[0002] Tumor is a genetic disease, a space-occupying protrusion formed by the proliferation of local tissue cells under the influence of tumorigenic factors. Tumors are not controlled by the body's regulatory mechanism and can spread to other parts of the body, causing harm to the human body. Therefore, after discovering a tumor, medical workers in the oncology department will sample and test the tumor. Due to the threat of tumor cells themselves, tumor cell samples need to be inactivated by heat in the dark before testing. After inactivation, they need to be placed in liquid nitrogen for low-temperature storage.

[0003] In the prior art, in order to prevent cross infection, the test tube containing the tumor tissue is usually thrown into warm water for high-temperature sterilization in a water bath. However, since the gas pressure in the test tube increases during heating, and the lid of the sealed test tube cannot be opened when thrown into the water, the high-pressure gas cannot be discharged, and it is inconvenient to take out the test tube later. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and to propose a sample storage device for oncology testing, which can keep the lid in a non-sealed state during heating, so that the air pressure inside and outside the test tube is consistent, avoiding excessive pressure in the test tube; and after inactivation is completed, the lid can be automatically closed and the test tube can be automatically taken out of water.

[0024] The mounting unit 1 comprises a shell 101, a mounting cover 102 arranged on the shell 101 and having a feed port 1021 and a discharge port 1022, a turntable frame 103 rotatably arranged in the mounting cover 102 and having a plurality of fixing holes, and a driving motor 104 arranged on the mounting cover 102 and having an output end connected to the turntable frame 103; the heating unit 2 is arranged in the shell 101; the discharge unit 3 is arranged on the mounting cover 102 and is located at the discharge port 1022; a plurality of storage units 4 are arranged and embedded in the fixing holes; a clamping mechanism is slidably arranged on the discharge unit 3 and is clamped with the storage unit 4.

[0025] Furthermore, the heating unit 2 includes an elastic member 203 arranged in the shell 101, a heating plate 202 arranged on the elastic member 203, and a heating barrel 201 arranged on the heating plate 202 and detachably connected; the heating barrel 201 is abutted against the top of the shell 101; water is poured into the heating barrel 201, and then the heating barrel 201 is inserted into the shell 101, and the heating plate 202 is pushed upward by the elastic member 203, so that the heating plate 202 is firmly connected to the heating barrel 201 and the heating barrel 201 can be moved upward, and a light shield is provided at the position where the heating barrel 201 is installed in the shell 101, and then the light shield is covered after the heating barrel 201 is inserted into the shell 101; the water in the heating barrel 201 is heated by the heating plate 202, so that the water in the heating barrel 201 can kill the tumor tissue in the storage unit 4 at high temperature, and the killing operation is performed by a water bath method.

[0026] Furthermore, the discharge unit 3 includes a support frame 301 arranged on the mounting cover 102 and located at the discharge port 1022, and a discharge slide rail 302 arranged on the support frame 301 and having a U-shaped structure and an opening expanding outward; the discharge slide rail 302 can be supported by the support frame 301, and the discharge slide rail 302 can support the storage unit 4, so that the storage unit 4 can be easily removed.

[0027] Furthermore, the storage unit 4 includes a storage tube 401 having an outer diameter smaller than the fixing hole and embedded in the turntable frame 103, a pipe mouth platform 402 having an outer diameter larger than the fixing hole and arranged on the storage tube 401 and capable of abutting against the turntable frame 103, and a sealing cover 403 arranged on the pipe mouth platform 402 and threadedly sealed.

[0028] In this embodiment, the extracted tumor tissue is placed in the storage tube 401, and the protective solution is injected, and then the sealing cover 403 is covered on the tube mouth platform 402. At this time, there is no need to tighten the sealing cover 403. The storage tube 401 is inserted into the fixing hole on the turntable frame 103 through the feed port 1021, so that the storage tube 401 is located in the heating barrel 201 and can be heated and killed in a water bath. The tube mouth platform 402 is placed on the turntable frame 103 to prevent the storage tube 401 from falling into the heating barrel 201, and a relatively sealed and light-proof space is formed between the turntable frame 103 and the heating barrel 201. The fixing hole is blocked by the sealing cover 403, so that the water bath inactivation treatment can be better performed, and the air pressure in the storage tube 401 is prevented from increasing during heating. Therefore, the sealing cover 403 is in an untightened state at this time, so that the air pressure can escape from the gap between the sealing cover 403 and the tube mouth platform 402.

[0029] The turntable frame 103 is driven to rotate by the driving motor 104, and the turntable frame 103 drives the storage unit 4 to rotate the position of the fixed hole, so that the storage unit 4 can move to the inside of the installation cover 102, and the storage unit 4 that has been sterilized in the water bath is moved to the bottom of the clamping mechanism, and the clamping unit 5 is driven to move downward by the moving mechanism 8, and the clamping unit 5 drives the spinning unit 7 to move downward, so that the spinning unit 7 first contacts the sealing cover 403, thereby causing the spinning unit 7 to rotate, and when the spinning unit 7 rotates, the sealing cover 403 is driven to rotate by the friction force, and the sealing cover 403 is threadedly connected to the nozzle platform 402, so that the sealing cover 403 completely seals the nozzle platform 402 and the storage tube 401, and at this time the clamping unit 5 is stuck on the sealing cover 403, and the clamping unit 5 is driven to move upward by the moving mechanism 8, so that the clamping unit 5 drives the storage unit 4 to move upward, so that the storage unit 4 can move to the unloading slide rail 302, and at this time the sealing cover 403 is located above the unloading slide 302, and the clamping unit 5 is pushed to move horizontally by the moving mechanism 8, thereby driving the storage unit 4 to move toward the direction of the unloading slide 302, so that the storage tube 401 is located between the unloading slides 302, and the opening of the unloading slide 302 expands outward so that it can be directly connected to the inner wall of the support frame 301, and can guide the storage tube 401, so that the storage tube 401 is pushed onto the unloading slide 302, so that the unloading slide 302 can support the storage tube 401, and the clamping unit 5 is driven by the moving unit 6 to release the storage unit 4, and the storage unit 4 is pushed downward by the spinning unit 7, so that the storage unit 4 falls onto the unloading slide 302, and the moving mechanism 8 drives the clamping unit 5 to retract, waiting for the next storage unit 4 to be sterilized in a water bath, and the staff removes the sterilized storage unit 4 from the unloading slide 302 and puts it into a liquid nitrogen box for low-temperature storage.

[0030] The present invention can automatically perform high-temperature sterilization of tumor tissue in a water bath in a light-proof environment, and after the sterilization is completed, the storage unit 4 can be automatically taken out from the heating barrel 201 and moved to the unloading slide rail 302 for medical staff to take. During the sterilization, only part of the storage tube 401 is located in the water, and the sealing cover 403 is not completely in sealing contact with the storage tube 401. Therefore, heat transfer can be reduced and the sealing cover 403 can be prevented from being affected by high temperature. After the storage unit 4 is taken out, it is placed in a liquid nitrogen box for low-temperature storage.

[0031] Embodiment 2 like Figure 1-8 As shown, a sample storage device for oncology detection proposed by the present invention, compared with the first embodiment, the clamping mechanism in this embodiment includes a clamping unit 5 slidably arranged in the support frame 301 and engaged with the sealing cover 403, a moving unit 6 arranged on the clamping unit 5, a spinning unit 7 arranged on the clamping unit 5 and abutting against the sealing cover 403, and a moving mechanism 8 arranged on the support frame 301 for driving the clamping unit 5 to move.

[0032] Furthermore, the clamping unit 5 includes a mounting frame 503 arranged on the moving mechanism 8, two sliding plates 502 slidably arranged on the mounting frame 503, two arc-shaped clamping claws 501 respectively arranged on the two sliding plates 502, and a mounting plate 504 arranged on the clamping claws 501; the output end of the moving unit 6 is connected to the sliding plate 502.

[0033] Further, the mobile unit 6 includes a guide rail 601 arranged on the clamping jaw 501, two push plates 602 slidably arranged on the guide rail 601 and capable of abutting against the sliding plate 502, two connecting rods 603 rotatably arranged on the push plates 602, a pressing assembly 605 arranged on the mounting plate 504 and having an output end connected to the connecting rods 603, and an elastic member 604 arranged on the guide rail 601 and having two ends respectively connected to the sliding plate 502 and the mounting frame 503; the pressing assembly 605 includes a connecting block and a telescopic cylinder rotatable with the connecting rod 603, and the pressing assembly 605 is controlled by the telescopic cylinder. The position of the connecting block is controlled, and the connecting block drives the connecting rod 603 to move, and the connecting rod 603 drives the push plate 602 to move, so that the push plate 602 adjusts the movable range of the sliding plate 502, and can avoid the distance between the two clamping jaws 501 being much smaller than the diameter of the sealing cover 403, and the lower end of the clamping jaw 501 is provided with an inclined surface, so that when the clamping jaw 501 moves downward, the inclined surface guides the clamping jaw 501 to automatically expand outward until the sealing cover 403 is completely clamped, and then the sliding plate 502 is pushed to move by the elastic member 2 604, driving the clamping jaw 501 to clamp the sealing cover 403, thereby fixing the storage unit 4 and being able to lift the storage unit 4.

[0034] In this embodiment, when it is necessary to take out the storage unit 4 that has been sterilized at high temperature, the mounting frame 503 is driven to move downward by the moving mechanism 8, and the mounting frame 503 drives the sliding plate 502 to move downward, and the sliding plate 502 drives the clamping jaw 501 to move downward, so that the clamping jaw 501 moves to the sealing cover 403. When it continues to move downward, the clamping jaw 501 will be squeezed so that the clamping jaw 501 separates to both sides, and the elastic member 2 604 pushes the sliding plate 502 to close. The clamping jaw 501 is a stepped structure, so after it can move to the lower end of the sealing cover 403 at the step, the sliding plate 502 is pushed to move by the elastic member 2 604, and the sliding plate 502 drives the clamping jaw 501 to move and get stuck on the sealing cover 403, so that the clamping jaw 501 can be clamped with the sealing cover 403.

[0035] After the clamping is completed, the mounting frame 503 is driven to move upward by the moving mechanism 8, driving the sliding plate 502 and the clamping claw 501 to move upward, so that the storage unit 4 is pulled out from the discharge port 1022 and moved to the top of the unloading slide rail 302. The clamping unit 5 is extended by the moving mechanism 8, so that the storage unit 4 is moved to the unloading slide rail 302. The unloading slide rail 302 is clamped on the storage tube 401, and the tube mouth platform 402 is located above the unloading slide rail 302, so that the storage unit 4 can be supported. The connecting rod 603 is driven to move downward by the pressing component 605, so that the connecting rod 603 pushes the push plate 602 to move, and the push plate 602 pushes the sliding plate 502 to expand outward, so that the mounting frame 503 is separated from the sealing cover 403, and then the sealing cover 403 is pushed downward by the spinning unit 7, so that the storage unit 4 can be separated from the clamping unit 5, so that the storage unit 4 can completely fall onto the unloading slide rail 302, and then the storage unit 4 is removed from the unloading slide rail 302 and placed in the liquid nitrogen box for storage.

[0036] Embodiment 3 like Figure 1-8 As shown, a sample storage device for oncology detection proposed by the present invention, compared with embodiment one or embodiment two, the spinning unit 7 in this embodiment includes a nut sleeve 703 arranged on the mounting frame 503, a threaded rod 702 threadedly connected to the nut sleeve 703, a pressure plate 701 arranged at the lower end of the threaded rod 702 and abutting against the sealing cover 403, and an elastic member 704 arranged at both ends of the outer peripheral side of the threaded rod 702 and connected to the mounting frame 503 and the pressure plate 701 respectively.

[0037] Furthermore, the nut sleeve 703 includes a sleeve body 7031 with a threaded groove inside, a plurality of ball bearings 7032 that are slidably arranged in the sleeve body 7031 and slidably connected to the threaded rod 702, and a flange 7033 that is arranged at the end of the sleeve body 7031 and on the mounting frame 503; the sleeve body 7031 is installed on the mounting frame 503 through bolts on the flange 7033, and the threaded rod 702 is threadedly connected to the sleeve body 7031. The friction between the threaded rod 702 and the sleeve body 7031 is reduced by the ball bearings 7032, so that the threaded rod 702 can rotate more smoothly, which makes it convenient for the threaded rod 702 to drive the pressure plate 701 to rotate. A limiting nut is arranged at the upper end of the threaded rod 702 to prevent the threaded rod 702 from falling off the sleeve body 7031.

[0038] In this embodiment, after the storage unit 4 is sterilized at high temperature, the clamping unit 5 is driven to move downward by the moving mechanism 8, so that the mounting frame 503 drives the spinning unit 7 to move downward, and the elastic member three 704 pushes the pressure plate 701 to move downward, so that the pressure plate 701 drives the threaded rod 702 to move downward. When the pressure plate 701 contacts the sealing cover 403, the clamping unit 5 continues to move downward, so that the threaded rod 702 moves upward relatively. The threaded rod 702 is threadedly connected with the nut sleeve 703, so that the threaded rod 702 rotates and moves upward. The pressure plate 701 is driven by the threaded rod 702 and the pressure given by the elastic member three 704 to increase the friction with the sealing cover 403, thereby driving the sealing cover 403 to rotate when the pressure plate 701 rotates, and tightening the sealing cover 403 until the clamping unit 5 clamps the sealing cover 403.

[0039] When the storage unit 4 needs to be removed from the clamping unit 5, the clamping unit 5 releases the limit on the sealing cover 403. In order to prevent the storage unit 4 from being stuck on the clamping unit 5, the thrust generated by the pressure plate 701 pushes the storage unit 4 downward, so that the storage unit 4 falls onto the unloading slide rail 302, so that the storage unit 4 can be removed and then placed in the liquid nitrogen box for storage.

[0040] Embodiment 4 like Figure 1-8 As shown, a sample storage device for oncology detection proposed by the present invention, compared with embodiment one or embodiment two or embodiment three, the moving mechanism 8 in this embodiment includes a lifting component 801 arranged on the support frame 301, a support arm 802 connected to the output end of the lifting component 801, and a moving component 803 arranged on the support arm 802 and whose output end is connected to the mounting frame 503.

[0041] In this embodiment, the lifting component 801 is a screw lifting structure, which can drive the support arm 802 to move in the vertical direction through the lifting component 801, thereby driving the clamping unit 5 to move, contact the storage unit 4, and pull the storage unit 4 out of the discharge port 1022. The moving component 803 is a telescopic cylinder structure, which can drive the clamping unit 5 to move horizontally and push the pulled-out storage unit 4 to the unloading slide rail 302, thereby facilitating the unloading operation.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
