As shown in
According to some embodiments, dispensing head 500 includes a receptacle carrier 504 for coupling one or more medication receptacles such as 108 to head 500.
According to some embodiments, dispensing head 500 is moveable by one or more motors. In some embodiments, motor 506 moves head 500 in horizontal direction X. In some embodiments, motor 508 moves head 500 in vertical direction Y. In some embodiments, one of motors 506 or 508 moves head 500 in horizontal direction Z. In some embodiments, one or more of motors 506/508 are actuated by control circuitry 510. In some embodiments, control circuitry 510 is coupled to dispensing head 500. In some embodiments, for example as shown in
According to some embodiments, the dispensing system includes a suction system 520 connected to head 500, for attaching medication dosage to an extraction probe as described elsewhere herein.

In some embodiments, suction system 520 includes a suction controller 524 connected to suction pump 520 for controlling the suction provided to gripper 512. In some embodiments, suction controller 524 is disposed within head 500. In some embodiments, determining the required suction power is according to the characteristic and parameters of the medication dosage (e.g. type, shape, weight, etc.). In some embodiments, suction system 520 includes a suction sensor for measuring suction power provided to gripper 512. In some embodiments, the suction sensor is connected to gripper 512. In some embodiments suction power is controlled by one or more suction valves coupled to dispensing head 500.
According to some embodiments, control circuitry 510 controls the movement speed of head 500 according to the characteristic and parameters of the medication dosage (e.g. type, shape, weight, etc.). A potential advantage of controlling the speed of head 500 and/or suction power is reducing loosing of a medication dosage coupled to dispensing head 500 after being extracted out of the container. Another potential advantage of controlling the suction power is reducing of failures in extracting medication dosage by the dispensing head 500.
According to some embodiments, gripper 512 is linearly moveable in respect to platform 502. In some embodiments, gripper 512 is configured to grab a probe inserted in a medication container by approximating gripper 512 to the probe for grabbing the probe away of the container by a linear motion. In some embodiments, gripper 512 is configured to return the probe to the container by a linear motion towards of the container. In some embodiments, gripper 512 is actuated to move linearly by a linear system 516 coupled to platform 502. In some embodiments, moving gripper 512 in linear motion is without moving platform 502 in respect to the medications panel.
According to some embodiments, a picked probe is rotated by gripper 512 to be positioned above a medication receptacle for dispensing extracted medication dosage into the medication receptacle. In some embodiments, gripper 512 is rotationally coupled to platform 502. In some embodiments, rotating of gripper 512 is by rotation system 514 coupled to platform 502. In some embodiments, head 500 is configured to move the gripper 512 in a rotational motion without moving platform 502 in respect to the medication panel. In some embodiments, there is no linear movement of gripper 512 in a horizontal direction away of the container between the extracting and the dispensing of medication dosage. In some embodiments, the rotation is in the range of 10 to 85 deg. In some embodiments, the rotation is in the range of 25 to 75 deg. In some embodiments, the rotation is in the range of 30 to 60 deg.
In some embodiments, control circuitry 510 outputs positioning signals to actuators 514/516 to move gripper 512 to position the opening of the receptacle in a horizontal distance of less than 10 cm from the medication dosage. In some embodiments, control circuitry 510 outputs positioning signals between or during outputting approximating signals and outputting dosage manipulation signals.
A potential advantage in limiting the motion of the probe by head 500 is that the time the medication container is left open when probe is out of the container minimized. In some embodiments, the time between grabbing of the probe out of the container by gripper 512 and dispensing the medication dosage in the medication receptacle is shorter than 10 sec. In some embodiments, the time between grabbing of the probe out of the container by gripper 512 and dispensing the medication dosage in the medication receptacle is shorter than 4 sec. In some embodiments, the time between grabbing of the probe out of the container by gripper 512 and dispensing the medication dosage in the medication receptacle is shorter than 1 sec. Another potential advantage is reducing accidental loosing of the medication dosage from the probe prior to dispensing the medication dosage inside the medication receptacle.
According to some embodiments, head 500 is configured to communicate with the medication container via a chip or RFID tag mounted at the container, or by using barcode at the container. In some embodiments, the RFID/chip is used to transmit operational parameters of the container. Some examples of information that can be communicated via RFID/chip are: identifying medication within container, counting medication dosages, receiving status details, dispensing status, etc. In some embodiments, head 500 is updating information encoded on the container. For example: updating medication dosage remaining within container after extracting dosage by head. In some embodiments, head 500 has a RFID/tag reader and/or encoder 524. In some embodiments, read/encoder 526 is coupled to platform 502. In some embodiments, read/encoder 526 is coupled to gripper 512.
According to some embodiments, reader/encoder is movable to enable approximating and detracting to/from the medication container. In some embodiments, read/encoder 526 is configured to move together with gripper 512. For example, for approximating RFID tag/Chip of container, while picking a probe by gripper 512. In some embodiments, reader/encoder 526 is configured to move independently of gripper 512. In some embodiments, reader/encoder 526 is configured to rotate with gripper 512, and to move linearly independently of gripper 512. A potential advantage in moving reader/encoder 526 is that the head 500 is communicating with medication containers, without further moving the head 500. This can help minimizing travel for the head 500 and reducing dispensing process time. A communication of head 500 with container can also help avoiding an initiation of medication extraction in case reader 526 detects some unexpected input from a chip of the container, e.g. out of medication. Such exception can proceed to moving head 500 automatically to another container, without proceeding a faulty dispensing process. This can increase usability, by reducing fault handling by an operator. This can also reduce idling of the dispensing system.

1046 optionally checking of container has pills. In some embodiments, checking 1046 include counting the number of pills.
In some embodiments, when container is empty of pills, the dispensing system is configured to proceed to alerting and ejecting envelope 1048. In some embodiments, when container is empty, the dispensing system is configured to locate an alternate location having the medication.
In some embodiments, alert is sent to another system in communication with the dispensing system. In some embodiments, an action depends on a response to the alert. In some embodiments, ejecting is by/to a user, which receives details about the alert. In some embodiments, envelope is marked to identify exception.
1050 Filling container with medication.
According to some embodiments, the medication panel have redundancy of medications prepared in more than one medication assemblies. In some embodiments, redundancy reduced dispensing failures by moving the head, having an envelope, to another container without a critical alert, discarding the envelope, interruption, system idling, and/or requiring operator attention.
In some embodiments, after filling 1050, the dispensing head proceed to repeat dispensing steps, by 1038 Grabbing probe from medication container. In some embodiments, there is an optional step of closing envelope prior to repeating dispensing steps. In some embodiments, the envelope is closed between 80-98% of the time between moving 1030 and crimping 1058. In some embodiments, the envelope is closed between 85-95% of the time between moving 1030 and crimping 1058. In some embodiments, the envelope is closed between 90-93% of the time between moving 1030 and crimping 1058. In some embodiments, envelope is open only between checking 1040 and placing pill 1044. Closing the envelope between operations can potentially reduce contamination of medication disposed inside the envelope.
According to some embodiments, described elsewhere herein, the content of the containers assemblies is known prior to having the dispensing head approximating a container.
1052 Returning probe and write to RFID.
1054 Checking if dispensed pill is the last pill required to be dispensed in envelope.
If envelope should receive additional pills, the head will proceed to repeat from step 1036.
If dispensed the last pill required to be placed in envelope, the envelope can be moved 1056 to a crimping module and crimping 1058.
1060 Checking PRN.
1062 Ejecting envelope when checking PRN 1060 is positive.
According to some embodiments, checking PRN 1060 is positive when medication is required to be submit to the patient immediately (e.g. when patient is in pain or not yet in database or just enrolled in facility). In some embodiments, ejecting 1062 is to a nurse in a single manner and not through the medications tote.
1064 Proceeding to position envelope in medication tote. In some embodiments, proceeding 1064 is on scheduled medication runs, so than checking PRN 1060 is negative.
One or more of the checking steps, mention above can be optional. The checking steps can potentially save redundant movements of the dispensing head, for example, when medication is not ready in container or envelope is not in a proper state, save extraction of medication when envelope is not ready, and save movement of head having a medication when envelope is not open.
According to some embodiments, a detachable probe P is coupled to the medication containers (such as 402) for picking medication dosage. In some embodiments, extracting medication dosage is by grabbing probe P out of the medication container by the dispensing gripper (such as 106608 described elsewhere herein).
