Description

Technical Field

[0001] The utility model relates to the technical field related to immune cell thawing, in particular to an immune cell thawing instrument. Background Art

[0002] Immune cells are an important component of the body's immune system. They are responsible for identifying and clearing antigenic foreign substances from the body, maintaining the body's physiological balance. To maintain the activity and function of immune cells, they are typically frozen and stored, and thawed when needed. Currently, immune cells are primarily thawed using the water bath method. This involves removing the frozen immune cells from a cryogenic environment and quickly placing them in a constant temperature water bath at 37°C to 42°C for rapid thawing. However, this thawing method, combined with direct hydrolysis, can easily lead to immune cell contamination.

[0003] Chinese patent authorization publication number: CN218932160U, authorization publication date: April 28, 2023, discloses a water bath cell thawing device, comprising: a frame; a float, the float being detachably mounted on the frame and having a placement hole provided on the float; and an oscillating device provided on the frame, the oscillating device being capable of generating mechanical oscillations to drive parallel oscillation of the cells to be thawed within the placement hole. A disadvantage of this utility model is that thawing by heating in a water bath can easily cause contamination of immune cells. Utility Model Content

[0004] The utility model aims to overcome the shortcoming of the prior art that the cell is easily contaminated by water source during water bath heating, and provides an immune cell thawing instrument which thaws the cell by heating a sealed space in a water bath.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An immune cell thawing instrument includes a constant temperature box and a storage frame. The constant temperature box is provided with a constant temperature cavity, and the constant temperature box is provided with a partition frame. The two ends of the partition frame are respectively connected to the two side surfaces of the constant temperature cavity on both sides. The partition frame is open at one end of the constant temperature box, and the storage frame is placed in the partition frame and is slidably connected to the partition frame.

[0007] The constant temperature chamber of the thermostat is used to add water. A partition frame is installed in the constant temperature chamber. Both ends of the partition frame are connected to the inner wall of the constant temperature chamber. After the connection, the two ends of the partition frame are closed. An opening is opened at one end of the thermostat, and the opening is connected to the partition frame. The partition frame is a square tube. A storage frame is placed in the partition frame. The immune cells to be thawed are placed in the storage frame. The water source in the thermostat ensures the thawing temperature. The water in the thermostat transfers heat to the partition frame to ensure that the air in the partition frame is at the same temperature as the water source in the thermostat. The heat transfer through water can ensure that the heat increase is more stable and the heating process is more uniform. More immune cell bags can be placed in the storage frame. The immune cell bags are not directly dissolved in water and do not contact each other, reducing the possibility of contamination, thereby achieving the purpose of thawing by heating the sealed space in a water bath.

[0008] Preferably, a top cover is provided on the top of the thermostat, and the top cover is detachably connected to the thermostat. A heater is installed in the thermostat chamber, a thermostat is installed in the thermostat chamber, and a wristband is installed on the top cover. The heater installed in the thermostat heats the water source to increase the water temperature. At the same time, a thermostat is installed in the thermostat chamber to control the water temperature and ensure the stability of the water temperature, so that the water temperature is kept at a constant temperature and can be heated better. At the same time, a top cover is installed on the top surface of the thermostat to reduce heat dissipation and better ensure the stability of the water temperature. A wristband is installed on the top cover for removing the top cover. This design facilitates reducing heat dissipation.

Sliding blocks are installed on the upper and lower sides of the storage frame, and a sliding groove is provided on the partition frame. The storage frame is slidably connected to the partition frame through the cooperation of the sliding block and the sliding groove. The storage frame is placed in the partition frame and can be pushed and pulled from the open end of the partition frame. The partition frame is slidably connected to the partition frame through the cooperation of the sliding groove and the sliding block. The pull ring is pulled out to pull out the storage frame to place the immune cell bag. A baffle is installed at one end of the storage frame to close the open end of the partition frame, reducing heat loss in the partition frame to ensure that the immune cell bag in the partition frame is fully thawed. The U-shaped storage frame places the immune cell bag from the open end. After the placement is completed, the storage frame is pushed into the partition frame, and then the immune cell bag is thawed. The immune cell bag only receives air heat in the storage frame, and its position is relatively fixed. At the same time, it does not contact other immune cell bags. Therefore, more immune cell bags can be placed for thawing. This design can thaw more immune cell bags at the same time.
