Description

Technical Field

[0001] The present invention relates to the technical field of warning devices, and more specifically to an epilepsy seizure warning device. Background Art

[0002] Epilepsy is a chronic brain disease, commonly known as "falling sickness" among the people. When a patient has an epileptic seizure, symptoms such as convulsions, foaming at the mouth, and loss of consciousness may occur. In severe cases, the patient may even suffocate and endanger life due to the blockage of the respiratory tract by vomited foreign objects.

[0003] In order to reduce the harm caused by epileptic seizures, it is necessary to take timely rescue measures when a patient has a seizure. However, when an epileptic patient is not having a seizure, they are no different from ordinary people, and seizures occur without warning. In the prior art, the patient's brain waves, heart rate, etc. are generally monitored to determine whether the patient has a seizure. For example, a device for dynamically warning of epileptic seizures with the publication number CN106491126B in the prior art.

[0004] However, when the patient's heart rate and brain waves have already shown abnormalities, it means that the patient has already had a seizure or is about to have a seizure. At this time, when a warning is issued, the reaction time left for others is already very short. Moreover, the heart rate and brain waves are also affected by the patient's emotions and the surrounding environment, and false triggering is likely to occur.

[0005] Therefore, it can be said that the epilepsy warning in the prior art not only has room for improvement in accuracy, but also has poor warning prospectiveness, making it difficult to predict epileptic seizures earlier, and thus unable to give more preparation time to people around the patient, resulting in a poor warning effect. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an epilepsy seizure warning device, which determines whether a patient has encountered factors that induce epilepsy through a first test component, and then evaluates the probability of the patient having a seizure, improving the prospectiveness of the warning.

[0007] To achieve the above object, the present invention provides the following technical solution: an epilepsy seizure warning device, including a nursing bed, a protective fence is fixedly provided at the top of the nursing bed, the protective fence surrounds three sides of the nursing bed, leaving one side open, and a first test component is provided on the protective fence;

[0008] The first test component includes a test panel installed on the nursing bed by bolts. A plurality of toggle switches, a plurality of information nameplates, and a plurality of indicator light strips are provided on the front side of the test panel. The toggle switches, information nameplates, and indicator light strips correspond one by one. The indicator light strip is provided above the corresponding toggle switch, and the information nameplate is provided below the corresponding toggle switch.

[0009] There are at least seven lever switches, information nameplates, and indicator light strips. When the lever switch is turned up, the corresponding indicator light strip will be lit. When the indicator light strip is turned down, the corresponding lever switch will not be lit. The factors inducing epilepsy are marked on the information nameplate from left to right, including but not limited to drinking alcohol, taking medicine, staying up late and insomnia, dizziness and fatigue, stimulation and fright, anger and anxiety, and sudden temperature change. These seven factors correspond to seven lever switches. According to the information on the information nameplate, if the corresponding situation occurs, the corresponding lever switch is turned up, and vice versa.

[0010] Further, a controller and a networking module are fixedly provided at the rear side of the nursing bed. The controller is wirelessly connected to a mobile terminal through the networking module. The mobile terminal is a computer or a mobile phone of the patient's family member. The lever switch is provided at the input end of the controller, and the indicator light strip is provided at the output end of the controller. An electronic alarm clock is detachably provided on the guardrail, and the electronic alarm clock is provided at the output end of the controller;

The heart rate detection module and the body temperature detection module are provided at the input end of the controller. A power cord for supplying power to electrical components is provided at the rear side of the nursing bed.

[0012] Further, an inflatable mattress is detachably provided at the top end of the nursing bed. The inflatable mattress has no elasticity. Therefore, after it is filled with air, even if the air pressure continues to increase, the volume of the inflatable mattress will no longer change. A rubber pillow is provided at the top end of the inflatable mattress. The middle part of the rubber pillow bulges upward, and the connection between the horizontal part and the bulging part presents an arc-shaped slope.

[0013] Further, a pneumatic component is provided at the rear side of the nursing bed. The pneumatic component includes a mounting vertical plate fixedly provided at the bottom end of the rear side of the nursing bed. A detachable pneumatic cylinder is provided at the rear side of the mounting vertical plate. The inflatable mattress is connected to the inside of the pneumatic cylinder through a connecting pipe.

[0014] Further, a closed cover is detachably provided at one end of the pneumatic cylinder. A gas guide pipe with a valve is fixedly provided at the end of the closed cover away from the pneumatic cylinder. Inflation or deflation is carried out through the gas guide pipe.

The end cap is provided with a vent hole penetrating the end cap. When the moving plug moves, the size of the space between the moving plug and the end cap will change, resulting in a change in air pressure. Air can then enter and exit this space through the vent hole to balance the air pressure and prevent the movement of the moving plug from being blocked due to poor air circulation.

[0017] Further, a vibration sensor is fixedly provided on the side of the moving plug away from the closed cover. The vibration sensor is arranged at the input end of the controller. The outer end of the air cylinder is fixedly provided with an electronic timing counter, and the electronic timing counter is arranged at the connection end of the controller.

[0018] Technical effects and advantages of the present invention:

[0019] 1. The present invention determines whether a patient has encountered factors inducing epilepsy through the first test component, and then evaluates the probability of the patient's onset, enabling earlier warning of the patient's onset, improving the forward-looking nature of the warning, giving the patient's family more preparation time, and thus improving the effect of the warning.

[0020] 2. By judging the patient's sleep condition based on the patient's body movement at night, it is further determined whether the patient is likely to have an onset or has already had an onset, so as to take timely measures, thereby providing timely and effective warning at night when the patient is alone, and further improving the effect of the warning.

Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Refer to the attached drawings of the specification Figures 1-8 The present invention provides an epilepsy seizure warning device, including a nursing bed 1. A protective railing 101 is fixedly arranged at the top of the nursing bed 1. The protective railing 101 surrounds the nursing bed 1 on three sides, leaving one side open. Patients get on and off the nursing bed 1 through the open side. The first test component 5 is arranged on the protective railing 101;

[0033] An inflatable mattress 2 is detachably arranged at the top of the nursing bed 1. The inflatable mattress 2 has no elasticity. Therefore, after it is filled with air, even if the air pressure continues to increase, the volume of the inflatable mattress 2 will no longer change. A rubber pillow 3 is arranged at the top of the inflatable mattress 2. The middle part of the rubber pillow 3 bulges upward, and the connection between the horizontal part and the bulging part presents an arc-shaped slope.

[0034] Epileptic patients rest on the nursing bed 1 every night. The inflated inflatable mattress 2 plays a buffering role between the patient's body and the nursing bed 1, improving the comfort of the patient during rest. The protective railing 101 surrounding the nursing bed 1 on all sides can prevent the patient from rolling off the top of the nursing bed 1 during daily rest;

[0035] Meanwhile, when the patient sleeps, the head is placed on the top of the rubber headrest 3. The protrusions on the rubber headrest 3 divide the space at the top of the rubber headrest 3 into two parts, and the connection between the horizontal part and the protruding part presents an arc-shaped slope. This special shape is not conducive to the patient sleeping in a flat position because the slope cannot stably support the head in a flat position, and the flat head is extremely likely to deflect to the side away from the protrusion. Only by adopting a lateral position, making the side of the head contact the top of the rubber headrest 3, can the arc-shaped slope fit the back of the head, so that the rubber headrest 3 can stably support the patient's head. Therefore, epileptic patients are forced to sleep in a lateral position with their back to the protruding part on either side of the protrusion according to their own habits. In this way, once an epileptic seizure occurs, vomit will be more likely to be discharged from the mouth, avoiding blocking the patient's airway and causing asphyxia, and improving the safety of epileptic patients' sleep.

[0036] Before going to bed and after waking up every day, evaluate the risk of epileptic seizures according to the patient's own situation, such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 As shown, the first test component 5 includes a test panel 501 installed on the nursing bed 1 by bolts. A plurality of toggle switches 502, a plurality of information nameplates 503, and a plurality of indicator light strips 504 are provided on the front side of the test panel 501. The toggle switches 502, the information nameplates 503, and the indicator light strips 504 are in one-to-one correspondence. The indicator light strip 504 is provided above the corresponding toggle switch 502, and the information nameplate 503 is provided below the corresponding toggle switch 502.

[0037] When the toggle switch 502 is turned up, the corresponding indicator light strip 504 will be lit. When the indicator light strip 504 is turned down, the corresponding toggle switch 502 will not be lit. Seven factors that induce epilepsy are marked on the seven information nameplates 503 from left to right, which are drinking alcohol, taking medicine, staying up late and insomnia, dizziness and fatigue, stimulation and fright, anger and anxiety, and sudden temperature change respectively. These seven factors correspond to the seven toggle switches 502. According to the information on the information nameplate 503, if the corresponding situation occurs, the corresponding toggle switch 502 is turned up, otherwise it is turned down. The number of toggle switches 502 is not limited to seven. Other factors that induce epilepsy can be added, and the corresponding toggle switches 502 can be increased accordingly, but it is necessary to ensure that the numbers of the toggle switches 502, the information nameplates 503, and the indicator light strips 504 change synchronously, and the numbers of the three always remain the same.

[0038] The above seven factors are all likely to induce epileptic seizures in patients. According to their own situations, patients answer yes or no by sequentially toggling these seven lever switches 502. Answering yes will cause the indicator strip 504 corresponding to the corresponding lever switch 502 to be lit, and answering no will not light the indicator strip 504. Therefore, the more indicator strips 504 are lit, the more factors inducing epilepsy the patient encounters, and the greater the probability of the patient having a seizure. Therefore, according to the number of lit indicator strips 504, the seizure probability of the patient is divided into levels 1-7.

[0039] A controller 8 and a networking module 9 are fixedly provided at the rear side of the nursing bed 1. The controller 8 is wirelessly connected to a mobile terminal through the networking module 9. The networking module 9 can be a network connection module of model EBT3001, and the controller 8 can be a controller of model TECNA DC200 / TE503. The mobile terminal is a computer or mobile phone of the patient's family member. The lever switch 502 is arranged at the input end of the controller 8, and the indicator strip 504 is arranged at the output end of the controller 8. An electronic alarm clock 4 is detachably provided on the guardrail 101, and the electronic alarm clock 4 is arranged at the output end of the controller 8;

[0040] Epileptic patients need to ensure good sleep habits. Therefore, the daily sleep time and wake-up time are set through the electronic alarm clock 4. After the evening sleep time and the morning wake-up time are reached, the electronic alarm clock 4 will sound a reminder tone to remind the patient. The sound of the reminder tone gradually increases from small to avoid scaring the patient. The reminder tone will not stop automatically and will only stop after a risk assessment is made through the first test component 5. Therefore, it is necessary for the patient to objectively toggle each lever switch 502 one by one according to their actual situation. After all the lever switches 502 are toggled, the reminder tone of the electronic alarm clock 4 will stop, so as to forcibly assess the seizure risk of the patient.

[0041] After the seizure probability of the patient is evaluated by the first test component 5, the evaluation result is processed by the controller 8 and then transmitted to the mobile phone or computer of the patient's family member through the networking module 9. The patient's family member can then understand the seizure probability level of the patient. The higher the level, the greater the probability of the patient having an epileptic seizure. The patient's family member should be more prepared for the patient's seizure. By calming the patient's emotions or taking relevant medications under the guidance of a doctor, it is beneficial to avoid seizures. At the same time, it is also necessary to make preparations for the treatment of the patient once a seizure occurs. In this way, it can be judged whether the patient has encountered factors inducing epilepsy, and then the seizure probability of the patient can be evaluated, which can warn the patient's seizure earlier, improve the foresight of the warning, give the patient's family member more preparation time, and thus improve the warning effect.

[0042] It is also possible to evaluate the seizure probability of the patient through the patient's physical indicators, such as Figure 5 、 Figure 8As shown, a second test component 6 is detachably provided on the guardrail 101. The second test component 6 includes a test ring 601. A heart rate detection module 602 and a body temperature detection module 603 are fixedly provided on the inner wall of the test ring 601. The heart rate detection module 602 and the body temperature detection module 603 are provided at the input end of a controller 8. A power cord for supplying power to electrical components is provided at the rear side of the nursing bed 1. The heart rate detection module 602 is a photoelectric heart rate sensor, and the selectable model is MAX30102. The light emitted by it penetrates the skin, and the electrical signal received and converted by the photosensitive element reflects the change in heart rate. The body temperature detection module 603 can select a temperature sensor with the model NST112X. The body temperature and heart rate detection technologies are both applied on smart watches and smart bracelets, which belong to mature existing technologies, so no more details will be given.

[0043] While the patient is being evaluated using the first test component 5, the patient can insert the hand into the test ring 601 so that the test ring 601 is sleeved on the patient's wrist. The heart rate detection module 602 and the body temperature detection module 603 can then detect the patient's body temperature and heart rate, and the physical condition of the patient can be reflected through the detection results. Whether epilepsy will occur can be warned by whether the body temperature and heart rate are abnormal. The function of detecting brain waves or blood oxygen can also be added on this basis, and no more details will be given here. In this way, the physical indicators are detected on the premise of combining the actual situations such as the patient's mood, mentality, and the environment, and then the risk of epilepsy onset is evaluated, avoiding the phenomenon of false touch or inaccurate detection that may be caused by the actual situations such as mood, mentality, and the environment, and improving the accuracy of detection and warning.

[0044] Epileptic patients need extra care from people around them such as family members and friends. It is easier to take care of epileptic patients during the day, and even if they have an attack, it is easier to get treatment. Once the patient sleeps alone at night and has an attack during sleep, it is quiet at night and it is not easy to get treatment. To avoid this problem, as Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 As shown, a pneumatic component 7 is provided at the rear side of the nursing bed 1. The pneumatic component 7 includes a mounting vertical plate 709 fixedly provided at the bottom end of the rear side of the nursing bed 1. A detachable pneumatic cylinder 701 is provided at the rear side of the mounting vertical plate 709. The inflatable mattress 2 is connected to the inside of the pneumatic cylinder 701 through a connecting pipe.

[0045] One end of the air cylinder 701 is detachably provided with a closed cover 702. A gas guide pipe with a valve is fixedly provided at the end of the closed cover 702 away from the air cylinder 701. Inflation or deflation is carried out through the gas guide pipe. A pressure sensor 708 is fixedly provided on the inner wall of the closed cover 702. The pressure sensor 708 is arranged at the input end of the controller 8. The top end of the connecting pipe is fixedly connected to the inflatable mattress 2, and the bottom end is detachably connected to the top end of the closed cover 702. The model of the pressure sensor 708 that can be adopted is the DSH700B pressure sensor. By filling the closed cover 702 with air through the gas guide pipe, it can enter the inflatable mattress 2 through the connecting pipe, filling the inside of the inflatable mattress 2 with air. The pressure sensor 708 can then sense the pressure change during the inflation process to determine whether the inside of the inflatable mattress 2 is full of air.

[0046] When the patient is resting at night on the inflatable mattress 2, when the patient has a seizure, the convulsions of the body will cause the inflatable mattress 2 to vibrate, and the air pressure inside it will continuously change with the vibration. The air pressure inside the air cylinder 701 communicated with the inflatable mattress 2 will also continuously change.

[0047] A moving plug 706 is arranged inside the air cylinder 701. A sealing gasket in contact with the inner wall of the air cylinder 701 is fixedly provided at the outer end of the moving plug 706. A spring 705 is fixedly provided on the side of the moving plug 706 away from the closed cover 702. When the inflatable mattress 2 is full of air, the spring 705 will be in a compressed state;

[0048] When the air pressure inside the air cylinder 701 continuously changes, the air pressure will drive the movement of the moving plug 706. When the air pressure increases, the moving plug 706 moves away from the closed cover 702 and compresses the spring 705. On the contrary, the moving plug 706 approaches the closed cover 702 and the elastic force of the spring 705 is released. Therefore, the vibration of the inflatable mattress 2 will cause the moving plug 706 to move back and forth inside the air cylinder 701.

[0049] A detachable end cover 703 is provided at the end of the air cylinder 701 away from the closed cover 702. The end of the spring 705 away from the closed cover 702 is fixedly connected to the end cover 703. A ventilation hole 704 penetrating the end cover 703 is provided on the end cover 703. When the moving plug 706 moves, the size of the space between the moving plug 706 and the end cover 703 will change, thereby causing a change in air pressure. Air can then enter and exit this space through the ventilation hole 704 to balance the air pressure and prevent the movement of the moving plug 706 from being blocked due to poor air circulation.

[0050] On the side of the movable plug 706 away from the closed cover 702, a vibration sensor 707 is fixedly provided. The vibration sensor 707 can be a vibration sensor with the model SSF-VIB-Z300. The vibration sensor 707 is arranged at the input end of the controller 8. At the outer end of the air cylinder 701, an electronic timing counter 10 is fixedly provided. The electronic timing counter 10 is arranged at the connection end of the controller 8. The electronic timing counter 10 can be a GX7-P42E electronic timing counter.

[0051] The reciprocating motion of the movable plug 706 will cause the vibration sensor 707 to sense the vibration of the movable plug 706. Each time the vibration sensor 707 vibrates, the electronic timing counter 10 will count once. However, the electronic timing counter 10 only records the vibrations of the movable plug 706 with an amplitude greater than 0.5 cm to avoid false touches. According to the count of the electronic timing counter 10, when the vibration frequency of the vibration sensor 707 reaches 5 - 20 times per minute, it indicates that the patient is tossing and turning, having difficulty falling asleep, or is anxious and has poor sleep quality at this time. The patient is prone to frequently adjusting the sleeping position, which will cause the vibration of the inflatable mattress 2, and further cause the vibration sensor 707 to sense the vibration of the movable plug 706. According to medical knowledge, the patient's anxiety and insomnia at night are signs of an impending illness. This situation indicates that the probability of the patient getting sick has increased significantly. At this time, the vibration data will be transmitted to the mobile terminal through the controller 8 and the networking module 9, enabling the patient's family members to notice the patient's sleep situation when alone, so as to issue a warning and attract attention.

[0052] When the vibration frequency of the vibration sensor 707 is greater than 20 times per minute, it indicates that the patient's body vibrates frequently, and it is very likely that the patient is having convulsions caused by epilepsy. At this time, the controller 8 and the networking module 9 will directly send an alarm message to the mobile terminal so that the patient's family members can rush to the patient's side in time to check the situation. If the patient is indeed sick, timely treatment will be carried out. This early warning method can judge the patient's sleep situation through the patient's body activities at night, and then judge whether the patient is likely to get sick or has already gotten sick, so as to take timely measures, thereby providing timely and effective early warning at night when the patient is alone and further improving the effect of early warning.

[0053] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
