100 Percent Solids: Superior Adhesive Technology for the Medical Industry

Adhesives using 100 percent solids coating act fast, without need for solvents. In the medical industry, adhesives play a crucial role in applications ranging from diagnostics and device assembly to transdermal and wound care. There are varying methods by which an adhesive can be coated onto a substrate, but solvent coating has dominated in the medical industry for many years. Solvent-coated silicone, acrylic, and rubber-based adhesives are widely used as medical adhesive solutions. Despite their popularity, solvent-coated adhesives are far from a perfect answer to the medical market’s needs. Solvents may contain volatile organic compounds (VOCs) and even carcinogens that can be dangerous to humans. There are also major concerns regarding outgassing or leaching from solvent- coated adhesives in medical settings. As a process, solvent coating is not especially efficient with adhesives requiring drying, which can limit speed and cost-effectiveness of processing.

Integrating Force Sensors into Robotic Surgery

Force sensing resistors provide tactile feedback during robotic surgery. Due to advances in electronics and technology, robotic surgery has become increasingly popular. Surgeons no longer have to operate directly on a patient, but instead can control a robot to carry out the procedure. Robotic surgery has benefits to both the surgeon and the patient. For the surgeon, robots display 3D visualization for enhanced viewing of the operative area and improve the control, precision, and range of motion of smaller instruments. While robotic surgery may seem like the future of the medical industry, it still has obstacles to overcome. One significant disadvantage to robotic surgery is the lack of haptic technology, which provides physical sensations that enable electronics to give their users force feedback.

Addressing Compliance Mandates with Product Lifecycle Management

How lifecycle management software can enhance product development. Regulations from the FDA impact every step of the medical device lifecycle from properly classifying a device and developing a regulatory strategy, to preparing FDA submissions. So, just how are successful medical device manufacturers cost effectively achieving compliance while, at the same time, meeting their product delivery targets?

Improving Single-Patient-Use Model with Disposable Blood Pressure Cuff

Single-use cuff could cut infection spread. Each year, hospital-acquired infections cost hospitals approximately $5 billion in the United States, according to a report in the American Journal of Infection Control. Reducing infection spread helps hospitals avoid these costs and improve patient safety. To help reduce cross-contamination, the Centers for Disease Control and Prevention recommend the use of patient-dedicated products. While catheters, gloves, and the like are high on the hospital’s radar to help address this, blood pressure cuffs are often overlooked, despite research that shows that blood pressure cuffs used on multiple patients can transmit pathogens such as MRSA or C. diff. The single-patient-use cuff solutions that do exist are traditionally expensive, wasteful, and difficult to implement.

Intravenous Fluid Generation System

This system can be used in remote medical facilities where limitations such as lack of refrigeration may limit the type and volume of medical fluids being stored or transported. The ability to stabilize and treat patients on exploration missions will depend on access to needed consumables. Intravenous (IV) fluids have been identified as required consumables. A review of the Space Medicine Exploration Medical Condition List (SMEMCL) lists over 400 medical conditions that could present and require treatment during ISS missions.

The Next Generation of Cold Immersion Dry Suit Design Evolution for Hypothermia Prevention

The system design recovers warm exhaled air and re-circulates it inside the suit. A body at sea is vulnerable to hypothermia, which often leads to loss of life. Hypothermia is caused by the differences between the core body temperature and the surrounding air and seawater temperatures. The greater the differences between the body core temperature and the sea temperature, the more rapidly the core body temperature will drop, and hypothermia can quickly set in. Heat loss is primarily caused by conduction of heat away from the body. Most cold immersion suits on the market are passive designs that only insulate the body against the cold, although some cold immersion suits use special materials such as paraffin to absorb heat and to radiate the heat back to the body. This new utility patent is an active design that relies on the lung’s role as an organic heat exchanger for providing deep body core heating of air. It is based on the fact that the greatest heat loss mechanism for insulated human body immersed in a cold water environment is due to heat loss through respiration.
