System for Tracking Sharps and Tools in the Operating Room

posted on 07/01/2009
Instrument tracking and inventory control are burgeoning areas in hospital device development as safety initiatives and economic pressure for improved efficiency prompt hospitals and their insurers to develop improved means to satisfy rapidly evolving criteria. By combining expertise and observation in the operating room (OR) with chemistry and nano-engineering advances outside the OR, UC inventors have developed a proprietary, automated system that can scan and control a wide variety of materials that are routinely used in the surgical theater.
Suggested Uses
A proprietary system comprised of a device, novel coding materials, and software enables efficient scanning, tracking, and inventory of diverse surgical tools, including both disposable (sharps and sponges) and re-usable instruments found in an operating room. One of many configurations would use unique tags to identify each type of object (e.g., scalpels, needles, sponges, and scissors).
Advantages
A prototype can be directly translated to a commercial product with the following advantages:
- Easily adapted into any hospital setting, worldwide.
- Safety and regulatory concerns will sustain this as a high-growth area.
- Device uses optical technology that is readily available.
- Simplified workflow can increase efficiency for OR staff and reduce the frequency of errors and injury.
Detailed Description
The identification system relies on reading and classifying the pattern and fluorescence spectrum of nano-quantum dot-based “tags” which are detected as each surgical material is transferred to a receptacle, such as a container or a tray. This approach immediately provides three distinct competitive advantages over alternative solutions, such as radio frequency identification (RFID) and bar code systems. First, RFID/bar code systems are not compatible with the environment of the OR, which requires fast and sensitive detection in the milieu of body fluids. Secondly, the combination of printed optical patterns and fluorescence spectra facilitates the identification of millions of different items. Finally, alternative approaches lack the dual ability to (i) prepare surgical tray instruments and (ii) scan and track instruments as they are used.
