Problems solved by technology

However, there are still defects in this technical solution. The driving motor needs to be reversed to drive the needle head fixing block to move back and forth, resulting in a relatively complicated control circuit and structure, so there is room for improvement.

Abstract

The invention discloses a needle pulling device of an automatic needle puller, comprising a bracket, a needle clamping forceps mounted on the bracket, a driving mechanism for driving the needle clamping forceps to reciprocate and a guide member capable of driving the needle clamping forceps to clamp tightly, wherein the driving mechanism comprises a slider, an eccentric wheel, a motor and a roller. The sliding block is connected with the needle clamping forceps, and the sliding block is slidably fitted on the bracket. The roller is provided with two rollers, and the two rollers are arranged onthe slider and arranged along the moving direction of the slider. The eccentric wheel is connected to the motor and is located between two rollers, and the side walls of the eccentric wheel are respectively in contact with the side walls of the two rollers. The structure and the control circuit of the invention are relatively simple and convenient to implement.

Description

technical field [0001] The invention relates to a needle pulling device of an automatic needle pulling machine. Background technique [0002] Injury waste refers to discarded medical sharps that can stab or cut the human body. The injuries caused by them are potentially dangerous. Once the sharps are infected by HIV, hepatitis B virus and other viruses, they may be infected when they are stabbed. Currently Most hospitals use common sharps boxes as storage containers. Since the sharps box does not have the function of separating the needles of infusion sets, and it can hold infusion tubes with needles, the amount of infusion blood vessels is not much, and the cost of transshipment and processing is high. During work, nurses need to cut off the needle of the infusion set with scissors, or separate the needle of the infusion set with bare hands, and only put the needle into the box. The steps are cumbersome, prone to needle stick injuries, and pose a safety hazard. [0003] Th...
