Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical auxiliary tools, and particularly relates to an endotracheal tube intraoral fixator. BACKGROUND

[0002] In the tracheal intubation general anesthesia, the safe fixation and non-falling of the endotracheal tube is very important for the operation. At present, most of the clinical methods are to fix the endotracheal tube outside the cheek of the surgical patient in the form of "8" by using adhesive tape, or to fix it by using a head and neck band.

[0003] The adhesive tape winding method is a commonly used method for anesthesiologists in their work. After being soaked by saliva, disinfectant, blood and other liquids, the adhesive tape will lose its adhesion, and its firmness will be greatly reduced, which will cause the endotracheal tube to move outward or fall off, making the patient very unsafe. In addition, for patients undergoing facial surgery, the adhesive tape winding method will affect disinfection and operation. At present, most doctors use needle and thread to sew on the lips or gums, which will increase the postoperative pain and anxiety of the patient, etc. SUMMARY

[0004] In view of this, in order to solve the above-mentioned problems existing in the prior art, the purpose of the present application is to provide an endotracheal tube intraoral fixator to achieve the stability of the fixation of the endotracheal tube in the patient's oral cavity, and to be suitable for different surgical positions and to reduce the difficulty of surgical operation.

[0036] Embodiment 1

[0037] As shown in the drawings, in the present embodiment, a tracheal tube intraoral fixator is specifically provided, which aims to replace the existing adhesive fixing method by the fixator to ensure that the fixation of the tracheal tube 6 in the patient's mouth 7 is more stable and is not affected by external factors. Figures 1-3

[0038] ​The fixing device comprises a fixing tube body 1 and two sets of gasket pairs arranged on the fixing tube body 1. In actual application, the fixing tube body 1 is inserted into the oral cavity 7, and therefore, one end of the fixing tube body 1 is provided in a semi-open shape. The medical staff inserts the fixing tube body 1 into the oral cavity 7 of the patient through the end, and meanwhile, the end of the fixing tube body 1 can avoid causing discomfort to the patient. The inner hole of the fixing tube body 1 is matched with the tracheal tube 6, and the tracheal tube 6 can be inserted into the oral cavity 7 of the patient along the inner hole of the fixing tube body 1. In order to ensure the stability of the tracheal tube 6 on the fixing tube body 1, a fixing clamp 8 is arranged at one end of the fixing tube body 1, and the tracheal tube 6 is fixed in the fixing tube body 1 through the fixing clamp 8. Considering the manufacturing cost of the fixing device, the fixing clamp 8 is provided as a fixing ring with an opening. The fixing ring is integrally formed on the tracheal tube 6, and the material of the fixing ring is made of elastic plastic. The opening of the fixing ring is provided with toothed openings that are mutually engaged. Since the fixing ring is provided with an opening, the fixing ring can be deformed under the action of an external force. In the deformation process, the toothed openings at two ends of the opening can be mutually engaged, so as to change the inner diameter of the fixing ring, and the tracheal tube 6 can be firmly fixed under the action of the fixing ring.

[0039] After the fixing tube body 1 is inserted into the oral cavity 7 of the patient, it needs to be fixed to replace the existing "8" adhesive tape fixing mode. Therefore, two sets of gasket pairs are arranged on the fixing tube body 1. The two sets of gasket pairs are symmetrically arranged and correspond to the tooth rows of the upper oral cavity 7 and the lower oral cavity 7, so as to achieve good fixation of the fixing tube body 1. The gasket pairs are movably assembled on the fixing tube body 1 and are clamped on the tooth rows in the oral cavity 7, so as to fix the fixing tube body 1 in the oral cavity 7 through the gasket pairs.

[0040] The gasket pairs are designed as follows: one end of the gasket pairs is movably assembled on the outer wall of the fixing tube body 1 through a limiting assembly. The gasket pairs can freely slide along the axial direction of the fixing tube body 1, so as to adapt to different fixing positions. In clinical practice, in order to ensure that the gasket pairs have good fixing effect, the axial direction and the circumferential direction of the gasket pairs on the fixing tube body 1 should have adjustable margins. Therefore, the gasket pairs are designed as follows:

[0041] Each of the gasket pairs comprises an outer gasket 2 and an inner gasket 3, which are located on the same side of the fixed tube body 1 (with the center line of the fixed tube body 1 as the center plane, such as being located on the upper side of the center plane or being located on the lower side of the center plane), and one end of the outer gasket 2 and the inner gasket 3 is movably assembled on the outer wall of the fixed tube body 1 through a limiting assembly, and is clamped on the tooth row in the oral cavity 7 through the outer gasket 2 and the inner gasket 3. Under the action of the limiting assembly, the outer gasket 2 and / or the inner gasket 3 can be fixed in any axial direction of the fixed tube body 1, and at the same time, after being fixed in the current position, the outer gasket 2 and / or the inner gasket 3 can be rotated in a certain range along the circumferential direction of the fixed tube body 1, so that through the adjustment in the above two dimensions, the gasket pair on the fixed tube body 1 can adapt to different positions and different shapes of the teeth in the oral cavity 7. In actual application, the limiting assembly comprises a sliding groove 4 and a clamping opening on the gasket pair, wherein the sliding groove 4 is provided with two and is symmetrically provided on both sides of the fixed tube body 1, and a plurality of strip-shaped grooves 5 are arranged in the sliding groove 4 in the axial direction of the fixed tube body 1, the spacing between the adjacent two strip-shaped grooves 5 should be slightly smaller than the thickness of the teeth in the oral cavity 7, and each of the strip-shaped grooves 5 is located in the circumferential direction of the outer wall of the fixed tube body 1, so as to satisfy the outer gasket 2 and the inner gasket 3 with a certain range of adjustment in the circumferential direction of the fixed tube body 1.

[0042] As shown in Figure 5 The one end of the outer gasket 2 and the inner gasket 3 is provided with a clamping opening, which is matched with the outer wall of the fixed tube body 1, and the opposite sides of the clamping opening are provided with limiting blocks 9 matched with the strip-shaped grooves 5, and the limiting blocks 9 are arc convex spherical. The limiting blocks 9 are provided in the form of arc convex spherical, which can ensure that the outer gasket 2 and the inner gasket 3 can slide between each strip-shaped groove 5 in the sliding groove 4, and since the clamping opening itself has a certain elastic force after being provided on the outer gasket 2 and the inner gasket 3, the limiting blocks 9 on the two sides of the clamping opening will be clamped into the strip-shaped grooves 5 under the action of the elastic force, and since the limiting blocks 9 are in the form of arc convex spherical, the outer gasket 2 and the inner gasket 3 can be adjusted by rotating in the circumferential direction of the fixed tube body 1, so as to adapt to the teeth in different directions in the oral cavity 7 of the patient.

[0043] In order to further improve the fixing degree of the fixer in the oral cavity of the patient, the outer gasket 2 and the inner gasket 3 are provided with anti-skid pieces 12 on the side surface facing the teeth, the anti-skid pieces 12 are slightly convex compared with the surface of the gasket, and at the same time, the anti-skid pieces 12 are made of anti-skid rubber, which has a large friction force and has a good anti-skid effect when being attached to the surface of the teeth in the oral cavity, thereby further improving the firmness between the gasket and the teeth.

[0044] Example 2

[0045] On the basis of the endotracheal tube oral cavity fixer provided in Example 1,Figure 4 As shown, the outer gasket 2 and the inner gasket 3 are sleeved with a fixing sleeve rope 10, and one end of the fixing sleeve rope 10 is led out to the outside of the oral cavity 7 through the lead hole 11 on the outer wall of the fixed tube body 1. In actual application, the fixing sleeve rope 10 is arranged only on the inner gasket 3, which can achieve the effect of auxiliary fixing, and is also convenient for disassembly later. Specifically, the fixing sleeve rope 10 can be made of soft material, and the soft material has certain plasticity. Therefore, the fixing sleeve rope 10 can be firmly sleeved on the teeth in the oral cavity 7 through the tooth gap, and the fixing sleeve rope 10 is knotted in the form of an eight-character knot, and the end after knotting is led out to the outside of the oral cavity 7. After the medical staff adjusts the position and orientation of the outer gasket 2 and the inner gasket 3, the end of the rope led out is pulled, and under the action of the eight-character knot, the gasket pair can be firmly fixed on the teeth in the oral cavity 7, so as to further assist in fixing the fixed tube body 1, so as to improve the stability and reliability of the fixed tube body 1. In actual application, in order to ensure the stable rope wiring of the fixing sleeve rope 10 pulled, the lead hole 11 is arranged on the outer wall of the fixed tube body 1, and one end of the fixing sleeve rope 10 is led out through the lead hole 11, so as to facilitate the medical staff to pull the end part, and then assist in fixing, thereby improving the firmness of the fixed tube body 1.

[0046] The present application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solutions falling within the scope defined by the claims of the present application fall within the protection scope of the present application.
