Abstract
The utility model relates to a medical bottle stopper for medical container articles. The middle of the outer surface of the bottle stopper is provided with an annular groove and a circular arc face, and the outer surface of the bottle stopper is in the shape of the T; the inner surface is covered with a layer of macromolecule polymer film. The bottle stopper with the structure has good isolation property and can obstruct components of rubber goods which are harmful to the human body and have influence for the medicine. The utility model has the advantages of heat resistant, corrosion resistant, good chemical stability, good sealing property, simple washing, less outside pollution, and high qualification rate for the medicine, and the utility model does not generate the reaction with various medicines, can remain the valence of the medicine, and can prolong the storage life of the medicine. The bottle stopper can be widely used for the sealing of various bottle jacks such as the medical service transfusion, the powder injection, the fluid acupuncture, oral administration medicines, etc.
Description
The utility model relates to a kind of medical container articles for use, pharmaceutical bottle stopper.
Bottle stopper with various natural rubbers and neoprene are made reaches and some drugs generation reaction owing to the vulcanizator in its component, accelerator, additive, filler etc. are harmful, so can't directly use.China all adopts pad one deck mylar as the method that intercepts on medicine is produced at present, but film and bottle stopper inner chamber are not close to, once the brisement of syringe needle puncture rear film, particulate in the rubber and film fragments are infiltrated medicine input human body, cause iatrogenic disease.The film pad is in the peripheral fold that produces of bottle stopper in addition, and leak tightness is poor, and as infusion solutions turned welt bottle stopper, above-mentioned shortcoming is more serious.Influential to drug quality.
The patent No. 88210363 " infusion bottle external hollow plug ", though shape improve, outer protruding in recessed, also be unable to do without traditional turned welt shape and on plug, paste mylar.
The purpose of this utility model is to provide a kind of pharmaceutical bottle stopper, and good barrier, leak tightness are arranged, and does not produce chemistry or biological respinse with various medicines, thus keep medicine tire the storage period of prolong drug.
The utility model is achieved in that pharmaceutical bottle stopper makes the bottle stopper that is shaped as T shape with pharmaceutical rubber, and annular recess or arc surface are arranged in the middle of the bottle stopper outside face, and inside face covers one deck medical grade high molecular polymer film.
Fig. 1, structural representation of the present utility model:
Bottle stopper (1), film (2).
Fig. 2, the utility model alternative plan structural representation:
Bottle stopper (1) '.
Fig. 3, the utility model third party case structural representation:
Bottle stopper (1) ".
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
With reference to Fig. 1,2,3, this bottle stopper (1), (1) ', (1) " be shaped as the T type, annular recess or arc surface arranged in the middle of the T type outside face; pin holes is descended; be convenient to the use of disposable transfusion device, can have the outer aluminium lid of tegillum to be used with the centre in addition, alleviate operator's labour intensity.The inside face of inner chamber is that circular arc does not have the dead angle, so that film is close to, and is convenient to washing.The no inner chamber that also can make as shown in Figure 3 is flat shape, is suitable for the blood plasma blood product and uses.
The neck of inwall is formed the R angle, and make the R angle bigger, in 1.5～2mm scope, the sealing when being beneficial to the glass bottle internal orifice sharp edge being arranged can not scratched bottle stopper.
Be laminated with one deck medical grade high molecular polymer film making on the natural or elastomeric inside face of bottle stopper, and make itself and bottle closure of rubber one-shot forming.This high molecular polymer membraneous material is selected according to different range of uses.Available poly-fluorine class films such as costly medicine such as anticancer, antibiotic, various amino acidses, polytetrafluoroethylene or perfluoroethylene-propylene, general medicine such as salt solution, compound sodium chloride can be used modified polypropene, the also available silastic film of other class, decision as required.
This bottle stopper has good barrier, can actv. intercepts vulcanizator, accelerator, aging inhibitor, additive, filler residue in the rubber component, enters medicine, thereby prevented to the harm of human body with to the influence of tiring of medicine.
Good heat-resisting, withstanding corrosion, acid and alkali-resistance, grease are arranged, ageing resistance is good, chemical inertness is good, film and various medicine do not produce chemistry or biological respinse, thereby keep tiring of medicine.
Good sealing property is arranged,, between rubber and glass bottle opening, played the effect of one deck packing seal, so can prolong the storage period of medicine because the permeability to air of film own is poor.
Carrying out washing treatment is simpler than other Medical bottle stopper, outside contamination is lacked, can improve the qualification rate of pharmaceutical preparation.
Can form automated production.
This bottle stopper can be widely used in the sealing of various medical transfusions, powder pin, liquid drugs injection, oral drugs bottleneck, and the sealing that is specially adapted to antibiotic and valuable drug is used.
Claims (3)
1, the pharmaceutical bottle stopper of a kind of medical container articles for use is shaped as the T type, it is characterized in that being covered with one deck medical grade high molecular polymer film at bottle stopper T type inside face.
2, bottle stopper according to claim 1 is characterized in that the high molecular polymer membraneous material is polytetrafluoroethylene or perfluoroethylene-propylene or modified polypropene or silastic.
3, bottle stopper according to claim 1 is characterized in that annular groove or arc surface being arranged in the middle of the T type bottle stopper outside face, and R is in 1.5～2mm scope, and inner chamber becomes arc surface, or does not have inner chamber and be flat shape.
