Description

TECHNICAL FIELD

[0001] The present application relates to a head acupuncture treatment device for cognitive impairment patients, and belongs to the technical field of medical instruments. BACKGROUND

[0002] Electroacupuncture therapy is a treatment method combining acupuncture therapy with electrical stimulation. After the needle is inserted into the acupoint and "Qi" is obtained, a small amount of electrical current close to the body's bioelectricity is passed through the needle. The combination of needle and electrical stimulation is used to prevent and treat diseases. It acts on the meridian points of the human body through pulse current of different waveforms to regulate the physiological function of the human body and promote the circulation of Qi and blood, thereby achieving the purpose of treating diseases.

[0003] At present, the position of the electroacupuncture needle inserted into the skin of the patient in the common electroacupuncture treatment device is fixed. For example, the patent application for invention with the Chinese patent application number CN202310722240.1 discloses a patient self-control intensity type electroacupuncture treatment helmet. The position of the electroacupuncture needle inserted into the insertion hole of the treatment helmet is fixed and unchangeable, so the position of the electroacupuncture needle inserted into the skin of the patient is also fixed. The electroacupuncture treatment device with fixed insertion position may have the following problems in actual use: due to the different body types of each patient, the size of the head of each patient will be different, which will cause the difference between the position of the electroacupuncture needle inserted into the skin of the patient and the position of the acupoint on the head of the patient, which will cause the electroacupuncture needle with fixed insertion position to be unable to accurately insert into the acupoint, thereby affecting the subsequent treatment.

[0004] At the same time, it is found that different patients have different tolerances to electric current during electroacupuncture treatment, so different patients have different feelings, which requires the doctor to adjust the electric current in real time according to the feedback of the patient during electroacupuncture treatment. However, for cognitive impairment patients, they cannot accurately express the feelings such as acid, numbness, swelling and pain of the acupoint during acupuncture, which makes it difficult for the doctor to judge whether the acupuncture is uncomfortable according to the feedback of the patient, which is easy to cause certain harm to the cognitive impairment patients.

DETAILED DESCRIPTION

[0030] The application will be described in detail below in combination with the drawings and specific embodiments.

[0031] Embodiment: please refer to Figs. 1-4The embodiment provides a head acupuncture treatment device for cognitive impairment patients, which comprises a helmet body 1. The specific size of the helmet body 1 can be set according to actual conditions. The helmet body 1 can be set to be used for men, women, children and the like according to requirements, and can be 3D printed according to subsequent patient brain image data to completely conform to the head shape of the patient, which is not limited herein. A plurality of through holes 2 for passing through power needles 3 are formed in the helmet body 1. The number of the through holes 2 is set in one-to-one correspondence with the number of head acupoints, and the number of the through holes 2 can be increased or decreased according to actual conditions. The positions of the through holes 2 correspond to the general positions of the head acupoints, so that the head acupoints of the patient can be in the projection range of the through holes 2 when the patient wears the device. The positions of the head acupoints can be obtained according to known human acupoint distribution maps. The diameter of the through holes 2 is greater than the diameter of the power needles 3, and the specific diameter can be determined according to actual conditions, so that the doctor can adjust the positions of the power needles 3 inserted into the through holes 2, and the power needles 3 can be inserted into the corresponding acupoints. Although the sizes of the patients are different, the positions of the acupoints are not greatly deviated. The diameter of the through holes 2 can be about 1 inch to meet the requirement that the head acupoints can be in the projection range of the corresponding through holes 2. The diameter of the through holes 2 can be selected and determined according to actual conditions, which is not limited herein.

[0032] The helmet body 1 is further provided with a main controller 4 for control operation, an acupoint positioning module 5 for acupoint positioning, and a communication module 6 for data communication. The main controller 4 is electrically connected with the acupoint positioning module 5, and the main controller 4 is in communication connection with an external imaging device 7 through the communication module 6. The external imaging device 7 can be an MRI imaging device or a CT three-dimensional reconstruction device, which is used to generate the relevant brain image of the patient. The generated brain image data of the patient is sent to the main controller 4 through the communication module 6, and the main controller 4 sends the data to the acupoint positioning module 5. The acupoint positioning module 5 can determine the acupoint position of the patient's head according to the data, and send the determined acupoint position of the patient's head to the main controller 4. The inner side wall of the helmet body 1 is further provided with a placing groove 9 corresponding to the through hole 2. Each placing groove 9 is in communication with the corresponding through hole 2. The width of the placing groove 9 is greater than the diameter of the through hole 2, so that the doctor can clearly see the patient's head skin through the through hole 2 and the placing groove 9. Each placing groove 9 is provided with an electric universal joint 10. The fixed part of each electric universal joint 10 is fixedly connected with the top wall of the corresponding placing groove 9. Each electric universal joint 10 is provided with a laser emitter 11. The emission part of each laser emitter 11 is arranged towards the direction of the corresponding placing groove 9. The laser emitter 11 and the electric universal joint 10 are electrically connected with the controller. The controller can control the electric universal joint 10 to start working according to the acupoint position of the patient's head determined by the acupoint positioning module 5 and the position of the emission part of the laser emitter 11. After adjusting the emission part of the laser emitter 11 to the appropriate position, the controller controls the laser emitter 11 to start working. At this time, the laser emitted by the laser emitter 11 irradiates the position of the acupoint of the patient's head. The doctor can observe the laser irradiation point through the through hole 2 and then puncture the electric needle 3 into the laser irradiation point, so as to accurately puncture into the acupoint and ensure the subsequent treatment effect.

[0033] Meanwhile, in order to know the feeling of the patient with cognitive impairment during the electro-acupuncture treatment, the inner side wall of the helmet body 1 is further provided with a muscle sensor 8 for contacting the skin of the head of the patient and capable of sensing the muscle contraction of the head of the patient, the muscle sensor 8 is one-to-one corresponding to the placement slot 9, each muscle sensor 8 is arranged at the slot opening position of the corresponding placement slot 9, the muscle sensor 8 comprises an outer shell 12, the outer shell 12 is arranged in a circular ring structure, the inner ring part of the outer shell 12 is arranged on the same central axis as the placement slot 9, the diameter of the inner ring part of the outer shell 12 is not less than the width of the placement slot 9, so that the doctor can clearly see the skin of the head of the patient through the through hole 2, the placement slot 9 and the inner ring part of the outer shell 12, and at the same time, the laser emitted by the laser emitter 11 can also be reflected to the skin of the head of the patient from the inner ring part of the outer shell 12. The bottom outer wall of the outer shell 12 is provided with a surface electrode 13 arranged in a circular ring structure, the surface electrode 13 can contact the skin of the head of the patient when the patient wears the helmet body 1, the inner part of the outer shell 12 is provided with a signal processing circuit 14, an analog-to-digital conversion module 15 and a data transmission module 16, the signal processing circuit 14 is electrically connected with the surface electrode 13, the analog-to-digital conversion module 15 is electrically connected with the signal processing circuit 14, and the data transmission module 16 is in communication connection with the communication module 6. The electrical signal of the muscle of the head of the patient detected by the surface electrode 13 is transmitted to the signal processing circuit 14, the signal processing circuit 14 is a common signal amplification circuit, which processes and amplifies the electrical signal transmitted, the electrical signal processed by the signal processing circuit 14 enters the analog-to-digital conversion module 15 to be converted into a digital signal, the digital signal formed is transmitted to the main controller 4 through the communication of the data transmission module 16 and the communication module 6, and the main controller 4 can preset a corresponding threshold value, when the value received by the main controller 4 is greater than the corresponding threshold value, it indicates that the patient may be uncomfortable at this time, the main controller 4 makes corresponding action to remind the doctor that the patient is uncomfortable, and the treatment strategy should be adjusted in time.

[0034] In the embodiment, the main controller 4 is in communication connection with the external display and the buzzer through the communication module 6, when the value received by the main controller 4 is greater than the threshold value of itself and needs to make the action to remind the doctor, the main controller 4 can display the related value on the external display so that the doctor can adjust the current size of the treatment according to the value, and at the same time, the main controller 4 can also control the external buzzer to start working to remind the doctor of the abnormality and adjust in time. In actual use, the size of the threshold value of the main controller 4 can be determined according to the actual experience of the doctor, which can be determined by collecting a large amount of clinical data of the patient during the electro-acupuncture treatment, such as taking the average value of the sum of the minimum values of the muscle digital signals of 500 patients when they are uncomfortable during the treatment as the threshold value of the main controller 4, or other determination methods, which are not limited here.

[0035] To ensure that the surface electrode 13 on the muscle sensor 8 can contact the skin of the patient's head when the patient wears the helmet body 1, in the embodiment, a connecting column 17 is symmetrically arranged on the top wall of each muscle sensor 8, a connecting groove 18 corresponding to the connecting column 17 is arranged on the inner wall of the helmet body 1, the connecting column 17 is movably arranged in the connecting groove 18, a spring 19 is sleeved on the outer wall of each connecting column 17, and the two ends of each spring 19 are connected to the inner wall of the helmet body 1 and the top wall of the corresponding muscle sensor 8, respectively. When the spring 19 is in a normal state, it can push the muscle sensor 8 away from the inner wall of the helmet body 1, so that the skin of the patient's head can contact the surface electrode 13 on the muscle sensor 8 when the patient wears the helmet body 1, thereby enabling the corresponding detection work to be performed. Because the sizes of the heads of patients are different, the spring 19 can enable the muscle sensor 8 to move a certain stroke, so as to adapt to the wearing of patients with different head sizes. When the muscle sensor 8 moves, the connecting column 17 is arranged in the connecting groove 18, and the spring 19 is compressed to generate elastic potential energy, so that the surface electrode 13 on the muscle sensor 8 can always contact and approach the skin of the patient's head, thereby ensuring the required detection effect.

[0036] To avoid the muscle sensor 8 from falling off the helmet body 1, the slot of each connecting groove 18 is arranged in a necked structure, and a limiting block 20 is arranged on each connecting column 17. The slot of the connecting groove 18 in the necked structure can be passed by the connecting column 17, but the limiting block 20 cannot pass through, so that the connecting column 17 cannot be pulled out of the connecting groove 18, and the muscle sensor 8 cannot fall off the helmet body 1.

[0037] In the embodiment, to ensure the firmness of the helmet body 1 worn on the patient's head, a strap 21 is arranged at the bottom of each side of the helmet body 1. One of the straps 21 is adjustably arranged by means of an adjusting buckle 22, and the ends of the two straps 21 away from the helmet body 1 are connected to each other by means of a connecting buckle 23. After the patient wears the helmet body 1, the medical staff can connect the two straps 21 by means of the connecting buckle 23, so as to fix the helmet body 1 on the patient's head. Meanwhile, the medical staff can adjust the length of the corresponding strap 21 by means of the adjusting buckle 22, so as to adapt to the wearing of patients with different head sizes.

[0038] In the embodiment, the method for determining the acupoint position of the patient's head according to the patient's brain image data includes the following steps: Firstly, the patient's brain image data is preprocessed, common Gaussian filter is used to remove image noise, and common histogram equalization is used to enhance contrast, so as to facilitate subsequent operation. Different methods can be selected according to actual conditions to preprocess the patient's brain image data, which is not limited here.

[0039] Secondly, the edge of the tissue in the patient's brain image data is detected. Specifically, the following steps are included: using Sobel operator to calculate the gradient of the patient's brain image in x and y directions, the convolution kernel of Sobel operator in x direction is as follows:

[0040] In the formula, S x represents the convolution kernel of Sobel operator in x direction.

[0041] The convolution kernel of Sobel operator in y direction is as follows:

[0042] In the formula, S y represents the convolution kernel of Sobel operator in y direction.

[0043] For the pixel point m, n in the patient's brain image, the gradient in x direction is as follows:

[0044] In the formula, G x m, n represents the gradient of pixel point m, n in x direction, S x i+1, j+1 represents the element value of the convolution kernel of Sobel operator in x direction at the i+1th row and j+1th column position, and Im+i, n+j represents the image value of pixel point m+i, n+j.

[0045] The gradient of pixel point m, n in y direction in the patient's brain image is as follows:

[0046] In the formula, G y m, n represents the gradient of pixel point m, n in y direction, S y i+1, j+1 represents the element value of the convolution kernel of Sobel operator in y direction at the i+1th row and j+1th column position, and Im+i, n+j represents the image value of pixel point m+i, n+j.

[0047] The amplitude of the gradient of pixel point m, n in the patient's brain image is as follows:

[0048] In the formula, Gm, n represents the amplitude of the gradient of pixel point m, n in the image, Gx m,n represents the gradient of pixel point m,n in x direction, G y m,n represents the gradient of pixel point m,n in y direction.

[0049] The direction of the gradient of pixel point m,n in the patient's brain image is shown in the following formula:

[0050] In the formula, θm,n represents the direction of the gradient of pixel point m,n in the image, G x m,n represents the gradient of pixel point m,n in x direction, G y m,n represents the gradient of pixel point m,n in y direction.

[0051] Then, the gradient amplitude of each pixel point is compared with the gradient amplitudes of the two adjacent pixel points in the gradient direction. If the gradient amplitude of the pixel point is not a local maximum, it is set to 0. If it is a local maximum, it is set to an edge point. Then, each edge point is connected to form the edge of the tissue in the patient's brain image.

[0052] In the third step, the patient's brain image with detected edges is segmented. Referring to the existing regional distribution map of human head acupoints, the patient's brain image with detected edges is segmented into images with corresponding regions, and the size of each segmented region image V is greater than the corresponding region T of the existing regional distribution map of human head acupoints. The specific steps include: adjusting the patient's brain image with detected edges and the existing regional distribution map of human head acupoints to the same size, then segmenting the patient's brain image with detected edges according to the existing regional distribution map of human head acupoints, and then applying a morphological dilation operation to each segmented region image V to expand the region, i.e. by setting a structure element, which can be square, circular, etc., and setting the number of dilations, preferably 2-4 times, gradually expanding the range of region image V to be greater than the corresponding region T of the regional distribution map of human head acupoints.

[0053] In the fourth step, an acupoint positioning algorithm is constructed. According to the acupoint positioning algorithm, the segmented region V is matched with the corresponding region T of the existing regional distribution map of human head acupoints to determine the acupoint position of the patient's head. The specific steps include: setting the size of the corresponding region T of the existing regional distribution map of human head acupoints as MxN, setting the size of the region image V to be matched as AxB, taking a sub-image U a,b with the same size as region T as the upper left corner a,b on image V, then calculating the coefficient Ra,b, and the calculation formula of the coefficient Ra,b is as follows:

[0054] In the formula, Ra,b represents the coefficient for judging whether it is the best matching position, Ua,b i.j represents the pixel value of the sub-image U at coordinate i, j a,b of the sub-image U, represents the mean value of all sub-images U a,b i.j represents the pixel value of the region T at coordinate i, j, represents the mean value of all regions T.

[0055] The position with the maximum Rx,y is then found by traversing all possible positions on the image V, and this position is the best matching position, i.e. the position of the corresponding region of the patient's head acupoint. Then, by comparing each pixel value of the image V with the corresponding pixel value of the image U, the position of the acupoint on the patient's head is determined. The working principle of the embodiment is as follows. When in use, medical staff helps the patient with cognitive impairment to wear the helmet body 1, and fixes the helmet body 1 on the head of the patient with cognitive impairment by using the binding belt 21, the adjusting buckle 22 and the connecting buckle 23. Then, the doctor starts the main controller 4 to work. The main controller 4 obtains the patient's cranium image data generated by the external imaging device 7 through the communication module 6, and sends the data to the acupoint positioning module 5. The acupoint positioning module 5 determines the acupoint position of the patient's head, and sends the determined acupoint position of the patient's head to the main controller 4. The main controller 4 controls the electric universal joint 10 to start working according to the acupoint position of the patient's head determined by the acupoint positioning module 5 and the position of the laser emitter 11 emitting part, so as to adjust the laser emitter 11 emitting part to the appropriate position. The initial position of the laser emitter 11 emitting part is preset in the controller. The controller can control the electric universal joint 10 to start working to adjust the position of the laser emitter 11 emitting part according to the preset initial position and the determined acupoint position of the patient's head. When the laser emitter 11 starts working, the position of the laser emitted by the laser emitter 11 on the patient's head is the position of the acupoint of the patient's head. Then, the doctor can observe the laser irradiation point through the through hole 2, and then puncture the electric needle 3 into the laser irradiation point, so as to accurately puncture into the acupoint. After the electric needle 3 is punctured into the skin of the patient's head, the muscle sensor 8 detects the muscle at the corresponding position of the patient, and feeds back the detected muscle electric signal to the main controller 4. When the value received by the main controller 4 is greater than the set corresponding threshold value, the main controller 4 makes a corresponding action to remind the doctor that the patient is uncomfortable, and the treatment strategy should be adjusted in time.

The head acupuncture treatment device for patients with cognitive impairment according to claim 8, characterized in that: The step S2 comprises the following steps: using the Sobel operator to calculate the gradient of the patient's brain image in the x and y directions, and the convolution kernel of the Sobel operator in the x direction is shown as follows: Where S x Represents the convolution kernel of the Sobel operator in the x direction. The convolution kernel of the Sobel operator in the y direction is as follows: Where S y Represents the convolution kernel of the Sobel operator in the y direction. For the pixel point (m, n) in the patient's brain image, the gradient in the x direction is as follows: Where G x (m, n) represents the gradient of pixel (m, n) in the x direction, S x (i+1, j+1) represents the element value of the convolution kernel of the Sobel operator in the x-direction at the i+1th row and j+1th column position, and I(m+i, n+j) represents the image value of the pixel point (m+i, n+j). The gradient of the pixel point (m, n) in the patient's brain image in the y direction is as follows: Where G y (m, n) represents the gradient of pixel (m, n) in the y direction, S y (i+1, j+1) represents the element value of the convolution kernel of the Sobel operator in the y direction at the i+1th row and j+1th column position, and I(m+i, n+j) represents the image value of the pixel point (m+i, n+j). The amplitude of the gradient of pixel point (m, n) in the patient's brain image is expressed as follows: In the formula, G(m,n) represents the magnitude of the gradient of the pixel (m,n) in the image, G x (m, n) represents the gradient of pixel (m, n) in the x direction, G y (m, n) represents the gradient of pixel (m, n) in the y direction. The direction of the gradient of the pixel point (m, n) in the patient's brain image is as follows: Where θ(m, n) represents the direction of the gradient of pixel (m, n) in the image, G x (m, n) represents the gradient of pixel (m, n) in the x direction, G y (m, n) represents the gradient of pixel (m, n) in the y direction. The gradient amplitude of each pixel is then compared with the gradient amplitudes of the two adjacent pixels in the gradient direction. If the gradient amplitude of the pixel is not the local maximum, it is set to 0. If it is the local maximum, it is set as an edge point. Each edge point is then connected to form the edge of the tissue in the patient's brain image.
