Description

Technical Field

[0001] This invention relates to the field of sample transport technology, and more particularly to a cell transport box. Background Technology

[0002] With the rapid development of cutting-edge fields such as cell therapy, regenerative medicine, genetic engineering, and biopharmaceuticals, living biological cells (such as CAR-T immune cells, stem cells, and pancreatic islet cells) have become a crucial type of "living medicine." These high-value bioactive materials often require long-distance or short-distance transportation between production centers, quality control laboratories, hospitals, and blood banks. However, cells are extremely fragile living substances, and their activity and function are highly dependent on a stable external environment. The numerous technical challenges currently faced in cell transportation severely restrict the reliability and accessibility of the cell therapy industry.

[0003] Traditional transportation methods typically use medical refrigerated boxes and dry ice containers, which mostly employ passive foam cushioning. These methods are ineffective in handling the complex dynamic environment during transport (such as frequent bumps, emergency braking, and accelerated turns). The cell containers (infusion bottles) inside the boxes are prone to shaking, tipping, and collisions. The resulting mechanical stress can directly damage cell membranes and internal structures, leading to a significant decrease in cell viability. Furthermore, during the entire transportation process, when the vehicle accelerates or brakes, the traditional boxes can tilt forward or backward due to inertia, exacerbating the shaking of the internal containers and posing a significant risk of physical damage to the cells.

[0004] The existing patent document (publication number: CN118387473A) discloses a cell transport incubator. This incubator uses a honeycomb-shaped sample chamber within its shell, dividing the chamber into several sample cavities for holding sample tubes containing cells. From the inside out, each sample cavity contains a villous layer, a vacuum layer, and a pressure-resistant insulation layer. The villous layer consists of long and short fibers. The long fibers are made of hard silicone with silicone tips applied to their ends. These tips adhere to the sample tubes when pressed downwards, stabilizing them within the sample cavity. Simultaneously, the densely packed short fibers form an air layer on the inner wall of the sample cavity. This dense microbubble layer achieves insulation, while the metal plating on the outer wall of the vacuum layer slows heat entry into the sample cavity from the outside. The pressure-resistant insulation layer consists of water-containing microspheres or silicone spheres filling the inner wall of the sample cavity. The surface adsorption of these microspheres or silicone spheres provides good insulation while also exhibiting excellent pressure resistance.

[0005] Although the aforementioned cell transport incubators can meet the requirements for cell transport, they inevitably encounter frequent bumps, emergency braking, and accelerated turns during use, which can cause mechanical stress damage to the cell samples inside the incubator due to impact inertia. Summary of the Invention

[0006] In view of this, the present invention proposes a cell transport box to solve the problem of mechanical stress damage to cell samples inside the incubator caused by impact inertia due to frequent bumps, emergency braking, and accelerated turns that are unavoidable during use.

[0008] Based on the above technical solutions, preferably, the system also includes a sample placement rack and a linkage assembly; a movable door is provided on one side of the insulated chamber, with both sides of the movable door hinged to the inner wall of the insulated chamber, and the movable door can be rotated vertically relative to the insulated chamber; the sample placement rack is placed inside the insulated chamber, and samples are loaded on the sample placement rack, which can move horizontally relative to the insulated chamber; the linkage assembly is located inside the insulated chamber and is connected between the sample placement rack and the movable door; when the movable door is rotated and opens or closes the insulated chamber, the linkage assembly drives the sample placement rack to move out of the insulated chamber or return to its original position.

[0009] More preferably, the sample placement rack includes shelves, and the linkage assembly includes a fixing sleeve, a push rod, and a drive rod; several shelves are spaced apart vertically, with a through hole in the center of each shelf, and the shelves can move horizontally relative to the insulation box; the fixing sleeve is located below the bottom shelf; one end of the push rod is hinged to or abuts against the inner wall of the movable door, and the other end of the push rod extends horizontally through the insulation box of the fixing sleeve, and the push rod moves horizontally relative to the fixing sleeve; one end of the drive rod is hinged to the inner end of the push rod, and the other end of the drive rod extends upward and passes through the through holes on several shelves in sequence.

[0010] In a further preferred embodiment, horizontal rail grooves are provided on the inner walls of both sides of the insulated box, and the two sides of the shelf are set in the rail grooves, allowing the shelf to move along the rail grooves.

[0011] More preferably, the sample placement rack also includes a sample box and a clamping and buffering assembly. The shelf is provided with several placement slots that protrude downwards from the shelf. The sample box is loaded into the placement slot and contains a sample. The clamping and buffering assembly is disposed in the placement slot and clamps and buffers the sample box.

[0012] More preferably, the clamping and buffering assembly includes a rotating rod, an adsorption element, and a buffer plate; a plurality of clamping and buffering assemblies are arranged around the placement groove; the rotating rod is vertically arranged outside the placement groove, with its middle part hinged to the outer peripheral wall of the placement groove, and both ends of the rotating rod swinging relative to the placement groove around the hinged connection, with both ends of the rotating rod passing through the outer wall of the placement groove and inserting into the placement groove; the adsorption element and the buffer plate are both arranged on the inner peripheral wall of the placement groove, and the adsorption element and the buffer plate are respectively arranged at the upper and lower ends of the rotating rod.

[0013] In a further preferred embodiment, the bottom surface of the placement slot has a window opening. In the initial state, the bottom surface of the placement slot is convex upwards and spherical. When the sample box is placed into the placement slot, the bottom surface of the placement slot is squeezed downwards and protrudes.

[0014] More preferably, the bottom end face of the placement groove is provided with a number of deformation strips around the window hole. The two ends of the deformation strips extend radially along the window hole and extend to the edge of the window hole and the edge of the bottom end face of the placement groove, respectively.

[0015] Even more preferably, a corrugated hose is connected between the adsorption component and the end of the rotating rod.

[0016] Based on the above technical solutions, preferably, the top of the insulated box is symmetrically equipped with handles.

[0017] The cell transport box of the present invention has the following advantages over the prior art: (1) The present invention has a damping block movably installed at the upper end of the interior of the heat preservation box. The damping block can slide in the cross-shaped groove at the upper end of the heat preservation box. When the heat preservation box suddenly tilts due to inertia, the pull rope will pull the damping block, causing the damping block to move in the opposite direction of the tilt of the heat preservation box, thereby changing the center of gravity of the heat preservation box to counteract the inertial torque of the heat preservation box and maintain the stability of the heat preservation box under various sudden conditions, thereby preventing the sample container placed inside from shaking violently due to inertia.

[0018] (2) By setting the movable door to be rotatable, and setting the rotation point of the movable door and the insulated box near the bottom of the insulated box, and the sample placement rack is connected to the movable door through a linkage component, when the personnel rotate the movable door, the linkage component will drive the sample placement rack to move outward synchronously to the outside of the insulated box, which makes it easy for personnel to quickly and conveniently take out the sample, while not excessively exposing the inner cavity of the insulated box and greatly shortening the sample exposure time, significantly reducing the risk of microbial contamination during operation. Users can quickly and easily take out and put in the container with one hand while minimizing the opening of the movable door, greatly shortening the exposure time and significantly reducing the risk of microbial contamination during operation.

[0019] (3) The present invention also provides a fixing seat, which can be conveniently and detachably attached to a vehicle with limited conditions by means of suction cups at its bottom, avoiding instability caused by direct placement on the vehicle. At the same time, the elastic pad on the inner wall of the fixing seat can effectively buffer the impact and vibration from all directions, minimizing the mechanical damage to cells caused by physical vibration during transportation, and ensuring the integrity of cell morphology and function.

[0020] (4) The present invention provides a placement slot on the sample placement rack, which can store a sample box separately, avoiding the collision and breakage caused by multiple sample containers being stored at the same time. In addition, each placement box is provided with a clamping buffer component, which can fix the sample box from multiple horizontal and vertical directions. While fixing the sample box, it can also buffer and protect the sample box from small displacements during transportation, minimizing mechanical damage to cells caused by physical vibration during transportation and ensuring the integrity of cell morphology and function.

[0030] like Figure 1 As shown, combined with Figure 2 and Figure 3 The present invention provides a cell transport box, comprising an insulated box body 1, a fixing box 2, a suction cup 3, a damping block 4, a spring 5, and a pull rope 6.

[0031] The incubation chamber 1 has a square structure and is made of insulating material. The inner wall of the chamber 1 also features a composite material layer made of boron-containing polyethylene (BPE) and tungsten nanoparticles. This layer effectively shields against ionizing radiation such as X-rays, providing full radiation protection for the cells within the chamber 1 and ensuring the stability of their genetic material and the safety of the treatment. The incubation chamber 1 contains the sample. Four grooves 101 are formed on the inner wall of the top of the chamber 1. The adjacent ends of the four grooves 101 are interconnected and form a cross.

[0032] The top of the fixing box 2 is open, and elastic pads 21 are provided on the four inner peripheral walls of the fixing box 2. The fixing box 2 is located at the bottom of the heat preservation box 1, and the elastic pads 21 elastically clamp the bottom of the heat preservation box 1.

[0033] Several suction cups 3 are installed at the bottom of the fixing box 2, and the suction cups 3 are used to attach and fix the fixing box 2. Damping blocks 4 are installed at the intersection of four sliding grooves 101, and the damping blocks 4 move along the sliding grooves 101. The fixing seat 2 is attached to the vehicle, such as an airplane, high-speed train or bicycle, by the suction cups 3, so that the fixing seat 2 and the vehicle are a whole. When the insulated box 1 is placed in the fixing seat 2, in order to ensure the stability of the insulated box 1, the elastic pad 21 of the fixing seat 2 buffers the displacement of the insulated box 1, and avoids the external force applied to the insulated box 1 alone causing the insulated box 1 to shake rapidly, and prevents the insulated box 1 from displacing too much during transportation.

[0034] Four springs 5 ​​are respectively installed in four slide grooves 101, and the two ends of the springs 5 ​​are respectively connected to the side of the damping block 4 and the end of the slide groove 101.

[0035] Four pull ropes 6 are arranged around the damping block 4. One end of the pull rope 6 is connected to the fixed box 2, and the other end of the pull rope 6 passes through the outer wall of the insulation box 1, inserts into the slide groove 101, and is connected to the side of the damping block 4.

[0036] When the insulated box 1 vibrates or is impacted, since the fixed box 2 and the insulated box 1 inside are in elastic soft contact through the elastic pad 21, it is difficult to avoid the insulated box 1 tilting due to inertia. At this time, the four pull ropes 6 pull the damping block 4, so that the damping block 4 is fixed in position relative to the fixed box 2. At the same time, the damping block 4 will move in one of the slide grooves 101. The relative movement direction of the damping block 4 is opposite to the tilting direction of the insulated box 1, thus changing the center of gravity of the transport box device as a whole, thereby changing the center of gravity of the insulated box 1 to counteract the inertial torque of the insulated box 1, maintaining the stability of the insulated box 1 under various sudden conditions, thereby preventing the sample container placed inside from shaking violently due to inertia.

[0037] exist Figure 4 and Figure 5In one embodiment shown, the sample placement rack 7 and linkage component 8 are also included.

[0038] The insulated chamber 1 has a movable door 11 on one side. Both sides of the movable door 11 are hinged to the inner wall of the insulated chamber 1. The movable door 11 flips vertically relative to the insulated chamber 1, allowing the user to retrieve samples from inside. The movable door 11 has a square structure to fit the shape of the insulated chamber 1. A HEPA-activated carbon composite filter is installed inside the movable door 11 to create a sterile environment. The movable door 11 is rotatably connected to the insulated chamber 1 via a pivot and pivot seat. The pivot and pivot seat are located near the lower end of the insulated chamber 1. The precise location of the pivot and pivot seat can be determined based on the height of the sample rack 7 and the insulation requirements; this embodiment only provides a general location.

[0039] The sample placement rack 7 is set inside the insulated box 1, and the sample is loaded on the sample placement rack 7. The sample placement rack 7 moves horizontally relative to the insulated box 1.

[0040] The linkage component 8 is installed inside the insulated chamber 1 and is connected between the sample placement rack 7 and the movable door 11. When the movable door 11 is flipped open or closed, the linkage component 8 moves the sample placement rack 7 outward or back into the insulated chamber 1. The sample placement rack 7 is connected to the movable door 11 via the linkage component 8, so that when personnel rotate the movable door 11, the linkage component 8 will move the sample placement rack 7 outward synchronously to the outside of the insulated chamber. This allows personnel to quickly and conveniently retrieve samples without excessively exposing the inner cavity of the insulated chamber and greatly shortening the sample exposure time, significantly reducing the risk of microbial contamination during operation. Users can quickly and easily retrieve and place containers with one hand while minimizing the opening of the movable door 11, greatly shortening the exposure time and significantly reducing the risk of microbial contamination during operation.

[0041] exist Figure 6 and Figure 7 In one embodiment shown, the sample placement rack 7 includes a shelf 71, and the linkage assembly 8 includes a fixing sleeve 81, a push rod 82, and a drive rod 83.

[0042] Among them, several layers 71 are arranged vertically at intervals, and a through hole 701 is opened in the center of the layer 71. The through hole 701 is an elongated hole, and the layer 71 moves horizontally relative to the heat preservation box 1.

[0043] The fixing sleeve 81 is located below the bottommost shelf 71.

[0044] One end of the push rod 82 is hinged to or abuts against the inner wall of the movable door 11, and the other end of the push rod 82 extends horizontally through the fixed sleeve 81 and into the heat-insulating box 1. The push rod 82 moves horizontally relative to the fixed sleeve 81.

[0045] One end of the drive rod 83 is hinged to the inner end of the push rod 82, and the other end of the drive rod 83 extends upward and passes through the through holes 701 on several layers 71 in sequence.

[0046] When the above technical solution is adopted, when the movable door 11 is flipped outward and the heat preservation box 1 is opened, the movable door 11 flips inward and pushes the push rod 82 to move inward. The push rod 82 then pries the top of the drive rod 83 to move outward from the heat preservation box 1. The push rod 82 is in an inclined position. The push rod 82 passes through the through hole 101 in the middle of each layer plate 71, which will also drive the front end of each layer plate 71 to move outward from the heat preservation box 1 along with the movable door 11. The outward movement distance of the upper layer plate 71 is greater than that of the lower layer plate 71. When the movable door 11 is flipped inward and the heat preservation box 1 is closed, the movable door 11 will push each layer plate 71 to retreat and reset, and the linkage component 8 will also reset accordingly.

[0047] exist Figure 8 and Figure 9 In one embodiment shown, horizontal rail grooves 102 are provided on the inner walls of both sides of the heat preservation box 1, and the two side edges of the shelf 71 are arranged in the rail grooves 102, so that the shelf 71 can move smoothly along the rail grooves 102.

[0048] exist Figure 10 In one embodiment shown, the sample placement rack 7 further includes a sample box 72 and a clamping buffer assembly 73.

[0049] The shelf 71 is provided with several placement slots 711, which protrude downwards from the shelf 71; the sample box 72 is loaded in the placement slots 711 and contains the sample.

[0050] Clamping and buffering components 73 are disposed within placement slots 711, clamping and buffering the sample boxes 72. Each clamping and buffering component 73 in each placement slot 711 can independently fix a single sample box 72 from multiple horizontal and vertical directions. While fixing the sample box, it also buffers and protects against small displacements of the sample box during transportation, minimizing mechanical damage to cells caused by physical vibration during transportation, ensuring the integrity of cell morphology and function, and preventing sample breakage due to collision.

[0051] exist Figure 11 In one embodiment shown, the clamping buffer assembly 73 includes a rotating rod 731, an adsorption member 732, and a buffer plate 733.

[0052] Several clamping and buffering components 73 are arranged around the placement slot 711.

[0053] The rotating rod 731 is vertically installed outside the placement groove 711. The middle part of the rotating rod 731 is hinged to the outer peripheral wall of the placement groove 711. The two ends of the rotating rod 731 swing around the hinged connection relative to the placement groove 711. The two ends of the rotating rod 731 pass through the outer wall of the placement groove 711 and are inserted into the placement groove 711.

[0054] The adsorption element 732 and the buffer plate 733 are both set on the inner peripheral wall of the placement groove 711, and the adsorption element 732 and the buffer plate 733 are respectively set at the upper and lower ends of the rotating rod 731.

[0055] When the above technical solution is adopted, when the sample box 72 is placed in the placement slot 711, the upper part of the outer peripheral wall of the sample box 72 will be attracted by multiple adsorption components 732 at the same time, while the bottom of the outer peripheral wall of the sample box 72 will be buffered and protected from multiple horizontal directions by multiple buffer plates 733; the movable rotating rod 731 ensures the free adaptability of the sample box 72 when it is placed in the placement slot 711.

[0056] exist Figure 12 In one embodiment shown, the placement groove 711 is made of a flexible material, such as silicone. A window 712 is provided on the bottom surface of the placement groove 711. Initially, the bottom surface of the placement groove 711 is convex upwards in a spherical shape. When the sample box 72 is placed into the placement groove 711, the bottom surface of the placement groove 711 is compressed downwards, and the window 712 expels the air at the bottom of the placement groove 711 when the sample box 72 is placed in the placement groove 711. The air on both sides of the placement groove 711 then compresses the buffer plate 733, and the lever 731 further pushes the adsorption member 732 to enhance the adsorption of the sample box 72.

[0057] exist Figure 13 In one embodiment shown, a plurality of deformation strips 713 are provided around the bottom end face of the placement groove 711 around the window hole 712. The two ends of the deformation strips 713 extend radially along the window hole 712 and extend to the edge of the window hole 712 and the edge of the bottom end face of the placement groove 711, respectively. The plurality of deformation strips 713 elastically deform and cause the bottom surface of the placement groove 711 to bulge upward or downward. The function of the deformation strips 713 is to drive the bottom surface of the placement groove 711 to deform and return to its original position.

[0058] exist Figure 14 In one embodiment shown, a corrugated hose 734 is connected between the adsorption element 732 and the end of the rotating rod 731. The corrugated hose 734 acts as a buffer to prevent the adsorption element 732 from being subjected to hard compression by the rotating rod 731.

[0059] exist Figure 1 In one embodiment shown, the top of the insulated box 1 is symmetrically provided with handles 12, which makes it convenient for users to lift the insulated box 1 and put or pull the insulated box 1 into or out of the fixing box 2.

[0060] 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 within the protection scope of the present invention.
