[0024] A multi-channel infusion device 100 includes a connecting main pipe 10, a stopcock valve 20, a regulating valve 30, a regulating disc 31, a valve body 32, a liquid passage hole 321, a regulating column 33, a semi-circular groove 331, and a connecting plate 40. Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to specific implementation schemes. However, those skilled in the art should understand that the implementation schemes described below are only for illustrating this utility model and should not be regarded as limiting the scope of this utility model. Based on the implementation schemes in this utility model, all other implementation schemes obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-5 As shown, the multi-channel infusion device 100 according to an embodiment of the present invention includes a connecting main pipe 10, a plurality of stopcock valves 20 and a regulating valve 30.

[0027] Multiple stopcocks 20 are arranged sequentially at the inlet end of the connecting main pipe 10, and the multiple stopcocks 20 are used to connect multiple infusion containers (not shown); the regulating valve 30 is located at the outlet end of the connecting main pipe 10.

[0028] According to the multi-channel infusion device 100 of this utility model, multiple stopcocks 20 are provided at the infusion end of the connecting main pipe 10. The multiple stopcocks 20 can be used for the infusion process of different drugs. At the same time, the regulating valve 30 can accurately adjust the flow rate of the connecting main pipe 10 at any time.

[0029] Preferably, the multi-channel infusion device 100 of this utility model can be equipped with 2, 3, or 4 more stopcocks 20 on the connecting main pipe 10, so that different connecting main pipes 10 can be selected according to the patient's condition.

[0030] In some embodiments, there are multiple main connection pipes 10, which are connected in series, and each main connection pipe 10 can be equipped with multiple plug valves 20.

[0031] Therefore, the number of plug valves 20 can be further increased.

[0032] In some embodiments, such as Figure 1As shown, the multi-channel infusion device 100 also includes a connecting plate 40, one side of which is connected to the main body of a plurality of stopcock valves 20. The connecting plate 40 can prevent the plurality of stopcock valves 20 from colliding.

[0033] It is understandable that when the connecting main pipe 10 is a flexible hose, and multiple stopcocks 20 are installed on the connecting main pipe 10, the stopcocks 20 may collide or be squeezed together, which could easily cause harm to the patient. In this utility model, by providing a connecting plate 40, the connecting plate 40 effectively defines the spatial position of the multiple stopcocks 20, which helps to prevent the multiple stopcocks 20 from colliding.

[0034] In some embodiments, such as Figure 1 As shown, a transparent bag (not shown) is provided on the connecting plate 40 at the position corresponding to the stopcock valve 20. A sticker can be placed inside the transparent bag, and the sticker is used to record infusion information.

[0035] Understandably, the design of the transparent bags and stickers improves the convenience of medical staff's work.

[0036] In some embodiments, such as Figure 1 As shown, the plug valve 20 is a three-way plug valve.

[0037] In some embodiments, such as Figures 2-4 As shown, the regulating valve 30 includes a regulating disc 31 and a valve body 32. The valve body 32 is cylindrical, and two liquid passage holes 321 are symmetrically arranged on the inner wall of the valve body 32. The valve body 32 is connected in series to the liquid outlet end of the connecting main pipe, and the two liquid passage holes 321 are used for liquid flow. A regulating column 33 is provided at the lower part of the regulating disc 31. The regulating column 33 passes through the valve body 32. The lower end of the regulating column 33 is used to seal the lower opening of the valve body 32, and the regulating disc 31 is used to seal the upper opening of the valve body 32. A semi-circular groove 331 is provided on the regulating column 33. During the rotation of the regulating column 33, when the two ends of the semi-circular groove 331 are connected to the two liquid passage holes 321 respectively, the regulating valve 30 is at its maximum flow rate.

[0038] Understandably, the design of the regulating disc 31 improves the control precision and convenience for medical staff when adjusting the flow rate.

[0039] In some embodiments, there is a gap between the middle position of the adjusting column 33 and the inner wall of the valve body 32. During the rotation of the adjusting column 33, when the semi-circular groove 331 is connected to one liquid passage hole 321 and disconnected from the other liquid passage hole 321, the gap is used for liquid flow.

[0040] In some embodiments, such as Figure 1 As shown, a scale bar (not shown) is provided on the surface of the adjustment disc 31. Preferably, the scale bar is an arc-shaped bar.

[0041] Understandably, the design of the scale bar helps medical staff to more accurately adjust the flow rate.

[0042] In some embodiments, such as Figure 1 As shown, the outer periphery of the adjustment disc 31 is provided with a toothed edge.

[0043] Understandably, the toothed edge design helps medical staff rotate the adjustment disc 31 more stably.
