The present invention discloses a kind of anti-needle and stabs wound syringe needle, is made of spring arrangement and needle apparatus, spring arrangement covers on needle apparatus, and spring arrangement lower end is fixed in needle apparatus lower end；Original state, spring arrangement is retracted mode, and upper cover is threadedly coupled on the fixed base, and spring is compressive state, syringe needle is exposed, syringe needle fixing seat is mounted on the nipple of syringe by medical staff, after medical staff has used syringe, unscrewed upper cover, upper cover and firm banking are separated, spring drives upper cover to bounce, and upper cover wraps up syringe needle, prevents needlestick injuries medical staff.The configuration of the present invention is simple, easily manufactured, easy to use, low cost does not change syringe construction, and medical worker is facilitated to use, and protects user's use front and back not by the danger that syringe needle stabs wound or infectious disease infects, needlestick injuries staff when being also prevented from syringe processing.
Description
Technical field
The present invention relates to a kind of medical instrument, in particular to a kind of anti-needle stabs wound 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 wound 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 there is the anti-syringe for stabbing wound function still without retrieving syringe needle itself.
Summary of the invention
The invention aims to solve in above-mentioned background technique, not anti-needle stabs wound syringe needle, and the existing anti-needle of syringe is perverse
Hurt function to be mainly reflected on injector syringe rather than on syringe needle, apparatus structure is complicated, manufacture is cumbersome, cost is high, cannot
It is sufficiently used for clinic, existing syringe still can not protect user's use front and back to stab wound or be infected the danger that disease infects by syringe needle
Danger, it is unhealthful or the problems such as cause life danger, and a kind of anti-needle is provided and stabs wound syringe needle.The present invention places at pintle for the first time
Elastic device, as long as light motivation is closed after the completion of injection, protective device automatic spring, by syringe needle it is fully wrapped around including, needle point
Portion is not exposed, and present invention process is simple, low cost is easily realized, medical worker is facilitated to use, do not change the advantages that syringe construction.
A kind of anti-needle stabs wound 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 of the invention and process：
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.
Beneficial effects of the present invention：
The configuration of the present invention is simple, easily manufactured, easy to use, low cost does not change syringe construction, facilitates medical worker
It uses, protects user's use front and back not by the danger that syringe needle stabs wound or infectious disease infects, syringe needle when being also prevented from syringe processing
Stab staff.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of retracted mode of the present invention.
Fig. 2 is the stereoscopic schematic diagram of opening state of the present invention.
Fig. 3 is stereoscopic schematic diagram when the invention works.
Fig. 4 is the stereoscopic schematic diagram when present invention uses.
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 wound syringe needle,
Composition, 1 set of spring arrangement on needle apparatus 2, and 1 lower end of spring arrangement is fixed in 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
It closes；
