Description
Technical field
The utility model relates to a kind of syringes.
Background technique
Current syringe used in hospital includes syringe, syringe needle and needle cap three parts, leans on needle cap will under normal circumstances
Syringe needle is built to prevent damage, but because syringe needle and needle cap are too thin, more holds during returning set needle cap after having used syringe needle instead
Easily user is allowed to be damaged, and medical institutions uniformly collect in the case where syringe needle is usually in exposure at present, this
So that the staff collected is easy to damage oneself, and it is important that used syringe needle may have the blood of patient
Various infective virus in liquid.
Utility model content
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide a kind of syringe, the notes
The syringe needle of emitter automatically interior after syringe needle is detached from syringe can be reduced in needle guard.
For this purpose, syringe provided by the utility model, including syringe, syringe needle and needle guard, syringe needle and syringe is detachable leads
It connects, the needle guard front end is portalled with syringe needle, and syringe needle is set in needle guard, is provided between the syringe needle and needle guard and is promoted syringe needle
The flexible restoring organ that inside retraction syringe needle portals, the syringe needle not under by external force state interior retraction syringe needle portal with
Interior, the syringe needle connector sleeve inner hole connect and connects inner hole with the output end sleeve of syringe front end, and the needle guard and syringe are socketed,
The syringe needle connector sleeve inner hole is described in the syringe needle is ejected outward by syringe front end when connecting with the output end sleeve of syringe front end
Syringe needle portals.
The technical effect of the utility model: when the syringe needle of the syringe is not with syringe grafting, syringe needle is by flexible restoring organ
Effect retraction portal in the syringe needle of needle guard in, enclosure and protection of the syringe needle by needle guard, avoidable syringe needle stab people at this time, and
When syringe needle and needle guard and syringe are socketed, needle forward is simultaneously ejected syringe needle by the output end of syringe front end and the grafting of syringe needle connector sleeve
Other than portalling, it can be used for normal injection at this time.The syringe can avoid syringe needle from making under the premise of not influencing normal use
Manpower is stabbed after, and then disease caused by stabbing because of syringe needle is avoided to infect.
Detailed description of the invention
Fig. 1 is the separate structure schematic diagram for the syringe that the first embodiment of the utility model provides.
Fig. 2 is the structural schematic diagram under the syringe socket state in Fig. 1.

Specific embodiment
Referring to shown in Fig. 3, the syringe that the first embodiment of the utility model provides, including syringe 1, syringe needle 2 and needle guard
3, syringe needle 2 and syringe 1 is detachable connects, 3 front end of needle guard portals 4 with syringe needle, and syringe needle 2 is set in needle guard 3, described
The flexible restoring organ for promoting the inside retraction syringe needle of syringe needle 2 to portal 4, the elastic reset machine are provided between syringe needle 2 and needle guard 3
Structure includes that the ring-shaped step 7 that the lower ring catch 6 for being set to syringe needle connector sleeve 5,3 lower part of the needle guard have and covering connects in syringe needle
The pressure spring 8 of female connector 5,8 upper end of pressure spring withstand on 7 upper and lower end of ring-shaped step and withstand on lower ring catch 6;The syringe needle 2 is not by outer
Interior retraction syringe needle portals within 4 under power active state, and 9 sleeve of output end of 5 inner hole of syringe needle connector sleeve and 1 front end of syringe connects
Inner hole is connect and connects, the needle guard 3 is socketed with syringe 1,9 sleeve of output end of 5 inner hole of syringe needle connector sleeve and 1 front end of syringe
The syringe needle 2 ejects the syringe needle by 1 front end of syringe outward and portals 4 when connection.In the present embodiment, 1 front end of syringe have with
The delivery end 9 that syringe needle connector sleeve 5 is socketed, 9 periphery of delivery end are provided with socket tube 10, and the needle guard 3 connects with 10 sleeve of socket tube
Connect, 3 sleeve of needle guard when being connected on socket tube 10 delivery end overcome the pretightning force of the flexible restoring organ by institute
It states syringe needle 2 and is ejected forward the syringe needle of 10 front end of socket tube and portal other than 4, to ensure being bonded for needle guard 3 and socket tube 10: needle
It covers with latch 11 on 3 rear end inner walls, 10 outer wall of socket tube of the syringe 1 has and the matched annular slot of the latch 11
12, annular slot 12 have towards open front and for the notch 13 that latch is deviate from forward, the needle guard 3 is inserted in the socket tube
The latch 11 enters from the notch 13 when on 10, and the needle guard 3 completes the connection with the socket tube 10 after rotating.
Referring to shown in Fig. 3, needle guard 3 is dropped out when being detached from syringe 1 in order to avoid syringe needle 2,3 posterior medial of needle guard has ring
Shape block piece 14,14 center of ring catch have the centre bore 15 passed through for the output end 9 of the syringe 1, and the output end 9 is inserted
Enter the formation of syringe needle connector sleeve 5 to connect, the diameter for the lower ring catch 6 having on the syringe needle connector sleeve 5 is greater than in described
Heart hole 1 is to prevent syringe needle 2 from deviating from the needle guard 3 from rear portion.
