Embodiment 1

[0024] The present invention provides such as Figure 1-5 A biochemical product injector for rodent experiments is shown, which includes an arc-shaped fixing plate 1, and a notch 2 is provided through the bottom middle of both sides of the arc-shaped fixing plate 1, and the arc at the top of the notch 2 is Both sides of the shaped fixing plate 1 are provided with a first chute 3, and the bottom of the notch 2 on each side is respectively provided with a first slider 4, and the bottom end of the first slider 4 is provided with a fixing hole 5. The central position of the top of the arc-shaped fixed plate 1 is provided with a through groove 6, and the middle part of the inner wall on both sides of the through groove 6 is provided with a second chute 7, and the inside of the through groove 6 is provided with a second slide block 8, and the second sliding block 8 is arranged inside the through groove 6. Both ends of the slider 8 are provided with a first through hole 9 on one side...

Embodiment 2

[0032] Different from Embodiment 1, a plurality of vacuum suction cups 26 are evenly distributed on the bottom edge of the arc-shaped fixed plate 1, and a micro-vacuum pump 25 is fixed on the surface of the arc-shaped fixed plate 1, and the micro-vacuum pump 25 is connected with the vacuum suction cups. 26 is provided with a connecting hose 27, and the two are connected through the connecting hose 27, which is conducive to placing the rodent on the bottom of the arc-shaped fixing plate 1, and using the fixing hole 5 on the first slider 4 Fix its limbs, and at the same time, after using the inflated air bag 21 to fix its trunk, the gas in the cavity formed between the vacuum chuck 26 and the test table is drawn out by the micro-vacuum pump 25, so that a cavity is formed inside the cavity. Negative pressure space, so that the arc-shaped fixing plate 1 is firmly adsorbed on the test bench, which can prevent the operator from pressing the arc-shaped fixing plate 1 by hand, thereby ...

Abstract

The invention discloses a biochemical product syringe used for rodent experiments, and specifically relates to the technical field of medical instruments. The biochemical product syringe used for therodent experiments comprises an arcuate fixing plate; notches are arranged at middle parts of the bottom on two sides of the arcuate fixing plate in a penetrating way; first chutes are arranged, on two sides of the arcuate fixing plate, at the tops of the notches; first sliders are arranged at the bottoms of the notches; fixing holes are arranged at the bottom ends of the first sliders in a penetrating way; a through groove is arranged at a central position of the top of the arcuate fixing plate; and second chutes are arranged at middle parts of the inner walls on two sides of the through groove. According to the biochemical product syringe used for the rodent experiments, four limbs of rodents of various sizes can be fixed by utilizing the first sliders on the arcuate fixing plate. The trunk part of an experimental rodent can be fixed by utilizing an inflated airbag; sleeves are twisted so as to adjust distances between the top end of the sleeves and the bottom end of a second slider;and sleeve rings are twisted so as to adjust relative height of the sleeve rings on the syringe, thereby realizing adjustment on needle insertion depth.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, the invention relates to a biochemical product injector used for rodent experiments. Background technique [0002] Animal medical syringes are often used in animal medical experiments. When injecting animals in the experiment, the animals usually move around. The experimenter has to hold the syringe while injecting, which is very inconvenient, and it usually takes a lot of money to draw the drug. Greater strength. [0003] The utility model patent of the patent application publication number CN 205924238 U discloses an animal syringe. When the experimental animal is quiet, the animal syringe is directly thrown at the experimental animal. The injection needle is inserted into the muscle tissue of the animal, and the hand-held air bag is compressed. When the hose enters the air cavity, the pressure in the air cavity increases, pushing the piston to move to the left, ...
