Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a connecting valve and a contrast agent filling machine. Background Art

[0002] The contrast agent filling machine usually includes a liquid medicine storage tank, a medicine bottle and a connecting pipe. When the liquid medicine in the medicine bottle is injected, the liquid medicine in the liquid medicine storage tank can enter the medicine bottle through the connecting pipe, thereby delivering the liquid medicine to the medicine bottle, increasing the liquid medicine content in the medicine bottle, and preventing the medicine bottle from having no liquid medicine for injection. Therefore, the injection of liquid medicine can continue without changing the medicine bottle.

[0003] However, in the current contrast agent filling machines, if the liquid medicine content in the medicine bottle is high, if the liquid medicine is still delivered to the medicine bottle at a large flow rate, it will cause the liquid medicine pressure in the medicine bottle to increase, thereby increasing the injection speed, which may cause harm to the patient.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Combine the following Figure 1 , the connecting valve 100 and the contrast agent filling machine provided in the embodiment of the present application are described in detail through specific embodiments.

[0032] Please also read Figure 1 The connecting valve 100 provided in one embodiment of the utility model comprises a delivery pipe 10, a one-way valve 20, a first connecting pipe 30 and a second connecting pipe 40. The one-way valve 20 is arranged on the delivery pipe 10; one end of the first connecting pipe 30 is connected to the delivery pipe 10, and the other end is connected to the liquid medicine storage tank; one end of the second connecting pipe 40 is connected to the delivery pipe 10, and the other end is connected to the medicine bottle; wherein the opening of the one-way valve 20 is arranged toward the second connecting pipe 40.

[0033] By setting the one-way valve 20, the flow rate of the fluid in the delivery pipeline 10 can be controlled. The one-way valve 20 allows the fluid to flow freely in a certain direction, but will close when it flows in the reverse direction, thereby limiting the flow rate or preventing backflow. And because the opening of the one-way valve 20 is toward the second connecting pipe 40, when the fluid flows from the delivery pipeline 10 to the medicine bottle, the one-way valve 20 opens, allowing the medicine liquid to flow into the medicine bottle. When the medicine liquid flows back, the one-way valve 20 closes to prevent excess medicine liquid from entering the medicine bottle, thereby ensuring accurate filling of the medicine liquid and avoiding waste. Through such a setting, the setting of the connecting valve 100 can effectively control the flow rate and prevent excess medicine liquid from entering the medicine bottle, thereby improving the filling accuracy and efficiency of the contrast agent filling machine.

[0034] Among them, regarding the one-way valve 20 mentioned above, the one-way valve 20 is a valve, also known as a non-return valve, which is mainly used to control the flow direction of the fluid. It allows the fluid to flow freely in one direction, but blocks or restricts the flow in the opposite direction. In the contrast agent filling machine, the one-way valve 20 is usually designed to be open or closed to achieve specific functions, such as controlling the flow rate and preventing excessive liquid medicine from entering the medicine bottle.

[0035] In the contrast agent filling machine, the structure of the one-way valve 20 generally includes a valve core (or valve cover) and a spring. The valve core (or valve cover) is a core component for controlling fluid flow. When the direction of fluid flow is consistent with the direction designed by the one-way valve 20, the valve core allows the fluid to pass; when the fluid attempts to flow back, the valve core is closed to prevent backflow. The spring is used to provide the force to close the valve core. This allows the one-way valve 20 to be closed at a specific pressure to prevent backflow. When the contrast agent needs to flow from the delivery pipeline 10 to the medicine bottle, the one-way valve 20 will open to allow the contrast agent to flow into the medicine bottle. In this case, the one-way valve 20 allows the fluid to flow freely in a predetermined direction. When the contrast agent filling is completed or backflow needs to be prevented, the one-way valve 20 will be closed. This prevents excessive liquid medicine from flowing back into the delivery pipeline 10, thereby ensuring accurate filling of the liquid medicine and avoiding waste.

[0036] In some embodiments, a connecting piece 50 is further included. The connecting piece 50 is disposed between the first connecting pipe 30 and the delivery pipeline 10 . The connecting piece 50 is used to connect the first connecting pipe 30 and the delivery pipeline 10 .

[0037] The connector 50 can connect the first connecting pipe 30 and the delivery pipe 10. When the liquid medicine in the liquid medicine storage tank is delivered, the liquid medicine enters the connector 50 through the first connecting pipe 30, and enters the delivery pipe 10 through the connector 50, thereby delivering the liquid medicine to the medicine bottle through the delivery pipe 10.

[0038] In some embodiments, a rotating member 60 is further included. The rotating member 60 is disposed on a side of the delivery pipeline 10 close to the first connecting pipe 30 , and the rotating member 60 is rotatably connected to the connecting member 50 .

[0039] By the rotational connection between the rotating member 60 and the connecting member 50 , the first connecting pipe 30 is connected to the rotating member 60 , so that the first connecting pipe 30 can be rotated to change the angle to adapt to the liquid medicine storage tanks at different positions.

[0040] In some embodiments, the connecting member 50 is provided with a receiving channel, and the rotating member 60 is received in the receiving channel. The rotating member 60 also includes a connecting rod, and first through holes are provided on both sides of the receiving channel. The connecting member 50 is provided with a second through hole, and the position of the first through hole corresponds to the position of the second through hole. The connecting rod is passed through the first through hole and the second through hole, so that the rotating member 60 and the connecting member 50 are rotatably connected.

[0041] By providing an accommodating channel on the connecting member 50 and accommodating the rotating member 60 in the accommodating channel, the rotating member 60 can rotate around the connecting member 50 in the accommodating channel, so that the rotating member 60 drives the first infusion pipeline to rotate and change the angle.

[0042] Specifically, a first through hole is opened on both sides of the accommodating channel, a second through hole is opened on the rotating member 60, and a connecting rod is passed through the first through hole and the second through hole, so that the rotating member 60 and the connecting member 50 are connected to each other, and the rotating member 60 can rotate around the connecting rod to realize the rotation of the rotating member 60 in the accommodating channel.

[0043] In some embodiments, the device further comprises a shell, which is covered on the infusion pipeline. By arranging the shell on the infusion pipeline, the infusion pipeline can be effectively protected to prevent the infusion pipeline from being damaged due to collision.

[0044] In some embodiments, a mounting hole is provided on the housing, and the one-way valve 20 is disposed on the infusion pipeline through the mounting hole. The position of the mounting hole corresponds to the position where the one-way valve 20 is installed on the infusion pipeline, so that the one-way valve 20 can be installed on the infusion pipeline while the infusion pipeline is protected by the housing.

[0045] In some embodiments, multiple infusion pipelines may be provided, and both ends of the multiple infusion pipelines are connected to a first connecting tube 30 and a second connecting tube 40; wherein each first connecting tube 30 can be connected to a different drug liquid storage tank, and each second connecting tube 40 can be connected to a different medicine bottle.

[0046] Among them, by providing multiple infusion pipelines, multiple drug storage tanks and medicine bottles are also provided, so that different drug liquids can be respectively transported to different medicine bottles for injection.

[0047] Another embodiment of the utility model provides a contrast agent filling machine, including the above-mentioned connecting valve 100, a liquid medicine storage tank and a medicine bottle. The liquid medicine storage tank is connected to the first connecting pipe 30 of the connecting valve 100; the medicine bottle is connected to the second connecting pipe 40 of the connecting valve 100. Through the setting of the one-way valve 20, the flow rate control of the fluid in the conveying pipeline 10 can be achieved. The one-way valve 20 allows the fluid to flow freely in a certain direction, but will close when it flows in the reverse direction, thereby limiting the flow rate or preventing the reverse flow. And because the opening of the one-way valve 20 is facing the second connecting pipe 40, when the fluid flows from the conveying pipeline 10 to the medicine bottle, the one-way valve 20 opens, allowing the liquid medicine to flow into the medicine bottle. When the liquid medicine flows in reverse, the one-way valve 20 is closed to prevent excessive liquid medicine from entering the medicine bottle, thereby ensuring accurate filling of the liquid medicine and avoiding waste. Through such a setting, the setting of the connecting valve 100 can effectively control the flow rate, prevent excessive liquid medicine from entering the medicine bottle, and improve the filling accuracy and efficiency of the contrast agent filling machine.
