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.
我们一直在尝试改进动脉输液泵，现已完成两种新型仪器。一种是常压型，另一种是高压型。常压型泵与普通输液泵相似，但体积更小、重量更轻。尺寸为12.5×12.5×5厘米，装满药物时袋子的重量为250克。因此，它更舒适，能让患者比平时更长时间地持续输液。配备了指示电池电量低的警报机制和输液速度可变功能（2.5 - 20毫升/天）。能源来自市场上容易买到的碱性电池（6 - P型）。装药物袋子的最大容量为50毫升。高压泵的用途是输注高粘度液体（如阿霉素）或需要在短时间内大量输注的药物。导管尖端的最大压力为4千克/平方厘米。如果压力超过此水平，泵将停止并发出警报。尺寸为30×5×5厘米，重量为650克。患者在使用泵输液期间可以轻松移动。这两种新型动脉输液泵有望在未来提供更多的药物选择和自由的治疗组合。
