tooth groove, and a certain elastic structure (PE or PP material can be used) can quickly release the limitation when kneading, thereby facilitating the position adjustment operation.

As a further improvement of the above solution, an arcuate groove matching the arcuate protrusion is provided on the surface of the connecting portion and at the connection between the connecting portion and the transverse limiting portion, and the first arcuate strip and the second arcuate strip are parallel to each other.

Through the above technical solution, the arc groove and the arc protrusion cooperate to achieve the connection limit between the connecting part and the supporting component.

The supporting component 1 includes a C-shaped portion 11 and a first arc-shaped strip 12 and a second arc-shaped strip 13 respectively arranged at the two ends of the C-shaped portion 11. The first arc-shaped strip 12 and the second arc-shaped strip 13 are both provided with an arc-shaped protrusion 15 on the side close to each other. A limiting tooth groove 16 is provided on the side close to the two arc-shaped protrusions 15 and located on the arc-shaped outer side of the first arc-shaped strip 12 and the second arc-shaped strip 13. The limiting tooth groove 16 is distributed in an array at equal angles along the surface of the arc-shaped protrusion 15, and at least two limiting protrusions 24 are provided on a single transverse limiting portion 22. A tooth groove 14 is provided on the side away from the first arc-shaped strip 12 and the second arc-shaped strip 13. The tooth groove 14 is used to wear the device through the teeth. The cannula fixing component 2 is used, and the cannula fixing component 2 is arranged between the side where the first arc strip 12 and the second arc strip 13 are close to each other. The cannula fixing component 2 includes a connecting portion 21 and two transverse limiting portions 22 arranged on the upper and lower sides of one end of the connecting portion 21. An arc groove 25 adapted to the arc protrusion 15 is arranged on the surface of the connecting portion 21 and at the connection between the connecting portion 21 and the transverse limiting portion 22. The first arc strip 12 and the second arc strip 13 are parallel to each other. The transverse limiting portion 22 and the connecting portion 21 are an integrally formed structure, and the two transverse limiting portions 22 are arranged on the side away from each other with a limiting protrusion 24 matched with the limiting tooth groove 16. The transverse limiting portion 22 is arranged at an angle with the connecting portion 21, and the transverse limiting portion 22 is an elastic component with a certain elastic force. The connecting portion 21 is in a rectangular shape, and a tube clamping groove 23 is arranged on one side of the connecting portion 21.

The implementation principle of an endotracheal tube fixer with adjustable oral position in the embodiment of the present application is as follows: when in use, first align the arc groove 25 on the tube fixing component 2 with the spacing between the two arc-shaped protrusions 15 and insert it, then insert the support component 1 into the patient's mouth, and use the teeth to bite into the tooth grooves 14 on the first arc-shaped strip 12 and the second arc-shaped strip 13 to achieve fixation of the support component 1 in the oral cavity. After the endotracheal tube is inserted, the part to be fixed is inserted into the tube clamping groove 23 on the connecting part 2. When the position needs to be adjusted, the two horizontal limiting parts 22 are pinched to make the limiting protrusion 24 disengage from the limiting tooth groove 16, so that the position of the connecting part 2 in the support component 1 can be freely adjusted, that is, the fixed position of the endotracheal tube can be adjusted.

The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
