摘要： A medical fluid infusion system including: a fluid pathway for transporting a pulsatile flow of fluid; a dampening element in communication with the fluid pathway, the dampening element configured to actively dampen pressure fluctuations of the pulsatile flow to smoothen the pulsatile fluid flow, the dampening element operable in any orientation; and a fluid flow sensor disposed along the fluid pathway downstream of the dampening element to measure the flow rate of the smoothened fluid flow.

摘要： A real-time, non-invasive system and method for determining the level of an analyte of interest in the urine of a patient is disclosed. The system and method uses the measured level of an analyte of interest to detect the onset of acute renal failure (ARF) as early as possible to prevent that patient from developing the disease or mitigating the effects of the disease. The system and method may be used to monitor the recovery of a patient after an ARF diagnosis. Preferably, the analyte of interest is creatinine or urea. The system may be placed in the urine drain line of a patient between a Foley catheter or other urinary drain and a urine collection bag. The system makes substantially continuous measurements of the urine flow rate and the concentration of the analyte of interest to determine the mass excretion rate of the analyte so it may be monitored to detect if the patient experiences a delta change in the mass excretion rate of an analyte that is indicative of the onset of ARF or a change in renal function.

摘要： Method of and apparatus for dosing powders by weight. To introduce a weight of powder with a predetermined final value P.sub.3 into a weighing receptacle, the functioning of mechanism for positively feeding the powder to the receptacle is controlled by a continuous comparison between the effective weight of powder received by the receptacle following an initial instant t.sub.0 and a theoretical weight conforming to an ideal evolution of such weight of powder as a function of time; at a final predetermined instant t.sub.2 with reference to the initial instant t.sub.0, the positive feeding mechanism is stopped and the powder remaining is allowed to run into the weighing receptacle in an amount corresponding to the amount of poweder which is lost during its transmission by the feeding mechanism.
