A device for intraperitoneal injection and tail vein blood collection

Abstract

The invention discloses an intraperitoneal injection and caudal vein blood sampling device, which comprises a porous plastic board, a supporting device, auxiliary fixing devices and a cloth bag. The auxiliary fixing devices are respectively arranged on the lateral surfaces of both ends of the porous plastic board, and each auxiliary fixing device comprises a fixed rod and a telescopic rod; a head fixing clamp is arranged at the left end of the upper part of the porous plastic board, and a neck fixing pile is arranged at the right end of the head fixing clamp; a drug feeding hole is formed in the middle part of the porous plastic board, and a tail blood sampling fixing device is arranged at the upper end of a tail blood sampling hole; a tail fixed hole is formed in the right side of the tail blood sampling hole; moreover, a bulge is formed at the lower part of the supporting device; the upper part of the supporting device is hinged with one end of a connecting piece by a rotating shaft, and a clamping ring corresponding to the bulge is arranged at the other end of the connecting piece; the lower end of the supporting device is hinged with a rotary table by a rotating shaft; and a base is arranged at the lower end of the rotary table. The intraperitoneal injection and caudal vein blood sampling device is convenient to sample blood, has high working efficiency, is convenient to use, and has high practicality.

Description

technical field [0001] The invention relates to the technical field of devices for intraperitoneal injection and tail vein blood collection, in particular to a device for intraperitoneal injection and tail vein blood collection. Background technique [0002] At present, when the existing rats are injected intraperitoneally, there is no good fixer, and the fixation effect of the existing rat fixer is not ideal, and it cannot be fixed for all mice, has certain limitations, and the safety performance is not high, and The fixation is not firm, and the intraperitoneal injection cannot be performed smoothly and safely. At the same time, the structure of the fixer is relatively simple, with few functions, and the blood collection operation cannot be performed at the same time. Many experiments cannot be performed independently by one person, which wastes manpower and low experimental efficiency, which affects the experimental research. In order to facilitate and effective Perform i...

[0002] At present, when the existing rats are injected intraperitoneally, there is no good fixer, and the fixation effect of the existing rat fixer is not ideal, and it cannot be fixed for all mice, has certain limitations, and the safety performance is not high, and The fixation is not firm, and the intraperitoneal injection cannot be performed smoothly and safely. At the same time, the structure of the fixer is relatively simple, with few functions, and the blood collection operation cannot be performed at the same time. Many experiments cannot be performed independently by one person, which wastes manpower and low experimental efficiency, which affects the experimental research. In order to facilitate and effective Perform intraperitoneal injection of mice and simultaneously carry out tail blood collection operation, the present invention proposes a device for intraperitoneal injection and tail vein blood collection
