Rat caudal vein blood sampling device

Abstract

The invention discloses a rat caudal vein blood sampling device, which is characterized by comprising a bottom plate, a connecting rotating shaft, a cover body, an operation table, a storage drawer, amouse locking cage, a mouse locking cage rotating shaft, a rotating shaft base, a tail fixing table, a supporting connecting column, a guide rail, a centrifugal machine body, a centrifugal machine cover, a blood drawing tube, a vacuum blood vessel bottle and a constant-temperature water bath tube. According to the device, a rat fixing device, a tail fixing device, a heating device, a blood sampling device and a centrifugal machine are integrated, all steps are seamlessly connected when the device is used, and the efficiency is higher; and the rat caudal blood vessel filling adopts dual effects of electric heating and compression, so that the effect is more obvious.

Description

technical field [0001] The invention belongs to the field of rat experiments, and relates to a rat tail vein blood collection device. Background technique [0002] Rat experiments are of great significance in medical research or animal research. Blood collection and drug administration through the tail vein of rats are more commonly used experimental methods. Rats are relatively active animals. When collecting blood, the rat needs to be fixed, and its tail is fixed to collect blood from its tail vein; however, the current rat fixing device cannot fix the rat in a posture suitable for blood collection. Or the design structure of the existing fixing device is defective, and the rat is fixed in it unstablely, and there is a danger of breaking free, which causes a lot of inconvenience to the experimental process; the rat tail vein blood collection device currently used needs to fix the rat with a fixing device first , and then transfer to a special blood collection device for b...

Rats are relatively active animals. When collecting blood, the rat needs to be fixed, and its tail is fixed to collect blood from its tail vein; however, the current rat fixing device cannot fix the rat in a posture suitable for blood collection. Or the design structure of the existing fixing device is defective, and the rat is fixed in it unstablely, and there is a danger of breaking free, which causes a lot of inconvenience to the experimental process; the rat tail vein blood collection device currently used needs to fix the rat with a fixing device first , and then transfer to a special blood collection device for blood collection, and then transfer the blood to the centrifuge after the blood collection, the steps are more troublesome; and at present, manual blood collection is performed with a syringe, because the tail vein of the rat is small, manual blood collection will lead to bleeding During the process, the syringe could not be grasped stably, and the needle would deviate in the tail; the tail vein of the rat is relatively small, and it is difficult to find it accurately under normal circumstances. Therefore, before blood collection, the rat tail blood vessel should be filled. Heating, this method needs to soak the tail of the rat in hot water, which is very inconvenient after the rat is fixed; 2, the rubber band oppresses the tail, the tail of the rat is thinner and the skin is harder, this method is inefficient, poor effect
