1. A biological signal processing apparatus comprising:
- a calculation controller which controls a process of generating an alarm, and which comprises;
a provider which provides state probability based upon one of;
a state probability table in which the state probability corresponds to, in advance, a value of a first biological signal; and
a calculation based on a deemed continuous value based on a measured first biological signal;
an acquirer which acquires a first biological signal in time series from a living body, and which acquires, from the provider, state probability in time series that corresponds to a value of the acquired first biological signal in time series; and
a determiner which calculates, by using a recurrence expression, present determination probability based on;
present state probability acquired by the acquirer; and
past determination probability, and which performs a determination whether a process is performed or not using the present determination probability, whereinthe calculation controller determines whether the alarm is currently on or not,when it is determined that the alarm is not currently on, (i) the determiner compares the calculated present determination probability with a first threshold to determine whether a process of generating an alarm is performed or not, and (ii) when the determiner determines to generate the alarm, the calculation controller initiates generation of the alarm and an alarm generation flag is set; and
when it is determined that the alarm is currently on, (i) the determiner compares the calculated present determination probability with a second threshold to determine whether a process of stopping the alarm is performed or not, and (ii) when the determiner determines to stop the alarm, the calculation controller initiates stoppage of the alarm and the alarm generation flag is reset.

Abstract
A biological signal processing apparatus includes: a provider which provides state probability which corresponds to a value of a first biological signal; an acquirer which acquires a first biological signal in time series from a living body and which acquires state probability in time series which corresponds to a value of the acquired first biological signal from the provider; and a determiner which acquires determination probability based on the state probability acquired by the acquirer and which performs determination whether a process is performed or not by using the determination probability.

6. A method of controlling a medical apparatus, the method comprising:
-
acquiring a first biological signal in time series from a living body, and acquiring state probability in time series that corresponds to a value of the acquired first biological signal in time series, based upon one of;
a state probability table in which the state probability corresponds to, in advance, a value of a first biological signal; and
a calculation based on a deemed continuous value based on a measured first biological signal;calculating, by using a recurrence expression, present determination probability based on;
present state probability of the acquired state probability; and
past determination probability;determining whether an alarm is currently on or not; when it is determined that the alarm is not currently on, (i) comparing the calculated present determination probability with a first threshold to determine whether a process of generating an alarm is performed or not and (ii) when it is determined to generate the alarm, initiating generation of the alarm and setting an alarm generation flag; and when it is determined that the alarm is currently on, (i) comparing the calculated present determination probability with a second threshold to determine whether a process of stopping the alarm is performed or not and (ii) when it is determined to stop the alarm, initiating stoppage of the alarm and resetting the alarm generation flag. - View Dependent Claims (7, 8, 9, 10)
