Description

Technical Field

[0001] The utility model relates to the technical field of stem cell storage, in particular to a stem cell storage device. Background Art

[0002] Stem cells are a type of multipotent cells with the ability to self-replicate. Under certain conditions, they can differentiate into multiple functional cells. According to the developmental stage of stem cells, they are divided into embryonic stem cells and adult stem cells. According to the developmental potential of stem cells, they are divided into three categories: totipotent stem cells, pluripotent stem cells and unipotent stem cells. Stem cells are a type of cell that is not fully differentiated and not yet mature. They have the potential to regenerate various tissues, organs and the human body. They are called "universal cells" in the medical field. Stem cell storage devices are commonly used instruments in the process of stem cell storage. Most of the existing stem cell storage devices are filled with thermal insulation cotton between the outer sleeve and the internal storage cavity, which mainly plays a role in preventing the rapid loss of internal liquid nitrogen temperature. However, the existing stem cell storage devices do not have corresponding buffer devices. When the stem cell storage device is hit or accidentally dropped during transportation, it is easy to cause the test tubes used for stem cell storage to be vibrated and broken or damaged. Therefore, a stem cell storage device is designed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a stem cell storage device, comprising: an outer sleeve 1 which is hollow inside and has arc-shaped upper and lower ends, a second interlayer 2 is connected inside the outer sleeve 1, water is filled between the second interlayer 2 and the outer sleeve 1, a third interlayer 3 is connected inside the second interlayer 2, a pearl cotton pad 4 is connected between the third interlayer 3 and the second clamp 2, the lower end of the pearl cotton pad 4 is paved on the lower surface of the third interlayer 3, the upper end of the pearl cotton pad 4 is array-shaped and sleeved on the outer surface of the third interlayer 3, and the third The interior of the interlayer 3 is connected to a placement cavity 5 which is hollow inside and open at the upper end. The space between the placement cavity 5 and the third interlayer 3 is filled with helium. The upper opening of the placement cavity 5 extends to the upper end of the outer sleeve 1. A ring-shaped array of placement openings 6 for picking up rods are provided around the upper end of the opening of the placement cavity 5. A plug 7 is provided at the upper end of the placement cavity 5. The upper end diameter of the plug 7 is the same as the outer diameter of the upper end opening of the placement cavity 5. The lower end diameter of the plug 7 is the same as the inner diameter of the upper end opening of the placement cavity 5. The plug 7 is filled with thermal insulation cotton.

[0024] When in use, liquid nitrogen is poured into the placement cavity 5, and then the stem cell storage rack is placed into the placement cavity 5, and the taking rod at the upper end of the stem cell storage rack is inserted into the taking rod placement port 6, and then the plug 7 is inserted into the upper end of the placement cavity 5. When the stem cell storage device is hit or falls, it will first hit the outside of the outer sleeve 1. After the water filled between the second interlayer 2 and the outer sleeve 1 is used for shock absorption, a part of the impact force is transmitted to the second interlayer 2, and then the remaining impact force is transmitted to the outside of the pearl cotton pad 4, and then transmitted to the inside of the third interlayer 3 after buffering, thereby reducing the impact force on the internal stem cell storage tubes and preventing the stem cell storage tubes from being damaged by excessive force. The helium filled between the placement cavity 5 and the third interlayer 3 can have the effect of blocking the temperature.

[0025] like Figure 1 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a temperature detector 21 is internally connected to the upper end of the plug 7, and the temperature detection probe of the temperature detector 21 is located at the lower end of the plug 7.

[0026] From the analysis of the above structure, it can be seen that after the plug 7 is inserted into the upper opening of the placement cavity 5, the temperature detection probe of the temperature detector 21 will detect the temperature inside the placement cavity 5, and then the internal temperature will be displayed inside the temperature detector 21 on the upper surface of the plug 7.

[0027] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the picking rod placement port 6 extends to the lower end inside the upper opening of the placement cavity 5, and a picking rod clamping port 22 is provided on the outer side of the plug 7 at a position opposite to the picking rod placement port 6. The lower surface of the upper end of the plug 7 is also provided with a picking rod clamping port 22 at a position opposite to the picking rod placement port 6.

[0028] From the analysis of the above structure, it can be known that the taking rod at the upper end of the stem cell placement rack is inserted into the upper opening of the placement cavity 5 and the inside of the taking rod placement port 6, and then the taking rod clamping port 22 on the outside of the plug 7 is aligned with the taking rod at the upper end of the stem cell placement rack and inserted, so that the taking rod at the upper end of the stem cell placement rack can be fixed to prevent the stem cell placement rack from shaking when it is taken away for transportation.

[0029] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the length of the plug 7 is longer than the internal length of the upper opening of the placement cavity 5, and the lower end of the plug 7 is chamfered around.

[0030] Analysis of the above structure shows that the length of the plug 7 is longer than the internal length of the upper opening of the placement cavity 5, which can fix the position of the stem cell placement rack and reduce the swing of the stem cell placement rack during movement. The chamfered corners around the lower end of the plug 7 can provide a certain guide for the insertion of the plug 7, making it easier to insert the plug 7.

[0031] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a sealing ring is connected around the lower surface of the upper end of the plug 7 and around the upper end opening of the placement cavity 5.

[0032] Analysis of the above structure shows that after the plug 7 is inserted into the upper opening of the placement cavity 5, the lower surface of the upper end of the plug 7 and the sealing ring at the upper opening of the placement cavity 5 will fit each other, thereby improving the sealing performance and preventing liquid nitrogen from flowing out through the connection.

[0033] like Figure 1-3 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a handle 23 is connected to the upper surface of the plug 7, and a handle seat 24 is connected to the upper end of the outer side of the outer sleeve 1 in a ring array, and a lifting handle 25 is rotatably connected inside the handle seat 24.

[0034] From the analysis of the above structure, it can be known that when the plug 7 is pulled out, the handle 23 can be held and pulled upwards to facilitate the removal of the plug 7. When the internal liquid nitrogen needs to be poured out or transported, the stem cell storage device can be transported by holding the lifting handle 25.

[0035] like Figure 1-3 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer sleeve 1 and the second interlayer 2 and the third interlayer 3 are all made of plastic materials, and the placement cavity 5 is made of stainless steel.

[0036] From the analysis of the above structure, it can be known that the outer sleeve 1 and the second interlayer 2 and the third interlayer 3 are all made of plastic materials. When impacted, they will rebound to prevent deformation and cushion the impact.
