  • Medical tube position confirmation device
    Patent number: 10646407
    Abstract: A feeding tube position confirmation device 102, operable to confirm the position of a predetermined portion of a medical feeding tube in a predetermined portion of a human or animal body, the position confirmation device comprising an optical waveguide 106 dimensioned to be insertable into the lumen of the feeding tube, the optical waveguide having a sensing distal end 108 comprising a distal end material and a sensing material mixed with the distal end material, the sensing material operable to provide a change in optical properties at the distal end 110 of the optical waveguide dependent on the environment to which the sensing distal end 108 of the waveguide is exposed. The sensing material may comprise a reflective material. Methods of manufacture and use of such devices are also described.
    Type: Grant
