[0002] Before a patient receives an intravenous infusion, medical staff must prepare the medication solution, and this preparation must be performed in a sterile environment. Antibiotics, in particular, require drawing saline or glucose solution from the container using a syringe and injecting it into a vial. After the drug dissolves, it is then drawn from the vial and injected into the infusion container. If multiple medications need to be administered simultaneously, this process must be repeated. The entire procedure is cumbersome and prone to contamination. Summary of the Invention

[0003] The purpose of this invention is to provide an infusion device for preparing medicinal solutions, which solves the technical problems of complex preparation processes and easy contamination in the prior art.

[0004] This invention relates to an infusion device for preparing pharmaceutical solutions, comprising a pharmaceutical solution preparation device and an infusion container. The pharmaceutical solution preparation device includes an outer casing with an upward-opening cavity. A support is movably disposed within the cavity. A first puncture device is disposed on the upper side of the support, and a second puncture device is disposed on the lower side of the support. Both the upper end of the first puncture device and the lower end of the second puncture device are provided with sharp ends. The inner sides of the first and second puncture devices are provided with one or more channels, any one of which connects to the sharp end at the top of the first puncture device and the sharp end at the bottom of the second puncture device. An elastomeric seal is disposed below the cavity of the outer casing, and the lower side of the outer casing is connected to the infusion container.

[0005] Furthermore, the side of the bracket is provided with a guide portion, which fits against the inner wall of the outer sleeve. The inner wall of the outer sleeve is provided with a first limiting protrusion and a second limiting protrusion at intervals from top to bottom. The guide portion of the bracket is located between the first limiting protrusion and the second limiting protrusion or between the second limiting protrusion and the inner bottom surface of the outer sleeve.

[0006] Furthermore, the first and second limiting protrusions are annular protrusions, the upper surfaces of the first and second limiting protrusions are conical surfaces, and the side of the bracket is provided with multiple evenly distributed notches.

[0007] Furthermore, the upper side of the bracket is provided with a third limiting protrusion, which is at least two protrusions or annular protrusions. The protrusions are evenly distributed in annular shape on the circumference with the first puncture device as the center, and the annular protrusions are with the first puncture device as the center.

[0008] Furthermore, the upper end of the outer casing is provided with an outer casing seal, which is a protective film.

[0009] Furthermore, the first puncture device, the second puncture device, and the support are an integrated structure, with the first puncture device and the second puncture device arranged coaxially, and the number of channels is two.

[0010] Furthermore, the lower side of the outer sleeve is provided with a journal, the elastomeric seal is disposed inside the journal, the elastomeric seal is provided with a through hole in the middle, and the second puncture device is coaxially disposed with the through hole.

[0011] Furthermore, a lifting device is provided on the outside of the outer jacket. The lifting device is inverted U-shaped, and its two ends are hinged to the outer wall of the outer jacket.

[0012] Furthermore, the infusion container includes a sealed container, the lower end of which is provided with a first inlet tube, the lower end of which is provided with a sealing cap, and the drug preparation device is connected to the upper end of the sealed container.

[0013] Furthermore, the upper end of the sealed container is provided with a second inlet tube, the bottom of the medicine preparation device is provided with a cover, the cover is connected to the second inlet tube, and the sealed container is a bottle or a soft bag.

[0014] The working principle of the drug preparation device of this invention is as follows: Physiological saline or glucose injection solution is stored in an infusion container. During use, the sealing stopper of the vial is aligned with the first puncture device. The vial is pressed down, causing the first puncture device to pierce the sealing stopper and insert into the vial. The second puncture device then passes downwards through the elastic seal to pierce the seal of the infusion container and inserts into the infusion container. The infusion volume is then inverted, and the infusion container is squeezed to allow the liquid inside to flow through the channels in the first and second puncture devices into the vial to dissolve the drug solution. The dissolved drug solution then flows through the channels back into the infusion container. At this point, the vial remains above the support, and infusion can be performed. If multiple drugs need to be mixed, the vial can be removed from the first puncture device, and the above operation can be repeated to dissolve multiple drugs using the liquid in the infusion container.

[0015] Compared with existing technologies, the present invention has positive and significant effects. The drug preparation device of the present invention has a bracket with a first puncture device and a second puncture device inside the outer casing. During use, the vial and infusion container are punctured for operation, which facilitates rapid preparation of the drug solution. The sealing rubber stopper of the vial seals with the first puncture device, and the elastomeric seal seals the outside of the second puncture device, so that the infusion liquid does not come into contact with the outside environment, preventing leakage and external contamination during the drug preparation process.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0024] like Figures 1-6 As shown, a drug preparation device of the present invention includes a drug preparation device and an infusion container. The drug preparation device includes an outer casing 1, which has an upward-opening cavity 2. A support 3 is movably disposed within the cavity 2. A first puncture device 4 is disposed on the upper side of the support 3, and a second puncture device 5 is disposed on the lower side of the support 3. Both the upper end of the first puncture device 4 and the lower end of the second puncture device 5 are provided with sharp ends. The inner sides of the first puncture device 4 and the second puncture device 5 are provided with one or more channels 6, and any one of the channels 6 connects to the sharp end at the top of the first puncture device 4 and the sharp end at the bottom of the second puncture device 5. An elastomeric seal 7 is disposed below the cavity 2 of the outer casing 1, and the lower side of the outer casing 1 is connected to the infusion container.

[0025] Furthermore, the side of the stent 3 is provided with a guide portion 8, which fits against the inner wall of the outer sleeve 1. The inner wall of the outer sleeve 1 is provided with a first limiting protrusion 9 and a second limiting protrusion 10 spaced from top to bottom. The guide portion 8 of the stent 3 is located between the first limiting protrusion 9 and the second limiting protrusion 10 or between the second limiting protrusion 10 and the inner bottom surface of the outer sleeve 1. By fitting the guide portion 8 against the inner wall of the outer sleeve 1, the stent 3 can move along the axial direction of the outer sleeve 1, facilitating the passage of the second puncture device 5 through the elastomeric seal 7. During storage, the guide portion 8 of the stent 3 is located between the first limiting protrusion 9 and the second limiting protrusion 10 to prevent the stent 3 from moving within the cavity 2. During drug preparation and infusion, the stent 3 is pressed down, and the second puncture device 5 passes through the elastomeric seal 7 and enters the infusion container. The guide portion 8 of the stent 3 is positioned between the second limiting protrusion 10 and the inner bottom surface of the outer sleeve 1.

[0026] Furthermore, the first limiting protrusion 9 and the second limiting protrusion 10 are annular protrusions, and the upper surfaces of the first limiting protrusion 9 and the second limiting protrusion 10 are conical surfaces. The side of the bracket 3 is provided with multiple evenly distributed notches 11. The conical upper surfaces of the first limiting protrusion 9 and the second limiting protrusion 10 facilitate the installation and pressing of the bracket 3. When the bracket 3 is pressed into the second limiting protrusion 9, the notches 11 reduce the solid area of ​​the bracket 3, making it easier for the bracket 3 to deform and facilitating the pressing of the bracket 3 into the bottom of the cavity 2.

[0027] Furthermore, the upper side of the support 3 is provided with a third limiting protrusion 12. The third limiting protrusion 12 consists of at least two protrusions or annular protrusions. The protrusions are evenly distributed in annular shape on a circumference centered on the first puncture device 4, and the annular protrusions are centered on the first puncture device 4. The third limiting protrusion 12 serves to guide and limit the vial 22 when it is inserted into the first limiting protrusion 9.

[0028] Furthermore, the upper end of the outer casing 1 is provided with an outer casing seal 13, which is a protective film. The protective film ensures that the interior of the drug preparation device remains sterile during transportation and storage, and can be opened when needed.

[0029] Furthermore, the first puncture device 4, the second puncture device 5, and the support 3 are an integral structure, with the first puncture device 4 and the second puncture device 5 arranged coaxially, and there are two channels 6. The coaxial arrangement of the first puncture device 4 and the second puncture device 5 facilitates the fabrication of the channels 6 within the first puncture device 4 and the second puncture device 5, ensuring that the channels 6 are in a straight line. Having two channels 6 allows for convenient fluid flow within both channels.

[0030] Furthermore, a journal 14 is provided on the lower side of the outer sleeve 1, and the elastomeric seal 7 is disposed within the journal 14. A through hole 15 is provided in the middle of the elastomeric seal 7, and the second puncture device 5 is coaxially arranged with the through hole 15. The journal 14 can support the elastomeric seal 7, maintain the position of the elastomeric seal 7, and enable the elastomeric seal 7 to better perform its sealing function. The through hole 15 facilitates the passage of the second puncture device 8 through the elastomeric seal 7, and the coaxial arrangement of the second puncture device 5 with the through hole 15 facilitates the passage of the second puncture device 5 through the through hole 15 of the elastomeric seal 7 when the support 3 moves linearly.

[0031] Furthermore, a lifting device 16 is provided on the outside of the outer casing 1. The lifting device 16 is inverted U-shaped, and its two ends are hinged to the outer wall of the outer casing 1. The lifting device 16 can be used to suspend the drug preparation device during infusion, facilitating infusion.

[0032] Furthermore, the infusion container includes a sealed container 17, with a first port 18 at its lower end and a sealing cap 19 at its lower end. The drug preparation device is connected to the upper end of the sealed container 17. At least one of the following locations—the bottom of the drug preparation device and the connection point between the sealed container 17 and the drug preparation device—is sealed to prevent liquid from entering the drug preparation device before use. During use, the second puncture device 5 on the lower side of the support 3 of the drug preparation device punctures the seal to enter the sealed container 17.

[0033] Furthermore, the upper end of the sealed container 17 is provided with a second inlet tube 20, the bottom of the medicine preparation device is provided with a cover 21, the cover 21 is connected to the second inlet tube 20, and the sealed container 17 is a bottle or a soft bag.

[0034] When using this invention, Figure 1 The diagram shows the storage status of an infusion set, with saline or glucose injection solution stored in the infusion container. Figure 2Before preparing the medication, first open the outer sealing member 13, then align the sealing rubber stopper of the vial 22 with the first puncture device 4, then press down the vial 22 to puncture the sealing rubber stopper with the first puncture device 4 and insert it into the vial 22. The second puncture device 5 then passes downwards through the elastic sealing member 7 to puncture the seal of the infusion container and inserts into the infusion container. Then, invert the infusion container and squeeze it to allow the liquid inside to flow through the channels 6 inside the first and second puncture devices 4 and into the vial 22 to dissolve the medication. The dissolved medication then flows through the channels 6 and inverts again into the infusion container. At this time, the vial 22 remains above the support 3. If multiple medications need to be mixed, the vial 22 can be removed from the first puncture device 4, and the above operation can be repeated to dissolve multiple medications with the liquid in the infusion container. After the medication is prepared, insert one end of the infusion needle into the sealing cap 19 of the first port tube 18 for infusion.
