- This instrument is for example a veterinary instrument used to simultaneously distribute two liquid products which are for example chemically incompatible, in order to ensure their mixing after their release from this instrument, in particular directly into the mouth of a pet such as a cat or a dog.
- This instrument 10 comprises a first compartment 11 and a second compartment 16.
- the first compartment 11 has for example an end with a first outlet orifice 12 and an open opposite end 13.
- a first compression piston 14 can be mounted in this first compartment in particular by making a sealed contact with the interior of this compartment.
- the first piston 14 may comprise a so-called actuating end 15, oriented opposite the first outlet orifice 12.
- Said first compression piston 14 and said first compartment 11 define for example a first chamber 23 for receiving a first liquid product.
- the first compartment 11 may be made of plastic or glass.
- the second compartment 16 may be distinct and initially separate from the first compartment 11.
- the second compartment 16 has for example an end with a second outlet orifice 17 and an open opposite end 18.
- a second compression piston 19 may be mounted in this second compartment 16 in particular by making a sealing contact with the interior of this compartment.
- the second piston 19 may comprise a so-called actuating end 20, oriented opposite the second outlet orifice 17.
- the second compression piston 19 and the second compartment 16 define for example a second chamber 24 for receiving a second liquid product.
- the second compartment 16 may be made of plastic or glass.
- the first and second compartments 11, 16 can be assembled by being arranged side by side or in parallel.
- the first compartment 11, and more precisely the body of the first compartment can comprise wing-shaped extensions 21 extending laterally to this first compartment 11 and placed opposite.
- a housing 27 is thus defined in which the second compartment 16 can be received for example by clipping.
- the instrument 10 comprises a barrier element 22 to prevent purely manual actuation of the first piston 14.
- the barrier element 22 may comprise an elongated hollow body placed in the extension of the upper end, or even of the open opposite end 13, of the first compartment 11, and more precisely of the body of the first compartment.
- the elongated hollow body 22 and the first compartment 11 may be formed from a single piece, for example made of plastic material, for example transparent.
- the barrier element 22 and the first compartment 11 may be formed from a single piece, for example made of plastic material, for example transparent.
- the elongated hollow body 22 may have a tubular shape, for example open on one of its sides so as to form a lateral opening 25. It may thus partially enclose a so-called external portion of the first piston 14.
- the so-called external portion corresponds to the part of the first piston located outside the first compartment 11.
- the first piston 14 is shown here in its fully retracted position.
- the lateral opening 25 of the elongated hollow body 22 can extend above the so-called actuating end 15 of the first piston 14 when the latter is in its fully retracted position, so that it is impossible for the user to actuate this first piston 14 inadvertently.
- the first chamber 23 of this first compartment 11 receives for example the appetizing matrix, thus ensuring no loss of appetizing matrix or that the latter cannot be delivered alone.
- the so-called actuating ends 15, 20 of the first and second pistons 14, 19 have, for example, complementary shapes so that they can be assembled by form engagement to form a common actuating head 26 allowing the simultaneous actuation of these pistons.
- these so-called actuating ends 15, 20 can be shaped to ensure the movement of the common actuating head 26 for the actuation of the pistons 14, 19 through the lateral opening defined by the elongated hollow body 22.
- the outlet orifice 12 of the first compartment 11 may be off-center, or even offset to the side, to bring the outlet orifices 12, 17 of the two compartments 11, 16 closer together.
- the spacing between these outlet orifices 12, 17 is less than or equal to 1.5 cm, preferably less than or equal to 1.0 cm or even more preferably, less than or equal to 0.5 cm.
- the outlet orifices 12, 17 of the first and second compartments 11, 16 also have different diameters to differentiate these outlet orifices and form a foolproofing device. This avoids any error in filling the corresponding compartments.
- the common actuating head 26 may comprise a main axis passing through the so-called actuating ends 15, 20 of the pistons 14, 19.
- the main axis may be arranged transversely or substantially transversely to the lateral opening 25.
- the second compartment 16 makes it possible to collect a quantity of second liquid product B adjustable to the weight of the animal in mL/kg while the first compartment 11 is controlled by the second compartment 16 so as to collect a quantity of first liquid product A proportional to the second liquid product B in ratios B:A for example of 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9 or even 1:10.
- the ratio is variable according to the dimensions of the first and second compartments 11, 16.
- the volume of liquid product stored in the second compartment 16 receiving the liquid product B is between 1 - 10 mL or 1 - 5 mL or even 1 - 2 mL.
- the volume of liquid product stored in the second compartment is for example 5 mL or 1 mL.
- the common actuating head 26 of the pistons can make it possible to dose each liquid product at a rate of 0.05 - 0.25 mL/kg for the product contained in the second compartment 16 and 0.1 to 1 mL/kg for the liquid product contained in the first compartment 11.
- the instrument thus makes it possible to dose very precise volumes.
- the precision of the graduation for the dosage in the second compartment 16 is 0.05-0.25 mL, preferably 0.05 to 0.1 mL, for example 0.05 mL.
- the instrument for dispensing a first product and at least one second product may comprise connection means, such as pipes 83, 84 illustrated with reference to FIG. 9. It should be noted that these pipes 83, 84 are not necessarily integrated into a base such as illustrated in FIG. 9.
- FIGs. 5 and 6 are a schematic representation of an instrument 50 for dispensing a first product and at least one second product according to another embodiment of the present invention.
- the elements of the instrument 50 shown in Figs. 5 and 6 bearing the same references as the elements of the instrument 10 illustrated in Figs. 1 to 4 represent the same objects, which will not be described again below.
- the instrument 50 shown in Figs. 5 and 6 differs from that illustrated in Figs. 1 to 4, in that the so-called actuating ends 51, 52 of the pistons have complementary shapes to ensure their assembly by engagement, which are of a different configuration. In particular, they are less wide, the lateral opening of the longitudinal hollow body 53 being narrower here.
- the cross section of the housing defined by the lateral extensions 54 and the outer wall of the first compartment is also substantially different in being more rounded and therefore closer to a C than to a U.
- FIGs. 7 to 9 illustrate a base 70, 80 for simultaneously loading the compartments of an instrument for dispensing a first product and a second product, called a double-compartment instrument, according to three variant embodiments.
- Each of these bases 70, 80 may comprise supports for connecting thereto, for example, two containers 71, 72, 81, 82.
- Each base 70, 80 may comprise a base 88 for receiving and supporting a double-compartment instrument.
- Each base 70, 80 may comprise liquid supply circuits that are entirely distinct, the liquid supply circuits being configured to be supplied by the containers 71, 72, 81, 82.
- Each of these liquid supply circuits may for example comprise a pipe 83, 84, opening at its other end onto a corresponding orifice 73, 74, 85, 86 of the receiving base 88 and for supporting a double-compartment instrument.
- the supply circuits and more particularly the pipes 83, 84, form means for connecting the first and second compartments 11, 16, to the containers 71, 72, 81, 82.
- the orifices 73, 74, 85, 86 of this receiving and supporting base 88 are intended to receive and be connected for example by plugging with the ends of the compartments comprising the outlet orifices 12, 17.
- the outlet orifices can be in the form of plugs, or pins.
- the orifices 73, 74, 85, 86 can thus form a sort of socket on which the instrument to be filled is connected.
- the orifices 73, 74, 85, 86 of this receiving and support base 88 may have different diameters, each corresponding to the diameter of the outlet orifice 12, 17 of a respective compartment 11, 16 to provide a foolproofing function.
- the orifices 73, 74, 85, 86 of this receiving and support base 88 can be hermetically sealable using a plug 87, for example screwed.
- This plug 87 can come from one of the containers 71, 72, 81, 82.
- At least one of the containers 71, 72, 81, 82 may be a solution storage bag.
- FIGs. 10 to 11 illustrate a base 90 for simultaneously loading the compartments of an instrument for dispensing a first product and a second product, called a dual-compartment instrument, according to a fourth embodiment.
- the base 90 shown in Figs. 10 and 11 differs essentially from those shown in Figs. 7 and 9 in that its receiving and supporting base 91 comprises a support 92 for receiving the instrument 10, 50 for dispensing a first product and at least one second product, between two uses of the latter. Furthermore, the conduits 93 of the receiving and supporting base 91 are removable so that they can be replaced at least in part by new conduits, when the instrument is intended to receive at least one new product.
