Abstract: The disclosure concerns an automatic machine for metering and filling, for example volumes of animal semen, in any packaging member, regardless of its diameter and the material from which it is made (straws, glass or plastics material catheters, all types of flask, etc). Essentially intended for artificial insemination of poultry, for example turkeys, this device nevertheless has an extremely wide range of application. For example, using a peristaltic cassette (12) (described, for example, in U.S. Pat. No. 4,702,679 filed by MALBEC), under the control of a digital controller, the machine enables small volumes of liquid to be dispensed with the greatest possible accuracy and very high rates of artificial insemination to be maintained. The objectives of the invention include a device for precise and fast metering of any fluid, primarily for use in animal husbandry and research laboratories.

Abstract: A device for collecting seminal fluid, comprises a collecting container (1) on which is mounted an adaptor (2) provided with a cannula (3) for sucking up the seminal fluid under the effect of a partial vacuum. The device further includes an adaptor sleeve (5) interposed between the container (1) and the adaptor (2). The sleeve comprises a chamber (10) in communication with the adaptor (2) in which chamber a filter (11) for the seminal fluid is located. A pipe (16) for sucking up the fluid and having a first flared end portion (17) emerges on the filter (11) and a second end portion (18) emerges in the container via a projection (19) extending axially beyond the end (20) of the sleeve pointing towards the container. A sucking-up duct (21) intended to be connected to a source of partial vacuum terminates at the end (2) of the sleeve inside the container in order to generate, within the container (1), a partial vacuum intended to bring about the sucking-up of the seminal fluid through the filter (11).
