Description

Technical Field

[0001] This invention specifically relates to a human microcirculation detection device. Background Technology

[0002] Microcirculation refers to the blood circulation between arterioles and venules. Its basic function is the exchange of substances between blood and tissue fluid. Under normal circumstances, the blood flow in the microcirculation is adapted to the metabolic level of tissues and organs, ensuring adequate blood perfusion and regulating venous return. If microcirculation is impaired, it will directly affect the physiological functions of various organs. Therefore, detecting human microcirculation can accurately and directly determine a person's health.

[0003] Currently, the human microcirculation can be detected by observing the image features generated during blood reperfusion in the finger. This involves pressing the finger onto a glass slide to temporarily close the capillaries in the finger, then releasing them, and using a macro camera to perform machine vision analysis on the pressed area. The recovery time of the human microcirculation can be obtained by combining the data of the pressing time, which can be used as a reference material for clinical diagnosis.

[0004] However, currently, when patients press their fingers on the slide, the positions of the slide and the camera are fixed, and the pressing position of the finger is not precisely controlled by human. Existing human microcirculation detection devices based on visual features are not convenient to quickly calibrate the camera position relative to the fingertip pressing detection position, which leads to a decrease in the imaging effect of the fingertip during the detection process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a human microcirculation detection device to solve the technical problem mentioned in the background art: existing visual feature-based human microcirculation detection devices are inconvenient to quickly calibrate the camera position relative to the fingertip pressing detection position, resulting in a decrease in the camera effect on the fingertip during the detection process.

[0016] The rocker arm has one end connected to the output shaft of the servo motor, and a connecting groove is provided on one side of the pressure rod. The other end of the rocker arm is movably locked in the connecting groove.

[0017] In a preferred embodiment, the first housing has two sets of mounting slots, each containing a liftable support plate. The glass slide is mounted on the two sets of support plates and can be raised and lowered within the slots. An elastic element is provided between the support plate and the mounting slot.

[0018] In a preferred embodiment, a pressure block is provided at the bottom of one set of the support plates, and a reverse switch is provided in one set of the mounting slots, the reverse switch being electrically connected to the servo motor.

[0019] In a preferred embodiment, the bottom surface of the pressure rod is an arc surface, and a flexible pad is provided inside the arc surface.

[0020] In a preferred embodiment, the first adjustment component includes:

[0021] A first movable frame is slidably disposed within the second housing along a first direction, and the camera is disposed on the first movable frame;

[0022] A first synchronizing pulley, rotatably mounted on the second housing along its axis, and protruding beyond both the second and first housings; and

[0023] The second synchronous pulley is rotatably mounted on the second housing along its axis and is connected to the first synchronous pulley via a first synchronous belt. One side of the first synchronous belt is fixedly connected to the first movable frame.

[0024] In a preferred embodiment, a first anti-slip pad is provided between the first movable frame and the second housing.

[0025] In a preferred embodiment, the second adjustment component includes:

[0026] The second movable frame is slidably mounted on the first movable frame along the second direction, and the camera is fixedly mounted on the second movable frame;

[0027] The third synchronous pulley is rotatably mounted on the first movable frame along its axis. The second housing has a sliding groove, and the third synchronous pulley is movably mounted in the sliding groove and protrudes out of the first housing.

[0028] The fourth synchronous pulley is rotatably mounted on the first movable frame along its axis and is connected to the third synchronous pulley via a second synchronous belt. One side of the second synchronous belt is fixedly connected to the second movable frame.

[0030] In a preferred embodiment, the linkage component includes:

[0031] Mounting base, the first housing has a fixing groove, and the mounting base is fixedly installed in the fixing groove;

[0032] A movable plate is slidably mounted on the mounting base along a first direction, and the supplementary light is slidably mounted on the movable plate along its axis.

[0033] A snap-fit ​​ring is provided on the fill light; and

[0034] The snap-fit ​​bracket snaps into the snap-fit ​​ring and is connected to the second movable bracket.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. In use, the patient places their fingertip between a glass slide and a pressure rod. A control component rotates the pressure rod to press and fix the finger, causing temporary closure of capillaries due to deformation upon contact with the glass slide. The finger is then released, and a macro camera performs machine vision analysis on the pressed area. Combined with the compression time data, the recovery time of the body's microcirculation is obtained as a reference for clinical diagnosis. After fixing the finger, the camera's position in the first direction can be adjusted via a first adjustment component, and its position in the second direction via a second adjustment component. This allows the camera to quickly move directly below the pressed area for calibration. A supplementary light compensates for factors such as the patient's skin color and lighting conditions. The supplementary light's position moves with the camera's position under the action of a linkage component, effectively improving the imaging effect on the fingertip during the test.

[0037] 2. In use, the detection device uses a servo motor to drive a rocker arm to swing. During the swing, the rocker arm, in conjunction with the connecting groove, drives the pressure rod downward, causing the finger to press the glass slide. This downward movement of the glass slide also moves two sets of support plates. During the movement of the support plates, the elastic element is compressed until the pressure block contacts the reversing switch, which controls the servo motor to reverse. This ensures that the deformation of the elastic element remains constant each time the glass slide is pressed, thus guaranteeing that the pressure exerted by the glass slide on the finger is constant for patients with fingers of different sizes. This prevents the pressure rod from moving too much and causing injury to the patient's finger, while also avoiding insufficient movement of the pressure rod that would result in unclear test results, further improving the practicality of the detection device.

[0055] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0056] Example:

[0057] like Figure 1 , 2As shown in Figures 5, 6, and 7, the present invention provides a human microcirculation detection device, comprising a first housing 101 and a second housing 201. A supplementary light 403 is provided on one side of the first housing 101. The second housing 201 is disposed inside the first housing 101 and a camera 605 is disposed inside the second housing 201. A through groove 202 is provided on the second housing 201 for a glass slide 305 to pass through. A hinged pressure rod 303 and a control assembly for controlling the pressure rod 303 to rotate along its hinge point are provided on the second housing 201. The control assembly includes a mounting bracket 203 disposed on the second housing 201. A servo motor 301 is fixedly mounted on the mounting bracket 203. The output shaft of the servo motor 301 is connected to a rocker arm 302. A connecting groove 304 is provided on one side of the pressure rod 303, and the other end of the rocker arm 302 is movably engaged in the connecting groove 304.

[0058] In the initial state of use, the pressure lever 303 is open, allowing a finger to be placed between the lever 303 and the glass slide 305. Activating the servo motor 301 drives the rocker arm 302 to swing. During this swing, the rocker arm 302, in conjunction with the connecting groove 304, causes the pressure lever 303 to rotate along its hinge point with the second housing 201. As the lever 303 moves, it presses the finger onto the glass slide 305, fixing the fingertip's position and deforming the contact point between the finger and the slide 305, causing temporary closure of the finger's capillaries. Then, the servo motor 301 is reversed, opening the lever 303 and re-perfusing blood into the fingertip's capillaries. The changes in the fingertip are captured by the camera 605, and machine vision analysis of the pressed area is performed. Combined with the pressing time data, the recovery time of human microcirculation is obtained as a reference for clinical diagnosis. The supplementary lighting 403 compensates for objective factors such as the subject's skin color and lighting conditions, increasing the device's stability.

[0059] like Figure 2 , 3 As shown in Figure 4, in this embodiment, the first housing 101 has two sets of mounting slots 102. A liftable support plate 104 is installed in each mounting slot 102. A glass slide 305 is mounted on the two sets of support plates 104, allowing the glass slide 305 to move up and down within the through slot 202. An elastic element 107 is provided between the support plate 104 and the mounting slot 102. A pressure block 106 is provided at the bottom of one set of support plates 104, and a reverse switch 105 is provided in one set of mounting slots 102. The reverse switch 105 is electrically connected to the servo motor 301.

[0060] During the process of controlling the rotation of the pressure lever 303 to press the finger, when the finger comes into contact with the glass slide 305, it can drive the glass slide 305 to move downwards and squeeze the support plate 104. During the movement, the support plate 104 squeezes the elastic element 107 to prevent the finger from being subjected to excessive pressure. When the support plate 104 moves to a certain position, the pressure block 106 triggers the reversing switch 105 to reverse the servo motor 301, preventing the pressure lever 303 from moving too much and causing injury to the finger. At the same time, it prevents the servo motor 301 from moving too little, which would result in insufficient closure of the capillaries in the finger. This ensures that the pressure on fingers of different thicknesses is constant during the detection process, thus improving the applicability of the device.

[0061] like Figure 1 , 2 As shown, in this embodiment, the bottom surface of the pressure rod 303 is curved, and a flexible pad 306 is provided inside the curved surface. The flexible pad 306 protects the patient's finger side, preventing the patient from feeling uncomfortable during the test.

[0062] like Figure 5 , 6 As shown in Figure 8, in this embodiment, a first adjustment component is provided inside the second housing 201 to adjust the position of the camera 605 in a first direction within the second housing 201. The first direction is the X-axis. The first adjustment component includes a first movable frame 501 that is slidably disposed within the second housing 201 along the X-axis. The camera 605 is disposed on the first movable frame 501. A rotatable first synchronous wheel 502 and a second synchronous wheel 503 are provided on the second housing 201. The first synchronous wheel 502 protrudes outside the second housing 201 and the first housing 101. The second synchronous wheel 503 is connected to the first synchronous wheel 502 through a first synchronous belt 504. One side of the first synchronous belt 504 is fixedly connected to the first movable frame 501.

[0063] The first synchronous belt 504 can be moved by rotating a portion of the first synchronous pulley 502 protruding from the second housing 201. During this movement, the first synchronous belt 504 controls the sliding of the first movable frame 501 within the second housing 201 along the X-axis, thereby adjusting the position of the camera 605 on the X-axis. Furthermore, a first anti-slip pad 505 is provided between the first movable frame 501 and the second housing 201 to increase the friction between them, preventing the first movable frame 501 from sliding within the second housing 201 when not adjusted, thus avoiding any shift in the camera position.

[0064] like Figure 5 , 6As shown in Figure 9, in this embodiment, a second adjustment component is also provided inside the second housing 201 to adjust the position of the camera 605 in a second direction within the second housing 201. The second direction is the Y-axis, and the X-axis is perpendicular to the Y-axis on a plane. The second adjustment component includes a second movable frame 601 that is slidably mounted on the first movable frame 501 along the Y-axis. The camera 605 is fixedly mounted on the second movable frame 601. The first movable frame 501 is provided with a third synchronous wheel 602 and a fourth synchronous wheel 603 that are rotatable along its axis. A sliding groove 204 is provided on the second housing 201. The third synchronous wheel 602 is movably mounted in the sliding groove 204 and protrudes out of the first housing 101. The fourth synchronous wheel 603 is connected to the third synchronous wheel 602 through a second synchronous belt 604. One side of the second synchronous belt 604 is fixedly connected to the second movable frame 601.

[0065] The third synchronous wheel 602, protruding from the first housing 101, can be rotated by turning it. This, in conjunction with the fourth synchronous wheel 603, drives the second synchronous belt 604. During this movement, the second synchronous belt 604 causes the second movable frame 601 to slide along the Y-axis on the first movable frame 501, thereby adjusting the position of the camera 605 on the Y-axis. Combined with the first adjustment component, this allows for quick calibration of the camera 605 relative to the finger's pressing area, effectively improving the image quality and thus enhancing the detection performance. Furthermore, a second anti-slip pad 606 is provided between the second movable frame 601 and the first movable frame 501 to increase friction and prevent the second movable frame 601 from sliding on the first movable frame 501 when not adjusted, thus avoiding camera position shift.

[0066] like Figure 6 , 7 As shown in Figure 9, in this embodiment, the camera 605 and the fill light 403 are connected by a linkage component, which drives the fill light 403 to move synchronously with the camera 605. The linkage component includes a mounting base 401, a fixing groove 103 is provided on the first housing 101, the mounting base 401 is fixedly disposed in the fixing groove 103, a movable plate 402 is slidably disposed on the mounting base 401 along the X-axis, the fill light 403 is slidably disposed on the movable plate 402 along its axis, a snap-fit ​​ring 404 is provided on the fill light 403, and a snap-fit ​​bracket 607 is provided on the second movable frame 601, the snap-fit ​​bracket 607 snaps into the snap-fit ​​ring 404.

[0067] When the position of the camera 605 on the X-axis inside the second housing 201 is adjusted by the first adjustment component, the first movable frame 501 and the second movable frame 601 move simultaneously, and the fill light 403 moves through the snap-fit ​​bracket 607. During the movement, the fill light 403 drives the movable plate 402 to slide along the X-axis on the mounting base 401. When the position of the camera 605 on the Y-axis inside the second housing 201 is adjusted by the second adjustment component, only the second movable frame 601 moves. During the movement, the second movable frame 601 drives the fill light 403 to move along the axis of the fill light 403 on the movable plate 402 through the cooperation of the snap-fit ​​bracket 607 and the snap-fit ​​ring 404. This ensures that the fill light 403 can follow the position of the camera 605 when the position of the camera 605 is adjusted, so that it can provide fill light to the finger pressing position and improve the fill light effect.

[0068] Specific usage and beneficial effects of the present invention:

[0069] When using this detection device, the patient places their fingertip between a glass slide 305 and a pressure rod 303. A servo motor 301 drives a rocker arm 302 to swing, and the rocker arm 302, in conjunction with a connecting groove 304 on the pressure rod 303, rotates the pressure rod 303 to press down and fix the finger. This causes the capillaries between the finger and the glass slide 305 to temporarily close after contact deformation. The finger is then released, and a macro camera 605 performs machine vision analysis on the area where the finger was pressed. Combined with the pressing time data, the recovery time of the human microcirculation is obtained as a reference material for clinical diagnosis.

[0070] After the finger is fixed, the first synchronous belt 504 can be moved by rotating the first synchronous wheel 502, thereby causing the first movable frame 501 to slide along the X-axis within the second housing 201 to adjust the position of the camera 605 on the X-axis. The second synchronous belt 604 can be moved by rotating the third synchronous wheel 602, thereby causing the second movable frame 601 to slide along the Y-axis on the first movable frame 501 to adjust the position of the camera 605 on the Y-axis. This allows the camera 605 to quickly move directly below the finger pressing area to calibrate the camera position. The supplementary light 403 can compensate for objective factors such as the skin color and lighting conditions of the person being tested. The position of the supplementary light 403 can move with the position of the camera 605 under the action of the linkage component, thereby effectively improving the imaging effect of the fingertip during the detection process.

[0071] When in use, the detection device uses a servo motor 301 to drive a pressure rod 303 downward, causing the finger to press the glass slide 305. This downward movement of the glass slide 305 moves the two sets of support plates 104. During this movement, the support plates 104 compress the elastic element 107 until the pressure block 106 contacts the reversing switch 105. This controls the servo motor 301 to reverse, ensuring that the deformation of the elastic element 107 remains constant each time the glass slide 305 is pressed. This guarantees that the pressure exerted by the glass slide 305 on the finger remains constant for patients with fingers of different sizes, preventing damage to the patient's finger from excessive movement of the pressure rod 303, and avoiding unclear test results due to insufficient movement of the pressure rod 303. This further improves the practicality of the detection device.

[0072] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
