Description

Technical Field

[0001] The invention relates to an intelligent double-layer box-type dissecting table capable of interchanging positions, belonging to the technical field of medical dissection. Background Art

[0002] During the dissection of corpses or body parts, a traditional tray-type dissection table is generally used. Its structure is a fixed single-layer tray table. Not only can the height of this type of dissection table not be adjusted during operation and has certain requirements on the height of the operator, but also the experimental subject will be exposed to the air for too long, which will cause irreversible damage. The volatilization of formalin in the experimental subject will also affect the health of the operator.

[0003] For example, the dissection table with an exhaust mechanism disclosed in CN2549908Y, while equipped with an exhaust mechanism, is located at the bottom, resulting in limited exhaust effectiveness and failing to address the problem of residual stains on the dissection table. This inevitably leads to poor cleaning results and requires manual cleaning of the dissection table to prevent contamination of the next subject. Furthermore, although this solution is equipped with a pulley system for lifting and lowering, when two subjects need to be dissected consecutively, transferring the original subject and replacing it with a new one is cumbersome, resulting in transfer defects. This defect also exists in CN205251749U and CN113397755A. Using only a single transfer device is not conducive to switching and transferring subjects after dissection. Furthermore, during the transfer process, these devices require manual cleaning of the table, which also affects work efficiency, causing great inconvenience to the operator and potentially exposing the subject to contamination from the external environment or human contact during the transfer or manual cleaning process. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an intelligent double-layer box-type dissection table that can interchange positions, comprising a control module, a power module, and two box-type dissection tables. The control module includes a controller and a motor, and the power module includes a rotating shaft, a rotating frame, and a hydraulic cylinder. Both sides of each box-type dissection table are connected to a box shaft, and the box shaft can be any shaft member connecting the box body.

[0005] The motor is connected to and controls the rotating shaft, and the rotating shaft is connected to the rotating frame via a crossbar. The rotating frame is square and provided with a guide rail, and the box shaft is matched with the guide rail via a bearing.

[0006] It should be understood that the box-type dissecting table is a box for placing experimental subjects. The experimental subjects can be complete human corpses or incomplete body parts, such as corpses or body parts retrieved from a formalin pool. The experimental subjects should be placed horizontally in the box-type dissecting table. For example, a human corpse can be placed on the dissecting table in a horizontal position similar to a human body, such as lying flat, lying on its side, or lying down. The bottom of the box should be facing the ground and in a horizontal position.

[0007] The “horizontal” refers to a state in an arbitrary plane parallel to the horizon relative to the ground, and the “vertical” refers to a state in an arbitrary plane perpendicular to the horizon relative to the ground.

[0008] When the motor is started to control the rotation of the rotating shaft, the rotating shaft will drive the rotating frame to rotate. The rotating frame will drive the two box-type dissection tables to rotate in the vertical plane with the rotating shaft as the rotating axis through the box shaft. Because the box shaft is set on the guide rail by bearings, the box-type dissection table always remains in a horizontal state under the action of gravity during the rotation process (that is, the bottom of the box-type dissection table and the experimental subject are both in a horizontal state), and the experimental subject will not flip (out of the horizontal state) during the rotation process;

[0009] Preferably, the box-type dissecting table is a rectangular box, and one side of the box-type dissecting table can be any side wall of the rectangular box. Since the box axis cooperates with the guide rail through bearings, under the action of gravity, the upper bottom surface and the lower bottom surface of the rectangular box and the experimental body will always remain horizontal during the rotation process.

[0010] In the initial state, the two box-type dissecting tables are vertically distributed up and down (that is, the box axes of the two box-type dissecting tables are parallel and in the same vertical plane); when the rotation axis rotates 180 degrees, the two box-type dissecting tables exchange their vertical up and down positions.

[0011] The box shaft is also equipped with a driving device with a self-locking function, which can push the box shaft to reciprocate horizontally on the guide rail and lock the position of the box shaft in the guide rail; the controller is connected to and controls the driving device and the motor.

[0012] It should be understood that when the box axis moves horizontally in a direction away from the rotation axis, the rotation radius of the two box-type dissecting tables will increase, making it easier for the operator to reach out and touch the box-type dissecting tables; conversely, when the box axis moves horizontally in a direction close to the rotation axis, the rotation radius of the two box-type dissecting tables will decrease, making it easier to lower the height of the box-type dissecting tables when the two box-type dissecting tables are vertically distributed up and down, which is suitable for operation by short operators.

[0013] Preferably, the rotating shaft is also provided with a self-locking device, which can lock the two box-type dissecting tables at any position on the circumference during the rotation process.

[0014] In one embodiment of the present invention, the driving device is a hydraulic driving device or an electric driving device; preferably, the driving device can be a hydraulic cylinder, including a cylinder slider, a cylinder and a cylinder guide rod, the cylinder slider is installed on the cylinder guide rod, and the cylinder slider is connected to and drives the box shaft.

[0015] Furthermore, in one embodiment of the present invention, the box-type dissecting table includes a box body, a box cover, a pulley group, a movable tray, a fixed tray, a sewage outlet, and a fresh air module, the pulley group includes a wire-taking pulley, a first fixed pulley and a second fixed pulley, a wire-taking pulley is installed at the bottom of the box body, and the first fixed pulley and the second fixed pulley are installed on both side walls of the box body in sequence from bottom to top, and a traction rope is wound around the wire-taking pulley, and the two ends of the traction rope are respectively directed toward the two side walls of the box body and pass through the first fixed pulley and the second fixed pulley in sequence, and the traction rope is connected to the movable tray after passing through the second fixed pulley and hangs the movable tray inside the box body, and the movable tray can be raised and lowered inside the box body by releasing or retracting the traction rope by the wire-taking pulley;

[0016] It should be understood that the take-up pulley refers to a fixed pulley used for winding several turns of traction rope, and the "first" and "second" are only used to distinguish the two fixed pulleys located at different heights on the side walls of the box and have no other meanings; the two side walls of the box refer to the two opposite side walls of the box. In the present invention, the bottom of the box should face the ground, and the direction of the bottom of the box relative to the ground is "up", and the direction of the ground relative to the bottom of the box is "up".

[0017] The fresh air module is an air outlet with a vacuum pump and is installed on the side wall of the box. The fresh air module can extract the toxic and harmful gases volatilized by the experimental body, making the cleaning rate reach 95%, avoiding the harm of harmful gases to the operators;

[0018] The box cover is provided at the upper opening of the box body, and the box cover is provided with a plurality of spray heads facing the bottom of the box body in the direction of the box cover facing the interior of the box body, and the spray heads can spray cleaning solvent; the fixed tray is located at a height position between the movable tray and the take-up pulley and is fixed to the inner side wall of the box body, and a sewage outlet is provided at the same height position of the side wall of the box body and the fixed tray; the spray heads are used to spray the cleaning solvent inside the box to clean, and the cleaning solvent after spraying is collected at the bottom of the box and flows out from the sewage outlet.

[0019] It should be understood that the movable tray is located above the fixed tray in the vertical direction, and the surface area of the fixed tray should be larger than the surface area of the movable tray; preferably, the edge of the movable tray is provided with a mesh, and the edge of the fixed tray is connected to the drain outlet by a hose. Such a setting allows the cleaning solvent to flow from the edge of the movable tray to the fixed tray, and then flow out of the drain outlet through the hose.

[0020] The box body is further provided with a cylinder near the box cover, and the cylinder can control the opening and closing of the box cover; the controller is connected to and can control the take-up pulley, the fresh air module, and the sprinkler head.

[0021] Preferably, the traction rope is a steel wire rope; the second fixed pulley is installed at the uppermost part of the side wall of the box.

[0022] Preferably, the take-up pulley is provided with a self-locking device, which can enable the tray to hover within a certain height range within the box.

[0023] Preferably, the controller is a PLC controller; the controller is also provided with a display screen and control buttons. Preferably, a Siemens SR10CPU and an analog module AM06 can be selected.

[0024] Preferably, the box body has a height of 350 mm and a width of 800 mm; the tray can be raised or lowered or hovered within a height range of 10 mm to 150 mm from the bottom of the box body.

[0027] 2. The present invention configures the dissection table into an independent box-type structure, and sets a pulley group and a fresh air module inside, which can not only further adapt to the operator's adjustment of the tray height to facilitate dissection, but also actively discharge harmful gases from the box, reducing safety hazards.

DETAILED DESCRIPTION

[0038] Example 1

[0039] like Figure 1-Figure 3 As shown, the present invention provides an intelligent double-layer box-type dissection table that can interchange positions, including a control module 1, a power module 2, and two box-type dissection tables 3. The control module 1 includes a controller 1-4 and a motor 1-3. The power module 2 includes a rotating shaft 2-2, a rotating frame 2-4, and a hydraulic cylinder 2-1. Each of the box-type dissection tables 3 is connected to a box shaft 3-1 on both sides.

[0040] The motor 1-3 is connected to and controls the rotating shaft 2-2. The rotating shaft 2-2 is connected to the rotating frame 2-4 via a cross bar 2-3. The rotating frame 2-4 is square and provided with a guide rail. The box shaft 3-1 is matched with the guide rail via a bearing.

[0041] When the motor 1-3 is started to control the rotation of the rotating shaft 2-2, the rotating shaft 2-2 will drive the rotating frame 2-4 to rotate, and the rotating frame 2-4 will drive the two box-type dissection tables 3 to rotate in a vertical plane with the rotating shaft 2-2 as the rotating axis through the box shaft 3-1. Since the box shaft 3-1 is set on the guide rail by a bearing, the box-type dissection table 3 always remains in a horizontal state under the action of gravity during the rotation process (that is, the bottom of the box-type dissection table 3 and the experimental subject are both in a horizontal state), and the experimental subject will not flip over (out of the horizontal state) during the rotation.

[0042] In the initial state, the two box-type dissecting tables 3 are vertically arranged up and down; after rotating 180 degrees, the two box-type dissecting tables exchange their vertically arranged up and down positions.

[0043] The box shaft 3-1 is also equipped with a driving device with a self-locking function, which is a hydraulic cylinder 2-1, including a cylinder slider 2-1-1, a cylinder 2-1-3 and a cylinder guide rod 2-1-2. The cylinder slider 2-1-1 is installed on the cylinder guide rod 2-1-2. The cylinder slider 2-1-1 is connected to and drives the box shaft 3-1 to reciprocate horizontally on the guide rail and can lock the position of the box shaft 3-1 in the guide rail; the controller 1-4 is connected to and controls the hydraulic cylinder 2-1 and the motor 1-3.

[0044] The rotating shaft 3 - 1 is also provided with a self-locking device, which can lock the two box-type dissecting tables 3 at any position on the circumference during the rotation process.

[0045] like Figure 4 As shown, the box-type dissection table 3 includes a box body 3-2, a box cover 3-3, a pulley group, a movable tray 3-8, a fixed tray 3-9, a sewage outlet 3-10, and a fresh air module 3-11. The pulley group includes a take-up pulley 3-7, a first fixed pulley 3-5, and a second fixed pulley 3-6. The take-up pulley 3-7 is installed at the bottom of the box body 3-2, and the first fixed pulley 3-5 and the second fixed pulley 3-6 are installed on both side walls of the box body 3-2 in sequence from bottom to top. 3-7 is wound with a traction rope 3-12, and the two ends of the traction rope 3-12 are respectively directed towards the two side walls of the box body 3-2 and pass through the first fixed pulley 3-5 and the second fixed pulley 3-6 in sequence. After passing through the second fixed pulley 3-6, the traction rope 3-12 is connected to the movable pallet 3-8 and the movable pallet 3-8 is hung inside the box body 3-2. By releasing or retracting the traction rope through the take-up pulley 3-7, the movable pallet 3-8 can be raised or lowered or hovered inside the box body.

[0046] The fresh air module 3-11 is an air outlet with a vacuum pump and is installed on the side wall of the box 3-2. The fresh air module 3-11 can extract the toxic and harmful gases volatilized from the experimental body, making the cleaning rate reach 95%, avoiding the harm of harmful gases to the operators.

[0047] The box cover 3-3 is provided on the upper opening of the box body 3-2, and the box cover 3-3 is provided with a plurality of spray heads 3-13 facing the bottom of the box body 3-2 in the direction of the inside of the box body 3-2, and the spray heads 3-13 can spray cleaning solvent; the fixed tray 3-9 is located at a height position between the movable tray 3-8 and the take-up pulley 3-7 and is fixed to the inner side wall of the box body 3-2, and a sewage outlet 3-10 is provided at the same height position of the side wall of the box body 3-2 and the fixed tray 3-9; the spray heads 3-13 are used to spray the cleaning solvent inside the box body 3-2 to clean it, and the cleaning solvent after spraying is collected at the bottom of the box body 3-2 and flows out from the sewage outlet 3-10.

[0048] The edge of the movable tray 3-8 is provided with a mesh, and the edge of the fixed tray 3-9 is connected to the drain outlet 3-10 by a hose. Such an arrangement allows the cleaning solvent to flow from the edge of the movable tray 3-8 to the fixed tray 3-9, and then flow out of the drain outlet 3-10 through the hose.

[0049] The box body 3-2 is also provided with a cylinder 3-4 near the box cover 3-3, and the cylinder 3-4 can control the opening and closing of the box cover 3-3; the controller 1-4 is connected to and can control the take-up pulley 3-7, the fresh air module 3-11, and the sprinkler head 3-13.

[0050] The traction rope 3-12 is a steel wire rope; the second fixed pulley 3-6 is installed on the uppermost part of the side wall of the box body 3-2.

[0051] The take-up pulley 3-7 is provided with a self-locking device, which can enable the tray to hover within a certain height range in the box.

[0052] Preferably, the controller 1-4 is a PLC controller; the controller 1-4 is also provided with a display screen 1-1 and control buttons 1-2.

[0053] The box 3-2 has a height of 350 mm and a width of 800 mm; the distance between the two boxes 3-2 is 250 mm; the tray can be raised or lowered or hovered within a height range of 10 mm to 150 mm from the bottom of the box.

[0054] Example 2

[0055] When the operator is tall enough and able to operate the upper box-type dissection table 3 in the initial state, first adjust it to the initial state through the controller 1-4, that is, the two box-type dissection tables 3 are vertically distributed up and down; dissect the first experimental body on the upper box-type dissection table 3: open the box cover 3-3 through the cylinder 3-4 and place the experimental body on the movable tray 3-8, then control the pulley group through the controller 1-4 to adjust the movable tray 3-8 to a height suitable for the operator, and then dissect the first experimental body.

[0056] After the first experimental body is dissected, the fresh air module 3-10 can be opened to extract the harmful gases and formalin inside the box 3-2, and the sprinkler head 3-13 can be opened to clean the inside of the box 3-2.

[0057] like Figure 5 As shown, when it is necessary to continue dissecting the second experimental body, there is no need to transfer the first experimental body from the upper box-type dissecting table 3. It is only necessary to control the cylinder 3-4 to close the box cover 3-3 of the upper box-type dissecting table 3, and then control the hydraulic cylinder 2-1 to push the box shaft 3-1 and the box-type dissecting table 3 to translate in a direction away from the rotation axis 2-2 and self-lock, so that the rotation radius of the box-type dissecting table 3 increases; then start the motor 1-3 to make the rotation axis 2-2 rotate counterclockwise, and the two box-type dissecting tables 3 always remain horizontal during the rotation process;

[0058] After rotating 180 degrees, the motor 1-3 is stopped, and the hydraulic cylinder 2-1 is controlled to push the box shaft 3-1 and the box-type dissecting table 3 to move horizontally in the direction close to the rotating axis 2-2 to the upper and lower distribution positions on the same vertical plane and self-lock, thereby realizing the upper and lower interchange of the two boxes. During the whole process, the box-type dissecting table 3 always remains horizontal and the experimental object will not flip over.

[0059] Example 3

[0060] When the operator is short and cannot operate the upper box-type dissection table 3 in the initial state, the controller 1-4 can be used to adjust it to the initial state, that is, the two box-type dissection tables 3 are vertically distributed up and down; the first experimental subject on the lower box-type dissection table 3 is dissected, and then the operation of Example 2 is performed to switch to the second experimental subject.

[0061] The box-type dissection table 3 can also be rotated to a height position where it can be operated by adjusting the controller 1-4. For example, after rotating 125.5 degrees from the initial state, the rotation axis 3-1 is stopped and self-locked, and then the operation of Example 2 is performed to switch to the second experimental subject.

[0062] It should be understood that the user can adjust the rotation angle of the rotating shaft 3-1 and the height of the movable tray 3-8 according to his or her own situation.

[0063] Although the present invention has been disclosed above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
