Description
Technical field
The present invention relates to medical device technology field, be specifically related to a kind of safe injection needle.
Background technology
Safe re-use preventing once-used syringe is widely used in medical field, avoids and uses unhygienic syringe and the viral cross infection that produces.But common disposable syringe causes certain operations person carry out secondary use or repeatedly use due to the problem of structure, the violation operation of user produces cross infection, reuse to stop artificial recovery, people arrange self-desttruction equipment in disposable ordinary syringe.But, although re-use preventing once-used syringe can prevent reusing of syringe, but syringe produces many inconvenience because entry needle exposes the syringe making to discard after using in the processes such as collection, transport, process, still likely stab medical worker and its related personnel, cause the cross infection of virus and bacteria.
Therefore, designing a kind of safe injection needle for protecting entry needle, is the urgent needs in current market.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the object of this invention is to provide a kind of safe injection needle, and this safe injection needle can be accomplished to use by secondary, can not cross infection; In last handling process, syringe needle is protected, not easily scratch people, be conducive to the healthy of people, and product manufacturing is easy, cheap, highly versatile, to meet user demand.
Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is as follows:
A kind of safe injection needle, comprises syringe needle, needle guard, needle holder and safe needle sleeve; Described safe needle sleeve comprises the sleeve for entangling syringe needle, and sleeve is provided with cylinder and the thin slice for fastening syringe needle; Described needle holder comprises the syringe needle link, safe needle sleeve linkage section and the female cone tip side that link into an integrated entity; Described needle guard is socketed on syringe needle link; Described cylinder is connected with safe needle sleeve linkage section; The syringe link of described female cone tip side and peripheral hardware is connected.
Described sleeve bottom end is connected with cylinder by snak link, and sleeve is provided with grab, cylinder is provided with grab with the use of hole clipping.
Described safe needle sleeve linkage section is provided with outer frosted tongue and groove, frosted tongue and groove in matching with outer frosted tongue and groove on described cylinder inner wall.Guarantee that needle holder and safe needle sleeve do not slide easily and can rotate the direction regulating needle point pipe gently, easy to use.
Described safe needle sleeve linkage section is provided with the centring ring of cylinder, is not separated for the cylinder on safe needle sleeve is fixed on safe needle sleeve linkage section.
Described square sheet is located in the intermediate inner wall of sleeve.
The joint of described needle holder female cone joint is 6:100 joint.
Described safe needle sleeve barrel bore is at 6.45mm, and the external diameter of needle holder safety shield linkage section is 6.42mm, cooperatively interacts between the two and does not slide easily.
Beneficial effect: safe injection needle of the present invention, simply rational in infrastructure, can accomplish to use by secondary, can not cross infection; In last handling process; syringe needle is protected; not easily scratch people, be conducive to the healthy of people, and product manufacturing is easy, cheap; use safety; not only can join screw syringe and can also join socket syringe, make the syringe of various kind can join safe needle sleeve, highly versatile; there is good practicality, good economic benefit and social benefit can be produced.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, safe injection needle comprises the syringe needle, needle guard 1, needle holder 2 and the safe needle sleeve 3 that are used in conjunction with each other.
The body of safe needle sleeve is a sleeve 9, establish grab 7 in the bottom of sleeve 9, be connected with cylinder 5 by shell fragment 6 at the bottom margin of sleeve 9, guarantee sleeve 9 can on the position of 180 ° up and down of cylinder 5 resilient movement, cylinder 5 is established hole clipping 14, for clamping thus fixed muffle 9 with grab 7; Sleeve 9, for entangling syringe needle, is protected syringe needle, and sleeve 9 is provided with the square sheet 4 for fastening syringe needle, and square sheet 4 is preferably located in the intermediate inner wall of sleeve 9.Cylinder 5 inwall is provided with interior frosted tongue and groove 10.
Needle holder 2 comprises syringe needle adhesive section 11, safe needle sleeve linkage section 12 and female cone tip side 13, and the female cone joint of female cone tip side 13 is 6:100 joint.Safe needle sleeve linkage section 12 being provided with outer frosted tongue and groove 15, being provided with below frosted tongue and groove 15 outside for cylinder 5 being fixed on unseparated centring ring 8 on safe needle sleeve linkage section 12.In version, syringe needle adhesive section 11, safe needle sleeve linkage section 12 and female cone tip side 13 adopt integral structure, easy to manufacture, sound construction.Outer frosted tongue and groove 15 matches with interior frosted tongue and groove 10, guarantees that needle holder and safe needle sleeve do not slide easily and can rotate the direction regulating needle point pipe gently, easy to use.Wherein, cylinder 5 internal diameter is 6.45mm, and the external diameter of needle holder safety shield linkage section 12 is 6.42mm, cooperatively interacts between the two and do not slide easily during connection.
The use procedure of this safe injection needle is: the front end 1, first this type safe injection needle being connected on syringe, uses the injection drug needed for syringe extraction, injects; 2, after injection, close safe needle sleeve, makes square sheet in sleeve block syringe needle, reach safeguard protection object.
