A pressure ring for a lancing device for holding open a skin puncture while collecting a blood sample includes a col- lar that fits onto the end of a lancing device. A skirt is provided on the collar and a flared portion depends from the skirt. At least one axial slit is formed in the skirt. The pressure ring is made of a flexible material such as polypro- pylene such that when the lancing device with a pressure ring is placed on a person's skin and pressure is applied, the slits spread apart stretching the skin for a puncture by a lance in the lancing device. Once a puncture has been made, the pressure ring holds the puncture wound open to allow bleeding. Removing the lancing device from the puncture site releases the skin allowing the puncture would to close.
