Description

【Technical Field】 【0001】 The present invention relates to a medical or veterinary instrument for simultaneously lifting and dispensing at least two products. 【0002】 The present invention further relates to a syringe for use with such a medical or veterinary instrument. 【0003】 The present invention also relates to a stand that enables each of the products to be dispensed to be simultaneously lifted from compartments of the instrument. 【Background Art】 【0004】 Pets such as cats or dogs require medications to be administered orally at some point in their lives. 【0005】 By way of example, it is known that in order to maintain the health of a cat or dog, it is necessary to periodically administer an oral anthelmintic such as a liquid anthelmintic. In other cases, antibiotics may be required. 【0006】 However, oral administration, particularly in cats, can be a significant challenge. 【0007】 It is difficult to make a pet ingest an unfamiliar product that may not taste good. 【0008】 It is known to hide the drug in a small amount of food in anticipation that the pet will ingest it. 【0009】 However, it has been observed that pets, particularly cats, can detect the ruse by their highly developed sense of smell and avoid a piece containing the drug. 【0010】 Furthermore, some of these liquid medications must be administered to the pet on an empty stomach, making it impossible for them to be hidden by the smell of solid food. 【0011】 This liquid medication can be mixed with another liquid product that is very palatable to pets, ensuring they ingest it. 【0012】 However, for certain veterinary applications, these liquid products may be chemically incompatible, making it impractical to prepare ready-to-use mixtures. Furthermore, active ingredients are not always chemically stable in liquid media, and bait formulations further destabilize these components in liquid media. 【0013】 Therefore, pet owners must prepare this mixture immediately before administration. 【0014】 Furthermore, it may be essential to take into account at least one parameter of the pet, such as its weight, to achieve the most accurate mixture possible. 【0015】 This requirement necessitates careful handling of the product before introducing it into a syringe and administering and mixing it to the pet orally. 【0016】 This results in longer preparation times, which can also be tedious for the preparer if it is repeated regularly. 【0017】 Furthermore, errors in the administration and loss of the active product may occur during preparation. 【0018】 Therefore, it would be beneficial to have a device for sampling and administering drugs and palatable substrates to animals that has a unique design that overcomes the aforementioned shortcomings. [Overview of the project] 【0019】 Subject of the invention The present invention relates to a medical or veterinary instrument that can lift at least two products simultaneously and separately, house these products separately, deliver these products simultaneously or together, hold these products separately until they leave the instrument, and administer, for example, these products directly into the mouth of livestock, or into the mouth of a riding animal, working animal, or grazing animal. 【0020】 The object of the present invention is to provide a medical or veterinary device that is simple to design, economical, and highly reliable when administering at least two products, such as liquid products. 【0021】 Another object of the present invention is a medical or veterinary instrument that prevents unintended operation of a control rod or piston of a first compartment containing the first product, thereby preventing the accidental delivery of the first product to an animal without simultaneously distributing a second product intended to be delivered at the same time as the first product, or preventing the accidental loss of the first product. 【0022】 The present invention further relates to a syringe for use in such medical or veterinary instruments. 【0023】 The present invention further relates to a stand that is particularly easy to use and design, and that allows for the simultaneous filling of each product into the compartments of the medical or veterinary instrument. 【0024】 Disclosure of the invention For this purpose, the present invention relates to an apparatus for dispensing a first product and at least one second product, each of which is liquid or viscous. 【0025】 According to the present invention, this device is - A first section having one end with a first outlet orifice and an opposite open end, wherein a first compression piston is mounted within the first section, the first piston having a so-called working end, and the first compression piston and the first section define a first chamber for receiving a first product, the first section, - A second section separate from the first section, the second section having one end with a second outlet orifice and an opposite open end, wherein a second compression piston is mounted within the second section, the second piston having a so-called working end, and the second compression piston and the second section define a second chamber for receiving a second product, the second section, and - The first section includes a barrier element for preventing purely manual operation of the first piston. - A connecting device couples the first piston and the second piston, thus forming a common working head of the pistons, whereby the pistons are moved simultaneously when the common working head is pushed or pulled. - The barrier member and the connecting device are configured to allow the connecting device to move through at least a portion of the barrier member during movement of the working head to enable operation of the first piston. 【0026】 "Purely manual operation" or "direct manual operation" means that the first piston is moved solely and manually, i.e., directly by one or more of the operator's fingers. 【0027】 In this sense, the barrier element is designed to prevent the operator from accessing at least the working end of the first piston and directly operating the first piston with at least one of the operator's fingers. 【0028】 The present disclosure is not limited to embodiments of medical or veterinary devices for simultaneously dispensing two liquid products, and it should be noted that it also addresses other types of products, such as the simultaneous dispensing of a liquid product and a viscous product, or two viscous products. 【0029】 According to certain embodiments, the device enables the simultaneous dispensing of these two products and ensures their direct mixing in the mouth of livestock, or in the mouth of a riding animal, working animal, or grazing animal. 【0030】 It should also be noted that the present disclosure is not limited to the simultaneous dispensing of only two products and can be very well related to the dispensing of at least three products. What has been actually presented for an assembly comprising a syringe assembled in a first compartment can be adapted to at least one additional syringe assembled in the first compartment. 【0031】 For purposes of illustration only, a further lateral opening can be added on another side of the first compartment, and a connecting device can be provided to join the so-called working ends of the pistons mounted in the various compartments thus assembled. 【0032】 It should also be noted that these two compartments may be pre-assembled or may initially be separate compartments that can be joined to each other by at least one element joining these compartments. 【0033】 The working or proximal end of the piston, also called the head, can be characterized by a finger placement surface, and as a result, it is well known that the piston can comprise a rod, a head, and a finger placement in one and the same part. 【0034】 Advantageously, when dispensing two products, the medical or veterinary device of the present disclosure enables the physical separation of a substrate providing palatability or superpalatability and a formulation containing an active ingredient, so that the formulation remains stable over time, and thanks to this device, which is very easy to use for the animal owner, it ensures their simultaneous removal and dispensing. 【0035】 This device is suitable for all types of liquid oral medications. The highly palatable substrate, with its creamy liquid texture, is available in several flavors / formulations to overcome the problem of cats losing interest, and owners can change the flavor / formulation as needed. 【0036】 The features of the devices described in this disclosure can be implemented separately or in combination with each other, as desired. 【0037】 This disclosure also relates to apparatus for dispensing a first product and at least one second product, each of which is liquid or viscous. 【0038】 According to the present invention, this device is -A first compartment having one end with a first outlet orifice and the opposite open end, wherein a first compression piston is mounted within the first compartment, the first piston has a so-called operating end, and the first compression piston and the first compartment define a first chamber for receiving a first product, -A second compartment, separate from the first compartment, having one end with a second outlet orifice and the opposite open end, a second compression piston mounted within the second compartment, the second piston having a so-called operating end, and the second compression piston and the second compartment comprising a second compartment defining a second chamber for receiving a second product, - The first compartment is extended on its opposite open end by an elongated hollow body that partially surrounds the portion of the first piston located outside the first compartment when the first piston is in a fully retracted position, and the elongated hollow body is at least partially open on one of its sides, defining a longitudinally extending lateral opening. - The device comprises a connecting device for connecting a first piston and a second piston, thereby forming a common working head for the pistons, so that the pistons move simultaneously when the common working head is pushed or pulled. - The connecting device is configured to traverse at least a portion of the lateral opening when the common operating head is pushed or pulled. 【0039】 Therefore, according to this embodiment, the barrier element comprises an elongated hollow body that extends the first compartment toward the opposite open end. 【0040】 According to a particular embodiment of a device for dispensing a first product and at least one second product, the connecting device and the barrier element are configured such that the connecting device performs translational motion when the working head is moved. 【0041】 Preferably, when the working head is moved under manual impulse by the operator or the actuator, the connecting device thus translates within the barrier element. 【0042】 According to another particular embodiment of the apparatus for dispensing a first product and at least one second product, the barrier element surrounds the first piston to mask at least a portion of the first piston having its operating end, at least in the fully retracted position of the first piston and over an angular sector extending at a predetermined angle around an axis passing through the first piston, the angle defining the axial passage opening of the connecting device. 【0043】 According to yet another specific embodiment of a device for dispensing a first product and at least one second product, the connecting device is arranged to connect the so-called working ends of the first and second pistons and thus form a common working head of the pistons. 【0044】 Advantageously, the connecting device allows the so-called working ends of the pistons to be linked together, thus forming a common working head for these pistons, and as a result, the products present in the compartments are distributed incidentally or even simultaneously. The lateral openings of the elongated hollow body allow the device to be operated by moving the connecting device and thus the working head, pushing the pistons and simultaneously discharging the products contained in the corresponding compartments or drawing in products to fill those compartments. 【0045】 Alternatively, each of the first and second pistons may be provided with a rod, and the connecting device may be configured to connect the rods of the first and second pistons. 【0046】 In certain embodiments, the coupling device is positioned near the operating end of the piston so as not to restrict the stroke of the piston within each compartment. 【0047】 For illustrative purposes only, the connecting device may take the form of an arm having a ring with an open end for receiving a piston rod by clip fastening. 【0048】 According to yet another specific embodiment of a device for dispensing a first product and at least one second product, the lateral opening is a slot defining a guide rail, and the connecting device is configured to move along the guide rail when the working head is actuated, and thus guide the movement of the piston. 【0049】 This ensures that the working head moves in a straight line. 【0050】 According to yet another specific embodiment of a device for dispensing a first product and at least one second product, at least a portion of the lateral opening, preferably the portion located on the side of the so-called working end of the corresponding piston, has a key shape, and as a result has the shape or configuration necessary to allow only a connecting device formed by the joining of the so-called working ends of the pistons of two predetermined compartments to move along at least a portion of the lateral opening when the common working head is actuated. 【0051】 In other words, if this required shape or configuration is not achieved, the key shape of the lateral opening will prevent the piston from operating. 【0052】 According to yet another specific embodiment of the apparatus for dispensing a first product and at least one second product, the elongated hollow body is configured to prevent at least one finger from accessing the so-called operating end of the first piston. 【0053】 Since the piston in the first compartment is inaccessible to the user's fingers, this prevents the contents of the first compartment from being accidentally dispensed, thus ensuring that, for example, any loss of the product is avoided. 【0054】 The connecting device that links the so-called operating ends of the pistons ensures that the products contained within the first compartment cannot be delivered or distributed on their own. 【0055】 Furthermore, thanks to the single operation, it is guaranteed that both products will be dispensed simultaneously, and as a result, the ratio between each product is respected. 【0056】 Preferably, at least a portion of the elongated hollow body has a tubular shape, the lateral opening extends to the free end of the elongated hollow body, and optionally, the elongated hollow body has a flared shape. 【0057】 According to yet another particular embodiment of a device for dispensing a first product and at least one second product, the first section defines a first main body spindle, the second section defines a second main body spindle, and the device comprises at least one element for joining the first section and the second section, the at least one joining element configured to keep the first spindle and the second spindle aligned or substantially aligned on the same reference axis in which the working head is central or substantially central. 【0058】 Advantageously, this ensures that each piston is precisely centered on the axis of the compartment in which it is installed, thereby avoiding any accidental halts in the forward movement of the piston within that compartment due to blockage. Thus, it is possible to distribute the entire contents of the chamber into the corresponding compartment. 【0059】 Preferably, the first compartment has a lateral extension that defines a lateral housing for receiving and holding the second compartment. 【0060】 Advantageously, purely illustrative, the lateral extensions, together with the outer wall of the first compartment, define a housing having a substantially U-shaped cross-section, and each wing, i.e., branch of the U, is flexible or elastically deformable to ensure access to the corresponding housing. 【0061】 In certain embodiments, the wing portion further forms a clipping mechanism together with the second section. In other embodiments, at least one additional fastening element is provided to join the two sections together and keep them connected. 【0062】 This type of design also allows the use of conventional commercially available syringes that are accepted and mounted in the first compartment. In this case, the connecting device is an insert. 【0063】 According to yet another specific embodiment of the apparatus for dispensing a first product and at least one second product, the so-called working ends of the first and second pistons are formed to join with each other, thereby defining the common working head of the pistons. 【0064】 Therefore, the connecting device is formed by the operating ends of the piston, and these operating ends are shaped to join with each other, thus defining this common operating head of the piston. 【0065】 Advantageously, one so-called working end of the piston is provided with a female connecting element such as a hollow portion, and the other so-called working end of the piston is provided with a male connecting element such as a protruding portion having a shape complementary to the hollow portion, and the male and female connecting elements have complementary shapes to ensure their assembly through shape engagement. 【0066】 According to yet another specific embodiment of a device for dispensing a first product and at least one second product, the connecting device is an insert configured to connect a first piston and a second piston. 【0067】 In this way, a conventional commercially available syringe, which may be pre-filled, is received and installed in the first compartment. 【0068】 Advantageously, the insert has an inner surface with an opening that provides access to a housing, each sized to receive the so-called working end of the corresponding piston. 【0069】 According to yet another specific embodiment of a device for dispensing a first product and at least one second product, at least one of the outlet orifices of the compartment is offset from the body axis of the corresponding compartment, bringing the outlet orifices spatially closer to each other, thereby separating the outlet orifices by a maximum distance of, for example, 1.5 cm, preferably 1 cm, and even more preferably 0.5 cm. 【0070】 Preferably, the first compartment includes at least one element for joining the first compartment and the second compartment, so that the outlet is positioned on the side of the at least one connecting element so as to be close to the outlet of the second compartment and thus connected to the first compartment. 【0071】 According to yet another specific embodiment of the apparatus for dispensing a first product and at least one second product, the first and second compartments are cylindrical. 【0072】 Preferably, at least a portion of the elongated hollow body is also cylindrical. 【0073】 According to yet another specific embodiment of the apparatus for dispensing a first product and at least one second product, the first compartment and the elongated hollow body and / or the connecting device and the piston are formed in the state of one identical part. 【0074】 Here, "the first compartment and the elongated hollow body are formed in the same part" or "the connecting device and one of the pistons are formed in the same part" means that they are a single object. 【0075】 For illustrative purposes only, they are obtained by molding plastic materials. 【0076】 According to yet another particular embodiment of a device for dispensing a first product and at least one second product, the device includes connecting means configured to receive the end of a compartment, each having an outlet orifice, and to arrange these outlet orifices in fluid communication with a first container containing the first product to be dispensed and a second container containing the second product to be dispensed, respectively. 【0077】 As an example, the base is configured to receive and support the ends of the compartments, each having an outlet orifice, and to position these outlet orifices to be in fluid communication with the corresponding internal ducts, the internal ducts being connected to and in fluid communication with insert containers for supplying the respective products to the corresponding compartments. 【0078】 Alternatively, these internal ducts may open on the opposite side of the base that receives the end of the compartment. The base is configured to keep the first and second main shafts of the compartment aligned on the same reference axis, or substantially aligned, with the working head at its center or substantially at its center. 【0079】 According to yet another specific embodiment of the apparatus for dispensing a first product and at least one second product, the apparatus allows for dosage correction / modification. 【0080】 In certain embodiments, the chamber volume of the first compartment (intended to contain the composition containing the active ingredient) is 5 to 60 mL, preferably 5 to 50 mL, and more preferably 10 to 50 mL, for example, 18 mL, 20 mL, 25 mL, or 50 mL. 【0081】 The chamber volumes of the other compartments (intended to contain palatable substrates) are 10-300 mL, 10-250 mL, or 20-200 mL, more preferably 40-180 mL, and even more preferably 60-120 mL, for example, 60 mL, 80 mL, 100 mL, 240 mL, and 300 mL. 【0082】 The present invention further relates to a syringe for an apparatus for dispensing the first product and at least one second product as described above. 【0083】 According to the present invention, - The syringe comprises a compartment having an outlet orifice at one end and an open end on the opposite side, a compression piston mounted within this compartment, the piston having a so-called operating end, and the compression piston and the compartment define a chamber for receiving the product. - The compartment is provided with a barrier element to prevent purely manual operation of the first piston, the barrier element is configured to allow movement of a connecting device to another piston through at least a portion of the barrier element, and the compartment is manufactured as a single unit. 【0084】 The present invention further relates to a syringe for an apparatus for dispensing the first product and at least one second product as described above. 【0085】 According to the present invention, -This syringe comprises a compartment having an outlet orifice at one end and an open end on the opposite side, a compression piston mounted within this compartment and in sealed contact with the inside of the compartment, the piston having a so-called working end, and the compression piston and the compartment define a chamber for receiving the product. - The compartment is extended on the opposite side of its open end by an elongated hollow body that partially surrounds the portion of the piston located outside the compartment when the piston is in the fully retracted position, and the elongated hollow body is at least partially open on one of its sides, defining a longitudinally extending lateral opening. - The elongated hollow body is configured to prevent at least one finger from accessing the so-called operating end of the first piston. 【0086】 Therefore, the barrier element comprises an elongated hollow body that extends the first compartment toward the opposite open end. 【0087】 When the piston is in its fully retracted position, the seal at the distal end of the piston is closest to the open end on the opposite side of the corresponding compartment. 【0088】 In certain embodiments of the syringe, the elongated section and the hollow body are formed in the same component. 【0089】 According to another specific embodiment of the syringe, the compartment has a main axis, and the exit orifice of the compartment is off-center from this main axis. 【0090】 According to yet another specific embodiment of the syringe, the so-called working end of the piston comprises a female connecting element, such as a hollow portion, shaped to complement a male connecting element located at the so-called working end of another piston, or a male connecting element, such as a projection, shaped to complement a female connecting element located at the so-called working end of another piston, thereby ensuring the assembly of the so-called working ends of these pistons through shape engagement. 【0091】 The present invention also relates to a stand for simultaneously loading the first and second compartments of a device for dispensing a first product and at least one second product, as described above, with their respective liquid or viscous products. 【0092】 According to the present invention, this stand is -

[Modes for carrying out the invention] 【0098】 The drawings and the following description contain elements of a certain nature. Therefore, they may not only help to better understand the invention but also, where appropriate, contribute to its definition. 【0099】 First, please note that the drawings are not to scale. 【0100】 Figures 1 to 5 schematically show a device for dispensing a first product and at least one second product according to a particular embodiment of the present invention. 【0101】 This instrument is a veterinary instrument used, for example, to dispense two liquid products, such as chemically incompatible ones, simultaneously, to ensure that they are mixed after being dispensed from this instrument, particularly directly into the mouths of pet animals such as cats or dogs. 【0102】 This device 10 comprises a first compartment 11 and a second compartment 16. 【0103】 The first compartment 11 has, for example, one end having a first outlet orifice 12 and an open end 13 on the opposite side. A first compression piston 14 can be mounted in the first compartment, particularly by making sealed contact with the interior of the compartment. The first piston 14 may have an operating end 15 facing away from the first outlet orifice 12. The first compression piston 14 and the first compartment 11 define, for example, a first chamber 23 for receiving a first liquid product. The first compartment 11 can be made of plastic or glass. 【0104】 The second compartment 16 is separate from the first compartment 11 and may initially be separated. The second compartment 16 has, for example, one end having a second outlet orifice 17 and the opposite open end 18. A second compression piston 19 can be installed in the second compartment 16, particularly by making sealed contact with the interior of this compartment. The second piston 19 may have an operating end 20 facing away from 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 can be made of plastic or glass. 【0105】 The first section 11 and the second section 16 can be assembled in parallel or side-by-side arrangement. For this purpose, the first section 11, more precisely the body of the first section, may have a wing-shaped extension 21 that extends laterally to the first section 11 and is positioned on the opposite side. The housing 27 is thus defined, and the second section 16 can be clipped into it, for example. 【0106】 The device 10 includes a barrier element 22 to prevent purely manual operation of the first piston 14. 【0107】 The barrier element 22 may include an elongated hollow body extending from the upper end of the first compartment 11, or from the opposite open end 13, or more precisely, from the body of the first compartment. 【0108】 The elongated hollow body 22 and the first compartment 11 can be formed from a single piece of material, for example, from transparent plastic. 【0109】 The barrier element 22 and the first compartment 11 can be formed from a single piece of material, for example, from transparent plastic. 【0110】 The elongated hollow body 22 may have a tubular shape, for example, with one side open to form a lateral opening 25. Thus, it can partially enclose the outer portion of the first piston 14. The outer portion corresponds to the portion of the first piston located outside the first compartment 11. The first piston 14 is shown here in its fully retracted position. 【0111】 The lateral opening 25 of the elongated hollow body 22 can extend above the so-called operating end 15 of the first piston 14 when the first piston 14 is in its fully retracted position, thereby making it impossible for the user to accidentally operate the first piston 14. 【0112】 The first chamber 23 of this first compartment 11, for example, accepts a palatable substrate and thus ensures that the palatable substrate is not lost or delivered unintentionally. 【0113】 The so-called operating ends 15, 20 of the first piston 14 and the second piston 19 may, for example, have complementary shapes, and as a result, they may be assembled by shape-fitting engagements to form a common operating head 26 for the simultaneous operation of these pistons. 【0114】 Furthermore, these so-called operating ends 15, 20 can be shaped to ensure that a common operating head 26 for acting the pistons 14, 19 moves through a lateral opening defined by an elongated hollow body 22. 【0115】 Advantageously, cooperation may exist between the shape of the common operating head 26 and the lateral opening 25 of the elongated hollow body 22 in order to guide the movement of the common operating head 26. 【0116】 Therefore, by pushing the common operating head 26 from the fully retracted position of each piston to the discharge position, the liquid products contained in the first compartment 11 and the second compartment 16 are simultaneously distributed or discharged. By pulling the common operating head 26 backward from the discharge position, the product is simultaneously drawn in or drawn up from each of the compartments. 【0117】 The outlet orifice 12 of the first section 11 may be offset or shifted laterally to bring the outlet orifices 12 and 17 of the two sections 11 and 16 closer together. Preferably, the distance between these outlet orifices 12 and 17 is 1.5 cm or less, preferably 1.0 cm or less, or even more preferably 0.5 cm or less. 【0118】 The exit orifices 12 and 17 of the first compartment 11 and the second compartment 16 also have different diameters to distinguish these exit orifices and form an encoding device. This prevents the corresponding compartments from being filled incorrectly. 【0119】 The common working head 26 may include a spindle through which the so-called working ends 15, 20 of the pistons 14, 19 pass. The spindle can be positioned laterally or substantially laterally with respect to the lateral opening 25. 【0120】 The second compartment 16 allows for the dispensing of a second liquid product B in an amount adjustable to the animal's body weight in mL / kg, while the first compartment 11 is subordinate to the second compartment 16, dispensing a first liquid product A in an amount proportional to the second liquid product B. A is, for example, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, or 1:10. This ratio varies depending on the dimensions of the first compartment 11 and the second compartment 16. 【0121】 For illustrative purposes only, the volume of the liquid product stored in the second compartment 16 receiving liquid product B is between 1 and 10 mL, or between 1 and 5 mL, or between 1 and 2 mL. The volume of the liquid product stored in the second compartment is, for example, 5 mL or 1 mL. 【0122】 The common piston operating head 26 can dispense each liquid product at a rate of 0.05 to 0.25 mL / kg for products contained in the second compartment 16, and at a rate of 0.1 to 1 mL / kg for liquid products contained in the first compartment 11. Therefore, this device can be used to dispense very precise amounts. 【0123】 For illustrative purposes only, the precision of the scale for administration in the second compartment 16 is 0.05 to 0.25 mL, preferably 0.05 to 0.1 mL, for example 0.05 mL. 【0124】 The apparatus for distributing the first product and at least one second product may include connecting means such as ducts 83 and 84 shown in Figure 9. These ducts 83 and 84 do not necessarily need to be integrated into the stand as shown in Figure 9. 【0125】 Figures 5 and 6 are schematic diagrams of a device 50 for dispensing a first product and at least one second product, according to another embodiment of the present invention. 【0126】 The elements of the apparatus 50 shown in Figures 5 and 6, which have the same reference numerals as those of the elements of the apparatus 10 shown in Figures 1 to 4, represent the same object, which will not be described again below. 【0127】 The apparatus 50 shown in Figures 5 and 6 differs from those shown in Figures 1 to 4 in that the so-called working ends 51 and 52 of the piston have a different configuration, having complementary shapes to ensure their assembly through a shape-fitting engagement. In particular, the working ends are narrower because the lateral opening of the longitudinal hollow body 53 is narrower. 【0128】 The cross-section of the housing, defined by the lateral extension 54 and the outer wall of the first compartment, is also substantially different, more rounded, and therefore closer to a C shape than a U shape. 【0129】 Figures 7 to 9 show stands 70, 80 for simultaneously loading compartments of an apparatus for dispensing a first product and a second product, known as a dual-compartment apparatus, in three modified forms. 【0130】 Each of these stands 70, 80 may be provided with a support for connecting, for example, two containers 71, 72, 81, 82. Each stand 70, 80 may be provided with a base 88 for receiving and supporting a double compartment device. Each stand 70, 80 may be provided with a completely separate liquid supply circuit, which is configured to be supplied from containers 71, 72, 81, 82. Each of these liquid supply circuits may be provided with, for example, ducts 83, 84, which may open at the other end onto corresponding orifices 73, 74, 85, 86 of the base 88 for receiving and supporting the double compartment device. The supply circuits, more specifically the ducts 83, 84, form means for connecting the first compartment 11 and the second compartment 16 to containers 71, 72, 81, 82. 【0131】 Therefore, these liquid supply circuits 83 and 84 are completely isolated, and as a result, each instrument compartment 11 and 16 to be filled can be loaded with only a single corresponding liquid product. 【0132】 The orifices 73, 74, 85, and 86 of this base 88 are designed to accept the ends of compartments that house the outlet orifices 12 and 17, and to be connected, for example, by plugging them in. The outlet orifices can take the form of plugs or pins. Thus, the orifices 73, 74, 85, and 86 can form a kind of socket to which the fixtures to be filled can be connected. 【0133】 It should be noted that the orifices 73, 74, 85, and 86 of this acceptance and support base 88 may have different diameters corresponding to the diameters of the exit orifices 12 and 17 of their respective compartments 11 and 16, in order to ensure the key function. 【0134】 The orifices 73, 74, 85, and 86 of this base 88 can be sealed, for example, by a screw-in plug 87. This plug 87 may come from one of the containers 71, 72, 81, and 82. 【0135】 In certain embodiments, at least one of the containers 71, 72, 81, and 82 may be a solution storage bag. 【0136】 Figures 10-11 show a stand 90 for simultaneously loading compartments of an apparatus for dispensing a first product and a second product, known as a dual-compartment apparatus, according to a fourth embodiment. 【0137】 The elements of stand 90 shown in Figures 10 and 11, which have the same reference numerals as those of stands 70 and 80 shown in Figures 7 to 9, represent the same object, which will not be described again below. 【0138】 The stand 90 shown in Figures 10 and 11 differs in essence from those shown in Figures 7 and 9 in that its receiving and support base 91 includes a support 92 for receiving fixtures 10, 50 for distributing a first product and at least one second product between their two uses. Furthermore, the duct 93 of the receiving and support base 91 is removable so that it can be replaced with a new duct at least partially when the fixture is configured to receive at least one new product.
