Abstract

The utility model relates to a medical utensil, in particular to a diaphragm closed plastic transfusion bottle. The bottle mouth of the plastic transfusion bottle is provided with a rubber plug utilizing an outer cap, and an inner diaphragm is arranged between the rubber plug and the bottle mouth of the plastic transfusion bottle. The upper end of the outer cap is provided with an outer diaphragm. The upper end of the bottle mouth of the plastic transfusion bottle is provided with an upper ring which protrudes outwards, and the lower end of the outer cap is provided with a buckle which is contracted inwards and can fasten the upper ring. The edge of the rubber plugs respectively extends upwards and downwards, and the edges of the upper and lower surfaces of the rubber plug are respectively provided with upper and lower circular rings. The lower circular ring is buckled on the outer wall of the upper end of the bottle mouth of the plastic transfusion bottle and the upper ring. The upper end of the outer cap is provided with an inner ring which extends downwards after extending backwards, and the upper circular ring is embedded in a groove which is formed by the inner ring. While in use, the utility model can avoid the problems that water is leaked, filings are fallen, and the needle head is slid off, etc.

Description

Diaphragm Enclosed Type Plastic Infusion Bottle

Technical field

This utility model relates to a kind of medical apparatus, refers in particular to a kind of Diaphragm Enclosed Type Plastic Infusion Bottle.

Background technology

Existing plastic infusion bottle utilizes three-in-one plastics easy-open lid of being made up of inner cap, enclosing cover and plug or the aluminium plastic top-pop lid of being made up of plug, aluminium-plastic cap to seal usually.The common issue with that these two kinds of structures exist is: in use all can leak, phenomenons such as exfoliation and syringe needle landing, when serious even can cause infusion reaction.

Summary of the invention

The objective of the invention is to design a kind of Diaphragm Enclosed Type Plastic Infusion Bottle, occur leaking when avoiding using, problem such as exfoliation and syringe needle landing.

According to design provided by the utility model, on the plastic infusion bottle bottleneck, utilize enclosing cover to fasten plug, between plug and plastic infusion bottle bottleneck, interior diaphragm is arranged, in the upper end of enclosing cover outer membrane is arranged.

Interior diaphragm and plastic infusion bottle bottleneck are heated and are pressed into one.Outer membrane and enclosing cover are heated and are pressed into one.

The upper end of plastic infusion bottle bottleneck have outwards outstanding on ring, the latch closure of ring on can the fastening of inside contraction is set in the lower end of enclosing cover, the edge of plug makes progress and downward extension respectively, upper and lower faces edge at plug forms upper and lower annulus respectively, and following annulus be buckled in the plastic infusion bottle bottleneck the upper end outer wall and on encircle, upper end at enclosing cover is provided with the internal ring that extends internally the back, extends downwards, and last annulus embeds in the groove that is formed by internal ring.

Interior diaphragm and plastic bottle all adopt polypropylene plastics to be made.The plastic infusion bottle bottleneck is positioned at the upper end of a complete plastic infusion bottle.

The utility model has the advantages that: because outside plastic infusion bottle bottleneck and plug reach, covered pressing interior diaphragm and outer membrane, only need during use outer membrane is torn off, syringe needle is inserted through plug, can enter in the transfusion flexible bag after passing interior diaphragm again, in this process, issuable chip can not fall into plastic infusion bottle because of the stopping of interior diaphragm on the plug, thus the safety when having improved transfusion.Simultaneously, because the iris action of outer membrane makes plug be sealed in the inside, avoided external pollution.

Description of drawings

Fig. 1 is a sketch map of the present utility model.

The specific embodiment

As shown in the figure: on plastic infusion bottle bottleneck 5, utilize enclosing cover 2 to fasten plug 3, at

plug

3 and 5 of plastic infusion bottle bottlenecks interior diaphragm 4 is arranged, when syringe needle is inserted through plug 3 and enters in the plastic infusion bottle, interior diaphragm 4 can stop effectively that the chip on the plug falls in the transfusion bag, in the upper end of enclosing cover 2 outer membrane 1 is arranged, plug 3 is closed in the enclosing cover 2, in order to avoid contaminated.

Interior diaphragm 4 and plastic infusion bottle bottleneck 5 and outer membrane 1 and enclosing cover 2 can be pressed into one respectively, and interior diaphragm 4 and plastic infusion bottle bottleneck 5 can adopt the plastic production that meets hygienic requirements to form, to guarantee the safe and reliable of plastic container for infusion.

Have in the upper end of plastic infusion bottle bottleneck 5 and to encircle 9 on outwards outstanding, the latch closure 8 of ring 9 on can the fastening of inside contraction is set in the lower end of enclosing cover 2, the edge of plug 3 makes progress and downward extension respectively, form upper and lower annulus 10 respectively at the upper and lower faces edge of plug 3, and following annulus 10 is buckled in the upper end outer wall of plastic infusion bottle bottleneck 5 and goes up on the ring 9, upper end at enclosing cover 2 is provided with the internal ring 11 that extends internally the back, extends downwards, and last annulus 10 embeds in the groove that is formed by internal ring 11.During installation, earlier interior diaphragm 4 is pressed together on the plastic infusion bottle bottleneck 5, again plug 3 is placed on the upper end of plastic infusion bottle bottleneck 5, and the inwall of the following annulus 10 on the plug 3 and the upper end outer wall of plastic infusion bottle bottleneck 5 are adjacent to, the lower surface of following annulus 10 rests on the upper surface of ring 9, again the internal ring on the enclosing cover 2 11 is buckled on the last annulus 10 of plug 2, reuse power with enclosing cover 2 to pressing down, what make that latch closure 8 on the enclosing cover 2 fastens plastic infusion bottle bottleneck 5 upper ends goes up ring 9, last annulus 10 embeds in the groove that is formed by last ring 11, plug 3 is closely withheld with plastic infusion bottle bottleneck 5 be in the same place.

The lower end of plastic infusion bottle bottleneck 5 forms a complete plastic infusion bottle 12, only need tear outer membrane 1 during use, syringe needle is inserted and is penetrated plug 3 and interior diaphragm 4 gets final product.
