I. How many contact interconnect technologies are commonly used in disposable medical connectors? Many quality connector factories can provide the medical industry with connector products for disposable interconnect applications. There are four common contact interconnect technologies, namely, screw-machined hyperbolic contact technology, stamped hyperbolic contact technology, spring-probe technology, and edge-card contact technology, each of which has unique characteristics designed to meet the specific application, cost, and performance requirements of disposable medical electronics. Hyperbolic Contact Interconnect Technology: Spiral-machined hyperbolic contacts used in reusable connectors provide high performance with low insertion and withdrawal forces, high current ratings, low contact resistance, resistance to shock and vibration, and a high mating life cycle rating when mated with low-cost pull-out male pins in disposable connectors. These contacts help reduce overall device cost while maintaining the high reliability of reusable devices, ensuring thousands of successful mating cycles with simpler disposable connectors. This design also allows the disposable side to be terminated to flexible circuits in large quantities to further reduce the application cost of the device.2. Stamped Hyperbolic Contact Interconnect Technology: Sometimes the reusable components of a medical device, such as extension cables used to connect the reusable device to disposable probes and catheters, are categorized as Restricted-Use Components due to the sterilization process that ultimately leads to degradation. Stamped hyperbolic contacts are ideally suited for these types of restricted-use applications because they offer many of the benefits of screw-machined hyperbolic contacts, including high-reliability wire and insulation, crimp connections, tape-and-reel packaging for compatibility with crimping machines for automated feedthroughs, and interchangeability and intermodality with screw-machined hyperbolic contacts-... But at a lower price, enabling them to be used in equipment that is used multiple times before being discarded and replaced.3. Spring Probe Interconnect Technology: Spring probes are commonly used for test equipment interconnections, but the same attributes that make them ideal for circuit board testers are also well suited for use with disposable medical devices. For example, they can be manufactured in very small diameters, which makes it very feasible to develop extremely high-density connectors with many individual contacts in a reasonably sized plug. Spring probe technology also allows for high compliance length ratios, which enables manufacturers to design connectors with densities of 2 millimeters while maintaining a compliance of 0.5 millimeters. These connectors also tend to be low-profile, which can make them more adaptable to challenging mating conditions and high-vibration environments.4. Edge Card Contact Technology Interconnect Technology: Edge card connectors provide another ideal solution for low-cost, limited-use or disposable medical devices that are customizable, scalable, easy to assemble, and capable of high-density configurations. Since the PCB (usually part of the disposable side of the device) is used as the connector contact, it eliminates the cost of a disposable side contact system, and their plug-and-play design also provides easy termination and virtually eliminates the potential contact damage normally associated with the termination process.
