Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in detail.This figure is the schematic diagram simplified, the most in a schematic way
Basic structure of the present utility model is described, therefore it only shows the composition relevant with this utility model.
Refer to shown in Fig. 1-Fig. 3, a kind of safe injection needle of the present utility model, it includes needle assembly and secure group
Part, needle assembly includes needle tubing seat 11 and is located at the needle tubing 12 of needle tubing seat 11 one end, and security component includes sleeve pipe 21 and elastic component
22。
Sleeve pipe 21 is sheathed on needle tubing 12, and sleeve pipe 21 can move along the length direction of needle tubing 12, one end of elastic component 22
Being fixed on sleeve pipe 21, the other end of elastic component 22 is fixed on needle tubing seat 11.
Safe injection needle of the present utility model is not when using, and due to the elastic force effect of elastic component 22, makes elastic component 22
Prop up sleeve pipe 21, and the complete sleeve in needle point position 21 of needle tubing 12 can be made to hide；In piercing process, needle tubing 12 enters blood
Pipe, sleeve pipe 21 is stayed external and close to needle tubing seat 11；When injection terminates, after pulling out pin, sleeve pipe 21 returns because of elastic component 22
Bullet effect, hide the needle point position at needle tubing 12 again, it is to avoid needle point accidentally injures patient or the generation of medical worker's situation.
Elastic component 22 is strip structure, near the side of needle tubing 12 along vertical with the axis of needle tubing 12 on elastic component 22
Direction offers groove 221, by arranging this groove 221, it is possible to guide the direction of elastic component 22 bending so that it is towards deviating from needle tubing
The direction bending of 12.
The quantity being appreciated that elastic component 22 is one, it is also possible to be two, in order to make elastic component 22 stable mobile, this
In embodiment, the quantity of elastic component 22 is two, and the two elastic component 22 is symmetrical arranged.
The material of elastic component 22 can be rubber, and this quality of materials is relatively light, be easily worked, be difficult to hurt sb.'s feelings, and is processed into
This is relatively low.
On sleeve pipe 21, the one end away from needle tubing seat 11 is provided with inclined plane 211, and this inclined plane 211 is during acupuncture treatment, pulling out pin
Can be with skin surface contact, it is simple to the stable movement of sleeve pipe 21.
The two ends of above-mentioned elastic component 22 are connected with sleeve pipe 21 and needle tubing seat 11 respectively by following design: security component is also
Including being located at first connector 23 of one end of elastic component 22 and being located at second connector 24 of the other end of elastic component 22, first
Connector 23 fixed cover is located on sleeve pipe 21, and the second connector 24 fixed cover is located on needle tubing seat 11.In order to improve installation effectiveness,
