As shown in Figure 7, ampoule 4 comprises the first upper shield 13, cylindrical shell 14, check valve 15, the first sealing ring 16, the second upper shield 17, the first injection cover 18, the first spring 19 and spool 20.Piston rod 7 enters from cylindrical shell 14 rear ends, then fixing by the first upper shield 13, makes piston rod 7 and the first upper shield 13, cylindrical shell 14 energy relative slidings; Enter the upper end that medicine check valve 15 is arranged on cylindrical shell 14, enter medicine check valve 15 and be connected with medicine storage device 3 by flexible pipe; The front inner wall footpath of cylindrical shell 14 concaves, and projection section is embedded with the first sealing ring 16; First sprays cover 18 front ends protrudes, and centre has liquid outlet, and the first front end that sprays cover 18 withstands the first sealing ring 16, and rear end is embedded in the interior concave volume of cylindrical shell 14; First sprays that cover is provided with the first spring 19 in 18 and spool 20, the first springs 19 withstand spool 20.
Described spool 20 is that a rear end is that cone 202 and front end are the valve body of cylinder 201, is uniformly distributed two above grooves vertically on the circumference of cylinder 201, and the cross section of cylinder 201 is plum blossom-shaped, and cone 202 coordinates with the inner ring of the first sealing ring 16.
As shown in Figure 8, injection apparatus 1 comprises hand-held cylindrical shell 29, is provided with control knob 21 on housing 29, and the rear end of housing 29 is provided with bonnet 22, is provided with through hole in the middle of bonnet 22; In housing 29 tubular front ends, be provided with a cylindrical barrel 25, the rear end of cylindrical barrel 25 is provided with a liquid inlet joint, is the cone 24 with through hole, for external hose in liquid inlet joint; Liquid inlet joint outer race has the 3rd upper shield 23, the three upper shields 23 that link with cylindrical barrel 25 screw threads for compressing the flexible pipe joining with liquid inlet joint; The front end of cylindrical barrel 25 comprises the second sealing ring 26, the second injection cover 28 and quadruplet lid 27.
The front inner wall footpath of cylindrical barrel 25 concaves, and projection section is embedded with the second sealing ring 26; Second sprays cover 28 front end projections, and centre has spray orifice, and the second rear end of spraying cover 28 is embedded in the interior concave volume of cylindrical barrel 25, withstands the second sealing ring 26; Second sprays the protruding middle through hole of quadruplet lid 27 that passes of front end that overlaps 28, the second injection cover 28 is fixed with being threaded of cylindrical barrel 25 by quadruplet lid 27.
When injection apparatus 1 sprays, pressure is provided by piston rod 7 compressed liquids, enters into cylindrical barrel 25 inside from the high-speed jet out of ampoule liquid outlet by flexible pipe and cone liquid inlet joint 24, then sprays the small spray orifice of cover 28 front end by second and penetrates.
Medicine storage device 3 is fixed on injection apparatus 1 shell, and its outlet is connected with the check valve of the ampoule 4 of Power Drive Unit 2 by flexible pipe; Described medicine storage device 3 comprises is with graduated syringe, transfusion bag;
As shown in Fig. 2, Fig. 3 a and Fig. 3 b, whole equipment is when original state (before injection), voice coil motor 5 and piston rod 7 be not all in initial position (movement), now enters the pressure-acting that ball valve core 30 in medicine check valve 15 is subject to medicinal liquid and compress the second spring 31, and medicinal liquid enters into ampoule; In original state lower shell 14, do not compress medicinal liquid, spool 20 is because the first sealing ring 16 is close in the effect of the first spring 19 simultaneously, and between injection apparatus 1 and ampoule 4, passage is in closed state.
As shown in Fig. 4, Fig. 5 a and Fig. 5 b, in spraying completion status, (injection completes whole equipment, do not return), voice coil motor 5 and piston rod 7 are all in terminal position, now enter effect that the ball valve core 30 in medicine check valve 15 is compressed medicinal liquid and the second spring 31 by the channel seal between ampoule 4 and medicine storage device 3, medicinal liquid cannot enter into ampoule; In cylindrical shell 14, have compression medicinal liquid, spool 20 is because the first spring 19 is compressed in the effect of compression medicinal liquid simultaneously, and the passage between injection apparatus 1 and ampoule 4 is in opening state.
Work process of the present utility model is as follows:
Before injection, need first to place medicine storage device 3, be connected with check valve 15 by flexible pipe, due to fluid pressure effect, the spool 30 of check valve 15 compresses the second spring 31, and medicinal liquid enters cylindrical shell 14.
When injection, operator presses the control knob that is connected to control circuit 21 on hand-held cylindrical shell 29, control circuit is powered to voice coil motor 5 after receiving the signal that control knob 21 sends, in voice coil motor 5, the effect that tubular coil 10 is subject to electromagnetic force drives coil support 12 together to ampoule 4 direction motions.Because coupling cover 6 is connecting the piston rod 7 of voice coil motor 5 and ampoule 4, therefore, the athletic meeting of voice coil motor 5 promotes piston rod 7 and move in ampoule 4, thereby compressed liquid promotion spool 20 compresses the first spring 19, and medicinal liquid sprays from ampoule 4.In this course, because piston rod 7 advances, make ball valve core 30 closely cooperate with the inwall that is connected headband circular arc under the elastic force effect of the second spring 31, liquid cannot be back to Drug Storage;
Oppositely energising immediately after injection completes, tubular coil 10 is subject to the effect of reverse electromagnetic force, drives coil support 12 together to ampoule 4 motion in the other direction.Overlap 6 by coupling the piston rod in ampoule 47 retracted,
Now, due to the elastic force effect of the first spring 19, make spool 20 withstand the first sealing ring 16, the liquid in flexible pipe and injection apparatus 1 cannot be back to cylindrical shell 14; The ball valve core 30 of medicinal liquid pressure-acting in medicine storage device 3 in check valve 15 simultaneously, compression the second spring 31, medicinal liquid is drawn in the cylindrical shell 14 in ampoule 4.
In course of injection, because voice coil motor 5 rates of acceleration are very high, and can provide powerful power, therefore energising all can complete in moment with reverse energising.Piston rod 7 is threaded connection and is formed by threaded bar and piston head in addition, has like this to utilize to change not isometric ampoule.
Above-described embodiment is only for the design of the present utility model of explaining, but not restriction to this utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to this utility model, all should fall into protection domain of the present utility model.
