[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example: Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, this utility model discloses a multi-channel liquid dispenser for preparing medicine solutions, comprising a base plate 1, with vertically upward support rods 2 at each corner of the base plate 1, a top plate 3 at the top of the multiple support rods 2, and movable plates 4 slidably connected to the multiple support rods 2. Multiple medicine-containing measuring cylinders 5 are equidistantly arranged on the movable plate 4, a medicine storage bottle 6 is located in the middle of the top plate 3, and a multi-channel distribution pipe 7 connected to the multiple medicine-containing measuring cylinders 5 is located at the bottom of the medicine storage bottle 6. A piston is located inside the medicine storage bottle 6, and a push rod extending from the top of the piston is located at the top of the medicine storage bottle 6. The multi-channel distribution pipe 7 includes a first connector 8 located at both ends of the medicine-containing measuring cylinders 5 and a second connector 9 located at the bottom of the medicine storage bottle 6. A multi-port pipe 10 is sleeved on the outside of the second connector 9, and multiple outlet branches of the multi-port pipe 10 are connected to... The multi-port pipe 10 is connected to multiple first connectors 8 via flexible hoses 11. Each of the multiple outlet branches of the multi-port pipe 10 is equipped with a first control valve 12. The bottom end of the liquid-holding cylinder 5 is connected to a needle 23 via the first connector 8. A second control valve is installed on the first connector 8 at the bottom end of the liquid-holding cylinder 5. The top end of the liquid-holding cylinder 5 is provided with a vent hole, and a dust filter is installed inside the vent hole. The dust filter is made of nanofiber, which can both allow air to pass through and prevent the liquid from being contaminated. When the first control valve 12 is opened, the push rod is pushed so that the piston pushes the liquid through the multi-port pipe 10 and multiple flexible hoses 11 into the multiple liquid-holding cylinders 5. When the amount of liquid in the liquid-holding cylinder 5 reaches the required amount, the second control valve is opened so that the liquid inside the liquid-holding cylinder 5 can be added to the medicine bottle to be prepared through the needle 23.

[0028] Specifically, such as Figure 5 As shown, the outer wall of the measuring cylinder 5 for holding the medicine liquid is engraved with scale markings 13, which can accurately prepare the medicine liquid and determine the amount of medicine liquid to be dispensed.

[0029] Specifically, such as Figure 1 As shown, both ends of the base plate 1 are equipped with vertically upward electric push rods 14. The output shaft of the electric push rods 14 is connected to the movable plate 4. Guide holes for the support rods 2 to pass through are provided at the corners of the movable plate 4, which allows the movable plate 4 to rise and fall. When it falls, the needles 23 of multiple liquid-filled measuring cylinders 5 can be inserted into the medicine bottles to be prepared at the same time, which indirectly improves the efficiency of medicine preparation.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the top of the top plate 3 is provided with a fixing bracket 15 for fixing the medicine storage bottle 6. The fixing bracket 15 includes a positioning post 16 located in the middle of the top plate 3. The top of the positioning post 16 is provided with a positioning groove 17. Two branch pipe slots 18 connected to the positioning groove 17 are symmetrically provided on the positioning post 16. The positioning groove 17 can quickly position the medicine storage bottle 6.

[0031] The top plate 3 has multiple through holes 19 for the flexible hose 11 to pass through.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the movable plate 4 is provided with a fixing assembly for fixing multiple liquid-filled measuring cylinders 5. The fixing assembly includes multiple positioning holes 20 on the movable plate 4. The bottom end of the movable plate 4 is provided with a positioning support tube 21 located at the positioning hole 20. The front of the movable plate 4 is provided with an observation slot 22 communicating with the multiple positioning holes 20. The top of the movable plate 4 is provided with multiple vertically upward uprights 24. The top of the multiple uprights 24 is provided with a horizontal plate 25. The top of the horizontal plate 25 is movably connected to a movable plate. The end of the movable plate is provided with multiple limiting baffles 26 corresponding one-to-one with the positioning holes 20. The horizontal plate 25 is provided with guide rails 27 that match the two ends of the limiting baffles 26. A fixed ring block 28 is provided at the top of the horizontal plate 25. A pull rod 29 is provided inside the fixed ring block 28. A return spring 30 is sleeved on the pull rod 29. One end of the pull rod 29 is connected to the limiting baffle 26. The other end of the pull rod 29 is provided with a pull ring. When fixing the medicine liquid measuring cylinder 5, the pull ring is pulled, and the pull ring drives the pull rod to move. The pull rod drives the limiting baffle 26 to move. Under the guidance of the two guide slide rails 27, the return spring 30 is compressed. When multiple medicine liquid measuring cylinders 5 are respectively placed into the positioning holes 20, the positioning support tube 21 provides limiting support for the medicine liquid measuring cylinders 5. Under the elastic force of the return spring 30, the limiting baffle 26 moves to the top of the medicine liquid measuring cylinder 5 to limit the medicine liquid measuring cylinder 5.

[0033] During operation, the multi-channel distribution pipe 7 allows the liquid medicine inside the medicine storage bottle 6 to be connected to multiple liquid medicine measuring cylinders 5 via the multi-port pipe 10 and multiple hoses 11. This allows the liquid medicine inside the medicine storage bottle 6 to be input into the multiple liquid medicine measuring cylinders 5 via the multi-port pipe 10 and multiple hoses 11. The same liquid medicine can be simultaneously distributed into multiple liquid medicine measuring cylinders 5, reducing the current need for one-by-one preparation steps and improving the efficiency of liquid medicine preparation.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
