Description

Technical Field

[0001] This invention relates to the field of information management of medical waste, specifically a weighing device for medical waste information collection and management based on RFID technology. Background Technology

[0002] Medical waste generated within hospital departments contains a large number of pathogens. Therefore, it is usually collected directly or indirectly through dedicated medical waste collection bags, hereinafter referred to as "medical waste bags." These bags are sealed and collected by designated collectors, who then transport them to the hospital's temporary medical waste storage point. When collecting medical waste bags within the department, collectors are required to record information according to regulations. Currently, this recording of information is generally done manually using paper forms. This method of recording information using paper forms lacks oversight, leading to inaccurate information and making it impossible to compare with information from subsequent stages.

[0003] When collectors transport medical waste bags to the medical waste temporary storage point, the bags lack information markings, making it impossible to identify which department they belong to. This prevents verification against information from the department's collection process. Furthermore, the manual recording of information for each bag at the storage point is labor-intensive, often only recording the total weight. This lack of verification and recording of individual bag information leads to missing information at each stage, making verification difficult. Because the medical waste bags transported to the temporary storage point cannot be identified as belonging to any department, and because inaccurate or missing information can occur at each stage, it's impossible to determine which bag was lost in the event of a medical waste loss, hindering traceability and making it difficult to track lost medical waste.

[0004] Because medical waste contains a large number of pathogens, it can cause great harm if it enters society without proper treatment. Therefore, it is necessary to increase information technology equipment to assist hospitals in the information management of medical waste in order to prevent the loss, leakage and spread of medical waste within the hospital. Summary of the Invention

[0005] The purpose of this invention is to provide a medical waste information collection and management weighing platform based on RFID technology. By loading different embedded control systems and connecting them to a smart cloud management platform for medical waste via the Internet of Things, this invention aims to solve the problems of inaccurate information on medical waste bags when manually recording data on paper in the departmental collection process, and the difficulties in tracing lost medical waste bags and verifying information on medical waste bags at the temporary storage point.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a weighing platform device for medical waste information collection and management based on RFID technology, comprising a platform chassis, a platform tray, a weighing sensor, a control board, a support rod, a weighing head, and a four-channel RFID reader / writer module.

The universal rollers are equipped with brakes. The directional rollers and universal rollers are used for pushing the device when it is placed on the ground. Two spring-loaded ball bearing mounting plates are respectively provided on the front two sides of the bottom of the platform chassis, with a spring-loaded ball bearing in the middle of the mounting plate. The ball bearing inside the spring-loaded ball bearing can retract and extend. A spring-loaded ball bearing is respectively provided on the left and right vertical beams at the bottom of the platform chassis. A spring-loaded pin with a button is provided; pressing it releases a locking pin inside the spring-loaded pin. A weighing sensor is located at the center of the top of the platform scale base. This weighing sensor can weigh objects and is connected to both the lower platform scale base and the upper platform scale tray via a third screw. A third RFID reading antenna module is located at the front bottom of the platform scale tray. This module can read RFID tags and adjust the reading angle. A platform scale panel mounting base is located above the platform scale tray, and a platform scale panel is mounted on top of the mounting base. A plastic sticker is located on top of the platform scale panel. A square tube is located behind the platform scale base, with a spring-loaded pin on each of its left and right sides. A damping hinge is located at the rear, allowing rotation within a certain angle. This hinge is connected to the front square tube and the upper support rod via a fourth screw. The support rod can rotate within a certain angle via the damping hinge. A support rod panel is located at the front of the support rod. A triangular power socket is located on the left side of the support rod. A lower mounting plate is located at the bottom of the support rod. A transformer power supply mounting plate is located at the bottom inside the support rod. A transformer power supply is located above the transformer power supply mounting plate, converting 220V to 24V. A four-channel RFID reader / writer module mounting plate and a first RFID reading antenna module are located in the middle of the support rod's interior. The first RFID reading antenna module can read RFID tags. The four-channel RFID reader / writer module is located behind the mounting plate. A second RFID reading antenna module is located inside the upper part of the support rod. This second RFID reading antenna module can read RFID tags and adjust the reading angle. A support rod upper mounting plate is located at the top of the support rod, and a support rod rear door panel is located behind the support rod. A buckle is located on both the upper and lower sides of the support rod rear door panel; engaging these buckles allows the support rod rear door panel to be removed. A medium-sized damping shaft is located above the support rod upper mounting plate. This medium-sized damping shaft has a wire hole in the middle and can rotate within a certain angle. The medium-sized damping shaft is connected to the upper damping shaft mounting plate and the lower support rod upper mounting plate respectively via second screws.The damping shaft mounting plate has a small damping shaft on each of its left and right sides. These small damping shafts can rotate within a certain angle. They are connected to the damping shaft mounting plate and the weighing head via first screws. The weighing head has a display screen and an IC card reader module at its front. A power switch and a patch antenna are located on the left side of the weighing head. A waterproof connector with a wire hole is located at the bottom of the weighing head. A weighing head mounting base plate is located at the rear of the weighing head. A hollow rubber column is located in front of the base plate. A control board and a card rail are located in front of the hollow rubber column. The control board can receive and process data from various electronic components. A network module is located in front of the card rail and connects to the card rail via a groove. The network module can upload and receive medical waste information via the patch antenna.

[0007] Furthermore, the support rod has an opening at the front, and the support rod can be rotated to the top of the square tube via the damping hinge. At the same time, the support rod can also be rotated to the bottom of the platform scale chassis via the damping hinge.

[0008] Furthermore, the support rod has through holes on both sides at the bottom front, and a spring pin is provided on each side of the square tube. After the support rod is rotated to the fixed position above the square tube, pressing the button on the spring pin will cause the spring pin to pop out and insert into the through hole at the bottom of the support rod, thereby limiting the displacement of the support rod.

[0009] Furthermore, the support rod has through holes on both sides, and a spring pin is provided on each of the vertical beams on both sides of the bottom of the platform scale chassis. After the support rod is rotated to the fixed position at the bottom of the platform scale chassis, pressing the button on the spring pin will cause the spring pin to pop out and insert into the through holes on both sides of the support rod, thereby restricting the displacement of the support rod.

[0010] Furthermore, the weighing head is provided with circular grooves on the left and right sides. When the support rod rotates, it can drive the weighing head to a fixed position at the bottom of the platform scale. The spring ball bearings installed on the front two sides of the bottom of the platform scale automatically pop out and lock into the circular grooves on the left and right sides of the weighing head, thereby limiting the displacement of the weighing head.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. When this invention is loaded into the embedded control system of the departmental data collection process:

[0013] (1) The present invention is equipped with a precise weighing sensor at the bottom. After placing the medical waste bag with the RFID tag on the platform of the device, the device will automatically identify the RFID code of the RFID tag on the medical waste bag, automatically weigh the medical waste bag and upload the medical waste bag information to the medical waste smart cloud management platform. The medical waste smart cloud management platform automatically records the medical waste bag information, replacing manual paper records, and solving the problem of inaccurate information of medical waste bags when manual paper records are made in the department collection process.

[0014] (2) This invention features automatic RFID tag reading. RFID tags, encoded and entered into the medical waste smart cloud management platform, are affixed to each medical waste bag. Simply place the medical waste bag on the platform of this device, and it will automatically collect the RFID code, weight, operator, time, and department information of the medical waste bag and upload it to the medical waste smart cloud management platform. The platform automatically records the medical waste bag information and generates process information, while simultaneously starting a timer. If a medical waste bag fails to proceed to the next stage or is lost, the platform automatically generates an alarm work order for that bag. During tracing, the alarm work order can accurately pinpoint the lost bag, solving the problem of difficulty in tracing lost medical waste bags in the temporary storage point's inbound and outbound processes. Furthermore, the alarm work order can accurately retrieve the department, weight, time, and operator information of the lost medical waste bag, not only solving the problem of difficulty in tracing lost medical waste bags but also enabling the traceability of the lost medical waste bag.

[0015] 2. When the present invention loads the embedded control system of the temporary storage point inbound / outbound process:

[0016] (1) Simply place the medical waste bags that have been registered in the department or have been put into storage on the weighing platform. The equipment will automatically identify the RFID code of the RFID tag on the medical waste bag, automatically weigh the medical waste bag and upload the medical waste bag information to the medical waste smart cloud management platform. The medical waste smart cloud management platform will automatically verify whether the weight information of the medical waste bag is consistent with the weight information recorded in the previous step and provide feedback on the verification result of the equipment. This solves the problem of difficulty in verifying the medical waste bag information before and after the temporary storage point in the process of entering and leaving the warehouse.
