Description
Technical field
The utility model relates to a kind of medical instrument, in particular to a kind of anti-needle stabs syringe needle.
Background technique
Most common medical instrument is syringe in clinical treatment nursing process, it be a variety of administrations must with object,
Such as intravenous injection, intramuscular injection, intracardiac injection, acupoint injection therapy, subcutaneous injection and intracutaneous injection are required using syringe, and
The syringe needle of front end of the syringe needle is also the instrument that medical staff's injury is caused in use process, on the one hand it is the good side of human administration
Hand, on the other hand also endanger user, while stabbing medical worker because use after injection needle on, in addition to medical fluid
Except, it is also possible to blood, body fluid, the tissue etc. of the virus such as hepatitis B, AIDS for having patient to carry can cause hospital-acquired infection.One
Since secondary property syringe asks city, the approach of progress reform experienced the first generation, complete pumping function, the second generation except completion is taken out
It inhales outside function, makes syringe after use after completion syringe and may be at self-destructed state, the third generation and forth generation injection
Device: the safeguard protection to injection needle is realized for the first time；The concept that syringe and injection needle are integrated is realized for the first time；It is put forward for the first time
Use the design theory after syringe in injection needle automatic retracted to syringe；Applied compression spring realizes oneself of syringe for the first time
It ruins and safeguard protection, and is automatic protection.So far the 5th generation syringe asks city not yet.Although the third generation and forth generation just like
This function but do not approved by market because its manufacture is cumbersome, cost is high, be difficult to accomplish to be commercialized, while also increasing patient medical and taking
With and waste health resources.Up to the present still without retrieve syringe needle itself have Anti-stabbing function syringe.
Summary of the invention
The purpose of this utility model is solved in above-mentioned background technique, and not anti-needle stabs syringe needle, and existing syringe is anti-
Needle is stabbed function and is mainly reflected on injector syringe rather than on syringe needle, apparatus structure is complicated, manufacture is cumbersome, cost is high,
It cannot be sufficiently used for clinic, existing syringe is infected before and after still can not protecting user's use by needlestick injuries or infected disease
Danger, it is unhealthful or the problems such as cause life danger, and a kind of anti-needle is provided and stabs syringe needle.The utility model is for the first time in needle
Elastic device is placed at bolt, as long as light motivation is closed after the completion of injection, syringe needle is completely encapsulated in by protective device automatic spring
Interior, needle tip is not exposed, and the utility model simple process, low cost are easily realized, medical worker facilitated to use, do not change syringe
The advantages that structure.
A kind of anti-needle stabs syringe needle, is made of spring arrangement and needle apparatus, spring arrangement covers pintle side close in syringe needle
On device, and spring arrangement lower end is fixed at needle apparatus lower end；
The spring arrangement includes firm banking, spring and upper cover, and upper cover is threadedly coupled on the fixed base, firm banking
Outside has external screw thread, has internal screw thread inside upper cover, and lower spring end is fixedly installed on the fixed base, and upper end is arranged in upper cover
It is interior, and can the rotation in upper cover, internal screw thread matches with external screw thread；
The needle apparatus includes syringe needle and syringe needle fixing seat, and syringe needle is fixed in syringe needle fixing seat, and internal
It is connected, firm banking is fixed in syringe needle fixing seat, and spring pocket is outside syringe needle.
The working principle and process of the utility model:
Original state, spring arrangement are retracted mode, and upper cover is threadedly coupled on the fixed base, and spring is compressive state,
Syringe needle (needle point obstructs with needle) is exposed, and syringe needle (pintle) is mounted on the nipple of syringe by medical staff, when medical staff uses
After complete syringe, unscrewed upper cover separates upper cover and firm banking, and spring drives upper cover to bounce, and upper cover wraps up syringe needle, prevents
Needlestick injuries medical staff.
The utility model has the beneficial effects that
The utility model structure is simple, easily manufactured, easy to use, and low cost does not change syringe construction, facilitates medical matters
Personnel use, and the danger not infected by needlestick injuries or infectious disease before and after user's use are protected, when being also prevented from syringe processing
Needlestick injuries staff.

Specific embodiment
It please refers to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, it is by spring arrangement 1 and needle apparatus 2 that a kind of anti-needle, which stabs syringe needle,
Composition, 1 set of spring arrangement on needle apparatus 2, and 1 lower end of spring arrangement be fixed at 2 lower end of needle apparatus i.e. needle obstruct
Lower end；
The spring arrangement 1 includes firm banking 11, spring 12 and upper cover 13, and upper cover 13 is threaded in firm banking 11
On, there is external screw thread 111 outside firm banking 11, there is internal screw thread 131 inside upper cover 13,12 lower end of spring is fixed at
Determine on pedestal 11, upper end is arranged in upper cover 13, and can the rotation in upper cover 13, internal screw thread 131 and the matching of external screw thread 111
