Definitions

  • the present invention relates to a vending machine medicines in the form of pills, capsules or the like, intended to deliver at predetermined times, one or more drugs previously introduced into the dispenser.
  • Such a dispenser essentially comprises a base fixed on which is mounted a reservoir, or charger, of drugs rotary.
  • the tank usually consists of one element cylindrical in the thickness of which are provided, in the vicinity from the periphery, open accommodation for storing doses of drugs to distribute.
  • the base has, in its face upper window next to the tank, a window of corresponding size approximately the size of the opening of a housing of the tank and communicating by a fall with a return access medication, usually on a side of the base.
  • the tank is driven in regular rotation by relative to the plinth so that all the tank housings pass successively in front of the base window to deliver the drugs they contain.
  • the tank is loaded from its upper face by introducing into each housing, the medication (s) to be dispensed at the corresponding time.
  • Distributors of such drugs are generally used at home by patients whose treatment requires permanent medication at intervals regular. Most often, these are weekly distributors whose tank has twenty-one housing representing morning, midday, and evening catches for each day of the week. These distributors are, the most often associated with an audible alarm device triggered each dispensing of drugs by the distributor.
  • Vending machines for medicines of this type type are described, for example, in documents FR-A-2 718 636 and US-A-4,674,651.
  • a given reservoir that is to say comprising a number of housing given
  • the tank is associated with means of hourly programming accessible by the user who cooperate with the base to trigger the audible alarm signal when each programmed take.
  • the tank and the base are made more complex, we must manufacture, to each type of tank (monthly, weekly, daily or other), a dedicated base.
  • a first solution would be to to rotate the tank, not regularly, but suddenly with each new take.
  • a such a solution would make the distributor's drive system much more complex compared to a training system in regular rotation.
  • US-A-4,573,606 describes another type of dispenser of drugs in which the cylindrical member constituting the tank is held vertically, that is to say that the cylinder axis is horizontal and not vertical as in the distributors described above.
  • the tank defines open housing on the outskirts for distribution and opposite before for filling. If she avoids premature delivery drugs, such a vertical arrangement of the dispenser is impractical, especially for filling with the face of the tank.
  • the base provided by document US-A-4,573,606 includes a cylindrical ring for receiving the reservoir provided, in the bottom of its periphery, an opening constituting a window of distribution.
  • the distribution window is associated with a shutter controlled by the rotation of a bottom plate associated with the tank and provided with trigger notches. AT opening the shutter, the drugs fall into a removable cup placed directly above the shutter.
  • the presence of the bucket increases the size, in particular in height, of the dispenser. In in addition, an additional height must be available under the bucket to allow the delivery detector to operate of drugs included in this document.
  • the present invention aims to propose a new distributor pills, capsules or the like which is particularly simple to set up and operate.
  • the present invention also aims to provide a distributor medicines in which, at least for manufacturing, the base can be independent of the periodicity of catches defined by the tank.
  • the present invention therefore also aims to provide a distributor in which security linked to distribution does not not at the expense of energy consumption.
  • the invention aims to provide a distributor in which actuation of a shutter shutter of a window distribution requires very little energy.
  • the closure element is associated with an axis of rotation housed in the base, and comprises a first plate constituting a flap suitable for closing the distribution window and a second plate approximately perpendicular to the first, the axis being placed at the intersection between the two plates.
  • the opening of the shutter is caused at positions of the tank relative to the base, the element being actuated by a cam capable of cooperating with notches on the underside of the tank.
  • the plates are dimensioned so that the closure element is, when the cam is in a notch, in unstable equilibrium in its rotational position.
  • a weak weight preferably around 0.3 gram to match the minimum weight of a medication to be dispensed, based on the first plate is enough to cause the flap to tip over an open position.
  • the tank is associated with a cover provided with several elements housing coverage, each element being associated with at least one housing and being connected, by a hinge, to a central portion of the cover.
  • the tank has two concentric rings connected by housing definition walls, a first ring of smaller diameter being polygonal.
  • the number of sides of the polygon defining the first crown of the tank corresponds to the number of cover elements of the lid.
  • the base contains a motor for rotating an element transmission associated with the base, the transmission element being adapted to be linked in rotation to a drive element of the tank, housed therein.
  • the dispenser consists of stackable and assembled elements axially by means of a rectilinear element.
  • FIG. 1 shows, in perspective and very schematic, an embodiment of a drug dispenser in the form of pills, capsules or the like, according to the present invention.

  • the tube 96 is provided at a point on its external periphery with a polarizing 97 intended to cooperate in opposite form with a groove vertical 102 of orifice 101 to make element 9 and the pinion 10 integral in rotation.
  • clutch element 9 allows rotation manual movement of tank 4 clockwise watch to set the distributor "on time” when setting it up service by placing the housing 41 corresponding to the current outlet opposite opening 21.
  • the pinion 10 is preferably a crown pinion 105 in the internal surface of which teeth are formed 103 intended to cooperate with the teeth 104 of the drive wheel 100 ( Figure 2A).
  • the number of teeth 103 on the inner periphery crown 105 is adapted according to the number of teeth 104 of the driving wheel 100 and the speed of the motor 13, so that a sprocket revolution 10 corresponds to the desired exemption cycle for the distributor. If necessary, other gears are provided between a shaft (not shown) of the motor 113 and the wheel 100.
  • a clutch element may be provided in direct engagement with an axis of a gear housed in the base 2 or link the tank 4 at this axis.
  • a removable transmission pinion (10) between the base 2 and the tank 4 is that this minimizes the number of rooms dedicated to different versions of the dispenser.
  • an element 11 including a tubular portion 110 is successively engaged in the orifices 85 of the cover 8, 47 of the reservoir 4, 95 of the clutch element 9, 101 of the pinion gear 10, 26 of the base 2, and 35 of the base 3.
  • the element 11 comprises, at a first upper end, a button 111 of handling.
  • a second end 112 of the element 11 is suitable for cooperating with a nut 12 (FIG. 12) for locking the assembly carried out.
  • the portion 110 is split longitudinally (113) in the vicinity of the end 112 to present an elasticity allowing its engagement then its blocking in nut 12.
  • locking the end 112 takes place directly in the projection 34 of the base 2.
  • the upper wall 38 of the projection 34 includes radial lights 39 giving it elasticity during insertion of element 11.
  • spacers different constituent elements can be used to adapt the stack. These spacers will preferably be made in one piece with one of the elements that they are supposed to keep away from another element. Of such spacers assist in guiding the element 11 during distributor assembly.
  • the setting times are programmed by the mechanical constitution of the tank and not by programming electric based on a clock.
  • Distributor structure is considerably simplified. The case if applicable, the distributor is associated with a watch, but for its alarm function to remind the patient of the hours of taken and this watch is independent of the movement of the tank 4.
  • An advantage of the present invention is that the dispenser of drugs is particularly simple in constitution and comprises, with the exception of the motor 13, exclusively elements mechanical.
  • Another advantage of the present invention is that, at except engine 13, all components of the distributor can be obtained by plastic molding.
  • Another advantage of the present invention is that the constitution of the reservoir 4 makes it possible to postpone, during rotation, friction between the tank 4 and the base 2 on minimum surfaces (the ends of the crowns 43 and 42). That contributes to optimizing the energy required for operation, as well as the overall horizontal position of the distributor which optimizes the distribution of forces on the clutch element 9.
  • the reservoir 4 is made of polyamide or acetone-buthyl-styrene (ABS), and the base 2 is made of polypropylene or polyethylene.
  • ABS acetone-buthyl-styrene
  • the base 2 is made of polypropylene or polyethylene.
  • the cover 8 is made of polypropylene or polyethylene which allows the realization, in the mass, hinges 80 of elements 82.
  • An advantage of the present invention is that it is particularly suitable for mass production of elements components of the distributor by minimizing the number of elements customized according to version (frequency of exemption cycles) carried out. Indeed, only the gear pinion 10 conditions the duration of a cycle of rotation of the reservoir 4 and only the constitution of the reservoir 4 (in particular, the number and the position of the recesses 56 of the crown 42) conditions the moments of dispensing medication.
  • the base 3, the base 2, element 9, assembly element 11, 12 and, where appropriate, also the cover 8, can be undifferentiated for several distributor versions.
  • the present invention is capable of various variants and modifications which will appear to the man of art.
  • the respective dimensions of the different constituent elements of the dispenser according to the invention may be adapted according, for example, to the types of medication to be delivered and / or depending on the number of catches stored in the tank.
  • other forms than those indicated in the description which precedes by way of example, could be provided, provided to respect the functionalities described.
