Description
Technical field
The present invention relates to a kind of therapeutic medical fluid delivery apparatus, relate in particular to the two plug of a kind of medical double-head pad pasting transfusion cork.
Background technology
Along with the generally application of infusion treatment, infusion model has passed through from open, semi open model to fully closed evolution, and transfusion device changes the soft bag of non-PVC composite membrane of today into by the vial started thereupon.For realizing dosing and transfusion, generally be provided with transfusion cork and medicine plug in soft bag.In prior art, mainly contain two schemes, a kind of is that transfusion cork and medicine plug are independent, adopts two rubber stoppers, and its production cost is larger; Another kind of transfusion and dosing share a rubber stopper, but easily pollute.Install in addition, change dressings and the operating process requirement transfusion cork such as dosing has convenience, agility, practicality, the security consideration for patient in infusion process requires transfusion cork to have sealing.The huge market demand and the mass of production require again transfusion cork to have low cost.The two plug of the double end pad pasting transfusion corks of therefore need a kind of good seal performance, exempt to pollute, cost is low, convenient and practical.
Summary of the invention
The objective of the invention is the deficiency for prior art, a kind of two plug of double end pad pasting transfusion corks that can solve the shortcoming of above-mentioned prior art existence are provided.
In order to realize purpose of the present invention, the present invention adopts following technical scheme: the two plug of a kind of medical double-head pad pasting transfusion cork, comprise lid, transfusion a plug, medicine dosing port plug and composite film-stuck, wherein, described lid has a separate transfusion plug chamber and medicine dosing port plug chamber; A described transfusion plug is fixed in a transfusion plug chamber, and the lower surface of a transfusion plug contacts location with a transfusion bottom surface, plug chamber, and a transfusion plug upper surface is located by fixture; Described medicine dosing port plug is fixed in medicine dosing port plug chamber, and the lower surface of medicine dosing port plug contacts location with bottom surface, medicine dosing port plug chamber, and upper surface is located by fixture; Composite film-stuck is processed upper surface and the lateral surface that is covered in lid through sealing.
Further, the diameter of a described transfusion plug chamber is greater than the diameter of described medicine dosing port plug chamber.
Further, being shaped as of a described transfusion plug is cylindrical in fact, and diameter, height are identical with a plug chamber of infusing, and upper and lower two ends are provided with pit, and end face forms annular.
Further, being shaped as of described medicine dosing port plug is cylindrical in fact, diameter, highly identical with medicine dosing port plug chamber, and upper and lower two ends are provided with pit, and end face forms annular.
Further, described fixture is the bent buckling on lid, and bent buckling bending at a certain temperature distortion, be adjacent to the plug upper surface to reach the purpose of axial restraint plug.
Preferably, described composite film-stuck and plug upper surface, lid side surface are processed by the composite membrane welded seal.
Advantage of the present invention: transfusion room and add coyote hole separately, avoid polluting; The plug processed, reduce volume, cost-saving; The composite film-stuck encapsulation process, guarantee safety; During use, as long as lid is connected by fusion or adhesive seal with transfusion flexible bag, tear composite film-stuck off, easy to operate.
