Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a flexible biosensing monitoring dressing that can adapt to fit. Background Technology

[0002] In recent years, the development of flexible electronics technology has spurred numerous designs for flexible electronic skin or patches. However, these studies typically focus on making the sensing unit itself flexible, such as using stretchable conductors or thin-film transistors, but fail to effectively reconcile the core contradiction between "adaptive fit in dynamic environments" and "high-fidelity signal acquisition" at the overall system architecture level. More specifically, existing solutions generally lack a sophisticated integrated structural design. While some research on flexible electronic skin or patches has emerged, it largely focuses on the flexibility of the sensing unit itself, without addressing the contradiction between "dynamic adaptive fit" and "high-quality signal acquisition" at the system level. Specifically, current technology lacks an integrated structure capable of adjusting its own mechanical state in real time and imperceptibly during daily human activities such as breathing, joint flexion and extension, and muscle deformation, maintaining conformal contact with the skin, and ensuring relatively stable positioning of the internal sensing unit. This results in insufficient reliability of monitoring signals in dynamic environments, limiting its application in long-term, continuous health monitoring and precision medicine. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an adaptive, flexible biosensing monitoring dressing.

[0004] The objective of this invention can be achieved through the following technical solution: A flexible biosensing monitoring dressing that can adapt to fit includes an adaptive dressing, a detection component, and an edge filling dressing. The adaptive dressing has a multi-layer structure, the detection component is located in the multi-layer structure of the adaptive dressing, and several edge filling dressings are provided, with the several edge filling dressings arranged in a circumferential array on the side of the adaptive dressing.

[0005] Furthermore, the adaptive dressing includes an adhesive layer, a regulating layer, and a composite layer, with the adhesive layer, stabilizing layer, and sealing layer connected in sequence. A fitting box is provided on the composite layer, and a detection component is disposed in the fitting box.

[0006] Furthermore, the Young's modulus of the composite layer is in the range of 0.1 kPa to 100 kPa, and increases nonlinearly with increasing strain.

[0007] Furthermore, the composite layer and the control layer are partially connected through a pre-stretching and bonding process.

[0008] Furthermore, the adhesive layer, the regulating layer, and the composite layer are all provided with replenishment grooves of the same size.

[0009] Furthermore, all of the aforementioned supplementary slots are trapezoidal in shape.

[0010] Furthermore, the detection component is composed of one or more combinations of dry electrodes, impedance sensors, temperature sensors, strain sensors, and chemical sensors.

[0011] Furthermore, the detection component is disposed between the composite layer and the control layer.

[0012] Furthermore, the edge filling dressing is respectively disposed in the corresponding plurality of replenishment slots.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By designing a heterogeneous structure of "adhesive layer, regulating layer, and composite layer" with a specific stiffness gradient, the mechanical properties of the dressing are highly matched with those of the skin. The regulating layer acts as a "mechanical buffer," absorbing most of the dynamic deformation energy, resulting in minimal stress on the outermost composite layer, especially on brittle electronic components, thus achieving a non-destructive and stable fit under strenuous human activity.

[0014] 2. Extremely high signal acquisition quality: The detection components are firmly fixed, ensuring the relative position of the sensing interface and the skin is stable, thus guaranteeing the accuracy and reliability of the signal in dynamic environments.

[0015] 3. Powerful functional integration and expansion capabilities: The rigid encapsulation shell serves as the core of the function, while the large surrounding flexible area ensures a snug fit. This design facilitates modular replacement and functional upgrades, and can adapt to different application scenarios, from simple ECG monitoring to multi-parameter physiological and biochemical signal monitoring.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0020] Specific implementation method one: Combining Figures 1 to 3 This embodiment describes an adaptive, flexible biosensing monitoring dressing comprising an adaptive dressing 1, a detection component 2, and edge-filling dressings 3. The adaptive dressing 1 has a multi-layered structure, with the detection component 2 located within the multi-layered structure. Several edge-filling dressings 3 are arranged in a circumferential array on the side of the adaptive dressing 1. In use, the user attaches the adaptive dressing 1 to the chest or forearm. When the joint is bent, the skin is stretched. At this time, the bottom layer of the adaptive dressing 1 deforms synchronously with the skin, the middle layer of the adaptive dressing 1 undergoes significant compression and shear deformation, absorbing most of the strain energy, while the top layer of the adaptive dressing 1 undergoes only a small deformation. This ensures that the contact interface between the detection component 2 and the skin remains stable, effectively suppressing motion artifacts. The acquired biosignals are amplified, filtered, and digitized within the detection component 2, completing the signal conversion during the motion process, effectively ensuring the wide applicability of the dressing.

[0021] Specific Implementation Method Two: Combining Figures 1 to 3 This embodiment describes an adaptive dressing 1 comprising an adhesive layer 11, a regulating layer 12, and a composite layer 13. The adhesive layer 11, the stabilizing layer 12, and the sealing layer 13 are connected sequentially. A fitting box 14 is provided on the composite layer 13, and the detection component 2 is disposed in the fitting box 14. The regulating layer 12 is made of silicone foam with a Young's modulus of approximately 5 kPa, a thickness of approximately 1.5 mm, and a porosity of approximately 85%. Its modulus increases nonlinearly to over 50 kPa when the compression rate exceeds 30%, thereby providing support during severe deformation. The adhesive layer 11 is coated with a medical acrylic hydrogel pressure-sensitive adhesive with a thickness of approximately 200 μm on the lower surface of the regulating layer 12, and the surface is covered with release paper for use, ensuring the adhesiveness of the dressing during use.

[0022] Specific implementation method three: Combining Figures 1 to 3 This embodiment describes a composite layer 13 whose Young's modulus is in the range of 0.1 kPa to 100 kPa and increases nonlinearly with increasing strain, thus ensuring the material consistency of the adaptive dressing 1.

[0023] Specific implementation method four: Combination Figures 1 to 3In this embodiment, the composite layer 13 and the control layer 12 are partially connected by a pre-stretching and bonding process to increase the connection strength and ensure the fitting effect of the device.

[0024] Specific Implementation Method Five: Combining Figures 1 to 3 In this embodiment, the adhesive layer 11, the regulating layer 12, and the composite layer 13 are all provided with replenishment grooves 15 of the same size. By providing multiple replenishment grooves 15, it is possible to add edge filling dressing 3 after the dressing is attached to the user's skin to compensate for stress. When the user uses the dressing, the dressing has the effect of adaptively fitting the position and moving state.

[0025] Specific Implementation Method Six: Combination Figures 1 to 3 In this embodiment, the multiple replenishing slots 15 are all trapezoidal. The stress generated by the movement of the center of the adaptive dressing 1 is transmitted to the outside of the adaptive dressing 1 through the inclined side of the trapezoidal shape, so as to receive more stress. This allows the stress to be compensated by the edge filling dressing 3, so that the adaptive dressing 1 can adapt to a wider range of forces during the user's movement, that is, it can adapt to the large range of movement and high speed of the user's movement.

[0026] Specific implementation method seven: Combination Figures 1 to 3 This embodiment describes a detection component 2 that consists of one or more combinations of a dry electrode, an impedance sensor, a temperature sensor, a strain sensor, and a chemical sensor, employing existing technology to achieve real-time monitoring of the corresponding indicators.

[0027] Specific implementation method eight: Combination Figures 1 to 3 In this embodiment, the detection component 2 is disposed between the composite layer 13 and the control layer 12, and the detection component 2 is protected by the control layer 12 and the composite layer 13.

[0028] Specific Implementation Method Nine: Combining Figures 1 to 3 In this embodiment, the edge filling dressing 3 is respectively disposed in the corresponding plurality of replenishment grooves 15. The edge filling dressing 3 is made of porous material. The plurality of edge filling dressings 3 and the adaptive dressing 1 perform stress integration, making the dressing more durable.
