Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a blood dialysis pipeline fixing clip. Background Art

[0002] Hemodialysis is one of the main renal replacement therapies for patients with renal failure. When performing hemodialysis, doctors first establish a vascular access for the patient, and then connect the pre-rinsed dialyzer and the disposable blood circuit tube to the patient's vascular access to establish extracorporeal circulation and start hemodialysis treatment. When performing hemodialysis, arterial and venous puncture needles need to be inserted into the patient's blood vessels. The pipelines connected to the rear of the arterial and venous puncture needles are numerous, complex, and heavy. The subsequent pipelines will pull the puncture needles. In order to prevent the puncture needles from being pulled or displaced, the pipelines need to be firmly fixed.

[0003] Currently, the common methods for fixing hemodialysis pipelines clinically are to use forceps to fix them on the bed sheet, or to fix the pipelines to the bedside railing, bed sheet, or the patient's wrist or arm through adhesive stickers. The above methods are not very stable. Therefore, there is a utility model patent with the patent number CN219558251U, which discloses a hemodialysis pipeline fixing device, including a fixed collar and a pipeline fixing clip connected to each other. Multiple fixing holes for fixing the hemodialysis pipeline are provided on the pipeline fixing clip. A clamping groove for the hemodialysis pipeline to be clamped into is provided on the fixing hole. A socket hole with adjustable aperture size is provided inside the fixed collar.

[0004] There are at least the following problems in the above patent: First, the diameter of the pipeline fixing clip is fixed and cannot adapt to pipelines of various diameters; second, the hemodialysis pipeline needs to enter the fixing hole from the clamping groove, which is not only inconvenient, but also may cause extrusion to the hemodialysis pipeline during the process of placing the pipeline, which may have an adverse effect. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model develops a blood dialysis pipeline fixing clip.

[0006] The technical solution for the utility model to solve the technical problem is: a blood dialysis pipeline fixing clip, including a mounting plate, straps are provided at both ends of the mounting plate, a base is detachably provided on the mounting plate, a fixing clip seat is provided at the center of the top of the base, movable clip bodies are slidably provided at both ends of the top of the base, and an elastic member is provided between the movable clip bodies and the fixing clip seat.

[0007] As an optimization, limit sliding grooves are provided at both ends of the top of the base, and limit sliding blocks matching the limit sliding grooves are provided at the bottom of the movable clamping body. The side wall of the limit sliding block is connected to the end of the limit sliding groove through an elastic member. By providing the limit sliding grooves and the limit sliding blocks, the stability of the movable clamping body sliding on the base can be ensured, and the movable clamping body can be prevented from detaching from the base.

[0008] As an optimization, the two groups of straps are detachably connected through a connecting member, and the connecting member is any one of a pin buckle, a magic tape and a magnetic buckle. By providing the connecting member, the straps can be conveniently tightened, and appropriate lengths can be loosened according to the position to be fixed, which can adapt to different application scenarios and has good universality in the clinical use process.

[0009] As an optimization, a counterbore is provided at the bottom of the mounting plate, a T-shaped boss is rotatably provided in the counterbore, the top of the T-shaped boss is connected to the bottom of the base, and a rubber layer matching the counterbore is provided on the outside of the T-shaped boss. By providing the counterbore and the T-shaped boss, the base can be rotated on the mounting plate; by providing the rubber layer, the base can be rotated manually and prevent the base from rotating arbitrarily.

[0010] As an optimization, arc-shaped pipe grooves are provided on both the fixed clamping seat and the movable clamping body. By providing the arc-shaped pipe grooves, the hemodialysis pipeline can be stably clamped.

[0011] As an optimization, a lining gasket is provided in the arc-shaped pipe groove, and the lining gasket is any one of silica gel, rubber and sponge. By providing the lining gasket, the hemodialysis pipeline can be protected and damage can be avoided.
