Description

Physiological signal sensing device

The present invention relates to a sensing device, in particular to a physiological signal sensing device for mammals.

When the brain is functioning, the electrical swings produced by the activity of brain nerve cells create brain waves. When the heart is working, the ventricles periodically contract and contract to promote blood circulation and produce a detectable heart rhythm. When the whole body is functioning, the circulatory system maintains a constant body temperature in order to maintain various organs in optimal condition. The aforementioned brain waves, heart rhythm and body temperature are physiological signals that can be detected by animals and are used to observe the physiological conditions of animals.

Taking mammals as an example, their hearts beat continuously throughout their lives, allowing blood to circulate around the body, providing nutrients needed by the body and recycling metabolic waste. It can be said that a healthy heart is the basic requirement for keeping these animals living well. If the body is damaged by external physical (such as injuries) or biological (such as diseases), which directly or indirectly damages the heart, the function of the heart will be impaired. In the past when medicine was underdeveloped, once there was a heart problem, there was a high chance that the lives of these animals (including humans, livestock, pets, etc.) would be lost in a short period of time, or their body functions would be seriously damaged. It is a loss to human society. However, with the advancement of medical technology, factors that affect heart operation can be discovered through long-term monitoring of the state of the heart, and preventive treatments can be provided to avoid the occurrence of related diseases or alleviate symptoms.

As far as human heart rhythm detection is concerned, from the past, it was necessary to go to the hospital for short-term heart rhythm detection on large machines, to now it is possible to perform remote long-term heart rhythm detection at home. The advancement of technology is reflected in the innovation of heart rhythm monitoring equipment, and the lack of information. Complete external transmission technology. However, these heart rhythm monitoring devices, like traditional heart rhythm detection machines, need to install detection electrodes on the body as widely as possible. In addition to making people feel uncomfortable after long-term installation, how to effectively adhere to the skin without falling off and prevent the intrusion of sweat or moisture during bathing has always been the direction of research and development challenges for equipment manufacturers.

In order to make the description of the disclosure more detailed and complete, an illustrative description is provided below for implementation modes and specific examples of the present invention.

Please refer to FIGS. 1 and 2 . FIG. 1 is a perspective view of a physiological signal sensing device 1 according to an embodiment of the present invention. FIG. 2 is an exploded view of some components of the physiological signal sensing device 1 . The physiological signal sensing device 1 can be installed on the chest skin of mammals to monitor, record and transmit potential change signals on the skin surface due to physiological activities. The potential changes can be used with different analysis methods to obtain corresponding physiological signals, such as Heart rhythm changes and further obtain relevant medical data, such as electrocardiogram. The physiological signal sensing device 1 includes: a flexible fiber substrate 10, a base 20, a conductive circuit assembly 30, a signal processing assembly 40, an adhesive layer 50 and at least two covering layers 60. The types and functions of these technical components are described below.

The flexible fiber substrate 10 can be used to be attached to the chest skin of mammals and is a component of the riding base 20 , the conductive circuit assembly 30 and the signal processing assembly 40 . In terms of shape, the flexible fiber base material 10 has a main plane 11 , an extension section 12 connected to the main plane 11 , and a secondary plane 13 connected to the extension section 12 . In this embodiment, the top view shape of the main plane 11 is like the face of a teddy bear, the top view shape of the secondary plane 13 is like a falling water drop, and the extension section 12 is the narrow area between the two. In terms of materials, the flexible fiber base material 10 is made of a synthetic fiber material, which can be a non-woven fiber formed from the following compounds: polypropylene (PP), polyethylene (Polyethylene, PE), polystyrene ( Polystyrene (PS), polyurethane (PU), polyvinyl chloride (Polyvinyl Chloride, PVC), nylon (Nylon) or rayon (Rayon). The flexible fiber base material 10 is light and porous, has the characteristics of multi-directional diffusion of water vapor and breathability, and can also absorb water vapor to form a good conductor. An adhesive layer 50 is provided below the flexible fiber base material 10. The adhesive layer 50 can be releasably adhered to the chest skin of the mammal. The adhesive layer 50 can be made of acrylic glue, silicone glue or hot melt glue. Composition, skin-friendly properties. The adhesive layer 50 in FIG. 2 is only represented by thicker lines on the side of the flexible fiber substrate 10 . In order to have a better understanding of the structure of the flexible fiber base material 10 and the adhesive layer 50, please see Figure 3, which shows the flexible fiber base material 10, the adhesive layer 50, an upper covering layer 61 and a lower covering layer 62 along the The schematic cross-sectional view in the AA' direction in Figure 2. It should be noted that since soft The thicknesses of the flexible fiber base material 10, the adhesive layer 50, the upper covering layer 61 and the lower covering layer 62 are much shorter than their lengths. The thicknesses are enlarged in Figure 3 so that the appearance of each structure can be clearly seen visually. . The adhesive layer 50 overlaps with the flexible fiber base material 10 and the edges are aligned. Because the flexible fiber base material 10 has a densely woven structure with multiple connected pores (the pores are small spaces between fibers), the adhesive layer 50 and the flexible fiber base material 10 overlap. On the interface of the flexible fiber base material 10, the surface area formed by the adhesive layer 50 is larger than the surface area of the flexible fiber base material 10, and has the characteristics of water blocking and air permeability. The adhesive layer 50 and the adhered skin can be seen through the connected pores of the flexible fiber base material 10, so as to understand the adhesion situation and the health status of the skin (such as whether it is swollen by water).

As shown in FIG. 3 , the side of the adhesive layer 50 different from the flexible fiber base material 10 includes at least two non-connected covering layers 60 . In this embodiment, the aforementioned upper covering layer 61 and lower covering layer 62 are used for illustration. In practice, the number of covering layers is not limited to two. In terms of shape, the edges of two adjacent covering layers partially overlap and the overlapping area is not in contact with the adhesive surface. Excluding the shape of the overlapping area, the overall shape of the upper covering layer 61 and the lower covering layer 62 is essentially the same as the adhesive layer 50 (flexible fiber base). The top view shape of material 10) is the same. The aforementioned at least two covering layers are configured to be removed in stages before using the physiological signal sensing device 1, so that the adhesive layer 50 is exposed and adheres to the skin.

The base 20 is a component used to detachably combine with the signal processing assembly 40 and guide the circuit connection between the conductive circuit assembly 30 and the signal processing assembly 40 . The base 20 is fixed on the main plane 11 . The base 20 can be made of a skin-friendly plastic material with high strength, such as polycarbonate (PC). For the appearance of the base 20, please see Figures 4 and 5. FIG. 4 shows a comparison of the top view (top) and the bottom view (bottom) of the base 20 , and FIG. 5 is a perspective view of the base 20 . The central part of the base 20 is a plate-like structure, and a plurality of curved extensions 21 are formed at its edges, extending outward and upward from the plate-like structure. According to the present invention, at least three curved extensions 21 can detachably clamp a specific part of a housing 41 of the signal processing assembly 40, so that the housing 41 is combined with the base 20. If only three curved extensions 21 are used to clamp the housing 41, it complies with the three-point most stable support design. In this embodiment, since the housing 41 is a rectangular parallelepiped with rounded corners, the base 20 uses four curved extensions 21 to detachably clamp the four corners below the housing 41 respectively. An acupressure plate 22 is formed between two curved extensions 21, which is almost identical to the central plate-like structure. Vertical, for fingers to press and deform the base 20, causing the relative positions of the curved extensions 21 to change, so that the combined housing 41 can be removed from the base 20. It can be seen from the top view and the bottom view that the plate-like structure is recessed inward from both sides in the middle part. The recessed part is convenient for the user to cut in with his thumb and index finger to remove the combined housing 41 from the deformed base 20 . Many holes 23 are opened in the plate-like structure. Since the base 20 is adhered to the main plane 11 of the flexible fiber base material 10 , skin moisture will pass through the flexible fiber base material 10 and collect under the base 20 . The existence of the holes 23 allows the water vapor on the skin surface to evaporate vertically through the holes 23 without being unable to dissipate under the base 20 . A protruding closed ring 24 is installed on the side of the housing 41 away from the plate-like structure, relative to the acupressure plate 22 and at a position higher than the plate-like structure. When the housing 41 is combined with the base 20, the housing 41 is in close contact with the protruding closed ring 24 of the base 20 to form a closed waterproof space s. The waterproof space s can be used to waterproofly accommodate the conductive circuit assembly 30 connection terminals, which will be described in detail below.

According to the present invention, at least one bottom surface of the base 20 is fixed on the main plane 11, so that the base can float on the main plane, so that when the body surface moves, the base 20 does not need to be deformed and can maintain a stable combination with the main plane 11. And the base 20 and the main plane 11 can therefore be misaligned to create a space where air can flow, helping water vapor to evaporate. At least one part of the base 20 is floatingly fixed to the main plane 11 by adhesive bonding or by destroying the physical or chemical properties of the materials of the base 20 and the main plane 11 , such as ultrasonic welding technology.

Please see FIG. 6 , which is a top view of the conductive circuit assembly 30 . The conductive circuit assembly 30 has a plurality of mutually independent conductive circuits 31 and is fixed on the flexible fiber base material 10 . For convenience of explanation, this embodiment takes three conductive lines as an example. In practice, the number of conductive lines can be more or less. In this embodiment, the conductive circuit 31 (shown in dashed lines) is formed by placing a conductive layer on a flexible resistive carrier 32 , and the conductivity of the conductive layer is higher than that of the flexible resistive carrier 32 . The flexible resistive carrier can be polycarbonate (PC), polyethylene terephthalate (PET), polymethyl methacrylate (Poly(Methylmethacrylate), PMMA), polyimide It is formed of diaphragm materials such as (Polyimide, PI) and polypropylene (Polypropylene, PP). The conductive layer can be shielded between the flexible resistive carrier 32 and the flexible fiber base material 10 without any conductive layer being exposed. Generally speaking, water vapor can be prevented from interfering with the potential change characteristics of the conductive layer. Each conductive line 31 has a transfer end 31a and a connection end 31b respectively. At least two transfer ends 31a are located on the main plane 11 so that the conductive lines 31 extend near the main plane 11 to form a detection system for detecting the upper chest of mammals. Position at least two electrode points where body surface potential changes. An adapter end 31 a is located on the secondary plane 13 . All connecting ends 31b extend to the base 20, are exposed in the protruding closed ring 24, and extend into the aforementioned waterproof space s.

As shown in FIG. 2 , each adapter terminal 31 a is electrically coupled to an adhesive electrode 70 attached to the mammalian chest skin through a connecting conductive wire 80 , so that the potential changes of the conductive line 31 and the adhesive electrode 70 remain the same. According to the present invention, the adhesive electrode 70 has conductive properties and can be a wet or dry electrode containing adhesive additives such as conductive gel, conductive carbon glue or conductive rubber. The adhesive electrode 70 can also be directly connected to the conductive layer. Electrical coupling shortens the transmission path of potential changes to reduce interference from external noise. In addition, depending on the number of the adhesive electrodes 70, physiological signals of different leads can be detected. For example, three adhesive electrodes can detect a three-lead (3-lead) electrocardiogram signal. Further explanation. The transfer end 31a is further electrically connected to a public electrical contact 31c. Both ends of the connecting conductive wire 80 are respectively provided with a female electrical contact 81, one of which is mechanically and electrically coupled to the sticky electrode 70, and the other female electrical contact 81 is mechanically and electrically coupled to the public electrical contact 31c. Please see Figure 7, which is a cross-sectional view of a connecting end 31b. A conductive through hole h is opened at the connection end 31b and passes through the flexible impedance carrier 32. The conductive through hole h is filled with conductive glue g1 for electrically coupling the processing circuit 42 (first connection terminal 43) of the signal processing assembly 40 with the conductive through hole h. layer. The surface of the conductive through hole h is surrounded by a conductive surface layer g2 that is electrically connected to the conductive through hole h, and the area of the conductive surface layer g2 is larger than the area of the conductive through hole h, so that the processing circuit 42 and the connection terminal 31b can be electrically coupled easily and stably. Please see FIG. 8 , which illustrates the connection between the conductive circuit assembly 30 and the base 20 . All connecting ends 31b on the conductive circuit assembly 30 extend to the base 20 and are located below the protruding closed loop 24. At the same time, the base 20 bulges upward to form a protrusion there. Therefore, the connection terminals 31b are located farther than the conductive circuit assembly 30. The remainder is away from the mammal's chest skin. The advantage of this approach is to further prevent moisture from invading the connection end 31b. Preferably, the connection end 31b forms at least an R angle at the connection point with other parts of the conductive circuit assembly 30, so that both ends of the connection point can conform to the base 20 and the flexible fiber substrate 10.

According to the present invention, the conductive circuit assembly 30 may include a plurality of fixed rings 33 . Each fixed ring 33 surrounds the adapter end 31a of the corresponding conductive circuit to prevent moisture from directly contacting the adapter end 31a and affecting the signal quality. A downward opening o is formed on the fixing ring 31a to guide the outward extension direction of the connecting conductive wire, and prevent moisture from accumulating in the fixing ring 33. In addition, as can be seen from FIG. 2 , the area of the conductive circuit assembly 30 is smaller than the area of the flexible fiber base material 10 , which facilitates water vapor evaporation from the flexible fiber base material 10 .

Please see FIG. 9 , which is a perspective view of the signal processing assembly 40 . The signal processing assembly 40 includes the aforementioned housing 41 and processing circuit 42 . The housing 41 is an external protective structure of the signal processing assembly 40 and can be detachably combined with the base 20 . When the first connection terminal 43 passes through the housing 41, it is included in a cavity formed on the surface of the housing 41. The cavity protects the first connection terminal 43 from direct contact with moisture or damage due to collision. Please see FIG. 10 , which is another perspective view of the signal processing assembly 40 . A plurality of openings 44 are formed on the surface of the housing 41 outside the joint point with the base 20 . An opening 44 is installed with an elastic operating block 45 having an identifiable appearance. The elastic operation block 45 is connected with the processing circuit 42 via a signal. Pressing the elastic operation block 45 can cause the processing circuit 42 to trigger the operation function. An indicator light 46 is installed in the other opening 44. The indicator light 46 is connected with the processing circuit 42. When the processing circuit 42 triggers the operation function, the indicator light 46 lights up. The light signal of the indicator light 46 is usually orange or red, or an abnormality warning with a fixed flashing frequency. Please see FIG. 11 , which is a cross-sectional view of the signal processing assembly 40 when combined with the base 20 . A horizontal transparent gap G is formed between a surface of the casing 41 of the signal processing assembly 40 and the upper surface of the base 20 so that water vapor can circulate horizontally here, so that the holes 23 of the base 20 are in contact with the horizontal transparent gap G. G synthesizes a two-way channel connected vertically and horizontally to facilitate the evaporation of moisture on the skin and the flexible fiber base material 10 through the two-way channel.

Please also refer to Figure 2, Figure 5 and Figure 9. The processing circuit 42 is connected to at least one second connection terminal 47 that can transmit electrical signals. The at least one second connection terminal 47 is discretely distributed on the housing 41 as a processing circuit. Route 42 is the interface for signal transmission with external systems. In this embodiment, one second connection terminal 47 is used as an example for explanation. In practice, the plurality of two connection terminals 47 can also become a standard interface, such as a USB-A or USB-C socket, for signal transmission. In order to prevent the at least one second connection terminal 47 from being accidentally touched or used when the processing circuit 42 transmits non-processing signals to the outside, the base 20 has a special design. The base 20 has an extending portion 25 perpendicular thereto. When the housing 41 and the base 20 are combined, the extension 25 can cover the at least one second connection terminal, blocking the connection and signal transmission with the external system. The base 20 needs to be further disassembled from the housing 41 and connected with the external system. Connection and signal transmission can take place.

The processing circuit 42 is an assembly of electronic components enclosed inside the housing 41 and has a plurality of first connection terminals 43. Each first connection terminal 43 passes through the housing 41 and is electrically coupled to the connection end 31b of the corresponding circuit. , process the physiological signals reflected by the potential changes sensed by the adhesive electrodes 70, and transmit the results to an external system, such as a server for analyzing signals. The first connection terminals 43 and the connection ends 31b are located in the aforementioned waterproof space s to prevent external moisture from intruding. In addition to the aforementioned functions, the processing circuit 42 also has the following functions. First, when the processing circuit 42 is running, the processing circuit 42 detects the potential change of each adhesive electrode 70 over time based on the connection terminals 31b, determines the fixed state of the adhesive electrodes 70 on the body surface, and generates a When the fixation state is abnormal, the display command is used to control the indicator light 46 to emit an indicator light signal of a specific color or flashing frequency to reflect the abnormal fixation state of the adhesive electrodes 70 . In addition, the processing circuit 42 can also detect a front-end signal of the time-varying potential of each sticky electrode 70 from the connection terminals 31b, continuously convert the front-end signals into a terminal signal, and copy or wirelessly copy the terminal signal. It is transmitted to a computer system (not shown) outside the physiological signal sensing device 1, and the normal or abnormal physiological signals are graphically displayed by the computer system. Physiological signals include electrocardiograms, brain wave signals, myoelectric signals and other time-potential change signals that can be recorded based on electrode contact at various body surface locations. In order for the computer system to receive accurate data for analysis, the terminal signal needs to make some adjustments. According to the present invention, the terminal signal and the front-end signal have the same or shorter time length. degree, but there are significant potential changes. That is, the front-end signal is processed by compression, modulation or amplification to form the terminal signal, which is conducive to the rapid copying, transmission and image display of the signal.

Please see Figure 12, which shows the physiological signal sensing device 1 installed on human skin. This embodiment is explained using humans as an example of mammals. When the two covering layers 60 are removed, the flexible fiber base material 10 is adhered to the human chest through the adhesive layer 50 . When the main plane 11 and the auxiliary plane 13 of the flexible fiber base material 10 are respectively attached to the human body, the horizontal position of the main plane 11 is higher than the auxiliary plane 13, and the two transfer ends 31a (which are female electrical connections) located on the main plane 11 (shielded by point 81) are also higher than the adapter end 31a on the secondary plane 13. The adapter end 31a and the adhesive electrode attached to the thoracic skin of the mammal are electrically coupled through a connecting conductive wire 80, and one end point of the connecting conductive wire 80 can be rotated with the center point of the adhesive electrode 70 as the axis. Comply with the possible movement changes of the adhesive electrode 70 when attached to the body surface, and maintain the stability of attachment. The extension range of the main plane 11 of the flexible fiber base material 10 is at least beyond the above transfer ends 31a and the base 20 (as shown in the gray bottom part in Figure 12), forming a continuous and uninterrupted extension area of the main plane 11. Attached to skin. The adapter end 31a is exposed outside the base 20 and has a conductive public electrical contact 31c for mechanical and electrical coupling with the female electrical contact 81 . According to the present invention, the area formed by the main plane 11 is larger than that of the secondary plane 13 . In this embodiment, the distance between the center points of the adapter end 31a on the main plane 11 and the auxiliary plane 13 is at least 1 cm, and when the center points are connected to each other, they can form a triangle shape with at least one side shorter. According to the present invention, at least two first adhesive electrodes 71 are attached to the human body above the level of the xiphoid process, and are electrically coupled with the processing circuit 42 through the conductive lines 31 on the main plane 11 . A second adhesive electrode 72 is attached to the part of the human body including the level of the xiphoid process and below, and is electrically coupled to the processing circuit 42 through the conductive lines 31 on the secondary plane 13 and the extension section 12 . The position of the first adhesive electrode 71 should be higher than the lowest hanging point of the electrically coupled connecting conductive wire 80 , so that the moisture on the connecting conductive wire 80 can be directed to the lowest hanging point of the connecting conductive wire 80 instead of accumulating. At both ends of the connecting conductive wire 80 , the adhesion and signal quality of the second adhesive electrode 72 are affected.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some modifications and modifications without departing from the spirit and scope of the present invention.
