Description

Technical Field

[0001] This utility model relates to the field of wearable patch technology, specifically a flexible anti-interference wearable patch. Background Technology

[0002] With the improvement of people's living standards and the continuous advancement of technology, various wearable devices are gradually being integrated into daily life, providing convenience for people in many aspects such as health monitoring, sports assistance, and convenient communication. Among them, wearable patches, as a type of wearable product that is in close contact with the human skin, have shown great application potential in fields such as medical care, sports and fitness, and electronic entertainment.

[0003] In the healthcare field, patch sensors are widely used to monitor physiological parameters such as heart rate, blood pressure, and body temperature. Doctors can use these patches to remotely and continuously collect patients' vital signs data, enabling them to detect health problems in a timely manner. This is particularly important for scenarios such as chronic disease management and postoperative rehabilitation monitoring.

[0004] However, existing wearable patches have gradually revealed a series of problems in actual use, seriously affecting their performance and user experience. On the one hand, most wearable patches on the market currently lack effective structural measures to shield against external interference. In daily life, various electronic devices such as mobile phones, computers, and microwave ovens generate electromagnetic radiation of different frequencies, and various medical instruments in medical settings also emit complex electromagnetic signals. These external interference sources can easily affect the normal operation of the delicate electronic components inside the wearable patch, causing problems such as inaccurate monitoring data and signal transmission interruptions. This prevents users from obtaining reliable physiological information or interactive feedback, greatly reducing the practicality and reliability of the wearable patch.

[0005] On the other hand, existing wearable patches often rely solely on an adhesive layer to hold them to the skin, making it difficult to guarantee a tight and stable fit over a long period. Once the body sweats or the patch edges are subjected to slight external force, the patch can easily lift or shift, further affecting the accuracy of the sensor's data collection, or even causing the patch to detach completely and cease functioning. Therefore, we propose a flexible, anti-interference wearable patch to address these issues. Utility Model Content

[0006] The present invention aims to solve the technical problem of unstable patch application in the prior art.

[0007] Therefore, the technical solution adopted by this utility model is as follows:

[0008] A flexible anti-interference wearable patch includes a housing with a built-in sensor covered with a metal foil. An adhesive layer is fixedly connected to the back of the housing. A connecting assembly is provided on the back of the housing, comprising two assembly cylinders placed inside the housing. The outer walls of the assembly cylinders are fixedly connected to the inner wall of the housing. A connecting ring is fixedly connected to one end of each assembly cylinder near the housing, and a rubber cap is fixedly connected to the side of the connecting ring away from the assembly cylinder. A plug seat is built into each assembly cylinder and slidably connected to the inner wall of the assembly cylinder. Multiple return springs are provided between the rubber cap and the plug seat. A suction cup is fixedly connected to the end of each assembly cylinder away from the rubber cap. A one-way valve is provided on one side of each assembly cylinder, located between the suction cup and the plug seat.

[0009] Preferably, pressing elements are fixedly connected to both sides of the housing, and the rubber cover coincides with the axis of the pressing elements.

[0010] Preferably, a wireless signal unit is fixedly connected to the top of the housing, and the input end of the wireless signal unit is electrically connected to the output end of the sensor.

[0011] Preferably, the adhesive layer surface has two communicating windows, and the end of the suction cup away from the assembly cylinder extends through the communicating windows to the outside of the housing.

[0012] Preferably, an assembly hole is provided on one side of the assembly cylinder, and the outer surface of the one-way valve is fixedly connected to the inner wall of the assembly hole.

[0013] Preferably, a plurality of fixing plates are fixedly connected to the inner ring wall of the connecting ring, and a positioning cylinder is fixedly connected to one end of the fixing plate near the plug seat, and one end of the reset spring contacts the bottom of the inner cavity of the positioning cylinder.

[0014] Preferably, the plug seat has multiple positioning grooves on the side near the rubber cover, and one end of the reset spring contacts the bottom of the positioning groove cavity.

[0015] Preferably, a fixing ring groove is formed around the plug seat, and a sealing ring is sleeved on the inner ring wall of the fixing ring groove, with the outer ring wall of the sealing ring in contact with the inner wall of the assembly cylinder.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0017] In terms of structural design, the pressing parts on both sides of the housing, the built-in sensor, and the top wireless signal unit work together. The wireless signal unit is freed from cable constraints, bringing great convenience and flexibility to real-time monitoring and data acquisition. The sensor is tightly protected by a metal foil and a metal housing. The metal shielding layer utilizes the properties of reflecting and absorbing electromagnetic waves to create a stable internal environment, effectively ensuring the accuracy and reliability of sensor data and resisting complex electromagnetic interference. The adhesive layer initiates the initial fixing process, allowing the patch to adhere to the human body simply and quickly. The assembly cylinder, rubber cover, plug seat, and return spring of the connecting components work together. Pressing the pressing parts causes the rubber cover to push the plug seat, expelling air through a one-way valve. After releasing, the return spring helps the plug seat return to its position, creating negative pressure inside the assembly cylinder, causing the suction cup to firmly adhere to the human body. This double fixation ensures that the patch remains stable even during movement, effectively preventing it from falling off. The end face that contacts the human body can closely conform to the curve of the human body. With its excellent anti-interference and stable fixing characteristics, the patch meets user needs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figures 1-5 As shown, this utility model provides a flexible anti-interference wearable patch, including a housing 1, with pressing members 101 fixedly connected to both sides of the housing 1. The housing 1 houses a sensor 103, which is a heart rate sensor used to monitor the human heart rate. A wireless signal unit 102 is installed on the top of the housing 1, which enables the patch to easily transmit data with external devices without complicated cable connections, improving the convenience and flexibility of use and facilitating real-time monitoring and data collection. The surface of the sensor 103 is covered with a metal foil 104, and an adhesive layer 105 is fixedly connected to the back of the housing 1. A connecting component 2 is provided on the back of the housing 1. In the design of this wearable patch, the metal foil 104 is used as a shielding layer to cover the surface of the sensor 103, and together with the metal housing 1, the internal electronic components (such as the sensor 103) are wrapped up. Because the metal shielding layer has the characteristics of reflecting and absorbing external electromagnetic waves, when there is electromagnetic interference of various frequencies in the outside, the metal shielding layer can block these electromagnetic waves from entering the interior of the housing 1, thereby avoiding interference with the normal operation of the sensor 103 and ensuring the accuracy and stability of the measurement data of the sensor 103.

[0026] Furthermore, two communicating windows 106 are opened on the surface of the adhesive layer 105. The connecting assembly 2 includes two assembly cylinders 201, which are placed inside the housing 1. The outer wall of the assembly cylinder 201 is fixedly connected to the inner wall of the housing 1. A connecting ring 202 is fixedly connected to one end of the assembly cylinder 201 in the housing 1. A rubber cover 203 is fixedly connected to the side of the connecting ring 202 away from the assembly cylinder 201. The rubber cover 203 coincides with the axis of the pressing member 101. A plug seat 207 is built into the assembly cylinder 201 and is slidably connected to the inner wall of the assembly cylinder 201. Multiple return springs 206 are provided between the rubber cover 203 and the plug seat 207. Multiple fixing plates 204 are fixedly connected to the inner ring wall of the connecting ring 202. A positioning cylinder 205 is fixedly connected to one end of the fixing plate 204 near the plug seat 207. One end of the return spring 206 The bottom of the inner cavity of the positioning cylinder 205 is in contact with the bottom of the positioning cylinder 207. The side of the plug seat 207 near the rubber cover 203 has multiple positioning grooves 208. One end of the return spring 206 is in contact with the bottom of the inner cavity of the positioning groove 208. The plug seat 207 has a fixing ring groove 209 around its perimeter. A sealing ring 210 is fitted into the inner ring wall of the fixing ring groove 209. The outer ring wall of the sealing ring 210 is in contact with the inner wall of the assembly cylinder 201. A suction cup 211 is fixedly connected to the end of the assembly cylinder 201 away from the rubber cover 203. The end of the suction cup 211 away from the assembly cylinder 201 extends through the connecting window 106 to the outside of the housing 1. A one-way valve 213 is provided on one side of the assembly cylinder 201. The one-way valve 213 is located between the suction cup 211 and the plug seat 207. An assembly hole 212 is provided on one side of the assembly cylinder 201. The outer surface of the one-way valve 213 is fixedly connected to the inner wall of the assembly hole 212. When the wearable patch needs to be fixed to the human body, the patch is first adhered to the appropriate position using the adhesive layer 105 to achieve initial fixation. Then, by applying force to the pressing member 101, the pressing member 101 will compress the rubber cover 203. After the rubber cover 203 is compressed, it will push the plug seat 207 to move away from the rubber cover 203 within the assembly cylinder 201. During the movement of the plug seat 207, the air between the plug seat 207 and the suction cup 211 will be squeezed out, and this air will be discharged through the one-way valve 213 located on one side of the assembly cylinder 201. When the pressing member 101 is released, the plug seat 207 returns to its original position towards the rubber cover 203 under the elastic force of the return spring 206. Since the air has been squeezed out, the return of the plug seat 207 will increase the space inside the assembly cylinder 201, and the air cannot enter in the opposite direction through the one-way valve 213, thus creating a negative pressure inside the assembly cylinder 201. This negative pressure causes the suction cup 211 to adhere tightly to the human body surface, and together with the adhesive layer 105, it achieves double fixation of the wearable patch, enhances its stability during use, and prevents the patch from falling off.

[0027] The adhesive layer 105 and suction cup 211 on the back of the shell 1 are made of flexible material. As a wearable patch, the ends that contact the human body are all designed to be flexible, so that they can better conform to the curves of the human body surface and increase the comfort of wearing.

[0028] The shielding structure composed of metal foil 104 and metal shell 1 can effectively reflect and absorb external electromagnetic waves, providing a relatively stable working environment for internal sensor 103, greatly reducing the impact of external interference on the performance of sensor 103, and is particularly suitable for working in complex electromagnetic environments, ensuring the accuracy and reliability of data acquisition.

[0029] The adhesive layer 105 and suction cup 211 are used for dual fixation. On the one hand, the adhesive layer 105 can quickly and easily fix the patch to the surface of the human body. On the other hand, the suction cup 211 formed by the pressing operation further enhances the fixation effect, so that the patch can be firmly attached to the human body and remain stable even when the human body is moving, and is not easy to fall off, thus improving the user experience.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
