Abstract
The invention relates to a device for detecting a malfunctioning of a valve/catheters assembly for shunting a cerebrospinal fluid or the like, characterized in that it comprises: a chamber (6) which is placed inside the said housing; a laminar canal (4), a sensor (7) for measuring a pressure in the said chamber; a flexible membrane (5) separating the sensor from the chamber (6); control and communications electronics (8,9) able to exchange with an external reader in order to transmit a measurement by the said sensor, the sensor (7) being attached to the flexible membrane (5) with which it is in contact.
Claims16
A device for detecting malfunction of a valve/catheters assembly for shunting a cerebrospinal fluid, including:
- a chamber (6,16);
- a laminar channel (4, 14) which opens into said chamber (6,16), on its both sides, and which is adapted to ensure circulation of a shunted fluid, through said chamber (6, 16);
- a pressure measuring sensor (7, 17) for measuring a pressure in said chamber (6, 16);
- a membrane (5, 15) which separates the sensor (7, 17) from the chamber (6, 16);
- a control and communication electronics (8, 9) able to exchange with an external reader in order to transmit an ambulatory measurement by said sensor (7, 17),
- the sensor (7, 17) being added onto the membrane (5, 15) with which it is in contact,
- characterized wherein the walls of the chamber are defined by a rigid housing or a shell, the device being able to be implanted upstream of an intracranial valve of the shunt assembly for direct measurement of the intracranial pressure by the pressure sensor.
