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