DETAILED DESCRIPTION

[0031] In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. However, it will be understood by those skilled in the relevant arts that the present invention may be practiced without these specific details. In other instances, known structures and devices are discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention. It should be noted that there are many different and alternative configurations, devices, and technologies to which the disclosed inventions may be applied. The full scope of the inventions is not limited to the examples that are described below.

[0032] FIGS. 1 through 5 show a device in the form of a capsule designed for the controlled dispensing of medication.

[0033] This device may comprise a cap 101 removably and rotatably coupled to a base 102. The cap 101 may comprises a channel 106 at about a center-most point 106b of the cap 101 and a notch 107 in an outer edge 107b of the cap 101. The base 102 may comprise a rotation stem 105 protruding from about a center-most point 105B of the base 102. In the depicted embodiment, to assemble the device, the rotation stem 105 passes through the channel 106 within the cap, locking the two cap 101 and the base 102 together. To open the device for loading of medication, the cap 101 and the base 102 may be separated by detaching the rotation stem 105 from the channel 106 in the cap 101.

[0034] The device may further comprise a plurality of compartments 104 proximal to an outer edge of the base 1048 configured to house medication. As shown in FIGS. 2 and 5, the base 102 may contain thirty (30) compartments 104. The base 102, however, may contain any number of compartments 104 greater than one (1). These compartments 104 are to be loaded with a dose of medication by a medical provider. These compartments 104 are most easily accessible when the cap 101 and the base 102 are uncoupled, leaving all compartments 104 accessible at one time, as depicted in FIGS. 2 and 5. Once the medication is properly loaded within the compartments 104, the cap 101 and base 102 may be recoupled. The notch 107 within the cap 101 may be configured to facilitate ease of access to medication within the particular compartment 104 from which the patient has access at a particular time.

[0035] The device may further comprise a first lock 103 that prevents rotation of the cap 101 and the base 102 when locked. When unlocked, this lock 103 is designed to limit directionally opposite rotation of the cap 101 and the base 102 to prescribed ranges of degrees that correspond with the size of one or more compartments 104. For example, if a medical provider prescribes for a patient to have access to only one dose of medication at time, the lock 103, when unlocked, will limit rotation of the cap 101 and the base 102 so that only a single compartment 104, and the medication within that compartment 104, are visible within and accessible via the notch 107 within the cap 101.

[0036] As shown in FIGS. 1 through 5, this capsule may be substantially cylindrical. The capsule, however, may be configured in any way that allows for the cap 101 and the base 102 to be removably and rotatably coupled in a manner that allows a patient to access medication through the alignment of the compartments 104 and the notch 107 in the cap.

[0037] The device may comprise a first timing system, wherein the first timing system unlocks the first lock 103 only after a prescribed time interval since a previous rotation of the cap 101 and the base 102. Once the patient rotates that the cap 101 and the base 102 to access a dose of medication, the lock 103 will relock. The first timing system will then begin counting down until the prescribed time interval has again elapsed, signaling the lock 103 to unlock.

[0038] The prescribed minimum time interval between doses regulated by the first timing system may be uniform or varied. One non-limiting embodiment of uniform minimum times between doses is as follows: Dose 2 may be available 6 hours after Dose 1 is taken; Dose 3 may be available 6 hours after Dose 2 is taken; and Dose 4 may be available 6 hours after Dose 3 is taken; et cetera. One non-limiting implementation of varied minimum time intervals between doses is as follows: Dose 2 may be available 6 hours after Dose 1 is taken; Dose 3 may be available 10 hours after Dose 2 is taken; and Dose 4 may be available 16 hours after Dose 3 is taken; et cetera.

[0039] The device may further comprise a second timing system, wherein the second timing system prevents the first timing system from unlocking the lock 103 after a prescribed time interval. A medical provider can prescribe for the second timing system to begin counting down at a specific time or to begin when the patient first rotates the cap 101 and the base 102 to access a dose of medication. Once initiated, the second timing system counts down independent of the first timing system. Once the prescribed time interval within the second timing system has elapsed, the second timing system overrides the first timing system's ability to unlock the lock 103.

[0040] The device may further comprise, as depicted in FIG. 3, a compartment 108 and a removably coupled lid 108B. This compartment 108 may be configured to house one or more doses of medication. The lid 108B of this compartment 108 is to remain unlocked at all times. The purpose of this compartment 108 is to provide access to doses of medication outside of the medication scheduled articulated by the first timing system and the second timing system.

[0041] The device may further comprise, as depicted in FIG. 4, a second lock 109 that prevents rotation of the cap 101 and the base 102 when locked. This second lock 109 may be used to increase the likelihood that only the patient for whom the medication within the device is prescribed has access to the medication.

[0042] The device may further comprise, as depicted in FIG. 5, an insert 102B configured to removably couple to the plurality of compartments 104 proximal to the outer edge 104B of the base 102. This insert 102B may be used to prevent cross contamination of different medications housed within the compartments 104 of the device on subsequent uses of the device. This insert 102B may also be preloaded with medication in a bubble pack or other similar structure.

[0043] FIGS. 1 through 5 depict the device comprising a data port 201 to receive data into the device. The data port 201 may be used to receive information including, but not limited to, mediation type, patient information, medical provider information, prescribed minimum time between doses, prescribed maximum time during which any doses are accessible by the patient, and/or other data. The data port 201 may not be necessary in all embodiments of the device, as the previously described information may also be transmitted to the device via wireless communication.

[0044] FIGS. 1 through 5 depict the device with a battery compartment 202. The battery compartment 202 is used to house the power source for the device. The batteries housed within the battery compartment 202 may be disposable and/or rechargeable batteries. In embodiments that use rechargeable batteries, these batteries may be recharged externally from the device or while the batteries remain within the device.

[0045] FIGS. 1 through 5 depict the device with a display screen 203. This display screen 203 may include information, including, but not limited to mediation type, patient information, medical provider information, prescribed minimum time between doses, prescribed maximum time in which doses are accessible by the patient, battery life remaining, and/or other information.

[0046] The device may comprise any combination of the above described elements. For example, one embodiment of the device may include the compartment 108 and removably coupled lid 108B depicted in FIG. 3, the second lock 109 depicted in FIG. 4, and/or the insert 102B depicted in FIG. 5.

[0047] Many of the components of the embodiments described above may be commercially available. Those components that are not commercially available may be manufactured using a variety of materials suitable for their intended purposes, including but not limited to various metals, plastics, and fabrics. The cap 101, base 102, insert 102B, first lock 103, compartments 104, outer edge of the base 1048, rotation stem 105, outer edge of the cap 107B, compartment within the cap 108, lid to the compartment within the cap 108B, second lock 109, data port 201, battery compartment 202, and display screen 203 may be made of metal, plastic, glass, plexiglass, or other rigid materials.
