Cage valve device

Abstract

The present invention provides a cage valve device for enabling regulation of air by inducing the same to be smoothly suctioned into or discharged from a cage, which is an experimental animal rearingdevice. The cage valve device of the present invention is mounted in an animal-rearing cage having a suction hole and a discharge hole and comprises: a cylindrical valve member of which one end is blocked and a side surface is opened, and which has a first serrated protrusion formed along a one-sided outer periphery thereof; a mesh-type filter member inserted into the valve member in a shape corresponding to the inside of the valve member; a hollow nozzle part communicating with the filter member and having a second protrusion formed on the front end thereof; and a fastening member, which is made of an elastic material, for coupling or fixing the first protrusion and the second protrusion, wherein the filter member can be separated from the nozzle part and replaced, and is mounted in the suction hole so as to supply air from the outside to the inside of the cage or is mounted in the discharge hole so as to induce air inside the cage to be discharged to the outside.

Description

technical field [0001] The present invention relates to a valve device for a cage, and more particularly, to a valve device for a cage intermittently controlled by smoothly sucking or discharging air into the cage as a laboratory animal breeding device. Background technique [0002] The husbandry of laboratory animals has become critical for active biotechnology research such as clinical trials, disease models, and breeding. Recently, in order to raise a large number of experimental animals, studies on breeding spaces have been actively conducted. In particular, individual ventilated rearing devices for contamination prevention and aseptic rearing have been developed. [0003] Individually ventilated breeding facilities (often referred to as breeding buildings) have attracted attention as efficient breeding facilities by keeping large numbers of animals in a small space. [0004] Such as figure 1 Cage air was kept constant by forcibly supplying and exhausting filtered ste...

AI Technical Summary

Problems solved by technology

[0006] The advantage of this existing valve device is that there is no interference after slender parts and assembly, but there are problems such as complex construction, large number of parts required, and limitations of self-sealing

[0007] In addition, the existing valve device radiates through a very small hole, and the flow of air is unnatural to generate noise, and there is a problem in ventilation performance because there is a large amount of air resistance structure
