Description

Fixing clamp for blood perfusion device and hemodialysis combined device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a fixing clamp of a blood perfusion device and a hemodialysis combiner.

Background

End-stage renal disease is what we often speak of chronic renal failure, and once a patient enters the uremic stage, the life of the patient needs to be continued by blood purification. The hemodialysis methods we often say include three methods of hemodialysis, hemofiltration and hemoperfusion. Blood perfusion is a blood purification method, which is a blood purification technology that introduces the blood of a patient into an extracorporeal circulation system from the body, introduces the blood into an perfusion device filled with a solid adsorbent, and removes exogenous or endogenous toxins, medicines or metabolic wastes which cannot be removed by dialysis in the blood through adsorption.

The hemoperfusion and hemodialysis combined treatment is characterized in that a hemoperfusion device is connected in series with a hemodialyzer in front of the hemodialyzer, the advantages of two different blood purification modes are utilized for complementation so as to comprehensively remove various toxins in a patient with uremia, the internal environment of a machine body is fully purified, and the hemoperfusion and hemodialysis combined treatment has obvious curative effects on treatment and delay of complications of a patient with maintenance hemodialysis. Meanwhile, the combination of blood perfusion and hemodialysis can also effectively improve the skin itch of uremia patients, so that the combination of blood perfusion and hemodialysis treatment can better improve the life quality of the patients.

Because hemoperfusion and hemodialysis need to be realized with the perfusion ware and the cerini dialyser cerini series connection, so except the problem of the pipe connection between the two, still relate to the fixed problem of both. At present, no quick, convenient and uniform fixing mode exists. The common method is to fix the adhesive tape or the iron fixing clamp, and the adhesive tape is wound and fixed for a relatively long time and is inconvenient. The iron fixation clamp is not telescopic, and the perfusion device and the dialyzer are often fixed by large force. Therefore, I have designed the utility model to accomplish this task better, conveniently and quickly.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome above technical problem, provide a blood perfusion ware and hemodialysis combiner fixation clamp that the structure is simple relatively, easily operation, can effectively save time.

In order to solve the technical problem, the utility model provides a technical scheme is hemoperfusion ware and hemodialysis union ware fixation clamp, its characterized in that: including first clamp and second clamp, first clamp middle part is equipped with the spread groove, second clamp middle part is equipped with the connecting seat with spread groove matched with, the connecting seat is pegged graft in the spread groove, the spread groove is equipped with torque spring with the connecting seat junction, first clamp and second clamp both ends symmetry respectively are equipped with first splint and second splint, first splint and second splint tip are the arc that is inside bent and open, and the middle part is the arc that outwards bends.

Preferably, the width of the connection part of the end part and the middle part of the first clamping plate and the second clamping plate is larger than that of the outer end of the end part.

Preferably, the arc of the first splint is greater than that of the second splint.

Preferably, the middle part of the connecting seat is of a concave structure.

Compared with the prior art, the utility model have following advantage: the novel blood purification dialyzer has the advantages of being simple to manufacture, good in performance, long in service life, convenient to use in daily blood purification treatment, good in universality and stability, convenient to fix the dialyzer, time-saving compared with the conventional rubberized fabric fixation, convenient to operate compared with the conventional non-torsion spring fixing clamp, and wide in applicability.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Combine the attached drawing, hemoperfusion ware and hemodialysis unite ware fixation clamp, its characterized in that: including first clamp 1 and second clamp 2, 1 middle part of first clamp is equipped with spread groove 3, 2 middle parts of second clamp are equipped with the connecting seat 4 with spread groove 3 matched with, connecting seat 4 pegs graft in spread groove 3, spread groove 3 is equipped with torque spring 5 with connecting seat 4 junction, first clamp 1 and 2 both ends of second clamp are the symmetry respectively and are equipped with first splint 6 and second splint 7, first splint 6 and 7 tip of second splint are the arc that is inside flexure, and the middle part is the arc that outwards flexes.

The width of the joint of the end part and the middle part of the first clamping plate 6 and the second clamping plate 7 is larger than that of the outer end of the end part.

The radian of the first clamping plate 6 is larger than that of the second clamping plate 7.

The middle part of the connecting seat 4 is of a concave structure.

The utility model discloses a torque spring that first clamp and second clamp use the middle part to link to each other is as the center, and both sides are equipped with the first splint and the second splint of radian variation in size respectively, in the use of jointly fixing hemoperfusion ware and hemodialyzer, at first, with the second splint of hand compression fixation clamp, make first splint part, put into the back with hemoperfusion ware and loosen the second splint with fixed, then, press down the hemodialyzer hard and get into in the second splint, make it fixed.

The utility model provides a clamp for jointly fixing a hemoperfusion apparatus and a hemodialyzer, and the two ends of a clamping plate are in arc shapes. Compare and to have more extensive suitability in current fixed intermediate layer, make things convenient for the fixed of cerini dialyser cerini. And the middle spring ensures that the perfusion device and the dialyzer are more convenient and stable to fix.
