RFID technology: accurate detection of surgical use of gauze 【Full text】

Dutch NXP Semiconductors announced that the company's RFID chip has been adopted by the United States' ClearCount Medical Solutions' SmartSpongeSystem. The system uses RFID to accurately detect and calculate the gauze used during surgery. The purpose is to prevent gauze from being "forgotten" in the patient's body to ensure patient safety.
Smart gauze
The smart gauze system consists of a gauze "smart gauze" embedded with RFID, a sensor "SmartWand-DTX" that scans the patient's body to detect the RFID in the gauze, and a used gauze recovery device for detecting, reading, and calculating the RFID "smart processing system "composition. Intelligent gauze is provided in a specified number of packages, and the package is read on a RFID reader to read the serial number of each gauze. The number of used gauze is checked against the serial number using an intelligent processing system. In addition, the "final insurance measure" is to use SmartWand-DTX to scan the patient to confirm whether the gauze is left in the patient.

The system is the first RFID-enabled platform approved by the FDA (United States Food and Drug Administration) for use in the operating room. NXP Semiconductors stated: "Surgical gauze can be counted either by hand or with a bar code reader, but blood gauze is difficult to detect in locations that are not visible in the body. With this system, not only can Improve preoperative, intraoperative, and postoperative counting capabilities, which can also significantly improve accuracy and patient safety."

The 2008 “The Journal of the American College of Surgerys” report states that the probability of foreign objects being forgotten is 1 in 5,500 surgical surgeries and 1 in 1000 to 1,500 surgical surgeries. Most people forget about surgical gauze. Because gauze that absorbs blood is hard to read.

The smart gauze system will be presented on the RFID JournalLIVE! 2011 held in Orlando, USA from April 12th to 14th, 2011. The demonstrations and samples will be publicized at the booth of NXP Semiconductors.
