Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a brain health monitoring headband. Background Art

[0002] Transcranial Doppler (TCD) is a non-invasive cerebrovascular disease examination method that uses the ultrasonic Doppler effect to detect the hemodynamics and physiological parameters of the main intracranial arteries. It uses low-frequency pulsed ultrasound to penetrate the thinner temporal part of the skull to obtain blood flow signals from intracranial blood vessels. It can obtain parameters such as blood flow velocity, blood flow direction, elasticity and compliance of vascular walls, vascular stenosis, and peripheral resistance of cerebral vessels in intracranial and extracranial blood vessels to reflect the functional status of cerebrovascular vessels.

[0003] Near Infrared (NIR) technology is a non-invasive brain imaging technology that uses the brain's neural biological tissue to have good penetration and scattering properties of 650-950nm near-infrared light. It measures brain functional activities in brain tissue through near-infrared light as the concentration of absorption chromophores such as oxyhemoglobin and deoxyhemoglobin changes, and observes tissue physiological functional activities based on the neurovascular coupling mechanism. It has advantages in evaluating cerebral blood oxygen / emotional psychology / cognition, etc. At the same time, it can be combined with transcranial Doppler technology to evaluate and monitor the degree of cerebral vascular sclerosis and changes in intracranial pressure.

[0004] At present, brain function assessment relies on clinicians and large equipment. A single visit to the hospital cannot provide continuous monitoring. Therefore, there is a lack of portable, daily equipment that covers a variety of brain health indicators such as cerebral vascular sclerosis, emotional psychology, cognition, intracranial pressure, cerebral blood oxygen, and cerebral blood flow. In addition, when conducting an ultrasound examination, medical staff need to hold the ultrasound probe close to the patient's head for a long time. During this process, if the medical staff's hands shake slightly or the patient's head moves slightly, causing the ultrasound probe's detection point to shift, it will cause deviations in the measurement results.

[0005] In the prior art, a patent document with the announcement number CN207412182U proposes a fixing frame for an ultrasound probe of a transcranial Doppler monitor. The transcranial Doppler monitor includes two ultrasound probes, and the fixing frame includes: a clamping member, which includes two ends in relative positions and an elastic body connecting the two ends, and the elastic body drives the two ends to provide a clamping force to the inside respectively; and two covers, the inner sides of which have fitting surfaces for fitting with the detection windows on both sides of the human head, respectively. The two covers are respectively fixed on the two ends of the clamping member, and the two ultrasound probes are respectively arranged on the two covers, and the detection surfaces of the ultrasound probes protrude from the fitting surfaces. Although the fixing frame can make the ultrasound probe stably fit the monitoring position, eliminate the displacement of the ultrasound probe and the detection window caused by the shaking of the ultrasound probe held by the medical staff or the movement of the patient's head, improve the stability of the collected blood flow signal, and can be used in daily life, but only the transcranial Doppler probe is used for monitoring, and the monitoring of other brain health signals of the patient is lacking, so that the monitoring results that can be obtained in the end are relatively single, and it is difficult to form a multi-angle and comprehensive brain health assessment of the patient.

[0006] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventor studied a large number of documents and patents when making the present utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present utility model does not have the characteristics of these prior arts. On the contrary, the present utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0007] In response to the shortcomings of the prior art, the present application proposes a brain health monitoring headband, in particular, a brain health monitoring headband with near-infrared light technology and transcranial Doppler technology, aiming to solve one or more technical problems in the prior art.

[0008] In the existing technology, brain function assessment relies on clinicians and large equipment, and more comprehensive brain function monitoring can only be completed in the hospital. This is very cumbersome for patients who need long-term brain function monitoring. In addition, when patients undergo ultrasound examinations, medical staff are required to hold the ultrasound probe close to the patient's head for a long time. During this process, if the medical staff's hands or the patient's head are slightly offset, the detection point of the ultrasound probe will change, which will ultimately lead to deviations in the measurement results.

[0009] In order to achieve continuous and stable data detection of the detection points, the prior art has already appeared a technical solution that sets the detection device to be wearable on the head. For example, the patent document with publication number CN114366089A discloses a near-infrared spectroscopy device that can be worn on the head, including a head ring body, a restraint belt arranged on the head ring body, and a near-infrared control system arranged in the head ring body, the two ends of the restraint belt are respectively fixed to the two ends of the head ring body, and the head ring body can be worn on the frontal lobe area of ​​the head. This technical solution emits near-infrared light to the frontal lobe area of ​​the head through a near-infrared lamp group, and cooperates with infrared sensors to use near-infrared spectroscopy technology to estimate blood volume and oxygenation through light propagation, and can measure changes in oxygen and deoxyhemoglobin concentrations in the area near the cortical surface. However, this technical solution only provides a fixed head ring structure for carrying the near-infrared detection equipment. On the one hand, the head ring structure with such a fixed structure setting cannot adaptively adjust the detection points of the infrared detection equipment according to different patients, thereby reducing the accuracy of the detection data; on the other hand, the head ring structure in this technical solution cannot be used for both the near-infrared light technology and the transcranial Doppler technology in the health detection process. A single head-mounted ring structure setting cannot simultaneously meet the position requirements for near-infrared light technology detection and the position requirements for transcranial Doppler technology detection.

[0010] Therefore, in response to the above technical problems, the utility model proposes a brain health monitoring headband that can be used in daily life scenarios, including a skeleton component that can be worn on the user's head; a probe component arranged in the skeleton component and corresponding to the user's temporal part; and a plurality of near-infrared photocells arranged in the skeleton component and corresponding to the user's forehead. The light shielding pad is connected to the inner side of the middle part of the skeleton in a manner of surrounding all the near-infrared photocells, and at least part of the skeleton component can bend adaptively and fit the probe component and the near-infrared photocell to the user's head in the form of force fit and / or shape fit, so that the probe component and the near-infrared photocell are correctly configured at the corresponding monitoring position on the user's head.

[0011] In the prior art, there are already technical solutions that improve the accuracy and precision of near-infrared spectroscopy detection by setting a shading structure. For example, the patent document with publication number CN210644032U discloses an anti-disturbance cerebral blood oxygen analyzer based on near-infrared spectroscopy, including a light shield, a flexible fitting part for fitting the head is installed at the bottom of the light shield, and fixing belts for fixing the light shield to the head are installed on both sides of the light shield. A near-infrared light source probe, a photoelectric receiver and a photoelectric sensor are installed in the light shield, and the near-infrared light source probe, the photoelectric receiver and the photoelectric sensor are installed above the flexible fitting part, and the flexible fitting part is provided with a light-transmitting groove for allowing near-infrared light to pass through the flexible fitting part, and the near-infrared light source probe and the photoelectric receiver are both installed with an adjustment device. This technical solution detects ambient light and scattered light of the near-infrared light source through a photoelectric sensor and eliminates their influence in the overall data detected, thereby improving the accuracy of blood oxygen data. However, the near-infrared light source probe structure in the technical solution is directly arranged on the closed light shield structure, and the head-mounted structure of different patients can only be adjusted through the flexible fitting part, and the near-infrared light source probe cannot be adaptively adjusted according to the specific conditions of the patient. Compared with the above-mentioned prior art, the skeleton component in the utility model can simultaneously fit the probe component and the near-infrared light electrode to the user's head in the form of force matching and / or shape matching, and a light shielding pad is arranged on the inner side of the middle part of the skeleton in a manner surrounding all the near-infrared light electrodes. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to simultaneously achieve stable near-infrared light and ultrasonic detection, and improve the accuracy of detection. Specifically, the utility model completes two different types of measurements by arranging the near-infrared light electrode and the probe component on the skeleton component, so that the brain function parameters finally obtained are more comprehensive. The setting of the skeleton component enables the near-infrared light electrode and the probe component to be fixed in the corresponding position of the user's head in a relatively stable manner, avoiding the deviation of the measurement result caused by the shaking of the user's head. At the same time, the skeleton component can also replace the handheld device for measurement, freeing both hands and improving the monitoring efficiency. In addition, the shading pad surrounds all the near-infrared photocells, which can minimize the impact of external light sources on the measurement of the near-infrared photocells.

[0012] According to a preferred embodiment, the skeleton assembly includes a skeleton middle portion and a skeleton end portion, and a plurality of near-infrared photocells are arranged on the inner side of the skeleton middle portion along the extension direction of the skeleton middle portion. Compared with the above-mentioned prior art, the infrared photocell structure in the utility model can be adaptively arranged according to the specific extension structure of the skeleton. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to improve the accuracy of the setting of infrared photocell detection points. Specifically, since the skeleton middle portion and the skeleton end portion correspond to the user's forehead and temporal region respectively, arranging near-infrared photocells and probe assemblies in the skeleton middle portion and the skeleton end portion can ensure an accurate monitoring range.

[0013] According to a preferred embodiment, the probe assembly includes a housing cover and a transcranial Doppler probe disposed inside the housing cover. The housing cover provides a base for the transcranial Doppler probe to be placed, and also protects the transcranial Doppler probe. In addition, at least the portion of the housing cover that fits the temporal skin of the user is made of a flexible material, which can alleviate the pressure of the probe assembly on the temporal skin of the user and improve comfort.

[0014] According to a preferred embodiment, an adjustment mechanism for adjusting the distance between the skeleton component and the user's forehead is provided on the outer side surface of the skeleton end, and the adjustment mechanism is connected to the accommodating sleeve. Compared with the above-mentioned prior art, the utility model is provided with an adjustment mechanism of an arc segment on the skeleton component. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to adjust the wearing detection position of the brain health monitoring headband according to the head parameters of different patients. Specifically, the setting of the adjustment mechanism of the utility model enables the skeleton component to be adaptively adjusted according to the head circumference of different users, so that when the position of the skeleton end is relatively determined, the relative distance between the middle part of the skeleton and the user's head can be adjusted so that it can fit better on the user's head, ensuring that the near-infrared light electrode can be attached to the user's forehead in a relatively stable manner, thereby improving the universality of the brain health monitoring headband.

[0015] According to a preferred embodiment, the ends of the skeleton can be elastically deformed to different degrees according to the head circumference of different users, so as to drive the probe assembly to fit the user's head. The material used for the ends of the skeleton is different from that used for the middle part of the skeleton, and the ends of the skeleton are made of a more elastic material. By appropriately bending the ends of the skeleton outward, the distance between the probe assemblies on it can be increased, so that the probe assemblies can fit the user's temporal position with the help of elastic force.

[0016] According to a preferred embodiment, the near-infrared light electrode is detachably connected to the first buckle mother component provided in the form of a perforation on the inner side of the middle part of the frame through the first buckle sub-component thereon, and the light-shielding pad is detachably connected to the second buckle mother component provided at the edge of the middle part of the frame through the second buckle sub-component thereon. For the near-infrared light electrode, the first buckle sub-component and the first buckle mother component occupy a small volume and have high stability. This form of fixation can reserve enough placement space for the near-infrared light electrode; and for the light-shielding pad, the detachably connected second buckle sub-component and the second buckle mother component can be used to replace the light-shielding pad to ensure that the user can always have a good monitoring experience.

[0017] According to a preferred embodiment, the adjustment mechanism includes an adjustment frame and an adjustment member, the adjustment frame is connected to the accommodating sleeve, and the adjustment member is connected to the outer side of the frame end. The setting of the adjustment mechanism enables the frame assembly to be adaptively adjusted according to the head circumference of different users to ensure that the middle part of the frame can better fit the user's head.

[0018] According to a preferred embodiment, a through hole is provided on one side of the accommodating sleeve attached to the user's head, so that the transcranial Doppler probe inside the accommodating sleeve can directly contact the skin surface of the user's temporal region.

[0019] According to a preferred embodiment, the brain health monitoring headband also includes an elastic band, the two ends of which are connected to the outer side of the housing sleeve, and the elastic band worn on the occipital part of the user and the skeleton assembly form a ring structure of the brain health monitoring headband. The elastic band plays an auxiliary fixing effect, further reducing the impact of the shaking of the user's head on the measurement results.

[0020] The beneficial technical effects of the utility model are at least as follows:

[0021] (1) The present invention makes the brain function assessment device simpler and more portable by setting it in the form of a headband, freeing the user from the dependence on clinicians and large medical equipment, so that brain function assessment can be carried out on a daily basis, which is beneficial to users who need to conduct long-term related brain function monitoring. At the same time, the examination environment in non-hospital scenarios is also conducive to objectively assessing the true condition of brain health. In addition, two monitoring devices, a near-infrared photoelectrode and a transcranial Doppler probe, are also set on the headband. The results of the joint monitoring of the two can cover more indicators, making the brain health monitoring headband more accurate and comprehensive in assessing the user's brain health.

[0022] (2) The utility model avoids the interference of external ambient light on the monitoring results of the near-infrared photoelectrode by arranging a shading pad on the periphery of the near-infrared photoelectrode, thereby improving the accuracy of the monitoring results; at the same time, the shading pad can also contact the user's forehead, alleviating the pressure of the skeleton component on the user's forehead and improving the user's experience.

[0023] (3) The skeleton assembly of the utility model is provided with two structures with different functions, namely the middle part of the skeleton and the end parts of the skeleton. The material of the middle part of the skeleton is of low elasticity and will not be deformed due to the application of external force. Therefore, it can provide a solid base for the near-infrared photoelectrode that needs to have a stable detection angle. The end parts of the skeleton on both sides of the middle part of the skeleton can bend adaptively to ensure that the transcranial Doppler probe can fit the user's temporal region well, so that the skeleton assembly can adapt to users with different head circumferences while ensuring the accuracy of measurement.

DETAILED DESCRIPTION

[0029] The utility model is described in detail below in conjunction with the accompanying drawings.

[0030] The utility model relates to a brain health monitoring headband, which can be used in daily life scenarios, such as Figure 2 As shown, the headband is detachably attached to the area above the supraorbital rim of the user's head in a force fit and / or form fit manner, and the specific wearing position is near the horizontal plane where the temporal parts on both sides of the user's head are located. Figure 1 As shown, the headband includes a frame assembly 100 that can be worn on the user's head, a probe assembly 200 located at both ends of the frame assembly 100, and an elastic band 300 connected to the probe assembly 200. Preferably, the frame assembly 100 and the probe assembly 200 form a structure similar to a headphone, wherein the middle position of the arc-shaped frame assembly 100 corresponding to the user's forehead is called the frame middle portion 110, and the parts located at both ends of the frame middle portion 110 and extending toward the user's temple are called the frame end portions 120. Preferably, as Figure 1 As shown, the middle portion 110 of the skeleton is longer than the end portions 120 of the skeleton at both ends, and occupies about 2 / 3 of the total length of the entire skeleton component 100 . Therefore, the middle portion 110 of the skeleton serves as the main body of the skeleton component 100 and plays a role in maintaining the overall shape of the skeleton component 100 .

[0031] Preferably, if Figure 1As shown, a number of near-infrared photoelectrodes 130 are arranged on the inner side of the middle part 110 of the skeleton and along the extension direction of the middle part 110 of the skeleton. The near-infrared photoelectrodes 130 measure the brain functional activity in the brain tissue by attaching to the forehead of the user and emitting near-infrared light. In addition, a light shielding pad 140 is arranged near the near-infrared photoelectrode 130 of the middle part 110 of the skeleton. Preferably, the light shielding pad 140 can be made of black silicone material and connected to the inner side of the middle part 110 of the skeleton in a manner of surrounding all the near-infrared photoelectrodes 130. The "surrounding" here can refer to the light shielding pad 140 surrounding the near-infrared photoelectrodes 130 one by one, or it can refer to the light shielding pad 140 surrounding all the near-infrared photoelectrodes 130 as a whole. The light shielding pad 140 can not only alleviate the pressure of the skeleton assembly 100 on the forehead of the user, but also reduce the impact of the external light source entering the detection area of ​​the near-infrared photoelectrode 130 on the final near-infrared detection result.

[0032] Preferably, since the middle part 110 of the skeleton needs to maintain the overall shape of the skeleton assembly 100, it needs to have a relatively hard texture. In addition, due to the need for measurement accuracy of the near-infrared photoelectrode, it cannot cause the measurement point to shift due to factors such as user shaking or external interference. Therefore, the middle part 110 of the skeleton can be made of a material with low elasticity that will not be deformed due to the application of external force, and this part is used as the base for bearing the near-infrared photoelectrode 130 to ensure that the near-infrared photoelectrode 130 can be limited to the optimal detection position. The middle part 110 of the skeleton is located at the frontal bone position above the user's nasal bone, and also has an arc that fits the user's forehead to ensure that the near-infrared photoelectrode 130 can be attached to the user's forehead as much as possible. Specifically, the middle part 110 of the skeleton fits the frontal muscle above the user's orbicularis oculi muscle and spans the frontal tubercle. The frontalis muscle is a thin human muscle located on the forehead and is quadrilateral. It is not attached to any bone. Therefore, the near-infrared photoelectrode 130 emits near-infrared light here, which can better penetrate the muscle, so that the muscle tissue reduces the interference of the observation of intracranial oxyhemoglobin, deoxyhemoglobin and other substances. The near-infrared photoelectrode 130 is widely used in the prior art, such as the near-infrared light source probe commonly used in functional near-infrared spectroscopy (fNIRS), which uses an infrared emitting diode to emit infrared light of a certain frequency, and uses an infrared receiver to receive reflected, transmitted or scattered infrared light, and converts it into an electrical signal for processing. The near-infrared photoelectrode 130 and its related components of the utility model are selected from existing technologies. For example, the prior art, such as the patent document with publication number CN113951832A, proposes a head-mounted near-infrared brain function imaging system, in which a near-infrared transmitting probe, a near-infrared receiving probe and a control component electrically connected to the probe are provided. A circuit board is provided in the probe, and a power supply integrated on the circuit board can be used to provide electrical energy. Through the control component, the probe can send and receive signals. The utility model does not involve improvements to the operating mode and signal transmission method of the near-infrared photoelectrode 130, and complies with the provisions of the Patent Law on the object of protection of utility models. Preferably, if Figure 1 As shown, the skeleton ends 120 on both sides of the skeleton middle part 110 can be made of elastic material, for example, PE (polyethylene) material can be used. Polyethylene is a common plastic material with good toughness and flexibility. The skeleton middle part 110 made of this material can be adaptively elastically deformed according to the user's head circumference, and the skeleton assembly 100 is fitted to the corresponding position of the user's head with the help of elastic force. The specific setting orientation of the skeleton end 120 relative to the user's head is: from the frontal bone through the sphenoid bone toward the temporal bone, specifically extending in the direction of the concave position between the eyebrow tip and the outer canthus of the eye about one horizontal finger behind.

[0033] Preferably, if Figure 1As shown, an adjustment mechanism 150 for adjusting the distance between the frame assembly 100 and the user's forehead is provided on the outer side of the frame end 120. The adjustment mechanism 150 includes an adjustment frame 151 that is semicircular in shape as a whole and an adjustment member 152 that is provided on the adjustment frame 151. The end of the adjustment frame 151 is connected to the accommodating sleeve 220, and the adjustment member 152 is connected to the outer side of the frame end 120. The adjustment member 152 can slide on the adjustment frame 151. When the adjustment member 152 slides along the adjustment frame 151 in a direction away from the accommodating sleeve 220, the frame end 120 connected thereto is also away from the accommodating sleeve 220, thereby increasing the distance between the frame assembly 100 and the user's forehead; conversely, when the adjustment member 152 slides along the adjustment frame 151 in a direction close to the accommodating sleeve 220, the frame end 120 connected thereto is also close to the accommodating sleeve 220, thereby reducing the distance between the frame assembly 100 and the user's forehead. The setting of the adjustment mechanism 150 enables the skeleton assembly 100 to be adaptively adjusted according to the head circumference of different users, so that when the position of the skeleton end 120 is relatively determined, the relative distance between the skeleton middle part 110 and the user's head can be adjusted so that it can fit better on the user's head, ensuring that the near-infrared light electrode 130 can be attached to the user's forehead in a relatively stable manner, thereby improving the universality of the brain health monitoring headband and the accuracy of measurement.

[0034] Preferably, if Figure 3 As shown, two different fastening components are arranged in the middle part 110 of the skeleton, and the near-infrared light electrode 130 is detachably connected with a first fastening mother component 111b arranged in a perforated form on the inner side surface of the middle part 110 of the skeleton through a first fastening sub-component 111a arranged on its surface away from the user's forehead, and the light-shielding pad 140 is detachably connected with a second fastening mother component 112b arranged at the edge position of the middle part 110 of the skeleton through a second fastening sub-component 112a thereon. For the near-infrared light electrode 130, the first buckling sub-component and the first buckling mother component occupy a small volume and have high stability. This form of fixation can reserve sufficient placement space for the near-infrared light electrode 130, and the near-infrared light electrode 130 will not be deflected due to the shaking of the user's head; and for the light-shielding pad 140, the detachable connection of the second buckling sub-component and the second buckling mother component can facilitate the user to replace the light-shielding pad 140. At the same time, the second buckling mother component is arranged at the edge of the middle part 110 of the skeleton to ensure the convenience of replacement. The light-shielding pad 140 that has been used for a certain period of time can be removed and cleaned, so that the user can complete the monitoring in a clean brain function monitoring environment.

[0035] Preferably, the shading pad 140 protrudes from the inner side of the middle part 110 of the skeleton toward the forehead of the user by a certain thickness, and the thickness is at least greater than the thickness of the part of the near-infrared light electrode 130 protruding from the inner side of the middle part 110 of the skeleton.

[0036] Preferably, the probe assembly 200 includes a housing cover 220 and a transcranial Doppler probe 210 disposed inside the housing cover 220. The housing cover 220 provides a placement space for the transcranial Doppler probe 210 and also protects the transcranial Doppler probe 210. In addition, at least one side of the housing cover 220 that contacts the user's temporal skin is made of a flexible material, which can alleviate the pressure of the probe assembly 200 on the user's temporal skin and improve comfort.

[0037] Preferably, if Figure 1 As shown, a through hole is provided on one side of the housing sleeve 220 attached to the user's head so that the working area of ​​the transcranial Doppler probe 210 inside the housing sleeve 220 can directly contact the skin surface of the user's temporal region. The transcranial Doppler probe 210 and its related components of the utility model are selected from existing technologies, such as the Doppler analyzer collar-type wearable probe used in the announcement number CN208426140U, which is arranged on a base, and an independent power supply, power switch and communication module connected to the probe are arranged in the base, so that the probe signal acquisition can be driven by an independent power supply, and the wireless transmission method of the signal does not have to be restricted by the cable connected to the transcranial Doppler host, thereby improving the convenience of use. The utility model does not involve improvements to the operating mode and signal transmission method of the transcranial Doppler probe 210, and complies with the provisions of the Patent Law on the object of protection of utility models. The transcranial Doppler probe 210 uses low-frequency pulsed ultrasound to penetrate the thinner temporal part of the skull to obtain blood flow signals from intracranial blood vessels, and can evaluate the blood flow velocity, blood flow direction, elasticity and compliance of the blood vessel wall, vascular stenosis, and peripheral resistance of cerebral blood vessels in and outside the skull. By opening a hole on one side of the housing sleeve 220 attached to the user's head, the obstruction between the transcranial Doppler probe 210 and the user's head is reduced, so that the monitoring information obtained is more accurate. Preferably, as Figure 1 As shown, the two ends of the elastic band 300 are connected to the outer side of the housing sleeve 220, and the elastic band 300 worn on the occipital part of the user forms a ring structure of the brain health monitoring headband with the skeleton component 100. The setting of the elastic band 300 further increases the fixing effect of the headband on the basis of fixing it with the skeleton component 100, ensuring that the brain health monitoring headband will not cause position deviation and measurement result errors due to the shaking of the user's head.

[0038] The following describes the steps for using the brain health monitoring headband of the present invention:

[0039] Reference Figure 2When the user wears the brain health monitoring headband of the present invention on the head, the user needs to first correctly attach the probe assembly 200 to the user's temporal position, and then adaptively adjust the adjustment mechanism 150 configured on the arc section of the skeleton assembly 100 according to the user's head circumference to ensure that the near-infrared photoelectrode 130 on the skeleton assembly 100 can fit tightly on the user's forehead; secondly, bind the elastic band 300 to the back of the user's head so that the headband is fixed on the user's head to complete the wearing of the headband; finally, start the near-infrared photoelectrode 130 and the transcranial Doppler probe 210 to measure various brain health indicators.
