Abstract

The invention discloses a syringe capable of quantitatively injecting drugs. As an injection check valve is arranged in the needle head seat, and the rehydration check valve is arranged in the connecting head, the syringe automatically replenishes the liquid medicine when the piston is driven to move to the right by rotating the motor, and the needle discharges the liquid medicine for injection when the piston is move to the left, and the liquid medicine can be continuously replenished by the medicine can connected with the connecting head, thereby overcoming the troubles of tedious extractionof the liquid medicine. The left and right distance between the second contact switch and the first contact switch is adjusted by rotating the adjusting screw, thereby limiting the stroke of the piston, that is, controlling the dosage. By installing power supply device, button switch and rotating motor to replace the traditional spring mechanical structure, the injection liquid and the replenishment liquid can be controlled by clicking button switch, the operation is easy, the fatigue degree of injecting a large number of fry is greatly reduced, and at the same time, the invention has the portable function. The invention is used for injecting fish-friendly drugs into fish fry farms.

Description

technical field [0001] The invention relates to the field of fish pond breeding, in particular to a syringe capable of quantitatively injecting medicine. Background technique [0002] For the injection of broodstock drugs in fish fry farms (for ripening, estrus, and spawning), the existing syringes are directly connected to the prepared drug bottles, and the workers determine the amount of drug injections based on years of experience and the size of the fish. Then It will result in the subjective amount of injection, which may not reach the amount you need to inject. Therefore, some injections are too little, and some injections are too much; and most of the fish fry farms are large-scale cultured, and large quantities of fry need to be injected. It is often not used several times when injecting through the volume in the existing needle tube, and frequent extractions are required. Liquid medicine, which increases the working intensity, and is currently injected through a co...
