Abstract: In a case where a balloon is broken and a body fluid reversely flows into a feed/discharge tube during a suction operation of a balloon control apparatus, a pump is stopped by operation-canceling section after passing of a preset predetermined time, and the suction operation of sucking the fluid into a bottle is canceled. Thereby, the amount of recovered liquid in the bottle is limited within a predetermined capacity. Thus, even in the case where the body fluid reversely flows into the feed/discharge tube, the body fluid does not overflow from the bottle, and the body liquid can properly recovered in the bottle.

Abstract: An endoscope image recording apparatus comprises a video endoscope having, at a forward end of an inserting section, an image pickup element, for image-picking-up the interior of a body cavity or the like, an image control unit for signal-processing a picture signal from the video endoscope, to generate an image signal, a portable IC memory card for recording the image signal from the image control unit as image data, a digital audio tape (DAT), a monitor for displaying the image signal from the image control unit or image data recorded on the IC memory card or the DATA, and indication means for indicating control operation to the image control unit. The IC memory card and the DAT tape record a serial number of the image, an INDEX image of the image, patient data, and image data. The IC memory card records an ID number of the DAT tape, while the DAT tape records an ID number of the IC memory card.
