Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a protective device and method for patients with epileptic seizures used in neurological nursing. Background Technology

[0002] Epilepsy is an acute, recurrent, paroxysmal brain dysfunction caused by excessive discharge of neurons in the brain, manifesting as disturbances in consciousness, motor function, autonomic nervous system, and mental state. Epileptic seizures are a common neurological emergency, occurring at any age, but with the highest incidence in children and adolescents. Epileptic seizures, especially grand mal seizures, are sudden and require immediate and effective treatment; failure to act promptly or proper management can often be life-threatening.

[0003] Existing technology discloses some patent documents related to protective devices for patients with epileptic seizures. Chinese patent application number 202110453370.0 discloses a patent for a safe hospital bed for epileptic patients, including a main body. A pair of protective plates are rotatably connected to the main body, and the main body is provided with rotating grooves that cooperate with the protective plates. Two pairs of rotating constraint blocks are rotatably connected inside the main body. Multiple massage blocks are provided on the main body. A pair of second constraint belts are provided on the main body. A fixing block is fixed to the main body. A pair of first fixing clips are slidably connected to the fixing block. A first support bracket that cooperates with the first fixing clips is slidably connected inside the fixing block. A support frame is provided below the main body, and a cooperating first lifting mechanism is provided between the main body and the support frame.

[0004] Existing protective devices are inconvenient to notify caregivers in a timely manner when a patient has a seizure while unattended, making it easy for the patient to have convulsions in bed. On the one hand, vomit can easily block the trachea and cause suffocation; on the other hand, the patient is also prone to falling off the bed and getting injured. Therefore, this paper proposes a protective device and method for patients with epileptic seizures in neurology nursing. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device and method for patients with epileptic seizures in neurology care, which can not only prevent patients from falling or being hit during a seizure, but also promptly notify caregivers to prepare for protection.

[0006] To achieve the above objectives, the present invention provides a protective device for patients with epileptic seizures in neurological nursing, including a bed, a headboard at one end of the bed, an oral protection component on the headboard, lifting and protective components on both sides of the bed, a unilateral height-increasing component inside the bed, and a monitoring and early warning system.

[0007] Preferably, the oral protection component includes an oral protector placed in a storage slot on one side of the headboard.

[0008] Preferably, the oral protector consists of two symmetrical arc-shaped clamps, with a soft silicone pad on the inner side of the arc-shaped clamps. A drug release chamber is provided between the silicone pad and the arc-shaped clamps, and a certain dose of anti-epileptic drug is provided in the drug release chamber.

[0009] Preferably, the lifting and protective assembly includes a protective railing, the surface of which is covered with a soft rubber pad.

[0010] Preferably, a driven rack is fixedly connected to the middle part of the inner side of the protective railing. The driven rack is made of 20CrMnTi carburized and quenched material, with a surface hardness of 58-62HRC and a carburized layer depth of 0.8-1.2mm. A positioning hole is machined every 50mm along the length direction on the side of the driven rack, and the diameter of the positioning hole is 6mm.

[0011] Preferably, a drive gear meshes with one side of the driven rack, the drive gear is fixed in the gearbox via a drive gear shaft, a drive motor is fixed on one side of the gearbox, the drive motor is a DC geared motor, fixed to the bottom of the bed via a flange, the output shaft of the drive motor is rigidly fixed to the drive gear shaft via a key connection, and an electromagnetic lock is installed on the side of the gearbox, the electromagnetic lock tongue corresponding to the positioning hole on the side of the driven rack.

[0012] Preferably, the upper and lower ends of the protective railing are respectively fixed with limit blocks, and a metal sensing plate is installed at the position of the limit block corresponding to the bed body. The metal sensing plate cooperates with the Hall sensor of the drive motor controller.

[0013] Preferably, the single-sided height-increasing component includes an upper bed board and a lower bed board, which are connected by a pivot. An air cushion is provided on the side of the upper bed board away from the pivot between the upper bed board and the lower bed board, and the air cushion is fixedly installed on the lower bed board by a flexible buffer strip.

[0014] A silent air pump is fixedly installed at the bottom of the bed. The outlet end of the silent air pump is equipped with an electromagnetic reversing valve. The silent air pump is connected to the air cushion through a polyurethane air pipe with a diameter of 8mm.

[0015] Preferably, the monitoring and early warning system consists of multiple sensors and an intelligent controller. The sensors include a pressure sensor installed on the surface of the bed to monitor the patient's position and body movement; a pulse sensor worn on the patient's wrist to monitor the patient's pulse in real time; and a respiratory sensor installed on the patient's chest to monitor the patient's respiratory rate and depth. The intelligent controller is connected to a handheld terminal of medical staff via a wireless communication module.

[0016] The present invention also provides a protection method for a patient protection device for epileptic seizures used in neurological nursing, comprising the following steps:

[0017] S1. Real-time monitoring and early warning: During the use of protective equipment, the various sensors of the monitoring and early warning system work continuously to collect the patient's physiological data and body movement data in real time.

[0018] S2. Seizure Protection: Once a patient begins a seizure, the lifting and protective components and the unilateral heightening components are quickly activated. Throughout the seizure, the monitoring and early warning system continuously monitors the patient's physiological data and body movement, and feeds the data back to the intelligent controller in real time.

[0019] S3. Post-seizure management: After the patient's epileptic seizure ends, the monitoring and early warning system detects that the patient's physiological indicators gradually return to normal and the body movement tends to be stable. The intelligent controller will issue instructions to control the various components of the protection equipment to return to their initial state.

[0020] Therefore, the present invention employs the above-mentioned protective device and method for patients with epileptic seizures in neurological nursing, and the technical effects are as follows:

[0021] The monitoring and early warning system imbues the protective equipment with intelligent features. It can detect signs of an impending seizure in advance, allowing for proactive protective measures and significantly improving the timeliness and effectiveness of protection. Furthermore, the system can dynamically adjust various components of the protective equipment based on real-time data during a seizure, ensuring optimal protection at all times.

[0022] The protective equipment is easy to operate, with each component automatically controlled by an intelligent controller. Medical staff only need to perform simple operations during routine maintenance and patient use. In emergencies, the equipment can respond automatically, eliminating the need for manual operation by medical staff, saving valuable time and improving treatment efficiency.

[0023] The protection method of this invention covers three stages: monitoring and early warning, seizure protection, and post-seizure management, forming a complete closed-loop protection process. It not only provides effective protection during a seizure but also provides early warning before a seizure and stores and analyzes relevant data after a seizure, offering strong support for doctors' diagnosis and treatment, and helping to improve the overall care level for epilepsy patients.

[0034] Example 1

[0035] like Figure 1 , Figure 3As shown, the present invention provides a protective device for patients with epileptic seizures in neurological nursing, including a bed body 1, a headboard 2 at one end of the bed body 1, an oral protection component on the headboard 2, the oral protection component including an oral protector, the oral protector being placed in a storage slot 4 on one side of the headboard 2.

[0036] like Figure 4 As shown, the oral protector consists of two symmetrical arc-shaped plates 16. In use, the two arc-shaped plates 16 are joined together. A soft silicone pad 17 is located on the inner side of each arc-shaped plate 16. When a patient has a seizure, medical staff can place the oral protector in the patient's mouth to open the patient's upper and lower teeth, preventing tongue biting and improving patient comfort. Simultaneously, a drug-releasing chamber 18 is located between the silicone pad 17 and the arc-shaped plates 16, containing a specific dose of antiepileptic drug. When the patient bites down on the oral protector, the drug-releasing device is triggered, slowly releasing a specific dose of antiepileptic drug, such as diazepam. This drug is absorbed through the oral mucosa, quickly exerting its effect and relieving seizure symptoms.

[0037] Simultaneously, two sets of adjustable-length limb restraint straps are installed on each side edge of the bed frame 1. The straps are made of high-strength Velcro material for easy and quick fastening and loosening. Each strap is connected to an electric tightener, which is controlled by a controller. When a seizure is detected, the controller automatically adjusts the tightness of the straps based on the patient's limb movements. This effectively restrains the limbs, preventing uncontrolled swinging and potential collision injuries, while avoiding excessive tightness that could impair blood circulation. Soft padding is also provided on the inside of the straps to enhance patient comfort.

[0038] The bed 1 is equipped with lifting and protective components on both sides. The lifting and protective components include a guardrail 3. The surface of the guardrail 3 is covered with a soft rubber pad. When the patient has an attack, the guardrail 3 is raised to prevent the patient from falling or being injured by collision.

[0039] A driven rack 7 is fixedly connected to the middle part of the inner side of the guardrail 3. The driven rack 7 is made of 20CrMnTi carburized and quenched material with a surface hardness of 60HRC and a carburized layer depth of 1.2mm. A positioning hole 8 is machined every 50mm along the length of the side of the driven rack 7. The diameter of the positioning hole 8 is 6mm.

[0040] like Figure 5As shown, a drive gear 20 meshes with one side of the driven rack 7. The drive gear 20 is fixed inside the gearbox 15 via a drive gear shaft 19. A drive motor 14 is fixedly mounted on one side of the gearbox 15. The drive motor 14 is a DC geared motor, fixed to the bottom of the bed 1 via a flange. The output shaft of the drive motor 14 is rigidly fixed to the drive gear shaft 19 via a key connection. An electromagnetic lock 22 is installed on the side of the gearbox 15, and the locking tongue of the electromagnetic lock 22 corresponds to the positioning hole 8 on the side of the driven rack 7.

[0041] Meanwhile, limit plates 21 are fixedly provided on both sides of the gearbox 15. Rollers 23 are fixedly provided on the inner wall of the limit plate 21 and between it and the outer wall of the driven rack 7. The rollers 23 can limit the driven rack 7, so that the driven rack 7 and the driving gear 20 are tightly meshed, which can effectively ensure the smooth operation of the lifting assembly.

[0042] When the protective barrier 3 reaches the set height, the electromagnetic lock controller outputs a 24V DC voltage to drive the bolt of the electromagnetic lock 22 to pop out and insert into the positioning hole 8 to achieve mechanical locking, with a response time of ≤0.3 seconds. When unlocking, the voltage is cut off, and the bolt of the electromagnetic lock 22 retracts under the action of the return spring.

[0043] The drive motor 14 and gearbox 15 enable the drive gear 20 to push the driven rack 7 to move, thereby realizing the up and down movement of the guardrail 3. Lifting ports 5 are provided on both sides of the bed body 1, and the guardrail 3 moves up and down through the lifting ports 5.

[0044] Limiting blocks 6 are fixed at the upper and lower ends of the guardrail 3, and metal sensing plates are installed at the positions of the limiting blocks 6 corresponding to the bed body 1. The metal sensing plates cooperate with the Hall sensor of the drive motor controller to achieve automatic stopping at the end of the lifting stroke.

[0045] Meanwhile, two sets of guide sliders are welded to the inner side of the protective railing 3. The inner holes of the guide sliders slide in engagement with the guide shaft fixed on the bed 1. Dust covers made of polyurethane are installed at both ends of the guide sliders to prevent dust from entering the mating surfaces. The guide shaft is arranged parallel to the driven rack 7, with a straightness error ≤0.1mm / m. A one-way overrunning clutch is connected in series on the drive gear shaft 19. When the drive motor 14 is powered off or malfunctions, the clutch automatically locks the drive gear shaft 19 to prevent the protective railing 3 from falling due to its own weight.

[0046] The protective device is also equipped with a monitoring and early warning system, which consists of multiple sensors and an intelligent controller. The sensors include a pressure sensor installed on the surface of the bed 1 to monitor the patient's position and body movement; a pulse sensor worn on the patient's wrist to monitor the patient's pulse in real time; and a respiratory sensor installed on the patient's chest to monitor the patient's respiratory rate and depth. The intelligent controller is connected to the handheld terminal of medical staff via a wireless communication module.

[0047] Multiple sensors transmit collected data to the intelligent controller in real time, which analyzes and processes the data using built-in algorithms. When the intelligent controller determines that a patient is about to have an epileptic seizure, it will issue an early warning signal to remind medical staff to prepare protective measures. At the same time, the warning signal will also trigger various components of the protective equipment, putting them into working mode in advance to ensure timely and effective protection at the moment of the seizure.

[0048] The bed frame 1 is equipped with a single-sided height-increasing component, which includes an upper bed board 10 and a lower bed board 12. The upper bed board 10 and the lower bed board 12 are connected by a pivot 11. At the same time, an air cushion 13 is provided on the side of the upper bed board 10 and the lower bed board 12 away from the pivot 11. The air cushion 13 is fixedly installed on the lower bed board 12 by a flexible buffer strip.

[0049] A silent air pump 9 is fixedly installed at the bottom of the bed body 1. The outlet end of the silent air pump 9 is equipped with an electromagnetic reversing valve. The silent air pump 9 is connected to the air cushion 13 through a polyurethane air tube with a diameter of 8mm. The response time of the silent air pump 9 is less than 2 seconds, and it can complete the maximum stroke inflation within 10 seconds.

[0050] When a seizure is detected, the intelligent controller activates the silent air pump 9, inflating the air cushion 13. This causes one side of the upper bed board 10 to be lifted by the pivot 11 and the air cushion 13, allowing the patient to lie on their side and preventing vomit from blocking the airway. Figure 2 As shown.

[0051] During inflation, the intelligent controller synchronously instructs the corresponding side of the protective railing 3 to rise to the highest position and appropriately tightens the upper body fixation strap of the limb fixation device (increasing restraint while maintaining comfort) to ensure the patient's position is stable.

[0052] Once the patient's condition stabilizes, the intelligent controller receives a reset signal (manual / automatic), the electromagnetic reversing valve switches to the deflation path, the air cushion 13 deflates within 30 seconds, the bed surface returns to a horizontal state, and the protective railing 3 and the fixing straps return to their normal mode.

[0053] The process of using the protection equipment:

[0054] 1. After the patient is admitted to the ward, medical staff will push the protective equipment to the patient's bedside and ensure that the bed is stable. A pulse sensor will be attached to the patient's wrist, a respiratory sensor will be installed on the chest, and a pressure sensor will be placed on the surface of the bed.

[0055] 2. During the patient's rest period, the monitoring and early warning system begins to operate, continuously collecting the patient's physiological and physical movement data, which are then analyzed and processed by the intelligent controller. When the intelligent controller determines that the patient is about to have an epileptic seizure, it issues an early warning signal, and medical staff, upon receiving the warning information, quickly rush to the ward.

[0056] 3. During a seizure, the protective device automatically activates. Medical staff quickly insert the oral protector into the patient's mouth; the limb immobilization device adjusts the tightness of the straps according to the patient's limb movements. Throughout the seizure, the monitoring and early warning system continuously monitors patient data, and the intelligent controller dynamically adjusts the protective device based on the data.

[0057] 4. After the patient's seizure ends, the protective equipment returns to its initial state under the control of the intelligent controller. Medical staff examine the patient to confirm their condition. Simultaneously, the intelligent controller uploads the data from this seizure to the hospital's information management system.

[0058] The present invention also provides a protection method for a patient protection device for epileptic seizures used in neurological nursing, comprising the following steps:

[0059] S1. Real-time monitoring and early warning: During the use of protective equipment, the various sensors of the monitoring and early warning system work continuously to collect the patient's physiological data and body movement data in real time.

[0060] The intelligent controller analyzes this data in real time. When it detects abnormal fluctuations in the patient's physiological indicators such as pulse and respiratory rate, and the patient's body movements are consistent with those before an epileptic seizure, it determines that the patient is about to have a seizure. At this time, the intelligent controller immediately issues an early warning signal. On the one hand, it sends the warning information to the medical staff's handheld terminal, such as a mobile phone or tablet, via the wireless communication module, reminding the medical staff to arrive at the scene as soon as possible. On the other hand, it triggers the various actuators of the protection equipment, putting them into a ready state.

[0061] S2. Seizure Protection: Once a seizure begins, the lifting and lowering protective components and the unilateral elevation component activate rapidly. Medical staff quickly place the oral protector in the patient's mouth to open the upper and lower teeth, while the drug-release device releases anti-epileptic medication. The electric tightening device of the limb immobilization device automatically adjusts the tightness of the fixation straps according to the patient's limb movements, securing the limbs. Throughout the seizure, the monitoring and early warning system continuously monitors the patient's physiological data and body movements, feeding the data back to the intelligent controller in real time. The intelligent controller dynamically adjusts various components of the protective equipment based on this data to ensure optimal protection. For example, if the patient's limbs are found to be struggling excessively, the intelligent controller will appropriately increase the tightening force of the fixation straps.

[0062] S3. Post-seizure management: After the patient's epileptic seizure ends, the monitoring and early warning system detects that the patient's physiological indicators gradually return to normal and the body movement tends to be stable. The intelligent controller will issue instructions to control the various components of the protection equipment to return to their initial state.

[0063] Meanwhile, the intelligent controller stores and analyzes relevant data about the patient's attack, such as the time of attack, duration of attack, and changes in physiological indicators during the attack. This data is then transmitted to the hospital's information management system via a wireless communication module, providing a reference for doctors' subsequent diagnosis and treatment. Medical staff arrived at the scene to conduct further examinations and provide care to the patient, ensuring their condition stabilized.

[0064] Therefore, the present invention employs the above-mentioned protective device and method for patients with epilepsy during neurological seizures, which can not only prevent patients from suffering adverse consequences such as falls or impacts during seizures, but also promptly notify caregivers to prepare for protection.

[0065] It is worth noting that all the contents not described in detail in this invention are existing technologies and are well known to those skilled in the art.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
