Abstract

Object
Provided is an electromedical device control system and the like capable of improving the accuracy of determining a blocked state of a flow path.
Solving means
An electromedical device control system according to an embodiment of the present disclosure includes a determination unit that performs predetermined determination based on a pressure value of a fluid supplied to a flow path of an electromedical device, a pressure threshold set according to a setting value of a flow rate of the fluid, and an amount of change over time in the pressure value. The determination unit determines whether the amount of change over time in the pressure value is a positive value when determining that the pressure value is equal to or greater than the pressure threshold.

the determination unit performs control such that a predetermined handling operation is executed when determining that the time in which the pressure value is equal to or greater than the pressure threshold is equal to or greater than the time threshold, and the determination unit performs control such that the predetermined handling operation is not executed when determining that the time in which the pressure value is equal to or greater than the pressure threshold is less than the time threshold.

4 . The electromedical device control system according to claim 2 , wherein
the determination unit performs control such that the predetermined handling operation is not executed when determining that the pressure value is equal to or greater than the pressure threshold and determining that the amount of change over time in the pressure value is not a positive value.

5 . The electromedical device control system according to claim 2 , wherein
the predetermined handling operation includes at least one of an operation of giving a warning to an outside, an operation of stopping supply of the fluid, or an operation of stopping supply of electric power to the electromedical device.

6 . The electromedical device control system according to claim 2 , wherein
the predetermined handling operation includes a handling operation when it is determined that at least a part of the flow path is in a blocked state.

7 . The electromedical device control system according to claim 1 , wherein
the determination unit performs determination using the pressure value and the amount of change over time in the pressure value after a predetermined reduction process is executed on noise included in the pressure value.

8 . The electromedical device control system according to claim 1 , wherein
the pressure threshold is set such that an amount of increase in the pressure threshold is zero or greater when the setting value of the flow rate of the fluid increases, and the pressure threshold is set such that an amount of decrease in the pressure threshold is zero or greater when the setting value of the flow rate of the fluid decreases.

9 . The electromedical device control system according claim 1 , further comprising
a fluid supply unit configured to supply the fluid to the flow path of the electromedical device, wherein the fluid supply unit and the determination unit are provided in a single device.

10 . The electromedical device control system according to claim 1 , further comprising
a fluid supply unit configured to supply the fluid to the flow path of the electromedical device, wherein the fluid supply unit is provided in a fluid supply device, and the determination unit is provided in a power supply device separate from the fluid supply device.

11 . The electromedical device control system according to claim 1 , wherein
the electromedical device includes an irrigation mechanism configured to perform irrigation using the fluid.

12 . A method of controlling an electromedical device system, the method comprising:
performing predetermined determination based on a pressure value of a fluid supplied to a flow path of an electromedical device, a pressure threshold set according to a setting value of a flow rate of the fluid, and an amount of change over time in the pressure value, wherein the performing of the predetermined determination includes determining whether the amount of change over time in the pressure value is a positive value when determining that the pressure value is equal to or greater than the pressure threshold, and the performing of the predetermined determination includes determining whether a time in which the pressure value is equal to or greater than the pressure threshold is equal to or greater than a time threshold when determining that the pressure value is equal to or greater than the pressure threshold and determining that the amount of change over time in the pressure value is not a positive value.
