Abstract

This utility model have employed a kind of arc needle handle formula injection needle, including: arc needle handle, described arc needle handle is fixed on pintle；Rubber needle sheaths, described rubber needle sheaths is looped around outside arc needle handle；Pintle, the cavity in described pintle turns on arc needle handle；Serum cap, described serum cap is fixed on pintle.This utility model syringe needle header structure is simple, reasonable, improves on original injection needle, makes easily, low cost, easy to use, efficiently avoid drawing liquid injection repeatedly and cause the wastes and pollution of medicinal liquid, being difficult to make syringe needle rust, be not likely to produce transfusion bag leakage, potential safety hazard is little.

Description

A kind of arc needle handle formula injection needle

Technical field

The utility model discloses a kind of arc needle handle formula injection needle, relate to the entry needle of arc needle handle Head, belongs to field of medical appliances.

Background technology

Syringe is a kind of common medical instruments, generally use 2 milliliters, 5 milliliters, 10 milliliters or 20 milliliters of syringes, even with 50 milliliters or 100 milliliters, intradermal injection is then with 1 milliliter of syringe.Note Emitter syringe can be plastics can also be that glass is made, and generally above have expression syringe The graduation indication of middle liquid volume.Glass syringe can carry out disinfection with autoclave, but because of Processing cost for plastic injector is relatively low, so modern medical service syringe majority is made of plastic, This also further reduces the risk of blood born diseases.Disease in the junkie of intravenous injection drug use Propagation especially HIV and the propagation of hepatitis and syringe needle and syringe reuse relevant.

Such as Fig. 2, the outside of needle handle 11 is cased with the hard of plastics and protects needle cap 12, and one end of needle handle 11 is solid It is scheduled on pintle 13, the pin chamber of needle handle 11 and the cavity conducting of pintle 13.

The most domestic disposable injection syringe used clinically is generally 20ml syringe, needs running into Inject the liquid medicine more than 20ml, or may result in defeated when repeatedly aspirating with injection of medicine Liquid bag leaks.Run into a bag liquid to add when multi-medicament is used for multiple times one pair of syringe aspirating drug and also may be used Make the crude rust of syringe needle, the acutance of image needle point, cause potential safety hazard.Medicine injection is taken out in turnover repeatedly, Being increased by the probability of needle sting, work efficiency decreases simultaneously.

Utility model content

For in prior art, syringe needle rust when syringe needle is injected repeatedly, transfusion bag leakage, potential safety hazard Big deficiency.

The utility model discloses a kind of arc needle handle formula injection needle, including:

Arc needle handle, described arc needle handle is fixed on pintle；

Rubber needle sheaths, described rubber needle sheaths is looped around outside arc needle handle；

Pintle, the cavity in described pintle turns on arc needle handle；

Serum cap, described serum cap is fixed on pintle.

Below the thickness 3mm of described rubber needle sheaths.

The extended length 10%～50% of described pintle.

The through hole of described serum cap gradually tapers up, and the narrowest place is positioned at the junction of serum cap and pintle.

Below curvature 0.05/cm of described arc needle handle.

This utility model syringe needle header structure is simple, reasonable, improves on original injection needle, system Make easily, low cost, easy to use, efficiently avoid drawing liquid injection repeatedly and cause the wave of medicinal liquid Taking and pollute, being difficult to make syringe needle rust, be not likely to produce transfusion bag leakage, potential safety hazard is little.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described further.

Embodiment 1:

A kind of arc needle handle formula injection needle, including: arc needle handle 1, arc needle handle 1 is fixed on pintle On 3；Rubber needle sheaths 2, rubber needle sheaths 2 is looped around outside arc needle handle 1；Pintle 3, in pintle 3 Cavity turn on arc needle handle 1；Serum cap 4, serum cap 4 is fixed on pintle 3.

The thickness 3mm of rubber needle sheaths 2.The extended length 10% of pintle 3.The through hole of serum cap 4 by Tapering contracting, the narrowest place is positioned at serum cap 4 and the junction of pintle 3.Curvature 0.05/cm of arc needle handle 1.

Directly being thrust by the syringe needle of arc needle handle 1 after sterilization transfusion bag mouth, pintle 3 is with serum cap 4 even Meet place upwards, injected by pintle 3 after taking 20ml syringe aspiration medicinal liquid.Inject and complete extract syringe, Retain needle Head, be again aspirated medicinal liquid and add at the rubber cap 4 of pintle 3, repeatedly can repeatedly, Owing to arc needle handle 1 is bending and opening upwards, therefore do not worry that medicinal liquid can overflow.Rubber cap 4 Can repeated localised puncture syringe needle, when this avoid repeatable operation in transfusion bag, generation leaks outside.It addition, Rotate pintle 3 angle variable, when needs extract liquid from transfusion bag, can opening pintle 3 Mouth is mobile to right side, goes back to top after extracting liquid out.

Below the preferred embodiment created this utility model is illustrated, but this practicality is new Type is created and is not limited to described embodiment, and those of ordinary skill in the art are new without prejudice to this practicality Modification or the replacement of all equivalents, these equivalent modifications can also be made on the premise of type creative spirit Or replacement is all contained in the application claim limited range.
