The production technology of this transfusion bag accessory is first injection mo(u)lding agent structure, with easily tore film and tube for transfusion welding ring heat seal welding, has increased welding sequence one, complex process again; Especially owing to be provided with seal dissepiment in the tube for transfusion, when the packing film is decoded in plastic infusion acupuncture, easily fall bits, have potential safety hazard; The seal dissepiment that is punctured can be attached to the tube for transfusion inwall around the plastic infusion pin can't be contacted fully with the tube for transfusion inwall and have the risk of leakage.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of and solves that the difficulty that existing seal cover extensively exists is opened, the puncture exfoliation is many in clinical use, easy-to-leak liquid, easily the infusion vessel of defective such as sliding pin is with valve formula list standpipe seal cover.
For achieving the above object, this utility model infusion vessel single standpipe seal cover of valve formula, it is characterized in that, the single standpipe seal cover of this valve formula comprises that be used to the lid that is installed on the liquid filled container, the end face of lid is provided with the tube for transfusion that is communicated with the lid inner chamber, and the external port sealing of tube for transfusion is provided with open valve, lid, tube for transfusion and open valve are connected to an overall structure, wherein, described tube for transfusion is hollow circular cylinder, and the internal diameter of tube for transfusion is less than the external diameter of standard plastic transfusion needle.
Further, the lower surface of described open valve is that attenuate connects with parallel linking to each other of described tube for transfusion upper end, both connecting portions.
Further, the sidewall lower limb of described lid circumferentially is outward extended with the lid welding ring along it, and this lid welding ring is used for being tightly connected with described liquid filled container.
Further, the length of described tube for transfusion is less than the length of standard plastic transfusion needle.
Further, the internal diameter of described tube for transfusion upper end is less than the internal diameter of lower end, and the inner orifice of described tube for transfusion forms the taper hole structure.
Further, described tube for transfusion is made by elastoplast, and this elastoplast comprises the blend of polypropylene, polyethylene, polypropylene and thermoplastic elastomer (TPE).
Further, described open valve is the lamellar plate of flat structure.
Further, the wall thickness of described attenuate connecting portion is less than described tube for transfusion wall thickness.
Further, thickness from the pipe thickness of described tube for transfusion to described attenuate connecting portion is the gradual transition structure, and this gradual transition structure is from described tube for transfusion outer wall to inwall, from described tube for transfusion inwall to outer wall and the gradual transition structure from the inside and outside wall of described tube for transfusion to the centre.
This utility model had both been opened convenience, laborsaving, thoroughly stopped the potential safety hazard that the pad exfoliation brings because not containing gasket design again, simultaneously, the power of holding of plastic infusion pin is far longer than the resilience force of common composite cover Intermediate gasket, phenomenons such as sliding pin, leakage can not appear during transfusion, this utility model production cost is low, is a kind of economical safety product.
