<p>A medical syringe driver (6) provides a slow steady rate infusion of fluid which is broken into an intermittent bolus infusion by provision of a compressible chamber (4) in the fluid pathway which is allowed to fill with fluid, being compressed intermittently under electronic control by an external piston (3). A timing pulse from a ventilator device or other appropriate source (16) is modified by a control circuit (15) so as to allow the instillation of fluid to be precisely related to the cycle of the timing device, both in time and frequency, in order to control the infusion of the fluid into the patient's respiratory system. Alternatively, a valve system allows the compression system to pump the fluid as well as dividing the flow. <IMAGE></p> |
