Abstract
Description
Technical Field
[0001] This application relates to the field of biomedical device sterilization, and in particular to a device sterilization transfer cabinet suitable for biological clean environments. Background Technology
[0002] Sterilization of biomedical devices is primarily to ensure they reach a sterile state before use, preventing cross-infection and protecting the safety of patients and healthcare workers. Sterilization effectively kills all microorganisms on the medical device, preventing them from becoming sources of infection. This also complies with medical regulations, especially for medical devices that enter human tissues or sterile organs. Sterilization reduces the risk of infection for patients during surgery or treatment, and decreases medical disputes and accidents.
[0003] Most existing technologies employ moist heat sterilization, whose sterilization apparatus consists of an inner tank, an outer shell, a control system, and a piping system. The inner tank, acting as a steam container, comprises a heater, a tray, and a water tank, ensuring ample and even steam distribution. The outer shell, made of stainless steel, provides robust protection and excellent sealing to prevent steam leakage. The control system integrates sensors for temperature and pressure, precisely regulating various parameters during the sterilization process, such as temperature, pressure, and time, to guarantee sterilization effectiveness. The piping system connects the inner tank to the outside and includes steam input pipes and temperature sensors, responsible for introducing steam and real-time monitoring of sterilization parameters. These structures work together to ensure the moist heat sterilization apparatus efficiently and safely completes the sterilization of medical devices, which are then allowed to air dry naturally after sterilization.
[0004] Regarding the aforementioned technologies, staff need to place instruments on a tray. When performing moist heat sterilization, the sterilization effect on the surface of the instrument in contact with the tray may be weak. Furthermore, natural air drying is time-consuming, reducing the efficiency of overall instrument sterilization. Additionally, when the internal structure of the instrument is complex, the sterilization vapor accumulated inside the instrument may be difficult to dry. Therefore, improvements are needed. Summary of the Invention
[0005] In order to reduce blind spots during instrument sterilization, improve the overall efficiency of instrument sterilization, and enhance the sterilization and drying effect on the internal structure of instruments, this application provides an instrument sterilization transfer cabinet suitable for biological clean environments.
[0006] This application provides a sterilization transfer cabinet for medical devices suitable for biological clean environments, which adopts the following technical solution:
[0007] A sterilization transfer cabinet for instruments suitable for a biological clean environment includes a cabinet body, wherein a first partition, a second partition, a third partition and a fourth partition are spaced apart inside the cabinet body, wherein the second partition and the third partition are both disposed between the first partition and the fourth partition, and the second partition is disposed between the first partition and the third partition;
[0008] The side of the first partition away from the second partition and the inner wall of the box form a feeding chamber; the first partition, the second partition and the inner wall of the box form a disinfection chamber; the second partition, the third partition and the inner wall of the box form a drying chamber; the third partition, the fourth partition and the inner wall of the box form a testing chamber; and the fourth partition and the inner wall of the box form a discharge chamber.
[0009] The box is also equipped with a first conveyor belt, a second conveyor belt, a third conveyor belt and a fourth conveyor belt. The first conveyor belt is partially located in the feeding hopper and partially passes through the first partition and is located in the disinfection hopper. The second conveyor belt is partially located in the disinfection hopper and partially passes through the second partition and is located in the drying hopper. The third conveyor belt is partially located in the drying hopper and partially passes through the third partition and is located in the testing hopper. The fourth conveyor belt is partially located in the testing hopper and partially passes through the fourth partition and is located in the discharge hopper.
[0010] The area between the first conveyor belt and the second conveyor belt is a disinfection station for disinfecting instruments; the area between the second conveyor belt and the third conveyor belt is a drying station for drying the disinfected instruments; and the area between the third conveyor belt and the fourth conveyor belt is a detection station for detecting whether the instruments have been completely dried.
[0011] The housing is provided with a first moving mechanism for clamping and moving instruments within the housing and rotating in one direction at the disinfection station, the drying station, and the testing station, and a second moving mechanism for rotating in the other direction. The first moving mechanism and the second moving mechanism are arranged perpendicular to each other, and the first moving mechanism is arranged in conjunction with the second moving mechanism.
[0012] By adopting the above technical solution, the instruments are placed on the first conveyor belt, which is then activated to transport them into the disinfection chamber. Under the action of the first or second moving mechanism, the instruments are transported to the disinfection station for two-way rotational disinfection, thereby reducing blind spots in the disinfection process. When the instruments have internal structures, this also improves the rinsing effect inside the instruments. The two-way clamping switching avoids blind spots caused by the clamping blocks. After disinfection, the instruments need to be dried. The first or second moving mechanism transports the instruments to the second conveyor belt, which then conveys them to the drying chamber, where they are dried under the action of the first or second moving mechanism. The instruments are transported to the drying station for two-way rotation drying. The rotation also generates a centrifugal effect, which centrifuges out the disinfectant solution accumulated inside the instruments, thereby improving the drying efficiency and effect. After drying, the instruments are transported to the third conveyor belt by the first or second moving mechanism. The third conveyor belt then transports the instruments to the testing chamber, where they are transported to the testing station by the first or second moving mechanism for residual rinsing solution detection. This determines whether the instruments have been completely dried. If residual rinsing solution is detected, the above operation is repeated until no residual rinsing solution is detected, indicating that rinsing and drying are complete, thus improving the disinfection and sterilization effect of the instruments.
[0013] Optionally, the first moving mechanism includes a first moving component and a second moving component, which are symmetrically arranged and the first moving component is arranged with the second moving component. The first moving component includes a drive motor, a lead screw, a sliding block, and a clamping rotation structure. A moving groove is provided on the housing, and the sliding block is slidably disposed in the moving groove. The drive motor is disposed on the side wall of the housing. One end of the lead screw is connected to the output shaft of the drive motor, and the other end is rotatably disposed on the housing. The sliding block is threadedly connected to the lead screw. The clamping rotation structure is disposed on the sliding block and is used to clamp and rotate the instrument in two directions.
[0014] By adopting the above technical solution, the drive motor is started, which drives the lead screw to rotate. Since there is a threaded connection between the lead screw and the sliding block, the sliding block can be moved, thereby moving the clamping and rotating component structure on the moving block. The first moving component and the second moving component are arranged symmetrically, so the instrument can be clamped and fixed by the clamping and rotating component, and the instrument can be rotated while moving. The first moving mechanism and the second moving mechanism are arranged to realize the clamping and rotation of the instrument in two directions, thereby reducing the sterilization dead angle of the instrument. When there is an internal structure of the instrument, it can also improve the rinsing and sterilization effect of the instrument. The clamping switching in two directions can avoid the clamping dead angle generated when the clamping block clamps the instrument. When the instrument rotates, it can also generate a centrifugal effect, so the disinfectant accumulated inside the instrument can be centrifuged out, thereby improving the drying efficiency and drying effect when drying the instrument.
[0015] Optionally, the clamping and rotating structure includes an electric telescopic rod, a multi-stage telescopic sleeve, a toothed ring, a clamping block, and a rack. The fixed end of the electric telescopic rod is disposed on the sliding block, and the telescopic end of the electric telescopic rod passes through the sliding block and is disposed in the housing. The fixed end of the multi-stage telescopic sleeve is rotatably disposed on the side of the sliding block away from the drive motor. The telescopic end of the electric telescopic rod is rotatably connected to the end of the innermost sleeve of the multi-stage telescopic sleeve away from the electric telescopic rod. The clamping block is disposed on the end of the innermost sleeve of the multi-stage telescopic sleeve away from the electric telescopic rod. The rack is disposed in the housing, and the toothed ring is disposed on the outermost sleeve of the multi-stage telescopic sleeve, and the rack and the toothed ring mesh with each other.
[0016] By adopting the above technical solution, since the rack and toothed ring mesh with each other, the fixed end of the multi-stage telescopic sleeve is rotatably mounted on the sliding block. Therefore, when the sliding block drives the multi-stage telescopic sleeve to move, the multi-stage telescopic sleeve can be rotated. The electric telescopic rod is activated. Since the telescopic end of the electric telescopic rod is rotatably connected to the end of the innermost sleeve of the multi-stage telescopic sleeve away from the electric telescopic rod, the extension of the telescopic end of the electric telescopic rod can drive the extension of the multi-stage telescopic sleeve, thereby achieving the clamping of the instrument. The clamping of the instrument is completed by the clamping block, and the rotation of the multi-stage telescopic sleeve is achieved by the toothed ring and rack, thus realizing the clamping and rotation of the instrument.
[0017] Optionally, the sliding block is provided with sealing blocks at both ends along the length of the box, and the sealing blocks are slidably disposed in the moving groove, and the length of the sealing blocks is greater than that of the disinfection chamber, the drying chamber and the testing chamber.
[0018] By adopting the above technical solution, the sealing block can seal the disinfection chamber when the clamping block is located inside the disinfection chamber, thereby improving the sealing effect of the disinfection chamber. It can also seal the drying chamber when the clamping block is located inside the drying chamber, thereby improving the sealing effect of the drying chamber. This reduces the leakage of high-temperature steam and high-temperature drying gas, and reduces their impact on the working environment of the staff.
[0019] Optionally, the inner wall of the disinfection chamber is provided with multiple sets of water outlet strips, each with multiple nozzles for spraying high-temperature disinfection steam containing fluorescein. A movable chamber is formed within each water outlet strip, and a movable plate is slidably disposed within the movable chamber. A cleaning needle is disposed on the side of the movable plate near the nozzles, and a spring is disposed on the side of the movable plate away from the cleaning needles. An air inlet pipe is provided on the chamber body, connecting to the side of the movable plate near the nozzles. The drying chamber is configured similarly to the disinfection chamber, and the nozzles in the drying chamber are used to spray high-temperature drying airflow. The inner wall of the detection chamber is provided with multiple sets of ultraviolet lamps for emitting residual fluorescein, and a photosensitive sensor for detecting the emitted residual fluorescein.
[0020] By adopting the above technical solution, when high-temperature steam is input into the side of the moving plate near the nozzle through the air inlet pipe in the disinfection chamber, the increased air pressure on the side of the moving plate near the nozzle causes the moving plate to move away from the nozzle. At this time, the spring is compressed, the cleaning needle separates from the nozzle, and the high-temperature disinfecting gas sprayed from the nozzle disinfects the instruments at the disinfection station. When the input of high-temperature steam to the side of the moving plate near the nozzle stops, the spring extends, and the cleaning needle extends into the nozzle, thus avoiding nozzle clogging after prolonged use. Similarly, the instruments at the drying station are dried through the nozzle in the drying chamber. After drying, the instruments are moved to the detection station for detection by the first or second moving mechanism. The ultraviolet lamp is turned on. If the photosensor detects a fluorescent spot, it means that the drying is incomplete or the cleaning is not thorough enough. The cleaning and drying process is repeated until no fluorescent spot can be detected.
[0021] Optionally, a liquid outlet pipe is provided at the bottom of the box, which is connected to the bottom of the disinfection chamber and the bottom of the drying chamber respectively. The liquid outlet pipe is arranged in a tortuous manner and is provided with multiple heat dissipation fins. A pump is provided at the other end of the liquid outlet pipe.
[0022] By adopting the above technical solution, the extraction pump can be started to condense and recover the high-temperature disinfection steam in the disinfection chamber, as well as to recover and reuse the high-temperature disinfection steam that has been condensed in the disinfection chamber. It can also recover and reuse the disinfection steam that has been dried and evaporated on the instruments in the drying chamber, thereby improving the utilization rate of disinfectant and fluorescein.
[0023] Optionally, the first partition has a transmission port, a gate is provided on the transmission port, and an installation strip is provided above the gate. The first partition also has an electric lifting rod, the telescopic end of which is connected to the installation strip. The second, third, and fourth partitions are arranged with the first partition. The first conveyor belt has horizontal bars spaced apart. When the gate is closed, the end that contacts the first conveyor belt is engaged between two adjacent sets of horizontal bars. The second, third, and fourth conveyor belts are arranged with the first conveyor belt.
[0024] By adopting the above technical solution, when the electric lifting rod is started, the telescopic end of the electric lifting rod will drive the mounting strip to rise and fall, thereby realizing the raising and lowering of the gate. When the gate is closed, the end that contacts the first conveyor belt is engaged between two adjacent sets of crossbars, thereby further improving the sealing effect between the gate and the first, second, third and fourth conveyor belts.
[0025] Optionally, the movable slot is provided with an accordion cover.
[0026] By adopting the above technical solutions, the bellows cover can further improve the overall sealing performance of the enclosure, thereby further reducing the impact of high-temperature steam and high-temperature drying gas on the working environment of the staff.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. Start the first conveyor belt to transport the instruments into the disinfection chamber. Under the action of the first or second moving mechanism, the instruments are transported to the disinfection station for two-way rotation disinfection, thereby reducing the disinfection dead angles of the instruments. When there is an internal structure of the instrument, it can also improve the rinsing effect inside the instrument. The two-way clamping switching can avoid the clamping dead angles generated when the clamping block clamps the instrument.
[0029] 2. The instruments are transported to the second conveyor belt by the first or second moving mechanism, and then to the drying chamber by the second conveyor belt. Under the action of the first or second moving mechanism, the instruments are transported to the drying station for two-way rotation drying. When the instruments rotate, centrifugal effect is also generated, so the disinfectant accumulated inside the instruments can be centrifuged and thrown out, thereby improving the drying efficiency and drying effect when drying the instruments.
[0030] 3. After drying, the instruments are transported to the third conveyor belt by the first or second moving mechanism. The third conveyor belt then transports the instruments to the testing chamber. Under the action of the first or second moving mechanism, the instruments are transported to the testing station for residual rinsing solution detection. This determines whether the instruments have been completely dried. If residual rinsing solution is detected, the above operation is repeated until no residual rinsing solution is detected, which means that rinsing and drying are complete, thus improving the disinfection and sterilization effect of the instruments.
[0031] 4. When high-temperature steam is introduced into the side of the moving plate near the nozzle through the air inlet pipe inside the disinfection chamber, the increased air pressure on the side of the moving plate near the nozzle will cause the moving plate to move away from the nozzle. At this time, the spring is compressed, the cleaning needle separates from the nozzle, and the high-temperature disinfecting gas sprayed from the nozzle disinfects the instruments on the disinfection station. When the high-temperature steam is stopped being introduced into the side of the moving plate near the nozzle, the spring extends, and the cleaning needle extends into the nozzle, thereby avoiding nozzle clogging after prolonged use.

[0041] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0042] This application discloses an instrument sterilization transfer cabinet suitable for biological clean environments, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4 A sterilization transfer cabinet for instruments suitable for biological clean environments includes a cabinet body 1. A first partition 11, a second partition 12, a third partition 13, and a fourth partition 14 are spaced apart inside the cabinet body 1. The second partition 12 and the third partition 13 are both located between the first partition 11 and the fourth partition 14, and the second partition 12 is located between the first partition 11 and the third partition 13. The side of the first partition 11 away from the second partition 12 and the inner wall of the cabinet body 1 form a feeding chamber 15. The first partition 11, the second partition 12, and the inner wall of the cabinet body 1 form a disinfection chamber 16. The second partition 12, the third partition 13, and the inner wall of the cabinet body 1 form a drying chamber 17. The third partition 13, the fourth partition 14, and the inner wall of the cabinet body 1 form a testing chamber 18. The fourth partition 14 and the inner wall of the cabinet body 1 form a discharging chamber 19.
[0043] The housing 1 is also equipped with a first conveyor belt 2, a second conveyor belt 3, a third conveyor belt 4, and a fourth conveyor belt 5. The first conveyor belt 2 is partially located within the feeding hopper 15 and partially penetrates the first partition 11 within the disinfection chamber 16. The second conveyor belt 3 is partially located within the disinfection chamber 16 and partially penetrates the second partition 12 within the drying chamber 17. The third conveyor belt 4 is partially located within the drying chamber 17 and partially penetrates the third partition 13 within the testing chamber 18. The fourth conveyor belt 5 is partially located within the testing chamber 18 and partially penetrates the fourth partition 11. 4 is set inside the discharge hopper 19; the area between the first conveyor belt 2 and the second conveyor belt 3 is a disinfection station for disinfecting instruments, the area between the second conveyor belt 3 and the third conveyor belt 4 is a drying station for drying the disinfected instruments, and the area between the third conveyor belt 4 and the fourth conveyor belt 5 is a detection station for detecting whether the instruments have been completely dried; the box 1 is provided with a first moving mechanism 6 and a second moving mechanism 7, which are arranged perpendicularly to each other, and the first moving mechanism 6 is arranged with the second moving mechanism 7.
[0044] The instruments are placed on the first conveyor belt 2 and started. The first conveyor belt 2 transports the instruments into the disinfection chamber 16. Under the action of the first moving mechanism 6 or the second moving mechanism 7, the instruments are transported to the disinfection station for two-way rotation disinfection, thereby reducing disinfection dead angles. When there are internal structures on the instruments, it can also improve the rinsing effect inside the instruments. The two-way clamping switching can avoid the clamping dead angles generated when the clamping block 6144 clamps the instruments. After disinfection, the instruments also need to be dried. The first moving mechanism 6 or the second moving mechanism 7 transports the instruments to the second conveyor belt 3, which then transports them to the drying chamber 17. Under the action of the first moving mechanism 6 or the second moving mechanism 7, the instruments are dried. The instruments are transported to the drying station for two-way rotation drying. The rotation also generates a centrifugal effect, which centrifuges out the disinfectant solution accumulated inside the instruments, thereby improving the drying efficiency and effect. After drying, the instruments are transported to the third conveyor belt 4 by the first moving mechanism 6 or the second moving mechanism 7. The third conveyor belt 4 then transports the instruments to the testing chamber 18, where they are transported to the testing station by the first moving mechanism 6 or the second moving mechanism 7 for residual rinsing solution detection. This determines whether the instruments have been completely dried. If residual rinsing solution is detected, the above operation is repeated until no residual rinsing solution is detected, indicating that rinsing and drying are complete, thus improving the disinfection and sterilization effect of the instruments.
[0045] Reference Figure 5The first moving mechanism 6 includes a first moving component 61 and a second moving component 62, which are symmetrically arranged, with the first moving component 61 and the second moving component 62 being arranged together. The first moving component 61 includes a drive motor 611, a lead screw 612, a sliding block 613, and a clamping rotation structure 614. A moving groove is provided on the housing 1, and the sliding block 613 is slidably disposed in the moving groove. The drive motor 611 is disposed on the side wall of the housing 1. One end of the lead screw 612 is connected to the output shaft of the drive motor 611, and the other end is rotatably disposed on the housing 1. The sliding block 613 is threadedly connected to the lead screw 612. The clamping rotation structure 614 is disposed on the sliding block 613 and is used to clamp and rotate the instrument in two directions. An accordion cover 10 is provided on the moving groove.
[0046] The drive motor 611 is started, which drives the lead screw 612 to rotate. Since the lead screw 612 and the sliding block 613 are threadedly connected, the sliding block 613 can be moved, thereby moving the clamping and rotating component structure on the moving block. The first moving component 61 and the second moving component 62 are set together and are symmetrically arranged. Therefore, the instrument can be clamped and fixed by the clamping and rotating component, and the instrument can be rotated while moving. The first moving mechanism 6 and the second moving mechanism 7 are set together to realize the clamping and rotating of the instrument in two directions, thereby reducing the disinfection dead angle of the instrument. When there is a structure inside the instrument, the rinsing effect inside the instrument can also be improved. The clamping switching in two directions can avoid the clamping dead angle generated when the clamping block 6144 clamps the instrument. When the instrument rotates, a centrifugal effect is also generated, so the disinfectant accumulated inside the instrument can be centrifuged out, thereby improving the drying efficiency and drying effect when drying the instrument. The bellows cover 10 can further improve the overall sealing performance of the box 1, thereby further reducing the impact of high temperature steam and high temperature drying gas on the working environment of the staff.
[0047] Reference Figure 5The clamping and rotating structure 614 includes an electric telescopic rod 6141, a multi-stage telescopic sleeve 6142, a gear ring 6143, a clamping block 6144, and a rack 6145. The fixed end of the electric telescopic rod 6141 is mounted on the sliding block 613, and the telescopic end of the electric telescopic rod 6141 passes through the sliding block 613 and is disposed inside the housing 1. The fixed end of the multi-stage telescopic sleeve 6142 is rotatably mounted on the side of the sliding block 613 away from the drive motor 611. The telescopic end of the telescopic rod 6141 is rotatably connected to the end of the innermost sleeve of the multi-stage telescopic sleeve 6142 away from the electric telescopic rod 6141. The clamping block 6144 is set on the end of the innermost sleeve of the multi-stage telescopic sleeve 6142 away from the electric telescopic rod 6141. The rack 6145 is set in the housing 1. The toothed ring 6143 is set on the outermost sleeve of the multi-stage telescopic sleeve 6142, and the rack 6145 and the toothed ring 6143 mesh with each other.
[0048] Since the rack 6145 and the toothed ring 6143 mesh with each other, and the fixed end of the multi-stage telescopic sleeve 6142 is rotatably mounted on the sliding block 613, the sliding block 613 can rotate the multi-stage telescopic sleeve 6142 when it moves. This activates the electric telescopic rod 6141. Because the telescopic end of the electric telescopic rod 6141 is rotatably connected to the end of the innermost sleeve of the multi-stage telescopic sleeve 6142 furthest from the electric telescopic rod 6141, the extension of the telescopic end of the electric telescopic rod 6141 can extend the multi-stage telescopic sleeve 6142, thereby clamping the instrument. The clamping block 6144 completes the clamping of the instrument, and the toothed ring 6143 and the rack 6145 achieve the rotation of the multi-stage telescopic sleeve 6142, thus realizing the clamping and rotation of the instrument.
[0049] Reference Figure 5 The sliding block 613 has sealing blocks 615 at both ends along the length of the housing 1, and the sealing blocks 615 are slidably disposed in the moving groove. The length of the sealing blocks 615 is greater than that of the disinfection chamber 16, the drying chamber 17, and the testing chamber 18. The sealing blocks 615 can seal the disinfection chamber 16 when the clamping block 6144 is located in the disinfection chamber 16, improving the sealing effect of the disinfection chamber 16, and can also seal the drying chamber 17 when the clamping block 6144 is located in the drying chamber 17, improving the sealing effect of the drying chamber 17, thereby reducing the leakage of high-temperature steam and high-temperature drying gas and reducing their impact on the working environment of the staff.
[0050] The inner wall of the disinfection chamber 16 is provided with multiple sets of water outlet strips 161, and multiple nozzles 162 for spraying high-temperature disinfection steam containing fluorescein are provided on the water outlet strips 161. A movable chamber is opened in the water outlet strips 161, and a movable plate 163 is slidably arranged in the movable chamber. A cleaning needle 164 is provided on the side of the movable plate 163 near the nozzle 162, and a spring 165 is provided on the side of the movable plate 163 away from the cleaning needle 164. An air inlet pipe 166 is provided on the housing 1, and the air inlet pipe 166 is connected to the side of the movable plate 163 near the nozzle 162. The drying chamber 17 is arranged in the same way as the disinfection chamber 16. The nozzles 162 in the drying chamber 17 are used to spray high-temperature drying air. The inner wall of the detection chamber 18 is provided with multiple sets of ultraviolet lamps 181 for emitting residual fluorescein, and a photosensitive sensor 182 for detecting the emitted residual fluorescein.
[0051] Reference Figure 6 and Figure 7 When high-temperature steam is introduced into the side of the moving plate 163 near the nozzle 162 through the air inlet pipe 166 inside the disinfection chamber 16, the increased air pressure on the side of the moving plate 163 near the nozzle 162 causes the moving plate 163 to move away from the nozzle 162. At this time, the spring 165 is compressed, the cleaning needle 164 separates from the nozzle 162, and the high-temperature disinfecting gas ejected from the nozzle 162 disinfects the instruments at the disinfection station. When the high-temperature steam is stopped being introduced into the side of the moving plate 163 near the nozzle 162, the spring 165 extends. The cleaning needle 164 extends into the nozzle 162 to prevent the nozzle 162 from becoming clogged after prolonged use. Similarly, the nozzle 162 dries the instruments at the drying station in the drying chamber 17. After drying, the instruments are moved to the testing station by the first moving mechanism 6 or the second moving mechanism 7 for testing. The ultraviolet lamp 181 is turned on. If the photosensor 182 detects a fluorescent spot, it means that the drying is incomplete or the cleaning is not thorough enough. The cleaning and drying process is repeated until no fluorescent spot can be detected.
[0052] A liquid outlet pipe 8 is installed at the bottom of the housing 1, which connects to the bottom of the disinfection chamber 16 and the bottom of the drying chamber 17. The liquid outlet pipe 8 is designed in a tortuous manner and is equipped with multiple heat dissipation fins 81. A pump 82 is installed at the other end of the liquid outlet pipe 8. When the pump 82 is started, it can condense and recover the high-temperature disinfection steam in the disinfection chamber 16, and recover and reuse the high-temperature disinfection steam that has been condensed in the disinfection chamber 16. It can also recover and reuse the disinfection steam that has been evaporated and dried on the instruments in the drying chamber 17, thereby improving the utilization rate of disinfectant and fluorescein.
[0053] Reference Figure 6The first partition 11 has a transmission port 9, on which a gate 91 is installed. An installation strip 92 is installed above the gate 91. An electric lifting rod 93 is also installed on the first partition 11, with its telescopic end connected to the installation strip 92. The second partition 12, third partition 13, and fourth partition 14 are configured similarly to the first partition 11. Horizontal bars 94 are spaced apart on the first conveyor belt 2. When the gate 91 is closed, the end in contact with the first conveyor belt 2 engages between two adjacent sets of horizontal bars 94. The second conveyor belt 3, third conveyor belt 4, and fourth conveyor belt 5 are configured similarly to the first conveyor belt 2. Activating the electric lifting rod 93 causes its telescopic end to move the installation strip 92 up and down, thus raising and lowering the gate 91. When the gate 91 is closed, the end in contact with the first conveyor belt 2 engages between two adjacent sets of horizontal bars 94, further improving the sealing effect between the gate 91 and the first, second, third, fourth, and fourth conveyor belts.
[0054] The implementation principle of an instrument sterilization transfer cabinet suitable for biological clean environments according to an embodiment of this application is as follows:
[0055] When instruments need to be sterilized: the instruments are placed on the first conveyor belt 2, the first conveyor belt 2 is started, and the instruments are transported into the sterilization chamber 16 via the first conveyor belt 2. The nozzles 162 in the sterilization chamber 16 spray a disinfectant solution containing fluorescein. The drive motor 611 is started, and the start motor drives the lead screw 612 to rotate. Since the lead screw 612 and the sliding block 613 are threadedly connected, the sliding block 613 can be moved. Since the toothed ring 6143 and the rack 6145 are meshed with each other, When the sliding block 613 moves the multi-stage telescopic sleeve 6142, it can rotate the multi-stage telescopic sleeve 6142 and activate the electric telescopic rod 6141. Therefore, the extension of the telescopic end of the electric telescopic rod 6141 can drive the extension of the multi-stage telescopic sleeve 6142, thereby clamping the instrument. The clamping block 6144 completes the clamping of the instrument, and the toothed ring 6143 and the rack 6145 realize the rotation of the multi-stage telescopic sleeve 6142, so as to realize the clamping, rotation and sterilization of the instrument.
[0056] When instruments need to be dried: the instruments are transported to the second conveyor belt 3 by the first moving mechanism 6 or the second moving mechanism 7, and then conveyed to the drying chamber 17 by the second conveyor belt 3. The nozzles 162 in the drying chamber 17 spray high-temperature gas, repeating the operation during disinfection. The rotating clamp can centrifugally throw out the disinfectant solution accumulated inside the instruments, thereby improving the drying efficiency and drying effect when drying instruments.
[0057] When it is necessary to test the drying of instruments: the instruments are transported to the third conveyor belt 4 by the first moving mechanism 6 or the second moving mechanism 7, and then transported to the testing chamber 18 by the third conveyor belt 4. The operation of disinfection or drying is repeated. If the photosensor 182 in the testing chamber 18 detects the presence of fluorescent spots under the irradiation of the ultraviolet lamp 181, it means that the drying is incomplete or the cleaning is not thorough enough. The cleaning and drying are repeated until no fluorescent spots can be detected.
