Abstract
The utility model discloses a multilayer co-extrusion film infusion bag. The inner surface of a protecting bag of the infusion bag is closely attached to the outer surface of a medicament packaging bag, a multilayer co-extrusion film is adopted for the medicament packaging bag, and a medicine adding infusion opening is welded to the medicament packaging bag through a welding face; the welding face is a flat opening, and a transverse groove and a boss are arranged on the surface of the welding face; a soft plug expansion buffer chamber is arranged in the medicine adding infusion opening; a sealing cover body is arranged on an end opening of the medicine adding infusion opening. A vacuum structure is arrange between the protecting bag and the medicament packaging bag, the inner surface of the protecting bag is closely attached to the outer surface of the medicament packaging bag; whether micro holes exist in the medicament packaging bag or not can be observed with the naked eyes. The transverse groove and the boss are arranged on the surface of the welding face, and therefore welding stability and airtightness of the welding face are guaranteed. The sealing cover body is arranged on the medicine adding infusion opening, and therefore it is guaranteed that in the process of production and carrying of the infusion bag, the medicine adding infusion opening does not make contact with the outside, no bacteria are generated, medicine adding and infusion operation can be performed after the sealing cover body is removed, and disinfection is not needed. The soft plug expansion buffer chamber is arranged below a soft plug, and therefore chip falling of the soft plug is prevented.
Description
Technical field
This utility model relates to a kind of transfusion transfusion bag, is field of medicaments.
Background technology
Infusion treatment disease is a kind of therapeutic modality conventional in modern medical service.The mode that the nutrient that needed by human body in therapeutic process is wanted or medicine are directly inputted by intravenous drip, completes human body is carried out to administration, then, by the blood circulation of human body self, medicine or nutrition is delivered to Whole Body.The manner of packing of transfusion, by initial glass bottle packaging, is improved to plastic bottle packing, then by the improvement of technology, has been upgraded to the bag type package of present optimum.Bag type package is disposable use, and it is safe, and in infusion process, not needing to introduce extraneous air increases pressure, can complete transfusion.
Existing bag-type infusion is packed its shortcoming:
What 1, adopt because of transfusion bag is soft bag type package material, and the quality of its material is soft, in the course of processing, may occur that the material processing has micropore phenomenon, or in transportation, move in process, all likely Drug packing is damaged.These reasons can cause producing in transfusion bag micro-, and these micropores are very tiny, and naked eyes cannot be observed; Medicinal liquid can not exosmose at short notice, or in the process of exosmosing, has produced volatilization, and naked eyes cannot be found.The harm of micropore is, micropore will form a passage outward with bag in transfusion bag, and airborne antibacterial can enter in bag by this passage, and this destroys the medicinal liquid in bag.
2, in use, because safe and sanitary needs, requirement carries out disinfection to the infusion port of transfusion bag, this can cause some inconvenience to nurse's work, there are on the market now some Easy-folding transfusion lids, the use that in use infusion port front end fractureed, without sterilization, but its production cost of this mode is higher.
3, in liquid feeding infusion port, install and insert the cork that transfusion needle is used, when penetrating cork with needle point, by friction, cork can produce bits, falls bits and falls in the medicinal liquid of transfusion bag and infusion bottle, pollutes medicinal liquid.
Utility model content
Vacuum type layer co-extrusion film infusion bag; comprise protective bag 8 and kit pack, kit pack 7 is inserted in protective bag 8, in kit pack, is welded with medicine-adding infusion mouth 5; between protective bag and kit pack, be vacuum structure, the intimate laminating of protective bag inner surface and kit pack.Described kit pack is PP TYPE, and PP TYPE is comprised of three to seven layer of material pressings, comprises strength layer 12, anticorrosive coat 11.
Medicine-adding infusion mouth lower end is provided with solder side 6, and medicine-adding infusion mouth is by solder side and kit pack welding; Solder side 6 is flat mouthful, and on surface, is provided with transverse concave groove and boss.
Vacuum type layer co-extrusion film infusion bag as above, further illustrate into, cork installation room and cork expansion buffer chamber 12 are set in medicine-adding infusion mouth, cork 9 is set in cork installation room, cork expansion buffer chamber is arranged on cork installation room below.
On the port of medicine-adding infusion mouth, be provided with sealing cover body 4, described sealing cover body is plastic foil.
Vacuum type layer co-extrusion film infusion bag as above, further illustrate into, the bag mouth of protective bag is provided with vacuum drawn mouth 2, in order to by extracting vacuum between the pack of protective bag and kit.
Protective bag surrounding has edge band 3; The width of its edge band is 3-5mm, and vacuum drawn mouth 2 places are provided with tears bag breach 1; Described kit pack 7 is non-PVC bag.
Described cork expansion buffer chamber 10 degree of depth are 2-6mm.
Beneficial effect:
Between protective bag and kit pack, it is vacuum structure; The intimate laminating of protective bag inner surface and kit pack; If there is kit pack, there is micropore, can form water mark in the joint place between protective bag and kit pack, with the naked eye can observe.
The surface of seam face is provided with transverse concave groove and boss, has guaranteed the firm and airtight of its seam.Owing to having adopted groove and boss structure, after seam, be equivalent to form multi-stage sealed, guaranteed sealing.
On medicine-adding infusion mouth, be provided with sealing cover body, in the production of transfusion bag, move in process, guaranteed that medicine-adding infusion mouth does not contact with the external world, do not produce antibacterial, sealing cover body just can dosing and transfusion operation after taking off, need not sterilize.
Vacuum drawn mouth place is provided with tears a bag breach, easy to use.
Described protective bag is PP TYPE, and its material is good, after extracting vacuum, can keep for a long time the vacuum pressure in bag.Situation in the convenient observation bag of simultaneously transparent bag.
The below of cork arranges the swollen surge chamber that rises of cork, and when penetrating cork with needle point, cork has enough large swollen space of rising downwards, reduces the friction of needle point to cork, prevents that cork from falling bits.Moreover, when cork still falls in the situation of bits, fall bits and can drop in cork surge chamber, reduce the pollution to medicinal liquid.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is medicine-adding infusion mouth partial sectional view.
Fig. 3 is PP TYPE structure chart.
The specific embodiment
This utility model is implemented in the following way:
One, make kit pack 7, and dosing.
Kit pack 7 is PP TYPEs, and the packaging material of buying, all through aseptic packaging, before entering into workshop, are disinfected.After cutting is folding, with medicine-adding infusion 5 seam.Medicine-adding infusion mouth 5 places have been provided with sealing cover body 4, and have carried out pre-sterilization.
After seam, start to carry out medicament injection.
Two, be inserted in protective bag.
The Drug packing bag that has injected medicament is encased in protective bag 8.Carry out extracting vacuum simultaneously.Then to the integral body sterilization that carries out disinfection.
Protective bag 8 is through seam edge in advance below, in the later stage, during extracting vacuum, can have enough intensity to bear vacuum pressure.Then cut and tear bag breach 1.
Three, use.
In use, by perusal, can see that whether kit packs perforation.
In the situation that determining this kit pack without leakage, use.During use, along tearing a bag breach, tear protective bag, take out kit pack, the plastic foil of opening gently on medicine-adding infusion mouth just can directly be used (without sterilization).Extremely facilitate the places such as the operating room of abrasive or salvage at scene.
Plastic foil on medicine-adding infusion mouth can be used and the non-PVC of kit pack with material.
