Abstract
The utility model belongs to the field of experimental instruments, and provides an adjustable rat tail intravenous injection fixer, which is characterized in that: the fixer comprises two clamping pieces connected through a torsion spring rotating shaft, each clamping piece comprises an operation part and a clamping part, two ends of the connecting rotating shaft of each clamping piece are respectively provided with a baffle matched with the clamping parts, and a plurality of groups of long grooves are formed in one end of each clamping part along the length direction. The device clamps the test mouse to limit the test mouse so that the test mouse is motionless, and the tail of the test mouse penetrates out of the long groove to be exposed out of the device, so that intravenous injection of the test mouse is facilitated; the space in the clamping part can be adjusted through the operation part so as to adapt to rats with different sizes for intravenous injection, and the problem that the existing fixer is complex in structure, troublesome in operation, incapable of adjusting the size of the fixer and further incapable of accurately fixing rats with different sizes is solved.
Description
Technical Field
The utility model belongs to the field of experimental instruments, and particularly relates to an adjustable rat tail intravenous injection fixer.
Background
Rats, as a commonly used laboratory animal, are of paramount importance in biomedical research. The rat tail vein has the advantages of easy searching, strong visibility, quick absorption, definite dosage and the like, becomes the common operation skill in the pharmacological and toxicological experiments of rats, and has important influence on the experimental results if the rat tail vein is smooth or not.
In the actual operation process, the existing injection fixer has complex structure and troublesome operation, and is usually operated by multiple persons, and the specification and the size of the rats are sometimes error, so that the fixer can not accurately fix the rats with different sizes.
Disclosure of Invention
In view of the above problems, the present utility model aims to provide an adjustable rat tail intravenous injection fixator, which aims to solve the problems that the existing fixator is complex in structure and troublesome in operation, the size of the fixator cannot be adjusted, and rats with different sizes cannot be accurately fixed.
The utility model adopts the following technical scheme: an adjustable rat tail intravenous injection fixer, characterized in that: the fixer comprises two clamping pieces connected through a torsion spring rotating shaft, each clamping piece comprises an operation part and a clamping part, two ends of the connecting rotating shaft of each clamping piece are respectively provided with a baffle matched with the clamping parts, and a plurality of groups of long grooves are formed in one end of each clamping part along the length direction.
Further, at least one group of ventilation holes are formed in the clamping part, and the ventilation holes are located at the other end of the clamping part.
Further, the baffle is provided with air dispersing holes.
The beneficial effects of the utility model are as follows: when the rat tail intravenous injection is carried out in a laboratory, the device clamps the test rat to limit the rat tail so that the rat tail is motionless, and the rat tail penetrates out of the long groove to be exposed outside the device, so that the intravenous injection of the test rat is convenient; the space in the clamping part can be adjusted through the operation part so as to adapt to rats with different sizes for intravenous injection; in addition, the device has simple structure and is easy to operate by a single person.
Drawings
Fig. 1 is a schematic view of an adjustable rat tail intravenous injection fixator according to the present utility model.
Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.
Only those parts relevant to the embodiments of the present utility model are shown for convenience of description.
Referring to fig. 1, the fixing device comprises two clamping pieces connected through a torsion spring 1, each clamping piece comprises an operation part 2 and a clamping part 3, two ends of a connecting rotating shaft of each clamping piece are respectively provided with a baffle 4 matched with the clamping part 3, and a plurality of groups of long grooves 5 are formed in one end of the clamping part 3 along the length direction.
When the rat tail intravenous injection is carried out in a laboratory, the device clamps the test rat to limit the rat tail so that the rat tail is motionless, and the rat tail penetrates out of the long groove to be exposed outside the device, so that the intravenous injection of the test rat is conveniently carried out.
Specifically, the present utility model relates to a method for manufacturing a semiconductor device. Two clamping pieces are opened by operating the operating part, rats are placed in the clamping part, and the size of the space in the clamping part is adjusted by operating the operating part, so that the device is suitable for test rats with different specifications and sizes. When the rat is fixed, the rat tail is penetrated out of the long groove, so that intravenous injection is conveniently carried out on the rat tail. The baffle is mainly used for preventing the rat from escaping in the clamped and fixed process. In addition, the device has simple structure and is easy to operate by a single person. Notably, are: the torsion spring has relatively small elasticity and does not cause damage to rats.
As a preferable structure, the clamping part 3 is provided with at least one group of ventilation holes 6, and the ventilation holes 6 are positioned at the other end of the clamping part 3. The baffle plate is provided with air dispersing holes 7. The ventilation holes and the air dispersing holes are mainly used for facilitating the breathing of the rats, and when the rats are clamped, the rat tail penetrates out of the long groove 5 to be placed, and the ventilation holes are formed in the corresponding ends of the long groove, so that the rats can breathe more conveniently.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
