Description

A kind of soft-packing transfusion plug of easy-to-operate

Technical field

The embodiments of the present invention is related to a kind of infusion manufacturing industry production field packaging material technology, more specifically, The embodiments of the present invention is related to a kind of soft-packing transfusion plug of easy-to-operate.

Background technique

The transfusion cork of existing flexible packing products production is by polycarbonate pipe fitting, drain inner cavity, seal gasket and outer cover Composition, outer cover are generally aluminium-plastic combined cover or pull fold-type dome pipe fitting.In production process, by the movement of mechanical device, even It is connected in the hose of infusion bag, realizes the assembling with infusion bag.In use, operator needs first to scratch aluminium-plastic assembling Dome pipe fitting re-disinfection is covered or pulled, is finally inserted into transfusion cork and is infused using the infusion end syringe needle of infusion apparatus.It is existing Transfusion cork using open-type aluminium-plastic combined cover or pull fold-type dome pipe fitting.The equal operating difficulties when opening, increases operation The labor intensity of person.For example, aluminium-plastic combined cover is when using preceding first removal aluminium-plastic combined cover outer cover, it has not been convenient to, it is not laborsaving, increase The difficulty of operator.It pulls fold-type dome pipe fitting and is pulling fold-type dome pipe fitting using preceding first removal, it is equally not laborsaving, and in interface point Irregular breaking point is presented in place after pulling open, have certain residual pieces, has certain security risk to operator, and not Conducive to the insertion of infusion niidl, operation difficulty is caused further to increase.It is internal empty and after syringe needle is inserted into drain chamber Between become narrow, be unfavorable for the discharge of liquid, finally influence injection quality.

Utility model content

The utility model overcomes the deficiencies in the prior art, provides a kind of reality of the soft-packing transfusion plug of easy-to-operate Mode is applied, operating difficulties when existing transfusion cork is opened can solve with expectation, security performance is unreliable, operator's large labor intensity The problem of.

In order to solve the above technical problems, a kind of embodiment of the utility model uses following technical scheme:

A kind of soft-packing transfusion plug of easy-to-operate, including outer cover, seal gasket and pipe fitting, the inside of the outer cover Seal gasket is set, and the top of pipe fitting is set together with seal gasket, forms closed liquid guiding cavity；And the liquid guiding cavity exists It is less than or equal to the bore of seal gasket with the bore of seal gasket contact position；The outside of the outer cover also sets up unlatching dress It sets.

Further technical solution is: the lowest calibre of the liquid guiding cavity is no less than 5.8mm.

Further technical solution is: non-slip texture is arranged on the opening device.

Further technical solution is: infusion arrow is provided on the opening device.

Further technical solution is: the edges and corners of the outer cover are set as rounded corner.

Compared with prior art, the beneficial effects of the utility model first is that: the device is for assisting flexible packing products raw The transfusion cork design scheme of production, suitable for the single-chamber bag of various specifications packed in flexible pouchy of being infused greatly, the auxiliary of multi-chamber-bag product type Production, the production especially suitable for double-hose soft bag product.Transfusion cork provided by the utility model designs that this body structure is simple, behaviour Make that safe ready, at low cost, stability is high, after combination forming its sealing is tight, practical, can effectively control leakage.This Optimization of the utility model to transfusion cork more passes through existing infusion apparatus in the market, and without the infusion apparatus specially matched, use scope is wider, Reliability is higher, and bring economic effect is very big.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical It is novel, it is not used to limit the utility model.

Embodiment 1

As shown in Figure 1, a kind of soft-packing transfusion plug of easy-to-operate, including outer cover 1, seal gasket 2 and pipe fitting 4, Seal gasket 2 is arranged in the inside of the outer cover 1, and the top of pipe fitting 4 is arranged in together with seal gasket 2, forms closed lead Sap cavity 3；And the liquid guiding cavity 3 is in the bore for being less than or equal to seal gasket 2 with the bore of 2 contact position of seal gasket；It is described The outside of outer cover 1 also sets up opening device 5.The lowest calibre L of the more preferably described liquid guiding cavity 3 is no less than 5.8mm.The unlatching dress It sets and is provided with infusion arrow 6 on 5.The edges and corners of the outer cover 1 are set as rounded corner 11.The mode of rounded corner 11 not only limits The external form infused in figure should meet needed for production to greatest extent.Infusion arrow 6 should be included on transfusion cork tube wall Or other positions, the thinking of design is more flexible, as long as not damaging to transfusion cork.

Embodiment 2

As shown in Fig. 2, the present embodiment is to change in the structure basis of embodiment 1 to the shape and size of pipe fitting 4 Into corresponding change also occurs to size for the shape of liquid guiding cavity 3 formed therewith.Specifically, the pipe fitting 4 be from outer cover 1 Junction is integrally formed to the multistage cylinder that end is sequentially reduced by diameter, more preferably, is had at every section of cylinder link position Designed arc-shaped appearance.
