Technical Field

the invention relates to the technical field of experimental equipment, in particular to an animal experiment urine collecting device.

Background

When animals are tested in medical or other fields, the urine without pollution needs to be collected regularly for detection and analysis. The animal urine collection method includes metabolism cage method, catheterization method, bladder compression method, ureter intubation method, bladder puncture method, laparotomy method and reflex urination method.

The metabolic cage method is to place the animal in a specially-made cage, when the animal defecates, the urine and the excrement can be separated through a urine and excrement separating funnel at the bottom of the cage, so that the purpose of collecting the urine is achieved, however, the urine collected by the method is polluted, and the detection data error is large. The catheterization method is to fix the animal on an operating table after mild anesthesia, insert a catheter through the urethra and collect uncontaminated urine, but the method cannot collect urine regularly under the condition that the animal is relatively free at present, and only the animal can be fixed on the operating table to collect urine. The bladder compression method is to slightly anaesthetize the animal, and then the experimenter presses the lower abdomen of the animal with hands which are soft and forceful, when the pressure is enough to relax the bladder sphincter of the animal, urine is automatically discharged from the urethra, but the method is difficult to control according to the pressure degree, so that the urine is difficult to discharge, and the method is only suitable for large animals. Ureter intubation, bladder puncture, laparotomy, etc. are invasive acquisitions, too intolerable for animals, and not suitable for continuous, timed acquisition of urine. The reflection urination method is suitable for mice, and the defecation reflection is obvious when the mice are held by a tail of a person and lifted, so that the mice can be lifted when a small amount of urine needs to be taken, and the discharged urine is received in a container with scales.

Therefore, the catheterization method is the most suitable method for collecting the completely pollution-free urine at regular time. The technical personnel in the field need to solve the problem how to regularly collect the completely pollution-free urine by adopting the catheterization method under the condition of ensuring the relative freedom of animals.

2. The invention does not need to keep the experimental animal in an anesthesia state all the time or fix the experimental animal on the operating table all the time, and only needs to keep in captivity, thereby ensuring certain freedom of the experimental animal and avoiding the condition of larger error of urine detection data.
