Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a catheter fixator. Background Technique

[0002] Neurosurgery is a branch of surgery. Based on surgery as the main treatment method, it applies unique neurosurgical research methods to study the human nervous system. Catheters are required in neurosurgical operations. However, at present, the catheter fixation work is skin suture fixation and tape fixation, which is relatively complex and troublesome, and problems are likely to occur.

[0003] After retrieval, the publication number is CN209630398U, which discloses a catheter device for neurosurgery, including a rubber block. The rubber block is in an "丄"-shaped ring structure, and a vertical through hole is provided on the rubber block. A medical catheter is inserted through the vertical through hole. A horizontal through hole is provided on one side of the rubber block. A movable bracket is provided at the front end of the horizontal through hole. The front end of the horizontal through hole is provided with a threaded structure, and a movable rod is inserted through the threaded structure. An adhesion pad is provided at the lower end of the rubber block. The adhesion pad is made of medical polypropylene and is adhesively fixed to the skin through medical pressure-sensitive adhesive.

[0004] In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. The movable rod rotates in the horizontal threaded through hole of the rubber block and interacts with it, so that the bracket squeezes and fixes the medical catheter inserted into the vertical through hole of the rubber block. However, in the use process, the extrusion force of the rubber block on the catheter cannot be controlled, which is likely to cause too large an extrusion force, resulting in serious deformation of the catheter and affecting the normal use of the catheter. If the extrusion force is too small, the catheter is likely to loosen.

[0005] Therefore, we propose a catheter fixator that can solve the above problems. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a catheter fixator to solve the problems raised in the background technique.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: A catheter fixator includes a fixed seat. A positioning groove is horizontally penetrated through the middle of the upper surface of the fixed seat. Two groups of rubber blocks are movably connected inside the positioning groove. It also includes a guide angle and a limiting groove. The guide angle is opened at one end of the upper surface of the rubber block, and the limiting groove is opened at one end of the lower surface of the rubber block. Adjusting grooves are symmetrically opened on the inner walls of both sides of the positioning groove. The adjusting grooves are slidably connected with the rubber blocks. One end of the rubber block placed inside the adjusting groove is provided with a spring. A double-sided sticker is bonded to the bottom side of the fixed seat, and the double-sided sticker matches the size of the fixed seat.

[0008] As an optional solution of the technical solution of the present application, the guide angle is at an angle of 45 degrees to the horizontal direction, and the limiting groove is arc-shaped.

[0009] As an optional solution of the technical solution of the present application, a connecting groove is horizontally opened at one end of the rubber block placed inside the adjustment groove, and a connecting rod is horizontally fixedly installed on the inner wall of one side of the adjustment groove, and the connecting rod is slidably connected to the connecting groove.

[0010] As an optional solution of the technical solution of the present application, the spring is sleeved on the outside of the connecting rod, and the size of the spring matches that of the connecting groove.

[0011] As an optional solution of the technical solution of the present application, the two groups of rubber blocks are symmetrically arranged, and the adjustment grooves are matched with the sizes of the rubber blocks.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: through the guide angle opened on the upper surface of the rubber block, it is convenient to push the two groups of rubber blocks to move in opposite directions, so that the catheter is inserted into the inner side of the positioning groove and placed on the bottom side of the two groups of rubber blocks; through the combination of the adjustment groove and the spring, the elastic force of the spring can push the two groups of rubber blocks to move relative to each other in the positioning groove; through the limit groove on the bottom side of the rubber block, the catheters of different sizes at the bottom end of the positioning groove can be effectively limited and clamped, which is convenient and quick.

[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a catheter holder, including a fixing seat 1, a positioning groove 11 is horizontally penetrated in the middle of the upper surface of the fixing seat 1, two groups of rubber blocks 12 are movably connected on the inner side of the positioning groove 11, and also includes a chamfer 15 and a limiting groove 16, the chamfer 15 is opened at one end of the upper surface of the rubber block 12, the limiting groove 16 is opened at one end of the lower surface of the rubber block 12, the chamfer 15 is at an angle of 45 degrees to the horizontal direction, the limiting groove 16 is arc-shaped, and the inner walls on both sides of the positioning groove 11 are symmetrically provided with adjustment grooves 13, the adjustment groove 13 is slidably connected to the rubber block 12, and a spring 14 is arranged on one end of the rubber block 12 placed inside the adjustment groove 13.

[0018] In this technical solution, the chamfer 15 provided on the upper surface of the rubber block 12 facilitates the two groups of rubber blocks 12 to move in opposite directions, so that the catheter is inserted into the inner side of the positioning groove 11 and is placed on the bottom side of the two groups of rubber blocks 12. By combining the adjustment groove 13 and the spring 14, the elastic force of the spring 14 can push the two groups of rubber blocks 12 to move relative to each other in the positioning groove 11. Through the limiting groove 16 on the bottom side of the rubber block 12, catheters of different sizes at the bottom end of the positioning groove 11 can be effectively limited and clamped, which is convenient and quick.

[0019] In this embodiment, a connecting groove 2 is horizontally opened at one end of the rubber block 12 placed inside the adjusting groove 13, a connecting rod 21 is horizontally fixedly installed on the inner wall of one side of the adjusting groove 13, the connecting rod 21 is slidably connected to the connecting groove 2, the spring 14 is sleeved on the outside of the connecting rod 21, the size of the spring 14 matches the size of the connecting groove 2, the two groups of rubber blocks 12 are symmetrically arranged, and the size of the adjusting groove 13 matches the size of the rubber block 12.

[0020] In this technical solution, the connecting rod 21 is slidably connected to the connecting groove 2, so that the movement stability of the rubber block 12 can be improved. At the same time, the connecting rod 21 can limit the spring 14 to prevent the spring 14 from tilting during compression and extension, which affects the use effect of the rubber block 12.

[0021] In this embodiment, a double-sided sticker 17 is bonded to the bottom side of the fixing seat 1 , and the double-sided sticker 17 matches the size of the fixing seat 1 .

[0022] In this technical solution, the double-sided sticker 17 on the bottom side of the fixing base 1 facilitates the fixing base 1 to be attached to a designated position on the patient's skin.
