Experimental rat tail-cutting blood collection device

Abstract

The invention discloses an experimental rat tail-cutting blood collection device in the field of experimental apparatuses. The experimental apparatus comprises a front chamber and a rear chamber in sequence. The front chamber and the rear chamber are fixedly connected to each other. The front chamber comprises a trapezoidal plate and a conical plate. Two bevel edges of the trapezoidal plate are fixedly connected to a bottom edge of the conical plate, respectively. The rear chamber comprises a rectangular plate and an arch plate. Two long edges of the rectangular plate are fixedly connected to a bottom edge of the arch plate respectively. A plurality of air vents are circumferentially formed in the conical plate and the arch plate in uniform distribution. One end of the arch plate is hinged to a door sheet matching with the arch plate, and a concentric through hole is formed in the door sheet. A locking groove is formed in the edge of the door sheet, and a connecting buckle fastened to the locking groove is disposed on the rectangular plate. By using the experimental rat tail-cutting blood collection device, as an experimental rat lies in the device, the four limbs of the experimental rat cannot straighten; thus, the experimental rat can be prevented from moving in the front chamber and the rear chamber, fixation of the experimental rat is achieved, and the problem of unsuccessful blood collection caused by the fact that the cut tail enters a plastic bottle due to restless movement of the experimental rat is avoided.

Description

technical field [0001] The invention relates to the field of experimental instruments, in particular to a blood-taking device by docking the tail of an experimental mouse. Background technique [0002] Chinese patent CN200720146836.8 discloses a "fixation device for blood collection by docking the tail of rats", which is made of a plastic bottle. ; The fixed bottle is firmly connected with the fixed plate by the copper wire to form a fixed device. Because the solution uses a plastic bottle as a fixed bottle, since the plastic bottle is cylindrical, it does not conform to the physical characteristics of the experimental rat, causing the experimental rat to stand on the plastic bottle. Pain at the time, restlessness in the plastic bottle, can easily cause the tail of the experimental mouse to enter the plastic bottle, and then cause the failure of blood collection; and there is no air hole on the plastic bottle, because the experimental mouse has been in the plastic bottle fo...
