An automatic feeding method and device for medical plastic needles

Abstract

The invention provides an automatic feeding method and an automatic feeding device of a medical plastic needle, which belong to the technical field of medical appliances and solve the problems of low assembly efficiency and the like of the existing plastic needle. The automatic feeding method of the medical plastic needle comprises the following steps of a, material storage, b, material sieving, c, material hanging, d, material sorting and e, material discharge. The automatic feeding device of the medical plastic needle comprises a vibration feeding disc, wherein the bottom of the vibration feeding disc is provided with a material storage cavity, an annular material conveying passage is arranged on the vibration feeding disc, the material conveying passage is in inclined arrangement, in addition, the lowest end of the material conveying passage is communicated with the material storage cavity, the other end of the material conveying passage is provided with a material discharge part, a material sieving part, a material hanging part and a material sorting part are sequentially arranged on the material conveying passage along the moving direction of the plastic needle, the bottom of the material hanging part and the bottom of the material sorting part are respectively provided with a guide groove for embedding a penetrating part of the plastic needle, a discharging air nozzle corresponding to the material hanging part is arranged on the vibration feeding disc, and a material sorting air nozzle corresponding to the material sorting part is arranged on the feeding disc. The automatic feeding method and the automatic feeding device of the medical plastic needle have the advantages that the conveying efficiency is high, the automation degree is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an assembly of sterile medical devices, in particular to a method for feeding plastic needles in the automatic assembly of disposable sterile infusion sets and an automatic feeding device thereof. Background technique [0002] With the improvement of social living standards, infusion as an important treatment method is more widely used in clinical cases. Infusion is a large dose of injection (more than 100ml at one time) injected into the body by intravenous infusion. During the infusion, the infusion speed is adjusted through the infusion set, and it enters the vein continuously and stably to replenish body fluids, electrolytes or provide nutrients. . [0003] In the medical infusion industry, disposable infusion sets have been widely used due to their convenience, safety and hygiene. Disinfection is not required during infusion, and the user only needs to unpack the pac...
