Description

Technical Field

[0001] The present invention relates to the technical field of cell culture equipment, and in particular, to a desktop portable cell culture aseptic operation table. Background Art

[0002] Cell culture refers to a method of simulating the in vivo environment (aseptic, appropriate temperature, pH value, and certain nutrient conditions, etc.) in vitro to enable cells to survive, grow, reproduce, and maintain their main structures and functions. It is a common means in biology. In the prior art, large cell culture instruments are generally used for cell culture. Although the inside of the culture instrument is an aseptic environment, there will still be a situation of bacteria-carrying operation during the actual operation process, thus destroying the aseptic environment in the culture dish and interfering with the culture results.

[0003] During the cell culture process, various treatment operations need to be performed on the culture dish, such as adding culture medium, etc. At this time, the culture dish needs to be taken out of the culture instrument and placed on an ordinary workbench for operation and treatment. Although this process is short, it will still destroy the aseptic environment in the culture dish. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems in the related art to some extent: to provide a desktop portable cell culture aseptic operation table, which can be portably placed on various work surfaces, used to create a temporary aseptic environment, so that the culture vessels with cells can be placed in this aseptic environment, and at the same time, it is convenient for operators to perform treatment operations on the culture vessels.

[0005] To this end, an object of the present invention is to propose a desktop portable cell culture aseptic operation table, which includes a bracket and a carrier provided on the bracket. The carrier includes a housing connected to the bracket. The housing has a receiving groove with an upward opening direction. The receiving groove includes a functional area for placing culture vessels and a plurality of air holes arranged around the functional area. The functional area is located at the middle position of the receiving groove in the horizontal direction. Each air hole is arranged to face outside the receiving groove for forming an air wall around the functional area. The housing is provided with a gas supply device for supplying high-pressure clean air to each air hole. The airflow generated by the air holes can form an air wall around the functional area, thereby isolating the culture vessels placed in the functional area of the receiving groove from the air in the external environment and creating a relatively aseptic environment.

[0006] According to an example of the present invention, a turntable is provided on the bracket. The housing is located below the turntable and is connected to the turntable. The turntable is rotationally matched with the bracket for driving the housing to rotate. By means of the turntable, the housing can be arbitrarily rotated by the operator, so that any one of the multiple culture vessels located in the receiving groove can be rotated to the side close to the operator as the housing rotates.

[0007] According to an example of the present invention, a top plate is provided on the turntable above the receiving tank, and a gap is left between the top plate and the notch of the receiving tank for taking and placing the culture vessel. The top plate is suspended above the receiving tank, and cooperates with the air wall blown out of the air hole to cover the entire functional area, isolating the convection of the internal and external air, so that the functional area maintains a sterile environment.

[0008] According to an example of the present invention, the shell and the turntable are connected by a connecting arm, and the connecting arm is configured to allow the relative position between the shell and the turntable to be adjustable, so that the top plate covers the notch of the receiving groove or is away from the notch of the receiving groove and forms a spacing for taking and placing the culture vessel, and the top plate has an air outlet for connecting the top plate and the inner cavity formed by the receiving groove. The relative position between the shell and the top plate can be adjusted by the connecting arm, and when the culture vessel does not need to be processed, the shell is moved to the top plate to cover the notch of the receiving groove to improve the effect of isolating the external air, and when the culture vessel needs to be processed, the position of the shell can be adjusted to make the spacing width between the shell and the top plate adjustable to adapt to the operating habits of different operators.

[0009] According to an example of the present invention, connecting arms are symmetrically arranged on both sides of the shell, and the connecting arms are composed of a plurality of mutually hinged arms, any two adjacent arms are hinged to each other, the upper end of the first arm is hinged to the turntable, and the lower end of the last arm is hinged to the shell, and friction dampers are arranged between any two adjacent arms, between the first arm and the turntable, and between the last arm and the shell, and the friction dampers are arranged to keep the shell in the current position after the external force driving the shell to move is eliminated. The connecting arms with multiple mutually hinged arms make the shell not only adjustable in the vertical position, but also adjustable in the front-rear direction, so that the shell is closer to the operator, making it more convenient for the operator to handle the culture vessel.

[0010] According to an example of the present invention, the top plate has an annular interface matching the notch position of the accommodating groove, and the air outlet is arranged on the side wall of the annular interface.

[0011] According to an example of the present invention, the interior of the shell has an equipment installation cavity, the air supply device includes a fan installed in the equipment installation cavity and a motor for driving the fan, the shell is provided with an air inlet connected to the equipment installation cavity, an air flow channel connecting the air inlet and the air hole is formed in the equipment installation cavity, and the fan is arranged in the air flow channel.

[0012] According to an example of the present invention, an ultraviolet lamp for providing ultraviolet rays and a heating wire for heating air are provided in the device installation cavity, and the ultraviolet lamp and the heating wire are arranged in sequence along the air flow direction in the air flow channel. The air inhaled through the air inlet can be sterilized by the ultraviolet lamp, and the sterilized air can be heated by each heating wire, so as to change the temperature of the environment where the culture dish is located, so that the cell culture can be completed in a suitable temperature in the culture dish.

[0013] According to an example of the present invention, the bracket includes two vertical rods arranged at intervals, the lower ends of the vertical rods are provided with support feet, a cross bar is arranged between the two vertical rods, and both ends of the cross bar are fixed to the upper ends of the two vertical rods respectively. The turntable is installed at the middle position of the cross bar and is rotationally matched with the cross bar.

[0014] According to an example of the present invention, the vertical rod is a telescopic rod that can be telescoped along its own length direction.

[0015] The above technical solutions have the following advantages or beneficial effects: First, the carrier can be arbitrarily placed on the existing workbench along with the bracket, which is convenient for handling and use. Secondly, the air holes arranged around the functional area on the shell can blow air outwards to form an air wall around the functional area, isolating the environment where the functional area is located from the external environment, thereby creating a relatively sterile environment for the culture dishes in the functional area. Secondly, by driving the shell to rotate through the turntable, the culture dishes on the side far from the operator in the plurality of culture dishes in the accommodating groove can be rotated to be close to the operator, making it convenient for the operator to handle and operate each culture dish. Secondly, the shell is connected to the turntable through a connecting arm, so that the shell can realize the adjustment of the upper and lower heights. When it is necessary to process the culture dishes, the operator can drive the shell to move up or down, so that the distance left in the middle is suitable for the operator's operation habits. When it is not necessary to process the culture dishes, the operator can drive the shell to move up until the top plate covers the opening of the accommodating groove, thereby isolating the space in the accommodating groove by the top plate, improving the tightness, and the air holes continuously inflate inwards to create a positive-pressure sterile environment. Secondly, the shell is connected to the turntable through the connecting arm of the multi-section support arm, so that the shell can not only adjust the upper and lower heights, but also adjust the front and rear positions. The operator can drive the shell to move forward to the position where the operator stands, so as to facilitate the operator to process the culture dishes in the accommodating groove. Finally, the air blown out by the air holes is constant-temperature clean air through the built-in ultraviolet lamp and heating wire.

[0016] The additional aspects and advantages of the present invention will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present invention. Description of the Drawings

Specific Embodiments

[0025] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] The desktop portable cell culture sterile operation table according to the embodiments of the present invention will be described in detail below with reference to the drawings.

[0027] The present invention provides a desktop portable aseptic operation table for cell culture. As shown in the figure, it includes a bracket and a carrier disposed on the bracket. The bracket is a movable and transportable bracket structure. The carrier includes a housing 4 connected to the bracket. The housing 4 is a cylindrical structure. The top of the housing 4 has a receiving groove 5 with an upward opening direction. The receiving groove 5 includes a functional area 5.1 for placing culture vessels 18 and a plurality of air holes 6 arranged around the functional area 5.1. The functional area 5.1 is located at the middle position of the receiving groove 5 in the horizontal direction. Each air hole 6 is arranged to face outside the receiving groove 5 for forming an air wall around the functional area 5.1. A gas supply device for supplying high-pressure clean air to each air hole 6 is provided on the housing 4.

[0028] In this embodiment, after the gas supply device is powered on, it can continuously supply clean compressed air. After the compressed air is ejected through the air holes 6, it can form an annular air wall, thereby separating the space where the functional area 5.1 is located from the external environment. And as the air flow in the air holes continues to be ejected, the original air in the functional area 5.1 will also be carried away from the functional area 5.1 by the air flowing inside the air wall. Part of the clean air ejected from the air holes is supplemented into the functional area 5.1, and finally the functional area 5.1 is a sterile and clean environment compared with the external environment.

[0029] In the above embodiment, the operator is generally located on one side of the carrier. When the operator operates the multiple culture vessels 18 in the receiving groove 5, it is more convenient to operate the culture vessels 18 close to the operator, and it is more inconvenient to operate the culture vessels 18 far from the operator. Therefore, based on the improvement of the above embodiment: A turntable 13 is provided on the bracket. The housing 4 is located below the turntable 13 and is connected to the turntable 13. The turntable 13 is rotationally matched with the bracket for driving the housing 4 to rotate.

[0030] Preferably, the turntable 13 includes an outer ring and an inner ring. The inner ring and the outer ring are rotationally matched. The outer ring is fixedly connected to the bracket, and the housing 4 is connected to the inner ring. Thus, the operator can rotate the housing 4 so that the culture vessels 18 at various circumferential positions of the receiving groove 5 can be rotated to the side close to the operator, facilitating operations such as taking and placing of each culture vessel 18.

[0031] Based on one of the preferred examples of the air holes in the above embodiment: The air holes are arranged axially upward along the receiving groove. The air wall formed by the high-speed air flow ejected from all the air holes is annular. However, there is still a position above the receiving groove that cannot be covered by the air wall. Therefore, as Figure 5 and Figure 6As shown in the figure, a top plate 14 is provided at a position on the turntable 13 above the accommodation groove 5, and a spacing for placing and removing the culture vessel 18 is left between the top plate 14 and the notch of the accommodation groove 5. The spacing between the top plate 14 and the notch of the accommodation groove 5 serves as a working passage for the operator to operate on the culture vessel 18 in the accommodation groove 5. In this embodiment, the top of the annular air wall formed by the air holes will align with the top plate 14. Thus, the top plate 14, the air wall, and the accommodation groove 5 can enclose and form a sterile space, isolated from the air in the external environment.

[0032] Based on the second preferred example of the air holes in the above embodiment: As Figure 5 shown in the figure, the air holes at the bottom of the accommodation groove 5 are arranged to face upward in the vertical direction and inclined in the horizontal direction toward the middle position where the center line of the accommodation groove is located. Thus, the air flows ejected from the circumferentially arranged air holes can form a conical air wall outside the functional area, and the conical air wall covers the functional area. Thereby, it can well block the convection of the air in the external environment and the air in the functional area, creating a sterile environment.

[0033] In the above embodiment, the larger the spacing between the top plate 14 and the notch of the accommodation groove 5, the more convenient it is for the operator to operate on each culture vessel 18 placed in the accommodation groove 5. However, too large a spacing will make the isolation effect of the air wall blown out by the air holes worse, affecting the sterile isolation effect. On the contrary, the smaller the spacing between the top plate 14 and the notch of the accommodation groove 5, the more conducive it is to keeping the environment in the accommodation groove 5 sterile. However, too small a spacing brings inconvenience to the operator's operation. For this reason, the improvement in this embodiment is that: the housing 4 and the turntable 13 are connected by a connecting arm 17, and the connecting arm 17 is arranged to allow the relative position between the housing 4 and the turntable 13 to be adjustable, so that the housing 4 has a static state of covering the notch of the accommodation groove 5, and an operating state of being away from the notch position of the accommodation groove 5 and forming a spacing for placing and removing the culture vessel 18. Among them Figures 1-6 the housing 4 is in a static state, among which Figure 7 the housing 4 is in an operating state. In this embodiment, when the operator does not need to handle the culture vessel 18, the housing 4 can be pushed to move the housing 4 to Figure 7 the shown static state. At this time, the top plate 14 serves as a cover plate to completely cover the notch position of the accommodation groove 5, so that when the accommodation groove 5 maintains a positive pressure, the air in the external environment is completely blocked from entering the accommodation groove 5. When the operator needs to handle the culture vessel 18 in the accommodation groove 5, only the housing 4 needs to be pulled so that a sufficient spacing for the operator to operate is left between the housing 4 and the top plate 14. This spacing can be adjusted according to the needs of different operators. At this time, the housing 4 is in an operating state.

[0034] Preferably, an air outlet 16 is provided on the top plate 14 for communicating the top plate 14 with the inner cavity formed by enclosing the receiving groove 5. Specifically, a filter screen is provided on the air outlet 16. Thus, when the housing 4 is in a static state and the air supply device continuously inflates the receiving groove 5, the excess air can flow out from the air outlet 16 to ensure the positive pressure in the receiving groove 5 and maintain a sterile environment.

[0035] Furthermore, as Figure 5 and Figure 6 shown, an annular interface 15 matching the notch position of the receiving groove 5 is provided on the top plate 14. The annular interface 15 is an annular cylindrical structure. The upper end of the annular interface 15 is fixed to the lower end surface of the top plate 14, and the lower end of the annular interface 15 matches the notch position of the receiving groove 5. The air outlet 16 is arranged on the side wall of the annular interface 15. The air outlet 16 is preferably multiple, and the multiple air outlets 16 are evenly arranged along the circumferential direction on the side wall of the annular interface 15.

[0036] In this embodiment, as Figure 5 shown, when the top plate 14 descends and encloses with the notch position of the receiving groove 5, a good sterile and sealed environment can be formed. To further improve the sterilization effect on this sealed environment, an auxiliary ultraviolet lamp 19 is provided in the cavity formed by enclosing the top plate 14, the annular interface 15 and the receiving groove 5. The auxiliary ultraviolet lamp 19 is connected to the top plate 14 or the upper part of the annular interface 15 close to the auxiliary ultraviolet lamp 19 for sterilizing the cavity.

[0037] Furthermore, a sensor 20 for detecting whether the receiving groove 5 of the housing 4 and the annular interface 15 below the top plate 14 are in a closed state and a controller 21 for receiving the signal of the sensor 20 are further provided on the carrier. The controller 21 is communicatively connected to the auxiliary ultraviolet lamp 19. Specifically. The sensor 20 is a position sensor installed on the annular interface 15. When the annular interface 15 and the receiving groove 5 are closed, the position sensor 20 on the annular interface 15 contacts the groove side wall of the receiving groove 5 and gives a detection signal. The controller 21 receives the detection signal sent by the position sensor 20 and controls the auxiliary ultraviolet lamp 19 to turn on; conversely, when the annular interface 15 and the receiving groove 5 are disengaged, the detection signal of the position sensor 20 disappears, and the controller 21 controls the auxiliary ultraviolet lamp 19 to automatically turn off. The controller 21 can be installed on the housing 4 or the top plate 14 or the bracket 100.

[0038] Based on one of the preferred examples of the connecting arm 17 in the above embodiment: As Figures 5-7As shown, connecting arms 17 are symmetrically arranged on both sides of the housing 4. The connecting arm 17 is composed of a plurality of articulated arms 17.1. Any two adjacent arms 17.1 are articulated to each other. The upper end of the first arm 17.1 is articulated to the turntable 13, and the lower end of the last arm 17.1 is articulated to the housing 4. Friction dampers are provided between any two adjacent arms 17.1, between the first arm 17.1 and the turntable 13, and between the last arm 17.1 and the housing 4. The friction damper is configured to enable the housing 4 to remain in its current position after the external force driving the housing 4 to move is eliminated.

[0039] Preferably, the connecting arm 17 includes three arms 17.1. The upper end of the first arm 17.1 is articulated to the convex shaft on the turntable 13, the upper end of the second arm 17.1 is articulated to the lower end of the first arm 17.1, the upper end of the last arm 17.1 is articulated to the lower end of the second arm 17.1, and the lower end of the last arm 17.1 is articulated to the convex shaft on the outer side wall of the housing 4. The articulation in this embodiment is also called pivot connection, and friction dampers are provided at each articulation. Therefore, when the housing 4 is subjected to an external force, it can move by overcoming the frictional resistance of each friction damper. When the external force is removed, the housing 4 can overcome its own gravity and remain in its current position by relying on the frictional resistance provided by each friction damper.

[0040] It should be understood that the friction damper is a commercially available product in the industry. On the premise that the friction damper is used to realize that the pivot joint remains in its current position after rotating to any position in this embodiment, it is simple to install each friction damper according to different types of friction dampers in the prior art. Therefore, the structure and installation relationship of this friction damper are not elaborated in detail in this embodiment.

[0041] Based on the second preferred example of the connecting arm 17 in the above embodiment: The upper end of the connecting arm is fixedly connected to the turntable 13. A slide rail is provided along the length direction of the connecting arm. A slider is provided on the outer side wall of the housing 4. The slider is slidably matched with the slide rail, and a locking mechanism for locking the slider is provided on the slide rail. Thus, when the housing 4 slides to any required position, the operator locks the slider through the locking mechanism, so that the housing 4 remains in its current position.

[0042] It should be understood that the slide rail mechanism composed of such a slide rail and a slider is a conventional product in the industry. For example, a linear motor, an electric push rod, etc. can drive the slider to move on the slide rail and remain at any required position.

[0043] Based on the preference of the gas supply device in the above embodiment, such as Figures 5-6As shown, the interior of the housing 4 has an equipment installation cavity 7. The air supply equipment includes a fan 9 installed in the equipment installation cavity 7 and a motor 8 for driving the fan 9. An air inlet 12 communicating with the equipment installation cavity 7 is provided on the side wall of the housing 4. A number of partition plates are provided in the equipment installation cavity 7, and each partition plate divides the inner cavity of the equipment installation cavity 7 into an air flow channel and a motor cavity for accommodating the motor 8. The motor 8 is fixed in the motor cavity, the fan 9 is arranged in the air flow channel, and the output shaft of the motor 8 penetrates through the motor cavity and is connected to the fan 9 in the air flow channel to drive the fan 9. The two ends of the air flow channel are respectively communicated with the air inlet 12 and the air hole 6, and the fan 9 drives the air in the air flow channel to flow towards the position where the air hole 6 is located.

[0044] Specifically, the equipment installation cavity 7 includes a fan cavity, an intermediate cavity located between the fan cavity and the accommodating groove. A plurality of annular partition plates are sequentially arranged radially outward in the intermediate cavity, dividing the intermediate cavity into a channel with an S-shaped longitudinal section. The middle position of the fan cavity is communicated with the middle position of the intermediate cavity through a central hole. The motor cavity is located at the middle position of the intermediate cavity. The motor 8 is located in the motor cavity, and the output shaft of the motor 8 passes through the central hole in the vertical direction and is connected to the fan 9 in the fan cavity. The proximal end of the S-shaped channel is communicated with the fan cavity through the central hole, and the distal end is communicated with each air hole. An ultraviolet lamp 10 for providing ultraviolet rays and a heating wire 11 for heating air are provided in the equipment installation cavity 7, and the ultraviolet lamp 10 and the heating wire 11 are sequentially arranged along the direction of air flow in the S-shaped channel. The ultraviolet lamp should be arranged at a position far from the air hole to avoid part of the ultraviolet rays generated by the ultraviolet lamp from being emitted through the air hole.

[0045] Further, a power supply for supplying electric energy to the heating wire 11 and the motor 8 is provided on the housing. The power supply can be a storage battery or a power cord for electrically connecting to an external power supply.

[0046] Preferably, a filter screen is provided on the air inlet or in the air flow channel for filtering the air inhaled into the air flow channel, so that the air blown out from the air hole is constant-temperature clean air.

[0047] Based on the preference of the above embodiment, as Figures 5-7 shown, the culture vessels 18 for cell culture include bottle-shaped culture bottles and flat culture dishes.

[0048] Preferably, a shelving rack is provided in the accommodating groove 5. The shelving rack is composed of two mutually hinged flat plates. A friction damper for increasing the frictional resistance is provided between the two flat plates. By swinging the two flat plates, the angle between the two flat plates can be adjusted. One of the flat plates in the shelving rack is placed in the accommodating groove and fits the bottom of the accommodating groove, and the other flat plate is in an inclined state. The culture vessel 18 is placed on the inclined flat plate, so that the culture vessel 18 can be placed in the accommodating groove 5 in an inclined manner.

[0049] Improvements based on the above embodiments: As Figures 1-4 shown, the bracket includes two vertical rods 1 arranged at intervals. The lower end of the vertical rod 1 is provided with a support foot 2. A cross bar 3 is arranged between the two vertical rods 1. Both ends of the cross bar 3 are respectively fixed to the upper ends of the two vertical rods 1. The turntable 13 is installed at the middle position of the cross bar 3 and is rotationally matched with the cross bar 3.

[0050] The vertical rod 1 is a telescopic rod that can be telescoped along its own length direction. The telescopic rod includes but is not limited to an electric push rod.

[0051] In the above embodiments, the vertical rod 1 and the cross bar 3 are made of lightweight metal or plastic materials, so that it is convenient for the entire desktop portable cell culture sterile operation table to be placed on various carriers 300.
