Double gloving with puncture indication for extra safety
The key to maximum safety is making sure that punctures in surgical gloves can be detected as rapidly as possible.

The Biogel® Indicator® System's puncture indications are clear, fast and large 1 – all important factors for immediate puncture detection and a clear path to safety and reduced risk of infection.
- A 2014 Cochrane Review concludes that double gloving reduces the risk of an inner-glove perforation by 71% compared to single gloving 2
- A study by Laine and colleagues conclude that indicator gloves substantially increase the detection for glove perforations during operation. Indicator gloves detect approximately 90% of the perforations, while standard double gloves and single gloves only detect 36% and 23% of the punctures respectively 3.
- Biogel Indicator System detects up to 97% of punctures 4

Protection you can seeThe Biogel Indicator System is unique in that it offers vividly visible puncture detection in three proven way: 1
- Clear– The colour of the inner glove is selected based on colour physics, maximising the sensitivity of the human eye.
- Fast – The gloves are designed to make a puncture visible as fast as possible and to ensure that the regions of indication grow quickly.
- Large – The Biogel puncture indication is large and visible from a distance.
The Biogel PI Micro Indicator system gives significantly clearer indication than other synthetic double-gloving combinations, making punctures visible as fast as possible 5.
How the puncture indication system works
The Biogel Indicator System is made up of a dark-coloured underglove and a straw-coloured overglove.
Normally, the overglove blocks out most of the underglove's colour. When fluid gets between the two layers, light passes through the overglove and reveals the underglove.

The Cochrane reviews: Proof to back it up
When talking to healthcare professionals about prevention strategies, to use a puncture indication system is our most important message. You can see why from these important findings in Cochrane Collaboration's systematic reviews of double gloving 2.
