Abstract

A breakthrough in peritoneal dialysis (PD) therapy occurred in 1977 with the development of continuous ambulatory peritoneal dialysis (CAPD). Its simplicity, low cost, and ease with which CAPD could be performed on patients at home contributed to the popularity of this procedure. However, there is a need for continuous improvement in building optimal systems for incident chronic kidney disease (CKD) patients. This research showed the design and construction of a simplified prototype of low-cost automated peritoneal dialysis (APD) equipment that meets international standards to automatically regulate infusion and fluid drainage in and out of a patient with low margins of error. Experimental tests allowed the adjustment of the RPM values concerning the flow rate provided. In addition, thanks to the pressure sensor, it was possible to observe a fluctuation ranging from 9 to 13 kPa, which is within the permissible average specified in the catalogs of medical instruments and equipment. Furthermore, a turbidity sensor was added to decrease the possibility of presenting peritonitis. The results showed absolute values of flow, angular velocity, and pressure that it could deliver for use in APD therapies. Finally, the construction of the APD equipment is presented generally, showing the electronic and mechanical components that constitute it.

摘要

1977年，随着持续性非卧床腹膜透析（CAPD）的发展，腹膜透析（PD）治疗取得了突破。CAPD的简单性、低成本以及能够在患者家中轻松进行的特点，促使该方法广受欢迎。然而，为初发慢性肾脏病（CKD）患者构建优化系统仍需不断改进。本研究展示了一种符合国际标准的低成本自动腹膜透析（APD）设备简化原型的设计与构建，该设备能以低误差自动调节患者体内的液体输注和排出。实验测试允许对所提供流速的转速值进行调整。此外，借助压力传感器，可以观察到9至13千帕的波动范围，这在医疗器械和设备目录规定的允许平均值范围内。此外，增加了一个浊度传感器以降低发生腹膜炎的可能性。结果显示了其在APD治疗中可提供的流量、角速度和压力的绝对值。最后，总体介绍了APD设备的构造，展示了构成该设备的电子和机械部件。
