[0002] Reganoxone injection is a selective A2A adenosine receptor agonist primarily used to aid in the diagnosis of myocardial ischemia and is suitable for patients who cannot undergo exercise stress testing.

[0024] Example 1: An extraction mechanism for preparing Reganoxan injection, such as... Figures 1-4As shown, the system includes a mixing tank 1, which is equipped with a stirring mechanism and a circulation mechanism. The stirring mechanism includes a stirring assembly 3, which includes a support 35. The support 35 is fixedly installed on the side of the mixing tank 1. A vertical plate 310 is fixedly installed on the top of the support 35. A first motor 36 is fixedly installed on the side of the vertical plate 310. The shaft end of the first motor 36 passes through the vertical plate 310 and is fixedly installed on a turntable 37. A slide rod 34 is fixedly installed on the turntable 37. A limit plate 311 is fixedly installed on the side of the vertical plate 310. A lifting rod 33 slides through the limit plate 311. A track 38 is fixedly installed on the top of the lifting rod 33. The slide rod 34 slides in the track 38. An installation plate 312 is fixedly installed on the bottom of the lifting rod 33.

[0025] The circulation mechanism includes a circulation component 2, which includes a receiving plate 22. The receiving plate 22 is fixedly installed on the surface of the mixing tank 1. A pump body 23 is fixedly installed on the top of the receiving plate 22. A first conduit 21 and a second conduit 25 are fixedly installed on the surface of the mixing tank 1. Valves are fixedly installed on both the first conduit 21 and the second conduit 25.

[0026] The bottom end of the mounting plate 312 is rotatably connected to a first pipe 315. The top end of the first pipe 315 is closed, and the bottom end of the first pipe 315 is open. The inner wall of the first pipe 315 is rotatably connected to a second pipe 39.

[0027] A connecting rod 313 is fixedly connected to the inner wall of the first pipe 315. The connecting rod 313 is cylindrical. A first stirring rod 32 is fixedly installed at the bottom end of the connecting rod 313. The first stirring rod 32 is square. A second stirring rod 31 is fixedly installed on the surface of the second pipe 39. The second stirring rod 31 is square.

[0028] A first gear ring 316 is fixedly installed on the first pipe 315, a second gear ring 314 is fixedly installed on the second pipe 39, a mounting base 317 is fixedly installed at the bottom end of the mounting plate 312, a second motor 318 is fixedly installed on the surface of the mounting base 317, and a gear 319 is fixedly installed at the shaft end of the second motor 318. The gear 319 meshes with the first gear ring 316 and the second gear ring 314.

[0029] A transparent glass 4 is fixedly installed on the surface of the mixing box 1. The transparent glass 4 is square in shape and penetrates the inner wall of the mixing box 1.

[0030] In use, the raw material solution containing Reganoxant and the extraction solvent are added into the mixing tank 1. Then, the first motor 36 and the second motor 318 are started. The second motor 318 drives the gear 319 to rotate. The gear 319 meshes with the first gear ring 316 and the second gear ring 314, which simultaneously drives the first pipe 315 and the second pipe 39 to rotate in opposite directions. When the first pipe 315 and the second pipe 39 rotate, they drive the first stirring rod 32 and the second stirring rod 31 to rotate in opposite directions. At the same time, the first motor 36 drives the turntable 37 to rotate. The turntable 37 drives the slide rod 34 to perform circular motion. During the movement, the slide rod 34 drives the lifting rod 33 along the track 38. The through hole of 311 moves vertically back and forth. When the lifting rod 33 moves vertically back and forth, it will drive the first stirring rod 32 and the second stirring rod 31 to move vertically back and forth through the mounting plate 312, the first pipe 315 and the second pipe 39. Through the above settings, the molecular diffusion between the solution to be separated and the extraction solution can be accelerated, so that the two can reach a more uniform mixing state in a short time, thereby improving the rate and efficiency of the extraction process. At the same time, stirring helps to ensure that the extraction solution is evenly distributed in the entire solution to be separated, avoiding local concentrations that are too high or too low. This helps to achieve a more consistent extraction effect and reduce batch-to-batch differences. After stirring is completed, stirring is stopped and the mixture is allowed to stand for a period of time to allow the two phases to naturally separate, thereby achieving the purpose of extraction. Furthermore, the transparent glass 4 facilitates the observation of the extraction of the solution.

Figures 1-4 As shown, one end of the first conduit 21 is fixedly connected to the inlet pipe of the pump body 23, and one end of the second conduit 25 is fixedly connected to the outlet pipe of the pump body 23.

[0033] During the stirring process, the pump body 23 is started. The pump body 23 draws the solution in the mixing tank 1 through the first conduit 21 and discharges it back into the mixing tank 1 through the second conduit 25. The above settings help to accelerate the molecular diffusion between the solution to be separated and the extraction solution, so that the two can reach a more uniform mixing state in a short time. Furthermore, with the third conduit 24, when it is necessary to remove the solution, the valve at the second conduit 25 is closed and the valve at the third conduit 24 is opened, and then the pump body 23 is started again to draw the solution out of the mixing tank 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
