Due to their rapid onset of action, accurate dosage, and suitability for patients who cannot take oral medication, injectable drugs occupy an important position in clinical treatment.

[0003] Currently, human injectable drugs are all produced using biopharmaceutical solution preparation systems. However, existing biopharmaceutical solution preparation systems use high pressure to inject the solution into the mixing vessel. After the high-pressure solution enters the mixing vessel, it will be mixed. This mixing method may result in insufficient mixing. In addition, existing mixing vessels are all integral units. During cleaning, high-pressure water is used to rinse the inner wall of the mixing vessel. After rinsing, the inside of the mixing vessel is not easy to dry. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] according to Figure 1 As shown in Figure 4: This utility model provides a liquid preparation and cleaning device, including a mixing vessel; the mixing vessel is provided with a mixing mechanism 1, the mixing vessel is composed of a cover plate 2, several interlocking arc-shaped side plates 3, and a base 4, the upper and lower ends of the side plates 3 are respectively threaded to the cover plate 2 and the base 4, and the cover plate 2, side plates 3, and base 4 are provided with a fixing mechanism 5; by setting the mixing mechanism 1 on the mixing vessel, various solutions can be stirred after entering the mixing vessel, so as to achieve uniform mixing; by setting the mixing vessel to be threaded, the device can be disassembled, and the disassembled device is easy to clean and dry; by setting the fixing mechanism 5, the device can be fixed again after installation.

[0023] according to Figure 1 , 2 As shown: The mixing mechanism 1 includes a rotary telescopic motor 101 mounted on the cover plate 2 with its output shaft passing through the cover plate 2, and several stirring rods 102 mounted on the output shaft of the rotary telescopic motor 101; the uppermost stirring rod 102 does not contact the cover plate 2 when it is at its highest point; thus, by starting the rotary telescopic motor 101, the stirring rods 102 can be driven to rotate, and when the solution enters the mixing vessel, it can be driven by the stirring rods 102, thereby achieving uniform mixing;

[0024] according to Figure 1 , 2 As shown in Figures 3 and 4: The lower end of the cover plate 2 is provided with an upper internal thread 201; the cover plate 2 is provided with handle 1 202 on both sides of the rotary telescopic motor 101, and liquid inlet pipes 203 connecting to the solution are provided at both ends of the rotary telescopic motor 101; the upper and lower ends of the side plate 3 are provided with upper external threads 301 and lower external threads 302 respectively; one side is provided with a platform 303, and the other side is provided with a slot 304 corresponding to the platform 303; a handle 2 305 is provided in the middle of the outer side; the upper end of the base 4 is provided with a lower internal thread 401, and the lower middle part is provided with a handle 305. The system is equipped with a drain pipe 402 and four support legs 403 at the bottom corners. A valve 404 is installed on the drain pipe 402. By inserting the insertion platform 303 into the slot 304, several side plates 3 can be connected together. Then, the lower external threads 302 of several side plates 3 are connected to the lower internal threads 401 to install several side plates 3 onto the base 4. Next, the upper internal threads 201 are connected to the upper external threads 301 of several side plates 3 to install the cover plate 2 onto several side plates 3, thereby completing the installation of the mixing vessel.

[0025] according to Figure 1 , 3As shown: The fixing mechanism 5 includes mounting platforms 501 located on the upper and lower parts of the outer side of the side plate 3, with openings facing upwards and downwards respectively. A lead screw 502, with one end rotatably mounted in the mounting platform 501 via a connecting pin, and a nut 503 threaded onto the lead screw 502. When the upper and lower lead screws 502 are in a vertical state, their upper and lower ends extend beyond the cover plate 2 and the base 4 respectively, and the outer edge of the nut 503 is located inside the cover plate 2 and the base 4. Thus, after the mixing vessel is installed, rotating the lead screw 502 so that the upper lead screw 502 is in a vertical state with its upper end above the cover plate 2 and the lower lead screw 502 is in a vertical state with its lower end below the base 4, and then screwing the nut 503 into the lead screw 502, so that the lower end of the upper nut 502 contacts the cover plate 2 and the upper end of the lower nut 502 contacts the base 4, can fix the mixing vessel again.

[0026] Among them, the part where the cover plate 2 connects to the base 4 and the part where several side plates 3 are connected to each other are provided with sealing strips; in this way, various solutions will not leak when the device is in use.

[0027] The principle of this utility model is as follows: In use, different solutions are first quantitatively introduced into the mixing vessel through the inlet pipe 203. Then, the rotary telescopic motor 101 is started, which drives the stirring rod 102 to rotate, so that the solutions are uniformly mixed. After the solutions are mixed, the valve 404 is opened, and the mixed solutions are discharged through the drain pipe 402.

[0028] When it is necessary to clean the inside of the mixing vessel, first unscrew the nut 503, then rotate the cover plate 2, remove the cover plate 2 from the side plates 3, then rotate the side plates 3, remove the side plates 3 from the base 4, and finally separate the side plates 3. In this way, the device is disassembled. The disassembled device can be cleaned conveniently and quickly, and can also be dried quickly after cleaning.

[0029] After cleaning, first insert the insertion platform 303 into the slot 304 to connect several side plates 3 together. Then connect the lower external threads 302 of several side plates 3 to the lower internal threads 401 to install several side plates 3 onto the base 4. Next, connect the upper internal threads 201 to the upper external threads 301 of several side plates 3 to install the cover plate 2 onto several side plates 3, thus completing the installation of the mixing vessel. Finally, rotate the lead screw 502 so that the upper lead screw 502 is in a vertical state with its upper end above the cover plate 2 and the lower lead screw 502 is in a vertical state with its lower end below the base 4. Then screw the nut 503 into the lead screw 502 so that the lower end of the upper nut 502 contacts the cover plate 2 and the upper end of the lower nut 502 contacts the base 4. In this way, the mixing vessel is fixed again. With the help of the sealing strip, the device will not leak.
