Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a transport box for organ transplantation. Background Art

[0002] Organ transplantation is one of the major achievements of contemporary medicine, saving countless patients who were critically ill due to organ necrosis and disease. In organ transplantation surgery, there is often a certain distance between the organ donor and the organ recipient, which requires the transplanted organ to be transported over a long distance to reach the patient's hospital. During transportation, due to the particularity of the transplanted organ, it is not fixed in the transport box. Any bumps and vibrations will cause the organ to collide with the box wall, causing damage to the organ. Therefore, a device that can protect and reduce shock during the organ transplantation transportation process is needed. Summary of the invention

[0003] In view of this, the present invention discloses a transport box for organ transplantation, which aims to solve the problem that the transplanted organ may be damaged due to collision between the organ and the box wall caused by bumps and vibrations during transportation.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A transport box for organ transplantation comprises a box body and a box cover, wherein a lower arc plate is arranged in the box body, an upper arc plate is arranged in the box cover, and the lower arc plate and the upper arc plate are closed to form a spherical cavity; a suspended box for placing its organs is placed in the lower arc plate, a counterweight block is arranged at the bottom of the suspended box, and a first annular frame and a second annular frame with coaxial lines are sequentially sleeved on the circumference of the suspended box, a first rotating shaft is rotatably connected between the two sides of the suspended box and the first annular frame, a second rotating shaft is rotatably connected between the two sides of the first annular frame and the second annular frame, and the first rotating shaft and the second rotating shaft are perpendicular to each other; a plurality of telescopic rods are distributed in a circular array around the second annular frame, and magnetic balls adsorbed by the upper arc plate and the lower arc plate are arranged at the ends of the telescopic rods; cooling liquid is arranged between the box cover and the upper arc plate, and between the box body and the lower arc plate.

[0006] In this solution, since the suspended box is always in a suspended state under the action of the telescopic rod and the magnetic adsorption ball, when the transport box is subjected to a horizontal force, the suspended box drives the magnetic adsorption ball to slide through the first annular frame, the second annular frame and the telescopic rod, and uses the friction between the magnetic adsorption ball and the upper arc plate or the lower arc plate for energy dissipation and shock absorption; during this process, under the action of the counterweight block, the suspended box cooperates with the rotation between the first annular frame and the first rotating shaft and the rotation between the second annular frame and the second rotating shaft, so that the suspended box always maintains a horizontal state during the movement, reducing the influence of external vibration on the organ and the suspended box, avoiding the collision between the organ and the box wall, and preventing the organ from being damaged. In addition, when the transport box is subjected to an external force in the vertical direction, the suspended box moves vertically relative to the upper arc plate and the lower arc plate. During this process, by using the telescopic characteristics of the magnetic adsorption ball and the telescopic rod, the magnetic adsorption ball always maintains adsorption with the arc plate or the lower arc plate, synchronously performs friction energy dissipation, and cooperates with structures such as the first annular frame and the second annular frame to always maintain the vertical state of the suspended box.

[0007] Further, the telescopic rod includes a fixed sleeve fixedly connected to the second annular frame. A moving rod is coaxially and slidably connected in the fixed sleeve. The magnetic adsorption ball is fixed to one end of the moving rod. A hydraulic damper is fixed to the other end of the moving rod. The end of the hydraulic damper is fixed with a sliding seat. The width of the sliding seat is greater than the widths of the moving rod and the hydraulic damper; a plurality of sliding grooves are formed on both sides of the moving sleeve. The sliding grooves are all slidably connected with a limiting rod with an arc-shaped end. An elastic support member is arranged between the limiting rod and the sliding groove.

[0008] In this solution, when the suspended box moves and causes the telescopic rod to expand and contract, the moving rod drives the sliding seat to slide through the hydraulic damper. When the sliding seat abuts against one pair of limiting rods, the moving rod stretches or compresses the hydraulic damper. At this time, the hydraulic damper is used for energy dissipation to avoid the vibration caused by the expansion and contraction of the telescopic rod from being transmitted into the suspended box; when the hydraulic damper is stretched or compressed to a certain extent, the acting force of the sliding seat squeezing the limiting rod in this process continuously increases. At this time, the acting force received by the limiting rod is greater than the elastic force of the elastic support member, so that the limiting rod slides into the sliding groove, enabling the sliding seat to continue to move until it abuts against the next pair of limiting rods; during the sliding process of the sliding seat, the hydraulic damper resets itself; during the whole process, the hydraulic damper is used for energy dissipation in stages, effectively improving the energy dissipation range of the hydraulic damper within a short distance.

[0009] Further, a transmission shaft extending into the fixed sleeve is rotatably connected between adjacent fixed sleeves. The transmission shaft is rotatably connected to the fixed sleeve. Transmission gears coaxial with each other are fixed to both ends of the transmission shaft; mounting grooves parallel to the support rod are formed at both ends of the support rod. Tooth shapes meshing with the corresponding transmission gears are arranged on the upper end surfaces of the mounting grooves.

[0010] When the moving rod moves, the moving rod drives the transmission gear to rotate through the teeth on the installation groove, and drives the transmission gear in the adjacent fixed sleeve to rotate by using the transmission shaft, so that the adjacent moving rods move synchronously, and further all the moving rods move synchronously, evenly dissipating the received kinetic energy and reducing the impact on the suspended box.

[0011] Further, sealing plates are fixed between the box cover and the upper arc-shaped plate, and between the box body and the lower arc-shaped plate. A number of connecting holes are provided on the sealing plates in a one-to-one correspondence. Branch pipes are provided at the connecting holes, and valves are provided at the pipe orifices of the branch pipes; rubber layers are provided on the opposite end faces of the sealing plates; a refrigeration device is provided in the box cover, and a pump is provided at one of the branch pipes on the upper arc-shaped plate.

[0012] Further, a limiting block for preventing the sliding seat from sliding out is provided at the port of the fixed sleeve.

[0013] Further, buffer rubber layers are provided on both sides of the end of the sliding seat.

[0014] Other advantages, objectives and features of the present invention will be described in the subsequent description, and to some extent will be obvious to those skilled in the art, or those skilled in the art can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. Description of the Drawings

Detailed Embodiments

[0021] like Figures 1 to 4 As shown:

[0022] A transport box for organ transplantation comprises a box body 1 and a box cover 2, wherein a lower arc plate 3 is arranged in the box body 1, and an upper arc plate 4 is arranged in the box cover 2, wherein the lower arc plate 3 and the upper arc plate 4 are folded to form a spherical cavity; a suspended box 5 for placing the organ is placed in the lower arc plate, a counterweight 23 is arranged at the bottom of the suspended box 5, a first annular frame 6 and a second annular frame 7 of coaxial lines are sequentially sleeved on the circumference of the suspended box 5, a first rotating shaft 8 is rotatably connected between both sides of the suspended box 5 and the first annular frame 6, a second rotating shaft 9 is rotatably connected between both sides of the first annular frame 6 and the second annular frame 7, and the first rotating shaft 8 and the second rotating shaft 9 are perpendicular to each other; a plurality of telescopic rods are distributed in a circular array around the circumference of the second annular frame 7, and magnetic balls 10 adsorbed by the upper arc plate 4 and the lower arc plate 3 are arranged at the ends of the telescopic rods; a cooling liquid is arranged between the box cover 2 and the upper arc plate 4, and between the box body 1 and the lower arc plate 3.

[0023] In the present scheme, since the suspended box 5 is always in a suspended state under the action of the telescopic rod and the magnetic ball 10, when the transport box is subjected to a horizontal direction, the suspended box 5 drives the magnetic ball 10 to slide through the telescopic rods of the first annular frame 6 and the second annular frame 7, and utilizes the friction between the magnetic ball 10 and the upper arc plate 4 or the lower arc plate 3 to dissipate energy and reduce shock; and in this process, the suspended box 5, under the action of the counterweight block 23, cooperates with the rotation between the first annular frame 6 and the first rotating shaft 8 and the rotation between the second annular frame 7 and the second rotating shaft 9, so that the suspended box 5 always maintains a horizontal state during the movement, reduces the influence of external vibration on the organs and the suspended box 5, avoids the collision between the organs and the box wall, and prevents the organs from being damaged. In addition, when the transport box is subjected to external vertical force, the suspended box 5 moves vertically relative to the upper arc plate 4 and the lower arc plate 3. During this process, the telescopic characteristics of the magnetic ball 10 and the telescopic rod are utilized to ensure that the magnetic ball 10 always maintains adsorption with the arc plate or the lower arc plate 3, and friction energy is consumed simultaneously, and the first annular frame 6, the second annular frame 7 and other structures are cooperated to always maintain the vertical state of the suspended box 5.

[0024] In this embodiment, the telescopic rod includes a fixed sleeve 11 fixedly connected to the second annular frame 7, and a moving rod 12 is coaxially slidably connected in the fixed sleeve 11. The magnetic ball 10 is fixed to one end of the moving rod 12, and a hydraulic damper 13 is fixed to the other end of the moving rod 12. A slide seat 14 is fixed to the end of the hydraulic damper 13, and the width of the slide seat 14 is greater than the width of the moving rod 12 and the hydraulic damper 13; a plurality of sliding grooves are opened on both sides of the moving sleeve, and a limit rod 15 with an arc-shaped end is slidably connected in the sliding groove, and an elastic support member 16 is arranged between the limit rod 15 and the sliding groove.

[0025] In the present scheme, when the suspended box 5 moves and the telescopic rod is extended or retracted, the moving rod 12 drives the slide 14 to slide through the hydraulic damper 13. When the slide 14 abuts against one of the pairs of limit rods 15, the moving rod 12 stretches or compresses the hydraulic damper 13. At this time, the hydraulic damper 13 is used to consume energy to prevent the vibration caused by the extension and retraction of the telescopic rod from being transmitted to the suspended box 5; when the hydraulic damper 13 is stretched or compressed to a certain extent, the force of the slide 14 squeezing the limit rod 15 in the process continues to increase. At this time, the force applied to the limit rod 15 is greater than the elastic force of the elastic support 16, so that the limit rod 15 slides into the slide groove, allowing the slide 14 to continue to move until it abuts against the next pair of limit rods 15; and during the sliding process of the slide 14, the hydraulic damper 13 resets itself; during the whole process, the hydraulic damper 13 is used to consume energy in batches, effectively improving the energy consumption range of the hydraulic damper 13 within a short distance.

[0026] In this embodiment, adjacent fixed sleeves 11 are rotatably connected with a transmission shaft 17 that extends into the fixed sleeve 11. The transmission shaft 17 is rotatably connected to the fixed sleeve 11, and coaxial transmission gears 18 are welded at both ends of the transmission shaft 17; both ends of the support rod are provided with mounting grooves parallel to the support rod, and the upper end surface of the mounting groove is integrally formed with a tooth shape that meshes with the corresponding transmission gear 18 (not shown in the figure).

[0027] When the moving rod 12 moves, the moving rod 12 drives the transmission gear 18 to rotate through the toothed drive gear 18 on the mounting groove, and uses the transmission shaft 17 to drive the transmission gear 18 in the adjacent fixed sleeve 11 to rotate, so that the adjacent moving rods 12 move synchronously, and then all the moving rods 12 move synchronously, which evenly dissipates the kinetic energy received and reduces the impact on the suspended box 5.

[0028] In this embodiment, a sealing plate 19 is detachably connected between the box cover 2 and the upper arc plate 4, and between the box body 1 and the lower arc plate 3 by bolts. The sealing plate 19 is provided with a plurality of connecting holes that are opposite to each other. Branch pipes 20 are provided at the connecting holes, and valves 21 are provided at the pipe openings of the branch pipes 20. Rubber layers are provided on the facing end surfaces of the sealing plate 19. A refrigeration device (not shown in the figure) is provided in the box cover 2, and a pump (not shown in the figure) is provided at one of the branch pipes 20 on the upper arc plate 4.

[0029] When the box cover 2 is closed, the branch pipes 20 of the two sealing plates 19 are opposite to each other. At this time, the valve 21 is opened (electronically controlled, conventional technical means, so it is not described) to connect the branch pipes 20. Through the refrigeration device and the pump, the coolant is continuously circulated and cooled on the outer walls of the upper arc plate 4 and the lower arc plate 3 to ensure that the temperature at various places in the spherical cavity remains consistent.

[0030] In this embodiment, a limit block 22 is welded at the port of the fixed sleeve 11 to prevent the sliding seat 14 from sliding out.

[0031] In this embodiment, buffer rubber layers are provided on both sides of the end of the sliding seat 14 to reduce the impact when the sliding seat 14 contacts the limit rod 15, thereby preventing vibration from being transmitted into the suspended box 5 and affecting the organs.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
