Description

Animal fixer for abdominal cavity injection

Technical Field

The utility model relates to the technical field of experimental animal fixing equipment, in particular to an animal fixer for abdominal cavity injection.

Background

Intraperitoneal injection is one of the most common systemic administration modes in animal experiments. In the process of intraperitoneal injection administration operation, a rat is generally fixedly grabbed by a left hand when operated by a single person, the head of the rat is downward, so that abdominal organs move to the far end to avoid being damaged by a needle head, and the disposable injector is held by the right hand to perform intraperitoneal injection; when operated by two persons, one person usually fixes the animal and the other person carries out intraperitoneal injection. At present, the types of animal fixing facilities on the market are few, no animal fixing equipment specially designed for intraperitoneal injection operation exists, and experimenters often fix animals by using self-made simple materials. When the device is operated by a single person, the position of limbs is not easy to fix, the swing of the hind limbs and the tail of an animal often influences the operation, so that the needle insertion is difficult, the experimental operation time is obviously prolonged, and the risk of damage to abdominal viscera and peripheral tissues is increased; the waste of labor cost is increased when the double-person operation is carried out. In the prior art, an animal fixer is often required to be arranged at a certain fixed position of a laboratory bench, so that inconvenience is brought to an operator; because the apparatus is formed by extending or improving glass or polyethylene pipes, the volume and the shape can not be adjusted, so the apparatus can adapt to narrow animal body size range and can not effectively fit larger or smaller animal body sizes.

The animal fixer that current glass or polyethylene made, its inner wall is smooth, may appear two kinds of situations when fixed animal: 1. the fixation is not enough, the mobility of animals is too large, sliding and displacement are easy to occur, and the intraperitoneal injection is not facilitated; 2. too tight fixation and poor comfort for the animal. Furthermore, after the animal is confined in the existing fixture, the abdomen is not effectively exposed except for the tail and the hind paw, which causes great difficulty in the operation of the intraperitoneal injection. The act of directly catching the animal by hand during the experiment also presents a risk of being bitten by the animal.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to overcome the above difficulties and provide an animal fixer for abdominal cavity injection.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an animal fixer for intraperitoneal injection, includes first arc fixer pterygoid lamina and second arc fixer pterygoid lamina, first arc fixer pterygoid lamina and second arc fixer pterygoid lamina pass through the joint articulated, first arc fixer pterygoid lamina and second arc fixer pterygoid lamina all include pterygoid lamina somatic part and pterygoid lamina head, the clip is connected to pterygoid lamina somatic part top, the clip is including the hinge, the hinge top is connected with the handle, hinge bottom central authorities fixedly connected with dead lever, dead lever bottom fixedly connected with self-adhesive tape.

As an improvement, the inner sides of the first arc-shaped fixer wing plate and the second arc-shaped fixer wing plate are fixedly connected with a patterned latex lining.

As an improvement, a first adjusting screw and a second adjusting screw are arranged on the first arc-shaped fixer wing plate and the second arc-shaped fixer wing plate.

As an improvement, the top ends of the first arc-shaped fixer wing plate and the second arc-shaped fixer wing plate are connected with a hook.

As an improvement, the hinge is connected with the wing plate body through a screw.

Compared with the prior art, the utility model the advantage lie in: the arc-shaped fixer wing plate of the utility model can adapt to wider animal body type range; the design of the patterned latex lining, the fixing rod and the adjusting screw can fix animals more accurately and compactly; the wide space on the ventral side is beneficial to more conveniently carrying out the intraperitoneal injection, the utility model can be operated by one person, the labor cost is saved, and the time cost of the experimental operation is reduced; the operation process is simplified, and meanwhile, the risk of being bitten by animals is also avoided.

As shown in the figure: 1. a first arcuate retainer wing; 2. a second arcuate retainer wing; 3. a wing plate body; 4. a patterned latex lining; 5. a fixing rod; 6. self-adhesive tape; 7. a clip; 8. a hinge; 9. a handle; 10. a screw; 11. a wing plate head; 12. a joint; 13. a first adjusting screw; 14. a second adjusting screw; 15. and (4) hanging hooks.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Combine the attached drawing, an animal fixer for intraperitoneal injection, including first arc fixer pterygoid lamina 1 and second arc fixer pterygoid lamina 2, the arc fixer pterygoid lamina is two symmetries, the glossy arc structure in edge, first arc fixer pterygoid lamina 1 and second arc fixer pterygoid lamina 2 are articulated through joint 12, first arc fixer pterygoid lamina 1 and second arc fixer pterygoid lamina 2 all include pterygoid lamina somatic part 3 and pterygoid lamina head 11, are equipped with the partition between the two, are convenient for fixed animal, clip 7 is connected to pterygoid lamina somatic part 3 top, clip 7 is including hinge 8, hinge 8 top is connected with
