In addition, since the dialysis tube 41 is movably caught in the U-shaped plate 20, the U-shaped plate 20 does not press the dialysis tube 41, resulting in blockage thereof, and the like.

The minimum distance between the pair of U-shaped plates 20 in this embodiment is equal to the length of the blood collection port 40 in the direction of the dialysis tube 41. In particular, this allows to better limit the movement of the blood collection port 40 between the pair of U-shaped plates 20, avoiding its detachment.

The arc surface of the hemisphere 23 in this embodiment is a smooth surface. Specifically, because a pair of U-shaped plates 20 and the openings opposite to the U-shaped plates are provided, the blood collection tube can be stably clamped in the U-shaped plates 20 without the strong blocking effect of the hemispheres 23 on the blood collection tube, and the dialysis tube 41 can be better clamped in/out by the smooth surfaces of the hemispheres 23.

In the embodiment, the fixing strips 11 are arranged on both sides of one surface of the fixing belt 10 close to the connecting plate 30; one side and two ends of the pair of fixing strips 11, which are far away from each other, are fixedly connected with the fixing belt 10; one surface of the connecting plate 30, which is far away from the U-shaped plate 20, is fixedly connected with a connecting block 31, and one surface of the connecting block 31, which is far away from the connecting plate 30, is fixedly provided with a fixing plate 32; both ends of the fixing plate 32 are disposed between the fixing strip 11 and the fixing band 10. Specifically, fixing the fixing plate 32 between the fixing strip 11 and the fixing band 10 can conveniently adjust the position of the fixing plate 32, and can fix a plurality of dialysis tubes 41 on the fixing band 10 at the same time.

The fixing plate 32 in this embodiment is an arc shape fitting the arm of the human body. In particular, patient discomfort may be avoided.

The fixing strip 11 in this embodiment is made of an elastic material. Specifically, when the fixed strip 11 is the elasticity material, and when the flat-out with fixed band 10 fully laminating, after fixed band 10 is crooked, just can stretch fixed strip 11, make it have certain elasticity, can laminate better on fixed band 10 to with fixed plate 32 chucking.

In this embodiment, a plurality of anti-slip rubber strips are disposed on one side of the fixing band 10 close to the fixing strip 11. Specifically, the anti-slip rubber strip can effectively prevent the fixing plate 32 from sliding between the fixing band 10 and the fixing strip 11.

The fixing band 10 in this embodiment has both ends provided with magic tapes. Specifically, the magic tape can significantly improve the fixing efficiency of the fixing band 10.
