Description

Technical Field

[0001] The utility model relates to the technical field of stem cell low-temperature refrigeration devices, in particular to a stem cell low-temperature refrigeration device for disease treatment. Background Art

[0002] Stem cells are a type of multipotent cell with the ability to self-renew. They are not fully differentiated and immature cells that have the potential to regenerate various tissues, organs and the human body. Due to their abilities to repair tissue damage, regulate immunity and have multidirectional differentiation potential, they have great application value in the medical field. After stem cells are separated and cultured from different human tissues, they are tested and identified, and then refrigerated so that they can be revived and re-infused into patients when clinically needed to achieve the purpose of treating diseases. During the refrigeration process of the container storing stem cells, condensation may be generated inside the refrigeration device, which accumulates inside the device, increases humidity and has an adverse effect on the stem cell storage environment. A Chinese patent discloses "a stem cell cryogenic refrigeration device for disease treatment," with application number 202321528833.6. The device is carried by lifting the handle and sealed at the top to enhance the low-temperature effect of the device and save energy. The device is also easy to carry, simple in structure, and portable. The chassis rotates, and the container storing stem cells needs to maintain stability during low-temperature transportation. While preventing the container from shaking randomly, proper rotation is used to prevent stem cell aggregation and sedimentation, thereby ensuring the activity of the stem cells stored therein. However, the device does not have any measures to address condensed water that may be generated inside, which may still affect the stem cell storage environment. Utility Model Content

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1-4 The embodiment of the present invention is a low-temperature cold storage device for stem cells used for disease treatment, which includes: an outer shell 1, which serves as the main structure of the entire cold storage device and provides protection and support for internal components. The outer shell 1 also has a certain thermal insulation performance to reduce the impact of external heat on the internal cold storage environment. A support plate 6 is fixedly connected to the side inner wall of the outer shell 1 for supporting and fixing other internal components (such as a placement shell 8, a cold air pipe 14, etc.). The support plate 6 is higher in the middle and lower in the front and rear, and is used for the natural flow and collection of condensed water. A positioning groove 9 is provided on the upper surface of the support plate 6 for positioning and fixing the placement shell 8. The side inner wall of the positioning groove 9 is fixedly connected to the placement shell 8 for accommodating and refrigerating a test tube containing stem cells. A cold cavity is provided inside the placement shell 8 for providing a stable low-temperature environment for the stem cells. A placement hole 10 is provided on the upper surface of the placement shell 8 for inserting a test tube containing stem cells.

[0024] The lower bottom wall of the shell 1 is fixedly connected to a refrigerator 13, which is used as the core component of the refrigeration device to generate low-temperature cold air through its internal refrigeration cycle. The output and input ends of the refrigerator 13 are fixedly connected to a cold air pipe 14 to ensure that the cold air can be evenly distributed inside the placement shell 8. The cold air pipe 14 passes through the support plate 6. The cold air pipe 14 is located inside the cold cavity. The cold air pipe 14 is wrapped around the outside of the placement hole 10 to ensure the refrigeration effect. The upper surface of the support plate 6 is provided with a guide groove 7 for collecting and guiding the condensed water generated during the refrigeration process. The guide groove 7 is higher on the right side and lower on the left side. The left surface of the shell 1 is fixedly connected to an output pipe 2 for discharging condensed water. The output pipe 2 is connected to the shell 1. The side surface of the output pipe 2 is provided with a valve 3 for controlling the discharge of the output pipe. The output pipe 2 is located on the left side of the guide groove 7 and is connected to each other.

[0025] An entrance is provided on the upper surface of the shell 1 for placing stem cells into the interior of the shell 1. A sealing cover 4 is threadedly connected to the side inner wall of the entrance for closing the opening part of the shell 1. A soft pad 11 is fixedly connected to the upper top wall of the sealing cover 4 for enhancing the stability of the test tube containing the stem cells. The sealing cover 4 is located directly above the placement shell 8. A vent 12 is provided on the lower surface of the shell 1 for promptly discharging the heat generated by the refrigerator 13 during operation to the outside of the device to maintain the working efficiency of the refrigerator and prevent heat accumulation from causing temperature increase. The vent 12 passes through the lower surface of the shell 1. The refrigerator 13 is located directly below the support plate 6. The lower surface of the shell 1 is fixedly connected to a pillar 5 for supporting the entire refrigeration device.

[0026] Working principle: The test tube containing stem cells is sealed and placed in the placement hole 10 of the placement shell 8, and the sealing cover 4 is connected to the inlet of the shell 1 by threading to achieve the closure of the shell 1. The soft pad 11 on the sealing cover 4 enhances the stability of the reagent after closure. Then the refrigerator 13 is started first. The refrigerator generates low-temperature cold air through its internal refrigeration cycle (such as compression-condensation-expansion-evaporation process). The cold air generated by the refrigerator 13 is transmitted through the cold air pipe 14. Since the cold air pipe 14 is wrapped around the outside of the placement hole 10 and is located in the cold cavity inside the placement shell 8, the cold air can be evenly distributed inside the placement shell 8, ensuring that each test tube The stem cells in the refrigerator can be affected by the same and stable low temperature, providing a stable low-temperature environment for the stem cells. During the refrigeration process, due to the decrease in temperature, water vapor in the air may condense into condensed water, and the condensed water is collected through the guide groove 7 set on the upper surface of the support plate 6. The design of the guide groove 7 (high on the right and low on the left) allows the condensed water to flow naturally to the left and finally be discharged out of the device through the output pipe 2. The valve 3 on the output pipe 2 can control the discharge of condensed water so that it can be cleaned when needed. The vent 12 set on the lower surface of the shell 1 allows the heat generated by the refrigerator 13 during operation to be discharged in time, ensuring that the refrigerator can continue to operate efficiently.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
