[0032] The present utility model provides a dialysis catheter fixing device as Figures 1 - 5 shown, which includes a fixing patch 1. Three adhesive patches 2 are arranged at the lower end of the fixing patch 1. A fixing rotating seat 3 is arranged above the center of the upper end of the fixing patch 1. Fixing clamping blocks 4 are slidably connected to both the left and right sides of the upper end of the fixing rotating seat 3. The left side of the rear end of the fixing rotating seat 3 is connected to a fixing clip 6 through a connecting rope 5. When performing dialysis on a patient, the dialysis catheter can be clamped at the upper end of the fixing rotating seat 3 by the two fixing clamping blocks 4 and adhered to the skin through the fixing patch 1 at the lower end of the fixing rotating seat 3, preventing the dialysis catheter from moving out of the patient's body. The fixing patch 1 made of silicone can better fit the skin, be more comfortable, and the fixing patch 1 can be pasted multiple times by successively tearing off the three adhesive patches 2 of the same size arranged at the lower end from bottom to top, enabling the fixing device to be reused repeatedly, which can not only reduce the dialysis cost but also be more environmentally friendly. At the same time, the fixing rotating seat 3 can be clamped on the clothes by the fixing clip 6 connected to the left side of the rear end through the connecting rope 5 to further fix the dialysis tube and ensure the connection stability of the dialysis tube.

[0033] Preferably, the adhesive patch 2 on the lower side is connected to the lower end of the fixing patch 1 through a plurality of outer connecting columns 7. The plurality of outer connecting columns 7 penetrate through the uppermost adhesive patch 2 and the middle adhesive patch 2 vertically. The middle adhesive patch 2 is connected to the lower end of the fixing patch 1 through a plurality of inner connecting columns 8, and the plurality of inner connecting columns 8 penetrate through the uppermost adhesive patch 2 vertically. The fixing patch 1 is made of silica gel. During the repeated use of the fixing device, the lower end of the fixing device can be made sticky again by tearing off the adhesive patch 2 from bottom to top in sequence, and it can be stuck on the skin again. Since the plurality of outer connecting columns 7 and the plurality of inner connecting columns 8 connecting the lowermost adhesive patch 2 and the middle adhesive patch 2 are both made of easily tearable soft materials, when pulling down the adhesive patch 2, the plurality of outer connecting columns 7 or the plurality of inner connecting columns 8 connecting the adhesive patch 2 and the fixing patch 1 will break, so that the adhesive patch 2 can be smoothly torn off from the lower end of the fixing patch 1, and then the adhesive patch 2 or the fixing patch 1 at the upper end of the torn adhesive patch 2 is exposed. The fixing patch 1 or the adhesive patch 2 is pasted on the skin again through the adhesive at the lower end.

[0034] Preferably, the fixed turntable 3 is rotatably connected to the upper end of the fixing patch 1 through a rotating chuck 9 and a rotating disk 10. The rotating chuck 9 is fixedly connected to the upper end of the fixing patch 1. The rotating disk 10 is fixedly connected to the center of the lower end of the fixed turntable 3 and is rotatably connected inside the rotating chuck 9, so that the two fixed blocks 4 can rotate on the upper end of the fixing patch 1 through the fixed turntable 3, so that the dialysis catheter can rotate on the upper end of the fixing patch 1, making it more convenient to adjust the position of the dialysis catheter and more convenient to connect the dialysis catheter.

[0035] Preferably, fixing grooves 11 are respectively formed inside the opposite ends of the two fixed blocks 4. Clamping slide bars 12 are fixedly connected to the front and rear sides of the lower ends of the two fixed blocks 4. The two clamping slide bars 12 at the lower end of the fixed block 4 on the left are located inside the two clamping slide bars 12 at the lower end of the fixed block 4 on the right. The four clamping slide bars 12 are all slidably connected to the inside of the upper end of the fixed turntable 3 through clamping chutes 13, and the four clamping chutes 13 are all formed inside the upper end of the fixed turntable 3. Pressing plates 14 are fixedly connected to the ends of the two clamping slide bars 12 at the lower end of the same fixed block 4 close to the other fixed block 4, so that the two fixed blocks 4 can be separated from each other by pressing the pressing plates 14 on both sides, making it more convenient for the dialysis catheter to be inserted and removed. And the two fixed blocks 4 can clamp the dialysis catheter through the fixing grooves 11 formed inside the opposite ends, ensuring the stable fixation of the dialysis catheter and preventing it from falling off.

[0036] Preferably, the pressing plate 14 is attached to one end of the fixed rotating base 3 away from the fixed clamping block 4. A central portion of the pressing plate 14 near one end of the fixed clamping block 4 is fixedly connected to an elastic telescopic rod 15. The elastic telescopic rod 15 is slidably connected to the inside of the fixed rotating base 3 through a telescopic chute 16. The telescopic chute 16 is opened inside the fixed rotating base 3 near one end of the pressing plate 14. A clamping spring 17 is arranged inside one end of the elastic telescopic rod 15 away from the pressing plate 14 and is elastically connected to the inside of the telescopic chute 16 through the clamping spring 17, so that the pressing plate 14 can be elastically connected to both sides of the fixed rotating base 3 through the elastic telescopic rod 15 and the clamping spring 17, thereby enabling the fixed clamping block 4 to be elastically connected to the upper end of the fixed rotating base 3. Therefore, when the pressing plate 14 is released, the two fixed clamping blocks 4 can move closer to the middle under the action of the elastic connection and clamp the dialysis catheter.

[0037] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
