METHODO OF MEASURING NERVOUS SYSTEM DISORDERS USING PORTABLE DEVICE AND PORTABLE DEVICE}

The present invention relates to a neurological abnormality test method and a portable device for examining the symptoms caused by the nervous system abnormalities, and more particularly, to a neurological abnormality test method and a portable device that can quickly examine the symptoms caused by the nervous system abnormalities. .

90% of the disorders that occur in Korea occur according to acquired diseases or accidents. The causes of disorders are the causes of acquired disorders such as disease 55.6% and accidents 34.4%. The most common type of disability was 43.5%, followed by 16% of brain lesions, 12.9% of hearing impairments, and 10.9% of visual impairments. 68.5% of people with disabilities have to spend an additional 15,000 won per month due to their disability, and the social cost of disability and impairment amounts to 13,770 trillion won, which is 1.9% of GDP.

Among the causes of the disorders, brain lesions appear as neurological disorders, such as stroke, brain tumors, infections, and other central nervous system disorders, which are the most common causes of paralysis.

Stroke, a representative neurological abnormality, results from a disorder of blood flow to brain tissue. For example, when blood vessels leading to the brain are blocked by embolism or thrombus, or when a rupture occurs, the flow of blood to a specific part of the brain may be blocked. The blood flow disorder may occur temporarily, but if the blood flow disorder persists, the brain cells may not receive normal nutrition and oxygen, leading to death. In the case of ischemic strokes in arteries that supply blood to the brain with embolism or thrombus, treatment involves tissue plasminogen activator that enzymatically cleaves proteins that cause blood clots to eliminate blood clots. Thrombolytic release). However, if the administration of thrombolytics is too late, side effects such as bleeding are caused, so the administration of thrombolytics is limited within 3 hours after symptoms.

Therefore, early diagnosis of neurological diseases such as stroke is an important problem directly related to the life of the patient. In addition, rehabilitation treatment to ameliorate paralysis symptoms in neurological diseases is also preferably performed early.

However, the diagnosis of a neurological disease based on the paralysis symptom of a patient is visually evaluated by a specialist, and therefore, it is cumbersome to find a medical institution, and evaluation is different for each examiner.

Thus, when paralysis occurs due to abnormalities of the nervous system due to stroke or the like, a tool for easily and sensitively measuring paralysis symptoms is required.

The present invention provides a nervous system abnormality test method and a portable device capable of easily and sensitively inspecting symptoms caused by neurological abnormality such as paralysis.

The present invention provides a neural system abnormality test method and a portable device that can readily measure paralysis symptoms due to nervous system abnormalities, even without a visit to a medical institution for professional diagnosis.

The present invention provides a neurological abnormality test method and a portable device that can quantify the degree and degree of paralysis and transmit it to a specialist in real time.

According to an exemplary embodiment of the present invention for achieving the above object of the present invention, the nervous system abnormality test method is to examine the nervous system abnormality using a portable device including a gravity accelerometer, the first drift of the measurement ) Storing the angle and the primary pronation angle, storing the secondary drift angle and secondary secondary angular angle after a certain time, comparing the primary and secondary drift angles, and comparing the primary and secondary internal angular angle Comparing the step, and using the comparison result may include outputting information on the nervous system abnormalities of the human body.

When the handheld device is provided on the palm of a horizontally extended arm, the gravitational accelerometer can measure the angle of drift tilted downward relative to the horizontal direction of the arm and the angle of rotation of the arm twisted by the axis of rotation. Thus, prior to the step of storing the primary drift angle and the primary intra-angular angle, it may be checked whether the portable device is located in the palm of the hand.

In addition, prior to the step of storing the first drift angle and the first intra-angular angle, the portable device may indirectly confirm whether the portable device is positioned on the palm of the hand by providing guide information on the use process and the use posture. For example, some time after the instruction to place the handheld device in the palm of the hand to measure the drift angle and the internal angle of the arm, the measured drift and internal angle as the primary drift angle and the internal angle are measured. Information about the use process and posture, such as notifications at the time of measurement that storage has begun and arms extended horizontally for at least several seconds, can be provided. can do.

In addition, before the storing of the first drift angle and the first in-rotation angle, the method may further include a calibration step of determining the drift angle and the in-rotary angle value of the portable device with the hand placed on the palm of the hand. .

For reference, the portable device stores the first drift angle and the internal angle measured by the gravitational accelerometer, and stores the measured drift angle and the internal angle as the secondary drift and internal angle after a certain time, and the measurement time is measured by the patient. It can be set in seconds depending on muscle strength or paralysis. In the clinic, a time of 20 to 30 seconds is used, but it can be changed according to the condition of the patient.

In addition, the drift angle and the angle within the rotational angle is for the change of the angle of the arm, in the present specification, to place the portable device on the palm to measure the drift angle and the angle within the palm of the hand to grip the portable device by hand easily and the angle to the arm To measure the change in In this sense, the palm of the present invention may mean an arm.

In addition, the hand may have an arm and an angle shift, and since the change in the drift angle and the internal angle is a test of muscle weakness of the proximal muscle close to the shoulder, a separate fixing means such as an arm band is used. It is also possible to fix the portable device to the arm to measure the drift angle and the angle in the spine.

By arranging only one of the portable devices described above in the palm of the arm with paralysis, paralysis may be examined through the drift angle and the internal angle. However, because the weight of the portable device itself may cause sagging or an internal reaction of the arm, which is not related to paralysis, the portable device has a similar weight on both hands rather than placing the portable device on only one hand to test for paralysis. By providing a more accurate paralysis test can be carried out. To this end, the mutual information transmission function using a data communication protocol between two portable devices can be used.

Specifically, the portable device may include a host portable device and a client portable device respectively provided on both palms of the arms extended horizontally, and the drift angle and the internal angle measured by the client portable device may be transmitted to the host portable device.

The host portable device compares the difference between the primary and secondary drift angle values received from the client portable device with the difference between the primary and secondary drift angle values measured by the host portable device, and similarly receives 1 from the client portable device. The difference between the primary and secondary in-situ angle values can be compared with the difference between the primary and secondary in-situ angle values measured by the host portable device.

Through the comparison, the drift angle and the internal angle of the paralyzed arm can be calculated more precisely by excluding the natural sag or the internal reaction of the arm without paralysis from the value of the sagging or internal response of the paralyzed arm. .

In this case, the host portable device and the client portable device may use the same type of portable device or different types of portable devices.

For example, the client handheld device has been described as including a function of transmitting an angle measured from the arm to the host handheld device, but in fact, only one of the two handheld devices may include a transmission function, and both handheld devices Because it does not include a transmission function, two portable devices may be provided in the same model or different models if the data protocol can be transmitted.

1 to 4, a nervous system abnormality test method for examining a nervous system abnormality of a human body may use a portable device including a gravity accelerometer.

In patients with paralysis beyond the nervous system, after a period of time with both arms stretched out, the paralyzed arm has a drift response and the arm is twisted with the extended arm as the axis of rotation Intravaginal reactions occur. Therefore, the degree of paralysis can be diagnosed by measuring the drift angle and the in-rotation angle.

The nervous system abnormality test method according to the present invention comprises the steps of: storing the primary drift angle and the primary intra-angular angle at the beginning of the measurement; storing the secondary drift angle and the secondary intra-angular angle after a predetermined time; primary and secondary drift Comparing the angles, comparing the primary and secondary intra-division angles, and outputting information on the nervous system abnormalities of the human body using the comparison results, the symptoms caused by the nervous system abnormalities can be examined.

For reference, the test method according to the present invention may be performed by a microchip included in a specific device or a program installed separately. That is, the test method according to the present invention may be applied to equipment for measuring nervous system abnormality, and may be stored and used in equipment including a component of a gravity accelerometer or similar function as a program or application. In addition, the program for the test method may be provided in a storage medium such as a disk and a CD separate from the portable device.

Therefore, it is possible to simply diagnose a paralysis symptom by using one handheld device, placing it in the palm of the arm where paralysis is predicted, and measuring the drift angle and the in-rotary angle by using a gravity accelerometer of the handheld device. However, because the weight of the portable device itself may cause sagging or an internal reaction of the arm, which is not related to paralysis, the portable device has a similar weight on both hands rather than placing the portable device on only one hand to test for paralysis. By providing a more accurate paralysis test can be carried out.

In the present embodiment, a nervous system abnormality test method using two portable devices will be described in detail. The host portable device 110 and the client portable device 120 according to the present embodiment are each equipped with a gravity accelerometer.

In the present specification, the host handheld device 110 and the client handheld device 120 include a gravity accelerometer and include a predetermined microprocessor for performing a multimedia playback function. It is an intelligent portable device that adds computer-assisted functions such as information retrieval and information retrieval, and may include a smart phone for installing a desired application.

Of course, both the host portable device 110 and the client portable device 120 need not be smartphones, and the client portable device 120 functions as a client portable device only with a general mobile phone including a gravity accelerometer and general communication functions. It can be performed sufficiently, and can also be provided as part equipment including only a gravity accelerometer for examination of nervous system abnormalities.

In order to measure the nervous system abnormality, the host portable device 110 and the client portable device 120 described above are disposed on both palms (S210).

In this case, when the portable devices are operated to use the measurement mode for measuring the nervous system abnormality of the host portable device 110 and the client portable device 120, any one of the host portable device 110 and the client portable device 120 may be used. In the guide information may be provided. For example, the guide information indicating that the device enters the measurement mode after 5 seconds may be provided visually or audibly through the display or the speaker of either the host portable device 110 or the client portable device 120. Accordingly, the user can hear this guidance information and place the host portable device 110 and the client portable device 120 on both palms in time.

In addition, before storing the primary and primary internal angles measured through the gravitational accelerometer at the beginning of the measurement in each of the handheld devices 110 and 120, the portable device 110 and 120 may be held at least 20 seconds. It may provide guide information, and may provide voice information and elapsed time of the posture to extend the arm horizontally during the examination.

As described above, the host handheld device 110 and the client handheld device 120 are placed on both palms in time, and after 5 seconds according to the guide information, each of the handheld devices 110 and 120 measures 1 initially. The difference between the drift angle and the primary internal angle is stored in a storage unit provided to each of the portable devices 110 and 120 (S220).

Thereafter, after a certain time, each of the portable devices 110 and 120 stores the secondary drift angle and the secondary internal angle in a storage unit provided to each of the portable devices 110 and 120 (S230).

In this case, the predetermined time may be approximately 20 seconds to 30 seconds, preferably 20 seconds. This time can be changed according to the patient through option setting.

In addition, in order to inform the user of the predetermined time, that is, 20 seconds, the user may provide guidance information on the progress or end of the inspection in any one of the host portable device 110 and the client portable device 120. . For example, as shown in FIG. 3, the display 112 or speaker 114 of the host portable device 110 may guide the countdown visually or audibly while the 20 seconds count down to zero seconds. have.

Thereafter, the host portable device 110 receives the primary and secondary drift angles and the primary and secondary drift angle values measured from the client portable device 120 (S240). Here, the client portable device 120 includes a transmitter for transmitting the drift angle and the internal angle measured by the client portable device 120 to the host portable device 110, and the host portable device 110 corresponds to the transmitter. It includes a receiver.

Thereafter, the host portable device 110 compares the difference between the primary and secondary drift angle values received from the client portable device 120 with the difference between the primary and secondary drift angle values measured by the host portable device 110. Similarly, the difference between the primary and secondary intrinsic angle values received from the client portable device 120 may be compared with the difference between the primary and secondary intrinsic angle values measured by the host portable device 110 (S250). The comparison may be performed through a calculation unit provided in the host portable device 110.

Through the comparison, the drift angle and the internal angle of the paralyzed arm can be calculated more precisely by excluding the natural sag or the internal reaction of the arm without paralysis from the value of the sagging or internal response of the paralyzed arm. .

As described above, the information related to the paralysis of the arm generated due to the nervous system through the comparison process, that is, the drift angle value and the internal angle value of the paralyzed arm is displayed on the host portable device 110 as shown in FIG. 4. The image is output through the reference numeral 112.

For example, the drift angle values measured first and second in the client portable device 120 are 10 degrees and 45 degrees, respectively, and the drift values measured first and second in the host portable device 110 are also 5 values. 10 and 10 degrees, the angle difference measured at the client portable device 120 is 35 degrees, and the angle difference measured at the host portable device 110 is 5 degrees. Thus, the drift value finally provided through the display 112 of the host portable device 110 is 30 degrees.

Similarly, the first and second measured angle values at the client portable device 120 are 0 degrees and 5 degrees, respectively, and the first and second measured internal angle values at the host portable device 110 are 0 degrees and 15 degrees, respectively. In FIG. 3, the angle difference measured at the client portable device 120 is 5 degrees, and the angle difference measured at the host portable device 110 is 15 degrees. Thus, the in-house value finally provided through the display 112 of the host portable device 110 is 10 degrees.

For reference, in the present embodiment, the step of outputting information on the nervous system abnormality of the human body, as described above, in addition to the speaker and display provided by the portable device, the portable device transmits a wireless or wired signal to an external device. It may mean to be.

Here, the external device is an electrical and electronic device which means all kinds of wired / wireless communication devices such as a mobile phone, a personal digital assistant (PDA), a notebook computer, a smart phone, etc., capable of receiving a signal transmitted from the portable device. By mounting a predetermined microprocessor to perform a playback function, it can be used as a concept of collectively a terminal having a predetermined computing power.

Therefore, the external device may output the information received from the portable device through the display or the speaker again.

In particular, the information output from the portable device can be transmitted to an external device connected to the medical information system of the hospital registered by the user, and in some cases, when the information on the nervous system abnormality is out of the normal range, it is directly transmitted to the personal mobile phone of the specialist in charge. Can be sent, allowing for faster prescriptions.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
