DETAILED DESCRIPTION

[0025] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Example

[0026] The anti-breakage cannula fixing device described in this embodiment is as follows: Figure 1 and Figure 5 As shown, it includes a fixing plate 1, and a protective cover 3 for the patient to bite is provided on the rear side wall of the fixing plate 1, which is convenient for fixing and prevents the patient from biting the catheter;

[0027] Two clamping blocks 2 are provided on the top of the fixing plate 1 for clamping on the left and right sides, and the clamping blocks 2 are provided with limiting components for fixing them on the fixing plate 1, so that the inserted catheter can be fixed through the clamping blocks 2 to prevent the shaking of the catheter from causing damage to the patient's throat;

[0028] The clamping block 2 is provided with an adjustment component for clamping catheters of different sizes on the opposite side walls, and the clamping block 2 is provided with a locking component for fixing the catheter between the two clamping blocks 2, so as to facilitate the fixing of catheters of different sizes, thereby improving the applicability, achieving a better fixing effect and reducing the use cost;

[0029] The fixing plate 1 is provided with fixing belts 4 on both sides for fixing it to the patient's face, so as to facilitate fixing the fixing plate 1 to the patient's face, thereby facilitating the fixing of the catheter and subsequent operations;

[0030] One end of the two fixing straps 4 is fixed to the left and right sides of the fixing plate 1, and the movable ends thereof are connected with Velcro to facilitate fixation while reducing the discomfort of the patient.

[0031] The clamping surface of the clamp block 2 is provided with a groove for fixing the catheter, and the groove is in a semicircular structure, which facilitates a higher degree of fit with the catheter, thereby achieving a better clamping and fixing effect, making the position of the catheter more stable, and avoiding shaking to cause damage to the patient's throat;

[0032] An anti-slip layer may also be provided in the groove to further increase the stability of the clamping and reduce the pressure on the catheter, thereby avoiding damage to the catheter caused by excessive clamping. Example

[0033] This embodiment further illustrates the technology. Figure 3 and Figure 4 As shown, the two clamping plates 13 are matched with each other for left and right clamping, and the outer ends of the clamping plates 13 are horizontally fixed with connecting rods 12, and the bottom of the groove is provided with a slot for inserting the connecting rod 12, and a baffle 11 is vertically arranged on the connecting rod 12 in the slot, and a fixing block for preventing the baffle 11 from falling off is arranged at the slot notch, and a first spring 10 is arranged between the baffle 11 and the bottom of the slot; this paragraph of text as a whole constitutes an adjustment component for clamping catheters of different sizes, which is convenient for clamping catheters of different sizes, thereby improving applicability and reducing the cost of use to a certain extent.

[0034] The clamping plate 13 is in a "C" shape as a whole, and the inner arc amplitude of the groove is smaller than the arc amplitude of the clamping plate 13, so that catheters of different sizes can be well fitted, thereby achieving a better clamping effect.

[0035] like Figure 6 and Figure 7 As shown, a mounting groove for inserting a clamp 13 is provided at the bottom of the groove. When the first spring 10 is in the maximum compression state, the clamp 13 is located in the mounting groove, and the clamping surface of the clamp 13 is located at the same horizontal plane as the wall of the groove, so that a large-sized catheter can be clamped by the clamp block 2, thereby avoiding the clamp 13 from affecting the clamping effect, thereby improving the clamping stability. Example

[0036] This embodiment further illustrates the technology. Figure 1 and Figure 2 As shown, the limit assembly includes a limit rod 7, a through hole which is vertically opened on the clamp 2 and communicates with each other up and down, the limit rod 7 is independently installed in the through hole, a support plate is horizontally fixed on the limit rod 7 located in the through hole, and a stopper 8 for preventing the support plate from falling off upward is fixed on the top of the through hole, and a second spring 9 is mounted on the limit rod 7 between the stopper 8 and the support plate. In the natural state, the bottom of the limit rod 7 is tightly fitted with the top of the fixing plate 1, so that the catheter can be clamped by the clamp 2 and fixed after the position is adjusted, so as to avoid shaking of the catheter position during use and causing damage to the patient's throat.

[0037] The limiting rod 7 is in the shape of a letter "7" as a whole, and one horizontal end thereof is located outside the top of the through hole, which is convenient for preventing the limiting rod 7 from falling into the through hole and for lifting the limiting rod 7, thereby facilitating the clamping block 2 to slide left and right for limiting. Example

[0038] This embodiment further illustrates the technology. Figure 1 , Figure 6 and Figure 7 As shown, the locking assembly includes an insert block 14, which is horizontally fixed on the clamping surface of one of the clamping blocks 2, and the clamping surface of the other clamping block 2 is provided with a limiting groove that is interference fit with the insert block 14, so that the two clamping blocks 2 can clamp and fix the catheter;

[0039] The locking assembly can also be fixed with Velcro, so that the catheter can be clamped and fixed by the two clamping blocks 2.

[0040] The two clamping blocks 2 are slidably matched with the fixing plate 1 left and right. A sliding groove is horizontally opened on the top of the fixing plate 1, and a fixing rod 6 is horizontally fixed in the sliding groove. Two sliding sleeves 5 are mounted on the fixing rod 6 and slidably matched with it left and right. The two sliding sleeves 5 are respectively fixed to the bottoms of the two clamping blocks 2, so that the fixing position of the catheter can be adjusted according to different needs, and the position of the catheter can be moved to clean the patient's oral cavity.

[0041] like Figure 1 and Figure 5 As shown, the protective cover 3 is made of elastic material, which is convenient for the patient to bite and also allows the patient to move the mouth slightly, thereby relieving discomfort and improving comfort during use.

[0042] The rear side wall of the fixing plate 1 is provided with a placement groove for being mounted on the patient's lower jaw. The placement groove is not shown in the figure. It facilitates the fixation of the fixing plate 1 to be more stable. At the same time, it reduces the movement range of the catheter to a certain extent, and when the patient's mouth moves, it will drive the catheter to move at the same time, thereby reducing the wear of the catheter on the patient's throat.
