Before transfusion, medical staff often need to mix the medicine into a transfusion bag after dissolving and then drip the medicine on a patient, and the medicine dispensing mode is more, for example, a syringe is used for directly dispensing medicine or a special sterile medicine dispenser is used, and the types of the sterile medicine dispensers are various.
The appearance of the connecting sleeve type sterile medicine dispenser greatly simplifies the medicine dispensing process of medical staff, and only needs to be turned upside down in the medicine dispensing process to squeeze the infusion bag, so that the infusion bag is simple and convenient. One end of the sterile dispensing device is provided with a connecting sleeve connected to a penicillin bottle, one needle tube is arranged in the connecting sleeve and used for penetrating a rubber plug of the penicillin bottle, the other end of the sterile dispensing device is provided with a connecting sleeve fixed to a rubber plug of an infusion bag, the other needle tube penetrates through the rubber plug of the infusion bag, and the penicillin bottle is communicated with the infusion bag through the two needle tubes. When in use, the infusion bag is high Yu Xilin bottles and repeatedly extruded, so that the liquid in the infusion bag enters the penicillin bottle and fully dissolves or mixes the medicines in the penicillin bottle, and then the penicillin bottle is higher than the infusion bag, and the actions are repeated until the liquid medicine in the penicillin bottle is completely pumped back into the infusion bag.
The opening ends of the infusion bags are usually provided with rubber plugs, however, the structures of the rubber plugs among the infusion bags with different specifications are different, for example, 1 jack is preset in the central area of the rubber plug in some infusion bags, 2-3 jacks are preset in the rubber plug (non-central area), and no jack is preset in some infusion bags. Because the structure matching requirement of adapter sleeve and infusion bag plug is very high, many dosage apparatus only are equipped with the needle tubing and do not have the adapter sleeve, and other problems have been brought to the unavoidable when above-mentioned structure improves the compatibility of matching, for example probably have the liquid medicine overflow and pollute environment or liquid medicine itself in the dispensing process, influence medical personnel and patient's safety.
The Chinese patent document CN205198574U discloses a connecting sleeve type sterile dispensing device, which has a structure of double connecting sleeves, wherein a protrusion for a buckle is arranged in each connecting sleeve, and the connecting sleeve can be firmly connected with a penicillin bottle and an infusion bag with a corresponding caliber. When the infusion bag is applied to an infusion bag with 2-3 jacks preset, the axis of the infusion bag rubber plug is deviated from the central area of the bottom of the corresponding connecting sleeve, so that the connecting sleeve cannot be embedded into and fix the infusion bag rubber plug, and the universality is limited to a certain extent.

The radius r of the circular arc of the second auxiliary protrusion 14 is smaller than the distance between the second auxiliary protrusion 14 and the first needle tube 4, and the maximum distance D' =3.5 cm between the circular arcs of the first auxiliary protrusion 13 and the second auxiliary protrusion 14.
Referring to fig. 8, the aseptic dispensing device of the present embodiment can use the second auxiliary projection 14 to assist in fixing when applied to an infusion bag with 3 preset insertion holes for the rubber stopper.
Referring to fig. 9, with respect to the aseptic dispensing device of fig. 6, the aseptic dispensing device of the present embodiment can use the first auxiliary projection 13 to assist in fixation when applied to an infusion bag with a rubber stopper preset with 1 insertion hole.
Compared with other embodiments, the sterile dispensing device of the embodiment can better fix infusion bags with preset 1 jack, and meanwhile, the use of other types of infusion bags is not affected.
Further, as shown in fig. 2, in a preferred embodiment of the present application, the first needle tube 4 is provided with an annular protrusion 41, and the annular protrusion 41 is located between the passage opening of the first needle tube 4 and the sleeve bottom 3, and the passage opening of the first needle tube 4 is opened to the annular protrusion 41.
Fig. 10 is a cross-sectional view showing the infusion dispensing device according to the present embodiment after the infusion dispensing device is engaged with the plug of the infusion bag. The annular bulge 41 is clamped on the inner side of the rubber plug of the infusion bag, so that the infusion bag can be prevented from slipping down in the use process, liquid leakage is caused, and the infusion bag can be smoothly pulled out from the dispensing device after the dispensing is finished. The upper and lower ends of the annular projection 41 are arc-shaped and smoothly transition with the needle surface. The channel opening of the first needle tube 4 is opened to the annular bulge 41 and is basically flush with the inner side of the rubber plug of the infusion bag, which is more beneficial to the full mixing of the liquid medicine through the first needle tube 4 and the second needle tube 5.
The foregoing is merely illustrative of the present application and is not intended to limit the scope of the application. Any equivalent alterations, modifications and combinations thereof will be effected by those skilled in the art without departing from the spirit and principles of this application, and it is intended to be within the scope of the application.
