Abstract: An appliance includes a handle, a speculum tube extending axially from the handle as far as a distal end where it has an opening, a video viewing system having a lens arranged in the speculum tube and a transmission device connected to the lens and connectable to a remote viewing screen, and a lens support for keeping the lens in a predetermined position with respect to the speculum tube, in which position the lens is near the opening and opposite the space situated beyond the opening, characterized in that the speculum tube has an end part and a main part extending between the end part and the handle, the end part being arranged around the support and delimiting the opening, the end part being elastically deformable and the main part being rigid.

Abstract: A straw includes a tube (11), a stopper (13) arranged in the tube and having a passage (35) extending through it, and an emptying needle (14) having a first portion (31) protruding from the stopper as far as a distal end (19) situated in the tube, and a second portion (32) situated in the passage (35) of the stopper, the needle and the stopper forming an insert (12) entirely disposed in the tube and having an internal conduit (24) fluidically connecting the internal spaces of the tube that are situated to either side of the insert, the internal conduit being formed at least in part by the needle. A method for emptying the straw includes establishing a fluidic communication between the needle and a receptacle, and making an opening in the tube in order to connect the dose of liquid-based substance to the atmosphere and allow it to flow.

Abstract: The appliance comprises a handle, a speculum tube (23) extending axially from the handle (21) as far as a distal end (22) where it has an opening (28), a video viewing system having a lens (35) arranged in the speculum tube and a transmission device (36) connected to the lens and connectable to a remote viewing screen, and a lens support (49) for keeping the lens (35) in a predetermined position with respect to the speculum tube, in which position the lens is near said opening (28) and opposite the space situated beyond said opening (28), characterized in that said speculum tube has an end part (26) and a main part (27) extending between said end part and said handle, said end part (26) being arranged around said support (49) and delimiting said opening (28), said end part (26) being elastically deformable and said main part (27) being rigid.
