[New type pump for continuous arterial infusion].
Abstract
We have been attempting to improve the arterial infusion pump, and two new type instruments have been completed. One is the normopressure type and another is the high pressure type. The normopressure type pump is similar to the usual infusion pump but it is much more compact and light. The size is 12.5 x 12.5 x 5 cm, and the weight is 250 grams when the bag is full of drug. Therefore, it is more comfortable and enables patients to continue the infusion longer than usual. An alarm mechanism to indicate a low power of battery and a changeable function for infusing speed (2.5-20 ml/day) are equipped. The energy source is obtained from an alkaline battery (6-P type) which is easily bought on the market. The maximum volume of the bag for drug is 50 ml. The purpose of the high-pressure pump is the infusion of fluids of higher viscosity (e.g., adriamycin) or a drug requiring a large volume over a short time. The maximum pressure at the tip of the catheter is 4 kg/cm2. If the pressure is beyond this level, the pump stops and the alarm sounds. The size is 30 x 5 x 5 cm and weight is 650 grams. The patient can easily move during infusion with the pump. These two new pumps for arterial infusion promise a greater choice of drugs and free combination of therapy in the future.
