But, existing infusion connector all relative complex in structure and assembling, such as Chinese Patent Application No.: 201220321650.2 disclose one " has the non-PVC soft bag transfusion joint of break-off type enclosing cover ", and it comprises the PC union joint being provided with plug hole, the break-off type enclosing cover being installed in the plug in plug hole and being connected with PC union joint.The various piece of this Soft Bag Infusion Connector is all independent design, production, and then carries out combination assembling just obtained final products.Above-mentioned this split type infusion connector structure is too complicated, is unfavorable for the raising of production efficiency; Further, because plug and PC union joint are two independently parts, when plug being placed in moulding consent, there will be plug unavoidably and loosen, thus cause medicinal liquid leakage problem.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to provide a kind of simple type Soft Bag Infusion Connector, and it not only has reliable sealing property, and structure is simple, is convenient to manufacture and assembling, can reduce production cost, cut the waste, meet environmental requirement.
For achieving the above object, the present invention adopts following technical scheme:
A kind of simple type Soft Bag Infusion Connector, comprises integrated union joint and sealing-plug, and described union joint inside is provided with the liquid through-hole for liquid medicine flow, and this liquid through-hole is provided with medicinal liquid entrance and medicine liquid outlet; Being provided with the sealing thin-walled of this liquid through-hole of obstruct in described union joint near one end of medicine liquid outlet, forming one between this end of sealing thin-walled and union joint for holding the container cavity of described sealing-plug.
Further, described union joint is sticked near one end end face of medicine liquid outlet the sealing film of this union joint of capping; Sealing thin film can prevent extraneous dust from dropping on sealing-plug, can strengthen the sealing of this simple type Soft Bag Infusion Connector further.
Further, described union joint is provided with the connecting portion for being connected with transfusion flexible bag near the end of medicinal liquid entrance.
Further, described union joint and sealing-plug are equipped with two, and two union joint parallel interval are arranged, and the connecting portion of two union joints is connected.
Further, described in the connecting portion that is connected all be set to wedge shape along the two ends of the line of two union joints, this wedge-shaped design is conducive to connecting portion and is better connected with the bag mouth of transfusion flexible bag.
Further, described union joint adopts polypropylene material to obtain, and described sealing-plug adopts thermoplastic elastic material to obtain.
Compared to prior art, the beneficial effect that the present invention brings is:
By union joint is connected in integrated mode with sealing-plug, not only can guarantee the sealing of this simple type Soft Bag Infusion Connector, its structure can also be simplified, be convenient to manufacture and assembling, thus reach the object reducing production cost and cut the waste, meet environmental requirement.
Two of object of the present invention is to provide a kind of soft bag infusion system, comprises transfusion flexible bag and simple type Soft Bag Infusion Connector as described above, and this transfusion flexible bag and simple type Soft Bag Infusion Connector adopt heat to melt process seal to be connected.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the present invention is described further:
Refer to Fig. 1 to Fig. 3, it is the structural representation of a preferred embodiment of the present invention, and in the present embodiment, this soft bag infusion system comprises transfusion flexible bag 1 and simple type Soft Bag Infusion Connector 2.
The Soft Bag Infusion Connector of simple type described in the present embodiment 2 is dual terminal structure, namely two joints be arranged in parallel are comprised, each joint includes integrated union joint 21 and sealing-plug 22, described union joint 21 adopts polypropylene (Polypropylene) PP to obtain, and described sealing-plug 22 adopts thermoplastic elastomer (TPE) TPE (Thermoplastic Elastomer) to obtain.
Described union joint 21 inside is provided with the liquid through-hole 23 for liquid medicine flow, and this liquid through-hole 23 is provided with medicinal liquid entrance and medicine liquid outlet; Described sealing-plug 22 sealing is blocked in this medicine liquid outlet place; Being provided with the sealing thin-walled 24 of this liquid through-hole of obstruct in union joint 21 near one end of medicine liquid outlet, forming one between this end of sealing thin-walled 24 and union joint 21 for holding the container cavity (not indicating in figure) of described sealing-plug; The present invention is in order to ensure that PP union joint 21 and TPE sealing-plug 22 can better reach sealing effectiveness, adopt the double color mould technology of single injection-molded, PP union joint 21 and TPE sealing-plug 22 are completed injection moulding in one set of die, without the need to manually assembling again, and assemble reliable non-loosening, a large amount of production costs can be reduced.Each union joint 21 is equipped with the connecting portion 25 for being connected with transfusion flexible bag 1 in the end near medicinal liquid entrance, the connecting portion 25 of two union joints 21 is connected, the connecting portion 25 that this is connected all is set to wedge shape along the two ends of the line of two union joints 21, and this wedge-shaped design is conducive to connecting portion 25 and is better tightly connected with the bag mouth of transfusion flexible bag 1; Can realize being tightly connected after this connecting portion 25 and the bag mouth hot melt of transfusion flexible bag 1, described sealing thin-walled 24 can make TPE sealing-plug 22 cannot with drug contact, safe and reliable.
