Description

Technical Field

[0001] This utility model relates to the field of cell sample storage, and in particular to a sample storage device for tumor cell detection. Background Technology

[0002] Tumor cell detection is a core component of clinical diagnosis and treatment evaluation. By accurately identifying the presence, type, quantity, and biological characteristics of tumor cells in a sample, it provides an objective basis for tumor-related medical decisions.

[0003] Existing storage devices lack independent isolation design for sample chambers, making them prone to cross-contamination and affecting the accuracy of test results. Since tumor cell samples need to be heated and inactivated before testing, it is necessary to wait for the samples to cool down before testing in order to improve the accuracy of sample test data. Natural cooling is slow, so a sample storage device that can rapidly cool tumor cell samples is needed. Utility Model Content

[0004] In view of this, the present invention provides a sample storage device for tumor cell detection. The main technical problem to be solved is: to provide a sample storage device for tumor cell detection that can store samples separately and can rapidly cool the samples.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sample storage device for tumor cell detection, comprising an outer shell, an inner liner installed inside the outer shell, a plurality of mounting grooves being formed on the inner wall of the inner liner, mounting posts being installed inside each of the plurality of mounting grooves, an elastic strip being fixedly connected to the surface of the mounting post, a limiting ring being fixedly connected to the end of the elastic strip away from the mounting post, the limiting ring being located inside the inner liner, a plurality of connecting holes being formed inside the inner liner, the connecting holes being located between two mounting grooves, a through hole being formed at the bottom of the outer shell, a fan being fixedly connected to the inner bottom of the outer shell, the fan being located below the inner liner, and a top cover being installed on the top of the outer shell.

[0006] By adopting the above technical solution, when in use, the test tube containing the sample for testing is placed into the inner liner. When the test tube is placed into the inner liner, it will push the elastic strip outward. After the test tube is placed into the inner liner, the elastic strip will rebound and cooperate with the limiting ring to clamp and fix the test tube. When it is necessary to cool the test tube, the fan at the bottom of the outer shell is turned on. The fan works to draw in outside air. The air passes through the through hole and the connecting hole in sequence and enters the inner liner, accelerating the air flow inside the outer shell and carrying away the heat inside the outer shell, thereby rapidly cooling the test tube and the sample inside the test tube.

[0007] As a further description of the above technical solution:

[0008] A cavity is formed between the outer shell and the inner liner, and the connecting hole is connected to the cavity.

[0009] By adopting the above technical solution, air first enters the cavity from the outside, and then enters the inner liner through the connecting hole.

[0010] As a further description of the above technical solution:

[0011] The side wall of the mounting groove is provided with a limiting groove, and the side of the mounting column is fixedly connected with a limiting strip, which is located inside the limiting groove.

[0012] By adopting the above technical solution, the mounting column can be stably installed in the mounting groove.

[0013] As a further description of the above technical solution:

[0014] The top of the cover has an exhaust port, and a sealing plug is installed inside the exhaust port.

[0015] By adopting the above technical solution, when in use, the sealing plug is removed, and the air that has entered the inner liner will be discharged from the exhaust port, which facilitates the cooling of the sample in the test tube.

[0016] As a further description of the above technical solution:

[0017] A power source is fixedly connected to the inner bottom of the housing, and a wire is provided between the power source and the fan.

[0018] By adopting the above technical solution, the fan is powered by a power supply, and a switch for controlling the on and off of the circuit is also installed between the power supply and the fan.

[0019] As a further description of the above technical solution:

[0020] The bottom of the outer casing is fixedly connected to a set of feet, and there are multiple sets of feet with gaps between them.

[0021] By adopting the above technical solution, the outer casing can be raised by the foot, making it easier for outside air to enter the interior of the outer casing through the through hole.

[0022] By employing the above technical solution, the sample storage device for tumor cell detection of this utility model has at least the following beneficial effects:

[0023] 1. Compared with existing technologies, this sample storage device for tumor cell detection, through the combined design of elastic strips and limiting rings, achieves stable clamping and independent storage of test tubes, effectively avoiding cross-contamination between samples and ensuring the accuracy of test results. Simultaneously, the fan operation can quickly remove heat from the samples inside the test tubes, shortening cooling time and improving detection efficiency. Attached Figure Description

[0032] Reference Figure 1-6This utility model provides a sample storage device for tumor cell detection, comprising: an outer shell 1, an inner liner 2 installed inside the outer shell 1, multiple mounting grooves 3 on the inner wall of the inner liner 2, mounting posts 5 installed inside each mounting groove 3, elastic strips 7 fixedly connected to the surface of the mounting posts 5, the elastic strips 7 being made of elastic plastic or elastic metal, a limiting ring 8 fixedly connected to the end of the elastic strip 7 away from the mounting post 5, the limiting rings 8 being located inside the inner liner 2, clamping and fixing test tubes containing samples through the multiple limiting rings 8, multiple connecting holes 9 being located inside the inner liner 2, the connecting holes 9 being located between two mounting grooves 3, a through hole 13 being opened at the bottom of the outer shell 1, a fan 15 fixedly connected to the inner bottom of the outer shell 1, the fan 15 being located below the inner liner 2, and a top cover 10 installed at the top of the outer shell 1, the top of the top cover 10 having a drain... The air vent 11 has a sealing plug 12 installed inside. When in use, the sealing plug 12 is removed, and the air entering the inner liner 2 will be discharged from the air vent 11, which facilitates the cooling of the sample in the test tube. When in use, the test tube containing the sample for testing is placed into the inner liner 2. When the test tube is placed into the inner liner 2, it will push the elastic strip 7 outward. After the test tube is placed into the inner liner 2, the elastic strip 7 will rebound and cooperate with the limiting ring 8 to clamp and fix the test tube. When it is necessary to cool the test tube, the fan 15 at the bottom of the outer shell 1 is turned on. The fan 15 draws in the outside air. The air passes through the through hole 13 and the connecting hole 9 in sequence and enters the inner liner 2, accelerating the air flow inside the outer shell 1 and carrying away the heat inside the outer shell 1, thereby rapidly cooling the test tube and the sample inside the test tube. A cavity is formed between the outer shell 1 and the inner liner 2. The connecting hole 9 is connected to the cavity. The air first enters the cavity from the outside and then enters the inner liner 2 through the connecting hole 9.

[0033] A limiting groove 4 is provided on the side wall of the mounting groove 3, and a limiting strip 6 is fixedly connected to the side of the mounting column 5. The limiting strip 6 is located inside the limiting groove 4, so that the mounting column 5 can be stably installed in the mounting groove 3.

[0034] A power supply 14 is fixedly connected to the bottom of the outer casing 1. A wire is provided between the power supply 14 and the fan 15 to supply power to the fan 15. A switch (not shown) for controlling the on and off of the circuit is also provided between the power supply 14 and the fan 15.

[0035] The bottom of the outer casing 1 is fixedly connected with a foot 16. There are multiple feet 16, and gaps are provided between the multiple feet 16. The feet 16 can raise the outer casing 1, so that outside air can pass through the through hole 13 and enter the interior of the outer casing 1.

[0036] Working Principle: When storing and cooling tumor cell test samples, the test tubes containing the samples are first placed one by one into the inner liner 2. During placement, the test tubes push the elastic strip 7 outward, causing it to deform. After the test tubes are fully placed, the elastic strip 7, with its own elastic recovery force, works in conjunction with the limiting ring 8 to firmly clamp the test tubes. The individual storage device ensures that each test tube is stored independently, effectively avoiding cross-contamination between samples. When cooling of the samples in the test tubes is required, the switch between the power supply 14 and the fan 15 is turned on, and the fan 15 starts working, drawing in outside air. The air first passes through the gap between the feet 16, through the through hole 13 into the cavity formed by the outer shell 1 and the inner liner 2, and then enters the interior of the inner liner 2 through the connecting hole 9. At this time, the sealing plug 12 in the exhaust port 11 at the top of the top cover 10 is removed, and the air entering the inner liner 2 will be discharged from the exhaust port 11, forming an air circulation channel, accelerating the airflow inside the outer shell 1, quickly removing the heat from the samples in the test tubes, and achieving rapid cooling of the samples.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
