Abstract: PROBLEM TO BE SOLVED: To prevent chemical for sticking to the inside of a protection cylinder by mounting an adapter made of material having a form achieving partitioning effect and such characteristics that powder does not stick thereto and moisture is not absorbed therein. SOLUTION: To an end of charging cylinder 1 of a protection cylinder 5, an adaper is fixed by means of a band 4 so that a charging port 2 is covered therewith. This adapter 3 is formed of a material to which powdery medicines are hard to stick and which does not absorb moisture. Through the adaper 3, to shut out air flow to the inside of the cylinder 5, the speed of air thereinto is weakened and thereby the force of air applied to the powdery medicines dropping inside of it is weakened. Accordingly, a powdery medicine made to flow downstream or rotate is dreduced and the sticking thereof to the inside of the cylinder 5 is restrained.

Abstract: PURPOSE:To offer a method for hemodialysis and an apparatus therefor, under which removal of water can be done without causing such conditions as fall of blood pressure, headache, nausea or vomit, i.e., without giving any burden to a patient. CONSTITUTION:The targeted volume U (ml) of water removal in respect of a patient, the total time T (time) and the ultimate speed Ve of water removal (ml/time) are inputted into the arithmetic section 102 of the computer 100 by operating switches on the keyboard 20. The arithmetic section 102 calculates the speed V1 of water removal from time to time in accordance with the specified speed function f (t) of water removal containing a constant determined based upon the set targeted volume U (ml) of water removal, total time T (time) and ultimate speed Ve of water removal (ml/time). The speed V1 of water removal is converted into the control variable F1 for the water removal pump 12 at the arithmetic section 104 and its signal is inputted into the control unit 106 of the water removal pump 12. As a result, the rotational frequency of the driving motor M, for example, of the water removal pump 12 is controlled and the speed V of water removal of the dialyzator 1 is controlled accordingly.
