The McKesson Two-Layer Compression Bandage System from McKesson, available through LabSupplies.com.Features & Benefits Multilayer compression system to be used on intact skin Wounds must be treated with a suitable wound dressing in advance. Bandage system simultaneously absorbs, protects and provides sustained therapeutic compression for up to 7 days when applied as directed. Visual diamond indicator on cohesive bandage helps with correct application. Diamond indicator forms a square signaling sufficient stretch to achieve the required compression pressure. Short stretch properties yield high working pressure and low resting pressure (in mobile patients); helps reduce edema. Breathable Both layers are tearable by hand. Standard compression rating 30 – 40 mmHg Both bandages must be used together to provide a secure, thin, nonslip compression dressing.
