Healthmark Industries has announced the addition of the single-use vest to its Cool Aids product line. Cool Aids Single-Use Vests are designed to manage the core body temperature. Worn under protective barrier attire, they are ideal for use by staff during surgery, reprocessing of devices and other activities because cooling is achieved with reusable cooling packs rather than with a system of hoses and an external source. This innovative design allows for greater freedom of movement without worrying how to get them laundered and returned. Visit www.hmark.com or call 800-521-6224 for more information.
