Description

Technical Field

[0001] This invention relates to the field of pipette disinfection technology, and in particular to a disinfection liner, a pipette disinfection instrument, and a method for using the disinfection instrument. Background Technology

[0002] Existing technology discloses a contamination-proof storage box for modular pipettes, comprising a storage box body with a rectangular box structure without a left side surface. The modular pipettes are housed inside the storage box body and hung on a rod. The rod is a round rod structure, with its front and rear ends fixedly welded to the front and rear inner walls of the storage box body, respectively. A box lid is provided at the left opening of the storage box body. In this invention, the modular pipettes are stored inside the storage box body, making them less susceptible to external contamination. Furthermore, the interior of the modular pipettes can be cleaned and disinfected using a spray method, resulting in good cleaning and disinfection effects and facilitating future use. In contrast, the existing technology lacks an ultraviolet disinfection method and cannot accommodate the disinfection of large quantities of pipettes. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a disinfection liner that combines spray disinfection and ultraviolet disinfection, suitable for disinfecting large batches of pipettes, a pipette disinfection instrument, and a method for using the disinfection instrument.

[0004] The technical solution of the present invention is: a disinfection liner, comprising a liner body, wherein the interior of the liner body has a cavity for placing a pipette, and multiple rows of support rods for suspending the pipette are installed in the cavity. The top of the liner body has an inlet communicating with the cavity. A mounting base for setting an ultraviolet disinfection lamp is respectively opened on two opposite inner side walls of the liner body. A first spray hole for inputting disinfectant spray and communicating with the cavity and a second spray hole for outputting disinfectant spray and communicating with the cavity are respectively opened on two opposite outer side walls of the liner body.

[0005] The working principle of the above technical solution is as follows:

[0006] By setting up multiple rows of support rods to suspend the pipettes, and designing a mounting base, a first spray hole, and a second spray hole, a combination of spray disinfection and ultraviolet disinfection is achieved, which is suitable for the disinfection of large batches of pipettes.

[0007] In a further technical solution, the support rods are arranged in a stepped manner along the height direction of the inner liner body; wherein, the distance between the ends of two adjacent support rods along the height direction of the inner liner body is 18mm to 30mm, and the distance between two adjacent support rods along the vertical direction of the height of the inner liner body is 100mm to 120mm.

[0008] The stepped arrangement of the support rods avoids interference and collisions between the pipettes.

[0009] In a further technical solution, the support rod has multiple limiting notches that match the pipette along its length, and the projection of the limiting notches along the height direction of the inner liner body is an arc shape.

[0010] The design of the limiting notch allows the pipette to be placed more stably on the support rod.

[0011] In a further technical solution, the sterilization liner also includes a support assembly, a push plate, and an air bladder. The upper surface of the push plate is equipped with multiple rows of support assemblies, the same number as the number of rows of support rods. Each row of support assemblies consists of multiple support parts, each corresponding to a specific suspension position of the pipette on each row of support rods. The four sidewalls of the push plate slide against the inner wall of the cavity of the sterilization liner, and are provided with convex-concave guide structures. An air bladder is provided between the push plate and the inner bottom surface of the cavity of the sterilization liner. The air bladder has an air inlet, and the bottom surface of the liner body has a first air outlet communicating with the air outlet of the air bladder.

[0012] Through the design of the support assembly, push plate, and air bladder, the pipette can be sterilized not only by suspending it on the support rod, but also by placing it on the support assembly.

[0013] To address the aforementioned technical problems, this invention discloses a pipette sterilization instrument, comprising a housing, a lid, an ultraviolet sterilization lamp, and a sterilization inner liner. The housing has a mounting cavity with a top opening, and a matching lid is hinged to the top opening of the housing. Two opposite side walls of the housing each have a third spray hole and a fourth spray hole communicating with the mounting cavity. Two other opposite side walls of the housing each have a power cord hole and a second air supply hole communicating with the mounting cavity. The sterilization inner liner is disposed within the... Inside the installation cavity, there is a height difference between the bottom of the disinfection inner liner and the bottom of the installation cavity. The inner bottom surface of the lid has a sealing protrusion for opening / sealing the top insertion port of the disinfection inner liner. The ultraviolet disinfection lamp is installed on the mounting base inside the disinfection inner liner. The first spray hole on the disinfection inner liner is connected to the third spray hole through a first pipe, and the second spray hole on the disinfection inner liner is connected to the fourth spray hole through a second pipe. The mounting base is provided with a power cord that is connected to an external power source through the power cord hole. The first air outlet is connected to the second air outlet through a third pipe.

[0014] The working principle of the above technical solution is as follows:

[0015] This design, combining a box body, lid, UV disinfection lamp, and inner disinfection liner, integrates spray disinfection and UV disinfection, making it suitable for large-volume pipette disinfection. In use, the externally supplied disinfectant spray flows sequentially through the third spray hole, first pipe, first spray hole, second spray hole, second pipe, and fourth spray hole, achieving a flowing disinfectant spray disinfection of the pipette. This provides better disinfection than simple sealed disinfection. Building upon the aforementioned disinfection, the combination with UV disinfection broadens the disinfection range. Furthermore, externally supplied gas is sequentially injected through the second air inlet, third pipe, first air inlet, and air bladder inlet until the air bladder inflates, pushing the push plate upwards. The upward-moving push plate supports the pipette, causing it to detach from the suspension position on the support rod. Simultaneously, the inflated air bladder seals the first and second spray holes, stopping the external supply of disinfectant spray. This allows the pipette inside the inner cavity to continue being disinfected by the sealed disinfectant spray within the cavity. Firstly, the pipette undergoes a first round of disinfection through both flowing and ultraviolet disinfection. Secondly, by switching the support method (suspension by a support rod and support by a support part), disinfection dead zones of the pipette can be effectively avoided, preventing the pipette from being ineffectively disinfected due to simply being suspended, thus avoiding the risk of incomplete disinfection. Thirdly, by switching the disinfection method, the disinfectant spray disinfection is changed from flowing to sealed static disinfection for a second round of disinfection, mainly targeting the localized disinfection of the suspension contact surface between the pipette and the suspension position. This method also effectively saves disinfectant spray disinfection, thereby avoiding disinfection dead zones of the pipette. Fourthly, sealed static disinfection can also be used for a third and fourth round of disinfection before and after use, targeting the inner cavity of the disinfection liner, the push plate, and the outside of the air bladder (disinfectant spray disinfection enters through the gap between the push plate and the inner cavity).

[0016] In a further technical solution, the insertion port at the top of the disinfection inner liner has a first support edge that bends outward, and the first support edge of the disinfection inner liner is fixedly attached to the second support edge in the upper middle part of the installation cavity.

[0017] Improve the stability between the sterilization liner and the mounting cavity of the box body.

[0018] In a further technical solution, the distance between each of the supporting parts and each corresponding suspension position on the supporting rod is equal. This ensures that all pipettes can be switched synchronously during the process of switching between sterilization while suspended on the supporting rod and sterilization while placed on the supporting assembly.

[0019] To solve the above technical problems, a method for using the pipette sterilization instrument described in any one of the above-mentioned claims is provided, comprising the following steps:

[0020] Open the lid and suspend the pipette on the support rod. Close the lid, ensuring the sealing boss seals the inlet at the top of the inner container. Turn on the external power supply and connect it to the mounting base via the power cord. This activates the UV disinfection lamp mounted on the mounting base, providing UV disinfection for the pipette. Flow the externally supplied disinfectant spray sequentially through the third spray hole, first pipe, first spray hole, second spray hole, second pipe, and fourth spray hole, providing continuous disinfectant spray disinfection for the pipette. When the recorded UV disinfection and disinfectant spray disinfection time reaches the predetermined first disinfection time, inject the externally supplied gas sequentially through the second gas inlet, third pipe, first gas inlet, and air bladder inlet until the air bladder inflates, pushing the push plate upwards. The pipette is then supported by the upward-moving push plate's support. The pipette is moved upwards and detached from the suspension position on the support rod. Simultaneously, the inflated airbag seals the first and second spray holes, and the external supply of disinfectant spray is stopped. This allows the pipette inside the inner cavity to continue being disinfected by the disinfectant spray sealed within the cavity. When the recorded ultraviolet disinfection and disinfectant spray disinfection time of the pipette reaches the predetermined second disinfection time, the external power is turned off, ultraviolet disinfection is stopped, the gas injected into the airbag is extracted, causing the airbag to contract and the push plate to move downwards. This lowers the pipette and resuspends it in the suspension position on the support rod, reconnecting the first and second spray holes. The lid is opened, and the disinfected pipette is removed from the suspension position on the support rod.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention achieves a combination of spray disinfection and ultraviolet disinfection, adaptable to the disinfection of large batches of pipettes, by setting up multiple rows of support rods that suspend the pipettes, and setting up mounting bases, first spray holes and second spray holes.

[0023] 2. In this invention, the stepped arrangement of the support rods avoids mutual interference and collision between the pipettes.

[0024] 3. In this invention, the design of the limiting notch enables the pipette to be placed more stably on the support rod.

[0025] 4. In this invention, through the design of the support assembly, push plate and air bladder, the pipette can not only be suspended on the support rod for disinfection, but also placed on the support assembly for disinfection.

[0026] 5. This invention combines spray disinfection and ultraviolet disinfection through the use of a box body, box lid, ultraviolet disinfection lamp and disinfection inner liner, which is suitable for the disinfection of large batches of pipettes.

[0027] 6. In this invention, the stability between the sterilization inner liner and the mounting cavity of the box body is improved.

[0028] 7. In this invention, during the process of switching between disinfection while the pipette is suspended on the support rod and disinfection while placed on the support assembly, all pipettes can be switched synchronously. Attached Figure Description

[0038] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0039] Example 1:

[0040] like Figure 1 and Figure 2 As shown, a disinfection liner includes an inner liner body 101. The inner liner body 101 has a cavity for placing a pipette. Multiple rows of support rods 102 are installed in the cavity to suspend the pipette. The top of the inner liner body 101 has an inlet 103 communicating with the cavity. A mounting base 104 for setting an ultraviolet disinfection lamp 209 is respectively opened on two opposite inner side walls of the inner liner body. A first spray hole 105 for inputting disinfectant spray and communicating with the cavity and a second spray hole 106 for outputting disinfectant spray and communicating with the cavity are respectively opened on two opposite outer side walls of the inner liner body.

[0041] The working principle of the above technical solution is as follows:

[0042] By setting up multiple rows of support rods 102 to suspend the pipettes, and by setting up mounting bases 104, first spray holes 105 and second spray holes 106, the design achieves a combination of spray disinfection and ultraviolet disinfection, which is suitable for the disinfection of large batches of pipettes.

[0043] In another embodiment, such as Figure 1 and Figure 2 As shown, the support rods 102 are arranged in a stepped manner along the height direction of the inner liner body 101; wherein, the distance between the ends of two adjacent support rods 102 along the height direction of the inner liner body 101 is 18mm to 30mm (e.g., 18mm, 25mm, or 30mm), and the distance between two adjacent support rods 102 along the vertical direction of the height of the inner liner body 101 is 100mm to 120mm (e.g., 100mm, 110mm, or 120mm). This stepped arrangement of the support rods 102 avoids mutual interference and collisions when placing the pipettes.

[0044] In another embodiment, such as Figure 1 and Figure 2As shown, the support rod 102 has multiple limiting notches 107 along its length to match the pipette, and the projection of the limiting notches 107 along the height direction of the inner liner body 101 is arc-shaped. The design of the limiting notches 107 allows the pipette to be placed more stably on the support rod 102.

[0045] In another embodiment, such as Figure 1 and Figure 2 As shown, the sterilization inner liner 10 also includes a support assembly, a push plate 108, and an air bladder 109. The upper surface of the push plate 108 is fitted (e.g., welded) with multiple rows of support assemblies, the same number as the number of rows of support rods 102. Each row of support assemblies consists of multiple support parts 110, each corresponding to a suspension position of the pipette on each row of support rods 102. The four sides of the push plate 108 slide against the inner wall of the cavity of the sterilization inner liner 10, and are provided with convex-concave guide structures. An air bladder 109 is provided between the push plate 108 and the inner bottom surface of the cavity of the sterilization inner liner 10. An air bladder air inlet is provided on the air bladder 109. The bottom surface of the inner liner body 101 is provided with a first air inlet 114 communicating with the air inlet of the air bladder (i.e., the bottom surface of the inner liner body 101 is provided with a through first air inlet 114). Through the design of the support assembly, push plate 108 and airbag 109, the pipette can be sterilized not only by suspending it on the support rod 102, but also by placing it on the support assembly.

[0046] In addition, a circuit channel 112 communicating with the mounting cavity of the box body 201 is provided at the fitting point between the mounting base 104 of the disinfection inner liner 10 and the inner wall surface of the box body 201. Therefore, it will not affect the sealing performance of the disinfection inner liner 10. The power supply line of the external power source passes through the power cable hole 205 on the box body 201, and then connects to the mounting base 104 through the circuit channel 112 to supply power to the ultraviolet disinfection lamp 209 mounted on the mounting base 104. The support part 110 is a cylindrical body with an open top. The inner wall surface of the cylindrical body can be designed to match the outer contour of the bottom of the pipette to better support the pipette. In order to facilitate the disassembly and replacement of the push plate 108 and the air bag 109, the inner bottom surface of the inner cavity can be made into a detachable bottom plate. When it is necessary to disassemble or replace the push plate 108 or the air bag 109, the bottom plate is removed first, and then the push plate 108 or the air bag 109 is disassembled or replaced. The installation is the same. The detachable base plate can be installed on the annular bottom surface of the inner cavity by screws, and a sealing ring is placed between them for sealing. Disassembly is achieved by unscrewing the screws. Since the four sides of the push plate 108 are in surface contact with the four sides of the inner cavity, and there is a convex-concave guiding structure between them (the push plate 108 has guide protrusions around its perimeter, and the inner walls of the inner cavity have guide grooves that match these guide protrusions), the airbag 109 only needs to provide an upward thrust; it is not necessary for the airbag 109 to apply a uniform thrust to the lower surface of the push plate 108.

[0047] Example 2:

[0048] like Figures 3 to 6As shown, to address the aforementioned technical problems, this invention discloses a pipette sterilization instrument 20, comprising a housing 201, a lid 202, an ultraviolet sterilization lamp 209, and a sterilization inner liner 10. The housing 201 has an installation cavity with a top opening. A matching lid 202 is hinged to the top opening of the housing 201. A third spray hole 203 and a fourth spray hole 204 for communicating with the installation cavity are respectively provided on two opposite side walls of the housing 201. A third spray hole 203 for communicating with the installation cavity and a fourth spray hole 204 for communicating with the installation cavity are respectively provided on the other two opposite side walls of the housing. The device includes a power cord hole 205 communicating with the inner cavity and a second air outlet 206 communicating with the mounting cavity; the disinfection inner liner 10 is disposed within the mounting cavity, and there is a height difference between the bottom of the disinfection inner liner 10 and the inner bottom of the mounting cavity; the inner bottom surface of the cover 202 has a sealing boss 207 for opening / sealing the top insertion inlet 103 of the disinfection inner liner 10; the ultraviolet disinfection lamp 209 is disposed on the mounting base 104 inside the disinfection inner liner 10; the first spray hole 105 on the disinfection inner liner 10 is connected to the third spray hole 203 through a first pipe 210; the second spray hole 106 on the disinfection inner liner 10 is connected to the fourth spray hole 204 through a second pipe 211; the mounting base 104 is provided with a power cord connected to an external power source through the power cord hole 205; the first air outlet 114 is connected to the second air outlet 206 through a third pipe 113.

[0049] The working principle of the above technical solution is as follows:

[0050] The device combines spray disinfection and ultraviolet disinfection, and is suitable for the disinfection of large batches of pipettes, through the cooperation of the box body 201, box lid 202, ultraviolet disinfection lamp 209 and disinfection inner liner 10.

[0051] In another embodiment, such as Figures 3 to 6 As shown, the insertion port 103 at the top of the sterilization inner liner 10 has an outwardly bent first support edge 111, and the first support edge 111 of the sterilization inner liner 10 is fixedly attached to the second support edge 208 in the upper middle part of the mounting cavity. This improves the stability between the sterilization inner liner 10 and the mounting cavity of the box body 201.

[0052] In another embodiment, such as Figures 3 to 6 As shown, the distances between each of the support portions 110 and each corresponding suspension position on the support rod are equal. This ensures that all pipettes can be switched synchronously during the process of switching between sterilization while suspended on the support rod 102 and sterilization while placed on the support assembly.

[0053] In addition, all holes and all channel connections are equipped with sealing rings or other sealing components to ensure a tight seal (current conventional technology).

[0054] The operation process of the above technical solution:

[0055] Open the lid 202, suspend the pipette at the suspension position of the support rod 102, and close the lid 202 so that the sealing boss 207 of the lid 202 seals the inlet 103 at the top of the inner liner body 101; turn on the external power supply and connect it to the mounting base 104 through the power cord to turn on the ultraviolet disinfection lamp 209 mounted on the mounting base 104 to disinfect the pipette with ultraviolet light; let the externally supplied disinfectant spray flow sequentially through the third spray hole 203, the first pipe 210, the first spray hole 105, the second spray hole 106, the second pipe 211, and the fourth spray hole 204 to perform flowing disinfectant spray disinfection on the pipette; when the recorded ultraviolet disinfection and disinfectant spray disinfection time of the pipette reaches the predetermined first disinfection time, inject the externally supplied gas sequentially into the second gas inlet 206, the third pipe 113, and the first gas inlet 114. The air supply port of the airbag is inflated until the airbag 109 expands, pushing the push plate 108 upward; the support part 110 of the upward-moving push plate 108 carries the pipette, causing the pipette to move upward and from the support rod 102. The pipette is detached from its suspended position, and the inflated airbag 109 seals the first spray hole 105 and the second spray hole 106, while simultaneously stopping the external supply of disinfectant spray. This allows the pipette inside the inner cavity to continue being disinfected by the disinfectant spray sealed within the cavity. When the recorded ultraviolet disinfection and disinfectant spray disinfection time of the pipette reaches the predetermined second disinfection time, the external power is turned off, ultraviolet disinfection is stopped, the gas injected into the airbag 109 is extracted, causing the airbag 109 to contract and the push plate 108 to move down, allowing the pipette to move down and be resuspended in the suspension position of the support rod 102, thus reconnecting the first spray hole 105 and the second spray hole 106. The box cover 202 is then opened, and the disinfected pipette is removed from the suspension position of the support rod 102.By sequentially allowing externally supplied disinfectant spray to flow through the third spray hole 203, the first pipe 210, the first spray hole 105, the second spray hole 106, the second pipe 211, and the fourth spray hole 204, a flowing disinfectant spray disinfection design is achieved for the pipette, resulting in a better disinfection effect than simple sealing disinfection. Building upon the aforementioned disinfection, ultraviolet disinfection is combined for a wider disinfection range. Furthermore, by sequentially injecting externally supplied gas into the second air inlet 206, the third pipe 113, the first air inlet 114, and the air bladder inlet until the air bladder 109 inflates and pushes the push plate 108 upwards, the pipette is supported by the support portion 110 of the upward-moving push plate 108, causing the pipette to move upwards and detach from the suspension position of the support rod 102. Simultaneously, the inflated air bladder 109 seals the first spray hole 105 and the second spray hole 106, stopping the external supply of disinfectant spray, thus sealing the pipette inside the inner cavity. The sealed disinfectant spray within the inner cavity continues the sealed disinfection process. Firstly, after both flowing and ultraviolet disinfection, the pipette undergoes its first round of disinfection. Secondly, by switching the support method (suspension via support rod 102 and support via support part 110), disinfection dead zones are effectively avoided, preventing incomplete disinfection of the pipette's contact surface due to simply suspending it. Thirdly, by switching the disinfection method, the disinfectant spray disinfection is converted from flowing to sealed static disinfection for a second round of disinfection, primarily targeting the contact surface between the pipette and its suspension position. This method also conserves disinfectant spray, further preventing disinfection dead zones. Fourthly, sealed static disinfection can also disinfect the inner cavity of the inner liner 10, the push plate 108, and the exterior of the airbag 109 (disinfectant spray enters through the gap between the push plate 108 and the inner cavity). The third and fourth rounds of disinfection are carried out before and after use.

[0056] Example 3:

[0057] This invention provides a method for using a pipette sterilizer, comprising the following steps:

[0058] Open the lid and suspend the pipette on the support rod. Close the lid, ensuring the sealing boss seals the inlet at the top of the inner container. Turn on the external power supply and connect it to the mounting base via the power cord. This activates the UV disinfection lamp mounted on the mounting base, providing UV disinfection for the pipette. Flow the externally supplied disinfectant spray sequentially through the third spray hole, first pipe, first spray hole, second spray hole, second pipe, and fourth spray hole, providing continuous disinfectant spray disinfection for the pipette. When the recorded UV disinfection and disinfectant spray disinfection time reaches the predetermined first disinfection time, inject the externally supplied gas sequentially through the second gas inlet, third pipe, first gas inlet, and air bladder inlet until the air bladder inflates, pushing the push plate upwards. The pipette is then supported by the upward-moving push plate's support. The pipette is moved upwards and detached from the suspension position on the support rod. Simultaneously, the inflated airbag seals the first and second spray holes, and the external supply of disinfectant spray is stopped. This allows the pipette inside the inner cavity to continue being disinfected by the disinfectant spray sealed within the cavity. When the recorded ultraviolet disinfection and disinfectant spray disinfection time of the pipette reaches the predetermined second disinfection time, the external power is turned off, ultraviolet disinfection is stopped, the gas injected into the airbag is extracted, causing the airbag to contract and the push plate to move downwards. This lowers the pipette and resuspends it in the suspension position on the support rod, reconnecting the first and second spray holes. The lid is opened, and the disinfected pipette is removed from the suspension position on the support rod.

[0059] The working principle of the above technical solution is as follows:

[0060] By sequentially feeding externally supplied disinfectant spray through a third spray hole, a first pipe, a first spray hole, a second spray hole, a second pipe, and a fourth spray hole, a flow-type disinfectant spray disinfection design is achieved for the pipette, resulting in better disinfection than simple sealed disinfection. Building upon the aforementioned disinfection, ultraviolet disinfection is combined for a wider disinfection range. Furthermore, by sequentially injecting externally supplied gas through a second air inlet, a third pipe, a first air inlet, and an air bladder inlet until the air bladder inflates and pushes the push plate upwards, the pipette is supported by the upward-moving push plate and disengaged from the suspension position of the support rod. Simultaneously, the inflated air bladder seals the first and second spray holes, stopping the external supply of disinfectant spray. This allows the pipette inside the inner cavity to continue being disinfected by the disinfectant spray sealed within the cavity, resulting in a sealed disinfectant spray design. Firstly, the pipette undergoes a first round of disinfection through both flowing and ultraviolet disinfection. Secondly, by switching the support method (suspension by a support rod and support by a support part), disinfection dead zones of the pipette can be effectively avoided. Simply keeping the pipette in a suspended state prevents ineffective disinfection of the contact surface between the pipette and the suspension position, thus avoiding the risk of incomplete disinfection. Thirdly, by switching the disinfection method, the disinfectant spray disinfection is changed from flowing to sealed static disinfection for a second round of disinfection, primarily targeting the localized disinfection of the contact surface between the pipette and the suspension position. This method also effectively conserves disinfectant spray disinfection, thereby avoiding disinfection dead zones of the pipette. Fourthly, sealed static disinfection can also be used for a third and fourth round of disinfection before and after use, targeting the inner cavity of the disinfection liner, the push plate, and the exterior of the air bladder (disinfectant spray disinfection enters through the gap between the push plate and the inner cavity).

[0061] In addition, the disinfection time recorded above can be manually recorded by the operator. There is only one starting point for recording, which is when disinfectant spray is supplied externally. The predetermined first disinfection time and the predetermined second disinfection time can be determined according to actual disinfection needs. For example, the predetermined first disinfection time is 15 minutes and the predetermined second disinfection time is 30 minutes. After the operator manually records the time to the prescribed 15 minutes, the operator injects the externally supplied gas sequentially into the second air inlet, the third pipe, the first air inlet, and the air bag inlet until the air bag inflates and pushes the push plate upward. After the operator manually records the time for the specified 30 minutes, the operator turns off the external power, stops the ultraviolet disinfection, extracts the gas injected into the airbag, causing the airbag to contract and the push plate to move down, thus lowering the pipette and resuspending it in the hanging position on the support rod. This reconnects the first and second spray holes (in this state, the disinfectant spray can be discharged sequentially through the second spray hole, the second pipe, and the fourth spray hole. Alternatively, the disinfectant spray in this state can be left undischarged; when the disinfected pipette is picked up, the disinfectant spray can naturally dissipate into the air). The manual operation process can be automated using existing mature automatic control technology.

3. The disinfection liner according to claim 1, characterized in that, The support rod has multiple limiting notches along its length that match the pipette, and the projection of the limiting notches along the height of the inner liner body is an arc shape.

4. A pipette sterilization instrument, characterized in that, The device includes a box body, a lid, an ultraviolet disinfection lamp, and a disinfection inner liner as described in claim 3. The box body has an installation cavity with a top opening. A matching lid is hinged to the top opening of the box body. Two opposite side walls of the box body each have a third spray hole and a fourth spray hole communicating with the installation cavity. Two other opposite side walls of the box body each have a power cord hole and a second air supply hole communicating with the installation cavity. The disinfection inner liner is disposed within the installation cavity. There is a height difference between the bottom of the inner liner and the bottom of the mounting cavity. The inner bottom surface of the lid has a sealing protrusion for opening / sealing the top inlet of the disinfection inner liner. The ultraviolet disinfection lamp is installed on the mounting base inside the disinfection inner liner. The first spray hole on the disinfection inner liner is connected to the third spray hole through a first pipe. The second spray hole on the disinfection inner liner is connected to the fourth spray hole through a second pipe. The mounting base is provided with a power cord that is connected to an external power source and passes through the power cord hole. The first air outlet is connected to the second air outlet through a third pipe.

5. The pipette sterilization instrument according to claim 4, characterized in that, The insertion port at the top of the sterilization inner liner has a first support edge that bends outward, and the first support edge of the sterilization inner liner is fixedly attached to the second support edge in the upper middle part of the installation cavity.

6. The pipette sterilization instrument according to claim 4, characterized in that, The distance between each of the supporting parts and each of the corresponding suspension positions on the supporting rod is equal.

7. A method of using the pipette sterilization instrument according to any one of claims 4-6, characterized in that, Includes the following steps: Open the lid, suspend the pipette in the suspension position of the support rod, close the lid, and seal the sealing boss of the lid to seal the inlet at the top of the inner liner body. Turn on the external power supply and connect it to the mounting base via the power cord to turn on the ultraviolet disinfection lamp mounted on the mounting base and disinfect the pipette with ultraviolet light. The externally supplied disinfectant spray flows sequentially through the third spray hole, the first pipe, the first spray hole, the second spray hole, the second pipe, and the fourth spray hole to perform a flowing disinfectant spray disinfection on the pipette. When the recorded ultraviolet disinfection and disinfectant spray disinfection time of the pipette reaches the predetermined first disinfection time, the externally supplied gas is injected sequentially into the second gas inlet, the third pipe, the first gas inlet and the air bag gas inlet until the air bag expands and pushes the push plate upward. The pipette is supported by the upward-moving push plate, which moves the pipette upward and detaches it from the hanging position of the support rod. At the same time, the inflated airbag seals the first spray hole and the second spray hole, and stops the external supply of disinfectant spray. This allows the pipette inside the inner cavity to continue to be disinfected by the disinfectant spray sealed in the inner cavity. When the recorded ultraviolet disinfection and disinfectant spray disinfection time of the pipette reaches the predetermined second disinfection time, the external power is turned off, ultraviolet disinfection is stopped, the gas injected into the air bag is extracted, the air bag is contracted and the push plate is moved down, the pipette is moved down and resuspended in the suspension position of the support rod, and the first spray hole and the second spray hole are reconnected. Open the box lid and remove the sterilized pipette from the suspension position on the support rod.
