1. Desiphon Anti-siphon Device
Antisiphon is used to prevent the siphon effect, which might occur during hydrocephalus treatment when the CSF requires drainage or shunting and the peritoneal catheter’s position suddenly changes from horizontal to vertical.
Major principle is to create a sudden closure effect in order to overcome the overdrainage that occurs under siphon effect.
Difference in Shunt pressure levels during antisiphon device use
| CATEGORY | STANDARD SHUNT PRESSURE LEVELS (mmH2O) | SHUNT PRESSURE LEVELS WHEN SHUNT IS USED TOGETHER WITH THE ANTISIPHON DEVICE (mmH2O) |
|---|---|---|
| HIGH PRESSURE | 110 - 180 | 135 - 210 |
| MEDIUM PRESSURE | 50 - 110 | 65 - 135 |
| LOW PRESSURE | 10 - 50 | 25 - 65 |
