Title:
PAINLESS BLOOD COLLECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2003/094731
Kind Code:
A1
Abstract:
A method of collecting a blood sample in a small amount with no or little pain by puncturing the skin with a needle. Pain at puncturing the skin can be eliminated or relieved by accurately puncturing the skin in a depth of from 0.1 mm to 0.5 mm. This method is usable in many parts of the body including fingers, forearms, abdomen and ear lobules. As novel puncture sites, there have been further developed a back part of a finger from a knuckle joint (the IP joint of a first finger or the DIP joint of one of the second to fifth fingers) to the posterior nail fold and a part from the posterior nail fold to the lateral nail fold. The blood collection method as described above is useful mainly for the blood glucose measurement by a diabetic patient himself/herself. Moreover, it is applicable to other various examinations which can be carried out using a blood sample in a small amount.
