1. A safe nursing system comprising:
- a control unit programmed to monitor a movement of a patient on a bed, the control unit including;
an alert level setting unit that sets, for each patient, a correspondence relationship between a plurality of types of predetermined movements and a plurality of alert levels including “
warning,”
“
caution,” and
“
normal alert”
based on conditions;
a calculation unit that calculates a value of a predetermined index used to determine a predetermined movement of the patient;
a setting unit that sets a predetermined condition to determine the predetermined movement;
a determination unit that determines the predetermined movement based on the value calculated by the calculation unit and the predetermined condition set by the setting unit; and
an output unit that outputs information indicating that the patient has performed the predetermined movement at the alert level indicated by the correspondence relationship set for the patient by the alert level setting unit in accordance with the predetermined movement, under the condition that the determination unit has determined that the predetermined movement has been performed; and
an image capturing unit disposed in a position from which an image including a side of a top surface of the bed can be captured;
whereinthe control unit further includes an image capturing control unit that obtains image data captured by the image capturing unit;
the calculation unit specifies feature points in an image of the patient in the image data obtained by the image capturing control unit and calculates a value of the predetermined index of the specified feature points;
the setting unit sets the predetermined condition based on a region of the bed in the image data obtained by the image capturing control unit;
the control unit further includes a caregiver determination unit that determines whether or not a caregiver is present based on the image data obtained by the image capturing control unit; and
the alert level setting unit changes, in a case where the caregiver determination unit determines that a caregiver is present, the correspondence relationship so as to lower, but not cancel, the alert level from “
warning”
to “
caution”
or from “
caution”
to “
normal alert”
for each predetermined movement indicated by the set correspondence relationship.

Abstract
A safe nursing system includes a control unit and monitors movement of a patient on a bed. The control unit sets, for each patient, a correspondence relationship between a plurality of types of predetermined movements and a plurality of alert levels based on conditions; calculates a value of a predetermined index used to determine a predetermined movement of the patient; sets a predetermined condition to determine the predetermined movement; determines the predetermined movement based on the calculated value and the set predetermined condition; and outputs information indicating that the patient has performed the predetermined movement at the alert level indicated by the correspondence relationship set for the patient in accordance with the predetermined movement, under the condition that the predetermined movement has been determined to have been performed. It is possible to give a notification to a caregiver based on the condition of each patient.

7. A control method for controlling a safe nursing system that includes a control unit programmed to monitor a movement of a patient on a bed, the method comprising the steps, executed by the control unit, of:
-
setting, for each patient, a correspondence relationship between a plurality of types of predetermined movements and a plurality of alert levels including “
warning,”
“
caution,” and
“
normal alert”
based on conditions;calculating a value of a predetermined index used to determine a predetermined movement of the patient; setting a predetermined condition to determine the predetermined movement; determining the predetermined movement based on the calculated value and the set predetermined condition; outputting information indicating that the patient has performed the predetermined movement at the alert level indicated by the correspondence relationship set for the patient in accordance with the predetermined movement, under the condition that the predetermined movement has been determined to have been performed; determining whether or not a caregiver is present based on image data obtained by an image capturing control unit; and in a case where the caregiver is present, lowering, but not canceling, the alert level from “
warning”
to “
caution”
or from “
caution”
to “
normal alert”
for each predetermined movement indicated by the set correspondence relationship. - View Dependent Claims (9)
