Description
Technical field
The present invention relates to a kind of medical blood transfusion equipment and preparation method thereof, is a kind of blood transfusion apparatus dropping funnel bottle and preparation method thereof specifically.
Background technology
We know, the polyvinyl chloride low price, and high comprehensive performance generally is used to make disposable transfusion set.Along with clinical practice extensively and profoundly with the relevant medical science and technology development, it is found that there is potential safety hazard in pvc material itself, processing and serviceability on also have many defectives.Corvic can produce a spot of VCM in producing or processing, this compound has been proved to be carcinogen.In order to obtain the soft PVC goods, must use plasticizer in the processing, wherein, (DEHP) use of plasticizer is maximum for phthalic acid two (2-Octyl Nitrite), and this type plasticizer can get into soup, and gets into human body thereupon, is detrimental to health.For preventing that polyvinyl chloride from degrading in process, the compound that adds elements such as leaded, zinc and barium is usually made heat stabilizer, and in use, the heavy metal in these heat stabilizers possibly get into human body.The waste treatment of polyvinyl chloride medical disposable material difficulty is buried for a long time and is not degraded, and burns then to produce hydrogen chloride with toxic gases such as bioxin, contaminated environment.Polyvinyl chloride adds can decompose the generation hydrogen chloride gas man-hour, not only corrosion processing equipment, and threat operator ' s health.
Residual VCM, the DEHP plasticizer and the heat stabilizer of interpolation are not to be chemically bonded on the polyvinyl chloride molecule in the pvc material; The polyvinyl chloride blood transfusion apparatus in use; These little molecules can get into soup through modes such as diffusion, extractions, and then get into human body, are detrimental to health.In addition, because polyvinyl chloride is a polar material, the polyvinyl chloride blood transfusion apparatus of preparation has strong suction-operated to the part medicine, directly causes curative effect of medication to descend, and not only wastes medicine, also can make drug dose inaccurate, incurs loss through delay the patients ' recovery time.
In view of the problem of pvc material and blood transfusion apparatus existence thereof, the new material that all on the research and development price, can contend with both at home and abroad, performance satisfies the blood transfusion apparatus instructions for use with polyvinyl chloride.China's utility model patent 200420052781.0 discloses a kind of non-PVC transfusion device; China's utility model patent 200720029591.0 discloses a kind of disposable use TPO transfusion device; Chinese invention patent 200510014749.2 discloses a kind of radiation modified polyolefinic thermoplastic elastomer blending resin, and this resin can be used for replacing the PVC material that traditional disposable transfusion device adopts.So far, there are many deficiencies in non-PVC blood transfusion apparatus and the material thereof developed, can reduce: phenomenons such as pipeline entanglement can appear in (1) non-PVC blood transfusion apparatus surfaces of tacky in preservation or use.(2) mechanical property of non-PVC blood transfusion material is relatively poor, and the blood transfusion apparatus pipeline of preparation is in stressed easy deformation or fracture down.(3) adhesive property of non-PVC blood transfusion material is not good, and blood transfusion apparatus in use breakage, the phenomenon of leakage can occur.(4) non-PVC blood transfusion apparatus raw material and manufacturing cost are unfavorable for promoting the use of far above the polyvinyl chloride transfusion device.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art; Provide a kind of rational in infrastructure; Form simple, with blood and soup contact layer be the three-layer composite structure of non-PVC material, the interlaminar bonding performance is better; Good mechanical performance, cost are lower than blood transfusion apparatus dropping funnel bottle of non-PVC material and preparation method thereof.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of blood transfusion apparatus dropping funnel bottle; It is characterized in that: its dropping funnel bottle bottle wall is polyolefin/adhesive linkage/polyvinyl chloride three-layer composite structure, and internal layer is polyolefin layer, and skin is a polyvinyl chloride layer; The centre is an adhesive linkage; The polyolefin thickness of said dropping funnel bottle bottle wall is 0.1-0.25 mm, and the polyvinyl chloride layer thickness is 0.4-0.6mm, and the thickness of adhesive linkage is 0.02 mm-0.05 mm.
The preparation method of blood transfusion apparatus dropping funnel bottle according to the invention; It is characterized in that: with polyolefin, polyvinyl chloride and the adhesives of oven dry; Add respectively in polyolefin extruder hopper, polyvinyl chloride extruder hopper and the adhesive linkage extruder hopper by the desired weight ratio of bed thickness, extrude conduit through the co-extruding blow moulding machine head; The core rod type co-extruding blow moulding machine head that described co-extruding blow moulding machine head is three layers of concentric charging, the charging from the side of its ectomesoderm, intermediate layer, internal layer be linear feed from the center; Through regulating die orifice and the air blowing parameter that the co-extruding blow moulding machine head divides flow cone, confirm the wall thickness of dropping funnel bottle; Through regulating each extruder feed rate ratio, confirm polyolefin layer, polyvinyl chloride layer and the thickness of adhibited layer ratio of dropping funnel bottle; Then the conduit of extruding is introduced in the blow mold; With the three-layer composite structure dropping funnel bottle vane cooling that above-mentioned blowing forms, draw by carry-over pinch rolls, collect with the stainless steel pallet, obtain finished product.
The dropping funnel bottle inner surface of three-layer composite structure of the present invention is a polyolefin layer; The preparation method of said blood transfusion apparatus dropping funnel bottle utilizes three-layer co-extruded blowing unit; This unit is made up of three extruders, co-extruding blow moulding machine head and blow mold, adopts the coextrusion blow moiding method to obtain the product of three-layer composite structure.Against existing technologies, the surface that dropping funnel bottle of the present invention contacts with soup is a non-PVC material, and the plasticizer, heat stabilizer and the VCM that have solved in the polyvinyl chloride dropping funnel bottle get into soup, the problem that is detrimental to health.Overcome polyvinyl chloride dropping funnel bottle and drug response or absorption medicine simultaneously, made the prescription medication inaccurate, incured loss through delay the defective of rehabilitation duration.Polyolefin and pvc material that this dropping funnel bottle adopts have compatibility preferably; Preparation three-layer composite structure dropping funnel bottle and woven hose interlaminar bonding performance are better, and good mechanical performance is fit to high-frequency welding; Step of the present invention is simple; Method is reliable, and cost is far below non-PVC material, and large-scale promotion application suits.
