For example, as shown in FIGS. This arrangement allows the adjacent pairs of paddles defining compartments for holding items to be dispensed to remain closer together as they traverse the top of cassette 2702 than if sprocket 2906 were round. Each connector 301 connects with a mating connector attached to wiring within a rail 201 positioned at the respective hanger 205, supplying power and signals coming from other systems within cabinet 100. The invention has now been described in detail for the purposes of clarity and understanding. FIGS. FIG. The system further comprises a dispensing mechanism that contains one or more items to be dispensed, and is configured to cause the items to be dispensed one at a time through the opening. A reflective optical sensor may be provided within dispenser 701 that shines light (for example infrared light) onto the driving gear and can detect whether a return reflection is received. It is to be understood that any workable combination of the elements and features disclosed herein is also considered to be disclosed. Motor 2801 (and thus belt 2901) may be driven in either direction. If detection signal 6005 goes low at such a time, it may be suspected that a diversion attempt is underway, with a finger or tool being inserted into the dispensing mechanism from below. As you might suspect, engineers … 22A-22C illustrate a cutaway view of portions of dispenser 1801 and cassette 1802 and their operation to dispense a syringe. FIG. 54 shows a light curtain having a black surface 5401, with no item being dispensed. For example, the driven gear within cassette 3602 may have holes around its main portion, so that the remaining material between the holes functions as broad spokes. FIG. Privacy Policy For example, logic signals from a supervisory controller elsewhere within restock drawer 106 may operate dispenser 701. 29 shows an orthogonal view of a cassette portion of the dispensing mechanism of FIGS. Detection output 6005 will normally be high, but will go low when any one or any number of comparators 6001a-d gives a low signal. The passing of the reflective sticker, as detected by the sensor, verifies that slide 2204 has actually moved. 25 illustrates a more detailed electrical block diagram of a dispenser PCBA 2303, in accordance with embodiments of the invention. 5,805,456, issued on Sep. 8, 1998 to Higham et al, U.S. Pat. FIG. In other embodiments, light emitter 1807 and receivers 1808 may be on opposite sides of opening 1804, so that receivers 1808 receive light directly from light emitter 1807 until the light is interrupted by the dispensing of an item. However, the following 17 illustrates a front view of the lower portion of dispenser 1201, showing additional details of its operation. If no light interruption is detected despite a command to dispense an item, computer 103 may assume that a misfeed or other problem has occurred, or that cassette 702 is empty. FIG. A light emitter 5201 emits light through space 5202 toward a surface 5203. A processor or other circuitry within dispenser 2701 can interpret this signal to verify the motion of the driving gear. FIG. Syringe 2000a is in position to be dispensed, while cassette 4402 contains additional syringes such as syringe 2000b. The dispensing mechanisms include multiple sensing technologies for tracking and inventory of items and for accurate sensing of items as they are dispensed. 5,745,366, issued on Apr. FIG. Preferably, cassette 1202 does not contain any active electrical components. A microprocessor, microcontroller, or similar controlling circuitry may reside within dispenser 2701, and may operate the various active components and sensors of dispenser 2701 in response to high-level commands from a supervisory controller elsewhere within restock drawer 106, or from computer 103. Motor 801 (and thus belt 1001) may be driven in either direction. Doses are dispensed for an individual patient on a 24-hour supply basis and pharmacy services necessarily run a 24-hour, seven days a week operation to facilitate this. 16, showing additional details of its operation. This kind of dispenser, although widely and successfully used, is somewhat limited in the shapes and sizes of items that could be dispensed, as the items must be compatible with the pitch and size of the coil.

Sprocket 2906 is non-circular. Dispensing mechanism 204 may be removably secured to one of rails 201 using a snap mechanism, one or more screws, or by another method. If any of ties 5001 is missing or damaged, diversion may be suspected. Preferably, any active parts of the sensing system reside in dispenser 701, so that cassette 702 does not include active electrical components. No. While all medication doses leave very little room for error, some require such precision dosing that even the slightest error can have serious consequences. Other sizes of dispensers, for example triple and quadruple widths are also possible. Some light may scatter from the surface of vial 5301, but little will reach sensor 5204, and the signal produced by sensor 5204 in this state indicates that little or no light is reaching sensor 5204. Other similarly-shaped items may also be dispensed by dispensing mechanism 204. The dispensing mechanism further comprises a housing defining opening at the bottom of the dispensing mechanism. The dispensing mechanism further comprises a plurality of paddles integrally formed with the links of the belt for receiving between pairs of the paddles items to be dispensed, the paddles extending from the belt. Motor 1601 may be, for example, a stepper motor or a simple DC or AC motor, operated in the manner described above in relation to dispensing mechanism 202. Light emitter 5201 may be, for example, an infrared light emitting diode (LED) emitting light at a wavelength of about 940 nm, or may be another kind of light emitter. For example, a syringe 2000 configured to hold 1 ml of liquid may have an overall length of about 115 mm, while a syringe 2000 configured to hold 2 ml of liquid may have an overall length of about 148 mm. In cassette 3602, three vertical channels 3701 are present, and vials 1301 are 2 ml vials, having a diameter of about 15 mm, and a height of about 35.5 mm. 14/634,063, filed Feb. 27, 2015 and titled “Unit Dose Dispensing Systems and Methods”, the entire disclosures of which are hereby incorporated by reference herein for all purposes.
