Abstract
The invention discloses a sealing cover used for a large transfusion plastic bottle and a plastic bag, which consists of an inner cover body and an outer cover body. The inner cover body is used for sealing a bottle mouth or an aperture tube on the bag, and is provided with a quick coupler; the quick coupler is provided with a thinned wall structure used for puncturing; a puncture outfit is provided with a structure matched with the puncture quick coupler arranged on the inner cover body; a transfusion puncture outfit is inserted into the thinned wall structure on the quick coupler and completes coupling connection to form a transfusion path, thereby discarding a rubber plug, and avoiding liquid medicine pollution generated by scarp off of the plug; moreover, the process is also simplified during manufacturing large transfusion so as to reduce cost. The proposal especially designs the puncture outfit against the invention with simple structure, thereby achieving the aim of realizing transfusion path.
Description
Technical field
The present invention relates to medical apparatus and instruments, be specially large plastic bottle for transfusion, plastic bag with seal cover and supporting bottle plug puncture unit.
Background technology
At present, in medical large transfusion plastic bottle, plastic bag field, infusion bottle commonly used, bag are the combination of outer cover, plug and interior lid with the seal cover structure, fix by the mode of extruding by buckling groove and fastening platform between outer cover and the interior lid, thereby plug is arranged on the effect of playing sealing between the two.When the corpsman,hospital uses, draw back easily tore film or pull-tab or neck easy to break earlier plug is exposed, again the plug perforator on the transfusion device is passed plug and interior lid enters in infusion bottle, the transfusion bag, plug is easy to generate the plug desquamation during puncture.And plug need to add many compositions in manufacture process, and there is certain potential safety hazard in human body, and also just for fear of the pollution of plug to medicinal liquid, the inner cap in the common combinations lid plays the effect that plug and medicinal liquid directly contact that intercepts.In the infusion process, the easiest plug desquamation that causes of angle puncture draw point.Side mouth puncture draw point and the less generation plug desquamation of plastics perforator meeting, but the processing technique of side mouth puncture draw point is comparatively complicated, and plastics perforator resistance when puncture plug and inner cap is bigger.And any puncture all might produce the plug desquamation and pollute medicinal liquid.
Summary of the invention

The described interior lid of lid ready-packaged joint is provided with two or more ready-packaged joints in described.
Described outer cover is pull-tab or neck easy to break, also can be the easily tore film structure, and outer cover plays the aseptic condition that buffer action keeps puncture orifice, during use, draws back pull-tab, easily tore film or folding and tears neck easy to break and just can carry out puncture procedure.
Described outer cover and interior lid are polypropylene or polyethylene injection mo(u)lding, and wherein easily tore film is that PET and polypropylene or polyethylene are composited.
The matching used bottle plug puncture unit of described seal cover, have transfusion path or the air inlet and the transfusion dual pathways in the perforator, it is characterized in that: perforator have with interior lid on the structure that matches of puncture ready-packaged joint, when the thin-wall construction of perforator head puncture ready-packaged joint and finish joint and connect the back and form the path of infusing.
Described perforator body is provided with sealing ring, when the thin-wall construction of perforator head puncture ready-packaged joint and after finishing joint and connecting, can seal up the puncture ready-packaged joint.
Connection between described perforator and the ready-packaged joint can be adopted direct inserted mode or thread connecting mode, is threaded to comprise that the female thread connection is connected with external screw thread.
Described perforator body is provided with slot, and when perforator adopts direct inserted mode, slot can match with quick union.
Described seal ring material is to have the material that 30 to 70 Xiao press hardness, and for example silicone polymer is made.
Compared to existing technology, advantage of the present invention is as follows:
1, seal cover of the present invention is made up of interior lid and outer cover, has abandoned these parts of plug.
2, this programme has been avoided the liquid medicine contamination because of the generation of plug desquamation fully, and also simplifies process in the infusion solutions production process, reduces cost.
3, this programme specialized designs at the employed perforator of structure of the present invention, simple in structure, reach the purpose that realizes the transfusion path.
