Abstract: An automatic milking apparatus for laboratory animals that can facilitate and stabilize the positioning of a teat cup 20 is provided for full automation of a milking operation. An end of a first milk tube 12 attached to a teat cup 20 for laboratory animals is attached to a free end of a flexible arm A having one end fixed to a suitable base (milk collecting container stand B). The flexible arm A includes a laminated body 40 including a long member 41 formed of a material that is flexible and after being flexed, can maintain the shape (for example, a lead plate) and a steel plate member 42, the laminated body 40 being coated by a coating member 50, the members being in contact with each other in such a manner that they slip relative to each other upon being flexed in their entirety, the flexible arm A including a secured part 53 formed at the one end, the secured part 53 preventing relative movement of the respective members. The tip of the flexible arm A is not displaced after being positioned.

Abstract: Provided is a breast pump for the mother's milk, which makes it possible to obtain universal milk expression data without being affected by an individual difference, for example. The breast pump is composed of a collection container, a milk expressing member, and a negative pressure source for producing pulsated negative pressure. The milk expressing member is provided at an end with a teat cup and at an opposite end with a connector plug to the negative pressure source. The milk expressing member is divided by a partition plate. A flexible teat cup liner is replaceably fitted in the teat cup, and configured to be brought into contact with an areola and nipple of a breast.

Abstract: A milking apparatus for laboratory animals enables a milking operation to be performed on a laboratory animal (such as a rat) by a single experimenter, and also enables universal milking data to be obtained that is not influenced by individual difference among experimenters. A teat cup enables milking to be performed directly from the nipple of a relatively small and prolific laboratory animal such as a rat and mouse. The invention provides useful means for clarifying the influence of harmful extrinsic substances on living organisms via milk. The apparatus comprises a milk-collecting container 10 whose inside can be kept blocked from the outside air, two, i.e., a first and second, tubes 12, 13 inserted into the milk-collecting container in a communicated manner, and a teat cup 20 replaceably mounted on the other end of the first tube 12.

Abstract: Provided is a breast pump for the mother's milk, which makes it possible to obtain universal milk expression data without being affected by an individual difference. By the breast pump according to the present invention, exogeneous toxic substances in the mother's milk can be detected.
