Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to an early warning device for epilepsy patients. Background Art

[0002] Epilepsy, commonly known as epilepsy, is a chronic disease characterized by sudden abnormal discharges of brain neurons, leading to transient brain dysfunction. It manifests as sudden onset, automatic termination, and recurring motor, sensory, mental, and consciousness disorders. This definition summarizes the complexity of epilepsy symptoms, and further summarizes the two basic characteristics of epilepsy, namely recurrence and paroxysmal. Recurrence means that after the first seizure, there will definitely be a second, third, or even multiple seizures after a period of time. Even the most common convulsion, if it only occurs once, is not recurring and cannot be diagnosed as epilepsy. Paroxysmal means that symptoms appear suddenly and stop suddenly. We may have seen patients suddenly fall to the ground and convulse while walking or eating, and then return to normal after a period of time.

[0003] Tonic-clonic seizures (grand mal seizures): The most common type of epileptic seizure. They manifest with a sudden loss of consciousness, followed by tonic contractions of the entire body's muscles, followed by clonic convulsions, cyanosis, urinary incontinence, tongue biting, foaming at the mouth (white or bloody), and dilated pupils. The convulsions last for tens of seconds or minutes before spontaneously stopping, and the patient enters a coma. Upon awakening, the patient experiences a brief period of dizziness, irritability, and fatigue, with no recollection of the seizure.

[0004] When a seizure occurs while the patient is lying flat, systemic muscle spasms can cause varying degrees of airway compression and obstruction, impairing normal ventilation. In severe cases, this can lead to respiratory distress or even cessation, endangering the patient's life. If the patient fails to lie on their side immediately after the seizure, vomitus or saliva may be aspirated into the trachea, increasing the risk of suffocation. Therefore, timely detection of epileptic seizures is crucial to ensure that emergency treatment is provided.

[0005] However, since epileptic seizures are sudden and accompanied by loss of consciousness, it is difficult for patients to shout for help. During clonic convulsions, the patient's body movements are small, the sound of the collision is small, and its transmission distance is limited, making it difficult for the patient's family or medical staff to detect it in time.

[0039] See also Figure 1-6 The utility model provides a technical solution: an early warning device for epilepsy patients, comprising a bottom plate 11 and a pressing plate 12 arranged above the bottom plate 11, an elastic support member is provided between the pressing plate 12 and the bottom plate 11, and a gap exists between the pressing plate 12 and the bottom plate 11 when the elastic support member is in a naturally extended state;

[0040] A slider 15 is slidably connected to the top surface of the bottom plate 11 along the length direction. A transmission assembly is provided between the slider 15 and the pressure plate 12. When the pressure plate 12 and the bottom plate 11 move closer to or farther away from each other, the slider 15 is driven to slide by the transmission assembly.

[0041] A sound-generating portion is further provided on the top surface of the bottom plate 11 . The sound-generating portion is located on the sliding track of the slider 15 , and the sound-generating portion can make a sound when it is hit by the slider 15 .

[0042] During use, when the patient lies flat on the bed, the base plate 11 is placed stably on the bed surface, and the pressure plate 12 is used to lift and support the patient's waist, so that the device acts as a lumbar pillow. The device can effectively fill the gap between the waist and the bed surface, provide additional support for the waist, help maintain the natural curvature of the lumbar spine, and reduce the pressure on the lumbar intervertebral disc. An elastic support member is provided between the pressure plate 12 and the base plate 11, and the elastic support member flexibly supports the pressure plate 12 so that the pressure plate 12 and the base plate 11 can move relative to each other. When the patient has an epileptic seizure, the pressure on the pressure plate 12 by the body twitching changes, and under the action of the elastic support member, the pressure plate 12 and the base plate 11 move relative to or away from each other; a slider 15 and a sounding part are provided on the top surface of the base plate 11. When the pressure plate 12 and the base plate 11 move closer to or farther away from each other, the transmission assembly drives the slider 15 to slide on the base plate 11, causing the slider 15 to hit the sounding part and produce a sound, thereby alerting the surrounding family members or medical staff, so that the patient's epileptic seizure can be discovered in time and corresponding emergency treatment can be carried out.

[0043] In this embodiment, both ends of the top surface of the bottom plate 11 are fixedly connected to the side plates 14, and two guide grooves 141 along the vertical direction are formed on the two side plates 14;

[0044] Two protrusions 121 are fixedly connected to both ends of the pressing plate 12 , and the two ends of the pressing plate 12 are respectively embedded in the two guide grooves 141 through the two protrusions 121 and slide in conjunction with each other.

[0045] By providing two side panels 14 at both ends of the base plate 11, and by having the top ends of the side panels 14 protrude from the top surface of the pressure plate 12 when the elastic support member is naturally extended, the patient's body is restricted from moving off the pressure plate 12 to a certain extent. At the same time, by providing two vertical guide grooves 141 on the two side panels 14, and by slidingly engaging the protrusions 121 at both ends of the pressure plate 12 with the two guide grooves 141, the pressure plate 12 is restricted from freely flipping and tilting on the base plate 11, allowing the pressure plate 12 to slide on the side panels 14 in a single degree of freedom in the vertical direction, thereby smoothly squeezing the elastic support member.

[0046] In this embodiment, a groove 111 extending along the length direction is formed on the top surface of the bottom plate 11, and two side walls of the groove 111 are formed with two sliding grooves 112 extending in the same direction as the groove 111.

[0047] There are two sliders 15 , which are respectively located at two ends of the bottom plate 11 , and the two sliders 15 are respectively inserted into the two sliding grooves 112 and slidably engaged with each other.

[0048] In this embodiment, the transmission assembly includes two connecting rods 16, one end of the two connecting rods 16 is hinged to the middle of the bottom wall of the pressure plate 12, and the other end is hinged to the two sliders 15 respectively.

[0049] By setting two connecting rods 16, the two sliders 15 are connected to the pressure plate 12, and when the pressure plate 12 slides on the side plate 14, the two connecting rods 16 drive the two sliders 15 to slide synchronously in opposite directions, so that the two sound units emit sounds at the same time, thereby improving the warning effect.

[0050] In this embodiment, the sound-generating portion includes two sound-generating units corresponding to the two sliders 15. The sound-generating units include elastic sound-generating sheets 21. The elastic sound-generating sheets 21 are perpendicular to the sliding tracks of the corresponding sliders 15, and the bottom ends thereof are fixedly connected to the bottom surface of the groove 111.

[0051] The bottom wall of the slider 15 is provided with a paddle 151 , the top of the paddle 151 is fixedly connected to the slider 15 , and the distance between the bottom of the paddle 151 and the bottom of the groove 111 is smaller than the distance between the top of the elastic sounding plate 21 and the bottom of the groove 111 .

[0052] In this embodiment, the elastic sound-generating piece 21 is parallel to the plectrum 151 .

[0053] During use, when a patient experiences an epileptic seizure, their body twitches and intermittently strikes the pressure plate 12. Under the combined action of the elastic support member and the patient's body, the pressure plate 12 alternates between sliding downward and upward on the side plate 14. The transmission assembly drives the slider 15 to slide within the slide groove 112. The paddle 151 at the bottom of the slider 15 and the corresponding elastic sounding piece 21 undergo relative motion, causing the paddle 151 to strike the elastic sounding piece 21. The elastic sounding piece 21 is squeezed, deformed, and bent, allowing the paddle 151 to slide smoothly over the elastic sounding piece 21. When the paddle 151 breaks away from contact with the elastic sounding piece 21, the elastic sounding piece 21 releases energy and vibrates, producing a sound, thereby achieving the purpose of warning. By providing two sliders 15 and two sounding units, when the pressure plate 12 and the base plate 11 undergo relative motion, the transmission assembly drives the two sliders 15 to slide, respectively striking the elastic sounding piece 21 of the corresponding sounding unit, thereby increasing the sound source and improving the warning effect.

[0054] In this embodiment, a plurality of elastic sound-generating sheets 21 are provided in each of the two sound-generating units, and the plurality of elastic sound-generating sheets 21 are arranged in a linear array along the length direction of the groove 111 .

[0055] By arranging multiple elastic sound-generating plates 21 in a sound-generating unit, the multiple sound-generating plates passed by the slider 15 during the sliding process will make sounds in sequence, so that when the slider 15 slides back and forth in the slide groove 112, the early warning device will make sounds continuously, thereby increasing the probability of the patient's family members or medical staff hearing the warning sound.

[0056] In this embodiment, the pressing plate 12 is an arched structure with a central portion convex upward, and the top surface of the bottom plate 11 is an arched curved surface adapted to the pressing plate 12 .

[0057] By setting the pressing plate 12 into an arched structure with an upward convex middle portion, the pressing plate 12 can fit the patient's waist more closely, thereby improving the comfort of the patient's waist.

[0058] In this embodiment, a plurality of ventilation holes 122 are formed on the top surface of the pressing plate 12 .

[0059] By providing vent holes 122 on the top surface of the pressing plate 12, air circulation on the upper and lower sides of the pressing plate 12 is promoted, and the air permeability of the pressing plate 12 is improved, thereby improving the comfort of the patient's waist skin in the area in contact with the pressing plate 12.

[0060] In this embodiment, a blind hole 113 extending in the vertical direction is opened in the middle of the top surface of the bottom plate 11, and the elastic support member is a spring 13, and the spring 13 is embedded in the blind hole 113;

[0061] One end of the spring 13 is fixedly connected to the bottom surface of the blind hole 113 , and the other end is fixedly connected to the bottom surface of the pressing plate 12 .

[0062] By forming a blind hole 113 on the top surface of the bottom plate 11 and embedding the spring 13 into the blind hole 113 , the spring 13 is restricted from freely moving in the horizontal direction, thereby reducing the probability of the spring 13 being twisted and damaged.

[0063] The sound-generating principle of this warning device is similar to that of a bicycle bell. A bicycle bell typically contains a thin metal sheet (such as steel or copper, with good elasticity), a bell pestle (or a spring hammer), and a lever. The sound-generating process is as follows: When the cyclist presses the bell's lever, the lever pushes the bell pestle (or uses the gear rotation to drive the spring hammer) to move, causing the bell pestle (or spring hammer) to collide with the thin metal sheet, causing the metal sheet to vibrate. The vibration of the metal sheet quickly propagates to the surrounding air, forming sound waves. The elastic sound-generating sheet 21 corresponds to the thin metal sheet, the slider 15 and the paddle 151 correspond to the bell pestle, and the connecting rod 16 corresponds to the lever.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
