In order to improve the maintenance of medical equipment and reduce the loss of the situation, Worren Medical Systems is gradually placing active RFID tags on wheelchairs, oxygen cylinders and other medical equipment to be rented to customers.
On July 25, 2006, Worren Medical Systems, a pharmaceutical wholesaler in the Midwestern United States, attached RFID tags to many medical devices leased to or sold to customers. By applying RFID tags, both the company and customers can better Track the inventory of products and ensure regular maintenance of the products.
The company applies 915MHz active tags to syringes, portable MRI machines, wheelchairs, oxygen cylinders, automatic defibrillators, and other medical devices. Each label has a UID identification code, which is used in conjunction with the electronic tracking software WrenTrack provided by Wren Medical Systems. renTrack records the life cycle of each product, so that the suppliers and users of home care products can track these products Where they are sent to, the cleaning and maintenance of these products can also be monitored. Now, the application of RFID tags adds extra protection to the barcode system, ensuring that medical instruments can be produced, cleaned, maintained and stored in accordance with regulations.
At present, users of Worren Company use handheld infrared readers to scan barcode labels on medical devices stored in checkpoints. For example, when a worker starts to check an automatic defibrillator that is about to be sent to the patient’s home, he uses a reader to scan the barcode on the automatic defibrillator, and the barcode information scanned by the reader is fed back to the surrounding computers , Display the answers to a series of questions through WrenTrack software. These questions include the name of the worker, why the medical device will be inspected, and where will the medical device be shipped. If the equipment is about to undergo the expected maintenance inspection, the employees will also know the first time. With the addition of RFID tags, the supervision work becomes very simple: if an employee forgets to scan the barcode on the medical equipment, or the information in the software has been filled, when the instrument is moved, an RFID read and write installed at the checkpoint The device will read the RFID tag on the medical device, alert the WrenTrack system, and display it on all computers running this software.
Woren Medical Systems has the ownership of all medical devices leased to users. So the company hopes to supervise the storage and maintenance of those medical devices. WrenTrack software is a web-based software that allows Wren Medical Systems to easily track all medical devices from the headquarters.
So far, Worren Medical Systems has used barcodes on approximately 50,000 different medical equipment materials, and plans to equip more than 100,000 medical equipment materials with barcodes in the next 8 months. Company Chairman Michael Ward said that by that time Worren Medical Systems will use RFID tags on approximately 25,000 medical device materials.
The WrenTrack software system requires at least one RFID reader, which can read tags within a radius of 100 meters. Ward said: For most users, a reader can provide enough reading range. Each reader is connected to a network server with an IP address, so Woren Medical Systems can track the location of the RFID reader through the user’s location. Ward provides users with comprehensive installation and commissioning. WrenTrack system, barcode scanner and RFID hardware can all be provided by Wren medical, users only need to pay. Woren Medical System Co., Ltd. is responsible for debugging the software, installing the equipment, and assembling according to user requirements. So far, Wren Medical Systems has operated the WrenTrack system in approximately 200 locations.
Warren Medical Systems believes that the use of RFID technology can improve asset management for the company and for users. Ward said, “Since RFID, if any unscanned medical equipment leaves a certain site, we will know for the first time. Ward explained: By using barcodes and RFID tags at the same time, we know what real inventory management is.
With the use of RFID tags, the amount of inventory is more accurate, and customer expenses are also reduced. The medical equipment that users rent or buy costs an average of US$2,000 per year. The user’s loss amounts to 10-15% of these costs. In addition, because nursing companies cannot retrieve medical devices from patients in time, they have to rent or purchase 30 to 35 percent more equipment than they actually need.
Ward said, “RFID technology can make inventory management more rigorous, save the number of medical equipment needed, and reduce the number of lost medical equipment.
