SurgiVet NIBP Purple Cuffs. SurgiVet® NIBP Cuffs fit patients comfortably because of a 360 degree bladder that eliminates the need to align an arrow/mark over an artery. The durable cuffs will withstand 10,000 inflations and are machine washable. SurgiVet’s purple cuffs act more like a transducer than a cuff giving you a faster reading with less hassle. Each cuff can be used on animals of various sizes eliminating the need for a large range of cuff sizes. Sizes: Small Cuff 3-9cm (B1), Medium Cuff 5-15cm (B2), Large Cuff 9-25cm (B3) or Extra Large Cuff 17-45cm (B4). Available individually or in a set which includes an air hose.
