Description

Technical Field

[0001] This invention relates to consumer goods, particularly medical devices, and especially to infusion devices, specifically an infusion container that facilitates medication preparation. Background Technology

[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. Antibiotic preparation, in particular, requires drawing saline or glucose solution from the infusion 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, making the entire procedure cumbersome. Existing infusion containers have rubber stoppers inside the sealing caps. During use, a needle is inserted into the stopper for medication preparation and infusion. While the rubber stoppers provide a good seal and ensure infusion safety, the sealing devices in existing infusion containers have limited functionality, making medication preparation inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an infusion container that facilitates drug preparation, thereby solving the technical problem of inconvenient drug preparation operations in the prior art.

[0004] This invention provides an infusion container for easy medication preparation, comprising a sealed container with an inlet tube at one end and a sealing device thereon. The sealing device includes a cover body containing a rubber stopper. An outer sleeve is provided on the upper side of the cover body, connected to the cover body via a foldable or detachable connection. The outer sleeve has an upward-opening cavity, within which a support is movably disposed. 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 and lower ends of the first and second puncture devices have sharp ends. Each of the first and second puncture devices contains one or more channels, any one of which connects to the sharp ends of both the first and second puncture devices.

[0005] Furthermore, the foldable portion includes a journal disposed between the cover and the outer sleeve, the cross-sectional area of ​​the journal being smaller than the area of ​​the upper side of the cover and the area of ​​the lower side of the outer sleeve, and an annular thin-walled structure being provided on the inner or outer side of the journal.

[0006] Furthermore, the detachable connection includes a first threaded opening on the top of the cover and a second threaded opening on the bottom of the outer cover, wherein the first threaded opening and the second threaded opening are screwed together.

[0007] Alternatively, the detachable connection may include a buckle located on the upper side of the cover, which snaps into the bottom inner side of the outer cover.

[0008] 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.

[0009] 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 outer side of the bracket is provided with multiple evenly distributed notches.

[0010] 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.

[0011] Furthermore, the first puncture device, the second puncture device, and the support are an integrated structure, the first puncture device and the second puncture device are coaxially arranged, and the number of channels is two.

[0012] Furthermore, a sealing element, which is a protective film, is provided at the upper end of the outer casing.

[0013] Furthermore, the sealed container is a bottle or a soft bag.

[0014] The working principle of this invention is as follows: Saline or glucose injection solution is stored in a sealed container. When in 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 pierces the stopper inside the cap and inserts into the infusion tube. Then, the sealed container is inverted, and the container is squeezed to allow the liquid inside to pass through the channels in the first and second puncture devices into the vial to dissolve the medication. The dissolved medication then passes through the channels and is inverted again into the sealed container. If multiple medications need to be mixed, the vial can be removed from the first puncture device, and the above operation can be repeated to dissolve multiple medications using the liquid in the sealed container. After the medication is prepared, the outer casing is removed from the cap through the detachable or removable connection part, and the infusion needle is inserted through the stopper for infusion.

[0015] Compared with existing technologies, the present invention has positive and significant advantages. The present invention features an outer casing for the sealing device, inside which is a support. The first and second puncture devices of the support puncture the rubber stopper inside the vial and cap, allowing the medication to flow through the channels within the first and second puncture devices. No other instruments are required, facilitating medication preparation. During infusion, the outer casing can be removed to continue using the rubber stopper, making the operation simple.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0029] Example 1

[0030] like Figures 1-9 As shown, this embodiment provides an infusion container for easy medication preparation, including a sealed container. One end of the sealed container is provided with an inlet tube 19, and the inlet tube 19 is provided with a sealing device. The sealing device is characterized in that: the sealing device includes a cover body 1, a rubber stopper 2 is provided inside the cover body 1, an outer sleeve 3 is provided on the upper side of the cover body 1, the outer sleeve 3 is connected to the cover body 1 through a folding part 9, the outer sleeve 3 has an upward-opening cavity 4, a support 5 is movably arranged in the cavity 4, a first puncture device 6 is provided on the upper side of the support 5, and a second puncture device 7 is provided on the lower side of the support 5. The upper end of the first puncture device 6 and the lower end of the second puncture device 7 are both provided with sharp ends. The first puncture device 6 and the second puncture device 7 are provided with one or more channels 8, and any one of the channels 8 is connected to the sharp end of the first puncture device 6 and the sharp end of the second puncture device 7.

[0031] Furthermore, the foldable portion 9 includes a journal 91 disposed between the cover 1 and the outer sleeve 3. The cross-sectional area of ​​the journal 91 is smaller than the area of ​​the upper side of the cover 1 and the area of ​​the lower side of the outer sleeve 3. An annular thin-walled structure 92 is provided on the inner or outer side of the journal 91. The journal 91 reduces the cross-sectional area, allowing the outer sleeve 3 to be folded down at the thin-walled structure 92 with a smaller force.

[0032] Furthermore, a guide portion 11 is provided on the side of the support 5. The guide portion 11 fits against the inner wall of the outer sleeve 3. The inner wall of the outer sleeve 3 is provided with a first limiting protrusion 12 and a second limiting protrusion 13 spaced from top to bottom. The guide portion 11 of the support 5 is located between the first limiting protrusion 12 and the second limiting protrusion 13 or between the second limiting protrusion 13 and the inner bottom surface of the outer sleeve 3. By fitting the guide portion 11 against the inner wall of the outer sleeve 1, the support 5 can move along the axial direction of the outer sleeve 1, facilitating the second puncture device 7 to puncture the rubber stopper 2. When the infusion container is stored, the guide portion 11 of the stent 5 is located between the first limiting protrusion 12 and the second limiting protrusion 13 to prevent the stent 5 from moving in the cavity 4. When the medicine is prepared and infused, the stent 5 is pressed down, and the second puncture device 7 punctures the rubber stopper 2 and enters the infusion container. The guide portion 11 of the stent 5 is located between the second limiting protrusion 13 and the inner bottom surface of the outer sleeve 3, and the second limiting protrusion 13 limits the guide portion 11.

[0033] Furthermore, the first limiting protrusion 12 and the second limiting protrusion 13 are annular protrusions, and the upper surfaces of the first limiting protrusion 12 and the second limiting protrusion 13 are conical surfaces. Multiple evenly distributed notches 14 are provided on the outer side of the bracket 5. The conical upper surfaces of the first limiting protrusion 12 and the second limiting protrusion 13 facilitate the installation and pressing of the bracket 5. During infusion container installation, the bracket 5 needs to be pressed into the lower side of the first limiting protrusion 12; during use, the bracket 5 needs to be pressed into the lower side of the second limiting protrusion 13. The notches 14 reduce the solid area of ​​the bracket 5, making it easier for the bracket 5 to deform and facilitating its pressing.

[0034] Furthermore, the upper side of the support 5 is provided with a third limiting protrusion 15. The third limiting protrusion 15 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 6, and the annular protrusions are centered on the first puncture device 6. The third limiting protrusion 15 serves to guide and limit the vial 20 when it is inserted into the first limiting protrusion 12.

[0035] Furthermore, the first puncture device 6, the second puncture device 7, and the support 5 are an integral structure, with the first puncture device 6 and the second puncture device 7 arranged coaxially, and the number of channels 8 is two. The coaxial arrangement of the first puncture device 6 and the second puncture device 7 facilitates the fabrication of the channels 8 within the first puncture device 6 and the second puncture device 7, ensuring that the channels 8 are in a straight line. Having two channels 8 allows for convenient fluid flow within both channels.

[0036] Furthermore, a sealing element 16, which is a protective film, is provided at the upper end of the outer casing 3. The protective film ensures that the inside of the outer casing 3 remains sterile during transportation and storage, thereby ensuring that the entire infusion container can be opened when needed.

[0037] Furthermore, the sealed container is either a bottle 17 or a flexible bag 18. Both the bottle 17 and the flexible bag 18 are commonly used infusion sealing containers, easy to manufacture, such as... Figure 1 The diagram shown is a structural schematic of an embodiment using a bottle as a sealed container. Figure 2 The diagram shown is a structural schematic of an embodiment using a soft bag as a sealed container.

[0038] The usage method of this embodiment is as follows: Figures 7-9 As shown, first tear off the protective film at the top of the outer jacket 3, as follows. Figure 7 As shown, align the sealing rubber stopper of vial 20 with the first puncture device 6, press down on vial 20 to allow the first puncture device 6 to pierce the sealing rubber stopper and insert into vial 20, then proceed as follows. Figure 8The second puncture device 7, as shown, pierces the rubber stopper 2 inside the cap 1 and inserts into the inlet tube 19. Then, the sealed container is inverted, and the container is squeezed to allow the liquid inside to pass through the channels 8 in the first and second puncture devices 6 and enter the vial 20 to dissolve the medication. The dissolved medication then passes through channel 8 and is inverted again into the sealed container. If multiple medications need to be mixed, the vial 20 can be removed from the first puncture device 6, and the above operation can be repeated to dissolve multiple medications using the liquid in the sealed container. After the medication is prepared, as shown... Figure 9 As shown, the outer cover 3 is removed from the cover 1, and the infusion needle is inserted through the rubber stopper 2 for infusion.

[0039] Example 2

[0040] like Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the outer sleeve 3 of the sealing device is connected to the cover 1 via a detachable connecting part 10. The detachable connecting part 10 includes a first threaded opening 101 provided on the top of the cover 1 and a second threaded opening 102 provided on the bottom of the outer sleeve 3. The first threaded opening 101 and the second threaded opening 102 are screwed together. When the first threaded opening 101 is an internal thread, the second threaded opening 102 is an external thread; when the first threaded opening 101 is an external thread, the second threaded opening 102 is an internal thread.

[0041] In this embodiment, the cover 1 and the outer sleeve 3 are assembled by screwing together the first threaded port 101 and the second threaded port 102. After the medicine solution is prepared, the outer sleeve 3 is unscrewed and the infusion needle is inserted into the rubber stopper 2 for infusion.

[0042] Example 3

[0043] like Figure 11 As shown, the difference between this embodiment and embodiment 1 is that the outer sleeve 3 of the sealing device in this embodiment is connected to the cover 1 through a detachable connecting part 10. The detachable connecting part 10 includes a buckle 103 disposed on the upper side of the cover 1, and the buckle 103 is snapped into the bottom inner side of the outer sleeve 3.

[0044] In this embodiment, the cover 1 and the outer cover 3 are assembled by the buckle 103. After the medicine is prepared, the outer cover 3 is removed and the infusion needle is inserted into the rubber stopper 2 for infusion.
