Reviews and News on Medical Equipment

Long the domain of engineers and manufacturing professionals, flow meters have traditional been used to measure the volumetric flow rate of gases and liquids. They are typically found within machinery that falls outside of the medical profession, but a few companies have found ways to use these devices in circulatory support systems, particularly while patients recover from heart surgery.

The industrial community uses flow meters for a number of different applications, including power plants, water treatment facilities, and chemical centers. They are typically a measurement device for water, corrosives, coolants, compressed air, hydrogen, carbon dioxide and many other fluids and gases. When treating acute heart failure, medical professionals are now able to use flow meters to function as a way to detect the flow of blood through the heart while a patient recovers.

Universal Flow Monitors creates custom-designed flow stream devices for use in the machines made by many well-known medical equipment manufacturers. These unique flow meters are used to drive air pulses to the ventricular assist devices used in cardiac recovery units. By controlling the pumping action of the machine, flow meters analyze the state of the pump to ensure that it is using the correct timing and pressure while it empties and fills corresponding ventricular pumps.

By working closely with medical equipment manufacturers who specialize in ventricular assist devices (VADs), these very unique flow meters are designed to measure relationships between pressure drop and flow within the human heart. The meters also use a temperature sensor and an absolute pressure sensor to compensate for variances in density. Additionally, these flow meters use a bidirectional feature to measure air flow both to and from the blood pumps.

As a supplier to the medical equipment industry, Universal Flow Meters has worked with manufacturers to successfully align their products with the stringent demands of heart recovery systems.

Surgeons are constantly being presented with new technologies that enhance their ability to treat patients, but one of the most important elements of a surgical unit is often overlooked. Maintaining a well-lit surgical suite throughout procedures is a crucial to both the medical team and the patient. Until recently, the Xenon bulb has been used by most health care facilities, but this type of lighting brings a number of legitimate concerns.

Medical equipment designers are moving away from less efficient sources of light and using LEDs for an increasing number of medical applications. The implementation of LED technology in surgical settings eliminates the disadvantages of Xenon lighting. This is because Xenon bulbs reach temperatures up to 260°C, generate a distracting noise, and consume up to 400 watts of power, which can present electrical hazards such as overheating. In addition, Xenon bulbs are powered with bulky fiber optic cables that can restrict movement around the operating table. Any entanglement of the cable during surgery could cause it to unplug, resulting in light failure in a critical procedure.

Here are some of the advantages of using LED lighting in medical equipment:

* LED lighting uses a lighter-weight headlamp, which is more comfortable for surgeons
* The units are engineered with a rechargeable battery that allows them to operate continuously during surgery
* LED surgical lighting replicates the white lighting found naturally in sunlight, which is optimal during surgical procedures
* LED bulbs last between 8,000 and 50,000 hours, which is a vast improvement over Xenon’s life expectancy of 600 to 1,000 hours
* LED uses less power, making it a more energy efficient alternative

Overall, LED lighting is proven to be a more effective and energy-efficient source of light during surgery. Due to high customer demand, medical equipment manufacturers are expected to implement new LED lighting within surgical equipment.
