Description

A kind of remaining needle

Technical field

The utility model is related to a kind of remaining needle, especially a kind of remaining needle with preferable pervasive performance.

Background technology

At present, even if the patient in ward has had remaining needle, will have an injection again to operating room, because ward is all to use The remaining needle of Y types, transfusion speed is slower, is not suitable for blood transfusion rescue.So entering to be used instead again after operating room the remaining needle of straight type. But it is to revert to behind ward and dislike straight type remaining needle inconvenience tube sealing to retain, so postoperative patient's same day is just straight type remaining needle Pull out, make remaining needle not play a part of it.

Utility model content

Utility model purpose：A kind of remaining needle that can be simultaneously applied to operating room and ward is provided.

Technical scheme：Remaining needle described in the utility model, including Y type positive pressure connectors, extension tube, one-hand clip, remaining needle Needle handle is held in seat, draw point and activity；Positive valve and end cap are respectively equipped with the two-way import of Y type positive pressure connectors；Extension tube One end is connected in the outlet of Y type positive pressure connectors, and the other end is connected on indwelling needle；It is provided with the excircle of indwelling needle One circle groove, activity is held needle handle and is set on groove by ring set；It is additionally provided with a fixation on the excircle of indwelling needle to hold Needle handle；One-hand clip is arranged in extension tube；Calparine cap is provided with the rear end of indwelling needle, is provided with and is prolonged in the front end of indwelling needle The draw point that long tube is connected.

Using in the rear end of indwelling needle, calparine cap is set, while extension tube is connected with side, such that it is able to according to need Select to be that the transfusion of Y types or straight type are infused, the transfusion requirement of ward and operating room is met, with preferable simple performance；Using Needle handle is held in fixation and activity is held needle handle collective effect and can effectively strengthen the stability of wearing of remaining needle, and activity is held needle handle and suffered from Person can be docile on skin by rotating when wearing fixed, with preferable wearing effect.

As further limits scheme of the present utility model, one-hand clip include U-shaped elastic clip, two finger pressure pieces, long hook with And short hook；The vertical section of outward bending is provided with one side top of U-shaped elastic clip；Two finger pressure pieces are separately fixed at U-shaped elasticity On the another side top of folder and vertical section；Long hook and short hook are located on same one side of U-shaped elastic clip, and are directed to U-shaped elasticity The another side of folder；Extension elongation of the extension elongation of long hook more than short hook.Another side can be hooked in transfusion using long hook and Hang in extension tube, another side is hooked by short hook when transfusion stops extension tube being clamped, it is convenient to use；Using Two finger pressure pieces facilitate finger to pinch pressure, using more convenient.

Compared with prior art, its advantage is the utility model：(1) heparin is set using in the rear end of indwelling needle Cap, while be connected with extension tube in side, such that it is able to select as needed to be the transfusion of Y types or straight type transfusion, meet ward and The transfusion of operating room is required, with preferable simple performance；(2) needle handle is held using fixation and activity hold needle handle collective effect can Effectively strengthen the stability of wearing of remaining needle, and activity is held needle handle and can pass through to rotate docile in skin when patient wears fixed On, with preferable wearing effect.
