Abstract
The utility model relates to an arteriovenous retaining needle with a three-way joint, which belongs to the technical field of medical apparatus. The rapid fluid infusion of large quantity as well as the discontinuous intravenous drug bolus are needed in clinical nursing activities, especially in the anesthesia, operation and the rescue of critical patients. The arteriovenous retaining needle has only one infusion catheter, and the needle stand thereof is clung and fixed to the skin at a puncturing point, while the direct intravenous drug bolus is easy to cause contamination and bleeding, and the operating efficiency is very low for the repeated inserting and pulling of the needle tube. The utility model has the technical proposal that the arteriovenous retaining needle 1 is provided with a fixed sheet 2, a side tube 3 and the arteriovenous retaining needle are communicated, and a three-way tube 4 and the side tube 3 are communicated and fixedly connected. The utility model has the advantages that the physical design is rational and practical; not only the advantage of high fluid infusion speed of the retaining needle is selected, but also the convenience of a three-way tube for adding drug is reserved; the utility model not only can be used for the blood transfusion and fluid infusion, but also can add drug at any time, so that the utility model has convenient use, greatly increases the operating efficiency of medical staff, and avoids the contamination and bleeding in the course of treatment.
Description
Technical field: this utility model relates to technical field of medical instruments, is a kind of iv cannule with threeway more specifically.
Background technology: in clinical nursing activity, especially in anesthesia, operation, critical patient rescue, sometimes a large amount of fast transfusions had both been needed, needing discontinuously again, vein pushes away medicine, iv cannule is owing to have only a tube for transfusion, its needle stand is close to point of puncture skin and fixing, and directly vein pushes away medicine and pollutes easily with hemorrhage, and needle tubing repeatedly plugs that to pull up operating efficiency very low.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of iv cannule with threeway of design.Its technical scheme is: iv cannule 1 is provided with stator 2, and side pipe 3 communicates with iv cannule 1, and tee T 4 communicates fixedly connected with side pipe 3.The advantage of this utility model is: the reasonable in design practicality, both selected the fast advantage of remaining needle transfusion speed, it is convenient to have kept the tee T dosing again, but both blood transfusion and infusion, at any time dosing again, easy to use, improved operation of medical workers efficient greatly, avoided therapeutic process pollution and hemorrhage.
Description of drawings: this accompanying drawing is this utility model structural representation.In the accompanying drawing: 1, iv cannule, 2, stator, 3, side pipe, 4, tee T.
The specific embodiment: iv cannule 1 is provided with stator 2, and side pipe 3 communicates with iv cannule 1, and tee T 4 communicates fixedly connected with side pipe 3.
Claims (1)
1, a kind of iv cannule with threeway is characterized in that: iv cannule (1) is provided with stator (2), and side pipe (3) communicates with iv cannule (1), and tee T (4) communicates fixedly connected with side pipe (3).
