Portable veterinary injection device capable of achieving batch injection and simultaneous color spraying and marking

Abstract

The invention discloses a portable veterinary injection device capable of achieving batch injection and simultaneous color spraying and marking, and belongs to the technical field of veterinary medical instruments. The portable veterinary injection device capable of achieving batch injection and simultaneous color spraying and marking is characterized in that an injection barrel with scales and a color spraying barrel are arranged in a protective sleeve, one end of the protective sleeve is provided with a syringe needle locking sleeve and a first through hole, the syringe needle locking sleeve is provided with a through hole, the through hole in the syringe needle locking sleeve is communicated with the through hole in the protective sleeve, a first small steel ball with holes is arranged between the first through hole in the protective sleeve and the through hole in the syringe needle locking sleeve, the first small steel ball with the holes can be located at the position of the first through hole in the protective sleeve and cannot penetrate through the first through hole in the protective sleeve, a piston is arranged in the injection barrel with the scales and connected with a piston rod, a reset spring is arranged between one end of the piston rod and one end of the protective sleeve, and the piston rod is of a hollow structure.

Description

technical field [0001] The invention relates to a portable veterinary injection device capable of batch injection and simultaneous color spraying and marking, belonging to the technical field of veterinary medical devices. Background technique [0002] The injection of animal vaccines is usually difficult because the animal is always struggling, which makes the injection difficult. In the Chinese patent CN201519210U authorized and announced on July 7, 2010, a continuous veterinary syringe is disclosed, which includes a medicine bottle, a drug delivery tube, a needle tube, a needle head, a hook-shaped syringe pad, a parallel check valve, a vertical check valve Return valve, syringe sleeve, syringe, zigzag positioning bar, positioning piece, handle, return spring, medicine pushing piston, snap reed, metering positioning bolt, etc., the drug delivery device is on the upper part of the injection cavity, The drug tube is connected. Although the above-mentioned syringe does not ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned syringe does not need to add medicine in the middle, its disadvantage is that the connection between the medicine bottle and the injection tube located above the injection tube is easy to break, and the syringe is easy to be top-heavy when used, difficult to control, and inconvenient for injection

[0005]The number of animals is generally relatively large. When using the existing syringes, it is impossible to realize drug administration and spray color marking at the same time. It is easy to confuse individual animals who have injected drugs, resulting in repeated injections of the drug

That is to cause the waste of drugs and cause physical harm to animals

Therefore, for a large number of animals, the easy confusion between injected and uninjected animals is a problem that needs to be solved
