The present invention, in some embodiments thereof, relates to a medication dispensing system and, more particularly, but not exclusively, to extracting medication out of medication containers and dispensing medication within medication receptacles.
Overview
A broad aspect of some embodiments of the invention relates to an arrangement of assemblies within a medication dispensing system to affect operational parameters. Some examples of the operational parameters include: increasing dispensing rate, controlling vertical size, reducing horizontal size, increasing number of medication types available for dispensing, reducing mean time to repair, reducing mean time to prepare system, reducing mean time system accessed by, and reducing idle time.
According to some embodiments, the medication dispensing system has a gripping assembly that picks a medication dosage out of medication container assemblies arranged vertically on one or more medication panels, and dispenses the medication dosage into a medication receptacle. In some embodiments, the gripping assembly moves vertically between the container assemblies to approximate selected medication. In some embodiments, the receptacles move vertically to approximate medication container assemblies.
According to some embodiments, the vertical arrangement of the medication container assemblies allows positioning of both the gripping assembly and the receptacles nearby a medication container assembly during the dispensing process.
According to some embodiments, reducing the distance between the gripping assembly and the receptacles affect one or more of the operational parameters. In some embodiments, the operation parameter is affected by a minimal movement of a medication dosage, between extracting from a medication container assembly and disposing the dosage into a receptacle. In some embodiments, the gripping assembly and the receptacles are both coupled to a gripping assembly and move together. In some embodiments, the dispensing rate is affected by reducing movement of the gripping model in respect to the receptacle and/or vice versa.
According to some embodiments, there is no horizontal movements between the gripping assembly and the medication receptacles after taking a medication dosage. A potential advantage of reducing the horizontal movements is reducing the medication dispensing time to increase the medication packaging rate.
A broad aspect of some embodiments of the invention relates to the arrangement of assemblies of a medication dispensing system that affect usability.
According to some embodiments, the interior arrangement improves usability parameters related to system preparations, system operations, and/or system maintenance. In some embodiments, the interior arrangement affects the size of the system, which enable positioning the dispensing system closer to operators. In some embodiments, the interior arrangement improves the convenience of accessing the medication container assemblies. In some embodiments, the interior arrangement increases the dispensing rate and reduces wait time of a user for packaged medication.
An aspect of some embodiments of the invention relates to a medication dispensing system having medication container assemblies arranged vertically.
According to some embodiments, the dispensing system comprises one or more medication panels, and the medication container assemblies are disposed vertically on the panels. A potential advantage of having a medication panel extending vertically is reducing the horizontal sized of the panel. In some embodiments, reducing the horizontal sized of the panel reduces the horizontal size of the system.
According to some embodiments, the medication dispensing system has a gripping assembly configured to move vertically to a proximate one or more of medication container assemblies arranged vertically on a panel.
According to some embodiments, optimizing the arrangement of the medication container assemblies at the panels, reduces the travel trajectory of the gripping assembly. In some embodiments, optimizing the arrangement is in accordance to historical data of the gripping assembly movements and/or medication dispensed by the system, and/or a dispensing plan. In some embodiments, the location of the medication container assemblies is determined by data about the medication usage.
According to some embodiments, the gripping assembly has a portion configured to rotate between being positioned to pick a medication out of the medication container assembly, and being positioned above a receptacle for dispensing the medication dosage into the receptacle. A potential advantage is minimizing the time the container assembly is left open between holding a medication by the gripping assembly and releasing the medication dosage. In some embodiments, the time between the grabbing a medication dosage out of the medication container assembly and the dispensing of the medication dosage in a receptacle is shorter than 10 sec. Another potential advantage is reducing accidental loosing of the medication dosage from the gripping assembly prior to the dispensing of the medication dosage in a medication receptacle.
According to some embodiments, the medication container assemblies are slanted to a vertical plane. In some embodiments, positioning the medication container assemblies in a slanted orientation, improves the accessibility of a medication opening, used to extract medication out of the medication container assemblies. In some embodiments, positioning the medication container assemblies in a slanted orientation reduces at least some of the horizontal movements of the gripping assembly.
According to some embodiments, the gripping assembly is not actuated horizontally away from the container assembly between extracting the medication dosage from the container assembly and dispensing the medication dosage within the medication receptacle. In some embodiments, the maximal horizontal distance between the gripping assembly and the container assembly remains constant between extracting the medication dosage from the container assembly and dispensing the medication dosage within the medication receptacle. A potential advantage of reducing the maximal horizontal distance is reducing the horizontal size of the system.
An aspect of some embodiments of the invention relates to a medication dispensing system having medication container assemblies arranged vertically at a medication panel, and one or more of the container assemblies are accessible by an operator, without moving other container assemblies disposed at the panel.
According to some embodiments, the vertical arrangement of the medication container assemblies enable an ad-hoc access to a medication container assembly. In some embodiments, the access is possible during a dispensing operation. A potential advantage is enabling an un-scheduled access to the medication container assembly. Another potential advantage is reducing access restrictions to the medication containers, e.g. due to a requirement to idle the dispensing system.
An aspect of some embodiments of the invention relates to a medication dispensing system having medication container assemblies having a slanted medication-guiding surface.
According to some embodiments, the guiding surface directs a medication dosage within the container assembly towards a probe used for extracting a medication dosage out of the container. According to some embodiments, the container assemblies are disposed in a slanted orientation at the panel, so that the guiding surface is not horizontal and guiding the medication dosage is by the gravity force. A potential advantage is increasing the availability of medication dosage in proximity to the probe instead of accumulating away of the probe. A potential advantage is increasing the predictability of the percentage of medication extracted of the container assemblies.
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.
