Description

Technical Field

[0001] The present invention relates to the technical field of tissue preservation, and in particular to a device for preserving tissue for extrathoracic sampling. Background Art

[0002] Extrathoracic tissue sampling and preservation refers to the proper processing and storage of pathological tissue samples obtained from outside the chest cavity to maintain the integrity of its tissue structure and genetic materials such as cellular DNA and RNA, and to provide reliable samples for subsequent diagnosis and research. Different tissues need to choose appropriate preservation conditions according to different test items and requirements. Standardized extrathoracic tissue sampling and preservation procedures can reduce the risk of sample contamination and damage.

[0003] In view of the preservation of sampled tissues, a Chinese invention patent with patent number CN117730850B discloses a low-temperature storage box for pathological sampling, which relates to the field of tissue preservation technology, including a box body, a closing plate rotatably connected to the box body, a refrigerator fixedly connected to the box body, and a partition plate fixedly connected to the box body. A plurality of partition boxes equidistantly distributed are fixedly connected between the partition plate and the box body, each partition box is connected to a left-right symmetrical docking pipe, the docking pipe passes through the partition plate, the partition box is slidably connected to a storage box, the docking pipe extends into an adjacent storage box, the samples are stored independently in the storage boxes, and cold air is transported into the storage box through the docking pipe to store the samples at a low temperature. When taking the samples, only one of the storage boxes needs to be pulled forward, which will not affect the storage effect of other samples.

[0004] Although the above scheme improves the storage effect to a certain extent when preserving sampled tissues, in actual use, since the sealing method of the butt tube is relatively simple, the sealing components may be mechanically worn due to long-term use or improper operation, which may reduce the sealing performance of the storage box and further affect its thermal insulation effect.

Each group of docking pipes 300 includes two docking pipes 300 arranged on the left and right, connecting the refrigerator 120 and the storage box 110, and is used to transport the cold air generated by the refrigerator 120 to the storage box 110; The docking covers 140 are provided in multiple groups and correspond to the docking pipes 300 one by one. Each group of docking covers 140 includes two docking covers 140 arranged on the left and right, fixed to the rear of the inner wall of the storage box 110 and communicated with the docking pipe 300, for receiving cold air; The air supply pipes 150 are provided in multiple groups and correspond to the docking covers 140 one by one. Each group of air supply pipes 150 includes two air supply pipes 150 arranged on the left and right sides, which are respectively fixed to the left and right side walls of the storage box 110 and communicated with the corresponding docking pipes 300, and are used to transport and disperse cold air. The closing components 200 are provided in multiple groups and correspond one to one with the storage boxes 110, and are respectively fixed on the partition plates 130 and correspond to the positions of the storage boxes 110. The closing components 200 are provided with horizontally arranged blocking blocks 221, and the blocking blocks 221 are on the same horizontal line as the docking tubes 300, and are used to seal the docking tubes 300 by magnetic attraction to prevent cold air leakage.

[0033] The sealing assembly 200 includes a telescopic rod 210, a connecting plate 220, a blocking block 221, an electromagnet 1 230 and an electromagnet 2 231; The telescopic rod 210 is fixed to the rear side of the partition plate 130 and is used to support the connecting plate 220; The connecting plate 220 is fixed to the telescopic end of the telescopic rod 210 and is used to drive the blocking block 221 to achieve synchronous movement; The blocking blocks 221 are provided with two, corresponding to the butt joint pipes 300 one by one, fixed on the connecting plate 220, and used to block the butt joint pipes 300; The electromagnet 1 230 is provided with two, arranged on the left and right, and fixed on the partition plate 130; The electromagnets 231 are provided with two, corresponding to the positions of the electromagnets 1 230 one by one, fixed on the connecting plate 220, and used for cooperating with the electromagnets 1 230 to drive the blocking block 221 to move and seal the butt joint 300.

[0034] The blocking block 221 is a cone structure and an airbag 222 is fixed on the outside thereof. The airbag 222 is a cone-shaped ring structure and is used to control the sealing degree by controlling the expansion amount of the airbag 222 .

[0035] The refrigerator 120 is used to cool the sample storage box 100 and deliver cold air, and is preferably a compression refrigerator, which is a prior art and will not be described in detail here.

[0036] When the embodiment of the present application is actually running, the steps are as follows: Step 1: In the initial state, the refrigerator 120 is started, and the cold air enters the storage box 110 through the docking pipe 300; Step 2: When the sample needs to be stored, the staff rotates the closing plate 101 forward to open it, and then pulls the storage box 110 to slide forward in the box body 100 and extend it out. After the storage box 110 slides forward, it is separated from the docking tube 300; Step 3: Start the electromagnet 1 230 to generate magnetic force, attract the electromagnet 2 231 on the connecting plate 220 and drive the blocking block 221 to move toward the butt joint pipe 300, so that the blocking block 221 is close to the input end of the butt joint pipe 300; Step 4: Fill the airbag 222 with a proper amount of gas. After the airbag 222 is inflated, it expands and tightly squeezes the butt joint 300 to further enhance the sealing effect. Step 5: After the staff puts the sample into the storage box 110 and pushes the storage box 110 to slide into the box body 100, a proper amount of gas is extracted into the airbag 222. After the airbag 222 is deflated, it shrinks and is not in close contact with the input end of the docking tube 300. The electromagnet 1 230 is started to generate an opposite magnetic force, which repels the electromagnet 2 231 on the connecting plate 220 and drives the blocking block 221 to move away from the docking tube 300, so that the blocking block 221 is separated from the input end of the docking tube 300, thereby realizing the entry of cold air.

[0037] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: Through the magnetic sealing method, the electromagnet 1 230 attracts the connecting plate 220 and the electromagnet 2 231 and drives the blocking block 221 to move, so that the blocking block 221 can contact and seal the pipe mouth of the docking pipe 300, thereby avoiding the problem of poor sealing due to mechanical friction or wear. The conical blocking block 221 and the conical docking joint 310 are arranged to increase the contact area and improve the sealing effect; the airbag 222 is arranged and the sealing degree is fine-tuned by controlling its expansion amount to ensure that the best sealing effect can be achieved under different conditions, thereby solving the technical problems in the prior art that the sealing performance is reduced, the thermal insulation effect is reduced and the scope of application is limited due to mechanical wear, and the technical effect of avoiding the reduction of sealing performance due to mechanical wear, stabilizing the thermal insulation effect and expanding the scope of application is achieved.

[0038] Embodiment 2: In order to improve the stability of cold air when entering and enhance the refrigeration effect, the present application proposes the following technical solutions for the above technical problems, specifically: like Figure 6 and Figure 7 As shown, the butt joint pipe 300 has three sections, namely a butt joint 310, a telescopic pipe 320 and a fixed pipe 330; The docking joint 310 is a conical opening, which is arranged at the front end of the telescopic tube 320 and cooperates with the blocking block 221 to have a guiding function; the telescopic tube 320 is a flexible structure and is made of low-temperature resistant silicone material. It is arranged in the middle of the telescopic tube 320 and has multiple vertically placed position plates 341 fixed inside it to change the flow path of cold air; the fixed tube 330 is a rigid structure, which is fixed on the partition plate 130 and passes through the partition plate 130 and is connected to the inside of the storage box 110.

[0039] The present application divides the docking tube 300 into three parts and provides a flexible and retractable telescopic tube 320 to increase the contact time and area between the cold air and the inner wall of the docking tube 300 and the internal air. This helps the cold air to more fully cool the docking tube 300 and the air inside it, thereby improving the heat exchange efficiency. In addition, the provision of multiple position plates 341 can extend the cold air movement path, thereby helping to reduce the energy loss of the cold air during the flow process and enhancing the overall cooling effect.

[0040] By arranging the position plates 341 in a staggered arrangement, the cold air is forced to change its flow direction when passing through the butt joint tube 300, forming a more complex flow field. This not only helps the cold air to be more evenly distributed in the butt joint tube 300, reduces the temperature gradient, and improves the temperature uniformity, but also helps to maintain a quiet and stable working environment and improve the quality of sample preservation. At the same time, when the telescopic tube 320 is extended or retracted or subjected to external force, the position plates 341 can disperse the stress and reduce the risk of pipeline deformation and damage, thereby enhancing the overall structural stability of the butt joint tube 300.

[0041] Embodiment 3: Considering that biopsy samples usually contain living human tissues, and these tissues need to pay special attention to temperature conditions during storage to avoid denaturation, necrosis, etc., and biopsy samples for different sample tests require different storage temperatures. In order to ensure the accuracy of the test results, this application proposes the following technical solutions for the above technical problems, specifically: like Figures 7 to 9 As shown, an adjustment component 340 is fixed inside the telescopic tube 320 , and the adjustment component 340 is used to adjust the amount of cold air entering, thereby fine-tuning the internal temperature of the storage box 110 .

[0042] A moving groove 321 is provided at the folding portion of two upper and lower adjacent telescopic tubes 320 , and the vertical cross-section of the moving groove 321 is a trapezoidal structure.

[0043] The adjustment assembly 340 includes a position plate 341 and an electromagnetic slider 342; The position plates 341 are provided in plurality, arranged in an up-and-down staggered manner and respectively fixed at the folded positions of the corresponding positions of the telescopic tube 320; There are multiple electromagnetic sliders 342, which correspond one to one with the position plates 341, and are respectively slidably connected in the corresponding movable grooves 321 and connected to the corresponding position plates 341 by a hinged manner. They are used to move along the movable grooves 321 and drive the position plates 341 to deflect at an angle under the magnetic force of the electromagnet 231, thereby controlling the flow and velocity of the cold air.

[0044] The lateral distance of the movable groove 321 located below is 1.5 times the lateral distance of the movable groove 321 located above; the rotation tilt angle range of the position plate 341 located below is 0-40°, and the rotation tilt angle range of the position plate 341 located above is 0-30°.

[0045] The present application can control the displacement of the block 221 by adjusting the magnetic force of the electromagnet 1 230, thereby accurately controlling the extension and retraction of the telescopic tube 320. At the same time, the cooperation between the electromagnetic slider 342 and the electromagnet 2 231 enables the position plate 341 to tilt to different degrees, thereby changing the path and flow rate of the cold air through the telescopic tube 320. This adjustment mechanism allows the temperature in the storage box 110 to be accurately controlled within the required range, meeting the different temperature requirements of different biopsy samples.

[0046] At the same time, since the storage temperatures required for different biopsy samples may be different, by adjusting the spacing and inclination of the position plate 341, the amount and speed of cold air introduced can be flexibly changed to achieve fine-tuning of the storage sample temperature. By fine-tuning the storage temperature, the temperature requirements of the biopsy samples can be more accurately met, the sample quality can be maintained, and the accuracy of the test results can be ensured; it can also enable the device to be flexibly adjusted according to different testing needs, adapt to a variety of different testing needs, reduce sample loss and the cost of repeated testing due to improper temperature control, and improve the flexibility and versatility of the system.

[0047] Embodiment 4: In order to further achieve accurate control of the internal temperature of the storage box 110 to improve the sample preservation quality and the preservation effect of the storage box 110, the present application proposes the following technical solutions for the above technical problems, specifically: like Figures 7 to 11 As shown, an adjustment knob 170 is fixed on the outside of the storage box 110, and the adjustment knob 170 has a built-in current regulator for adjusting the magnetic force of the electromagnet 230 and controlling the displacement of the block 221, the extension and contraction of the telescopic tube 320, the distance between two adjacent position plates 341 and the inclination of the position plates 341, thereby controlling the refrigeration temperature inside the storage box 110.

[0048] A temperature sensor 180 is fixed to the rear side of the storage box 110 . The temperature sensor 180 cooperates with the adjustment knob 170 to monitor the internal temperature of the storage box 110 in real time and provide feedback to the temperature adjustment knob 170 .

[0049] The current regulator is used to adjust the magnetic force of the electromagnet 230, and is preferably a digital current regulator; the temperature sensor 180 is used to monitor the internal temperature of the storage box 110, and is preferably a resistance temperature detector; both are prior arts and will not be described in detail here.

[0050] In actual use, this embodiment takes the following three states as examples: (1) State 1 (rotate the knob two small grids clockwise) If the initial temperature is -40°C, the wind force of the cold wind entering the docking tube 300 is 1.0 m / s, the temperature adjustment knob 170 rotates two small grids clockwise, the magnetic force between the electromagnet 1 230 and the electromagnet 2 231 increases by 20% to 1.2XN; the telescopic tube 320 shrinks by 20mm; the block 221 moves by 20mm (2 grids x 10mm / grid), that is, the distance between the two adjacent position plates 341 decreases by 4mm, the position plates 341 on the upper and lower sides are both tilted by 4° (10mm shrinkage / 2mm / ° tilt ratio), and the upper and lower electromagnetic sliders 342 are both moved horizontally by 4mm (10mm shrinkage / 2mm movement tilt ratio), at this time the wind force drops to 0.8m / s (2 grids x 0.1m / s), and the temperature begins to rise to -39.6°C.

[0051] (2) State 2 (the knob continues to be turned clockwise to fine-tune by half a grid) On the basis of state 1, the temperature adjustment knob 170 continues to fine-tune clockwise by one-half grid, the magnetic force between the electromagnet 1 230 and the electromagnet 2 231 increases by another 5% to 1.26XN, the telescopic tube 320 contracts by another 5mm, a total contraction of 25mm, the block 221 moves by another 5mm, a total displacement of 25mm, the lower position plate 341 tilts an additional 1°, a total tilt of 5°, the upper position plate 341 remains unchanged, the lower electromagnetic slider 342 moves an additional 0.5mm laterally, a total movement of 4.5mm; the upper electromagnetic slider 342 remains stationary, the wind speed drops to 0.75m / s, the temperature continues to rise and approaches -39.5°C.

[0052] (3) State 3 (temperature control system stable temperature) The temperature sensor 180 detects that the internal temperature of the storage box 110 is close to -39.5°C. The temperature control system stabilizes the temperature by fine-tuning the temperature adjustment knob 170. Parameters such as the magnetic force between the electromagnet 1 230 and the electromagnet 2 231, the extension amount of the telescopic tube 320, the inclination and distance of the position plate 341, and the position of the electromagnetic slider 342 may be slightly adjusted to maintain temperature stability and control temperature fluctuations within an acceptable range to ensure the quality of sample preservation.

[0053] The present application forms a stable control system through the coordinated use of the electromagnetic slider 342 and the electromagnet 1 230 and the electromagnet 2 231. The coordinated use of the adjustment knob 170 and the temperature sensor 180 can accurately control the magnetic force of the electromagnet 1 230, and achieve fine adjustment of the extension amount of the telescopic tube 320 and the inclination degree of the position plate 341, making the temperature control more accurate, thereby achieving accurate regulation of the temperature in the storage box 110, meeting the strict temperature requirements of different pathological samples, and improving the stability and reliability of the system.

[0054] Setting the temperature adjustment knob 170 provides the user with an intuitive operating interface, allowing the user to easily adjust the temperature inside the storage box 110 according to needs, and by setting the temperature sensor 180, the temperature inside the box can be monitored in real time, and the data can be fed back to the temperature adjustment knob 170 or a control system connected thereto, so that the user can correct the temperature deviation by adjusting the temperature adjustment knob 170 according to the feedback from the temperature sensor 180, ensuring that the temperature inside the storage box 110 is always maintained within the set range to meet the dynamic needs of sample preservation, thereby improving flexibility of use, reducing energy consumption and costs, and improving user experience and sample preservation quality.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
