A kidney specimen collection device for animal experiments

Abstract

The invention relates to an animal experiment kidney specimen collecting device. The device comprises a specimen collecting box provided with a specimen collecting mechanism inside; the specimen collecting mechanism is provided with an annular-structured conveying rail; specimen bottles annularly arranged along the conveying rail are placed between an inner stop wall and an outer stop wall; a stationary liquid container and a peristaltic pump are arranged above a working platform; a liquid inlet of the peristaltic pump communicates with the stationary liquid container through a liquid inlet pipe; a liquid outlet pipe connected with a liquid outlet of the peristaltic pump extends above the specimen bottles; a cover buckling mechanism positioned behind the peristaltic pump is arranged on theinner side of the outer stop wall; and a rail driving mechanism is arranged under the working platform. The collecting device can collect and store taken kidneys without needing contact with stationary liquid by experimenters, can guarantee the safety of the experimenters, and is high in efficiency and convenient to use.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a kidney specimen collection device for animal experiments. Background technique [0002] In the field of medicine or biology, researchers often conduct experiments on animals. A considerable part of the experiments require the removal of the kidneys of experimental animals, and the excised kidneys are collected as specimens for inspection. The existing method of collecting kidney specimens for animal experiments is: use tweezers to take out the excised kidney specimens and put them into disposable specimen bags or specimen bottles. The kidney specimens collected by this method have a lot of blood that cannot be drained to affect the detection, and the experimenter needs to touch the specimen fixative once for each specimen collected, and no matter what kind of specimen fixative is harmful to the human body, this undoubtedly increases the experimenter’s burden.

The kidney specimens collected by this method have a lot of blood that cannot be drained to affect the detection, and the experimenter needs to touch the specimen fixative once for each specimen collected, and no matter what kind of specimen fixative is harmful to the human body, this undoubtedly increases the experimenter’s burden. Security risks

[0003] Existing specimen collection devices are not suitable for resected kidneys of experimental animals. For example, the invention patent with application number 201510641366.1 provides a surgical organ and lymph node specimen preservation and recording method and a classification collection box, including a notch with the same shape as the organ. Staging box Ⅰ for organ specimen storage tank and staging box Ⅱ with lymph node specimen storage tank and anatomical atlas of sampled organs. This collection box only stores organ specimen staging box without specimen draining and fixative processing mechanism, which needs to be done manually by the experimenter. It is not suitable for long-term preservation of organ specimens; another example is the case specimen collector provided by the invention patent with application number 201710032244.1, including a solution bottle, which is connected to the bottom of the specimen separator through an infusion tube, and the specimen separator is separated The upper and lower chambers are connected through the drip head. The upper chamber of the sample separator is equipped with a medical filter. The upper end of the sample separator is connected with the drainage tube, and the solution bottle is connected with the buffer bottle through the connecting tube. , the buffer bottle is connected with the negative pressure guide tube, the collector is only suitable for collecting small tissue fragments, and cannot be used to collect the kidneys of experimental animals
