A device designed to graphically record the instantaneous flow (velocity) of air at the mouth or, using an integrated signal, the volume of air per breath during inspiration or expiration. This recorder consists of a resistance attachment (e.g., wire screen...

Blood flowmeter catheter, Doppler

10 GUDID devices

A device that is a flexible tube designed for insertion within the blood vessels for the purpose of determining blood-flow velocity by measuring the ultrasonic frequency shift between the transmitted and reflected signals (Doppler principle). It typically h...

Laser Doppler blood flowmeter

101 GUDID devices

A mobile, mains electricity (AC-powered) device designed to use laser Doppler techniques to measure the velocity of micro- and macrovascular blood circulation to assess of the extent of vascular flow restrictions [e.g., clots, stenosis, mechanical damage, a...

Laminar airflow hood

73 GUDID devices

A ventilated laboratory enclosure designed to prevent airborne biological contamination of laboratory specimens contained within, and personnel handling the specimen, by creating a barrier with a forced flow of uniform-velocity and parallel-direction air. I...

Intravascular haemodynamic monitoring system

9 GUDID devices

An assembly of devices used for the continuous in vivo measurement and display of blood pressure and blood flow velocity in all blood vessels, including the coronary and peripheral arteries, during diagnostic and/or interventional procedures. It typically i...

Anemometer

7 GUDID devices

A hand-held, battery-powered, digital device intended to measure airflow (velocity and volume flow rate) typically for indoor use (e.g., laboratory fume hood testing). It typically consists of a rotating vane attached, via a cable, to a digital display.

Electromagnetic blood flowmeter

5 GUDID devices

A device using electromagnetic (EM) technology to provide a method of confirming and measuring the velocity of blood flow in vessels after coronary artery bypass, organ transplant, and other vascular reconstructive surgery. It uses an invasive technique tha...

Intravascular haemodynamic monitoring system guidewire

4 GUDID devices

A sterile, steerable, component of a haemodynamics monitoring system for the in vivo measurement of blood pressure and/or blood flow velocity in all blood vessels, including the coronary and peripheral arteries, during diagnostic and/or interventional proce...

Mobile laminar airflow unit

2 GUDID devices

A device designed to displace the entire air mass within an enclosure (e.g., a room), with uniform velocity and parallel direction, to remove contaminants; it is part of a mobile cabinet or mount. Air is typically drawn from the environment into the system ...

Transoesophageal vascular ultrasound monitor

2 GUDID devices

A mains electricity (AC-powered) device intended to be used for monitoring cardiac output and/or fluid status through connection to a dedicated probe, which is placed in the oesophagus to measure blood flow in the descending aorta. It is based on measuring ...

Myograph

1 GUDID devices

A mains electricity (AC-powered) device designed for determining and recording the different phases of the intensity or velocity of a muscular contraction. It includes a sensor for detecting the displacement and/or force related to the muscle contraction an...
