Description

TECHNICAL FIELD

[0001] The present application relates to a biological sample non-destructive transport technology, in particular to a shock-absorbing constant-temperature specimen transport box. BACKGROUND

[0002] In the field of medical health, especially between the pathology department, the clinical laboratory, the operating room and the biological sample library of the hospital, the safe transport of biological samples (such as tissue specimens, blood, body fluids, cell slices, etc.) is a key link to ensure the accuracy of diagnosis and the reliability of research. These samples are often extremely sensitive to temperature and need to be maintained active or prevented from degrading under specific low-temperature conditions, and they have poor resistance to physical shock. Temperature fluctuations or mechanical shocks during transport can easily cause sample denaturation, container breakage, label loss or identification confusion, which can lead to diagnostic errors, research data invalidation and even medical disputes.

[0003] Currently, the sample transport solutions commonly used in the industry mainly rely on the following types of equipment:

[0004] Passive constant-temperature transport box: This type of equipment usually uses polyurethane or other insulation materials to make the box body, and relies on pre-cooled ice packs, ice packs or phase change materials as the cold source. For example, the patent publication number CN114537854A discloses a specimen transport box. In application, the heat exchange between the cold source and the sample is uneven, resulting in a significant temperature gradient in the box. Samples close to the cold source are likely to freeze due to overcooling, while samples away from the cold source may overheat due to insufficient insulation. The entire transport process cannot achieve precise and stable constant-temperature environment, making it difficult to meet the transport needs of valuable samples or reagents that have strict temperature requirements; moreover, the box usually has a unified temperature zone, which cannot simultaneously carry and transport multiple samples that require different storage temperatures. For complex transport tasks that require multi-temperature zone management, multiple transport boxes must be used, increasing the complexity of operation and cost.

[0005] Simple shock-absorbing transport container: This type of product is usually a layered box made of plastic or metal, which uses foam plastic, sponge pad or EVA material to fix the sample container. For example, the patent publication number CN104029917A discloses a shock-absorbing and leak-proof chromatographic detection sample transport box. In application, the buffering of this type of product relies on the static deformation of the material, which is insufficient in absorbing continuous vibration and sudden impact (such as steps and potholed roads), making it difficult to effectively protect fragile glassware or sensitive samples that are sensitive to shock.

[0006] In order to solve the problems of inaccurate temperature control, poor shock-absorbing ability and inconvenient operation in the prior art, some improvement schemes have been proposed in the prior art, for example:

[0007] 1) Patent publication number CN111268287A discloses a microbial specimen transport box. In this patent application, it includes a transport box body, a box cover for closing the transport box body, the box cover is connected with the transport box body through a hinge shaft, a placing rack for placing specimen containers is arranged in the transport box body; a central processing unit, a temperature control device, a temperature sensor, an alarm device and a power supply device are also provided; a display and control device is arranged on the box cover. The placing holes on the placing rack are used to place specimen containers, and the placing rack is separated by a flat plate between the upper and lower placing racks and is separated and fixed by a partition plate between the left and right placing racks. The present application has the following advantages: the use of temperature control device and real-time monitoring and feedback of temperature can realize effective temperature control and temperature adjustment; the fixing structure of the placing rack in the transport box body is compact, the stability of the placing rack is strong, and the specimen container is better protected; intelligent remote monitoring and viewing of data in the transport box can be realized, which is more convenient to use and has better use experience.

[0008] 2) Patent publication number CN117048995A discloses a multifunctional medical specimen fixing and transporting device. In this patent application, it includes a specimen box body, a clamping structure is arranged on the specimen box body, a pushing structure is arranged on the clamping structure, a refrigeration structure is arranged on the specimen box body, a fixing structure is arranged on the specimen box body, an illumination structure is arranged on the specimen box body, and a protection structure is arranged on the specimen box body. The clamping structure and the pushing structure cooperate to facilitate the transportation of test tubes or self-sealing bags containing specimens, avoiding the stacking of self-sealing bags or the contamination of bag openings caused by liquid shaking during transportation. The refrigeration structure and the fixing structure cooperate to maintain a low temperature in the specimen box body, preventing specimen deterioration caused by high temperature during transportation. The illumination structure and the protection structure cooperate to provide illumination when transporting specimens at night or in poorly lit environments.

[0009] The above-mentioned existing improvement schemes improve the initiative and intelligence level of temperature control to some extent, and try to enhance the stability through specific clamping or fixing structures, but these schemes still do not systematically solve the following core pain points: first, there is a lack of differentiated, adaptive fixing and shockproof mechanism for different specifications of samples (such as large volume tissue boxes and small sample tubes), the fixing slot or clamping structure has limited adaptability, and cannot achieve flexible wrapping and active buffering; second, it cannot achieve real multi-temperature zone independent precise control, the temperature environment in the box tends to be uniform, and cannot meet the synchronous transportation demand of diversified samples; third, in the sample information checking link, it still relies on opening the box or a simple observation window, and does not integrate a convenient code scanning function under sterile protection, which has the risk of contamination and the hidden danger of temperature disturbance; fourth, the functional modules (temperature control, shockproof, fixing, checking) are often in a simple superposition state, and cannot achieve collaborative optimization and space efficient use through integrated design.

[0010] Therefore, the prior art urgently needs a specimen transfer solution integrating independent and accurate temperature control of each partition, adaptive and active flexible shockproof, sterile and convenient checking, and highly integrated design. SUMMARY

[0011] The application aims to provide an anti-shock constant-temperature specimen transfer box to solve the problems of low temperature control precision, inability to manage each partition, and poor shock absorption effect in the prior art.

[0012] To achieve the above-mentioned purpose, the application provides the following technical solution: an anti-shock constant-temperature specimen transfer box, comprising:

[0013] The box body is a box-shaped heat preservation shell provided with rollers at the bottom and two groups of transverse partitions inside, the transverse partitions divide the inner cavity of the box body into a control compartment at the upper part, a storage compartment at the middle part, and an equipment compartment at the lower part, a display and control panel is arranged at the front side of the control compartment, a vertical partition is arranged inside the storage compartment, the vertical partition divides the storage compartment into a main storage cavity at the front part and a temperature control cavity at the rear part, a sealing box door is arranged outside the opening of the main storage cavity, a plurality of groups of sliding rails are arranged inside the main storage cavity along the height direction thereof, and a plurality of layers of pull-out drawer plates are slidably arranged on the plurality of groups of sliding rails; the pull-out drawer plates are used for carrying and fixing samples, the pull-out drawer plates are double-sided carrying structures, the upper end surface of the pull-out drawer plates is concave and forms a containing groove, a silica gel pad is arranged on the bottom wall of the containing groove, a first air bag and a self-locking band are arranged in the containing groove, a sample tube rack and a second air bag are arranged at the lower end of the pull-out drawer plate; a plurality of independent unitized storage modules are arranged in the temperature control cavity along the height direction thereof, each unitized storage module has an independent heat preservation shell, a unit door, and an electromagnetic lock, and a temperature sensor and an air guide structure are arranged in each heat preservation shell;

[0014] The refrigerating machine is arranged in the equipment compartment, and the output end of the refrigerating machine is divided into two paths, one of which is communicated with each unitized storage module in the temperature control cavity through a main air duct, and the other of which is communicated with the main storage cavity through an independent air supply pipeline.

[0015] Further, the first air bag is a rectangular frame type air bag, the inflation input port of which is communicated with the main air supply system through an air path integrated in the pull-out drawer plate. The rectangular frame type air bag can uniformly expand along the side wall and the bottom surface of the containing groove after inflation, and form a flexible wrapping for sample boxes of different sizes placed in the groove. The inflation shape can automatically adapt to the shape profile of the sample box, thereby effectively fixing the sample box of non-standard size or slightly smaller than the containing groove, and solving the problem that the traditional fixing structure (such as a clamping groove or a foam lining) has strict requirements on the size of the container and a narrow adaptation range.

[0016] Further, the second air bag is a ring-shaped air bag arranged around the side of the sample tube rack, and the inflation input thereof is communicated with the main air supply system through an integrated air path. After inflation, the ring-shaped air bag forms a continuous pressure belt along the periphery of the sample tube rack, uniformly shrinking from the periphery to the center, and applying a flexible tightening force to the entire sample tube rack inserted with samples. This uniform circumferential pressure can ensure that each sample tube in the rack is stably and uniformly supported laterally, effectively preventing tube-to-tube collision and overall shaking.

[0017] Further, the main air supply system includes a micro air pump and a gas distribution unit located on the lower side of the pull-out drawer, and the gas distribution unit is a multi-way proportional valve with independent channels, and each output port of the multi-way proportional valve is connected with the inflation input of the first air bag and the second air bag through a pipeline.

[0018] Further, the self-locking strap includes an electric retractor fixed on the lower side of the pull-out drawer and a restraint strap connected with the retractor, and the restraint strap passes through the first air bag, the sample box and is wound back to the retractor. The introduction of the electric retractor makes the tightening and releasing of the strap one-key operated by the main control system or linked with the state of the drawer (such as automatically tightening when the drawer is closed), without the need for manual buckling and adjusting the tightness. When the sample box needs to be taken out, the electric retractor can quickly release the restraint strap, so that the restraint strap is completely relaxed, and the operator can directly lift the sample box without manually unfastening or passing through complex knots, which is particularly suitable for use in emergency or fast and continuous sample access scenarios.

[0019] Further, the air guide structure is communicated with the main air duct in the equipment compartment through independent air guide pipelines, and each air guide pipeline is provided with an adjusting air valve.

[0020] Further, the sample tube rack is detachably fixed on the lower side of the pull-out drawer through a clamping structure, and the sample tube rack is a molded part with matrix-distributed insertion holes, and the inner wall of the insertion hole is provided with an elastic lining.

[0021] Further, the sealed box door and the unit door are each provided with a sterile code scanning window, and the sterile code scanning window comprises:

[0022] A transparent observation window composed of high-strength medical acrylic or tempered glass;

[0023] A barcode fixing groove provided on the inner side of the observation window for fixing and pasting a barcode label of a sample tube or a sample bag;

[0024] A sterile protective film covering the outer side of the observation window, and the protective film is a medical sterilization film for one-time use, which is transparent in material and allows the optical signal of the code scanning device to penetrate.

[0025] Compared with the prior art, the anti-shock constant-temperature specimen transfer box provided by the application integrates precise temperature control technology, flexible shockproof structure and sterile and convenient checking function, uses hierarchical partition design and an intelligent pneumatic execution system to build a highly integrated biological specimen safe transfer platform, which can meet the complex needs of simultaneous, safe and compliant transfer of diversified biological specimens in clinical and scientific research scenes, especially solve the differential fixing and buffering problems of coexistence of large-volume specimens and small-specification sample tubes, and overcome the technical bottlenecks of single function, poor adaptability and complicated operation of traditional equipment, and the specific technical effects include the following:

[0026] 1. By arranging a plurality of independent unitized storage modules in the rear temperature control cavity, each module is provided with an independent temperature sensor, an air guide structure and an adjusting air valve, and is independently closed-loop controlled by a main controller, so that the box body can provide different constant-temperature storage environments for different specimens at the same time, meeting the needs of complex transfer tasks, and the partition design of the front main storage cavity and the rear independent temperature control cavity, combined with the reversible double-sided pull-out drawer plate, greatly optimizes the internal space layout and improves the sample carrying diversity and flexibility per unit volume.

[0027] 2. For large-volume sample boxes, a compression fixing mechanism based on rectangular frame air bag wrapping and electric retractor belt cooperation is designed, and for small-specification sample tubes, a filling and wrapping method combining a sample tube rack and a surrounding second air bag is adopted. The rapid inflation and deflation of the air bag is realized through the micro air pump and the multi-way proportional valve located at the lower side of the pull-out drawer plate, so that the fixing structure can actively adapt to sample containers of different sizes and shapes, form dynamic buffering, effectively absorb and isolate the vibration and impact in the transportation process, and significantly reduce the damage or leakage risk of the sample caused by physical shock.

[0028] 3. The sterile code scanning window structure is integrated on the sealed box door and the unit door, which allows the operator to clearly read and identify the sample barcode information through the observation window without opening the box door, and the disposable protective film ensures the sterile state of the operation interface each time, avoids the internal temperature fluctuation, sample pollution risk and operation delay caused by opening the box for checking, and greatly improves the safety and compliance of the checking work.

[0042] 2. In an embodiment of the present application, a refrigerating machine is arranged in the equipment compartment 3, and the output of the refrigerating machine is divided into two paths, one of which is communicated with each unitized storage module 204 in the temperature-controlled cavity 202 through the main air duct, and the other is communicated with the main storage cavity 201 through an independent air supply pipeline.

[0043] 3. In an embodiment of the present application, a sterile code scanning window 11 is arranged on the sealing box door 203 and the unit door, and the sterile code scanning window 11 comprises:

[0044] a transparent observation window composed of high-strength medical acrylic or tempered glass;

[0048] As shown in the accompanying Figure 1 to the accompanying Figure 5 drawings:

[0049] Embodiment two:

[0050] The embodiment is basically same as the previous embodiment, the difference is that the pull-out drawer plate 5 is a double-sided bearing structure, the upper end surface of the pull-out drawer plate 5 is concave and forms a containing groove, the bottom wall of the containing groove is provided with a silica gel pad, the first air bag 6 and the self-locking belt 7 are arranged in the containing groove, the lower side of the pull-out drawer plate 5 is provided with a sample tube rack 8 and a second air bag 9, the first air bag 6 is a rectangular frame type air bag, and the inflation input port of the rectangular frame type air bag is communicated with the main gas supply system 10 through the gas circuit integrated in the pull-out drawer plate 5. The rectangular frame type air bag can uniformly expand along the side wall and the bottom surface of the containing groove after inflation, and form a flexible wrapping for the sample box of different sizes placed in the groove. The inflation form can automatically adapt to the contour of the sample box, so that the effective fixation of the sample box of non-standard size or slightly smaller than the containing groove is realized, and the problem that the traditional fixing structure (such as the clamping groove and the foam lining) has strict requirements on the size of the container and has a narrow adaptation range is solved. The second air bag 9 is a ring-shaped air bag arranged around the periphery of the sample tube rack 8, and the inflation input port of the ring-shaped air bag is communicated with the main gas supply system 10 through the integrated gas circuit. The ring-shaped air bag forms a continuous pressure belt along the periphery of the sample tube rack 8 after inflation, and uniformly shrinks to the center from all around, and applies a flexible tightening force to the sample tube rack with samples inserted. The uniform circumferential pressure can ensure that each sample tube in the tube rack is stably and uniformly supported, and effectively prevents the collision between the tubes and the overall shaking.

[0051] 1. In an embodiment of the application, the main gas supply system 10 includes a micro air pump and a gas distribution unit located at the lower side of the pull-out drawer plate 5, the gas distribution unit is a multi-way proportional valve with independent channels, and the output ports of the multi-way proportional valve are respectively connected with the inflation input ports of the first air bag 6 and the second air bag 9 through pipelines.

[0052] 2. In an embodiment of the application, the self-locking belt 7 includes an electric retractor fixed to the lower side of the pull-out drawer plate 5 and a restraint belt connected with the retractor, the restraint belt passes through the first air bag 6 and the sample box and is wound back to the retractor. The introduction of the electric retractor enables the tightening and releasing of the restraint belt to be operated by the main control system with one key or to be linked with the state of the drawer (such as automatically tightening when the drawer is closed), without manual buckling and adjusting the tightness. When the sample box needs to be taken out, the electric retractor can quickly release the restraint belt, so that the restraint belt is completely relaxed, and the operator can directly lift the sample box without manually unfastening or passing through complex knots, which is especially suitable for use in emergency or scenes requiring fast and continuous access to samples.

[0053] 3. In an embodiment of the application, the sample tube rack 8 is detachably fixed to the lower side of the pull-out drawer plate 5 through a clamping structure, and the sample tube rack 8 is a molded part with matrix-distributed insertion holes, and the inner wall of the insertion hole is provided with an elastic lining.

[0054] Working principle: Based on example one, the physical fixation and shock protection of the sample are optimized in example two. The core is to change the traditional passive and rigid sample carrying mode to an active and flexible intelligent fixing system. By integrating pneumatic execution unit (micro air pump, multi-way proportional valve, rectangular frame air bag, ring air bag) and electric execution unit (electric retractor), example two can dynamically adjust the fixing force and buffer form according to the size, shape and transportation state of the sample. Specifically, for large-volume sample boxes, the system realizes adaptive wrapping through the inflation and deflation of the air bag, and combines with the binding belt to provide accurate compression force; for arrayed sample tubes, uniform pressure is realized through the ring air bag to achieve overall stability. This design not only solves the compatibility problem of multiple specifications of samples, but also significantly reduces the risk of sample damage caused by vibration and impact during transportation.

[0055] In combination with the above example one and example two, the application further provides a use method of the above shock-absorbing constant-temperature specimen transfer box, comprising the following steps:

[0056] Step one: According to the transportation task requirements, the sample types are distinguished. Large-volume or conventional samples (such as tissue specimen boxes and large-capacity reagent bottles) are planned to be loaded in the front main storage cavity 201; small-volume, high-value or fine samples requiring special temperature (such as microcentrifuge tubes, precious cell cryopreservation tubes and specific temperature required test reagent cards) are planned to be stored in the independent unitized storage module 204 in the rear temperature control cavity 202. The operator starts the device self-checking through the display and control panel.

[0057] Step two: Subarea loading and differential fixation:

[0058] Front main storage cavity 201 loading: If a sample box needs to be loaded, the pull-out drawer plate 5 is configured to the first state (the accommodation groove surface faces upward). After placing the sample box, the layer fixing program is started through the display and control panel, the first air bag 6 is inflated to realize flexible wrapping, and the self-locking belt 7 is automatically tightened to complete the compression and fixation. If a sample tube needs to be loaded, the pull-out drawer plate 5 is configured to the second state (i.e. the pull-out drawer plate 5 is first pulled out and turned over by 180 degrees, so that the sample tube rack 8 faces upward). After inserting the sample tube, the layer fixing program is started through the display and control panel, and the second air bag 9 (ring air bag) is inflated to tightly clamp the entire tube rack from the circumference.

[0059] Rear temperature control cavity 202 loading: Open the unit door of the required storage unit, and directly place the fine small sample into the independent temperature preservation shell. Each unit can be independently set and maintained at a specific temperature to meet the differentiated storage requirements, and then the unit door is closed and the electromagnetic lock is automatically locked.

[0060] Step three: The bar code label on the sample container that needs to be checked is pasted or clamped into the bar code fixing groove on the inner side of the corresponding box door or unit door, and a new sterile protective film is covered outside the observation window.

[0061] Step four: After confirming the completion of loading, fixing and setting, close all the box doors. The system enters a closed-loop working mode, and the refrigeration system provides cold energy to each area according to the setting. The main controller monitors and adjusts the temperature of each temperature zone in real time. During the transfer, the real-time temperature, door lock state and other information of each partition can be checked through the display control panel or remote monitoring. The device alarms for temperature overrun and abnormal vibration.

[0062] Step five: After arriving at the destination, the authorized unlocking is performed. First, the sample information is checked through the sterile code scanning window 11 without opening the box. After checking, the corresponding storage space is opened in sequence: for the front main storage cavity 201, the sample is taken out after one-key releasing the corresponding layer air bag pressure and the binding belt; for the rear temperature control cavity 202, the fine sample is directly taken out by opening the corresponding unit door.

[0063] The above only describes some exemplary embodiments of the present application by way of illustration. It is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
