Description
Technical Field
[0001] The invention belongs to the technical field of medical waste disinfection, and in particular relates to a medical waste storage cabin with an automatic disinfection function. Background Art
[0002] In the field of medical waste treatment, safe storage and disinfection of medical waste are crucial links. Medical waste contains a large number of pathogens such as bacteria and viruses, which may lead to the spread of diseases if not properly managed. For example, if waste such as blood and body fluids containing viruses are not properly handled, they may be transmitted to other people through air, water and other channels.
[0003] At present, there are various designs of medical waste storage chambers on the market. Some of these devices are equipped with disinfection equipment and negative pressure equipment, which aim to reduce the pathogen content in the medical waste storage chamber through disinfection and negative pressure, and prevent cross-infection and environmental pollution. Negative pressure equipment prevents air leakage from the chamber by forming a negative pressure environment, thereby avoiding the spread of pathogens through the air.

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0029] like Figure 1-Figure 2 As shown, a medical waste storage cabin with automatic disinfection function includes a cabin body 1, a movable window assembly 2 and a first partition 31; the first partition 31 is arranged in the cabin body 1, and the cabin body 1 is isolated to form a first disinfection room 11 and a second disinfection room 12; the movable window assembly 2 is arranged in the first disinfection room 11, and forms a transition space with the first partition 31;
[0030] The first disinfection room 11 is provided with an ultrasonic device for separating dust in the medical waste downward and aerosol upward, and the second disinfection room 12 is used to collect the aerosol separated upward from the upper part of the first disinfection room 11;
[0031] A fixed window 311 is provided on the upper part of the first partition 31, and the fixed window 311 is connected to the transition space. The movable window assembly 2 is provided with a movable window 23 connected to the fixed window 311, and the movable window 23 adjusts the distance between the movable window 23 and the fixed window 311 according to the content of the aerosol in the first disinfection room 11;
[0032] It should be noted that the first partition 31 is arranged inside the cabin body 1, and is used to separate its space into a first disinfection room 11 and a second disinfection room 12. The first disinfection room 11 mainly processes the dust and aerosols generated in the medical waste through the built-in ultrasonic equipment, and the second disinfection room 12 is used to further collect and process the aerosols separated from the upper part of the first disinfection room 11.
[0033] The design of the first disinfection room 11 is based on the physical properties of dust and aerosols. Dust has a high density and tends to settle downward under the action of gravity, while aerosols tend to float upward with the airflow due to their low density. The first partition 31 not only plays a role of physical isolation in space division, but also connects with the transition space through the fixed window 311 on its upper part, thereby further optimizing the separation path of aerosols.
[0034] During specific operation, medical waste is stored in the first disinfection room 11, and the medical waste is vibrated or ultrasonic waves are sent using ultrasonic equipment in the first disinfection room 11, so that the dust is guided to the bottom collection device of the first disinfection room 11 under the combined action of gravity and negative pressure, and the aerosol is guided upward to the fixed window 311 area with the airflow. The fixed window 311 arranged on the upper part of the first partition 31 forms a transition channel that helps the aerosol to be further transmitted to the second disinfection room 12 through communication with the transition space.
[0035] The control system is used to detect the content of aerosol in the first disinfection room 11 and dynamically adjust the distance between the first disinfection room 11 and the fixed window 311 according to the content of aerosol in the first disinfection room 11; specifically, a sensor 41 is installed in the first disinfection room 11, and the sensor 41 is an aerosol concentration detection sensor 41. The sensor 41 is electrically connected to the main control unit. When the aerosol concentration exceeds a preset threshold, the main control unit issues an instruction based on the detection result to drive the movable window assembly 2 to adjust the position of the movable window 23 to reduce the distance between it and the fixed window 311, thereby accelerating the transfer process of the aerosol to the second disinfection room 12. When the aerosol concentration is lower than the preset value, the distance between the movable window 23 and the fixed window 311 automatically increases to maintain a stable air flow environment in the first disinfection room 11.
[0036] The second disinfection room 12 is specially used for receiving and further processing the aerosol transferred from the first disinfection room 11. Through the lower pressure environment formed in the second disinfection room 12 by the negative pressure component 43, the aerosol can be quickly inhaled and centrally processed. At the same time, a dust collection device is designed at the bottom of the first disinfection room 11. Through appropriate negative pressure adjustment, the dust is prevented from floating again due to airflow disturbance.
[0037] In summary, the medical waste storage chamber of the present application can achieve effective separation and disinfection of dust and aerosols, especially through the dynamic linkage design of the movable window assembly 2 and the fixed window 311, which improves the aerosol processing efficiency and ensures that the processing process in the first disinfection room 11 and the second disinfection room 12 is safe, stable and efficient.
[0038] In one embodiment, the control system includes a sensor 41, a second air pipe 42, a negative pressure component 43, a valve component 44 and a main control unit. The sensor 41 is arranged in the first disinfection room 11. The sensor 41 and the valve component 44 are electrically connected to the main control unit. The sensor 41 is used to detect the content of aerosol in the first disinfection room 11 and upload it to the main control unit. The air outlet of the second air pipe 42 is connected to the negative pressure component 43, and the air inlet is arranged at the upper part of the second disinfection room 12. The valve component 44 is arranged at the air inlet of the second air pipe 42, and the main control unit controls the opening degree of the valve component 44 according to the aerosol content; specifically, an aerosol concentration sensor 41 is arranged inside the first disinfection room 11, and the sensor 41 can monitor the concentration level of aerosol in the first disinfection room 11 in real time. The sensor 41 is connected to the main control unit through an electrical signal to form a data acquisition and feedback closed-loop system.
[0039] The structural design of the second air pipe 42 is intended to provide an effective aerosol processing channel for the second disinfection room 12. The air outlet is directly connected to the negative pressure component 43, and the air inlet is arranged at the upper part of the second disinfection room 12 to ensure that the gas input to the second air pipe 42 is mainly from the area with dense aerosol particles. In order to achieve dynamic control, the air inlet of the second air pipe 42 is equipped with a valve component 44, and the opening and closing degree of the valve component 44 is directly controlled by the main control unit.
[0040] When the aerosol concentration in the first disinfection room 11 rises to a preset threshold, the sensor 41 immediately uploads the detected concentration data to the main control unit. The main control unit calculates the optimal opening degree of the valve assembly 44 through a built-in control algorithm based on the changing trend of the aerosol concentration. Subsequently, the main control unit sends a control signal to the valve assembly 44 to adjust the valve opening size to optimize the transfer efficiency of the aerosol to the second disinfection room 12. At the same time, the negative pressure assembly 43 maintains a low-pressure environment in the second disinfection room 12 to guide the aerosol to the second disinfection room 12. In actual operation, when the aerosol concentration is high, the main control unit will instruct the valve assembly 44 to open fully, thereby accelerating the delivery of the aerosol to the second disinfection room 12 and avoiding its retention and accumulation in the first disinfection room 11. When the concentration drops to a safe range, the main control unit instructs the valve assembly 44 to gradually close to reduce unnecessary airflow consumption and maintain the energy efficiency of the overall system. This embodiment can reduce the aerosol concentration to a safe range in a short time, and the entire regulation process responds quickly and has strong stability. At the same time, the aerosol in the second disinfection room 12 is discharged to the filter through the human trachea, and the gas containing the aerosol is filtered by the filter before being discharged into the air.
[0041] In one embodiment, the movable window assembly 2 includes a regulating assembly 5, which is electrically connected to the main control unit. The regulating assembly 5 is used to drive the movable window 23 to move up and down according to the content of the aerosol in the first disinfection room 11, so as to quickly collect the aerosol in the second disinfection room 12. During operation, when the aerosol concentration sensor 41 in the first disinfection room 11 detects that the concentration increases beyond a preset safety threshold, the main control unit immediately generates a control signal through the built-in control logic, instructing the regulating assembly 5 to drive the movable window 23 to move upward. At this time, the distance between the movable window 23 and the fixed window 311 is reduced, forming a forced airflow path, thereby accelerating the process of the aerosol moving upward to the fixed window 311 and entering the second disinfection room 12. This action not only quickly clears the high-concentration aerosol in the first disinfection room 11, but also avoids the risk of secondary diffusion caused by its retention.
[0042] When the aerosol concentration returns to below the safe range, the main control unit will send instructions to gradually move the movable window 23 down to the initial position to increase the distance between the fixed window 311 and the movable window 23, and restore the normal airflow state in the first disinfection room 11. On the one hand, through the dynamic response capability of the control component 5, the rapid collection of aerosols can be completed in a short time to ensure the stability of the air quality in the first disinfection room 11; on the other hand, the precise displacement control of the movable window 23 avoids excessive energy consumption, while reducing mechanical wear during equipment operation and improving the reliability and life of the system; in addition, the entire control process is intelligently controlled by the main control unit without manual intervention, which greatly improves the level of automation of the operation.
[0043] In one embodiment, the movable window assembly 2 also includes a first blade 21 and a second blade 22; the first blade 21 and the second blade 22 are respectively arranged at the bottom and the top of the first disinfection room 11, and the movable window 23 is used to connect the first blade 21 and the second blade 22; the movable window 23 connects the transition space with the first disinfection room 11. In order to adapt to the movement of the movable window 23, the first blade 21 and the second blade 22 are both stretchable blades, that is, one end is anchored and the other end can relatively spread the blades.
[0044] In one embodiment, the regulating component 5 includes a steel cable 51, a pair of movable pulleys 52 and a pair of fixed pulleys 53; the two ends of the steel cable 51 are respectively anchored at the top and bottom of the same side of the first disinfection room 11, and the pair of fixed pulleys 53 are respectively arranged at the top and bottom of the first disinfection room 11, and the pair of fixed pulleys 53 are relative to the steel cable 51; the pair of movable pulleys 52 are respectively arranged at the top and bottom of the movable window 23, the side of the steel cable 51 close to the pair of movable pulleys 52 is connected to the steel cable 51, and the side of the pair of fixed pulleys 53 away from the steel cable 51 is connected; the steel cable 51 is the core transmission element of the regulating component 5, and its two ends are respectively anchored at the top and bottom of the same side of the first disinfection room 11, forming a load-bearing and transmission path throughout the entire system;
[0045] The combination of the fixed pulley 53 and the movable pulley 52 further enhances the control performance of the system. A pair of fixed pulleys 53 are respectively arranged at the top and bottom of the first disinfection room 11 and remain fixed relative to the steel cable 51. Its main function is to change the transmission direction of the steel cable 51. Through reasonable arrangement of the pulleys, it can drive the movable window 23 to move up and down.
[0046] The movable pulleys 52 are respectively arranged at the top and bottom of the movable window 23, and are designed to dynamically adjust the force direction of the steel cable 51 as the movable window 23 is displaced. A pair of movable pulleys 52 are connected to the steel cable 51 on one side close to the steel cable 51 in a rolling manner, ensuring that the movable pulleys 52 can slide smoothly as the movable window 23 moves up and down. During operation, when the main control unit sends a control signal, the fixed pulley 53 is rotated by the steel cable 51 to change the force direction of the steel cable 51 to achieve precise movement of the movable window 23. For example, when the aerosol concentration in the first disinfection room 11 is When the concentration increases, the fixed pulley 53 rotates to drive the steel cable 51 to move, causing a pair of movable pulleys 52 to move upward, thereby pushing the movable window 23 to slide upward, reducing the opening area between the transition space and the first disinfection room 11, and enhancing the guiding effect of the airflow on the aerosol; conversely, when the concentration decreases, the steel cable 51 is pulled in the opposite direction to push the movable window 23 to slide downward, expand the opening area, and restore the normal distribution of the airflow. The design of the pulley system makes full use of the mechanical cooperation between the fixed pulley 53 and the movable pulley 52, which significantly improves the operating stability and adjustment accuracy of the movable window 23.
[0047] In one embodiment, a driving member 54 is further included, and the driving member 54 is electrically connected to the main control unit. The driving member 54 is connected to a fixed pulley 53 arranged at the bottom, and is used to drive the fixed pulley 53 to rotate. When the fixed pulley 53 rotates clockwise, the movable window 23 moves upward, and when the fixed pulley 53 rotates counterclockwise, the movable window 23 moves downward. Specifically, the driving member 54 uses an electric motor as a core power source, and is linked to a signal of the main control unit to dynamically adjust the position of the movable window 23 according to the aerosol concentration in the first disinfection room 11. When the air in the first disinfection room 11 is When the sol concentration sensor 41 detects an increase in concentration, the main control unit sends a control signal, the driving member 54 starts and drives the fixed pulley 53 at the bottom to rotate in a clockwise direction through the connecting mechanism. During this process, the fixed pulley 53 changes the tension distribution of the steel cable 51, so that the top of the steel cable 51 generates an upward traction force, thereby pushing the movable pulley 52 to slide upward with the movable window 23, reducing the opening area between the transition space and the first disinfection room 11, thereby enhancing the upward guiding effect of the airflow on the aerosol, and ensuring that the aerosol can be quickly transferred to the second disinfection room 12.
[0048] When the aerosol concentration drops below the safe range, the main control unit instructs the driving component 54 to run in the opposite direction through a signal, and the bottom fixed pulley 53 rotates counterclockwise. At this time, the tension at the top of the steel cable 51 gradually decreases, and the tension at the bottom increases, prompting the movable pulley 52 to drive the movable window 23 to slide downward, increasing the opening area, and restoring the air circulation between the transition space and the first disinfection room 11 to normal, thereby maintaining the balance and stability of the entire system.
[0049] In summary, through the linkage with the main control unit, the driving component 54 can dynamically adjust the operating parameters according to the real-time data to ensure the accuracy of the adjustment of the moving window 23; secondly, the use of a high-efficiency motor to drive the fixed pulley 53 not only improves the response speed of the moving window 23, but also reduces the energy consumption of the system; in addition, the forward and reverse rotation design of the fixed pulley 53 simplifies the mechanical conduction path of the moving window 23 moving up and down, and improves the stability of the system operation.
[0050] In one embodiment, it also includes a first air pipe 6, the air outlet of the first air pipe 6 is connected to the negative pressure component 43, and the air inlet is arranged at the bottom of the first disinfection room 11. It should be noted that the design of the first air pipe 6 is intended to optimize the separation and transfer of pollutants in the first disinfection room 11. Through the suction effect formed by the negative pressure component 43 at the air outlet of the first air pipe 6, the airflow in the first disinfection room 11 can be guided to flow toward the air inlet of the air pipe, thereby realizing efficient collection of dust in the bottom area, making full use of the high density of dust, so that it naturally settles to the bottom under the action of gravity and is further discharged through the negative pressure system.
[0051] When the first disinfection room 11 starts to operate, the negative pressure component 43 is activated, and a continuous low-pressure area is generated in the first air pipe 6, forcing air to enter from the air inlet at the bottom of the first disinfection room 11. The formation of air flow not only helps to quickly remove dust from the first disinfection room 11, but also effectively avoids the phenomenon of dust being suspended again due to air flow disturbance. For example, in the process of medical waste treatment, particulate dust containing pathogens usually gathers at the bottom of the first disinfection room 11. At this time, the first air pipe 6 uses negative pressure to direct the dust to a special collection device, thereby reducing the risk of pollution spread.
[0052] In one embodiment, the air inlet of the second air pipe 42 is located at the upper part of the second disinfection room 12 and is higher than the air inlet of the first air pipe 6. It should be noted that the air inlet of the second air pipe 42 is located at the upper part of the second disinfection room 12. This arrangement takes advantage of the low density and easy suspension of aerosol particles to ensure that under the negative pressure of the second disinfection room 12, the aerosol can be quickly guided into the air pipe for centralized treatment. In contrast, the air inlet of the first air pipe 6 is located at the bottom of the first disinfection room 11 and is specifically used to guide dust particles. The height difference between the two air inlets enables the system to perform graded treatment according to the physical properties of the pollutants, avoiding interference and cross-diffusion of different types of pollutants.
[0053] During actual operation, after the first disinfection room 11 completes the preliminary separation of dust and aerosol, the aerosol enters the second disinfection room 12 with the airflow, and due to its low density characteristics, it gathers in the upper area of the second disinfection room 12. The negative pressure component 43 generates attraction through the air inlet of the second air pipe 42, and guides the aerosol into the second air pipe 42 to complete the further transfer and processing of the aerosol. At the same time, since the air inlet of the first air pipe 6 is located at a lower position, the system ensures the independence of the dust treatment path, and the aerosol transfer process will not be disturbed by airflow disturbance.
[0054] In one embodiment, the cabin body 1 is also provided with a second partition 32, which is used to form a third disinfection room 13 on the side of the second disinfection room 12 relative to the first disinfection room 11; the bottom of the first fan blade 21 is a locking connection, which is used to transfer the medical waste that has been dust-treated in the first disinfection room 11 to the second disinfection room 12, and a second transfer door is provided between the second disinfection room 12 and the third disinfection room 13, which is used to transfer the medical waste that has been treated in the second disinfection room 12 to the third disinfection room 13. The third disinfection room 13 is provided with an ultraviolet lamp for further disinfection of medical waste. In this embodiment, the medical waste storage cabin is further divided into the third disinfection room 13 by adding a second partition 32 to further divide one side of the second disinfection room 12, thereby realizing a multi-stage pollutant treatment process with clear divisions and optimized functions. The design of the second partition 32 not only provides an independent space for deep disinfection of medical waste, but also improves the safety and systematicness of the pollutant treatment process.
[0055] A locking connection structure is adopted at the bottom of the first fan blade 21, which is used to transfer the medical waste to the second disinfection room 12 in an orderly manner after the dust treatment is completed in the first disinfection room 11.
[0056] When the medical waste arrives at the second disinfection room 12, its main function is to complete the centralized collection and treatment of aerosols. The negative pressure design on the top of the second disinfection room 12 can quickly guide the aerosols to be discharged through the second air pipe 42, and at the same time provide a clean air environment for subsequent transfer. In order to further improve the waste treatment efficiency, the second disinfection room 12 is connected to the third disinfection room 13 through the second transfer door. The third disinfection room 13 is the final link in the medical waste treatment process, which is specially used for deep disinfection of medical waste after preliminary treatment in the second disinfection room 12. The third disinfection room 13 is equipped with a high-efficiency ultraviolet lamp. The ultraviolet light it emits is optimized in wavelength and can accurately destroy the DNA or RNA structure of pathogens and quickly reduce their biological activity.
[0057] In one embodiment, the negative pressure in the second disinfection room 12 is greater than that in the first disinfection room 11 and the third disinfection room 13. Specifically, the negative pressure in the second disinfection room 12 is generated by a high-performance negative pressure component 43. The negative pressure is regulated to make the internal pressure lower than that in the first disinfection room 11 and the third disinfection room 13, thereby ensuring the unidirectionality of air flow, that is, the gas can enter the second disinfection room 12 from the first disinfection room 11, and enter the third disinfection room 13 from the second disinfection room 12 without countercurrent or reflux. During operation, when the aerosol enters the first disinfection room 11, the gas in the second disinfection room 12 is discharged from the second disinfection room 12 to the third disinfection room 13. When the first disinfection room 11 is separated and enters the second disinfection room 12, the aerosol particles will be quickly attracted into the second disinfection room 12 due to the higher negative pressure in the second disinfection room 12, thus preventing them from being retained or diffused in the first disinfection room 11; in addition, this negative pressure gradient also ensures that the separation and treatment paths of dust and aerosol in the two areas do not intersect, thereby improving the efficiency of pollutant treatment. For example, the dust generated in the first disinfection room 11 will sink to the bottom collection device, while the aerosol will enter the second disinfection room 12 along the top path through the negative pressure.
[0058] When medical waste enters the second disinfection room 12, the negative pressure system further plays a role, quickly separating the aerosols that may be attached to the waste through strong adsorption, and guiding them into the processing equipment through the second air pipe 42, which not only significantly reduces the aerosol concentration in the second disinfection room 12, but also provides a clean environment for the subsequent treatment of medical waste.
[0059] The medical waste entering the third disinfection room 13 can be transported to the ultraviolet disinfection area for deep disinfection at a stable flow rate because the negative pressure in the third disinfection room 13 is lower than that in the second disinfection room 12. The setting of the pressure gradient is particularly important in this process, which not only avoids the aerosol in the second disinfection room 12 from flowing back to the third disinfection room 13, but also ensures the stability of the air flow in the third disinfection room 13, which helps the ultraviolet lamp to thoroughly disinfect the pollutants on the surface and inside of the medical waste.
