Zimmer Air Cooling Equipment

Unlike other cooling methods (contact cooling, cryogen spray, ice packs, etc.) Zimmer can cool the epidermis before, during and after laser energy has been applied, that too without interfering with the laser beam. The zimmer cooling machine minimises pain and thermal injury during laser and dermatological treatments and for temporary topical anaesthetic relief for injections. It delivers chilled air throughout the procedure and ensures a high level of patient comfort. By convection cooling, the skin surface temperature decreases to approximately 15°C in 8 s. Indications are port-wine stains and other vascular lesions, hair removal and tattoos.The advantages of the Zimmer cooling machine are its compatibility with every laser device, unrestricted view of the lesion, and high comfort level for both the patient and the physician. Some practitioners also use a skin cooler machine as an alternative cooling method, though it may not offer the same level of integration with laser procedures.Demerits include a feeling of suffocation and a risk of frostbite in case of exaggerated cooling. The latest generation of non-contact cooling devices utilises convection method of cooling by delivering a continuous flow of chilled air at −30°C at adjustable flow rates, that too without interfering with the laser beam. in 2000 and found to be safe and inexpensive. In fact, this method is also not free of any adverse effects. Increased incidence of post-inflammatory hyperpigmentation has been demonstrated with continuous cold air cooling.
