Adjustable precise continuous injector and use method thereof

Abstract

The invention discloses an adjustable precise continuous injector. The adjustable precise continuous injector comprises needle cylinders, a needle bed, an injection arm and an injection piston, and is characterized in that the needle cylinders comprise a first needle cylinder and a second needle cylinder, a liquid absorbing arm is arranged in the first needle cylinder, the top end of the liquid absorbing arm is connected with a liquid absorbing pull plate, the bottom end of the liquid absorbing arm is connected with the injection piston, the liquid absorbing arm is a ladder-shaped piston arm, a control device is arranged outside the second needle cylinder, the injection arm is arranged inside the second needle cylinder, the upper end of the injection arm is connected with an injection pressing plate, quantifying threads are arranged on the injection arm, the injection arm is connected with a second power device, a locator is further arranged in the second needle cylinder, one end of the locator is connected with a first power device, the other end of the locator extends into the first needle cylinder to be matched with a ladder-shaped piston, and a power supply device is arranged at the lower part of the second needle cylinder. The adjustable precise continuous injector has the advantages that the structure is simple, the use is convenient, the labor intensity is low, multiple times of injection can be carried out through one-time extraction of liquid medicine, the dosage can be rapidly adjusted at any time, the dosage is accurate, and the operation errors are small.

Description

technical field [0001] The invention relates to an adjustable precise continuous syringe and a method for using the same, belonging to the field of medical and veterinary equipment. Background technique [0002] When injecting a large number of animals, especially when carrying out epidemic prevention operations, it is necessary to repeatedly extract the anti-epidemic liquid for injection, which is highly repeatable. In view of the problems of high labor intensity and large repeatability, there is an urgent need for a simple structure and easy to use , Multiple injections can be completed quickly by extracting the liquid medicine once, and the dose of each injection can be accurately regulated, and the injection dose can be adjusted quickly at any time, so as to minimize the labor intensity of workers and reduce the repetitive labor of epidemic prevention injection operations. In the process of Chinese medicine experiment, animal experiment is the most commonly used experime...
