Description

Technical Field

[0001] This utility model relates to the field of biosafety technology, and in particular to a disinfection device. Background Technology

[0002] Based on GB 50073-2013 Cleanroom Design Code, GB50447-2008 Technical Specification for Laboratory Animal Facilities Construction, and GB14925-2024 Specification for Laboratory Animal Environment and Facilities, ordinary environmental test samples must undergo strict purification and sterilization procedures before entering biological laboratory areas with purification requirements (hereinafter collectively referred to as purification areas).

[0003] Currently, conventional test samples entering the cleanroom require personnel to carry them through a pass-through window for 15-30 minutes of sterilization before they can be retrieved for experimental use. After sampling or testing, the samples are carried out by the personnel through a buffer zone in the waste disposal area. Current pass-through windows primarily achieve sterilization through ultraviolet light and hydrogen peroxide, but these methods only disinfect the exposed surfaces of the samples, not the bottom. Furthermore, the pass-through windows typically use mechanical automatic doors (i.e., mechanical clamping), which are not ideal for sealing.

[0024] In this embodiment, a vertical disinfection device is used as an example. Please refer to the attached document. Figure 1 This disinfection equipment, as an improved transfer window structure, is mainly located between the non-clean area and the clean area. It purifies and sterilizes test samples entering the clean area, ensuring the cleanliness of the samples themselves and reducing cross-contamination. The main disinfection structure 1 has inflatable doors 3 installed at both the front and rear ends. These inflatable doors 3 facilitate the transfer of test samples. The main disinfection structure 1 has a door frame 2 at the location of the inflatable door 3. The inflatable door 3 is positioned on top of the door frame 2 and includes multiple interconnected elastic airbags and an air injection / extraction device. This device is connected to both the inflatable door 3 and the inflatable sealing body 30. When the air injection / extraction device inflates or deflates the inflatable door 3, it extends downwards and retracts upwards accordingly, adjusting the opening and closing mechanism of the inflatable door 3. Please refer to the appendix. Figure 5To further improve the sealing between the inflatable door leaf 3 and the door frame 2, the edge of the inflatable door leaf 3 is designed as a groove 28, and a matching mating block 29 is provided on the door frame 2 at the position opposite to the groove 28. To ensure a full fit between the groove 28 and the mating block 29, an inflatable sealing body 30 is provided on the inner surface of the groove 28. This inflatable sealing body 30 can be a silicone air ring. When the inflatable door leaf 3 is in the closed state, and the air injection / extraction device inflates the inflatable sealing body 30, the inflatable door leaf 3 and the door frame 2 are sealed together. A sealed body is formed between the main disinfection structures 1. It should be noted that, in order to achieve individual inflation or deflation control of the two inflatable door panels 3 at the front and rear ends, and the two inflatable sealed bodies 30 at the front and rear ends, this application also provides four separate pipelines. These four separate pipelines are connected one-to-one with the two inflatable door panels 3 at the front and rear ends, and the two inflatable sealed bodies 30 at the front and rear ends. Each of the four separate pipelines is equipped with a control valve to achieve individual control of each pipeline. Simultaneously, the air injection / extraction device may include… The air pump 17 and motor 18 are used to drive the operation of the air pump 17 to achieve gas compression and propulsion. Specifically, the motor 18 can rotate forward and reverse under the control of the external controller 10, thereby enabling the air pump 17 to inflate or inhale. For example, when the air pump 17 inhales, it drives the inflatable door 3 at the front end of the disinfection main structure 1 to retract upward, thus opening the inflatable door 3 at the front end of the disinfection main structure 1. Furthermore, this application also provides an external controller 10, which is connected to the motor 18, The inlet valve 12, outlet valve 16, chemical pump 13, lifting cylinder 9, first air inlet valve 4, second air inlet valve 19, air supply fan 20, exhaust valve 6, and exhaust fan 8 are electrically connected to control the motor 18, inlet valve 12, outlet valve 16, chemical pump 13, lifting cylinder 9, first air inlet valve 4, second air inlet valve 19, air supply fan 20, exhaust valve 6, and exhaust fan 8. Additionally, to facilitate observation of the purification and sterilization status of the test sample within the main sterilization structure 1, other methods can be employed. A transparent, inflatable door leaf 3 is made of (ethylene-tetrafluoroethylene copolymer) material to improve practicality.

[0025] In this embodiment, please refer to the appendix. Figure 2 and attached Figure 4The disinfection main structure 1 has an immersion disinfection area at its inner bottom for immersing the bottom of the test sample. The immersion disinfection area is a hydrogen peroxide solution immersion tank. The side of the hydrogen peroxide solution immersion tank is provided with an inlet pipe 11 and a drain pipe 15 that penetrate the disinfection main structure 1. The inlet pipe 11 and the drain pipe 15 are respectively provided with an inlet valve 12 and a drain valve 16. The inlet end of the inlet valve 12 is connected to the output end of the chemical pump 13, and the input end of the chemical pump 13 is connected to the storage tank 14. The disinfection main structure 1 has a lifting structure 27 inside for placing the test sample and moving the test sample vertically. The top of the disinfection main structure 1 is provided with a lifting cylinder 9. The output end of the lifting cylinder 9 is connected to a piston rod 23 that penetrates the disinfection main structure 1. The lower end of the piston rod 23 is connected to the lifting structure 27. The lifting structure 27 is a plate structure with through holes 21.

[0026] In this embodiment, by setting a hydrogen peroxide solution immersion tank and a lifting structure 27 inside the disinfection main structure 1, and setting a lifting cylinder 9 and a piston rod 23 connected to the output end of the lifting cylinder 9 at the top of the disinfection main structure 1, the lifting structure 27 and the test sample placed on the lifting structure 27 can be vertically lifted and lowered by the piston rod 23 under the action of the lifting cylinder 9, so as to realize the immersion treatment and draining treatment of the test sample; the specific working principle is as follows: after the test sample is placed on the lifting structure 27, in the first immersion disinfection stage, the lifting cylinder 9 drives the lifting structure 27 to move vertically downward by the piston rod 23. By setting the lifting structure 27 as a plate structure with through holes 21, the test sample can be vertically lifted and lowered. The bottom of the sample is fully immersed in hydrogen peroxide solution to disinfect the bottom area of ​​the sample. The immersion depth of the sample can be flexibly adjusted according to the actual situation and is not limited here. In addition, by setting up inlet pipe 11, outlet pipe 15, inlet valve 12, outlet valve 16, chemical pump 13 and storage tank 14, the hydrogen peroxide solution in storage tank 14 can be transported to the hydrogen peroxide solution immersion tank through chemical pump 13, inlet valve 12 and inlet pipe 11 to realize the feeding function of hydrogen peroxide solution. At the same time, when it is necessary to replace the hydrogen peroxide solution in the hydrogen peroxide solution immersion tank, the hydrogen peroxide solution in the hydrogen peroxide solution immersion tank can be discharged by opening inlet valve 12 to realize the discharge function of hydrogen peroxide solution.

[0027] In this embodiment, the top of the disinfection main structure 1 is provided with a hydrogen peroxide vapor inlet and an exhaust outlet 22. Please refer to the attached document. Figure 2 and attached Figure 3The inner wall of the disinfection main structure 1 is provided with a longitudinal ventilation channel 25 and a transverse ventilation channel 26 extending laterally along the axial direction and side wall of the disinfection main structure 1, respectively. One end of the transverse ventilation channel 26 is connected to the longitudinal ventilation channel 25, and the other end is connected to the inner cavity of the disinfection main structure 1. The longitudinal ventilation channel 25 is provided with an air inlet 24 connecting to the outside of the disinfection main structure 1. A first air inlet valve 4 is provided at the hydrogen peroxide vapor inlet, and the air inlet of the first air inlet valve 4 is connected to the hydrogen peroxide vapor supply device 5. A second air inlet valve 19 is provided at the air inlet 24, and the air inlet of the second air inlet valve 19 is connected to the output end of the air supply fan 20. An exhaust valve 6 is provided at the exhaust outlet 22, and the air outlet of the exhaust valve 6 is connected to the input end of the exhaust fan 8. An air filter 7 is provided at the connection between the second air inlet valve 19 and the air supply fan 20, and between the exhaust valve 6 and the exhaust fan 8.

[0028] In this embodiment, a hydrogen peroxide vapor inlet, a first air inlet valve 4, and a hydrogen peroxide vapor supply device 5 are installed at the top of the main disinfection structure 1. After the first immersion disinfection stage is completed, the hydrogen peroxide vapor in the hydrogen peroxide vapor supply device 5 is transported into the main disinfection structure 1 through the hydrogen peroxide vapor inlet, so that hydrogen peroxide vapor is released at the hydrogen peroxide vapor inlet to simultaneously fumigate the test sample, such as for 30 minutes, to achieve the second fumigation and immersion disinfection stage. It should be noted that when transporting hydrogen peroxide vapor into the main disinfection structure 1, a high concentration of hydrogen peroxide vapor can be transported in a short time (such as releasing hydrogen peroxide vapor with a concentration of 1% within 1 minute), and simultaneous fumigation treatment can be achieved under this state to prevent the pressure inside the main disinfection structure 1 from becoming too high and exploding. After the second fumigation and immersion disinfection stage is completed, the lifting cylinder 9 drives the lifting structure 27 through the piston rod 23. The device moves vertically upwards. By setting the lifting structure 27 as a plate structure with through holes 21, the hydrogen peroxide solution soaked at the bottom of the test sample can be drained. Through the cooperation of the exhaust port 22, air inlet 24, longitudinal ventilation channel 25, transverse ventilation channel 26, second air inlet valve 19, air supply fan 20, exhaust valve 6, exhaust fan 8, and air filter 7, purified external air can enter the disinfection main structure 1 through the air inlet 24, longitudinal ventilation channel 25, and transverse ventilation channel 26 to achieve air shower treatment of the test sample. This not only effectively improves the purification and sterilization effect of the test sample but also improves the cleanliness inside the disinfection equipment. At the same time, the exhaust valve 6 and exhaust fan 8 are opened to promptly remove the gas inside the disinfection main structure 1 to complete the third air shower stage. In addition, by setting the air filter 7, the input air and output gas can be filtered to achieve the purification conditions for biosafety protection.

[0029] In this embodiment, in order to meet the requirement of air shower uniformity, a plurality of horizontal ventilation channels 26 are arranged side by side on the inner wall of the disinfection main structure 1, and the spacing between two adjacent horizontal ventilation channels 26 is equal from the bottom to the top of the disinfection main structure 1, so as to improve the airflow uniformity during air intake.

[0030] In this embodiment, the working principle of the disinfection equipment is as follows: the disinfection equipment is placed between the non-clean area and the clean area. The operation of the motor 18 is controlled by the external controller 10. The motor 18 drives the air pump 17 to discharge the gas in the inflatable sealing body 30 at the front end of the disinfection main structure 1, and the inflatable door 3 at the front end of the disinfection main structure 1 is opened. Then, the test sample is placed on the lifting structure 27, and the inflatable door 3 at the front end of the disinfection main structure 1 is closed, and the inflatable sealing body 30 at the front end of the disinfection main structure 1 is filled with gas. At this point, a seal is formed between the inflatable door 3 and the main disinfection structure 1. In the first immersion disinfection stage, the lifting cylinder 9 drives the lifting structure 27 to move vertically downward via the piston rod 23. By setting the lifting structure 27 as a plate structure with through holes 21, the bottom of the test sample can be fully immersed in hydrogen peroxide solution, achieving the purpose of disinfecting the bottom area of ​​the test sample. After the first immersion disinfection stage is completed, the hydrogen peroxide vapor in the hydrogen peroxide vapor supply device 5 is delivered to the disinfection unit through the hydrogen peroxide vapor inlet. Inside the main structure 1, hydrogen peroxide vapor is released at the hydrogen peroxide vapor inlet to simultaneously fumigate the test sample, achieving the second fumigation and immersion disinfection stage. After the second fumigation and immersion disinfection stage is completed, the lifting cylinder 9 drives the lifting structure 27 vertically upward via the piston rod 23. By setting the lifting structure 27 as a plate structure with through holes 21, the hydrogen peroxide solution immersed at the bottom of the test sample can be drained. At the same time, the second air inlet valve 19 and the air supply fan 20 are opened to allow the external air to pass through... Purified air enters the interior of the disinfection main structure 1 through the air inlet 24, the longitudinal ventilation channel 25, and the transverse ventilation channel 26 to perform air shower treatment on the test samples. Simultaneously, the exhaust valve 6 and the exhaust fan 8 are opened to promptly remove the gas inside the disinfection main structure 1, thus completing the third air shower stage. Finally, the gas inside the inflatable sealing body 30 at the rear end of the disinfection main structure 1 is discharged, and the inflatable door 3 at the rear end of the disinfection main structure 1 is opened, thereby completing the functions of purifying, sterilizing, and transferring the test samples that have entered the purification area.

[0031] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications or substitutions should be considered within the protection scope of the present invention.
