Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a nighttime epilepsy alarm device for children. Background Technology

[0002] Children experiencing nocturnal epileptic seizures are sometimes difficult for parents to detect in time, leading to missed opportunities for optimal intervention and seriously impacting their child's health and safety. Existing epilepsy alarm devices are mostly manual monitoring or wearable devices, typically requiring parents to monitor or wear them constantly. These devices are complex to operate and easily limited by external environments or the child's activities, making it impossible for parents to continuously monitor their child's health in a simple and comfortable way. Traditional alarm systems generally have the following problems: 1. Existing wearable epilepsy monitoring devices typically rely on wristbands or headbands with batteries and sensors, which not only affects the child's sleep quality but also requires frequent charging and maintenance; 2. Existing devices generally rely on motion sensors, which may fail to capture seizure signals in time when symptoms are mild or during non-strenuous activity, resulting in delayed or missed alarms; 3. Most traditional devices require manual operation or periodic checks, making them unsuitable for long-term continuous monitoring during nighttime sleep. Utility Model Content

[0003] The purpose of this invention is to provide a nighttime epilepsy alarm device for children, in order to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A nighttime epilepsy alarm device for children includes a monitoring and alarm layer, with a detachable and washable layer connected above the monitoring and alarm layer; a sandwich layer is provided between the top and bottom surfaces of the monitoring and alarm layer, and a control module, an alarm module, and densely distributed pressure sensing modules are provided in the sandwich layer; an intensity adjustment switch and a power supply module are also provided outside the monitoring and alarm layer, and the power supply module, intensity adjustment switch, control module, pressure sensing module, and alarm module are connected by wires.

[0006] In a further embodiment, the pressure sensing module includes substrates fixed to the top and bottom of the interlayer and facing each other, a pressure spring is provided between the upper and lower substrates, the top and bottom of the pressure spring are fixed to the upper and lower substrates respectively, and a rangefinder is fixed in the center of one of the substrates.

[0007] In a further embodiment, the pressure sensing modules are evenly distributed in the interlayer, while the control module and alarm module are located at the edge of the interlayer.

[0008] In a further embodiment, Velcro is fixed to the four perimeters of the top surface of the monitoring alarm layer and the bottom surface of the removable washing layer, and the monitoring alarm layer and the removable washing layer are detachably connected to each other by Velcro.

[0009] In a further embodiment, several elastic cable ties are fixed to both sides of the washable layer.

[0010] Preferably, the unit density of the pressure sensing module is 200-300 units per square meter.

[0011] Preferably, the control module uses an STM32 series embedded microprocessor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] I. This utility model, by embedding multiple pressure sensing modules within the mattress, enables continuous pressure monitoring around the clock. It provides continuous monitoring during children's sleep, reducing the burden of supervision for parents. The pressure sensing modules can monitor changes in children's body movements in real time. When a child experiences an epileptic seizure, the abnormal body movements will trigger the pressure sensing modules. After filtering and analysis by the control module, a signal is transmitted to the alarm module to issue an alarm. This automated monitoring and alarm system eliminates manual operation and can promptly and effectively identify epileptic seizures in children at night, avoiding missing the best opportunity for emergency treatment.

[0014] Second, this utility model uses a mattress design, which is more in line with the ergonomics of children's sleep compared to traditional wearable detection devices, thus providing children with a good sleep experience during nighttime epilepsy monitoring. Attached Figure Description

[0019] 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.

[0020] Implementation, for example Figure 1-3 As shown, this embodiment provides a nighttime epilepsy alarm device for children, including a monitoring and alarm layer 1, with a detachable washable layer 2 connected above the monitoring and alarm layer 1. A sandwich layer 3 is provided between the top and bottom surfaces of the monitoring and alarm layer 1. The sandwich layer 3 houses a control module 4, an alarm module 5, and densely distributed pressure sensing modules 6. An intensity adjustment switch 7 and a power supply module are also located outside the monitoring and alarm layer 1. The power supply module, intensity adjustment switch 7, control module 4, pressure sensing modules 6, and alarm modules 5 are connected by wires. The pressure sensing modules 6 are evenly distributed in the sandwich layer 3, while the control module 4 and alarm modules 5 are located at the edges of the sandwich layer 3. The power supply module can be a battery or an external power source. The pressure sensing modules 6 collect pressure information from the mattress during the child's sleep. The control module 4 summarizes and analyzes the pressure information collected by the pressure sensing modules 6 to determine whether to send an alarm signal to the alarm module 5. The alarm module 5 can be a high-volume speaker. The intensity adjustment switch 7 adjusts the threshold for the alarm signal issued by the control module 4 and also functions as a main power switch. This embodiment uses multiple pressure sensing modules 6 densely embedded in the mattress to monitor the child's body movement changes in real time. When a child has an epileptic seizure, the abnormal body movement will generate abnormal pressure on the mattress that is different from that during normal sleep. These pressures can be recorded by the pressure sensing modules in the mattress and aggregated to the control module 4 for analysis to determine whether an alarm threshold has been reached. When the threshold is reached, an alarm signal is triggered and an alarm is issued. This automated monitoring and alarm system eliminates the need for manual operation and can identify epileptic seizures in a timely and effective manner at night, avoiding missing the best time for emergency treatment.

[0021] The pressure sensing module 6 includes base plates 8 fixed to the top and bottom of the interlayer 3 and facing each other. A pressure spring 9 is provided between the upper and lower base plates 8, with the top and bottom of the pressure spring 9 fixed to the upper and lower base plates 8 respectively. A rangefinder 10 is also fixed in the center of one of the base plates 8. The rangefinder 10 can be a laser rangefinder or an acoustic rangefinder, etc. The unit density of the pressure sensing module 6 is 200-300 units per square meter, preferably 225 units. This embodiment, combined with the precise structural design of the pressure spring 9 and the rangefinder 10, can accurately analyze pressure changes on the mattress. Moreover, the density of the pressure sensing modules 6 in the mattress is as high as 200-300 units per square meter, ensuring that the mattress can comprehensively and evenly monitor the child's body movements on the bed. Even if the child has a slight twitch on the bed, the sensor can effectively detect it, ensuring no omissions.

[0022] The monitoring alarm layer 1 and the bottom of the removable and washable layer 2 are fixed with Velcro 11 around their perimeters. The monitoring alarm layer 1 and the removable and washable layer 2 are connected to each other by Velcro 11 or snap fasteners. Several elastic cable ties 12 are fixed to both sides of the removable and washable layer 2. This embodiment uses an ergonomic mattress design to provide a good sleep experience for children. The Velcro 11 allows the removable and washable layer 2 to be quickly removed from the monitoring alarm layer 1, making it convenient for parents to clean and replace it. This ensures the hygiene and longevity of the device without affecting the monitoring alarm layer 1. The elastic cable ties 12 make it easy to fix the mattress to the bed and prevent the mattress from deforming or shifting due to body twisting during sleep.

[0023] In use, first lay the mattress on the bed and secure it with elastic straps 12, then let the child sleep on the bed. After the child is lying flat and quiet, power on the monitoring and alarm layer 1. At this time, the control module 4 will record the status as the initial state and then start recording the information sent by the pressure sensing module 6 when the child is sleeping. When the child has an epileptic seizure, the shaking and convulsions of the body or limbs during the seizure will cause the pressure sensing module 6 to generate continuous abnormal pressure changes. These changes are sent to the control module 4 for recording and analysis, and the control module 4 determines whether to send an alarm signal to the alarm module 5 based on the threshold set by the sensing intensity adjustment switch 7. Note that the threshold and the data calculated by the control module 4 can be the maximum number of pressure changes of each pressure sensing module 6 per unit time. When the set threshold is reached, the control module 4 will trigger the alarm module 5 to notify the parents to take emergency measures for the child in time. The signal analysis and processing and command sending process in the control module 4 are similar to the process shown in CN213045620U.

[0024] In summary, this invention presents an innovative nighttime epilepsy alarm device for children. The mattress integrates efficient pressure sensing technology, intelligently monitoring the child's sleep state. When an epileptic seizure occurs, it can immediately issue an alarm signal to notify parents or guardians to take timely emergency measures, reducing the health risks associated with epileptic seizures. Combining ease of use, comfort, and efficiency, it is an intelligent health monitoring device suitable for home use, providing a convenient and safe monitoring method for children and patients with long-term epilepsy.
