Description

Technical Field

[0001] The present invention relates to the field of sterilization technology, and in particular to a medical waste sterilizer based on the Internet of Things and a control method thereof. Background Art

[0002] The working principle of a steam sterilizer is to thoroughly sterilize bacteria through high-temperature steam and the large amount of latent heat it releases. When the steam is in full contact with contaminated items, it condenses into water and releases a large amount of latent heat, causing the temperature to rise rapidly, thereby achieving the sterilization effect. Specifically, a steam sterilization tank uses steam and pressure to liquefy the sterilizer, and allows it to penetrate into the surface of items through infusion, soaking, etc., thereby inactivating the germs therein.

[0003] At present, when sterilizing medical waste, the existing conventional pressure steam sterilizer is not suitable for in-situ disinfection of small medical institutions and hospital departments. First of all, the in-situ disinfection treatment method is difficult for environmental regulatory departments to supervise and does not have the Internet of Things function. When the environmental regulatory department conducts supervision, it is usually necessary to conduct on-site sampling, which leads to the occupation of a large amount of human resources, low supervision efficiency, and lack of implementation function. Secondly, when the medical waste treated by high temperature is depressurized, it releases a strong odor, which not only pollutes the surrounding environment, but also easily causes discomfort to the operators. In addition, due to the limited space occupied by waste treatment, the odor is not easy to dissipate, which causes the odor to stay for a long time, causing discomfort to the operators and affecting the smooth progress of the work. Summary of the invention

[0016] 2. At the same time, the sterilization tank is heated by the heating element, so that the liquefied water evaporates again and enters the condensation tank, carrying the odor on the sterilization tank and solid waste into the condensation tank, drying the solid waste, greatly reducing the odor in the sterilization tank and weakening the impact of the odor on the surrounding environment.

[0017] 3. At the same time, establishing communication through the data sharing interactive platform and the sterilizer terminal can not only realize the orderly progress of the sterilization process, but also facilitate the supervision of the environmental regulatory department, greatly save human resources, and help improve the efficiency of relevant departments.

[0018] 4. Through the set gas storage box, gas can be continuously input into the gas storage box through the first cylinder and the first piston during the process of steam entering the sterilization tank. After sterilization and drying are completed, the gas storage box can be connected with the sterilization tank by moving the sealing member, so that the stored gas is discharged into the sterilization tank, and the odor in the sterilization tank is removed again to prevent the existence of a small amount of odor components in the sterilization tank after the pressure between the condensation tank and the sterilization tank is stabilized, resulting in the discomfort of the operator caused by the internal odor when the sealing cover is opened.

[0019] 5. By utilizing the movement of the second cylinder, the second piston and the pusher at the same time, the opening timing of the blocking member can be controlled, thereby controlling the timing of releasing the gas inside the gas storage box. After sterilization and drying are completed, the gas is released to achieve a better effect of removing odors, effectively increasing the stability and effectiveness of the device when in use.

[0020] 6. By disassembling the connected storage parts, solid waste can be accommodated. After sterilization and drying, the solid waste can be taken out at one time, which increases the convenience during operation.

[0021] 7.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1 At present, when sterilizing medical waste, the existing conventional pressure steam sterilizer is not suitable for in-situ disinfection of small medical institutions and hospital departments. First of all, the in-situ disinfection treatment method is difficult for environmental regulatory departments to supervise and does not have the Internet of Things function. When the environmental regulatory department conducts supervision, it is usually necessary to conduct on-site sampling, which leads to the occupation of a large amount of human resources, low supervision efficiency, and lack of implementation function. Secondly, when the medical waste treated by high temperature is depressurized, it releases a strong odor, which not only pollutes the surrounding environment, but also easily causes discomfort to the operators. In addition, due to the limited space occupied by waste treatment, the odor is not easy to dissipate, which causes the odor to stay for a long time, causing discomfort to the operators and affecting the smooth progress of the work.

[0039] In order to solve the above technical problems, referring to the accompanying drawings of the specification Figures 1 to 12 The first embodiment of the present invention provides a medical waste sterilizer based on the Internet of Things, including a sterilization tank 1, on which an inflation tube 101 is arranged, and also includes a sealing component 3, a water storage tank 4 and a condensation tank 9. The sealing component 3 includes a storage component 301 arranged in the sterilization tank 1, and the water storage tank 4 is connected to the sterilization tank 1 through an electromagnetic pump 5, a first electromagnetic valve 11 and a steam generator 6. The sterilization tank 1 and the condensation tank 9 are both connected to a vacuum pump 7 through a second electromagnetic valve 12. The air outlet end of the vacuum pump 7 is connected to a high-efficiency filter 8, and a heating element 10 is arranged on the outside of the sterilization tank 1.

[0040] The sterilization tank 1 is connected to the vacuum pump 7 through the discharge pipe and the second solenoid valve 12, and the condensation tank 9 is connected to the discharge pipe corresponding to the sterilization tank 1 through the second solenoid valve 12 and the discharge pipe, and the second solenoid valve 12 corresponding to the sterilization tank 1 can simultaneously control the opening and closing of the corresponding discharge pipes of the sterilization tank 1 and the condensation tank 9. A temperature sensor for detecting the temperature inside the sterilization tank 1 is arranged in the sterilization tank 1, which is not shown in the figure.

[0041] During specific use, the sterilizer is equipped with an electronic scale, a control terminal and a data sharing interactive platform, which are not shown in the figure. The sealing cover 102 on the sterilization tank 1 is opened, and the solid medical waste is placed in the storage part 301, and then the sealing cover 102 is closed. A sealing gasket is provided in the sealing cover 102, which is not shown in the figure. It is used to ensure the sealing inside the sterilization tank 1 and enable the control terminal of the sterilizer to establish communication with the data sharing interactive platform, which is not shown in the figure. The solid waste is weighed by the electronic scale equipped with the sterilizer, and the weight information of each type of waste is input into the control terminal of the sterilizer through the human-computer interaction interface to confirm the weight information of each type of waste, and then the two second solenoid valves 12 are opened through the control terminal. The condensation tank 9 and the sterilization tank 1 are both connected to the vacuum pump 7. The vacuum pump 7 is turned on to evacuate the inside of the condensation tank 9 and the sterilization tank 1. The exhausted gas is filtered by the high-efficiency filter 8 to become harmless gas, and then the two second solenoid valves 12 are closed through the control terminal.

[0042] Then the control terminal opens the first solenoid valve 11, so that the water in the water tank 4 is discharged to the steam generator 6, and the water is converted into steam and enters the sterilization tank 1. The steam in the high temperature state and the large amount of latent heat released by it thoroughly sterilize the bacteria. When the steam is in full contact with the contaminated items, it condenses into water and releases a large amount of latent heat, which rapidly increases the temperature, thereby achieving the sterilization effect. The temperature sensor can detect the temperature in the sterilization tank 1 and send a signal to the control terminal. The pressure gauge 103 can detect the pressure in the sterilization tank 1 and send a signal to the control terminal. After the solid waste in the sterilization tank 1 is sterilized for a period of time, the temperature and pressure in the sterilization tank 1 are prevented from being excessively high and causing adverse effects. After the sterilization purpose is achieved, the control terminal closes the steam generator 6 and the first solenoid valve 11.

[0043] The second solenoid valve 12 corresponding to the condensation tank 9 is connected to the sterilization tank 1 at the same time, and then the control terminal opens the second solenoid valve 12 corresponding to the condensation tank 9 to connect the condensation tank 9 with the sterilization tank 1. Since the temperature in the condensation tank 9 is relatively low, the steam is liquefied, and the air pressure in the condensation tank 9 is lower than the air pressure in the sterilization tank 1, so that the steam in the sterilization tank 1 is continuously discharged into the condensation tank 9. The steam discharged from the sterilization tank 1 into the condensation tank 9 can take away a large amount of odor in the sterilization tank 1 to prevent the odor from being too heavy when the sealing cover 102 is opened.

[0044] After the air pressure in the sterilization tank 1 and the condensation tank 9 is stabilized, the control terminal controls the heating element 10 to start, and the heating element 10 heats the sterilization tank 1, so that the liquefied water is converted into steam again and discharged to the condensation tank 9 and liquefied. The steam converted from the condensate in the sterilization tank 1 can take away part of the odor in the sterilization tank 1 and attached to the solid waste during the discharge into the condensation tank 9, and reduce the odor in the sterilization tank 1 when the solid waste is taken out again. After continuous heating for a period of time and completing the drying of the solid waste, the control terminal turns off the heating element 10, and then opens the sealing cover 102 to take the solid waste out of the sterilization tank 1 for treatment. A drain valve is provided at one end of the condensation tank 9, which is not shown in detail in the figure. After the sterilization is completed, the control terminal controls the waste water in the condensation tank 9 to be discharged through the drain valve. The above process is shared with the corresponding regulatory authorities through the data sharing platform.

[0045] The sterilization tank 1, water storage tank 4, electromagnetic pump 5, steam generator 6, vacuum pump 7, high-efficiency filter 8, condensation tank 9, heating element 10, first electromagnetic valve 11 and second electromagnetic valve 12 and their connection methods in the present invention are all prior art and will not be described in detail here.

[0046] Through the sterilization tank 1 and the condensation tank 9, after the medical waste in the sterilization tank 1 is sterilized, the corresponding second solenoid valve 12 can be controlled to open, so that the steam in the sterilization tank 1 carries the odor and is discharged into the condensation tank 9, thereby reducing the odor and transferring the steam. At the same time, the interior of the sterilization tank 1 is heated by the heating element 10, so that the liquefied water evaporates again and enters the condensation tank 9, and at the same time, carries the odor on the sterilization tank 1 and the solid waste and is discharged into the condensation tank 9, thereby drying the solid waste, greatly reducing the odor in the sterilization tank 1, and reducing the impact of the odor on the surrounding environment. At the same time, communication is established between the data sharing interactive platform and the sterilizer terminal, which not only enables the orderly conduct of the sterilization process, but also facilitates the supervision of the environmental regulatory department, greatly saves human resources, and is conducive to improving the work efficiency of relevant departments.

[0047] Embodiment 2 Although the above-mentioned embodiment 1 can reduce the residual odor level in the sterilization tank 1, after the air pressure in the sterilization tank 1 and the condensation tank 9 is stabilized, some odor components will still remain in the sterilization tank 1, resulting in odor still being emitted after opening the sealing cover 102, causing pollution to the surrounding environment. Therefore, it is necessary to perform an impact on the sterilization tank 1 again after the air pressure in the sterilization tank 1 and the condensation tank 9 is stabilized, so as to further reduce the residual odor level in the sterilization tank 1.

[0048] In order to solve the above technical problems, based on the above embodiment 1, referring to the accompanying drawings of the specification Figures 1 to 12It can be obtained that the adopted technical solution includes a sterilization tank 1, on which an air charging pipe 101 is arranged, and also includes an air collecting component 2, the air collecting component 2 includes a first cylinder 201 fixedly arranged in the air charging pipe 101, a first piston 202 is slidably arranged in the first cylinder 201, and an air storage box 203 is arranged on the sterilization tank 1, and the side of the first cylinder 201 away from the first piston 202 can be connected to the air storage box 203 through the air storage pipe 204, and the air storage box 203 is provided with an air injection pipe 205 connected to the sterilization tank 1, which is used to discharge the odor in the sterilization tank 1, and the sterilization tank 1 is disassembled. The first cylinder 201 is connected to a sealing cover 102, on which a pressure gauge 103 is arranged, an air inlet pipe 206 is arranged on the first cylinder 201, a first one-way valve opening toward the first cylinder 201 is arranged in the air inlet pipe 206, a second one-way valve opening toward the side of the air storage box 203 close to the inflation pipe 101 is arranged in the air storage pipe 204, an end of the first piston 202 away from the sterilizing tank 1 extends out of the first cylinder 201 and is fixedly provided with a baffle 218, the baffle 218 is slidably connected to the inflation pipe 101, a second cylinder 208 is fixedly arranged in the sterilizing tank 1, and a sliding valve 218 is arranged in the second cylinder 208. A second piston 209 is provided, and a blocking piece 210 capable of blocking the gas storage pipe 204 is provided in the gas storage box 203. The blocking piece 210 is slidably connected to the gas storage box 203. A limiting groove 211 is provided on the side of the blocking piece 210 close to the second cylinder 208. The end of the second piston 209 away from the first cylinder 201 extends out of the second cylinder 208 and is fixed with a fixing piece 212. A limiting piece 213 capable of being inserted into the limiting groove 211 is provided in the fixing piece 212. The fixing piece 212 is slidably connected to the limiting piece 213. The side of the second cylinder 208 away from the fixing piece 212 is connected to the first cylinder 208. Thermal expansion gas is arranged between the two pistons 209, a sealing plate 214 is slidably arranged in the gas storage box 203, a first elastic member 215 is arranged between the end of the sealing member 210 away from the sealing plate 214 and the gas storage box 203, a second elastic member 216 is arranged between the end of the limiting member 213 away from the sealing member 210 and the fixing member 212, the end of the limiting member 213 close to the sealing plate 214 is an inclined surface, a pushing member 217 capable of contacting the inclined surface of the limiting member 213 is fixedly arranged on the sealing plate 214, and the side of the second cylinder 208 provided with thermal expansion gas contacts the heating member 10.

[0049] During actual use, the gas discharged from the steam generator 6 enters the inflation tube 101, in which an annular groove 104 is provided. A third elastic member is provided between the end of the first piston 202 away from the baffle 218 and the first cylinder 201. The steam pushes the baffle 218 to move toward the first cylinder 201, the third elastic member is compressed, and the baffle 218 pushes the gas through the gas storage tube 204 and is discharged into the upper part of the gas storage box 203.

[0050] Due to the provision of a second one-way valve, the gas can be prevented from flowing back into the inflation tube 101. The sealing plate 214 moves downward to a certain extent under the action of air pressure, so that the gas on the lower side of the sealing plate 214 is compressed. After the baffle 218 moves to a certain position, the steam in the inflation tube 101 begins to be discharged into the sterilization tank 1 through the groove 104, thereby sterilizing the medical waste in the sterilization tank 1.

[0051] Subsequently, under the action of the third elastic member, the first piston 202 moves in the opposite direction and covers the groove 104 again. The first piston 202 draws external gas into the first cylinder 201 through the first one-way valve and the air inlet pipe 206, so that the steam is blocked again. When the steam pressure reaches a certain pressure again, the first piston 202 moves again in the direction close to the sterilization tank 1, and the gas storage box 203 continues to store gas, and the steam is discharged into the sterilization tank 1 again. As the gas pressure in the gas storage box 203 increases, the steam on the side of the baffle 218 away from the first piston 202 can continue to store energy, making the steam pressure larger and larger, thereby overcoming the pressure in the gas storage box 203 and storing the gas in the gas storage box 203.

[0052] According to the description in Example 1, after the sterilization time of each component of the waste is reached, the control terminal controls the steam generator 6 to close, so that the second solenoid valve 12 connecting the condensation tank 9 and the sterilization tank 1 is opened, and then the steam in the sterilization tank 1 is discharged into the condensation tank 9 for liquefaction. After the pressure between the two is stable, the heating element 10 is started to convert the water in the sterilization tank 1 into steam again and enter the condensation tank 9, so as to dry the waste in the sterilization tank 1 and discharge the odor into the condensation tank 9 with the steam.

[0053] At the same time, the heating element 10 heats the hot expansion gas in the second cylinder 208 and gradually expands it. The hot expansion gas drives the fixing element 212 to move downward through the second piston 209, and the fixing element 212 drives the limiting element 213 and the second elastic element 216 to move downward. An exhaust hole is provided on one side of the second cylinder 208, and there will be no resistance when the second piston 209 moves downward. After the limiting element 213 moves downward for a certain distance, the limiting element 213 is inserted into the limiting groove 211 under the action of the second elastic element 216.

[0054] After drying is completed, the heating element 10 is turned off, and the hot expanded gas gradually cools down, and then the second piston 209 drives the fixing element 212 to move upward, and the fixing element 212 drives the blocking element 210 to move upward through the limit element 213, so that the blocking element 210 no longer blocks the gas injection pipe 205, and a fourth elastic element is provided between the sealing plate 214 and the gas storage box 203. Under the action of air pressure and the fourth elastic element, the sealing plate 214 moves upward and pushes the gas into the sterilization tank 1, so that the gas in the sterilization tank 1 is discharged into the condensation tank 9, and the odor in the sterilization tank 1 is removed again.

[0055] Before the sealing plate 214 moves upward to the initial position, the sealing plate 214 drives the pushing member 217 to contact the inclined surface of the limiting member 213. The pushing member 217 pushes the limiting member 213 to move toward the direction close to the sterilization tank 1 via the inclined surface of the limiting member 213. The second elastic member 216 is compressed. Then, under the action of the first elastic member 215, the blocking member 210 moves downward again to a position capable of blocking the gas injection pipe 205.

[0056] By setting the gas storage box 203, during the process of steam entering the sterilization tank 1, gas can be continuously input into the gas storage box 203 through the first cylinder 201 and the first piston 202. After the sterilization and drying are completed, the gas storage box 203 can be connected with the sterilization tank 1 by moving the blocking member 210, so that the stored gas is discharged into the sterilization tank 1, and the odor in the sterilization tank 1 is removed again to prevent the sterilization tank 1 from still having a small amount of odor components after the pressure between the condensation tank 9 and the sterilization tank 1 is stabilized, resulting in excessive internal odor and discomfort to the operator when the sealing cover 102 is opened. At the same time, by using the movement of the second cylinder 208, the second piston 209 and the pushing member 217, the opening timing of the blocking member 210 can be controlled, thereby controlling the timing of releasing the gas inside the gas storage box 203. After the sterilization and drying are completed, the gas is released again to achieve a better effect of removing the odor, effectively increasing the stability and effectiveness of the device when in use.

[0057] Embodiment 3 Although the combination of the above-mentioned embodiment 1 and embodiment 2 can remove most of the odors and dry the waste, in the actual operation process, although the gas storage box 203 stores gas with a volume larger than the volume of the sterilization tank 1 under normal pressure when the gas is compressed, due to the large volume of the sterilization tank 1, the gas dispersion cannot effectively fill the sterilization tank 1. When removing the odor in the sterilization tank 1, there is still a part that cannot be removed, resulting in certain limitations in the effect. Therefore, when sterilizing and removing odors, effective use of space can improve the sterilization rate to a certain extent and achieve a better effect of removing odors.

[0058] In order to solve the above technical problems, based on the above-mentioned embodiment 1 and embodiment 2, referring to the accompanying drawings of the specification Figures 1 to 12It can be obtained that the adopted technical solution includes a sterilization tank 1, and also includes a sealing component 3, the sealing component 3 is arranged inside the sterilization tank 1, and is used to reduce the sterilization space during sterilization and improve the sterilization efficiency. The sealing component 3 includes a storage component 301 arranged in the sterilization tank 1, and a plurality of exhaust grooves 302 are opened on the storage component 301. A support plate 303 is fixed in the sterilization tank 1, and a shielding plate 304 capable of shielding the exhaust grooves 302 is provided on the support plate 303, and a plurality of connecting grooves 304 capable of communicating with the corresponding exhaust grooves 302 are opened on the shielding plate 304. 10. A sliding groove 305 is provided at one end of the support plate 303 near the shielding plate 304, and a plurality of blocking members 306 are fixedly arranged in the sliding groove 305. A plurality of sliding members 307 corresponding to the blocking members 306 are slidably arranged on the shielding plate 304. The sliding members 307 are fixedly connected to the shielding plate 304. A ventilation groove 308 is provided on a blocking member 306 near the lower side of the air storage box 203. The ventilation groove 308 is connected to a chamber formed by the air storage box 203 and one end of the sealing plate 214 away from the blocking member 210 through a ventilation pipe 309.

[0059] When the sealing plate 214 moves downward, the sealing plate 214 pushes the gas at the bottom of the gas storage box 203 to be discharged into the space between the corresponding sliding member 307 and the blocking member 306 through the ventilation groove 308 and the ventilation pipe 309. The ventilation pipe 309 is made of explosion-proof material. The gas pushes the sliding member 307 to slide. The sliding member 307 and the blocking member 306 are intermittently arranged. The sliding member 307 drives the shielding plate 304 to rotate, so that the connecting groove 310 on the shielding plate 304 and the exhaust groove 302 on the storage member 301 are gradually staggered. When the sliding member 307 moves to contact another adjacent blocking member 306, the connecting groove 310 on the shielding plate 304 is no longer connected with the corresponding exhaust groove 302, thereby completing the sealing of the storage member 301.

[0060] As the sealing plate 214 is continuously squeezed, the internal gas is gradually compressed, and the fourth elastic member is compressed. After the sterilization and drying are completed, when the sealing member 210 no longer blocks the gas injection pipe 205, the sealing plate 214 moves upward under the pressure of the lower gas and the action of the fourth elastic member. After the sealing plate 214 moves upward for a certain distance, under the action of the fourth elastic member, the sealing plate 214 sucks the gas between the blocking member 306 of the ventilation pipe 309 and the corresponding sliding member 307 through the ventilation pipe 309 and the ventilation groove 308, so that the sliding member 307 slides in the opposite direction of the sliding groove 305, and the sliding member 307 drives the shielding plate 304 to rotate in the opposite direction, so that the connecting groove 310 is connected with the corresponding exhaust groove 302 again.

[0061] Before the connecting groove 310 is connected with the corresponding exhaust groove 302, the gas in the gas storage box 203 is discharged into the upper enclosed space of the sterilization tank 1 through the gas injection pipe 205. The enclosed space is composed of the storage part 301, the upper part of the sterilization tank 1 and the shielding plate 304, which reduces the sterilization space. Therefore, the gas in the gas storage box 203 only needs to be discharged into the enclosed space to achieve the effect of removing odor, and the enclosed space is smaller than the overall space of the sterilization tank 1, thereby improving the sterilization efficiency and enhancing the effect of removing odor.

[0062] By disassembling the connected storage part 301, solid waste can be accommodated. After sterilization and drying, the solid waste can be conveniently taken out at one time, which increases the convenience during operation. The shielding plate 304 can be rotated under the action of the sliding part 307, so that an independent enclosed space is formed on the upper part of the storage part 301, which reduces the sterilization space, maximizes the utilization of steam, improves the sterilization effect, and makes full use of the gas in the gas storage box 203, which has a better effect on removing odors in a small space.

[0063] Embodiment 4 On the basis of the above embodiment, this embodiment also provides a control method of a medical waste sterilizer based on the Internet of Things, comprising the following steps: S1. Open the sealing cover 102 for loading, then close the sealing cover 102 of the sterilization tank 1, so that the control terminal of the sterilizer establishes communication with the data sharing interactive platform, and the weight of the waste type after weighing by the electronic scale is input into the data sharing interactive platform and the control terminal; S2. The control terminal opens the second solenoid valve 12, and the vacuum pump 7 performs a vacuum operation on the sterilization tank 2 and the condensation tank 9. The vacuumed gas is filtered through the high-efficiency filter 8 and discharged to the outside. After the vacuuming is completed, the second solenoid valve 12 is closed; S3. Open the first solenoid valve 11 and the steam generator 6, so that the water evaporates and enters the sterilization tank 1 to sterilize the medical waste, the steam enters the sterilization tank 1 through the gas filling pipe 101, and the gas is stored in the gas storage box 203 through the first cylinder 201; S4. After the disinfection is completed, the second solenoid valve 12 corresponding to the condensation tank 9 is opened to connect the sterilization tank 1 with the condensation tank 9, so that the air pressure of the sterilization tank 1 and the condensation tank 9 is balanced; S5. Start the heating element 10 and continue to heat the sterilization tank 1. Since the sterilization tank 1 and the condensation tank 9 are under negative pressure at this time, the boiling point of water is very low, and the water on the medical waste will continue to evaporate to the condensation tank 9, thereby completing the drying of the medical waste; S6. After the heating element 10 is turned off, the heat-expanded gas contracts, causing the stopper 213 to drive the blocking member 210 to move upward, and no longer block the gas injection pipe 205, so that the gas in the gas storage box 203 is discharged into the sterilization tank 1, and the odor in the sterilization tank 1 is removed and enters the condensation tank 9; S7. After the drying is completed, the drain valve of the condensation tank 9 is opened, and after completion, the sealing cover 102 is opened, and the entire disinfection process is completed.
