Description
Technical field
The present invention relates to a kind of medicinal liquid packaging bag and irritate the liquid method, be specifically related to a kind of three chamber bags and filling liquid method thereof that is used for the splendid attire medicinal liquid.
Background technology
At present; In clinical practice; When patient imported multiple different transfusion if desired simultaneously, what generally take was before use with this multiple single Different products, the aseptic ingredients chamber of setting up specially in hospital; Under aseptic condition, multiple different single variety is taken out mix homogeneously, again the medicinal liquid of mixing is imported human body.Yet " aseptic " is from the definition absolute concepts of saying so, but regrettably, in today of Science and Technology high development, absolutesterility is not promptly accomplished, can't confirm yet.More than, this mixed method has increased the probability of the contaminated microorganism risk of medicine.Simultaneously, because of build aseptic ingredients chamber, operating cost is higher, set up relatively difficulty of aseptic ingredients chamber for general hospital.Also hindered simultaneously the popularization of mixing infusion model with treatment advantage.And repeatedly get it filled and will cause puncture plug repeatedly, so just might cause the repeatedly risk of friction generates particle contamination infusion products of plug and contact pin, production, use cost are all than higher simultaneously.
Therefore, occurred can three kinds of different medicinal liquids of splendid attire three chamber bags, be three chamber bags of 201110021775.3 like application number, the medicinal liquid of three chambers is mixed infuses.Three chamber bags of the prior art are as shown in Figure 1; Form by medicinal liquid inner bag and outer bag; Its herb liquid inner bag by the radian of tubaeform liquid feeding mouth 1, band opening point a little less than welding rod 2, welding protruding point 3, hang hole 4, the first side room medicinal liquid cavity 5, middle chamber medicinal liquid cavity 6, the second side room medicinal liquid cavity 7, three chamber bag sides 8, bag bag angle, three chambeies 9, solder up 10, loading plug 11, dosing plug 12, jig 16 is formed; Around the medicinal liquid inner bag is real welding rod, and welding protruding point 3 is arranged on the inboard of the real welding rod of upside and in the inner chamber of medicinal liquid inner bag, protrudes; Outer bag is opened mouthfuls 15 by the real welding rod of outer bag 13, outer bag 14, outer bag and is formed.During use, open mouthfuls 15 from outer bag outer bag 13 torn, take out the medicinal liquid inner bag, open welding rod 2 a little less than each radian from weak weldering opening point with external force, can be with three kinds of medicinal liquid mixings uses.Real welding rod is meant the Type of Welding of no longer opening after the film material welding to bag, and its weld force is bigger; Weak welding rod is meant after the welding of film material, can temporarily bag film material be welded together, and apply under the enough big external force effect, can be with opening by weak welding rod.

2, jar liquid mouth 1 diameter at existing bag solder up 10 places, three chambeies is generally between 10mm to 20mm; Toward the first side room medicinal liquid cavity 5 and the second side room medicinal liquid cavity, 7 filling liquid the time; The medicinal liquid of fill head can remain on the film material of jar liquid mouth, like this, and when being encapsulated into solder up 10 in jar liquid mouth 1; Cause poorly sealed, thereby influence the quality of medicinal liquid.
3, because existing three chamber bags need the amount of liquid medicine of splendid attire all bigger; But its hang 4 tops, hole apart from the limit portion dimension D of medicinal liquid inner bag generally between the 5mm to 8mm; Cause in infusion process, cause three chamber bags to come off, increased the risk of infusion process from hook.
4, in existing three chamber bags, after transfusion is accomplished, often cause the part medicinal liquid to remain in the bag and can not export fully.
5, be simultaneously toward the first side room medicinal liquid cavity 5, middle chamber medicinal liquid cavity 6 and the second side room medicinal liquid cavity, 7 filling liquid in irritating the liquid process; Like this; In medicinal liquid in the chamber medicinal liquid cavity 6 can the first side room medicinal liquid cavity 5, the second side room medicinal liquid cavity 7 of its both sides be formed and stretch, the first side room medicinal liquid cavity 5 and the second side room medicinal liquid cavity 7 are drawn close toward centres, cause the jar liquid mouth of the first side room medicinal liquid cavity 5, the second side room medicinal liquid cavity 7 to be out of shape; Like this; When solder up 10 being encapsulated in the liquid feeding mouth 1 of the first side room medicinal liquid cavity 5, the second side room medicinal liquid cavity 7, cause poorly sealed, thereby influence the quality of medicinal liquid.
