[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A specimen storage device for reducing contamination includes a refrigeration chamber 1, a baffle 2, a partition 4, a circulating transfer mechanism 5, a base plate 6, and test tubes 7. The top of the refrigeration chamber 1 has an opening on one side, and the top middle of the refrigeration chamber 1 is hinged to one end of the baffle 2, which can cover the top opening of the refrigeration chamber 1. A pull rod 3 is fixedly installed on the top of the other end of the baffle 2. The baffle 2 is provided with a transparent observation window for medical personnel to observe the transfer of test tubes 7 inside the refrigeration chamber 1.

[0033] A base plate 6 is fixedly connected to the bottom of the refrigeration chamber 1; two partitions 4 are symmetrically fixedly installed on the front and rear side walls inside the refrigeration chamber 1, dividing the interior of the refrigeration chamber 1 into a placement chamber 11 and a cold storage chamber 12, and a through groove is opened between the two partitions 4 to connect the two chambers; wherein, the placement chamber 11 is used to store test tubes 7 containing tumor specimens, and the cold storage chamber 12 is used to ensure the quality and integrity of the tumor specimens in the test tubes 7; a baffle 2 is located on the top of the placement chamber 11.

[0034] In some embodiments, a circulating transfer mechanism 5 is installed on the base plate 6 to move test tubes 7 containing tumor specimens within the placement chamber 11 and the refrigerated storage chamber 12. The circulating transfer mechanism 5 includes a transfer component 51, a synchronous reverse drive component 52, and a support component 53. The synchronous reverse drive component 52 for controlling the movement of the transfer component 51 is installed at the bottom of the base plate 6. The transfer component 51 for controlling the changing of test tubes 7 is installed at the bottom of the interior of the refrigeration chamber 1, and the transfer component 51 and the synchronous reverse drive component 52 are connected. The support component 53 is installed on the transfer component 51. A plurality of support components 53 for placing test tubes 7 are installed on the transfer component 51.

[0035] In the use of this invention, after tumor resection, the tumor specimen is added to a test tube 7 containing cell preservation solution. Then, the baffle 2 is flipped upward by the lever 3, and the test tube 7 containing the tumor specimen is placed in the support component 53 in the placement chamber 11. The synchronous reverse drive component 52 drives the transfer component 51 to operate. The operation of the transfer component 51 causes the support component 53 in the placement chamber 11 to move the test tube 7 containing the tumor specimen to the cold storage chamber 12 for storage. The above operation is repeated, and all the test tubes 7 of the same batch of tumor specimens are transferred to the cold storage chamber 12.

[0036] When it is necessary to remove test tube 7, the synchronous reverse drive component 52 works again to drive the transfer component 51 to move the test tube 7 stored in the cold storage compartment 12 back to the placement compartment 11; then the test tube 7 can be removed.

[0037] This invention, through the cooperation of the transfer component 51, the synchronous reverse drive component 52, and the bearing component 53, ensures the uniformity and stability of cooling during tumor specimen refrigeration and also protects the tumor specimen tubes. The partition 4 divides the interior of the refrigeration chamber 1 into two compartments, separating the test tubes 7 to be stored from those to be retrieved, facilitating access for operators and improving the device's practicality. The baffle 2 on the refrigeration chamber 1 effectively prevents contaminants from entering the test tubes 7, ensuring the quality of temporary tumor storage.

[0038] Example 2: In some embodiments, such as Figures 4-6 As shown, in a preferred embodiment of this utility model, the synchronous reverse drive assembly 52 includes a rotation drive assembly, a drive gear 522, a driven gear 523, a worm gear 524, and a worm 525. The rotation drive assembly is fixedly installed on the bottom inner wall of the refrigeration housing 1. The drive gear 522 is rotatably connected to the bottom left side of the base plate 6, and the driven gear 523 is rotatably connected to the bottom right side of the base plate 6. The drive gear 522 and the driven gear 523 are meshed together. The bottom center of the drive gear 522 is fixedly connected to the worm gear 524. The output end of the rotation drive assembly is connected to one end of the worm 525. The worm gear 524 and the worm 525 are meshed together.

[0039] The rotation drive assembly uses a motor 521, which is fixedly installed on the bottom inner wall of the refrigeration box 1 and located below the base plate 6. The output end of the motor 521 is fixedly connected to one end of the worm gear 525.

[0040] The material transfer assembly 51 includes a left turntable 511, a right turntable 512, a U-shaped limiting groove 513, and a figure-eight sliding groove 514. The left turntable 511 is rotatably mounted on the top left side of the base plate 6 and is fixedly connected to the drive gear 522. The right turntable 512 is rotatably mounted on the top right side of the base plate 6 and is fixedly connected to the driven gear 523. Multiple U-shaped limiting grooves 513 are provided on the circumferential sides of both the left turntable 511 and the right turntable 512, and the multiple U-shaped limiting grooves 513 are distributed circumferentially at equal intervals on both the left turntable 511 and the right turntable 512. A figure-eight sliding groove 514 is provided on the top of the base plate 6. The middle part of the figure-eight sliding groove 514 is the junction of the placement chamber 11 and the cold storage chamber 12. The figure-eight groove 514 has two symmetrical protrusions in the middle. These protrusions can prevent the bearing component 53 from sliding on the inner circumference of the left side of the figure-eight groove, so that the bearing component 53 can only slide from the left side of the figure-eight groove into the right side.

[0041] In this invention, medical personnel insert a test tube 7 containing cell preservation solution into the support assembly 53; then, the motor 521 is started, and the motor 521 drives the worm gear 525 to rotate, which in turn drives the worm wheel 524 to rotate. The driving gear 522 rotates together with the worm wheel 524, and the driving gear 522 drives the driven gear 523 to rotate synchronously in the opposite direction. During this process, the driving gear 522 drives the left turntable 511 to rotate, and the driven gear 523 drives the right turntable 512 to rotate.

[0042] When the support component 53 in the placement chamber 11 slides to the middle of the figure-eight groove 514, the support component 53 slides from the U-shaped limiting groove 513 on the right turntable 512 into the U-shaped limiting groove 513 on the left turntable 511 in the cold storage chamber 12; the drive gear 522 continues to rotate, driving the left turntable 511 to rotate; when the support component 53 is fully inserted into the cold storage chamber 12, the tumor specimen can be stored.

[0043] When it is necessary to remove the test tube 7 from the refrigerated storage compartment 12, the motor 521 then operates again, causing the carrier component 53 to slide from the U-shaped limiting groove 513 on the left turntable 511 in the refrigerated storage compartment 12 back into the U-shaped limiting groove 513 on the right turntable 512 in the placement compartment 11, so that medical staff can remove the test tube 7 containing the tumor specimen from the sleeve 531.

[0044] Example 3: In some embodiments, such as Figures 4-6As shown, the bearing assembly 53 includes a sleeve 531, a retaining ring 532, and an elliptical sliding block 533. The retaining ring 532 is fixedly installed on the outer side of the middle part of the sleeve 531, and the elliptical sliding block 533 is fixedly installed on the bottom of the sleeve 531. The retaining ring 532 is slidably connected to the U-shaped limiting groove 513, and the elliptical sliding block 533 is slidably connected to the figure-eight sliding groove 514. The inner diameter of the sleeve 531 is larger than the outer diameter of the test tube 7, and the test tube 7 is inserted into the sleeve 531.

[0045] In this invention, medical personnel insert a test tube 7 containing cell preservation solution into the sleeve 531; then, the motor 521 rotates the right turntable 512; when the elliptical sliding block 533 in the placement chamber 11 slides to the middle of the figure-eight groove 514, the elliptical sliding block 533 drives the retaining ring 532 to slide from the U-shaped limiting groove 513 on the right turntable 512 to the U-shaped limiting groove 513 on the left turntable 511 in the cold storage chamber 12; the left turntable 511 rotates; when the sleeve 531 is fully inserted into the cold storage chamber 12, the tumor specimen can be stored.

[0046] When it is necessary to remove the test tube 7 from the cold storage compartment 12, the motor 521 will work again, causing the elliptical sliding block 533 to drive the retaining ring 532 to slide from the U-shaped limiting groove 513 on the left turntable 511 in the cold storage compartment 12 to the U-shaped limiting groove 513 on the right turntable 512 in the placement compartment 11. Medical staff can then remove the test tube 7 containing the tumor specimen from the sleeve 531.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
