    CAUTION 1. Turn the laser switch on after the probe was connected. 2. Do not see the laser light through a lens or an optical instrument.

  • Page 4: Summary

    1. Summary This laser tissue blood flowmeter, OMEGAFLO FLO-C1, is useful instrument for measuring tissue blood flow in skin, brain, internal organs, etc. for animals. FLO-C1 can measure blood flow continuously and non-invasively, compared to H2 and Xe clearance method , and is used widely from in fundamental research to in clinical applications.

  • Page 6 2) Part Functions ① Indicator This LED indicator shows the measurement value of one of tissue blood flow parameters selected by "Parameter selection switch ②". Also, it shows the output mode selected by Mode switch ③. FLO-C1 measures three blood flow parameters, FLOW, MASS and VEL. FLOW, MASS and VEL.
  • Page 7 ④ Laser switch Laser power is operated by this switch. Press this switch for ON and the red light glows. ! Optical connectors Optical connectors to connect a probe for FLO-C1. The plugs of standard probes are not specified by RED and BLACK. The plugs of a special probe are specified by RED and BLACK.
  • Page 8 ⑦ Handle Use this handle for carrying FLO-C1. ⑧ Time constant switch The time-constant of output can be selected by this switch. FLO-C1 has three states of the time-constant, 0.1(sec), 1(sec) and 3(sec). ⑨ Output 1 The output of three parameters. The voltage of the three parameters is 0-10(V).

    4. Example of Measurement 1) Probe set up (1) Prepare FLO-C1 and the recorder following "3. Connection to Recorder and Operation". (page 6-8) (2) Set the time-constant switch on the rear panel at 0.1 sec . (3) Fix a probe on tissue under study like the figure below. Confirm "REFLEX"...

  • Page 14: Theory

    5. Theory 1) Laser tissue blood flowmetry As laser light illuminates a tissue containing erythrocytes (red blood cells), the light is diffused by the tissue. Generally, the volume fraction of the erythrocytes in the tissue is small ; therefore, most of the photons are only scattered by static tissue elements and, in the case of short optical path length, a small number of photons are scattered by the erythrocytes once, or at most a few times, during the scattering process.

    6. Handling and Cautions 1) Pay attention to the next matters. (1) Keep FLO-C1 out of water. (2) Set FLO-C1 on the place where air pressure, temperature, humidity, wind, sunlight, dust, and air containing salt and sulfur do not cause bad condition. (3) Pay attention to inclination, vibration and shock.
  • Page 16 Pay attention to the next matters for probes. ① Do not scrub the tip of probes. ② Do not bend into a circle of under 10 mm radius. ③ Do not step on probes. ④ Keep the tip and plugs clean. ⑤...
  • Page 17 ② Set FLO-C1 on the place where air pressure, temperature, humidity, wind, sunlight, dust, and air containing salt and sulfur do not cause bad condition. ③ Pay attention to inclination, vibration and shock. ④ Keep FLO-C1 out of a storeroom of chemicals and the place where gas generates.
