DESCRIPTION

DEVICE AND SYSTEM FOR THE DIAGNOSIS AND TREATMENT OF

BENIGN PAROXISTIC POSITIONAL VERTIGOS

Field of the invention

The present invention refers to a device that allows healthcare personnel to improve the tasks of performing diagnostic and treatment maneuvers in Benign Paroxysmal Positional Vertigo (BPPV) disorders, where this device is a portable equipment that allows healthcare personnel to power carry out said tests in a versatile way where it is necessary, and where this invention allows the development of non-invasive diagnosis that allows health personnel to improve the execution of the precise maneuvers for an assessment of said BPPV.

The technical and industrial field where the present invention is framed is the sector related to devices, equipment and systems used by healthcare personnel, and more specifically, in the means used in the diagnosis and treatment techniques in Benign Paroxysmal Positional Vertigo disorders.

State of the art

It is known that in this technological field, systems have been developed that assist health personnel in the execution of diagnostic and treatment maneuvers for Benign Paroxysmal Postural Vertigos, and in this sense, there are several needs demanded by health personnel who treat patients. patients who suffer from these disorders, one of them being that they can guide the operator, that is, they require a system that can indicate in a simple, intuitive and portable way the sequence of maneuvers they have to perform.

Systems that perform the maneuvers and detect the symptoms of vertigo by mechanically manipulating the patient are known, which are based on bulky equipment that need specific locations and require specialized personnel. These automated systems suffer from portability or autonomy, they cannot be executed by non-specialized medical personnel and require a specific place for their location due to their size and a significant investment, which restricts its use to specialty services in hospitals with highly qualified personnel in the field.

On the other hand, there are compact and less automated systems used for the detection of symptoms of the disorder, examining the movement of the eyes. These systems use glasses or attachments for the patient's eyes that allow detecting the movement of the same that, after analysis by specific software, allows the diagnosis of the disorder, and also includes acoustic or visual warning signals to technicians for the evaluation of the symptoms from said eye movement and therefore to diagnose the disorder, but do not indicate to the operator the sequence of movements that must be performed to mitigate it. Below, certain known documents are highlighted that are related to the aforementioned.

Document WO0130255 describes a system based on glasses that are attached to the head and eyes of a user, and that can be used for the treatment of BPPV. However, this invention does not use quaternions and does not explain singular point resolution between quadrants. In addition, it consists of a self-diagnosis and self-treatment system that may be ineffective due to the inexperience of the patient, while the helmet is intended for use by experienced practitioners. In this sense, there is no progression-speed, and therefore, it is not possible to know how much is left of the movement that has to be executed, it is not a valid system for people who need corrective lenses or are blind; and it is a system that does not comprise means autonomously, or without the need for external devices, to carry elements such as patient records or the like.

What is disclosed in document EP3075306 is also known, where a system that is attached to the head of a user and that has indicator lights is described, however, the representation of the guide is not portable (the measurement is) and does not describe how it does; It has the additional drawback that the display cannot be portable due to the conception of the screen where a series of tabs must be marked; requires external elements with wiring; and where the projection of movements to be carried out does not coincide with the reference system of the patient's movements, which is not intuitive and requires additional experience and interpretation by a physician.

Additionally, systems such as those described in document IN201811017105 are known and in document EP340221, where two solutions similar to adjustable glasses are disclosed, which can give sound signals, however, it is a sound guide to the individual who uses it, but not to the doctor with what is another self-diagnosis system that it can be ineffective due to the inexperience of the patient in the detection of nystagmus; In addition to the fact that they are systems that cannot be used by all people, such as the deaf, regardless of whether they can wear hearing aids, and furthermore, they are not systems that allow in their structure to house all the necessary means for their correct operation and require external devices.

In any of these previous cases, and / or in other existing solutions in the state of the art, there is no autonomous and portable device that does not require additional fixed equipment, and that is fully attached to the patient's head. All the above solutions are based on glasses (or similar devices) that fit and adjust in the position of the eyes, and pretend to analyze the movements of the head from the movement of the eyes, however, in all those cases, in addition Of the previously indicated drawbacks, there is undoubtedly a difficulty in interpreting the turns of the head or neck from the eyes, in any case they can be measured with certain restrictions, but they do not allow interpretation. In addition, none of these solutions allows representing the movements with respect to the same reference X, Y, Z of the patient, since none is really solidary to the patient, while with the present invention it develops a device that allows both the measurement and the representation of turns and movements since they are compact devices and attached to the patient's head, and allows said information to be used and managed by the physician and valid for any type of patient regardless of their visual or auditory limitations.

Taking into account the systems known in the state of the art, and taking into account that BPPV is a regular syndrome that affects patients in a chronic way, and that therefore needs to go to the specialist to perform the corresponding maneuvers; It is understood that it is necessary to have a system such as the one proposed in the present invention, which improves flexibility, is portable and autonomous, and which allows this disorder to be treated in health centers by medical personnel not specialized in vestibular disorders to carry out the maneuvers.

This advantage, which cannot be obtained with the systems known to the applicant, is the use and the results are simple and intuitive to handle, since it does not require computers. or additional software or specialized technical management personnel. This is precisely what allows it to be used in the places where vertigo patients first go: to their Primary Care doctor or to the Emergency Department where, if the test is positive, the request for complementary tests (analytical, Rx, TA, etc. that in some cases are requested) with the consequent savings, as well as unnecessary referrals to specialists (ENT, neurologists, or rehabilitators) and, therefore, which supposes an optimization of the medical resources of the health system.

Description of the invention

Benign Paroxysmal Positional Vertigo (BPPV) is a disorder caused by the displacement of otoconial crystals (Ca carbonate crystals normally included in the saccule and utricle) within the semicircular canals of the inner ear. These displaced crystals produce a vestibular syndrome of short duration, usually less than 1 minute.

This syndrome is characterized by a nystagmus (rhythmic movement of the eyes) that is triggered by abnormal stimulation of one of the semicircular canals caused by displaced otoconia.

Patients with BPPV present a group of free otoconia in the affected duct. When the diagnostic test is performed, the otoconia shift according to severity, causing an erroneous detection of the position of the head by the inner ear, resulting in nystagmus.

There are different types of conditions depending on whether the involved semicircular canal is the anterior, the posterior or the horizontal, and each of them is associated with a series of maneuvers that are carried out on the body and head of the patient for diagnosis and treatment. In this sense: - For the anterior canal, the commonly performed maneuver is the Yacovino, which consists of first moving the patient to the position of cephalic hyperextension; after 30 seconds (or after the nystagmus has ceased), the head is flexed rapidly until the chin touches the chest, wait 30 seconds (or the nystagmus has ceased) and the patient is raised;

- For the posterior canal, the test to be performed is the Dix-Hallpike test; with the patient sitting on the table, the head is turned 45 degrees to the side to be explored and Next, the patient is laid down on the table, preferably placing the head 15-20 degrees below the horizontal; With this, the explored posterior canal is mobilized and, in the case of BPPV, a nystagmus occurs with an upper vertical component and a counterclockwise torsional component.

Also, for the posterior canal, the Epley maneuver is used, it consists of, with the patient sitting on a table, with the head facing forward, the head is turned approximately 45 degrees towards the affected side. Maintaining this position of the head with respect to the trunk, the patient is laid down in such a way that the head is approximately 20 degrees below the horizontal; This position is maintained until the nystagmus disappears, or at least 30 seconds. The head is then turned 90 degrees to the left with respect to the longitudinal axis of the body and this position is maintained until the nystagmus ceases (if it occurs) or at least 30 seconds. The head and trunk are then turned, en bloc, another 90 degrees to the left, so that the head is rotated 135 degrees to the left with respect to the supine position.

- For the horizontal canal, the most common diagnostic maneuvers are the Pagnini-McClure or head rotation maneuvers. It is performed with the patient on the stretcher and, ideally, with the head flexed 30 degrees so that the plane of the two horizontal canals is arranged vertically. From the starting position, the head is turned about 90 degrees to each side, and it is highly recommended to go through the central position between one movement and another. Depending on the nystagmus observed, the treatment indicated in the following table will differ:

For the treatment of the posterior arm, the Gufoni maneuver is used; Starting from the subject in a sitting position on the edge of the table, he lies down on the healthy side. After the nystagmus disappears (or after 60-90 seconds) the head is turned 45 degrees to the side healthy (nose towards the table). After the nystagmus ceases or after 60-90 seconds, the patient is incorporated.

For the anterior arm the Apiani maneuver is used; Starting from the subject in a sitting position on the edge of the table, he is laid down on the affected side. After the nystagmus disappears (or after 60-90 seconds) the head is turned 45 degrees to the opposite side (the nose upwards). After the nystagmus disappears, the patient is incorporated.

As described, the diagnostic and treatment maneuvers consist of movements and turns of the torso and / or head of the patient at certain spatial angles and with a waiting time. Although they are simple maneuvers to execute, the personnel in charge of carrying them out face a double problem: on the one hand, the sequence of carrying out the maneuvers and, on the other, the ability to properly orient the patient's torso and head according to the maneuver that must be executed.

In order to solve this problem, the present invention aims to develop a portable and autonomous system, without the need for cables or connection to any other device or plug, with which it can be used in clinics or non-specialized health centers. in vestibular disorders, which entails superior agility in the treatment of this chronic disease.

In order to make the indications of the maneuvers to be performed coincide with the natural movements that the doctor has to make to the patient to execute them, and therefore to be highly intuitive and not an invasive system for the patient, the system has been integrated in a helmet that is covered by a multi-colored illuminable surface and capable of generating motion sequences. In this way, the reference systems of the helmet and the patient coincide and the gestures that must be carried out to execute the maneuvers are completely natural and can be carried out by anyone who knows what maneuvers to carry out.

As has been commented in the state of the art, other solutions based on systems such as glasses or other means fixed to the head are known, but the fact that the present invention is based on a system in the form of a helmet instead of other elements that they are not solidary to the head like glasses, is motivated by the need to integrate all the components in the same object and that these are really solidary, which with any of the known systems is not possible; allows you to manage the angles and speeds of the head and body, perform the necessary calculations and indicate the maneuvers to be performed for diagnosis and / or vestibular treatment in an intuitive way. Are characteristics allow the system to be portable, compact and, unlike known solutions, the present invention does not have cables, which not only makes it different, but also improves the conditions of use compared to those known systems and, for example , makes it ideal for use outside hospitals.

In this sense, being known other existing systems on the market based on glasses or similar elements whose objective is to recognize nystagmus, which is not the objective of the instrument presented in this document, the helmet on which the system is based. The present invention is a tool to perform chronic otolith replacement maneuvers, most of the time, to patients who have previously been diagnosed with this disease in a hospital or specialized center, with which the determination of nystagmus. In addition, as has already been commented above, the objective of this tool is to help carry out this chronic treatment, and the new configuration of the system allows it to also be carried out in non-specialized centers such as health centers or similar, mitigating saturation of patients in the consultations of hospitals specialized in this type of vestibular disorders.

Taking into account all these aspects, the system object of the present invention is based on a helmet where the following four components are integrated:

- an orientation module, a module that is responsible for measuring the position, velocity and angular acceleration of the patient's head and trunk with respect to a reference system,

- a representation module, a module that indicates in a visual sequential and intuitive way to the personnel the progress of the maneuver they are executing and when their final position has been reached,

- a calculation module, which is a microcontroller that performs the interpretation of the measurements, manages those that have to be carried out by the staff and calculates the intuitive representation mode for the sanitary and

- a communication and power supply module, a module that provides the power system (portable and rechargeable), and also serves as a wireless interface with healthcare personnel for entering orders and confirming the maneuvers to be carried out.

Going into greater detail, the orientation module is jointly installed in the helmet and, therefore, is fully joint with the patient's head. This module measures the angular displacements of the head when executing the maneuvers, and where these Offsets are angular and defined as yaw, pitch, and roll (Figure 2). This module is composed of a motion and position sensor that includes at least one accelerometer with gyroscope and magnetometer, which gives it nine degrees of freedom, and with a processing unit and a master-slave I2C communication capable of processing and transmitting to the calculation module the following parameters:

- Absolute orientation, using Euler vectors

- Absolute Orientation, through Quaternions.

- Angular velocity of the 3 axes

- Angular Acceleration of the 3 axes

- Magnetic field intensity vector

- Linear acceleration vector

- Vector force of gravity

- Room temperature

In one embodiment of the invention, the motion and position sensor is of the type commercially known as BNO055.

To measure the angular position of an object in three-dimensional space, Euler angles are used. These angles provide an intuitive way to represent the orientation of an object in three dimensions using a combination of three rotations about its different axes. This is what is called the "natural" way of understanding the turns with respect to the three axes of our three-dimensional reference system.

However, this "natural" representation of turns and orientations involves trigonometric expressions that have various problems to calculate, such as that the singular points that occur every time the 90 ° is exceeded cause an indeterminacy (singular points) in the calculation. which ends in a mathematical error; and where it is not possible to represent two or more consecutive rotations using the Euler representation since it does not satisfy the law of vector addition, which shows that finite rotations are not really vectors and, in the case of the maneuvers that concern us Almost all movements to perform repositioning maneuvers require turns combined in sequence.

For these reasons, a sensor has been used in the system object of the present invention, which cannot be installed in devices such as glasses or the like as it is not attached to the head and due to the very structure of said solutions, which allows the orientation to be reflected. absolute by means of the Hamiltonian representation with the quaternions that does not have these limitations, since it uses the product of quaternions to represent the combination of two or more individual turns and since it does not have trigonometric components, singular points are avoided. However, as they are representations in the plane of complex numbers, they are not intuitive angles and therefore require post-processing to represent the maneuvers to be executed. This post-processing requires computer tools such as programming libraries or specialized programs (such as MatLAB or similar) to be able to carry out this conversion, which implies computers connected to the maneuver measurement system and, consequently, the compactness and portability of the system is lost. here presented.

In addition, the vast majority of orientation sensors measure angles by integrating acceleration vectors on their axes, which means that, in the case of horizontal rotation on the z axis (vertical gravity), the system is not capable of detect it, since the gravity vector does not vary when that turn is made and, therefore, the acceleration is zero.

The orientation module is preferably located in the central rear part of the helmet, and preferably, communication with the calculation module or microcontroller is through the I2C protocol, so it only requires two communication cables and another two for the power supply, all of them integrated into the hull structure.

On the other hand, the calculation module, the module in charge of managing and calculating the maneuvers, includes a microcontroller that interprets the measurements received from the orientation module, and manages those that the personnel have to perform and calculates the mode of operation. Intuitive representation for the toilet. In this sense, and in a possible embodiment of the invention, a microcontroller of the ESP32 series is used which performs the processes of reading and interpreting the measurements, calculating the movements necessary to reach the angles foreseen in the maneuvers to be carried out. They must be executed and their conversion back to Euler angles so that they are easily indicative and interpretable by the personnel who will execute the maneuvers. In addition, this module includes low energy wireless communication protocols via Wi-Fi and Bluetooth.

The microcontroller manages several communication ports, and an I2C port is used for communication with the motion and position sensor and a universal asynchronous transceiver module (UART), which is an element that controls serial ports and devices and that It is integrated into a microcontroller motherboard, for tasks of programming / firmware update through a microUSB port that also serves to recharge the battery power that powers the entire system.

In addition to these ports, the microcontroller has several pins configurable as input or output that will be used to initialize the system and to activate the signals that provide the power-on sequence and the color of a matrix of LEDs that serves as an indication of the operations to be carried out. perform.

As for the representation module, it is the module that indicates the movements for the execution of the maneuvers.

For the indication of the maneuvers, a matrix of multi-color addressable led lights has been used integrated into the entire surface of the helmet, covering the entire surface of the helmet, in such a way that they allow to represent the turns of the maneuvers to be carried out by means of very progressive ignition sequences. intuitive for anyone. This matrix, which allows to cover a surface that is jointly fixed to the entire head of the user, which allows, unlike any other known solution, precisely to be able to develop sequences that allow any doctor, without the need to be highly specialized in treatment vestibular replacement techniques, follow the necessary sequence of movement. In the figures that can be seen later, the entire surface of the helmet is covered with multicolored led lights.

In one embodiment of said sequence, where the colors are a possible example of an embodiment:

- a red color of the lights indicates to the personnel performing the maneuvers that the movement to be carried out is of the head on the Z axis (horizontal rotation of the head on its natural point of rotation). The lights turn on sequentially (one after the other) in the direction of the maneuver and as it moves, in this case the patient's head, the lights remain fixed indicating the part of the turn that has been completed. When the angle determined by the maneuver to be performed is reached, the entire helmet lights up for 5 seconds intermittently to indicate the success of said turn.

- the blue color of the lights indicates that the movement to be carried out is the patient's trunk (turning on the base of the commune, the head and trunk acting as a single object). The lights turn on sequentially (one after the other) in the direction of the maneuver and as the patient moves, in this case the entire trunk and head of the patient, the lights remain fixed indicating the part of the turn that has been completed. When the angle determined by the maneuver to be performed is reached, the entire helmet flashes green for 5 seconds to indicate the success of said turn. Subsequently, in Figure 6 represents the sequence of illumination of the helmet in two maneuvers where the head or the entire trunk is moved.

In any case, and given that the maneuvers can be combined (more than one turn or movement one after the other), the helmet proceeds to indicate the following sequence to be carried out after the entire helmet flashes green. If the indicated turn is the last of the entire series of the maneuver, the helmet remains lit green continuously.

The protocol to control the matrix of LEDs is preferably the one commercially known as WS2812B, which comprises a single cable integrated into the structure of the helmet for data and allows a cascade system. It is a unidirectional system, in which each led has an integrated chip that processes the input signal, amplifies it and sends it to the next led. In this way it is possible to control the individual lighting and color of each led and form intuitive sequences of movement.

The LED matrix is activated through an output pin of the microcontroller.

Finally, regarding the communication and power supply module, it is the part in charge of programming, communication, load and power.

To make the measurement and indication module as flexible as possible and portable, any type of cable has been dispensed with, so that the power for operation comes from a power supply built into the helmet, which is not it is possible to obtain with no solution to the known date. In a preferred embodiment of the invention, the power supply is a 2500 mAh Li-ion battery, rechargeable through a microUSB port that in turn serves as a firmware update and programming port for revisions, debugging or expansion of the firmware. functions.

In order to simplify and enhance all the new functionalities of the invention, the helmet allows the introduction of the maneuvers that the helmet will have to represent and follow, using the Bluetooth communication capacity of the microcontroller. For this purpose, an interface independent of the helmet has been developed, being this supported by the mobile device that any medical staff usually carries, such as a smartphone or tablet equipped with a Bluetooth interface. This communication has a double objective, on the one hand, the user communicates to the microcontroller wirelessly the maneuvers that have to be carried out. execute, so that he determines the necessary turns to indicate and follow. On the other hand, the microcontroller sends the confirmation that the maneuver is well carried out, although it is also indicated by the lighting in green of the entire helmet.

This means that the second objective of the present invention is to define a system that, comprising a helmet such as the one previously indicated, allows connection to external devices without the need for wiring, increasing the benefits and advantages of the invention.

The system operator has the option of stopping the execution of the program on the device at any time, using the application. In this case, the application would send another command to the microcontroller and it stops its execution, waiting for the next command.

Extending the functions of the helmet, the application also has a non-invasive diagnostic function of the disease, in this case, the indication / measurement of maneuvers by the helmet is combined with the observation by the ENT specialist of the presence of nystagmus . In case the maneuver is completed, the helmet sends the application a signal indicating that it has finished, then the application asks the user if nystagmus has been detected in the patient. Here there are several options: whether the nystagmus is geotropic, ageotropic or there is no nystagmus, the application saves this information in a variable that can then be used for chronic patient follow-up where appropriate.

As an example of the operation of the application developed below, the left horizontal channel diagnosis maneuver is shown, waiting for the user to be ready to start. Once the diagnosis of this channel has been made, the medical personnel are again questioned about the existence of nystagmus, with the same options as before, saving the answer in a new variable, after which different possibilities arise: that nystagmus has been detected in one channel, that nystagmus has been detected in both channels, or that nystagmus has not been detected.

In the first case, we proceed directly to indicate the liberation maneuver for said channel according to the nystagmus that the patient presents. If there is nystagmus in more than one channel, the user will be asked in which sense it is more intense, since this will be the affected channel and it will be treated. If there is no nystagmus in the patient, proceed to the next diagnosis.

Next, we proceed with the diagnosis of the anterior canal, and as before, it is indicated whether or not there is nystagmus and, if so, we proceed to its treatment; if not, the posterior canal is diagnosed and, again, if there is nystagmus, it is treated, otherwise, the patient does not have BPPV.

Finally, a menu function has been implemented that allows any treatment or diagnosis that the patient requires at a certain time to be carried out.

It should be noted that, throughout the description and the claims, the term "comprises" and its variants are not intended to exclude other technical characteristics or additional elements.

Figure 1 schematically represents the interaction of medical personnel with the patient using the helmet as an indicator of the type of maneuver to be performed and its progress. In the case represented, the helmet is indicating to the personnel executing the maneuver that they have to turn the patient's head 30 degrees by sequentially turning on the helmet lights in that direction. When the degrees corresponding to the execution of the maneuver are reached, the lights turn green to indicate that the correct orientation has been reached.
