Description

Technical Field

[0001] This invention relates to the field of hospital information reading technology, specifically to an RFID-based automated information reading device for hospital data collection tubes. Background Technology

[0002] During in vitro diagnostic testing, each sample needs to undergo blood collection tube holder confirmation, blood collection tube confirmation, and blood collection tube barcode scanning confirmation at each stage before proceeding to the next stage or process. This process involves a relatively long barcode scanning confirmation time. Because the blood collection tube is a tapered cylinder and the attached barcode has errors, it not only makes information reading inefficient but also easily causes track congestion.

[0003] Chinese patent CN209701684U discloses an automated sample information reading device based on RFID, including a collection tube, a tube rack, a guide rail body, an RFID carrier, and an RFID reader. The tube rack has a tube groove, and the collection tube is placed inside the groove to hold biological samples. An RFID carrier for storing biological sample information is located at the bottom inner side of the tube rack. A transmission structure is provided within the guide rail body, and the tube rack is placed within the guide rail body for automated transport via the transmission structure. An RFID reader for reading biological sample information from the RFID carrier is also located inside the guide rail body. In application, this device can effectively improve the sample information collection efficiency of biological sample diagnostic testing lines and solve the problem of track congestion in the testing line.

[0004] In practical use, the aforementioned patents fail to address the issue that when the RFID tag is misaligned, the RFID reader cannot read the tag properly, thus affecting the efficiency and accuracy of biological sample information collection. Therefore, they do not meet current requirements. To address this, we propose an RFID-based automated reading device for hospital collection tube information. Summary of the Invention

When the RFID tag is misaligned, preventing the RFID reader from reading the information, a third motor is activated to rotate the drive shaft, which in turn drives the drive gear. The drive gear rotates, causing the driven gear on the tube frame to rotate, thus rotating the tube frame and the RFID tag at the bottom of the tube frame until the RFID reader successfully reads the information on the RFID tag.

Detailed Implementation

[0041] 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.

[0042] To address the issue that in practical applications, when the RFID tag is misaligned, the RFID reader cannot properly read the RFID tag, thus affecting the efficiency and accuracy of biosample information collection, please refer to [link to relevant documentation]. Figures 1-10This embodiment provides the following technical solution:

[0043] The RFID-based automated reading device for hospital collection tubes includes a frame 1. A third conveying component 7 is located on one side of the front of the frame 1. A first conveying component 2 and a second conveying component 3 are located on the left and right sides of the frame 1, respectively. A feeding component 4 is located between the first conveying component 2 and the second conveying component 3 and is mounted on the frame 1. An RFID reader 8 is located at the bottom of the frame 1 at the conveying entrance of the third conveying component 7. A controller 5 is located on the outside of the frame 1 and has a display screen. A reading component 6 is located inside the frame 1. The reading component 6 is conveyed through the first conveying component 2, the second conveying component 3, and the third conveying component 7. The RFID reader 8 is used to automatically read the collection tube information. RFID technology enables non-contact identification through wireless transmission, and can track the specific information of the biological samples in the collection tube 61 in real time. After the collection tube 61 is tagged with an RFID tag, the information of the entire process from storage to use is automatically recorded. Medical staff can scan the tag to update the inventory, significantly reducing the error of manual inventory. By using the specific information of the biological samples in the collection tube 61, sample loss can be avoided.

[0044] The first conveying assembly 2 includes a mounting frame 21, an auxiliary roller 22, a limiting plate 23, a support platform 24, and a drive roller assembly 25. The mounting frame 21 is set on the inner walls of both sides of the frame 1. The auxiliary roller 22 is mounted on one of the mounting frames 21, and the limiting plate 23 is set directly above the auxiliary roller 22. The drive roller assembly 25 is mounted on the other mounting frame 21, and the support platform 24 is set on the mounting frame 21. The distance between the limiting plate 23 and the auxiliary roller 22 is matched with the thickness of the conveying plate 64 to limit the conveying plate 64 and prevent the collection tube 61 from sliding during transportation, which would cause the RFID carrier 65 to shift position and fail to be read normally.

[0045] The drive roller assembly 25 includes a chain 251, a connecting shaft 252, a drive gear 253, and a main roller 254. Multiple drive gears 253 are mounted on the chain 251. The drive gears 253 are fixed on the connecting shaft 252. The connecting shaft 252 is mounted on the main roller 254. The main roller 254 is rotatably mounted on the mounting frame 21 via the connecting shaft 252.

[0046] The first transmission component 2, the second transmission component 3, and the third transmission component 7 have the same structure. The first transmission component 2 and the second transmission component 3 are connected by the connecting component 26, and the third transmission component 7 is driven by the fourth motor 9.

[0047] The connecting assembly 26 includes a first motor 261, a first belt 262, a first pulley 263, a second pulley 264, and a second belt 265. The first belt 262 is mounted on a connecting shaft 252 on the drive shaft and the second transmission assembly 3 via the first pulley 263. The first pulley 263 is mounted on the connecting shaft 252 on the drive shaft and the second transmission assembly 3. The connecting shaft 252 closest to the second transmission assembly 3 is mounted on the second belt 265, which is mounted on the connecting shaft 252 on both the drive shaft and the first transmission assembly 2 via the second pulley 264. The second pulley 264 is mounted on the connecting shaft 252 on both the drive shaft and the first transmission assembly 2. One end of the drive shaft is installed at the output end of the first motor 261, and the other end is installed on the outer wall of the frame 1 through a bearing. When in use, the first motor 261 is started to make the drive shaft rotate, which drives the first pulley 263 and the second pulley 264 on the drive shaft to rotate, thereby driving the connecting shaft 252 on the first transmission assembly 2 and the connecting shaft 252 on the drive shaft and the second transmission assembly 3 to rotate, causing the drive gear 253 on the connecting shaft 252 to rotate, thereby driving the chain 251 to rotate, and then driving the remaining drive gear 253 to rotate. The rotation of the drive gear 253 drives the main roller 254 to rotate, thereby realizing the transmission of the reading assembly 6.

[0048] The feeding assembly 4 includes a second motor 41, a rotating shaft 42, a connecting rod 43, and a feeding rod 44. The output end of the second motor 41 is connected to the rotating shaft 42. The connecting rod 43 is fixed on the rotating shaft 42, and the feeding rod 44 is fixed at the bottom of the connecting rod 43. The second motor 41 is a forward and reverse motor. When in use, starting the second motor 41 causes the rotating shaft 42 to rotate, which in turn drives the connecting rod 43 to rotate forward and backward, so that the feeding rod 44 can feed the collection tube 61 to the first conveying assembly 2 or the second conveying assembly 3. The second motor 41 rotates forward to feed the collection tube 61 to the second conveying assembly 3, and the second motor 41 rotates in reverse to feed the collection tube 61 to the second conveying assembly 3.

[0049] The reading component 6 includes a collection tube 61, a tube frame 62, a limiting ring 63, a conveyor plate 64, an RFID carrier 65, an adjustment component 66, and a barcode 67. The collection tube 61 is installed inside the tube frame 62. The bottom of the tube frame 62 is equipped with an RFID carrier 65, and the limiting ring 63 is installed on the tube frame 62. The tube frame 62 is movably mounted on the conveyor plate 64, and a driven gear 68 is installed on the tube frame 62. The adjustment component 66 is installed on the lower surface of the conveyor plate 64. When reading the biological sample information in the collection tube 61, the collection tube 61 is placed inside the tube frame 62, and then the conveyor plate 64 is placed on the third conveyor component 7. At this time, the controller 5 controls the motors on multiple conveyor components to make multiple conveyor components rotate. When the tube frame 62 is conveyed between the first conveyor component 2 and the second conveyor component 3 through the third conveyor component 7, the conveyor plate 64 is located on the support platform 24. The RFID carrier 65 at the bottom of tube 2, which contains biological sample information, is read by the RFID reader 8. When the controller 5 receives the read information, it displays the specific information of the biological sample in the collection tube 61 on the display screen. It also controls the second motor 41 to rotate forward or backward according to the classification of the information, so that the tube rack 62 is transported to the first transmission component 2 and the third transmission component 7. This completes the reading and classification of the biological information in the collection tube 61, achieving the effect of classification and transmission based on the different information carried on multiple collection tubes. This avoids the need for manual classification after reading, which reduces the efficiency of information reading and can easily cause the production line to be blocked. By transmitting the read information to the control panel, the control panel displays the biological sample information in the collection tube 61 on the display screen, which facilitates the operator to observe and control the information reading process of the biological sample.

[0050] The adjustment assembly 66 includes a drive shaft 661, a third motor 662, and a drive gear 663. One end of the drive shaft 661 is mounted on the third motor 662, and the other end is rotatably mounted on the conveyor plate 64. The drive shaft 661 is equipped with a drive gear 663, which meshes with a driven gear 68 on the tube frame 62. In use, when the RFID tag 65 is misaligned, preventing the RFID reader 8 from reading the data, the third motor 662 is activated to rotate the drive shaft 661, which in turn drives the drive gear 663 to rotate. The rotation of the drive gear 663 drives the driven gear 68 on the tube frame 62 to rotate, causing the tube frame 62 to rotate. This causes the RFID tag 65 at the bottom of the tube frame 62 to rotate until the RFID reader 8 successfully reads the information on the RFID tag 65. This ensures that the RFID reader 8 can successfully read the information from the RFID tag 65, guaranteeing the accuracy of the information reading and effectively improving the efficiency of information reading.

[0051] The sampling tube sensing stabilization assembly includes a stabilizing frame 10, which is installed inside the tube frame 62 via several sets of fixed brackets 1025. The stabilizing frame 10 has several sets of clearance grooves 1012, and rotating bushings 1011 are correspondingly installed on the outer wall of the stabilizing frame 10 at each clearance groove 1012. A sector gear 1013 is installed on the rotating bushings 1011 via a drive shaft. A first connecting rod 1014 is fixedly installed on the side of the sector gear 1013 away from the tooth groove. A rubber pressure block 1015 is movably installed on the end of the first connecting rod 1014 away from the sector gear 1013. A test tube receiving bracket 1017 is located inside the stabilizing frame 10, and a second... The connecting rod 1019 is movably connected to the stabilizer 10. A return spring 1018 is sleeved on the outer wall of the second connecting rod 1019, and both ends of the return spring 1018 are fixedly connected to the test tube receiving bracket 1017 and the top of the inner wall of the stabilizer 10, respectively. Several sets of L-shaped brackets 1016 are arranged around the outer wall of the stabilizer 10, and each set of L-shaped brackets 1016 corresponds to a set of clearance grooves 1012. The horizontal end of the L-shaped bracket 1016 is fixedly connected to the pressure-bearing base 1023. A rack 1022 is installed on the side of the vertical section of the L-shaped bracket 1016 near the stabilizer 10. The rack 1022 meshes with a sector gear 1013. The top center of the pressure-bearing base 1023... A positioning ring seat 1024 is fixedly provided to cooperate with the second connecting rod 1019. The bottom of the inner wall of the tube rack 62 extends downward to form a receiving groove 1020. A second return spring 1021 is installed in the receiving groove 1020. The two ends of the second return spring 1021 are fixedly connected to the inner wall of the receiving groove 1020 and the bottom of the pressure base 1023, respectively. When the collection tube 61 is placed on the test tube receiving bracket 1017 in the stabilizer 10, under the action of the weight of the collection tube 61, the test tube receiving bracket 101 moves downward and pushes the second connecting rod 1019 into the positioning ring seat 1024, and the first return spring 1018 is compressed, which in turn continues to push the pressure base 1023 to move downward. At this time, the pressure base 1023 is engaged with the second connecting rod 1019. Several sets of L-shaped brackets 1016 connected to 1023 move downwards synchronously, causing the rack 1022 to drive the sector gear 1013 to rotate. While the sector gear 1013 rotates, it drives the rubber pressure block 1015 to move towards the outer wall of the collection tube 61 through the first connecting rod 1014 until it is in contact with the collection tube 61 and then it is tightened to prevent the collection tube 61 from changing position or tipping over during the movement, thus improving safety. In this way, the reading component 6 can be adapted to any size collection tube 61, and the tightening force of the several sets of rubber pressure blocks 1015 on the collection tube 61 will increase with the increase of its mass, greatly improving practicality.

[0052] It also includes a monitoring module, which includes:

[0053] A stepper motor encoder is integrated on the output shaft end of the third motor 662 and is used to collect the pulse signal of the rotation of the third motor 662;

[0054] A laser displacement sensor is installed on the upper surface edge of the conveyor plate 64 (outside the tube rack placement area), and is vertically aligned with the outer wall of the limiting ring 63 on the tube rack 62;

[0055] Several sets of speed sensors are respectively installed at the drive roller connecting shaft 252 end of the first conveying component 2 and the drive roller connecting shaft 252 end of the second conveying component 3, for detecting the rotational speed of the connecting shaft 252;

[0056] The controller and alarm are both installed on the outer wall of the frame 1;

[0057] The controller is electrically connected to the stepper motor encoder, laser displacement sensor, speed sensor, and alarm, respectively. The controller operates based on the stepper motor encoder, laser displacement sensor, speed sensor, and alarm, and includes:

[0058] Step 1: The controller calculates the code reading status index of this device based on the detection values ​​of the stepper motor encoder, laser displacement sensor, and speed sensor, and Formula 1:

[0059] (one)

[0060] in, This is the code reading status index of this device (quantifying the working status of the RFI code reading link). This refers to the number of successful read signals output by the RFID reader per unit time. This represents the total number of RFID code reads by the reader per unit time. The actual number of adjustment steps for the third motor 662 is obtained based on the stepper motor encoder detection. This represents the maximum allowable number of adjustment steps for the third motor 662. The actual deviation between the limiting ring 63 and the reference of the conveyor plate 64 is based on the value detected by the laser displacement sensor. This is the maximum permissible deviation of the limiting ring 63;

[0061] Step 2: The controller calculates the cooperative state index transmitted by this device based on Formula 2:

[0062] (two)

[0063] in, This is the transmission coordination status index of this device. The actual linear velocity (transmission speed of the acquisition tube) of the first transmission component 2 is obtained based on the speed sensor. The actual linear velocity acquisition tube of the second transmission component 3 is used to obtain the transmission speed based on the speed sensor. The reference transmission speed for the device design, The timestamp for the successful read signal output by the RFID reader. This is the timestamp for when the second motor 41 starts rotating. This is the maximum permissible trigger delay for the feeding component 4.

[0064] Formula (1) is expressed as follows: The weighting coefficients of 0.6, 0.3, and 0.1 are set based on the functional logic of "accurate code reading as the core, efficient adjustment as an auxiliary, and stable limit as the foundation." It represents the number of successful read signals output by the RFID reader per unit of time. It is the total number of code readings (successful + failed) by the reader within the same period, and the ratio of the two reflects the accuracy of the code reading; It is the actual number of adjustment steps of the third motor in the adjustment assembly, measured by the motor's integrated encoder. This is the maximum allowable number of adjustment steps for the third motor, calculated from the transmission ratio between the driving gear and the driven gear of the tube frame, and the motor step angle. Reflects regulatory efficiency; It is the actual deviation between the pipe rack limit ring and the conveyor plate reference, which is measured by a laser displacement sensor installed on the conveyor plate. This is the maximum permissible deviation of the limit ring. Reflecting the stability of the limit, ultimately The working status of the code reading process is quantified by weighted summation of the three factors: 0 represents the worst, 1 represents the best, and ≤0.5 triggers a fault alarm. This is used to solve the problem that the code reading status cannot be quantified and can provide early warning of problems such as inaccurate code reading, adjustment stagnation, and limit offset.

[0065] Formula (II) is expressed as follows: The weighting coefficients of 0.4, 0.3, and 0.3 are based on the original document's process logic of "synchronous transmission as the core, timely material allocation as the key, and code reading status as the prerequisite." It is the actual linear velocity of the first transmission component. This refers to the actual linear velocity of the second conveyor component, both of which are measured by a speed sensor on the connecting shaft of the drive roller of the corresponding conveyor component. This is the rated linear speed of the transmission component. Reflects transmission synchronization; It is the timestamp of the RFID reader outputting a successful read signal, which is collected by the reader's built-in timestamp module. This is the timestamp of the second motor starting to rotate in the feeding assembly, collected by the motor's integrated encoder time module. This is the maximum allowable trigger delay of the material feeding component. Reflects the timeliness of material allocation; It is the read status index calculated by Formula 1, reflecting the prerequisite role of read code in transmission coordination, and ultimately... The collaborative status of the entire process of "code reading-material allocation-transfer" is quantified by weighted summation of the three factors. 0 represents the worst and 1 represents the best. When the value is ≤0.5, a fault alarm is triggered, which solves the problem of unquantifiable original file transmission congestion and material allocation delay, and ensures efficient operation of the entire process.

[0066] Working principle: When using the RFID-based automated reading device for hospital information collection tubes of this invention, according to... Figures 1-8 This includes the following steps:

[0067] Step 1: When reading the biological sample information in the collection tube 61, place the collection tube 61 in the tube rack 62, and then place the transfer plate 64 on the third transfer component 7.

[0068] Step 2: Start the fourth motor 9, so that the third conveying component 7 conveys the collection tube 61 on the conveying plate 64. At the same time, start the first motor 261 to make the drive shaft rotate, which drives the first pulley 263 and the second pulley 264 on the drive shaft to rotate, which in turn drives the connecting shaft 252 on the first conveying component 2 and the connecting shaft 252 on the drive shaft and the second conveying component 3 to rotate, which makes the drive gear 253 on the connecting shaft 252 rotate, which in turn drives the chain 251 to rotate, which in turn drives the remaining drive gear 253 to rotate. The rotation of the drive gear 253 drives the main roller 254 to rotate, so that the first conveying component 2 and the second conveying component 3 can work.

[0069] Step 3: When the tube rack 62 is transferred between the first transfer component 2 and the second transfer component 3 via the third transfer component 7, the transfer plate 64 is located on the support platform 24. The RFID carrier 65 containing biological sample information installed at the bottom of the tube rack 62 will be read by the RFID reader 8 at the bottom of the tube rack 62, and the specific information of the biological sample will be displayed on the display screen on the controller 5.

[0070] Step 4: The controller 5 controls the second motor 41 to rotate forward or backward according to the classification of information, so that the rotating shaft 42 rotates, thereby driving the connecting rod 43 to rotate forward or backward, so that the feeding rod 44 can push the collection tube 61 to the first conveying component 2 or the second conveying component 3. The second motor 41 rotates forward to push the collection tube 61 to the second conveying component 3, and the second motor 41 rotates backward to push the collection tube 61 to the second conveying component 3, so that the tube rack 62 is conveyed to the first conveying component 2 and the third conveying component 7, completing the reading and classification of biological information in the collection tube 61;

[0071] Step 5: When the RFID carrier 65 is misaligned, preventing the RFID reader 8 from reading the information, the third motor 662 is started to rotate the drive shaft 661, which in turn drives the drive gear 663 to rotate. The rotation of the drive gear 663 drives the driven gear 68 on the tube frame 62 to rotate, causing the tube frame 62 to rotate. This causes the RFID carrier 65 at the bottom of the tube frame 62 to rotate until the RFID reader 8 successfully reads the information on the RFID carrier 65.

[0072] In summary, the RFID-based automated reading device for hospital collection tubes of the present invention controls the second motor 41 to drive the connecting rod 43 to rotate forward or backward according to the classification of information. This allows the feeding rod 44 to move the collection tube 61 onto the first conveying component 2 or the second conveying component 3. The second motor 41 moves forward to move the collection tube 61 onto the second conveying component 3, and vice versa, thus completing the reading and classification of biological information within the collection tube 61. This achieves the effect of classifying and transmitting information based on the different information carried by multiple collection tubes, avoiding manual classification after reading, which reduces information reading efficiency and can easily cause blockages in the production line. By transmitting the read information to the control panel, the control panel then... The biological sample information is displayed on the screen, facilitating the operator's observation and control of the biological sample information reading process. When the RFID carrier 65 is misaligned, preventing the RFID reader 8 from reading the information, the third motor 662 is activated, causing the drive shaft 661 to rotate. This, in turn, drives the drive gear 663 to rotate. The rotation of the drive gear 663 drives the driven gear 68 on the tube rack 62 to rotate, causing the tube rack 62 to rotate. This causes the RFID carrier 65 at the bottom of the tube rack 62 to rotate until the RFID reader 8 successfully reads the information on the RFID carrier 65. This ensures the accuracy of the information reading and effectively improves the efficiency of information reading.
