Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device auxiliary sensing technology, specifically a detachable and reusable surface pressure sensor for pectus carinatum correction devices. Background Technology
[0002] A pectus carinatum (pigeon chest) corrector is a non-surgical device specifically designed to correct sternal anterior protrusion deformity. It helps improve chest contour through gentle, continuous physical pressure, and is particularly suitable for corrective intervention during adolescent development. Its design typically uses medical-grade materials to conform to the chest curve. Through adjustable pressure bands or support systems, it gradually guides the sternum and costal cartilage back to their normal positions. Compared to traditional surgery, the corrector is non-invasive, portable, and flexible in use. Users need to wear it regularly under the guidance of a doctor, and combine it with breathing exercises and physical training to enhance the balance of the chest and back muscles and improve the corrective effect. Early intervention is especially important. For patients with mild to moderate pectus carinatum, continuous use can effectively improve appearance and alleviate the psychological stress caused by the deformity.
[0003] Pigeon chest correctors achieve their corrective effect by applying continuous and stable pressure to the chest cavity. The pressure level directly affects the safety and effectiveness of the correction—too little pressure results in ineffective correction, while too much pressure can lead to skin damage and impaired blood circulation. Currently, most pectus carinatum correctors use fixed, integrated pressure sensors, which present two major problems:
[0004] Firstly, the entire corrector needs to be replaced after the sensor is damaged, which results in high operating costs.
[0005] Secondly, it cannot be adapted to different models of orthotics or adjust the sensor position according to the user's body shape, resulting in poor versatility and low reusability. Utility Model Content
[0006] To address the aforementioned issues, this application provides a detachable and reusable surface pressure sensor for pectus carinatum correction devices, solving the problems of inflexible sensor disassembly and limited compatibility.
[0007] A detachable and reusable surface pressure sensor for a pectus carinatum corrector includes a sensor body, a pectus carinatum corrector for a patient to wear is disposed around the sensor body, and a flexible pressure sensing sheet for collecting pressure data is connected to the outside of the sensor body.
[0008] The sensor body has a detachable connection component that is easy to install and replace. The detachable connection component includes a magnetic patch, which is fixedly installed on the outside of the sensor body. The pectus carinatum is attached to the outside of the magnetic base that engages with the magnetic patch.
[0009] The detachable connection assembly also includes multiple hook and loop fasteners, which are fixedly installed on the outside of the sensor body. The outside of the pectus excavatum corrector is covered with hook and loop fasteners that match the hook and loop fasteners.
[0010] Preferably, a substrate is fixedly mounted on the inner side of the sensor body, and a signal processing unit is fixedly mounted on the outer side of the substrate. The signal processing unit and the flexible pressure sensing sheet are electrically connected.
[0011] Preferably, a display screen is fixedly mounted on the outside of the sensor body, and multiple control buttons are mounted on the top of the sensor body.

It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0027] like Figure 1 As shown, this utility model embodiment provides a detachable and reusable surface pressure sensor for a pectus carinatum corrector, including a sensor body 1, a pectus carinatum corrector 10 for the patient to wear, and a flexible pressure sensing sheet 3 for collecting pressure data connected to the outside of the sensor body 1. The flexible pressure sensing sheet 3 is a thin film pressure sensor made of polyimide substrate.
[0028] Furthermore, such as Figure 1 , Figure 2 As shown, a detachable connection assembly is installed on the outside of the sensor body 1 for easy installation and replacement. The detachable connection assembly includes a magnetic patch 7, which is made of neodymium iron boron magnet. The magnetic patch 7 is fixedly installed on the outside of the sensor body 1. A magnetic base 6 is attached to the outside of the pectus excavatum corrector 10 to engage with the magnetic patch 7.
[0029] Furthermore, such as Figure 1 , Figure 2 As shown, the detachable connection assembly also includes multiple hook and loop fasteners 9, which are fixedly installed on the outside of the sensor body 1. The outside of the pectus excavatum corrector 10 is covered with hook and loop fasteners 8 that cooperate with the hook and loop fasteners 9.
[0030] In this embodiment, the operator first fixes the magnetic base 6 and the hook and loop fastener 8 to the outside of the pectus carinatum 10, close to the position where pressure monitoring is required, using adhesive or other methods. Then, the operator aligns the magnetic patch 7 with the magnetic base 6 to fix the sensor body 1. Finally, the operator gently presses the sensor body 1 to connect the hook and loop fastener 8 and the hook and loop fastener 9, thus fixing the sensor body 1. Through the dual connection structure of magnetic and hook and loop fasteners, the sensor and the orthodont can be disassembled and assembled without damage. A single sensor can be adapted to multiple orthodonts. If damaged, only the sensor body 1 needs to be replaced, reducing the cost of use. Moreover, the combination of magnetic patch and hook and loop fasteners allows for flexible adjustment of the sensor position to adapt to different models of orthodonts and different users' chest shapes, ensuring accurate pressure sampling points.
[0031] Furthermore, such as Figure 3 As shown, a base plate 11 is fixedly installed on the inner side of the sensor body 1 for mounting the electrical unit. A signal processing unit 12 is fixedly installed on the outer side of the base plate 11. The signal processing unit 12 integrates an MCU chip (such as the STM32L4 series). The signal processing unit 12 and the flexible pressure sensing sheet 3 are electrically connected.
[0032] Furthermore, such as Figure 3 As shown, a display screen 4 is fixedly installed on the outside of the sensor body 1 to facilitate the staff to view real-time pressure data. Multiple control buttons 2 are installed on the top of the sensor body 1 to facilitate the staff to operate the sensor body 1.
[0033] In this embodiment, the operator inserts the flexible pressure sensing sheet 3 into the detection area between the pectus carinatum 10 and the human body, presses the control button 2, turns on the display screen 4, and views the real-time pressure data.
[0034] Furthermore, such as Figure 3 As shown, a power supply unit 14 for providing power is fixedly installed inside the sensor body 1. The power supply unit 14 uses a 100mAh rechargeable lithium battery, and the thickness of the whole package is controlled at 2-3mm to ensure a comfortable fit.
[0035] Furthermore, such as Figure 3 As shown, a Type-C charging interface 5 is fixedly installed on the outside of the sensor body 1 for charging the power supply unit 14.

[0036] Furthermore, such as Figure 3As shown, a Bluetooth module 13 is fixedly installed on the outside of the substrate 11. The Bluetooth module 13 is a low-power module that supports wireless connection with terminal devices. It adopts the BLE 5.0 protocol and establishes a connection with a mobile APP or mini-program. The pressure data acquisition frequency is set to 1Hz, and the transmission distance can reach 10m, ensuring that users can view the correction pressure value in real time. Through the mobile APP or mini-program, it connects to the backend server to upload data such as usage pressure and wearing time. The backend can authorize monitoring permissions to relevant personnel to realize remote monitoring.
[0037] Furthermore, such as Figure 1 As shown, the outer side of the sensor body 1 is provided with a waterproof and wear-resistant protective layer made of medical-grade silicone, which improves the service life of the sensor.
[0038] Specific working methods:
[0039] First, the staff fixes the magnetic base 6 and the Velcro surface 8 to the outside of the pectus carinatum 10, close to the position where pressure monitoring is required, using adhesive or other methods. Then, the magnetic patch 7 is aligned with the magnetic base 6 to fix the sensor body 1. The sensor body 1 is then gently pressed to connect the Velcro surface 8 and the Velcro hook surface 9, thus fixing the sensor body 1. Finally, the flexible pressure sensing sheet 3 is inserted into the detection area between the pectus carinatum 10 and the human body. The control button 2 is pressed to turn on the display screen 4 and view the real-time pressure data. Through the dual connection structure of magnetic and Velcro, the sensor and the orthodont can be installed and removed without damage. A single sensor can be adapted to multiple orthodonts. If damaged, only the sensor body 1 needs to be replaced, reducing the cost of use. Moreover, the combination of magnetic patch and Velcro allows for flexible adjustment of the sensing position to adapt to different models of orthodonts and different users' chest shapes, ensuring accurate pressure sampling points.
