A new system for ultrafiltration control during hemodialysis is described. The apparatus consists of a computer operated system of load cells that register variations in weight of the outlet dialysate versus inlet dialysate. Once the weight loss of the patient has been established, the gravimetric control operates on the dialysate circuit to obtain the transmembrane pressure adequate to achieve the desired ultrafiltration rate and patient weight loss. The system can be used as a complete dialysis machine or as a separate module that can be adapted to any standard dialysis machine. This module was tested in more than 220 dialysis sessions, using different membranes and ultrafiltration rates. The difference between the scheduled and the real weight loss was always less than 100 g at the end of the dialysis session. The number of technical interventions required were few, as was the rate of complications related to the system. The system is safe and reliable and offers a low cost opportunity to improve dialysis tolerance by accurate and progressive ultrafiltration during the session.
本文描述了一种用于血液透析期间超滤控制的新系统。该装置由一个计算机操作的称重传感器系统组成，该系统记录流出透析液与流入透析液重量的变化。一旦确定了患者的体重减轻情况，重量控制就会作用于透析液回路，以获得足以实现所需超滤率和患者体重减轻的跨膜压力。该系统既可以用作完整的透析机，也可以用作可适配任何标准透析机的单独模块。该模块在220多次透析过程中进行了测试，使用了不同的膜和超滤率。在透析结束时，计划体重减轻与实际体重减轻之间的差异始终小于100克。所需的技术干预次数很少，与该系统相关的并发症发生率也很低。该系统安全可靠，并且通过在透析过程中进行精确和逐步的超滤，提供了一个低成本的机会来提高透析耐受性。
