Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Core of the invention is to provide a kind of injection needle, which can be previously charged into automated injection device, and guarantees
Safety asepsis.Another core of the invention is to provide a kind of automated injection device including above-mentioned injection needle, can guarantee
One-touch automatic injection is realized on the basis of safety asepsis, manufacturing cost is low.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the cross-sectional view of injection needle specific embodiment provided by the present invention；Fig. 2 is Fig. 1 institute
Show the explosive view of injection needle.
The present invention provides a kind of injection needle, including needle stand 1 and the twolip needle body 2 being arranged on needle stand 1, in order to ensure twolip
The safety asepsis of needle body 2, one end of needle stand 1 are connected with the needle helmet 3 for the exposed peripheral part for being sheathed on 2 one end of twolip needle body, needle
The other end of seat 1 is equipped with the sealing film 4 for sealing the other end of twolip needle body 2, and twolip needle body 2 is fully sealed.
That is, the present invention realizes the sealing at 2 both ends of twolip needle body by needle helmet 3 and sealing film 4 respectively, and combine
Needle stand 1 achieve the effect that twolip needle body 2 is hermetically sealed.
It is understood that in order to avoid twolip needle body 2 during storage due to the gas leakage or infiltration etc. of junction
And get rusty or aoxidize, it is tightly connected between needle stand 1 and needle helmet 3 and between needle stand 1 and sealing film 4, the present embodiment is to needle
The specific connection type and connection structure of seat 1 and needle helmet 3 and needle stand 1 and sealing film 4 without limitation, as long as can guarantee to connect
Connect the leakproofness at place.
It should be noted that injection needle of the invention is mainly used for being installed in automated injection device, automatic injection is realized
The one-touch automatic injection of device.That is, user only needs to buy the automated injection device of integral type, it is not necessarily to autonomous group
Dress, in use, directly triggering the brake component of automated injection device.After triggering brake component, brake component pushes linkage structure, makes
Injection needle is connected to the clamped bottle being located in automated injection device first, and final lancet helmet 3, to realize injection.
As can be seen that the one-touch automatic injection in order to realize automated injection device, the both ends of injection needle are both needed to have thorn
Function is worn, therefore, the present invention uses twolip needle body 2, so that one end of twolip needle body 2 can pierce through the mouth cylindrical part of clamped bottle, it is real
The clamping and conducting of existing itself and clamped bottle, the other end can pierce through needle helmet 3, to realize final function of injection.
It is understood that needle helmet 3 be elastic component, with twolip needle body 2 pierce through needle helmet 3 after and continue Forward when,
Needle helmet 3 can be shunk under the extruding of automated injection device front end component, keep the dispensing end of twolip needle body 2 exposed, to complete
Final injection.
Preferably, needle helmet 3 is rubber parts, and rubber parts has elasticity, under the extruding of automated injection device front end component
Stacking can be shunk, to keep the dispensing end of twolip needle body 2 exposed.
Similarly, sealing film 4 is pierceable sealing film 4.
In addition, twolip needle body 2 and the position of needle stand 1 keep relatively fixed frictional force between twolip needle body 2 and needle stand 1
Should be greater than or equal to STATEMENT OF FEDERALLY SPONSORED driving force, to avoid twolip needle body 2 pierce through clamped bottle mouth cylindrical part or needle helmet 3 when it is opposite
Needle stand 1 skids.
It is understood that twolip needle body 2 be arranged needle helmet 3 one end be dispensing end, twolip needle body 2 towards sealing film 4
One end be medical fluid conduction terminal for being docked with clamped bottle.
In conclusion injection needle provided by the invention, needle helmet 3 can protect twolip needle body 2 exposed outside needle stand 1
The peripheral part of one end, sealing film 4 can protect the other end of twolip needle body 2, needle helmet 3 and sealing film 4 and combine needle stand 1 can be with
The integral sealing of twolip needle body 2 is realized, to ensure the safety asepsis of twolip needle body 2.Therefore, it is applied to certainly when by the injection needle
When dynamic injection device, the clamped bottle and injection needle being previously charged into automated injection device are able to maintain respective independence and packet
Integrality is filled, and since the both ends of twolip needle body 2 all have puncture function, and needle helmet 3 is elastic component, therefore, is being started certainly
After dynamic injection device, twolip needle body 2 can successively pierce through the mouth cylindrical part and needle helmet 3 of clamped bottle, and finally realize injection.
Compared with the prior art, injection needle of the invention can be previously charged into automated injection device, and guarantee safety asepsis
Property, therefore, when being applied to automated injection device, automated injection device can be realized on the basis of guaranteeing safety asepsis
One-touch automatic injection；Meanwhile the injection needle can be adapted to existing most of clamped bottle packaging drugs in the market, without pre-
Encapsulating needle technique, it therefore reduces the limitation that drug uses, while reducing the manufacturing cost of medical instruments combination assembly.

3 are set in the peripheral part of needle body fixed part 11, and after the peripheral part of needle body fixed part 11 is set in place, due to needle helmet 3
Tighten the sealed connection for realizing needle helmet 3 and needle body fixed part 11.
In order to further increase leakproofness, changed by the concave-convex fitting connection between needle helmet 3 and needle body fixed part 11
Become the cooperation path of the two, increases matching area, to make sealing effect more preferably.
In view of simple and the being easy to implement property of needle helmet 3 and the connection structure of needle stand 1, on the basis of above-described embodiment
On, the peripheral part of needle body fixed part 11 is equipped with groove 111, and the inner peripheral portion of needle helmet 3 is equipped with for sealing cooperation with groove 111
Interior protuberance.
Interior protuberance is preferably flange collar, correspondingly, groove 111 is annular groove.
When needle helmet 3 is connect with needle body fixed part 11, the interior protuberance insertion needle body fixed part 11 of the inner peripheral portion of needle helmet 3
In the groove 111 of peripheral part, the sealed connection of the two is realized.
In view of when by the injection needle be applied to automated injection device when needle stand 1 and automated injection device connection type,
