Abstract
The utility model discloses a novel lever type remaining needle connecting head which comprises an infusion tube extension tube connecting head, locking columns, supporting rods, a connecting plug, a positive pressure connecting head and a clamping ring. The novel lever type remaining needle connecting head is characterized in that the symmetrical supporting rods are fixedly connected to the two sides of the infusion tube extension tube connecting head, the locking columns are fixedly connected at the top ends of the supporting rods, the connecting plug is fixedly connected into the infusion tube extension tube connecting head, the matched positive pressure connecting head is arranged on the outer surface of the connecting plug, the clamping ring is fixed on the outer surface of the positive pressure connecting head in a sleeved mode, the tail ends of the locking columns are in a bent-hook shape, and the locking columns and the supporting rods are made of medical plastics. The novel lever type remaining needle connecting head is reasonable in design, simple in structure and convenient to use, air is prevented from being injected in when the remaining needle connecting head and the infusion tube extension tube connecting head are tightly screwed, the connecting head is quickly fixed, and the working efficiency of medical workers is improved.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of new lever type remaining needle jointing.
Background technology
In long-term clinical practice, when by connection remaining needle joint and tube for transfusion joint of extending, need to tighten, in rundown process, the operating time is grown to medical personnel's work efficiency and reduces, and sometimes often can be by air Injection in indwelling needle.Therefore, the convenient, fast developing direction that has become modern medicine.
Utility model content
The purpose of this utility model is to provide a kind of new lever type remaining needle jointing, while preventing remaining needle joint and tube for transfusion joint of extending to tighten, by air Injection, joint is fixed improved medical personnel's work efficiency more efficiently.
To achieve these goals, the technical solution of employing is this utility model:
A kind of new lever type remaining needle jointing, comprise tube for transfusion joint of extending, locking post, pole, connecting pin, positive pressure connector, snap ring, it is characterized in that: described tube for transfusion joint of extending both sides are fixedly connected with symmetrical pole, described pole top is fixedly connected with locking post, described tube for transfusion joint of extending inside is fixedly connected with connecting pin, described connecting pin outer surface is provided with the positive pressure connector matching, described positive pressure connector outer surface is fixed with snap ring, described locking post tail end is hook solid, described locking post and described pole are medical plastic.
The beneficial effect that this utility model can produce: reasonable in design, simple in structure, easy to use, while preventing remaining needle joint and tube for transfusion joint of extending to tighten, by air Injection, joint is fixed improved medical personnel's work efficiency more efficiently.
Accompanying drawing explanation
