Description

Technical Field

[0001] The invention belongs to the technical field of human anatomy, and in particular relates to a device for preserving visceral specimens for human anatomy. Background Art

[0002] Specimens are animals, plants, minerals and other objects that have been processed in various ways for long-term preservation and display. Antiseptic treatment is a very important part of the specimen production process. It can prevent specimens from rotting, mildew or insects, thereby maintaining the original appearance and value of the specimens. Antiseptic treatment is of great significance for exhibitions, demonstrations, education, identification, textual research and other research. Preservatives such as formalin are widely used to preserve animal specimens because of their ability to denature proteins. They achieve the preservation effect by fixing animal tissues and organs such as muscles.

[0003] The patent with publication number CN115043079B discloses a visceral specimen preservation device for human anatomy, comprising: a support seat, a lifting plate, a storage component, an injection component, an extraction component, a storage component and a test tube component; when in use, the operator takes out the rubber layer and the outflow baffle inside the tube body, and then puts the visceral specimen into the tube body, and the visceral specimen can slide to the bottom of the tube body. At this time, the rubber layer and the outflow baffle are put back in place to complete the placement of the visceral specimen in the tube body. During the placement of the tube body in the placement groove, the third motor is operated to rotate the placement seat inside the storage seat. The high-speed rotation of the placement seat in the storage seat can centrifuge the visceral specimen in the tube body, which allows the moisture in the visceral specimen to be separated from the visceral specimen by centrifugation. After the centrifugation is completed, the storage seat is operated by the second motor. By rotating the rotating shaft, the upper and lower positions of the storage seat can be swapped, which allows the tube body to be inverted. After the tube body 1 is inverted, the water separated in the visceral specimen can flow out through the outflow baffle, which allows the visceral specimen to be separated from the water separated by centrifugation. After the water is separated, the lifting plate continues to move downward, so that the extraction needle can penetrate into the inner side of the rubber layer. At this time, the suction box works, which can extract the liquid in the tube body through the extraction needle and discharge it from the discharge pipe. After the water extraction is completed, the lifting plate moves up and rotates, so that the tube body can be aligned with one side of the injection needle. At this time, the lifting plate continues to move downward, so that the injection needle can penetrate into the inner side of the rubber layer. At this time, the injection box works, and the formalin solution in the storage box can be injected into the tube body through the injection needle. By separating the water in the visceral specimen and then injecting the formalin solution, the antiseptic effect of the visceral specimen can be effectively improved.

[0004] In the above technical solution, the position of the outflow baffle is fixed. If the visceral specimen is small, then during the subsequent centrifugation operation, the visceral specimen will move toward the top of the tube body during the centrifugation process, and the center of the visceral specimen will shift, affecting the centrifugal effect; if the visceral specimen is large, the outflow baffle will squeeze the visceral specimen, and during the subsequent centrifugation process, the visceral specimen cannot be fully centrifuged, causing the water in the visceral specimen to separate, resulting in poor use effect.

[0084] Example 1

[0085] This embodiment provides a device for preserving visceral specimens for human anatomy, such as Figure 1-20 As shown, it includes a workbench 5, and an visceral specimen fixing mechanism 1, a centrifugal mechanism 2, a liquid extraction mechanism 3 and an antiseptic mechanism 4 arranged on the workbench 5.

[0086] like Figure 1 , 4 As shown in FIG. 11 , a plurality of storage tanks 6 are used to store visceral specimens. The storage tanks 6 include a tank body 61, a leather plug 63 disposed at the opening of the tank body 61, and an outflow baffle 62 disposed in the tank body 61; wherein the outflow baffle 62 is used to limit the visceral specimens and is disposed in a receiving cavity formed between the outflow baffle 62 and the bottom of the tank body 61. It should be noted that the embodiment of the present invention does not limit the number of storage tanks 6. For example, the embodiment of the present invention is described by taking the number of storage tanks 6 as 3 as an example.

[0087] Specifically, the opening of the storage tank 6 is provided with a truncated cone-shaped connecting ring so as to be connected to the viscera specimen fixing mechanism 1 .

[0088] like Figure 4 As shown, the visceral specimen fixing mechanism 1 includes a fixing frame 11 for fixing each storage tank 6, and a storage space adjustment component for adjusting the position of the outflow baffle 62 located in the storage tank 6; wherein, a storage space adjustment component is respectively provided on the outside of each storage tank 6.

[0089] The fixing frame 11 includes a connecting frame 11a and a plurality of cylindrical shells 11b arranged on the connecting frame 11a; wherein the shell 11b is used to place the storage tank 6; specifically, the lower end of the storage tank 6 passes through the shell 11b and is connected to the centrifugal mechanism 3.

[0090] like Figure 1 As shown, the connecting frame 11 a passes through the workbench 5 and is connected to the turning mechanism 7 .

[0091] In actual use, a groove is provided on the outer side of the truncated cone-shaped connecting ring of the storage tank 6, and correspondingly, a convex ring matching the groove is provided at the opening of the shell 11b, so as to limit the storage tank 6 inside the shell 11b, and the storage tank 6 is rotatably connected to the shell 11b.

[0092] like Figure 9-14 As shown, the accommodating space adjustment assembly includes a magnetic ring 12, a threaded rod 13 and a first driving unit 14; wherein the first driving unit 14 includes a first bevel gear 14a, a second bevel gear 14b, a gear ring 14c and a driving gear 14d.

[0093] Specifically, the magnetic ring 12 is sleeved on the outside of the storage tank 12;

[0094] The threaded rod 13 is sleeved with the magnetic ring 12, and the threaded rod 13 is threadedly connected with the magnetic ring 12; the threaded rod 13 passes through the magnetic ring 12 and is fixedly connected with the first bevel gear 14a provided at the truncated cone-shaped connecting ring of the storage tank 6; specifically, the threaded rod 13 is integrally connected with the first bevel gear 14a provided at the opening of the storage tank 12. The first bevel gear 14a is plugged with the truncated cone-shaped connecting ring, and the first bevel gear 14a and the truncated cone-shaped connecting ring are rotatably connected.

[0095] The second bevel gear 14b is disposed at the opening of the storage tank 6 and is meshed with the first bevel gear 14a; Fig.14 As shown, a transmission gear is provided at the end of the second bevel gear 14b; the transmission gear is used to mesh with the gear ring 14c. Specifically, the second bevel gear 14b is plugged into the truncated cone-shaped connecting ring and the second bevel gear 14b is rotatably connected to the truncated cone-shaped connecting ring.

[0096] The gear ring 14c is disposed above the opening of the storage tank 6, and the gear ring 14c is rotatably connected to the storage tank 6. The gear ring 14c includes an inner gear ring and an outer gear ring;

[0097] Specifically, the inner gear ring is meshed with the transmission gear disposed at the end of the second bevel gear 14b, and the outer gear ring is meshed with the driving gear 14d rotatably disposed on the fixed frame 11; the driving gear 14d is disposed on the output end of the first motor (not shown in the figure). The first motor (not shown in the figure) is disposed on the fixed frame 11.

[0098] The working principle of the accommodating space adjustment component is as follows: after the first motor is energized, the driving gear 14d rotates, and then the driving gear 14d drives the gear ring 14c to rotate, and the inner gear ring of the gear ring 14c drives the second bevel gear 14b to rotate, and then the second bevel gear 14b drives the first bevel gear 14a to rotate. During the rotation of the first bevel gear 14a, the threaded rod 13 is driven to rotate. Since the threaded rod 13 is threadedly connected to the magnetic ring 12, during the rotation of the threaded rod 13, the magnetic ring 12 moves linearly in the vertical direction under the threaded limiting action of the threaded rod 13, thereby realizing the position adjustment of the magnetic ring 12.

[0099] During the movement of the magnetic ring 12 , under the effect of magnetic attraction, the outflow baffle 62 located in the storage tank 6 moves along with the movement of the magnetic ring 12 , thereby adjusting the size of the accommodating cavity formed between the outflow baffle 62 and the bottom of the tank body 61 .

[0100] The number of rotations and the direction of rotation of the driving gear 14 d can be controlled by turning the first motor on and off to control the moving distance and direction of the outflow baffle 62 , thereby achieving precise positioning of the outflow baffle 62 .

[0101] like Figure 2 ,as well as Figures 4 to 6 As shown, the turning mechanism 7 includes a rotating rod 71 and a fixing rod 72 ; wherein, a turning handle 75 is provided on the rotating rod 71 , so that the operator can grasp the turning handle 75 and then turn the visceral specimen fixing mechanism 1 180° through the rotating rod 72 .

[0102] One end of the rotating rod 71 is fixedly connected to the connecting frame 11 a , and the other end is provided with a fixed block 73 ; wherein the fixed block 73 includes a fixed shell 73 a , a pressing spring 73 b and a limiting ball 73 c ; the fixed shell 73 a is fixedly connected to the rotating rod 71 .

[0103] Among them, a pressing spring 73b and a limiting ball 73c are respectively provided at the upper and lower ends of the fixed shell 73a; specifically, one end of the pressing spring 73b is connected to the inner bottom surface of the fixed shell 73a, and the other end is fixedly connected to the limiting ball 73c.

[0104] The fixing rod 72 is horizontally arranged on the workbench, and a fixing groove 74 is provided at the end of the fixing rod 72 ; the fixing groove 74 is located directly below the rotating rod 71 .

[0105] The working principle of the flipping mechanism 7 is as follows: the operator holds the flipping handle 7, and then flips the rotating rod 71180°, so that the fixed block 73 is close to the fixed groove 74, until the fixed pressing spring 73b presses the limiting ball 73c into the fixed groove 74, thereby fixing the visceral specimen fixing mechanism 1;

[0106] After the viscera specimen fixing mechanism 1 is turned over, the viscera specimens set in the storage tank 6 can be centrifuged by the centrifugal mechanism 2 set on the fixing frame 11.

[0107] like Figure 4 As shown, the centrifugal mechanism 2 includes a transmission belt 21 and a rotating shaft 22 .

[0108] The transmission belt 21 is sleeved on the bottom end of each storage tank 6 and the bottom end of the rotating shaft 22; the upper end of the rotating shaft is rotatably connected to the connecting frame 11a, and the upper end of the rotating shaft is connected to the output end of the second motor (not shown in the figure); wherein the second motor (not shown in the figure) is arranged on the fixed frame 11.

[0109] In this way, when in use, the second motor is started to rotate the rotating shaft 22, which drives the transmission belt 21 to rotate, and then the transmission belt 21 drives each storage tank 6 to rotate, thereby realizing the centrifugal operation of the visceral specimens in the storage tank 6.

[0110] After the centrifugal operation is completed, the liquid at the centrifugal separation site is gathered at the leather plug 63. At this time, the liquid separated by the centrifugal operation can be discharged through the liquid extraction mechanism 3 arranged on the workbench 5.

[0111] like Figure 3 , Fig.15 , 16 As shown in FIG. 20 , the liquid pumping mechanism 3 includes a liquid pumping tube 31 , a limiting ring 32 , and two return rods 33 symmetrically arranged on both sides of the limiting ring 32 .

[0112] In actual application, the liquid extraction mechanism 3 includes a plurality of liquid extraction tubes 31, which correspond to the storage tanks 6 one by one and are located below the workbench 5; wherein each liquid extraction tube 31 is provided with a connecting base 35 fixed thereon, and the two ends of the connecting base 35 are rotatably connected to the return rod 33 through a second connecting rod 36; wherein the second connecting rod 36 is a rotating connecting rod, one end of the second connecting rod 36 is sleeved on the return rod 33, and the second connecting rod 36 is fixedly connected to the return rod 33; the other end of the second connecting rod 36 is rotatably connected to the connecting base 35; when in use, the liquid extraction tube 31 is connected to the multi-way recovery tube 37, and the multi-way recovery tube 37 is connected to an external recovery device.

[0113] like Figure 3 As shown, the reciprocating rod 33 is sleeved on the workbench 5, and the reciprocating rod 33 slides in the sliding groove of the workbench 5; wherein, a holding block is provided on the reciprocating rod 33;

[0114] The limiting ring 32 is located on the workbench 5 and is rotatably connected to the workbench 5 ; wherein the limiting ring 32 is rotatably connected to the reciprocating rod 33 via a first connecting rod 34 .

[0115] In practical applications, a second return spring 38 is sleeved on the outer side of the liquid extraction tube 31 , so that after the liquid is extracted, the liquid extraction tube 31 returns to the initial position under the action of the second return spring 38 .

[0116] The working principle of the liquid extraction mechanism 3 is as follows: after the operator holds the holding block tightly, he pulls the reciprocating rod 33 to the outside of the workbench 5. At this time, the reciprocating rod 33 drives the connecting base 35 to move upward through the second connecting rod 36. At this time, the liquid extraction tube 31 arranged on the connecting base 35 moves upward, and the liquid extraction tube 31 passes through the through hole 37 of the workbench and is inserted into the leather plug 63; then the liquid in the storage tank 6 flows out from the liquid extraction tube 31 to the multi-way recovery tube 37, and then the liquid is recovered to the external recovery device.

[0117] After the extraction is completed, the operator holds the flip handle 75 and then rotates the rotating rod 71 to make the fixed block 73 disengage from the limiting groove 74. At this time, the storage tank 6 rotates 180° in the opposite direction and returns to the initial position, so that the subsequent anti-corrosion mechanism 4 can inject the preservative into the storage tank 2.

[0118] like Figures 17 to 19 As shown, the anti-corrosion mechanism 4 includes a first clamping plate 41 , a second clamping plate 42 , a second driving unit 43 , an injection head 44 and a connecting block 45 .

[0119] Specifically, the first clamping plate 41 and the second clamping plate 42 are arranged in parallel, and the first clamping plate 41 and the second clamping plate 42 are fixedly connected by a connecting block 45. The outer side of the connecting block 45 is fixedly connected to the push rod 8; it should be noted that the embodiment of the present invention does not limit the fixed connection method of the connecting block 45 and the push rod 8, and for example, the connecting block 45 and the push rod 8 are connected by bolts.

[0120] A side of the first clamping plate 41 away from the second clamping plate 42 is fixedly connected to the push rod 48 .

[0121] The second driving unit 43 and the injection head 44 are disposed between the first clamping plate 41 and the second clamping plate 42 .

[0122] In actual use, the antiseptic mechanism 4 includes a plurality of injection heads 44, which correspond one to one with the storage tank 6. Specifically, an injection tube 44b is provided inside the injection head 44; the upper end of the injection tube 44b passes through a rack 44a provided at the upper end of the injection head 44 and is connected to the antiseptic containing device, and the lower end of the injection tube 44b passes through the injection head 44 so as to be inserted into the leather plug 63 so as to inject the antiseptic into the storage tank 6.

[0123] The rack 44a and the injection head 44 are integrally connected.

[0124] The end of the rack 44 a is connected to the first return spring 46 , and one end of the first return spring 46 away from the rack 44 a is connected to a limiting groove 74 provided on the first clamping plate 41 .

[0125] When in use, the rack 44 a is driven by the second driving unit 43 to move linearly in the limiting groove 74 .

[0126] The second driving unit 43 includes a worm 43a and a worm wheel 43b; the worm wheel 43b includes an inner gear 43b-1 and an outer gear 43b-2; wherein the inner gear 43b-1 and the outer gear 43b-2 are arranged in arc shape and parallel, and the inner gear 43b-1 and the outer gear 43b-2 are integrally connected.

[0127] Specifically, the worm 43 a is disposed between the first clamping plate 41 and the second clamping plate 42 , and both ends of the worm 43 a are rotatably connected to the connecting block 45 , respectively; wherein one end of the worm 43 a is connected to the rotating handle 49 .

[0128] The external gear 43b-2 is gear-engaged and connected with the worm 43a;

[0129] The internal gear 43b-1 is gear-meshed with the rack 44a.

[0130] The working principle of the anti-corrosion mechanism 4 is as follows: the operator holds the push rod 8 to move the anti-corrosion mechanism 4 toward the top of the storage tank 6 until the injection head 44 is located above the leather plug 63 of the storage tank 6; then the handle 48 is turned to drive the worm 43a to rotate, and then the worm 43a drives the outer gear 43b-2 to rotate, and the inner gear 43b-1 rotates coaxially with the outer gear 43b-2, and then the inner gear 43b-1 drives the rack 44a to move linearly downward, thereby moving the injection head 44 located at the lower end of the rack 44a to the side close to the leather plug 63 until the injection tube on the injection head 44 is inserted into the leather plug 63, so as to inject the preservative into the storage tank 6.

[0131] After the injection is completed, the rack 44 a and the injection head 44 disposed at the lower end of the rack 44 a return to the initial position under the action of the first return spring 46 .

[0132] Example 2

[0133] Based on Example 1, different from Example 1, the storage tank 6 and the shell 11b provided in the embodiment of the present invention are made of transparent hard material, for example, the storage tank 6 and the shell 11b are made of tempered glass. In this way, when in use, the operator can more accurately adjust the position of the outflow baffle 62.

[0134] Application examples:

[0139] 4) starting the first motor, driving the threaded rod 13 to rotate through the first motor, and under the action of the threaded limit of the threaded rod 13, driving the magnetic ring 12 to move linearly, and then under the action of magnetic attraction, the outflow baffle 62 moves with the movement of the magnetic ring 12, thereby adjusting the visceral specimen accommodation space;

[0140] 5) Install the leather plug 36 to complete the placement and fixation of the visceral specimen;

[0141] Step 2: The operator holds the flip handle 75 and rotates the rotating rod 71. After the rotating rod 71 rotates 180°, the fixed block 73 at the end of the rotating rod 71 is connected with the fixed rod 72 arranged on the workbench to fix the visceral specimen fixing mechanism 1. At this time, the storage tank 6 is inverted to perform centrifugal operation on the visceral specimen in the storage tank 6.

[0142] Step 3: Start the second motor, the second motor drives the rotating shaft 22 to rotate, and then the rotating shaft 22 drives the storage tank 6 to rotate through the rotating belt 21, that is, the centrifugal operation is performed;

[0143] Step 4: After the centrifugal operation is completed, the operator manually pulls the reciprocating rod 33 toward the outside of the workbench 5, and the reciprocating rod 33 drives the connecting base 35 to move upward through the second connecting rod 36 until the liquid extraction tube 31 provided on the connecting base 35 passes through the through hole of the workbench 5 and is inserted into the leather plug 63, so that the liquid is drained from the storage tank 6 to the external recovery device;

[0144] Step 5: After the liquid recovery is completed, the operator holds the flip handle 75 and then rotates the rotating rod 71 in the opposite direction to return the storage tank 6 to the initial position so as to inject the preservative into the storage tank 6;

[0145] Step 6: The operator holds the push rod 8 to push the anti-corrosion mechanism 4 to the top of the storage tank 6;

[0146] Step seven: The operator holds the rotating handle 48 to rotate the worm 43a, and then the worm 43a drives the worm wheel 43b to rotate, and then the internal gear 43b-1 in the worm wheel 43b drives the rack 44a to move linearly downward until the injection tube on the injection head 44 is inserted into the leather plug 63 of the storage tank 6 to achieve the injection of the preservative. At this time, the preservation of the visceral specimen is completed.
