DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-Figure 10 A constant temperature test tube rack for reproductive medicine comprises a test tube rack body 1, a plurality of test tube cavities 8 are penetrated through the upper surface of the test tube rack body 1, an outer insulation shell 2 is sleeved on the outer wall of the test tube rack body 1 and fixedly connected, a bottom cavity 9 is opened on the bottom surface of the outer insulation shell 2, a power supply 10 is fixedly connected to the bottom surface of the bottom cavity 9, an output end of the power supply 10 is electrically connected to a plurality of heating plates 15 through electric wires, the outer walls of the plurality of heating plates 15 are respectively fixedly connected to the bottom surfaces of the plurality of test tube cavities 8, a plurality of clamping components are connected to the upper surface of the outer wall of the test tube rack body 1, the upper surfaces of the plurality of clamping components are all connected to sealing components, and the plurality of sealing components are respectively matched with the inner walls of the plurality of test tube cavities 8.

[0032] The thermostatic test tube rack for reproductive medicine of the present invention is similar to the existing thermostatic test tube rack structure, such as a thermostatic test tube rack disclosed in the patent with announcement number CN219816333U. Figures 1 to 10As shown, when the constant temperature test tube rack for reproductive medicine in the present invention is used, first ensure that the power supply 10 has sufficient power, and then through an external PLC controller (it can also be carried by the bottom cavity 9 itself, not limited to the specific), and then through a number of wires, heat the several heating plates 15 respectively. After the heating plates 15 are heated, heat can be generated, and the inside of the test tube cavity 8 is heated when the heat is generated. After the heating temperature reaches the set standard, it stops and maintains a constant temperature. Because the power supply 10 heats the several heating plates 15 on the bottom surface of each test tube cavity 8 respectively, the temperature inside each test tube cavity 8 can be made more uniform, thereby avoiding the stored sperm and eggs being affected by different temperatures.

[0033] Because test tubes are of different thicknesses, test tubes of different thicknesses are likely to shake inside the test tube cavity 8 or even fall. In order to avoid such a situation, a clamping assembly is provided above the test tube rack body 1 to clamp and fix test tubes of different thicknesses.

[0034] In order to prevent debris from falling into some test tube cavities 8 where no test tubes are placed, which would affect the later storage of the test tubes, a sealing component is used to seal and shield between the test tube cavities 8 where no test tubes are placed and the clamping component.

[0035] Special mention should be made here:

[0036] 1. The power source 10 can be a rechargeable type or a detachable and replaceable battery. The specific type is not limited. The above-mentioned types are all very mature technologies at present, so they are not described in detail.

[0037] 2. PLC controller is also a very mature technology at present, so it will not be explained in detail.

[0038] 3. If not all test tubes are placed in some test tube cavities 8, the corresponding heating plates 15 can be selectively turned off through the PLC controller to save power.

[0039] 4. Stable heating. The specified temperature can be set through the PLC controller so that the heating plate 15 can only be heated to the specified temperature. A temperature sensor can also be set in the test tube cavity 8. When the temperature reaches the standard, the connection between the power supply 10 and the corresponding heating plate 15 can be cut off in time through the PLC controller.

[0040] 5. Although the test tubes are different in length in addition to thickness, the heating plate 15 generates heat that covers the entire test tube cavity 8, so the different lengths of the test tubes have no effect on maintaining a constant temperature, so no detailed description is given here.

[0041] As a preferred embodiment of the present invention, the clamping assembly includes a fixed ring 3, a rotating ring 4 and a plurality of movable assemblies. The upper surface of the fixed ring 3 is provided with a plurality of straight openings 25, the upper surface of the rotating ring 4 is penetrated with a plurality of oblique openings 28, the bottom surface of the fixed ring 3 is connected to the upper surface of the test tube rack body 1, the bottom surface of the rotating ring 4 is slidably connected to the upper surface of the fixed ring 3, the plurality of straight openings 25 are respectively matched and aligned with the plurality of oblique openings 28, the lower ends of the plurality of movable assemblies are respectively located at the connection points of the plurality of straight openings 25 and the oblique openings 28, the upper ends of the plurality of movable assemblies respectively penetrate the connection points of the plurality of straight openings 25 and the oblique openings 28, a test tube opening 19 is penetrated at the center of the fixed ring 3 and the rotating ring 4, the test tube opening 19 is connected to the test tube cavity 8, and the upper surface of the rotating ring 4 is connected to the sealing assembly.

[0042] More specifically, when it is necessary to clamp test tubes of different thicknesses, it is only necessary to open the sealing assembly first, and then insert the test tube from the test tube opening 19 of the fixed ring 3 and the rotating ring 4. After the test tube is inserted to a suitable depth, the rotating ring 4 is rotated. After the rotating ring 4 rotates, it will drive the multiple moving assemblies to move in the multiple straight openings 25 through the multiple oblique openings 28, and then the test tube located in the middle of the test tube opening 19 can be clamped from all sides during the movement along the straight openings 25 to prevent it from shaking.

[0043] As a preferred solution of the present invention, the moving component includes an extrusion fan 6 and a sliding rod 27, the lower end of the sliding rod 27 is located at the connection between the straight opening 25 and the oblique opening 28, and the outer wall of the sliding rod 27 is slidably connected to the connection between the straight opening 25 and the oblique opening 28, the upper end of the sliding rod 27 passes through the connection between the straight opening 25 and the oblique opening 28, and is fixedly connected to the bottom surface of the extrusion fan 6, and the bottom surface of the extrusion fan 6 is against the upper surface of the rotating ring 4.

[0044] More specifically, when the rotating ring 4 rotates, because the oblique mouth 28 and the straight mouth 25 always have only one connection point the size of the slide bar 27, when the rotating ring 4 rotates, the oblique mouth 28 will move the slide bar 27 along the straight mouth 25. Since the straight mouth 25 is vertically arranged with respect to the test tube mouth 19, the slide bar 27 and the extrusion fan 6 located outside the slide bar 27 can only move vertically toward the test tube mouth 19, so that the test tube located in the middle of the test tube mouth 19 can be clamped from the side.

[0045] As a preferred solution of the present invention, the bottom surface of the straight mouth 25 is provided with an anti-slip opening 24, and the bottom surfaces of one end of several sliding rods 27 located in the straight mouth 25 are fixedly connected with rectangular blocks 26, and the outer walls of several rectangular blocks 26 are slidably connected with the inner walls of several anti-slip openings 24 respectively.

[0046] More specifically, by providing the anti-slip opening 24 and the rectangular block 26, firstly, the slide bar 27 can be prevented from falling from the oblique opening 28 and the straight opening 25; secondly, the slide bar 27 and the extrusion fan 6 can be prevented from rotating when they move.

[0047] As a preferred solution of the present invention, the sealing assembly includes a cover plate 5, a sealing block 18, a buckle block 14 and a reset assembly, the bottom surface of the cover plate 5 is fixedly connected to the upper surface of the sealing block 18, the outer wall of the sealing block 18 is slidably connected to the inner wall of the upper end of the test tube mouth 19, one side of the outer wall of the cover plate 5 is connected to the reset assembly, the other end of the reset assembly is connected to the upper surface of the rotating ring 4, and the side of the cover plate 5 away from the reset assembly is fixedly connected to the buckle block 14.

[0048] More specifically, when there are no test tubes inside some test tube cavities 8, the cover plate 5, the sealing block 18 and the buckle block 14 can be rotated toward the test tube opening 19 through the reset assembly, and then the sealing block 18 can be inserted into the test tube opening 19, thereby preventing external debris from falling into the test tube opening 19.

[0049] When it is necessary to place a test tube inside the test tube opening 19, the seal block 18 and the cover plate 5 can be pulled out from the test tube opening 19 by simply depressing the detent block 14, and then the test tube opening 19 can be leaked out, so that the test tube can be placed normally.

[0050] As a preferred solution of the present invention, the reset assembly includes a connecting plate 12, a U-shaped block 13, a support rod 21 and two rotating blocks 20, the bottom surface of the U-shaped block 13 is fixedly connected to the upper surface of the rotating ring 4, the two ends of the support rod 21 are rotatably connected to the inner wall of the U-shaped block 13, the two rotating blocks 20 are both sleeved and rotatably connected to the outer wall of the support rod 21, the ends of the two rotating blocks 20 away from the support rod 21 are respectively fixedly connected to the two ends of one side of the connecting plate 12, and the other end of the connecting plate 12 is fixedly connected to one side of the cover plate 5.

[0051] More specifically, when the test tube mouth 19 needs to be sealed, the cover plate 5 is rotated. After the cover plate 5 is subjected to force, it will rotate downward with the connecting plate 12. After the connecting plate 12 rotates downward, it can rotate around the support rod 21 as the axis through the two rotating blocks 20, so that the opening of the test tube mouth 19 can be sealed; when the test tube mouth 19 needs to leak, the above steps can be reversed.

[0052] As a preferred solution of the present invention, a torsion spring 22 is sleeved on the outer wall of the support rod 21 , and two ends of the torsion spring 22 are fixedly connected to the connecting plate 12 and the U-shaped block 13 respectively.

[0053] More specifically, by providing the torsion spring 22 , under normal sealing conditions, the torsion spring 22 will press the connecting plate 12 and the cover plate 5 etc. into the test tube opening 19 , thereby preventing the cover plate 5 and the sealing block 18 etc. from falling out of the test tube opening 19 on their own.

[0054] As a preferred solution of the present invention, a plurality of connecting rings 11 are fixedly connected to the upper surface of the test tube rack body 1 , and the outer walls of the plurality of connecting rings 11 are respectively threadedly connected to the inner walls of the plurality of fixing rings 3 .

[0055] More specifically, by providing the connecting ring 11, the fixed ring 3 and the rotating ring 4 can be supported and limited to prevent the fixed ring 3 and the rotating ring 4 from shifting and falling; secondly, when the fixed ring 3 and the rotating ring 4 need to be disassembled, cleaned, or replaced, the operation can be more convenient.

[0056] As a preferred embodiment of the present invention, a rotating cavity 23 is formed on the upper surface of the fixed ring 3, and a plurality of moving rods 29 are connected to the bottom surface of the rotating ring 4. The other ends of the moving rods 29 are rotatably connected to a rotating wheel 30, and the side walls of the rotating wheels 30 are rollingly connected to the inner wall of the rotating cavity 23. One end of one of the moving rods 29 away from the rotating wheel 30 penetrates the rotating ring 4 and is fixedly connected to a turning knob 7. The moving rod 29 is also threadedly connected to the inner wall of the rotating ring 4, and the ends of the remaining moving rods 29 away from the rotating wheel 30 are fixedly connected to the bottom surface of the rotating ring 4.

[0057] More specifically, by providing the rotating chamber 23, the moving rod 29 and the rotating wheel 30, firstly, it can be ensured that the rotating ring 4 can rotate normally above the fixed ring 3; secondly, it can prevent the rotating ring 4 from falling off the fixed ring 3; finally, through the action of the twist knob 7 and one of the threaded moving rods 29, when the rotating ring 4 is rotated to adjust the spacing between the several extrusion fan blades 6, the rotating ring 4 and the fixed ring 3 can be locked, thereby preventing the rotating ring 4 from rotating by itself, thereby affecting the stable clamping of the test tube.

[0058] As a preferred solution of the present invention, a connecting tube 17 is fixedly connected to the bottom surface of the fixing ring 3, and the other end of the connecting tube 17 is fixedly connected to a bottom film 16. The outer wall of the bottom film 16 is slidably connected to the inner wall of the test tube cavity 8, and there is a certain distance between the connecting tube 17 and the test tube cavity 8.

[0059] More specifically, because the bottom surface of the test tube cavity 8 is kept at a constant temperature by the heating plate 15, when the test tube rack body 1 is moved from a high temperature place to a low temperature place (and vice versa), some small water droplets are likely to condense on the inner wall of the test tube cavity 8. In order to prevent these small water droplets from affecting the heating plate 15 below, the connecting tube 17 and the bottom film 16 are provided at this time, so that the condensed water droplets can be stored in the cavity between the connecting tube 17 and the test tube cavity 8, thereby avoiding affecting the heating plate 15 below; and when it is necessary to remove the fixed ring 3 and the rotating ring 4 from the inside of the test tube cavity 8, the bottom film 16 can also scrape the water droplets in the cavity between the connecting tube 17 and the test tube cavity 8 to the outside of the test tube cavity 8.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
