Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, and more specifically, to a blood cell circulation culture device. Background Technology

[0002] Cell culture is a technique that simulates the physiological environment in vivo by taking living cells from a living organism and placing them in a suitable artificial environment to allow them to grow, multiply, and maintain specific functions. It is one of the fundamental technologies in modern biology, medicine, and biotechnology, and is widely used in basic research, drug development, disease model construction, biopharmaceuticals, tissue engineering, and many other fields.

[0003] In modern biomedical research and cell therapy, blood cell culture is crucial. Currently, most blood cell culture devices employ static culture methods, placing blood cells in a culture medium within a container where they grow in a relatively static environment. However, human blood is constantly circulating, and the static culture environment differs significantly from the actual blood flow environment in the human body. This difference prevents blood cells from obtaining physiological conditions such as substance exchange and shear forces similar to those in vivo during culture, thus affecting their growth, differentiation, metabolism, and other physiological functions. Consequently, the cultured blood cells exhibit significant differences in biological characteristics and function compared to in vivo blood cells, leading to impaired cell function or low culture efficiency. Therefore, there is an urgent need for a circulating culture device that can simulate the human blood flow environment to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a blood cell circulation culture device that precisely simulates the blood flow environment in the human body by driving the culture medium to circulate, thereby providing blood cells with growth conditions closer to those in the body and improving the quality and effect of blood cell culture.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] Example:

[0032] like Figures 1 to 8 As shown, a blood cell circulation culture device includes an insulated box 1 and a base 3. The insulated box 1 is installed on the upper side of the base 3, and a circulation culture mechanism 7 is provided inside the insulated box 1.

[0033] The circulating culture mechanism 7 includes a protective sleeve 71, a circulating hose 73, a peristaltic pump 74, and a spiral culture tube 711. The protective sleeve 71 is located inside the insulated chamber 1. A transparent spiral culture tube 711 is located inside the protective sleeve 71, with its upper and lower ends extending from the upper and lower ends of the protective sleeve 71. Both ends of the spiral culture tube 711 are connected to the transparent circulating hose 73 via sealing connectors 79. The peristaltic pump 74 is installed on the right side of the insulated chamber 1 via a fixing bracket 75. The right section of the circulating hose 73 is detachably wound around the peristaltic pump 74. This design solves the problem that existing blood cell culture devices use static culture methods, which cannot simulate the human blood flow environment, thus affecting the physiological functions of cell growth, differentiation, and metabolism. This results in cultured blood cells having significant differences in biological characteristics and functions compared to in vivo blood cells, leading to impaired cell function or low culture efficiency. This device drives the circulation of the culture medium to accurately simulate the human blood flow environment, providing blood cells with growth conditions closer to those in vivo, thereby improving the quality and effectiveness of blood cell culture.

[0034] In this embodiment, two sets of brackets 72 are provided on the inner left side wall of the insulated box 1, and the protective sleeve 71 is detachably clamped on the two sets of brackets 72.

[0035] The support frame 72 consists of a fixed support rod 721 and a U-shaped hanger 722. One end of the fixed support rod 721 is fixedly connected to the inner wall of the insulation box 1, and the other end is equipped with a U-shaped hanger 722. The specifications of the U-shaped hanger 722 are compatible with the specifications of the protective sleeve 71. Two sets of positioning baffles 76 are provided on the annular surface of the protective sleeve 71, and the diameter of the positioning baffles 76 is the same as the diameter of the U-shaped hanger 722. This design, through the two sets of supports 72, facilitates the clamping and fixing of the protective sleeve 71, making it easy to fix the protective sleeve 71 inside the insulation box 1.

[0036] In this embodiment, a hose valve 78 is installed near the upper end of the circulation hose 73. The hose valve 78 facilitates the control of the opening and closing of the circulation hose 73 and can also adjust the flow rate of the culture medium in the circulation hose 73.

[0037] In this embodiment, an air inlet 710 communicating with the interior is provided on the upper annular surface of the spiral culture tube 711, with the upper end of the air inlet 710 inclined outward. The air inlet 710 facilitates the entry of air into the spiral culture tube 711, providing the necessary oxygen for cell culture in the culture medium.

[0038] In this embodiment, the protective sleeve 71 is made of medical transparent plastic, which makes it easy to directly observe the flow of culture medium in the internal culture tube through the protective sleeve 71. Multiple sets of through grooves 77 are evenly opened on its annular surface, which makes it easy for hot air in the heat preservation box 1 to enter the interior of the protective sleeve 71 and fully contact the spiral culture tube 711 to heat the culture medium in the spiral culture tube 711.

[0039] In this embodiment, an openable and closable insulated box door 2 is installed on the front side of the insulated box 1. The insulated box door 2 can seal the insulated box 1, which can effectively reduce the heat exchange between the inside of the insulated box 1 and the external environment and reduce the heat loss rate. At the same time, the openable and closable insulated box door 2 allows the staff to easily operate and maintain the circulating culture mechanism 7 inside the insulated box 1.

[0040] In this embodiment, a partition 11 is provided inside the base 3. A constant-temperature electric heater 13 is installed in the right area of ​​the partition 11, and a blower 9 is installed in the left area of ​​the partition 11. A ventilation slot 12 is provided on the partition 11, and the air outlet of the blower 9 is connected to the ventilation slot 12. A heat dissipation vent 6 is provided on the left side of the base 3 corresponding to the blower 9, and multiple sets of air outlets 8 are evenly provided on the upper surface of the base 3. This design, through the use of the constant-temperature electric heater 13 and the blower 9, facilitates the heating of the internal space of the insulation box 1, so that the culture medium in the circulating culture mechanism 7 can be maintained at a suitable temperature.

[0041] In this embodiment, a main controller 10 is provided on the front side of the blower 9, and a control panel 4 is mounted on the front surface of the base 3. All electrical components are connected to the main controller 10 through wires, and the main controller 10 is electrically connected to the control panel 4 through wires.

[0042] In this embodiment, an adjustable exhaust port 5 is installed on the top of the insulated box 1 to maintain the stability of the pressure inside the box and ensure the normal operation of the device.

[0043] The working principle of this blood cell circulation culture device:

[0044] In practical use, when blood cells need to be cultured, first connect one end of the circulating tubing 73 to the lower end of the spiral culture tube 711 via the sealing connector 79. Then close the tubing valve 78 on the circulating tubing 73 and add the culture medium containing blood cells into the spiral culture tube 711 through the upper port. Next, connect the other end of the circulating tubing 73 to the upper port of the spiral culture tube 711 via the sealing connector 79. Then open the incubator door 2, clamp the protective sleeve 71 onto the support 72 to fix the protective sleeve 71, and then wrap the right half of the circulating tubing 73 around the peristaltic pump 74 and open the tubing valve 78. The operating parameters of the peristaltic pump 74, blower 9, and constant-temperature electric heater 13 are adjusted via control panel 4. Then, blower 9 and constant-temperature electric heater 13 are started, setting the heating temperature of constant-temperature electric heater 13 to 37 degrees Celsius. The constant-temperature electric heater 13 generates heat, which is then blown by blower 9 through air outlet 8 into the insulation chamber 1 to heat the culture medium, maintaining the internal temperature of the insulation chamber 1 at 37 degrees Celsius. Next, peristaltic pump 74 is started, driving the culture medium to circulate in the spiral culture tube 711 and circulating tubing 73, simulating the blood flow environment in the human body.

[0045] Once the culture time has reached the preset value or the cell culture has achieved the expected results, press the stop button on control panel 4 to turn off all electrical components. Open the incubator door 2, detach the culture container from the circulation tubing 73, and remove the cultured blood cells for subsequent experiments or analysis.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
