Description

Technical Field

[0001] The utility model relates to the technical field of dialysis catheter brackets, in particular to a dialysis catheter fixing bracket. Background Art

[0002] Dialysis is a treatment used to replace part or all of the kidney function. When the kidneys are unable to effectively filter waste and excess fluid from the blood, dialysis can help maintain normal body function. There are two common types of dialysis: hemodialysis and peritoneal dialysis. A dialysis catheter is a medical device used in hemodialysis treatment. It is usually a flexible tubular structure that is placed in the patient's blood vessels or other appropriate locations to lead the patient's blood out, through the dialyzer, and then returned to the body. The dialysis catheter is designed to provide a reliable, safe, and sterile channel to ensure the effectiveness of dialysis treatment. A dialysis catheter fixation bracket is a device used to fix a dialysis catheter (usually an intravascular dialysis catheter) to ensure that the catheter is stably positioned in the patient's body.

[0003] A Chinese patent document with a search announcement number of CN218774034U discloses a bracket for fixing a dialysis catheter, including a bracket body and a hook, a hook is provided on the outer side of the top end of the bracket body, and a docking sleeve is provided on the outer side of the lower side of the bracket body, the docking sleeve is connected to the bracket body by bolts, and a connecting plate is fixedly connected to one side of the docking sleeve, a fixing mechanism is provided above the connecting plate, and the fixing mechanism includes a limit seat, a movable groove, a limit sleeve, a movable block, a connecting rod, a spring and a limit block. The bracket for fixing the dialysis catheter can loosen the limit sleeve pulled upward, and the loosened limit sleeve can be automatically reset by the elastic force of the spring. The limit sleeve that can be automatically reset is provided, so that the bracket for the dialysis catheter can be convenient for fixing and limiting the dialysis pipeline. The bracket for the dialysis catheter can be used to wind and regularize a long dialysis catheter through two connecting frames provided on the bracket body. During use, the height of the bracket for fixing the dialysis catheter cannot be adjusted according to the height of the bed, which is inconvenient for medical staff to operate, and cannot meet the different postures of patients during fluoroscopy, thereby reducing the practicality of the bracket.

[0025] The base 1 is provided to facilitate the installation of the fixing frame 2. By rotating the turntable 4, the turntable 4 rotates and drives the first bevel gear 6 fixed on the right side of the outside of the rotating rod 5 to rotate. The first bevel gear 6 rotates and drives the screw rod 8 fixed inside the second bevel gear 7 to rotate. The screw rod 8 rotates and drives the mounting frame 12 fixed on both sides of the outside of the adjusting block 9 to move. The height of the fixing bracket can be adjusted according to the height of the bed, which is convenient for medical staff to operate. At the same time, it can also meet the postures of different patients when doing fluoroscopy, thereby improving the practicality of the dialysis catheter fixing bracket. The limiting block 10 is slidably connected to the inside of the limiting groove 11 to play a limiting role.

[0026] Reference Figure 2 and Figure 4 A pull rod 14 is slidably connected inside the mounting frame 12, a pull ring 15 is fixedly connected to the top of the pull rod 14, a first arc-shaped clamping plate 16 is fixedly connected to the bottom of the pull rod 14, a spring 17 is sleeved outside the pull rod 14, a fixing rod 19 is fixedly connected to the bottom of the mounting frame 12, and a second arc-shaped clamping plate 18 is fixedly connected to the top of the fixing rod 19.

[0027] By pulling the pull ring 15 to move the pull rod 14, the pull rod 14 moves the first arc-shaped clamping plate 16 fixed at the bottom, and at the same time, the spring 17 sleeved on the outside of the pull rod 14 is squeezed, and then the dialysis catheter is passed through the upper part of the second arc-shaped clamping plate 18, and then the pull ring 15 is released to fix the dialysis catheter under the reaction force of the spring 17, so that the dialysis catheter is easy to fix, and the catheter is prevented from accidentally moving or falling off during use, and the stability of the dialysis catheter during use is improved.

The stability of the base 1 is improved by fixing the triangular blocks 3 around the base 1.

[0030] Working principle: When the dialysis catheter fixing bracket is used and the height of the bracket needs to be adjusted, the turntable 4 is rotated, and the turntable 4 rotates with the rotating rod 5 fixedly connected to the outside, and the rotating rod 5 rotates with the first bevel gear 6 fixedly connected to the right side of the outside, and the first bevel gear 6 rotates with the second bevel gear 7 meshingly connected at the bottom, and the second bevel gear 7 rotates with the screw rod 8 fixedly connected to the inside, and the screw rod 8 rotates with the adjustment block 9 connected to the outside thread to move, and the adjustment block 9 moves with the mounting brackets 12 fixedly connected to the outside on both sides to move, so that the height of the fixing bracket can be adjusted according to the height of the bed, which is convenient for medical staff to operate, and can also meet the needs of different patients when doing fluoroscopy. The posture improves the practicality of the dialysis catheter fixing bracket. When fixing the dialysis catheter, the pull ring 15 is pulled to move the pull rod 14, and the pull rod 14 moves with the first arc-shaped clamping plate 16 fixedly connected to the bottom. Then, when the pull rod 14 moves with the first arc-shaped clamping plate 16, the spring 17 sleeved on the outside of the pull rod 14 is squeezed, and then the dialysis catheter is placed on the upper part of the second arc-shaped clamping plate 18, and then the pull ring 15 is released. Under the reaction force of the spring 17, the dialysis catheter can be fixed by the first arc-shaped clamping plate 16, which makes it easy to fix the dialysis catheter, prevents the catheter from accidentally moving or falling off during use, and improves the stability of the dialysis catheter during use.
