摘要:
A system of analysis, comprising means for the withdrawal of blood from a patient or other source (1) and for the conducting of the same past a measuring electrode (5) or the like and means for the feed of a diluting and/or anticoagulant fluid (13) to a point near the said source (1). The system is characterized in that the said means comprise one or more pumps (10, 14), with the help of which blood samples can be drawn intermittently, and which in between are adapted to feed some of the said fluid to the said point near the sampling point. The system is intended in particular for the measurement of potassium, calcium and sodium in the blood, but may also be used for the measurement of other substances, e g glucose in connection with diabetes.
摘要:
System for controlling a medical treatment, for example dialysis, using a preferably heated treatment fluid, comprising means (18,28) for controlling the flow of the fluid through the system and means (36,37) for connecting the system to a treatment device, for example a dialyzer (33), whereby disinfection and/or sterilization and/or other cleansing of the system is effected with the aid of a liquid which is made to flow along the same path as the treatment fluid, except that it is diverted past the treatment device by means of a so called by-pass arrangement (38-41 and/or 34,35). The system according to the invention is characterized by means for connecting a cartridge or other vessel (1' ,1'' or 1''') to a conduit (1,12,17) in the system, wherein the cartridge or vessel contains a soluble concentrate in liquid or powder form, preferably powder form, which achieves or at least aids the said cleansing, and by means (1a) for supplying water or another solvent to said conduit (1) to flow through and dissolve the concentrate.

摘要:
Medical treatment apparatus, such as a dialysis monitor, comprising a vessel (1',1'',1''') containing a cleaning agent, such as citric acid, connected to a supply means (1a) for a solvent, for introducing the solvent into the vessel (1',1'',1''') and further to the medical treatment apparatus for disinfection and/or sterilization thereof. The medical treatment apparatus comprises a recirculation circuit including a heating device (2) for heating the cleaning fluid.
