The invention is herein described, by way of example only, with reference to the accompanying drawings, wherein:
The present invention is a pill dispenser for dispensing medications, vitamins and/or dietary supplements.
The principles and operation of the dispenser according to the present invention may be better understood with reference to the drawings and the accompanying description. The dispenser is applicable to a wide range of applications including prescription and non-prescription medications, vitamins and dietary supplements, in forms ranging from hard tablets through various types of capsules, which may be filled with liquid or solid materials, referred to collectively as “pills”. For brevity of description, reference is made below simply to “medications” or “pills”, but it should be understood throughout that these terms are used interchangeably with vitamins, dietary supplements, tablets, capsules, and any other products that are suitable for dispensing with the device described herein.
Referring now to the drawings,
A first sleeve 22 (shown separately in
Second sleeve 26 is rotatable relative to first sleeve 22 about central axis 16 to bring each of the staggered openings 28 selectively into alignment with elongated slot 24, thereby providing access to a single one of the compartments 14 of core 12.
According to one aspect of certain particularly preferred but non-limiting embodiments of the present invention, core 12 is implemented with a plurality of axially removable cartridges 30, each including at least one row of compartments 14.
It is particularly preferred that removable cartridges 30 can be inserted while compartments 14 contain pills, so that the cartridges can be filled with the appropriate dosing regimen of medications, vitamins and/or dietary supplements outside the device and then inserted into the device, rendering the device immediately ready for use. For this purpose, removal and insertion of the cartridges may advantageously be performed while the cartridge is held with the compartments 14 opening upwards, as is illustrated in the sequence of
In the particularly preferred example illustrated here, each cartridge 30 provides exactly one of the rows 18 of compartments 14, and each row of the compartments includes at least 7 compartments. Typically, the number of compartments per cartridge is in the range of 7-10, depending on the intended application as discussed further below, although other numbers of compartments may be suited to alternative applications. Each of the cartridges 30 preferably spans a sector of core 12 corresponding to between about 80 degrees and about 120 degrees about the central axis. This corresponds to either 3 or 4 cartridges which together encompass most of the periphery of the core.
Thus, the particularly preferred implementation as illustrated here provides 7 layers, each subdivided into 4 compartments, where each cartridge 30 is a segment, in this case a quadrant, of core 30, carrying one row of 7 compartments 14, providing one compartment of each layer. The cartridges preferably slide in and out independently from a support structure, which may be a central spindle or holder with one or more feature for receiving each cartridge. Alternatively, in some cases, the cartridges may be implemented so as to interlock directly with each other without a separate support structure (not shown).
In the example illustrated here, as best seen in
Preferably, each cartridge 30 and support structure 32 have complementary engagement features for retaining the cartridge in its fully inserted position during use. In the non-limiting example illustrated here, each cartridge is provided with a resilient slotted pin 36 which has a head sized to engage a corresponding aperture 38 in flange 34.
Each cartridge thus has a row of compartments for receiving a sequence of medications, which may correspond, for example, to a daily dosage of medications to be taken once a day or a dosage of medications to be taken at a certain time of the day. The ability to load these cartridges outside the device opens up possibilities of having a “refill kit” prepared, separate from the dispenser that is in use, ready for quickly and easily replenishing the contents of the dispenser. Specifically, a refill kit preferably includes a number of cartridges 30 corresponding to the capacity of the dispenser, where each of the cartridges containing medications, vitamins and/or dietary supplements, typically according to a personalized dosage regimen. A closure arrangement is provided for retaining the medications, vitamins and/or dietary supplements within compartments 14 prior to insertion of the cartridges into the pill dispenser.
One such example of a refill kit is illustrated in
Additionally, or alternatively, a refill kit may be provided pre-filled by a medication supplier (pharmacist or other) with specific medications and dosages required for a certain patient preloaded in the correct sequence and quantities. The preloaded cartridges are preferably sealed, such as with a sealing layer of polymer film applied to seal the compartments. The preloaded cartridges may be supplied individually or in a common tray (as shown), to be provided to the user for self-loading of the dispenser. In some cases, prefilling and sealing of the cartridges may be performed automatically by an automated medication dispensing system. The sealing layer may be removed manually by the user (or caregiver) prior to insertion of the cartridge into the dispenser. In certain cases, the cartridge may be inserted without prior removal of a sealing layer. In this case, a cutter (not shown) may optionally be incorporated into the dispenser for removing the sealing layer during insertion, or for rupturing it for each compartment as part of the relative movement of the device components during dispensing.
Thus, a further aspect of an embodiment of the present invention is a method which provides medications according to a personalized dosage regimen preloaded and sealed in cartridges, with multiple compartments per cartridge, where the cartridge is directly loaded into a mechanical dispenser configured to sequentially make available the contents of one compartment at a time. Most preferably, the dispenser accommodates a plurality of the cartridges simultaneously, such as is exemplified by the dispenser described herein.
In order to facilitate correct insertion of the cartridges in corresponding positions within the dispenser, the cartridges are preferably color coded, for example, being formed in their entirety from plastic of colors corresponding to colors indicated on the indicator ring of the device core (as discussed further below), thereby indicating a corresponding required position of insertion relative to the support structure. Additionally, or alternatively, the corresponding positions of the cartridges relative to the core may be indicated by various indicia and/or graphic elements. Additionally, or alternatively, insertion of a cartridge 30 in an incorrect position relative to the support structure of core 12 may be mechanically obstructed, for example by varying the positions of the aforementioned pin-and-aperture engagements between the support structure and the cartridges for each cartridge and its corresponding insertion position, or by providing additional distinct engagement configurations (not shown) for each cartridge and its corresponding position.
Turning now to additional structural features relating to the removal and insertion of cartridges 30, in order to provide additional retention of the cartridges within the device during use, one or both of first sleeve 22 and second sleeve 26 is preferably formed with an end wall 46 having a cartridge-insertion opening 48 shaped to selectively allow removal and insertion of one of the cartridges only when the opening is properly aligned with the cartridge (
Pill dispenser 10 is preferably provided with a spring-loaded mechanism which defines a number of discrete stopping positions for the relative motion of second sleeve 26 relative to first sleeve 22, and similarly of core 12 relative to first sleeve 22, such that each element is felt to “click into place” relative to each other. Such an effect can be achieved using a wide range of simple mechanical solutions including, but not limited to, spring-loaded bearings, leaf spring elements, and other forms of mechanical engagement. Most preferably, the spring-loaded mechanism also limits the direction of relative rotation to a single direction, acting as a ratchet. One particularly simple implementation to achieve these functions is the use of resilient spring-inserts 50 with a directional ratchet tooth, as seen in
In the particularly preferred implementation illustrated here, end wall 46 and cartridge-insertion opening 48 are integrated with second sleeve 26. Most preferably, one of the discrete stopping positions of second sleeve 26 relative to first sleeve 22 is a designated “filling position”, distinct from the various dispensing positions in which staggered openings 28 are aligned with elongated slot 24. Where filling is to be performed exclusively by insertion of cartridges which are filled outside the device, the filling position may correspond to alignment with elongated slot 24 of an axial strip 54 of second sleeve 26 without openings (see
In order to provide an option for manual filling of the device when the cartridges are inserted (and also for embodiments of the invention which use a fixed core without removable cartridges), second sleeve 26 preferably also includes an axially-extended opening 56 such that, when axially-extended opening 56 is aligned with elongated slot 24 of first sleeve 22, all compartments of one row of the core are accessible, as illustrated in
In order to facilitate removal of the cartridges, each cartridge is preferably provided with a resilient pull-tab 58 which is manually accessible via cartridge-insertion opening 48 when the cartridge is aligned with the opening.
In the particularly preferred implementation illustrated herein, core 12 has 4 compartments per layer, and therefore 4 indexing positions relative to first sleeve 22. Second sleeve 26 has 7 staggered openings 28 corresponding to the 7 layers of the core, plus closed strip 54 and axially-extended opening 56, making a total of 9 indexed positions relative to first sleeve 22. Since 4 and 9 are coprime, none of the positions of second sleeve 26 other than the designated filling position will have the cartridge-insertion opening correctly aligned with any of the cartridges, thereby ensuring that a cartridge cannot be removed except when the device is in the filling position.
In certain particularly preferred implementations, for example as illustrated herein, the status of the device defined by relative positions of the core, the first sleeve and the second sleeve, are readily visible from the radially-outward surface of the dispenser. In this case, first sleeve 22 has a radially-visible indicator marking 60, which is here incorporated into a ring 62 which mounts on an outwardly projecting flange 64 associated with first sleeve 22 (
Pill dispenser 10 is preferably provided with a cover 76, selectively deployable to cover all openings of the first and second sleeves. Outer cover 76 is preferably provided in the form of a cylindrical sleeve, typically closed at one end, which serves to provide physical protection for the dispenser when not in use, as well as protection of the medications from UV radiation, and serves to prevent inadvertent release of medications and/or ingress of dirt or foreign bodies into the device when not in use. When used in combination with the “closed” state of the inner-outer casings, the device provides a double closure arrangement to protect the contents of the dispenser, even under challenging conditions of motion and vibration. The outer cover also provides surfaces for images and/or writing, which may be advertising material, patient details and/or decorative content.
According to certain particularly preferred implementations, pill dispenser 10 further comprises a detachable pill box 78, releasably interlocking with the pill dispenser 10. In the preferred example illustrated in
Notwithstanding the above, it is noted that the form factor of pill dispenser 10 is significantly more compact than most devices with similar capacity. Specifically, as per the examples given above, the number of compartments 14 in each row (typically 7 or 10) is greater than a number of compartments in each of layer (typically 3 or 4). As a result of this differential, and additional aspects of the preferred configuration, an axial dimension of pill dispenser 10 is typically larger than an outer diameter of the pill dispenser. The small diameter renders the device convenient for handling, typically easily gripped by fingers of the user reaching opposite sides of the device, and fitting conveniently into a briefcase or backpack occupying a space similar to a small vacuum flask.
In use, where the open axial row of the outer casing is brought into alignment with the open axial row of the inner casing, an entire row of the central core is exposed. This is useful for manual loading of pills into the compartments of the central core, or emptying therefrom. However, if the intended mode of use of the device is exclusively through insertion of pre-loaded cartridges, an implementation of the invention without the open row in the outer casing may be preferred.
Where the closed row of the outer casing is brought into overlapping relation to the open row of the inner casing, all apertures of each casing are closed, and all of the medicament compartments remain closed.
When one of the staggered openings of the outer casing is brought into alignment with the open row of the inner casing, this results in selective opening of exactly one compartment of the central core, thereby allowing dispensing of the contents of that compartment into the hand of the user. By rotating the central core in this state, each successive compartment of the selected layer is brought into alignment with the aligned openings of the inner and outer casings, thereby allowing dispensing of the contents of that compartment.
The device may be used in a number of different modes. In the typical case of 7 layers of 4 compartments, the outer casing may be rotated by one column/step per day to select a layer (from 1-7) corresponding to a day of the week, and the core may be turned to select a corresponding period of the day, such as morning, midday, evening and night, thereby dispensing medications four times a day for a week. Alternatively, the core may be left in place relative to the inner casing for a week at a time, become a week selector. In this case, the dispenser becomes a 1×28 dispenser, suitable for dispensing medication once a day for 4 consecutive weeks, or 28 days. Most preferably, the aforementioned index surfaces 66 and 68 are labeled with appropriate labels for the intended application, for example, day names, e.g., Sunday, Monday, Tuesday etc. through Saturday on index surface 68, while index surface 66 is marked (Morning, Lunchtime, Evening, Night) or (Week 1, Week 2, Week 3, Week 4), according to the intended usage. The labels aligned with indicator 60 also serve as a visual reminder to the user as to when the last dosage was taken. Thus, if the user doesn't remember whether she took her midday dose, she can look at the dispenser to check whether the opening (last dose taken) is still set to the morning, or whether the midday dose was already dispensed.
Clearly other modes of use are also possible, such as twice-a-day for two weeks. According to one preferred implementation, the marking locations are implemented as sockets for receiving pre-labeled inserts, or as recessed panels for receiving pre-labeled stickers, to identify the corresponding time periods according to various options for use.
As mentioned above, the device is not limited to implementations with specifically 7 layers and 4 compartments per layer. For example, in an alternative implementation, the device is implemented with three compartments per layer, and/or ten layers, allowing administration of medicaments 3×7 or 3×10 (as is typical for some courses of antibiotics, or 1×30 for a 30-day month.
Most preferably, both the first sleeve 22 (“inner casing”) and the second sleeve 26 (“outer casing”) are made from material which is at least partially transparent, allowing the user to verify visually whether there are medicaments in a given (currently closed) compartment, and/or to visually verify correct alignment of the central core or to see color coding of the core segments/cartridges. Particularly for use in multiple daily doses, intuitive color coding of the cartridges making up the central core (or segments of the core in a case of a fixed core structure) is preferably used. By way of one non-limiting example, coding may include:
Optionally, hollow housing 66 may include an internal volume which houses one or more battery, preferably rechargeable, powering various electronic components, to provide additional functionality to the medication dispenser. The electronic components may include various sensors 67a for sensing the mechanical state of the device, and Bluetooth (communication) components 67b for communicating with a mobile phone or the like and/or GPS components, preferably operating a dedicated mobile APP which provides additional functionality, such as monitoring whether the device has been opened for taking the required dose at the required time, to facilitate locating of the device if misplaced and/or notifications to the mobile phone from the device according to a preprogrammed schedule. Additionally, or alternatively, a built-in clock with audio and/or indicator light timer reminders may be provided to prompt taking of medications. A removable cover 74 may be provided for concealing components that are not intended to be visible during use.
Optionally, the electronic components may also include a small motorized drive for advancing the components to the correct positions for the next medication dosage to be released. Such motorized operation may be triggered by a manual input, or may occur automatically at the programmed time.
To the extent that the appended claims have been drafted without multiple dependencies, this has been done only to accommodate formal requirements in jurisdictions which do not allow such multiple dependencies. It should be noted that all possible combinations of features which would be implied by rendering the claims multiply dependent are explicitly envisaged and should be considered part of the invention.
It will be appreciated that the above descriptions are intended only to serve as examples, and that many other embodiments are possible within the scope of the present invention as defined in the appended claims.
