Definitions

  • This invention relates to the product dispensing art and, more particularly, to a device and method for reliably dispensing controlled amounts of product such as medication.
  • Effective drug treatment by physicians often depends upon patient compliance in following the prescribed regimen of drug dosage.
  • One apt example of this is the treatment of schizophrenic patients with tranquilizers and antidepressants such as lithium and librium.
  • the common experience has been that, as a patient begins to feel better, he stops taking the medication, either intentionally or by forgetting. As the body fully metabolizes the medication, symptoms reappear. The patient sometimes then attempts to take excessive medication, thereby causing adverse psychological consequences.
  • the invention permits units of a product, such as medication, stored with random orientation to be dispensed one at a time or a predetermined number at a time at prescribed time intervals.
  • One aspect of the invention is a product dispenser including a storage station for storing items of a product to be dispensed, an exit from the dispenser, and an intermediate station inaccessible from the exit except during delivery of an item to the exit.
  • a transport member carries one item or a predetermined number of items of the product at a time from the storage station to the intermediate station.
  • an item or the predetermined number of items at the intermediate station are delivered to the exit through a gate movable between an open position and a closed position.
  • a perceptual indication of the presence of an item or the predetermined number of items at the intermediate station is given by a window in the dispenser or other means so the user may know when to open the gate.
  • a latch enables and disables the gate responsive to a timer at prescribed time intervals and another latch disables the transport member when the gate is open so delivery of the prescribed number of items to the exit may not be exceeded.
  • Provision of the intermediate station permits items of the product to be stored in random orientation at the storage station. Since the transport member can only carry one item or a predetermined number of items at a time, an excessive number of items cannot reach the intermediate station before the gate is opened. If too few items or no items reach the intermediate station, the user can continue to operate the transport member until the prescribed number of items are there present for delivery to the exit before opening the gate.
  • Another aspect of the invention is a method for dispensing medication in pill form at prescribed time intervals comprising the steps of storing the pills in a chamber with random orientation, ascertaining the presence or absence of a pill at an inaccessible position, attempting to carry the pills singly from the chamber to the inaccessible position until one pill reaches the inaccessible position and, after ascertaining the presence of a pill at the inaccessible position, delivering such pill to the exit at a prescribed time interval.
  • a product dispenser comprises a base 10, a rotatable wheel-shaped transport member 12, and a translatable gate 14.
  • base 10 is basically rectangular in shape. It has a horizontal top surface 16 from which a vertical cap mounting wall 18 perpendicularly extends.
  • a window 20 is formed of a transparent material at the front of base 10 adjacent to top surface 16.
  • a semi-circular, horizontally extending slot 24 is formed in the front of base 10 under window 20.
  • An opening 26 surrounded by an upwardly facing recess 28 extends from the top of base 10 to slot 24.
  • a rectangular groove 32 is formed in the bottom of base 10 below slot 24 from front to rear. Groove 32 has a step 30 near the front of base 10, which makes the front of groove 32 open into slot 24 and the back of groove 32 shallower than the front.
  • a portion 22 of base 10 separates the back of groove 32 from the portion of slot 24 below opening 26.
  • a cylindrical product container 34 is mounted in recess 28 with its open top facing down. Randomly oriented items 36 such as pills or capsules of medication having the same size and shape are stored in container 34.
  • a cap 36 has a circular recess 38 for receiving the upturned bottom of container 34.
  • Cap 36 is secured on the end of mounting wall 18 by fasteners 40 so as to clamp container 34 to base 10. If desired, a lock could be provided to prevent unauthorized removal of container 34.
  • Opening 26 is substantially larger than items 36 so as to permit unobstructed passage thereof to bore 46.
  • Transport member 12 fits in slot 24, where it is guided for free rotation by the circular side wall of slot 24, which extends substantially more than half way around transport member 12. A portion of transport member 12 protrudes out of slot 24 in front of base 10 to permit its rotation by the user's thumb.
  • Transport member 12 has an off-center axial bore 46, which forms a cavity therein. Bore 46 is sufficiently large to hold one, and only one, of items 36, i.e., it is not large enough under any circumstances to hold two or more items thereof. Bore 46 is so positioned in transport member 12 that as transport member 12 rotates, bore 46 passes under opening 26 in base 10, thereby permitting one of items 36 to enter bore 46 by force of gravity. Slight reciprocating motion of transport 12 may be necessary to assist alignment of an item with bore 46.
  • transport member 12 has a radial slot 48. Bore 46 is suitable for round items. Generally, the shape. of the opening in transport member 12 would match that of the item.
  • Gate 14 comprises an elongated slide portion 50 having a rectangular cross section fitting in groove 32 of base 10.
  • Slide portion 50 has a central portion that translates back and forth in groove 32. The height of this central portion is the same as the depth of the back of groove 32, so that it is flush with the bottom surface of base 10.
  • Gate 14 is held in groove 32 by bars 52 or other means attached to the bottom surface of base 10.
  • Slide portion 50 has a stepped stop portion 54 at its front end and a ramped cam portion 56 at its rear end. Near stop portion 54, a rectangular opening 58 extends through slide portion 50 from end-to-end parallel to bore 46. The height of stop portion 54 is the same as the depth of the front of groove 32, so that it is flush with the bottom surface of base 10.
  • slide portion 50 has a hole 60.
  • a peg 62 extends upwardly from the top surface of slide portion 50 between bore 58 and hole 60.
  • Peg 62 is sufficiently small to fit in slot 48.
  • Peg 62 rides in a slot 64 formed in base 10 along part of the length of groove 32. Slot 64 is so positioned to extend forward and rearward of slot 24 as shown in FIG. 2 and is sufficiently deep to extend vertically from groove 32 to approximately the middle of slot 24 so as to be able to carry peg 62 into and out of engagement with slot 48.
  • Gate-14 also has a box-shaped exit portion 66 extending downwardly and forwardly of slide portion 50 so as to lie under bore 58.
  • Gate 14 is translatable between a closed position in which stop 54 abuts step 30 and an open position in which peg 62 abuts the front of slot 62.
  • opening 58 lies under portion 22 of base 10 as shown in FIG. 1.
  • none of items 36 can pass through opening 58 to exit portion 66.
  • opening 58 lies in front of step 30 in the path of bore 46 so that bore 46 and opening 58 are alignable with each other.
  • gate 14 cannot be opened unless slot 48 is aligned with peg 62, which requires bore 46 to be in front of base 10 as shown in FIG. 2.
  • a solenoid actuator 68 is attached to the back of base 10 by means not shown.
  • Actuator 68 has a retractable, i.e., axially movable, pin 70 which is aligned with hole 60 when gate 14 is in its closed position.
  • Pin 70 is biased downwardly by a spring not shown so it is normally inserted in hole 60.
  • actuator 68 is energized, pin 70 is retracted from hole 60 by the solenoid.
  • Normally open microswitches Sl and S2 are arranged in the path of gate 14 so as to be closed successively, first switch Sl and then switch S2, by cam portion 56, as gate 14 moves away from its closed position toward its open position.
  • Hole 60 is sufficiently large relative to pin 70 to permit movement of gate 14 toward its open position sufficiently for cam portion 58 to actuate switch Sl with pin 70 in hole 60.
  • gate 14 is normally closed and pin 70 is inserted in hole 60 so that gate 14 is latched and cannot be translated to its open position.
  • actuator 68 is not energized so pin 70 continues to latch gate 14 in its closed position.
  • an alarm is given to the user of the dispenser that one item of the product may be taken therefron.
  • actuator 68 is energized to retract pin 70, which unlatches gate 14 and permits the user to open gate 14.
  • cam portion 56 passes switch S2 while opening gate 14, actuator 68 is de-energized and the circuit is reset.
  • Transport member 12 Prior to opening gate 14, the user rotates transport member 12 with his finger to swing bore 46 from a position under container 34 to a position under window 20, which is called herein the "intermediate station.”
  • Transport member 12 normally carries with it one of items 36 from container 34 to the intermediate station. The user can ascertain the presence of one of items 36 at the intermediate station by observation through window 20. If transport member 12 fails to carry one of items 36 with it to the intermediate station, the user can try again until he is successful in carrying one of units 36 to the intermediate station, before translating gate 14 to its open position. If the user fails to carry an item to the intermediate station before opening gate 14, he loses the opportunity to recover an item until the next prescribed time interval has elapsed because gate 14 can only be opened once at each time interval.
  • the user When one of items 36 is at the intermediate station, the user opens gate 14, causing the item at the intermediate station to fall through bore 58 by force of gravity onto exit portion 66, where the user can gain access to such item. While gate 14 is open, transport member 12 is latched in place at the intermediate station by the presence of peg 62 in slot 48 so that the user cannot carry more items to bore 58. Peg 62 prevents the opening of gate 14 unless transport member 12 is at the intermediate station. When the user closes gate 14 again, pin 70 is urged by the actuator spring into hole 60, thereby latching gate 14 in its closed position once again until the next time interval has elapsed. In summary, the user can retrieve one, and only one, of units 36 at a time and only at prescribed time intervals, although the items are stored with random orientation in their container.
  • FIG. 5 shows a preferred arrangement for electrically controlling actuator 68, the solenoid of which is represented as a coil 72.
  • the output of a digital clock 74 is coupled by a decoder 76 to one set of inputs of each of coincidence gates 78 and 80.
  • the positive terminal of a battery 82 is coupled by a plurality of individually actuatable timing switches 84 to the other set of inputs of coincidence gate 78.
  • the positive terminal of battery 82 is coupled by a plurality of individually actuatable timing switches 8 6 to the other set of inputs of coincidence gate 80.
  • the states of timing switches 84 determine the prescribed time intervals at which items may be recovered from the dispenser and the states of timing switches 86 determine the time window after the lapse of each interval during which the items may be recovered from the dispenser.
  • R-S flip-flops (F F ) 88 and 90 each have an S input, an R input, a Q output, and a Q output.
  • the output of coincidence gate 78 is connected to the S input of flip-flop 88.
  • the output of an AND gate 92 is connected to the R input of flip-flop 88.
  • the output of coincidence gate 78 is connected to one input of AND gate 92.
  • the positive terminal of battery 82 is coupled through a normally open, manually operated switch 94 to the other input of AND gate 92.
  • the Q output of flip-flop 88 is connected to the S input of flip-flop 90 and to a beep oscillator 96. Beep oscillator 96 drives a loud speaker 98.
  • the output of an OR gate 100 is connected to the R input of flip-flop 90.
  • the output of coincidence gate 80 is connected to one input of OR gate 100.
  • the positive terminal of battery 82 is coupled through switch S 2 to the other input of OR gate 100.
  • the Q output of flip-flop 90 and the Q output of flip-flop 88 are connected to the inputs of an AND gate 102.
  • Switch 51 and solenoid coil 72 of actuator 68 are connected in series between the output of AND gate 102 and the negative terminal of battery 82, which is grounded.
  • flip-flop 88 which serves as an actuating flip-flop
  • flip-flop 90 serves as a control flip-flop.
  • speaker 98 produces an audible alarm, which alerts the user.
  • the user then closes switch 94 to acknowledge his awareness of the availability of an item, which resets flip-flop 88.
  • the output of AND gate 102 is then energized because both its inputs are energized. This enables gate 14.
  • solenoid coil 72 is energized by the output of AND gate 102.
  • flip-flop 90 is reset, thereby de-energizing solenoid coil 72 and disabling gate 14.
  • flip-flop 90 is reset by coincidence gate 80 so that thereafter an item cannot be recovered until the elapse of another time interval, at which time flip-flop 88 is again set by coincidence gate 78.
  • switches 84 would be set so coincidence gate 78 produces indications at 8 a.m., 4 p.m., and midnight and timing switches 86 would be set so coincidence gate 80 produces indications at 9 a.m., 5 p.m., and 1 a.m. '
  • the logic of the use of the dispenser calls for gate 14 to be opened upon coincidence of the following conditions: first, an item at the intermediate station and second, the elapse of the prescribed time interval.
  • the first condition is determined by the user.
  • it could be determined by a sensor such as a photocell, in which case an AND gate could be added to set flip-flop 88. (The sensor and coincidence gate 78 would be connected to its inputs.)
  • bore 46 could be dimensioned-relative to the size of items 36 to carry to the intermediate station 2, 3, 4, or other predetermined number of items at a time rather than one; this could be carried to the extreme, where the described device is used to dispense product in powder form.
  • window 20 instead of window 20, other means such as a sensor and an alarm could be used to provide a perceptual indication of the presence of an item at the intermediate station.
  • transport member 12 could be translatable instead of rotatable or gate 14 could be rotatable instead of translatable.
  • gate 14 could be automatically controlled to open responsive to coincidence gate 78 if desired and/or transport member 12 could be automatically controlled responsive to a sensor to keep operating, i.e., rotating, until an item is at the intermediate station.
