High Versatility and Advantages of Flex and Rigid-Flex PCBs
Due to their high versatility, flex and rigid-flex PCBs have been widely integrated into many applications in the medical industry. Since rigid-flex PCBs eliminate the need for connectors, they reduce cost and the amount of installation space required. Their ability to fold into tight spaces makes them useful for medical devices and equipment. As innovations in medical technology continue to reduce the size and weight of devices – especially those that are wearable or portable – rigid-flex PCBs will continue to be sought after throughout the medical industry.
Common Medical Devices Utilizing Flex and Rigid-Flex PCBs
Defibrillators
Defibrillators restore a normal heartbeat by delivering an electrical shock to the heart tissue. There are different types of defibrillators, including implantable defibrillators, wearable defibrillators, automated external defibrillators (AEDs), and manually controlled external defibrillators commonly used in medical facilities. In all types of defibrillators, the PCB controls the electronics that allow these devices to function.
Drug Delivery Systems
The drug delivery system provides controlled release of the drug. There are many types of equipment used for these purposes. One of the most common examples is an infusion pump, which injects drugs such as insulin or analgesics into a patient. In all systems, the PCB ensures accuracy and reliability.
Handheld Devices
Many medical devices are hand-held instruments, cameras, or tools, and operator comfort during use is paramount. Flex and rigid-flex PCBs allow electronic devices to fit into the space available in these devices. Another benefit of rigid-flex technology is its resistance to degradation during autoclaving of medical devices.
Handheld Monitors
Portable medical monitors can reliably monitor vital signs such as blood pressure, pulse oximetry, and body temperature. Flex and rigid-flex PCBs facilitate reliable device functionality and help reduce size and improve portability in recent designs.
Medical Imaging Equipment
Medical imaging equipment is essential for diagnosing and treating a patient’s internal medical problems. Devices such as MRIs, X-rays, pill cameras, and CT scanners all rely on PCBs to operate.
Pacemaker
A pacemaker regulates the rhythm of the heartbeat by sending out electrical pulses. Some need to run continuously, while others only run periodically in a more responsive fashion. In all cases, the PCB is essential for device operation.
