Description

TECHNICAL FIELD The present invention relates to a method for measuring the weight of an animal in a cage and an apparatus therefor.

[Conventional technology and its problems]

Conventionally, in measuring the weight of an animal in a cage, each animal was taken out of the cage and measured with a platform scale.

Therefore, some kinds of electronic scales can quickly read the static weight of a moving animal, but it takes a lot of time and labor to put the animal in and out, which is a problem.

In addition, there is a device for incorporating and measuring an automatic weight measuring device in each cage, but it is very expensive and cannot be used in a laboratory or a hospital that handles many experimental animals.

Therefore, the present invention intends to provide a method and an apparatus thereof capable of performing weight measurement extremely labor-saving and efficient.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a detachable type (insertion type) of a weighing instrument, which can be raised and lowered without fixing an animal receiving floor plate or a treadle (slat) in a cage, and the weighing instrument is provided with Provide a lifting guide to lift the floor plate or tread,
The weight can be measured without moving the animal in and out.

Hereinafter, a method for measuring a weight of an animal in a cage and a device therefor according to the present invention will be described with reference to the accompanying drawings.

〔Example〕

FIG. 1 shows an overall view of the embodiment, in which 1 is a cage for 3 animals, 2 is a platform scale plate-like scale, and 3 is a display device.

Unlike the conventional cages, each cage does not have a floor. As shown in FIGS. 3 and 4, there are meter receiving parts 11, 11 inclined inward on both sides of the lower part, and both sides are on the upper part. It has a structure in which treads (slats) 12 in which 12a and 12a are bent in a c-shape are placed.

The weighing device 2 is a plate-shaped platform weighing device as shown in FIG. 2 designed for the embodiment, in which a handle 22 provided with a switch 21 is provided on the front side, and a load cell is provided between the substrate A and the upper plate B. C is sandwiched, and sled-shaped lifting guides 23, 23 for lifting the tread 12 are provided on both sides of the upper plate B.
Positioning guides 24, 24 are provided on both sides of the lower surface of the.

Reference numeral 25 is a cord for connecting the display device 3 and the load cell C, and the display device 3 has the following functions.

1) .The function to erase the tare such as the tread 12, 2) .The function to quickly reduce the weight of the animal which is not standing by the program processing of the detected value, 3) .The digital display of the measured value and the output to the computer etc. The function to be performed and the usage thereof will be described. When measuring the weight, the weighing instrument 2 is inserted between the weighing instrument receiving portions 11 and 11 and the tread 12, and the switch 21 is pressed.

Thus, the weight is digitally displayed on the display window 31 of the display device 3.

That is, as shown in FIG. 3 and FIG. 4, when the weighing instrument 2 is inserted, the footboard 12 which has been on the weighing instrument receiving portions 11, 11 until now is separated from the weighing instruments 11, 11 as shown in phantom lines. , The lifting guides 23, 23 on the upper plate B lift up the load, and the load cell C bears the load of the animal (not shown) and the tread 12 and is measured.

When the weighing instrument 2 is inserted, the trailing edge of the tread 12 comes into contact with the cage 1, but there is almost no weighing error.

The scale receivers 11 and 11 may be L-shaped or a bottom plate as in the conventional product, but if the sloped crosspiece is used as in the embodiment, feces will not be accumulated and it will be easy to wash even if it adheres, which is hygienic. .

Further, both sides of the footboard are bent downward for the same reason, and for facilitating the detachment from the receiving portion during lifting.

Further, the reason why the measuring device receiving portions 11, 11 are used as the crosspieces is to position the measuring device 2 in cooperation with the positioning guides 24, 24 provided on the lower surface of the measuring device to improve the measurement accuracy.

[Different Examples]

In the illustrated embodiment, the weighing device is of a drawer type,
It is also possible to adopt a model in which a weighing instrument and a display device are integrated and a caster at the bottom is inserted under the floor or footboard.

〔The invention's effect〕

According to the present invention, the weight can be measured extremely labor-saving and efficiently without leaving the animal in the cage.

When the scale is inserted into the cage, it is guided by the guide so that it does not touch the side wall surface.

Do not damage the claws of small animals when moving the scale in and out.
