In the previous part of this blog, we began looking at the various sensing methods that would be used to monitor some patient parameters. The intent was to see if we could move much of the sensing and processing onto a single piece of silicon. We'll continue looking at this lab- or doc-on-a-chip.
We can monitor blood pressure, heart rate, and temperature. Then we add to that gas and pressure sensors for monitoring respiration and detecting abnormalities in body chemistry. We add a communications section to pass the data to a monitoring station. But there's more we should be able to do.
An integrated lab-on-chip system should check for the presence of bacteria and viruses on the biological samples of a patient. See Figure 1.
To secure the privacy of the data coming from the portable SoC station (containing the silicon-based integrated medical sensors) a very interesting solution has been developed. This new portable device will record the personal data of the patient and store it. Then a fingerprint is required to access the data. The device, known as I-Memo, is based on biometric fingerprint recognition of the user/owner. This fingerprint recognition will enable:
- Recording of sensitive data and third-party info, as well as codes, in the form of protected, encrypted, and controlled access info, according to the latest standards and regulations in force
- Managing mobile data such as PIN codes and credit card numbers, or access codes and digital signatures strings, and keeping all absolutely unassailable; both hardware and software have been developed to rule out any attempt to attack
- The ability to work and access the same database of codes, passwords, and data from both the computer and mobile office
This type of application can, for example, allow an immediate action by the emergency medical personal. This can enhance the probability of surviving serious medical events like a heart attack or a stroke. These are the situations where fast action makes the difference in survival probability of a patient. An Internet-of-Things object, when used to monitor the medical parameters of a patient, can effectively send an alarm message. Data would be monitored and saved (in a safe, personal storage IC, like the I-Memo). These statistics for the patient's physical condition can really help with treatment.
Do you think this system will be useful to develop a portable medical center based on silicon sensors and on integrated lab-on-chip technology? What do you think about the privacy of the medical data of a patient guaranteed by this kind of solution? Have you had experience with portable checkup systems like this one? Do you think that the overall system will be compliant with safety rules and regulations of the market in which the system will be present? Do you think that the lack of harmonization of medical regulation rules in different countries may be an issue?
