Abstract: The dialysis apparatus in accordance with the present invention is provided with main piping connecting a blood inlet and a blood outlet, and having disposed therealong a blood pump, a dialyzer, and a venous-side chamber, in that order from the blood inlet side; and with a supplementary fluid supply mechanism, which is connected between the blood inlet and the blood pump through the medium of a branch pipe branching from the main piping; this apparatus is furthermore provided with a first clamp provided between the blood inlet and the blood pump of the main piping, a second clamp provided between the venous-side chamber and the blood outlet, and a third clamp provided on the branch pipe. In addition, by means of this dialysis apparatus, it is possible to reliably and easily return blood within the main piping of the dialysis apparatus to the body of the patient after the completion of blood dialysis.

Abstract: An apparatus for counting used medical cloths and measuring the quantity of liquid absorbed therein is disclosed. The apparatus comprises a hollow passage way for passing the medical cloths therethrough, an entrance portion for guiding the medical cloths to the passage, a pass detection sensor arranged in the passage for sensing the medical cloths, a weight sensor disposed at the bottom of the passage for sensing weight of dropped medical cloths, and a control unit for operating the output signals of the pass detection sensor and the weight sensor to output the number of dropped medical cloths and the weight of liquid absorbed therein. The control unit comprises a judging element for judging whether counting condition is normal or not according to the TSR of output signals of the sensors. The apparatus further comprises an alarm element for producing alarm signals when the judging element judges the condition abnormal.
