 |
BOM-L1W |
||
 |
【New function】 |
|||
 Type W has two detection system, and the two detectors can be put on tissue freely. The detected power(level) is dependent on the distance between the incidence and detection point, and the level has to be changed for matching the instrument. WGC dials of the back panel are used to adjust the detected levels of two detectors independently. |
||||
| |
||||
 |
The arbitrary value obtained by each detector can be selected by using
this switch. Detector 1, Detector 2 and Detector 2 minus Detector 1 can be selected |
|||
 |
||||
 |
Type W detector has two detection heads. One is for shallow and the other
is for deep sampling. |
|||
 |
||||
 |
The holder is used for stable measurement. The distance between the incidence
and detection point(receiving) can be set freely, and the light from outside is shut. This holder is soft and a special adhesive gel sheet is available. |
 The example of measurement |
||
| 【Feature】 ・The combination of the sensor of send,Received 1, and Received 2 can estimate the oxygen-ized state of the organization blood of specific depth. ・by taking the difference of 2 Received, it is markedly alike, and is mitigated and the more highly sensitive measurement of offset was attained ・Not the amount of change like before but absolute quantity can be outputted. ・The degree of oxygen saturation which evaluates the oxygen-ized state of organization blood by % can be outputted. ・Since the semiconductor laser is used, high measurement of a S/N ratio is possible. ・Stable luminescence system It is good that operation processing speed makes it quick much more. It became ability. ・Since it is a small probe, fixation is easy. |
| 【Principle】 ・BOM-L1 series irradiates in an organization 2-3 kinds of laser light from which wavelength differs, catches the light absorbed and scattered about by Received, and carries out operation processing. ・The optical absorption coefficient of oxygen-ized hemoglobin and deoxidization-ized hemoglobin changes with wavelength of light. This principle is used and the oxygen-ized hemoglobin under living body organization, deoxidization-ized hemoglobin, and the degree of oxygen saturation are calculated. ・Although measurement depth calls at an organization, it becomes almost of the same grade as an optical fiber probe and the distance between detectors. |
