Method of controlling the flow of bodily fluid |
摘要 |
A system and method are disclosed for automatically limiting the drainage of a bodily fluid such as cerebrospinal fluid (CSF) from a patient into a collection chamber. The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber. |
