Description

A convenient and adjustable storage device for human anatomical specimens Technical Field

[0001] This invention relates to the field of human anatomy technology, specifically to a human anatomical specimen storage device that is easy to adjust and view. Background Technology

[0002] Human anatomy is a morphological science, highly intuitive, and characterized by numerous terms and descriptions. Therefore, during the learning process, it is essential to make full use of various specimens, models, pictures, and other visual aids, observing, touching, thinking, and memorizing extensively to deepen understanding and mastery of normal human anatomy. Currently, the specimens used in human anatomy are fresh specimens donated by volunteers. They are perfused and fixed in a formalin solution at a specific ratio through the carotid or femoral artery. After processing, the specimens need to be stored and preserved for future regional anatomical experiments, systemic anatomical specimen preparation, and scientific research. However, most existing storage devices are cadaver pools, which are not convenient for viewing the specimens inside. When viewing is required, the specimens must be removed. Because the formalin solution is inside the device, the solution may splash, wasting teaching resources, or the solution may evaporate over time, causing the specimens to become moldy and damaged.

[0003] Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use human anatomical specimen storage device that allows for easy adjustment and viewing without removing the specimen. This avoids the problems of solution splashing, which wastes teaching resources, or solution evaporation over time, which prevents the specimen from becoming moldy and damaged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a placement box, supporting legs, a placement platform, and a cover plate; supporting legs are fixed at the four corners of the outer bottom wall of the placement box; a placement platform is provided inside the placement box; and a cover plate is provided on the upper side of the placement box; it further comprises:

[0006] Connecting rods, there are four connecting rods, and they are respectively fixed to the four corners of the upper surface of the placement plate, and the upper end of the connecting rods is fixed to the lower surface of the cover plate;

[0007] The mounting plate is located on the upper side of the cover plate, and a transparent cover is fixed on the lower side of the mounting plate. The transparent cover is fitted over the outside of the placement box, and the bottom wall of the transparent cover abuts against the convex edge of the bottom wall of the placement box.

[0008] The push screws consist of four screws, which are symmetrically arranged in pairs on the left and right side walls of the placement box. The upper end of the push screw is fixed to the lower surface of the cover plate. Each push screw is fitted with an internal threaded tube, which is screwed into the placement box through a bearing. The four internal threaded tubes are connected to each other through a synchronous pulley transmission assembly.

[0009] The drive motor is embedded and fixed in the bottom wall of the placement box, and the output shaft of the drive motor is connected to one of the internal threaded tubes through a synchronous pulley transmission assembly.

[0010] A connecting mechanism is provided inside the mounting plate and is connected to the top wall of the cover plate;

[0011] A limiting mechanism is provided inside the cover plate and is suspended on the upper side inside the placement box.

[0012] The above technical solution involves first loosening the connecting mechanism, then using the mounting plate to move the transparent cover upwards out of the placement box. Next, the drive motor is started, and through the synchronous pulley transmission assembly, it drives the connected internally threaded tube to rotate. This internally threaded tube, through the synchronous pulley transmission assembly, drives three other internally threaded tubes to rotate. These four internally threaded tubes, through their respective internal push screws, move the cover plate upwards. The cover plate, through the connecting rod, moves the placement plate upwards until it is located on the upper side inside the placement box. The human specimen is then placed on the placement plate, formalin is poured into the placement box, and the drive motor, internally threaded tubes, and push screws then move the cover plate downwards. The cover plate moves downwards via a connecting rod, allowing the human specimen to be stored in the placement box. A transparent cover is then placed over the placement box and connected via a connecting mechanism, linking the mounting plate on the transparent cover to the cover plate for positioning. A limiting mechanism then restricts the specimen's position. When viewing is required, the drive motor is activated, driving the cover plate upwards via an internal threaded tube and a push screw. The cover plate then moves the mounting plate and transparent cover upwards. Once the placement plate is positioned at the top inside the placement box, the transparent cover is located outside the human specimen, preventing formalin spillage without obstructing viewing.

[0013] As a further improvement of the present invention, the connecting mechanism includes:

[0014] The connecting plates are two in number and are fixed symmetrically on the upper surface of the cover plate. The connecting plates are inserted into the slots on the lower surface of the mounting plate. The connecting plates are inserted into the connecting grooves on the side wall of the connecting plate adjacent to the center of the cover plate.

[0015] The connecting rack consists of two racks, which are fixed one-to-one on one side wall of the insert plates on both sides. The connecting racks are movably disposed in the mounting plate. A linkage gear is meshed between the two connecting racks. The linkage gear is screwed into the mounting plate through a shaft.

[0016] Two reset springs are provided, each embedded and fixed in the side wall of the connecting strip away from the insert plate, and the other end of the reset spring is fixedly connected to the inner wall of the mounting plate.

[0017] The rotating handle is embedded in a circular groove on the surface of the mounting plate, and the shaft on the rotating handle is inserted into the mounting plate and is fixedly connected to the linkage gear.

[0018] With the above technical solution, when it is necessary to place a human specimen, hold the rotating handle, rotate the handle to drive the linkage gear to rotate, the linkage gear to drive the connecting racks on both sides to move, the connecting racks to drive the corresponding insert plate to move, so that the insert plate is moved out of the connecting plate, thereby separating the mounting plate from the cover plate.

[0019] As a further improvement of the present invention, the limiting mechanism includes:

[0020] A limiting plate is suspended on the upper side inside the placement box. A fixing plate is provided on the upper side of the limiting plate, and the four corners of the fixing plate are movably sleeved on the connecting rod.

[0021] The rotating rods consist of four rods, each of which is connected in pairs to the left and right sides of the strip grooves symmetrically arranged on the upper surface of the fixed plate via shafts.

[0022] The telescopic connecting rod consists of two rods, which are symmetrically arranged in the strip groove on the fixed plate. The two support rods on the lower side of the telescopic connecting rod are respectively screwed to the upper end of the rotating rod through the shaft. The upper end of the telescopic connecting rod is embedded in the rectangular groove on the lower surface of the cover plate.

[0023] Two bidirectional lead screws are provided, which are symmetrically arranged in the cover plate by bearings. The two bidirectional lead screws are connected by a synchronous pulley transmission assembly. Both ends of the bidirectional lead screws are threaded with sliding blocks. The sliding blocks are screwed to two support rods on the upper side of the telescopic connecting rod through hinge seats.

[0024] A limit motor is embedded and fixed inside the cover plate, and the output shaft of the limit motor is connected to one end of one of the bidirectional lead screws.

[0025] The above technical solution involves activating a limit motor, which drives a connected bidirectional lead screw to rotate. This bidirectional lead screw, through a synchronous wheel transmission assembly, drives another bidirectional lead screw to rotate. The two bidirectional lead screws, through sliding blocks, drive the upper support rod of the telescopic connecting rod to rotate, thereby causing the lower end of the telescopic connecting rod to rotate the rotating rod. During the rotation of the telescopic connecting rod and the rotating rod, the fixed plate can move up and down, and the fixed plate drives the limit plate to move up and down until the limit plate touches the top of the human specimen, thus achieving the limiting effect.

[0026] As a further improvement of the present invention, a rotating disk is screwed onto the upper surface of the placement plate via a shaft, and a rotary motor is fixed to the bottom end of the rotating disk. The rotary motor is embedded in the placement plate, and a disc is fixed to the upper side of the limiting plate. The upper surface of the disc is screwed onto the lower surface of the fixing plate via a shaft.

[0027] With the above technical solution, when it is necessary to examine a human specimen, a rotary motor can be started, which drives the rotating disk to rotate, and the rotating disk drives the human specimen to rotate. At the same time, the limiting plate on the human specimen can rotate under the fixed plate through the disk, thereby facilitating the examination of the human specimen from different directions.

[0028] As a further improvement of the present invention, an annular slide rail is fixed on one side wall of both the rotating disk and the disc, and the annular slide rail is slidably disposed in the annular groove on the side wall of the fixed placement plate and the fixed plate, respectively; this can increase the stability of the rotating disk and the disc when rotating.

[0029] As a further improvement of the present invention, limiting blocks are fixed on both the left and right inner walls of the placement box. The limiting blocks are set in the embedding grooves on both sides of the lower surface of the fixing plate, and the limiting blocks are inserted into the grooves on the left and right side walls of the placement plate.

[0030] The above technical solution allows the placement plate to be stopped by a limiting block after it moves upward, preventing the placement plate from moving out of the placement box and causing damage to the human specimen.

[0031] As a further improvement of the present invention, a sealing ring is provided on the upper side of the outer peripheral wall of the placement box, and the outer peripheral wall of the sealing ring is arranged to abut against the inner wall of the transparent cover.

[0032] The above technical solution can prevent formalin from leaking out from the gap between the transparent shield and the placement box when examining human specimens.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. The drive motor, push screw and internal thread tube can move the placement plate and cover plate up and down, so that the specimen can be viewed without taking it out. This will prevent the solution from splashing and wasting teaching resources or the solution from evaporating over time and causing the specimen to become moldy and damaged.

[0035] 2. A transparent cover is provided on the outside of the placement box to protect the specimen without affecting the viewing of the specimen. At the same time, the mounting plate on the transparent cover can be connected to the cover plate through the connecting mechanism, so that the transparent cover can be easily removed when the specimen needs to be placed in and taken out.

[0036] 3. A limiting mechanism is provided on the underside of the cover plate, which can limit the specimen and improve the stability of the specimen. Attached Figure Description

[0045] Example 1:

[0046] As shown in Figures 1-6, this embodiment includes a placement box 1, supporting legs 2, a placement plate 3, and a cover plate 4. Supporting legs 2 are welded and fixed to the four corners of the outer bottom wall of the placement box 1. The placement plate 3 is installed inside the placement box 1, and the cover plate 4 is installed on the upper side of the placement box 1. It also includes:

[0047] Connecting rod 5, there are four connecting rods 5, and they are respectively welded and fixed to the four corners of the upper surface of the placement plate 3, and the upper end of the connecting rod 5 is welded and fixed to the lower surface of the cover plate 4.

[0048] Mounting plate 6 is disposed on the upper side of cover plate 4. A transparent cover 7 is glued and fixed to the lower side of mounting plate 6. The transparent cover 7 is sleeved on the outside of the placement box 1. The bottom wall of the transparent cover 7 abuts against the convex edge of the bottom wall of the placement box 1. A sealing ring 16 is sleeved and glued on the upper side of the outer peripheral wall of the placement box 1. The outer peripheral wall of the sealing ring 16 abuts against the inner wall of the transparent cover 7. This can prevent formalin from flowing out from the gap between the transparent cover 7 and the placement box 1 when examining human specimens.

[0049] There are four push screws 8, which are symmetrically arranged in pairs on the left and right side walls of the placement box 1. The upper end of the push screw 8 is welded and fixed to the lower surface of the cover plate 4. The outer side of each push screw 8 is fitted with an internal threaded tube 9. The internal threaded tube 9 is screwed into the placement box 1 through a bearing. The four internal threaded tubes 9 are connected to each other through a synchronous wheel transmission assembly.

[0050] The drive motor 10 is embedded and fixed in the bottom wall of the placement box 1. The output shaft of the drive motor 10 is connected to the internal threaded tube 9 on the left front side through a synchronous pulley transmission assembly.

[0051] The connecting mechanism 11 is disposed inside the mounting plate 6 and is connected to the top wall of the cover plate 4.

[0052] The limiting mechanism 12 is disposed inside the cover plate 4 and suspended on the upper side inside the placement box 1.

[0054] Referring to Figures 1-2 and 4, based on Embodiment 1, the connecting mechanism 11 includes:

[0055] Connecting plate 11-1, there are two connecting plates 11-1, and they are symmetrically welded and fixed on the upper surface of cover plate 4. Connecting plate 11-1 is inserted into the slot on the lower surface of mounting plate 6. Inserting plate 11-2 is inserted into the connecting groove on the side wall of connecting plate 11-1 adjacent to the center of cover plate 4.

[0056] Two connecting racks 11-3 are provided, and they are welded and fixed to one side wall of the insert plates 11-2 on both sides. The connecting racks 11-3 are movably disposed in the mounting plate 6. A linkage gear 11-4 is meshed between the two connecting racks 11-3. The linkage gear 11-4 is screwed into the mounting plate 6 through a shaft.

[0059] Example 3:

[0060] Referring to Figures 2 and 5-6, based on Embodiment 1, the limiting mechanism 12 includes:

[0061] A limiting plate 12-1 is suspended on the upper side inside the placement box 1. A fixing plate 12-2 is provided on the upper side of the limiting plate 12-1, and the four corners of the fixing plate 12-2 are movably sleeved on the connecting rod 5. A rotating disk 13 is screwed to the upper surface of the placement plate 3 via a shaft. A rotary motor 14 is fixed to the bottom end of the rotating disk 13 and is embedded in the placement plate 3. A disc 15 is welded and fixed to the upper side of the limiting plate 12-1. The upper surface of the disc 15 is screwed to the lower surface of the fixing plate 12-2 via a shaft. When it is necessary to examine the human specimen, the rotary motor 14 can be started. The rotary motor 14 drives the rotating disk 13 to rotate, and the rotating disk 13 drives the human specimen to rotate. At the same time, the limiting plate 12-1 on the human specimen can rotate on the lower side of the fixing plate 12-2 via the disc 15, thereby facilitating the examination of the human specimen from different directions.

[0062] Annular slide rails 17 are welded and fixed to one side wall of both the rotating disk 13 and the disc 15. The annular slide rails 17 are slidably arranged in the annular grooves on the side wall of the fixed placement plate 3 and the fixed plate 12-2, respectively. This can increase the stability of the rotating disk 13 and the disc 15 when rotating. Limiting blocks 18 are fixed on the left and right inner walls of the placement box 1. The limiting blocks 18 are set in the embedded grooves on both sides of the lower surface of the fixed plate 12-2. The limiting blocks 18 are inserted into the grooves on the left and right side walls of the placement plate 3. After the placement plate 3 moves upward, the limiting blocks 18 can limit the placement plate 3 to prevent the placement plate 3 from moving out of the placement box 1 and causing damage to the human specimen.

[0063] Rotating rod 12-3, there are four rotating rods 12-3, and each pair of them is screwed to the left and right sides of the strip groove symmetrically arranged on the upper surface of the fixed plate 12-2 through shafts;

[0064] Telescopic connecting rod 12-4, there are two telescopic connecting rods 12-4, and they are symmetrically arranged in the strip groove on the fixed plate 12-2. The two support rods on the lower side of the telescopic connecting rod 12-4 are respectively screwed to the upper end of the rotating rod 12-3 through the shaft. The upper end of the telescopic connecting rod 12-4 is embedded in the rectangular groove on the lower surface of the cover plate 4.

[0065] Two bidirectional lead screws 12-5 are symmetrically arranged in the cover plate 4 and screwed together by bearings. The two bidirectional lead screws 12-5 are connected by a synchronous pulley transmission assembly. Both ends of the bidirectional lead screw 12-5 are threaded with sliding blocks 12-6. The sliding blocks 12-6 are screwed to two support rods on the upper side of the telescopic connecting rod 12-4 through hinge seats.

[0066] The limit motor 12-7 is embedded and fixed inside the cover plate 4, and the output shaft of the limit motor 12-7 is connected to the left end of the bidirectional lead screw 12-5 on the front side.

[0067] When using this invention, when placing a human specimen, hold the rotating handle 11-6. Rotating the handle 11-6 drives the linkage gear 11-4 to rotate. The linkage gear 11-4 drives the connecting racks 11-3 on both sides to move. The connecting racks 11-3 drive the corresponding insert plates 11-2 to move, so that the insert plates 11-2 move from the connecting plate 11-1. The mounting plate 6 is moved outward, allowing it to separate from the cover plate 4. The mounting plate 6 then moves the transparent cover 7 upward out of the placement box 1. The drive motor 10 is then activated, driving the connected internal threaded tube 9 to rotate via a synchronous pulley transmission assembly. This internal threaded tube 9, in turn, drives three other internal threaded tubes 9 to rotate via the same assembly. These four internal threaded tubes 9, through their respective internal push screws 8, move the cover plate 4 upward. The cover plate 4, via a connecting rod 5, moves the placement plate 3 upward until it is located on the upper side inside the placement box 1. The human specimen is then placed on the placement plate 3, and formalin is poured into the placement box 1. The drive motor 10, internal threaded tubes 9, and push screws 8 then move the cover plate 4 downward. The cover plate 4, via the connecting rod 5, moves the placement plate 3 downward, thus storing the human specimen inside the placement box 1. Finally, the transparent cover 7 is placed over the placement box 1 and connected via a connecting mechanism 11, connecting the mounting plate 6 on the transparent cover 7 to the cover plate 4 for positioning. The limit switch is then activated. Machine 12-7, limit motor 12-7 drives the connected bidirectional lead screw 12-5 to rotate. This bidirectional lead screw 12-5 drives another bidirectional lead screw 12-5 to rotate through a synchronous pulley transmission assembly. The two bidirectional lead screws 12-5 respectively drive the support rod at the upper end of the telescopic connecting rod 12-4 to rotate through the sliding block 12-6, thereby causing the lower end of the telescopic connecting rod 12-4 to drive the rotating rod 12-3 to rotate. During the rotation of the telescopic connecting rod 12-4 and the rotating rod 12-3, the fixed plate 12-2 can be moved up and down, fixing... Plate 12-2 drives the limiting plate 12-1 to move up and down until the limiting plate 12-1 touches the top of the human specimen, thereby achieving the limiting effect. When it is necessary to view, the drive motor 10 is directly started, and the cover plate 4 is driven to move upward through the internal threaded tube 9 and the push screw 8. The cover plate 4 drives the mounting plate 6 and the transparent cover 7 to move upward. When the placement plate 3 moves to the upper side inside the placement box 1, the transparent cover 7 is located outside the human specimen, thereby preventing formalin from splashing out without affecting the viewing.

[0068] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0069] 1. The drive motor 10, push screw 8 and internal thread tube 9 can drive the placement plate 3 and cover plate 4 to move up and down, so that the specimen can be viewed without taking it out, thus preventing the solution from splashing or the specimen from being damaged.

[0070] 2. A transparent cover 7 is provided on the outside of the placement box 1. The specimen can be protected by the transparent cover 7 without affecting the viewing of the specimen. At the same time, the mounting plate 6 on the transparent cover 7 can be connected to the cover plate 4 through the connecting mechanism 11. When it is necessary to put in and take out the specimen, the transparent cover 7 can be easily removed.

[0071] 3. A limiting mechanism 12 is provided on the lower side of the cover plate 4, which can limit the specimen and improve the stability of the specimen.

[0072] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
