Embodiment 1

[0021] Such as figure 1 As shown, the rat holder includes a head holder 1, a tail holder 2 connected to the bottom of the head holder 1, and an anesthesia member 3 connected to the top of the head holder 1; the tail holder 2 The top end is provided with more than two slits, the cross-section of the head fixing part 1 gradually expands from the top to the bottom, and the cross-section of the tail fixing part 2 gradually decreases from the top to the bottom; Both the part 1 and the tail fixing part 2 are cavity structures, and the top and bottom ends of the head fixing part 1 and the tail fixing part 2 are both open structures. Described head fixture and tail fixture are designed according to the body shape of rat completely, and its head and tail are narrower, and middle part is wider, so fixture and tail fixture are designed as above-mentioned structure. Of course, the head fixture and the tail fixture can also be designed as a semi-ellipsoid structure, but the two ends are i...

Abstract

The invention discloses a rat fixator which solves the problems that the conventional device cannot fix a rat well, an instrument is complex and the cost is high. The rat fixator comprises a head fixing piece, a tail fixing piece and an anesthesia piece, wherein the tail fixing piece is connected with the bottom end of the head fixing piece; the anesthesia piece is connected with the top end of the head fixing piece; the end part of the top end of the tail fixing piece is provided with more than two cracks; the cross section of the head fixing piece is gradually enlarged from the top end to the bottom end; the cross section of the tail fixing piece is gradually shrunk from the top end to the bottom end; the head fixing piece and the tail fixing piece are of cavity structures; and the top ends and the tail ends of the head fixing piece and the tail fixing piece are of opening structures. The rat fixator is reasonable in design, simple in structure and firm in fixation, does not injure the rat and particularly facilitates batch production; and the rat fixator can conveniently perform test operation such as caudal vein blood collection, injection, tail flick test, pressing pain measurement and the like.

Description

technical field [0001] The invention belongs to experimental equipment in the field of medicine and pharmacy, in particular to a rat fixator. Background technique [0002] Rats are one of the most commonly used experimental animals in medicine. Firm and accurate restraint of unanesthetized rats is the prerequisite for experiments on them. Currently commonly used rat fixation devices, part of which only fixes the trunk of the rat, lacks the necessary head fixation, or the parts for fixing the head have a large space, and the rat head is narrow and small. During the experiment, the rat The head will twist, hindering the operation of the experimenter; although the other part of the fixing device can fix the head and torso of the rat, the instrument is more complicated and the product cost is higher. Contents of the invention [0003] The object of the present invention is to provide a rat immobilizer, which solves the problems that the existing device cannot fix the rat wel...
