Fiber oxygen

Fig. 4. Primary liver cells are cultivated on the exterior surfaces of semipermeable capillary hollow fiber membranes. Medium is perfused through the extrafiber space. Through the fibers oxygen supply is supported...

In the case where the blood flow is laminar, as within hollow-fiber oxygenators, the rates of blood oxygenation can be predicted on a theoretical basis. Due to the shape of the oxyhemoglobin dissociation curve and the fact that the oxygen partial...

A commercial nitrogen enrichment system is illustrated in Fig. 17. Hollow-fiber membrane modules are connected to a compressed air feed at 70-150 psi. The feed in usually to the bore side of the hollow fibers. Oxygen (and water vapor that may be present) permeate out of the fiber into the shell and exit at low pressure. Dry, nitrogen-enriched air... 

Vibratory mechanism was one more interesting technique for reducing fouling negative effect. Vibrations can be apphed to flat sheet membrane modules, but many researchers tested the technique on performance of hollow fibers for different separation processes [3, 136]. One example of construction is shown in Fig. 9.10 [136] to assess the effect of axial membrane vibrations on mass transfer in a hollow fiber oxygenator. 

Flammability Test. Flammability of the samples was evaluated by two methods using cotton fabrics. Cotton fabrics were treated in the same way as cotton fibers. Oxygen index of the samples was measured according to the JIS K 7201 procedure. Another method... 

Application of optical fiber oxygen sensor in coal mines... 

The system is composed of the gas chamber (probe) and the monitor, by employing optic fiber between them to provide a remote and on-line measurement. The oxygen monitoring unit is often placed in a control room. The probe is installed at the monitored location. The fiber cable is used to transmit signals between the probe and monitoring unit. The passive probe makes it more suitable for being deployed in the hazard environment. The monitor unit can be connected up to multiple optic fiber oxygen probes. 

We designed an optic fiber oxygen sensor based on DEB laser wavelength scanning and spectrum absorption technique. With the use of the optical fiber links between monitor and sensor header, the system can provide remote and online monitor information. Since the sensor head is made without any active electrical components, it is intrinsically safe when used in the hazard environment such as coal mines. The oxygen sensor works in...
