补冬摘要：1462009 Blood leakage detector BAXTER TRAVENOL LABORATORIES Inc 26 Feb 1975 [22 March 1974] 7967/75 Heading G1A Such a detector compris opaque thermally conductive block 12 with bore 13 cloly receiving transparent flow conduit 11, passages 14 perpendicular to conduit 11 and 15, which is clear, which interct at one end where light source 17 is mounted, photo-cells 20, 21 at their other ends and an alarm circuit responsive to the difference of light intensity reaching the photo-cells. Dialysate from an artificial kidney machine circulates through conduit 11. Lamp socket 16 is adjustably cured in bore 18 of aluminium block 12 by t screw 19. Photo-voltaic cells 20 and 21, such as silicone cells, are mounted ahead of identical filters 22, 23 of 550-560 nm corresponding to a condary absorption peak of haemoglobin. Retaining plate 24 has apertures 27, 28 for cell leads. Light obstructing calibrating screw 25 has locknut 26. The effective lengths of passages 14, 15 are the same. The heating effect of the lamps or of the dialysate affects photo-cells 20, 21 equally. Lamp 17 is at the focus of the lens equivalent to conduit 11 and its contents. Illumination flux in a solid angle of 25‹C reaches photo-cells 20, 21. Bulb 17 provides a high output from 540-570 nm. In the alarm circuit of Fig. 3 comparator amplifier 33 gives 1V output when V x > reference voltage V B and 17V when V x凉凉mv
