LIQUOR PRESSURE MECHANOTRONIC TRANSDUCER Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: device has manotron with membrane and measuring reservoir having an opening with a complex shape bushing mounted inside. One of the bushing ends has spheric surface and the other one is provided with cylindric nipple connected with syringe needle by means of a T-joint. The nipple has a hole in the lateral surface for a leakage-proof plug to be inserted. Flexible membrane is drawn up over the spheric area of the bushing, bushing membrane stiffness being 50 time as small as that of the manotron membrane. The spheric portion of the complex shape bushing can be made in the form of a disk with a nipple. EFFECT: enhanced accuracy in measuring cerebrospinal fluid pressure. 2 cl, 1 dwg
