Abstract

For each biological information, a caution level range and a warning level range as to the biological information value are stored. When the acquired biological information value of the biological information of a patient falls within the caution level range, a notice of the status of the patient is given to a first notice destination. When the aforementioned biological information value falls within the warning level range, the notice of the status of the patient is given to a second notice destination. Thus, by switching the notice destinations based on the status of the patient, it is possible to provide a patient status notification device or the like that can appropriately and promptly perform notification.

Claims

1. A system for monitoring patient status, comprising:

at least one sensor that automatically and continuously acquires biological data from a patient;

a plurality of destination terminal devices; and

a controller configured to;

continuously receive biological data from the at least one sensor;

compare currently received biological data with one or more threshold values;

trigger a first alarm message at a first destination terminal device if the currently received biological data is determined to be outside of a first range based on the comparison with the one or more threshold values;

trigger a second alarm message at a second destination terminal device if the currently received biological data is determined to be outside of a second range based on the comparison with the one or more threshold values;

wherein the second range includes the first range, and the first destination terminal device is different from the second destination terminal device,

wherein the one or more threshold values compared with the received biological data are selected based on an associated patient identifier, a type of the currently received biological data and a notice setting in an alarm notice level table.

2. The system of claim 1, further comprising

a memory having stored therein the alarm notice level table identifying how notice of an alarm message should be given for a particular patient.

3. The system of claim 1, wherein each of the plurality of destination terminal devices are associated with a specific medical professional or a team of medical professionals assigned to care for the patient.

4. The system of claim 1, wherein the plurality of destination terminal devices includes one or more portable devices, each associated with a specific physician or nurse assigned to care for the patient.

5. The system of claim 1, wherein the controller is further configured to allow an authorized medical professional to update or adjust the one or more threshold values.

6. The system of claim 1, wherein the first and second alarm messages each include a patient identifier, and the biological data that triggered the alarm message.

7. The system of claim 6, wherein the first and second alarm messages each further include a response status indicating the medical professional who will handle each alarm message.

8. The system of claim 1, wherein the controller is further configured to

trigger a second notification of the first alarm message, if the controller determines that a predefined period of time has elapsed from triggering the first alarm message.

9. A patient status monitoring device, comprising:

a memory; and

a controller configured to

communicate with a plurality of destination terminal devices;

continuously receive biological data from at least one sensor;

compare currently received biological data with one or more threshold values;

trigger a first alarm message at a first destination terminal device if the currently received biological data is determined to be outside of a first range based on the comparison with the one or more threshold values; and

trigger a second alarm message at a second destination terminal device if the currently received biological data is determined to be outside of a second range based on the comparison with the one or more threshold values;

wherein the second range includes the first range, and the first destination terminal device is different from the second destination terminal device,

wherein the one or more threshold values compared with the received biological data are selected based on an associated patient identifier, a type of the currently received biological data and a notice setting in an alarm notice level table.

10. The device of claim 9, wherein

the memory has stored therein an alarm notice level table identifying how notice of an alarm message should be given for a particular patient, and.

11. The device of claim 9, wherein each of the plurality of destination terminal devices are associated with a specific medical professional or a team of medical professionals assigned to care for the patient.

12. The device of claim 9, wherein the plurality of destination terminals includes one or more portable devices, each associated to a specific physician or nurse assigned to care for the patient.

13. The device of claim 9, wherein the controller is further configured to allow an authorized medical professional to update or adjust the plurality of stored threshold values associated with each type of biological data.

14. The device of claim 9, wherein the first and second alarm messages each include a patient identifier, and the biological data that triggered the alarm message.

15. The device of claim 14, wherein the first and second alarm messages each further include a response status indicating the medical professional who will handle each message.

16. The device of claim 9, wherein the controller is further configured to

trigger a second notification of the first alarm message, if the controller determines that a predefined period of time has elapsed from triggering the first alarm message.

17. A non-transitory computer readable medium having stored thereon instructions that when executed by a processor, cause the processor to perform the steps of

communicating with a plurality of destination terminal devices;

continuously receiving biological data from at least one sensor;

comparing currently received biological data with one or more threshold values;

triggering a first alarm message at a first destination terminal device if the currently received biological data is determined to be outside of a first range based on the comparison with the one or more threshold values; and

triggering a second alarm message, at a second destination terminal device if the currently received biological data is determined to be outside of a second range based on the comparison with the one or more threshold values;

wherein the second range includes the first range, and the first destination terminal device is different from the second destination terminal device,

wherein the one or more threshold values compared with the received biological data are selected based on an associated patient identifier, a type of the currently received biological data and a notice setting in an alarm notice level table.
