Description

Technical Field

[0001] This application relates to the fields of biomedicine and health technology, and in particular to a dual-mode detection device using traditional blue printing paper and a pressure sensor. Background Technology

[0002] Foot testing and biomechanical assessment are of great significance in clinical diagnosis and research. For example, in the clinical diagnosis of foot arch abnormalities and gait disorders, the traditional blue-printed footprint collection method has been used clinically for over 30 years due to its ease of operation and low cost. Doctors have developed stable usage habits and a high degree of trust in this method, especially in pediatric testing where blue-printed paper remains the mainstream testing method due to the lack of existing specialized equipment. Meanwhile, pressure plate testing systems, which can provide functional parameters such as pressure distribution and maximum pressure points, are gradually becoming important tools for biomechanical assessment and are widely used in the diagnosis and rehabilitation assessment of adult foot diseases.

[0003] Existing foot detection solutions include traditional paper footprint systems and professional pressure testing systems. Traditional paper footprint systems collect foot morphology footprints using carriers such as blue printing paper and tracing paper for basic structural assessment. Professional pressure testing systems, on the other hand, encompass resistive and capacitive pressure plates, enabling precise measurement of pressure parameters.

[0004] To meet the dual needs of some users, a few manufacturers have attempted to combine pressure plates with footprint collection functions, but most adopt an integrated design, which is structurally fixed and expensive, and cannot be compatible with the usage habits of traditional blue printing paper. For different weight groups, existing technologies design separate pressure plates for adults and children, which requires hospitals to purchase them repeatedly, significantly increasing procurement costs. In addition, although some 3D scanning devices can acquire the three-dimensional shape of the foot, they cannot provide pressure distribution data under weight-bearing conditions, which cannot meet the functional assessment needs of pediatric testing.

[0005] However, existing technologies still have several shortcomings. First, traditional paper footprint systems can only acquire morphological information, lacking functional pressure parameters, and the data is difficult to store long-term and accurately compare. Specialized pressure plates are expensive, incompatible with paper footprint systems, requiring users to invest repeatedly, and upgrade flexibility is poor. Second, existing pressure plates have fixed ranges, mostly suitable only for adults weighing 70kg±20kg, lacking sufficient accuracy for children or low-weight individuals. Purchasing separate pediatric pressure plates further increases costs, leading clinical institutions to generally abandon their purchases. Pediatric foot function testing has long relied on blue-printed paper or 3D scanning, leaving a technological gap. Finally, existing testing equipment cannot simultaneously acquire traditional blue-printed paper footprints and pressure data. Doctors find it difficult to compare familiar paper records with precise pressure parameters, reducing their trust in pressure test results. Furthermore, repeated testing can easily introduce errors, affecting diagnostic accuracy. Summary of the Invention

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail. Example

[0037] This embodiment discloses a dual-mode detection device for traditional blue printing paper and a pressure sensor. See [link to documentation]. Figure 1 and Figure 2 The system includes a housing 1, a base 2, a blueprinting mechanism 3, a foot pressure mechanism 4, and a control mechanism 5. The foot pressure mechanism 4 is mounted on the base 2 and is used to collect pressure data; it is suitable for both children and adults. The foot pressure mechanism 4 has a first pressure component 41 and a second pressure component, which are detachably connected to the control mechanism 5. The first pressure component 41 is suitable for adults, and the second pressure component is suitable for children. The blueprinting mechanism 3 is mounted on the housing 1 and located above the foot pressure mechanism 4. The blueprinting mechanism 3 is used to collect footprints and generate paper data. The control mechanism 5 is mounted on the base 2 and is electrically connected to the foot pressure mechanism 4. The control mechanism 5 is used to automatically match the corresponding range according to the module type, calibrate parameters, and output foot pressure distribution data.

[0038] Specifically, see Figure 1 and Figure 3The control mechanism 5 includes an MCU main control chip, signal conditioning circuit, analog-to-digital converter module, storage unit, communication interface module, power management unit, and human-machine interface circuit. The MCU main control chip is responsible for running the control algorithm, processing various instructions, and coordinating the operation of various components. The signal conditioning circuit amplifies and filters the weak analog signal output from the foot pressure mechanism 4, eliminating external electromagnetic interference and improving the signal-to-noise ratio. The analog-to-digital converter module converts the conditioned analog signal into a digital signal for the MCU main control chip to process; the conversion accuracy directly affects the accuracy of pressure detection. The storage unit stores module calibration parameters, device configuration information, and stored detection data and reports. The communication interface module includes USB, Bluetooth, and serial port communication interface circuits to enable data transmission between the control module and the display screen and external devices. The power management unit converts the external input power into a stable voltage required by the control module, and has overvoltage and overcurrent protection functions to ensure stable module operation. The human-machine interface circuit connects the touch display screen and buttons to transmit user operation commands and device feedback information.

[0039] In one embodiment, see Figure 1 and Figure 3 The first pressure component 41 includes an adult-sized pressure module with a measurement range of 50kg to 90kg. This adult-sized pressure module is fabricated using a three-layer structure, comprising a sensing layer, a substrate layer, and an interface layer. The sensing layer uses a 30×40 array of sensing units to ensure full coverage detection of foot pressure. The substrate layer is made of lightweight ABS engineering plastic, 3mm thick, balancing structural strength with weight reduction. The interface layer uses an integrated standardized electrical interface—a touch-sensitive pin—with pins defining power supply VCC, ground GND, signal output SIG, and calibration signal CAL.

[0040] In one embodiment, see Figure 1 and Figure 3 The second pressure component includes a children's version module with a measurement range of 10kg to 50kg. This children's version pressure module also employs a three-layer structure, comprising a sensing layer, a substrate layer, and an interface layer. The sensing layer uses a 20×30 array of sensing units to ensure full coverage detection of foot pressure. The substrate layer is made of lightweight ABS engineering plastic, 3mm thick, balancing structural strength with lightweight design. The interface layer uses an integrated standardized electrical interface—a touch-sensitive pin—with pins defining power supply VCC, ground GND, signal output SIG, and calibration signal CAL.

[0041] In one embodiment, see Figure 1 and Figure 3The first pressure assembly 41 and the second pressure assembly are marked with "Adult Version" and "Child Version" module installation positioning marks on their main bodies to avoid incorrect installation. In addition, the adult pressure module and the child pressure module each have two additional identification pins at their electrical interfaces. The resistance values ​​of these identification pins differ for different range modules; for example, the child version corresponds to a 1kΩ resistor, and the adult version corresponds to a 2kΩ resistor. The main circuit automatically identifies the module type by detecting the resistance value, eliminating the need for manual settings. Simultaneously, the data acquisition software has been upgraded to support automatic matching of the corresponding range calibration parameters based on the module type.

[0042] Specifically, see Figures 1 to 3 The housing 1 has a blue ink mounting part 11, and the blue ink mechanism 3 is mounted on the blue ink mounting part 11 and is detachably connected to the blue ink mounting part 11. The blue ink mechanism 3 has a material container 31, a color developing part 32, and an anti-slip part 33. The material container 31 is mounted on the body of the blue ink mechanism 3 and is used to hold ink containing blue dye. The anti-slip part 33 is stacked on the color developing part 32 and is used to increase the friction when the foot contacts the blue ink mechanism 3 and to prevent ink from penetrating to the foot. The color developing part 32 is placed on the material container 31 and is used to absorb ink containing blue dye and is dyed under pressure.

[0043] In one embodiment, a through test opening is provided in the middle of the housing 1 for the tester to place their foot on the foot pressure mechanism 4. The blue printing mounting part 11 includes a blue printing mounting groove formed on the housing 1, which is formed along the edge of the test opening.

[0044] In one embodiment, the blue printing mechanism 3 includes a blue printing frame that snaps into a blue printing mounting groove. A sealing sleeve is fixed on the contact surface between the blue printing frame and the housing 1, and an absorbent cotton cloth is also fitted on the sealing sleeve to prevent moisture and dust from entering the foot pressure unit and control mechanism 5 below from the blue printing frame.

[0045] In one embodiment, the container 31 includes a container rubber shell, which is mounted on the bottom of the blue printing frame to form an ink container cavity containing blue dye. The container rubber shell is fixedly connected to the blue printing frame. The container rubber shell is elastic and made of hydrogenated nitrile rubber, possessing good elasticity, good oil resistance, and resistance to swelling and cracking. During foot pressure application, it can sink down and contact the foot pressure mechanism 4, thereby acquiring pressure distribution data of the foot pressure while acquiring paperboard data.

[0046] In one embodiment, the color developing element 32 includes blue printing paper, which is laid on a blue printing frame containing blue dye ink. By placing a foot on the blue printing paper, the blue printing paper is pressed and absorbs the blue ink, and the footprint is reflected on the blue printing paper to obtain cardboard footprint data.

[0047] In one embodiment, the anti-slip component 33 includes anti-slip paper stacked on blue printing paper. The anti-slip paper has raised dots to increase the friction between the foot and the blue printing paper. It is also coated with a thin resin coating to prevent ink from penetrating and contaminating the foot. After the footprint is collected, the anti-slip paper is discarded and the blue printing paper is retained, ensuring the hygiene and safety of medical staff and patients.

[0048] Furthermore, the blue printing mechanism 3 has a fixing member 34, which is mounted on the body of the blue printing mechanism 3. Each end of the color developing member 32 and the anti-slip member 33 is pressed against by at least one set of fixing members 34. The fixing member 34 is magnetically connected to the blue printing mechanism 3.

[0049] Specifically, see Figure 1 and Figure 3 Each set of fixing components 34 includes a fixing iron strip and a fixing magnetic strip embedded in the blue printing frame. The number of fixing magnetic strips is the same as the number of fixing iron strips. The fixing iron strips and fixing magnetic strips are magnetically connected. During testing, the fixing iron strips are removed, the anti-slip paper from the blue printing box is placed on the blue printing frame, and then the fixing iron strips are placed back on. This fixes both ends of the blue printing paper and the anti-slip paper, preventing the blue printing paper from shifting during foot pressure, which could lead to blurred footprint edges and unclear footprints.

[0050] Specifically, see Figures 2 to 4 A quick-release frame 6 is fixedly mounted on the control mechanism 5. The quick-release frame 6 is used to guide and position the first pressure assembly 41 and the second pressure assembly. The control mechanism 5 has a conductive element 51, which is mounted on the bottom of the quick-release frame 6 and arranged along the depth direction of the quick-release frame 6. One end of the conductive element 51 extends through the quick-release frame 6 and into its interior. The conductive element 51 is elastic and conductive. After the first pressure assembly 41 or the second pressure assembly slides into the quick-release frame 6, it is pressed against the end of the conductive element 51 extending into the quick-release frame 6.

[0051] In one embodiment, the conductive element 51 includes multiple conductive springs spaced apart along the depth direction of the quick-release frame 6. One end of each conductive spring is electrically connected to the control mechanism 5 via a conductive base, and the other end extends into the quick-release frame 6 and presses against the electrical interface of the first pressure component 41 or the second pressure component. Thus, by changing the corresponding pressure component according to the test subject's weight, comprehensive testing of different weight groups can be achieved, especially filling the gap in pediatric foot functional testing, ensuring the accuracy of test data for each population, and eliminating the need to purchase additional dedicated pressure plates.

[0052] Specifically, see Figures 2 to 4The first pressure assembly 41 and the second pressure assembly are respectively connected to the quick-release frame 6 via a quick-release assembly 7, which has a quick-release function. The quick-release assembly 7 includes a sliding lock 71, a locking member 72, and a spring member 73: the sliding lock 71 is slidably mounted on the quick-release frame 6; one end of the locking member 72 is rotatably connected to the quick-release frame 6, and the other end is locked to the sliding lock 71 by a sliding lock, and can be unlocked by pushing; one end of the spring member 73 is rotatably connected to the quick-release frame 6, and the other end is rotatably connected to one end of the sliding lock 71, and has elasticity; one end of the sliding lock 71 is locked to the first pressure assembly 41 or the second pressure assembly. The first pressure assembly 41 and the second pressure assembly are each provided with at least one set of limiting parts 42, and the sliding lock 71 is provided with a hook part 710, one end of the hook part 710 is rotatably connected to the body of the sliding lock 71, and the other end is locked into the limiting part 42 to form a detachable connection. In addition, the sliding lock 71 is also provided with a locking part 711 and a guide part 712. The locking part 711 is used to lock one end of the locking member 72, and the guide part 712 is used to guide the locking member 72 to slide into or out of the locking part 711.

[0053] In one embodiment, see Figures 3 to 5 The sliding lock component 71 includes a sliding lock block, which is slidably installed within the quick-release frame 6. The quick-release frame 6 is provided with a guide portion 61, and the sliding lock component 71 is slidably connected to the guide portion 61. Specifically, the guide portion 61 is a double guide groove, on which the sliding lock block is installed and slidably connected. The hook portion 710 is also located within the double guide groove and is slidably connected to it. The double guide groove design not only guides the sliding lock block to slide stably but also provides a stable environment for the hook portion 710 to engage and disengage the pressure assembly, ensuring a stable and reliable engagement and disengagement process between the pressure assembly and the quick-release assembly 7.

[0054] In one embodiment, see Figures 3 to 5 The locking part 711 is a V-shaped groove formed on the sliding block, and the guide part 712 is a Y-shaped groove formed on the sliding block, and the V-shaped groove and the Y-shaped groove are connected.

[0055] In one embodiment, see Figures 3 to 5 The locking component 72 includes a locking rod, one end of which is hinged to the quick-release frame 6, and the other end extends into the Y-shaped slide groove and is slidably connected thereto.

[0056] In one embodiment, see Figures 3 to 5 The elastic element 73 includes a pop-out tension spring, one end of which is hinged to the quick-release frame 6 and the other end of which is hinged to the end of the sliding block.

[0057] In one embodiment, see Figures 3 to 5The hook part 710 includes an L-shaped hook. One end of the straight part of the L-shaped hook is hinged to the sliding block, and the other end of the hook is locked on the limiting part 42. The quick-release frame 6 has a through receiving groove for the L-shaped hook to be hidden when it is removed from the limiting part 42, so as to ensure that the pressure component can be smoothly removed from the quick-release frame 6.

[0058] In one embodiment, see Figures 3 to 5 The limiting part 42 includes a limiting groove and an ejecting protrusion. The limiting part 42 on the first pressure assembly 41 and the second pressure assembly are both provided on their sides.

[0059] The locking process for the pressure component is as follows: See Figures 3 to 5 When the first pressure component 41 slides into the quick-release frame 6, the ejector protrusion first contacts the sliding block, pushing the sliding block to slide along the double guide groove. The pop-out spring extends under the pull of the sliding block. The L-shaped hook gradually disengages from the receiving groove of the quick-release frame 6 along with the sliding block and gradually engages with the limiting groove. Until the locking rod slides along the Y-shaped groove into the V-shaped groove, the L-shaped hook is fully engaged in the limiting groove and is stably engaged in the V-shaped groove under the action of the pop-out spring. At this time, the first pressure component 41 is locked. When unlocking the first pressure component 41, a pushing force is applied to it. The locking rod disengages from the V-shaped groove and returns to its initial position along the Y-shaped groove under the reaction force of the pop-out spring. The sliding block also pushes the ejector protrusion out of the quick-release frame 6 under the reaction force of the pop-out spring. The L-shaped hook disengages from the limiting groove and enters the receiving groove of the quick-release frame 6. The first pressure component 41 pops out of the quick-release frame 6, and the unlocking is completed. It can be replaced with a pressure component of another range. Correspondingly, housing 1 is provided with a pop-out opening and an openable cover plate. The pop-out opening is formed on housing 1 for the passage of the pressure assembly. The cover plate is installed at the pop-out opening. The locking and unlocking process of the second pressure component is similar to that of the first pressure component 41. When the second pressure component slides into the quick-release frame 6, the ejector protrusion first contacts the sliding block, pushing the sliding block to slide along the double guide groove, and the spring extends. The L-shaped hook disengages from the receiving groove of the quick-release frame 6 along with the sliding block and gradually engages with the limiting groove. Until the locking rod slides into the V-shaped groove along the Y-shaped groove, the L-shaped hook is fully engaged in the limiting groove and is stably engaged in the V-shaped groove under the action of the spring. At this time, the second pressure component is locked. When unlocking the second pressure component, a pushing force is applied to it, the locking rod disengages from the V-shaped groove, and returns to its initial position along the Y-shaped groove under the reaction force of the spring. Under the reaction force of the spring, the sliding block pushes the ejector protrusion out of the quick-release frame 6, the L-shaped hook disengages from the limiting groove and enters the receiving groove of the quick-release frame 6, the second pressure component pops out of the quick-release frame 6, and the unlocking is completed. It can also be replaced with a pressure component of another range. This design allows for convenient and quick locking and unlocking of pressure components with different measurement ranges, improving the device's flexibility and efficiency. It also enables comprehensive testing for people of different weights, particularly filling the gap in pediatric foot function testing, ensuring the accuracy of data for all population groups, and eliminating the need to purchase additional dedicated pressure plates.

[0060] Specifically, see Figure 5 A protective part 52 is provided between the quick-release frame 6 and the control mechanism 5. The protective part 52 is installed between the quick-release frame 6 and the control mechanism 5 and is used to prevent moisture and dust from entering the control mechanism 5.

[0061] The protective part 52 includes a silicone sealing gasket, which wraps around the control mechanism 5 to prevent moisture and dust from entering the control mechanism 5 and also improves insulation performance.

[0062] The implementation principle of this embodiment is as follows: The dual-mode detection is achieved through the coordinated operation of the blue printing mechanism 3 and the foot pressure mechanism 4, combined with the intelligent regulation of the control mechanism 5.

[0063] During use, depending on whether the tester is an adult or a child, the appropriate first pressure component 41 or second pressure component is selected and locked into the quick-release frame 6 of the control mechanism 5 via the quick-release component 7. The control mechanism 5 automatically matches the corresponding range and retrieves calibration parameters by detecting the resistance value of the identification pins at the electrical interface of the pressure component. The tester's foot presses on the blue printing mechanism 3, and the anti-slip component 33 ensures stable contact of the foot. The blue ink in the container 31 is stained by the color developing component 32 under pressure, forming the footprint data on the paper plate of the foot. At the same time, the foot pressure is transmitted to the pressure component below. The sensing layer array of the pressure component collects the pressure distribution analog signal. After the signal is amplified and filtered by the signal conditioning circuit of the control mechanism 5, the signal is converted into a digital signal by the analog-to-digital converter module, and then processed by the MCU main control chip. Finally, the foot pressure distribution data is output. The detection data and report are stored in the storage unit and can also be transmitted to external devices through the communication interface module.

[0064] This embodiment achieves a dual-mode function of blue-printed footprint collection and pressure distribution detection. Its advantages are: First, it is equipped with dual-range pressure components for adults and children, enabling accurate detection of individuals of different weights through resistance identification and automatic calibration, filling a gap in pediatric foot functional testing; second, the pressure components adopt a quick-release structure, making disassembly and assembly convenient and accurate, eliminating the need for additional dedicated pressure plates and reducing operating costs; third, the blue-printing mechanism 3 features an anti-slip and anti-permeability design, ensuring hygienic safety during testing, while protective structures such as sealing sleeves and silicone gaskets effectively prevent moisture and dust intrusion, improving device stability; fourth, the control mechanism 5 integrates multiple interfaces and data storage functions, supporting multi-terminal data transmission and traceability. This solution solves problems such as the inability of traditional testing equipment to simultaneously meet the testing needs of adults and children, cumbersome disassembly and assembly of pressure components, separation of detection data and footprint records, and susceptibility to environmental interference. Example

[0065] The difference between this embodiment and Embodiment 1 is that, see [link to Embodiment 1] Figure 2 The housing 1 is equipped with a single pressure testing mechanism 8, which is connected to the housing 1 and is used to adapt to scenarios where it is not necessary to obtain blueprint paper footprint data.

[0066] Specifically, see Figure 2 and Figure 3 The single pressure testing mechanism 8 includes a coil spring 81, a roller shutter shaft 82, and a roller shutter fabric 83. The coil spring 81 consists of a coil spring housing, a coil spring, and a coil spring shaft: the coil spring housing is fixedly connected to the housing 1, and the coil spring is wound inside the coil spring housing; one end of the coil spring shaft passes through the coil spring housing, is fixedly connected to the center of the coil spring, and can rotate relative to the coil spring housing. At least two sets of coil spring 81 are provided; each end of the roller shutter shaft 82 is connected to a set of coil spring 81 and fixedly connected to the coil spring shaft; the roller shutter fabric 83 is wound onto the roller shutter shaft 82 and is made of modified polyurethane-coated elastic nylon, possessing both good flexibility and waterproof / oil-resistant properties.

[0067] Furthermore, one end of the roller blind 83 extends out of the housing 1, and an iron hook plate 84 is fixed to this end, which can be inserted into a hook groove 12 opened on the housing 1—the hook groove 12 is located on the side of the housing 1 away from the end of the roller blind 83 extending out; a hook plate magnet is embedded in the housing 1 near the hook groove 12, which can be magnetically connected with the iron hook plate 84. When the roller blind 83 is pulled out and laid along the surface of the blue printing mounting groove, the iron hook plate 84 is inserted into the hook groove 12, and the hook plate magnet further fixes the hook plate by attraction, ensuring that the roller blind 83 is stably laid on the blue printing mounting groove.

[0068] In addition, the part of the housing 1 with the blue printing mounting groove is made of iron. When the roller shutter cloth 83 is laid in the groove, the fixing magnetic strip on the blue printing frame is removed and pressed on the roller shutter cloth 83. The fixing magnetic strip is magnetically connected to the housing 1, thereby further pressing the edge of the roller shutter cloth 83 to prevent dust and moisture from entering the foot pressure unit.

[0069] The implementation principle of this embodiment is as follows: This embodiment adds a single pressure testing mechanism 8 to the first embodiment to adapt to detection scenarios that do not require blue-printed paper footprint data. In use, if it is not necessary to collect blue-printed paper footprints, the roller blind 83 can be pulled out from the roller blind shaft 82 and laid along the surface of the blue-printed paper mounting groove. Then, the iron hook plate 84 at the end of the roller blind 83 is inserted into the hook groove 12 on the other side of the housing 1. Initial fixation is achieved by the magnetic attraction between the hook plate magnet at the hook groove 12 and the iron hook plate 84. Next, the fixing magnetic strip on the blue-printed paper frame is removed and pressed against the edge of the roller blind 83. The magnetic attraction between the fixing magnetic strip and the iron housing 1 further tightens the roller blind 83, completing the setup of the single pressure testing mechanism 8. Following the operating procedure of Example 1, the appropriate pressure component for adults or children is selected and installed. The control mechanism 5 automatically identifies the module type and matches the corresponding range and calibration parameters. The tester's foot presses on the roller blind 83, and the pressure component collects the simulated signal of foot pressure distribution. After signal conditioning, analog-to-digital conversion, and calculation processing by the MCU main control chip of the control mechanism 5, the foot pressure distribution data is output. This achieves the function of flexible switching between dual-mode detection, retaining the dual-mode function of blue footprint and pressure detection in Example 1, and adding a single mode of pressure detection only, which can be flexibly selected according to actual detection needs.

[0070] The advantages of this embodiment are as follows: First, the roller blind 83 of the single pressure testing mechanism 8 is made of modified polyurethane coated elastic nylon, which has the characteristics of flexibility, water and oil resistance, and can protect the pressure components below from contamination and damage; Second, the roller blind 83 is fixed by a combination of magnetic attraction and snap-fit, which makes it stable to lay and easy to install and remove; Third, the edge of the roller blind 83 is pressed by the original fixing magnetic strip, which eliminates the need for additional fixing parts and reduces the cost of use.
