Description
Technical field
The present invention relates to a kind of syringes.
Background technology
Current syringe used in hospital includes syringe, syringe needle and needle cap three parts, under normal circumstances will by needle cap
Syringe needle is built to prevent damage, but because syringe needle and needle cap are too thin, is more held during returning set needle cap after syringe needle has been used instead
Easily user is allowed to be damaged, and medical institutions uniformly collect in the case of syringe needle usually is in exposure at present, this
So that the staff collected is easy to damage oneself, and it is important that used syringe needle may carry the blood of patient
Various infective virus in liquid.
Invention content
In view of the deficiency of background technology, the technical problems to be solved by the invention are to provide a kind of syringe, the syringe
Syringe needle can it is automatic after syringe needle is detached from syringe in be reduced in needle guard.
For this purpose, syringe provided by the invention, including syringe, syringe needle and needle guard, syringe needle and syringe is detachable connects, institute
It states needle guard front end with syringe needle to portal, syringe needle is set in needle guard, is provided between the syringe needle and needle guard and is promoted syringe needle inside
The flexible restoring organ that retraction syringe needle portals, the syringe needle is not within interior retraction syringe needle portals under by external force active state, institute
It states syringe needle connector sleeve endoporus to connect with the output terminal sleeve of syringe front end and connect endoporus, the needle guard is socketed with syringe, described
The syringe needle ejects the syringe needle outward by syringe front end when syringe needle connector sleeve endoporus is connect with the output terminal sleeve of syringe front end
Portal.
The technique effect of the present invention：When the syringe needle of the syringe is not with syringe grafting, syringe needle is made by flexible restoring organ
In being portalled with retraction in the syringe needle of needle guard, syringe needle can be avoided syringe needle from stabbing people by the encirclement and protection of needle guard at this time, and in needle
When head and needle guard are socketed with syringe, the output terminal of syringe front end portals with the grafting of syringe needle connector sleeve and by needle forward ejection syringe needle
In addition, at this time available for normal injection.The syringe can avoid syringe needle after use under the premise of normal use is not influenced
Human hand is stabbed, and then the disease caused by syringe needle stabs is avoided to infect.

Portalled within 4 with retraction syringe needle interior under state, 5 endoporus of syringe needle connector sleeve is connect simultaneously with 9 sleeve of output terminal of 1 front end of syringe
Endoporus is connected, the needle guard 3 is socketed with syringe 1, and 5 endoporus of syringe needle connector sleeve is connect with 9 sleeve of output terminal of 1 front end of syringe
Shi Suoshu syringe needles 2 eject the syringe needle by 1 front end of syringe and portal 4 outward.In the present embodiment, 1 front end of syringe carries and syringe needle
The delivery end 9 that connector sleeve 5 is socketed, 9 periphery of delivery end are provided with socket tube 10, and the needle guard 3 is connect with 10 sleeve of socket tube, institute
It states delivery end when 3 sleeve of needle guard is connected on socket tube 10 and overcomes the pretightning force of the flexible restoring organ by the syringe needle
2 syringe needles for being ejected forward 10 front end of socket tube portal other than 4, to ensure being bonded for needle guard 3 and socket tube 10：After needle guard 3
It holds and is carried and the 11 matched annular slot 12 of latch, ring with latch 11,10 outer wall of socket tube of the syringe 1 on inner wall
Shape card slot 12 carry towards open front and for the notch 13 that latch is deviate from forward, the needle guard 3 is inserted on the socket tube 10
Shi Suoshu latches 11 enter at the notch 13, and the needle guard 3 completes the connection with the socket tube 10 after rotating..
With reference 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 carries ring
Shape block piece 14,14 center of ring catch carry the centre bore 15 passed through for the output terminal 9 of the syringe 1, and the output terminal 9 is inserted
Enter the syringe needle connector sleeve 5 formation to connect, the diameter of lower ring catch 6 carried on the syringe needle connector sleeve 5 be more than it is described in
Heart hole 1 is to prevent syringe needle 2 from deviating from the needle guard 3 from rear portion.
