Medical Devices Manufacturing in the US
根据《食品,药物和化妆品法》,美国食品和药物管理局基于确保安全性和有效性所需的控制水平认可三类的医疗设备。The classification procedures are described in the Code of Federal Regulations, Title 21, part 860 (usually known as 21 CFR 860). The USFDA allows Medical device marketing in two different processes.最常见510(k)过程and second is Premarket Approval process, i在批准前批准的情况下,需要进行临床试验More details as below
Class I
Class I devices are subject to the least regulatory controlled. Most Class I devices are exempt from the premarket notification and a few are also exempted from most good manufacturing practices regulation. Examples of Class I devices include elastic bandages, examination gloves, and hand-held surgical instruments.
Class II
一般单独控制不能保证安全的d effectiveness of Class II Medical Devices, Devices in Class II are held to a higher level of assurance than Class I devices. Examples of Class II devices include acupuncture needles, powered wheelchairs, infusion pumps, air purifiers, and surgical drapes.
Class III
A Class III device is one for which insufficient information exists to assure safety and effectiveness solely through the general or special controls sufficient for Class I or Class II devices.III类设备通常是支持或维持人类生命的设备,对于防止人类健康损害或带来潜在的,不合理的疾病或伤害风险。当前需要前市场通知的III类设备的示例包括可植入的起搏器,脉冲发生器,HIV诊断测试,自动化外部除颤器和内对植入物。医疗设备制造需要根据设备的分类来控制过程。较高的风险;更多控件。在初始研发阶段时,制造商现在开始设计用于制造性。这意味着产品可以更精确地工程生产,从而导致交货时间较短,公差和更高级的规格和原型。如今,借助CAD或建模平台,这项工作现在更快了,这也可以作为战略设计生成和营销工具的工具。
