Apparatus for artificial kidney, quality evaluating device for dialyzing fluid and dialyzing means using the same, and fluid circuit

An apparatus for an artificial kidney comprising:

• a first fluid circuit for introducing body fluid of a living body into dialyzing means;
• dialyzing means for removing waste products from the body fluid;
• a second fluid circuit for recovering and returning the body fluid to the living body;
• and
• oxygen supplying means for increasing partial pressure of oxygen in arterial blood of the living body,
• further comprising a measurement monitor for continuously measuring nitric oxide (NO) or nitric oxide oxydant (NOx) of the body fluid in said first fluid circuit and/or said second fluid circuit to detect a possibility of hypotension or hypoxia associated with artificial dialysis, and display means for displaying the result of comparison between a measurement value measured by said measurement monitor and a desired value.

A quality evaluating device for dialyzing comprising:

• a first fluid circuit for introducing body fluid into dialyzing means;
• dialyzing means for removing waste products from the body fluid;
• and
• a second fluid circuit for recovering the body fluid, further comprising a measurement monitor for continuously measuring nitric oxide (NO) or nitric oxide oxydant (NOx) of the body fluid in said first fluid circuit and/or said second fluid circuit and by being capable of evaluating the quality of said dialyzing means.
