Description

From Which Medical Device

The T-Ring digital tourniquet is a simple device which provides reliable haemostasis for surgery on the digits. The device comprises a brightly-coloured outer plastic ring within which is a flexible disc which itself contains a hole. This is supplied in a sterile packet and can be pushed over the lacerated digit to exsanguinate it and provide haemostasis. The ring has two “cutaway” sections on it, which allow its two halves to be separated, pulled apart and gently moved over a larger laceration if appropriate.

Similarly, the device can either be gently slid off the finger or the plastic outer ring can be broken and the inner flexible portion cut. 

The bright colouring and size of the outer ring makes it very unlikely that the device will be left in place after surgery. The UK National Patient Safety Agency has issued guidance about finger tourniquets which states that surgical gloves should not be used as tourniquets, because of incidents of tourniquet retention and loss of the digit.
 
A study has shown that this device provides sufficient pressure to provide haemostasis but at a pressure which is lower than that of a penrose drain or surgical glove tourniquet and which therefore is less likely to cause tissue injury (Lahham et al, 2011).
