Abstract

The invention provides a process for assembling a safe intravenous needle, and belongs to the technical field of medical devices. The process comprises the following steps: step I, feeding a safe sliding sleeve; step II, feeding and assembling a needle seat; step III, feeding a shell; step IV: assembling the shell and the sliding sleeve; step V: adding adhesive on the needle seat for fixing; step VI: feeding a needle and dispensing adhesive; step VII: curing the adhesive; step VIII: siliconizing the tip of the needle; step IX: assembling a needle guard; step X: discharging a finished product. Compared with the prior art, the process provided by the invention can successfully assemble parts of the safe intravenous needle; through multiple times of material receiving of the parts in a staggered manner, the production efficiency can be greatly improved; a plurality of test items are added in the assembling process, and comprehensive defective screening is conducted on the parts and intermediate assemblies, so that discharging of defective products is reduced, and the finished product yield is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical venous needle, in particular to an assembly process of a safety venous needle. Background technique [0002] At present, the commonly used disposable venous needle is pulled out from the body of the infused person after use, which may cause danger or secondary injury to medical staff or patients. A Chinese patent (application number: 201410143686.X) discloses a The new safety venous needle includes a needle base, a needle cover, a hose, a connector and a needle head, the needle cover is set on the needle head, and the two ends of the hose are respectively connected with the connector and the needle holder, and the safety venous needle is also It includes a slider, a handle and a limit mechanism. The needle seat is cylindrical. One end of the needle seat is fixed and connected to the needle, and the other end is connected to the hose. On the seat, the length of th...
