The specific embodiment
Referring to figs. 1 through Figure 11, conventional syringe comprises that syringe (11) inboard is provided with push rod (12), injection needle (15) is fixed on the one-piece type disposable syringe of injection needle on syringe (11) the front end injection needle fixed part (13) integratedly, and the detachable disposable syringe of injection needle that in use injection needle (15) is connected to injection needle fixed part (13).
This utility model is provided with in the syringe outside of conventional disposable syringe to be had along the cylinder type over cap (31) of syringe (11) slippage; there is anti-skidding prominent ring (32) in the outside of cylinder type over cap (31) front end; dismantle to be provided with behind the two side and plug together fixed part (33) up and down in the rear end; inner peripheral surface has a plurality of front projection (35) and a plurality of rear projection (36); the end that plugs together fixed part (33) up and down is connected to and is located at plugging together up and down on the fixed part (33) on syringe (11) the rear end handle (17); the prominent ring of stop (16) is arranged on the injection needle fixed part (13), have in the prominent ring of injection needle fixed part (13) and stop (16) is provided with being connected the prominent fixed adapter (21) that a plurality of (4～10) flexure strips (22) are arranged outside (23) that encircles.
Be used for cylinder type over cap (31) rearward end of syringe (11) outside slippage plug together fixed part (33) can insert syringe after the inboard inserting hole up and down (18) of Square handle (17); when with syringe (11) or cylinder type over cap (31) during to a sideway swivel, the lock-out state of inserting hole (18) just is disengaged up and down.
The instantiation of this moment is:
Plugging together of cylinder type over cap (31) rearward end the support chip (38) of rubber-like flexure strip (37) and band link slot (39) is set symmetrically on the fixed part (33), and between flexure strip (37) and support chip (38), groove (40) is set.
The both sides on syringe (11) surface are equipped with the triangle direction protrusion (11-1) that plugs together fixer (33) guiding for cylinder type over cap (31), and there are inclined plane (37-1), (38-1) of terminal taper in the end of flexure strip (37) and brace (38).
The symbol 20 that is illustrated in the picture is mounted in the piston seal (Picking) of push rod front end.
Effect to structure of the present utility model is elaborated below.
Conventional syringe comprises that injection needle (15) is fixed on syringe (11) front end integratedly---the injection needle unitary disposable syringe on the injection needle fixed part (13), and the detachable disposable syringe of injection needle that in use injection needle (15) is connected to injection needle fixed part (13).
Injection needle unitary disposable syringe is more common in small-sized (not enough 3cc) syringe, and the detachable disposable syringe of injection needle then is more common in big-and-middle-sized syringe.
The detachable disposable syringe of injection needle utilizes the mode of pushing that injection needle is inserted the injector syringe front end usually and fixes behind the injection needle fixed part one by one, perhaps at the injection needle fixed part screw type connecting portion is set, and the injection needle rotation is fixing.
This utility model can be applicable to detachable disposable syringe of injection needle and injection needle unitary disposable syringe simultaneously; on injector syringe (11), put earlier cylinder type over cap (31); then with cylinder type over cap (31) plug together up and down that fixed part (33) inserts in the inboard inserting hole (18) of syringe (11) back Square handle (17) and fixing, again fixed adapter (21) is connected to that injection needle fixed part (13) is gone up and fixing.
In this utility model; by promoting push rod (12) medicine in the injector syringe (11) is expelled in patient's body by injection needle (15); promote the cylinder type over cap (31) in syringe (11) outside then forward; injection needle (15) is moved up; again cylinder type over cap (31) is fixed to injection needle (15) top, the injection needle (15) of the syringe of finishing using with protection.
In this utility model, fixed adapter (21) is connected to the front end of injector syringe (11)---on the injection needle fixed part (13), because the prominent ring of inboard connection (23) is engaged with the prominent ring of stop (16) of injection needle fixed part (13), after fixed adapter (21) is fixed on the injection needle fixed part (13), fixing compact is difficult to break away from.
The fixed adapter (21) that is fixed on the injection needle fixed part (13) of injector syringe (11) front end has a plurality of (4～10) flexure strips (22), a plurality of flexure strips (22) rear side has retention tab (26), is inserted on the injection needle fixed part (13) and fixes.
Can go up slippage at syringe (11) after cylinder type over cap (31) is inserted well, 2 plugged together fixed part (33) about the rearward end of cylinder type over cap (31) had.
2 ends that plug together fixed part (33) insert in the inboard inserting hole (18) of syringe (11) back Square handle (17) and become one with syringe (11) up and down, the plugging together fixed part (33) and can insert like a cork in the inserting hole (18) of syringe (11) handle (17) and fix of the cylinder type over cap (31) that the triangle direction protrusion (11-1) by syringe (11) surface retreats.
Plug together after fixed part (33) is connected in the inserting hole (18); as long as rotational circle cartridge type over cap (31); just can from the inserting hole (18) of syringe (11) handle (17), separate out with plugging together fixed part (33); if while rotate plug together fixed part (33) forward (injection needle direction) push away cylinder type over cap (31), cylinder type over cap (31) will advance to injection needle (15) top.
Promptly; the support chip (38) of rubber-like flexure strip (37) and band link slot (39) is set on the fixed part (33) symmetrically plugging together of cylinder type over cap (31) rearward end; between flexure strip (37) and support chip (38), form groove (40); as long as to cylinder type over cap (31) application of force and rotation slightly; flexure strip (37) will be to groove (40) direction bending; cause under the state that originally is inserted into support chip (38) link slot (39); break away from cylinder type over cap (31) beginning slippage from the inserting hole (18) of syringe (11).
Till injection needle (15) the progressive cylinder type over cap of direction (31) advances to the inboard front projection (35) of cylinder type over cap (31) always and reaches the retention tab (26) at fixed adapter (21) rear; the application of force is with preceding the pushing away of cylinder type over cap (31) slightly; front projection (35) will be skipped the flexure strip (22) of fixed adapter (21); the front end of being close to flexure strip (22); rear projection (36) clings to the retention tab (26) at flexure strip (22) rear simultaneously; cylinder type over cap (31) can't move on or retreat, and is fixed tightly.
That is, after fixed adapter (21) was connected between inboard front projection (35) that forms with a determining deviation and the rear projection (36), progressive cylinder type over cap (31) stopped to move, and is fixed.
Cross syringe (11) advances to the cylinder type over cap (31) that the injection needle direction moves always; till the flexure strip (22) of the fixed adapter that is fixed to injection needle fixed part (13) (21) is connected between inboard front projection (35) of cylinder type over cap (31) and the rear projection (36); and fixed tightly; injection needle this moment (15) is well protected in cylinder type over cap (31) inside; because the effect of cylinder type over cap (31) can prevent that the injection needle (15) of the syringe that people were used from stabbing.
In this utility model; cylinder type over cap (31) is shifted onto injection needle (15) top of injector syringe (11) top; to cylinder type over cap (31) slightly the application of force be rotated; cylinder type over cap (31) will be removed like a cork with syringe (15) and be connected; therefore easy and simple to handle; even if having gloves on, also can separate like a cork and mobile cylinder type over cap.
