Description

Technical Field

[0001] The present invention relates to the field of heat stroke, and in particular to a heat stroke monitoring device and a use method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] When exposed to a high temperature environment, heat dissipation is limited, and heat production is excessive, the core body temperature will rise. When the core temperature exceeds 40°C and is accompanied by related central nervous system dysfunction and multiple organ failure, it is called heat stroke. According to the cause, heat stroke can be divided into non-exertional or exertional. Non-exertional usually occurs in older people due to exposure to hot environments and insufficient heat dissipation; exertional is mainly related to physical activity, which produces heat that cannot be dissipated in time, leading to an increase in core temperature. When the body temperature rises, the body's metabolic rate increases, and oxygen consumption increases accordingly. The patient will experience increased breathing and tachycardia, the oxidative phosphorylation process in the body begins to uncouple, and multiple enzymes stop working. Cytokine-mediated systemic inflammatory response will occur, and heat shock protein production will increase. Blood is shunted from the visceral circulation to the skin and muscles, leading to gastrointestinal ischemia and increased intestinal mucosal permeability. Hepatocytes, vascular endothelium, and neural tissue are most sensitive to increases in core temperature, and these organs will be damaged. In severe cases, patients will experience multiple organ and system failure and disseminated intravascular coagulation.

[0004] The diagnosis of heat stroke is largely based on the clinical triad: abnormalities of the nervous system, recent exposure to hot weather or physical exertion. For outdoor workers, they must have the characteristics of exposure to hot weather and physical exertion. The most common symptoms of heat stroke are: tachycardia, tachypnea, and hypotension. When the nervous system of heat stroke patients is damaged, clinical manifestations include behavioral changes, confusion, delirium, convulsions, dizziness, agitation, aggression, slurred speech, nausea and vomiting. The most direct manifestations are: fever, impaired consciousness, stiff limbs and twitching (shaking), and stiff fingers like "chicken claws". This is the early stage of heat stroke. If only the body temperature of outdoor workers is monitored to judge heat stroke, there will be deviations, because working outdoors, sun exposure and changes in outdoor temperature may cause misjudgment of temperature monitoring, so only monitoring body temperature is far from enough. Therefore, it is necessary to monitor other symptoms in the early stages of heat stroke. The "chicken claw-like" fingers mentioned above refer to stiff hands that are uncontrollably straightened and unable to bend the knuckles, with the fingers crossed. This symptom begins at the early stages of heat stroke and continues to accompany the disease. For patients with twitching symptoms, the initial stage is trembling or inconspicuous twitching, which most people mistake for muscle fatigue and ignore. As the disease worsens, large-scale twitching will occur. Therefore, based on the above characteristics, a heat stroke monitoring device and a method of using the device are needed. Summary of the invention

[0028] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0029] The present invention is a heat stroke monitoring device and a method of using the same. Before describing the device as a whole, the application of the device is briefly described. Since the device is used to monitor heat stroke, there are two main application scenarios: one is outdoor workers and the other is patients receiving treatment in hospitals. Once the symptoms of patients receiving treatment worsen, the body will still experience involuntary twitching, and the fingers will also become stiff and appear "chicken claw-like". For the above two, the structures of the devices are essentially the same, and the specific subtle differences will be described in particular. The following is the specific structure of the device:

[0030] It includes a finger monitoring component 1 and a limb monitoring component 2;

[0031] As shown in the attached figure of the instruction manual Figure 1 — Figure 3 As shown, the finger monitoring assembly 1 includes a first rotating member 3 and a second rotating member 4 hinged to the first rotating member 3. The bottom of the first and second rotating members 4 are both provided with elastic sleeves 19. The finger monitoring assembly 1 is sleeved on the wearer's finger through the elastic sleeves 19, and the hinge point of the first rotating member 3 and the second rotating member 4 is located at the wearer's knuckle, so that the first rotating member 3 and the second rotating member 4 can keep pace with the wearer's knuckle movement. A first pressure touch switch 5 is provided between the first rotating member 3 and the second rotating member 4. When the first rotating member 3 and the second rotating member 4 are in the same horizontal straight line, the first pressure touch switch 5 is turned on and the contact signal is continuously output to the data integration module 6. By providing the first pressure touch switch 5 between the first rotating member 3 and the second rotating member 4, when the first rotating member 3 and the second rotating member 4 are in the same horizontal straight line (after the wearer's knuckle is straightened), the first pressure touch switch 5 is turned on and the opening time of the first pressure touch switch 5 is transmitted to the data integration module 6 of the limb monitoring assembly 2, and the straightening time of the wearer's knuckle is further judged according to the opening time of the first pressure touch switch 5. As for the number of finger monitoring components 1, at least three fingers are provided, and they are located on the thumb, the middle finger, and the index finger.

[0032] The limb monitoring component 2 is limited to the wrist or ankle of the wearer through the strap 18 set at the bottom, and is used to monitor the displacement frequency in the x, y, and z directions. Because when the initial symptoms of heat stroke appear, the limbs will twitch. When twitching occurs, the limbs are generally in a reciprocating motion in a single direction, so the displacement frequency of the limbs in the x, y, and z directions needs to be monitored.

[0033] The limb monitoring component 2 includes a shell 7, two first monitoring components 9, a second monitoring component and a data integration module 6; the first and second monitoring components monitor the frequency of limb movement displacement and upload the data to the data integration module 6, and the data integration module 6 is connected to the background terminal signal.

[0034] As the instruction manual Figure 4 — Figure 6 As shown, the first monitoring component 9 includes a rotating rod 10 arranged inside the shell 7, a vertical plate 11 rotatably connected to the rotating rod 10, and an angular displacement sensor 12 connected to the rotating rod 10; a bearing is provided between the rotating rod 10 and the vertical plate 11, and the rotating rod 10 is eccentrically provided with a rotating wheel 13, and the center of mass of the rotating wheel 13 is located below the rotating rod 10. Therefore, when the first monitoring component 9 moves along the circumference of the rotating wheel 13, the rotating wheel 13 rotates synchronously with the rotating rod 10, and the angular displacement sensor 12 records the position change of the rotating rod 10. One rotation is one time, and the number of times per unit time is the frequency.

[0035] It should be noted that: in the two usage scenarios of the device described at the beginning of the article, the amount of activity is different for monitoring outdoor workers and patients receiving treatment, so the monitoring sensitivity of the first monitoring component 9 needs to be adjusted according to the specific usage environment. This is because the data changes monitored by the angular displacement sensor 12 are mainly caused by the rotating wheel 13 driving the rotating rod 10. When other factors are the same, the main influencing factor of the rotation frequency of the two is the center of mass position of the rotating wheel 13. The larger the distance between the center of mass position of the rotating wheel 13 and the rotating rod 10, the faster the rotation frequency of the two, and the more sensitive the data monitored by the first monitoring component 9. Therefore, the center of mass of the rotating wheel 13 has different positions in different application environments.

[0036] As the instruction manual Figure 4 — Figure 6 As shown, the second monitoring component includes a sliding rod 14 arranged inside the housing 7, a pressing piece 15 slidably matched with the sliding rod 14, and a second pressure-touch switch 17 arranged below the pressing piece 15. When the wearer moves along the direction of the sliding rod 14, the pressing piece 15 is driven to slide along the sliding rod 14. At the same time, the pressing piece 15 falls under the gravity and acts on the second pressure-touch switch 17 below. At this time, the second pressure-touch switch 17 records the number of connections and transmits the data to the data integration module 6. The data integration module 6 records the activity frequency of the wearer in this direction within the cycle time. As for the monitoring sensitivity mentioned above, the sensitivity of the second monitoring component is inversely proportional to the sliding distance of the pressing piece 15, so the sliding distance of the pressing piece 15 is different when the second monitoring component is used in different environments.

[0037] The above only describes the structural principles of the first and second monitoring components. Because the wearer has displacement activity space in three directions of x, y, and z when moving, the number and monitoring directions of the first and second monitoring components are described in detail below:

[0038] There are many combinations of the number of the first and second monitoring components and the monitoring direction. First, it should be made clear that the setting direction of the first and second monitoring components is such that the setting direction of the rotating rod 10 of the first monitoring component 9 is perpendicular to the monitoring direction, so that the rotating wheel 13 is parallel to the monitoring direction, so that when moving along the monitoring direction, the rotating wheel 13 is driven to rotate along the rotating rod 10. The setting direction of the sliding rod 14 of the second monitoring component is consistent with the detection direction, so that when moving along the monitoring direction, the pressing piece 15 slides along the sliding rod 14, so that the pressing piece 15 presses the second pressure touch switch 17 when it falls back.

[0039] As for the number of the first and second monitoring components, the first monitoring component 9 is first analyzed. As for the monitoring principle of the first monitoring component 9, there are only two directions of power (x, y) to drive the rotating wheel 13 to rotate, and the z-axis direction cannot be monitored, because when setting, the x and y axis directions are perpendicular to the z axis, so the z-axis direction cannot be monitored. Therefore, the number of the first monitoring components 9 is only two at most, and can only be the x and / or y axis directions. For the second monitoring components, the number does not exceed three, because when the wearer has convulsions, he must be constantly reciprocating or shaking in a certain direction, so the number of second monitoring components is not limited. Therefore, the overall combination of the monitoring components has a variety of, but for the best implementation, the best combination is that the x and y axes are two first monitoring components 9, and the z axis is monitored by the second monitoring component. Because the first monitoring component 9 has a higher monitoring sensitivity and more monitoring directions than the second monitoring component, the above scheme is adopted for this.

[0040] The rotating wheel 13 rotates around the rotating rod 10 to perform simple harmonic motion, and the angular displacement sensor 12 determines the starting point of the rotating rod 10, and then the angular displacement sensor 12 records the changing position of the rotating rod 10, as shown in the accompanying drawings of the specification. Figure 7 As shown in the figure, it is a schematic diagram of the changing position of the rotating rod 10 in the three directions of x, y and z. By observing the line segment from the starting point 0 to point A in the figure, the shaking frequency of the 0-A segment in the x direction changes from slow to fast and then gradually decreases, the 0-A segment in the y direction is small in amplitude and fast in frequency, and the 0-A segment in the z direction is static. It can be judged that the wearer is moving along the x-y direction; in the A-B segment in the figure, the frequency of the A-B segment in the x direction gradually increases, the amplitude further decreases, and finally stops; the shaking frequency in the y direction becomes faster and then gradually stabilizes, the amplitude changes from small to maximum, the number of times in the z direction increases, and the time interval is longer; the B-C segment in the figure is the continuous stage. The judgment of the wearer's situation will be described below.

[0041] In order to help improve the overall monitoring accuracy of the device, the device also includes a temperature monitoring module, which contacts the wearer's skin surface through a thermistor. This module has little practical significance because the temperature of outdoor workers will be affected by the ambient temperature and exposure to the sun. For patients receiving treatment, they must be in a high fever state. However, in order to prevent workers in high temperature and high humidity environments from having high fever, a temperature monitoring module is set. For outdoor workers and patients using this device, other differences are: the power supply to the device and the data integration module 6 are different from the background terminal connection port. The above is what those skilled in the art can know, so it will not be described. The description of the structural principle of this device is complete. The following is the method of using the device, that is, how to monitor the wearer:

[0042] First, the monitoring principle is briefly described. In the early stage of heat stroke, fingers will become stiff and "chicken claw-like", accompanied by shaking or subtle twitching. Once symptoms appear, they are easily ignored. Therefore, the finger monitoring component 1 monitors the knuckle extension time, and the limb monitoring component 2 monitors the twitching frequency. As for the physiological structure of the human body, when the human body is relaxed or working, the fingers are mostly in a bent state, unless the human body is deliberately controlled to be in a fully extended state for a short time. Therefore, the finger monitoring component 1 is used to monitor the extension of the human body's knuckles. As for the specific monitoring process, when the first rotating member 3 and the second rotating member 4 are in the same horizontal straight line, the wearer's knuckles are extended, and the wearer's finger state is judged by recording the connection time of the first pressure touch switch 5. For outdoor workers, the situation is more complicated, so at least three first pressure touch switches 5 of the finger monitoring components 1 are pressed and touched continuously for 25-30 seconds at the same time, it is considered that the wearer has chicken claw hands, and it needs to be sent to the background terminal through the data integration module 6 for alarm; for patients receiving treatment, it indicates that the patient has received treatment, and the monitoring is to monitor the patient's worsening condition and the need to re-use the medicine after the expiration of the medicine. This situation is relatively simple, so at least three pressure touch switches of the finger monitoring components 1 are pressed and touched continuously for 15-20 seconds at the same time, and then sent to the background terminal through the data integration module 6 for alarm.

[0043] For the monitoring process of the limb monitoring component 2, the shaking frequency and time in the three directions of x, y, and z are monitored by the first and second monitoring components. For the same outdoor workers, the situation is more complicated, so the monitoring component in any monitoring direction continues to shake for 50-60 seconds, and the frequency is more than 0.5 times per second; for patients receiving treatment, the monitoring component in any direction continues to shake for 20-30 seconds, and the frequency is more than 1 time per second. Because for outdoor workers, the long continuous shaking time is due to frequent activities to avoid misjudgment during activities. As for the shaking frequency, it is slower than that of patients receiving treatment, because the early stage of heat stroke in outdoor workers cannot be monitored, and the twitching frequency of patients receiving treatment is fast, so they are distinguished according to their characteristics.

[0044] For the device as a whole, because of the above-mentioned alarm conditions, the human body rarely encounters the above-mentioned situation during normal activities. Therefore, once the finger monitoring component 1 and / or limb monitoring component 2 of the wearer alarms, it is necessary to immediately send an alarm to the background terminal through the data integration module 6, check the wearer's condition in time, and provide timely treatment to the wearer.

[0045] In summary, the device can monitor whether the wearer in different environments has heat stroke, and judge the wearer's specific condition based on the trajectory of limb movement and the state of finger joints, so as to timely detect the wearer's physical condition in the early stage of heat stroke. For patients receiving treatment, it can timely detect whether the patient's condition is getting worse or the efficacy of the medicine is weakened, and can timely check the patient's specific condition and give the patient medication in time.
