unit dose dispensing example

The invention has now been described in detail for the purposes of clarity and understanding. Various dispensing cabinets and carts have been developed to assist in the management of medications and other items. This direct measurement provides additional feedback as to the operation of dispensing mechanism 203. 29, a spring-loaded idler 2908 maintains tension on belt 2901, and takes up the unevenness of the travel of belt 2901 over square sprocket 2906. Other kinds of actuators and driving arrangements are possible. By using more sophisticated monitoring strategies, accidental dispensing of multiple items may be detected. A sprocket 2906 turns with drive shaft 2902 to drive belt 2901, providing positive relationship between the angular position of drive shaft 2902 and the travel of belt 2901. Computer 103 can also preferably detect the presence of a dispensing unit at any one of the bay positions, through the respective connector 302 or via a separate sensor. 8,126,590 to Vahlberg et al., issued on Feb. 28, 2012, U.S. Pat. Dispensing mechanism 3600 is similar in some ways to dispensing mechanism 204 described above, and may be especially useful in dispensing vials such vial 1301 shown in FIG. In addition, each dispensing unit can preferably also communicate to computer 103 the kind and quantity of items it contains and stands ready to dispense. When an item is dispensed through opening 604, it interrupts the light received by either or both of light receivers 707, and dispenser 701 can note that an item has in fact been dispensed. No. Dispensing mechanism 202 may be especially useful for dispensing small items such as individual medicine doses packaged in well-known “blister packs”, although dispensing mechanism 202 may be useful for dispensing may other kinds of items as well. No. In other embodiments, a dispensing mechanism in accordance with embodiments of the invention may not have the separable architecture of dispensing mechanism 2600, but may be a single unit including space for storing items to be dispense and including an actuator and other components for dispensing items. No. 11 is an oblique detail view of the upper portion of the cassette of FIG. Paddles 2904 circulate within chamber 2905 as belt 2901 moves. This direct measurement provides additional feedback as to the operation of dispensing mechanism 202. FIG. Vial 1301 may be used, for example, for storing fluids for loading into a hypodermic syringe for injection into a patient. Various parts of dispensing mechanism 202 collectively constitute a housing that defines an opening 604 at the bottom of dispensing mechanism 202, through which items are dispensed. The dispensers may be placed in a dispensing unit that includes a lockable restock drawer and a dispense drawer into which items are dispensed by the dispensing mechanisms. Syringe 2000a can accordingly drop through opening 2202 and into dispense drawer 107. Motor 1904 turns a cam 1905 in the direction shown, the function of which is explained in more detail below. 37. FIG. FIGS. In various embodiments, cassette 1802 may displace less than 25, less than 20, less than 15, or less than 10 cubic centimeters for each item stored in cassette 1802 at full capacity. In some embodiments, the dispensing mechanism further comprises a light emitter directed across the opening and one or more receivers that detect light from the light emitter reflected from a far wall of the opening, the light emitter and the one or more receivers positioned such that the light detected by at least one of the one or more receivers is interrupted by the passage of a vial dispensed through the opening. Other kinds of actuators and driving arrangements are possible. Some patients may only require a single unit, which is a very small amount and can be difficult to measure. For example, the passing of paddles, Dispensing Mechanism for Vials and Other Similarly-Shaped Items, In other embodiments, an actuator other than a motor may be used. For example, light emitter 1807 may be a light emitting diode, a laser such as a vertical cavity semiconductor emitting laser (VCSEL) or another kind of light source, and may emit visible light, infrared light, or light in other suitable wavelength bands or combinations of wavelength bands. That is, detection signal 6005 is high only when outputs 5902a-c exceed references 6002a-c, and output 5902b is below reference 6002d. A time limit may be imposed, such that if no dispensing is detected within the time limit with motor 1904 running, the motor may be shut off and an error message generated. Medications may be stored in individually lockable compartments within drawers such as drawers 102. In other embodiments, an actuator other than a motor may be used. While other dimensions may be used, example cassette 3602 is about 232 mm high, 72 mm wide, and 54 mm deep (displacing about 902 cubic centimeters), and can hold about 30 vials of the 2 ml size. For example, a solenoid or memory metal actuator may provide a reciprocating motion that is used to drive the driving gear within dispenser, A microprocessor, microcontroller, or similar controlling circuitry may reside within dispenser, As was discussed above, dispensing mechanism, Other arrangements are possible. 44A and 44B illustrate upper and lower views of a dispensing mechanism in accordance with other embodiments of the invention. Unit dose system means a system in which multiple drugs in unit dose packaging are dispensed in a single container, such as a medication drawer or bin, labeled only with patient name and location. The detection may be accomplished in any suitable way, for example periodic polling using antenna 1805, a contact sensor (not shown) that can detect the presence of cassette 1802 electromechanically, or by another technique. The dispensing mechanisms include multiple sensing technologies for tracking and inventory of items and for accurate sensing of items as they are dispensed. While cassette 3602 is shown as having three vertical channels 3701, other numbers of channels may be used. Output 5902b is fed to two comparators 6001b and 6001d. FIG. By using more sophisticated monitoring strategies, accidental dispensing of multiple items may be detected. 4A, showing a back panel 501 of restock drawer 106. 52, the travel of light from emitter 5201 to surface 5203 and back to sensor 5204 is unobstructed, so that sensor 5204 will produce a signal indicating that it is receiving light. slotted gear 1701 drives slotted gears 1702 and 1703. Dispensing unit 105 may include features to facilitate the use of dispense drawer 107 as a work surface. 40 shows a rear orthogonal view of a lower portion of cassette 3602, and illustrates the operation of a brake 4001. A gear 703 engages a driving gear (not easily visible in FIG. While embodiments of the invention are described in the context of stationary cabinet. 4. 42 and 43 illustrate a number of ties installed in the openings shown in FIG.

Dispenser PCBA 2303 also includes various power and communication circuitry, driver circuitry for a motor, a wireless communication interface and antenna, various other sensors, and other components, many of which may be described above in relation to dispensers 701, 1201, and 1801. Guide 2102 is force upward by its interaction with slide 2204, to jostle any remaining syringes within cassette 1802, facilitating their future dispensing. 59, six light receivers in the form of phototransistors 5901 produce outputs 5902a-5902f indicating the intensity of light being received by the respective phototransistors 5901. 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. FIG. When the downward vertical orientation is reached, vial 1705 will be free to drop through opening 1206 into dispense drawer 107. In some embodiments, the connector and actuator are comprised in a dispenser, and the belt, paddles, and housing are comprised in a cassette, and the dispensing mechanism further comprises a driving gear in the dispenser turned by the actuator and a driven gear in the cassette, the driven gear being driven by the actuator and causing the belt to be driven. Sensor 5204 produces a signal indicating the intensity of light falling on it. If any of ties 3501 is missing or damaged, diversion may be suspected. Particular paddles 2904a, 2904b, 2904c, and 2904d have been moved from their assembled positions, for clarity of explanation. In the claims appended hereto, the term “a” or “an” is intended to mean “one or more.” The term “comprise” and variations thereof such as “comprises” and “ comprising,” when preceding the recitation of a step or an element, are intended to mean that the addition of further steps or elements is optional and not excluded. In operation, light from the light emitter reflects from reflective surface 1205 (visible in FIG. 6A and 6B. For example, in various embodiments, cassette 2702 may displace, less than 30, less than 25, less than 20, less than 15, or less than 10 cubic centimeters for each item stored in cassette 2702 at full capacity. Preferably, any active parts of the sensing system reside in dispenser 1201, so that cassette 1202 does not include active electrical components. When one of the receivers reaches its upward vertical orientation and at least one vial is present in the corresponding vertical channel of cassette 3602 (not shown), the vial is free to drop into the respective receiver 3704. 22A. Preferably, as will be discussed in more detail below, cassette 702 does not contain any active electrical components.
