Poor contact between timesco stubby handles and timesco laryngoscope blades, which may result in the bulb not being lit with subsequent delays to intubation. timesco believe that there may be a possibility that the electrical contact on the stubby handle may become bent out of position when used with an early design of callisto disposable blade (pre november 2003), which depressed the bulb slightly more than the current timesco callisto single-use design and other timesco reuseable blades. this could have resulted in the bulb failing to be lit if the handle was subsequently used with any current timesco design blade. the stubby handle electrical contact is shown in figure 1 below. timesco sent a letter to inform customers of this issue in february 2007 and, as a precautionary measure, they implemented a redesigned contact mechanism in the stubby handle in january 2007 figure 1. stubby handle electrical contact.

Identify all stubby handles that are currently in use. Regularly check that the contact spring is adequately elevated to make good contact with the laryngoscope bulb when the bulb is depressed. Check the function of the handles before each use.
