Bottle-pricking needle feeding mechanism

Abstract

The invention provides a bottle-pricking needle feeding mechanism and belongs to the technical field of medical equipment. The bottle-pricking needle feeding mechanism comprises vibrating discs, a straight vibrating plate and a staggered material receiving device. One end of the straight vibrating plate is connected with the vibrating discs and the other end of the straight vibrating plate is connected with the staggered material receiving device. Bottle-pricking needle material ways for bottle-pricking needles to arrange and move forward are arranged on the straight vibrating plate. A carrier circulating device is arranged on the other side of the staggered material receiving device and the carrier circulating device comprises bottle-pricking needle carriers used for receiving and transferring the bottle-pricking needles. A bottle-pricking needle placing device, which is capable of clamping the bottle-pricking needle from the staggered material receiving device and conveying the bottle-pricking needles onto the bottle-pricking needle carriers, is arranged on the carrier circulating device. The bottle-pricking needle feeding mechanism further comprises a bottle-pricking needle overturning and shaping device which is arranged in the staggered material receiving device. A material taking device, used for taking the bottle-pricking needles out of the straight vibrating plate and placing the bottle-pricking needles onto the staggered material receiving device, is arranged between the straight vibrating plate and the staggered material receiving device. The feeding mechanism is simple and ingenious in design, high in automation degree, capable of guaranteeing the orientation consistency of air inlet pipe ports of the bottle-pricking needles and convenient for assembly of bottle-pricking needles.

Description

technical field [0001] The invention belongs to the technical field of medical machinery, and relates to a bottle insertion needle feeding mechanism. Background technique [0002] The bottle insertion needle is a necessary component of the infusion set in the intravenous infusion. It is used to puncture the bottle stopper to make the medicine flow out from the bottle insertion needle into the infusion catheter. It is also called a plastic needle. The bottle insertion needle generally includes a needle base, acupuncture, an air inlet nozzle and a liquid outlet nozzle. The inlet nozzle is generally arranged in the middle of the needle holder and is perpendicular to the needle holder. In the upper and lower positions, the needle holder is also provided with a needle holder platform perpendicular to the needle holder and the air inlet port, which is used to assist the hand to apply force to insert the acupuncture into the infusion bottle.

Problems solved by technology

[0005] Although the above-mentioned device can realize the material transfer of the bottle-inserting needle to a certain extent, in reality, when the bottle-inserting needle is discharged from the direct vibration plate, it cannot ensure that the direction of the inlet pipe of the bottle-inserting needle is in the same direction, and the next step is directly carried out. Operation will lead to subsequent assembly failure, resulting in waste of human and material resources
