Description
Technical field
This utility model relates to vessel clamp, refers in particular to a kind of vessel clamp for hemodialysis conduit, belongs to technical field of medical equipment.
Background technology
In present medical domain, hemodialysis catheter is a kind of medical apparatus and instruments for blood purification treatment, is mainly used in clinical blood dialyzing access conduit internal jugular vein puncture operation.In Clinical practice process, one end of hemodialysis catheter connects human body, and the other end is connected to extracorporeal blood purifier, with by the blood syringe after being purified by purifier in human vein.When needs are treated, only need open the vessel clamp be enclosed within above hemodialysis conduit extension pipe, namely blood go into circulation.After completed treatment, folder closes vessel clamp, the blood circulation in occlude blood Dialysis tubing, and removes extracorporeal blood purifier, make patient can activity freely.So the vitals of blood circulation when vessel clamp is for controlling blood purification, whether the use safety of vessel clamp directly has influence on the life security of patient.But as shown in Figure 1, poling hole 11 edge designs that existing vessel clamp 1 is offered is acute angle, when conduit particularly closes conduit flow at vessel clamp 1 folder through pore 11, now there is expanding-contracting action in conduit, is easy to scratch or weighs silica gel catheter wounded, and then cause catheter rupture and oozing of blood.In addition, the buckling end of vessel clamp 1 afterbody adopts the slip fixed structure on inclined-plane, when need press from both sides close conduit time, described in the upper end edge of pressing vessel clamp, inclined-plane slides and presses down, and fastens in the draw-in groove of its afterbody, this process center line and inclined-plane sliding friction, resistance is comparatively large, and user operation effort, is not easy one-handed performance, thus impact folder closes the speed of conduit, brings great inconvenience to Clinical practice.
Utility model content
The purpose of this utility model is that solving the existing vessel clamp for hemodialysis conduit exists easy scratch conduit and operation effort, inconvenient problem with use is brought to Clinical practice, a kind of hemodialysis vessel clamp is provided, this equal upper end, vessel clamp opening both sides and tail end adopt arcwall face, slided on tail end arcwall face by upper end arcwall face, greatly reduce fastening power required when folder closes conduit, realize the object of one-handed performance, there is one-hand operation, use laborsaving and feature easily.
The purpose of this utility model can reach by the following technical solutions:
A kind of hemodialysis vessel clamp, comprise vessel clamp body, described vessel clamp is the semi-loop structure of elastic deformation, is provided with an opening closed by elastic deformation clamping; Described vessel clamp body both sides cambered surface is respectively equipped with the through hole laterally run through, and inside is provided with upper and lower corresponding projection, it is characterized in that: the straight flange top in described open upper side face is arc buckle, the top of the straight flange of downside is provided with the arcwall face to the bending of arc buckle, and the bottom of described arcwall face is provided with and bends inwards and the draw-in groove mutually fastened with arc buckle.
As with improvement, the edge of described through hole is obtuse angle structure.
As with improvement, described draw-in groove is right angle draw-in groove, and the lateral surface that arc buckle picks up the straight flange closing its upper surface and open upper side face after in draw-in groove is coplanar.
Further, the U-shaped structure of described vessel clamp body, the lateral surface being positioned at open upper side face straight flange is provided with for anti-skidding sawtooth.
Further, described vessel clamp body is plastics, timber or metal integrative-structure.
Implement this utility model, there is following beneficial effect:
1, opening both sides of the present utility model end face adopts arcuate structure, arc is buckled in and fastens in the process of draw-in groove, arc buckle arcuately face slides, reduce the frictional force in sliding process, arc buckle is made to fasten in draw-in groove rapidly, it is laborsaving, convenient to use, and can realize unmarried operation, the workload reducing medical personnel and the object of increasing work efficiency.
2, employing obtuse angle, through hole edge of the present utility model structure; when conduit is through through hole and when being closed circulation by folder, the scratch of through hole edge can be prevented or scratch conduit, the service life of elongate catheter; the danger brought when reducing hemodialysis, can protect the personal safety of patient and medical care better.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Specific embodiment 1:
With reference to Fig. 3 and Fig. 4, the present embodiment comprises vessel clamp body, and described vessel clamp body 1 is the semi-loop structure of elastic deformation, is provided with an opening 11 closed by elastic deformation clamping; Described vessel clamp body 1 both sides cambered surface is respectively equipped with the through hole laterally run through, and inside is provided with upper and lower corresponding projection 12, it is characterized in that: the straight flange top of described opening 11 upper side is arc buckle 13, the top of the straight flange of its downside is provided with the arcwall face 14 to the bending of arc buckle, and the bottom of described arcwall face 14 is provided with and bends inwards and the draw-in groove 15 mutually fastened with arc buckle.In the process of normal work, conduit 2 runs through whole vessel clamp 1 through through hole, when needing the blood circulation in closure catheter for closing 2, available finger compresses the straight flange lateral surface of opening 11 upper side, then arc buckle 13 contact with arcwall face 14 and arcuately face 14 slide, by being slidably connected between arc surface, arc buckle 13 can be fastened in draw-in groove 15 rapidly, reduce the frictional force in sliding process, unmarried operation, the workload reducing medical personnel and the object of increasing work efficiency can be realized.
As shown in Figure 3, in order to prevent the scratch of through hole edge or scratch conduit, the danger brought when reducing hemodialysis, the edge of described through hole is obtuse angle structure, and it is connected by plane-plane contact with through the conduit on it.
As shown in Figure 4, be fastened on after in draw-in groove 15 at arc buckle 13, in order to ensure that draw-in groove 15 bears pressure with optimized structure, thus realize maximum bearing capacity, described draw-in groove 15 is right angle draw-in groove, and the lateral surface that arc buckle 13 is fastened on the straight flange of its upper surface and opening 11 upper side after in draw-in groove 15 is coplanar.In order to prevent arc buckle 13 from deviating from draw-in groove 15 further, the U-shaped structure of described vessel clamp body 1, the lateral surface being positioned at opening 11 upper side straight flange is provided with for anti-skidding sawtooth 16.
Described vessel clamp body 1 is plastics, timber or metal integrative-structure.Metal can select the good materials of plasticity such as phosphor bronze, manganese steel and rustless steel.Because this vessel clamp 1 utilizes the plastic deformation character of material to carry out the object that folding capable of circulation controls catheter flow, the materials'use effect that plasticity is better is better, and therefore, except above material, other material with better plasticity is also applicable to this vessel clamp.
Above disclosedly be only a kind of preferred embodiment of this utility model, certainly can not limit the interest field of this utility model with this, therefore according to the equivalent variations that this utility model claim is done, still belong to the scope that this utility model is contained.
