Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology. Background Technology

[0002] In conventional industrial production processes, devices capable of automating fluid replacement according to different needs are often required, and devices capable of automatically adding medications also exist. For example, the patent publication with authorization announcement number CN218075903U, authorization announcement date December 20, 2022, entitled "An Automated Medical Fluid Replacement Device," discloses a fluid replacement device including a fixed plate. A trapezoidal groove is formed on the top front side of the fixed plate, and a trapezoidal plate is arranged inside the trapezoidal groove. A screw sleeve is fixedly connected to the top front side of the trapezoidal plate, and a screw rod is threadedly connected inside the screw sleeve. A motor is fixedly connected to the right side of the screw rod, and the surface of the motor is fixedly connected to the surface of the fixed plate. Infusion bottles are arranged on both sides of the front side of the trapezoidal plate, and locking blocks are arranged on both sides of the infusion bottles. The rear side of the locking blocks is fixedly connected to the front side of the trapezoidal plate, and an infusion tube is arranged on the left side of the bottom front side of the fixed plate.

[0003] However, conventional automated devices currently have the following problems: 1. When the type and brand of the medicine solution are changed, cleaning the tank is inconvenient; 2. The output of the medicine solution is monitored by a flow pump. If the flow pump malfunctions, it may cause a decrease in the accuracy of the medicine solution addition. 3. Adding the medicine is difficult. It can be added by pouring or manually using equipment, which is not only troublesome but also risky. Alternatively, it can be added through automated pipelines, but the equipment is expensive and the pipelines need to be cleaned when the medicine changes, which is very troublesome.

[0013] The following is a brief explanation of the content represented by each of the accompanying drawings in this utility model specification: Figure 1 A schematic diagram of the structure of a drug monitoring and replenishment device; The labels in the above diagrams are: 1. Electronic scale; 2. Medicine container; 3. Control cabinet; 4. PLC; 5. Control panel; 6. Requirement point. Detailed Implementation

[0014] The following description, with reference to the accompanying drawings, details the specific implementation of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods. This will help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model.

[0015] This device uses an electronic scale 1 for weighing to determine the amount of liquid medicine used. Multiple electronic scales 1 can be set up and placed on the ground in the same area. The signal output terminal of each electronic scale 1 is connected to a PLC 4 via a signal line. The PLC 4 obtains the load data of the electronic scale 1. Each time the liquid medicine is used, the decrease in the weight of the electronic scale 1 indicates the weight of the liquid used, which can accurately obtain data. Furthermore, by knowing the weight of the medicine container 2 in advance, the remaining liquid medicine in the container can be known, thus eliminating the cost of using a liquid level sensor and knowing when to replenish the liquid medicine. Moreover, the high-precision electronic scale 1 is inexpensive, which is much cheaper than improving the accuracy of sensors, pumps, and other components.

[0016] The device is equipped with at least one electronic scale 1. The number of electronic scales 1 can be set as needed, such as about 4 or 5. Of course, the system itself is relatively simple. If more medicine containers need to be monitored after the equipment is installed, only one electronic scale 1 needs to be added. Each electronic scale 1 is connected to and outputs a weight signal to PLC 4. PLC 4 is connected to a control screen 5 that displays the weighing data. PLC 4 obtains the data from electronic scale 1 and sends it to the control screen 5 for display. The control screen 5 is a touch screen, and it can also be operated through the touch screen, such as tare the electronic scale 1, to improve the monitoring functionality.

[0017] The weighing plate of electronic scale 1 is equipped with a medicine container, which is the original packaging of the medicine. This way, each time a new medicine is placed on electronic scale 1 after removing the new medicine packaging, the monitoring can be completed. This makes it convenient to replace or replenish the medicine, and there is no need to clean the container when changing the type or brand of the medicine. Of course, a dedicated open container for storing medicine can also be provided, but when using a dedicated container, cleaning may be required when changing the type or brand of the medicine.

[0018] Each medicine container is equipped with an electronic pump. The outlet of the electronic pump is connected to the place where the medicine is used via a pipe. The medicine container has an opening at the top, through which the electronic pump is inserted into the medicine container. The pipe is a flexible tube, which allows the electronic pump to be easily placed into the medicine container for pumping. The end of the flexible tube is connected to the medicine application point. The electronic pump is preferably an electronic flow pump with flow statistics function. This dual redundancy design of electronic pump + electronic scale 1 can improve the accuracy of medicine dosage and can detect the failure of a component in time. The electronic pump is connected to control cabinet 3 via a data cable. Control cabinet 3 communicates with PLC 4, so the controller can control each electronic pump and obtain the working information (pumping liquid value) and send it to PLC 4. PLC 4 can compare the weight reduction value of electronic scale 1 (the comparison needs to be converted into units by density). When the difference of the comparison result exceeds the threshold, an alarm can be sounded through the speaker of the touch screen, so that the staff can be notified of the failure in time.

[0019] The signal input terminal of control cabinet 3 is connected to demand point 6 via a data cable. Demand point 6 is a device that uses the liquid medicine. The device uses a control signal to drive the electronic pump of control cabinet 3 to deliver the liquid medicine quantitatively to demand point 6.

[0020] In addition, the weighing plate has a ring of upturned edges around it, which provides restraint when placing the liquid medicine container and reduces the chance of improper placement. At the same time, the weighing plate of the electronic scale 1 is equipped with a humidity sensor, which is connected to and outputs a sensing signal to the PLC4. If the liquid medicine container leaks, the humidity sensor can detect it in time and the PLC4 can use the touch screen to issue an alarm.

[0021] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
