Abstract
Provided is a peripheral nervous stimulating needle manufacturing process. The peripheral nervous stimulating needle manufacturing process comprises the following steps: painting teflon on the surface of an entry needle tubing with a metal needle seat and forming an insulation layer, preserving 5-10 millimeters on the root portion of the needle tubing not to proceed insulating process; connecting a wire with the root portion of the needle tubing without painting the insulation layer; molding an outer sleeve of the needle seat in an injection mode, and then arranging the outer sleeve of the needle seat on an injecting needle in a sleeved mode; injecting glue between the outer sleeve of the needle seat and the metal needle seat; starting cleaning process for the injection needle tubing with the insulation layer and the outer sleeve of the needle seat; after processing, and starting sterilization after packaging the peripheral nervous stimulating needle. The peripheral nervous stimulating needle manufacturing process can not produce pollution to the injection needle and the wire, thereby relieving subsequent cleaning workload; the conditions of dropping the insulation layer and damage of the wire due to high temperature can not occur in the process of assembling and glue injecting, so that working efficiency and quality rate of productions are improved, in the meantime the peripheral nervous stimulating needle manufacturing process can be achieved by reworking, and therefore use ratio of components is improved, and manufacturing cost is lowered.
Description
Technical field
The present invention relates to a kind of production technology, particularly a kind of peripheral nerve stimulation pin production technology of using utensil in treatment nerve block and local accurately location anesthesia.
Background technology
At present the conventional production process of peripheral nerve stimulation pin is: first with the needle tubing insulation processing of common metal entry needle, rear tape insulation layer entry needle is connected with wire, form the line entry needle, the line entry needle is put into the injection mold injection mo(u)lding, clean again at last, pack, sterilizing gets final product.
There is following shortcoming in the injection molding process of this production technology: a. tape insulation layer entry needle and wire accessory vulnerable to pollution; B. insulating barrier is vulnerable to the extruding of injection mold and comes off; C. wire and entry needle forming process are fragile; D. needle point easy damaged, tough easy sideslip; E. can not contrary operation due to injection moulding process, no matter any defective products of wire or needle point therefore occurs, can cause that all product other accessory except wire all scraps, and the tape insulation layer entry needle of product and wire are main accessory and the cost major part of product, and therefore the meeting loss is very large in manufacturing process.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of method reasonable, prevents contamination of products, damage, greatly improves the peripheral nerve stimulation pin production technology of product percent of pass.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of peripheral nerve stimulation pin production technology, is characterized in, its step is as follows:
(1) form insulating barrier coating politef with the syringe needle tube surface of metal needle stand, the needle tubing root keeps 5-10mm and does not carry out insulation processing;
(2) wire is connected with the needle tubing root that is not coated with insulating barrier;
(3) needle stand overcoat injection mo(u)lding; Then with the needle stand coat suit on entry needle;
(4) inject glue between needle stand overcoat and metal needle stand, further fixedly needle stand overcoat and metal needle stand; (5) syringe needle tube and the needle stand overcoat of tape insulation layer are carried out clean; After handling, with peripheral nerve stimulation pin packing, sterilizing gets final product.
The injection mo(u)lding of needle stand overcoat can be adopted any process injection mo(u)lding in prior art.
Compared with prior art, the present invention has following advantage:
A. production technology is reasonable, can not produce pollution to entry needle and the wire of tape insulation layer in whole production process, has therefore alleviated the workload of postorder cleaning;
B. in two operating procedures that the needle stand coat suit is fixed with glue on entry needle, tape insulation layer entry needle and wire can not touch the metals such as injection mold, can not stand high pressure and pyroprocess yet, therefore the damage with tape insulation layer entry needle and wire has dropped to minimum, can not occur namely that insulating barrier comes off and the situation of wire Yin Gaowen equivalent damage, improve accepted product percentage and the production efficiency of product;
C. in process of production, the wire if the needle stand overcoat frays because be reversible with needle stand coat suit this process on entry needle, can by opening needle stand overcoat restringing and/or doing over again to realize, improve the utilization rate of accessory;
D. owing to can manually immediately adjust tough angle of needle point in the process that is fixed with glue at the needle stand coat suit on entry needle, reduced the defective products rate of tough sideslip;
E. needle stand overcoat injection molding process owing to not being with pincers spare, has therefore improved injection mo(u)lding efficient and accepted product percentage, and in the defective products workinprocess cost of injection moulding process generation simultaneously, proportion is very low, less than 1%, has therefore reduced greatly cost.
The specific embodiment
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not consist of its Copyright law.
Embodiment 1, a kind of peripheral nerve stimulation pin production technology, and its step is as follows:
(1) form insulating barrier coating politef with the syringe needle tube surface of metal needle stand, the needle tubing root keeps 5-10mm and does not carry out insulation processing; (2) wire is connected with the needle tubing root that is not coated with insulating barrier; (3) on injection-moulding device separately with the injection mo(u)lding of needle stand overcoat; Then with the needle stand coat suit on entry needle, make the needle tubing of tape insulation layer pass the needle stand overcoat, the metal needle stand of entry needle is partly stayed needle stand overcoat rear end, wire and needle tubing joint are wrapped in the needle stand overcoat; (4) inject glue between needle stand overcoat and metal needle stand, glue can be normal temperature cure glue, further fixedly needle stand overcoat and metal needle stand; (5) can use cotton ball soaked in alcohol to carry out clean to syringe needle tube and the needle stand overcoat of tape insulation layer; After handling, the peripheral nerve stimulation pin is packed and sterilized with oxirane.
