Abstract

The utility model relates to an arteriovenous retention suture needle with a butterfly wing. A retention suture needle thimble seat of the retention suture needle is provided with a butterfly wing made of atoxic plastic, the butterfly wing has a card movable connection with the retention suture needle thimble seat, and each fin of the butterfly wing is provided with a plurality of symmetrical small holes. When the retention suture needle is for clinical use, thin lines can be used for passing through the small hole to bind the retention suture needle on the hand, and the retention suture needle is stably fixed to the hand without sliding transfer, and further relieving the nursing care number and the unnecessary pain of the patients. The utility model has the advantage of convenient and safe use.

Description

A kind of iv cannule that has the butterfly wing

This utility model relates to the injection medical apparatus and instruments, particularly a kind of iv cannule that has the butterfly wing.

The remaining needle that uses in medical treatment in the past because the Injector Bushing base is a garden shape, is difficult for fixing when clinical use, and causes displacement easily, thereby increase the difficulty of nursery work and increase unnecessary misery to patient.

The purpose of this utility model provides a kind of deficiency that can overcome above-mentioned remaining needle, can steadily fix, and is difficult for causing the iv cannule of displacement.

The purpose of this utility model is achieved in that with non-toxic plastic makes the symmetric butterfly wing, this butterfly wing and Injector Bushing base cassette flexibly connect, have several symmetric apertures on every limit fin of the butterfly wing, when remaining needle during in clinical use, available fine rule passes butterfly wing aperture, and remaining needle is bundled on hand, thereby remaining needle can be fixed on hand reposefully, and can not cause the remaining needle sliding transfer, thereby can alleviate nursing work load, reduce the unnecessary misery of patient.

Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated.

Fig. 1 is each component diagram of iv cannule that has the butterfly wing.

Fig. 2 is the iv cannule general assembly composite diagram that has the butterfly wing.

With reference to Fig. 1, Fig. 2, a kind of iv cannule that has the butterfly wing of this utility model has draw point pipe (1), draw point base (2), remaining needle sleeve pipe (3), Injector Bushing base (4), return channel (5), seat plug (6), draw point pipe (1) is formed the needle tubing assembly with draw point base (2), and remaining needle sleeve pipe (3) is formed the remaining needle assembly with Injector Bushing base (4).The butterfly wing (7) is housed on Injector Bushing base (4), this butterfly wing (7) is made with non-toxic plastic, the butterfly wing (7) flexibly connects for cassette with Injector Bushing base (4), have several symmetric apertures on every limit fin of the butterfly wing (7), remaining needle is tied up reposefully be fixed on hand thereby available line passes symmetrical aperture.Handgrip (8) is arranged on draw point base (2), in the time of can making clinical use puncture convenient, accurately.Done a symmetric overhang at the tail end of Injector Bushing base (4), can play threaded function, seat plug (6) is for having the stopper of spiral muzzle lid, can screw thread rotation combine jam-pack with the tail end overhang of Injector Bushing base (4) in use, can prevent effectively that seat plug (6) from coming off, thereby guarantee the use of remaining needle safety and sanitation.

This utility model is a kind of can make when having the clinical use of the iv cannule of the butterfly wing remaining needle steady, safe be fixed on patient on hand, and easy to operate, safe and reliable, have good social benefit and promotion prospect.
