[0021] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, rather than being construed as a limitation to the technical solutions of the present invention.

[0022] As Figures 1 to 4As shown in the figure, the present invention provides a catheter fixing device, including a base 1. The base 1 of the present application is a cuboid structure as a whole. In other embodiments of the present application, in order to fit the human body, a certain arc may be provided on the lower surface of the base to match the corresponding part of the human body. The base of the present application is prepared from organic materials harmless to the human body, and the base as a whole maintains a certain hardness and at the same time should also have a certain flexibility to improve the comfort of use. Specifically, regarding the materials used, the present application does not limit this, because there are many types of materials that can meet the above conditions for the preparation of the base. Those skilled in the art or manufacturers can select the materials according to their needs for processing.

[0023] Regarding the preparation of the base 1 of the present application, conventional injection molding, blow molding and other methods can be used for processing to achieve the purpose. Of course, those skilled in the art can also use any other processing methods according to the knowledge they have mastered, which will not affect the implementation of the technical solution of the present application. Here, the applicant gives an example of the base. For example, the length of the base is 2.5 cm, the width is 1.0 cm, and the height is 1.5 cm. It should be noted that this is only an example, and it does not mean that the base of the present application can only use this size. In fact, those skilled in the art can select any suitable size according to the different parts used.

[0024] An open slideway 6 is provided on the upper surface of the base 1. The cross-section of the open slideway 6 of the present application is convex-shaped, as Figure 2 shown. Such a structure can prevent the catheter fixing block 2 from coming out of the base. Two catheter fixing blocks 2 are slidably arranged in the open slideway 6. The structures and specifications of the two catheter fixing blocks of the present application are the same, and their overall shapes are also convex-shaped to match the open slideway of the base. In the technical solution of the present application, the assembly of the catheter fixing block 2 and the open slideway 6 can be completed at one time during the process of processing the base, or the catheter fixing block can be placed in the open slideway by applying an external force later. Because the overall structure of this device is not large and is made of non-metallic materials with a certain elasticity, the catheter fixing block can be inserted into the open slideway by an external force. In other embodiments of the present application, those skilled in the art can also use other methods to place the catheter fixing block in the open slideway.

[0025] In this application, a side wall 3 is provided on the upper surface of the base at both ends of the open slideway 6. One end of the protective cap 4 is hingedly connected to one of the side walls, and the other end of the protective cap is snap-connected to the other side wall. In other embodiments of this application, the protective cap can also be snap-connected to both side walls. Its main function is to prevent the catheter from slipping out between the two catheter fixing blocks. Specifically, the snap-connection method is a conventional technology. Here, the applicant will not elaborate on the snap-connection method. Those skilled in the art can select a conventional snap-connection method according to their needs to implement the technical solution of this application.

[0026] A glue layer 5 is provided on the lower surface of the base 1 of this application. The glue layer is an easily removable glue with strong fixing force. Of course, a protective layer is also included outside the glue layer to protect the glue layer. When in use, the protective layer is torn off to expose the glue layer. This application does not limit the glue. Those skilled in the art can obtain it through commercial channels according to existing glue varieties.

[0027] In this application, the cross-section of the open slideway 6 is convex-shaped. Tooth-shaped structures are provided on the two opposite inner side walls of the upper part of the convex shape, and the two opposite inner side walls of the lower part of the convex shape are smooth surfaces without tooth-shaped structures. Tooth-shaped structures are provided on the side walls where the two catheter fixing blocks contact the open slideway, for cooperation with the tooth-shaped structures of the open slideway. Thus, when the two catheter fixing blocks are adjusted to the set position, they will not move without applying external force, so as to avoid excessive gaps and the catheter moving in the gaps.

[0028] In this application, the overall shape of the catheter fixing block 2 is convex-shaped to cooperate with the open slideway. Vertical tooth groove structures are provided on the sides where the two catheter fixing blocks contact the catheter. The tooth height of the tooth-shaped structure is greater than the tooth height of the vertical tooth groove structure, and the width between two adjacent teeth of the vertical tooth groove is less than the width between two adjacent teeth of the tooth-shaped structure. The vertical tooth groove structure can have a certain clamping effect on the passing catheter, rather than passing through a smooth surface, thereby reducing the possibility of the catheter moving between the two catheter fixing blocks to a certain extent.

[0029] In this application, in order to further prevent the two catheter fixing blocks from moving after being clamped by the protective cap, for this purpose, a plurality of stop tooth grooves are provided on the upper end surface of the catheter fixing block, and a tooth groove structure matching the stop tooth grooves is provided on the inner surface of the protective cap. In this way, when the protective cap presses the upper end of the catheter fixing block tightly, the stop tooth grooves at the upper end of the catheter fixing block are snap-fitted with the tooth groove structure on the inner surface of the protective cap, thereby achieving the purpose of preventing the catheter fixing block from moving.

[0030] In this application, the protective cap 4 is composed of an inner hard plastic layer 42 and an outer soft silicone layer 41. The tooth groove structure is provided on the inner surface of the hard plastic layer.

[0031] Working principle:

[0032] During use, open the buckle at one end of the protective cap with a side wall, flip the protective cap by a certain angle to expose both catheter fixing blocks, place the catheter to be fixed between the two catheter fixing blocks, then move the two catheter fixing blocks so that the catheter fixing blocks clamp the catheter. After ensuring that the catheter does not deform too much, lock the protective cap and the side wall through the buckle. At this time, in addition to the clamping of the catheter by the two catheter fixing blocks, the two catheter fixing blocks are respectively fixed by the toothed structure on the inner wall of the open slideway of the base and the inner wall of the protective cap to prevent the movement of the catheter fixing blocks, realizing the fixation of the catheter. Then tear off the protective layer under the base and stick the base to a specific position of the patient by pressing.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
