Abstract
The invention provides a rat hypodermic syringe. The rat hypodermic syringe comprises a syringe body, a fixing plate and an installation plate, wherein the fixing plate and the installation plate are of an integrated structure. The left side and the right side of the fixing plate are respectively provided with a plurality of rat four-limb fixing grooves which are distributed from front to back. The left side and the right side of the upper end face of the fixing plate are provided with a connecting column and a fixing column respectively. The fixing column is provided with an annular elastic binding rope. The upper end of the connecting column is provided with a bent portion extending rightwards. A clamping groove is formed between the bent portion and the connecting column. One end of the elastic binding rope is arranged in the clamping groove in a sleeved mode. Two sliding rails are arranged on the installation plate from left to right and extend frontwards and backwards. The syringe body comprises a needle, a syringe cylinder and a plunger, wherein the needle, the syringe cylinder and the plunger are connected in sequence. A connecting frame is fixed to the periphery of the syringe cylinder. The left end and the right end of the connecting frame both extend downwards to form two reverse-T-shaped sliding blocks respectively, and the sliding blocks are arranged in the sliding rails. According to the rat hypodermic syringe, a rat is effectively fixed through the fixing plate, and therefore one researcher can conduct injection on the rat; in this way, operation is quite convenient. The rat hypodermic syringe is simple in structure and low in cost.
