[0035] Referring to Figures 1-7 , a sample fixing and storage device for the pathology department, including a sample box 4, and further including:

[0036] A storage box 11, in the storage box 11, vertical limit plates 10 are provided at all four corners;

[0037] A storage rack 1, the storage rack 1 is of a hollow structure, the sample boxes 4 are received in a rectangular array in the storage rack 1, the storage rack 1 is placed in the storage box 11, limit clamping plates 9 are installed at the four corners of the outer wall of the storage rack 1, and vertical clamping grooves penetrating up and down are formed on the inner sides of the limit clamping plates 9 to slide vertically with the limit plates 10. A storage cavity is provided inside the storage rack 1, a partition board 3 of a hollow structure is installed on the center line of the storage cavity, arc rods 2 are linearly and equidistantly installed on the partition board 3, and placement slots for the sample boxes 4 are formed in an array between adjacent arc rods 2, the inner wall of the storage cavity and the partition board 3. The partition board 3 is installed with the inner wall of the storage cavity, the arc rods 2 are installed with the partition board 3, and each arc rod 2 is vertically symmetric with respect to the corresponding partition board 3;

[0038] A top cover 5, the top cover 5 presses on the top of the storage box 11, the top cover 5 is detachably installed with the storage box 11, a buckle plate is rotated on the side wall of the top cover 5 through a rotating shaft, and a hanging ear for cooperating with the buckle plate is installed on the side wall of the storage box 11 to form a detachable installation of the top cover 5 and the storage box 11; a plurality of limit rods 8 for vertically limiting and inserting into the upper end surface of the storage rack 1 are vertically provided on the lower end surface of the top cover 5, and guide holes 6 adapted to the outer diameter of the sample boxes 4 are provided on the top cover 5 corresponding to the arrayed sample boxes 4. The limit rods 8 are provided on both sides of each guide hole 6, and one-way plates 7 are rotatably connected to the limit rods 8 on both sides through rotating shafts. The extending ends of the two one-way plates 7 abut against each other, and both one-way plates 7 are located directly below the guide hole 6 to block the guide hole 6 from the lower end surface of the top cover 5. The upper end surface of the one-way plate 7 abuts against the lower end surface of the top cover 5, and the lower end surface of the one-way plate 7 is connected to the limit rod 8 through a spring;

[0039] The pressing plate 12 is correspondingly arranged directly above the sample box 4 of the array. The pressing plate 12 is arranged in the storage rack 1. The pressing plate 12 is rotationally limited in the vertical direction to limit the floating of the sample box 4. The pressing plate 12 is rotationally installed on the partition plate 3 through shaft limiting. The bottom of the pressing plate 12 is connected to the partition plate 3 through a spring so that the pressing plate 12 is in a horizontal state, and the extending end of the pressing plate 12 is located on the vertical channel of the sample box 4;

[0040] The storage box 11 is filled with formalin solution. When the sample box 4 is full, the liquid level of the formalin solution in the storage box 11 is above the sample box 4 and below the active area of the one-way plate 7, so that the sample box 4 is completely immersed in the formalin solution. At the same time, it also reduces the possibility of the formalin solution splashing out from the guiding hole 6 during the process of the one-way plate 7 rotating vertically to reset.

[0041] The working process of this embodiment is as follows:

[0042] a: Insert the sample box 4 with human samples stored inside through the guiding hole 6. At the same time, the two one-way plates 7 at the bottom of the guiding hole 6 rotate downward along the shaft; the sample box 4 continues to be inserted downward. The bottom of the sample box 4 pushes the pressing plate 12 downward, and the pressing plate 12 rotates vertically along the shaft. The sample box 4 continues to be pushed downward, and the sample box 4 slides into the placement groove formed between the arc rod 2, the hollow partition plate 3, and the hollow storage rack 1. At the same time, the extending end of the pressing plate 12 abuts against the side surface of the sample box 4; the sample box 4 continues to be pushed downward, and the extending end of the pressing plate 12 moves to the upper end surface of the sample box 4 and remains horizontal under the action of the spring, so that the sample box 4 is stuck between the pressing plate 12 and the bottom of the storage rack 1; at the same time, the user withdraws the operating tool from the guiding hole 6, and the two one-way plates 7 reset under the action of the spring, that is, the placement of the sample box 4 is completed;

[0043] In this process, through the setting of the one-way plate 7, the sample box 4 can only be inserted into the guiding hole 6 unidirectionally. After insertion, the one-way plate 7 resets. Under the elastic force of the spring, the upper end surface of the one-way plate 7 abuts against the lower end surface of the top cover 5, sealing the guiding hole 6, reducing the volatilization of the high-concentration formalin solution in the storage box 11, improving the stability of the formalin solution for preserving human samples, and reducing the harm of the irritating volatile gas of formalin to medical staff; at the same time, through the setting of the pressing plate 12, using the elastic connection between the pressing plate 12 and the partition plate 3, the spring pulls the pressing plate 12, so that the pressing plate 12 has a tendency to maintain a horizontal pulling force, thereby balancing the upward floating force of the sample box 4 in the formalin solution, so that the sample box 4 is completely immersed in the formalin solution. The formalin solution passes through the hollow storage rack 1, the hollow partition plate 3, and the hollow sample box 4, and is in full contact with the human sample, improving the immersion effect of the sample box 4 in the formalin solution;

[0044] b: By releasing the snap connection structure between the top cover 5 and the storage box 11, then separating the top cover 5 from the storage box 11, the limit clamping plates 9 at the four corners slide upward along the limit plate 10, so that the storage rack 1 is taken out from the storage box 11, the sample box 4 is pulled out, and the pressing plate 12 rotates upward, thus realizing the removal of the sample boxes 4 distributed in multiple arrays;

[0045] In this process, by the lower end face of the top cover 5 abutting against the upper end face of the storage box 11, the sealing performance of the formalin solution is improved. The detachable connection between the top cover 5 and the storage box 11, and the movable connection between the storage rack 1 and the storage box 11 enable the storage box 11 to be completely taken out from the storage box 11, making it more convenient to take out the sample boxes 4 at one time and facilitating the treatment of the formalin solution. The setting of the combined structure is more convenient for the cleaning and disinfection treatment of each device; in the storage box 11, the limit clamping plates 9 at the four corners slide vertically with the limit plate 10 to limit the position of the storage rack 1 in the storage box 11. By the limit rods 8 at the corners of the top cover 5 abutting against the top of the storage rack 1, the floating force of the storage rack 1 in the storage box 11 is reduced, further making the guiding holes 6 in the rectangular array correspond to the placement slots of the sample boxes 4 in the rectangular array, improving the stability during the insertion process of the sample boxes 4.

[0046] Different from Embodiment 1:

[0047] Embodiment 2

[0048] Refer to Figures 1-7 , a pathological sample fixing and storing device, including a sample box 4, and further including:

[0049] A storage box 11, a top cover 5, and multiple storage racks 1;

[0050] There are multiple storage racks 1, and multiple storage racks 1 form a storage group. Limit clamping plates 9 are arranged at the four corners of the storage group for cooperation with the storage box 11. Jacks are arranged at the four corners of the top of the storage group. The limit rods 8 at the four corners of the bottom of the top cover 5 are inserted into the corresponding jacks so that the top cover 5 abuts against the storage group. Preferably, the multiple storage racks 1 are detachably connected. In this embodiment, preferably but not limited to, bolt connection;

[0051] The difference between this embodiment and Embodiment 1 is that: by releasing the snap connection structure between the top cover 5 and the storage box 11, then separating the top cover 5 from the storage box 11, the limit clamping plates 9 at the four corners slide upward along the limit plate 10, so that the storage group is taken out from the storage box 11, the sample box 4 is pulled out, and the pressing plate 12 rotates upward, thus realizing the removal of the sample boxes 4 distributed in multiple arrays;

[0052] In this process, the lower end face of the top cover 5 abuts against the upper end face of the storage box 11, improving the sealing performance of the formalin solution. The detachable connection between the top cover 5 and the storage box 11, as well as the movable connection between the storage group and the storage box 11, enable the storage box 11 to be completely taken out from within the storage box 11, making it more convenient to take out the sample box 4 at one time and facilitating the treatment of the formalin solution. The setting of the combined structure makes it more convenient to clean and disinfect each device. In the storage box 11, the limiting clamping plates 9 and the limiting plates 10 at the four corners slide vertically to limit the position of the storage group within the storage box 11. The limiting rods 8 at the corners of the top cover 5 abut against the top of the storage group to reduce the floating force of the storage group within the storage box 11, further making the guiding holes 6 in the rectangular array correspond to the placement slots of the sample boxes 4 in the rectangular array and improving the stability during the insertion of the sample boxes 4.
