Description

Technical Field

[0001] This invention relates to the field of gastrointestinal tumor detection technology, specifically to a detection device for gastrointestinal tumor screening. Background Technology

[0002] With changes in people's lifestyles and the increasing aging of the population, the incidence of gastrointestinal tumors is showing an upward trend year by year, posing a serious threat to people's health. Early screening and diagnosis are crucial for improving the cure rate and survival rate of patients with gastrointestinal tumors. At present, there are various screening methods for gastrointestinal tumors. Among them, laboratory testing is an important screening method, which mainly includes the detection of tumor markers, fecal occult blood test, and fecal DNA test. Tumor marker detection uses equipment such as blood analyzers to detect specific markers in the blood. These markers will show abnormal expression during the occurrence and development of tumors, thus providing clues for the initial screening of gastrointestinal tumors. When examining blood in sample tubes, several factors can cause blood clots to form due to factors such as failure to immediately invert and mix the blood after collection, insufficient contact between the blood and anticoagulant, local activation of clotting factors, or failure to deliver the sample within one hour, leading to slow activation of clotting factors over time. If staff fail to detect this abnormality and proceed with the test, the blood clots can block the blood flow channels of the testing device, including critical components such as the injection needle, tubing, and counting chamber of the blood analyzer. Once these channels are blocked, blood cannot flow normally, preventing subsequent samples from entering the testing system and causing further complications. Interruptions in testing require time to clear blockages and may even necessitate the replacement of damaged components, increasing equipment maintenance costs and repair time. Furthermore, clots alter the physical properties of blood, affecting the accurate counting and analysis of various blood components by the testing equipment. This can lead to inaccurate counts of cells such as white blood cells, red blood cells, and platelets, failing to accurately reflect the patient's actual blood condition and thus impacting the doctor's diagnosis and judgment. Additionally, because clots interfere with the testing process, false positive or false negative results may occur. False positive results can lead doctors to mistakenly believe that the patient has a certain disease, resulting in unnecessary further examinations and treatments.

[0003] Therefore, this invention proposes a detection device for screening gastrointestinal tumors to solve the above problems. Summary of the Invention

[0007] As a further embodiment of the present invention: a fixing ring is fixedly connected to the upper end face of the internal gear ring, and an arc-shaped plate is fixedly connected to the inner ring surface of the fixing ring at equal intervals. A limiting plate is attached to the arc-shaped plate, and the limiting plate is fixedly connected to the outer surface of the drive shaft.

[0008] As a further aspect of the present invention: the auxiliary detection mechanism includes a lifting plate, each of which is vertically slidably connected to the inside of the sample placement frame, and each of the lower ends of the lifting plate is fixedly connected to a linkage column, which is slidably connected through the turntable and the sample placement frame.

[0009] As a further embodiment of the present invention: a lifting plate is attached to the lower end of the linkage column, the lifting plate is horizontally slidably connected to the inside of the turntable, a sliding column is fixedly connected to the side wall of the lifting plate, the sliding column is slidably connected to the turntable, and a push plate is fixedly connected to one end of the sliding column through the turntable.

[0010] As a further aspect of the present invention: a spring is fixedly connected to the side of the push plate near the turntable, the end of the spring away from the push plate is fixedly connected to the outer surface of the turntable, and the spring is sleeved on the outer surface of the sliding column.

[0011] As a further aspect of the present invention: the auxiliary detection mechanism further includes a support plate, which is fixedly connected to the side wall of the support frame. A second drive motor is fixedly connected to the upper surface of the support plate, and a cam is fixedly connected to the output end of the second drive motor.

[0013] As a further aspect of the present invention: a threaded rod is fixedly connected to the upper end face of the pressing plate, and the threaded rod is threadedly connected to the lower end of the lifting column.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a detection device for screening gastrointestinal tumors, which has the following beneficial effects: The designed sample clot detection mechanism detects clots within the blood before it is delivered to the blood analyzer for testing. An alarm is triggered promptly if any abnormality is detected, preventing clots from entering critical components such as the injection needle, tubing, and counting chamber, thus reducing time spent clearing blockages, lowering the probability of component damage due to clots, extending equipment lifespan, and reducing maintenance costs and frequency. Furthermore, eliminating clot interference before testing ensures accurate counting and analysis of various blood components, providing a more accurate reflection of the patient's blood condition and offering reliable diagnostic information for doctors. It also prevents false positives or false negatives caused by clots, reducing the possibility of misdiagnosis and missed diagnosis. For example, it avoids unnecessary further testing due to false positives and delays in patient care due to false negatives, thus protecting patient health and safety.

[0015] By using a set of levers, internal toothed rings, fixing rings, arc-shaped plates, and limiting discs, blood samples can be intermittently rotated sequentially to the detection points of the infrared sensor and the blood analyzer itself. This not only ensures that each blood sample is precisely rotated to the designated detection point, guaranteeing that the infrared sensor can accurately identify the sample's position and status, but also allows the blood analyzer to accurately detect the sample, avoiding inaccurate test data caused by sample position deviations and providing doctors with reliable diagnostic evidence. Furthermore, the intermittent rotation method allows each sample to be tested in a relatively independent and stable environment, reducing potential interference between adjacent samples and further improving the accuracy and reliability of the test results.

[0016] The auxiliary detection mechanism allows for a slight up-and-down shaking of the blood sample as it moves to the infrared sensor. This facilitates the detection of clots within the blood sample. When the blood sample is stationary, clots may be hidden inside and difficult for the infrared sensor to detect. The slight up-and-down shaking causes the blood to flow, changing the position of the previously hidden clots and exposing them more fully to the infrared sensor's detection range. This increases the probability of clot detection and reduces missed detections. Furthermore, because the shaking quickly exposes the clots, the infrared sensor does not need to repeatedly scan and judge the same location for a long time. It can complete the detection of clots inside the blood sample in a shorter time, accelerating the detection speed of a single sample and thus improving overall detection efficiency to meet the needs of large-scale blood testing.

[0017] The height of the pressing plate can be adjusted by using a threaded rod, ensuring that the pressing plate always remains in contact with the upper end of the sample tube. This facilitates a slight up-and-down reciprocating motion of the sample tube. Since sample tubes of different sizes have varying heights, adjusting the pressing plate height via the threaded rod not only allows the device to adapt to various sample tube sizes, expanding its overall applicability and improving its versatility and flexibility, but also eliminates the need for specialized equipment or complex adjustments based on different sample tube sizes. Furthermore, the fact that the pressing plate remains in contact with the upper end of the sample tube provides a stable force when driving the sample tube to shake, preventing abnormal shaking caused by uneven or unstable forces and protecting the sample tube's safety.

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0022] This embodiment provides a detection device for screening gastrointestinal tumors, such as... Figure 1 - Figure 8 As shown, the blood analyzer includes a blood analyzer body 1 and a base plate 2. The base plate 2 is fixedly connected to the front of the blood analyzer body 1. A detection point 7 is fixedly connected to the side of the blood analyzer body 1 near the base plate 2. A rotating shaft 8 is rotatably connected to the upper end of the base plate 2. A turntable 3 is fixedly connected to the upper end of the rotating shaft 8. A sample placement frame 4 is fixedly connected to the outer surface of the turntable 3 at equal intervals in a ring. The blood analyzer also includes a sample clot detection mechanism and an auxiliary detection mechanism. The sample clot detection mechanism includes a support frame 501. An infrared sensor 502 is fixedly connected to the support frame 501. An alarm 503 is electrically connected to the infrared sensor. The alarm 503 is fixedly connected to the upper end of the support frame 501. A through groove 512 is opened on the outer surface of the sample placement frame 4 near the infrared sensor 502. The sample clot detection mechanism is used to trigger an alarm when blood clots occur inside the sample cylinder.

[0023] In this embodiment, as Figure 1 and Figure 2As shown, a mounting bracket 504 is fixedly connected to the upper end of the base plate 2. A first drive motor 505 is fixedly connected to the upper end of the mounting bracket 504. A drive shaft 506 is fixedly connected to the output end of the first drive motor 505. A dial plate 507 is fixedly connected to the lower end of the drive shaft 506. An internal gear ring 508 is sleeved on the outer surface of the dial plate 507. The internal gear ring 508 is fixedly connected to the upper end of the turntable 3. When the first drive motor 505 is turned on to drive the drive shaft 506 to rotate, the dial plate 507 connected to the lower end of the drive shaft 506 can rotate and push the internal gear ring 508 to rotate intermittently, thereby driving the turntable 3 connected to the lower end of the internal gear ring 508 to rotate synchronously.

[0024] In this embodiment, as Figure 2 As shown, a fixing ring 510 is fixedly connected to the upper end face of the internal gear ring 508. An arc-shaped plate 511 is fixedly connected to the inner ring surface of the fixing ring 510 at equal intervals. A limiting plate 509 is attached to the arc-shaped plate 511. The limiting plate 509 is fixedly connected to the outer surface of the drive shaft 506. Through the mutual contact of the arc-shaped plate 511 and the limiting plate 509, the position of the internal gear ring 508 can be limited and fixed simultaneously after the dial plate 507 rotates the internal gear ring 508.

[0025] In existing technologies, when examining blood in sample tubes, several factors can cause blood clots to form. If staff fail to detect this abnormality and proceed with testing, the blood clots can block the blood flow channels of the testing device, such as the injection needle, tubing, and counting chamber of the blood analyzer. Blockage prevents normal blood flow, hindering subsequent sample entry into the testing system and causing testing interruptions. This necessitates time to clear the blockage and may even require replacing damaged components, increasing equipment maintenance costs and repair time. Furthermore, clots alter the physical properties of the blood, affecting the accurate counting and analysis of various blood components. This can lead to inaccurate counts of white blood cells, red blood cells, platelets, and other cells, failing to accurately reflect the patient's actual blood condition and impacting the doctor's diagnosis. Additionally, because clots interfere with the testing process, false positives or false negatives can occur. False positives can mislead doctors into believing the patient has a disease, leading to unnecessary further testing. Compared to existing technologies, this method eliminates unnecessary further examinations and treatments by detecting blood clots before they are introduced into the blood analyzer body 1 for testing. It provides timely alarms in case of abnormalities, preventing clots from entering critical components such as the injection needle, tubing, and counting chamber, thus reducing time spent clearing blockages, lowering the probability of component damage due to clots, extending equipment lifespan, and reducing maintenance costs and frequency. Furthermore, eliminating clot interference before testing ensures accurate counting and analysis of various blood components, providing doctors with reliable diagnostic information and preventing false positives or false negatives caused by clots. This reduces the possibility of misdiagnosis and missed diagnosis, such as avoiding unnecessary further examinations due to false positives or delays in treatment due to false negatives, thus protecting patient health and safety.

[0026] At other levels, this embodiment also provides an auxiliary detection mechanism for shaking the blood inside the sample tube to facilitate the detection of clots, such as... Figure 1 - Figure 8 As shown, the auxiliary testing mechanism includes a lifting plate 611, which is vertically slidably connected to the inside of the sample placement frame 4. The lower end of the lifting plate 611 is fixedly connected to a linkage column 612, which is slidably connected to the turntable 3 and the sample placement frame 4.

[0027] In this embodiment, as Figure 8As shown, a lifting plate 613 is attached to the lower end of the linkage column 612. The lifting plate 613 is horizontally slidably connected to the inside of the turntable 3. A sliding column 605 is fixedly connected to the side wall of the lifting plate 613. The sliding column 605 is slidably connected to the turntable 3. A push plate 601 is fixedly connected to one end of the sliding column 605 through the turntable 3. When the sliding column 605 slides into the inside of the turntable 3, it will drive the lifting plate 613 to move synchronously. By the different heights of the upper surface of the lifting plate 613, the linkage column 612 can be pushed to rise.

[0028] In this embodiment, as Figure 3 As shown, a spring 606 is fixedly connected to the side of the push plate 601 near the turntable 3. The end of the spring 606 away from the push plate 601 is fixedly connected to the outer surface of the turntable 3. The spring 606 is sleeved on the outer surface of the slide column 605. When the push plate 601 is subjected to force and approaches the turntable 3, it will push the slide column 605 into the turntable 3 and squeeze the spring 606 at the same time. When the force on the push plate 601 disappears, the rebound force of the spring 606 can push the push plate 601 away from the turntable 3 automatically and pull the slide column 605 out of the turntable 3.

[0029] In this embodiment, as Figure 3 As shown, the auxiliary detection mechanism also includes a support plate 602, which is fixedly connected to the side wall of the support frame 501. A second drive motor 603 is fixedly connected to the upper end of the support plate 602, and a cam 604 is fixedly connected to the output end of the second drive motor 603. The cam 604 and the push plate 601 are on the same horizontal line, and the outer surface of the cam 604 is in contact with the side wall of the push plate 601. When the second drive motor 603 is turned on to drive the cam 604 to rotate, the cam 604 can push the push plate 601 to move horizontally closer to the turntable 3.

[0030] In this embodiment, as Figure 5 As shown, the auxiliary testing mechanism also includes a lifting column 607, which is slidably connected to the support frame 501. A disc 608 is fixedly connected to the upper end of the lifting column 607, and a pressing plate 609 is provided below the lifting column 607. The pressing plate 609 is located directly above the sample placement frame 4. The pressing plate 609 can limit the upper end of the sample tube.

[0031] In this embodiment, as Figure 5 As shown, a threaded rod 610 is fixedly connected to the upper end face of the pressing plate 609. The threaded rod 610 is threadedly connected to the lower end of the lifting column 607. Through the threaded connection between the threaded rod 610 and the lifting column 607, the threaded rod 610 can be rotated and slid into or out of the lifting column 607, thereby adjusting the height of the pressing plate 609.

[0032] Compared with existing technologies, this method can gently shake the blood sample up and down when the sample placement frame 4 moves the blood sample to the infrared sensor 502. This allows the infrared sensor 502 to detect clots inside the blood sample. When the blood sample is stationary, clots may be hidden inside the blood and not easily detected by the infrared sensor 502. However, the gentle up-and-down shaking causes the blood to flow, which not only changes the position of the previously hidden clots but also fully exposes them within the detection range of the infrared sensor 502, increasing the probability of clot detection and reducing missed detections. Moreover, because the shaking can quickly expose the clots, the infrared sensor 502 does not need to repeatedly scan and judge the same position for a long time. It can complete the detection of clots inside the blood sample in a shorter time, speeding up the detection speed of a single sample and thus improving the overall detection efficiency, meeting the needs of large-scale blood testing.

[0033] The overall working process and principles involved in the above embodiments are as follows: It should be noted that the infrared sensor 502 determines whether there are clumps inside the liquid by monitoring the state of liquid flow. When medical personnel need to perform blood tests, they first rotate the pressure plate 609 according to the height of the sample tube. Since a threaded rod 610 is connected to the upper surface of the pressure plate 609, and the threaded rod 610 is threadedly connected to the lower end of the lifting column 607, the rotation of the pressure plate 609 drives the threaded rod 610 to rotate synchronously. This allows the threaded rod 610 to slide into or out of the lifting column 607, thereby adjusting the height of the pressure plate 609 so that it always fits against the upper end of the sample tube, facilitating the movement of the sample. The tube wobbles slightly up and down. Different sizes of sample tubes have different heights. By adjusting the height of the pressing plate 609 with the threaded rod 610, the device can be adapted to various sizes of sample tubes, expanding its overall applicability and improving its versatility and flexibility. There is no need to replace the equipment with special equipment or make complicated adjustments due to different sample tube sizes. Moreover, the pressing plate 609 always fits against the upper end of the sample tube, providing a stable force when driving the sample tube to shake. This avoids abnormal shaking of the sample tube due to uneven or unstable force, thus protecting the safety of the sample tube. After adjusting the height of the pressing plate 609, place the sample tube containing blood into the sample placement frame 4, then turn on the first drive motor 505 to drive the drive shaft 506 to rotate. Since a lever 507 is fixedly connected to the lower end of the drive shaft 506, and an internal toothed ring 508 is fitted on the outer surface of the lever 507, and the internal toothed ring 508 is fixedly connected to the upper surface of the turntable 3, and the turntable 3 is rotatably connected to the upper surface of the base plate 2 via the rotating shaft 8, the drive shaft 506 rotates... The drive shaft 506 can drive the dial plate 507 to rotate synchronously. When the dial plate 507 and the internal gear ring 508 are in contact, as the dial plate 507 continues to rotate, the dial plate 507 will push the internal gear ring 508 to drive the turntable 3 to rotate intermittently on the upper surface of the base plate 2. When the rotating shaft 8 drives the dial plate 507 away from the internal gear ring 508, since the outer surface of the drive shaft 506 is connected to the limiting plate 509, the limiting plate 509 and the arc plate 511 connected to the inner ring surface of the fixing ring 510 are compatible. Therefore, as the lever 507 and the internal gear ring 508 separate, the drive shaft 506 will drive the limiting disk 509 to rotate into the arc plate 511, limiting the arc plate 511. Through the arc plate 511, the fixing ring 510 and the internal gear ring 508, the position of the turntable 3 is fixed, so that the turntable 3 drives the sample tube inside the sample placement frame 4 on the upper end face to rotate intermittently to the infrared sensor 502 and the detection point 7 of the blood analyzer body 1. This not only allows each blood sample to rotate precisely to the designated detection point 7, ensuring that the infrared sensor 502 can accurately identify the sample position and status, but also allows the blood analyzer body 1 to accurately detect the sample, avoiding inaccurate detection data caused by sample position deviation, providing doctors with reliable diagnostic basis. Moreover, the intermittent rotation method allows each sample to be detected in a relatively independent and stable environment, reducing possible interference between adjacent samples, and further improving the accuracy and reliability of the detection results. When the sample tube inside the sample placement frame 4 rotates to the infrared sensor 502, the infrared sensor 502 illuminates the sample tube inside the sample placement frame 4 through the through-slot 512, performing infrared detection on the blood inside the sample tube to determine if there are clots. If the blood is normal, it continues to rotate and be transported to the detection point 7 on the front of the blood analyzer body 1 for analysis. If the blood contains clots, the infrared sensor 502 will electrically connect to the alarm 503, activating the alarm 503. This not only prevents clots from entering the critical parts of the blood analyzer body 1, such as the injection needle, tubing, and counting cell, but also effectively prevents... By removing these blockages, the time spent clearing blockages is reduced, the probability of equipment damage due to physical damage caused by clots is lowered, the service life of the equipment is extended, and the maintenance cost and repair frequency are reduced. Moreover, eliminating clot interference before testing ensures that the testing equipment can accurately count and analyze various components in the blood, making the test results more realistically reflect the actual condition of the patient's blood, providing doctors with reliable diagnostic evidence, and preventing false positive or false negative results caused by clots. This reduces the possibility of misdiagnosis and missed diagnosis, such as avoiding doctors arranging unnecessary further examinations for patients due to false positive results and delaying patients' treatment due to false negative results, thus protecting the health and safety of patients. When the turntable 3 rotates and moves the sample placement frame 4 to the infrared sensor 502, the upper end of the sample tube inside the sample placement frame 4 will move directly below the pressing plate 609 and come into contact with it. At this time, the second drive motor 603 is simultaneously turned on, driving the cam 604 connected to the output end to rotate. Since the cam 604 and the push plate 601 are in contact, as the cam 604 rotates, when the protruding part of the cam 604 comes into contact with the push plate 601, it will push the push plate 601 closer to the turntable 3, causing the sliding column 605 connected to the push plate 601 to slide into the turntable 3. At the same time, it will push the push plate 601 closer to the outer surface of the turntable 3. The connected spring 606 is compressed. Since the end of the sliding column 605 away from the push plate 601 is connected to the lifting plate 613, and the upper end of the lifting plate 613 is attached to the linkage column 612, the linkage column 612 is slidably connected to the turntable 3 and the sample placement frame 4, and the linkage column 612 is fixedly connected to the lower end face of the lifting plate 611, as the sliding column 605 slides, the sliding column 605 will push the lifting plate 613 to move synchronously, so that the lifting plate 613 pushes the linkage column 612 upward, causing the lifting plate 611 to slide synchronously upward inside the sample placement frame 4. At this time, the lifting plate 611 will push the sample tube placed inside the sample placement frame 4. As the sample tube rises, the pressing plate 609, which is attached to the upper surface of the sample tube, rises simultaneously. The threaded rod 610 pushes the lifting column 607 to slide upwards on the support frame 501, allowing the pressing plate 609 and the lifting plate 611 to clamp the sample tube. When the protruding part of the cam 604 rotates and separates from the push plate 601, the rebound force of the spring 606 pushes the push plate 601 away from the turntable 3, causing the sliding column 605 to slide out of the turntable 3, pulling the lifting plate 613 to slide in the opposite direction inside the turntable 3. At this time, due to the influence of the disc 608 connected to the upper end of the lifting column 607 and the weight of the sample tube itself, it will automatically descend. Therefore, through the cooperation of cam 604 and spring 606, the sample tube can be driven to gently oscillate up and down. Different specifications of sample tubes have different heights. By adjusting the height of the pressing plate 609 through the threaded rod 610, the device can be adapted to various specifications of sample tubes, expanding the overall applicability and improving the overall versatility and flexibility. There is no need to replace the equipment with special equipment or make complicated adjustments due to different sample tube specifications. Moreover, the pressing plate 609 always fits against the upper end of the sample tube, providing a stable force when driving the sample tube to oscillate, avoiding abnormal oscillation of the sample tube due to uneven or unstable force, and protecting the safety of the sample tube.
