DESCRIPTION

Portable device for monitoring physiological signals and associated procedure

OBJECT OF THE INVENTION

The purpose of the present patent application is a portable device for monitoring physiological signals of a patient that comprises control means in connection with at least one data input port of at least one physiological signal of the patient, according to claim 1, the monitoring system in which it is integrated, according to claim 9, and the associated procedure for monitoring physiological signals, according to claim 11, additionally incorporating notable innovations and advantages.

BACKGROUND OF THE INVENTION

One line of research and technological advance in medicine is the improvement in diagnosis and the search for strategies to reduce stress in people. Stress is a state of mental fatigue caused by the demand for performance much higher than normal, which causes physical and mental disorders. The appearance of stress during the development of activities of daily living such as work, study or rest, lead to changes in the mood of individuals that affect their personal and professional performance.

Individualized knowledge regarding the degree of stress to which one is subjected is extremely useful when determining the execution of activities that pose a risk to the person themselves or to others. As an illustrative example, cite patients who have suffered a stroke, having to perform assisted rehabilitation tasks with a robot, and are not able to express the sensations that said interaction produces. If the sensation produced is stress, the patient will not be able to successfully perform the rehabilitation. To solve this problem, biomedical devices began to be used capable of reading and recording physiological signals so that a specialist would be able to determine if a subject is suffering from stress at a given moment.

Mention that a biomedical device is considered to be an operational and functional medical device that brings together electrical, electronic and hydraulic and/or hybrid systems and subsystems, which for their use require an energy source, including computer programs that intervene in their proper functioning. Currently there are inventions and developments on the market that allow determining the degree of stress or analyzing and monitoring certain physiological signals, without being constituted as biomedical devices and being methods or devices for reading and recording only.

Cite in this regard, by way of illustration, patent ES2715386, in which a sensor device for measuring physiological electrical signals is shown, comprising: a textile electrode, in which the sensing part has an electrically conductive sensing surface area intended to come into contact with a person's skin; a first electrical connection electrically connected to a device for acquiring and processing the physiological signals detected by the textile electrode, and an electrical connection that electrically joins the textile electrode to the electrical connector, wherein the electrode has a three-dimensional textile structure made by weaving warp threads and weft threads. The detection part comprises a textile upper layer whose upper surface extends over the surface detection area and a textile lower layer, arranged below the upper layer and joined to the latter along a perimeter bond line so as to create a cavity defined by the bond line and to define a region outside the bond line comprising the peripheral textile portion. The cavity is filled with a filling material so that the sensing textile part protrudes in height with respect to the peripheral textile part. Said sensor device cannot, however, be considered a biomedical device that offers a reading of the results, nor is it specifically applied to the measurement of stress.

It is also known, from the state of the art, what is described in international patent WO2009136306A1, in which a method for determining a physiological condition of a person is described, which comprises sampling a plurality of heartbeats of the person, extracting a series of cardiac intervals from heartbeat samples and provide a two-dimensional representation of subsequent beats. Two subsequent intervals form an entry in the two-dimensional representation, where the method further comprises the steps of determining a centroid, an average radius, and an average rotation frequency for the plurality of entries in the two-dimensional representation. The method allows determining a plurality of distances between the radius and each of the inputs in the two-dimensional representation, and determine the physiological condition of the person using the radio in combination with the plurality of distances. An advantage derived from this solution is that the time necessary to determine the coherent state of the person is minimized while at the same time it is possible to quickly detect a change of state since each of the inputs is directly related to the radius of the ellipse.

It is generally observed that devices already known in this field of technology do not have the objective functionalities of a device for biomedical purposes. In some cases they allow heart rate to be recorded, but without the possibility of exporting the data, only being able to view it in real time. Thus, and in view of all the above, the need is still appreciated to find an electronic device with a low manufacturing cost, with easy integration between the component parts, for reading, recording, exporting and storing physiological signals in the cloud as data files.

DESCRIPTION OF A PREFERRED EMBODIMENT

In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed, comprising the parts and elements indicated and described in detail below.

In Figure 1 you can see a complete perspective breakdown of the different elements that make up the portable monitoring device of the present invention. Specifically, the arrangement of the upper casing (2) can be seen, closed at the bottom by a lower cover (21), which, in a preferred embodiment, has a handle (22) to house a tape (23) in order to be carried. by one patient (1). Said lower cover (21) can therefore have an ergonomic function to be adjusted to the wrist of the user or patient (1) by means of a strap (23), which is what makes it a portable device.

An intermediate cover (24) can also be seen, which divides the internal compartment of the casing (2) into an upper part where a touch screen (34) is located, and a lower part, where various electronic components are housed, such as means of control. control (31), wireless connectivity means (33), storage means (36) and capture means (4), which can be, in a particular embodiment, either ECG capture means (41) or capture means GSR (42), or both. Said capture means (4) are usually electronic modules programmable in Arduino with open source.

Additionally, there are holes in the housing (2) intended for an input port (32), which, depending on the capture means (4) included, can be either an ECG input port (32a), or a GSR input port (32b), or have both available. On the opposite side it has a hole to house a switch (32c) for the alternative recording of each of the two physiological ECG or GSR signals.

Note that, in said Figure 1, an embodiment of the portable monitoring device is specifically represented in which the housing (2) would preferably be 3D printed with biomedical materials, with the HMI (human machine interface) touch screen being in contact with a microcontroller. ESP8266 and CH340 chip. Mention that, as seen in Figure 2, the lower cover (21) can be replaced by another without handles (22), depending on the final configuration that you want to give to the device.

In Figure 2 you can see a partial exploded perspective view of several elements that make up the portable monitoring device, in another embodiment. The casing (2) can be seen closed below with a lower cover (21), this time without handles (22), that is, suitable for placing the device on a horizontal surface, and the corresponding gaps for the entry port(s). (32), which may be an ECG input port (32a), or a GSR input port (32b), or both. You can also see the space for the power supply means (35), which preferably has a port for connection via micro-USB to an external 5V power source or a computer. And on the opposite side is the hole for the switch (32c), with the switch (32c) itself also being represented, as a two-position switch for choosing the physiological signal to be recorded, ECG or GSR.

In view of the above, and in a preferred embodiment of the portable monitoring device of the present invention, the sensors are connected to the housing (2) through of three ports, the ECG signal input port (32a) and the GSR signal input port (32b), and the external power is connected to the device via the micro-USB port for powering the touch screen ( 34) as an HMI, the microcontroller and the ECG and GSR signal reading modules.

The microcontroller or control means (31) is powered at 5V, which in turn powers the ECG signal reading module, or ECG capture means (41), at 3.3V to which it is connected with an input/output ( analog I/O. The same happens with the GSR signal reading module, or GSR capture means (42), which supplies 3.3V and connects to an analog I/O. Since the I/O port is the same for both signals, we use a toggle switch (32c) on which the subject, either the patient (1) or the healthcare assistant, acts to choose which signal to process.

The HMI touch screen (34) is connected to the microcontroller through the RX and TX serial ports, which in turn supplies it with 5V for its operation. All grounds are connected to the ground port (GND) of the microcontroller. The ECG and GSR signal reading modules as well as the microcontroller are screwed to the intermediate cover (24) that acts as a separator between them and the HMI touch screen (34). In turn, the HMI touch screen (34) will be screwed to the housing (2) as seen in figure 1.

On the other hand, it should be mentioned that the lower cover (21) of the housing (2) is attached to said housing (2) under pressure, with a difference in perimeter dimensions of tenths of a millimeter, which ensures a totally reliable pressure coupling. For its part, the switch (32c) is screwed to the housing (2).

Once the device is assembled and all the connections have been arranged, it will be turned on to measure heart rate and skin sweating. Power on can be done with any external 5V power supply via micro-USB. The device starts with a welcome home screen, to ask the user, optionally the patient himself (1), what signal to record. Before choosing GSR or ECG, the user must place the sensors: the GSR on the index and middle fingers, and the ECG with electrodes in lead D1, and then take one of the two options by selecting on the touch screen (34). The touch event is recorded and the signal graph is displayed on the screen in real time, as well as the maximum, minimum and average values in one-second intervals. By activating the virtual Wifi button, the touch event is recorded to Automatically start sending data to the web server where it is stored. Once registration is finished, the power to the device is disconnected.

In Figure 3 you can see a plan view of the portable monitoring device, and specifically the components of the casing (2) and the touch screen (34). It can be seen from the 3D printed casing (2) with hollow cylinders where threaded knurled females are housed to screw the touch screen (34) into its corresponding hole.

In Figure 4 you can see a view of the portable monitoring device in the position of use on a patient (1), in order to measure a physiological signal (11). The fastening of the housing (2) by means of a tape (23) and the ease of access of the patient (2) or the medical user to the touch screen (34) can be seen.

In Figure 5 you can see an illustrative view of the wireless connectivity means (33) with the cloud (5).

Emphasize the fact that the portable monitoring device is manufactured by 3D printing with biomedical materials that meet the biocompatibility requirements of USP Class VI or ISO 10993-1 certifications, which guarantees that it is biocompatible for up to 30 days in contact with the human body. In addition, the device makes use of low-cost electronics, optionally AD8232 boards for ECG, LM324 for GSR and an ESP8266 board for the microcontroller and Wifi connectivity with the online database, having a Nextion 531619133525-4 TFT screen (a HMI mode: Human Machine Interface) for the visualization of physiological signals, results and consultation of the history of the patient (1) or subject, which makes it an operational and functional biomedical device suitable for extensive use among the population without the need of specific knowledge in engineering, medicine or health.

The functionalities of the portable monitoring device place it among those offered by devices categorized as biomedical, with BT and Wifi connectivity, ECG and GSR measurement, cloud storage (5) and the possibility of exporting in.txt and.csv formats. . Furthermore, as it has a 2.4-inch touch screen (34) and can be worn on the wrist with a strap or ribbon (23), it has features close to a smartwatch, maintaining the ergonomics and manufacturing materials that They comply with biomedical standards, at a lower final cost than their competing devices. Additionally, it should be mentioned that the invention falls within the sector of portable biomedical devices, more specifically those manufactured using additive manufacturing technologies with biocompatible materials that make use of low-cost electronics for reading and sending data through Wi-Fi connectivity. . Specifically, this device allows reading and recording the heart rate and skin sweating, to determine the degree of stress of a patient (1) during the development of daily tasks.

More particularly, as seen in Figures 1 and 2, the portable device for monitoring physiological signals (11) of a patient (1) comprises control means (31) in connection with at least one input port ( 32) of the data of at least one physiological signal (11) of the patient (1), wireless connectivity means (33), a touch screen (34), and a housing housing (2) with a lower cover (21) removable.

On the other hand, as seen in Figure 2, the portable monitoring device comprises electrical power means (35) through a micro-USB port, this being, preferably, an external 5V power supply. .

It should be noted that, as seen in Figure 1, the portable monitoring device comprises a plurality of input ports (32) for the data of a plurality of physiological signals (11) of the patient (1), and a switch (32c) for selecting from said plurality of input ports (32).

Additionally, as seen in Figure 1, the portable monitoring device comprises storage means (36) for the received data.

According to another aspect of the invention, as seen in Figure 1, the lower cover (21) comprises at least one handle (22) configured to insert a fixing tape (23).

Alternatively, as seen in Figure 2, the lower cover (21) is smooth.

Preferably, as seen in Figures 1, 2 and 3, the casing (2) and/or lower cover (21) are manufactured using a 3D printing procedure.

More specifically, as seen in Figures 1, 2 and 3, the casing (2) and/or lower cover (21) are manufactured with at least one biocompatible material.

According to a preferred embodiment of the invention, as seen in Figure 1, the monitoring system comprises a portable device with means for capturing the physiological signal (11) of the heart pulse.

Additionally, as seen in Figure 1, the monitoring system comprises means for capturing the physiological signal (11) of the galvanic response of the skin (4).

It is also the object of the present invention, as seen in Figure 4, a procedure for monitoring physiological signals (11) of a patient (1), which includes the steps of i) connection of capture means (4 ) of a physiological signal (11) to the patient (1); ii) selection on a touch screen (34) of the physiological signal (11) measured by the capture means (4); iii) display on the touch screen (34) of historical data values of the selected physiological signal (11), available on storage media (36); iv) activation by the touch screen (34) of data transmission to the cloud (5) through wireless connectivity means (33); v) stopping said data transmission to the cloud (5) by the touch screen (34).

Specify that connectivity to a Wi-Fi network is done from the device's own interface, having to write the name of the network to which you want to connect, the connection parameters and the access credentials. Every time connectivity is activated, the device will try to connect to the last accessed network by default. If you cannot establish a connection, a menu appears to enter the parameters of a new network to connect to. And once the data collection is finished, the subject disconnects the auxiliary power supply to turn off the device and thus end the process. Every time the device is turned on, it automatically loads all the information stored by default. If you want to delete part of the information, simply remove the internal micro-USB memory and manually delete those files that you want to delete.

More specifically, as seen in Figure 4, the selection of the physiological signal (11) measured by the capture means (4) is between the cardiac pulse and the galvanic response of the skin.

Thus, once the subject connects the sensors and the power supply, the touch screen (34) displays a menu to choose the ECG or GSR measurement. Once the desired option has been chosen, the device displays, through the touch screen (34), the maximum, average and minimum values of the recorded values, as well as a graph with time on the horizontal axis and the corresponding unit of measurement. to each signal on the vertical axis. It also shows the button to start/stop the transmission of the data record to the cloud (5) via Wifi connectivity.

Additionally, as seen in Figure 5, the monitoring procedure includes the recording stage in the storage means (36) of the data measured by the capture means (4), being assigned to the patient's history (1 ) monitored. Thus, once the data collection is completed, the subject stops reading and recording from the device's own interface, with everything up to that point having been transmitted to a web server if the Wi-Fi digital switch has been turned on. The device will ask if you want to save the record to the internal storage unit, thus creating a profile for each patient subject (1) that can be consulted without having to connect to the web server records.

More specifically, as seen in Figure 5, the recording on the storage media (36) of the measured data is in '.txt' or '.csv' format. Thus, the stored data can be exported in '.txt' or '.csv' format for subsequent mathematical or statistical treatment, which is a strong point of the technology given that the rest of the devices available on the market do not offer this functionality. . Therefore, the device of the invention has control means (31) or Arduino-based microcontroller with Wifi connectivity for sending the data recorded by the ECG and GSR reading modules to a cloud-based web server (5). for storage in.txt and.csv formats.
