2. Ultrasonic flow meter - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_flow_meter

   Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...

3. ShuntCheck - Wikipedia

   en.wikipedia.org/wiki/ShuntCheck

   ShuntCheck is a non-invasive diagnostic medical device which detects flow in the cerebral shunts of hydrocephalus patients. Neurosurgeons can use ShuntCheck flow results along with other diagnostic tests to assess shunt function and malfunction. [1]

4. Photoplethysmogram - Wikipedia

   en.wikipedia.org/wiki/Photoplethysmogram

   A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. [1][2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3] A conventional pulse oximeter monitors the perfusion of blood to ...

   Ultrasonic transducer. A curvilinear array ultrasonic transducer for use in medical ultrasonography. Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters ...

6. Bioinstrumentation - Wikipedia

   en.wikipedia.org/wiki/Bioinstrumentation

   Bioinstrumentation or Biomedical Instrumentation is an application of biomedical engineering which focuses on development of devices and mechanics used to measure, evaluate, and treat biological systems. The goal of biomedical instrumentation focuses on the use of multiple sensors to monitor physiological characteristics of a human or animal ...

7. Oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Oxygen_sensor

   Oxygen sensor. An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter ...
