Continuous Positive Airway Pressure (CPAP) machines are used to treat sleep apnea, a disorder that restricts breathing, and potentially causes stress to both the heart and circulatory system. Sensortechnics’ HDI and HCE series pressure sensors monitor the instantaneous pressure at the output of the machine and inside the breathing mask, increasing accuracy and sensitivity for individual CPAP users.
Despite innovations concerning resins in medical devices, extrusion processing challenges still occur. If one has trouble maintaining the high precision required for smaller diameters, thinner walls, and tighter tolerances common to medical tubing and other products, four pieces of advice should be followed.
Metal injection molding (MIM) is a metal processing method that has become a beneficial manufacturing technology for the medical device industry, as it can produce complex-shaped, high-density, and high-performance metal parts at a low cost. Designers and engineers in the medical devices field are able to compare MIM to traditional machining techniques in the small parts arena.
A new method in examining test subject behavior has been developed by the Tufts Center for Regenerative and Developmental Biology partnering with Wireless Techniques. Given that manual methods performed by human researchers can be inaccurate, expensive, and time-consuming, the new automated learning and testing chamber can instead analyze the behavior of small animals on a 24/7 basis, with several experiments running at the same time. As a result, greater insight will be achieved in the area of learning and memory.
For engineers and designers of medical devices, familiarity with U.S. patent rights is necessary to protect inventions. Before filing an application, it is important to distinguish "prior-art" from "novel" inventions.
Designing portable medical devices offers a multitude of challenges, from space constraints to interference issues to ergonomic concerns. Arguably, however, none of these are more serious than optimizing power use within the system. This Tech Brief reviews a number of methods designers can consider when developing their next portable medical device.
Why do medical device companies choose to pursue vertical integration? How does vertical integration cause technology drift over time? How can outsourcing be used strategically in key circumstances to gain valuable access to otherwise unavailable and diverse solutions from non-medical industries? This article addresses all of these questions for medical device manufacturers.
The Project: Determine the best DC motor with which to drive a power wheelchair or mobility scooter. The Solution: Using the innovative web tools and design expertise of one supplier of DC motors, manufacturers can be assured of making the best choice.
Implantables are already well established as a medical device solution, but this sector is achieving explosive growth with the development of new technologies. This article provides an overview of microelectronics packaging technology evolution, following how designs have been made to accommodate ever increasing demands for lightweight and smaller size modules.
Besides "early collaboration," what tip do you have for medical device designers developing a new project that is specific to your area of the industry?

As medical device trends continue toward smaller devices, manufacturers are looking to miniature components for greater capabilities. As such, miniature pumps are being sought that deliver more enhanced performance. However, ensuring the right motor technology is driving the pump to achieve the desired result can be just as great a challenge.
The Project: Find a material that will offer durability and protection for a portable therapeutic hypothermia system used by emergency personnel. The Solution: A PC/ABS plastic was used for a number of components in the device since it offered impact strength, flame and chemical resistance, and light weight.
