Dialysis equipment, monitoring method of entry of air into the dialysis fluid, and how to perform monitoring and pressure retention test of entry of air into the dialysate
A dialysis liquid circuit with conduits for conducting dialysis liquid and elements for detecting air in the dialysis liquid. The elements includes at least one gas sensor traversed continuously by the dialysis liquid, which is configured such that it measures at least one property of the dialysis liquid which depends on the presence of air bubbles in the dialysis liquid, and which is arranged downstream of a region to be monitored of the dialysis liquid circuit. During operation of the dialysis liquid circuit a negative pressure exists with respect to atmospheric pressure, and the elements includes an evaluation unit which is connected with the gas sensor and which is configured such that the property measured by means of the gas sensor is evaluated with regard to the presence of air bubbles in the dialysis liquid.
