Abstract
The utility model discloses a new structure of mould cape seal and charging interface and a new structure especially suitable for magnetic discharge welding. Step structure is adopted on the joint surfaces of the magnetic discharge welding. Platinum analog washers are on the surface of the step outer rings. Platinum analog washers are as conductors and the magnetic discharge welding can produce electromagnetism eddy on the platinum analog. On the joint surface of the two binders produces an extremely thin melted layer with 2-3s. The two binders can seal and joint firmly with a little pressure. The convex can obstruct the thermal radiation so that the drugs in the intracavity of drug joint can be protected from thermal influence to ensure the drug safety.
Description
Technical field
This utility model belongs in the pharmaceuticals industry infusion preparation, a kind of architecture advances that medicine filling mouthpiece that a kind of and soft bag is conjuncted and composite cover are tightly connected.
Background technology
Existing transfusion bag all adopts pharmaceutical transparent plastic to make.After the inner chamber of medicine filling mouthpiece loaded desired medicine, top sealed with composite cover, and bottom and powder charge (water preparation) and sterile-processed soft bag are conjuncted, had just become the transfusion bag of band medicine filling mouthpiece.The method of medicine filling mouthpiece and composite cover sealing becomes key technology, following method is mostly adopted in sealing between them, a kind of method is between medicine filling mouthpiece and composite cover, upper and lower heating plate with metal carries out high temperature heating (600-700 ℃) earlier, after treating both roasting melting of faying face, upper and lower heating plate withdraws from fast; The pressure head that is in then directly over the composite cover is descending, and composite cover is pressed to medicine filling mouthpiece fast, and both roasting molten faying faces are close to and in conjunction with being hot weld, thereby reach the purpose of sealing.The advantage of this method is that sealing is reliable, its weak point is that the high temperature in the process of sealing has a negative impact to the medicine in the medicine filling mouthpiece inner chamber, may cause medication dangerous, antibiotic medicine particularly, it is in storing, production, and in the process of use, general temperature should be controlled below 60 ℃, obvious this method for sealing, inapplicable to said medicine.Limited extensively promoting the use of of it; Next seals process such as misoperation, and may causing two, to be heated face on fire.Also has a kind of method, upper end at medicine filling mouthpiece is provided with connecting ring, and the pressing boss is arranged on the connecting ring face of cylinder, and the inner ring surface of pressing boss and composite cover is tightly connected through pressing, its advantage is not heat in the process of sealing, applicable surface enlarges, and technology is simple, and not enough place is that sealing is little reliable, having medicinal liquid in the use oozes out, both wasted, the possibility medication is dangerous again, and it is rare to use.
Summary of the invention
This utility model is for solving above-mentioned technical deficiency, the structure of particularly suitable magnetic discharge welding between a kind of medicine filling mouthpiece and the composite cover is provided, can intercept heat and propagate to the medicine filling mouthpiece inner chamber, the adverse effect of avoiding high temperature that medicine filling mouthpiece inner chamber Chinese medicine is produced guarantees drug safety.
The technical scheme in the invention for solving the above technical problem is: be provided with step on the faying face of medicine filling mouthpiece and composite cover, the metal platinum pad is arranged on the outer ring surface of step.
The beneficial effects of the utility model are: in the electromagnetism welding, composite cover and medicine filling mouthpiece are tightly connected reliably, and the medicine in the medicine filling mouthpiece inner chamber is not subjected to the influence of thermal radiation, drug safety, and subject range enlarges.

Among the figure: 1, composite cover; 2, medicine filling mouthpiece; 3, inner chamber; 4, step; 5, metal platinum packing ring
Specific embodiments
The electromagnetism welding is a kind of new technique welding that immediate development is got up, and is applied to the connection between the parts in addition more than two kinds in the plastics part in a lot of fields, and the quality of welding is good, and speed is fast.The inner chamber (3) of medicine filling mouthpiece (2) fills medicine and uses composite cover (1) to be tightly connected later on, thermofussion welding is a kind of method that is tightly connected of first-selection naturally, and many medicines have extremely strict restriction to temperature, should firm welding damage medicine quality in the medicine filling mouthpiece again and have just become wanting of people's researches of technique.This utility model (existing medicine filling mouthpiece and composite cover joint portion both sides have the bigger connecting ring of area) on the faying face of medicine filling mouthpiece (2) and composite cover (1) is provided with step (4), there is being metal platinum packing ring (5) (to have advantage on the extension property of aluminum and the price on the outer annular surface of step (4), the general aluminum platinum that adopts), this structure both had been suitable for the electromagnetism welding requirements, had good effect of heat insulation again.Composite cover (1), metal platinum (5) medicine filling mouthpiece (2) are pressed connection request before the welding, be seated, electromagnetism produces a kind of electromagnetic eddy rapidly through conductor metal platinum (5), 2-3 is in second, material between the faying face is under the effect of magnetic discharge welding heat effect, one deck film as thin as a wafer is melted, and omits plus-pressure between two conjunctions and just links together securely.Though magnetic discharge welding still belongs to the scope of thermofussion welding, but the operation principle of magnetic discharge welding is extremely similar to the high-frequency quenching principle of metal, the material that is heated to fusing point only is the extremely shallow epidermises of two connectors, the poor thermal conductivity of plastics own, fusing face is at both outer ring surfaces, and the time compole that is heated is short, and its temperature is intercepted by boss again, the temperature of medicine filling mouthpiece (2) inner chamber (3) is in room temperature substantially, and medicine wherein can not be subjected to pyritous influence.The metal platinum pad does not take out in the welding.Step surface can be by being provided with as shown in Figure 1; Also can on the joint face of medicine filling mouthpiece (2) boss be set on the inner ring surface, the structure of composite cover correspondingly cooperates, and the metal platinized platinum all is placed in the outer ring surface, and effect is identical.If adopt fixing structure between composite cover and interface, it is a kind of variation of boss structure, and principle is identical with effect.
Claims (2)
1, a kind of medicine filling mouthpiece and composite cover electromagnetism Welding Structure comprise composite cover (1), medicine filling mouthpiece (2), and it is characterized in that has step (4) on the faying face of medicine filling mouthpiece (2) and composite cover (1), and metal platinum packing ring (5) is arranged in its outer ring surface.
2, medicine filling mouthpiece according to claim 1 and composite cover electromagnetism Welding Structure is characterized in that metal platinum packing ring (5) is an aluminum platinum packing ring.
