Abstract: An arm band for stabilizing an intravenous needle inserted into a patient's vein. The arm band is provided with a hole in the body thereof, spaced from a side edge of the band. The hole is dimensioned to surround the needle. The band is further formed with a slit from a side edge thereof to the hole, to provide opposing flaps which open to permit passage over the tube part of the inserted intravenous needle. A strip is secured at one end thereof to the band on one side of the slit. The free end of the strip is extended over the slit, causing the edge of the hole to surround the needle. The free end of the strip is provided with means to secure it to the band on the other side of the slit, thereby obtaining the stabilization of the intravenous needle.
