Dialysis tube fixing device for nephrology department

Abstract

The invention discloses a dialysis tube fixing device for the nephrology department. The dialysis tube fixing device comprises a positioning part and a fixing part, the positioning part comprises a positioning block, binding bands, supporting rods, rotating ball fixing seats, a limiting screw and a rotating ball, a through hole is formed in the middle of the positioning block, and the binding bands are arranged on the two sides of the positioning block correspondingly. When a dialysis tube penetrates through a first arc-shaped channel of a first clamping block and a second arc-shaped channel of a second clamping block, the dialysis tube is bent in a certain arc shape, when bent to a certain extent, the dialysis tube is not blocked, thus using of the dialysis tube is not affected, but whenthe dialysis tube is bent in the certain arc shape, the contact area between the dialysis tube and the first clamping block as well as the contact area between the dialysis tube and the second clamping block can be increased, friction force is increased, thus the dialysis tube is fixed more firmly by the first clamping block and the second clamping block, and meanwhile, if large force is generatedcarelessly to involve the blood dialysis tube, a second locking block moves towards one side of a first locking block to clamp and lock the dialysis tube.

Description

technical field [0001] The invention relates to the technical field of fixing devices, in particular to a dialysis tube fixing device for nephrology. Background technique [0002] At present, hemodialysis is the most effective treatment method for kidney disease. The dialysis device includes a dialyzer, a dialysis tube and a dialysis fluid supply system. For the new hemodialysis solution, many patients choose to puncture the abdomen, which requires the hemodialysis tube to be fixed in the abdomen of the human body, so the fixation of the hemodialysis tube is particularly important. [0003] In the prior art, when the dialysis tube is fixed, because the material of the dialysis tube is relatively soft, the clamping force cannot be too large when it is fixed, but this will lead to a poor fixing effect. Large force involves the hemodialysis tube, which will cause loosening between the fixing device and the hemodialysis tube, which will bring trouble to the treatment and also b...

[0003] In the prior art, when the dialysis tube is fixed, because the material of the dialysis tube is relatively soft, the clamping force cannot be too large when it is fixed, but this will lead to a poor fixing effect. A large force involving the hemodialysis tube will cause loosening between the fixing device and the hemodialysis tube, which will bring trouble to the treatment and bring pain to the patient
