Positive control intravenous fluid administration |
摘要 |
A method and apparatus for parenteral administration of medical fluids has a normally closed clamp on the intraveneous feeding tube which is opened by means of an electromagnetic actuator at a preselected drop frequency rate and closed when a drop is detected by a conductive path established by the drop passing between two opposing electrodes. The electrical system governing the drop counting electrodes also is provided with drop size measuring means which acts to control the preselected drop frequency rate wherein a desired volumetric rate is maintained. Safety features are also provided to prevent excessive or insufficient flow rates.
