Description

Foldable big mouse metabolism cage with cold-stored function

Technical Field

The invention relates to the technical field of experimental equipment, in particular to a folding type rat and mouse metabolism cage with a refrigeration function.

Background

The genetic and biological backgrounds (including the normal range of various data such as anatomy, physiology, clinical pathology and the like) of the rats and the mice are clear, and the cost is low, so the method is widely used for the research in the fields of clinical toxicology and the like, so that the research on how a tested object (such as a chemical such as a drug) acts on an organism in vivo and how the organism treats the tested object to convert in vivo is needed, the research on the metabolic products of experimental animals is very important for the understanding of the metabolic process of the tested object in vivo, and the collection of the feces and urine of the rats and the mice is one of the important ways at present.

The existing metabolism cage for big and small mice mainly comprises three parts, namely a cage, a feces and urine separation device and a collection container from top to bottom, wherein the cage is a fixed space for holding the big mice; the excrement and urine separating device is in a funnel-shaped form, a non-fixed screen plate is horizontally placed at the wide opening of the funnel to separate excrement from urine, the excrement is isolated on the screen surface, and the urine flows into the collecting container along the funnel mouth.

Under the present condition, metabolism equipment uses not every day, and the squirrel cage that metabolism cage utensil used need to guarantee certain cage space for complying with GB14925-2010, also needs the supporting shelf of placing the metabolism cage simultaneously, because of it all can not light dismantle the reduction volume, big mouse experiment one-time use quantity is as many as hundred simultaneously single collections simultaneously, including experimental animals raises the regional and the regional daily high-volume operation maintenance of supporting, deposit when usual idle and occupy a large amount of experimental animals facility space in a certain degree, cause unnecessary economic loss. Secondly, although the excrement and urine separation device can separate excrement and urine at present, most separation nets and collection funnels are not tight, and deformation in the using process still can appear mixing excrement and urine in the urine collection device, and urine routine detection is abnormal to a certain extent. On a collection container, a single common collection bottle is mostly adopted in the current sample collection container, refrigeration and preservation measures are basically not adopted, excrement and urine are exposed in a room temperature environment, and if the sample is collected overnight or for a long time, metabolic active products with unstable characters can be influenced to a certain extent.

Therefore, a foldable rat metabolism cage with a refrigeration function is needed, a foldable and telescopic cage body and a foldable and telescopic cage frame are realized, and the storage volume is compressed; the urine is prevented from mixing with the excrement; ensure that the metabolic sample is in a refrigerated state and delay the deterioration of unstable metabolites. When the device is not used, the matched objects are piled up and placed, and the space is saved.
