<b>Necessity of Precautions Against Expired and Broken Press Tack Needle</b> / 日本東洋医学雑誌

ABSTRACT

In Japan, controlled devices for medical professionals have been often purchased by people other than acupuncturists or doctors, using the Internet sales system. Press Tack Needle (PYONEX^®) allows easy handling by combining a plastic part with an adhesive tape. Since it has been reported to be relatively safe with limited adverse events such as adhesive-related dermatitis or similarly mild disorders, it is widely used. We report a case that when the patient removed a PYONEX^® which applied by himself, the needle tip was broken and remained in his body. It might lead to an accident such as injury due to a broken needle left in the body. The patient had purchased the PYONEX^® on his own judgments, storing it for a long period of time, applied it to his body 10 months after its expiration date and kept it attached for approximately 3 weeks. Plastics are characterized by deterioration and can be damaged by environmental factors including ultraviolet rays, water, and shocks. In this paper as an urgent issue, we note that when using these products, in addition to paying attention to their expiration dates, precautions should be considered since deterioration may also progress due to prolonged attachment.
