[0029] Further, two installation grooves 4 are respectively provided with limiting members 40 for limiting the catheter in the channel on the opposite side.

[0030] The working principle of the utility model is:

[0031] As an embodiment 1, the catheter of the application takes a urinary catheter as an example to illustrate the design concept of the application, Figure 1 For the state that the elastic structure of the upper cover 3 is clamped in the clamping groove 5 on the catheter fixing seat 2, it can be seen from the figure that the installation groove 4 opened in the upper cover 3 and the installation groove 4 opened in the catheter fixing seat 2 are jointly surrounded to form a channel for the urinary catheter to pass through, and the shape of the installation groove 4 can be customized according to the shape of the catheter to be limited. When the catheter needs to be limited, place the catheter in the installation groove 4 on the catheter fixing seat 2, press the pressing block 62 in the horizontal direction, because the pressing block 62 is integrally formed with the U-shaped piece 61, and the elastic structure itself has a certain elasticity, so when pressing, the U-shaped piece 61 can be extruded to deform, then press the lower end of the U-shaped piece 61 into the clamping groove 5 (at this time the U-shaped piece 61 can move in the clamping groove 5) at the same time, remove the force on the pressing block 62, and the U-shaped piece 61 will recover the deformation due to the elastic property. Finally, the U-shaped piece 61 is clamped in the clamping groove 5.

[0032] In the above technical solution, in order to further strengthen the connection strength between the U-shaped piece 61 and the clamping groove 5, the application further provides an abutting block on the U-shaped piece 61, and a limiting table 8 is arranged in the clamping groove 5, that is, the U-shaped piece 61 is moved downward at the same time as the pressing block 62 is pressed, and the abutting block is moved into the clamping groove 5 together with the U-shaped piece 61, at this time the force on the pressing block 62 is removed, and the U-shaped piece 61 recovers the deformation at the same time as the abutting part 7 abuts against the limiting table 8. When the upper cover 3 needs to be opened, press the pressing block 62 in the horizontal direction to make the U-shaped piece 61 deform, at this time the U-shaped piece 61 drives the abutting part 7 to move away from the limiting table 8, and the elastic structure is lifted upward at the same time as the pressing block 62 is pressed, and the upper cover 3 rotates relative to the catheter fixing seat 2, and finally the elastic structure is disconnected with the clamping groove 5.

[0033] On the basis of the above technical solution, the application further connects a plug column 31 on the upper cover 3, and a plug hole 20 is arranged on the catheter fixing seat 2, that is, when the upper cover 3 is clamped on the clamping groove 5 of the catheter fixing seat 2 through the elastic structure, the plug column 31 will be inserted and matched with the plug hole 20, further improving the connection strength between the upper cover 3 and the catheter fixing seat 2.

[0034] On the basis of the above technical solution, considering that the urinary catheter is generally a soft tube material, in order to enhance the limiting effect on the urinary catheter, the application provides a limiting member 40 in each installation groove 4, which can abut against the urinary catheter through the limiting member 40, thereby enhancing the limiting effect on the urinary catheter.

[0035] In the catheter fixing device use scenario of the present application, it is generally necessary to fix the catheter fixing device on the body surface with the aid of the body surface fixing part 1. The body surface fixing part 1 can be adhered to the skin by using a fixing patch (the fixing patch is not shown in the figure), and then a positioning seat 11 is arranged on the fixing patch, and the catheter fixing seat 2 is rotationally arranged on the positioning seat 11. In this way, the catheter can be better pulled to the specified position. Since the body surface fixing part belongs to a mature technical means in the technical field, its working principle will not be described here.

[0036] The catheter fixing device of the present application is provided with an elastic structure on the upper cover 3, and a clamping groove 5 matched with the elastic structure is arranged on the catheter fixing seat 2. In this way, the connection strength between the upper cover 3 and the catheter fixing seat 2 can be enhanced, and the problem of decoupling between the upper cover 3 and the catheter fixing seat 2 can be effectively prevented.

[0037] Although the present application is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the disclosure that various changes or modifications can be made to the present application without departing from the principles and spirit of the application defined in the claims. Therefore, the detailed description of the present application is only used to explain, but not to limit the present application, and the protection scope is defined by the content of the claims.
