This type of liquid medicine filling device usually does not directly connect to a medicine storage tank. Instead, staff first pump the liquid medicine to an independent buffer tank through a water pump, and the buffer tank supplies the liquid medicine directly to the liquid medicine filling device. Since the speed of pumping the liquid medicine by the water pump is higher than the speed of filling the liquid medicine, this liquid medicine replenishment link needs to be intermittent, which requires high experience of personnel. This makes it easy to have insufficient liquid medicine in the buffer tank during the liquid medicine filling process, resulting in the volume of the filled bottles not meeting the specifications, and even air bubbles appearing in the liquid medicine.

Detailed implementation manners

[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Please refer to Figures 1 to 5 , this embodiment provides a liquid medicine filling device, which includes a rotating base 1. A turntable 2 is provided on the rotating base 1. A plurality of syringe injectors 3 arranged in a circumferential pattern are evenly provided on the upper end of the turntable 2. A liquid medicine distribution container 4 that rotates synchronously with the turntable 2 is provided on the turntable 2. A liquid medicine collection container 5 that rotates synchronously with the liquid medicine distribution container 4 is provided directly above the liquid medicine distribution container 4. A liquid inlet main pipe 6 for transporting the liquid medicine is connected between the liquid medicine collection container 5 and the liquid medicine distribution container 4, and a return liquid pipe 7 for recycling the excess liquid medicine to the liquid medicine collection container 5. A plurality of hollow tubes 8 for supporting and connected to the liquid medicine distribution container 4 are provided on the circumferential side of the liquid medicine collection container 5. A monitoring component 9 for facilitating real-time monitoring of the liquid flow rate in the pipe is provided on the liquid inlet main pipe 6.

[0031] In this embodiment, through the settings of the rotating base 1 and the turntable 2, the liquid filling device realizes the automatic rotation of the syringe 3, so as to be able to continuously fill multiple medicine bottles, improving the filling efficiency. The synchronous rotation of the liquid distribution container 4 and the liquid collection container 5 ensures the uniform distribution and recovery of the liquid medicine. The settings of the liquid inlet main pipe 6 and the return liquid pipe 7 realize the automatic transportation and recovery of the liquid medicine. The setting of the monitoring component 9 can monitor the liquid flow in the pipe in real time, ensuring the accuracy of the filling volume. Specifically, in the liquid medicine filling process, generally, a water pump first pumps the liquid medicine from an independent medicine storage tank to an independent buffer tank, and then another water pump pumps the liquid medicine to the filling device, which enters the liquid distribution container 4 along the liquid inlet main pipe 6 and is finally filled in an orderly manner by the syringe 3. During the whole processing process, the buffer tank will intermittently supplement the liquid medicine from the medicine storage tank through the water pump to supply the filling device. If the liquid medicine in the buffer tank is not supplemented in time, it may lead to insufficient liquid medicine in the liquid inlet main pipe 6, and then the liquid medicine filling volume in the medicine bottle does not meet the standard, and even there are bubbles in the filled liquid medicine, which affects the quality. To avoid the above problems, by setting the monitoring component 9 to monitor the liquid flow in the liquid inlet main pipe 6 in real time, the water pump can be turned on and off in time to supplement the liquid medicine in the buffer tank, so as to realize the precise control of the filling volume.

[0032] More specifically, the monitoring component 9 can be a visual pipeline structure for convenient direct visual observation by the staff, or a flow sensor and a controller integrating monitoring and automatic control functions. The flow sensor is used to detect the liquid flow in the liquid inlet main pipe 6 and transmit the signal to the controller. The controller is electrically connected to the water pump and, according to the preset warning value of the liquid medicine flow, timely turns on the water pump to supplement the liquid medicine in the buffer tank, realizing the precise control of the liquid medicine filling volume and ensuring the quality of the liquid medicine production.

[0033] Further, as a preferred implementation manner rather than a limitation of this solution, the monitoring component 9 includes a transparent pipe 91 provided on the liquid inlet main pipe 6. In this embodiment, the monitoring component 9 includes a transparent pipe 91 provided on the liquid inlet main pipe 6. The transparent pipe 91, as a part of the liquid inlet main pipe 6, enables the staff to directly observe the liquid medicine situation in the liquid inlet main pipe 6, so as to monitor in real time whether the liquid medicine is sufficient, and then timely turn on the water pump to supplement the liquid medicine in the buffer tank. The material of the transparent pipe 91 can be glass, preferably borosilicate glass.

[0034] Further, as a preferred implementation manner rather than a limitation of this solution, the liquid inlet main pipe 6 includes a first main pipe 61 passing through the liquid collection container 5 and connected to the upper end of the transparent pipe 91, and a second main pipe 62 communicating with the liquid distribution container 4 and connected to the lower end of the transparent pipe 91.

[0035] In this embodiment, the liquid inlet main pipe 6 includes two parts, a first main pipe 61 and a second main pipe 62. The first main pipe 61 passes through the liquid medicine collection container 5 and is connected to the upper end of the transparent pipe 91, and is used to transport the liquid medicine from the liquid medicine collection container 5 to the transparent pipe 91. The second main pipe 62 communicates with the liquid medicine distribution container 4 and is connected to the lower end of the transparent pipe 91, and is used to transport the liquid medicine from the transparent pipe 91 to the liquid medicine distribution container 4.

[0036] By dividing the liquid inlet main pipe 6 into two parts, the first main pipe 61 and the second main pipe 62, precise control of the liquid medicine flow path can be achieved. Specifically, the settings of the first main pipe 61 and the second main pipe 62 are such that the liquid medicine must pass through the transparent pipe 91 before entering the liquid medicine distribution container 4, so that the staff can directly see the liquid medicine flow rate in the transparent pipe 91 and achieve precise control of the liquid medicine filling volume.

[0037] To ensure the smoothness and stability of the liquid medicine flow, the first main pipe 61 and the second main pipe 62 can be made of the same material and structure, such as stainless steel or PVC, etc. For ease of installation and maintenance, the first main pipe 61 and the second main pipe 62 can be detachably connected, such as by threaded connection or flange connection, etc.

[0038] Further, as a preferred implementation manner rather than a limitation of this solution, a plurality of support columns 63 parallel to the transparent pipe 91 vertically are evenly arranged between the first main pipe 61 and the second main pipe 62.

[0039] In this embodiment, a plurality of support columns 63 parallel to the transparent pipe 91 vertically are evenly arranged between the first main pipe 61 and the second main pipe 62. The setting of the support columns 63 is used to enhance the connection strength between the first main pipe 61 and the second main pipe 62 and provide additional support force to ensure the stability and reliability of the liquid medicine during the flow process.

[0040] Specifically, the support columns 63 can be evenly distributed between the first main pipe 61 and the second main pipe 62 and keep vertically parallel to the transparent pipe 91. This can enable the liquid medicine to receive uniform support force during the flow process and avoid problems such as deformation or even rupture and leakage of the transparent pipe 91 caused by uneven local stress. The material of the support columns 63 can be the same as that of the first main pipe 61 and the second main pipe 62, such as stainless steel or PVC, etc., to ensure the consistency and reliability of the overall structure. For ease of installation and maintenance, the support columns 63 can be detachably connected, such as by threaded connection or snap connection, etc.

[0041] Further, as a preferred implementation manner rather than a limitation of this solution, the monitoring component 9 further includes a flow meter 92 provided on the liquid inlet main pipe 6 for real-time monitoring of the liquid flow rate in the pipe.

[0042] In this embodiment, the monitoring component 9 includes, in addition to the transparent tube 91 provided on the main liquid inlet pipe 6, a flowmeter 92 provided on the main liquid inlet pipe 6 for real-time monitoring of the liquid flow rate in the pipe. The setting of the flowmeter 92 can achieve accurate measurement and control of the liquid medicine flow rate, and further improve the accuracy and efficiency of liquid medicine filling.

[0043] Specifically, the flowmeter 92 is preferably an ultrasonic flowmeter. The ultrasonic flowmeter can be installed at an appropriate position on the main liquid inlet pipe 6, such as on the first main pipe 61 or the second main pipe 62, to ensure that it can accurately measure the liquid medicine flow rate. The ultrasonic flowmeter is connected to the control system of the liquid medicine filling device to real-time monitor the liquid medicine flow rate in the pipe. In addition, an alarm device can be set on the flowmeter 92 to emit an alarm in time when the liquid medicine flow rate is too low, reminding the staff to turn on the water pump in time to supplement the liquid medicine in the buffer tank, so as to achieve accurate control of the liquid medicine filling volume.

[0044] Further, as a preferred implementation manner rather than a limitation of this solution, an installation part 51 corresponding to the hollow tube 8 is provided on the circumferential side of the bottom end of the liquid medicine collection container 5, and a plurality of return port groups 52 corresponding to the hollow tube 8 are provided on the side wall of the liquid medicine collection container 5. The return port groups 52 are used to connect liquid hoses. The liquid hoses pass through the hollow tube 8 and are connected to the injector 3 to recover the excessive liquid medicine during the filling process. The hollow tube 8 includes a docking part 82 corresponding to the installation part 51 at the upper end, and a strip-shaped hole 81 for the liquid hose to pass through is opened at the lower side end of the hollow tube 8.

[0045] In this embodiment, an installation part 51 corresponding to the hollow tube 8 is provided on the circumferential side of the bottom end of the liquid medicine collection container 5 for fixing and supporting the hollow tube 8. A plurality of return port groups 52 corresponding to the hollow tube 8 are provided on the side wall of the liquid medicine collection container 5. The return port groups 52 are used to connect liquid hoses. The liquid hoses pass through the hollow tube 8 and are connected to the injector 3 to recover the excessive liquid medicine during the filling process. The installation part 51 can include structures such as a fixing ring or an installation groove, and the hollow tube 8 is fixed to the bottom end of the liquid medicine collection container 5 through bolts or other fasteners. The return port groups 52 include a plurality of uniformly distributed return ports for connecting with liquid hoses. The liquid hoses can be made of flexible materials such as silicone or PVC to facilitate connection to the injector 3 after passing through the hollow tube 8. By setting the installation part 51 and the return port groups 52, a stable connection between the liquid medicine collection container 5 and the hollow tube 8 can be achieved, and a channel for liquid medicine recovery can be provided.

[0046] Further, a plurality of liquid outlet ends 41 corresponding to the injectors 3 one by one are provided on the liquid medicine distribution container 4, and liquid hoses are connected between the liquid outlet ends 41 and the injectors 3 to meet the liquid medicine supply requirements.

[0047] Further, a first communication part 31 is provided at the upper end of the syringe 3 and is connected to the reflux port group 52 through a liquid hose. A second communication part 32 is connected to the side of the first communication part 31. The second communication part 32 corresponds to the liquid outlet end 41 one by one and is connected through a liquid hose. An injection part 33 for injecting the liquid medicine into the container is provided at the lower end of the syringe 3.

[0048] In this embodiment, a first communication part 31 and a second communication part 32 are provided at the upper end of the syringe 3. The first communication part 31 is connected to the reflux port group 52 on the liquid medicine collection container 5 through a liquid hose and is used to recycle the excessive liquid medicine during the filling process into the liquid medicine collection container 5. The second communication part 32 corresponds to the liquid outlet end 41 on the liquid medicine distribution container 4 one by one and is connected through a liquid hose and is used to receive the liquid medicine supplied by the liquid medicine distribution container 4. An injection part 33 is provided at the lower end of the syringe 3 and is used to inject the liquid medicine into the container.

[0049] Furthermore, an interface 53 connected to the vacuum pipeline is provided at the upper end of the liquid medicine collection container 5.

[0050] The working principle of the present utility model:

[0051] During the liquid medicine filling process, it is very crucial to ensure that the filling volume of each bottle of liquid medicine is consistent. Any deviation may affect the quality of the medicine and the treatment effect of the patient. Therefore, it is particularly important to monitor and control the liquid medicine flow rate in real time.

[0052] The present utility model realizes the precise control of the liquid medicine filling volume by arranging a monitoring component on the existing liquid medicine filling device, ensuring the quality of liquid medicine production. The monitoring component mainly includes a transparent tube and a flow meter. The transparent tube is a part of the main liquid inlet pipe, enabling the staff to directly observe the flow of the liquid medicine. This not only provides visual monitoring but also simplifies the inspection process of the staff, enabling them to discover the change in the liquid medicine flow rate in the first time.

[0053] The flow meter is preferably an ultrasonic flow meter, which can accurately measure the flow rate of the liquid medicine without disturbing the flow of the liquid medicine. The flow meter is connected to the control system and can feedback the liquid medicine flow rate data in real time to ensure the filling accuracy. The flow meter continuously monitors the liquid medicine flow rate in the main liquid inlet pipe and sends the data to the controller. If the monitored flow rate is lower than the preset threshold, the controller will immediately respond and adjust the supply of the liquid medicine by controlling the working state of the water pump. For example, it will be turned on to supplement the liquid medicine in the buffer tank, thereby maintaining a stable liquid medicine flow rate. To ensure the reliable operation of the system, the flow meter can also be equipped with an alarm function. When the liquid medicine flow rate is abnormal, it can issue an alarm to prompt the staff to take measures to avoid problems such as the filling of the bottle not being full or the appearance of bubbles in the assembled liquid medicine due to insufficient liquid medicine.

[0054] By combining the intuitive display of the transparent tube with the accurate measurement of the flow meter, the liquid medicine filling device can achieve a high degree of control over the filling volume of the liquid medicine, ensuring that the capacity of each bottle of liquid medicine meets the standard.

[0055] Flow monitoring not only improves the filling efficiency but also ensures the quality of liquid medicine filling. It helps to reduce the product rejection rate caused by insufficient or excessive liquid medicine and lowers the production cost.

Any approximation or similarity to the method structure of this application, or any technical deduction or replacement made under the premise of the concept of this application, should be regarded as the protection scope of this application.
