When this utility model uses, disposable syringe is placed in the outer casing underpart groove, the syringe urceolus is fixed in the outer casing underpart groove by self elastic force of spring leaf, and syringe push-pull bar top links to each other with the tooth bar bottom; When opening control circuit, through the relevant apparatus effect, just can control syringe piston and move up and down, thereby the control syringe sucks medicinal liquid or liquid medicine injection.Because this utility model can replace manual injection, for user brings convenience, so have good application prospect.
Description of drawings
Fig. 1 is this utility model structural representation and the use sketch map of disposable syringe on this utility model; Fig. 2 is the circuit diagram between this utility model control circuit and the motor.
The specific embodiment
Shown in Fig. 1, the motoring syringe device, consisted of by shell 2, control circuit 3, motor 4, reduction gearing 5, tooth bar 6, chute 7 and spring leaf 8, a groove is arranged at shell 2 bottoms, and control circuit 3, motor 4, reduction gearing 5 are installed in the shell 2, and chute 7 is installed in shell 2 right sides, tooth bar 6 is installed in the chute 7, tooth bar 6 tops and reduction gearing 5 engagements, spring leaf 8 is divided into two, is installed in respectively shell 2 lower recess the right and lefts.The 1st, disposable syringe.Control circuit 3 is by power supply, silicon rectifier diode, the integrated adjustable voltage stabilizer of three ends, electrochemical capacitor, ceramic disc capacitor, resistance, adjustable resistance and on and off switch form, connect by wire therebetween, adjustable resistance is installed in shell 2 when interior, its regulating handle is exposed at shell 2 outsides, is beneficial to outside shell 2 to regulate adjustable resistance by regulating handle, on and off switch is installed in shell 2 when interior, it is stirred handle be exposed at shell 2 outsides, be beneficial to outside shell 2, regulate on and off switch by stirring handle.Motor 4 is dc micro-motors, and the right-hand member of motor 4 axles has a gear.Reduction gearing 5 is comprised of small one and large one gear, and two gears are installed on the same axle, reduction gearing 5 be installed in shell 2 interior after, its left end gear wheel is positioned at shell 2, its right-hand member pinion is positioned at outside the shell 2.Spring leaf 8 is copper.When this utility model uses, disposable syringe 1 is placed in shell 2 lower recess, the urceolus of disposable syringe 1 is fixed in shell 2 lower recess by self elastic force of spring leaf 8, and the push-pull bar top of disposable syringe 1 links to each other with tooth bar 6 bottoms; When opening control circuit 3, the left and right directions of the on and off switch by stirring control circuit 3, just can control the rotation direction of motor 4, when stirring the on and off switch of control circuit 3 left, motor 4 turns round clockwise, by right-hand member gear driven reduction gearing 5 runnings of motor 4 axles, the tooth bar 6 that continues moves upward, and the push-pull bar that drives disposable syringe 1 moves upward, thereby disposable syringe 1 sucks medicinal liquid, the on and off switch of control circuit 3 closed after sucking medicinal liquid; When disposable syringe 1 needs injection, the on and off switch of control circuit 3 is stirred to the right, thereby motor 4 turns round counterclockwise, move downward through reduction gearing 5 band carry-over bars 6, continue it, the push-pull bar of disposable syringe 1 moves downward, so medicinal liquid is released; By the adjustable resistance resistance of adjusting control circuit 3, can control the rotating speed of motor 4, the control disposable syringe 1 that continues sucks and releases the speed of medicinal liquid.
Shown in Fig. 2, by power supply G, silicon rectifier diode VD1, VD2, the integrated adjustable voltage stabilizer A of three ends, electrochemical capacitor C2, ceramic disc capacitor C1, C3, resistance R, adjustable resistance RP and on and off switch SK composition control circuit.M is motor.After the power supply of G enters A, under the effect of peripheral cell VD1, VD2, C1, C2, C3, R and the RP of A, the size that just can regulate the A output voltage by the resistance of regulating RP.The power supply of A output enters 1,2 foot of SK, when SK stir handle left when stirring, the power supply that A exports enters M through 1,2 foot and 3,4 feet of SK, so M gets electric clockwise running; When SK stir handle to the right when stirring, the power supply of A output enters M through 1,2 foot and 5,6 feet of SK, because the mode of connection of 3,4 feet of the mode of connection of 5,6 feet of SK and M and SK and M is just in time opposite, so M gets electric counterclockwise running.
In Fig. 2, G is No. 7 batteries of 4 joints, and voltage is 6V; The A model is LM317; VD1, VD2 model are 1N4002; C1, C3 specification are 0.1UF, and the C2 specification is 20UF/50V, and the R resistance is 120 Ω; RP is the 4.7K adjustable resistance.
