Description

Technical Field

[0001] The utility model relates to the technical field of reagent kits, in particular to a stem cell detection reagent kit. Background Art

[0002] Stem cell detection is an important link to ensure the quality and safety of stem cells. Its process involves multiple steps and various technical methods. Stem cell detection mainly includes four links: access inspection, quality inspection, release inspection, and review inspection. A stem cell detection reagent kit is a kit used to detect specific properties or functions of stem cells. They usually contain a series of optimized reagents and tools so that researchers can efficiently conduct research and analysis on stem cells.

[0003] The utility model patent with the publication number of CN219524646U discloses a stem cell detection reagent kit, which can not only place reagent tubes of different lengths in the reagent kit, improving the convenience of using the placement box, but also prevent the second placement plate from moving, improving the stability of using the reagent kit. It can also prevent the reagent tubes from colliding with the first placement plate and breaking, improving the safety of using the reagent kit.

[0004] Stem cell detection reagents usually need to be stored under specific temperature conditions to maintain the activity and stability of their internal components. Generally, the temperature of the storage environment should not be too high. Although the above reagent kit can play a role in placing and preventing collisions of reagent tubes, the temperature inside the box will change synchronously with the environment. Especially for some reagents that need to be stored refrigerated, it is difficult to play an effective storage role. When experimenters temporarily store reagents in this box for transfer, the activity and stability of the reagents may be damaged due to the increase in temperature in a relatively short time. Therefore, in view of the above problems, a stem cell detection reagent kit is proposed. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is to provide a stem cell detection kit. In the kit, an ice-water mixture or a cold source medium with a relatively low temperature is placed in a heat preservation box, which can quickly reduce the temperature of the reagent tube storage tube through heat exchange. When the reagent tube is placed in the reagent tube storage tube, the two will be in close contact, thereby reducing the temperature of the reagent in the reagent tube. Moreover, the cold source medium does not directly contact the reagent tube and will not wet the reagent tube to cause damage to the label on it. In addition, the reagent tube storage tube of the corresponding model can be selected according to the model of the reagent tube and installed on the movable mounting plate, making the overall structure have a certain applicability. Particularly, a plurality of heat exchange fins are arranged on the surface of the heat exchange tube, which can further improve the heat exchange efficiency and ensure the refrigeration effect, solving the technical problem in the prior art that when an experimenter temporarily stores a reagent using a test kit for transfer, the activity and stability of the reagent may be damaged due to the increase in temperature in a relatively short time, making it difficult for the reagent to function properly.

[0006] The technical solution adopted by the embodiment of the present application to solve its technical problem is:

[0007] A stem cell detection kit includes a heat preservation box for containing a liquid medium, and a box cover is provided on it. A movable mounting plate is clamped on the heat preservation box, and a plurality of reagent tube storage tubes are threadedly connected thereto. Among them, the reagent tube storage tube includes a heat exchange tube, a threaded tube is connected to the top of the heat exchange tube, a hexagonal ring is fixedly sleeved on the heat exchange tube at a position close to the threaded tube, and a plurality of vertically arranged heat exchange fins are fixedly connected to the outer wall of the heat exchange tube.

[0008] Through the above structural form, an ice-water mixture or a cold source medium with a relatively low temperature is placed in the heat preservation box, which can quickly reduce the temperature of the reagent tube storage tube through heat exchange. When the reagent tube is placed in the reagent tube storage tube, the two will be in close contact, thereby reducing the temperature of the reagent in the reagent tube and extending its effective time.

In addition, the reagent tube storage tube of the corresponding model can be selected according to the model of the reagent tube and installed on the movable mounting plate, making the overall structure have a certain applicability. Particularly, a plurality of heat exchange fins are arranged on the surface of the heat exchange tube, which can further improve the heat exchange efficiency and ensure the refrigeration effect.

[0009] In a possible implementation manner, a plurality of through holes are provided on the movable mounting plate, and a plurality of threaded cylinders communicating with the through holes are fixedly arranged on the upper end surface thereof. Among them, the inner walls of the threaded cylinders and the through holes are provided with continuous internal threads that match the thread size of the threaded tube.

[0010] Through the above structural form, the length of the internal thread that can play a connecting role by the threaded cylinder can be increased, ensuring the stability of the connection between the movable mounting plate and the reagent tube storage tube.

[0011] In a possible implementation manner, two symmetrically arranged protective baffles are snap-fitted in the insulation box, and when the movable mounting plate is snap-fitted on the insulation box, the reagent tube storage tube mounted on the movable mounting plate is located within the protective baffles.

[0012] Through the above structural form, the protective baffles can play a role in protecting the reagent tube storage tube, avoiding the situation where when ice cubes are placed in the insulation box and it is moved, the ice cubes impact the heat exchange fins during shaking and cause them to deform.

[0013] In a possible implementation manner, the protective baffle includes a folding plate, the height of which is numerically equal to the opening depth of the insulation box, and a plurality of exchange holes are arranged in an array on the folding plate.

[0014] Through the above structural form, the exchange holes can play a role in allowing ice water to pass through while blocking and separating the ice cubes.

[0015] In a possible implementation manner, snap-fitting protrusions are fixedly arranged on both sides of the folding plate, corresponding slots are opened on the insulation box at corresponding positions, and the width of the slots is numerically equal to the thickness of the folding plate.

[0016] Through the above structural form, the detachable connection between the overall protective baffle and the insulation box can be realized, and the protective baffle can be disassembled and replaced.

[0017] In a possible implementation manner, a drain port is opened on the side wall of the insulation box, the bottom of the drain port is flush with the bottom surface of the inner space of the insulation box, and a tightly connected airtight plug is inserted into the drain port.

[0018] Through the above structural form, the water in the insulation box can be drained through the drain port, facilitating the replacement of the water for refrigeration.

[0019] In a possible implementation manner, positioning grooves are opened on both sides of the movable mounting plate, and positioning posts with dimensions matching those of the positioning grooves are fixedly arranged on both sides of the opening of the insulation box.

[0020] Through the above structural form, when the movable mounting plate is lapped on the insulation box and the positioning groove and the positioning post are snap-fitted with each other, the position of the movable mounting plate can be fixed, and thus the position of the reagent tube storage tube can be indirectly fixed.

[0021] In a possible implementation manner, bolts are fixedly connected to both sides of the lower end surface of the box cover, through holes through which the bolts can pass are opened on both sides of the insulation box, and locking wheels are threadedly connected to the bolts.

[0022] With the above structural form, when the box cover is placed on the insulation box and the locking wheel is tightened, the fixed connection between the two can be achieved.

[0023] In summary, the utility model includes the following beneficial technical effects:

[0024] An ice-water mixture or a cold source medium with a relatively low temperature is placed in the insulation box. It can rapidly reduce the temperature of the reagent tube storage tube through heat exchange. When the reagent tube is placed in the reagent tube storage tube, the two will be in close contact, thereby reducing the temperature of the reagent in the reagent tube and extending its effective time. Moreover, in the above process, the cold source medium does not directly contact the reagent tube and will not wet the reagent tube to cause damage to the label on it;

[0025] In addition, the reagent tube storage tube of the corresponding model can be selected according to the model of the reagent tube and installed on the movable mounting plate, making the overall structure have a certain applicability. Particularly, a number of heat exchange fins are arranged on the surface of the heat exchange tube, which can further improve the heat exchange efficiency and ensure the refrigeration effect.

[0032] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0033] AsFigure 1 - Figure 3 As shown in Figure 3 , a stem cell detection kit provided in this embodiment includes a heat preservation box 1 for containing a liquid medium, and a box cover 4 is provided on its upper cover. An active mounting plate 2 is snap-connected to the heat preservation box 1, and a number of reagent tube storage tubes 3 are threadedly connected thereto. With the above structural form, an ice-water mixture or a cold source medium with a lower temperature is placed in the heat preservation box 1, which can quickly reduce the temperature of the reagent tube storage tubes 3 through heat exchange. When the reagent tubes are placed in the reagent tube storage tubes 3, the two will be in close contact, thereby reducing the temperature of the reagents in the reagent tubes and extending their effective time. Moreover, in the above process, the cold source medium does not directly contact the reagent tubes and will not wet the reagent tubes to cause damage to the labels thereon. In addition, the corresponding model of the reagent tube storage tube 3 can be selected according to the model of the reagent tube and installed on the active mounting plate 2, making the overall structure have a certain applicability.

[0034] Among them, the reagent tube storage tube 3 includes a heat exchange tube 31, a threaded tube 32 is connected to the top end of the heat exchange tube 31, a hexagonal ring 33 is fixedly sleeved on the heat exchange tube 31 at a position close to the threaded tube 32, and a number of vertically arranged heat exchange fins 34 are fixedly connected to the outer wall of the heat exchange tube 31. A number of heat exchange fins 34 are arranged on the surface of the heat exchange tube 31, which can further improve the heat exchange efficiency and ensure the refrigeration effect.

[0035] As Figure 3 shown in Figure 3 , a number of through holes are provided on the active mounting plate 2, and a number of threaded cylinders 21 communicating with the through holes are fixedly provided on its upper end surface. Among them, the inner threads of the threaded cylinders 21 and the inner walls of the through holes are continuous and have the same thread size as the threaded tube 32. With the above structural form, the length of the inner thread that plays a connecting role can be increased by the threaded cylinder 21 to ensure the stability of the connection between the active mounting plate 2 and the reagent tube storage tube 3.

[0036] As Figure 4 shown in Figure 4 , two symmetrically arranged protective baffles 5 are snap-connected in the heat preservation box 1, and when the active mounting plate 2 is snap-connected to the heat preservation box 1, the reagent tube storage tubes 3 installed on the active mounting plate 2 are located inside the protective baffles 5. With the above structural form, the protective baffles 5 can play a role in protecting the reagent tube storage tubes 3, avoiding the situation that when ice cubes are placed in the heat preservation box 1 and it is moved, the ice cubes hit the heat exchange fins 34 during the shaking process and cause them to deform.

[0037] Among them, the protective baffle 5 includes a folding plate 51, the height of which is numerically equal to the opening depth of the heat preservation box 1, and a number of exchange holes 52 are provided in an array on the folding plate 51. With the above structural form, the exchange holes 52 can play a role in allowing ice water to pass through while blocking and separating the ice cubes.

[0038] In addition, clamping protrusions 53 are fixedly arranged on both sides of the folding plate 51, slots 13 are formed at corresponding positions on the heat preservation box 1, and the width of the slot 13 is numerically equal to the thickness of the folding plate 51. Through the above structural form, the detachable connection between the overall protective baffle 5 and the heat preservation box 1 can be realized, and the protective baffle 5 can be disassembled and replaced.

[0039] As Figure 1 shown, a drain port 11 is formed on the side wall of the heat preservation box 1, the bottom of the drain port 11 is flush with the bottom surface of the inner space of the heat preservation box 1, and a tightly connected airtight plug 111 is inserted in the drain port 11. Through the above structural form, the water in the heat preservation box 1 can be discharged through the drain port 11, which is convenient for replacing the water used for refrigeration.

[0040] As Figure 1 - Figure 2 shown, positioning grooves 22 are formed on both sides of the movable mounting plate 2, and positioning posts 12 with dimensions corresponding to the positioning grooves 22 are fixedly arranged on both sides of the opening of the heat preservation box 1. Through the above structural form, when the movable mounting plate 2 is lapped on the heat preservation box 1 and the positioning grooves 22 and the positioning posts 12 are engaged with each other, the position of the movable mounting plate 2 can be fixed, and thus the position of the reagent tube storage tube 3 can be indirectly fixed.

[0041] As Figure 1 shown, plug bolts 41 are fixedly connected to both sides of the lower end surface of the box cover 4, through holes through which the plug bolts 41 can pass are formed on both sides of the heat preservation box 1, and locking wheels 42 are threadedly connected to the plug bolts 41. Through the above structural form, when the box cover 4 is covered on the heat preservation box 1, the locking wheels 42 are tightened to realize the fixed connection between the two.

[0042] The working principle and working process of the present utility model:

[0043] An ice-water mixture or a cold source medium with a lower temperature is placed in the heat preservation box 1, which can quickly reduce the temperature of the reagent tube storage tube 3 through heat exchange. When the reagent tube is placed in the reagent tube storage tube 3, the two will be in close contact, thereby reducing the temperature of the reagent in the reagent tube and extending its effective time. And in the above process, the cold source medium does not directly contact the reagent tube and will not wet the reagent tube to cause damage to the label on it.

[0044] In addition, the reagent tube storage tube 3 of the corresponding model can be selected according to the model of the reagent tube and installed on the movable mounting plate 2, so that the overall structure has certain applicability. In particular, a plurality of heat exchange fins 34 are arranged on the surface of the heat exchange tube 31, which can further improve the heat exchange efficiency and ensure the refrigeration effect.

[0045] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
