Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, specifically a sterile isolation device for laboratory animals. Background Technology

[0002] Laboratory animals are animals whose functions, metabolism, structure, and disease characteristics are similar to those of humans when selected as research subjects. The fundamental purpose of medical research is to explore the pathogenesis of human diseases and find prevention and treatment methods. Generally speaking, the higher the evolutionary stage of an animal, the closer its functions, structure, and reactions are to humans. When observing and living laboratory animals, sterile isolation boxes are needed to avoid interference from external bacteria during the breeding or observation of laboratory animals.

[0003] The prior art includes a sterile isolation device for laboratory animals with application number 202322110613.8. This device allows researchers to control the opening and closing of the isolation channel from outside the isolation chamber, making operation simple. In addition, the sterilization chamber is equipped with a first rotating shaft, pulleys, and a belt. Items placed in the sterilization chamber can be conveyed to the side near the isolation chamber via the belt, making it convenient for researchers to move items from the sterilization chamber into the isolation chamber. This solves the problem that researchers may not be able to reach items if they are placed far away in the sterilization chamber. However, the size of the isolation chamber cannot be adjusted, and it is inconvenient for animals to access the items. Utility Model Content

[0004] The purpose of this invention is to provide a sterile isolation device for laboratory animals to solve the problems of existing technologies where the size of the isolation chamber cannot be adjusted and the animals are not easily accessible.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sterile isolation device for laboratory animals, comprising an isolation box, wherein a horizontal sliding block is provided on the top of the isolation box via a threaded screw, and a partition is fixedly provided at the lower end of the horizontal sliding block, and the partition divides the interior of the isolation box into a first isolation chamber and a second isolation chamber, and a cleaning scraper for the box wall is also provided on the outside of the partition, and ultraviolet sterilization lamps are provided on the top walls of the first isolation chamber and the second isolation chamber, and a transparent baffle is provided on one side of the isolation box, and two entrances and exits for the isolation chambers are provided at both ends of the transparent baffle.

[0006] Furthermore, the upper walls of the first and second isolation chambers are provided with air vents, and the upper part of the air vents is provided with filters.

[0007] Furthermore, the lead screw is rotatably mounted in the limiting groove at the top of the isolation box via a bearing, and the two sides of the transverse slider are slidably mounted against the inner wall of the limiting groove.

[0008] Furthermore, one end of the lead screw is provided with an adjustment handle, and a locking bolt is threaded onto the adjustment handle.

[0009] Furthermore, the entrance / exit is externally hinged to a door, and the door and the transparent baffle are fixed together by a pin.

[0010] Furthermore, the cleaning scraper for the box wall includes a side scraper and a bottom scraper disposed on the outer wall of the partition, and both the side scraper and the bottom scraper are triangular rubber plates.

[0011] Furthermore, both the first isolation chamber and the second isolation chamber have slag discharge troughs on one end of their bottom walls, and one end of the slag discharge troughs is open.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a partition to divide the interior of the isolation box into a first isolation chamber and a second isolation chamber for animal isolation and culture experiments. The partition can be adjusted by rotating a screw, thereby adjusting the size of the first and second isolation chambers to meet the needs of animal isolation experiments with different capacities.

[0014] 2. This utility model has two entrances and exits to the isolation chambers at both ends of the transparent baffle. The entrances and exits are connected to the chamber doors by hinges, and the chamber doors and the transparent baffle are connected and fixed by pins. This makes it easier to drive the animals to the side of the entrance and exit when the baffle is adjusted to move laterally by rotating the screw rod and is closer to the entrance and exit, while reducing the animals' activity space and making it easier to take the animals out.

[0015] 3. This utility model also includes a cleaning scraper for the outer wall of the partition. The cleaning scraper includes a side scraper and a bottom scraper set on the outer wall of the partition. Both the side scraper and the bottom scraper are triangular rubber plates. This allows the side scraper and the bottom scraper to be used to scrape off dust and clean the side and bottom walls of the isolation chamber when the partition is adjusted laterally by rotating the screw. The cleaning effect is good and the operation is convenient and quick. Attached Figure Description
