Description
Technical field
It is held the utility model relates to a kind of injection needle more particularly to a kind of insulin injection pen and unloads needle device.
Background technique
Novopen removes the tedious procedure that ward mate extracts insulin with syringe in insulin bottle from, can also remove disease from
The embarrassment of friendly insulin injection in public.The insulin injection pen is divided into disposable type and is recycled for multiple times
Type: the insulin injection pen of disposable type after use just throws away pen core and pen container together;Type is recycled for multiple times
Insulin injection pen needs replacing pen core and syringe needle after use, to avoid cross-infection.Existing insulin injection pen
Syringe needle is easy to stab operator during removing syringe needle after having injected insulin, stabs generated blood and is easy to make
At cross-infection, help injection if it is other people, this consequence will be more serious.Therefore need to improve existing insulin note
Penetrate the structure of a syringe needle.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of insulin syringe

Inner cavity communicates.
Further, the point is provided with flat groove, and the bottom surface of the groove is arc-shaped.
Further, the bottom surface of the groove is provided with several salient points.
The beneficial effects of the utility model are as described below: a kind of insulin syringe syringe needle removes outer needle cap before the injection
When, it pulls dynamic shield needle portion and moves back until being placed in retention bead in limiting slot, then shield needle portion drives sleeve part sliding straight
It is detached to outer needle cap and needle holder, the outer needle cap removed increases hand-held part to the distance at outer needle cap edge, after the completion of injection again
It is secondary that outer needle cap set is back in needle holder, it then turns needle holder and insulin injection pen and is detached from, since outer needle cap is being removed
The distance at hand-held part to edge is increased in the process, thus reduces the risk that operator is surprisingly stabbed;Sliding slot is set simultaneously
Meter reduce because outer needle cap lengthening and the space occupied volume, be conducive to pack.

Specific embodiment
The utility model is further described with reference to the accompanying drawing.
A kind of insulin injection pen as described in attached drawing 1 to 5, which is held, unloads needle device, including spike body 1, needle holder 2, interior needle
Cap 3 and outer needle cap 4;The needle holder 2 is step-like cylinder, and the spike body 1 is connected on the end face of needle holder 2, institute
Stating needle holder 2 is the cavity being open to other end, and is provided with screw thread, the open end of the needle holder 2 and injection of insulin
Pen is connected through a screw thread, and the interior needle cap 3 is arranged the outside for being connected to spike body 1, and is compressed on the end face of needle holder, institute
It states interior needle cap 3 and selects rubber elastic material, the outer needle cap 4 includes sleeve part 401 and protects needle portion 402, the shield needle portion 402
One end is slidably connected to the inside of sleeve part 401, and the sleeve part 401, which is arranged, is connected to the position that needle holder 2 is relatively large in diameter, institute
It states shield needle portion 402 to be arranged and be connected to the lesser position of 2 diameter of needle holder, the spike body 1 and interior needle cap 3 are set to outer needle cap
In 4 inner cavity.
401 inner cavity of sleeve part is ladder type hole, the cascaded surface of 401 inner cavity of sleeve part and the ladder of needle holder 2
Face is opposite to form sliding slot 403, and the one end in the shield needle portion 402 is slidably connected in sliding slot 403.
The sleeve part 401 is provided with limiting slot 410, and the cascaded surface of the limiting slot 410 close to 401 inner cavity of sleeve part is set
It sets, the shield needle portion 402 is provided with retention bead 411, and the connecting pin of the shield needle portion 402 and sleeve part 401 can be along cunning
Slot 403, which slides into, makes retention bead 411 and limiting slot 410 be cooperatively connected.Since syringe needle is disposable component, when shield needle portion
When being moved to retention bead 411 and the cooperation of limiting slot 410, retention bead will be connected in limiting slot always, protect the total of needle portion
