[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Heatstroke or heat stroke is a serious and fatal illness caused by prolonged exposure to high temperatures and humidity, leading to an imbalance in the body's temperature regulation function, resulting in heat production exceeding heat dissipation. This can cause a rapid rise in core temperature, even exceeding 40°C, accompanied by impaired consciousness (such as delirium, convulsions, and coma) and multiple organ dysfunction. The primary cause of heatstroke or heat stroke is the patient's inability to foresee the possibility of heatstroke or even heat stroke before the onset of the disease, resulting in continued heat exposure. However, related technologies struggle to provide real-time monitoring and early warning of workers' physical condition in high temperatures, creating safety risks.

[0029] Based on this, the embodiment of the present invention provides a heat stroke warning device and system to perform real-time detection and warning of the physical condition of workers under high temperatures, and promptly remind workers, thereby reducing safety hazards.

[0030] To facilitate understanding of this embodiment, firstly, a heat stroke warning device disclosed in the embodiment of the present utility model is introduced, see Figure 1 A schematic diagram of a heatstroke warning device is shown, which includes: a sweat belt and a temperature measuring probe; wherein, a collection unit 10 is provided at the first designated position inside the sweat belt, a first audio unit 11 is provided at the second designated position, a second audio unit 12 is provided at the third designated position, and a Bluetooth unit 13 is provided at the fourth designated position; the collection unit 10, the first audio unit 11, the second audio unit 12 and the temperature measuring probe are all communicatively connected with the Bluetooth unit 13; the temperature measuring probe is used to collect the user's core body temperature signal and send the core body temperature signal to the Bluetooth unit 13; the collection unit 10 is used to collect the user's physiological signal and send the physiological signal to the Bluetooth unit 13; the Bluetooth unit 13 is used to generate a warning prompt signal when it is confirmed that the physiological signal and / or the core body temperature signal exceed their respective corresponding preset thresholds; the first audio unit 11 and the second audio unit 12 are used to play the warning prompt signal.

[0031] The above-mentioned sweat guide belt is usually in the shape of a long and thin strip and can be worn on the user's head; the above-mentioned first designated position can be set according to actual needs. Preferably, in order to ensure the accuracy of physiological signal collection, the first designated position can be selected from the middle position of the sweat guide belt, that is, the collection unit 10 can be set in the middle position of the sweat guide belt; the above-mentioned second designated position can be located at one end of the sweat guide belt, and the third designated position is located at the other end of the sweat guide belt, such as the left side in the length direction of the sweat guide belt corresponds to the second designated position, and the right side in the length direction of the sweat guide belt corresponds to the third designated position, that is, the first audio unit 11 and the second audio unit 12 can be respectively set on the left and right sides of the sweat guide belt.

[0032] The above-mentioned temperature measuring probe can be an in-ear temperature measuring probe, which can measure the temperature inside the human ear canal to measure the user's core body temperature signal and send the collected core body temperature signal to the Bluetooth unit 13. The collection unit 10 can collect the user's physiological signals, such as heart rate, and send the collected physiological signals to the Bluetooth unit 13. The Bluetooth unit 13 usually pre-stores a physiological signal threshold and a core body temperature signal threshold. The collected physiological signal can be compared with the physiological signal threshold, and the received core body temperature signal can be compared with the core body temperature signal threshold to obtain a comparison result. When the comparison result indicates that the core body temperature signal exceeds the core body temperature signal threshold, or the physiological signal exceeds the physiological signal threshold, or both the core body temperature signal and the physiological signal exceed their respective corresponding thresholds, a corresponding warning prompt signal can be generated, such as a prompt that the heart rate is too fast, the body temperature is too high, etc., and the warning prompt signal is sent to the first audio unit 11 and the second audio unit 12. The first audio unit 11 and the second audio unit 12 can play the warning prompt signal to the user in voice. This embodiment uses two audio units, which are respectively arranged at the two ends of the sweat-conducting band to achieve a stereo effect.

[0033] The above-mentioned heat stroke warning device can detect and warn the user's physical condition in real time. Moreover, since the sweat belt can be worn on the user's head, the warning signal can be promptly prompted to the user, thereby reducing the safety risks of heat stroke or heat stroke in the user.

[0034] Furthermore, the collection unit 10 includes a sampling chip; the collection unit 10 collects the user's physiological signals through the sampling chip; the sampling chip and the outer shell of the sweat belt are sealed with sealant.

[0035] In the related art, a layer of transparent film is usually added to the collection unit 10 to protect the collection unit 10 from the influence of sweat, but the transparent film will interfere with the sampling process and affect the accuracy of sampling; in this embodiment, the collection unit 10 includes a sampling chip, and does not adopt a transparent film structure. Instead, a sealant is used to seal the gap between the sampling chip and the outer shell of the sweat guide belt to fix the sampling chip and make the sampling chip flush with the surface of the outer shell, thereby avoiding the interference problem caused by the transparent film and improving the accuracy of collecting the user's physiological signals.

[0036] Furthermore, a flexible circuit board is provided inside the sweat guide band; the collection unit 10, the first audio unit 11, the second audio unit 12 and the Bluetooth unit 13 are all provided on the flexible circuit board.

[0037] A flexible printed circuit board (FPCB) is a highly reliable, flexible printed circuit board made from polyimide or polyester film. It features high wiring density, light weight, thinness, and excellent bendability. This embodiment utilizes a FPCB structure, allowing the sweatband to bend at various angles to accommodate different head shapes without damaging the sweatband.

[0038] Furthermore, the sweat guide belt is provided with a first indicator light, a second indicator light and a battery; when the battery is in the charging state, the first indicator light is on; when the battery is fully charged, the first indicator light and the second indicator light are both on; when the Bluetooth connection state of the Bluetooth unit 13 is waiting for connection, the second indicator light flashes at a first frequency; when the Bluetooth connection state of the Bluetooth unit 13 is successfully connected, the second indicator light remains on for a preset time period; when the sweat guide belt is in normal working state, the second indicator light flashes at a second frequency.

[0039] The first frequency and the second frequency can be set according to actual needs, and the second frequency is usually lower than the first frequency; the preset time period can be set as needed, and is usually a shorter period of time, such as 5 seconds, 10 seconds, etc.; the first indicator light and the second indicator light can be selected according to actual needs, for example, the first indicator light can be a red indicator light, and the second indicator light can be a blue indicator light, etc. For the convenience of explanation, taking the first indicator light being a red indicator light and the second indicator light being a blue indicator light as an example, the red indicator light can be used to indicate the charging status, and the blue indicator light can indicate the working status of the heat stroke warning device. Specifically, during the charging process of the battery of the sweat guide belt, the red indicator light is on, indicating that it is charging. Charging, when the battery is not charged, the red indicator light is off, for example, when the charging port corresponding to the battery is plugged into the charging cable to charge the battery, the red indicator light turns on; when the charging cable is unplugged from the charging port, the red indicator light turns off; when fully charged, the red indicator light and the blue indicator light are always on; when the blue indicator light flashes at a first frequency, it indicates that the Bluetooth connection status of the Bluetooth unit 13 is waiting for connection; when the Bluetooth connection is successful, the blue indicator light remains on for 10 seconds and then goes out; the blue indicator light can be converted to a breathing light state, that is, it flashes at a second frequency, indicating that the sweat guide belt is working and in normal working condition. In specific implementation, the display status of the blue indicator light can be adjusted by the Bluetooth unit 13.

[0040] Furthermore, the sweat-conducting band includes a first shell 14 and a second shell 15; the connecting surfaces between the first shell 14 and the second shell 15 are both flat, and the first shell 14 and the second shell 15 are bonded by a silicone adhesive.

[0041] The above-mentioned silicone adhesive is usually made of environmentally friendly material; in the related art, the two shells of the sweat-conducting belt are usually provided with grooves or protrusions, and the two shells are assembled according to the positions of the grooves or protrusions. This assembly method is relatively cumbersome and has low assembly efficiency; in this embodiment, the connecting surfaces between the first shell 14 and the second shell 15 are both set to planes, and silicone adhesive is applied to the corresponding positions of the connecting surfaces on the first shell 14 or the second shell 15, and then docked with the corresponding positions of the connecting surfaces on the other shell. After heating for 5 minutes, the bonding of the first shell 14 and the second shell 15 can be completed.

[0042] Furthermore, the middle portion of the first shell 14 is in an arched shape, which is used to guide the user's sweat to the side of the sweat band; wherein, when the user wears the sweat band, the first shell 14 is a shell away from the user.

[0043] In this embodiment, when the user wears the sweat guide belt, the structure of the first shell 14 located on the outside is optimized. Specifically, the middle part of the first shell 14 is designed to be an outwardly protruding arch structure. When the user's sweat flows to the upper side surface of the sweat guide belt at the corresponding position of the arch structure, due to the wider width of the upper side surface, the sweat will be guided to the side of the sweat guide belt, preventing the sweat from flowing down from the front.

[0044] like Figure 2 A front view of a heat stroke warning device shown; Figure 3 A rear view of a heat stroke warning device shown; Figure 4 A top view of a heat stroke warning device as shown; Figure 5 A bottom view of a heat stroke warning device shown; Figure 6 A left view of a heat stroke warning device shown in FIG. Figure 7 A right view of a heat stroke warning device shown in FIG. Figure 8 A three-dimensional schematic diagram of a heat stroke warning device is shown. As can be seen from the above figure, the middle part of the second shell of the heat stroke warning device is arched, which can guide sweat to the side of the sweat-guiding belt; the outer surface of the second shell is flat, which can ensure that it fits the user's head.

[0045] Furthermore, the surface of the first shell 14 and the surface of the second shell 15 are both sprayed with tactile oil.

[0046] Tactile oil is a kind of grease that can make the hand feel comfortable, delicate and smooth. It can play the role of matting, preventing dust, fingerprints and sweat. By spraying tactile oil on the first shell 14 and the second shell 15, the sweat guide belt can have a better feel and maintain a better cleanliness.

[0047] Furthermore, the first shell 14 and the second shell 15 are both made of food-grade silicone.

[0048] Food-grade silicone is a non-toxic, odorless, chemically stable inorganic polymer colloid material. It exhibits excellent transparency, tear strength, thermal stability, weather resistance, and high-temperature resistance up to 250°C. Food-grade silicone is soft, elastic, resistant to kinking and deformation, cracking, long-lasting, and resistant to cold and high temperatures. In this embodiment, both the first shell 14 and the second shell 15 are made of food-grade silicone, which is safe, pollution-free, and will not cause allergic reactions in the wearer.

[0049] In addition, in this embodiment, the standby time of the sweat guide belt is better, which can reach 11 hours or longer; according to the working status of each power-consuming module (such as the first audio unit 11, the second audio unit 12, the collection unit 10, etc.), it can be determined whether to power on the corresponding power-consuming module. For example, when the Bluetooth unit 13 is performing a Bluetooth connection, the first audio unit 11 and the second audio unit 12 will not work. At this time, the first audio unit 11 and the second audio unit 12 can be powered off. Later, when the first audio unit 11 and the second audio unit 12 are needed to play the early warning prompt signal, the first audio unit 11 and the second audio unit 12 are powered on, which saves energy consumption and extends the standby time.

[0050] In addition, there are two connection holes designed at both ends of the sweat guide belt, and the two connection holes are connected by a headband. When the user wears the sweat guide belt on the head, the wearing stability can be improved by adjusting the headband, avoiding problems such as the sweat guide belt falling off during exercise.

[0051] This device can detect the core body temperature signals and physiological signals of the human body, such as core body temperature and heart rate values, and combine them with clinical guidelines for early warning of heat stroke to form an early warning algorithm for heat stroke and heat stroke, obtain evaluation indicators such as the heat tolerance index, and judge the user's status based on the evaluation criteria, and divide it into three levels: mild heat stroke risk, moderate heat stroke risk, and heat stroke risk.

[0052] This device can use voice broadcasts to remind users based on the risk assessment results. For example, if the heart rate is >180 and the body temperature is higher than 38.5℃, the risk of heat stroke is confirmed and the user can be notified of the risk.

[0053] The above-mentioned heatstroke warning device is a wearable device that can work stably in high temperature and high humidity environments. It can be used by people working or training in high temperature and high humidity environments. It can monitor the human body's core body temperature, heart rate and other indicators in real time, and obtain parameters such as heat index that have predictive capabilities for the occurrence of heatstroke or heatstroke through built-in related modules and big data algorithms. It can promptly issue warning signals that heatstroke or heatstroke is about to occur, thereby warning of the risk of heatstroke or heatstroke.

[0054] This embodiment further provides a heat stroke warning system, comprising: a host computer and any one of the heat stroke warning devices described above; there are multiple heat stroke warning devices; the host computer is communicatively connected to a Bluetooth unit in each heat stroke warning device;

[0055] The host computer is used to receive the physiological signal and core body temperature signal sent by the Bluetooth unit in each heat stroke warning device, as well as the identification information of the sweat belt in the heat stroke warning device, process the physiological signal, core body temperature signal and identification information, and obtain a processing result;

[0056] The processing results include: the physiological signal trend prediction results and core body temperature signal trend prediction results of the user corresponding to each identification information; the physiological signal statistical results and core body temperature signal statistical results of users corresponding to different identification information.

[0057] The host computer can simultaneously communicate with multiple heatstroke warning devices, meaning it can simultaneously monitor the physical conditions of multiple users and implement centralized monitoring. In this embodiment, the Bluetooth unit in each heatstroke warning device can transmit received physiological signals and core body temperature signals to the host computer, and also transmit the identification information of the sweatband in the heatstroke warning device to the host computer. Different sweatbands typically have different identification information, and the corresponding sweatband can be accurately identified using this identification information. The host computer can perform trend predictions based on the physiological information obtained for each user wearing the sweatband, obtaining a physiological information trend prediction result for the user; perform trend predictions based on the core body temperature signal obtained for the user, obtaining a core body temperature signal trend prediction result for the user; and provide early warnings based on the physiological information trend prediction results and the core body temperature signal trend prediction results. Furthermore, statistics can be collected on the physiological signals of different users to obtain physiological signal statistics; and statistics can be collected on the core body temperature signals of different users to obtain core body temperature signal statistics.
