Technical Field

[0001] This invention belongs to the field of specimen storage technology, and particularly relates to a specimen storage and transportation box. Background Technology

[0002] In clinical practice, to accurately and promptly monitor patients' health status, professional medical analysis of their bodily fluids and tissue specimens is necessary. Currently, various patient specimens, including blood, tissue fluid, and stool / urine samples, are transported using either pipelines or manually. Pipelines offer speed and timeliness, but their shock absorption is uncertain. Manual transport is costly and not always timely. With the development of precision medicine, correspondingly higher demands are placed on accurate diagnosis. Clinical departments collect specimens and send them to testing centers. To ensure testing quality, higher requirements are placed on specimen storage and transportation, necessitating convenient storage for frontline clinical staff while meeting the requirements for shock absorption, cold preservation, and timely delivery for testing.

[0003] Chinese patent application number CN202111282044.4 discloses a portable medical specimen storage and transportation box, including a box body and a lid, with the lid rotatably connected to the top surface of the box body. The box body contains an upper specimen box and a lower drawer box. The upper specimen box has a cross-shaped divider that divides it into four storage compartments, each containing a square specimen shelf and a circular specimen shelf. The lower drawer box is located at the bottom of the box body and slides smoothly against it. The lower drawer box contains a fecal specimen shelf. The bottom surface of the box body is... The advantages of this paper compared to existing technologies are as follows: it adopts a layered design, which is convenient to use and can effectively avoid cross-contamination between specimens, ensuring the quality of specimen delivery; the upper and lower specimen boxes use flip-top and drawer opening methods respectively, solving the current problem of mixed specimen storage; the bottom is equipped with a brakeable pulley system, which facilitates transportation and can also fix it in place. However, in actual use, in order to ensure the activity of the samples in the specimen storage and transportation box, the temperature of the specimen storage and transportation box must be controlled and the cold source must be replaced in time to avoid the samples losing activity due to temperature loss. Summary of the Invention

[0004] The purpose of this invention is to provide a specimen storage and transport box to solve the problem of quickly changing the cold source.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A specimen storage and transport box includes a base, a groove on one side of the base, an ice storage tank slidably connected in the groove, a connecting plate fixedly connected to one side of the ice storage tank, a limit sealing component provided in the connecting plate, a first box and a second box sequentially arranged on the top of the base, a buffer block fixedly connected to the bottom of the first box and the second box, the bottom of the buffer block fixedly connected to the top of the base, multiple through pipes fixedly connected to the bottom of the first box and the second box, one end of the through pipe away from the first box and the second box extending into the groove, a flow control component provided in the through pipe, a bracket movably connected to the first box and the second box, multiple placement cylinders fixedly connected in the bracket, a clamping and stabilizing component provided on the top outer surface of the placement cylinder;

[0007] The limiting sealing assembly includes a cam. A cavity is formed inside the connecting plate. A rotating shaft is fixedly connected to both sides of the cam. Bearings are embedded in both sides of the inner wall of the cavity, and the rotating shaft is rotatably connected to the bearing. One end of the rotating shaft extends to the outside of the cavity and is fixedly connected to a knob. Sliding plates are attached to both sides of the cam. The four sides of the sliding plates are attached to the four sides of the inner wall of the cavity. A limiting rod is fixedly connected to the side of the sliding plate away from the cam. A sliding groove is formed inside the connecting plate and is connected to the cavity. The limiting rod is slidably connected to the sliding groove. Limiting grooves are formed on both sides of the inner wall of the groove, and the limiting rod is engaged with the limiting groove.

[0008] The top of the support has several placement tubes for inserting test tubes. Blood and tissue specimens are placed in the test tubes. The placement tubes have buffer rings around their edges to prevent the test tubes from wobbling and to protect the outer walls of the test tubes.

[0009] As a further description of the above technical solution:

[0010] A second spring is sleeved on the outer surface of the limiting rod, and the two ends of the second spring are fixedly connected to one side of the sliding plate and one side of the inner wall of the cavity, respectively.

[0011] As a further description of the above technical solution:

[0012] A mounting bracket is fixedly connected to one side of the connecting plate. A sliding hole is opened on one side of the mounting bracket, and a locking rod is slidably connected in the sliding hole. The knob has locking grooves around its perimeter, and the locking rod engages with the locking grooves. A second limiting plate is fixedly connected to the outer surface of one end of the locking rod. One side of the second limiting plate is in contact with one side of the knob. A third spring is sleeved on the outer surface of the locking rod, and the two ends of the third spring are fixedly connected to one side of the mounting bracket and one side of the second limiting plate, respectively.

[0013] As a further description of the above technical solution:

[0014] Multiple airbags are fixedly connected to both sides of the inner wall of the cavity. The side of the airbag away from the inner wall of the cavity is fixedly connected to the side of the sliding plate. A sealing air ring is fixedly connected to the outside of the connecting plate. A connecting tube is fixedly connected to one end of the airbag. The end of the connecting tube away from the airbag is fixedly connected to the side of the sealing air ring.

[0015] By setting up a limiting sealing component, the operator rotates a knob, which drives a cam to rotate. The cam, through a sliding plate, moves a limiting rod to one side, causing the limiting rod to engage with the limiting groove, thus fixing the connecting plate to the base. Simultaneously, the sliding plate causes the airbag to contract and transports the air inside the airbag to the sealing ring through a connecting pipe, causing the sealing ring to expand. The sealing ring then fits tightly against the inner wall of the groove, enabling the cold source to be replaceable. In actual use, this allows for rapid replacement of the cold source. At the same time, the sealing ring improves the sealing performance inside the groove, preventing cold air from leaking out from the gaps, thus extending the cooling time of the cold source and improving the cooling effect on the first and second chambers.

[0016] As a further description of the above technical solution:

[0017] The flow control assembly includes a connecting ring, which is fixedly connected to the inside of the pipe. An installation rod is fixedly connected to the inner side of the connecting ring, and the same installation box is fixedly connected between two installation rods. Multiple sealing fan blades are provided between the installation box and the connecting ring. A connecting shaft is fixedly connected to both ends of the sealing fan blades. Bearings are provided on one side of the connecting ring and one side of the installation box, and the connecting shaft is rotatably connected to the bearings.

[0018] By setting up a flow control component, cold air enters the first or second chamber through a pipe. Simultaneously, a motor drives a rotating disk via a shaft, which in turn drives a transmission gear via a gear ring. This transmission gear, in turn, drives the sealing fan blades via a connecting shaft, causing the deflection angle of each sealing fan blade to change. This alters the amount of cold air entering the first and second chambers, controlling the temperature within them. Furthermore, during the replacement of the cold source, the sealing fan blades adhere to each other, sealing the pipe and isolating the first and second chambers from the base groove. This prevents external heat sources from affecting the temperature within the first and second chambers during cold source replacement, ensuring the stability of the sample storage environment.

[0019] As a further description of the above technical solution:

[0020] One end of the connecting shaft extends into the mounting box and is fixedly connected to a transmission gear. A gear ring meshes with one side of the transmission gear, and a rotating plate is fixedly connected to one side of the gear ring. A motor is fixedly installed inside the mounting box. One end of the motor output shaft is fixedly connected to a rotating shaft, and one end of the rotating shaft is fixedly connected to one side of the rotating disk.

[0021] As a further description of the above technical solution:

[0022] The clamping and stabilizing assembly includes a rotating ring rotatably connected to the outside of the placement cylinder. The rotating ring has an inner cavity, and the outer side of the placement cylinder has multiple sliding holes. A sliding rod is slidably connected to each sliding hole. One end of the sliding rod is fixedly connected to a bonding plate. The bonding plate has a circular cross-sectional shape and is made of flexible plastic. The end of the sliding rod away from the sliding rod extends into the inner cavity and is fixedly connected to a first limiting plate. A compression wheel is fixedly connected to the side of the first limiting plate away from the sliding rod. A first spring is sleeved on the outer surface of the sliding rod. The two ends of the first spring are fixedly connected to one side of the first limiting plate and one side of the outer wall of the placement cylinder, respectively.

[0023] By setting up a clamping and stabilizing component, the operator rotates the rotating ring, which drives the squeezing wheel to move via the squeezing block. The squeezing wheel then drives the sliding rod to move via the first limiting plate. The sliding rod drives the bonding plate to move and securely bond the sample tube. At this time, the limiting block engages with the limiting hole to prevent the rotating ring from rotating back, ensuring the bonding effect between the bonding block and the sample tube. This allows the clamping and stabilizing component to be applicable to sample tubes of different diameters. Furthermore, the cooperation of the bonding block improves the stability of the stored sample tubes, which is beneficial for improving the stability of transportation.

[0024] As a further description of the above technical solution:

[0025] Multiple extrusion blocks are fixedly connected inside the rotating ring. The extrusion blocks are in contact with the extrusion wheel. The cross-sectional shape of the extrusion blocks is trapezoidal, and the multiple extrusion blocks are distributed in an equiangular array.

[0026] As a further description of the above technical solution:

[0027] The top of the bracket has multiple limiting holes, and the bottom sides of the rotating ring are fixedly connected to limiting blocks. The limiting blocks are engaged with the limiting holes, and the multiple limiting holes are distributed in an equiangular array along the axis of the placement cylinder.

[0028] As a further description of the above technical solution:

[0029] Both the first and second boxes are equipped with a sealed door on one side, and an observation window is provided on one side of the sealed door. Both the first and second boxes are fixedly connected to a display screen on the top. Both the first and second boxes are fixedly equipped with an alarm bell on the top. An ice water bath is fixedly connected to the bottom of the inner wall of the second box, and the bottom of the placement cylinder is in contact with the ice water in the ice water bath. A storage drawer is fixedly connected to the top of the inner wall of the second box.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. In this invention, by setting a limiting sealing component, the operator rotates the knob, which drives the cam to rotate. The cam drives the limiting rod to move to one side through the sliding plate, so that the limiting rod and the limiting groove are engaged with each other, realizing the fixed installation of the connecting plate and the base. At the same time, the sliding plate drives the airbag to contract and transports the air in the airbag to the sealing ring through the connecting pipe, so that the sealing ring expands and fits tightly against the inner wall of the groove, realizing the replaceability of the cold source. In actual use, the cold source can be quickly replaced. At the same time, the sealing ring improves the sealing performance inside the groove, preventing the cold air from the cold source from flowing out of the gaps, thus extending the cooling time of the cold source and improving the cooling effect inside the first box and the second box.

[0032] 2. In this invention, by setting up a flow control component, cold air enters the first or second chamber through a pipe. At the same time, the motor drives the rotating disk to rotate through the rotating shaft. The rotating disk drives the transmission gear to rotate through the gear ring. The transmission gear drives the sealing fan blades to rotate through the connecting shaft, thereby changing the deflection angle of each sealing fan blade, thus changing the amount of cold air entering the first and second chambers, controlling the temperature inside the first and second chambers. Furthermore, during the replacement of the cold source, the sealing fan blades are in contact with each other, sealing the pipe and isolating the first and second chambers from the base groove. This prevents external heat sources from affecting the temperature inside the first and second chambers during the replacement of the cold source, ensuring the stability of the sample storage environment.

[0033] 3. In this invention, by setting up a clamping and stabilizing component, the operator rotates the rotating ring, which drives the extrusion wheel to move via the extrusion block. The extrusion wheel drives the slide rod to move via the first limiting plate, and the slide rod drives the bonding plate to move and stabilize the sample tube. At this time, the limiting block engages with the limiting hole to prevent the rotating ring from rotating back, ensuring the bonding effect between the bonding block and the sample tube. This allows the clamping and stabilizing component to be applicable to sample tubes of different diameters. Furthermore, the stability of the stored sample tubes is improved through the cooperation of the bonding block, which is beneficial to improving the stability of transportation.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1 - Figure 8The present invention provides a technical solution:

[0046] A specimen storage and transport box includes a base 1. A groove is formed on one side of the base 1, and an ice storage tray 16 is slidably connected within the groove. A connecting plate 2 is fixedly connected to one side of the ice storage tray 16, and a limit sealing component 5 is disposed within the connecting plate 2. A first box 9 and a second box 11 are sequentially arranged on the top of the base 1. A buffer block 12 is fixedly connected to the bottom of the first box 9 and the second box 11, and the bottom of the buffer block 12 is fixedly connected to the top of the base 1. Multiple through-tubes 15 are fixedly connected to the bottom of both the first box 9 and the second box 11. One end of each through-tube 15, away from the first box 9 and the second box 11, extends into the groove. A flow control component 4 is disposed within each through-tube 15. Both the first box 9 and the second box 11 are movably connected to a bracket 13. Multiple placement cylinders 14 are fixedly connected inside the bracket 13. The top outer surface of each placement cylinder 14 is provided with a clamping and stabilizing component 3. Both the first box 9 and the second box 11 are provided with a sealing door 7 on one side. An observation window 6 is opened on one side of the sealing door 7. Both the first box 9 and the second box 11 are fixedly connected to a display screen 10. Both the first box 9 and the second box 11 are fixedly provided with an alarm bell 8. An ice water bath 18 is fixedly connected to the bottom of the inner wall of the second box 11. The bottom of the placement cylinder 14 is in contact with the ice water in the ice water bath 18. A storage drawer 17 is fixedly connected to the top of the inner wall of the second box 11.

[0047] The flow control component 4 includes a connecting ring 408, which is fixedly connected to the through pipe 15. An installation rod 401 is fixedly connected to the inner side of the connecting ring 408, and the same installation box 403 is fixedly connected between the two installation rods 401. Multiple sealing fan blades 409 are arranged between the installation box 403 and the connecting ring 408. A connecting shaft 406 is fixedly connected to both ends of the sealing fan blades 409. A bearing is provided on one side of the connecting ring 408 and one side of the installation box 403. The connecting shaft 406 is rotatably connected to the bearing. One end of the connecting shaft 406 extends into the installation box 403 and is fixedly connected to a transmission gear 407. A gear ring 405 meshes with one side of the transmission gear 407. A rotating plate is fixedly connected to one side of the gear ring 405. A motor 402 is fixedly installed in the installation box 403. A rotating shaft is fixedly connected to one end of the output shaft of the motor 402, and one end of the rotating shaft is fixedly connected to one side of the rotating disk 404.

[0048] The specific implementation method is as follows: By setting the flow control component 4, cold air enters the first chamber 9 or the second chamber 11 through the through pipe 15. At the same time, the motor 402 drives the rotating disk 404 to rotate through the rotating shaft. The rotating disk 404 drives the transmission gear 407 to rotate through the gear ring 405. The transmission gear 407 drives the sealing fan blades 409 to rotate through the connecting shaft 406, so that the deflection angle of each sealing fan blade 409 changes, thereby changing the amount of cold air entering the first chamber 9 and the second chamber 11, controlling the temperature inside the first chamber 9 and the second chamber 11. During the replacement of the cold source, the sealing fan blades 409 are in contact with each other, so that the through pipe 15 is closed, isolating the first chamber 9 and the second chamber 11 from the groove of the base 1, avoiding the influence of external heat sources on the temperature inside the first chamber 9 and the second chamber 11 during the replacement of the cold source, and ensuring the stability of the sample storage environment. At the same time, the ice water bath in the second chamber 11 can perform ice water bath treatment on the samples in the placement cylinder 14. An alarm bell is set. The specimen storage and transport boxes are located on the top surfaces of the first box 9 and the second box 11 and are connected to the processing module (microcontroller). Both the first and second boxes 11 are equipped with temperature sensors, which are connected to the processing module (microcontroller). The temperature is displayed on the first display screen. When the temperature inside the specimen box exceeds a preset value, an alarm is triggered by ringing a bell. The first box 9 and the second box 11 are also equipped with a second display screen and a signal receiving module, which are electrically connected. The second display screen is installed in the transport personnel's work area. The signal receiving module receives instruction signals from the communication module and displays them on the second display screen. The signal receiving module can simultaneously receive information from several specimen storage and transport boxes distributed in different wards and centrally display on the second display screen which wards have specimens that need to be transported, facilitating reasonable route planning and saving time for transport personnel. The bell is located on the top surfaces of the first box 9 and the second box 11 and is connected to the processing module (microcontroller). The first chamber 9 and the second chamber 11 are respectively equipped with temperature sensors. The temperature sensors are connected to the processing module (microcontroller). The temperature is displayed on the first display screen. When the temperature inside the specimen chamber is higher than the preset value, an alarm will be triggered by ringing a bell.

[0049] The clamping and stabilizing assembly 3 includes a rotating ring 301, which is rotatably connected to the outside of the placement cylinder 14. The rotating ring 301 has an inner cavity. The placement cylinder 14 has multiple sliding holes on its outer side, and a sliding rod 304 is slidably connected within each hole. One end of the sliding rod 304 is fixedly connected to an adhesive plate 305, which has a circular cross-sectional shape and is made of flexible plastic. The end of the sliding rod 304 away from the sliding rod 304 extends into the inner cavity and is fixedly connected to a first limiting plate 302. A compression wheel 306 is fixedly connected to the side of the first limiting plate 302 away from the sliding rod 304. The outer surface of the sliding rod 304... A first spring 303 is sleeved on the sleeve. The two ends of the first spring 303 are fixedly connected to one side of the first limiting plate 302 and one side of the outer wall of the placement cylinder 14, respectively. A plurality of extrusion blocks 307 are fixedly connected inside the rotating ring 301. The extrusion blocks 307 are in contact with the extrusion wheel 306. The cross-sectional shape of the extrusion blocks 307 is trapezoidal, and the plurality of extrusion blocks 307 are distributed in an equiangular array. A plurality of limiting holes 309 are opened on the top of the bracket 13. Limiting blocks 308 are fixedly connected to both sides of the bottom of the rotating ring 301. The limiting blocks 308 are engaged with the limiting holes 309, and the plurality of limiting holes 309 are distributed in an equiangular array along the axis of the placement cylinder 14.

[0050] The specific implementation method is as follows: By setting up a clamping and stabilizing component, the operator rotates the rotating ring 301. The rotating ring 301 drives the squeezing wheel 306 to move through the squeezing block 307. The squeezing wheel 306 drives the sliding rod 304 to move through the first limiting plate 302. The sliding rod 304 drives the bonding plate 305 to move and bond and stabilize the sample tube. At this time, the limiting block 308 is engaged with the limiting hole 309 to prevent the rotating ring 301 from rotating back, ensuring the bonding effect between the bonding block and the sample tube. This allows the clamping and stabilizing component 3 to be applicable to sample tubes of different diameters. Through the cooperation of the bonding block, the stability of the stored sample tubes is improved, which is beneficial to improving the stability of transportation.

[0051] The limiting sealing assembly 5 includes a cam 506. A cavity 507 is formed inside the connecting plate 2. Rotary shafts are fixedly connected to both sides of the cam 506. Bearings are embedded on both sides of the inner wall of the cavity 507, and the rotating shafts are rotatably connected within the bearings. One end of the rotating shaft extends to the outside of the cavity 507 and is fixedly connected to a knob 515. Sliding plates 505 are attached to both sides of the cam 506. The sliding plates 505 are in contact with the periphery of the inner wall of the cavity 507. The sliding plates 505 are located away from... A limiting rod 503 is fixedly connected to one side of the cam 506. A sliding groove is provided inside the connecting plate 2, and the sliding groove communicates with the cavity 507. The limiting rod 503 is slidably connected within the sliding groove, and limiting slots 501 are provided on both sides of the inner wall of the groove. The limiting rod 503 engages with the limiting slots 501. A second spring 509 is sleeved on the outer surface of the limiting rod 503. The two ends of the second spring 509 are fixedly connected to one side of the sliding plate 505 and one side of the inner wall of the cavity 507, respectively. A mounting bracket 512 is fixedly connected to one side of the connecting plate 2. A sliding hole is provided on one side of the mounting bracket 512, and a locking rod 511 is slidably connected within the sliding hole. The knob 515 has slots 510 around its perimeter, and the locking rod 511 engages with the slots 510. A second limiting plate 514 is fixedly connected to the outer surface of one end of the locking rod 511. One side of the second limiting plate 514 is in contact with one side of the knob 515. A third spring 513 is sleeved on the outer surface of the locking rod 511. Both ends of 513 are fixedly connected to one side of the mounting bracket 512 and one side of the second limiting plate 514, respectively. Multiple airbags 504 are fixedly connected to both sides of the inner wall of the cavity 507. The side of the airbag 504 away from the inner wall of the cavity 507 is fixedly connected to the side of the sliding plate 505. A sealing air ring 502 is fixedly connected to the outer side of the connecting plate 2. A connecting tube 508 is fixedly connected to one end of the airbag 504. The end of the connecting tube 508 away from the airbag 504 is fixedly connected to the side of the sealing air ring 502.

[0052] The specific implementation method is as follows: By setting the limiting sealing component 5, the operator rotates the knob 515, which drives the cam 506 to rotate. The cam 506 drives the limiting rod 503 to move to one side through the sliding plate 505, so that the limiting rod 503 and the limiting groove 501 are engaged with each other, realizing the fixed installation of the connecting plate 2 and the base 1. At the same time, the sliding plate 505 drives the airbag 504 to contract and transports the air in the airbag 504 to the sealing air ring 502 through the connecting pipe 508, so that the sealing air ring 502 expands and the sealing air ring 502 is tightly attached to the inner wall of the groove, realizing the replaceability of the cold source. In actual use, the cold source can be quickly replaced. At the same time, the sealing air ring 502 improves the sealing of the inside of the groove, preventing the cold air of the cold source from flowing out from the gap, thus extending the cooling time of the cold source and improving the cooling effect inside the first box 9 and the second box 11.

[0053] Working principle: During use, the operator places ice blocks into the ice storage tank 16, then pushes the ice storage tank 16 into the groove in the base 1. Next, the operator operates the limiting rod 503, separating it from the limiting groove 501. At this time, the operator rotates the knob 515, which drives the cam 506 to rotate via a shaft. The cam 506 moves the sliding plate 505 to one side, which in turn moves the limiting rod 503 to one side, causing the limiting rod 503 to engage with the limiting groove 501, ensuring proper connection. During the fixed installation of plate 2 and base 1, the sliding plate 505 drives the airbag 504 to contract. The airbag 504 contracts and transports the air inside the airbag 504 to the sealing ring 502 through the connecting pipe 508, causing the sealing ring 502 to expand and fit tightly against the inner wall of the groove. Afterward, the operator releases the limiting rod 503, and the third spring 513 drives the second limiting plate 514 to perform a reset movement. The second limiting plate 514 drives the limiting rod 503 to perform a reset movement, so that the limiting rod 503 and the limiting groove 501 are engaged with each other.

[0054] After placing the sample tube into the placement cylinder 14, the operator rotates the rotating ring 301. The rotating ring 301 drives the squeezing block 307 to rotate, which in turn drives the squeezing wheel 306 to move. The squeezing wheel 306 then drives the first limiting plate 302 to move, which in turn drives the sliding rod 304 to move. The sliding rod 304 then drives the bonding plate 305 to move, and the bonding plate 305 securely adheres to the sample tube. At this time, the limiting block 308 engages with the limiting hole 309 to prevent the rotating ring 301 from rotating back. Afterward, the bracket 13 is placed inside the first box 9 or the second box 11. After the specimen is placed inside, the door is closed, and the predetermined time is reached. The warning bell 8 reminds the sample to be sent for testing. During sample storage, the ice in the ice storage tank 16 provides a cold source. Cold air enters the first chamber 9 or the second chamber 11 through the pipe 15. At the same time, the motor 402 drives the rotating shaft to rotate, which in turn drives the rotating disk 404 to rotate. The rotating disk 404 drives the gear ring 405 to rotate, which in turn drives the transmission gear 407 to rotate. The transmission gear 407 drives the connecting shaft 406 to rotate, which in turn drives the sealing fan blade 409 to rotate. This changes the opening degree of the pipe 15, thereby changing the amount of cold air entering the first chamber 9 and the second chamber 11, and controlling the temperature inside the first chamber 9 and the second chamber 11.

[0055] Sensors and communication modules are also installed inside the first box 9 and the second box 11. The sensors and communication modules are connected to a microcontroller. When a specimen is placed in the specimen box and pushed in, the sensor detects the specimen and converts the signal into a digital signal through the signal conversion module, which then sends it to the microcontroller. After processing the information, the microcontroller issues an instruction message, which is then transmitted by the communication module to the terminal (mobile phone) of the transport worker. This can be done by sending a text message reminder or displaying the information on an app to proactively notify the transport worker to collect the sample for testing. If the sample is not delivered on time, the instruction message is sent to the transport worker's terminal again to remind them.

[0056] The aforementioned sensor is a camera, which is installed inside the top cover of the transport box and connected to the processing module. The instruction information can come from a barcode, that is, it is obtained by scanning the barcode affixed to the specimen by the camera. The operation method is that after the collector collects the specimen, he affixes the barcode with the pre-stored specimen information to the test tube or specimen bag, and the test tube or specimen bag is placed face up. The camera reads the information of the barcode, and after the information is processed by the processing center, it is sent to the terminal of the transport worker through the communication module.

[0057] The instruction information can include the specimen collection time, collection address, name of the collector, contact information of the collector, location of the testing center, and name of the receiving personnel at the testing center. Using a camera-based solution can meet the needs of many-to-many specimen transport, making it suitable for scenarios with multiple collection points and multiple testing centers. Because the information on the barcode is complete, transport personnel can know the specific transport route through the information received on the terminal.

[0058] Alternatively, it can connect via third-party software, such as the Dada APP. Upon detecting a sample signal, the communication module sends a transport order to the third-party software. The system then filters the data to identify the nearest transport personnel, who then collect the sample. This method is suitable for long-distance inter-hospital transport, where the collection point and testing center are typically not located within the hospital. For example, if the medical institution where the collection point is located lacks testing facilities, the sample needs to be sent to another medical institution for testing.

[0059] Infrared sensors are installed inside the first chamber 9 and the second chamber 11, one on each side. When a specimen is detected entering the first chamber 9 and the second chamber 11, the signal is converted into a digital signal by the signal conversion module and sent to the processing module. The processing module generates a prompt signal, which is then sent to the transport worker's terminal via the communication module. This method is suitable for point-to-point specimen transport, where the collection point and the testing center are clearly defined, and the prompt signal has a fixed standard format, such as a text message "Please come to collect your sample." This method is relatively simple because the transport personnel only need to travel back and forth between the fixed collection point and the testing center to collect the sample, eliminating the problem of multiple sampling locations and delivery to multiple locations.

[0060] In order to improve the convenience of transportation, handles can be provided on both sides of the box, or a transparent bag can be used to place the specimen storage and transportation box of the present invention inside the transparent bag. The opening of the transparent bag can be set as a sealed structure to play a waterproof role, and a handle can be provided on the top of the transparent bag.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
