Latest Patents
One of Tachi's latest patents is a monitoring system for a medical pump. This system features a reversible operating body that compresses and expands a space for accommodating fluid. It includes suction and ejection ports that communicate via a no-return valve. The system is designed to inform users of abnormalities, such as stoppages or deviations from predetermined positions. Additionally, it measures the flow rate of blood ejected from an artificial heart by calculating the internal volume of the operating body from photographed images.
Another notable patent is an electrocardiographic measurement method for controlling an intra-aortic balloon. This method involves a pair of spaced electrodes placed inside the thoracic aorta near the heart. These electrodes sense R- and P-waves in an ECG signal. The electrodes are positioned to ensure that the R- and P-waves have the same magnitude, allowing for accurate predictions of the R-wave occurrence. The intra-aortic balloon is deflated at the predicted R-wave, enhancing the effectiveness of the procedure.
