Abstract

An endoscope apparatus including a connector included in an endoscope and connected to an endoscope connection portion of a video processor, a fluid feeding apparatus including a tube configured to transmit fluid to the endoscope, a connection detector configured to detect a connection state of the tube with the connector of the endoscope, a control unit configured to detect an ON/OFF state of a power source of the fluid feeding apparatus, determine an abnormality exists when the connection detector detects that the tube is in a disconnected state with the connector of the endoscope and the power source of the fluid feeding apparatus is detected to be in an ON state, and output a notification of the determined abnormality, and a display configured to display the notification of the abnormality outputted by the control unit.

First claim

What is claimed is:

1. An endoscopic apparatus comprising:
a connector included in an endoscope and connected to an endoscope connection portion of a video processor;
a fluid feeding apparatus including a tube configured to transmit fluid to the endoscope;
a connection detector configured to detect a connection state of the tube with the connector of the endo scope;
a control processor configured to:
detect an ON/OFF state of a power source of the fluid feeding apparatus;
determine an abnormality exists when the connection detector detects that the tube is in a disconnected state with the connector of the endoscope and the power source of the fluid feeding apparatus is detected to be in an ON state; and
output a notification of the determined abnormality; and

a display configured to display the notification of the abnormality outputted by the control processor.

2. The endoscopic apparatus according to claim 1 , wherein the control processor is configured to transmit a prohibition signal to the fluid feeding apparatus prohibiting transmission of the fluid to the endoscope when the tube is detected to be disconnected from the connector and the power source of the fluid feeding apparatus is in the ON state.

3. The endoscopic apparatus according to claim 1 , wherein the control processor is configured to:
determine a type of the endoscope, and
output the notification of the abnormality based on the determined type of the endoscope, the detected connection state of the tube with the connector of the endoscope, and the detected ON/OFF state of the power source of the fluid feeding apparatus.

4. The endoscopic apparatus according to claim 3 , wherein the control processor is configured to transmit a prohibition signal to the fluid feeding apparatus prohibiting transmission of the fluid to the endoscope when the tube is determined to be unable to be connected to the connector based on the determined type of the endoscope and determining that the power source of the fluid feeding apparatus is in an ON state.

5. The endoscopic apparatus according to claim 1 , wherein the control processor is configured to:
determine a type of the endoscope, and
transmit a prohibition signal to the fluid feeding apparatus prohibiting transmission of the fluid to the endoscope when the tube is determined to be unable to be connected to the connector based on the determined type of the endoscope and determining that the power source of the fluid feeding apparatus is in an ON state.

6. The endoscopic apparatus according to claim 1 , further comprising memory including endoscope identification information, wherein the control processor is configured to determine a type of the endoscope based on the endoscope information stored in the memory.

7. The endoscopic apparatus according to claim 6 , wherein the control processor is configured to output the notification of the abnormality based on the determined type of the endoscope, detecting that the tube is connected to the connector and determining that the power source of the fluid feeding apparatus is in an OFF state.

8. A video processor to which an endoscope and a water feeding apparatus configured to supply fluid to the endoscope are connected, the video processor comprising a control processor configured to communicate with the endoscope and the water feeding apparatus, the control processor being configured to:
acquire (i) information indicating whether a tube of the endoscope configured to supply the fluid from the water feeding apparatus is in a connected state or a disconnected state with respect to the endoscope and (ii) information on whether a power source of the water feeding apparatus is in an ON state or an OFF state,
determine an abnormality exists when the tube is in the disconnected state and the power source is in the ON state based on the acquired information, and
control a display to display a notification in response to determine that the abnormality exists.

9. An activation method of an endoscopic apparatus, the endoscopic apparatus including a connector included in an endoscope and connected to an endoscope connection portion of a video processor, and a fluid feeding apparatus including a tube connected to the connector and configured to supply fluid to the endoscope, the activation method comprising:
a step of transmitting the fluid to the endoscope via the tube by the fluid feeding apparatus;
a step of detecting a connection state of the tube with the connector by a connection detector;
a step of detecting an ON/OFF state of a power source of the fluid feeding apparatus by a control processor;
a step of determining an abnormality exists when the connection detector detects that the tube is in a disconnected state with the connector of the endoscope and the power source of the fluid feeding apparatus is detected to be in an ON state; and
a step of outputting a notification of the determined abnormality.
