Description

Technical Field

[0001] This utility model relates to the field of blood collection tube cap devices, specifically an intelligent identification type blood collection tube cap device. Background Technology

[0002] In clinical testing, blood centers, and research laboratories, a manual verification process is adopted to standardize the use of blood collection tube caps. This involves medical staff visually identifying the color, label text, or shape of the cap (e.g., purple caps correspond to EDTA anticoagulant tubes, and red caps correspond to ordinary serum tubes) and manually matching them in accordance with operating procedures.

[0003] However, in the actual scenarios of clinical testing and sample management, visual fatigue caused by high-intensity repetitive work is the primary hidden danger. When medical staff need to continuously check a large number of blood collection tubes, their visual sensitivity will decrease, and the error rate of identifying color depth (such as the subtle difference between light purple and red), text clarity (such as the blurring of handwritten labels due to repeated erasing), and cap shape characteristics will increase. It is very easy to misuse different types of caps. Moreover, in high-time-sensitive scenarios such as emergency treatment, medical staff are easily forced to simplify the verification process in order to save golden treatment time (such as relying solely on color matching and ignoring secondary confirmation of text labels). Although this experience-based operation can shorten the time spent on a single operation, it makes the risk of cap misuse increase exponentially, directly leading to serious consequences such as sample contamination and deviation of test results. Therefore, we propose an intelligent identification blood collection tube cap device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide an intelligent identification blood collection tube cap device. This addresses the primary concern in current clinical testing and sample management scenarios where visual fatigue caused by high-intensity repetitive work is a major hidden danger. When medical staff need to continuously check a large number of blood collection tubes, their visual sensitivity decreases, increasing the error rate in identifying color depth (such as subtle differences between light purple and red), text clarity (such as blurred strokes on handwritten labels due to repeated erasing), and cap shape features. This makes it easy to misuse different types of caps. Moreover, in time-sensitive scenarios such as emergency treatment, medical staff are often forced to simplify the verification process to save precious time (such as relying solely on color matching while ignoring secondary confirmation of text labels). While this experience-based operation can shorten the time spent on a single test, it exponentially increases the risk of cap misuse, directly leading to serious consequences such as sample contamination and deviations in test results.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a smart identification blood collection tube cap device is designed, including a device housing, a cover plate is installed at the rear end of the device housing, multiple fixing blocks are installed at the bottom inside the device housing, the top of the multiple fixing blocks is provided with limiting grooves, multiple blood collection tubes with caps of different colors are placed in different limiting grooves, the inner wall of the limiting groove is provided with an installation groove, the installation groove is provided with a moving component, and a smart identification component is provided at the top of the device housing.

[0006] Preferably, the moving component includes a conveyor belt located in the mounting groove. A first rotating roller and a second rotating roller are respectively connected to the two ends of the conveyor belt. A drive motor is connected to the top of the first rotating roller through a fixed block. The drive motor is mounted on the top of the fixed block.

[0007] Preferably, the second rotating roller is connected to bearings at both its upper and lower ends, and the bearings are installed in the mounting groove.

[0008] Preferably, a circular groove is provided at the bottom of the limiting groove, a telescopic cylinder is installed inside the circular groove, and a piston rod is connected to the top of the telescopic cylinder.

[0009] Preferably, the intelligent identification component includes a fixed plate, and a plurality of RFID readers are mounted on one end surface of the fixed plate. The RFID readers are used to identify the RFID chip inside the cover.

[0010] Preferably, the front end of the device housing is provided with an industrial control computer, the surface of the industrial control computer is provided with multiple buttons corresponding to start the surface drive motors of different fixed blocks, and the top of the device housing is provided with multiple through holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model combines a fixing block, a limiting groove, and a moving component to place multiple blood collection tubes with caps of different colors into multiple limiting grooves. When different types of blood collection tubes are needed, the operator can use the buttons on the industrial control computer surface corresponding to the multiple blood collection tube types to start the drive motors on the corresponding fixing blocks, thereby driving the corresponding blood collection tubes to move and rise, so that the corresponding blood collection tubes can be directly moved out, making it convenient for the operator to accurately pick up different types of blood collection tubes.

[0013] 2. This utility model combines a fixed plate and an RFID reader. After the blood collection tube and the cap extend from the through hole, the RFID reader on the surface of the fixed plate can detect the RFID chip installed inside the cap. By reading the chip information (such as the cap model, production batch, and applicable testing items), the information is verified and displayed on the screen of the industrial control computer. This allows staff to quickly confirm the information and achieves intelligent identification of the cap information. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A smart identification blood collection tube cap device, see [link to example]. Figures 1 to 4The device includes a housing 1, with a cover plate 101 installed at the rear end. Multiple fixing blocks 211 are installed at the bottom inside the housing 1. Each fixing block 211 has a limiting groove 202 on its top. Multiple blood collection tubes 201 with different colored caps are placed in different limiting grooves 202. The inner wall of the limiting groove 202 has an installation groove 203. The installation groove 203 has a moving component inside. The top of the housing 1 is equipped with an intelligent recognition component. In the initial state, multiple blood collection tubes with different colored caps are placed in the multiple limiting grooves 202 preset on the device. When the staff needs to use a specific type of blood collection tube, they issue a command by operating the buttons on the surface of the industrial control computer 102 that correspond one-to-one with the various blood collection tube types. After receiving the command, the industrial control computer 102 will quickly identify and locate the fixing block 211 corresponding to the selected blood collection tube type. Subsequently, the industrial control computer 102 sends a start signal to the drive motor installed on the fixed block 211. Upon receiving the signal, the drive motor starts operating, and its output shaft drives the connected first rotating roller 205 to rotate. The rotation of the first rotating roller 205 drives the conveyor belt 207 surrounding it. Since the blood collection tube 201 is located between multiple conveyor belts 207, the friction generated by the movement of the conveyor belts 207 is transmitted to the blood collection tube, causing it to move along a predetermined direction. Under the continuous action of the conveyor belts 207, the target blood collection tube is moved to a position directly below the through hole 2. At this time, the telescopic cylinder 209 corresponding to the blood collection tube is activated. The piston inside the telescopic cylinder 209 pushes the piston rod 210 upward under pressure. As the piston rod 210 moves upward, the blood collection tube is pushed upward, passing through the through hole 2 and directly out of the device. The operator can easily and accurately obtain the blood collection tube. The efficient and precise selection of blood collection tubes significantly improves the efficiency and accuracy of tube selection. It addresses the primary concern in clinical testing and sample management: visual fatigue caused by repetitive, high-intensity work. When medical staff need to continuously check large numbers of blood collection tubes, their visual sensitivity decreases, increasing the error rate in identifying subtle differences in color (such as the difference between light purple and red), text clarity (such as blurred strokes on handwritten labels due to repeated erasing), and cap shape. This makes it easy to misuse different types of caps. Furthermore, in time-sensitive scenarios such as emergency situations, medical staff may be forced to simplify the verification process to save precious time (e.g., relying solely on color matching while ignoring secondary confirmation of text labels). While this experience-based approach may shorten the time spent per test, it exponentially increases the risk of cap misuse, directly leading to serious consequences such as sample contamination and test result deviations.

[0021] For details, see Figure 3The moving component includes a conveyor belt 207, which is located inside the mounting trough 203. The two ends of the conveyor belt 207 are respectively connected to a first rotating roller 205 and a second rotating roller 206. The top of the first rotating roller 205 passes through the fixed block 211 and is connected to a drive motor 204, which is mounted on the top of the fixed block 211.

[0022] Further, see Figure 3 The second rotating roller 206 has bearings connected to both its upper and lower ends, and the bearings are installed in the mounting groove 203.

[0023] It is worth noting that, see Figure 4 The bottom of the limiting groove 202 is provided with a circular groove 208, and a telescopic cylinder 209 is installed inside the circular groove 208. A piston rod 210 is connected to the top of the telescopic cylinder 209.

[0024] It is worth noting that, see Figure 1 The intelligent identification component includes a fixed plate 3. Multiple RFID readers 301 are mounted on one end surface of the fixed plate 3. The RFID readers 301 are used to identify the RFID chip inside the cap. When the blood collection tube and the cap extend from the through hole 2, the cap enters the effective identification range of the RFID readers 301 on the surface of the fixed plate 3. The RFID readers 301 on the surface of the fixed plate 3 emit electromagnetic waves of a specific frequency. When the cap enters its electromagnetic field coverage area, the RFID chip inside the cap is activated by electromagnetic induction. The activated RFID chip transmits its stored information, such as the cap model, production batch, and applicable testing items, by modulating the electromagnetic waves. The reflected signals are sent back to the RFID reader 301. After receiving these reflected signals, the RFID reader 301 demodulates them to restore the original information stored in the chip. The RFID reader 301 then transmits the chip information it reads to the connected industrial control computer 102 via wired or wireless means. After receiving the data from the RFID reader 301, the industrial control computer 102 further processes and analyzes it, and then displays the processed information, such as the cap model, production batch, and applicable testing items, on the screen of the industrial control computer 102. This allows the staff to quickly and intuitively see the cap-related information and perform secondary confirmation to ensure the accuracy and applicability of the cap information.

[0025] It is worth mentioning that, see Figure 1 The front end of the device housing 1 is provided with an industrial control computer 102. The surface of the industrial control computer 102 is provided with multiple buttons corresponding to the motors 204 driven by different fixed blocks 211. The top of the device housing 1 is provided with multiple through holes 2.

[0026] It should be noted that in this application, the multiple drive motors on a single fixed block 211 are controlled by a synchronous controller. The synchronous controller is an Omron SYSMAC CS1W-SCU31-V1 synchronous controller, which realizes the accuracy and stability of the coordinated operation of multiple drive motors on a single fixed block 211.

[0027] The RFID reader 301, model Alien ALR-H450, employs advanced radio frequency technology and antenna design, offering excellent read range and accuracy. It can identify RFID tags of various materials and sizes, and has low requirements on the tag's reading orientation. Its intelligent signal processing capabilities effectively filter interference signals, improving identification accuracy.

[0028] When using a smart identification blood collection tube cap device, firstly, in the initial state, multiple blood collection tubes with caps of different colors are placed in multiple preset limiting grooves 202 on the device. When the staff needs to use a specific type of blood collection tube, they issue a command by operating the buttons on the surface of the industrial control computer 102 that correspond one-to-one with the various blood collection tube types. After receiving the command, the industrial control computer 102 will quickly identify and locate the fixing block 211 corresponding to the selected blood collection tube type. Subsequently, the industrial control computer 102 sends a start signal to the drive motor installed on the fixed block 211. After receiving the signal, the drive motor starts to run, and its output shaft drives the first rotating roller 205 connected to it to rotate. The rotation of the first rotating roller 205 will drive the conveyor belt 207 surrounding it to move. Since the blood collection tube 201 is between multiple conveyor belts 207, the friction generated by the movement of the conveyor belt 207 will be transmitted to the blood collection tube, thereby driving the blood collection tube to move in a predetermined direction. Under the continuous action of the conveyor belt 207, the target blood collection tube is moved to be located directly below the through hole 2. At this time, the telescopic cylinder 209 corresponding to the blood collection tube is activated. The piston inside the telescopic cylinder 209 pushes the piston rod 210 upward under pressure. As the piston rod 210 moves upward, the blood collection tube is pushed upward, passes through the through hole 2 and is directly removed from the device. The staff can easily and accurately obtain the required type of blood collection tube. The whole process is efficient and precise, greatly improving the efficiency and accuracy of blood collection tube selection. After the blood collection tube and the cap extend out of the through hole 2, the cap enters the RFID reader 3 on the surface of the fixed plate 3. The effective identification range of 01 is such that the RFID reader 301 on the surface of the fixed plate 3 emits electromagnetic waves of a specific frequency. When the cover enters its electromagnetic field coverage area, the RFID chip installed inside the cover is activated by electromagnetic induction. The activated RFID chip reflects its stored information, such as the cover model, production batch, and applicable testing items, back to the RFID reader 301 by modulating electromagnetic waves. After receiving these reflected signals, the RFID reader 301 demodulates them to restore the original information stored in the chip. The RFID reader 301 transmits the chip information it reads to the connected industrial control computer 102 via wired or wireless means. After receiving the data from the RFID reader 301, the industrial control computer 102 further processes and analyzes it, and then displays the processed information, such as the cover model, production batch, and applicable testing items, on the screen of the industrial control computer 102, so that the staff can quickly and intuitively see the relevant information of the cover and make secondary confirmation to ensure the accuracy and applicability of the cover information.
