PCT No. PCT/NO88/00013 Sec. 371 Date Oct. 24, 1988 Sec. 102(e) Date Oct. 24, 1988 PCT Filed Feb. 17, 1988 PCT Pub. No. WO88/06427 PCT Pub. Date Sep. 7, 1988.An adhesive-backed strip is stuck onto a patient's skin. The strip has an opening provided through it at the site where a blood sample is to be taken. On its outer side, the strip is provided with an upstanding annular collar surrounding the opening through the strip, thereby providing a sump bottomed by the surface of the subject's skin. The sump receives a plug of liquid-absorptive material. As the subject's skin is pierced by a cannula, inserted down through the sump, to take a blood sample, the initial exudate, including capillary blood and other tissue fluids, exudes into the sump where it is absorbed by the plug. Thereafter, venous blood is conventionally drawn into the cannula while the bandage remains in place. |
