Elderly and chronically ill patients are dependent on the support of relatives or nursing services. However, that reliable support was more difficult to maintain during the COVID-19 crisis as disease-related absences of relatives and overworked nursing staff put significant strain on resources. If invention is the mother of necessity than the newly developed digital medication management system TAB in TIME is proof of that, as it offers a solution for chronically ill patients to be supplied with vital medication with minimal involvement of support personnel.
The beauty of TAB In TIME is in its details. After filling the device in the morning, the unit provides up to five individual time settings in which to dispense medication as well as the appropriate amount of water. TAB in TIME also has visual and acoustic reminders for the proper release of medication and more importantly, automatically notifies the registered contact person via text message in the case of incorrect or omitted doses. This can be the nursing staff or a relative. Because of these advanced features, TAB in TIME guarantees the optimal delivery of critical medication in homes, as well as healthcare facilities such as nursing homes or hospitals.
For TAB in TIME, AKVIGO selected Garz & Fricke to develop the device’s entire control unit. The implemented HMI (Human Machine Interface) consists of a display, touch, computing unit, and the corresponding mechanics, all integrated and designed as a panel mount version. For this interface, Garz & Fricke developed a ready-to-use mechanical installation concept for easy integration, as well as reliable sealing on the front according to enclosure protection class IP66. The heart of the system is the Garz & Fricke single board computer: SANTINO LT. At AKVIGO the ready-to-install HMI module is simply inserted through the housing cut-out on the front of the device and fastened inside with several clamps.
Gabriele Bunse CEO AKVIGO GmbH states that the close collaboration between the two companies was critical in successfully developing TAB in TIME: “We knew Garz & Fricke had the requisite know-how, but what impressed us most was the personal commitment of the employees and their patience with the necessary and continuous improvement process.”
Efficient Customization of Standard Components
According to James Hoagland, Senior Solutions Engineer of Garz & Fricke Inc in the U.S., the secret sauce is the company’s ability to achieve a high level of customization using standard components, “In the case of TAB in TIME, we adapted our standard “SANTINO LT 5.0” HMI as a panel mount, upgraded the unit seals to meet the IP66 rating and streamlined mechanical installation to meet the usage requirements of the system. And all this in the shortest possible time.”
Additionally, since the automatic tablet dispenser sends a warning message to the registered contact person if the medication is not taken correctly, communication via WLAN, Bluetooth or LTE is critical and must be guaranteed. Due to the limited space available, the Garz & Fricke designers opted for a combination of a compact Wi-Fi/Bluetooth module and an external LTE modem. As a result, the software developers at Garz & Fricke made a necessary driver adjustment in the panel’s Board Support Package (BSP).
Another modification included a specialized keypad cable for connecting the customer’s own stock beacon board had to be added, which Garz & Fricke then pre-assembled to the single-board computer by adding a specially designed cable bushing.
Ultimately, AKVIGO was able to realize its specialized device thanks to its close collaboration with Garz & Fricke’s and their ability to apply an innovative and customized approach across all aspects of the device’s design and functionality.
