摘要:
To provide an optical module with optical elements having a collimator and filter functions arranged on the same substrate, and reducing a complicated alignment and obtaining an excellent optical coupling while securing actually sufficient amount of reflection attenuation. A plurality of wavelength selective filters 71 to 74 with different selective wavelengths are disposed on a substrate 50, so that reflected light reflected by a filter is sequentially made incident, and fiber collimators 101 to 106 combined of an optical fiber terminal with a coreless fiber attached to its tip end and a lens are disposed on an optical path of incident light made incident to a filter on the uppermost stream side, on an optical path of transmitted light transmitted through each filter, and on an optical path of reflected light by a filter on the lowermost stream side. Each fiber collimator is alternately disposed on one side and the other side of one substrate, and positioned so as to be placed in V-grooves 61 to 66 formed on the same plane on the substrate. All of the V-grooves are formed on the same plane, and at least one set of the fiber collimators having a relation of facing to each other through the filter on one side and the other side is disposed on the same axial line.

A collimator 111 for an input light, a collimator 112 for an output light, a collimator 113 for a branched light, a collimator 114 for an inserted light and a wavelength selecting filter 115 are provided on a common substrate 130, and mirrors 121 to 124 for correcting an optical path or prisms XXXX to XXXX capable of producing the same advantages are provided on the optical paths between the collimators 111 to 114 and the wavelength selecting filter 115 respectively. By adjusting the mirrors or prisms, the shift of the optical axis between the collimators is corrected.

A brain cooling device is provided to cool the brain sufficiently to the subcortical tissue in a short time. The device includes a cuff (3) capable of storing therein a cooled fluid and placeable in the esophagus (H1) of the patient (H) when inserted orally or transnasally. A tube (2) extends from the cuff (3) for infusing the fluid into the cuff (3) placed in the esophagus (H1) from outside the body of the patient H and discharging the fluid from the cuff (3). The cuff (3) has flexibility so as to inflate or deflate in response to infusion or discharge of the fluid and is configured in such a manner that when the fluid is infused therein while placed in the esophagus (H1), the cuff (3) that has been inflated comes into close contact with the inner wall (H4) of the esophagus (H1).

The present invention provides a bilirubin reducing means which can minimize a risk such as the onset of an infection or the occurrence of blood coagulation and can reduce physical, temporal and economical burdens imposed on a patient suffering from liver dysfunction. A bilirubin denaturating apparatus includes a dialyzing portion which has a dialyzing column for performing dialysis of blood using hollow fibers incorporated therein; an infusion supply portion which supplies an infusion used for dialysis in the dialyzing portion to the dialyzing portion; and a blood circulating portion which feeds blood to the dialyzing portion and returns the blood dialyzed by the dialyzing portion, wherein the dialyzing portion includes a radiation means which radiates green light to the hollow fibers, and the radiation means radiates the green light to the hollow fibers for converting fat-soluble bilirubin in the blood flowing in the inside of the hollow fibers into water-soluble bilirubin thus eluting the water-soluble bilirubin in the infusion.
