Recent technical advances have enabled the creation of mobile dialysis device prototypes. These prototypes have been tested for their ability to allow an individual to be dialyzed continuously rather than sporadically. The most recent prototype of a mobile dialysis device aims at increased functionality, which suggests that human factors issues (e.g., efficiency, bulkiness, and weight) are now considered carefully. This study describes advances in the design of an Ambulatory Kidney to Improve Vitality (AKTIV), using an interview protocol during the early stages of product development to capture patients' and caregivers' reactions. The AKTIV has the potential to improve patients' quality of life and decrease mortality rates. The goal of our study is to examine patients' and caregivers' design preferences and feature considerations for an AKTIV. We interviewed 22 participants (age M = 57.50, SD = 13.30), of whom 12 were female and 16 were patients. A pre-interview survey was distributed to the participants, and semi-structured interviews were subsequently held. The pre-interview results show that the belt and backpack designs were preferred over the shoulder bag and distributed designs. The participants also indicated on their pre-interview forms that safety and accuracy were more important to them than attachment ease, comfort, compactness, or operational simplicity. Invisibility and mobility were frequently mentioned when determining the strengths of each of the five design types during the interviews. Finally, individual differences in preferences for the various design types and attributes were identified. The results from our study have important implications for improving efficiency, effectiveness, and user satisfaction in relation to AKTIV prototypes and products. The findings from this interview study will help to ensure engineers and clinicians have target parameters for redesigning the AKTIV.

设计个性化移动透析设备时的人为因素考虑：一项访谈研究。

最近的技术进步使移动透析设备原型的创建成为可能。这些原型已经过测试，可以让个人连续而不是零散地进行透析。移动透析设备的最新原型旨在提高功能性，这表明现在已经仔细考虑了人为因素问题（例如效率，体积和重量）。这项研究描述了在提高产品活力的动态肾脏（AKTIV）设计中的进展，该产品在产品开发的早期阶段就通过访谈协议来捕获患者和护理人员的反应。AKTIV具有改善患者生活质量和降低死亡率的潜力。我们研究的目的是检查患者和护理人员 AKTIV的设计偏好和功能注意事项。我们采访了22位参与者（年龄M = 57.50，SD = 13.30），其中12位为女性，16位为患者。采访前向参与者分发了调查问卷，随后进行了半结构化采访。采访前的结果表明，皮带和背包的设计比肩背包和分布式的设计更受青睐。参与者在面试前的表格中还指出，安全性和准确性对他们而言比安装的舒适性，舒适性，紧凑性或操作简便性更为重要。在采访中确定五种设计类型的优势时，经常提到隐形性和移动性。最后，确定了对各种设计类型和属性的偏好的个体差异。我们的研究结果对于提高AKTIV原型和产品的效率，有效性和用户满意度具有重要意义。这次访谈研究的结果将有助于确保工程师和临床医生具有用于重新设计AKTIV的目标参数。
