Straw for cryogenic preservation of a dose of liquid-based substance, assembly comprising same, and method for empty this straw

A device for preserving a predetermined dose of liquid-based substance, notably animal semen or a preservation medium containing embryos or tissue samples, comprises a tube () made of a weldable plastics material. The tube allows a service state in which a receiving portion () intended to contain the said predetermined dose has a circular cross-section whereas a sealing portion () comprises a welded pinch () and a transition zone (). Over at least part of the sealing portion a differentiating edge region () gives the external surface of the tube a visual appearance different from the visual appearance of the external surface of the tube outside of the differentiating edge region. A range comprises such a device and a similar device but without the differentiating edge region.

Device for preserving a predetermined dose of liquid-based substance, and range of such devices

The device () comprises an inlet element () comprising an interface () for connecting to an artificial vagina and delimiting an inlet opening (), a filter delimiting with the inlet element () an inlet chamber () on the side of the filter turned towards the opening () and a collection bag () extending between a closed end () and an open end () in which said inlet element is engaged; said bag and said filter delimiting a collection chamber () on the side of the filter turned towards the end (); by means of which the semen entering through the opening () passes through the filter and comes to the collection chamber (); the filter being a perforated wall () having a tubular portion () and a bottom portion () closing said tubular portion, and having a surface density of orifices () that is greater on said bottom portion than on said tubular portion.

Device for collecting animal semen

The straw comprises a tube () and a stopper () fixed relative to the tube () and comprising a male connector tip () configured in order that a syringe needle () having a female connector tip () with a frusto-conical internal surface in accordance with a standard can be connected to said stopper () by engagement of the female connector tip () of the needle on the male connector tip () of the stopper (). The injection device comprises such a straw () and a syringe needle (). The method of emptying the straw comprises the step of pushing the dose of liquid-based substance () packaged in the straw () towards the stopper ().

Straw for the preservation of a predetermined dose of liquid-based substance, as well as a method and injection device that employ it

The invention relates to a storage receptacle () with a longitudinal opening () through which straws () for packing liquid-based substance are passed in a predetermined orientation of the straws, a housing () provided for the straws and configured to be inserted slidably in a cover () of the receptacle, the latter having an open configuration, in which the housing is partially inserted in the cover and the opening is free for the passage of the straws, and a closure configuration, in which the housing is inserted in the cover and the opening is closed by the cover in order to prohibit the passage of the straws. The housing has a parallelepipedal shape, a first front wall in which the opening is formed, a first bottom wall, two first longitudinal wails extending parallel to the opening, and two first side walls which each have two diagonals of a length less than or equal to the length of the straws.

Storage receptacle for straws for packaging animal semen and processing installation comprising such a receptacle

The straw includes a tube () extending between a first end () and a second end () and includes a gas-permeable but liquid-impermeable plug (). The tube () is made of a thermochromic material that reversibly changes colour at a pre-set temperature threshold, by virtue of which colour change the tube () has a first visual appearance if the temperature thereof is below the preset threshold and a second visual appearance that is different from the first visual appearance if the temperature thereof is above the preset threshold.

The container straw comprises a tube () and a stopper () that is permeable to gasses and impermeable to liquids, which stopper () is arranged in the tube () near one end (), characterized in that it comprises an indicator component () configured to emit, at least when the container straw () is full, light the spectrum of which contains at least one spike having a peak of predetermined wavelength. The assembly comprises the container straw () and a container straw recognition device ().

The invention relates to a straw comprising a tube () extending between a first end () and a second end () and comprising a stopper () placed in the tube near the first end thereof and extending between a first end () facing the first end of the tube, and a second end () facing the second end of the tube, said stopper and said tube being configured such that, after a liquid substance () has come in contact with the stopper via the second end thereof, the stopper blocks the passage of the liquid substance therethrough and is, by pushing on the first end thereof, slidable into the tube toward the second end thereof. Moreover, the stopper comprises, on the side of the second end of the tube, a barrier pad () consisting of hydrophobic threads over the entire cross-section of the tube.
