Description

Technical Field

[0001] This invention relates to the field of medical disinfection, and more particularly to a hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer. Background Technology

[0002] Ultrasonic probes carry a large number of bacteria after use, making disinfection crucial. Composed of lenses, charged components, silicone rubber seals, and plastic housings, ultrasonic probes are precision and expensive components in ultrasound diagnostics. They cannot be soaked in disinfectant; only wiping is permitted. This is to prevent lens corrosion, which could lead to liquid leakage into the probe, causing short circuits in the charged components and cracking of the silicone rubber seals and plastic housing, thus shortening the probe's lifespan.

[0003] Hydrogen peroxide is widely used as a disinfectant. However, many hospitals, after ultrasound examinations, often only wipe the ultrasound probe and skin with tissue paper, then perform some low-level disinfection of the probe, or use traditional manual soaking for disinfection. Therefore, as an important medium for pathogen transmission, the ultrasound probe must be provided with a highly efficient and safe disinfection method. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention aims to provide a hydrogen peroxide aerosol disinfection device for ultrasonic probes, which uses an atomizing device to atomize liquid hydrogen peroxide solution into hydrogen peroxide aerosol, and uses the atomized hydrogen peroxide aerosol to disinfect the ultrasonic probe.

The atomizing device atomizes liquid hydrogen peroxide into hydrogen peroxide mist. The decomposition device decomposes and releases residual hydrogen peroxide after disinfection, preventing air pollution and potential harm to humans.

The wire clamp includes a first clamp body and a second clamp body, which are cam-shaped and arranged facing each other. The first and second clamp bodies are provided with wire grooves along their circumference. The wire grooves of the first and second clamp bodies form a clamping portion. The first and second clamp bodies are rotatable and can retract the clamping portion.

[0021] In this technical solution, the wire clamp is used to hold the ultrasonic probe lead wire, so that the ultrasonic probe is suspended in the disinfection cavity, which facilitates the disinfection of the ultrasonic probe by the atomized hydrogen peroxide mist; the ultrasonic probe lead wire is held by using the clamping part and the wire groove.

A silicone heating pad heats the disinfection chamber, raising its temperature and maintaining the Brownian motion of hydrogen peroxide molecules while accelerating their decomposition. This allows the disinfecting agents to act on the surface of the object being disinfected, ensuring effective disinfection. By independently configuring the disinfection chamber, atomizing device, and decomposition device, the disinfection, atomization, and decomposition functions of the hydrogen peroxide mist ultrasonic probe sterilizer can be performed independently.

[0053] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0054] Combined with appendix Figure 1 To be continued Figure 5 As shown, this invention provides a hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer, used for disinfecting ultrasonic probes, comprising: a housing, an atomizing device, a decomposition device, and a reversing device; wherein,

[0055] The box 1 includes a first box 11 and a second box 12. The first box 11 includes a first shell 112, and the space inside the first shell 112 forms a first cavity. The second box 12 includes a second shell 122, and the space inside the second shell 122 forms a second cavity. The first box 1 is provided with a first disinfection cavity shell 21, and the second box 12 is provided with a second disinfection cavity shell 22. The first disinfection cavity shell 21 and the second disinfection cavity shell 22 can be closed to form a disinfection cavity 2. A silicone heating pad 26 is provided on the second disinfection cavity shell 22, and a first through hole 23 is provided on the disinfection cavity 2.

[0056] Atomizing device 3, decomposition device 4, and reversing device 5 are disposed in the second chamber;

[0057] The reversing device 5 is used to switch the connection between the disinfection chamber and the atomizing device and the decomposition device between the disinfection mode and the decomposition mode.

[0058] In the disinfection mode, the atomizing device 3, the reversing device 5, and the first through hole 23 are connected by a pipe. The atomizing device 3 is used to atomize the hydrogen peroxide solution, and the atomized hydrogen peroxide can enter the disinfection chamber 2.

[0059] In the decomposition mode, the decomposition device 4, the reversing device 5, and the first through hole 23 are connected by a pipe. The atomized hydrogen peroxide mist in the disinfection chamber 2 can flow into the decomposition device 4. The decomposition device 4 is used to decompose the residual hydrogen peroxide mist from the disinfection chamber 2 into water and oxygen.

[0060] The first housing 112 and the second housing 122 protect the internal devices. The first cavity and the second cavity house the disinfection cavity 2, the atomizing device 3, the decomposition device 4, and the reversing device 5. The disinfection cavity 2 houses the ultrasonic probe, providing a sealed environment for the atomized hydrogen peroxide to disinfect the ultrasonic probe. The silicone heating pad 26 heats the disinfection cavity 2, raising the temperature inside the cavity to ensure the Brownian motion of the hydrogen peroxide atomization molecules and accelerate the decomposition of hydrogen peroxide molecules, allowing the disinfecting agents to act on the surface of the object being disinfected, thus ensuring the disinfection effect. The atomizing device 3 atomizes liquid hydrogen peroxide into hydrogen peroxide atomization. The decomposition device 4 decomposes and discharges the residual hydrogen peroxide after disinfection, preventing air pollution and potential harm to humans. The reversing device 5 switches between two connection modes: the disinfection cavity 2 connected to the atomizing device 3 and the disinfection cavity 2 connected to the decomposition device 4, thereby guiding the atomized hydrogen peroxide atomization.

[0061] In some implementations, the appendix continues to be combined Figure 3 and attached Figure 5As shown, in some embodiments, the reversing device 5 includes a valve device 54, a first tube 51, a second tube 52, and a third tube 53. The first tube 51 is connected to the disinfection chamber 2 through a first through hole 23, the second tube 52 is connected to the atomizing device 3, and the third tube 53 is connected to the decomposition device 4. In the disinfection mode, the valve device 54 controls the first tube 51 and the second tube 52 to be connected, thereby connecting the atomizing device 3 to the disinfection chamber 2, and introducing the atomized hydrogen peroxide gas from the atomizing device 3 into the disinfection chamber 2. In the decomposition mode, the valve device 54 controls the first tube 51 and the third tube 53 to be connected, thereby connecting the decomposition device 4 to the disinfection chamber 2, and introducing the residual atomized hydrogen peroxide from the disinfection chamber 2 into the decomposition device 4.

[0062] In some embodiments, the first disinfection chamber shell 21 is located on the side closer to where the operator opens the disinfector, and the second disinfection chamber shell 22 is located inside the disinfector. Correspondingly, the atomizing device 3, the decomposition device 4, and the reversing device 5 are also located on the side closer to the second disinfection chamber shell 22. The first through hole 23 is provided on the second disinfection chamber shell 22. Therefore, it is convenient to connect the internal pipelines of the disinfector and to open the disinfector door for the operator, making operation convenient.

[0063] In some embodiments, the first through holes 23 are evenly distributed along the length of the disinfection chamber 2, and can be located on one side edge of the disinfection chamber 2 or symmetrically arranged on two symmetrically arranged edges of the disinfection chamber 2. For example, if the outer shell 22 of the second disinfection chamber is semi-cylindrical or semi-cylindrical, then the first through holes 23 are evenly distributed along the two axial edges of the outer shell 22. Therefore, it can be ensured that the first through holes 23 are located in the middle of the disinfection chamber, ensuring effective communication between the disinfection chamber 2 and the atomizing device 3 or the decomposition device 4, and ensuring efficient input and output of disinfectant. Obviously, the outer shell 22 of the second disinfection chamber is not limited to the above-mentioned semi-cylindrical shape, and can also be set to any other shape that can form a closed disinfection chamber 2 with the outer shell 21 of the first disinfection chamber.

[0064] Continue to combine with the appendix Figure 2 As shown, in some embodiments, the outer shell 22 of the second disinfection chamber is also provided with a second through hole 24, and the decomposition device 4 includes a through hole pipe 43. The second through hole 24 is connected to the decomposition device 4 through the through hole pipe. The second through hole 24 is used to introduce excess atomized hydrogen peroxide solution into the decomposition device 4 through the through hole pipe 43 when hydrogen peroxide mist enters the disinfection chamber 2.

[0065] Continue to combine with the appendix Figure 2As shown, in some embodiments, the second through hole 24 is located at the bottom of the outer shell 22 of the second disinfection chamber. In the disinfection mode, when the atomizing device 3 introduces the atomized hydrogen peroxide mist into the disinfection chamber 2, the pressure inside the disinfection chamber 2 increases, and the gas inside the disinfection chamber 2 is introduced into the decomposition chamber 41 through the second through hole 24.

[0066] Continue to combine with the appendix Figure 3 As shown, in some embodiments, the atomizing device 3 further includes a first gas driving device 33, an atomizing chamber 32, and an atomizer 31. The atomizer 31 is used to atomize the liquid hydrogen peroxide solution. The atomizing chamber 32 is used to store the hydrogen peroxide gas mist atomized by the atomizer 31. The atomizer 31 is disposed on the atomizing chamber 32. The atomizing chamber 32, the first gas driving device 33, and the atomizer 31 are disposed in a second chamber. The atomizer 31 is connected to the atomizing chamber 32, and the atomizing chamber 32 is connected to a second pipe. In the disinfection mode, the first gas driving device 33 is used to drive the atomized hydrogen peroxide gas mist from the atomizing chamber 32 to the disinfection chamber 2 to disinfect the ultrasonic probe.

[0067] Continue to combine with the appendix Figure 6 As shown, in some embodiments, the atomizer 31 includes a liquid level probe, a liquid bottom probe, an atomizer housing 312, and an atomizing plate. The liquid level probe and the liquid bottom probe are disposed inside the atomizer housing 312, and the liquid bottom probe is disposed on the atomizing plate 311. The liquid level probe and the liquid bottom probe are disposed on different horizontal planes. The liquid level probe and the liquid bottom probe are used to measure the liquid level of liquid hydrogen peroxide, thereby determining the amount of liquid hydrogen peroxide used. The liquid hydrogen peroxide solution is on the upper side of the atomizing plate 311. The hydrogen peroxide solution is atomized into hydrogen peroxide gas mist through the atomizing plate 311 and enters the atomizing cavity 32. The atomizer housing 312 is used to load the liquid hydrogen peroxide solution.

[0068] Continue to combine with the appendix Figure 4 As shown, in some embodiments, the decomposition device 4 further includes a second gas driving device 42 and a decomposition chamber 41. The decomposition chamber 41 and the second gas driving device 42 are disposed in the second cavity. The decomposition chamber is connected to a third pipe, and the through-hole pipe is connected to the decomposition chamber. In the decomposition mode, the second gas driving device 42 is used to drive the atomized hydrogen peroxide mist in the disinfection chamber 2 to the decomposition chamber 41, and the decomposition device 4 is used to decompose the residual atomized hydrogen peroxide mist after disinfection.

[0069] In some embodiments, the decomposition device 4 includes a heating element that uses heating to promote the decomposition of hydrogen peroxide into oxygen and water.

[0070] Continue to combine with the appendix Figure 1 Appendix Figure 5 Appendix Figure 11 and attached Figure 12As shown, in some embodiments, the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer further includes a door lock device and a first sensor. The door lock device includes a first lock body 61 and a second lock body 62. The first lock body 61 is disposed in the first housing 112, and the second lock body 62 is disposed in the second housing 122. The door lock device is used to lock the first housing 11 and the second housing 12 when the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer is in operation, thereby forming a sealed space between the first disinfection chamber shell 21 and the second disinfection chamber shell 22 to prevent the atomized hydrogen peroxide aerosol from overflowing. The first sensor is used to detect whether the first lock body 61 and the second lock body 62 are locked.

[0071] Continue to combine with the appendix Figure 11 and attached Figure 12 As shown, in some embodiments, the first lock body 61 includes a first crossbeam 611, which is provided with a first groove 6111 and a first protrusion 6112; the second lock body 62 includes a second crossbeam 621, an ejection device 622, a base 623, and a spring 624. The second crossbeam 621 is rotatably connected to the base 623. The second crossbeam 621 is provided with a second groove 6211, a second protrusion 6212, and a spring connection position 6213. A first sensor is disposed on the second lock body 62. Spring 624 connects the spring link 6213 of the second crossbeam 621 and the base 623. The ejection device 622 includes a base 6221 and an ejection post 6222. The ejection post 6222 is disposed on the base 6221 and is disposed on the lower side of the second crossbeam 621. The first sensor includes an ejection sensor 626 and a crossbeam sensor 625. A limit device 6231 is provided on the base 623 to prevent the second crossbeam 621 from being raised too high.

[0072] The first lock body 61 and the second lock body 62 include a locking mode and an unlocking mode. In the locking mode, the first protrusion 6112 engages with the second groove 6211, and the second protrusion 6212 engages with the first groove 6111. The ejector post 6222 in the ejector device 622 raises the second crossbeam 621, so that the first crossbeam 611 and the second crossbeam 621 are engaged and locked. At this time, the ejector sensor 626 detects that the ejector post 6222 is in the raised state, and the crossbeam sensor 625 detects that the first crossbeam 611 and the second crossbeam 621 are engaged, thus determining that the first lock body 61 and the second lock body 62 have been locked.

[0073] In the unlocking mode, the push-out pin 6222 retracts and returns to its original position, and the spring 624 pulls the second crossbeam 621 to return the second crossbeam 621 to its original position. At this time, the engagement between the first crossbeam 611 and the second crossbeam 621 ends, and the first crossbeam 611 is pulled out from the second lock body 62.

[0074] Continue to combine with the appendix Figure 1 and attached Figure 7As shown, in some embodiments, the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer further includes a wire clamp 7. The housing 1 is provided with a wire clamp receiving part 121. The wire clamp 7 is disposed in the wire clamp receiving part 121. The wire clamp 7 includes a first clamp body 71 and a second clamp body 72. The first clamp body 71 and the second clamp body 72 are arranged facing each other along a first direction x. The first clamp body 71 and the second clamp body 72 are provided with wire grooves 73 along the circumferential direction. The wire grooves 73 of the first clamp body 71 and the second clamp body 72 form a clamping part 74.

[0075] The wire clamp 7 is used to hold the ultrasonic probe, so that the ultrasonic probe is suspended in the disinfection chamber 2, which facilitates the disinfection of the ultrasonic probe by the atomized hydrogen peroxide mist; the wire groove 73 is used to hold the wires on the ultrasonic probe, and the wires on the ultrasonic probe are held by using the clamping part 74 and the wire groove 73.

[0076] Both the first clamp 71 and the second clamp 72 are cam-shaped and rotatably mounted on the outer shell 22 of the second sterilization chamber. When the ultrasound probe is suspended by the wire clamp 7, the first clamp 71 moves along... Figure 7 As shown in Figure A, the second clamp 72 rotates along... Figure 7 As shown in Figure B, when rotated in direction B, the two clamps can rotate until they are against each other and can no longer rotate downwards. Therefore, the first clamp 71 and the second clamp 72 can approach each other. At this time, the wire of the ultrasonic probe passing between the first clamp 71 and the second clamp 72 can be clamped. Moreover, after the ultrasonic probe is clamped, under the gravity of the ultrasonic probe located below the wire, the first clamp 71 and the second clamp 72 can continue to move closer together and press more tightly, thereby achieving a stable clamping effect on the ultrasonic probe.

[0077] The wire clamp 7 is located on the upper part of the side of the second disinfection chamber shell 22 facing the first disinfection chamber shell 21. Correspondingly, receiving grooves for accommodating the wire clamp are provided on the first disinfection chamber shell 21 and the second disinfection chamber shell 22.

[0078] Continue to combine with the appendix Figure 1 and attached Figure 3 As shown, a sealing ring 25 is also provided around the opening of the outer shell 22 of the second disinfection chamber. Above the sealing ring 25, directly below the wire clamp 7, a wire groove 251 is provided in a direction perpendicular to the horizontal plane. When the wire clamp 7 clamps the wire of the ultrasonic probe, the wire of the ultrasonic probe is just embedded in the wire groove 251, which makes it easy to suspend the ultrasonic probe in the disinfection chamber 2. Moreover, by providing the wire groove 251, the wire can be inserted without affecting the sealing of the disinfection chamber 2 due to suspending the ultrasonic probe, and without causing damage to the wire of the ultrasonic probe due to clamping.

[0079] Continue to combine with the appendix Figure 3 Appendix Figure 5 Appendix Figure 8 and attached Figure 9 As shown, in some embodiments, the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer further includes a liquid replenishment device 8 and a control system. The control system includes a traceability system, an operating system, and a storage system. The traceability system includes a card reader 114 and a magnetic card. The liquid replenishment device 8 is disposed on the side wall of the second housing 122. The liquid replenishment device 8 includes a bottle mounting slot 85, a liquid retrieval needle 81, a residual liquid pipeline 82, a second sensor, and a waste liquid box 83. The bottle mounting slot 85 is used to load hydrogen peroxide bottles 86. One end of the liquid retrieval needle 81 is connected to the atomizer 31, and the other end is connected to the hydrogen peroxide bottle 86. The residual liquid pipeline 82 connects the waste liquid box 83 and the bottle mounting slot 85. The second sensor is used to detect whether hydrogen peroxide bottles 86 are loaded in the bottle mounting slot 85. The card reader 114 is disposed on the first housing 11 and is used to read the information of the hydrogen peroxide bottles 86.

[0080] The replenishment device 8 is used to introduce liquid hydrogen peroxide solution from the hydrogen peroxide bottle 86 to the atomizer 31, replenishing the atomizer 31 with liquid hydrogen peroxide solution; the second sensor is used to detect whether the bottle mounting slot 85 is filled with hydrogen peroxide bottle 86, making it easy for operators to identify whether the bottle mounting slot 85 is filled with hydrogen peroxide bottle 86; the waste liquid box 83 is used to collect the residual liquid hydrogen peroxide solution in the bottle mounting slot 85; the liquid retrieval needle 81 is used to remove the liquid hydrogen peroxide solution from the hydrogen peroxide bottle 86 and introduce it into the atomizer 31; the residual liquid pipeline 82 leads the residual liquid hydrogen peroxide solution in the replenishment device 8 to... The waste liquid box 83 prevents hydrogen peroxide solution from flowing into the sterilizer and damaging the equipment when the hydrogen peroxide bottle is replaced. A chip is installed on the hydrogen peroxide bottle to record information about the hydrogen peroxide in the bottle. Before sterilization begins, the card reader 114 reads the information on the chip to confirm whether the quality and concentration of the hydrogen peroxide solution in the bottle meet the requirements, thereby ensuring the sterilization effect. At the same time, before sterilization begins, the card reader 114 reads and records the information of the operator and the ultrasonic probe to be sterilized, which is beneficial for information traceability during sterilization.

[0081] In some implementations, the operator holds a work permit with a magnetic card attached. The magnetic card on the work permit stores the operator's information, such as the operator's name and number. The ultrasonic probe cable also has a magnetic card attached, which stores the ultrasonic probe's information, such as the ultrasonic probe's name and identification number.

[0082] In some embodiments, the card reader 114 is a magnetic card reader 114, and the magnetic card is a chip card, such as an IC card or an ID card. However, the present invention does not limit the model of the card reader 114 and the model of the magnetic card. Here, the card reader 114 is a magnetic card reader 114 and the magnetic card is a chip card for illustrative purposes.

[0083] Before replenishing the hydrogen peroxide solution to the replenishment device 8, the magnetic card on the hydrogen peroxide bottle 86 is read by the card reader 114. The card reader 114 reads the data in the magnetic card on the hydrogen peroxide bottle 86, such as the production date and shelf life of the hydrogen peroxide solution. The operating system compares the information read by the card reader 114 from the magnetic card on the hydrogen peroxide bottle 86 for validity. If the validity comparison result is that the hydrogen peroxide solution is valid, the hydrogen peroxide solution information is stored in the storage system for subsequent traceability of the effectiveness of disinfection information. If the validity comparison result is that the hydrogen peroxide solution is invalid, the operating system displays a prompt message to replace the hydrogen peroxide solution on the control display screen.

[0084] Before disinfection begins, the traceability system retrieves the most recently stored hydrogen peroxide solution information from the storage system and compares its validity. When adding hydrogen peroxide solution to the replenishment device 8, the card reader 114 reads the information from the magnetic card on the hydrogen peroxide bottle 86. The production date of the hydrogen peroxide solution is August 13, 2023, and its shelf life is 12 months. The card reader 114 imports the hydrogen peroxide information into the storage system, and the operating system compares the production date and expiration date of the hydrogen peroxide. If it is expired, the operating system automatically determines that the hydrogen peroxide solution is invalid and will not perform disinfection of the ultrasonic probe, displaying an invalid hydrogen peroxide message on the control screen. If the hydrogen peroxide solution is determined to be within its valid shelf life, disinfection can proceed, and a valid hydrogen peroxide message will be displayed on the control screen. The work permit with the magnetic card and the magnetic card on the ultrasonic probe cable are read by the card reader 114, which retrieves the operator's information and the ultrasonic probe's information, respectively, and stores these information in the storage system for subsequent traceability of disinfection information.

[0085] For example, when adding hydrogen peroxide solution to the replenishment device 8, the card reader 114 reads the information from the magnetic card on the hydrogen peroxide bottle 86. The information includes the production date of the hydrogen peroxide solution as August 13, 2023, and a shelf life of 12 months. The card reader 114 imports this information into the storage system. The operating system compares the production date and expiration date of the hydrogen peroxide for validity. If the solution is expired, the operating system automatically determines that the hydrogen peroxide solution is invalid and will not perform the ultrasonic probe disinfection operation, displaying an invalid hydrogen peroxide message on the control display screen. If the hydrogen peroxide solution is determined to be within its valid shelf life, the disinfection operation can proceed, and a valid hydrogen peroxide message will be displayed on the control display screen.

[0086] Before disinfection begins, card reader 114 reads the information from the magnetic card on the operator's work permit, where the operator's name is A and the number is 123456. Card reader 114 stores the operator's information in the storage system. Card reader 114 also reads the information from the magnetic card on the ultrasonic probe, where the ultrasonic probe's number is 112345. Card reader 114 stores the ultrasonic probe's information in the storage system. The traceability system retrieves the most recently stored hydrogen peroxide solution information in the storage system.

[0087] At the start of disinfection, the traceability system records and stores the start time, such as "8:23 AM on September 15, 2023"; after disinfection is completed, the traceability system records and stores the completion time, such as "8:53 AM on September 15, 2023"; after disinfection is completed, or when it is necessary to obtain information about this disinfection later, the traceability system retrieves and prints this disinfection information from the storage system. The printed information includes the operator's name and number, the ultrasound probe's number, the disinfection start time, and the disinfection end time.

[0088] When the traceability system performs traceability operations on disinfection information, it can retrieve the disinfection information of the ultrasonic probe with that number by using the probe's serial number.

[0089] Continue to combine with the appendix Figure 10 As shown, in some embodiments, the liquid-collecting needle 81 includes a needle body 811 and a pressure equalizing tube 812. The needle body 811 is inserted into the hydrogen peroxide bottle to draw hydrogen peroxide liquid, and the pressure equalizing tube 812 is used to balance the pressure inside the hydrogen peroxide bottle, which is conducive to the full outflow of hydrogen peroxide solution from the hydrogen peroxide bottle.

[0090] Continue to combine with the appendix Figure 3 and attached Figure 5As shown, in some embodiments, the replenishment device 8 further includes a peristaltic pump 84, which is connected to the nebulizer 31 and the liquid collection needle 81. The peristaltic pump 84 provides power to introduce hydrogen peroxide liquid from the hydrogen peroxide bottle into the nebulizer 31.

[0091] Continue to combine with the appendix Figure 4 As shown, in some embodiments, the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer further includes a circuit control component, a relay 91, and an exhaust fan. The circuit control component is disposed in the second cavity. The housing 1 contains a circuit that conducts electrical energy to the operation of each device within the housing, ensuring the normal operation of each device. The circuit control component is used to control the circuit within the housing 1. The exhaust fan includes a first exhaust fan 92 and a second exhaust fan 93. The first exhaust fan 92 is disposed in the first housing 112 of the first housing 11 and is used to reduce the temperature within the first cavity, thereby protecting the devices within the first cavity 113. The second exhaust fan 93 is disposed on the bottom surface of the second housing 12 and is used to reduce the temperature within the second cavity 12, thereby protecting the devices within the second cavity 123. The relay 91 is disposed on the bottom surface of the second housing 122 and is used to protect the circuit control component. The circuit control component is used to control the circuits of each electrical device within the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer. The relay 91 is used to protect the circuit control component and prevent damage to the circuit control component due to overload.

[0092] In some embodiments, the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer also includes a power supply device for supplying power to the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer, and the power supply device is connected to the circuit control components.

[0093] Continue to combine with the appendix Figure 1 and attached Figure 8 As shown, in some embodiments, a handle 113 is provided on the first housing 112, which facilitates the opening and closing of the first housing 112.

[0094] Continue to combine with the appendix Figure 8 As shown, in some embodiments, the hydrogen peroxide aerosol disinfection ultrasonic probe sterilizer also includes a control display screen 111. The control display screen 111 is disposed on the outer surface of the first housing 112. The first sensor, the second sensor, and the card reader 114 are connected to the control display screen 111. The control display screen 111 and the second sensor determine whether a hydrogen peroxide bottle 86 is loaded in the bottle mounting slot 85. The control display screen 111 and the card reader 114 determine whether the hydrogen peroxide solution in the hydrogen peroxide bottle meets the requirements, such as whether the concentration of the hydrogen peroxide solution meets the disinfection requirements and whether the hydrogen peroxide solution has exceeded its shelf life.

[0095] In summary, this invention provides a hydrogen peroxide aerosol disinfection device for ultrasonic probes. The disinfection chamber 2 houses the ultrasonic probe, providing a sealed space for the atomized hydrogen peroxide aerosol to disinfect it. The atomizing device 3 atomizes liquid hydrogen peroxide into hydrogen peroxide aerosol, which facilitates the disinfection of the ultrasonic probe. The decomposition device 4 decomposes and releases residual hydrogen peroxide after disinfection, preventing air pollution and potential harm to humans. The reversing device 5 switches the connection between the disinfection chamber 2 and the atomizing and decomposition devices 4 in disinfection and decomposition modes, guiding the atomized hydrogen peroxide aerosol. By integrating the disinfection and decomposition functions using the atomizing device 3 and the decomposition device 4, the disinfection and decomposition functions are improved, enhancing the effectiveness of hydrogen peroxide aerosol disinfection of ultrasonic probes. The applicability of the head sterilizer; the traceability system reads and records information about operators, ultrasonic probes, and hydrogen peroxide to achieve traceability of the sterilization process; by using a silicone heating pad 26 to heat the sterilization chamber 2, the temperature inside the sterilization chamber 2 is increased, ensuring the activity of Brownian motion of hydrogen peroxide mist molecules and accelerating the decomposition of hydrogen peroxide molecules, so that the disinfecting agents act on the surface of the object being sterilized, thereby ensuring the sterilization effect; by setting the sterilization chamber, atomizing device, and decomposition device independently, it is beneficial to separate and independently perform the sterilization, atomization, and decomposition functions of the hydrogen peroxide mist ultrasonic probe sterilizer. Therefore, after the first sterilization is completed, the residual hydrogen peroxide mist in the sterilization chamber can be introduced into the decomposition device to start the second sterilization work, which greatly improves the overall sterilization efficiency of the hydrogen peroxide mist ultrasonic probe sterilizer.
