The specific embodiment
In conjunction with specific embodiments the structure and the specific embodiment of the designed medical liquid dispenser of this utility model is described further with reference to the accompanying drawings below.
Medical liquid dispenser as shown in Figure 1 mainly is made up of housing 1, micromachine 2, actuating device, syringe 6, and housing 1 is made of loam cake 12 and outer housing, and as shown in Figure 4, loam cake 12 can be opened.Micromachine 2 and actuating device are positioned at housing 1, and micromachine 2 is the motor of band decelerator, the motion of control actuating device.Actuating device is made of synchronous pulley 3, driving-belt 10, leading screw 9 and feed screw nut 8.The on and off switch 5 of control micromachine 2 is positioned at housing 1 outside, micromachine 2 circumscripted power lines 13.Synchronous pulley 3 is installed on the output shaft of micromachine 2.Leading screw 9 is connected the location by bearing 11 with housing 1, and leading screw 9 and micromachine 2 relative sides also are equipped with synchronous pulley 3, by driving-belt 10 with 3 connections of two synchronous pulleys.Feed screw nut 8 matches with leading screw 9.The front end of feed screw nut 8 has draw-in groove 14, push rod 15 rear portions of syringe can be fixed, and push rod 15 has centre bore 18, and its aperture is greater than the external diameter of screw mandrel 9.The front end of housing 1 is axial deck 16, and its shape is used for fixing syringe 6 as shown in Figure 2.Axially deck 16 protection syringes 6 are coaxial with leading screw 9, and its rear portion has stopper slot 17, are used to cooperate fixedly injection tube 19, as shown in Figure 4.For the syringe needle that prevents syringe 6 comes off, axially the front end of deck 16 has needle stop 20, has the draw-in groove that is used for fixing syringe needle on it.The outside of housing 1 also has syringe ripping bar 7, as shown in Figure 3, is used for the convenient syringe 6 that takes out.
The control circuit of the micromachine 2 of this medical liquid dispenser as shown in Figure 5, mainly connected to form by no lock-switch J1, J2, capacitor C 1, two audion T1, T2 and resistance R 1～R5 and micromachine M, no lock-switch J1, J2 are the on and off switch 5 of micromachine M.Micromachine M is above-mentioned micromachine 2.Its operation principle is: audion T1 conducting after the energized, audion T2 turn-off.Micromachine M connects with audion T1, resistance R 1 and forms the loop, controls feed screw nut 8 by no lock-switch J1, J2 control motor positive and inverse and advances or retreat.After pressing no lock-switch J1, J1-1, J1-2 point is communicated with among Fig. 5, and micromachine M just changes, and feed screw nut 8 advances.Micromachine M stops operating after unclamping no lock-switch J1, press no lock-switch J2 after, J2-1, J2-2 point is communicated with among Fig. 5, micromachine M counter-rotating, feed screw nut 8 retreats.Micromachine M stops operating after unclamping no lock-switch J2.When micromachine M rotating band movable wire thick stick nut 8 was walked not have to terminal lock-switch J1, J2 and still stall disconnect to be taken place, the electric current that resistance R 1 is passed through increased sharply, and resistance R 1 current potential is raised, audion T2 conducting, and the current potential of audion T1 base stage descends, and audion T1 turn-offs.For preventing self-excitation, make audion T1, T2 keep the very little electric current of keeping by resistance R 2 feedbacks, thus protection micromachine M.
In use, as previously mentioned, by opening loam cake 12, to install and fix syringe 6 is mounted in the axial deck 16, the centre bore 18 of injector push-rod 15 cooperates with leading screw 9, the draw-in groove 14 of injector push-rod 15 rear portions and feed screw nut 8 front ends is fixing, injection tube 19 rear portions place in the stopper slot 17, syringe front end syringe needle position is fixed in the draw-in groove of needle stop 20, close the loam cake 12 of housing, the syringe needle of syringe 6 is inserted in the medicinal liquid that need be mixed, press the on and off switch 5 on the shell, micromachine 2 is rotated, drive leading screw 9 rotations in the medical liquid dispenser, feed screw nut 8 on it is moved, drive push rod 15 post-tensionings of syringe 6, medicinal liquid is sucked in the injection tube 19.Make micromachine 2 counter-rotatings by on and off switch 5 again, the push rod 15 of pushing syringe 6 advances, and the medicinal liquid in the syringe is injected in the invalid infusion bottle, by repeatedly inhaling, push away process, medicine is injected infusion bottle fast carry out dosing.Control on and off switch 5 can be controlled stopping of push rod 15 automatically or move.After treating that dosing is finished, open loam cake 12, move syringe ripping bar 7, syringe 6 can be released, take off syringe 6.Close loam cake 12, repeat said process, can carry out dosing next time again.
Find out that by above-mentioned this medical liquid dispenser structure is simpler, flexible operation, volume is little, makes weight lighter, uses more laborsavingly, and mechanical automatic liquid matching not only improves dosing speed thus, prevents liquid medicine contamination, and alleviates medical personnel's labor intensity greatly.
The medical liquid dispenser of this utility model can be widely used in health system.
