It should be particularly emphasized that a method for using a filling device for drug production includes the following steps: Step 1: Place the empty bottles on the bottle conveying device, start the control system of the bottle conveying device and the filling equipment, the bottle conveying device transports the empty bottles to the filling position in sequence, at this time the first lifting hydraulic rod cone body 31 cone body drives the filling head cone body 332 cone body to descend, and the filling head cone body 332 cone body opens.

[0032] Step 2: The medicine in the filling unit cone body 3 and the liquid storage barrel cone body 2 is extracted by the filling unit cone body 3 and transported to the filling head cone body 335 for filling.

[0033] Step 3: After the filling is completed, the filling unit cone body 3 stops extracting and conveying the medicine, and the first lifting hydraulic rod cone body 31 drives the filling head cone body 332 to rise, and the filling head cone body 332 is automatically closed.

[0034] Cleaning and disinfection: Before using the equipment, it is necessary to thoroughly clean and disinfect it. First, remove the easily removable parts of the filling unit 3 and clean them with a special cleaning agent. For the liquid storage tank 2, thoroughly clean the inside to remove residual drugs and impurities. Then, sterilize the equipment by high-temperature steam sterilization or chemical disinfectant sterilization. For example, hydrogen peroxide vapor can be used to sterilize the equipment, which can effectively kill bacteria, viruses and spores without leaving harmful residues on the equipment.

[0035] Equipment debugging: After cleaning and disinfection, the equipment needs to be debugged. Check the operation of the peristaltic pump 33, start the peristaltic pump 33, and observe whether the drug is transported normally in the infusion hose 331. At the same time, check whether the valve of the filling head 335 opens and closes flexibly, and adjust the position of the filling head 335 so that it can accurately align with the bottle body.

[0036] Start the device: Place the empty bottle on the bottle conveying device, and start the control system of the bottle conveying device and the filling device. The bottle conveying device sequentially conveys the empty bottle to the filling position, and at the same time, the medicine in the liquid storage barrel 2 is conveyed to the filling head 335 through the shunt pipe 211, the infusion hose 331 and the filling head 335.

[0037] Filling process control: During the filling process, control the opening and closing of the movable tube valve 335 and the speed of the peristaltic pump 33. During the filling process, pay attention to the operation of the equipment and check whether there is drug leakage or abnormal bottle dumping. If any abnormality is found, stop the equipment operation in time for inspection and treatment.

[0038] Equipment cleaning: After the filling task is completed, the equipment should be cleaned in time. First, stop the delivery of the medicine and clean the remaining medicine in the shunt tube 211, the infusion hose 331 and the filling head 335. It can be rinsed with clean water. For the liquid storage barrel 2, the remaining medicine should be discharged and then cleaned. After cleaning, all parts of the equipment should be wiped dry to prevent rust.

[0039] Equipment maintenance: Maintain the equipment regularly and check whether the various parts of the equipment are worn or aged.

[0040] For example, check whether the seal of the peristaltic pump 33 is intact, whether the pipeline has cracks, and whether the valve of the filling head 335 is flexible. For vulnerable parts, such as seals and rubber tubes, they should be replaced regularly to ensure the normal operation of the equipment.

[0041] Working principle: First, inject the liquid medicine to be filled into the liquid storage barrel 2. The liquid storage barrel 2 is provided with a stirrer 24. Start the stirrer 24 to continuously stir the liquid medicine in the liquid storage barrel 2 to prevent the liquid medicine from settling and causing uneven distribution of the liquid medicine components. The liquid level monitor 23 detects the liquid level. When the liquid level reaches the set height, the liquid level monitor 23 issues a warning and stops injecting the liquid medicine into the liquid storage barrel 2. Then, the second lifting hydraulic rod 34 is started, driving the clamping plate 341 to move and adjust the clamping plate so that the clamping plate 341 is in close contact with the container mouth and does not touch the container mouth. The first lifting hydraulic rod 31 is started, driving the lifting arm 32 to drive the filling head 332 to move downward, so that the filling head 332 passes through the circular hole opened in the clamping plate 341. At this time, the movable pipe valve 335 provided with the baffle 336 is linked with the clamping plate 341 and moves upward. At this time, the valve of the filling head 332 is opened and inserted into the container. Finally, the peristaltic pump 33 is started to extract the medicine liquid in the liquid storage barrel 2 according to the preset amount, and inject it into the container through the infusion hose 331 and the filling head 332. After the filling is completed, the peristaltic pump 33 stops working, and then the first lifting hydraulic rod 31 drives the filling head 332 to rise, so that the filling head 332 is separated from the container. At this time, the movable pipe valve 335 moves downward under the action of the spring 337, so that the filling head 332 is closed to prevent the residual medicine liquid in the filling head 332 from dripping. When the liquid level in the liquid storage barrel 2 is too low during the filling process, in order to ensure continuous and stable filling, the liquid level monitor 23 will sound an alarm to inform the staff to add medicine liquid to the liquid storage barrel 2.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
