Description
Technical field
This utility model relates to a kind of disposable hemodialysis pipeline, especially a kind of haemodialysis equipment of being communicated with human vein of being used for.Belong to medical mechanical domain.
Background technology
" hemodialysis " is the effective means that earns a bare living in the uremic patient anaphase, and it is a mode of using extracorporeal circulation, allows blood flow through piped artificial kidney, in the patient of carrying out refluxing again behind the blood purification.Carrying out hemodialysis needs to set up on the sufferer limbs earlier and can allow the convenient effusive vascular access of blood, and the most frequently used method is to build an arteriovenous fistula with surgical operation, just can be used for hemodialysis after postoperative 4 to 6 all fistula maturations.During dialysis, insert two syringe needles at the fistula place, blood enters artificial kidney by wherein a syringe needle outflow is external, and the blood after the purification goes out artificial kidney and flowed back in the body by another syringe needle.
Existing disposable blood dialysis pipeline mainly by: pipeline, injection part, clip, dialyser joint, puncture needle joint, drip tube etc. and form.Wherein injection part is one section elastomeric material, and its two ends are set in respectively on two sections pipelines, and during use, the injection part of making by this section elastomeric material that punctures adds materials such as medicament in the dialysis pipeline.The defective that said structure exists is: because injection part is one section rubber tube without any protection, therefore, the mistake puncture phenomenon in the time of can't avoiding using causes the unsafe condition of instrument damage and therapeutic process.In addition, mainly adopt at the position of injection part by said apparatus preliminary filling normal saline to charge into normal saline, still, the shortcoming that this operational approach has is:
1,, therefore often causes the situation of mistake puncture easily because existing injection part is used the structure of rubber tube usually.
2, by the pre-mode of injection part puncture, operate very loaded down with trivial details towards normal saline.
The utility model content
The purpose of this utility model: aim to provide a kind of disposable hemodialysis pipeline, mainly solve existing apparatus preliminary filling normal saline and mainly adopt at the position of injection part the technical problem that charges into the normal saline complex operation, causes mistake to puncture easily, this utility model product carries out the preliminary filling of normal saline in conjunction with the puncture needle joint, operation is handy and safe very, and injection part is not easy to be stung by mistake.
For addressing the above problem, this utility model is achieved in that
This disposable hemodialysis pipeline, comprise that conduit 4, band helmet two connect pipe 11, blood filter body 5, two connects pipe 3, it is characterized in that: described band helmet two connect pipe 11 by many sections conduits 4 in regular turn with blood filter body 5 and be in two of the pipeline other end and connect pipe and 3 be connected conducting; Wherein blood filter body 5 one ends are provided with blood filter threeway lid 13, be provided with stent filter screen 14 in the cavity of the other end, on this blood filter threeway lid 13, set up three separately simultaneously and connecting jack, except that one of them jack connects pipe 11 is connected through a latex plug molectron and band helmet two, setting up the brasnch conduct 4 of a band air filter 12 and band spiral two in its two other jacks separately and connecting and manage 7 brasnch conduct 4; Described two outer ends that connect pipe 3 are being provided with the double end of locking articulation 2 and being connected with the locking articulation and are taking over 1.
Described latex plug molectron is by latex obturating plug 9, latex gag 10 and be positioned at the intermediary latex plug 16 of latex gag and constitute jointly.
The end of the brasnch conduct 4 of described band air filter 12 has helmet 6, and the end that described band spiral two connects the brasnch conduct 4 of pipe 7 has helmet.
Described conduit 4 is provided with elasticity folder 15.
By technique scheme, the beneficial effects of the utility model are:
1, this utility model normal saline circulating connection mat socket part one end be provided with one with the corresponding valve of opening of puncture needle joint, can carry out the preliminary filling of normal saline, the normal saline of preliminary filling is at arteriovenous pipeline internal recycle, makes preliminary filling operation handy and safe more.
2, this utility model injection part has the screening glass structure of wing, and main body is plastic material, and it can avoid the mistake phenomenon that punctures, and the equipment that causes thus damages phenomenon, has ensured hemodialysis process safe reliability.
Description of drawings
Accompanying drawing is for being structural representation of the present utility model.
Among the figure: the 1-double end is taken over two joint-spirals two of 2-locking articulation 3-and is connected pipe 4-conduit 5-blood filter body 6-spiral two and connect 7-spiral two and connect pipe 8-elasticity folder 9-10-latex plug 11-band helmet two pass joint 12-air filter 13-blood filter threeways lid 14-stent filter screen 15-elasticity folder 16-latex plug
The specific embodiment
Disposable hemodialysis pipeline as shown in the figure, comprise that conduit 4, band helmet two connect pipe 11, blood filter body 5, two connects pipe 3, it is characterized in that: described band helmet two connect pipe 11 by many sections conduits 4 in regular turn with blood filter body 5 and be in two of the pipeline other end and connect pipe and 3 be connected conducting; Wherein blood filter body 5 one ends are provided with blood filter threeway lid 13, be provided with stent filter screen 14 in the cavity of the other end, on this blood filter threeway lid 13, set up three separately simultaneously and connecting jack, except that one of them jack connects pipe 11 is connected through a latex plug molectron and band helmet two, setting up the brasnch conduct 4 of a band air filter 12 and band spiral two in its two other jacks separately and connecting and manage 7 brasnch conduct 4; Described two outer ends that connect pipe 3 are being provided with the double end of locking articulation 2 and being connected with the locking articulation and are taking over 1.
