CN2306012Y - Arteriovenous retention suture needle with medicine feeding mouth - Google Patents

Abstract

The utility model relates to an arteriovenous retention suture needle with a medicine feeding mouth. The retention suture needle thimble seat of the retention suture needle is provided with a cylindric medicine feeding mouth, and the cylindric medicine feeding mouth is provided with a medicine feeding interface. A columnar circular hole is arranged in the medicine feeding interface, and the outer part of the columnar circular hole is coated with a strip of medical leather hose which can automatically open and close. When the patient is in emergent need of injecting other medication during the injection, the cover of the medicine feeding interface is opened, and other medication can be injected into the medicine feeding mouth. Therefore, the pain of the patient is not increased, and the needed medicine is injected to the patient rapidly and in time. The utility model has the advantage of high safety and convenience.

Description

A kind of iv cannule that has dosing mouth

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

The remaining needle that in medical treatment at present, uses, because the Injector Bushing base is that sealing is connected with tube for transfusion, when clinical use, when need during to the patient injection other medicines, must inject infusion bottle earlier, from tube for transfusion, inject patient's blood vessel more at leisure, or inject a pin more in addition, when patient is badly in need of certain medicine, tends to delay treatment or increase patient's misery.

The purpose of this utility model provides a kind of deficiency that can overcome above-mentioned remaining needle, neither needs to inject in addition to patient, can fast required medicine be injected into the iv cannule of patient's blood vessel again.

The purpose of this utility model is achieved in that opens a dosing mouth on the Injector Bushing base, the dosing interface is housed on the dosing mouth, when patient need inject other medicines, open the dosing access flap, can directly inject other medicines inward, thereby neither need again to patient injection, give patient with the injection in time of required medicine apace again.

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 dosing mouth.

Fig. 2 is the iv cannule general assembly composite diagram that has dosing mouth.

With reference to Fig. 1, Fig. 2, a kind of iv cannule that has dosing mouth 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).On Injector Bushing base (4), have a garden cylindricality dosing mouth (7), on this garden cylindricality dosing mouth (7), dosing interface (8) is arranged, there is a cylindricality hole (9) this dosing interface (8) the inside, cylindricality hole (9) is outer to be surrounded by a medical leather hose (10), and this medical leather hose (10) can play the automatic shutter effect, when dosing interface (8) when not using, medical leather hose (10) plays sealing process, when dosing interface (8) used, medical leather hose (10) was open-minded, inwards injectable drug.Injector Bushing base (4) go up and dosing mouth (7) over against another side done folding symmetrical double-vane (11), can have several symmetrical apertures on every limit fin of this double-vane, pass aperture with line and remaining needle can be tied up reposefully and be fixed on hand, thereby avoid the remaining needle sliding transfer.Handgrip (8) is arranged, handled easily in the time of can making clinical use on draw point base (2).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.

A kind of iv cannule that has dosing mouth of this utility model can not increase patient's misery in time to the required medicine of patient injection in use, and is safe and reliable, convenient feasible, is with a wide range of applications.
