Abstract

Background and Aims

Peripheral Arterial Diseases (PAD) have been a recurring issue on Diabetes Treatment. The best solution, as has been reported by physicians and researchers worldwide is a timely diagnosis. Currently, the best non-invasive method for PAD diagnosis is measuring the Ankle Brachial Index, which is based on the ratio between systolic pressure on the superior and inferior limbs. It is a time-consuming method that requires, generally, a sphygmomanometer and a Vascular Doppler device. In patients with Diabetes, detection of the blood wave pulse with the Doppler device can be difficult for non-experienced physicians and the high cost of proper equipment leads many clinics to not investing in their acquisition. An alternative device is therefore needed. We present in this work a solution for this issue, by means of an automatic measuring device for diagnosing PAD in a short time period and exempting the user from the necessity of the Doppler device.

Methods

We developed a non-invasive device made of low-cost components for diagnosing PAD. It is remotely controlled by cellphone (trough Bluetooth connection) and, by using a Pulse Sensor, it records the pulse waves and performs the pressure measurement, automatically presenting on the smartphone screen the final ABI result and diagnosis.

Results

The device is currently on the validation phase and has presented accurate results. The interface is easy to use and self-explanatory, as shown in the following figures. The average measuring time is 5 minutes.

Conclusions

Our device is presenting correct measurements and practicality of use. Further clinical tests must be performed.
