The present disclosure relates to systems and methods for increasing patient adherence to medication and nutrition regimens and, more particularly, to a smart pill cap for use with standard prescription medicine containers.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Many people take medications, vitamins, and nutritional supplements on a regular basis as a way of life. However, a common problem is that people forget to take their medications or other pills on a regular basis, or as they are prescribed. Experts have estimated average medication adherence rates of 50% to 60%. According to the National Community Pharmacists Association, this costs about 125,000 lives and $290 billion in the United States alone. While there are several factors behind non-adherence, several studies have indicated that forgetfulness is a driving factor.
In light of these facts, there is a continuing need for a cost effective system and method of promoting patient adherence to medication and nutrition regimens. Desirably, increasing rates of patient adherence will improve patient outcomes, saving patient lives and reducing preventative costs borne by the healthcare system and society.
In concordance with the instant disclosure, a cost effective system and method of promoting patient adherence to medication and nutrition regimens, which improves patient outcomes, saves patient lives, and reduces preventative costs borne by the healthcare system and society, is surprisingly discovered.
The present disclosure provides a device and method to assist people with managing either a) their medications or b) the medications of somebody whom they are caring for. In one embodiment of the disclosure, these medications are placed into a standard prescription pill container that is labeled and filled by a pharmacist. The standard prescription pill vial has a smart pill cap. Information about the medication, including the medication schedule, are programmed into a software application that connects to the smart pill cap attached to the pill container. The smart pill cap detects interactions with the pill container, including when it is opened and closed, and sends this information wirelessly to a remote computer. The remote computer can remind the user to take their medications when they forget. The remote computer can also send the user's medication adherence data to a remote server, where it may be shared with family members or their healthcare providers. The system can remind patients when to take their medications, provide information about the medications, monitor adherence to the prescribed medications, and can transmit this information to authorized individuals who can further assist patients in managing their conditions.
In one embodiment, a cap for a medication container includes a housing with a top portion and a bottom portion. The top portion and the bottom portion together define a cavity therebetween. A sliding plate is disposed in the cavity adjacent the bottom portion. A microcontroller with a switch type contact sensor is disposed in the cavity between the top portion and the sliding plate. The sliding plate is configured to slide toward and activate the contact sensor where the cap is secured to the medication container in a closed state. The sliding plate is configured to slide away from and not activate the contact sensor where the cap is removed from the medication container in an open state.
In another embodiment, a system for promoting adherence to a regimen by a patient includes the cap, and a first remote computer having a memory and a display. The first remote computer is in electronic communication with the cap. The first remote computer is configured to show on the display information corresponding with the sliding plate pressing against and activating the contact sensor. The information is indicative of an opening and a closing of the medication container over time.
In a further embodiment, a method for promoting adherence to a regimen by a patient, includes the steps of providing the system with the cap and the first remote computer, and maintaining the cap in a standby mode until the cap senses a change in state from one of the open state and the closed state. The cap is then caused to enter an active mode for a predefined period of time. The cap is configured to record the information from the contact sensor while in the active mode. The microcontroller of the cap then creates a sensor data log of the information, and communicates the sensor data log to the first remote computer.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The above, as well as other advantages of the present disclosure will become readily apparent to those skilled in the art from the following detailed description when considered in light of the accompanying drawings, in which:
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
In a particular embodiment, a top plate 103 is incorporated into the smart pill cap 101 that can be removed in order to expose a coin cell style battery. A gap 104 between the top plate 103 and the primary container body 105 permits the top plate 103 to be removed via a prying action, as well as permits sound emitted by the internal speaker to be heard by the user.
A silicone band 106 provides an improved grip on the smart pill cap while concealing a seam between the top and bottom portions of the smart pill cap assembly. The silicone band 106 may also be colored in a way that the user associates it with the display of one of their medications in the accompanying software of the smart pill cap 101.
The smart pill cap 101 can be placed on a prescription or over-the-counter pill container in order to track medication usage and adherence. The container 102 may be filled by a pharmacist, drug manufacturer, drug distributor, or wholesale provider.
The printed circuit board contains a switch type sensor 204, a wireless radio, memory, a speaker, and other electronic components. A sliding plate 204 is also encased by the top piece 201 of the housing and the bottom piece 202 of the housing. The sliding plate 204 presses down the switch type sensor 205 when the pill container 211 is attached to the smart pill cap 101 by tightening the threads 206 on the container with the threads 207 internal to the smart pill cap.
A silicone band 208 may be placed on the outside of the assembled smart pill cap 101. The silicone band 208 may fit into a groove 209 that permits a flush fitting within the side of the smart pill cap 101. The silicone band 208 may cover up screw holes 210 that are used to attach the top piece 201 and the bottom piece 202 of the smart pill cap 101.
The remote computer receives has the capability to store data from the smart pill cap in local memory 511. The remote computer also contains an onboard power 510 source, such as a lithium ion battery. Most importantly the remote computer serves as the user's primary means of viewing data that is collected by the smart pill cap, with the user of the smart pill cap having the ability to view said data on the display screen 512 of the remote computer 512 as well as to input data that can be sent from the remote computer 508 to the smart pill cap 501, such as a schedule of times when the user is supposed to take the medications contained by the smart pill cap 501 and the pill container that it is mated to.
Data related to the user's medication adherence may be stored in the smart pill cap, the remote computer, and on the remote server, with data periodically synced across all three locations. Medication adherence data stored on the smart pill cap may be deleted after a specified number of events in order to free up additional memory, preferably after data is pushed to the remote computer or remote servers. Information may also be sent from the remote servers to the user's remote computer. For example, information may be sent to the user's smartphone related to pricing at various pharmacies where they can refill their medications.
Optionally, a portion of the data captured by the smart pill cap may be shared from the remote servers to additional remote computers 607 that are managed by remote caregivers, care managers, family members, or healthcare professionals (doctors, nurses, physician's assistants, etc.). This sharing is likely to be executed via an application programming interface (API) that is made available to users that have 1) received permission from the owner of the smart pill cap and first remote computer 2) have proven their credentials to the API through an authentication method, such as OAuth, a known open standard for authorization, or a token-based authentication method. This capability provides additional users to see information that can help them to care for the user, such as to intervene when the user has deviated from their medication schedule. Moreover, the API enables 3rd party solution providers to write custom software applications that combine data from the smart pill cap with data from other sources. For example, the additional remote computers may combine data from the smart pill cap with data from a wireless scale or a wireless blood pressure monitor to determine if the user has a high degree of risk of heart attack due to the user's deviation from their prescribed medication regimen.
As shown in
In another embodiment, the pushbutton itself is used as a capacitive weight sensor.
In yet another embodiment, a load sensor is used that is attached to the printed circuit board.
In a further embodiment, scattered light is used to measure the distance between the PCB and the sliding plate. An infrared LED and complementary photoreceiver are placed in proximity on the side of the printed circuit board that is facing the sliding plate. Scattering from the sliding plate results in reflections of a portion of the illuminated light onto the photoreceiver, with the intensity of the light being proportional to the distance between the two plates. This illumination is best enabled in short bursts or on command in order to conserve energy.
From the foregoing description, one ordinarily skilled in the art can easily ascertain the essential characteristics of this disclosure and, without departing from the spirit and scope thereof, make various changes and modifications to the disclosure to adapt it to various usages and conditions.
This application claims the benefit of U.S. Provisional Application No. 62/036,272, filed on Aug. 12, 2014. The entire disclosure of the above application is hereby incorporated herein by reference.
