Abstract

An alarm notification apparatus includes an event detector for monitoring vital information of a body, such as a blood pressure and electrocardiogram, to check whether an anomalous event has occurred to the body. A reliability evaluator evaluates reliability of a result of detection of the anomalous event in the event detector. A notifier selects at least one addressee according to the reliability among plural predetermined addressees, and notifies the selected addressee of occurrence of the anomalous event. Preferably, a storage area is used for storing error log data expressing a false detection of an anomalous event in spite of non-occurrence of an anomalous event. Assuming that the event detector detects the anomalous event, the reliability evaluator obtains the reliability according to the error log data. Thus, it is possible to reduce influence of the false detection due to measurement artifact.

First claim

What is claimed is:

1. An alarm notification apparatus comprising:
a processor configured to perform the functions of:
monitoring vital information of a patient body, to check whether an anomalous event has occurred to said patient body;
evaluating reliability of a result of detection of said anomalous event in said monitoring vital information function; and
selecting at least one addressee according to said reliability among plural predetermined addressees, and notifying said selected addressee of occurrence of said anomalous event; and

an error storage for storing error log data indicating a false detection when the anomalous event has not actually occurred, but where the monitoring vital information function indicates occurrence of the anomalous event,
wherein in a case where said monitoring vital information function detects said anomalous event, said evaluating reliability function obtains said reliability according to said error log data,
wherein said monitoring vital information function outputs medical event record data, and
wherein said evaluating reliability function acquires degree of coincidence between said medical event record data and said error log data recorded previously by comparison thereof, sets said reliability higher according to lowness of said degree of coincidence, and sets said reliability lower according to highness of said degree of coincidence.

2. The alarm notification apparatus as defined in claim 1 , wherein a reference data storage area is used for storing reference range data of a reference range of said vital information;
wherein in a case where said vital information from said patient body becomes beyond said reference range, said monitoring vital information function detects said occurrence of said anomalous event to the patient body.

3. The alarm notification apparatus as defined in claim 1 , wherein said patient body is of a patient hospitalized in a hospital facility.

4. The alarm notification apparatus as defined in claim 1 , wherein said plural addressees include first and second addressees;
said notifying function further performs notification to said first addressee in a case where said reliability is lower than a predetermined threshold for recognition, and performs notification to said first and second addressees in a case where said reliability is equal to or higher than said threshold.

5. The alarm notification apparatus as defined in claim 4 , wherein said first addressee is an on-site user present in a hospital facility, and said second addressee is an off-site user absent from said hospital facility.

6. The alarm notification apparatus as defined in claim 5 , the processor further configured to check whether a user terminal apparatus used by each one of said plural predetermined addressees is on-line with a communication network of said hospital facility, to judge that one of said plural predetermined addressees is said on-site user in a case where said user terminal apparatus is on-line with said communication network, and to judge that another one of said plural predetermined addressees is said off-site user in a case where said user terminal apparatus is off-line from said communication network.

7. The alarm notification apparatus as defined in claim 5 , the processor further configured to acquire a current location of each one of said plural predetermined addressees from a user terminal apparatus used by each one of said plural predetermined addressees, to judge that one of said plural predetermined addressees is said on-site user in a case where said current location is inside said hospital facility, and to judge that another one of said plural predetermined addressees is said off-site user in a case where said current location is outside said hospital facility.

8. The alarm notification apparatus as defined in claim 4 , wherein said first and second addressees are medical staff members, and said second addressee is different from said first addressee in a professional category for a medical service to the patient body.

9. The alarm notification apparatus as defined in claim 1 , wherein said vital information is information of at least one of a blood pressure, electrocardiogram, heart rate, respiration rate and body temperature.

10. An alarm notification system including a diagnostic measurement apparatus for measuring vital information of a patient body, and an alarm notification apparatus for notifying occurrence of an anomalous event in said patient body upon said occurrence thereof according to said vital information of said patient body input by said diagnostic measurement apparatus, said alarm notification system comprising:
said alarm notification apparatus including:
a processor configured to perform functions of:
monitoring said vital information of said patient body, to check whether said anomalous event has occurred to said patient body;
evaluating reliability of a result of detection of said anomalous event in a resulting from the monitoring of vital information; and
selecting at least one addressee according to said reliability among plural predetermined addressees, and notifying said selected addressee of said occurrence of said anomalous event; and
said alarm notification apparatus further comprising an error storage for storing error log data indicating a false detection when the anomalous event has not actually occurred, but where the monitoring of vital information indicates occurrence of the anomalous event,
wherein in a case where said monitoring of vital information detects said anomalous event, said monitoring vital information function further obtains said reliability according to said error log data,
wherein said monitoring vital information function outputs medical event record data, and
wherein said evaluating reliability function acquires degree of coincidence between said medical event record data and said error log data recorded previously by comparison thereof, sets said reliability higher according to lowness of said degree of coincidence, and sets said reliability lower according to highness of said degree of coincidence.

11. An alarm notification method comprising steps of:
monitoring vital information of a patient body, to check whether an anomalous event has occurred to said patient body;
evaluating reliability of a result of detection of said anomalous event in said event checking step; and
selecting at least one addressee according to said reliability among plural predetermined addressees, to notify said selected addressee of occurrence of said anomalous event said method further comprising: storing error log data indicating a false detection when the anomalous event has not actually occurred, but where the monitoring vital information step indicates occurrence of the anomalous event;
wherein in a case where said monitoring vital information step detects said anomalous event, said evaluating reliability step obtains said reliability according to said error log data, and
wherein said monitoring vital information step further outputs medical event record data;
said evaluating reliability step acquires degree of coincidence between said medical event record data and said error log data recorded previously by comparison thereof, sets said reliability higher according to lowness of said degree of coincidence, and sets said reliability lower according to highness of said degree of coincidence.
