| titleOfInvention | How to check shunt valve flow rate in ventricular shunt |
| abstract | (57) [Summary] [Purpose] The flow rate of the shunt valve of the ventricular shunt is checked while the ventricular shunt is embedded in the body. [Structure] In a ventricular shunt equipped with a ventricular catheter 12, a reservoir 10 with a curved dome 10a for measuring intracranial pressure, a shunt valve 15 and a perfusion catheter 16, a steady state reservoir internal pressure P 0 is measured, and then a flexible tube 13 is used. The time T 1 from when the shunt valve 15 is closed and the internal pressure of the reservoir 10 returns to P 0 is measured after the required amount of cerebrospinal fluid ΔV is discharged by the pump action that presses the curved dome 10a after the pressure is closed. Shunt valve 15 after T 1 time has passed Is opened and the time T 0 until the internal pressure of the reservoir returns to P 0 is measured, and the flow rate of the shunt valve 15 is checked from ΔV / T 0 . |
