Abstract

BACKGROUND: Needle-stick injuries accounts for a great proportion of all medical accidents in developing and undeveloped countries. The main cause of needle-stick accident injuries is the medical personnel's "recovering" the needle action after injection. OBJECTIVE: This study applies an electronic technique to the needling instrument for the purpose of automatically detaching the needle. The proposed method can effectively avoid needle-stick accident injury when "recovering" the needle. METHODS: The syringe needle auto-detaching device includes an abutment on which there is a turntable mechanism composed of a pedestal, a turn-table and a driving unit. A photo interrupter on the pedestal detects the rotational angle of the turntable and controls the stepping motor through a control circuit. An optical sensor is located on the upper end of the sensing mechanism. When the syringe is inserted into the syringe plughole the exposed portion of the needle will be detected by the optical sensor. After the syringe is placed into the plughole, its needle will be detected by the sensor. At this time the needle will be detached from the syringe and automatically fall down into the needle collection box. RESULTS: The syringe needle auto-detaching device was fatigue tested for an extensive period of time (A group: 1000 times/day for 3 ml, B group: 1000 times/day for 5 ml, C group: 1000 times/day for 3 ml and 5 ml staggered, D group: 1000 times/day for 3 ml and 5 ml randomized). The needle and syringe detachment rates were 100% in all test groups. CONCLUSIONS: The syringe needle auto-detaching device developed in this study, in that the clinician performs only one step to dispose a needle. Six syringe needle sets can be managed sequence second by second. The proposed device without all of the risk factors of the traditional syringe needle detachment device.
