Description

Technical Field

[0001] This utility model relates to the field of sample preservation technology, and in particular to a sample preservation device for tumors. Background Technology

[0002] In the fields of cancer research and clinical treatment, accurate analysis and diagnosis of tumor samples are crucial, and obtaining high-quality tumor samples and preserving them properly are the foundation for subsequent research and treatment.

[0003] Traditional methods for tumor sampling and preservation often involve temporary storage using ice packs or refrigerators. This not only makes it difficult to control the temperature but also to maintain the required low-temperature environment for extended periods, affecting the activity and integrity of the tumor samples and consequently the accuracy of detection and analysis results. Furthermore, the inability to monitor the temperature of the sample storage environment in real time makes it difficult to detect abnormal temperatures promptly, which can easily lead to sample damage. Therefore, we propose a tumor sampling and preservation device to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that use ice packs or refrigerators to preserve tumor samples, which result in difficulty in temperature control and short preservation time, affecting sample activity and integrity. Therefore, this invention proposes a tumor sampling and preservation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tumor sampling and preservation device includes a housing with a sealing cover hinged to its top. A control panel is fixedly mounted on one side of the housing. Two fixing posts are fixedly mounted on the inner walls of the two adjacent sides of the housing. A shelf is fixedly connected to the top of the four fixing posts. The shelf has multiple refrigeration chambers for storing sample boxes. Liquid inlets are located at the bottom of the multiple refrigeration chambers. A lithium battery is fixedly mounted on the bottom inner wall of the housing and electrically connected to the control panel. The device also includes:

[0007] The refrigeration unit is located on the bottom inner wall of the cabinet and is used to refrigerate and preserve samples in multiple refrigeration chambers.

[0008] Multiple monitoring components are installed in the corresponding refrigeration chambers to monitor the temperature inside the refrigeration chambers.

[0009] In one possible design, the refrigeration assembly includes a liquid nitrogen tank, which is fixedly mounted on the bottom inner wall of the housing. A multi-channel guide pipe is fixedly mounted on the bottom inner wall of the housing. One end of the liquid nitrogen tank has a liquid outlet, which is connected to the multi-channel guide pipe via a first connecting pipe. Multiple liquid inlets are connected to the multi-channel guide pipe via second connecting pipes. The bottom inner walls of multiple refrigeration chambers are provided with guide grooves that communicate with the liquid inlets. Electric flow valves are mounted on the first connecting pipe and the multiple second connecting pipes. The multiple electric flow valves are electrically connected to the lithium battery and the control panel.

[0010] In one possible design, a booster pump is fixedly installed on the bottom inner wall of the housing, and an air inlet pipe is fixedly connected to the other end of the liquid nitrogen tank. The air outlet of the booster pump is connected to the air inlet pipe through a third connecting pipe. A solenoid valve is installed on the third connecting pipe, and the solenoid valve is electrically connected to the lithium battery and the control panel.

[0011] In one possible design, the monitoring component includes temperature sensors fixed to the inner wall of the refrigeration chamber, and all temperature sensors are electrically connected to the lithium battery and the control panel.

[0012] In one possible design, each of the multiple refrigeration cavities is provided with a cover plate at its opening, and the inner wall of each refrigeration cavity is provided with symmetrical grooves. The cover plate is rotatably connected to one of the grooves, and two locking blocks are fixed on both sides of the cover plate. The two locking blocks are engaged with the inner walls of the other groove.

[0013] In one possible design, a sealing strip is fixedly embedded in the top of the box, heat insulation plates are provided on the four fixed posts below the placement rack, and a ventilation slot is provided on one side of the sealing cover.

[0014] In this application, firstly, the sealing cover is opened, the sample box containing the tumor sample is placed into the refrigeration chamber on the placement rack, and then the cover is closed so that the locking block and the groove are engaged, thus confining the sample box containing the tumor sample within the refrigeration chamber and providing a certain sealing effect to the refrigeration chamber.

[0015] Next, the device is started via the control panel. The lithium battery powers the entire device, starts the booster pump and opens the solenoid valve on the third connecting pipe. The booster pump pressurizes the liquid nitrogen tank through the third connecting pipe and the air inlet pipe. At the same time, the electric flow valves on the first connecting pipe and multiple second connecting pipes are opened. Under pressure, the liquid nitrogen in the liquid nitrogen tank enters the multi-channel guide pipe through the first connecting pipe, and then enters each refrigeration chamber from the liquid inlet through the second connecting pipe. The guide grooves on the inner wall of the bottom of the refrigeration chamber can make the liquid nitrogen more evenly distributed, thereby refrigerating and preserving the sample.

[0016] Temperature sensors in each refrigeration compartment monitor the temperature in real time and transmit the temperature data to the control panel. Operators can view the temperature of each refrigeration compartment on the control panel. When the temperature in a refrigeration compartment is higher than the set value, the corresponding electric flow valve can be controlled through the control panel to increase the supply of liquid nitrogen to lower the temperature; when the temperature is lower than the set value, the supply of liquid nitrogen will be reduced.

[0017] During the liquid nitrogen evaporation process, the generated gas can be discharged from the chamber through the ventilation slot on one side of the sealed cover to prevent gas accumulation. The sealing strip on the top of the chamber and the heat insulation plate on the fixed column can effectively reduce the entry of external heat and ensure the low temperature environment inside the chamber.

[0018] Beneficial effects: In this utility model, the sampling and preservation device for tumors, by setting up a refrigeration component and using liquid nitrogen as a refrigerant, distributes liquid nitrogen evenly into each refrigeration chamber through a multi-channel guide pipe and multiple second connecting pipes, thereby achieving precise refrigeration and preservation of the sample and effectively improving the preservation quality of the sample.

[0019] In this invention, the sampling and preservation device for tumors is equipped with multiple monitoring components and uses temperature sensors to monitor the temperature inside the cold storage chamber in real time, ensuring that the sample is always within a suitable preservation temperature range, thereby further improving the preservation effect of the sample.

[0020] In this utility model, the sampling and preservation device for tumors has a cover plate at the opening of the refrigeration chamber. The cover plate has a locking structure of a locking block and a groove, which can effectively seal the refrigeration chamber, reduce the entry of external heat and the evaporation of liquid nitrogen, and further improve the stability and reliability of sample preservation.

[0021] In this invention, a refrigeration component using liquid nitrogen as a refrigerant is used to evenly distribute the liquid nitrogen into each refrigeration chamber, thereby achieving precise cold storage of samples. Multiple monitoring components can monitor the temperature inside the refrigeration chamber in real time, ensuring that the samples are always within a suitable storage temperature range. The cover plate at the opening of the refrigeration chamber can effectively seal the refrigeration chamber, reducing the entry of external heat and the evaporation of liquid nitrogen, further improving the stability and reliability of sample preservation.
