TECHNICAL FIELD
[0001] The utility model relates to the technical field of cell culture equipment, and specifically relates to a portable desktop cell culture device. BACKGROUND
[0002] Cell culture refers to a method of simulating the in-vivo environment (sterile, suitable temperature, pH and certain nutritional conditions, etc.) in vitro to make it survive, grow, reproduce and maintain the main structure and function. It is a common means in biology. In the prior art, cell culture generally uses large cell culture instruments. Although the culture instrument is a sterile environment, there are still cases of bacterial operation in actual operation, which destroys the sterile environment in the culture dish and interferes with the culture results.
[0003] During cell culture, various types of handling operations need to be performed on the culture dish, such as adding culture solution. At this time, the culture dish needs to be taken out of the culture instrument and placed on a common workbench for operation and handling. Although this process is short, it still destroys the sterile environment in the culture dish.
[0004] The prior art pays more attention to the sterile requirements of the culture instrument itself. Since the culture dish is taken out for a short time during the culture process, the operator generally tends to ignore the sterile operation requirements during this process. However, the developers of the culture instrument do not consider the culture dish taking-out operation during the culture process. Therefore, the current situation in the industry is that when the culture dish is taken out of the large culture instrument for operations such as liquid replenishment, the operator directly operates on the existing workbench. Obviously, this process causes bacterial contamination of the cells in the culture dish from the external environment. UTILITY MODEL CONTENT

DETAILED DESCRIPTION
[0026] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples for explaining the present application and should not be construed as limiting the present application.
[0027] The portable desktop cell culture device according to the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0028] The present application provides a portable desktop cell culture device, as shown in the drawings, which comprises a shell 1, the top of the shell 1 has an accommodating groove 2 with the opening direction upward, the middle position of the accommodating groove 2 has a functional area 2.1 for placing a culture vessel, and a plurality of air holes 3 are arranged around the functional area 2.1 on the groove bottom of the accommodating groove 2, each air hole 3 is arranged to face outward of the accommodating groove 2 for generating an air wall around the functional area 2.1, and the shell 1 is provided with a gas supply equipment for providing high pressure clean air to each air hole 3.
[0029] In the embodiment, the air supply device can continuously provide clean compressed air after being powered on. The compressed air can form an annular air wall after being ejected through the air holes 3, so as to separate the space where the functional area 2.1 is located from the external environment. With the continuous ejection of the air flow in the air holes 3, the original air in the functional area 2.1 can also be taken away from the functional area 2.1 by the air flowing on the inner side of the air wall. The part of the clean air ejected from the air holes 3 is supplemented into the functional area 2.1, so that the functional area 2.1 is a sterile clean environment compared with the external environment.
[0030] Preferably, as shown in Figure 1 and Figure 7 The shell 1 is a cylindrical structure or a square structure.
[0031] Based on the above preferred embodiment, the air holes 3 are arranged upward along the axial direction of the containing groove 2, and the air wall formed by the high-speed air flow ejected from all the air holes 3 is annular. However, there is still a position above the containing groove 2 that cannot be covered by the air wall. Therefore, the improvement of the embodiment is that the shell 1 is provided with a top cover 4, and the top cover 4 is connected to the shell 1 through a movable rod. The top cover 4 has a covering state of covering the containing groove 2 and an opening state of being suspended above the containing groove 2. When the top cover 4 is in the opening state and moves upward to the limit position, the spacing width between the top cover 4 and the slot of the containing groove 2 is set to allow the culture vessel to pass through. The spacing between the top cover 4 and the slot of the containing groove 2 serves as a working channel for the operator to operate the culture vessel 16 in the containing groove 2. In the embodiment, the top of the annular air wall formed by the air holes 3 is aligned with the top cover 4. Therefore, the top cover 4, the air wall and the containing groove 2 can form a completely closed sterile space, which is isolated from the air in the external environment.
[0032] The specific width value of the spacing can be set according to the size of the existing culture vessel 16. The requirement of the spacing width can be simply obtained through a limited number of tests. Therefore, the specific value of the spacing width is not listed in detail.
[0033] In the above embodiment, for the partially open shell 1, the top cover 4 is not arranged to be capable of being suspended above the accommodating groove 2, and for this, the improvement of the present embodiment is that the air holes 3 arranged at the bottom of the accommodating groove 2 are arranged to be inclined in the vertical direction upwards and in the horizontal direction towards the functional area 2.1, that is, inclined in the horizontal direction towards the position where the center line of the accommodating groove 2 is located, so that the air flow emitted by each air hole 3 arranged in the circumferential direction can form a conical air wall converging inwards above the functional area 2.1, and the conical air wall can be enclosed on the functional area 2.1, so as to well block the convection of air in the external environment with the air in the functional area 2.1, and create a sterile environment. Compared with the above-mentioned top cover 4, although the space enclosed by the conical air wall in the present embodiment is smaller, the volume of the culture vessel that can be accommodated is limited, but the setting of the top cover 4 is omitted, so that the overall structure is more simple.
[0034] In the above embodiment, the greater the distance between the top cover 4 and the slot of the accommodating groove 2, the more convenient it is for the operator to operate each culture vessel 16 placed in the accommodating groove 2, but too large a distance will make the air wall blown by the air hole 3 poor in isolation effect, affecting the sterile isolation effect, on the contrary, the smaller the distance between the top cover 4 and the slot of the accommodating groove 2, the more conducive to keeping the environment in the accommodating groove 2 as a sterile environment, but too small a distance brings inconvenience to the operator's operation.
[0035] Therefore, based on one of the preferred examples of the above embodiment:
[0036] The movable rod is a vertically arranged damping telescopic rod, and the two ends of the damping telescopic rod are fixed with the top cover 4 and the shell 1 respectively. The damping telescopic rod is any damping telescopic rod that can be axially telescopic and provide damping force during telescopic process, which is a commercially available product, and the structure of the damping telescopic rod is not described in detail here. It should be understood that any damping telescopic rod that can be axially telescopic and provide damping force against external force during telescopic process belongs to the protection scope of the damping telescopic rod of the present embodiment.
[0037] Therefore, based on the second preferred example of the above embodiment:
[0038] The movable rod is a connecting arm 5 with multiple movable joints. Specifically, the connecting arm 5 is composed of multiple mutually hinged branch arms 5.1. Any two adjacent branch arms 5.1 are hinged to each other. The upper end of the first branch arm 5.1 is hinged to the top cover 4, and the lower end of the last branch arm 5.1 is hinged to the shell 1. The joints between any two adjacent branch arms 5.1, the first branch arm 5.1 and the top cover 4, and the last branch arm 5.1 and the shell 1 are movable joints. A friction damper is arranged on each movable joint to provide a damping force for the rotation of the movable joint. Thus, the top cover 4 can move relative to the shell 1 when subjected to an external force, and after the external force is removed, the top cover 4 is locked by the damping force provided by the friction damper, and finally the top cover 4 is suspended above the accommodating groove 2 of the shell 1. That is, the top cover 4 can be in a closed state of covering the slot of the accommodating groove 2, or in an open state of being suspended above the accommodating groove 2. Further, when the top cover 4 is in the open state, the distance between the top cover 4 and the slot of the accommodating groove 2 can be adjusted by adjusting the position of the top cover 4, so as to reduce the distance to improve the isolation effect of the air wall, or to increase the distance to facilitate the taking and placing or operation of the culture vessel 16.
[0039] In the embodiment, when the operator does not handle the culture vessel 16 for a long time, the operator can push the top cover 4 so that the top cover 4 moves to the Figure 1 closed state as shown, at which time the top cover 4 completely covers the slot of the accommodating groove 2, and the clean air pumped out of the air hole 3 can keep the accommodating groove 2 in a positive pressure, thereby completely isolating the air in the external environment from entering the accommodating groove 2 through the joint between the top cover 4 and the shell 4. When the operator needs to handle the culture vessel 16 in the accommodating groove 2, the operator only needs to pull the top cover 4 so that the top cover 4 switches to the open state, and the distance between the top cover 4 and the accommodating groove 2 can be adjusted according to different needs.
[0040] Preferably, the side wall of the top cover 4 is provided with an air outlet 6 for communicating the inner cavity formed by the top cover 4 and the accommodating groove 2. The air outlet 6 is covered with a filter screen. Thus, when the top cover 4 is in the closed state, the excess air can flow out of the air outlet 6 as the air supply device continuously charges the air into the accommodating groove 2, so as to ensure the positive pressure of the accommodating groove 2 and keep the accommodating groove 2 in a sterile environment.
[0041] Preferably, the connecting arm 5 comprises three branches 5.1, the upper end of the first branch 5.1 is hingedly connected to a protruding shaft on the outer sidewall of the top cover 4, the upper end of the second branch 5.1 is hingedly connected to the lower end of the first branch 5.1, the upper end of the last branch 5.1 is hingedly connected to the lower end of the second branch 5.1, and the lower end of the last branch 5.1 is hingedly connected to a protruding shaft on the outer sidewall of the shell 1. The hinge in the embodiment is also referred to as a pivot connection, and a friction damper is arranged at each hinge, so that when the shell 4 is subjected to an external force, the shell 1 can overcome the frictional resistance of the friction dampers and move, and when the external force is removed, the shell 1 can be kept in the current position by overcoming its own gravity by the frictional damping force provided by the friction dampers.
[0042] It should be understood that the friction damper is a commercially available product in the industry, and in the embodiment, the installation of each friction damper according to different types of friction dampers in the prior art is simple under the premise that the pivot connection is kept at the current position after rotating to any position by the friction damper. Therefore, the structure and installation of the friction damper are not described in detail.
[0043] Further, the air outlet 6 is a plurality of air outlets 6, and the plurality of air outlets 6 are uniformly arranged on the sidewall of the top cover 4 in the circumferential direction. Specifically, the top cover 4 comprises a top plate and an annular side plate, and the plurality of air outlets 6 are uniformly arranged on the side plate in the circumferential direction.
[0044] Based on the preferred active rod in the above embodiment, the active rod is symmetrically arranged along the longitudinal plane in which the central axis Z of the shell 1 is located.
[0045] Based on the preferred air supply device in the above embodiment, as shown in Figure 3 and Figure 4 , the inside of the shell 1 has a device mounting cavity 7, the air supply device comprises a fan 8 mounted in the device mounting cavity 7 and a motor 9 for driving the fan 8, the sidewall of the shell 1 is provided with an air inlet 10 communicating with the device mounting cavity 7, a plurality of partitions are arranged in the device mounting cavity 7, each partition separates the inner cavity of the device mounting cavity 7 to form an air flow channel and a motor cavity for accommodating the motor 9, the motor 9 is fixed in the motor cavity, the fan 8 is arranged in the air flow channel, and the output shaft of the motor 9 penetrates the motor cavity and is connected with the fan 8 in the air flow channel for driving the fan 8, the two ends of the air flow channel are respectively communicated with the air inlet 10 and the air hole 3, and the fan 8 drives the air in the air flow channel to flow towards the position where the air hole 3 is located.
[0046] Specifically, the equipment mounting cavity 7 includes a fan cavity and an intermediate cavity located between the fan cavity and the receiving groove 2. Multiple annular baffles are arranged radially outward within the intermediate cavity, dividing it into an S-shaped channel. The middle position of the fan cavity is connected to the middle position of the intermediate cavity through a central hole. The motor cavity is located in the middle position of the intermediate cavity. The motor 9 is located within the motor cavity, and its output shaft passes vertically through the central hole and is connected to the fan 8 within the fan cavity. The proximal end of the S-shaped channel is connected to the fan cavity through the central hole, and the distal end is connected to each air vent. The equipment mounting cavity 7 is equipped with an ultraviolet lamp 11 for providing ultraviolet light and a heating wire 12 for heating the air. The ultraviolet lamp 11 and the heating wire 12 are arranged sequentially along the airflow direction within the S-shaped channel. The ultraviolet lamp 11 should be positioned away from the air vents 3 to prevent some of the ultraviolet light generated by the ultraviolet lamp 11 from escaping through the air vents 3.
[0047] Furthermore, the housing 1 is provided with a power source for providing electrical energy to the heating wire 12 and the motor 9. This power source can be a battery or a power cord for electrically connecting to an external power source.
[0048] Preferably, a filter screen is provided on the air inlet 10 or in the airflow channel to filter the air drawn into the airflow channel, so that the air blown out from the air hole 3 is clean air at a constant temperature.
[0049] Based on the preferred embodiments described above, such as Figures 3-7 As shown, the culture vessel 16 for cell culture includes, but is not limited to, the bottle-shaped culture flask and the plate-shaped culture dish shown in the figure.
[0050] Preferably, the receiving tank 2 is provided with a shelf (not shown in the figure), which consists of two plates hinged together. A friction damper is provided between the two plates to increase frictional resistance. By swinging the two plates, the angle between the two plates can be adjusted. One plate of the shelf is placed in the receiving tank and fits against the bottom of the receiving tank 2, while the other plate is tilted. The culture vessel 16 is placed on the tilted plate, so that the culture vessel 16 can be placed in the receiving tank 2 in an inclined manner.
[0051] In this embodiment, as Figure 3As shown, the top cover 4 is in the closed state when descending to the slot opening of the accommodating groove 5 to form a better sterile closed environment. In order to further improve the sterilization effect of the closed environment, the improvement of the embodiment is that an auxiliary ultraviolet lamp 13 is arranged in the cavity formed by the top cover 4 and the accommodating groove 2, which is used for sterilizing the cavity. Specifically, the auxiliary ultraviolet lamp 13 is arranged on the inner side of the top cover 4 facing the shell 1. The shell 1 is provided with a power supply electrically connected with the auxiliary ultraviolet lamp 13, a sensor 14 for detecting the position of the top cover 4 and a controller 15. The auxiliary ultraviolet lamp 13 and the sensor 14 are respectively connected with the controller 15. In the embodiment, the sensor 14 is a position sensor 14 arranged on the lower end surface of the side wall of the top cover 4. When the top cover 4 is folded with the accommodating groove 2, the position sensor 14 is in contact with the groove side wall of the accommodating groove 2 and gives a detection signal. The controller 15 receives the detection signal given by the position sensor 14 and controls the auxiliary ultraviolet lamp 13 to be turned on. Conversely, when the lower end surface of the side wall of the top cover 4 is separated from the accommodating groove 2, the detection signal of the position sensor 14 disappears, and the controller 15 controls the auxiliary ultraviolet lamp 13 to be automatically turned off. The controller 15 can be arranged on the shell 1 or the top cover 4.
[0052] In the embodiment, the power supply for providing power for the auxiliary ultraviolet lamp 13 and the power supply for providing power for the heating wire 12 and the motor 9 can be the same power supply or different power supplies.
