PERICARDIAL-LIQUID LEVEL CONTROL SYSTEM

摘要

Provided is a pericardial-liquid level control system with which a good viewing field can be ensured for an endoscope image without causing cardiac tamponade. A pericardial-liquid level control system is employed, including a sheath that is inserted into the pericardium; pumps that supply and expel liquid to and from the sheath; electrocardiogram electrodes that detect electrocardiographic information; and a pump control device that, in synchronization with the electrocardiographic information detected by the electrocardiogram electrodes, controls the pumps so that the liquid is supplied to the pericardium via the sheath during contraction of the heart and the liquid is expelled from the pericardium via the sheath during expansion of the heart.

1. A pericardial-liquid level control system comprising:
a pipe that is inserted into the pericardium; a pump that supplies and expels liquid to and from the pipe; an electrocardiographic-information detecting portion that detects electrocardiographic information; and a controlling portion that, in synchronization with the electrocardiographic information detected by the electrocardiographic-information detecting portion, controls the pump so that the liquid is supplied to the pericardium via the pipe during contraction of the heart and the liquid is expelled from the pericardium via the pipe during expansion of the heart.
