Description

Technical Field

[0001] This utility model relates to the field of in vitro culture equipment, specifically to an in vitro culture box for fertilized eggs. Background Technology

[0002] In vitro culture of fertilized eggs is a key step in assisted reproductive technology. It simulates the in vivo environment to allow fertilized eggs to develop into embryos, which are then transferred back to the uterus to achieve pregnancy.

[0003] In vitro fertilization (IVF) incubators are core equipment in assisted reproductive technology. By precisely controlling parameters such as temperature, gas concentration, and humidity, they simulate the human uterine environment, providing stable conditions for the in vitro development of fertilized eggs. IVF incubators often employ dry or drawer-type designs. However, existing drawer-type incubators lack a buffer structure when closed. The impact force generated when the drawer collides with the incubator body can cause the culture dishes placed inside to shake, potentially leading to spillage of the culture medium or displacement of the fertilized eggs, thus affecting their normal culture. Utility Model Content

[0004] To address the technical problem that the impact force generated when the drawer collides with the incubator causes the culture dish placed in the drawer to shake, which may lead to the culture medium in the culture dish splashing out or the fertilized egg shifting, affecting the normal culture of the fertilized egg, this utility model provides an in vitro culture box for fertilized eggs.

[0005] The technical solution adopted by this utility model is as follows: It includes an incubator, on which several sets of drawers are slidably arranged. Each set of drawers has a fixedly connected placement ring. A buffer pad is fixedly installed at the bottom of each placement ring. A limit block is fixedly connected to each drawer. Connecting plates are fixedly connected to both side walls of the incubator. A slider is fixedly installed on one side of each connecting plate. A slide rail is slidably arranged outside the slider. The slide rail is fixedly connected to the side of the drawer. A damper is fixedly installed at one end of the connecting plate. A baffle is fixedly connected to the movable end of the damper. A spring is fixedly installed on one side of the baffle. The spring is sleeved outside the movable rod of the damper.

[0006] Furthermore, several sets of rollers are rotatably mounted in the slide rail, and these sets of rollers are evenly distributed at the upper and lower ends of the slider.

[0007] By adopting the above technical solution, the friction between the slide rail and the slider is reduced.

[0008] Furthermore, a first buffer block is fixedly connected to one end of the slide rail near the baffle, and a second buffer block is fixedly installed on the side of the baffle away from the damper. The second buffer block and the first buffer block are used in conjunction with each other.

[0009] By adopting the above technical solution, rigid contact between the slide rail and the baffle is avoided.

[0010] Furthermore, a rotating shaft is fixedly installed on one side of the incubator, the rotating shaft is located above the drawer, and a limiting plate is rotatably installed on the outside of the rotating shaft.

[0011] By adopting the above technical solution, the stability of the drawer after installation in the incubator is improved.

[0012] Furthermore, four sets of support legs are evenly fixedly installed around the bottom of the incubator, and the bottom of the support legs is fixedly connected with shock-absorbing pads.

[0013] By adopting the above technical solutions, the impact of external vibrations on the incubator can be reduced.

[0014] Furthermore, an environmental sensor is fixedly installed on the inner wall of the incubator, a control panel is fixedly installed on the outside of the incubator, an information processing box is located below the control panel, and a controller is also fixedly installed on the outside of the incubator.

[0015] By adopting the above technical solutions, the internal environment of the incubator is kept stable.

[0016] The beneficial effects of this utility model are: by using a connecting plate, sliding plate, drawer, slide rail, damper and spring in conjunction with the incubator, the speed at which the drawer moves into the incubator is slowed down, and the impact of the contact between the drawer and the incubator body when the drawer is closed is reduced, thereby reducing the vibration of the culture dish placed on the drawer, avoiding splashing of the culture medium in the culture dish or displacement of the fertilized egg, ensuring the culture effect of the fertilized egg, and improving the practicality of the incubator.

[0017] By using slide rails and rollers, the friction between the slide rails and the sliders is reduced, thereby reducing vibration during the push-pull movement of the drawer. The slide rails, together with the first buffer block and the baffle, together with the second buffer block, avoid direct rigid contact between the slide rails and the baffles, thereby reducing the impact of the peak impact force generated when the slide rails and the baffles are in direct contact on the drawer and the culture dish on it, and improving the protection effect on the fertilized eggs in the culture dish.

Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 The present invention will be further described below.

[0029] To address the problems existing in the background art, this application proposes the following technical solution: An incubator 1 is included, with several sets of drawers 2 slidably arranged on the incubator 1. Each set of drawers 2 is fixedly connected to a placement ring 3, and a buffer pad 4 is fixedly installed at the bottom of the placement ring 3. A limit block 22 is fixedly connected to each drawer 2. Connecting plates 11 are fixedly connected to both side walls of the incubator 1. A slider 12 is fixedly installed on one side of the connecting plate 11, and a slide rail 13 is slidably arranged outside the slider 12. The slide rail 13 is fixedly connected to the side of the drawer 2. A damper 15 is fixedly installed at one end of the connecting plate 11, and a baffle 18 is fixedly connected to the movable end of the damper 15. A spring 17 is fixedly installed on one side of the baffle 18, and the spring 17 is sleeved outside the movable rod of the damper 15.

[0030] The incubator 1 in this invention adopts a drawer-type design, allowing single-layer extraction, minimizing air exchange, and shortening the recovery time of gas concentration inside the incubator 1. The drawer 2 is pulled out of the incubator 1, and a culture dish containing fertilized eggs is placed in the placement ring 3. A buffer pad 4 cushions the placed culture dish, preventing direct rigid contact between the culture dish and the drawer 2 and reducing shaking. The drawer 2 is then pushed back into the incubator 1. Before the drawer 2 contacts the incubator 1 body, the drawer 2 moves the slide rail 13, which contacts and presses against the baffle 18, pushing the baffle 18 to move. The baffle 18 compresses and deforms the spring 17, storing energy. During this process, the spring 17 absorbs and disperses the impact force through its elastic deformation. When the spring 17 tries to return to its original state, the damper 15 begins to function. The damper 15 prevents the spring 17 from rebounding and consumes the energy previously stored in the spring 17. The damper 15, in conjunction with the spring 17, slows down the speed at which the drawer 2 moves into the incubator 1, while reducing the impact of the contact between the drawer 2 and the incubator 1 on the drawer 2. This reduces the vibration of the culture dish placed on the drawer 2, prevents the culture medium in the culture dish from splashing out or the fertilized egg from shifting, ensures the culture effect of the fertilized egg, and improves the practicality of the incubator 1.

[0031] Furthermore, several sets of rollers 14 are rotatably mounted in the slide rail 13, and these sets of rollers 14 are evenly distributed at the upper and lower ends of the slider 12.

[0032] By setting up several sets of rollers 14, the sliding friction between the slide rail 13 and the slider 12 is transformed into rolling friction between the rollers 14 and the slider 12, which reduces the friction between the slide rail 13 and the slider 12, thereby reducing the vibration during the push-pull movement of the drawer 2.

[0033] To further explain, a first buffer block 16 is fixedly connected to one end of the slide rail 13 near the baffle 18, and a second buffer block 19 is fixedly installed on the side of the baffle 18 away from the damper 15. The second buffer block 19 and the first buffer block 16 are used in cooperation with each other.

[0034] When the damper 15 works with the spring 17 to reduce the shock in the drawer 2, the cooperation between the first buffer block 16 and the second buffer block 19 avoids direct rigid contact between the slide rail 13 and the baffle 18, thereby reducing the impact of the peak impact force generated when the slide rail 13 and the baffle 18 are in direct contact on the drawer 2 and the culture dish on it, and improving the protection effect on the fertilized eggs in the culture dish.

[0035] To further explain, a rotating shaft 20 is fixedly installed on one side of the incubator 1. The rotating shaft 20 is located above the drawer 2, and a limiting plate 21 is rotatably installed on the outside of the rotating shaft 20.

[0036] After pushing drawer 2 back onto incubator 1, rotate the limiting plate 21 outside the rotating shaft 20 to rotate the limiting plate 21 to a vertical position (as shown in the attached diagram). Figure 1 As shown in the attached diagram, the limiting plate 21 rotates to the surface of drawer 2, restricting the movement of drawer 2 and ensuring the petri dish is stably preserved inside the incubator 1. An elastic sealing strip is installed between drawer 2 and the incubator 1 body. The elasticity of the sealing strip seals the gap between drawer 2 and the incubator 1 body, preventing the exchange of gas between the inside and outside of the incubator 1 and improving the stability of the internal environment of the incubator 1. When it is necessary to pull drawer 2 out of the incubator 1, the limiting plate 21 is rotated to a horizontal position (as shown in the attached diagram). Figure 7 As shown), the limit plate 21 is released from restricting the movement of drawer 2. At this time, the compressed spring 17 pushes drawer 2 out of incubator 1 a part, making it easier for the operator to pull drawer 2 out of incubator 1. At the same time, due to the setting of damper 15, drawer 2 moves slowly when spring 17 pushes drawer 2, so as not to affect the culture dish on drawer 2.

[0037] Furthermore, four sets of support legs 5 are evenly fixedly installed around the bottom of the incubator 1, and anti-vibration pads 6 are fixedly connected to the bottom of the support legs 5.

[0038] The shock-absorbing pad 6 is made of silicone or rubber. The support legs 5 and the shock-absorbing pad 6 isolate the incubator 1 from the experimental table. The shock-absorbing pad 6 can absorb the vibration generated by personnel walking or other equipment operation, thereby reducing the impact of external vibration on the incubator 1.

[0039] Furthermore, an environmental sensor 7 is fixedly installed on the inner wall of the incubator 1, a control panel 8 is fixedly installed on the outside of the incubator 1, an information processing box 9 is located below the control panel 8, and a controller 10 is also fixedly installed on the outside of the incubator 1.

[0040] The environmental sensor 7 is used to monitor the environment inside the incubator 1, providing suitable temperature, humidity, and pH values ​​for the fertilized eggs. The incubator 1 is equipped with an environmental control module, such as a dual temperature control module, which works with the environmental sensor 7 to keep the internal temperature of the incubator 1 constant. The control panel 8 is used to directly adjust or view the various environmental data inside the incubator 1 from the outside. The information processing device in the information processing box 9 processes the data collected by the environmental sensor 7 and transmits it to the controller 10. The controller 10 coordinates the cooperation between the various environmental control modules. The controller 10 uses a programmable PLC controller to maintain the environment inside the incubator 1 in a suitable environment for the development of the fertilized eggs.

[0041] The environmental sensor 7, control panel 8, information processing box 9, controller 10, and damper 15 of the fertilized egg in vitro culture chamber of this utility model are all purchased from the market and are existing technologies. Those skilled in the industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art. The electrical components are connected by conventional electrical connections, and the controller 10 is simply programmed according to the instruction manual. This utility model does not modify the circuit connections or program writing. At the same time, the environmental control module in the culture chamber 1 adopts the same technology as the existing fertilized egg in vitro culture technology, which will not be described in detail here.

[0042] The specific operation is as follows: Pull drawer 2 out of incubator 1, place the culture dish containing fertilized eggs into the placement ring 3, and cushion the culture dish with buffer pad 4. Then push drawer 2 back into incubator 1. The slide rail 13 slides on the slider 12. Before drawer 2 contacts the body of incubator 1, the first buffer block 16 contacts and presses against the second buffer block 19. The second buffer block 19 drives the baffle 18 and spring 17 to move. The damper 15, in conjunction with the spring 17, slows down the speed at which drawer 2 moves into incubator 1, and at the same time reduces the impact of the contact between drawer 2 and the body of incubator 1 on drawer 2, thereby reducing the vibration of the culture dish placed on drawer 2 and preventing the culture medium in the culture dish from splashing out or the fertilized eggs from shifting. After pushing drawer 2 back into incubator 1, rotate the limiting plate 21 outside the rotating shaft 20 to rotate the limiting plate 21 to a vertical position, so that the culture dish is stably preserved inside incubator 1.

[0043] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
