Description

Technical Field

[0001] The invention relates to the technical field of laboratory operation and biochemical detection, and in particular to a small auxiliary switch cover machine capable of automatic disinfection. Background Art

[0002] In the detection of highly dangerous biological samples such as viruses (such as the new coronavirus), laboratory testers must draw samples from the collected virus sample tubes and transfer them to the next test container. Although this process is very short, when the test tube is opened and closed, the virus sample is very likely to spread through aerosols, posing a great risk of infection to testers.

[0003] For the process of opening and closing the lid for sampling, most of the operations are still manual. Regardless of whether it is a blood collection tube or a test tube, the experimenter opens the lid with both hands and inverts the tube lid on the table. Then, he takes the test tube in one hand and the pipette in the other hand to absorb the virus sample in the test tube and transfer it to the experimental container. This method has many operating steps, which requires a series of tasks such as opening the lid, putting the lid, taking the pipette, sucking the sample, putting the pipette, and closing the lid. All of these must be done with both hands. Once the operation is improper, the test tube is dropped or broken, the virus and its aerosol will spread rapidly, and the consequences will be disastrous. It greatly increases the infection risk of the operator and is prone to cross-contamination. On the other hand, due to the factors of manual operation, there is no effective way to identify and control aerosols, and it is easy to ignore invisible cross-contamination.

[0004] A small number of testing operations have begun to use large-scale opening and closing cover equipment instead of manual operation. Such equipment is often equipped with mobile mechanisms such as manipulators or mobile arms, as well as long test tube row mechanisms that can hold large quantities of test tubes. Although such equipment has a high degree of automation, it also brings the defects of being large and bulky to such equipment, resulting in the entire machine being unable to be placed in a clean bench (a purification device that provides a sterile and dust-free working environment) or a mobile testing vehicle for operation. For samples that require a high level of cleanliness, such equipment cannot meet the requirements. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic auxiliary lid opening and closing machine, which is small in size and portable and can be placed in a variety of experimental environments such as a clean workbench to perform automatic lid opening and closing operations, thereby avoiding cross infection and reducing the risk of infection to inspectors by high-risk viruses (such as the new coronavirus) or infectious pathogenic samples.

[0006] To achieve the above object, the solution of the present invention is: an automatic auxiliary opening and closing machine, comprising:

[0007] A seat having an open cavity and an inner storage space;

[0008] a clamping mechanism, the clamping mechanism being arranged in the open chamber for placing the test tube;

[0009] A switch cover mechanism is escalably disposed on the top of the open chamber and corresponds to the upper side of the clamping mechanism;

[0010] A rotating mechanism, connected to the clamping mechanism, capable of driving the clamping mechanism to flip;

[0011] an aspirator, the aspirator having an air suction port, the air suction port being aligned with the clamping mechanism;

[0012] A filter is connected to the aspirator through a pipeline, the filter has an exhaust port, and the filter and the aspirator are arranged in the inner storage space.

[0013] Furthermore, it also includes a UV lamp, which is installed on the base and located at the front edge of the open chamber.

[0014] Furthermore, it also includes a spotlight, which is installed on the base and located in the open cavity, and emits light source toward the clamping mechanism.

[0015] Furthermore, it also includes a lithium battery, which is installed on the base body and connected to the clamping mechanism, the switch cover mechanism, the aspirator and the filter.

[0016] Furthermore, the switch cover mechanism may adopt a spiral structure.

[0017] Furthermore, the switch cover mechanism includes a cover opener, a rotating motor, a screw, a screw motor, a connecting plate, a slider and a guide rail, the screw and the guide rail are respectively vertically fixed on the base body, the screw motor is engaged with the screw, the slider is engaged with the guide rail, the screw motor is fixed together with the slider through a connecting plate, the rotating motor is installed on the connecting plate, and the end of the rotating motor is connected to the cover opener.

[0018] Furthermore, the switch cover mechanism may adopt a push-pull structure.

[0019] Furthermore, the aspirator may be an aspirating fan.

[0020] Furthermore, the rotating mechanism may adopt a hand-cranked rotating handle.

[0021] Furthermore, the clamping mechanism can clamp test tubes of sizes including 13mmX15mm, 13mmX75mm, and 13mmX100mm.

[0022] After adopting the above scheme, the gain effect of the present invention is:

[0023] The present invention is designed for the switch cover of a single test tube. The clamping mechanism clamps the test tube, and the tube cover is opened by the lifting switch cover mechanism, and then the test tube after opening is tilted by the rotating mechanism, so that the detection personnel can use a pipette to absorb liquid, and the detection personnel do not need to cross their hands to operate and touch the test tube to avoid cross infection. After the liquid is absorbed, the cover is automatically closed to minimize the time of opening the test tube. The present invention also designs an aspirator and a filter. The aspirator is aligned with the clamping mechanism. Whether the test tube is placed in the clamping mechanism or when the cover is opened, the aspirator can absorb the aerosol at the mouth of the test tube, and finally filtered and discharged by the filter. The aerosol path is effectively controlled, thereby minimizing the spread of viral aerosols. The components of the present invention are small in size and simple in structure, so that the present invention is convenient to carry and suitable for use in experimental environments such as clean benches, fume hoods, biosafety cabinets, and mobile detection vehicles, reducing the risk of infection of high-risk virus (such as new coronavirus) samples to inspectors, and greatly promoting the safe development of the biochemical industry.

[0033] like Figure 2 As shown, the seat body 1 has an open chamber 10 and a storage space 11, and the clamping mechanism 2 is arranged in the open chamber 10. The clamping mechanism 2 has a clamping claw that can be used to clamp a test tube 12. The clamping mechanism 3 in this case can clamp test tubes 12 of different diameters commonly used in the market, such as 13mmX15mm, 13mmX75mm, 13mmX100mm, etc. The types of the tube cover 121 in the present invention include screw caps and push-pull caps (such as rubber plugs).

[0034] The switch cover mechanism 3 is movably arranged on the top of the open chamber and corresponds to the upper part of the clamping mechanism. The switch cover mechanism 3 can adopt a spiral structure or a push-pull structure. If the spiral structure is adopted, the corresponding test tube 12 and the tube cover 121 are sealed in a screw-rotating manner. If the push-pull structure is adopted, the corresponding test tube 12 and the tube cover 121 are sealed in a press-pull manner. This embodiment takes the spiral structure as an example. Figure 4 As shown, the lifting mechanism of the switch cover mechanism 3 that can be lifted up and down is specifically, the switch cover mechanism 3 includes a cover opener 16, a rotating motor 17, a screw 18, a screw motor 19, a connecting plate 20, a slider 21 and a guide rail 22, the screw 18 and the guide rail 22 are respectively vertically fixed on the base body 1, the screw motor 19 is matched on the screw 18, the slider 21 is matched with the guide rail 22, the screw motor 19 is fixed together with the slider 21 through the connecting plate 20, the rotating motor 17 is installed on the connecting plate 20, and the end of the rotating motor 17 is connected to the cover opener 16.

[0035] The rotating mechanism is connected to the clamping mechanism 2 and can drive the clamping mechanism 2 to flip. The rotating mechanism can be designed to automatically control the rotation angle of the clamping mechanism or manually control the rotation angle of the clamping mechanism. This embodiment adopts a hand-cranked rotating handle 4, and the clamping mechanism 2 is rotated by moving the rotating handle 4 left and right.

[0036] The aspirator has an air suction port 13, which is aligned with the clamping mechanism 2, so that the aspirator can absorb the aerosol at the test tube mouth whether the test tube is placed in the clamping mechanism 2 or the cover is opened, ensuring as much as possible that the aerosol can be absorbed during the entire use process; the aspirator can use a simple and compact suction fan 5.

[0037] The filter 6 is connected to the air intake fan 5 via a pipeline 14 . The filter 6 has an air outlet 15 . The air outlet 15 is provided with the air exhaust fan. The filter 6 and the air intake fan 5 are arranged in the inner storage space 11 .

[0038] The lithium battery 9 is installed on the base 1, and the lithium battery 9 is connected to the clamping mechanism 2, the switch cover mechanism 3, the suction fan 5 and the filter 6 and provides electric energy for them.

[0039] The base 1 is provided with a UV lamp 7 and a spotlight 8. The UV lamp 7 is located at the front edge of the open chamber 10. Before and after use of the present invention, the UV lamp sterilizes and disinfects the components in the open chamber 10. The UV lamp can be automatically timed. The spotlight 8 is located in the open chamber 10. The spotlight 8 emits light toward the clamping mechanism 2, so that the liquid level of the test tube on the clamping mechanism is displayed, which is convenient for the inspection personnel to observe.

[0040] The invention is convenient to carry and suitable for being placed in a clean bench because of its small size. At the beginning of the experiment, the test tube 12 is placed and clamped on the clamping claws of the clamping mechanism 2 to ensure that the test tube 12 is in a vertical state. The spotlight 8 is automatically turned on, and the test personnel can see the liquid surface. Then, during operation, the lead screw motor 19 is started, so that the lead screw motor 19 slides up and down along the lead screw 18 while driving the connecting plate 20, the slider 21, the rotating motor 17 and the cover opener 16 to move up and down together. The slider 21 and the guide rail 22 play a guiding role. The cover opener 16 descends to the position of the tube mouth, the rotating motor 17 is started, the tube cover 121 is unscrewed, and the air suction wind The fan 5 is opened, the air inlet 13 is facing the tube mouth, and the whole process is inhaled to absorb the sample aerosol pollutants. The inhaled gas passes through the air inlet pipeline 14 and the filter material (including filter mesh, filter paper, filter membrane, etc.) inside the filter 6, which will adhere to the harmful parts of the gas and finally discharge the remaining gas; the cover opener grabs the tube cover and returns to the initial position to complete the cover opening action; after that, the rotating handle 4 is held and slid to the left and right to flip the clamping mechanism 2, causing the test tube 12 to tilt, and after reaching a certain angle, the test personnel can use a pipette to absorb the liquid, and then use the rotating handle to turn the test tube back to the vertical direction, and the cover opener will go down to the tube mouth position, and automatically cover the test tube 12 with the tube cover 121. The present invention is specially designed for the opening and closing cover of a single test tube. The test personnel do not need to cross their hands to operate and touch the test tube to avoid cross infection. After the liquid is absorbed, the cover is automatically closed, which minimizes the time of opening the test tube, thereby minimizing the spread of viral aerosols and reducing the risk of infection of high-risk virus (such as new coronavirus) samples to test personnel, greatly promoting the safe development of the biochemical industry.

[0041] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.
