[0002] A medical infusion bag is a container used for intravenous infusion. It temporarily stores and mixes nutrient solutions and therapeutic drugs before delivering them intravenously to the patient. The materials used in medical infusion bags meet strict requirements; they undergo screening and testing to ensure they are non-toxic, harmless, and do not release harmful substances during use.

[0003] Chinese Patent CN217245581U discloses a high-safety medical infusion bag, including an infusion chamber. An infusion port is fixedly connected to the bottom outer wall of the infusion chamber, and a sealing plug is slidably connected to the bottom of the infusion port. A mixing assembly is provided at the upper end of the infusion chamber. The mixing assembly includes a mixing chamber, a storage component, and an infusion connection component. The storage component is located at the left end of the top outer wall of the mixing chamber, and its bottom end is fixedly connected to the top inner wall of the mixing chamber through the infusion connection component. This infusion bag, through the coordinated action of the mixing chamber, the powder storage bottle, and the infusion connection component, allows for complete mixing of the medication within the mixing chamber. This effectively prevents frequent needle insertion into the infusion port by medical personnel, thus contaminating the infusion port and reducing the likelihood of adverse symptoms in patients.

[0004] However, the above technical solution has the following shortcomings: when the infusion bag mixes the drug powder and glucose or saline through the infusion connecting component, the mixing chamber needs to be shaken to make the drug solution mix quickly. However, shaking may cause the bulb core to rotate, resulting in excessive drug powder entering the mixing chamber or unevenly mixed drug solution entering the interior of the infusion chamber. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a medical high-efficiency antibacterial infusion bag, which can prevent excessive powder from entering the mixing bag or unevenly mixed medicine from entering the inside of the infusion bag when shaking and mixing the medicine, thus ensuring the practicality of the infusion bag.

[0022] Example 1

[0023] like Figures 1-5 As shown in the figure, the medical high-efficiency antibacterial infusion bag proposed in this embodiment includes an infusion bag 1 and a limiting mechanism; a mixing bag 2 is provided above the infusion bag 1, and a powder bottle 21 is provided on the mixing bag 2; a connecting tube 3 is provided to connect the infusion bag 1 and the mixing bag 2; a ball core 4 is rotatably connected inside the connecting tube 3; the ball core 4 has a through hole 6; the diameter of the through hole 6 is adapted to the connecting tube 3; a rotating rod 5 is provided on the ball core 4; the rotating rod 5 is rotatably connected to the connecting tube 3.

[0024] A sealing ring 7 is coaxially mounted on the rotating rod 5, and the sealing ring 7 is rotatably mounted inside the connecting pipe 3. A knob 8 is mounted on the rotating rod 5.

[0025] The limiting mechanism includes a connecting rod 10 mounted on the rotating rod 5, a fixing frame 9 mounted on the infusion bag 1, a slide rod 11 slidably connected to the fixing frame 9, a wedge block 12 mounted on the slide rod 11, and a spring 13 mounted on the wedge block 12 and the fixing frame 9 respectively. The fixing frame 9 is provided with a groove for the connecting rod 10 to be inserted. The wedge block 12 and the fixing frame 9 are slidably connected. The spring 13 is sleeved on the slide rod 11. The slide rod 11 is provided with a ball gripping device 15. The wedge block 12 is provided with a guide block 14. The fixing frame 9 is provided with a sliding groove for the guide block 14 to slide.

[0026] The mixing bag 2 is equipped with a limiting mechanism, and both the mixing bag 2 and the powder bottle 21 are equipped with baffles 16. The baffles 16 can position the ball core 4 through hole 6 and the connecting tube 3.

[0027] In this embodiment, the ball core 4 is rotated by rotating the rotating rod 5. When the through hole 6 of the ball core 4 is connected with the connecting pipe 3, the powder can enter the mixing bag 2 or the liquid can enter the infusion bag 1 to achieve flow control of the powder and liquid. The glucose or saline solution to be mixed can be added to the mixing bag 2 through the filling port at the rear end of the mixing bag 2. After the addition is completed, the filling port is sealed and protected. Then, the rotating rod 5 is rotated to close the connecting tube 3. At the same time, the rotating rod 5 drives the connecting rod 10 to rotate and compresses the inclined surfaces of the connecting rod 10 and the wedge block 12. After being compressed, the wedge block 12 slides into the interior of the fixing frame 9 in conjunction with the compression action of the guide block 14. At this time, the spring 13 is compressed until the connecting rod 10 is at the bottom of the groove. At this time, the wedge block 12 returns under the action of the spring 13, locking the connecting rod 10, thereby locking the rotation direction of the rotating rod 5. This prevents the rotating rod 5 from driving the ball core 4 to rotate when shaking and mixing the medicine, which would cause excessive powder to enter the mixing bag 2 or unevenly mixed medicine to enter the interior of the infusion bag 1. The operation is simple and convenient and has good practicality.

[0028] Example 2

[0029] like Figure 1 and Figure 4 As shown, this embodiment proposes a medical high-efficiency antibacterial infusion bag. Compared with the first embodiment, in this embodiment, the infusion bag 1 and the mixing bag 2 are provided with a support assembly. The support assembly includes a first fixing member 17 and a second fixing member 18 respectively disposed on the infusion bag 1 and the mixing bag 2, a support rod 19 that passes through the second fixing member 18 and is inserted into the first fixing member 17, and an insertion rod 20 that is threadedly connected to the support rod 19. The insertion rod 20 and the second fixing member 18 abut against each other.

[0030] In this embodiment, the support component is used to prevent the infusion bag 1 and the mixing bag 2 from folding together and to provide support. When installing the support component, first insert the support rod 19 through the second fixing member 18 and then insert its bottom end into the first fixing member 17. Then screw the threaded part of the insertion rod 20 into the inside of the support rod 19 until the head of the insertion rod 20 abuts against the second fixing member 18, thus completing the fixed installation. The operation is simple and convenient.

The hanging ring 23 is used to hang the infusion bag 1 and the mixing bag 2, and the sealing cap 22 and the sealing plug 25 are respectively used to seal the powder bottle 21 and protect and isolate the infusion port 24.

[0033] Both the infusion bag 1 and the mixing bag 2 include an inner bag layer 26, an outer bag layer 27, a barrier layer 28, and a sterilization layer 29 distributed from the inside out. The barrier layer 28 is made of silicon dioxide, and the sterilization layer 29 is made of titanium dioxide, which makes the infusion bag 1 and the mixing bag 2 transparent, light-proof, and sterilization, while also providing good protection and barrier function.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
