Testing equipment continues to advance

“The whole push from our side is on productivity,” Evans said. “Making it really easy for the end user is our priority.”

Datrend Systems has also added features to its vPad-Mini, a small safety tester released at the beginning of 2018.

Quest Imaging Solutions provides all major brands of surgical c-arms (new and refurbished) and carries a large inventory for purchase or rent. With over 20 years in the medical equipment business we can help you fulfill your equipment needs

New firmware allows the device to record test results and send them to devices, including printers, via a Bluetooth connection. On the original unit, a biomedical engineer would manually record the results.

Multiple test results can now also be saved into the VPad-Mini’s memory.

Fluke Biomedical
Last January, Fluke Biomedical released two gas flow analyzers, the VT650 and VT900A. Both models measure flow, pressure and volume, along with oxygen concentration used on equipment such as ventilators and anesthesia machines.

Both models come with a 7-inch color touchscreen display and a single flow channel that automatically compensates for temperature, humidity and pressure. Both models have the ability to save test profiles specific to the brand and model of gas flow devices.

“You just save your test profile and you’re ready to go,” said Michael Raiche, a product manager at Fluke Biomedical.

The VT 900A has an added external TTL trigger and ultra-low flow, and ultra-low-pressure ports that allow it to test devices that require more accurate measurements at low flows and pressures, such as pediatric ventilators and anesthesia machines.

The models weigh less than the predecessor equipment.

“We’ve moved from a bench-top model to one that’s more portable,” Raiche said. “It’s no longer something you have to keep in the shop, it’s something you can bring with you.”

They come with eight hours of battery life and onboard memory, and biomedical engineers can pull off the test results using an Excel plugin.

The company is also releasing a new anesthesia testing accessory called VAPOR that measures anesthetic agent concentration as well CO2 and N2O concentration.

“Now you can do preventive maintenance on the vaporizer portion of an anesthesia machine,” Raiche said.

VAPOR detects how much of an agent is being administered to the patient through the anesthesia delivery system, Raiche said. It can detect two gases at the same time, which identifies failure modes that other models might miss.

“Other products on the market can only detect one gas at a time,” Raiche said. “When a vaporizer is operating properly, you should only see the agent you’ve turned on. If you’re seeing two agents at the same time, that should be a red flag.”

Gammex, a Sun Nuclear Company, recently made a number of improvements to its electron density phantom, which is used in radiotherapy to determine the relationship between tissue density and scanner values, as needed to determine the amount of radiation needed to treat a tumor.
