No
The description mentions an "in house algorithm" for calculating ABI values, but there is no mention of AI, ML, or any related concepts like training sets, test sets, or specific AI/ML techniques. The process described is automated measurement and calculation based on physiological data.
No.
The device measures physiological parameters (ABPI/ABI, PVR) to assess for peripheral arterial disease (PAD) and aid in wound care assessment; it does not directly treat or provide therapy for any condition.
Yes
The device is intended for rapid measurement of ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) and pulse volume recording (PVR)/volume plethysmography to identify patients at risk of having or developing peripheral arterial disease (PAD). This falls under the definition of a diagnostic device as it measures physiological parameters to aid in the identification or diagnosis of a disease.
No
The device description clearly outlines hardware components such as cuffs, a device unit with soft touch buttons, an LCD display, and a printer, which are integral to its function of measuring and displaying ABI and PVR.
Based on the provided information, the Dopplex Ability is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Dopplex Ability Function: The Dopplex Ability directly measures physiological parameters (blood pressure and pulse volume) from the patient's limbs using cuffs and pneumo-plethysmography. It does not analyze specimens taken from the body.
Therefore, the Dopplex Ability falls under the category of a non-IVD medical device used for physiological measurement and assessment.

Intended Use / Indications for Use
Dopplex Ability is indicated for use on adult subjects at risk of having or developing peripheral arterial disease (PAD).
Dopplex Ability is intended for rapid measurement of ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) in adults and pulse volume recording (PVR) / volume plethysmography.
It is suitable for use in woundcare assessment, for assessing symptomatic PAD, and as a screening device for PAD. It may also be used on patients with venous or arterial ulcers prior to the application of compression therapy. Dopplex Ability can be used on patients with unilateral lower limb amputation.

Device Description
Dopplex Ability is intended to measure a patient's Ankle Brachial Index (ABI) and provide PVR. This is done through an automated process.
The operator places the four colour coded cuffs on each of the patient's limbs as described in the instruction for use and connect to the device.
When connected the operator pushes soft touch button to start measurement, the device then will automatically control the inflation / deflation of the cuffs on each limb and monitor minute variations in individual pressures to determine values to be used for the calculation of the ABI values for both the left and right hand of the patient.
Dopplex Ability uses pneumo-plethysmography uses obtain physiological measurements from patient's limbs. Measurements are conducted as a single occurrence on all four limbs, eliminating any requirement to rest the patient between measurements.
The test period takes approximately 3 minutes. The ABI indices are calculated using an in house algorithm.
ABI values are displayed on the LCD and can also be printed. In addition, records are generated of the Pulse Volume Waveforms (PVR), which may also be displayed on the LCD and can be printed.
