Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of precision liquid medicine lucifuge filter and manufacture method thereof.
Background technology
At present, the lucifuge filter of clinical use, in order to reach the requirement of lucifuge, major measure has: (1) uses lightshade cover to cover on the liquid medicine filter that does not possess the lucifuge performance, to reach the effect of lucifuge, the problem that exists is the transfusion device specification difference owing to each manufacturer production, and version also differs, and causes the difficulty of lightshade cover processing and the compatibility of use; (2) add the lucifuge agent in the employing raw material that has, the mode that has even adopt the interpolation common dye reaches the purpose of lucifuge, therefore, in infusion process, the lucifuge agent has inevitably and is dissolved into to a certain extent in the medicinal liquid, makes the lucifuge agent enter human body, works the mischief.Existing manufacture method is the common injection machine injection moulding of single head single layer structure, or the method for outer envelope photosphere, and the lucifuge agent of single layer structure can be dissolved in the medicinal liquid when transfusion, works the mischief, and outsourcing Lacquer finish one is trouble, the 2nd, and the lucifuge effect is bad.
Summary of the invention
The objective of the invention is to overcome the unsafe problem of prior art lucifuge filter, provide a kind of lucifuge effective, have precision liquid medicine lucifuge filter and the manufacture method thereof of filtration.
For achieving the above object, the technical scheme taked of the present invention is:
A kind of precision liquid medicine lucifuge filter, comprise filter cover, filter membrane, filter lower cover, described filter cover and filter lower cover fasten mutually and weld together, described filter cover is formed by double injection, the loam cake internal layer is the water white transparency layer, and loam cake is outer for being added with the lucifuge layer of lucifuge agent, and filter cover has liquid feeding end, filter cover is provided with at least one venthole, the intrinsic hydrophobic membrane in venthole place; Described filter lower cover is formed by double injection, the lower cover internal layer is the water white transparency layer, lower cover is outer for being added with the lucifuge layer of lucifuge agent, the filter lower cover is provided with liquid outlet, filter membrane is between filter cover and filter lower cover, form a medicinal liquid cavity between filter membrane and the filter cover, constitute a filter chamber between filter membrane and the filter lower cover.
Described hydrophobic membrane utilizes ultrasonic welding machine to be welded on the inwall of filter cover.
Cover under the described filter and be provided with the support that supports filter membrane, filter membrane and filter cover, filter lower cover use ultrasonic welding machine integrally welded.
Described filter cover has 2-8 venthole.
The normal pore size of described filter membrane is 5 μ m or 3 μ m or 2 μ m.
The manufacture method of precision liquid medicine lucifuge filter comprises the steps: that A is injection molded into required form with filter cover, filter lower cover with the double end injection machine; Behind the B injection molded, moulding is warmed to 80 ℃～110 ℃, is incubated 12～24 hours, natural cooling; C is welded on hydrophobic membrane on the filter cover relevant position; The D filter lower cover that is placed on that filter membrane is smooth has on the support that supports filter membrane, fastens then to go up filter cover; It is integrally welded that E will fasten good filter cover, filter lower cover and filter membrane.
The present invention utilizes the double end injection machine, the injection moulding double-decker, double-deck internal layer does not have the lucifuge agent, the lucifuge layer does not directly contact with medicinal liquid, the lucifuge agent can not dissolved in the medicinal liquid and be gone when transfusion, stopped the harm of lucifuge agent to medicinal liquid, simultaneously the optional position of filter can aerofluxus, farthest lowered the resistance that big flow transfusion produces, can guarantee the needs of clinical big flow transfusion, long-time result of use is more obvious, the product structure advantages of simple, lucifuge is effective, and is safe and reliable, and preparation technology is simple simultaneously, the degree of being connected firmly of filter and stability are improved, this technology has been avoided adopting conventional bonding agent to connect the pollution problem that brings, and behind the injection molded of the present invention, moulding is warmed to 80 ℃～110 ℃, be incubated 12～24 hours, natural cooling is mainly used in the stress except material internal, cracking phenomena can not take place after making the product welding.
