Description

Technical Field

[0001] The utility model relates to the technical field of fixing clamps, in particular to a hemodialysis catheter adjustment fixing clamp. Background Art

[0002] The hemodialysis catheter adjustment and fixing clamp is a device for fixing the hemodialysis catheter. The fixing clamp mainly includes a catheter trunk, a three-way seat, a return blood vessel, a drainage blood vessel and a clamping fixture. The return blood vessel and the drainage blood vessel are connected to the catheter trunk through the three-way seat. The clamping fixture is used to clamp and adjust the angle of the three-way seat. When performing hemodialysis, the three-way seat is clamped into the installation groove for clamping and fixing. At the same time, the cylindrical adjustment piece can be rotated. When the cylindrical adjustment piece rotates in the outer ring sleeve, it can drive the three-way seat and the entire catheter to rotate, thereby adjusting the direction of the blood drainage cavity opening. After the angle is adjusted, it can be fixed by the cooperation between the cylindrical adjustment piece and the outer ring sleeve;

[0003] Before installing the fixing clip, first wipe the fixing part, place the fixing pad, install the suture hole on the catheter fixing wing on the pillar, and lock the fixing pad and the catheter through the fixer. However, the fixer and the pillar are small in size, and it is difficult to manually adjust the position of the pillar and the fixing pad. It is necessary to adjust the engagement of the pillar and the fixing pad multiple times. For this reason, we propose a hemodialysis catheter adjustment fixing clip. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-4 The utility model provides a technical solution: a hemodialysis catheter adjustment fixing clamp, comprising: a fixing pad 1, a fixing wing 2 is arranged on the top of the fixing pad 1, and side wings 3 are fixed on both sides of the fixing wing 2, and suture holes 4 are opened inside the side wings 3;

[0025] It also includes: a limiting component 5, which is arranged on both sides of the fixing pad 1, and the suture hole 4 is limited by the limiting component 5 to achieve rapid and accurate docking of the fixing wing 2 and the fixing pad 1;

[0026] The fixing component 6 is arranged on the side of the side wing 3. When the side wing 3 is pressed against the surface of the fixing component 6, the side wing 3 is clamped and limited by the fixing component 6 to achieve stable installation of the side wing 3. The position of the fixing pad 1 and the fixed wing 2 is limited by the limiting component 5 to prevent the fixed wing 2 from moving laterally on the surface of the fixing pad 1. When the side wing 3 moves downward, the side wing 3 is clamped and limited by the fixing component 6 at the same time, so that the installation of the fixed wing 2 is more stable.

[0027] The limiting assembly 5 includes a guide ring 51 inserted into the suture hole 4, and a clamping ring 52 is fixed to the bottom of the guide ring 51. The diameter of the top of the guide ring 51 is smaller than the diameter of the bottom of the guide ring 51. Through the design of the guide ring 51, the guide ring 51 is guided to be inserted into the suture hole 4, which is beneficial for the guide ring 51 to be inserted into the suture hole 4, thereby limiting the suture hole 4. The operator does not need to adjust the position of the fixed wing 2 multiple times, which is beneficial for the accurate docking of the fixed wing 2 with the fixed pad 1.

[0028] A connecting block 53 is fixed to the side of the bottom of the retaining ring 52, and a compression spring 54 is fixed to the side of the connecting block 53. A storage cavity 55 cooperating with the connecting block 53 is opened inside the fixing pad 1, and the compression spring 54 is fixed to the inner wall of the storage cavity 55 on the side away from the connecting block 53. When the guide ring 51 is pressed against the bottom of the suture hole 4, the surface of the guide ring 51 squeezes the inner wall of the suture hole 4. When the fixed wing 2 moves downward, the suture hole 4 squeezes the guide ring 51 and pushes the guide ring 51 away from the fixed wing 2. At this time, the compression spring 54 is in a compressed and force-storing state. This design is conducive to adjusting the docking position of the guide ring 51 and the suture hole 4. At the same time, the pressure of the compression spring 54 makes the insertion of the suture hole 4 and the guide ring 51 more stable.

[0029] Embodiment 2

[0030] See also Figure 5-6 The fixing assembly 6 includes a pressing plate 61 pressed by the side wing 3, and a connecting plate 62 is fixed to the side of the pressing plate 61, and a clamping block 63 is fixed to the top of the side of the connecting plate 62. When the side wing 3 moves downward, the bottom of the side wing 3 presses against the surface of the pressing plate 61, and the side wing 3 presses against the pressing plate 61 and pushes the pressing plate 61 to rotate downward, and the pressing plate 61 drives the connecting plate 62 and the clamping block 63 to rotate synchronously until the clamping block 63 presses against the surface of the side wing 3, thereby realizing the limited fixing operation of the placement of the side wing 3. Through this design, it is easy to realize the fixing of the installation of the side wing 3, and there is no need to manually operate the fixer to clamp the side wing 3, which is more convenient.

[0031] A rotating shaft 64 is fixed to one side of the connecting plate 62 close to the fixed pad 1, and the rotating shaft 64 is movably connected to the connecting seat 65 through a movable shaft. The bottom of the connecting seat 65 is fixed to the surface of the fixed pad 1, and a torsion spring 66 is sleeved on the outside of the movable shaft. One end of the torsion spring 66 is fixed to the surface of the rotating shaft 64, and the other end of the torsion spring 66 is pressed against the surface of the fixed pad 1. The rotation of the rotating shaft 64 is limited by the torsion spring 66. When the side wing 3 moves downward and the pressing plate 61 is pressed, the torsion spring 66 is in a compressed and force-storing state, thereby clamping and limiting the side wing 3 and maintaining the stability of the installation of the fixed wing 2.

[0032] The bottom side of the card block 63 away from the side wing 3 is set to an inclined shape, and the top side of the side wing 3 away from the fixed wing 2 is provided with a card slot that cooperates with the card block 63. Through the above design, it is convenient for the card block 63 to be engaged into the inside of the card slot, so that the engagement between the card block 63 and the card slot is more stable.
