Integrated medicine mixing interface

Abstract

An integrated medicine mixing interface comprising a medicine mixing mouth (1), hard double interfaces (2) and a medicine feed needle (3). The hard double interfaces (2) comprise a base (21), a medicine mixing interface (22) and an infusion interface (23). The medicine mixing mouth (1) and the medicine mixing interface (22) are integrated. When using the integrated medicine mixing interface, it is only necessary to weld the base (21) to the bag body of a soft infusion bag (11) and integrate the medicine mixing mouth (1) with the medicine mixing interface on the hard double interfaces (2) without adopting a hose connection and an easily folding handle, which not only reduces hose installation location, but also avoids welding leakage brought about by hose welding defects. Moreover, the structure is simple and the costs are low.

DETAILED EMBODIMENTS

(7) The present invention is described in detail hereinafter in conjunction with the drawings and specific embodiments.

(8) As shown in FIGS. 1, 2 and 3, an integrated medicine mixing interface includes a medicine mixing nozzle 1, double hard interface 2 and a medicine feeding needle 3. The double hard interface 2 include a base 21, a medicine mixing interface 22 and a transfusion interface 23. The medicine nozzle 1 and the medicine mixing interface 22 are integrally formed.

(9) The medicine feeding needle 3 is a cross-shaped needle (i.e., medicine feeding double needles, a cutting plane in an axis direction of the medicine feeding needle has a “cross-shaped” structure), the upper and lower needle tips of the medicine feeding needle 3 are both of a conical structure, and three needle holes are evenly distributed on a conical surface of the conical structure. The inner wall of a medicine mixing passage formed by the medicine mixing nozzle 1 integrated with the medicine mixing interface 22 is provide with an annular rubber cushion I4, and a lower portion of the cross-shaped needle is snapped into an inner hole of the annular rubber cushion I4, and a base 5 of the cross-shaped needle is located within a medicine mixing snapping body 6 of the medicine mixing nozzle 1. A diaphragm 14 for sealing the medicine mixing passage is provided within the medicine mixing interface 22. Before the base 21 of the double hard interfaces 2 is welded onto the transfusion soft bag 11 to perform medicine mixing (as shown in FIG. 4), the diaphragm 14 may block up the medicine mixing passage, such that the transfusion solvent in the transfusion soft bag 11 is kept sealed and does not contact with the medicine feeding needle 3, which avoids that the transfusion solvent is poured into the medicine mixing snapping body 6 through the medicine feeding needle 3 to cause leakage, and thus not only strictly ensuring the volume of the transfusion solvent in the transfusion soft bag 11, but also avoiding contamination before use. When the diaphragm 14 is punctured by the medicine feeding needle 3, the medicine mixing interface 22 is communicated with the medicine feeding needle 3, thus allowing the transfusion solvent to flow into a medicine container to achieve medicine mixing (as shown in FIG. 5). At this time, the annular rubber cushion I4 replaces the diaphragm 14, which may not only isolate the transfusion solvent to prevent the transfusion solvent from contacting the outside, but also limit the transfusion solution to flow into a medicine container 12 only through the medicine feeding needle 3. Thus, the arrangement of the diaphragm 14 strictly controls the order of opening the medicine mixing passage, and ensures the safety and sanitation in the medicine mixing process. Furthermore, the diaphragm 14 and the medicine mixing interface 22 can be integrated, which is easily implemented by simply process and will not increase the economical burden to customers because of the low cost of the material.

(10) Welding lines 7 are uniformly arranged all over the outer wall of the base 21 (four welding lines are uniformly arranged all over the outer wall of the base 21 according to this example). A projection of the base 21 on its cross section has a boat-shaped structure, and both ends of the base 21 in the boat-shaped structure extend outwardly to form thin sheets 8 with the thickness tapering. In a state that heat welding is performed, the base 21 is more reliably welded to a bag port of the transfusion soft bag 11 by the welding lines 7 on the base 21, and the effect of the sealing between the base 21 and the transfusion soft bag 11 is much better. Moreover, the thin sheets 8 on both sides of the base 21 and the bag port of the transfusion soft bag 11 can be melt together more quickly, which not only increases the welding speed, but also enhances the effect of the sealing between the base 21 and the transfusion soft bag 11.

(11) The medicine mixing snapping body 6 has a hollow cylindrical structure. At least two barb-shaped slip-proof buckle 9 for preventing the medicine container from loosening are symmetrically provided on the inner wall of the medicine mixing snapping body 6. Six slip-proof buckle 9 are symmetrically arranged on the inner wall of the medicine mixing snapping body 6 according to this example. After the medicine container 12 is snapped into the medicine mixing snapping body 6, under the hindering effect of the slip-proof buckle 9, the medicine container 12 may be effectively prevented from escaping or loosening from the medicine mixing snapping body 6 in the opposite direction.

(12) A sealing cover 10 is provided on an upper end of the medicine mixing snapping body 6. Before use, the sealing cover 10 can not only ensure that the medicine mixing snapping body 6, the medicine feeding needle 3 within the medicine mixing snapping body 6 and the medicine mixing passage within the double hard interfaces 2 are in a sealed state, to allow the medicine mixing snapping body 6, the medicine feeding needle 3 within the medicine mixing snapping body 6 and the medicine mixing passage within the double hard interfaces 2 to have good cleanliness before use, but also effectively preserve the sharpness of the upper needle of the medicine feeding needle and the inner structure of the medicine mixing snapping body 6, avoiding the damage during transportation. When in use, it is simply required to remove the sealing cover 10, which is convenient and ensures the cleanliness of the medicine mixing snapping body 6, the medicine feeding needle 3 within the medicine mixing snapping body 6 and the medicine mixing passage within the double hard interfaces 2.

(13) An annular rubber cushion II 13 is provided within the medicine mixing snapping body 6 and above the base 5 of the medicine feeding needle 3. The annular rubber cushion II 13 is sleeved outside the medicine feeding needle 3, and is located between the base 5 and the slip-proof buckle 9. Since the annular rubber cushion II 13 sleeved outside the medicine feeding needle 3 is provided within the medicine mixing snapping body 6 and above the base 5 of the medicine feeding needle 3, and the annular rubber cushion II 13 has good elasticity, when the medicine container 12 is snapped into the medicine mixing snapping body 6 (as shown in FIG. 5), the medicine container 12 may be prevented from loosening by the annular rubber cushion II 13 and the slip-proof buckle 9 on the medicine mixing snapping body 6. The position at which the medicine container 12 is connected to the medicine mixing snapping body 6 by being inserted is sealed completely by the annular rubber cushion II 13, which prevents medicine leakage from occurring during medicine mixing, and strictly ensures the absolute air-tightness in the medicine container after the medicine mixing, and avoids the risk of bacterial infections

(14) Using the integrated medicine mixing interface may include welding the base 21 onto the bag port of the transfusion soft bag 11, and snapping a bottom portion of the medicine feeding needle into the inner hole of the annular rubber cushion I4, as shown in FIG. 4. Mixing the medicine may include removing the sealing cover 10, snapping the medicine container 12 into the medicine mixing snapping body 6, and then pushing the medicine container 12 downwardly, to allow the medicine feeding needle 3 to be push downwardly while a sealing plug of the medicine container 12 is punctured by the top portion of the medicine feeding needle 3, such that the diaphragm 14 within the medicine mixing interface 22 is punctured by the bottom portion of the medicine feeding needle 3, and the base 5 of the medicine feeding needle 3 is finally moved to the bottom portion of the medicine mixing snapping body 6, thereby the medicine container 12 is communicated with the transfusion soft bag 11, as shown in FIG. 5.

(15) Finally, it should be noted that the examples described above is merely to illustrate the technical solution of the present invention and not for limitations, although the present invention is described in detail with reference to preferred examples, it should be understood to an ordinary skilled in the art that the technical solution of the present invention can be modified or substituted equivalently without departing from the spirit and the scope of the technical solution of the present invention, which should be encompassed in the scope defined by the claims of the present invention.
