Medicament residue in syringe is in operator's body, or even causes allergy, transmission etc. possible.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point there is provided a kind of retractable needle syringes.
The technical scheme provided according to the utility model, retractable needle syringes, including syringe body and piston rod,
Piston rod is arranged inside syringe body, and piston rod can be moved back and forth in syringe body；Before syringe body
End is additionally provided with an injection port；The syringe body side is provided with independent cavity, in cavity provided with can retractable needles, can return
Shortening head can be moved back and forth in cavity, and be stretched out by injection port outside syringe body.
It is described can retractable needles include syringe needle, spring, sliding shoe, connecting rod and button；The syringe needle end and spring one end
Connection, the spring other end is connected with sliding shoe, and connecting rod is fixed on sliding shoe；Button is connected with one end of connecting rod.It is described
Separation layer is provided between spring and syringe needle, separation layer is closed by syringe needle, is of coupled connections between separation layer and cavity inner wall.
The syringe needle is made up of needle point and needle stand, and needle point is fixed on needle stand, and needle stand is connected with syringe body.
The cavity front end is provided with through hole, sideways provided with chute, and chute front end is provided with bayonet socket；The button is higher than chute,
It can move forward and backward, and be stuck at bayonet socket in chute.
The beneficial effects of the utility model：The utility model is simple in construction, passes through simple mechanical linkage and spring assembly
Control needle automatic retracting, greatly reduce and damage by mistake during syringe use, and avoid therefore caused by medicine it is residual
Stay, transmission etc..

Embodiment
As Figure 1-3：Retractable needle syringes, including syringe body 1 and piston rod 2, piston rod 2 are arranged at note
Inside emitter body 1, piston rod 2 can be moved back and forth in syringe body 1；The front end of syringe body 1 is additionally provided with one
Individual injection port 5；The side of syringe body 1 is provided with independent cavity 3, in cavity 3 provided with can retractable needles 4, can bounce back pin
First 4 can move back and forth in cavity 3, and be stretched out by injection port 5 outside syringe body 1.
It is described can retractable needles 4 include syringe needle 4-1, spring 4-2, sliding shoe 4-3, connecting rod 4-4 and button 4-5；The pin
Head 4-1 ends are connected with spring 4-2 one end, and the spring 4-2 other ends are connected with sliding shoe 4-3, and connecting rod 4-4 is fixed on sliding shoe 4-
On 3；Button 4-5 is connected with connecting rod 4-4 one end.
Separation layer 4-6 is provided between the spring 4-2 and syringe needle 4-1, separation layer 4-6 is closed by syringe needle 4-1, separation layer 4-
It is of coupled connections between 6 and the inwall of cavity 3.The syringe needle 4-1 is made up of needle point and needle stand, and needle point is fixed on needle stand, needle stand with
Syringe body 1 is connected.
The front end of cavity 3 is provided with through hole 3-1, sideways provided with chute 3-2, and chute 3-2 front ends are provided with bayonet socket 3-3；It is described
Button 4-5 is higher than chute 3-2, can be moved forward and backward in chute 3-2, and be stuck at bayonet socket 3-3.
When not in use, spring 4-2 is in relaxed state to the utility model, and syringe needle 4-1 is retracted in inside cavity 3, spring
4-2 one end is connected with syringe needle 4-1, and the other end is connected with sliding shoe 4-3；Now button 4-5 is located at chute 3-2 front ends, button 4-5
It is connected by connecting rod 4-4 with sliding shoe 4-3；
The utility model is in use, button 4-5 is pushed away forward along chute 3-2, and connecting rod 4-4 drives sliding shoe 4-3 to spring
4-2 is oppressed, and promotes syringe needle 4-1 to be stretched out by injection port 5 outside syringe body 1, now, button 4-5 is pushed to bayonet socket
At 3-3, pressing button 4-5 make its be connected to 3-3 pairs of bayonet socket can the component of retractable needles 4 be fixed so that syringe needle 4-1 ejection note
Loophole 5；By twitching the feed liquor of piston rod 2 backward, parenteral solution flows into needle stand by syringe needle 4-1 needle point, then by needle stand with
The connectivity part of syringe body 1 is flow to inside syringe body 1, realizes the process of feed liquor；
After feed liquor is finished, separation layer 4-6 presence ensures that parenteral solution only flows in syringe needle 4-1 and syringe body 1, no
