Description

Technical Field

[0001] This invention relates to the field of blood testing, and in particular to a thromboelastography testing device based on visual detection. Background Technology

[0002] Thromboelastography, as a non-invasive diagnostic tool, assists doctors in assessing a patient's coagulation status by detecting and analyzing the entire process of blood clotting.

[0004] However, existing testing equipment cannot perform large-scale testing well, and cannot operate automatically, so a lot of manual intervention is required to complete the testing work. In addition, there is no monitoring function during operation, which makes it difficult to monitor whether the sample to be tested (blood sample) is correct, which may lead to errors in the test results. For example, the test result of Zhang San's blood sample may be changed to Li Si's. As a result, the machine's operational stability is not enough.

Detailed Implementation

[0064] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0065] Reference Figure 1-7As shown, a thromboelastography testing device based on visual inspection includes: a frame 10, an industrial control unit 20, a cup delivery unit 30, a sample delivery unit 40, a detection unit 50, a reagent unit 60, a sampling unit 70, a cap delivery unit 80, a cap removal unit 90, and a moving unit 100; a protective cover 101 is detachably mounted on the upper end of the frame 10; the industrial control unit 20 is detachably mounted on the protective cover 101; the cup delivery unit 30 carries an empty cup and can move the empty cup to the rear; the sample delivery unit 40 is installed on the right side of the cup delivery unit 30, and carries a sample cup with text labels and barcode labels. The sample cup can be moved backward; the detection unit 50 includes multiple sets of detection elements 501, and a set of detection elements 501 is installed on both the left and right sides of the sample delivery unit 40. One set of detection elements 501 is located between the cup delivery unit 30 and the sample delivery unit 40, and the detection elements 501 can recognize the text markings and barcode markings on the sample cup; the reagent unit 60 is located on the right side of the detection unit 50 and the sample delivery unit 40, and another set of detection elements 501 is installed between the sample delivery unit 40 and the reagent unit 60. The reagent unit 60 is loaded with calcium chloride reagent and can move backward; the sampling unit 70 is located on the rear side between the sample delivery unit 40 and the reagent unit 60. The sampling unit 70 can extend into the sample cup to take a sample and can take calcium chloride reagent; the cap delivery unit 80 is installed on the right side of the reagent unit 60. The cap delivery unit 80 is loaded with a cup cap and can move backward; the cap removal unit 90 is installed on the right side of the cap delivery unit 80 and can remove the cup cap; the moving unit 100 The cup feeding unit 30, sample feeding unit 40, detection unit 50, reagent unit 60, sampling unit 70, and cap removal unit 90 are installed on the rear side. The moving unit 100 is installed above the cap feeding unit 80. The moving unit 100, the feeding unit, the sample feeding unit 40, the detection unit 50, the reagent unit 60, the sampling unit 70, and the cap removal unit 90 are all installed on the platform (shown but not labeled in the figure) of the frame 10. The moving unit 100 is arranged along the length of the platform. The moving unit 100, the feeding unit, the sample feeding unit 40, the detection unit 50, the reagent unit 60, the sampling unit 70, the cap removal unit 90, and the cap feeding unit 80 are all electrically connected to the industrial control unit 20.

[0066] The aforementioned industrial control unit 20 includes a PLC and a touch panel, with the touch panel electrically connected to the PLC. The cup feeding unit 30, sample feeding unit 40, detection unit 50, reagent unit 60, sampling unit 70, cap feeding unit 80, cap removal unit 90, and moving unit 100 are all electrically connected to the PLC. The aforementioned detection unit 50 being electrically connected to the PLC can be understood as the detection element 501 being electrically connected to the PLC.

[0067] Specifically, refer to Figure 3As shown, the industrial control unit 20 sends a command to start the cup-feeding unit 30, causing the empty cup to move towards the moving unit 100, so that the moving unit 100 can obtain the empty cup. (Refer to...) Figure 4 As shown, the detection unit 501 identifies the text and barcode markings on the sample cup. Specifically, the detection unit 501 uses OpenCV OCR to recognize the text and QR code markings on the sample cup, ultimately identifying the barcode information on the sample bottle. When the barcode information matches the text markings, the detection unit 501 uploads this information to the PLC and displays the blood sample owner's information on the touch panel for the operator to select; this can be understood as the name of the person to be tested. For more details, please refer to... Figure 4 As shown, the operator selects the name of the person to be tested on the touch panel. The PLC sends a command to drive the sample delivery unit 40 to move towards the sampling unit 70, allowing the sampling unit 70 to obtain a blood sample from the sample cup. Simultaneously, the moving unit 100, which obtains an empty cup, moves the empty cup to the rear of the sample delivery unit 40, so that the sampling unit 70, which has obtained the blood sample, can transfer the blood sample to the empty cup of the moving unit 100. (Refer to...) Figure 5 As shown, the moving unit 100 drives the empty blood sample cup obtained in the above-mentioned process to the rear of the reagent unit 60, and the sampling unit 70 further obtains the calcium chloride reagent from the reagent unit 60, and injects the calcium chloride reagent into the empty cup to mix and react with the blood sample cup. (Refer to...) Figure 7 As shown, the PLC sends a command to drive the cap feeding unit 80 to work. The cap feeding unit 80 drives the empty cup to move toward the cap taking unit 90, so that the cap taking unit 90 can take the cup cap downwards. After the cap taking unit 90 takes the cup cap, it resets upwards. The moving unit 100 drives the empty cup containing calcium chloride reagent and blood sample cup to move toward the cap taking unit 90, so that the cup cap on the cap taking unit 90 can fall off and the cup cap can be put into place with the sample cup cap.

[0068] In addition, by setting up the detection component 501, errors in the test results of blood samples can be effectively avoided, unlike traditional equipment. This effectively ensures the stable operation of the equipment and improves the accuracy of blood sample testing.

[0069] It should be noted that the detection component 501 can be an industrial camera with character recognition (OpenCV OCR) and barcode recognition in specific implementations. In this implementation, an industrial camera with character recognition and barcode recognition functions that is already available on the market can be used. Therefore, no changes are made to its functions in this implementation, and the detection component 501 is electrically connected to the PLC.

[0070] Furthermore, the number of detection units 50 mentioned above is not limited by the present invention. Those skilled in the art can add detection units 50 to each unit of the device according to actual needs, so that the device can further perform visual inspection of the device during operation.

[0071] Furthermore, the cup feeding unit 30 includes a conveyor 301, side plates 302, a cover plate 303, a channel plate 304, and a cup holder 305. The conveyor 301 is fixedly installed on the upper part of the platform of the frame 10 via a supporting base plate and two sets of support plates. The conveyor 301 has a gap with the platform in the height direction, and a set of side plates 302 can be detachably installed on both the left and right ends of the conveyor 301. Each side plate 302 is higher than the conveyor 301 in the height direction. The cover plate 303 is detachably installed on the upper part of the two sets of side plates 302. The channel plate 304 consists of three sets detachably installed on the lower part of the cover plate 303, and there is a gap between the three sets of channel plates 304, forming a channel for the cup holder 305 to pass through. All three sets of channel plates 304 have gaps with the conveyor 301, and two sets of channel plates 304 also have gaps with the two sets of side plates 302. The cup holders 305 are detachable and can be arranged in multiple arrays within a channel. Each array of cup holders 305 is placed within a conveyor 301, and each cup holder 305 holds an empty cup. There is a height gap between the empty cup and the conveyor 301. The array of cup holders 305 can be driven by the conveyor 301 to move towards the moving unit 100. The detachable installation method can be, for example, using bolts or other connection methods.

[0072] Specifically, please refer to the detailed information. Figure 3 As shown, the movement of the conveyor 301 causes the empty cup to move toward the moving unit 100, so that the moving unit 100 can obtain the empty cup. Then, the moving unit 100 drives the empty cup obtained from the conveyor 301 to move toward the detection unit 50.

[0073] It should be noted that the conveyor 301 in this embodiment can be a combination of a motor (not shown in the figure) and a belt conveyor driven by the motor. The activation of the cup-feeding unit 30 mentioned above, causing the empty cup to move towards the moving unit 100, can be understood as the empty cup being placed on the conveyor belt of the belt conveyor. The belt conveyor mentioned above can be driven by a motor; of course, the connection method between the two in this embodiment adopts existing conventional methods, which will not be elaborated further here.

[0074] Furthermore, the sample delivery unit 40 includes a first linear motor module 401 and a tray 402 fixed thereon; the first linear motor module 401 is fixedly installed along the width direction of the platform and is located on one side of the detection unit 50; the upper end of the tray 402 is provided with a plurality of blind holes for placing sample cups, the number of sample cups is adapted to the number of the plurality of blind holes, the tray 402 is located between the two sets of detection pieces 501, and the first linear motor can drive the tray 402 to move along the width direction of the frame 10.

[0075] Specifically, please refer to the detailed information. Figure 2 , 4 As shown, the PLC sends a command to activate the first linear motor module 401, which in turn moves the tray 402, causing the sample cup on the tray 402 to move along with it. The movement of the tray 402 can be understood as the tray 402 moving along the width of the platform, or as the tray 402 moving towards the sampling unit 70, allowing the sampling unit 70 to obtain the blood sample from the sample cup. In other words, the sample cup moves with the tray 402 to below the sampling unit 70. (Refer to...) Figure 4 As shown, the empty cup moving unit 100 drives the empty cup to move to the rear of the sample delivery unit 40, and the blood sample collection unit 70 delivers the blood sample to the empty cup on the moving unit 100.

[0076] It should be noted that the first linear motor module 401 in this embodiment includes at least a servo motor and a ball screw fixedly connected to the output shaft of the servo motor. The first linear motor module 401 and the support plate 402 fixed thereon mentioned above should be understood by those skilled in the art as being fixed to the screw nut of the ball screw; similarly, the servo motor should be understood as being electrically connected to the PLC. The first linear motor module 401 mentioned above in this embodiment includes, but is not limited to, a servo motor, a ball screw, and a screw nut; it may also include a side cover plate 303 and an end cover plate 303, etc.

[0077] Furthermore, the detection unit 50 also includes a fixing frame 502; the fixing frame 502 consists of two sets fixedly installed on the platform, each fixing frame 502 being higher than the sample cup in the height direction, and each fixing frame 502 is fixedly installed with a set of detection elements 501, the detection elements 501 being tilted towards the sample cup and capable of recognizing the text and barcode markings on the sample cup.

[0078] Specifically, refer to Figure 2 , 4 As shown, by setting the fixing frame 502, the detection component 501 can be installed on it, and the detection component 501 can be tilted towards the sample cup on the fixing frame 502. That is, it can also be understood that the imaging end of the detection component 501 is tilted towards the sample cup.

[0079] Further, the reagent unit 60 includes side plates 601, a transport component 602, a top plate 603, and a passage plate 604; the side plates 601 are in two sets, fixedly installed on the upper end of the platform; a set of side plates 601 can be detachably installed on both the left and right ends of the transport component 602, and there is a gap between the transport component 602 and the platform in the height direction, and the two sets of side plates 601 are higher than the upper end surface of the transport component 602 in the height direction; the top plate 603 is detachably installed on the upper end of the two sets of side plates 601; the passage plate 604 is in three sets, the upper ends of the three sets of passage plates 604 are detachably installed on the lower end of the top plate 603 and located between the two sets of side plates 601, and the lower ends of the three sets of passage plates 604 are connected to the transport component 602. The passageway is formed by gaps between the plates 604 and the gaps between the plates 604. The reagent cups are arranged in multiple arrays in the passageway. Each reagent cup (shown but not labeled in the figure) contains calcium chloride reagent. The lower end of the reagent cup is placed on the transport member 602, so that the transport member 602 can be driven to move toward the taking unit 70 and the moving unit 100.

[0080] Specifically, referring to Figures 2 and 5, the PLC sends a command to the conveyor 602 to move the reagent cup toward the moving unit 100. Similarly, see details... Figure 5 As shown, the PLC sends a command to the sampling unit 70 to move toward the reagent cup and obtain the calcium chloride reagent in the reagent cup. The sampling unit 70 then moves the obtained calcium chloride reagent toward the moving unit 100 and injects the calcium chloride reagent into the sample cup. Of course, those skilled in the art should understand that the sample cup at this time contains calcium chloride reagent and blood sample, and when the sampling unit 70 moves to obtain the calcium chloride reagent, the transport component 602 stops working.

[0081] It should be noted that the structure of the conveying component 602 is the same as that of the conveying component 301 in the specific implementation, and the motor on the conveying component 602 is electrically connected to the PLC.

[0082] Furthermore, the acquisition unit 70 includes a mounting plate (shown in the figure but not labeled), a first acquisition element 701, and a second acquisition element 702;

[0083] One end of the mounting plate is fixedly mounted on the platform, and the other end is arranged vertically along the height direction of the frame 10.

[0084] The first sampling component 701 is fixedly installed on the left end of the mounting plate and can extend into the sample cup to take samples;

[0085] The second collection element 702 is fixedly installed on the right end of the mounting plate and can collect calcium chloride reagent from the reagent unit 60. The first collection element 701 and the second collection element 702 are arranged opposite each other.

[0086] Both the first data acquisition unit 701 and the second data acquisition unit 702 are electrically connected to the PLC.
