Description

Technical Field

[0001] The present invention relates to the technical field of medical scanning, in particular to three-dimensional scanning equipment for human body safety inspection. Background Art

[0002] The human body three-dimensional scanning equipment, also known as the 3D human body scanner, is a device that uses optical measurement technology, computer technology, image processing technology, digital signal processing technology, etc. to perform non-contact automatic measurement of the three-dimensional human body surface contour. This equipment can perform multi-angle and multi-directional instant scanning of the whole body or half of the human body in a short time (such as 3-5 seconds). The three-dimensional examination of the human body usually refers to the three-dimensional color ultrasound examination, which is a medical imaging technology that can be used to examine the conditions of different parts and organs. For women who are not pregnant, the three-dimensional color ultrasound examination can be used to check whether the uterus and appendages have lesions. At the same time, if the urinary system needs to be examined, the three-dimensional color ultrasound can check whether the kidneys, bladder and ureters have lesions. For breast examination, the three-dimensional color ultrasound is mainly used to observe whether the breast and the surrounding lymph nodes are abnormal. For pregnant women, the three-dimensional color ultrasound examination is mainly used to check whether the fetus, placenta and amniotic fluid are normal to exclude the possibility of a deformed fetus. It can more clearly observe the development of the fetus's heart, cleft lip, spina bifida, brain, kidney, bone and other organs. Generally speaking, pregnant women should undergo this examination around 20 weeks of pregnancy, and it is best not to exceed 28 weeks. In addition, three-dimensional color ultrasound can also be used to assess the size of the fetus before delivery.

[0003] For example, Chinese patent CN107156977A discloses a human body three-dimensional data scanning device, including a control and display host and a device body, the device body includes a longitudinal support component, a circular scanning component, a base component and a foot scanning component, the longitudinal support component connects the circular scanning component and the foot scanning component, the foot scanning component is arranged on the base component, the longitudinal support component drives the circular scanning component to slide up and down, the circular scanning component scans the surface of the human body, the base component supports the human body to stand or drives the human body to rotate, and the foot scanning component scans the data of the human body's feet. The present invention automatically controls the scanning of a person within a range of 306 degrees to obtain very accurate human body three-dimensional data, provides technical support for building a model of the person being measured, and can apply these data to various technical fields such as fitting and security inspection, promoting the development of human body three-dimensional data collection.

[0004] For example, Chinese patent CN108760010B discloses an armrest turntable mechanism of a three-dimensional human body scanning device, including a turntable and an armrest fixed on the turntable, the armrest including a handle, and the armrest also includes a fixed seat cover, an opening is provided on one side wall of the fixed seat cover, and a serration extending vertically is provided on the side edge of the opening; a slide rail is provided in the fixed seat cover, a push-pull electromagnet is provided on the sliding part of the slide rail, a bite piece engaged with the serration is fixed on the push-pull rod of the push-pull electromagnet, and the push-pull electromagnet is powered on and off to realize the engagement and separation of the bite piece and the serration; the handle is fixed on the top of the sliding part. The present invention can quickly adjust the height of the handle according to the height of the user by turning on and off the push-pull electromagnet, which saves time and effort and has strong adaptability, simple structure, low cost and long service life. The armrest will also make the user more stable during the rotation of the turntable without dizziness.

[0005] However, for the three-dimensional examination of pregnant women, the safety of pregnant women needs to be taken into consideration. For example, the three-dimensional scanning device in Comparative Document 1 can scan the human body within a 360-degree range and obtain accurate three-dimensional data, but the annular scanning component therein is of fixed size, which may squeeze the pregnant woman's belly during the scanning process, thereby causing harm to the pregnant woman's safety. If the annular scanning component is expanded and moved farther away, the scanned data may be inaccurate. For the scanning device in Comparative Document 2, although handrails are provided to make it more stable for people to stand, the platform below is rotating after all. People standing on the rotating platform may cause dizziness in pregnant women and cause harm. Therefore, a three-dimensional scanning device for human body safety inspection is proposed.

[0020] Compared with the prior art, the present invention provides a three-dimensional scanning device for human body security inspection, which has the following beneficial effects:

[0021] The three-dimensional scanning equipment for human body safety inspection prevents pregnant women from getting dizzy due to the 360-degree rotation of the human body during the human body inspection by fixing the stand and rotating the scanner, forcing the pregnant women to faint during the inspection and causing safety hazards.

[0022] The three-dimensional scanning device for human body safety inspection can achieve a comprehensive inspection of pregnant women by rotating two scanners around the pregnant woman and inspecting the feet at the bottom of the stand, thus avoiding scanning the normal human body and ignoring the scanning of the soles of the feet.

[0023] The three-dimensional scanning device for human body safety inspection can expand or contract the periphery of the two scanners through an adjustment device, and can control the distance between the scanner and the human body according to the body shape of the pregnant woman, thereby preventing the scanner from touching the human body during the rotating scanning process, thereby causing harm to the pregnant woman.

[0024] The three-dimensional scanning equipment for human body security inspection can accurately control the distance between the scanner and the human body by manually adjusting the gear through the adjustment device, thereby preventing the scanner from causing inaccurate data due to being too far away from the human body during the scanning process.

[0025] The three-dimensional scanning device for human body security inspection uses a spacing device at the bottom of the station plate to drive the connection frame to rotate around the spiral ring during the rotation of the scanner. The card slot provided on the spiral ring allows the scanning column to utilize the card connection of the rotating ring when rotating around the spiral ring, thereby driving the scanning column to rotate on its own. The scanning column can scan the feet multiple times through reciprocating rotation, which can increase the accuracy of the scanning data.

[0026] The three-dimensional scanning device for human body safety inspection sets a telescopic sleeve at the position of the scanner corresponding to the pregnant woman's belly, and uses an expansion device installed inside the telescopic sleeve. When the telescopic sleeve passes through the protective railings on the protective frame during the process of rotating around the pregnant woman, the protective railings can be squeezed outward to gradually move the resistance block outward, thereby driving the diamond frame composed of multiple groups of telescopic rods to deform, thereby realizing the outward expansion of the telescopic sleeve, preventing the scanner from touching the pregnant woman's belly when rotating around the pregnant woman. After scanning the belly, the movable plate in the movable groove is pulled by the spring, so that the scanner returns to its original state and continues to scan other parts of the pregnant woman closely.

Then, the scanners 4 on both sides of the stand plate 3 are driven by the rotating device to rotate around the pregnant woman's body, so as to facilitate a 360-degree scan of the pregnant woman. Before scanning, the two scanners 4 can be expanded or contracted outwards through the adjusting device according to the body shape of the pregnant woman, so that the two scanners can be The scanner 4 is moved closer according to the body shape of the pregnant woman to prevent the two scanners 4 from rubbing against the pregnant woman's body or being too far away from the pregnant woman, resulting in inaccurate scanning. During the scanning process of the pregnant woman, the lower end of the stand 3 also uses the spacing device to scan the pregnant woman's feet at intervals as the scanner 3 rotates. After the scanner 4 rotates, the part of the scanner 4 corresponding to the belly position can be opened through the expansion device according to the protection of the belly by the protection frame 5, so that the scanner 4 is prevented from touching the pregnant woman's belly when scanning the belly. After scanning the belly, the scanner 4 is restored to its original state to continue scanning other parts of the pregnant woman;

Before the three-dimensional detection scan, When the scanner 4 needs to be adjusted according to the body shape of the pregnant woman, the adjusting gear 13 on the connecting column at the lower end of the rotating disk 9 is rotated, so that the adjusting gear 13 drives the movable gear 14 to rotate. After the movable gear 14 rotates, two adjusting slots 16 on the movable gear 14 are connected with two adjusting columns 17. The two adjusting slots 16 are gradually moved toward one end by the rotation of the movable gear 14. During the movement, since the adjusting slots 16 are in a state of being inclined from the outer end to the inner end, the adjusting slots 16 pull the adjusting columns 17 to pull far and near, so that the telescopic rod 15 is driven by the adjusting columns 17 to move in the card slot 18, so that the telescopic rod 15 drives the two scanners 4 to move outward or inward, so as to adjust according to the body shape of the pregnant woman to avoid the scanner 4 from reaching the optimal position at a distance from the body during the rotation process.

[0046] The rotating device includes a motor 10, a second driving wheel 11 and a belt 12. The motor 10 is fixedly connected to the lower end of the fixed column 1, and the output end of the motor 10 passes through the fixed column 1 and extends to the inside. The output end of the motor 10 is fixedly connected to the second driving wheel 11 at one end inside the fixed column 1, and the belt 12 is movably connected between the second driving wheel 11 and the driving wheel 7 through the groove 8. When the motor 10 rotates, the output end of the motor 10 drives the second driving wheel 11 to rotate, and the second driving wheel 11 is wrapped with the driving wheel 7 by the belt 12, so that after the second driving wheel 11 rotates, the driving wheel 7 is driven to rotate by the belt 12, and the rotation of the driving wheel 7 causes the rotating sleeve 6 to rotate, thereby rotating the rotating disk 9 at the upper end.

[0047] The adjusting groove 16 is arranged in an arc shape, and the adjusting groove 16 is located on the movable gear 14 and is inclined from the outer end to the inner end.

The lower end of the station plate 3 is fixedly connected to the spiral ring 19 through two fixed columns 20, and the rotating sleeve 6 is fixedly connected to the connecting blocks 21 on both sides of the upper end of the rotating disk 9, and the outer ends of the two connecting blocks 21 are fixedly connected to the connecting frame 22, and a rotating ring 23 is arranged in the connecting frame 22, and one end of the rotating ring 23 is fixedly connected to the scanning column 24.

[0049] A limiting groove 25 is provided at the side end of the spiral ring 19, and two connecting frames 22 are movably sleeved on the spiral ring 19, and a rotating ring 23 is movably connected inside the two connecting frames 22, and a second card slot 26 is provided at one end of the rotating ring 23, and a scanning column 24 passes through the rotating ring 23 and extends into the second card slot 26, and the scanning column 24 and the limiting groove 25 are movably clamped together, and a through groove 27 is provided on the station disk 3 corresponding to the moving track of the spiral ring 19. When the rotating disk 9 drives the scanner 4 to rotate and scan, the rotating sleeve 6 at the lower end of the station disk 3 rotates, driving the connecting block 21 to make the connecting frame 22 rotate around the rotating sleeve 6, and the rotating ring 26 in the connecting frame 22 is movably rotated. 3. A spiral ring 19 is installed at the lower end of the station plate 3 through a fixed column 20. The rotation of the rotating sleeve 6 drives the connecting frame 22 and the rotating ring 23 to move in the spiral ring 19. A scanning column 24 is inserted in the rotating ring 23, and the scanning column 24 is engaged with the second card slot 26 in the spiral ring 19 through the rotating ring 23, so that the rotating ring 23 connected to the scanning column 24 can rotate when rotating around the spiral ring 19. When the scanning column 24 faces upward, it will correspond to the through slot 27 provided in the station plate 3, so as to scan the feet of the pregnant woman. After the scan, it will be turned over, so as to prevent problems in one scan, and multiple scans can be performed to achieve more accuracy.

[0050] The two scanners 4 include two scanning plates 28 and a telescopic sleeve 29. The telescopic sleeve 29 is fixedly connected between the two scanning plates 28, and the protective frame 5 is provided with a protective railing 30 corresponding to the position of the pregnant woman's belly. The protective railing 30 can be plastic and can be adjusted according to the size of the pregnant woman's belly, so as to expand the protective railing 30 to the periphery of the pregnant woman's belly.

[0051] The expansion device includes a rotating ring 31, a rotating rod 32, a second rotating shaft 33 and a second rotating rod 34. The two rotating rings 31 are movably connected together in an up-and-down manner, and the two rotating rings 31 are fixedly connected to the rotating rods 32, and the two rotating rods 32 are symmetrically arranged, and the other ends of the two rotating rods 32 are fixedly connected to the second rotating shaft 33, and the second rotating shaft 33 is movably connected to the second rotating rod 34, and the rotating rods 32 and the second rotating rods 34 on both sides are arranged in a rhombus shape, and multiple groups of rhombus-shaped expansion devices are movably connected together.

[0052] The lower end of the plurality of rhombus-shaped expansion devices corresponding to the position of the second node is movably connected with a movable plate 35, and a movable groove 36 is provided on the inner wall of the telescopic sleeve 29, and the movable groove 36 is movably connected with the movable plate 35, and the upper end of the plurality of rhombus-shaped expansion devices corresponding to the position of the second node is movably connected with a resistance block 37, and the resistance block 37 and the protective railing 30 are in a mutually parallel position. When the scanner 4 rotates around the pregnant woman, when the resistance block 37 in the telescopic sleeve 29 passes through the protective railing 30 in the protective frame 5, the resistance block 37 is affected by the arc shaped guardrail 30, it is squeezed outwardly so that the resisting block 37 drives the rotating ring 31 to retract outwardly, and the rotating ring 31 moves in a limited position in the movable groove 36 through the movable plate 35 at the lower end, so that the movement of the rotating ring 31 is vertical movement, and during the outward movement of the rotating ring 31, the rotating rod 32, the second rotating shaft 33 and the second rotating rod 34 are connected to each other and unfolded, thereby driving the telescopic sleeve 29 to expand outward, thereby preventing the telescopic sleeve 29 from touching the pregnant woman's belly during the rotation scanning process, thereby ensuring the safety of the pregnant woman during the scanning process.

[0053] Working principle: When a pregnant woman stands on the stand plate 3 and is ready to be scanned by the three-dimensional scanning device, the protective frame 5 is provided with two forward-protruding handles, so that the pregnant woman stands on the upper end of the stand plate 3 and the front end of the protective frame 5, and holds the two handles for support. Then, the scanners 4 on both sides of the stand plate 3 are driven by the rotating device to rotate around the body of the pregnant woman, so as to facilitate a 360-degree scan of the pregnant woman. Before scanning, the two scanners 4 can be expanded or contracted outwards through the adjusting device according to the body shape of the pregnant woman, so that the two scanners 4 can be close to each other according to the body shape of the pregnant woman to prevent the two scanners 4 from rubbing against each other. The scanner 4 is not mounted on the pregnant woman's body, or is too far away from the pregnant woman, resulting in inaccurate scanning. During the scanning of the pregnant woman, the lower end of the stand 3 also scans the pregnant woman's feet at intervals using the spacing device as the scanner 3 rotates. After the scanner 4 rotates, the part of the scanner 4 corresponding to the belly position can be opened through the expansion device according to the protection of the belly by the protection frame 5, so that the scanner 4 is prevented from touching the pregnant woman's belly when scanning the belly. After scanning the belly, the movable plate 35 is pulled in the movable groove 36 by the spring, so that the scanner 4 returns to its original state and continues to scan other parts of the pregnant woman.

[0054] When scanning is required, after the motor 10 rotates, the output end of the motor 10 drives the second driving wheel 11 to rotate, and the second driving wheel 11 is wrapped with the driving wheel 7 by the belt 12, so that after the second driving wheel 11 rotates, the driving wheel 7 is driven to rotate by the belt 12, and the rotation of the driving wheel 7 causes the rotating sleeve 6 to rotate, thereby causing the rotating disk 9 at the upper end to rotate;

[0055] Before the three-dimensional detection scan, when the scanner 4 needs to be adjusted according to the body shape of the pregnant woman, the adjusting gear 13 on the connecting column at the lower end of the rotating disk 9 is rotated, so that the adjusting gear 13 drives the movable gear 14 to rotate. After the movable gear 14 rotates, two adjusting columns 17 are connected to the two adjusting grooves 16 on the movable gear 14. The two adjusting grooves 16 are gradually moved to one end by the rotation of the movable gear 14. During the movement, since the adjusting groove 16 is in a state of being inclined from the outer end to the inner end, the adjusting groove 16 pulls the adjusting column 17 to pull far and near, so that the telescopic rod 15 is driven by the adjusting column 17 to move in the card slot 18, so that the telescopic rod 15 drives the two scanners 4 to move outward or inward, so as to adjust according to the body shape of the pregnant woman to avoid the scanner 4 reaching the optimal position at a distance from the body during the rotation process;

[0056] When the rotating disk 9 drives the scanner 4 to rotate and scan, the rotating sleeve 6 at the lower end of the station disk 3 rotates, driving the connecting block 21 to make the connecting frame 22 rotate around the rotating sleeve 6, and a rotating ring 23 is movably rotated in the connecting frame 22. A spiral ring 19 is installed at the lower end of the station disk 3 through the fixed column 20. The rotation of the rotating sleeve 6 drives the connecting frame 22 and the rotating ring 23 to move in the spiral ring 19. The scanning column 24 is inserted in the rotating ring 23, and the scanning column 24 is engaged with the second card groove 26 in the spiral ring 19 through the rotating ring 23, so that the rotating ring 23 connected to the scanning column 24 can rotate when rotating around the spiral ring 19, so that when the scanning column 24 faces upward, it will correspond to the through groove 27 opened on the station disk 3, so as to scan the feet of the pregnant woman, and it will be turned over after the scan, so as to prevent problems in one scan, and multiple scans can be performed to achieve more accuracy;

[0057] After the scanner 4 rotates and circles around the pregnant woman, when the resistance block 37 in the telescopic sleeve 29 passes through the protective railing 30 in the protective frame 5, the resistance block 37 is squeezed outward by the arc-shaped protective railing 30, so that the resistance block 37 drives the rotating ring 31 to extend and retract outward, and the rotating ring 31 moves in a limited position in the movable groove 36 through the movable plate 35 at the lower end, so that the movement of the rotating ring 31 is vertical movement, so that in the process of the rotating ring 31 moving outward, the rotating rod 32, the second rotating shaft 33 and the second rotating rod 34 are connected to each other and move to unfold, thereby driving the telescopic sleeve 29 to expand outward, thereby preventing the telescopic sleeve 29 from touching the pregnant woman's belly during the rotation scanning process, thereby ensuring the safety of the pregnant woman during the scanning process.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
