Abstract
The utility model discloses a single hard tube interface for preventing leakage of an infusion bag. The interface comprises an infusion port and two-wing welding surfaces, wherein the infusion port comprises an infusion port top and an infusion port bottom; and the two-wing welding surfaces comprise round clamping necks, two wings of the interface, large filleted corners of the two wings, small filleted corners of the two wings, interface necks, interface welding top surfaces and interface wing filleted corners. The single hard tube interface for preventing leakage of the infusion bag has the advantage of reducing the problem of seriously stretching a membrane material in the membrane material welding process due to overlarge welding size, thereby ensuring the toughness of the membrane material at the position where the interface is connected with the membrane material, and effectively reducing the welding leakage ratio of 90 percent of interface parts. Meanwhile, not only is the cost saved, but also the flux of the liquid medicine is ensured.
Description
Technical field
This utility model relates to technical field of medicine packaging, particularly relates to a kind of single hard tube interface of anti-leakage of transfusion bag.
Background technology
The non-PVC hard tube of shape of all kinds connects the appearance of pouch-type the popularizing of Chinese Medicine market along with infusion solutions is non-PVC-soft-bag-packaged, for hard tube interface non-PVC-soft-bag, allows all very the problem----leakages of headache of each pharmaceutical factory.Just (leakage at its interface position will account for more than 90% of total leakage in mouth of pipe junction at the main position of non-PVC-soft-bag product generation leakage, the main reason of leakage is the reason that is subjected to bag design molding, reason one: the hard tube interface is from bigger as guaranteeing that the medicinal liquid flow mouth of pipe designs, and the draw ratio to the film material in welding process is bigger.Reason two: the film material of the attenuation that has been stretched is subjected to the extruding in mould and the joint weld process in welding process, thus cause joint weld handing-over partly the film material become extremely thin a little less than.Reason three: if the seam welding causes the potential quality risk of product not reach obturation effect more probably, so general pharmaceutical factory does not produce the risk of seepage for product, product interface position is all heavier for guaranteeing the tightness welding in process of production, after its welding is overweight, the film material is squeezed more serious, also corresponding increase of probability of leakage in the transportation of postorder, use.The appearance of comprehensive above reason, soft bag leakage problem is a technical barrier all the time.
The utility model content
The purpose of this utility model is to provide a kind of single hard tube interface of anti-leakage of transfusion bag.
This utility model is achieved by the following technical solution:
The single hard tube interface of a kind of anti-leakage of transfusion bag, this interface is made up of liquid feeding mouth and both wings solder side 3, and wherein liquid feeding mouth is made up of liquid feeding mouth top 1 and liquid feeding mouth bottom 2; Both wings solder side 3 is made up of clamping circle neck 5 and 6, interface both wings 7, the big fillet 8 of both wings, both wings roundlet angle 9, interface neck 12, joint weld end face 13, interface wing limit fillet 14; Joint weld end face 13 connecting interface necks 12, wherein interface neck 12 is provided with clamping circle neck 5,6, and clamping circle neck 5,6 connects application of anti-leakage layers 4, both wings big fillet 8 both wings roundlet angles 9 and interface wing limit fillet 14; Application of anti-leakage layers 4 is provided with application of anti-leakage layers convex surface 10 and application of anti-leakage layers convex surface 11; Interface both wings 7 connect to form with liquid feeding mouth top 1, liquid feeding mouth bottom 2.
Advantage of the present utility model be to have reduced because of weld size excessive in the film material welding process to the serious stretching problem of film material, thereby guaranteed the toughness of interface and film material handing-over position film material, effectively reduce the welding leakage rate at 90% interface position.Simultaneously not only saved cost but also guaranteed medicinal liquid flow.
