The TSI mHealth app is designed to be simple enough for patient self-examination. Although, results are intended only for providers.
It is designed to run on about 7 billion phones globally without any additional hardware or gels. Mobile phones can be excellent diagnostic devices as they have strong infrasonic sensitivity and can support recording speeds that are 50 times faster than the leading digital stethoscope. However, mobile phones are not designed to be diagnostic devices and the TSI app contains many proprietary aspects that ensure that consistent observations are made regardless of phone brand, phone position, patient demographics, or patient body-type.
In its current form, the TSI mHealth app is designed to support clinical study and not for commercial commercial use. However, it contains much of the same essential functionality of a minimum viable product. Multiple examination sites are supported and the application also has the ability to store key patient data such as response to standard screening questions, information about medications and co-morbidities, demographics and body measurements.
The TSI device will make new information available to providers that helps them optimize treatment plan and, thus, improves outcomes. The device is not intended to replace gold standards or physical examination; but to provide a robust option in situations where gold standards do not exist. Examples of potential applications include:
- Remote patient examination as part of regular checkup or in response to acute symptoms.
- Remote patient monitoring of significant changes to baseline of previously diagnosed conditions.
- Prescreening before in-office provider examination. This could be conducted at home or in-office by PA.
- Uniformed first response which includes but is not limited to EMS.
- Medical counter measure which includes both population health surveillance and rapid response diagnostic trained for specific infectious or chemical conditions.
In addition, the TSI device can also be used in clinical trials to monitor patient safety and provide new insights into both phenotypic Ing and pharmacological dynamics/kinetics.
The methodologies employed by the TSI using the mobile phone can be applicable to other devices as well. Some examples are on our Other Devices page.
