摘要:
A blood gas syringe includes a porous plastic plug having a crosslinked hydrogel affixed to a wall of a passageway of the plug. When a blood sample is taken with the syringe, the incoming sample forces air in the system out through the passageway of the plug until the sample contacts the hydrogel, causing the passageway to seal shut.
摘要:
A plastic medical article, such as a catheter or blood collection tube, is coated with a crosslinked hydrogel permanently bound to the inside wall of the tube. The hydrophilic surface provided by the hydrogel prevents adherence of blood components to the surface, and the permanent adherence of the hydrogel prevents its removal by blood.

摘要:
A method for preparing a charged reservoir-electrode unit comprises a first reservoir-electrode disposed to operate as an anode (60) and a second reservoir-electrode disposed to operate as a cathode (62). An iontophoresis reservoir-electrode comprises a backing (12), a bibulous reservoir (18) and a removable closure (24) having an absorbent material.
