Indications for Use
The SonoTT FlowLab® with the accessories is a system to measure the flow rate of liquids (e.g. blood) with the ultrasonic transit-time and velocity patterns of blood with Doppler method. It supports the planning, implementation, efficiency control and documentation of interventions carried out in the area of cardiovascular, vascular and, transplantation, or the monitoring of extracorporeal circulatory systems. The following medical applications are supported: Intraoperative blood flow measurement with the SonoTT Vascular Probe to assist e surgeons at surgical interventions Measurement of flow direction and velocities of blood in vessels using the SonoTT Pulse Wave Doppler Probe to assist the surgeon in the non-invasive assessment of vascular changes. Extracorporeal flow measurement in continuous operation on tube systems in combination with the SonoTT Clamp-On Transducer in intensive care units and operating theatres The following actions can be performed simultaneously when these measurements are in progress: Pressure measurement in combination with a standard blood pressure transducer Secondary displays of additional physiological analogue signals and corresponding derived parameters The SonoTT Vascular Probe is intended for transient use only with continuous contact with patient of less than 60 minutes. For the patient's safety they must be operated by qualified medical personnel.
Device Story
SonoTT FlowLab measures liquid/blood flow and velocity using ultrasonic transit-time and Doppler methods. Inputs include ultrasonic signals from Vascular Probes, Pulse Wave Doppler Probes, or Clamp-On Transducers, plus auxiliary inputs like blood pressure and ECG. Device processes signals to calculate flow rates, velocities, and derived physiological parameters. Used in ORs and ICUs by qualified medical personnel to assist surgeons during cardiovascular, vascular, and transplant procedures, or to monitor extracorporeal circuits. Output displayed to clinicians for real-time intraoperative guidance, efficiency control, and documentation. Benefits include non-invasive assessment of vascular changes and monitoring of extracorporeal flow, aiding surgical decision-making.
Clinical Evidence
Bench testing only. Testing included electrical safety, EMC, ultrasonic acoustic output, alarm functionality, software validation, mechanical stability, packaging, biocompatibility of probes, sterility of vascular probe, and usability validation.
Technological Characteristics
Ultrasonic transit-time and Doppler measurement principle. Components include Vascular Probe, Pulse Wave Doppler Probe, and Clamp-On Transducer. Supports auxiliary inputs (ECG, blood pressure). Connectivity includes secondary displays for analog signals. Biocompatible materials used for patient-contacting probes. Transient use (<60 min) for vascular probes.
Indications for Use
Indicated for adult and pediatric patients requiring intraoperative blood flow measurement, assessment of vascular changes via Doppler velocity, or extracorporeal flow monitoring in ICU/OR settings. Contraindicated for: measurements on stented vessels; fetal (prenatal/neonatal) examinations; ophthalmology, gynecology, or obstetrics; monitoring vital physiological parameters; or using the Clamp-On Transducer on human arteries/veins.
Regulatory Classification
Identification
A cardiovascular blood flowmeter is a device that is connected to a flow transducer that energizes the transducer and processes and displays the blood flow signal.
