Innovative hemodialysis systems are designed to ensure user safety and reduce operational time to allow health-care personnel to focus on patient care. The 6008 CareSystem has been developed to simplify the extracorporeal circuit of the system through a disposable cassette, automate operation steps, and facilitate handling in comparison to its predecessor - the 5008 CorDiax. The present investigations were performed with the aim of evaluating usability, safety, and ergonomic aspects of the new therapy system.
A time-motion study compared these two hemodialysis systems with video and time recording of handling steps required to prepare, operate, and dismantle a dialysis machine. The ergonomic burden on hands and finger joints was evaluated in a second study, again by video-recording the simulated operation of both dialysis systems.
The number of handling steps required for the 6008 CareSystem and critical contact points were reduced by 26% in comparison to the 5008 CorDiax for patients with arteriovenous fistula used for vascular access and by 22% for those with a catheter used for vascular access. Total process time was reduced by 2.83 and 2.57 minutes using fistulae and catheters for vascular access, respectively. The number of hand grips and finger and thumb presses was reduced by approximately 50% and required less strength to execute.
The most recent hemodialysis system confirmed its ease of use and user safety through fewer handling steps and less physical burden on the user. Shorter operational time should enable more patient-focused care.
创新的血液透析系统旨在确保用户安全并减少操作时间，使医护人员能够专注于患者护理。6008 CareSystem的开发旨在通过一次性使用的透析器简化系统的体外循环，实现操作步骤自动化，并相比其前身5008 CorDiax更便于操作。本研究旨在评估这种新型治疗系统的可用性、安全性和人体工程学方面。
进行了一项时间动作研究，通过视频和记录准备、操作和拆卸透析机所需的操作步骤的时间，对这两种血液透析系统进行比较。在第二项研究中，同样通过视频记录两种透析系统的模拟操作，评估了手部和手指关节的人体工程学负担。
对于使用动静脉内瘘作为血管通路的患者，6008 CareSystem所需的操作步骤数量和关键接触点相比5008 CorDiax减少了26%；对于使用导管作为血管通路的患者，减少了22%。使用内瘘和导管作为血管通路时，总操作时间分别减少了2.83分钟和2.57分钟。握力动作以及手指和拇指按压的次数减少了约50%，且执行时所需的力量更小。
最新的血液透析系统通过减少操作步骤和减轻用户的身体负担，证实了其易用性和用户安全性。更短的操作时间应能实现更多以患者为中心的护理。
