[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] See also Figure 1 to Figure 3 The specimen liquid storage and retrieval device of the utility model comprises a support frame 1, on which a high-level bucket 2, a specimen volume measuring component and a dosage proportioning component are sequentially arranged from top to bottom;

[0032] The dosage proportioning assembly includes a support seat 61 arranged on the support frame 1, and a rotating plate 62 rotatably connected to the support seat 61, one end of the rotating plate 62 is provided with a first proportioning barrel 63, and the other end is provided with a second proportioning barrel 64, wherein the ratio of the arm length of one end of the rotating plate 62 located at the second proportioning barrel 64 to the support seat 61 and the arm length of the other end of the rotating plate 62 to the support seat 61 is 1:9;

[0033] The specimen volume calculation assembly includes an overflow bucket 71, a collection slot plate 72 sleeved on the periphery of the overflow bucket 71, and a drainage slot plate 73 extending from the edge of the collection slot plate 72 toward the opening direction of the first proportioning bucket 63;

[0034] A first discharge pipe 4 and a second discharge pipe 5 are provided at the bottom of the high-level barrel 2 . The outlet end of the first discharge pipe 4 is arranged corresponding to the overflow barrel 71 , and the outlet end of the second discharge pipe 5 is arranged corresponding to the second proportioning barrel 64 .

[0035] It can be understood that by setting up a specimen volume measurement component, rapid measurement of the specimen volume can be achieved. When measuring, it is only necessary to first fill the overflow bucket 71 with formalin through the first discharge pipe 4, and then put the specimen liquid into the overflow bucket 71. The volume of the overflowed formalin is the volume of the specimen.

[0036] In addition, the overflowed formalin will flow into the collecting trough plate 72 at the periphery of the overflow barrel 71, and be discharged into the first proportioning barrel 63 under the guidance of the drainage trough plate 73. At this time, the medical staff can add formalin into the second proportioning barrel 64 through the second discharge pipe 5. Thanks to the ingenious 1:9 design of the lever arm length of the rotating plate 62, when the liquid volume in the second proportioning barrel 64 reaches nine times that of the first proportioning barrel 63, the rotating plate 62 will automatically adjust to a horizontal state, which means that the total amount of liquid in the first proportioning barrel 63 and the second proportioning barrel 64 is exactly ten times the required specimen volume. The entire configuration process does not require tedious calculations and is simple and intuitive.

[0037] For details, see Figure 3 , the rotating plate 62 is provided with a slot inside, a rotating shaft 8 is fixed inside the slot, the rotating plate 62 is rotatably connected to the support seat 61 via the rotating shaft 8, and the rotating shaft 8 is located at a 1 / 9 segment position of the overall length of the rotating plate 62. By placing the rotating shaft 8 at 1 / 9 of the length of the rotating plate 62, when the rotating plate 62 rotates, the movement range of one end thereof will be nine times that of the other end. This design ingeniously realizes the automatic proportional distribution of the liquid volume between the first proportioning barrel 63 and the second proportioning barrel 64, without the need for manual calculation or adjustment by medical staff.

[0038] Furthermore, mounting grooves are respectively provided on the end surfaces at opposite ends of the rotating plate 62, and the first proportioning barrel 63 and the second proportioning barrel 64 are movably connected in the mounting grooves of the rotating plate 62, and the two proportioning barrels can swing within a certain range. Therefore, even if the rotating plate 62 is tilted, the first proportioning barrel 63 and the second proportioning barrel 64 can always be perpendicular to the ground under the action of gravity, ensuring that the openings of the two are facing upward, and can better receive the injection of formalin.

[0039] It should be noted that, in this embodiment, the specifications of the first proportioning barrel 63 and the second proportioning barrel 64 are consistent, ensuring that when the volume of the liquid in the second proportioning barrel 64 is nine times the volume of the liquid in the first proportioning barrel 63, the rotating plate 62 remains horizontal, avoiding inaccurate configuration of the two proportioning barrels due to structural differences.

[0040] For further information, see Figure 3, the two sides of the support seat 61 are provided with stop blocks 9 extending upwardly and tilted, and the two stop blocks 9 are arranged corresponding to the bottom of the rotating plate 62 and keep a certain gap therefrom. It can be understood that by setting the stop blocks 9, the rotating plate 62 can only tilt at a certain angle, preventing the rotating plate 62 from tilting too much, resulting in the opening of the first proportioning barrel 63 not being able to align with the drainage slot plate 73, or the opening of the second proportioning barrel 64 not being able to align with the outlet end of the second discharge pipe 5.

[0041] For further information, see Figure 2 The bottom of the overflow bucket 71 is connected to a liquid level tube 10, and a liquid level sensor 11 is provided at the end of the liquid level tube 10. The first discharge pipe 4 is provided with a first electrically controlled valve 41. When the first electrically controlled valve 41 is opened, the liquid level sensor 11 is used to detect the change of the liquid level in the liquid level tube 10 in real time, and automatically close the first electrically controlled valve 41 when the liquid level in the liquid level tube 10 is equal to the opening end face of the overflow bucket 71, and stop the injection of formalin. At this time, medical staff can place the specimen in the overflow bucket 71. When the specimen is completely submerged in the overflow bucket 71, the volume of the overflowed formalin is the volume of the specimen.

[0042] Specifically, in this embodiment, the collecting slot plate 72 is annular, the drainage slot plate 73 is integrally formed on one side of the collecting slot plate 72 and is L-shaped, the end of the drainage slot plate 73 points to the opening of the first proportioning barrel 63, specifically, the upper end surface of the collecting slot plate 72 is provided with an annular groove that is the same as its own trajectory, the upper end surface of the drainage slot plate 73 is provided with an L-shaped groove that is the same as its own trajectory, and the L-shaped groove is connected to the annular groove, thereby forming a continuous liquid flow path. In actual application, when the specimen is put into the overflow barrel 71, the overflowed formalin can flow into the annular groove of the collecting slot plate 72, and enter the first proportioning barrel 63 along the L-shaped groove of the drainage slot plate 73 for collection.

[0043] Furthermore, the bottom surface of the annular groove is inclined toward the L-shaped groove, and gravity is used to help the liquid flow into the L-shaped groove faster, and then into the first proportioning barrel 63. This inclined design reduces the retention time of the liquid in the annular groove and improves the liquid transfer efficiency of the entire device.

[0044] For further information, see Figure 4 The bottom of the overflow bucket 71 is connected to a first manual valve 12 and a third discharge pipe 13 connected to the first manual valve 12, and the outlet end of the third discharge pipe 13 is arranged corresponding to the second proportioning bucket 64. It can be understood that when the volume measurement of the specimen is completed, the first manual valve 12 can be opened to introduce the remaining formalin in the overflow bucket 71 into the second proportioning bucket 64 through the third discharge pipe 13 to avoid waste.

[0045] When the remaining formalin in the overflow barrel 71 is completely discharged into the second proportioning barrel 64, the formalin in the high-level barrel 2 is introduced into the second proportioning barrel 64 through the second discharge pipe 5 for replenishment until the rotating plate 62 is in a horizontal state, and the injection of formalin is stopped. At this time, the formalin in the first proportioning barrel 63 and the second proportioning barrel 64 is close to 10 times the volume of the specimen, thereby achieving an accurate proportion of the specimen and formalin.

[0046] In addition, in this embodiment, the bottom surface of the overflow bucket 71 is conical, which is conducive to the discharge of the liquid in the overflow bucket 71 and avoids accumulation inside.

[0047] Combination Figure 1 and Figure 4 As shown, the support frame 1 is provided with an infrared sensor 14, and the second discharge pipe 5 is provided with a second electrically controlled valve 51. When the second electrically controlled valve 51 is opened, the infrared sensor 14 is used to detect the rotation angle change of the rotating plate 62 in real time, and automatically close the second electrically controlled valve 51 when it is detected that the rotating plate 62 is in a horizontal state. This design can effectively prevent the second discharge pipe 5 from adding excessive formalin into the second proportioning barrel 64, and ensure the accuracy of the liquid configuration in the second proportioning barrel 64.

[0048] In addition, it should be explained that only when the rotating plate 62 is in a horizontal state, the distance from the infrared light emitted by the infrared sensor 14 to the rotating plate 62 is the shortest. Based on this, the change in the rotation angle of the rotating plate 62 can be detected.

[0049] Furthermore, a second manual valve 631 is provided at the bottom of the first proportioning barrel 63, and a third manual valve 641 is provided at the bottom of the second proportioning barrel 64. After the second manual valve 631 and the third manual valve 641 are opened, formalin in the corresponding proportioning barrel can be taken out. Furthermore, the bottom surfaces inside the first proportioning barrel 63 and the second proportioning barrel 64 are conical, which is conducive to the discharge of the internal liquid and avoids accumulation inside.

[0050] For further information, see Figure 1, a collecting assembly is provided below the dosage proportioning assembly, and the collecting assembly includes a collecting plate 15 and a collecting barrel 18, the collecting plate 15 is fixedly connected to the supporting frame 1, the upper end surface of the collecting plate 15 is provided with a drainage groove 16 corresponding to the first manual valve 12 and the second manual valve 631, the lower end surface of the collecting plate 15 is provided with a total discharge pipe 17 connected with the drainage groove 16, and the collecting barrel 18 is provided below the total discharge pipe 17. It can be understood that when the first manual valve 12 and the second manual valve 631 are opened, the formalin flowing out of the first proportioning barrel 63 and the second proportioning barrel 64 can flow along the drainage groove 16, and finally be discharged from the total discharge pipe 17 to the collecting barrel 18 for collection, and at this time, the specimen can be placed in the collecting barrel 18 to complete the soaking and storage of the specimen.

[0051] Furthermore, the drainage groove 16 is V-shaped, which can promote formalin to flow into the main discharge pipe 17 more quickly and smoothly.

[0052] like Figure 1 As shown, the top of the high-position barrel 2 is threadedly connected with a sealing cover 3. When formalin needs to be added to the high-position barrel 2, the sealing cover 3 can be opened by gently rotating it, making the adding process simple and smooth. When not in use, the sealing cover 3 can tightly seal the opening of the high-position barrel 2, effectively preventing liquid leakage and the entry of external contaminants, and ensuring the purity and safety of the liquid in the barrel.

[0053] Working principle: When the specimen needs to be immersed, the first electrically controlled valve 41 of the first discharge pipe 4 is first opened, so that the formalin inside the high-level bucket 2 flows into the overflow bucket 71 through the first discharge pipe 4, and the height of the formalin is detected by the liquid level sensor 11. When the liquid level sensor 11 detects that the liquid level of the formalin is level with the top of the overflow bucket 71, the injection of formalin is stopped, and the specimen is placed in the overflow bucket 71. At this time, part of the formalin will overflow the overflow bucket 71 and flow into the overflow bucket 71. The collecting trough plate 72, when the specimen is completely immersed in the overflow bucket 71, the formalin overflowing from the overflow bucket 71 is the volume of the specimen, and the formalin overflowing from the overflow bucket 71 flows into the first proportioning bucket 63 through the drainage trough plate 73. At this time, the volume of formalin in the first proportioning bucket 63 is the volume of the specimen, and the rotating plate 62 is in a tilted state. At this time, the remaining formalin in the overflow bucket 71 is opened by opening the first manual valve 12 outside the third discharge pipe 13, so that the formalin flows out from the third discharge pipe 13. The material pipe 13 flows into the second proportioning barrel 64. When all the formalin in the overflow barrel 71 flows into the second proportioning barrel 64, the second electrically controlled valve 51 outside the second discharge pipe 5 is opened, and the formalin in the high-level barrel 2 is added to the second proportioning barrel 64 through the second discharge pipe 5, so that the rotating plate 62 gradually rotates to a horizontal state. When the rotating plate 62 is in a horizontal state, the infrared sensor 14 transmits a signal to close the second electrically controlled valve 51 to stop the injection of formalin. At this time, the first proportioning barrel 64 is The formalin in the barrel 63 and the second proportioning barrel 64 adds up to 10 times the volume of the specimen on the rotating rack, and the volume ratio of the specimen is one to ten, achieving an accurate ratio of specimen to formalin. Finally, open the second manual valve 631 and the third manual valve 641 to discharge the formalin in the first proportioning barrel 63 and the second proportioning barrel 64 to the collecting plate 15, and finally discharge it to the collecting barrel 18 through the main discharge pipe 17 on the collecting plate 15. At this time, put the specimen into the collecting barrel 18 to complete the immersion of the specimen.

[0054] In summary, the specimen liquid storage and retrieval device in the above-mentioned embodiment of the utility model collects formalin overflowing from the overflow barrel 71 through the first proportioning barrel 63, and then adds formalin into the second proportioning barrel 64 through the second discharge pipe 5. Thanks to the ingenious 1:9 design of the lever arm length of the rotating plate 62, when the liquid volume in the second proportioning barrel 64 reaches nine times that of the first proportioning barrel 63, the rotating plate 62 will automatically adjust to a horizontal state, which means that the total amount of liquid in the first proportioning barrel 63 and the second proportioning barrel 64 is exactly ten times the required specimen volume. The entire configuration process does not require tedious calculations and is simple and intuitive.
