Description

Technical Field

[0001] This utility model relates to the field of heating technology, specifically a heating device for a cell resuscitation instrument. Background Technology

[0002] An important way to preserve existing cell resources for a long time is cryopreservation (liquid nitrogen). When needed, the frozen cells are taken out and thawed. Currently, the best method for cell thaw is to thaw rapidly at 37°C to avoid water seeping into the cells due to slow thawing, which can cause intracellular recrystallization and damage to the cells. Various cell thaw instruments are available on the market.

[0003] For example, existing patent application number 201920814142.X belongs to the field of cell resuscitation technology and discloses a cell resuscitation device, which includes a main body and a top cover. A working chamber is provided inside the main body, and the top cover is connected to the main body to open or close the working chamber. The cell resuscitation device also includes: an oscillation mechanism disposed within the working chamber; a heated tray connected to the oscillation mechanism, the heated tray having multiple placement slots for placing cell cryopreservation containers; and a hot air heating device disposed within the working chamber, configured to blow hot air onto the heated tray and the cell cryopreservation containers. The oscillation mechanism drives the heated tray to shake, ensuring uniform heating of the cells within the cell cryopreservation containers, achieving rapid thawing; the heated tray can hold multiple cell cryopreservation containers at a time.

[0004] However, taking the aforementioned cell resuscitation device as an example, when heating the cell cryopreservation container, it is usually done in an atmospheric environment, and the heated atmosphere may even come into direct contact with the cell cryopreservation container, increasing the risk of contamination of the cell solution inside the cell cryopreservation container.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-6 As shown, this utility model provides a technical solution for a heating device for a cell resuscitation instrument:

[0025] Example 1: Multiple universal joints 6 capable of multi-directional movement are fixedly installed at the bottom of the shaking box 3. A telescopic rod 5 capable of extension and retraction is fixedly installed between the bottom end of the universal joint 6 and the bottom of the inner cavity of the equipment housing 1. The shaking box 3, supported by the telescopic rod 5 and the universal joint 6, can move in multiple directions, which meets the need of the vibrator 4 to apply vibration force to the shaking box 3. Furthermore, the elastic element 24 fixedly installed between the outer side of the shaking box 3 and the equipment housing 1 can deform, and the vibration of the shaking box 3 is not affected by the elastic element 24.

[0026] Multiple placement slots 9 are provided on the top of the shaking box 3. The heat exchanger 10 at the bottom of the placement slot 9 is fixedly connected to the top of the inner cavity of the shaking box 3. After the cell cryopreservation container is inserted into the heat exchanger 10 through the placement slot 9, the top cover 2 is closed, and the hot air blower 21 fixedly installed on one side of the equipment shell 1 is controlled to work. The normally closed end of the three-way valve 23 is controlled to open. Since the normally closed end of the three-way valve 23 fixedly installed at the air inlet end of the hot air blower 21 is fixedly installed between the three-way valve 23 and the equipment shell 1, the working hot air blower 21 draws air from the inside of the equipment shell 1 through the three-way valve 23 and the air extraction pipe 26. At this time, the blocking frame 12 does not enter the air guiding channel 16 formed on the heat exchanger 10, and the notch 25 opened on one side of the shaking box 3 is set at the bottom of the elastic member 24. Therefore, the inside of the equipment shell 1 is in a state of vertical communication at this time.

[0027] Therefore, the hot air blower 21 works to extract the gas inside the equipment casing 1. The hot air blower 21 discharges the gas through the normally open end of the three-way valve 27 fixedly installed at the outlet end.

[0028] Additionally, a temperature sensor 7 and a pressure sensor 8 are fixedly installed on one side inside the equipment housing 1. The temperature sensor 7 detects the temperature inside the equipment housing 1, and the pressure sensor 8 detects the air pressure inside the equipment housing 1. Both the temperature sensor 7 and the pressure sensor 8 are electrically connected to the human-machine interface device. As the hot air blower 21 operates for longer, the air pressure inside the equipment housing 1 decreases. Based on the feedback from the pressure sensor 8, the human-machine interface device controls the hot air blower 21 to stop operating and controls the normally closed end of the three-way valve 23 to close after the air pressure inside the equipment housing 1 drops to a certain value.

[0029] Multiple short pipes 19 are fixedly installed on one side of the equipment casing 1. A three-way valve 18 is fixedly installed on one side of the distribution box 17, which is fixedly connected to the multiple short pipes 19. The normally closed end of the three-way valve 18 is connected to the inert gas supply system. After the hot air blower 21 stops working, the normally closed end of the three-way valve 18 is opened to allow inert gas to enter the interior of the equipment casing 1 and fill the interior of the equipment casing 1. After a period of time, the three-way valve 18 is stopped working. Through the combination of the hot air blower 21, the distribution box 17, and the multiple short pipes 19, the gas inside the equipment casing 1 can be replaced with inert gas, reducing the contact between the atmosphere and the cell cryopreservation container during heating, reducing unnecessary reactions of the cell solution in the cell cryopreservation container during heating and thawing, and ensuring the quality of cell thawing.

[0030] Example 2: The feeding assembly is controlled to perform its first operation. The pneumatic cylinder 15, fixedly installed inside the shaking box 3, retracts for the first time. Since multiple blocking brackets 12 are fixedly installed on the top of the transmission plate 13 inside the shaking box 3, and the pneumatic cylinder 15 is fixedly installed between the transmission plate 13 and the shaking box 3, the vertical position of the transmission plate 13 and the blocking brackets 12 is controlled by the pneumatic cylinder 15. Multiple guide brackets 14 passing through the transmission plate 13 are fixedly connected to the shaking box 3. Under the action of the multiple guide brackets 14, the transmission plate 13 can only move upwards... During the downward movement, the pneumatic cylinder 15 drives the transmission plate 13 to move upward a certain distance, and the multiple blocking brackets 12 move upward a certain distance. Since the multiple blocking brackets 12 correspond one-to-one with the multiple air guide channels 16 formed at the bottom of the multiple heat exchange components 10, the upward-moving multiple blocking brackets 12 enter the interior of the multiple air guide channels 16, causing the air guide channels 16 to be blocked. In addition, the elastic element 24 fixedly installed between the shaking box 3 and the equipment shell 1 is set at the top of the notch 25. At this time, the top of the inner cavity of the equipment shell 1 and the interior of the shaking box 3 are in a state of separation.

[0031] A liquid storage tank is formed on the heat exchanger 10, and the liquid storage tank stores a heat-conducting medium. The hot air blower 21 is controlled to work, and the normally closed end of the three-way valve 27 is controlled to open. At this time, the hot air blower 21 draws air for heating through the normally open end of the three-way valve 23. The hot air blower 21 delivers hot air to the three-way valve 27. The connecting pipe 20 in the air guide assembly between the air outlet end of the hot air blower 21 and the shaking box 3 is fixedly connected to one side of the shaking box 3. Multiple deformable hoses 28 are fixedly installed on one side of the connecting pipe 20. The diversion box 22, which is fixedly connected between the multiple hoses 28, is fixedly connected to the normally closed end of the three-way valve 27. The hot air blower 21 delivers hot air into the shaking box 3. During the flow of hot air, the heat-conducting medium inside the liquid storage tank is heated. The heat-conducting medium exchanges heat with the cell cryopreservation container and heats the cell solution in the cell cryopreservation container, ensuring that the cell cryopreservation container is heated evenly.

[0032] After heat exchange, the gas flowing from inside the shaking box 3 enters the distribution box 17 through the notch 25 and multiple short pipes 19, and is finally discharged through the normally open end of the three-way valve 18 that is fixedly connected to the distribution box 17.

[0033] Example 3;

[0034] After a period of time in Example 2, the vibrator 4 is controlled to work. The vibrator 4 causes the shaking box 3 to vibrate as a whole, and the cell cryopreservation container to shake, so as to shake the cell solution inside the cell cryopreservation container, ensuring the speed of heat flow inside the cell cryopreservation container and improving the speed of cell revival inside the cell cryopreservation container.

[0035] Finally, after opening the top cover 2, the control cylinder 15 performs a second operation. At this time, multiple blocking racks 12 move upward to push out the cell cryopreservation container, making it convenient for staff to retrieve the cell cryopreservation container.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
