The hard double nip of band crosspointer that adopts said structure when mixing medicine, main exist following not enough: one, during the sealing-plug of the needle point of dosing crosspointer on puncture medicament reservoir or infusion vessel,, be prone to make needle point to fracture in case firmly squint; Two, the needle point because of the dosing crosspointer is provided with a dosing hole, and when the puncture seal plug, in a single day the exfoliation on the sealing-plug stops up the dosing hole, and will cause mixing medicine can't carry out.
The utility model content
To the above-mentioned deficiency that exists in the prior art, this utility model provides a kind of not frangible, effectively avoids the hard double nip of the band diplopore crosspointer of mixed medicine channel jam.
In order to solve the problems of the technologies described above, this utility model has adopted following technical scheme:
Be with the hard double nip of diplopore crosspointer, comprise pedestal, mixed medicine interface, transfusion interface, mix medicine card body and dosing crosspointer, said dosing crosspointer is arranged on and mixes in the medicine card body, has two dosing holes that communicate with the interior passage of dosing crosspointer on the needle point of said dosing crosspointer.
Further, two dosing holes on the said needle point the dosing crosspointer axially on shift to install.
Further, have two inclined-planes on the needle point of said dosing crosspointer, a dosing hole is set on each inclined-plane.
Further, two inclined-planes are positioned at the relative both sides of needle point axis.
Further, the axis of two relative dosing crosspointers in inclined-plane on the said needle point is symmetrically distributed.
Further, two inclined-planes on the said needle point the dosing crosspointer axially on shift to install.
Further, on the inwall that mixes medicine card body, being symmetrically arranged with at least two is barb-like and is used to prevent the anti-slide fastener that medicament reservoir is loosening.
Further, the bottom of said mixed medicine card body is provided with annular rubber cushion, and a needle point of said dosing crosspointer passes annular rubber cushion and is stuck on the annular rubber cushion.
Further, be provided with in the said mixed medicine interface one be used to seal the mixed medicine passage in this mixed medicine interface barrier film, a needle point of dosing crosspointer is corresponding with barrier film.
The beneficial effect of this utility model is: this utility model on the needle point of dosing crosspointer, be provided with two with the dosing crosspointer in the dosing hole that communicates of passage; Two dosing holes are located on the different inclined-planes; Not only increase the intensity of this needle point, and two dosing holes on each needle point the dosing crosspointer axially on shift to install, during sealing-plug on puncture medicament reservoir or infusion vessel; Can effectively avoid the exfoliation on the sealing-plug to stop up this two dosing holes simultaneously, guarantee to mix medicine and carry out smoothly.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done to describe in further detail.
Like Fig. 1, shown in Figure 2; The hard double nip of band diplopore crosspointer; Comprise pedestal 1, mixed medicine interface 2, transfusion interface 3, mix medicine card body 4 and dosing crosspointer 5, dosing crosspointer 5 is arranged on and mixes in the medicine card body 4, and the needle point of dosing crosspointer 5 has two inclined-planes 6; Two inclined-planes 6 are positioned at the relative both sides of needle point axis and the axis symmetrical distribution of dosing crosspointer 5 relatively, and each inclined-plane 6 is provided with the dosing hole 8 that communicates with dosing crosspointer 5 interior passages 7.Two dosing holes 8 on the needle point dosing crosspointer 5 axially on shift to install.During sealing-plug on puncture medicament reservoir or infusion vessel; Two dosing holes 8 on the needle point one in front and one in back; Can effectively avoid the exfoliation on the sealing-plug to stop up this two dosing holes 8 simultaneously; Guarantee to mix medicine and carry out smoothly, also strengthened the intensity of needle point simultaneously, make dosing crosspointer 5 in piercing process, be difficult for being fractureed.
On the inwall that mixes medicine card body 4, being symmetrically arranged with at least two is barb-like and is used to prevent the anti-slide fastener 9 that medicament reservoir is loosening.In the present embodiment, on the inwall that mixes medicine card body 4, be symmetrically arranged with six anti-slide fasteners 9.Medicament reservoir snap in mix in the medicine card body 4 after, medicament reservoir can effectively avoid medicament reservoir in mixed medicine card body 4, to withdraw from or become flexible to opposite direction under the inhibition of anti-slide fastener 9.The port of mixing medicine card body 4 is provided with diaphragm seal 12, and diaphragm seal 12 makes to mix in the medicine card body 4 and is in sealing state, during use, removes diaphragm seal 12 and gets final product.
In pedestal 1 seam on infusion vessel; Implement to mix before the medicine; Mixed medicine passage in these barrier film 11 mixed medicine interfaces 2 capable of blocking makes the transfusion solvent in the infusion vessel keep sealing and not contacting with dosing crosspointer 5, and the solvent of avoiding infusing pours into through dosing crosspointer 5 and mixes in the medicine card body 4; Thereby the generation leakage, not only strict assurance in the infusion vessel transfusion solvent volume but also avoided using before pollution; Behind dosing crosspointer 5 puncture barrier films 11; Mixing medicine interface 2 is communicated with dosing crosspointer 5; Thereby make the transfusion solvent can flow into medicament reservoir and realize mixing medicine; And this moment, annular rubber cushion 10 promptly substituted barrier film 11, not only can intercept the transfusion solvent and contact with extraneous, had also limited transfusion solution and only can flow into medicament reservoir through dosing crosspointer 5.So strict control the has been set opening sequence of mixed medicine passage of this barrier film 11 has guaranteed the safety and sanitation of mixed medicine process.In addition, this barrier film 11 can be one-body molded with mixed medicine interface 2, and technology is simple, be prone to realize, and the cost of material is low, can not increase extra-pay.
Structure for needle point also can adopt structure as shown in Figure 3; Fig. 3 is the partial structurtes sketch map of dosing crosspointer embodiment two; Compare with the partial structurtes sketch map of dosing crosspointer embodiment one shown in Figure 2, its difference is: two inclined-planes 6 among Fig. 3 on the needle point dosing crosspointer 5 axially on shift to install.Equally; During sealing-plug on puncture medicament reservoir or infusion vessel, two dosing holes 8 on the needle point one in front and one in back can effectively avoid the exfoliation on the sealing-plug to stop up this two dosing holes 8 simultaneously; Guaranteeing to mix medicine carries out smoothly; Simultaneously two dosing holes are located on the different inclined-planes, have also strengthened the intensity of needle point, make dosing crosspointer 5 in piercing process, be difficult for being fractureed.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
