Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a medicine dispensing and infusion device. Background Art
[0002] Intravenous infusion is a commonly used treatment method in clinical practice. Before infusion, medication dispensing is required. Medication dispensing is to transfer the required measured powder, liquid medicine and other drugs to the infusion bag. Traditional medication dispensing is to transfer drugs with a syringe. The specific operation method is generally to first break the ampoule containing the liquid medicine, then use a syringe to draw the liquid medicine into the empty needle, then insert the syringe needle into the vial containing the powder, and inject the liquid medicine into the vial solvent powder, and finally draw the mixed solution of the liquid medicine and powder into the infusion bag. The traditional medication dispensing method is complicated and inefficient. In the traditional medication dispensing process, the needle and the medicine in the ampoule are exposed to the air, and the medicine may be contaminated by pathogens in the air. When the ampoule is broken, fine glass powder may fall into the liquid medicine, and when the liquid medicine in the ampoule is extracted, these fine glass powders may be drawn into the liquid medicine, causing liquid medicine contamination; and when the needle punctures the rubber cap of the vial, fine rubber particles may enter the syringe to contaminate the liquid medicine. Therefore, the safety of the traditional liquid preparation method is also low. Utility Model Content

[0005] The medicine container comprises a container body and a plug-in sleeve, the plug-in sleeve comprises an inner sleeve section fixedly connected to the container body and an outer sleeve section used to cooperate with the tubular plug on the infusion bag, an elastic sealing sleeve is fixedly arranged in the inner sleeve section, a switch column is arranged in the elastic sealing sleeve, the switch column comprises a sealing section, a leakage section connected to the sealing section and having a smaller diameter than the sealing section, an anti-slip section connected to the leakage section and a pushing section connected to the anti-slip section, the sealing section is sealingly matched with the inner hole surface of the elastic sealing sleeve, an annular groove is formed between the leakage section and the elastic sealing sleeve, the anti-slip section and the elastic sealing sleeve are in extrusion contact, and an axial groove connected to the anti-slip section is arranged on the anti-slip section and connected to the annular groove, the pushing section is located in the outer sleeve section, and the diameter of the pushing section is smaller than the inner diameter of the elastic sealing sleeve.
[0006] Furthermore, there are at least two sealing rings on the tubular plug, and elastic sealing rings are arranged between adjacent sealing rings.
[0007] Furthermore, the tubular plug is covered with a protective cap.
[0008] Beneficial effects of the utility model:
[0009] The infusion and preparation combined device of the utility model can insert the tubular plug on the infusion bag into the outer plug-in sleeve section on the medicine container, and use the tubular plug to push the sealing section of the switch column out of the elastic sealing sleeve, so that the liquid medicine in the infusion bag can enter the medicine container, and then complete the medicine dispensing operation. Compared with the traditional medicine dispensing method of transferring the liquid medicine with a syringe, the infusion and preparation combined device of the utility model can make the medicine dispensing operation simpler and improve the medicine dispensing efficiency. At the same time, the liquid medicine will not be exposed to the air during the medicine dispensing process, and the risk of glass fragments or rubber particles contaminating the liquid medicine in the traditional medicine dispensing method is eliminated, and the medicine dispensing safety is high.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0017] As shown in the figure, the infusion and preparation liquid combination device in this embodiment includes an infusion bag and a medicine container. The infusion bag includes a bag body 1 and a switch valve 2 connected to the bag body, a tubular plug 3 is arranged on the outlet of the switch valve, a sealing ring 4 is arranged on the outer surface of the tubular plug, and a radial notch 5 is arranged at the front end of the tubular plug.
[0018] The medicine container includes a container body 6 and a plug-in sleeve 7, the plug-in sleeve includes an inner plug-in sleeve section 71 fixedly connected to the container body and an outer plug-in sleeve section 72 for cooperating with the tubular plug on the infusion bag, an elastic sealing sleeve 8 is fixedly arranged in the inner plug-in sleeve section, a switch column 9 is arranged in the elastic sealing sleeve, the switch column includes a sealing section 91, a leakage section 92 connected to the sealing section and having a smaller diameter than the sealing section, an anti-slip section 93 connected to the leakage section and a push-up section 94 connected to the anti-slip section, the sealing section is sealed with the inner hole surface of the elastic sealing sleeve, an annular groove 10 is formed between the leakage section and the elastic sealing sleeve, the anti-slip section and the elastic sealing sleeve are in extrusion contact, and an axial groove 95 connected to the annular groove is arranged on the anti-slip section, the push-up section is located in the outer plug-in sleeve section, and the diameter of the push-up section is smaller than the inner diameter of the elastic sealing sleeve.
[0019] When the infusion and preparation liquid combination device in this embodiment is used, the tubular plug 3 on the infusion bag is inserted into the plug sleeve section 72 on the medicine container, and the tubular plug 3 is used to push the push section 94, so that the sealing section 91 is pushed out of the elastic sealing sleeve 8, so that the liquid medicine in the infusion bag can enter the container body 6 of the medicine container through the radial notch 5, the axial groove 95 and the annular groove outside the leakage section 92, and the medicine in the container body 6 is mixed and dissolved with the liquid medicine from the infusion bag, and then flows back into the infusion bag, so that the medicine in the medicine container can be transferred to the infusion bag; in a specific implementation, the medicine in the medicine container can be a powder or an aqueous solution.
