A surgical safety device to be fixed externally to the body of a patient fitted with a body tube for securing the body tube against unintentional displacement into or out of the patient, comprises a bore (3,5) for receiving the tube, an element (6) for gripping the tube, and means (1,2) for selectively adjusting the element (6) between a tube gripping position and a tube released position. As shown, two tubular members (1,2) are partially telescoped together and the gripping element (6) has its opposite ends (7,8) fast with the respective members for strips (11) of the element to be wound spirally around the tube in response to relative rotation of the tubular members (1,2). A ratchet system (12,13) serves to lock the members (1,2) in the tube gripping position. A method of securing a surgical body tube is characterised by the steps of passing the body tube through the bore (3,5) of the safety device, adjusting the safety device to grip securely the body tube without collapsing it, and fixing the safety device to the external body surface of the patient. |
