[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0033] The following will be described in conjunction with Figures 1 to 4 , and the connecting pipe 100 for a contrast agent filling machine provided by the embodiments of the present application will be described in detail through specific embodiments.

[0034] Please refer to Figures 1 to 4 , Figure 1 which is a schematic structural diagram of the connecting pipe for a contrast agent filling machine provided by the present utility model; Figure 2 which is a sectional view of the connecting pipe for a contrast agent filling machine provided by the present utility model; Figure 3 which is Figure 2 an enlarged view of part A in Figure 4 which is Figure 2 an enlarged view of part B in. The connecting pipe 100 for a contrast agent filling machine provided by one embodiment of the present utility model includes an infusion pipe 10, a first bottle piercer 20 and a second bottle piercer 30. The first bottle piercer 20 is located at one end of the infusion pipe 10, and the first bottle piercer 20 is used to connect with a liquid medicine filling machine so that the liquid medicine filling machine is connected to the outside air; the second bottle piercer 30 is located at the other end of the infusion pipe 10, and the second bottle piercer 30 is used to connect with a medicine bottle so that the medicine bottle is connected to the outside air; wherein, the liquid medicine in the liquid medicine filling machine can be automatically injected into the medicine bottle in sequence through the first bottle piercer 20, the infusion pipe 10 and the second bottle piercer 30.

[0035] The infusion tube 10 is used to transport liquid. The first bottle piercer 20 is located at one end of the infusion tube 10 and is used to connect with the liquid medicine filling machine. The first bottle piercer 20 can connect the liquid medicine filling machine with the outside air to achieve gas balance and the injection of liquid medicine. The second bottle piercer 30 is located at the other end of the infusion tube 10 and is used to connect with the medicine bottle. The second bottle piercer 30 can connect the medicine bottle with the outside air to achieve the injection and flow of liquid medicine. The liquid medicine in the liquid medicine filling machine sequentially passes through the first bottle piercer 20, the infusion tube 10 and the second bottle piercer 30 and is automatically injected into the medicine bottle. The liquid medicine flows through the infusion tube 10 from the liquid medicine filling machine and enters the medicine bottle through the first bottle piercer 20, realizing the filling of the liquid medicine in the medicine bottle. Through such a setting, the automatic process of liquid medicine filling can be realized, ensuring that the liquid medicine can be accurately injected into the medicine bottle and maintaining the gas balance in the medicine bottle. This can improve the efficiency and accuracy of contrast agent filling and ensure the quality and safety of the liquid medicine.

[0036] In some embodiments, the first bottle piercer 20 is located at the bottom of the liquid medicine filling machine. The liquid medicine filling machine includes a liquid medicine peristaltic pump, and the first bottle piercer 20 is connected to the liquid medicine peristaltic pump. By arranging the first bottle piercer 20 at the bottom of the liquid medicine filling machine, the liquid medicine in the liquid medicine filling machine can flow downward under the action of its own gravity and thus enter the infusion tube 10 through the first bottle piercer 20, and then enter the liquid medicine through the second bottle piercer 30 on the infusion tube 10, thereby realizing the flow of the liquid medicine and enabling the liquid medicine in the liquid medicine filling machine to automatically flow into the medicine bottle. Moreover, arranging the first bottle piercer 20 at the bottom can reduce the generation of bubbles. Since the liquid medicine peristaltic pump is located at the bottom, the liquid medicine can flow more evenly during the process of entering the bottle, reducing the generation of bubbles and ensuring the quality of the liquid medicine.

[0037] In some embodiments, the second bottle piercer 30 is located at the top of the medicine bottle and is connected to the medicine bottle. The bottom of the liquid medicine is used for circulating the liquid medicine so that the liquid medicine can be injected into the human body through the medicine bottle. By arranging the second bottle piercer 30 at the top of the medicine bottle, the liquid medicine can enter the medicine bottle through the second bottle piercer 30 from the top of the medicine bottle, thus not affecting the transmission of the liquid medicine at the bottom of the medicine bottle.

[0038] In some embodiments, the first bottle piercer 20 includes a first needle 21. The first needle 21 includes a first infusion channel 211. One end of the first infusion channel 211 is connected to the liquid medicine peristaltic pump, and the other end is connected to the infusion tube 10. The first bottle piercer 20 includes the first needle 21, and the first needle 21 includes the first infusion channel 211. One end of the first infusion channel 211 is connected to the liquid medicine peristaltic pump, and the other end is connected to the infusion tube 10. Through such a setting, the liquid medicine can flow from the liquid medicine peristaltic pump into the first infusion channel 211 of the first needle 21 and enter the infusion tube 10 through the first bottle piercer 20, and then be transported to the position where the liquid medicine needs to be injected. It can ensure the accurate transportation and control of the liquid medicine.

[0039] In some embodiments, a first air inlet channel 212 is further formed in the first needle 21. The first air inlet channel 212 is arranged separately from the first infusion channel 211. A first air cavity 213 is formed in the needle, and the first air cavity 213 is in communication with the first air inlet channel 212.

[0040] The first infusion channel 211 and the first air inlet channel 212 are arranged separately. By separating the first air inlet channel 212 and the first infusion channel 211, air, bubbles or other contaminants can be prevented from entering the liquid medicine. This can ensure the purity and safety of the liquid medicine, avoid contamination of the medicine, and thus ensure the quality and effect of the treatment or production process. Separating the first air inlet channel 212 and the first infusion channel 211 can ensure that the liquid medicine has a separate and unobstructed flow channel during transportation. This can better control the flow rate and flow volume of the liquid medicine, ensure the accurate transportation and control of the liquid medicine, and meet the requirements for drug transportation in the medical or production process. By arranging the first air inlet channel 212 separately from the first infusion channel 211, it is more convenient to discharge the air entering the inside of the needle. During the injection of the liquid medicine, the air can enter the first air cavity 213 through the first air inlet channel 212 without directly contacting the liquid medicine. This can reduce or avoid the generation of bubbles and ensure the quality and effect of the liquid medicine injection.

[0041] In this embodiment, the first balloon is in communication with the first air inlet channel 212, and air can enter and be discharged during the liquid medicine filling process. Through the first air inlet channel 212, air can enter the first air cavity 213, making the injection of the liquid medicine smoother. For example, when the air pressure in the liquid medicine filling machine is too high, the air in the liquid medicine filling machine can enter the first air cavity 213 through the first air inlet channel 212 and be discharged through the first air cavity 213. If the air pressure in the liquid medicine filling machine is too low, the outside air can enter the first air inlet channel 212 through the first air cavity 213 and enter the liquid medicine filling machine through the first air inlet channel 212. Through the communication between the air cavity and the first air inlet channel 212, the air pressure balance in the liquid medicine filling machine is achieved.

[0042] In some embodiments, a first air inlet structure 214 is arranged in the first air cavity 213. The first air inlet structure 214 includes a first upper cover 2141, a first breathable membrane 2142, and a silica gel part 2143. The silica gel part 2143 is located in the first air cavity 213, the first breathable membrane 2142 is located above the silica gel part 2143, and the first upper cover 2141 covers the first air cavity 213.

[0043] A first air chamber 213 is provided with a first air intake structure 214, which includes a first upper cover 2141, a first breathable membrane 2142, and a silicone part 2143. The silicone part 2143 is located inside the air chamber, the first breathable membrane 2142 is located above the silicone part 2143, and the first upper cover 2141 covers the first air chamber 213. The first breathable membrane 2142 can allow gas to pass through, but does not allow liquid, dust, bacteria, etc. to pass through. In this way, the gas can escape from the first air chamber 213, while external liquid, dust, and bacteria cannot enter, thus keeping the gas in the first air chamber 213 unobstructed and preventing external dust from contaminating the liquid medicine. When there is a negative pressure inside the medicine bottle (i.e., the pressure inside the bottle is small), the silicone part 2143 can deform inward, allowing air to enter the medicine bottle and balancing the pressure difference inside and outside the bottle, avoiding the situation where the liquid medicine cannot flow out smoothly or generates resistance due to excessive negative pressure. When there is a positive pressure inside the medicine bottle (i.e., the pressure inside the bottle is large), the silicone part 2143 can deform outward, preventing the liquid medicine from leaking from the bottle mouth or around the silicone part 2143 by compression or sealing. The first upper cover 2141 is located above the second air chamber 313, and its function is to fix the second air chamber 313, thereby fixing the components inside the first air chamber 213, such as the first breathable membrane 2142 and the silicone part 2143, etc. This can prevent the first breathable membrane 2142 and the silicone part 2143 from falling off from the first air chamber 213. In this embodiment, by setting the first air intake structure 214, including the first upper cover 2141, the first breathable membrane 2142, and the silicone part 2143, the air permeability, protection, and sealing of the first air chamber 213 can be achieved, and external pollutants can be prevented from entering, thus maintaining the purity and stability of the gas.

[0044] In some embodiments, the air intake structure further includes a silicone fixing cover 2144, which is disposed inside the air chamber and is tightly connected to the outer peripheral side of the silicone part 2143.

[0045] The air intake structure further includes a silicone fixing cover 2144, which is disposed inside the air chamber and is tightly connected to the outer peripheral side of the silicone part 2143. The function of the silicone fixing cover 2144 is to fix the silicone part 2143 and maintain its stability. By tightly connecting to the outer peripheral side of the silicone part 2143, the silicone fixing cover 2144 can ensure the accuracy and stability of the position of the silicone part 2143 inside the air chamber. This can effectively prevent the silicone part 2143 from loosening or shifting during use, ensuring the normal function of the air intake structure. In addition, the silicone fixing cover 2144 can also increase the sealing performance of the air intake structure. By tightly connecting to the outer periphery of the silicone part 2143, the silicone fixing cover 2144 can reduce or prevent gas or liquid from passing through the gap between the silicone part 2143 and the air chamber, thereby improving the sealing performance of the air intake structure.

[0046] In some embodiments, the second bottle piercing device 30 includes a second needle 31. The second needle 31 includes a second infusion channel 312. One end of the second infusion channel 312 is connected to the medicine bottle, and the other end is connected to the infusion tube 10. The second bottle piercing device 30 includes the second needle 31, and the second needle 31 includes the second infusion channel 312. One end of the second infusion channel 312 is connected to the infusion tube 10, and the other end is connected to the medicine bottle. With such an arrangement, the liquid medicine can flow from the infusion into the second infusion channel 312 of the second needle 31, enter the medicine bottle through the second bottle piercing device 30, and then be delivered to the position where the liquid medicine needs to be injected. It can ensure the accurate delivery and control of the liquid medicine.

[0047] In some embodiments, a second air inlet channel 311 is further formed in the second needle 31. The second air inlet channel 311 and the second infusion channel 312 are arranged separately from each other; a second air cavity 313 is formed in the needle, and the second air cavity 313 is communicated with the second air inlet channel 311.

[0048] The second air inlet channel 311 and the second infusion channel 312 are arranged separately from each other, which can effectively prevent air, air bubbles or other contaminants from entering the liquid medicine, ensuring the purity and safety of the liquid medicine. Through the second air inlet channel 311, air or gas can be introduced into the needle. In this way, when needed, the pressure balance of the liquid medicine can be adjusted to avoid affecting the flow of the liquid medicine due to excessive negative pressure or positive pressure generated inside the medicine bottle. The second air cavity 313 formed in the needle is communicated with the second air inlet channel 311. In this way, it can be ensured that the air or gas entering the needle can smoothly enter the second air cavity 313 without directly contacting the liquid medicine. This can avoid the generation of air bubbles and ensure the quality and effect of the liquid medicine. With such an arrangement, the purity and safety of the liquid medicine can be ensured, and an air inlet channel is provided to adjust the pressure balance of the liquid medicine.

[0049] In some embodiments, a second air inlet structure 314 is arranged in the second air cavity 313. The second air inlet structure 314 includes a second upper cover 3141 and a second breathable membrane 3142; the first breathable membrane 2142 is located in the second air cavity 313, and the first upper cover 2141 is covered on the second air cavity 313.

[0050] The second breathable membrane 3142 can allow gases to pass through, while not allowing liquids, dust, bacteria, etc. to pass through. In this way, gases can escape from the second air chamber 313, while external liquids, dust, and bacteria cannot enter, thereby keeping the gases in the second air chamber 313 unobstructed and preventing external dust from contaminating the liquid medicine. The second upper cover 3141 is located above the second air chamber 313, and its function is to fix the second air chamber 313, thereby fixing the components in the second air chamber 313, such as the second breathable membrane 3142, etc. This can prevent the second breathable membrane 3142, etc. from falling off from the second air chamber 313. In this embodiment, by providing the second air inlet structure 314, including the second upper cover 3141 and the second breathable membrane 3142, the breathability, protection, and sealing of the second air chamber 313 can be achieved, and external pollutants can be prevented from entering, thereby maintaining the purity and stability of the gases.
