Abstract
The invention relates to a combined cap for infusion, and belongs to the field of medical equipment. The combined cap is characterized in that an inner cap is arranged, wherein the upper part of the inner cap is of a tubular structure; an inner cap protection cover sleeves the upper part of the inner cap; a lower tube opening of the inner cap protection cover is connected with the tubular structure part of the inner cap in a sealed manner through an inner cap protection cover tearing point; an outer cap sleeves the outer part of the inner cap; the lower end of the outer cap is clamped on the outer side of the lower end of the inner cap; an upper port of the outer cap is connected with an outer cap protection cover in a sealed manner through an outer cap protection cover breaking point. Through adoption of the combined cap, a puncture step during infusion can be omitted, so as to fundamentally solve the problem of puncture desquamation.
Description
Technical field
The present invention relates to medical instruments field, is a kind of transfusion combined cover 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 combined cover, when fundamentally solving transfusion, needing puncture and the puncture littering problem that causes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transfusion combined cover; be provided with inner cap; its spy is that inner cap top is tubular structure; inner cap top is set with inner cap protective cover; inner cap protective cover lower nozzle is torn through inner cap protective cover and is a little tightly connected with the tubular structure portion of inner cap; inner cap outer cover is equipped with enclosing cover, and the lower end of enclosing cover is fastened on the outside of inner cap lower end, and enclosing cover upper port is tightly connected through enclosing cover protective cover breakaway poing and enclosing cover protective cover.
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 lateral wall of enclosing cover protective cover is processed with enclosing cover and breaks handle of cutting off the hands.The mouth of pipe on inner cap protective cover top is through heat sealing.
The invention has the beneficial effects as follows, in composite cover, abandoned butyl rubber plug, the piercing step of infusion process can be omitted, fundamentally solve this problem of puncture exfoliation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1, structural representation of the present invention.
Fig. 2, inner cover structure schematic diagram of the present invention.
Fig. 3, outer cover structure schematic diagram of the present invention.
1. inner caps in figure; 2. enclosing cover; 4. exterior and interior cover fixing lug boss, 5. inner cap protective cover is torn a little, 6. inner cap protective cover; 7. inner cap heat seal sealing station; 8. with transfusion device adapter link position, 9. exterior and interior cover fixed groove, 11. enclosing cover protective cover breakaway poings; 12. enclosing covers break handle of cutting off the hands, 18. enclosing cover protective covers.
Detailed description of the invention
In Fig. 1, Fig. 2, Fig. 3; the present invention is provided with inner cap 1; inner cap 1 top is tubular structure; inner cap 1 top is set with inner cap protective cover 6; the mouth of pipe on inner cap protective cover 6 top is through heat sealing; the mouth of pipe on inner cap protective cover 6 top is inner cap heat seal sealing station 7, installs rear employing heat sealing sealed by inner cap 1 for medicine liquid irrigation, does not adopt the reason of direct sealing during injection moulding to be consider the convenience of the injection moulding demoulding.Inner cap protective cover 6 lower nozzle is torn through inner cap protective cover and a little 5 is tightly connected with the tubular structure portion of inner cap 1, and inner cap protective cover is torn and a little 5 is designed to thinner connection, so that can easily break disconnected when nurse uses.Inner cap 1 outer cover is equipped with enclosing cover 2, the lateral wall of inner cap 1 lower end is processed with the exterior and interior cover fixing lug boss 4 of annular, described exterior and interior cover fixing lug boss 4 is fastened togather with the annular exterior and interior cover fixed groove 9 on enclosing cover 2 lower end inside wall, the lower end of enclosing cover 2 is fastened on the outside of inner cap 1 lower end, enclosing cover 2 upper port is tightly connected through enclosing cover protective cover breakaway poing 11 and enclosing cover protective cover 18, the lateral wall of enclosing cover protective cover 18 is processed with enclosing cover and breaks handle 12 of cutting off the hands, moving enclosing cover breaks when cutting off the hands handle 12, enclosing cover protective cover 18 is broken disconnected from enclosing cover protective cover breakaway poing 11, enclosing cover protective cover breakaway poing 11 is thinner junction point so that break and disconnectedly expose inner cap 1, can infuse in upper end transfusion connector being inserted into inner cap 1.
