Description

Technical Field

[0001] This invention relates to the field of specimen storage technology, specifically to an automated specimen storage box. Background Technology

[0002] Tuberculosis is a respiratory infectious disease that endangers human health. Sputum specimens are the gold standard for diagnosing tuberculosis, and their accurate collection and transportation are crucial for ensuring accurate diagnosis and timely treatment. Currently, in clinical practice, nurses still manually verify sputum and other specimens (such as stool samples). This traditional manual verification method has the following drawbacks: it increases the opportunity for nurses to come into contact with bodily fluids and sputum from patients, causing contamination; traditional specimen tables are on ordinary desktops, and patients place their specimens themselves, leading to disorganized specimens and increasing the risk of cross-infection; currently, laboratory barcodes are generally small, requiring careful reading and double verification, wasting nurses' time and increasing their workload; and manual verification is inevitably prone to errors. Therefore, we propose a storage box that can automatically store specimens, reducing the occurrence of specimen contamination. Summary of the Invention

[0017] As a preferred embodiment of the present invention: the controller controls the air compressor and the electric push rod to shut down after a delay.

[0018] As a preferred embodiment of the present invention: the display screen, barcode scanner, and printer are electrically connected to the controller, which is a PLC controller with communication function. The controller controls and is electrically connected to the intake fan, exhaust fan, air compressor, electric push rod, first motor linear module, second motor linear module, third motor linear module, electric gripper, fourth motor linear module, stainless steel pump, micro stepper motor, camera, and electromagnet. After the patient scans the barcode on the sample surface through the barcode scanner, the controller controls the electric push rod in the first or second baffle mechanism to work according to the sample information. After the patient places the sample in the corresponding first placement slot, the controller controls the first motor linear module, second motor linear module, third motor linear module, and electric gripper to pick up the sample and place it in the first placement slot on the surface of the placement tray. The controller then sends the patient's sample placement information to the doctor's information terminal.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The two specimen storage components enable the categorized storage of patient sputum and stool specimens. Patients scan the barcode on the surface of the specimen container. Since each specimen's barcode is unique, after the barcode scanner scans the barcode, the controller can control the electric push rod in the first or second baffle mechanism to lower the sealing plate, thereby opening the first or second opening. The corresponding specimen storage component corresponds to the corresponding first or second opening. Therefore, the patient places the specimen container in the corresponding first placement slot, and the specimen retrieval component can then place the patient's specimen into the second placement slot on the surface of the placement tray. At this time, the controller... The device sends the patient's specimen storage information to the doctor's terminal, where a patient specimen summary sheet can be generated. When medical staff retrieve the specimen, they scan the barcode on the specimen summary sheet. The controller then de-energizes the electromagnet, causing the micro stepper motor to drive the first door to open. The fourth motor linear module then pushes the placement tray into the storage cavity, making it easier for medical staff to retrieve the patient's specimen. This method ensures that the specimens are stored in an orderly manner and facilitates information verification by medical staff, reducing their workload. When the patient is storing the specimen, the air knife blows air downwards at an angle, creating an air curtain. At this time, external air cannot enter the storage cavity through the first and second openings, reducing the probability of sample contamination in the storage cavity. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 11This invention provides a technical solution: an automated specimen storage box, including a box body 1 and a touch screen display 2. The display screen 2 is installed on the top of the box body 1, and a camera 3 is installed on the top of the display screen 2. The camera 3 is used to capture specimen storage and retrieval operations. The box body 1 is divided into a storage cavity 4 and an equipment cavity 5 by a partition. Two specimen storage components 6 are installed in the storage cavity 4, arranged vertically. Different specimen storage components 6 are used to place different specimens to be tested. A disinfection tank 7 is placed in the equipment cavity 5. A disinfection component 8 is also installed in the storage cavity 4. The disinfection area of ​​the disinfection component 8 covers the storage cavity 4. A first box door 9 and a second box door 10 are respectively installed on the front of the box body 1 at the storage cavity 4 and the equipment cavity 5. A barcode scanner 11 and a printer 12 for scanning barcodes on the specimen surface are installed on the top of the front of the box body 1. The surface of the first box door 9 has a first opening 13 and a second opening 14. A first baffle mechanism and a second baffle mechanism are respectively installed at the first opening 13 and the second opening 14. Opening 13 and second opening 14 are respectively opposite to two specimen storage components 6. A first installation port penetrating the box body 1 is opened on one side inner wall of the storage cavity 4, and a second installation port penetrating the box body 1 is opened on the back inner wall of the storage cavity 4. An air intake fan 15 and an exhaust fan 16 are respectively installed in the first installation port and the second installation port. A first filter component 17 and a second filter component 18 are respectively installed at the first installation port and the second installation port. The air intake fan 15 and the exhaust fan 16, together with the first filter component 17 and the second filter component 18, form a circulating air duct in the storage cavity 4 and make the disinfectant sprayed by the disinfection component 8 evenly diffuse in the storage cavity 4. An air knife 19 is installed on the front of the box body 1 at the top of the first box door 9 and the second box door 10. The air knife 19 blows air at an angle downward to form an air curtain isolation. A controller and an air compressor 20 are also installed in the equipment cavity 5. The air compressor 20 is connected to the air knife 19. When storing different specimens, the controller controls the corresponding first baffle mechanism or second baffle mechanism to open the first opening 13 or the second opening 14.

[0024] In this embodiment, the first baffle mechanism and the second baffle mechanism have the same structure and are both composed of an electric push rod 21 and a sealing plate 22. The bottom of the first opening 13 and the second opening 14 are respectively provided with a first storage groove 23 and a second storage groove 24. The box body 1 is provided with a first mounting cavity 25 and a second mounting cavity 26 on one side of the first opening 13 and the second opening 14, respectively. The sealing plate 22 in the first baffle mechanism and the second baffle mechanism is respectively inserted into the first storage groove 23 and the second storage groove 24. The first opening 13 and the second opening 14 are both provided with guide grooves 27 that connect to the storage grooves. The sealing plate 22 is slidably installed on both sides. Within the guide groove 27, the first storage groove 23 and the second storage groove 24 are respectively connected to the first mounting cavity 25 and the second mounting cavity 26. The electric push rods 21 in the first baffle mechanism and the second baffle mechanism are respectively installed in the first mounting cavity 25 and the second mounting cavity 26. Connecting strips 28 are fixedly connected to one side of the bottom of the two sealing plates 22. The two connecting strips 28 extend into the corresponding first mounting cavity 25 and the second mounting cavity 26 and are respectively connected to the corresponding electric push rods 21. The top of the first opening 13 and the second opening 14 are respectively provided with a closed groove 29 that connects to the guide groove 27. Sealing strips are installed in both the guide groove 27 and the closed groove 29.

[0025] Specifically, the electric push rods 21 in the first and second baffle mechanisms can drive the corresponding sealing plates 22 to rise and fall in the first storage slot 23 and the second storage slot 24 respectively. In this way, the sealing plates 22 can seal the first opening 13 and the second opening 14. When the first opening 13 or the second opening 14 is open, the patient can put the specimen into the storage cavity 4 through the first opening 13 or the second opening 14 and arrange the patient's specimen in an orderly manner through the corresponding specimen storage components 6, thereby improving the neatness of specimen placement. Moreover, during the specimen placement process, the patient will not come into contact with other people's specimens, thereby reducing the risk of cross-infection. The installation of sealing strips in the guide groove 27 and the sealing groove 29 can improve the sealing performance with the sealing plates 22, thereby preventing external air from entering the storage cavity 4 through the gap between the guide groove 27, the sealing groove 29 and the sealing plates 22.

[0026] In this embodiment, the specimen storage component 6 consists of a specimen gripping component 61 and a specimen placement device 62. The specimen gripping component 61 includes a first motor linear module 611 installed on the inner wall of the back side of the storage cavity 4. The mover of the first motor linear module 611 is fixedly connected to a second motor linear module 612. The mover of the second motor linear module 612 is fixedly connected to a third motor linear module 613. An electric gripper 614 is installed on the mover of the third motor linear module 613. The specimen placement device 62 is installed at the bottom of the third motor linear module 613.

[0027] Specifically, the first linear motor module 611 can drive the second linear motor module 612 to move vertically along the Z-axis, the second linear motor module 612 can drive the third linear motor module 613 to move along the Y-axis, and the third linear motor module 613 can drive the electric gripper 614 to move along the X-axis. In this way, the electric gripper 614 can move along three axes, which makes it easier to grip and stack specimen containers.

[0028] In this embodiment, the specimen placement device 62 includes a fourth motor linear module 621 installed on the inner walls of both sides of the storage cavity 4. The movers of the two fourth motor linear modules 621 are arranged opposite to each other and the surfaces of the two modules are fixedly connected to a receiving plate 622. The sides of the two receiving plates 622 are fixedly connected to a limiting strip 623. One end of the receiving plate 622 is fixedly connected to a limiting block 624. A placement tray 625 is placed on the surface of the receiving plate 622. The limiting strips 623 are attached to both sides of the placement tray 625 and the limiting block 624 is attached to the tail end. A first placement groove 626 is provided at one corner of the placement tray 625. The surface of the placement tray 625 is also provided with a plurality of second placement grooves for placing specimens.

[0029] Specifically, the placement tray 625 can be positioned by the limiting strip 623 and the limiting block 624. The placement tray 625 is placed on the surface of the receiving plate 622 and limited by the limiting strip 623 and the limiting block 624, which facilitates the quick positioning of the placement tray 625 by the staff. The patient places the specimen container in the first placement slot 626, which is the initial placement position. At this time, the first motor linear module 611 and the second motor linear module 612 are in operation. The third motor linear module 613, in conjunction with the electric gripper 614, grips the specimen container placed in the first placement slot 626. Then, the electric gripper 614 places the gripped specimen container into the second placement slot on the surface of the placement tray 625. In this way, the patient's specimens can be placed in an orderly manner, and the patient will not come into contact with the specimens of other patients during this process, reducing the risk of cross-infection. After each patient scans the barcode, the specimen placement position is selected by the controller, so the doctor's terminal can also know the patient's specimen placement position.

[0030] In this embodiment, the disinfection component 8 includes a disinfection tube 81. Both ends of the disinfection tube 81 are sealed and fixed in the storage cavity 4 by pipe fixing components. The disinfection tube 81 is coiled and forms two annular spray zones 82 at the top and bottom. Two specimen storage components 6 are located between the two annular spray zones 82. An atomizing nozzle 83 is installed on the surface of the disinfection tube 81 at the annular spray zone 82. A three-way pipe 84 is also installed on the disinfection tube 81. One end of the three-way pipe 84 is connected to a first connecting pipe 85. The first connecting pipe 85 passes through a partition and is connected to the water outlet of a stainless steel pump 86. The water inlet of the stainless steel pump 86 is connected to a second connecting pipe 87. The second connecting pipe 87 is inserted into the disinfection tank 7.

[0031] Specifically, after medical staff remove all the placement trays 625 from the storage chamber 4, the storage chamber 4 is empty. At this time, medical staff can click the "Disinfection" button displayed on the display screen 2, and the controller will control the stainless steel pump 86 to extract the alcohol from the disinfection tank 7 and pump it into the disinfection tube 81 through the second connecting pipe 87, the first connecting pipe 85 and the three-way pipe 84. Since the disinfection tube 81 forms two annular spray zones 82 in the storage chamber 4 through the pipe fixing component, and the specimen storage component 6 is located between the two annular spray zones 82, the alcohol is sprayed out as an alcohol mist through the atomizing nozzle 83 to disinfect the storage chamber 4 and the specimen storage component 6. The air intake fan 15 and the exhaust fan 16 allow the air inside the storage chamber 4 to circulate with the outside air, which can promote the evaporation of alcohol and prevent alcohol residue on the surface of the storage chamber 4 and the specimen storage component 6 from causing damage to the parts.

[0032] In this embodiment, the surfaces of the placement trays 625 in the two specimen storage components 6 are at the same level as the bottom of the first opening 13 and the second opening 14, respectively, and the first placement grooves 626 on the surfaces of the two placement trays 625 are located at the first opening 13 and the second opening 14, respectively.

[0033] Specifically, when the first opening 13 or the second opening 14 is opened in this way, the first placement groove 626 on the surface of the placement tray 625 is directly opposite the first opening 13 or the second opening 14. At this time, the patient can easily place the specimen container into the first placement groove 626 through the first opening 13 and the second opening 14.

[0034] In this embodiment, two micro stepper motors 30 are installed on the front of the housing 1. The output shafts of the two micro stepper motors 30 are respectively connected to the rotating shaft of the first door 9. An electromagnet 31 for magnetically attracting the first door 9 is installed on the front of the housing 1.

[0035] Specifically, when medical staff need to retrieve the specimen stored in the storage chamber 4, they can click the "Retrieve Sample" button displayed on the screen 2. At this time, the controller controls the electromagnet 31 to de-energize and release the magnetic attraction on the first box door 9. Simultaneously, the controller controls the micro stepper motor 30 to work, so that the first box door 9 can be opened automatically. Then, the fourth motor linear module 621 drives the receiving plate 622 to move outward, thereby transporting the placement tray 625 to the outside of the storage chamber 4, which makes it easier for medical staff to retrieve the sample.

[0036] In this embodiment, the first filter assembly 17 includes a first mounting frame 171 installed at the first mounting port. A first filter screen 172, a non-woven filter cotton 173, and a second filter screen 174 are installed in the first mounting frame 171. The non-woven filter cotton 173 is disposed between the first filter screen 172 and the second filter screen 174. The second filter screen 174 is disposed on one side of the air intake fan 15. The diameter of the filter holes of the second filter screen 174 is smaller than the diameter of the filter holes of the first filter screen 172.

[0037] Specifically, the first filter 172, the non-woven filter cotton 173, and the second filter 174 can effectively filter dust and particles in the outside air, preventing dust from accumulating in the storage chamber 4.

[0038] In this embodiment, the second filter assembly 18 includes a second mounting frame 181 installed at the second mounting port. A HEPA filter 182 and an activated carbon filter layer 183 are installed in the second mounting frame 181. The activated carbon filter layer 183 is disposed on one side of the exhaust fan 16.

[0039] Specifically, the activated carbon filter layer 183 can adsorb the odor emitted by the specimens stored in the storage chamber 4, while the HEPA filter 182 can intercept and filter the microbial aerosols such as bacteria and viruses emitted by the specimens stored in the storage chamber 4, as well as fine particles, thereby preventing the spread of germs.

[0040] In this embodiment, a side plate 32 is installed on one side of the housing 1 located in the equipment cavity 5 by screws, and a universal wheel 33 with braking function is installed at the bottom of the housing 1.

[0041] Specifically, the side panel 32 facilitates maintenance of the components inside the equipment cavity 5, while the casters 33 facilitate movement of the storage box. The casters 33 also have a braking function, which improves the stability of the storage box during use.

[0042] Working principle: For example, sputum samples are placed in the upper placement tray 625 and stool samples are placed in the lower placement tray 625. When a patient needs to place a specimen, they first scan the barcode on the surface of the specimen container using the barcode scanner 11 (e.g., when placing a sputum sample). Since the barcode corresponding to the specimen is unique, after the patient clicks the "Place Sample" button displayed on the screen 2, the controller controls the electric push rod 21 in the first baffle mechanism to move the sealing plate 22 downward into the first storage slot 23. At this time, the first opening 13 opens, and the patient places the specimen container containing the sputum sample into the first placement slot 626 through the first opening 13. The first linear motor module 611 can drive the second linear motor module 612 vertically along the Z-axis direction. The second motor linear module 612 drives the third motor linear module 613 to move along the Y-axis, and the third motor linear module 613 drives the electric gripper 614 to move along the X-axis. This allows the electric gripper 614 to move along three axes, making it easier to grip and stack specimen containers. During this process, the controller controls the air compressor 20 to operate, causing the air knife 19 to blow air downwards at an angle, creating an air curtain. At this time, external air cannot enter the storage chamber 4 through the first opening 13, reducing the probability of sample contamination in the storage chamber 4. The controller also controls the air compressor 20 and the electric push rod 21 to close after a delay; that is, after the first opening 13 has been open for a certain period, the controller controls the air compressor 20 to stop working, and simultaneously controls the electric push rod 21 to close. Push rod 21 drives sealing plate 22 to seal the first opening 13. The delay time is determined by the staff. Inside storage cavity 4, specimen retrieval component 61 retrieves the specimen container in the first placement slot 626 and places it orderly in the second placement slot on the surface of placement tray 625. The camera 3 can monitor and record the patient's specimen storage, facilitating hospital record management. After the patient's specimen is stored, printer 12 prints a receipt for the patient to keep. After the patient scans the barcode, the controller transmits the patient information to the doctor's terminal. The doctor's terminal can generate a patient specimen summary sheet, which can be compared with the patient information uploaded to the doctor's terminal to quickly identify any missing specimens. Patient information is collected for specimen collection. Since the number of second placement slots on the surface of placement tray 625 is limited, a warning message will be generated at the doctor's terminal before the amount of specimen in the second placement slot reaches its limit, prompting the doctor to remove the sample and replace placement tray 625 promptly. When removing the sample, the doctor clicks the "Remove Sample" button displayed on the screen 2 and scans the barcode on the summary sheet using barcode scanner 11. At this time, the controller will de-energize electromagnet 31 and start micro stepper motor 30 to open the first door 9. The controller then controls the fourth motor linear module 621 to transport placement tray 625 to the outside of storage chamber 4, facilitating timely sample removal and replacement by staff. Afterwards, the staff clicks the "Reset" button displayed on the screen 2.This resets the specimen storage component 6, facilitating the orderly removal of specimen containers from the new placement tray 625. It's worth noting that the "reset" button is only usable when the first door 9 is open. If all placement trays 625 in the storage cavity 4 are removed and empty, a disinfection barcode is printed at the doctor's terminal. Staff then scan the barcode using the barcode scanner 11. At this point, the controller activates the disinfection component 8 to disinfect the storage cavity 4 and the specimen storage component 6. This storage box can automatically store patient specimens, reducing contact between patients and other specimens during storage and lowering the risk of cross-infection. Simultaneously, the information on the patient's stored specimens can be compared with that at the doctor's terminal, allowing for quick identification of patients without stored specimens. This process eliminates the need for double verification, effectively reducing staff workload, and this verification method is more efficient and error-free.
