[0026] The utility model provides a specimen fixing device. Figures 1 to 4 A specific embodiment of the present invention is provided.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a specimen fixing device 100, comprising a base 1, a plurality of clamping mechanisms 2 and a plurality of pressing mechanisms 3, wherein the base 1 is provided with a plurality of clamping stations 11 at intervals, and the plurality of clamping mechanisms 2 are all provided on the base 1, and each of the clamping mechanisms 2 is provided in a one-to-one correspondence with the clamping station 11, and the pressing mechanism 3 is provided correspondingly on one side of the clamping mechanism 2, and the clamping mechanism 2 comprises a clamping portion 21, and the clamping portion 21 has a fixed clamping groove for a filter paper containing a specimen to extend into, and the pressing mechanism 3 comprises a pressing portion 32 movably provided relative to the base 1 to control the opening and closing of the clamping portion 21.

[0028] In the utility model, a plurality of clamping stations 11 are arranged at intervals on the base 1, and the plurality of clamping mechanisms 2 are all arranged on the base 1, and each of the clamping mechanisms 2 is arranged in one-to-one correspondence with the clamping station 11, and the pressing mechanism 3 is correspondingly arranged on one side of the clamping mechanism 2, and the clamping mechanism 2 includes a clamping portion 21, and the clamping portion 21 has a clamping groove for the filter paper containing the specimen to extend into, and the pressing mechanism 3 includes a pressing portion 32 movably arranged relative to the base 1 to control the opening and closing of the clamping portion 21. When multiple specimens need to be fixed at the same time during the treatment process, the operator only needs to press the pressing portion 32 to control the opening and closing of the clamping portion 21, and then extend the multiple filter papers into and fix them on the clamping grooves respectively, and then place the multiple specimens on each of the filter papers respectively, and each of the specimens is fixed on each of the clamping stations 11 accordingly, thereby avoiding the problem of mixing up the specimens after the treatment. The specimen fixing device 100 provided by the utility model solves the problem that the existing fixing equipment may confuse specimens when fixing multiple specimens at the same time.

[0029] It should be noted that the operator can paste a label identifying the content of the specimen on each of the clamping mechanisms 2 to identify the specimen on the filter paper fixed by each of the clamping mechanisms 2 .

[0030] The method of fixing the filter paper by the clamping part 21 is not limited, as long as the clamping part 21 has a clamping groove for the filter paper to be inserted and fixed. For example, in some embodiments, Figure 1 As shown, the clamping part 21 is rotatably mounted on the base 1 along the axis extending in the x direction, and the clamping end of the clamping part 21 can form the clamping groove with the end face of the base 1. In this arrangement, the clamping groove is formed by the cooperation between the clamping part 21 and the end face of the base 1 to clamp the filter paper. Compared with the prior art in which two clamping parts 21 are provided, the two clamping parts 21 are close to each other to clamp the filter paper. On the one hand, the structure is simpler and the cost is lower. On the other hand, the filter paper is fitted with the end face of the base 1 to prevent the liquid in the specimen placed on the filter paper from spreading around.

[0031] Furthermore, the specific structure of the clamping mechanism 2 is not limited, as long as the clamping portion 21 can be opened to form the clamping groove. In some embodiments, Figure 1 As shown, the clamping mechanism 2 also includes an axial portion 22 and a driving portion 23 connected to the pressing portion 32, the axial portion 22 includes an inner ring 221, an outer ring 222 and a first elastic member 223, the inner ring 221 is installed on the base 1, the outer ring 222 is rotatably installed on the inner ring 221, and the outer ring 222 is connected to the inner ring 221 through the first elastic member 223, and the outer ring 222 is circumferentially connected to the driving portion 23 and the clamping portion 21. Specifically, the first elastic member 223 is a torsion spring, and the outer ring 222 is connected to the inner ring 221 through the torsion spring. Since the driving part 23 and the clamping part 21 are both connected to the outer ring 222, and the driving part 23 is connected to the pressing part 32, when the operator presses the pressing part 32, the driving part 23 is driven to move, and the outer ring 222 rotates to drive the clamping part 21 to open. After the filter paper is inserted into the clamping groove, the operator stops pressing the pressing part 32, and the outer ring 222 rotates in the opposite direction under the elastic force of the torsion spring, driving the clamping part 21 to close and clamp the filter paper.

[0032] Furthermore, in some embodiments, Figure 1 and Figure 3 As shown, the pressing mechanism 3 further includes a guide portion 31, the guide portion 31 has an active cavity with openings at both ends, the pressing portion 32 is movably arranged in the active cavity along the length direction of the guide portion 31, the pressing portion 32 includes a pressing section 321 and a connecting section 322, the pressing section 321 extends from the opening at one end of the guide portion 31 away from the base 1, the connecting section 322 extends from the opening at the other end of the guide portion 31 and is rotatably connected to the driving portion 23, and the axial direction of the rotatable connection of the connecting section 322 is parallel to the axial direction of the rotation of the outer ring 222. In this arrangement, since the connecting section 322 of the pressing portion 32 is rotatably connected to the driving portion 23, when the operator presses the pressing portion 32, the pressing portion 32 moves in the active cavity along the pressing direction, driving the driving portion 23 to move, thereby causing the outer ring 222 to rotate and drive the clamping portion 21 to open.

[0033] Specifically, Figure 1As shown, the driving portion 23 includes a first connecting portion 231 and a second connecting portion 232 that are rotatably connected to each other, the first connecting portion 231 is rotatably connected to the connecting segment 322, and the second connecting portion 232 is connected to the outer ring 222. The driving portion 23 is set to a multi-segment structure to avoid interference between the connection between the driving portion 23 and the outer ring 222 on the movement of the pressing portion 32, thereby making the movement of the pressing portion 32 smoother.

[0034] Before placing the filter paper, the operator needs to press the pressing portion 32 with one hand and take the specimen with the other hand, which is inconvenient. In order to improve efficiency, in some embodiments, Figure 3 and Figure 4 As shown, the pressing mechanism 3 also includes a locking assembly 33, and the locking assembly 33 includes a main body 331 and a locking portion 332. The main body 331 is rotatably mounted on the pressing portion 32, and the locking portion 332 is connected to the main body 331. The inner side wall of the guide portion 31 is provided with a matching groove 311, and the guide portion 31 has a first guide surface 312 for guiding the locking portion 332 to slide into the matching groove 311 when pressed, and the matching groove 311 has a limiting wall 3111 that can limit the locking portion 332 from moving in a direction opposite to the pressing direction. When the locking portion 332 is pressed against the locking cam 312, the locking portion 332 is moved into the locking cam 311. The locking portion 332 is guided into the locking cam 311 by the first guide surface 312 of the inner wall of the guide portion 31. The locking portion 332 is restricted to move in the direction opposite to the pressing direction. The locking portion 332 is restricted to move in the direction opposite to the pressing direction. The driving portion 23 is prevented from moving in the direction opposite to the pressing direction. The outer ring 222 is prevented from rotating under the elastic force of the torsion spring, thereby driving the clamping portion 21 to move in the direction close to the base 1, thereby closing the clamping portion 21. Therefore, the operator only needs to press once to make the locking portion 332 slide into the matching groove 311, and then stop pressing to complete other tasks, thereby improving work efficiency.

[0035] Furthermore, when the operator places the filter paper on the clamping station 11, the clamping portion 21 needs to be closed to clamp the filter paper. At this time, the locking portion 332 should be separated from the matching groove 311 and move in the direction opposite to the pressing direction, so that the pressing portion 32 and the driving portion 23 move in the direction opposite to the pressing direction. Therefore, in some embodiments, Figure 4As shown, the guide portion 31 also has a second guide surface 313 for guiding the locking portion 332 to slide out of the matching groove 311. Specifically, the second guide surface 313 can guide the locking portion 332 to move a certain distance in the pressing direction and slide out of the matching groove 311 along the groove wall on the side opposite to the limiting wall 3111. The operator only needs to press the pressing portion 32 again to make the locking portion 332 slide out of the matching groove 311, thereby making the outer ring 222 rotate under the elastic force of the torsion spring, and driving the clamping portion 21 to close.

[0036] It should be noted that the shaft portion connecting the main body 331 and the pressing portion 32 is semicircular. When the operator presses the pressing portion 32, the locking portion 332 is movably arranged in an inclined direction under the guidance of the first guide surface 312, and then swings under the influence of gravity and slides into the matching groove 311; similarly, when the operator presses the pressing portion 32 again, the locking portion 332 is guided by the second guide surface 313, swings under the influence of gravity, and slides out of the matching groove 311.

[0037] In some embodiments, Figure 3 As shown, the connecting section 322 is provided with a second elastic member 34, and a limiting section 323 is convexly provided on the circumferential side of the connecting section 322, and the second elastic member 34 is located between the limiting section 323 and the bottom of the guide portion 31. In this way, when the operator presses the pressing portion 32, the connecting section 322 and the limiting section 323 move along the pressing direction, and the second elastic member 34 is in a compressed state. When the operator stops pressing, the second elastic member 34 drives the pressing portion 32 to move in the direction opposite to the pressing direction under the action of elastic force, without relying on the elastic force of the torsion spring to drive the driving portion 23 to move, and drives the pressing portion 32 to move, so that the outer ring 222 rotates at a faster speed under the elastic force of the torsion spring, and then the clamping portion 21 is closed at a faster speed.

[0038] Specifically, in some embodiments, Figure 1 As shown, the specimen fixing device 100 further includes a fixing portion 4, the fixing portion 4 is arranged on the base 1, and the pressing mechanism 3 is installed on a side of the fixing portion 4 close to the clamping mechanism 2. In this way, the fixing portion 4 and the base 1 can be integrally formed, and the pressing mechanism 3 is connected to the side of the fixing portion 4. Since the pressing mechanism 3 and the side of the fixing portion 4 have a large contact area, the connection between the pressing mechanism 3 and the fixing portion 4 is more secure, and thus the connection between the pressing mechanism 3 and the base 1 is more secure.

[0039] When the specimen is placed on the filter paper fixed in the clamping groove, some liquid on the specimen may spread around on the base 1, resulting in mutual contamination between the specimens. In order to avoid specimen contamination, in some embodiments, such as Figure 2 As shown, the base 1 is provided with a plurality of receiving grooves 12, each of which corresponds to the clamping station 11, and the receiving groove 12 is located on one side of the clamping groove. In this way, the specimen is placed in the receiving groove 12 to prevent the liquid in the specimen from flowing to other specimens and causing contamination.

[0040] During the treatment process, various treatment instruments are scattered around the base 1. In order to prevent the treatment instruments from interfering with the fixed placement of the specimen, in some embodiments, the specimen fixing device 100 further includes a shell, which is arranged on the base 1, and a receiving cavity is arranged in the shell. The multiple clamping mechanisms 2 are located in the receiving cavity. One side of the shell is provided with multiple insertion ports at intervals, and the multiple insertion ports are connected to the receiving cavity so that the filter paper containing the specimen can be inserted and fixed on the clamping groove. The specimen in the receiving cavity is protected by the shell to prevent the specimen from being interfered with and contaminated by other treatment machines.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
