Description

Technical Field

[0002] The continuous improvement of medical standards has brought more and more perfect medical services to people, but more and more medical waste has also been generated during the medical treatment process. At present, each medical and health service institution generates a large amount of medical waste every day. This medical waste may contain a large number of pathogenic microorganisms and harmful chemical substances, and even radioactive and damaging substances. It is an important risk factor for causing disease transmission or related public health problems. Collecting and treating this medical waste has also become an important task for hospitals.

[0059] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0060] The purpose of the present invention is to provide a medical waste recycling vehicle, method and system, which reduce the error rate of manual operations of recycling personnel and improve the medical waste recycling efficiency through the paperless operation of medical waste recycling.

[0061] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0062] This embodiment provides a medical waste recycling vehicle, Figure 1 This is the structure diagram of the medical waste recycling vehicle provided by the embodiment of the present invention. Refer to Figure 1 , the medical waste recycling vehicle includes: a medical waste storage box 1 and wheels, and a module unit box 2 equipped with a weighing module, a positioning module, a printing module and a control module. The materials of the medical waste storage box 1 and the module unit box 2 are stainless steel materials.

[0063] The wheels are installed below the medical waste storage box 1; the module unit box 2 is fixed on the outer wall of the medical waste storage box 1. The number of wheels is multiple. In this embodiment, the wheels are 4 universal wheels. Two of the universal wheels at one end of the medical waste storage box 1 are equipped with angle locking switches 3. The two universal wheels with angle locking switches 3 are the front wheels of the medical waste recycling vehicle, and the two universal wheels without angle locking switches 3 are the rear wheels of the medical waste recycling vehicle. A brake connecting rod 4 is installed between the two rear wheels. The brake connecting rod 4 is connected to the brake pads of the two rear wheels at the same time. The brake connecting rod 4 is connected to the control module through a connecting rod spring.

[0064] When the medical waste recycling vehicle is in a narrow space, the angle locking switch 3 is turned on, and the front wheels are in the universal wheel mode for convenient turning. When the medical waste recycling vehicle is on a straight road surface, the angle locking switch 3 is turned off, and the front wheels are in the directional wheel mode for convenient movement.

[0065] The weighing module, the positioning module, and the printing module are all connected to the control module.

[0066] The weighing module is used to weigh the medical waste and transmit the weight information of the medical waste to the control module.

[0067] The weighing module is specifically arranged in the weighing storage box of the module unit box body 2. The weighing module specifically includes: a load-bearing support column and a weighing scale.

[0068] The load-bearing support column includes: a support rod, a limit hinge 5, and a spring limiter.

[0069] One end of the support rod is connected to the side opposite to the weighing surface of the weighing scale through the limit hinge 5, and a wide rubber support pad 6 is installed at the other end of the support rod.

[0070] The spring limiter is installed in the limit hinge 5.

[0071] One end of the weighing scale is movably connected to the weighing storage box; the weighing scale is connected to the control module; the weighing scale is used to obtain the weight information of the medical waste and transmit the weight information to the control module.

[0072] The load-bearing support column is used to support the weighing scale and the weighed medical waste.

[0073] The weighing module is fixed on the module unit box body 2 through a dedicated weighing storage box. When the medical waste recycling vehicle moves, the weighing scale is retracted into the weighing storage box. When weighing is required, the weighing module is lowered. The support rod is connected to the side opposite to the weighing surface of the weighing scale through the limit hinge 5. The limit hinge 5 is equipped with a spring limiter, and the spring limiter includes two limit angles of 0° and 90°. When weighing medical waste is required, lift the support rod, adjust the support rod to 90°, and the spring in the spring limiter in the limit hinge 5 is stretched. When the angle reaches 90°, the spring contracts and clamps the support rod. At this time, lower the weighing scale, and the support rod forms a 90° support foot with the ground, providing the maximum support force through the wide rubber support pad 6 at the other end of the support rod. After weighing is completed, retract the weighing scale, gently press the support rod, the spring is stretched, and when the support rod is adjusted to 0°, the spring contracts again to clamp the support rod, ensuring the stability of the support rod during the movement of the medical waste recycling vehicle. After the recycling personnel complete the recycling and weighing, the weight information is automatically uploaded to the control module through the excitation signal of the weighing sensor of the weighing scale.

[0074] The positioning module is used to obtain the current position information of the medical waste recycling vehicle and transmit the current position information to the control module.

[0075] The positioning module specifically includes: an outdoor positioning device and an indoor positioning device.

[0076] Both the outdoor positioning device and the indoor positioning device are connected to the control module.

[0077] The outdoor positioning device is used to obtain the position information of the medical waste collection vehicle outdoors. The outdoor positioning device adopts the Global Positioning System (GPS) and / or the Beidou satellite navigation system.

[0078] The indoor positioning device is used to obtain the position information of the medical waste collection vehicle indoors. The indoor positioning device adopts an interrogator of an active RFID electronic tag; the transponder of the active RFID electronic tag is set in the departments and / or wards of the hospital. The indoor positioning of the medical waste collection vehicle selects the active RFID (Radio Frequency Identification) positioning technology to achieve the "room-level" positioning function. When the medical waste collection vehicle reaches the collection point in the departments and / or wards of the hospital, the low-frequency RFID signal emitted by the transponder (positioning base station) in the departments and / or wards will trigger the interrogator (active RFID tag) in the wake-up module unit box 2 and communicate. The interrogator uploads the department information to which the medical waste belongs received through the RS232 serial port to the control module to realize the binding of the medical waste and the department information of the place where the medical waste belongs.

[0079] The control module is used to save and transmit the received weight information and the current position information to the printing module. The control module stores a preset moving boundary alarm range of the medical waste collection vehicle in its memory. The control module is also used to judge whether the movement of the medical waste collection vehicle exceeds the preset moving boundary alarm range according to the current position information of the medical waste collection vehicle obtained by the positioning module, and alarms when the medical waste collection vehicle exceeds the preset moving boundary alarm range to prevent the spread and pollution of medical waste.

[0080] The printing module is used to print the received weight information and the current position information. The control module transmits through the RS232 serial port to drive the printing module to print.

[0081] The medical waste storage box 1 is used to store medical waste.

[0082] The side wall and the top of the medical waste storage box 1 are provided with recovery ports to facilitate the putting in and taking out of medical waste.

[0083] To avoid pollution problems such as leakage of medical waste during transportation, the bottom of the medical waste storage box 1 is integrally welded to ensure the sealing of the medical waste storage box.

[0084] The bottom of the medical waste storage box 1 is provided with a drainage valve, which is convenient for discharging the liquid after cleaning the medical waste storage box.

[0085] A disinfection module is provided inside the medical waste storage box; the disinfection module is connected to the control module.

[0086] The disinfection module uses ultraviolet disinfection lamps.

[0087] The control module is also used to control the disinfection time of the interior of the medical waste storage box by controlling the turning-on time of the ultraviolet disinfection lamp. In practical applications, the control module can control the disinfection time by controlling the power-on time of the ultraviolet disinfection lamp.

[0088] The module unit box 2 is also equipped with a touch panel, which is connected to the control module. The touch panel and the control module communicate through a Mobile Industry Processor Interface (MIPI interface). The touch panel is used to obtain the type information of the medical waste and the identity information of the recycling personnel using the medical waste recycling vehicle. In this embodiment, the touch panel uses a touch screen. After the control module receives the weight information sent by the weighing module, it forms a voice broadcast and a touch button on the touch screen to prompt the recycling personnel to confirm the type of medical waste. After the recycling personnel confirm the type information and weight information of the medical waste, the weighing of the medical waste is completed, and the touch screen sends the confirmed weight information and the type information of the medical waste to the control module.

[0089] The control module is also used to obtain the type information of the medical waste and the identity information of the recycling personnel using the medical waste recycling vehicle through the touch panel.

[0090] The medical waste recycling vehicle is also equipped with an automatic obstacle avoidance module, a brake switch 7 and a foot brake device 8. The automatic obstacle avoidance module includes a plurality of photoelectric distance sensors, which are installed around the body of the medical waste recycling vehicle. The photoelectric distance sensors are used to detect the distance between the medical waste recycling vehicle and the obstacle. The foot brake device 8 is installed in the middle of the brake connecting rod 4. Both the brake switch 7 and the foot brake device 8 are connected to the connecting rod spring by wire and can pull the connecting rod spring.

[0091] When one or more of the photoelectric distance sensors sense that the distance between the medical waste recycling vehicle and the obstacle is less than the set detection distance, the digital signal transmitted by the photoelectric distance sensor to the control module changes in level. The control module makes the brake connecting rod 4 act through the connecting rod spring, and the brake pads of the rear wheels fall, realizing the simultaneous braking of the two rear wheels. When automatic braking occurs, after confirmation by the recycling personnel, the braking state is released through the brake switch 7. The recycling personnel can realize the braking and braking release of the vehicle by stepping on the foot brake device 8.

[0092] The medical waste recycling vehicle further includes a handheld terminal.

[0093] The control module is further configured to obtain the weighing time information when weighing medical waste, generate barcode information using the obtained data information, and transmit the barcode information and the data information to the printing module for printing; the data information includes: weight information, current location information, type information of medical waste, weighing time information, and identity information of the recycling personnel. The control module of each medical waste recycling vehicle can edit a fixed unique identification number, and the data information further includes the identification number of the control module of the medical waste recycling vehicle, which is convenient for searching and tracing relevant information of medical waste. The barcode information includes barcodes and QR codes.

[0094] The handheld terminal is used to scan the barcode information printed by the printing module and upload the data information corresponding to the barcode information, so as to realize the full closed-loop supervision of medical waste during the recycling process. The handheld terminal uses a personal digital assistant (PDA).

[0095] A power supply module is also installed in the module unit box 2. The power supply module consists of a large-capacity industrial lithium battery pack. The power supply module supplies power to each module in the module unit box to ensure the normal use of the medical waste recycling vehicle during movement.

[0096] When the medical waste recycling vehicle recycles medical waste, it weighs the recycled medical waste. At the same time, the positioning module obtains the current location information of the medical waste recycling vehicle, combines the weight information of the medical waste with the place of origin of the medical waste, prevents the weight deviation of the recycled medical waste, and can trace the place of origin of the medical waste; the control module saves and transmits the received weight information and current location information to the printing module for printing, avoiding the problem of unclear handwriting in manually recording medical waste information. At the same time, the data information is saved in the control module, which is convenient for the storage and search of medical waste information, realizes the paperless operation of medical waste recycling, reduces the error rate of manual operation by recycling personnel, and improves the efficiency of medical waste recycling.

[0097] This embodiment also provides a medical waste recycling method. Figure 2 It is a flowchart of the medical waste recycling method provided by the embodiment of the present invention. Refer to Figure 2 , the medical waste recycling method includes:

[0098] Step 101, obtain the identity information of the recycling personnel using the medical waste recycling vehicle, the vehicle information of the medical waste recycling vehicle, and the current location information of the medical waste recycling vehicle.

[0099] Step 102, use the current location information to determine whether the medical waste recycling vehicle is located in the department of a hospital, and obtain a first judgment result.

[0100] Step 103, if the first judgment result is yes, obtain the weight information and type information of the medical waste, as well as the department information where the current medical waste collection vehicle is located.

[0101] Step 104, generate barcode information using the obtained data information, print the barcode information, and upload it; the data information includes: vehicle information, weight information, type information of the medical waste, identity information of the recycling personnel, and department information where the current medical waste collection vehicle is located.

[0102] Step 105, if the first judgment result is no, determine whether the medical waste collection vehicle exceeds the preset moving boundary alarm range to obtain a second judgment result.

[0103] Step 106, if the second judgment result is yes, give an alarm.

[0104] This embodiment also provides a medical waste collection system, including: a weighing module, a printing module, and a control module.

[0105] Both the weighing module and the printing module are connected to the control module.

[0106] The weighing module is used to obtain the weight information of different types of medical waste and transmit the weight information to the control module.

[0107] The control module is used to obtain the type information of the medical waste and the identity information of the recycling personnel for recycling the medical waste, and transmit the type information, identity information, and weight information to the printing module and upload them.

[0108] The printing module is used to print the type information, identity information, and weight information.

[0109] This embodiment also provides a medical waste collection management system, including: an in-hospital medical waste collection subsystem and a clinic medical waste collection subsystem.

[0110] 1) In-hospital medical waste collection subsystem

[0111] Medical waste in the hospital is scattered in various departments and outpatient clinics within the hospital. Medical waste is characterized by numerous generation points, diverse types, large weights, and frequent recycling cycles. Currently, the body of the medical waste recycling vehicle used in the hospital is made of plastic material, with low mechanical strength and no functions such as weighing and printing. After the medical waste is weighed at the generation site, the recycling personnel record the data manually through paper materials, and the data saved is extremely prone to errors and difficult to count and track. In this embodiment, a movable medical waste recycling vehicle (hereinafter referred to as the recycling vehicle) is applied during the recycling of medical waste in the hospital. The recycling vehicle includes a medical waste storage box body and a module unit box body, and the medical waste storage box body and the module unit box body are connected by welding. The medical waste storage box body is used to store the collected medical waste, and the module unit box body is used to implement functions such as weighing and printing. After the recycling personnel collect the medical waste, they use the weighing module of the recycling vehicle to weigh it. After weighing, the data information of the medical waste is automatically recorded, printed, and uploaded to ensure the accuracy of the data information. At the same time, the medical waste is placed in the medical waste storage box body to facilitate the centralized recycling of medical waste and improve the work efficiency of the recycling personnel.

[0112] For the structural diagram of the recycling vehicle's box body, see Figure 3 , the box body part of the recycling vehicle serves as the overall outer shell of the recycling vehicle and is made of high-strength stainless steel material. The recycling vehicle box body includes a medical waste storage box body and a module unit box body. Recycling openings are provided on the side and above of the medical waste storage box body to facilitate the putting in and taking out of medical waste. To avoid pollution problems such as liquid leakage during the transportation of medical waste, the bottom of the medical waste storage box body is integrally welded to ensure the sealing of the medical waste storage box body. At the same time, to facilitate the discharge of the liquid after cleaning the medical waste storage box body, a drain valve is installed at the bottom of the medical waste storage box body. To facilitate the movement of the recycling vehicle within the hospital, the recycling vehicle is supported by four universal wheels, and two front wheels are equipped with angle locking switches. When the recycling vehicle is driving in a narrow space, the locking switch is turned on, and the front wheels are in the universal wheel mode, which is convenient for turning; when the recycling vehicle is driving on a straight road surface, the locking switch is turned off, and the two front wheels are in the fixed-wheel mode, which is convenient for moving.

[0113] The module unit box of the recycling vehicle is isolated from the medical waste storage box, and the two boxes are connected by welding. A control module is installed in the module unit box, and the control module is used to collect, process, and upload the data information generated during the medical waste recycling process. At present, most of the medical waste recyclers in medical institutions are older and not very proficient in operating intelligent devices. To facilitate the recycling operation, a high-strength touch screen is installed on the control module to achieve human-computer interaction. The touch screen is connected to the control module through the MIPI interface to achieve communication. During the recycling process, the control module issues corresponding voice operation prompts according to different operations, and displays the touch buttons for confirming operations on the touch screen. The control module can edit a fixed unique identification number. The control module has a login interface for the hospital's medical waste recycling system. The recycler binds the logged-in account with the unique identification number of the control module to realize the binding of the recycler's identity information and the information of the recycling vehicle.

[0114] The module unit box includes: a control module, a weighing module, a printing module, a positioning module, an automatic obstacle avoidance module, and a disinfection module. For the connection diagram of the control module and the other modules in the module unit box, see Figure 4 , the positioning module is connected to the control module through the RS232 communication interface, the disinfection module transmits data to the control module through digital signals, the automatic obstacle avoidance module transmits data to the control module through digital signals, the printing module is connected to the control module through the RS232 communication interface, and the weighing module transmits data to the control module through excitation signals. The control module includes a central processing unit (CPU), a voice broadcaster, and a display screen. The CPU is connected to the voice broadcaster through the I2S bus, and the CPU is connected to the display screen through the MIPI interface. The display screen uses a touch screen and is used to display the data transmitted by the control module; the voice broadcaster is used for voice broadcasting. The CPU in this embodiment can select a single-chip microcomputer with the model of STM32.

[0115] A positioning module is installed in the module unit box. The positioning module consists of an outdoor positioning device and an indoor positioning device. The outdoor positioning device selects GPS and / or Beidou satellite navigation system for positioning. A corresponding mobile boundary alarm range is set in the control module. When the recycling vehicle exceeds the boundary, an automatic alarm is triggered to prevent the spread and pollution of medical waste. The indoor positioning device selects active RFID positioning technology to achieve the "room-level" positioning function. When the recycling vehicle arrives at the recycling point in the ward area of the hospital, the low-frequency RFID signal emitted by the positioning base station in the department will trigger the active RFID tag in the module unit box to wake up and communicate. The active RFID tag uploads the received department information to the control module through the RS232 serial port to realize the binding of the department information of medical waste.

[0116] A weighing module is installed inside the module unit box, and the weighing module is used to weigh medical waste. The weighing module is fixed on the vehicle body of the recycling vehicle through a dedicated weighing storage box. When the recycling vehicle moves, the weighing module is retracted into the weighing storage box; when weighing is required, the weighing module is lowered. The weighing module includes a weighing scale and a weighing support column. One end of the weighing scale is movably connected to the weighing storage box. The weighing support column is installed on the lower surface of the weighing scale (i.e., the side opposite to the weighing surface of the weighing scale). A wide rubber support pad is installed at the end of the weighing support rod. The weighing support rod is connected to the weighing scale through a limit hinge, and a spring limiter is installed in the limit hinge. The spring limiter has two limit angles of 0° and 90°. When weighing medical waste is required, lift the weighing support rod. After adjusting the weighing support rod to 90°, the spring in the limit hinge is stretched. When the angle of the spring limiter reaches 90°, the spring contracts and clamps the weighing support rod. At this time, lower the weighing scale, and the weighing support rod forms a 90° support foot with the ground, providing the maximum support force through the wide rubber pad at the end of the weighing support rod. After weighing the medical waste is completed, lift the weighing scale and gently press the weighing support rod. The spring in the limit hinge is stretched. When the support rod is adjusted to 0°, the limit hinge spring contracts again and clamps the weighing support rod to ensure the stability of the weighing support rod during the movement of the recycling vehicle. After the recycling personnel complete the recycling weighing, the weight information of the medical waste obtained by the weighing module is automatically uploaded to the control module through the excitation signal of the weighing sensor of the weighing scale, and voice announcements and touch buttons are formed on the touch screen to prompt the recycling personnel to confirm the type of medical waste. After the recycling personnel confirm, the weighing of the medical waste is completed.

[0117] A printing module is installed inside the module unit box, and the printing module prints the data sent by the control module. The control module generates corresponding barcode information based on the bound recycling personnel information, vehicle information of the recycling vehicle, located department information, weight information of medical waste, type information of medical waste, weighing time information, etc., and transmits it to drive the printing module through the RS232 serial port, printing out the corresponding data information and barcode information. The recycling personnel scan and upload the barcode information through the operation of the handheld terminal PDA to realize the full closed-loop supervision of medical waste during the recycling process.

[0118] An automatic obstacle avoidance module is installed inside the module unit box. The automatic obstacle avoidance module collects information through multiple photoelectric distance sensors installed around the body of the recycling vehicle. A brake link is installed between the two rear wheels of the recycling vehicle. The brake link is connected to the brake pads of the two rear wheels at the same time. The brake link operates through the link spring connected to it, and the link spring is connected to the control module. When one or more photoelectric distance sensors sense that the distance between the recycling vehicle and the obstacle is less than the set detection distance, the digital signal connected between the photoelectric distance sensor and the control module changes in level. The control module pulls the link spring, the brake link operates, and the rear wheel brake pads fall, realizing the simultaneous braking of the two rear wheels. A brake switch and a foot brake device are installed on the module unit box at the same time. The brake switch and the foot brake device are connected to the link spring by wire and can pull the link spring. The foot brake device is installed in the middle of the brake link. After automatic braking occurs and is confirmed by the recycling personnel, the braking state can be released through the brake switch. The recycling personnel can realize the braking and braking release of the recycling vehicle by stepping on the foot brake device. The set detection distance of the photoelectric distance sensor can be set through the CPU.

[0119] A power supply module is installed inside the module unit box. The power supply module consists of a large-capacity industrial lithium battery pack. It supplies power to each module inside the module unit box to ensure the normal use during the movable process of the recycling vehicle.

[0120] A disinfection module is installed inside the medical waste storage box. The disinfection module is installed inside the medical waste storage box body. The disinfection module realizes the disinfection of the inside of the recycling vehicle box through ultraviolet disinfection lamps. The disinfection module communicates with the control module through digital signals. After the recycling personnel complete the vehicle cleaning, they can select the corresponding disinfection time and disinfection duration through the control module, and can also realize the function of timed disinfection.

[0121] For the flow chart of the collection of outpatient medical waste in the hospital, see Figure 5 , during the use of the recycling vehicle, sometimes due to the complex building environment in the hospital, the recycling vehicle cannot reach many places, such as the outpatient area. For the collection of outpatient medical waste, in this embodiment, adhesive outpatient labels are reserved at the outpatient collection site. The outpatient labels are printed with QR codes of department information and selectable medical waste type information. When collecting outpatient medical waste, the corresponding outpatient label is pasted on the recycling bag of the medical waste according to the outpatient information, and the type of medical waste is confirmed on the outpatient label. After the collection of medical waste is completed, centralized weighing is carried out at the recycling vehicle. After weighing, the type of medical waste is confirmed and the corresponding barcode information and data information are printed. The outpatient label and barcode information (printed label) are scanned through the PDA, and the data corresponding to the outpatient label and barcode information is uploaded to realize the recycling data management of outpatient medical waste.

[0122] For the flow chart of the collection of in-patient area medical waste in the hospital, seeFigure 6 The recycler logs in personal information through the touch screen, and the positioning module conducts in-hospital positioning to determine the location information of the recycling vehicle and the ward to which the medical waste belongs. The medical waste is weighed, and the type information of the medical waste is confirmed through the touch screen. The control module transmits the acquired data information and the generated barcode information to the printing module for data printing, and the PDA scans the barcode information to upload the data of the medical waste.

[0123] 2) Clinic medical waste recycling subsystem

[0124] The clinic medical waste recycling part mainly realizes the recycling management of medical waste in medical clinics. Clinics are scattered, and the types of medical waste they generate are few, the weight is light, and the recycling frequency is low. If a dedicated recycling vehicle is used for collection, the utilization rate of the recycling vehicle will be low, which will instead lead to low recycling efficiency. In this embodiment, the clinic medical waste is weighed and managed in a 'localized' manner, that is, the medical waste is weighed and the data is uploaded in the clinic, and after weighing, it is transported to the temporary storage area in the community hospital for data verification and storage. The clinic includes a weighing module, a printing module, and a control module, etc. Both the weighing module and the printing module are connected to the control module through Bluetooth, and the control module uses a PDA.

[0125] For the flow chart of medical waste recycling in the clinic, see Figure 7 The recycler first logs in to the medical waste recycling system through the PDA; then collects the medical waste, packs and weighs the medical waste according to different types. After weighing, the weighing module uploads the weight information of different types of medical waste to the PDA through Bluetooth. The recycler confirms the type information of the medical waste on the PDA. The printing module is programmed with the unique identification number of the corresponding clinic. After confirming the type information, the PDA obtains the unique identification number of the clinic in the printing module, and generates a corresponding QR code with the recycler's identity information, weight information, type information, clinic information (unique identification number of the clinic), and time information, and transmits the above data information and the QR code to the printing module. Then, the printing module is driven through Bluetooth. After receiving the data transmitted by the PDA, the printing module prints, and pastes the QR code printed by the printing module as a label on the collected medical waste. At the same time, the PDA uploads the recycler's identity information, weight information, type information, clinic information, and time information to the medical waste recycling system to realize the binding of medical waste data. The recycler puts the collected medical waste into a turnover box, transports the medical waste to the designated temporary storage area of the community hospital through the turnover box, and then verifies and uploads the medical waste data by scanning the QR code pasted on the medical waste, and stores the medical waste in the temporary storage area of the community hospital to realize the recycling management of medical waste in the clinic. The printing module can use a printer, and the model can be selected as Gainscha GP-3120.

[0126] With the continuous development of current medical technology, while facilitating people's access to medical services, more and more medical waste has been generated in major medical institutions. There were many loopholes in the previous medical waste recycling, resulting in leakage and pollution of medical waste. The Jiangsu Provincial Health Commission issued the "Notice on Further Strengthening the Prevention and Control of Medical Waste Pollution in the Whole Province" Document No. 2

[2019] and the "Basic Function Specifications (Trial) of the 'Medical Waste Management (Supervision) System' in Jiangsu Province" Document No. 38

[2019] . The documents emphasized the process and supervision of medical waste recycling. The medical waste recycling management system of this embodiment realizes the full-closed-loop recycling supervision of medical waste by binding and supervising the identity information of recycling personnel, recycling vehicle information, department information, medical waste weight information, medical waste type information, etc., starting from the source of medical waste recycling, and greatly improving the supervision intensity of medical waste recycling. Through the operation interface of the touch screen and the voice broadcast of the operation process, it is convenient for on-site operators, ensuring safety, efficiency and intelligence in actual use, and improving the recycling efficiency of medical waste.

[0127] The medical waste recycling management system realizes the supervision of the medical waste recycling process through the application of information technology; during the medical waste recycling process, the recycling personnel only need to complete simple selection and confirmation operations to complete the recycling and data upload of medical waste. The control module automatically generates an electronic report based on the uploaded data, realizing the paperless operation of medical waste recycling, reducing the error rate of manual operation by personnel, and improving the recycling efficiency of medical waste.
