Developing medical devices that are smaller yet offer more functionality is challenge enough. Designers, however, also have to deal with the additional heat that is generated from these devices. This article looks at a number of heat related concerns in today’s medical device designs and outlines a number of available solutions that can be used to address the problem.
How are you influencing implantable devices?
The development of laser technology in the manufacture of medical devices has so exploded in the past 20 years that it is now impossible to fully describe the breadth of applications in anything less than an encyclopedic volume. But a brief recollection of some of the key historical accomplishments and medical devices influenced can help shed light on what we can expect in the next decade.
In the effort to make electronic medical devices smaller, there are a number of obstacles that must be overcome to achieve success. While “just making it smaller” may be the request from the OEM, the component suppliers have a much tougher road to provide the required part. This article looks at a number of factors that need to be examined and offers tips for success.
When seeking power solutions for in-home patient monitoring devices, manufacturers have an array of technologies from which to choose. However, the specific benefits and considerations for each must be evaluated for each application. This article highlights a number of these options and looks to consumer devices as excellent examples of how power technologies can best be used.
How has news questioning the safety of medical devices misled the public about testing protocols?
For electrical and mechanical design engineers in the process of developing applications, choosing a gearmotor can be a tricky and arduous process. Can motors and gearboxes be purchased separately and then matched for an application? Is it better to specify a pre-engineered gearmotor? What are the differences? By following the two gearmotor selection methods readers will receive a checklist of considerations to determine which process would be the most helpful and steps to complete the gearmotor selection process. There are many factors to consider when choosing a gearmotor.
It is estimated that one million burn injuries occur annually in the United States, resulting in 45,000 hospitalizations. The hands are involved with a large number of burn injuries, and partial thickness burns (PTBs) are among the most frequently-occurring types. A PTB is marked by the destruction of the epidermal cell layers of the skin, extending into, but not through, the dermis.
Robust biocompatible material to improves comfort and reduces healthcare costs. Morgan Technical Ceramics (MTC) worked with the UK-based University of Hull to develop a new valve used to restore vocal function for patients with throat cancer. The new tracheo-oesophageal fistula speech valve uses Zyranox™ bio-compatible Yttria partially-stabilized Zirconia, specifically developed for surgical implant devices.
No more painful dental injections. That would be music to the ears of millions of people in the U.S. and around the world who fear going to the dentist. According to studies from the Dental Fears Research Clinic at the University of Washington Dental School in Seattle, upwards of 50 million Americans avoid the dentist due to their fear of pain. Most often, it’s the pain associated with dreaded dental injections. The fact is that dentistry itself doesn’t hurt – injections do.
A look inside the design of cancer detection and imaging technology offers insight on the time, footprint and specification challenges inherent to medical product development.
Micro-machining technology, simply stated, is the utilization of semiconductor manufacturing equipment in such a way that it creates micro-mechanical systems that serve a specific purpose. MEDER’s objective was to develop a micro-miniature hermetically sealed reed switch that is able to function exactly like the larger, standard hermetically sealed reed switch.
Advances in adhesives, materials, software and sensor technologies are spurring development of a new generation of wearable sensors and monitors for medical and health management applications. A notable example is a patch-based wearable sensor that adheres comfortably to the user’s skin and continuously gathers physiological and lifestyle information, with certain versions that will include vital signs and other indicators for up to seven days. The patch-based wearable sensor represents a major advancement in personal monitoring device design, functionality and wear time.
The patient lies wide awake in the operating room (OR), the top of his draped head bared to the neurosurgeon. A second doctor stands at the patient’s side, lifts the man’s arm, and flexes it gently. The hand and wrist are stiff, with a visible tremor. The surgeon makes a slight adjustment to brain-penetrating electrodes mounted through a starburst-shaped plastic fixture fastened to the man’s skull. “How about now?” the surgeon asks. The arm is moved again, this time naturally, smoothly, without shaking. “That’s it,” says the patient, nodding his head with relief.
Many manufacturers face challenges with energy costs, employee comfort and product integrity year-round. Large diameter, low speed fans go to work to overcome these challenges in industrial facilities around the world. As a means of effective air circulation, big fans reduce condensation, improve overall air quality, disperse localized fumes and keep workers comfortable with smooth, non-turbulent airflow.
