Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical equipment technology, specifically relating to an external transcranial magnetic stimulation deviation alarm device. Background Technology
[0002] Currently, transcranial magnetic stimulation (TMS) devices are common equipment in major hospitals. Patients sit in the device's chair, and the magnetic stimulation generator is positioned near the patient's head to treat a specific lesion on the head for a period of time.
[0003] However, in actual treatment, a person's body and head will always move involuntarily, causing the magnetic stimulation device to deviate from the lesion, thus reducing the treatment effect.
[0004] In the existing technology, there are already transcranial magnetic stimulation devices with navigation functions that can solve the problem of head displacement in patients; however, most hospitals still have a lot of ordinary transcranial magnetic stimulation devices. Stopping these expensive devices wastes a lot of medical resources and significantly reduces economic benefits. Summary of the Invention
[0005] To address the aforementioned shortcomings in the existing technology, this invention provides an external transcranial magnetic stimulation (TMS) deviation alarm device, which solves the problem that many hospitals still use ordinary TMS devices, which cannot solve the problem of patient head deviation.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] An external transcranial magnetic stimulation offset alarm device includes a movable base, a housing, an offset adjuster, and a position identifier. The offset adjuster is installed on the upper part of the movable base, the housing is located outside the movable base and the offset adjuster, and the position identifier is installed on the offset adjuster.
[0008] Furthermore, the offset adjuster includes a horizontal moving frame, a vertical moving frame, and a telescopic mechanism. The horizontal moving frame is vertically mounted on the vertical moving frame, and the telescopic mechanism is slidably mounted on the upper part of the horizontal moving frame.
[0009] Furthermore, the vertical moving frame includes a vertical motor, a vertical fixed frame, a vertical moving belt, and a vertical moving block. The vertical motor is installed at the bottom of the vertical fixed frame, the vertical moving belt is installed inside the vertical fixed frame and is connected to the vertical motor, and the vertical moving block is fixedly connected to the vertical moving belt.
[0010] Depending on the user's height and the location of the lesion, the vertical motor drives the vertical moving belt to rotate, which in turn drives the vertical moving block to adjust up and down, thereby adjusting the height of the horizontal moving frame so that the position recognizer always matches the user's height.
[0011] Furthermore, the transverse moving frame includes a transverse motor, a transverse fixed frame, a transverse moving belt, and a transverse moving block. The transverse motor is installed at the left end of the transverse fixed frame, the transverse moving belt is installed inside the transverse fixed frame and is connected to the transverse motor, and the transverse moving block is installed on the upper part of the transverse moving block.
[0012] Depending on the user's body shape and the location of the lesion, the horizontal motor drives the horizontal moving belt to rotate, which in turn drives the left and right sliding joints of the horizontal moving block, thereby adjusting the left and right position of the position recognizer so that the position recognizer always matches the location of the user's lesion.
[0013] Furthermore, the telescopic mechanism includes a telescopic motor, a telescopic shaft, a connecting piece, and a mounting screw. The telescopic shaft is movably connected to the telescopic motor, the connecting piece is fixedly installed on the right end of the telescopic shaft, and the mounting screw is fixedly connected to the connecting piece.
[0014] The telescopic motor drives the telescopic shaft to extend the connecting piece outward, allowing the position identifier to extend outward, increasing the activity area between the device and the user, and increasing the device's spatial adaptability.
[0015] Furthermore, the mobile base is equipped with a control motherboard, which is electrically connected to the position identifier and the offset adjuster.
[0016] Furthermore, the location identifier includes an infrared sensor and a visual identifier.
[0017] Furthermore, the location recognizer also includes a voice module.
[0018] Furthermore, a storage battery is also installed inside the mobile base.
[0019] Compared with the prior art, the present invention has the following beneficial effects: Most hospitals have a large number of ordinary transcranial magnetic stimulation devices. It is impossible to scrap all of these expensive devices. By using an alarm device in conjunction with an ordinary transcranial magnetic stimulation device, an alarm can be triggered when the patient's head deviates during treatment, preventing the body and head from moving involuntarily and causing the magnetic stimulation device to deviate from the lesion, which would lead to a decrease in the treatment effect. At the same time, by using an external alarm device, the ordinary transcranial magnetic stimulation device can continue to be used, thereby improving economic efficiency. Attached Figure Description

[0031] Example
[0032] like Figures 1-5 As shown, an external transcranial magnetic stimulation (TMS) deviation alarm device includes a movable base 1, a housing, a deviation adjuster 2, and a position identifier 3. The deviation adjuster 2 is installed on the upper part of the movable base 1, the housing is located outside the movable base 1 and the deviation adjuster 2, and the position identifier 3 is installed on the deviation adjuster 2. A transcranial magnetic stimulator (TMS) is an instrument used in clinical medicine. Its working principle is to act on the cerebral cortex to generate induced currents to change the action potential of cortical nerve cells. The magnetic signal can penetrate the skull without attenuation to stimulate the cerebral cortex and peripheral nerves, purposefully and precisely adjusting the neurotransmitter power to produce excitation or inhibition, thereby affecting brain metabolism and neural electrical activity. During treatment, it alarms for head deviation to prevent the body and head from involuntarily moving, causing the magnetic stimulation device to deviate from the lesion and resulting in poor treatment effects.
[0033] The offset adjuster 2 includes a horizontal moving frame 21, a vertical moving frame 22, and a telescopic mechanism 23. The horizontal moving frame 21 is vertically mounted on the vertical moving frame 22, and the telescopic mechanism 23 is slidably mounted on the upper part of the horizontal moving frame 21. The vertical moving frame 22 includes a vertical motor 221, a vertical fixed frame 222, a vertical moving belt 223, and a vertical moving block 224. The vertical motor 221 is mounted at the bottom of the vertical fixed frame 222, the vertical moving belt 223 is mounted inside the vertical fixed frame 222 and is connected to the vertical motor 221, and the vertical moving block 224 is fixedly connected to the vertical moving belt 223. According to the user's height and the location of the lesion, the vertical motor 221 drives the vertical moving belt 223 to rotate, thereby driving the vertical moving block 224 to adjust up and down, thus adjusting the height of the horizontal moving frame 21 so that the position recognizer 3 always matches the user's height.
[0034] The lateral moving frame 21 includes a lateral motor 211, a lateral fixing frame 212, a lateral moving belt 213, and a lateral moving block 214. The lateral motor 211 is installed at the left end of the lateral fixing frame 212. The lateral moving belt 213 is installed inside the lateral fixing frame 212 and is connected to the lateral motor 211. The lateral moving block 214 is installed on the upper part of the lateral moving block 214. Depending on the user's body shape and the location of the lesion, the lateral motor 211 drives the lateral moving belt 213 to rotate, which in turn drives the lateral moving block 214 to slide left and right, thereby adjusting the left and right position of the position recognizer 3 so that the position recognizer 3 always matches the user's lesion position.
[0035] The mobile base 1 is equipped with a control motherboard, which is electrically connected to the position recognizer 3 and the offset adjuster 2. The position recognizer 3 includes an infrared sensor 31 and a visual recognizer 32. The position recognizer 3 also includes a voice module. The mobile base 1 is also equipped with a battery.
[0036] The telescopic mechanism 23 includes a telescopic motor 231, a telescopic shaft 232, a connecting piece 233, and a mounting screw 234. The telescopic shaft 232 is movably connected to the telescopic motor 231. The connecting piece 233 is fixedly installed on the right end of the telescopic shaft 232. The mounting screw 234 is fixedly connected to the connecting piece 233. The telescopic motor 231 drives the telescopic shaft 232 to extend the connecting piece 233 outward, allowing the position identifier 3 to extend outward, increasing the activity area between the device and the user, and increasing the spatial adaptability of the device.
[0037] The telescopic motor 231 is a transmission actuator that uses the rotation of an electric motor to drive a bearing through the cooperation between gears, thereby pushing a trapezoidal threaded screw to achieve telescopic movement over a short distance. It can also be called an electric push rod.
[0038] The position recognizer 3 includes an infrared sensor 31 and a vision recognizer 32. The position recognizer 3 also includes a voice module. The infrared sensor 31 and the vision recognizer 32 work together to recognize the right side of the patient and set the position of the patient's head. When the patient's head turns or shifts up, down, left, right, forward, or backward, the system can recognize the behavior and issue a voice alarm to remind the patient to return to the set position. For example, if the patient's head shifts forward by 5cm, the voice should remind the patient to move back 5cm.
[0039] The infrared sensor 31 includes an optical system, a detection element, and a conversion circuit (not shown in the diagram). The detection element can be divided into thermal detection elements and photoelectric detection elements according to its working principle. The most commonly used thermal element is the thermistor. When a thermistor is exposed to infrared radiation, its temperature rises, and its resistance changes (this change may increase or decrease, as thermistors can be divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors). This change is converted into an electrical signal output by the conversion circuit. The photoelectric detection element is model E18-D80NK, and photosensitive elements are commonly used. The infrared sensor 31 has a pair of infrared emitting and receiving tubes. The emitting tube emits infrared light of a certain frequency. When the detection direction encounters an obstacle (reflective surface), the infrared light is reflected back and received by the receiving tube. After processing by the comparator circuit, the green indicator light will illuminate, and the signal output interface will output a digital signal. The detection distance can be adjusted via a potentiometer knob, with an effective range of 2–30 cm. The operating voltage is 3.3V–5V.
[0040] The visual recognition device 32 includes a three-lens camera, a photodiode and photoelectric conversion device, a position-sensitive detector, a CCD image sensor, and a CMOS image sensor (not shown in the figure). The three-lens camera acquires video signals, converts the video information into digital images, and then performs operations such as grayscale conversion, edge detection, and contour coordinate reconstruction on the digital images through a video processing card and video processing program. Finally, the shape and center position information of the target object are transmitted to the control motherboard to drive the offset adjuster to adjust the position.
[0041] The above descriptions are merely embodiments of the present invention. Commonly known structures and characteristics of the solutions are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, under the guidance of this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention. These should also be considered within the scope of protection of the present invention, and will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
