Figure 6. Silicone Tracheostomy Tube
Figure 6 is a representative example of silicone-based medical products involving tubes
or catheters. A tracheostomy tube, or "trach tube," is a 2- to 3-inch-long curved metal
or plastic tube placed in a surgically created opening (tracheostomy) in the windpipe to
keep it open. Versions of these products are used in cases where patients have
difficulty breathing on their own, such as in a spinal cord injury.
A product known as Mepiform™ is an example of silicone use in a sheet form for the
management of scars, particularly keloid scars. Figure 7 shows this product.
