Abstract
The invention belongs to the field of medical instruments, and relates to an infusion bag connection device. The infusion bag connection device is provided with an inner cover, and is characterized in that the upper part of the inner cover adopts a tubular structure, the outside of the inner cover is sleeved by an outer cover, the lower end of the outer cover is clamped on the outer side of the lower end of the inner cover, the inner cover is sleeved by a tubular infusion connector, a ring-shaped upper boss and a ring-shaped lower boss are formed in the outer side wall of the infusion connector, and the infusion connector between the upper boss and the lower boss is sleeved by a connector fixing clamp ring. The infusion bag connection device provided by the invention fundamentally solves the problem of puncture falling chips caused by a puncture during infusion; meanwhile, the adopted connection method effectively solves the problem that an infusion device is easily detached from an infusion bottle during movements of a patient.
Description
Technical field
The present invention relates to medical instruments field, is a kind of transfusion bag connecting device in detail.
Background technology
As everyone knows, with the development of medical packaging technology, infusion solutions just progressively develops into present plastic bottle or packed in flexible pouchy from original glass bottle packaging, so that transport and pollution when reducing transfusion.The bottle cap packaging of infusion solutions also wraps up the form that plug develops into plastic outer cover and inner cap parcel plug, to adapt to the welding needs of plastic infusion packaging by plastic-aluminum.
At present, infusion solutions composite cover generally adopts enclosing cover, plug, inner cap three incorporating aspects to form.Plug plays sealing and ensures lancet puncture no leakage and pin puncture needle effect.Inside build fixing glue plug, close the effect of medicinal liquid.Build the effect of protecting glue plug and inner cap outward.Composite cover and infusion solutions interface adopt heat seal to weld.After requiring that in actual application enclosing cover is torn, puncture needle is through plug and inner cap, and no leakage, pins puncture needle, requires that puncture exfoliation is as far as possible few simultaneously.
Current plug used is halogenated butyl rubber substantially, and inner cap generally adopts COPP or modified polypropylene material.Because halogenated butyl rubber plug formula is comparatively complicated, ensure to have certain elasticity and sealing, require that puncture force can not be too high simultaneously, cause halogenated butyl rubber plug quality to be comparatively difficult to ensure card, especially puncture exfoliation poor performance.Simultaneously inner cap also has the puncture exfoliation of part when puncturing, and the exfoliation sum that causes puncturing in medicinal liquid is higher.Puncture exfoliation enters medicinal liquid, and follow medicinal liquid and enter blood of human body together, transfusion particle is the main cause causing clinical transfusion react, also can cause that blood vessel embolism, phlebitis, lung meat swell simultaneously, thrombocytopenia, anaphylaxis.
Current puncture needle used is divided into draw point, moulds pin, three kinds, steel plastic compount pin.Puncture of steel needles power is lower, but easily comes off, and easily drops during patient activity when infusing.Mould pin to be not easy to drop, but during puncture, puncture force is higher, and easily produces exfoliation.Although steel plastic compount pin can balance the littering problem that drops and puncture, still fundamentally do not solve puncture littering problem.And draw point is owing to will have cutting, bruting process, and production process can not complete in cleaning shop, be difficult to ensure its product quality.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of transfusion bag connecting device, need puncture and the puncture littering problem that causes when fundamentally solving transfusion, and when the connected mode adopted efficiently solves patient activity transfusion device easily and infusion bottle to come off problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transfusion bag connecting device, be provided with inner cap, its spy is that inner cap top is tubular structure, inner cap outer cover is equipped with enclosing cover, the lower end of enclosing cover is fastened on the outside of inner cap lower end, cover in tubulose transfusion connector is sleeved on, transfusion connector lateral wall is provided with convex platform and the lower convex platform of annular, and adapter is fixed on the transfusion connector that snap ring is sleeved between convex platform and lower convex platform.
The present invention also realizes by following measure: the exterior and interior cover fixing lug boss lateral wall of inner cap lower end being processed with annular, and the annular exterior and interior cover fixed groove on described exterior and interior cover fixing lug boss and enclosing cover lower end inside wall is fastened togather.The medial wall that snap ring lower end fixed by adapter is processed with adapter and the enclosing cover fixed groove of annular, the shaped outer cover on described adapter and enclosing cover fixed groove and lateral wall, enclosing cover upper end and adapter fixing lug boss are fastened togather.The mouth pipe external diameter of the transfusion device adapter link position of inner cap upper end has 3-5 degree slope angle from top to bottom.
The invention has the beneficial effects as follows, in composite cover, abandoned butyl rubber plug, and eliminate piercing process, fundamentally solve puncture exfoliation this problem, and when the connected mode adopted efficiently solves patient activity transfusion device easily and infusion bottle to come off problem.
