Abstract: A smokeless, low noise electrosurgical device includes a tubular housing having a passage extending axially therethrough, with one end of the passage connected to a source of negative gauge pressure. The other, inlet end of the housing is provided with an electrosurgical cutting device or cauterizing probe extending therefrom. The inlet to the passage comprises a wide opening having side walls which converge to a relatively narrow port in flow communication with the passage in the housing. The port is significantly narrower than the passage, resulting in significantly reduced noise generated by the fluid flow into the inlet and through the passage.

Abstract: A bracelet adapted to secure an intravenous tube to the wrist of a medical patient is formed of a single elongated strip of flexible plastic material. One end of the strip tapers to a rounded point, with a plurality of ratchet teeth formed in the edges of the strip adjacent to the tapered portion. The opposite end is provided with an opening to receive the first end and to engage the ratchet teeth and form a loop of adjustable length, with a pair of lateral slots provided to retain the distal portion of the first end flush with the bracelet. The medial portion of the strip includes a plurality of pairs of longitudinally extending slots, each pair adapted to receive the intravenous tube therethrough, so that the tube may be secured by describing a retrocurved configuration through the bracelet slots.
