Detailed Description
The fixing device for intraperitoneal injection of rats according to the present utility model will be further described with reference to the accompanying drawings.
The fixing device for the intraperitoneal injection of the rats shown in fig. 1-2 comprises a fixing sleeve 1 and a fixing clamp 3 matched with the fixing sleeve to be clamped on the fixing sleeve 1, clamping bands 2 are arranged on two side walls of the fixing sleeve 1, and the fixing clamp 3 is clamped on the fixing sleeve 1 through the clamping bands 2 and slides in the length range of the clamping bands 2. The fixing sleeve is used for fixing the head and the back of the rat, and the fixing clamp 3 is used for fixing the armpit of the rat.
As shown in fig. 3 to 5, the fixing sleeve 1 comprises a head sleeve 11 for fixing the head of a rat and a back sleeve 12 for fixing the back of the rat, and the head sleeve 11 and the back sleeve 12 are integrally formed. The head sleeve 11 is of an open funnel-shaped structure, so that the rat head can be conveniently fixed; the back cover 12 has a U-shaped structure, and the heights of the two side walls of the U-shape gradually become smaller along with the distance from the head cover 11 so as to facilitate the entry and lying of rats. The clamping bands 2 are symmetrically and fixedly arranged on two sides of the fixing sleeve 1 through screw parts, one end of each clamping band is fixed on the head sleeve 11, and the other end of each clamping band is fixed on the back sleeve 12. The fixed sleeve 1 and the clamping band 2 are preferably made of plastic materials, and the fixed sleeve 1 is matched with the clamping band 2 to be provided with an annular groove 13, so that the space of the fixed clamp 3 is enlarged, and the fixed clamp 3 can slide in the clamping band 2 conveniently.
The fixing clip 3 comprises a grip handle 31 for gripping and a clamping jaw 32 for clamping the fixing sleeve 1, the grip handle 31 and the clamping jaw 32 being hingedly engaged by a spring 33. Both the clamping jaw 32 and the clamping holder 31 are made of polypropylene. The stress points of the rats are large and uniform, and clamping blocks 34 with the width larger than that of the clamping jaws 32 are arranged at the top of the clamping jaws 32 far away from the clamping handles 31, so that the contact surface of the fixing clamp 3 with the rats when the rats are clamped is enlarged; the spring 33 has moderate elasticity and prevents over-loosening or over-tightening; the grip 31 is about 6 cm long.
The specific operation steps of the device are as follows:
step one, grabbing rats: the rat tail is grabbed from the rat cage, the rat is placed on the experiment table, the left hand grabs the rat tail and pulls the rat tail to the human body part, the rat can be pulled forward, the right hand-held rat body is placed in the clamping handle 31 of the fixing device, the direction is downward, the head of the rat is driven to drill into the funnel-shaped headgear 11 by combining the natural habit of the rat with the boring preference, and the clamping handle 31 of the hand-held fixing clamp 3 slides to one side of the rat body along the clamping belt 2 to clamp the armpit part of the rat.
Step two, fixing the rat: the right hand reversely supports the clamp holder 31 to enable the abdomen of the rat to face upwards, the head of the rat faces obliquely downwards, the tail of the rat faces obliquely upwards by virtue of the head cover 11 and the clamp holder 31 to form an A-frame, and the effect is to enable the viscera of the rat to deviate towards the head due to the action of gravity, so that the needle head is prevented from being pricked into the viscera during intraperitoneal injection.
