Blood purification equipment dialyzer clamp

Abstract

The invention discloses a blood purification equipment dialyzer clamp. The blood purification equipment dialyzer clamp comprises an upper clamp body, a lower clamp body and a shell with an opening formed in one end, wherein a strip-shaped guide hole is formed in a lower installation portion of the lower clamp body, in addition, the portion, corresponding to the guide hole, of the bottom face of the lower clamp body is a downward-convex arc surface, a connecting rod is inserted into the other end of the shell, the inner end of the connecting rod is installed in the shell through a radial locating device, the outer end of the connecting rod penetrates through the guide hole of the lower clamp body and is connected with the upper clamp body, the connecting rod is further movably sleeved with a backing ring located at the side, away from the upper clamp body, of the lower clamp body, a tightly-butting device abutting the backing ring with the lower clamp body tightly is arranged at the side, away from the lower clamp body, of the backing ring, and when an upper handhold portion is close to a lower handhold portion mutually, the upper clamp body and the lower clamp body are opened simultaneously. By means of the structure, the opening range of the dialyzer clamp is remarkably increased, so that the application range of the dialyzer clamp is wider, the clamping force is more uniform, the clamping is more stable, the clamping effect is better, and the slipping is not prone to occurring.

Description

technical field [0001] The invention belongs to the technical field of blood purification equipment, and in particular relates to a dialyzer clip on the blood purification equipment. Background technique [0002] At present, the dialyzer, filter or perfusion device on the blood purification equipment is usually clamped and fixed by the dialyzer clamp. The traditional dialyzer clamp mainly includes an open fixing base, on which a sleeve is fixed, one end of the sleeve is connected with the fixing base, and the other end of the sleeve is fixed with a lower clip, which includes a block The lower installation part of the lower installation part is fixed with the sleeve, one end of the lower installation part extends upwards to form a first clamping part, and the other end of the lower installation part extends outwards and upwards to form a lower handle part and a support part respectively; A pull rod is inserted into the barrel, one end of the pull rod is installed in the slee...

AI Technical Summary

Problems solved by technology

[0004] (1) The unilateral opening and closing of the upper clamp is limited. If the diameter of the dialyzer, filter or perfusion device is too large, the clamping cannot be performed, and if the diameter is too small, the clamping will not be tight, which narrows the scope of application of the dialyzer clamp. ;

[0005] (2) The angle and position of the lower clamp are fixed, and the clamping force of the upper clamp and the lower clamp on the dialyzer, filter or perfusion device is uneven and easy to slip;

[0006] (3) The dialyzer clamp can only be opened by applying downward force to the upper handle to rotate the upper clamp, which is laborious to open and inconvenient to use;

[0007] (4), the lower clamp is fixed to the sleeve, the upper clamp and the lower clamp cannot rotate around the central axis of the sleeve, and the position or angle of the dialyzer, filter or perfusion device cannot be adjusted conveniently, which is inconvenient to use;

[0008] (5) When the support part of the upper clip and the lower clip is used as a support point to open and close, there is an angle between the tension of the upper clip on the pull rod and the central axis of the pull rod, so that the force of the tensioning device is uneven, and the tension of the tensioning device is not uniform. The loss is large, which is not conducive to the extension of the service life;

[0009] (6) The force received in the clamping of the lower clamp can only be borne by the structural strength of the lower clamp itself, which requires high strength for the lower clamp, and some manufacturers strengthen the structure of the lower clamp by setting reinforcing ribs outside the lower clamp, but The structure of this lower clip is complex
