DETAILED DESCRIPTION
[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0038] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: An in vitro cytotoxicity test device for an anesthesia breathing pipeline, including a housing 1. The housing 1 is a device for placing a cell culture dish 5 during the in vitro cytotoxicity test of the anesthesia breathing pipeline. The pipeline sample can be placed in the culture dish 5, and the culture dish 5 is placed in the housing 1 for testing and observation. This is prior art. A clamping groove 6 is provided on the outer wall of the front end of the housing 1, and the cover plate 301 can be fixed when it is closed through the clamping groove 6. A jacking mechanism 2 is provided on the inner wall of the housing 1. Through the jacking mechanism 2, the culture dish 5 can be taken out conveniently and quickly, so that the culture dish 5 can be replaced.
[0039] Referring to Figure 3 - Figure 5 , the jacking mechanism 2 includes a partition plate 201. The outer wall of the partition plate 201 is slidably connected to the inner wall of the housing 1. The culture dish 5 can be placed on the partition plate 201 for testing. When the partition plate 201 moves upward, it can drive the culture dish 5 to move upward, facilitating the operator to take out the culture dish 5. The top outer wall of the partition plate 201 is in contact with the culture dish 5, and cell culture medium is placed in the culture dish 5. This is prior art. The pipeline sample can be placed in the culture dish 5, and then the culture dish 5 is placed on the partition plate 201 for testing and observation. A connecting rod 202 is fixedly connected to the bottom outer wall of the partition plate 201. The bottom outer wall of the connecting rod 202 is hinged to a rotating rod 203. The outer wall of the rotating rod 203 is slidably connected to a sleeve rod 204. The sleeve rod 204 penetrates through the front outer wall of the housing 1. When the front end of the sleeve rod 204 is pressed, the rotating rod 203 can slide in the inner wall of the sleeve rod 204 and turn upward, driving the partition plate 201 to move upward through the connecting rod 202.
[0040] Referring to Figure 3 - Figure 5 , a fixing plate 205 is fixedly connected to the front outer wall of the housing 1. The sleeve rod 204 is rotatably connected to the outer wall of the fixing plate 205. When the front end of the sleeve rod 204 is pressed, the sleeve rod 204 can turn upward along its connection with the fixing plate 205. Without external force, the partition plate 201 moves downward, keeping the front end of the sleeve rod 204 upward. An opening and closing assembly 3 is provided on the top outer wall of the housing 1. Through the opening and closing assembly 3, multiple culture dishes 5 can be simultaneously covered and closed or opened, or a certain group of culture dishes 5 can be separately opened and taken out for replacement.
[0041] Referring to Figure 4 - Figure 5, the opening and closing assembly 3 includes a cover plate 301, which is hinged to the outer wall of the top end of the housing 1. The cover plate 301 can be flipped to open or close multiple groups of culture dishes 5 simultaneously. A fixed block 302 is fixedly connected to the outer wall of the top end of the cover plate 301. The fixed block 302 is arranged in the middle part of the cover plate 301. A stopper 305 is elastically connected to the inner wall of the fixed block 302 through a spring A 304. Both the stopper 305 and the spring A 304 are provided in two groups and are symmetrically distributed on the inner walls of both sides of the fixed block 302. One end of the spring A 304 is fixedly connected to the outer wall of the stopper 305, and the other end of the spring A 304 is fixedly connected to the inner wall of the fixed block 302. Without the influence of external forces, the spring A 304 drives the stopper 305 to pop outwards due to its own elastic force and limits the rotating plate 303, so that the rotating plate 303 is closed.
[0042] Refer to Figure 4 - Figure 5 , the outer wall of the stopper 305 is slidably connected to the inner wall of the fixed block 302. The stopper 305 contacts the outer wall of the top end of the rotating plate 303. When the stopper 305 is pressed to move inwards along the inner wall of the fixed block 302 until it disengages from the rotating plate 303, the rotating plate 303 can be opened, and a group of culture dishes 5 can be taken out and replaced separately. A fixed rod 306 is fixedly connected to the inner wall of the cover plate 301. The outer wall of the fixed rod 306 is elastically connected to a rotating plate 303 through a scroll spring 307. The rotating plate 303 is transparent to facilitate observing the test progress in the culture dish 5. When the cover plate 301 is closed, the rotating plate 303 contacts the outer wall of the top end of the culture dish 5, and the culture dish 5 can be closed. When the rotating plate 303 flips downwards, the fixed rod 306 remains fixed, and the scroll spring 307 is stressed and contracts.
[0043] Refer to Figure 4 - Figure 5 , one end of the scroll spring 307 is fixedly connected to the inner wall of the rotating plate 303, and the other end of the scroll spring 307 is fixedly connected to the outer wall of the fixed rod 306. When the stopper 305 disengages from the rotating plate 303, the scroll spring 307 can drive the rotating plate 303 to automatically flip upwards due to its own elastic force, thereby opening the culture dish 5. The rotating plate 303 is rotatably connected to the inner wall of the cover plate 301. When the cover plate 301 is closed and a certain group of culture dishes 5 needs to be taken out and replaced separately, the corresponding rotating plate 303 can be opened for replacement without opening the entire cover plate 301. A limiting mechanism 4 is arranged on the front outer wall of the cover plate 301. Through the limiting mechanism 4, the cover plate 301 can be opened or closed conveniently and quickly.
[0044] Refer to Figure 6, the limiting mechanism 4 includes a bump 401, the bump 401 is fixedly connected to the front outer wall of the cover plate 301, the inner wall of the bump 401 is elastically connected with a clamping block 403 through a spring B402, the clamping block 403 penetrates through the outer wall of the bump 401 and can move horizontally in the inner wall of the bump 401. One end of the spring B402 is fixedly connected to the outer wall of the clamping block 403, and the other end of the spring B402 is fixedly connected to the inner wall of the bump 401. When the cover plate 301 is closed, the spring B402 can drive the clamping block 403 to pop outwards due to its own elastic force and be clamped with the clamping groove 6, so as to keep the cover plate 301 in a closed state. The outer wall of the clamping block 403 is slidably connected to the inner wall of the bump 401, and the clamping block 403 is clamped with the clamping groove 6. When it is necessary to open the cover plate 301, the clamping block 403 can be pulled outwards to disengage from the clamping groove 6, so as to release the limit of the cover plate 301 and open the cover plate 301.
[0045] Working principle: When it is necessary to perform an in vitro cytotoxicity test on an anesthesia breathing circuit, multiple culture dishes 5 filled with cell culture medium can be placed on the partition plate 201 first, then the pipeline sample can be placed in the culture dish 5, and then the cover plate 301 can be flipped downwards to pull the clamping block 403. When the cover plate 301 is flipped to a position where the clamping block 403 corresponds to the clamping groove 6, release the clamping block 403. The spring B402 can drive the clamping block 403 to pop outwards and be clamped with the clamping groove 6 due to its own elastic force, thereby fixing the cover plate 301 and closing multiple groups of culture dishes 5 at the same time, saving time. Since the rotating plate 303 is transparent, the test reaction in the culture dish 5 can be observed through the rotating plate 303.
[0046] Since the samples in multiple groups of culture dishes 5 are different, the required test operation times are also different. When it is necessary to take out a certain group of culture dishes 5 after the test time ends, the corresponding stop block 305 above the group of culture dishes 5 can be pressed inwards to disengage from the rotating plate 303. At this time, the rotating plate 303 automatically flips upwards due to the elastic force of the volute spring 307, opening the group of culture dishes 5. Then, the sleeve rod 204 corresponding to the group of culture dishes 5 can be pressed, so that the sleeve rod 204 drives the rotating rod 203 to flip upwards. The rotating rod 203 moves inwards along the inner wall of the sleeve rod 204 and can drive the connecting rod 202 and the partition plate 201 to move upwards, lifting the group of culture dishes 5 upwards, so that the group of culture dishes 5 can be taken out and replaced.
[0047] After a new set of culture dishes 5 are placed on the partition plate 201, the rotating plate 303 can be flipped downward. The scroll spring 307 is stressed and contracts, and the rotating plate 303 squeezes the arc surface of the stopper 305, causing the stopper 305 to move inward along the inner wall of the fixed block 302. When the rotating plate 303 is completely closed, the stopper 305 pops out outward due to the elastic force of the spring A 304, and then the rotating plate 303 can be limited to keep the rotating plate 303 in a closed state. When all the culture dishes 5 are tested at the same time, the latch 403 can be pulled outward, and then the cover plate 301 can be flipped upward, and at the same time, multiple groups of culture dishes 5 are opened, and the culture dishes 5 are taken out by pressing the sleeve rod 204. During the test process, it is not necessary to close or open the culture dishes 5 one by one, which is more time-saving and labor-saving and improves work efficiency.
[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
