Description

Technical Field

[0001] This invention relates to the field of medical monitoring technology, and in particular to a children's wristband-type wearable blood oxygen monitor. Background Technology

[0002] Blood oxygen saturation is one of the important physiological parameters reflecting human respiratory and circulatory functions, and it is widely used in clinical diagnosis and health monitoring to assess the physiological state of patients. Most existing blood oxygen monitoring devices adopt a finger clip or wrist-type structure, which obtains relevant parameters such as blood oxygen saturation and pulse rate by detecting optical signals from the human extremities.

[0003] However, existing pulse oximetry monitoring devices still have certain shortcomings in monitoring the blood oxygen levels of children, especially infants. On the one hand, children's fingers are thin, their movements are frequent, and their cooperation is low. Traditional finger clip-on pulse oximetry devices are prone to slipping or falling off during wear, leading to unstable monitoring data or even the inability to maintain continuous monitoring. On the other hand, when children are in a state of hypoperfusion (such as shock or anemia) or are engaged in vigorous activity such as crying or struggling, existing pulse oximetry monitoring devices are quite sensitive to motion interference, easily resulting in large signal fluctuations and inaccurate readings, affecting the reliability of the monitoring results.

[0004] In addition, some existing wrist-type or wearable blood oxygen monitoring devices are mainly designed for adults, and their structural size, fixation method and material comfort are difficult to adapt to the needs of children. This can easily cause discomfort when wearing them, further reduce children's wearing compliance, and is not conducive to long-term continuous monitoring.

[0005] Therefore, there is an urgent need for a wearable blood oxygen monitoring device that is structurally sound, stable to wear, and suitable for children, in order to improve the stability and reliability of blood oxygen monitoring in children with low perfusion or during activity, thereby better meeting the actual needs of children's blood oxygen monitoring. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a children's wristband-type wearable blood oxygen monitor.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A children's wristband-style wearable blood oxygen monitor includes a display module and a fixing strap. The fixing strap is connected to the display module to form a wristband structure. A fingertip monitoring component is provided on one side of the display module and is fitted onto the fingertip. A blood oxygen sensing component is provided on the fingertip monitoring component.

[0008] Preferably, the display module includes a housing and a display screen.

[0009] Preferably, the outer shell, fixing strap, connecting strap, and fingertip monitoring component are all made of skin-friendly silicone material.

[0010] Preferably, the fingertip monitoring component is made of flexible, bendable medical material to fit different children's finger shapes and improve wearing comfort.

[0011] Preferably, a button module is provided on one side of the housing. The button module is used to switch the working mode, which includes a blood oxygen monitoring mode and a fun audio-visual mode.

[0012] Preferably, the fixing strap adopts a button design for easy adjustment of tightness.

[0013] Preferably, the screen size of the display is 3-5 inches.

[0014] Preferably, the display screen is used to display one or more of the following: blood oxygen saturation value, pulse rate value, and perfusion index value, and is capable of displaying waveform information corresponding to the blood oxygen signal.

[0015] The beneficial effects of this invention are as follows: 1. High wearing stability, suitable for children. This invention forms a wristband structure with a fixing strap and a display module, and connects the fingertip monitoring component to the display module, allowing the device to be stably fixed to both the child's wrist and fingertips simultaneously. Compared to traditional single-finger clip-on blood oxygen monitoring devices, this invention can maintain relative stability of the monitoring site even when the child is crying, active, or has low cooperation, thereby reducing data fluctuations caused by displacement during monitoring.

[0016] 2. Improved monitoring reliability under low perfusion and exercise conditions. The fingertip monitoring component incorporates a blood oxygen sensor made of flexible, bendable medical materials, allowing for better conformation to the different finger shapes of children. Even when a child is in a low perfusion state or undergoing vigorous exercise, the fingertip monitoring component maintains good contact with the fingertip, contributing to improved stability and reliability of blood oxygen signal acquisition.

[0017] 3. High structural integration and excellent user comfort. The display module's shell, fixing strap, and fingertip monitoring components are made of skin-friendly flexible materials, reducing irritation to children's skin, improving wearing comfort, and making it suitable for long-term continuous use, especially for clinical monitoring or home monitoring scenarios.

[0018] 4. The information display is intuitive and easy to observe and judge. The display module is equipped with a screen that can display monitoring parameters such as blood oxygen saturation, pulse rate, and perfusion index, enabling medical staff or guardians to intuitively and in real time understand the child's physiological status and facilitate the timely detection of abnormalities.

[0019] 5. Easy to operate and suitable for pediatric medical applications. By incorporating buttons on the display module, different operating modes can be switched. The operation is simple and intuitive, facilitating quick use by medical staff or guardians and enhancing overall ease of use.

[0020] 6. Wide applicability and strong structural versatility. The invention has a simple overall structure and reasonable component combination. It does not rely on complex algorithms or precise calibration, and is suitable for the blood oxygen monitoring needs of children of different ages. It has good promotion and application value.

[0021] Figure 1 This is a schematic diagram of the structure of a children's wristband-type wearable blood oxygen monitor proposed in an embodiment of the present invention.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] In one embodiment, refer to Figure 1 A children's wristband-style wearable blood oxygen monitor includes a display module 1 and a fixing strap 3. The fixing strap 3 is connected to the display module 1 to form a wristband structure. A fingertip monitoring component 5 is provided on one side of the display module 1 and is fitted onto the fingertip. A blood oxygen sensing component 6 is provided on the fingertip monitoring component 5.

[0025] In a preferred embodiment of the present invention, the display module 1 includes a housing 8 and a display screen 2.

[0026] In a preferred embodiment of the present invention, the outer shell 8, the fixing strap 3, the connecting strap 4, and the fingertip monitoring component 5 are all made of skin-friendly silicone material. The skin-friendly silicone material has good softness and elasticity, and can conform to the curved shape of a child's wrist and fingertips during wear, reducing discomfort caused by prolonged wear or localized pressure.

[0027] Because silicone has good biocompatibility and aging resistance, it can effectively reduce the risk of skin irritation for children, making it suitable for long-term or repeated use by children. At the same time, silicone has a certain degree of anti-slip property, which helps maintain stable contact between the device and the skin when children are active, crying, or making large movements, thereby improving overall wearing stability.

[0028] Furthermore, the outer shell, fixing strap, connecting strap, and fingertip monitoring component, all made of skin-friendly silicone, ensure softness and comfort while providing necessary support and protection for the internal structure. This allows the blood oxygen sensing component to maintain a relatively stable position during operation, improving the reliability of blood oxygen signal acquisition. Through the selection of these materials, the invention effectively enhances wearing comfort, safety, and monitoring stability.

[0029] In a preferred embodiment of the present invention, the fingertip monitoring component 5 is made of flexible, bendable medical material to fit different children's finger shapes and improve wearing comfort.

[0030] In a preferred embodiment of the present invention, a button module 7 is provided on one side of the outer casing 8. The button module 7 is used to switch the working mode to meet the different needs of children's blood oxygen monitoring and use.

[0031] In this embodiment, the operating modes include at least a blood oxygen monitoring mode and a child-friendly audiovisual mode. When the device is in blood oxygen monitoring mode, the blood oxygen sensor in the fingertip monitoring component collects blood oxygen parameters from the child's fingertip, and the display module displays the collected blood oxygen saturation, pulse rate, or perfusion index on the display screen, so that medical staff or guardians can understand the child's physiological status in real time.

[0032] When switching to the child-friendly audiovisual mode via button module 7, the display module outputs images or animations suitable for children to watch on the screen, accompanied by sound or visual cues to attract children's attention, alleviate their tension or resistance, and thus improve their cooperation in wearing and monitoring the device. In this mode, the child-friendly audiovisual feedback helps reduce children's crying or physical activity, indirectly improving the stability of the blood oxygen monitoring process.

[0033] By setting up button module 7 to switch working modes, the device can maintain a simple structure while taking into account blood oxygen monitoring function and child-friendly user experience, making it suitable for actual use needs in different monitoring scenarios.

[0034] In a preferred embodiment of the present invention, the fixing strap 3 adopts a button design, which facilitates adjustment of tightness.

[0035] In a preferred embodiment of the present invention, the screen size of the display screen 2 is 3-5 inches.

[0036] In a preferred embodiment of the present invention, the display screen 2 is used to display one or more of the following: blood oxygen saturation value, pulse rate value, and perfusion index value, and can display waveform information corresponding to the blood oxygen signal.

[0037] The wearable blood oxygen monitor for children described in this invention uses a strap to fix the display module to the child's wrist, ensuring that the display module is stably worn on the child's body.

[0038] A fingertip monitoring component is connected to one side of the display module. The fingertip monitoring component is designed to be fitted onto the fingertip of a child. In use, the fingertip monitoring component is fitted onto the child's fingertip, ensuring it adheres closely to the child's skin.

[0039] The fingertip monitoring component contains a blood oxygen sensor. When in operation, this sensor emits detection light towards the fingertip and receives the light signal reflected or transmitted through the fingertip tissue, thereby acquiring physiological signals related to blood oxygen saturation. The collected signals are transmitted to a display module for processing, generating corresponding blood oxygen monitoring parameters.

[0040] The display screen in the display module is used to display one or more of the monitored blood oxygen saturation values, pulse rate values, and perfusion index values, so that medical staff or guardians can intuitively observe the child's physiological state.

[0041] Because the fingertip monitoring component and the display module are stably connected through the wristband structure, and the fingertip monitoring component is made of flexible and bendable medical materials, the fingertip monitoring component can still stably fit the fingertip when the child is in a low perfusion state or is crying or engaging in strong movements, thereby improving the stability of blood oxygen signal acquisition and reducing the fluctuation of monitoring data caused by the child's activities.

[0042] When function switching is required, press the button module located on the display module housing. The button module is used to switch between different working modes to meet the needs of blood oxygen monitoring and related usage. Through the coordinated work of the display module and the fingertip monitoring component, continuous and stable monitoring of children's blood oxygen parameters can be achieved.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
