The fixed couple 106 in position of four equidistance in base station edge, it binds the animal through couple 106 to tie up the rope, lets the base station fix at the animal body surface, and the back of base station covers has the cushion, reduces the frictional force injury to the animal body surface.
Fig. 1 is an overall schematic view of a power injector. Before using the power injector, the injector 15 is filled with the medical fluid 16 and placed in the injector chamber, and the open end of the injector is locked by the locking needle 12 to fasten the injector in the injector chamber. The adjusting nut 7 on the medicine injection screw rod is adjusted to push the syringe piston 14 to the bottom of the syringe when the movable end of the medicine injection push rod 8 extends out to the maximum, and all the medicine liquid can be injected from the needle head. The adjusting nut 3 on the needle inserting screw rod is adjusted to ensure that the length of the needle head 17 extending out of the needle hole 18 meets the requirement of injection depth when the movable end of the needle inserting push rod 4 extends out of the longest.
Carrying out iodine disinfection and alcohol deiodination on the body surface of the animal to be injected, and then binding the fixed base station 1 on the body surface of the animal to ensure that the needle hole 18 is aligned to the body surface part after disinfection and deiodination.
Fig. 3 is an electrical schematic of the control unit. After the control unit 19 is started to be switched on and switched off, the control unit 19 delays for a certain time to give a driving signal to the needle inserting push rod 4, the movable end of the needle inserting push rod 4 extends to drive the medicine injection screw 6 to approach the base platform 1, and the needle head 17 gradually penetrates through the injection hole 18 to penetrate into the subcutaneous tissues of the animals. When the needle head penetrates into the deepest part of the animal skin, the movable end of the needle inserting push rod 4 presses the travel switch 5, so that the normally closed contact SQ1 in the travel switch 5 is disconnected, and the control unit 19 immediately stops giving a driving signal to the needle inserting push rod 4; at the same time the normally open contact SQ1 in the travel switch 5 is closed and the control unit 19 immediately gives a drive signal to the injection plunger 8. At this time, the movable end of the needle inserting push rod 4 stops extending, the movable end of the medicine injection push rod 8 begins extending to approach the fixed base station, the small baffle below the spring 9 is driven to push the piston rod 10 to move towards the base station, the piston 14 also slowly moves towards the base station, the medicine liquid 16 in the syringe needle cylinder 15 is extruded out of the needle head 17, and the medicine liquid is injected into the animal body.
When the movable end of the medicine injection push rod 8 extends to the longest, the piston 14 moves to the bottommost end of the injector, the liquid medicine 16 is injected completely, the small baffle plate below the spring 9 presses the travel switch 11 at the moment, the normally closed switch SQ2 in the travel switch 11 is disconnected, and the control unit respectively gives reverse driving signals to the needle insertion push rod 4 and the medicine injection push rod 8, so that the movable ends of the two electric push rods retract to the shortest position. And (5) after the whole injection process is finished, unfastening the bandage and taking down the power injector.
Control unit circuit diagram principle: when the main switch Q is manually closed, the normally closed contacts of the relays K1 and K2 are electrified, the needle inserting push rod motor M1 and the medicine injection push rod M2 are connected with reset driving signals, and after the movable end retracts to the shortest length, an internal circuit is disconnected (because the electric telescopic rod is internally provided with a travel switch). And then the injection button SB is started, the coil of the starting relay K0 is electrified and self-locked, the normally open contact K0 is closed, the coil of the time delay relay KT is electrified, the normally open contact KT of the KT is closed after a period of time, the coil of the needle inserting relay K1 is electrified, the two normally open contacts K1 are closed, the two normally closed contacts K1 are disconnected, the needle inserting push rod motor M1 is positively powered and driven, and the movable end of the needle inserting push rod is gradually extended. When the needle is extended to the longest position, the movable end triggers a travel switch SQ1 to act, a normally closed contact SQ1 of SQ1 is disconnected, the needle inserting push rod motor M1 is powered off and stops moving, and the movable end is located at the longest extending position. The normally open contact SQ1 is closed, the medicine injection relay K2 coil is electrified, the two normally open contacts K2 are closed, the normally closed contact K2 is disconnected, the medicine injection push rod motor M2 is positively powered and driven, and the movable end of the medicine injection push rod extends gradually. When the movable end of the medicine injection push rod extends to the longest, the travel switch SQ2 is triggered, the normally closed contact of SQ2 is disconnected, the starting relay K0 coil is powered off, the normally open contact K0 is disconnected, the delay relay KT coil is powered off, the normally open contact KT is disconnected, the needle insertion relay K1 coil is powered off, the normally open contact K1 is disconnected, the normally closed contact K1 is closed, the needle insertion push rod motor M1 is powered reversely, a reset driving signal is obtained, the movable end of the needle insertion push rod retracts to the shortest, and the travel switch is arranged inside the needle insertion push rod to enable the needle insertion push rod motor. At the moment, the travel switch SQ1 is reset, the normally open contact SQ1 is disconnected, the coil of the medicine injection relay K2 is powered off, the normally open contact K2 is disconnected, the normally closed contact K2 is closed, the medicine injection push rod motor M2 is powered on reversely, a reset driving signal is obtained, the movable end of the medicine injection push rod retracts to the shortest length, and the travel switch arranged inside the medicine injection push rod enables the medicine injection push rod to be powered off. The master switch Q is manually turned off and the injection process is ended.
