Injection is the most commonly performed invasive procedure in the hospital. However, the introduction of a needle into a vein in the injection still correlates closely with clinical skills and experiences of clinical workers without relation to advances in medical technology. It is often difficult to find the vein and to insert the needle into the blood vessel, especially if the patient is an infant whose pannicule is thick and blood vessel is thin compared with adults. Multiple failed attempts at needle insertion can incerase patient discomfort with traumas. Therefore, this paper describes the results of preliminary experiments to develop an assistive device tht enables medical staff to achieve an accurate needle puncture into a vein even if the blood vessel is difficult to identify.
