Abstract
An aseptic medical packing container is made up of Z9550, B2005 and SBS through mixing, stirring, fusion, drawing, cutting, granulating, injection moulding, inspection, assembly, and sealing. The combined structure of hole, internal and external cover and rubber packing is substituted for original tubular structure at charge position. The full-enclosed packing contained made of polyolefine without plasticizer features low adsorption and oxygen permeability, no dissolving out, and no cross infection.
Description
The present invention relates to a kind of polyolefine aseptic packing bag for medical use and preparation method thereof, relate to the totally enclosed type plastics medical package container of the outer infusion solution of the outer intestinal of a kind of disposable fill, storage and infusion, flushing liquor, dialysis solution and non-enteral nutrition product etc. and the preparation method of this container specifically.
At present; the domestic and international more packing bag for medical use of clinical practice; generally can be divided into PVC liquid bag and non-PVC liquid bag; its fill, infusion partly mostly are tubular structure, and the packing bag for medical use of this tubular structure is at paracentesis area unprotect device, and point of puncture can not guarantee sealing; the fluid seepage phenomenon appears in regular meeting; perforator can not firmly fix under certain pulling force, even the shape of some packing do not conform to the requirement of transfusion, has a large amount of liquid residues during clinical practice.
In addition, in the past few decades, the transfusion package material of China carries out the transition to PVC plastic bag and polyolefin plastics bottle by vial, the packing infusion vessel that these packaging material are made, the pollution that pyrogen reaction, cross infection and cross-ventilation cause has appearred to some extent through clinically prolonged application proof, moreover the PVC material can produce a large amount of harmful gass when destroying, and causes the severe contamination of environment, and promptly the packing infusion vessel of current packaging material awaits improving.
The totally enclosed type plastics packing bag for medical use of the object of the present invention is to provide that a kind of do as one likes can be stablized, the polyolefine material of high temperature resistant (121 ℃), aging resistance, no plasticizer being made is to overcome the deficiencies in the prior art.
The bag of product polyolefine aseptic packing bag for medical use of the present invention, Kong Zui, exterior and interior cover main component are polyolefin, and performance can reach the testing standard of ASTM, and polyolefin is nontoxic, have good moisture-resisting degree and sealing intensity.
The object of the present invention is achieved like this: it mainly is made up of raw materials such as Z9550, B2005 and SBS, pass through mixing, stirring, fusion, tie rod, cutting, pelletize, injection mo(u)lding, check, assembling, check, be sealed to form, it is characterized in that it is the packing bag for medical use that is prepared by following weight percentages
Hole mouth and inner cap:
Major ingredient:
Z9550 70～90％
Adjuvant:
B2005 10～30％
Enclosing cover:
Major ingredient:
Z9550 55～75％
Adjuvant:
B2005 8～23％ SBS 12～32％。
The preparation method of polyolefine aseptic packing bag for medical use of the present invention is characterized in that:
1. be purchased and the raw material of the said components of weighing,
2. mix,
3. fusion (this moment, temperature can reach 250～260 ℃),
4. cooling
5. tie rod cutting,
6. material is transferred on the comminutor, produces mix homogeneously, tiny granule
7. above-mentioned transfer of granules is passed through mould molding to injection molding machine, temperature reaches about 230 ℃,
8. the product of molding is lowered the temperature,
9. through supporting assembling, sealing, storage after the assay was approved, promptly get product of the present invention.
Its feature also is: the raw material that described hole mouth, exterior and interior cover are selected for use is nontoxic, and nonirritant meets the material of medical standard.
Shape of product of the present invention and structure are to realize like this, it mainly is made up of bag (2), hole mouth (3), inner cap (4), butyl rubber pad (5), enclosing cover parts such as (6), it is characterized in that bag (2) is connected with an end heat seal of hole mouth (3), the other end difference gland inward upper cover (4) and butyl rubber pad (5) back of hole mouth (3) are in aggregates with enclosing cover (6) heat seal.
Its feature is that also described bag (2) is provided with suppending hole (1) and high frequency sealing edges (7).
Its feature is that also enclosing cover (6) is provided with draw ring (8).
The present invention compared with prior art, it is simple in structure, and is reasonable in design, with low cost, the totally enclosed type plastics medical package container of be that do as one likes can be stablized, the polyolefine material of high temperature resistant (121 ℃), aging resistance, no plasticizer being made, its adsorptivity is little, no stripping phenomenon, OTR oxygen transmission rate is low, clinical practice is convenient, does not need cross-ventilation, has avoided pyrogen reaction, cross infection and pollution, do not have harmful gas during destruction and produce, overcome the deficiencies in the prior art.
Further specify the present invention below in conjunction with accompanying drawing
Accompanying drawing is an overall structure sketch map of the present invention
Among the figure: 1, suppending hole, 2, bag, 3, Kong Zui, 4, inner cap, 5, the butyl rubber pad, 6, enclosing cover, 7, high frequency sealing edges, 8, draw ring.
Referring to accompanying drawing, shape of product of the present invention and structure are on existing packing bag for medical use basis, the bag shape is improved slightly, the periphery radian strengthens, according to clinical practical application, can be divided into 250ml, 500ml, three specifications of 1000ml, its structure is the tubular structure that substitutes infusion site with hole mouth, exterior and interior cover and rubber blanket combination back
It mainly is made up of bag (2), hole mouth (3), inner cap (4), butyl rubber pad (5), enclosing cover parts such as (6), described bag (2) is provided with suppending hole (1) and high frequency sealing edges (7), it is characterized in that bag (2) is connected with an end heat seal of hole mouth (3), the other end difference gland inward upper cover (4) and butyl rubber pad (5) back of hole mouth (3) are in aggregates with enclosing cover (6) heat seal, promptly be hermetically sealed shape, enclosing cover (6) is provided with draw ring (8), enclosing cover (6) is protected dosing and site of puncture as protector; It is dosing and infusion site that butyl rubber pad (5) has certain elasticity; Inner cap (4) has the effect that prevents that medicinal liquid and enclosing cover (6) from contacting with butyl rubber pad (5); Hole mouth (3) has certain supporting role in a tubular form, is the directly position of medicinal liquid turnover.
