Claim 0:
1. A blood purification system comprising:
a blood purification apparatus that gives blood purification treatment to a patient, the blood purification apparatus comprising:
a blood pump;
an ultrafiltration pump;
a sensor configured to sense a sensed parameter; and
a speaker or an external indicator lamp;

a managing apparatus that communicates with the blood purification apparatus in such a manner as to transmit and receive information on the blood purification treatment to and from the blood purification apparatus, the managing apparatus comprising:
a server including:
a communication module;
a storage unit that stores the information, including the sensed parameter, on the blood purification treatment in a time course with progress of the blood purification treatment and accumulates the information as a history for each blood purification treatment session so that the history of each the blood purification treatment session is one of a plurality of histories stored in the storage unit, wherein the information is transmitted to the storage unit by the communication module;
an extracting unit that searches the plurality of histories of the patient accumulated in the storage unit and extracts, as reference histories, a plurality of reference histories each including any events having occurred during a current session of blood purification treatment or a plurality of histories each including the sensed parameter approximate to the sensed parameter observed during the current session of blood purification treatment;
a list-creating unit that creates a list of the plurality of reference histories extracted by the extracting unit, wherein the list-creating unit sets an order of the list in accordance with a degree of approximation in a timing of occurrence of the events having occurred unsteadily in the blood purification treatment or the sensed parameter related to the blood purification treatment; and
a web-application module; and

a client personal computer (PC) comprising:
a display unit provided to the blood purification apparatus or to the managing apparatus and that displays the information on the blood purification treatment;
a client application comprising:
a display control unit that controls the list created by the list-creating unit to be displayed on the display unit; and

wherein when any of the plurality of reference histories displayed in the list is selected and input, the reference history selected is displayed with the information on the current session of blood purification treatment;

wherein the history includes the events having occurred unsteadily or suddenly during the blood purification treatment or the sensed parameter related to the blood purification treatment and that changes with time during the blood purification treatment;
wherein the history includes the sensed parameter;
wherein a setting parameter is provided to the blood pump or the ultrafiltration pump based upon the sensed parameter to change operation of the blood pump or the ultrafiltration pump;
wherein the extracting unit extracts a history and approximates a specific parameter value of a current blood purification treatment over a predetermined period of time relative to the specific parameter value stored in the storage unit, creates a list by the list-creating unit, and sends the list to the client PC via the client application and the web-application module;
wherein the client PC controls the display unit and the display unit displays the list transmitted from the server by the display control unit in the current session of blood purification treatment;
wherein the events having occurred unsteadily includes warnings or notifications generated by the blood purification apparatus and a log of operations performed in response to the warnings or the notifications,
wherein, when an abnormality occurs in the blood purification apparatus, the speaker or the external indicator lamp generate an alarm, the warnings, or the notifications and the log of operations performed in response to the warnings or the notifications are extracted by searching the history and are displayed on the display unit by the display control units;
wherein the list-creating unit that automatically creates a warning list at the timing of the occurrence of the events having occurred unsteadily in the blood purification treatment, and the warning list is displayed on the display unit with the blood purification treatment; and
wherein the warning list highlights a desired event to a medical worker so that the medical work can track the desired event in advance of any abnormality in a transition of a parameter and prepare in advance to treat the desired event and the display control unit displays parameters related to the current session of the blood purification treatment as a graph over a progress of time and the display control unit displays a log of actions performed in response to the warnings or the notifications as an event bar with the graph so that the actions performed are displayed with the progress of the time.
