Description
Technical field
This utility model relates to the experiment equipment of doctor, pharmaceutical field, particularly relates to a kind of novel rat fixing device.
Background technology
Nowadays rat is one of animal the most often used in zoopery, be usually used in the research in the fields such as nerve-endocrine, behavioristics, nutrition and metabolic disease, surgery, infectious disease, materia medica, hereditism, oncology, current medical research be unable to do without rat, and along with global aging more and more serious, the research that senile rat is carried out also gets more and more.In the experiment carrying out rat, often need the injection carrying out abdominal cavity medicine to rat, as the injection of anesthetics, conventional study medicine.But current abdominal cavity drug injection is to be held by rat with hands or using the carrying out of situation of activity of rat fixing device brute force restriction rat mostly.The abdominal cavity drug injection carried out under the state of these powerful restriction activities in rats, rat can be forced acutely to struggle, strong stress is caused to rat, finally affect experimental result (particularly nerve-endocrine and ethological experiment), and hands is grabbed rat and is often grabbed loosely (particularly senile rat), easily infusion of medicine abdominal cavity important blood vessels or internal organs are caused rats death, research worker is easily bitten by rat.
So carrying out firmly the rat of not anaesthetizing, limiting accurately is the prerequisite of testing it.At present conventional rat fixing device, a part only has and is fixed the trunk of rat, lacks necessary head and fixes, or the space of components of fixing head is comparatively large, and rat head is narrow, when testing, rat head can twist, and hinders the operation of experimenter; Another part fixture, although head, the trunk that can fix rat, instrument is comparatively complicated, and product cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of novel rat fixing device, well cannot fix rat to solve existing apparatus, and instrument is complicated, the problem that cost is higher.
To achieve these goals, this utility model provides following technical scheme: a kind of novel rat fixing device, comprise platen and be arranged on the head locating part on platen, afterbody locating part, described head locating part is provided with the projection for fixing rat tail, projection arranges elastic threads, the end of described elastic threads is connected with one section for being socketed the soft tube of rat tail, described soft tube is fixed on afterbody locating part, described platen is fixedly connected with fixed bar, described fixed bar is also fixedly connected with connecting rod away from one end of afterbody locating part, the two ends of described connecting rod are equipped with screwed hole, described head locating part is provided with the screw rod through screwed hole.
The principle of this programme is such: during use, rat is placed on platen, undertaken spacing and fixing by head locating part and afterbody locating part, projection on head locating part is used for fixing rat tail, bossing arranges elastic threads, the end of elastic threads connects one section for being socketed the soft tube of rat tail, when rat is fixed on after on platen, its tail is fixed through soft tube, be beneficial to fixing rat tail, when rat being put into head locating part and afterbody locating part, according to its bodily form and length, head locating part and afterbody locating part are drawn close to centre, be convenient to afterbody locating part can be encased by head locating part smoothly, when head locating part and afterbody locating part reach appropriate location, only need by screw rod from screwed hole through being fixed, thus head locating part and afterbody locating part are fixed, experimenter is facilitated to operate.This utility model is reasonable in design, structure is simple, and cost is low, fixing firm and solid, to rat noinvasive, and especially convenient batch production; The experimental implementation such as tail venous blood sampling and injection, tail-flick test, tenderness measurement can be carried out easily simultaneously.
Further, the middle part of described platen is provided with the groove of rat ventral health of can fitting, and conveniently carries out spacing and fixing, simple and reasonable for structure to the rat on platen.
Further, the top of described head locating part is connected with anesthetic needle, is anaesthetized rat by anesthetic needle, is convenient to carry out experimental implementation.
Further, described head locating part, afterbody locating part and connecting rod are formed by plastic material, make overall structure light and handy, are convenient for carrying.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel rat fixing device embodiment of this utility model.
