Abstract
The utility model relates to an injecting part device inside a disposable use dialysis pipeline, which belongs to medical instruments, and is adaptable to being used in assay of clinical medicine injection or blood draw of a dialysis pipeline. The three-way injecting part comprises a three-way seat, a three-way cover cap and a sealing part (thermal plasticity elastomer materials); the three-way cover cap is divided into a red color and a blue color in order to distinguish arterial ducts and venous ducts; the three-way seat is made of transparent materials, thereby being capable of conveniently observing a blood flow situation inside the pipeline from the outside of the pipeline; an inverted projecting rib structure is arranged inside the three-way cover cap; an outer projecting rib is arranged on the end surface of the three-way seat; simultaneously the sealing part and the end surface of an inner hole of the three-way seat can be designed into a projecting rib structure type; and assembly of the three-way injecting part can ensure fastness and tightness of the three-way injecting part.
Description
Technical field
This utility model relates to a kind of disposable use hemodialysis pipeline device, be one of effective measures such as treatment acute and chronic renal failure and medicine, toxic poisoning etc., also be to use the most general method in the kidney surrogate therapeutic clinically at present, belong to medical instruments field.
Technical background
Hemodialysis is one of effective measures such as treatment acute or chronic renal failure and medicine, toxic poisoning etc., also is to use the most general method in the kidney surrogate therapeutic clinically at present.Apparatuses such as hemodialysis pipeline, dialyser and dialysis machine are the essential conditions of carrying out hemodialysis clinically.And the dialysis pipeline uses with matched with devices such as dialyser, dialysis machines clinically, bears the function of blood access in hemodialysis.Wherein the arterial blood pipeline is born outside the blood samples of patients lead body, and venous line is then born treated blood is sent back in patient's body.Compositions such as present Dialysis tubing route irrigator joint, puncture needle locked joints group, flow folder, air kettle, screwed union, threeway injection member, dialyser joint, air filter, pump line.In the dialysis pipeline, be mainly used in clinical extraction blood and carry out medical observation and filling medicinal liquid, but threeway injection member commonly used at present easily causes medical personnel's mistake thorn in clinical use to accidentally injure phenomenon in the dosing process; Also can leak the blood phenomenon owing to poor sealing causes.
Summary of the invention
The purpose of this utility model is to provide a kind of good airproof performance, disposable use hemodialysis pipeline injection member device safe in utilization.
In order to address the above problem, this utility model is achieved in that the injection member device in the disposable use hemodialysis pipeline, comprise the plastic material threeway injection member of being with flap, the threeway injection member is by the threeway seat, threeway is blocked a shot and is made up of the sealing member that thermoplastic elastic material is made, set up an outer convex rib at threeway seat and threeway block cooperation place, threeway block inner edge has button convex tendon in, the threeway seat has inner convex rib and sealing member to carry out convex tendon with the end face of sealing member cooperation place to cooperate, when sealing member cooperates assembling with the threeway seat after, the convex tendon of button convex tendon and threeway seat buckles in the threeway block, and feasible seat inner seal liner is compacted to allow its sealing firmly.
Injection member device in the disposable use hemodialysis pipeline of this utility model is difficult for the accidental injury of mistake thorn owing to be provided with the flap device in the dosing process; Because the convex tendon of button convex tendon and threeway seat buckles in the block of injection member, feasible seat inner seal liner is compacted to allow its sealing firmly.Can not cause clinical leakage blood.
