Abstract
The utility model discloses a negative pressure type transfusion bag. The inner surface of a protective bag is tightly attached to the outer surface of a medicine package bag, a medicine adding transfusion port is welded to the medicine package bag through a flat solder side, a transverse groove and a boss are arranged on the surface of the solder side, a soft plug expansion buffer chamber is arranged in the medicine adding transfusion port, and a sealing cover is arranged in the mouth of the medicine adding transfusion port. The space between the protective bag and the medicine package bag is of a negative pressure structure, and the inner surface of the protective bag is tightly attached to the outer surface of the medicine package bag; whether the medicine package bag is provided with a tiny hole or not can be observed with eyes; the surface of the solder side is provided with the transverse groove and the boss, so that soldering firmness and leakproofness of the solder side are ensured. As the medicine adding transfusion port is provided with the sealing cover, it is ensured that the medicine adding transfusion port does not make contact with the outside world in the production and carrying processes of the transfusion bag, and no germ is generated. The operations of medicine adding and transfusion can be carried out after the sealing cover is opened, and disinfection is not needed. The soft plug expansion buffer chamber is arranged below a soft plug, so that the soft plug is prevented from generating chips.
Description
Technical field
This utility model relates to a kind of transfusion transfusion bag, is field of medicaments, especially a kind of transfusion bag of double casing.
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:
1, because of transfusion bag adopt be soft bag type package material, the quality of its material is soft, in the course of processing, may occur that the material processing has micropore phenomenon, or transport, 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, require the infusion port of transfusion bag to carry out disinfection, 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, in the time 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
Negative-pressure type transfusion 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 negative pressure structure, the intimate laminating of protective bag inner surface and kit pack.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 is provided with transverse concave groove and boss on surface.
Negative-pressure type transfusion 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.
Negative-pressure type transfusion bag as above, further illustrate into, the bag mouth of protective bag is provided with negative pressure extracting mouth 2, in order to will protective bag and kit pack between extract negative pressure.
Protective bag surrounding has edge band 3; The width of its edge band is 3-5mm, and negative pressure extracting mouth 2 places are provided with tears bag breach 1; Described protective bag 8 is transparent PVC bag; 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 negative pressure structure; The intimate laminating of protective bag inner surface and kit pack; There is micropore if there is kit pack, 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 ensured the firm and airtight of its seam.Owing to having adopted groove and boss structure, after seam, be equivalent to form multi-stage sealed, ensure sealing.
On medicine-adding infusion mouth, be provided with sealing cover body, in the production of transfusion bag, move in process, ensured 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.
Negative pressure extracting mouth place is provided with tears a bag breach, easy to use.
Described protective bag is transparent PVC bag, and its material is good, after extraction negative pressure, can keep for a long time the negative pressure 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 in the time 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.

Fig. 3 is medicine-adding infusion mouth structure figure.
Detailed description of the invention
This utility model is implemented in the following way:
Negative pressure of the present utility model refers to the negative pressure extracting between protective bag and kit pack, and its negative pressure value is-0.1P.
One, make kit pack 7, and dosing.
Kit pack 7 is the plastic material matter of non-PVC, and the packaging material of buying, all through aseptic packaging, entering into before 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.Extract negative pressure simultaneously.Then to the entirety sterilization that carries out disinfection.
Protective bag 8, through seam edge in advance below, while extracting negative pressure, can have enough intensity to bear negative pressure pressure in the later stage.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.When use, tear protective bag along tearing a bag breach, take out kit pack, the plastic foil of opening gently on medicine-adding infusion mouth just can directly use (without sterilization).Extremely facilitate the place such as operating room or salvage at scene of abrasive.
Plastic foil on medicine-adding infusion mouth can use and the transparent PVC of protective bag 8 with material, also can use and the non-PVC of kit pack with material.
