Abstract
A tracheostomy tube flange (13) of a liquid silicone material has openings (14) towards opposite ends for receiving ends of a neck strap. The openings (14) are reinforced with overmoulded inserts (137, 138) of a heat cured silicone material having a similar hardness to that of the flange material. The inserts (137, 138) have an outwardly-projecting ledge (144) between their ends.
Claims11
A tracheostomy tube including a shaft and a mounting flange towards a machine end of the shaft, the mounting flange extending radially outwardly of the tube and being provided with an opening towards each end, the opening configured to receive a securing means to retain the tube with a patient's neck, characterised in that the flange is of a first silicone material overmoulded on two reinforcement inserts at respective ones of the openings, and that the reinforcement inserts are of a heat-cured silicone rubber material different from the first silicone material.
A method of manufacture of a mounting flange of a tracheostomy tube including the steps of moulding two inserts of a heat-cured silicone rubber material, both inserts having a passage therethrough and an outer projection, and overmoulding the two inserts about their outer projection with a silicone material different from that of the inserts to form a mounting flange of the tube where the passage through each insert provides an opening towards opposite ends of the flange, the opening configured to receive a securing means.
A tube having a mounting flange manufactured by moulding two inserts of a heat-cured silicone rubber material, both inserts having a passage therethrough and an outer projection, and overmoulding the two inserts about their outer projection with a silicone material different from that of the inserts to form a mounting flange of the tube where the passage through each insert provides an opening towards opposite ends of the flange, the opening configured to receive a securing means.
