Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an automatic water supply device for laboratory animals, in which each component is a detachable separate structure, and each component can be disassembled and cleaned or sterilized as necessary. The present invention relates to a water contact amount measuring device.

In general, large numbers of experimental animals are kept for the purpose of confirming the safety of pharmaceuticals, agricultural products, food additives, etc. when developing them, or testing their medicinal efficacy.

A flow meter (v
When the animal is small, a microflow meter (described later) is used.

By the way, in order to prevent bacteria from entering the water to be supplied, an automatic water supply system consisting of a water tank, a flow meter, a water supply pipe, etc. must be constructed so that it can be sufficiently cleaned and sterilized as necessary. An object of the present invention is to provide an automatic water supply device with a structure in which each component can be disassembled and detached in order to meet this requirement.

Another object of the present invention is to provide a water supply amount measuring device that allows the approximate amount of water intake to be determined by precisely measuring the amount of water intake using a microflow meter and visually observing the liquid level in a water storage tank. It is in.

The configuration of the present invention will be explained below based on one embodiment shown in the drawings.

In FIG. 1, 1 is a breeding pond in which experimental animals are housed. Reference numeral 2 denotes a cylindrical body held by a support 3 and vertically attached to the outer wall of the breeding n1, and the material thereof is preferably made of heat-resistant glass.

A bottom part 4 made of an elastic material such as heat-resistant rubber is fitted into the lower part of the cylindrical body 2, and a lid 5 made of an elastic material such as heat-resistant rubber is fitted into the upper part. Reference numeral 6 designates an outflow port formed approximately in the center of the bottom portion 4, and reference numeral 7 represents a flow port formed in the lid 5. Reference numeral 8 denotes a water tank, which is composed of the above-mentioned cylindrical body 2, bottom portion 4, and lid 5. 14 is a flow meter, for example, the present applicant filed a patent application in 1973.
8-149039 uses a microflow measuring device that has already been cast.

In other words, as shown in FIG.
and an outflow pipe section 12 that flows out as a continuous flow or a droplet flow equivalent to a droplet flow are integrally configured in a measurement container 13. In addition, in the embodiment shown in FIG. 2, the detection unit 11 detects the number or passing speed of droplets based on the presence or absence of droplets between the electrodes, but it can of course also be detected by light or other physical quantity detection means. good. Reference numeral 16 indicates the water supply amount W, which is connected to the outflow pipe 15 of the flow meter 14 through a connecting member 17 having a communication port 18.

Here, the connecting member 17 is preferably made of an elastic material such as heat-resistant rubber. Further, it is desirable that the water supply pipe 16 be held substantially horizontally and that its tip be attached to a lower part of the cage 1 at a position where the experimental animal can drink easily.

Reference numeral 119 is an automatic water supply valve, and preferably has a structure that opens when a small animal or the like lightly touches the tip with its mouth. 20
is a calculation display section into which the signal from the detection section 11 transmitted via the connector 21 is input, and has a built-in signal converter, amplifier, arithmetic unit, storage section, display section, etc. be.

According to the present invention having the above structure, the cylindrical body 2, lid 5, and bottom 4 that make up the water storage tank 8 can be easily disassembled, so when these are separated, there is no part where water can accumulate inside. . Further, since the flow meter 14 is integrally constructed and buried, and each component can be disassembled individually if necessary, there is no stagnation part inside.

The connecting member 17, water supply pipe 16, automatic water supply valve 19, etc. can also be removed. Furthermore, the detection unit 11
However, since it can be disassembled at the connector 21, it can be separated from the calculation display section 20. As described above, all the parts constituting the water contact amount measuring device of the present invention are easy to attach and detach and have a simple structure, so sterilization or cleaning using high temperature steam etc. in an autoclave etc. can be accomplished very easily and completely. be able to. Furthermore, since the side wall of the water tank is made of a visible transparent material, it is extremely useful for checking the water level and managing the animals.
