Bending device for recycling of medical syringe needle

Abstract

The invention relates to a bending device for recycling of a medical syringe needle, and belongs to the field of medical waste disposal. The bending device comprises a cannula, the cannula is internally matched with a telescopic rod, a U-shaped frame is fixed to the upper end of the telescopic rod, a lower shaft is fixed to the U-shaped frame, a movable wheel is coaxially mounted on the lower shaft, a bracket is fixed to the upper end of the cannula, a bearing is fixed to the upper end of the bracket, an upper shaft is fixed into the bearing, a fixed wheel is coaxially fixed to the upper shaft, the upper shaft and the lower shaft are parallel, the wheel surfaces of the movable wheel and the fixed wheel are tangent to each other, a lower groove is formed in the wheel surface of the movablewheel, the lower groove surrounds the movable wheel by a circle, an upper groove is formed in the wheel surface of the fixed wheel, the upper groove surrounds the fixed wheel by a circle, a rotary disc is coaxially fixed to the end of the upper shaft, a vertical plate is fixed to the circumferential face of the fixed wheel, a positioning hole is formed in the vertical plate, the diameter of the positioning hole is smaller than the diameter of a needle pin, when the vertical plate makes contact with the movable wheel, the fixed wheel is limited from rotating, and the common tangent line of theupper groove and the lower groove passes through the circle center of the positioning hole. A needle stem part of the needle can be bent, a needle stem is not bent to be broken, and meanwhile the bending position of the needle stem can be further adjusted so that the needle can be manufactured into other objects to be utilized.

Description

technical field [0001] The invention relates to a curved device for recycling needles of medical syringes, which belongs to the field of medical waste treatment. Background technique [0002] Currently, syringes are the most commonly used and one of the most used medical devices. In recent years, in order to control iatrogenic infectious diseases and avoid adverse consequences such as cross-infection, disposable sterile syringes have been widely used. However, the existing disposable syringes have defects such as being intact and reusable after use and having no safety device, and the needle is exposed after injection. Repeated use can easily cause virus spread and cross-infection. [0003] Since the needle stem of the needle is fixed on the pintle, and the metal content of the needle is very low, the recycling value of the needle is very low, and it is impossible to recycle the needle like ordinary metal recycling. Now for the disposal of needles, responsible medical uni...

Problems solved by technology

However, most medical units or processing units do not have a good supervision mechanism. The needles will be directly mixed with ordinary medical waste or even domestic waste, which is likely to stab people and become a hidden danger of virus transmission.
