Description
Technical field
It the utility model is related to injection needle technical field, and in particular to a kind of Anti-stabbing injection needle.
Background technology
Injection needle is a kind of common medical instruments, and early in the 15th century, Italian's Ka Di Nellies just propose injection needle
Principle.Early in the 15th century, Italian Ka Di Nellies just propose the principle of injection needle.But until British Danny Boyles in 1657 and
Reyn has just carried out first time human trial.The French King Louis XVI（1774-1792 is in place）Army surgeon Ah
Bel is also it is contemplated that go out a kind of piston type injection needle.But it is believed that the pula of France it is fertile be hereby injection needle inventor.He
In the injection needle that 1853 supervise made of silver, capacity only has 1 milliliter, and has a screwed piston rod.
British Cathy Ferguson first uses Glass syringe pin.Glass transparent degree is good, it can be seen that injects the situation of medicine.
Hereafter have glass tube metal and use made of injection needle, can be sterilized with boiling method, syringe needle can also sharpening use and sterilize again.Now
Injection needle is made of plastic, and with once throwing away, greatly reduces the danger infected during injection.In order to ensure to defend
It is raw, cross-infection is prevented, contemporary injection needle uses plastic material more.
The scientific instrument that injection needle can be used in Medical Devices, container, such as some chromatographies are noted through diaphragm of rubber
Penetrate.Air embolism will be caused by directing injection of the gas into blood vessel.From injection needle remove air with avoid the method for embolism be by
Injection needle is inverted, gently beats and then a little liquid is extruded before blood flow is expelled to.
In some precision rather than the occasion of germ overriding concern problem, in quantitative chemical analysis, due to Glass syringe
The error of pin is smaller, push rod gliding smoothing is so still using.Can also when cooking carnivorous with injection needle toward noting in meat
Enter some juice to improve taste and quality, or be injected into when bakeing in cake.Ink can also be filled into by injection needle
In print cartridge.
Clinically medical personnel after filling medicament, are abandoning used injection needle to patient's intramuscular injection, into liquid bottles
When, exposed sharp needle easily stabs medical personnel, it is not intended in pricking wound be enough the skin injury for causing the wounded's bleeding,
And contaminated needlestick injuries are that various viral important routes of transmission are infected in hospital, and easily form cross-infection；In addition,
Also some illegal manufacturers reuse the injection needle after use, and patient is caused serious injury.Make in the market
Injection needles does not possess safeguard function, have safeguard function injection needles using it is loaded down with trivial details, manufacturing cost is higher,
It is unfavorable for promoting the use of.
Utility model content
The purpose of this utility model is to provide a kind of Anti-stabbing injection needle, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：
A kind of Anti-stabbing injection needle, including needle tubing and push rod, described push rod one end are connected with plug, the left end of the needle tubing
Provided with some acupunctures, the left end of the needle tubing is fixed with connecting portion, and external screw thread, the company are provided with the lateral wall of connecting portion
Some anti-rotations projections, in addition to needle guard are evenly arranged with the right part lateral wall of socket part, is provided with needle guard right part madial wall interior
Screw thread, rack is fixed with the madial wall of the needle guard rightmost side.
It is as the utility model further effect：The needle guard internal diameter is equal to connecting portion external diameter.
As the utility model, further effect is：The rack is fixedly installed on the madial wall of needle guard in annular shape
On.
As the utility model, further effect is：The anti-rotation projection is in arc-shaped.
As the utility model, further effect is：The raised rotation direction all same of the anti-rotation.
The beneficial effects of the utility model are after injection needle use terminates, and needle guard right part is enclosed on the outside of connecting portion, and
It is engaged by screw thread, meanwhile, with the continuous screw-in of needle guard, rack is engaged with anti-rotation projection so that needle guard can not be reverse
Rotate, then permanent be engaged with needle tubing of needle guard and can not screw off, so as to effectively protect the safety of medical personnel, and will not
Reused by criminal, effectively reduce the infection probability of disease.
