No
The summary describes a device for non-invasive pressure measurements and waveform recordings using air plethysmography. There is no mention of AI or ML in the intended use, device description, or any other section. The technology described is based on standard physiological measurement principles.
No
The device is used for non-invasive Pulse Volume waveform Recordings (PVR) and to measure and control pressure in a blood pressure cuff, which are diagnostic and monitoring functions, not therapeutic.
Yes
The device performs "Pulse Volume waveform Recordings (PVR) on extremities of patients with vascular diseases," which involves collecting physiological data to assess a patient's condition.
No
The device description clearly outlines hardware components such as a modular unit, a display, a balloon pump, a pressure transducer, and the need for a standard blood pressure cuff. It is part of a larger hardware system (PeriFlux System 5000).
Based on the provided information, the PF 5050 Pressure Unit is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- PF 5050 Function: The PF 5050 Pressure Unit performs non-invasive measurements on the extremities of patients. It uses air plethysmography via a blood pressure cuff to record Pulse Volume waveforms (PVR) and measure/control cuff pressure. These are physical measurements taken directly from the patient's body, not tests performed on samples outside the body.
The device is used for in vivo measurements, meaning measurements taken within a living organism.

Intended Use / Indications for Use
The PF 5050 Pressure Unit is intended for Pulse Volume waveform Recordings (PVR) on limbs and digits.
It is also intended to measure the mean pressure in a blood pressure cuff to simplify simultaneous measurements of perfusion and pressure when used in conjunction with a laser Doppler perfusion monitor. This simplifies some typical laser Doppler measurements that include occlusions with blood pressure cuffs. such as: digital systolic blood pressure, Post Occlusive Reactive Hyperemia (PORH) and Skin Perfusion Pressure (SPP).
When installed in the PeriFlux System 5000, the PF 5050 Pressure Unit is intended to monitor Pulse Volume waveform Recordings (PVR).
When used together with PF 5010 LDPM Unit (laser Doppler unit) it is also possible to record Skin Perfusion Pressure.
Use of the PF 5050 Pressure Unit is indicated for non-invasive Pulse Volume waveform Recordings (PVR) on extremities of patients with vascular diseases.
It is also intended to measure and control the pressure in a blood pressure cuff to simplify simultaneous measurements of perfusion and pressure when used in conjunction with a laser Doppler perfusion monitor.

Device Description
The PF 5050 Pressure Unit is a modular unit that can be installed in the PeriFlux System 5000. The device provides Pulse Volume waveform Recordings (PVR) on various limb and digit extremities made possible through air plethysmography. The PF 5050 Pressure Unit includes a small display where the mean cuff pressure is displayed.
The PVR tracing is accomplished by attaching a standard blood pressure cuff on various areas of the extremities. To provide skin contact, atmospheric air is inflated to approximately 50 - 65 mmHg using the balloon pump supplied with a standard blood pressure gauge. A pressure transducer records the pressure change in the cuff (Pulse Volume waveforms) secondary to change in v the extremity segment under the cuff during repeated cardiac cycles.
The PeriFlux System 5000 is a multi-channel, multi-functional system capable of hosting one, two, three or four function units including for example a PF 5010 LDPM Unit for blood perfusion measurements. The PeriFlux 5001 Main Unit accommodates up to four different function units of the same type or of different types enabling simultaneous measurements of several parameters. There are three different function unit types available at the moment.
PF 5010 LDPM Unit for blood perfusion measurements.
PF 5020 Temp Unit for temperature measurements.
PF 5040 tcpO2 / pCO2 for measurements of transcutaneous O2 and CO2.
The PeriFlux System 5000 with the Modular laser Doppler system for blood perfusion measurement was cleared for marketing under 510(k) application K974285 on May 28, 1998.

Technological Comparison:
The Vasamedics MODEL PV2000 VASCULAR MICROLABORATORY has the . same indications for use as the PF 5050 Pressure Unit in that they both are measuring Pulse Volume Waveform Recordings (PVR). When the PeriFlux System 5000 also includes a PF5010 laser Doppler perfusion monitor it is possible in both instruments to measure Skin Perfusion Pressure.
The instruments provide similar types of tracings and have comparable output ranges. Both instruments can be connected to external devices for data analysis
