Abstract: A device for mechanical fragmentation of tissues facilitates preparation of the composition of isolated cells from a tissue sample, the preparation including mechanical fragmentation of the tissue, the device including a motorized support and a container, the motorized support including a motor having a rotor secured to a coupling member, the container internally including a rotary shaft with radial arms sweeping the inside of the container as the shaft rotates, the motorized support and the container including a complementary securing unit that allow the container to be immobilized on the motorized support, the coupling member and the rotary shaft being configured in such a way as to allow axial rotation of the rotary shaft when the rotor of the motor is turning. The radial arms are of two types: rigid vane-type arms, and flexible filamentary-type arms, notably made of nylon or of metal. A corresponding method is also disclosed.

Abstract: Disclosed is a vessel for recovering adipose tissues including a body sealed by a lid connectable to a first pipe with a suction cannula, and a second pipe with a suction pump. A removable adapter connects a lid including two orifices, each closed by a stopper that can be pierced or is pre-pierced and self-sealing, and a vent opening with a filter and removable plug. The connection adapter includes two rigid piercing tubes projecting from under the adapter, each piercing tube in continuous fluid relationship with a corresponding nipple projecting from the adapter, each nipple connectable to a corresponding pipe. The two sealed orifices of the lid and the adapter and piercing tubes are arranged so, when the connection adapter is applied to the lid, each piercing tube pierces a corresponding stopper and brings each nipple into correspondence, in a sealed manner, with the internal volume of the vessel.

Abstract: A syringe for medical applications includes a syringe body having an inner wall, a first stop, located along the inner wall, to leave at least one first blank surface on the inner wall; and a plunger sliding along the inner wall of along a longitudinal axis of the syringe, the plunger including a plunger head and an operating rod, connected to the plunger head, including, on its outer surface, at least one first rack arranged longitudinally along the operating rod, the first rack including protruding teeth. The first stop and the protruding teeth are also shaped and constituted so as to prevent the plunger from lowering again due to pressure on the operating rod, unless the first rack is disengaged by rotating the plunger within the syringe body around the longitudinal axis so that the first rack faces the first blank surface of the inner wall of the syringe body.
