Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present utility model. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Fig. 1 is one of schematic structural diagrams of a wearable device according to an embodiment of the present utility model, and referring to fig. 1, the wearable device includes:

the device comprises a device body 1, wherein the device body 1 is a wearing garment; the electrode assembly 2 is electrically connected to a first position of the device body 1, wherein the first position is at least one part of positions corresponding to the positions of the device body 1, where the positions of the device body 1 where the breathing of the human body changes when the device body 1 is worn on the human body; the electrode assembly 2 includes at least two electrode sheets disposed opposite to each other, and an electrical signal between the at least two electrode sheets included in the electrode assembly 2 is changed when the device body 1 is expanded and contracted.

When the user breathes while wearing the wearable device, electrical properties between at least two electrode sheets included in the electrode assembly 2 change, such as electrical properties of resistance, inductance, capacitance, etc. between at least two electrode sheets included in the electrode assembly 2 change, which is not limited by the embodiment of the present utility model.

The electrode assembly 2 is located at a first position of the apparatus body 1, where a portion where a change in breathing of a human body occurs is at least one of corresponding positions on the apparatus body 1, such as a position corresponding to a chest or an abdominal cavity, in a case where the apparatus body 1 is worn on the human body. That is, as shown in fig. 2, the electrode assembly 2 may be provided in the chest, as shown in fig. 3, or the electrode assembly 2 may be provided in the abdominal cavity, or as shown in fig. 4, the electrode plates may be provided in the chest and the abdominal cavity to form the electrode assembly 2, which is not limited in the embodiment of the present utility model.

It should be noted that, since respiration causes changes in the chest and/or abdominal cavity, the tidal volume of the human body is proportional to the changes in the perimeter of the chest and/or the perimeter of the abdominal cavity, or is proportional to the changes in the volume of the chest and/or the volume of the abdominal cavity. The electrode assembly 2 is thus disposed at a position corresponding to the apparatus body 1 and a position where the breathing of the human body is changed, i.e., at least one position in the chest or abdominal cavity of the human body, that is, tidal volume information is reflected by the change of at least one position in the chest or abdominal cavity of the human body. Thus, tidal volume information can be quantitatively reflected through changes of at least one part in the chest or abdominal cavity of the human body during the respiration of the human body. Wherein, the tidal volume refers to the amount of air inhaled or exhaled by the human body each time the human body breathes.

In some embodiments, after the user wears the wearable device, an electrical signal between at least two electrode pads included in the electrode assembly 2 may be acquired, an average cross-sectional area of at least one of the chest cavity or the abdominal cavity, and a height of the at least one of the chest cavity or the abdominal cavity may be determined from the electrical signal, a volume change of the at least one of the chest cavity or the abdominal cavity may be determined from the average cross-sectional area and the height, and the volume change may be determined as a tidal volume. Or determining the change of the cross-sectional area of at least one part in the thoracic cavity or the abdominal cavity according to the electric signal, then obtaining the volume change according to multiplying the change of the cross-sectional area by a preset volume coefficient, and determining the volume change as the tidal volume. The preset volume coefficient reflects the corresponding relation between the cross-sectional area variable quantity and the tidal volume, the tidal volume of a user can be acquired in advance through a tidal volume measuring device, the perimeter variable quantity of at least one part in the chest or the abdominal cavity of the user when the user breathes after wearing the wearable device is acquired through a chest or an abdominal cavity perimeter measuring device, then the cross-sectional area variable quantity is calculated according to the perimeter variable quantity, and the preset volume coefficient is determined according to the cross-sectional area variable quantity and the tidal volume.

As can be seen from the above embodiments, in the embodiment of the present utility model, since the apparatus body 1 is a stretchable wearing garment; the electrode assembly 2 is electrically connected to a first position of the device body 1, wherein the first position is at least one part of corresponding positions of a part of the device body 1 where the breathing of the human body changes when the device body 1 is worn on the human body; in the case where the device body 1 expands and contracts, an electrical signal between at least two electrode sheets included in the electrode assembly 2 changes. Therefore, under the circumstance that a user wears the wearable device, as the user breathes, the device body 1 stretches and contracts, so that an electric signal between at least two electrode plates included in the electrode assembly 2 changes, and then at least one position in a position where the user breathes in a human body can be perceived through the changed electric signal to change due to breathing, and then tidal volume information can be quantitatively reflected through the change of at least one position in the position where the user breathes in the human body. Therefore, the wearable device provided by the embodiment of the utility model not only can be convenient for a user to wear and monitor the tidal volume of the user in real time, but also can avoid the installation and the dismantling of the electrode by a professional technician, thereby improving the measurement efficiency.

For a specific composition and placement of the electrode assembly 2, in some embodiments, the electrode assembly 2 includes: at least one first electrode sheet 21, the first electrode sheet 21 being disposed at a second position of the apparatus body 1; at least one second electrode piece 22, the second electrode piece 22 being disposed at a third position of the apparatus body 1; wherein the first electrode piece 21 and the second electrode piece 22 are oppositely arranged, and the second position and the third position are two positions of the corresponding positions of the breathing change part of the human body on the device body 1 under the condition that the device body 1 is worn on the human body; when the device body 1 expands and contracts, an electrical signal between the first electrode piece 21 and the second electrode piece 22 changes.

It should be noted that, in some embodiments, the electrode assembly 2 may be embedded in the device body 1 so that the electrode pads are in contact with a human body, and in a case that the wearable device is worn on the human body, since bioelectricity exists inside the human body, the electrical signal may be collected directly through the electrode assembly 2 including at least two electrode pads disposed opposite to each other.

The electrode assembly 2 may include at least one first electrode sheet 21 and at least one second electrode sheet 22, such as one first electrode sheet 21 and one second electrode sheet 22, or one first electrode sheet 21 and a plurality of second electrode sheets 22, or a plurality of first electrode sheets 21 and one second electrode sheet 22, or a plurality of first electrode sheets 21 and a plurality of second electrode sheets 22, and the number of first electrode sheets 21 and second electrode sheets 22 may be equal or unequal, and the number of first electrode sheets 21 and second electrode sheets 22 included in the electrode assembly 2 may be determined according to the measurement accuracy of the wearable device, which is not limited in the embodiment of the present utility model.

Because the thoracic cavity and the abdominal cavity change differently when different users breathe, for example, the thoracic cavity changes more obviously when a part of users breathe, and the abdominal cavity changes more obviously when a part of users breathe. Accordingly, the electrode assembly 2 may be disposed at least one of the chest and/or abdominal cavity of the human body in a corresponding position on the device body 1 in a state where the device body 1 is worn on the human body. Specifically, at least one first electrode tab 21 and at least one second electrode tab 22 may be disposed at least one portion of the chest of the human body in a corresponding position on the device body 1 in a case where the device body 1 is worn on the human body, or at least one first electrode tab 21 and at least one second electrode tab 22 may be disposed at least one portion of the abdominal cavity of the human body in a corresponding position on the device body 1 in a case where the device body 1 is worn on the human body, or at least one first electrode tab 21 and at least one second electrode tab 22 may be disposed at least one portion of the chest and the abdominal cavity of the human body in a corresponding position on the device body 1, respectively, in which case this embodiment is not limited, and may be determined according to an actual situation of a user. The second position and the third position may be any two positions of corresponding positions of the chest and/or the abdominal cavity of the human body on the apparatus body 1 in a case where the apparatus body 1 is worn on the human body.

Thus, through the first electrode sheet 21 and the second electrode sheet 22 arranged at two positions of the positions corresponding to the positions of the device body 1 where the breathing of the human body changes when the device body 1 is worn on the human body, the tidal volume information can be perceived conveniently through the changes of the electric signals between the first electrode sheet 21 and the second electrode sheet 22, and the practicability of the wearable device is improved.

Alternatively, the number of the first electrode sheet 21 and the second electrode sheet 22 is 1; the second position is a position corresponding to the chest or abdominal cavity of the human body on the device body 1 when the device body 1 is worn on the human body, and the third position is a position corresponding to the chest or abdominal cavity of the human body on the device body 1 when the device body 1 is worn on the human body.

Based on this, as shown in fig. 2, one first electrode tab 21 and one second electrode tab 22 may be provided in at least one of the corresponding positions of the chest of the human body on the device body 1 in the case where the device body 1 is worn on the human body, or, as shown in fig. 3, one first electrode tab 21 and one second electrode tab 22 may be provided in at least one of the corresponding positions of the abdominal cavity of the human body on the device body 1 in the case where the device body 1 is worn on the human body, or, as shown in fig. 4, one first electrode tab 21 and one second electrode tab 22 may be provided in at least one of the corresponding positions of the chest and the abdominal cavity of the human body on the device body 1, respectively.

Wherein, a first electrode sheet 21 and a second electrode sheet 22 may be respectively provided at least one of the positions corresponding to the left chest and the right abdominal cavity of the human body on the device body 1 in the case where the device body 1 is worn on the human body, or a first electrode sheet 21 and a second electrode sheet 22 may be respectively provided at least one of the positions corresponding to the right chest and the left abdominal cavity of the human body on the device body 1 in the case where the device body 1 is worn on the human body, or the first electrode sheet 21 and the second electrode sheet 22 may be provided at least one of the positions corresponding to the chest and the abdominal cavity of the human body on the same side of the device body 1, such as the right chest and the right abdominal cavity, the left chest and the left abdominal cavity, to which the present embodiment is not limited.

Thus, only through the corresponding position of the chest of the human body on the device body 1 when the device body 1 is worn on the human body, and/or the corresponding position of the abdominal cavity of the human body on the device body 1 when the device body 1 is worn on the human body, the change of the cross-sectional area or the volume of the chest and/or the abdominal cavity of the user can be determined, the structure of the whole wearable device is simplified, the cost of the wearable device is saved, and due to the reduction of the electrical elements (the reduction of the electrode plates), the wearing discomfort caused to the user due to the arrangement of the electrical elements can be reduced.

Thus, in the case where the electrode assembly 2 includes one first electrode piece 21 and one second electrode piece 22, in the case where the cross-sectional area of the chest and/or abdominal cavity of the human body is changed or the volume is changed, the change in the electric signal due to the change in the cross-sectional area or the change in the volume can be obtained only by one first electrode piece 21 and one second electrode piece 22. That is, through the above embodiment, the detection of the change in the cross-sectional area or the change in the volume of the chest cavity and/or the abdominal cavity of the human body can be completed only by one first electrode sheet 21 and one second electrode sheet 22, that is, the measurement of the tidal volume of the user is completed, which is not only beneficial to saving the manufacturing cost of the wearable device, but also beneficial to reducing the wearing discomfort caused to the user by the arrangement of the electrical elements.

Alternatively, the number of the first electrode pieces 21 is 1, and the number of the second electrode pieces 22 is plural;

The plurality of second electrode pads 22 are arranged at corresponding positions on the device body 1 at different heights on the human body in a case where the device body 1 is worn on the human body. The first direction and the second direction are two directions intersecting, for example, in the case that the first direction is a horizontal direction, the second direction is a vertical direction. When the plurality of second electrode pads 22 are arranged in the second direction, they may be arranged in a straight line, or may be arranged in a staggered manner, that is, not in a straight line, which is not limited in the embodiment of the present application. The direction of the respiration change of the human body is the direction of the thoracic cavity or the abdominal cavity fluctuation, and since the first electrode sheet 21 and the second electrode sheet 22 are positioned on the device body 1, a plane can be formed under the condition that the first direction and the second direction intersect, and under the condition that the device body 1 is worn on the human body, the direction of the thoracic cavity or the abdominal cavity fluctuation has an intersecting relationship with the plane formed by the intersection of the first direction and the second direction.

Illustratively, as shown in fig. 5, the electrode assembly 2 includes one first electrode tab e0 and a plurality of second electrode tabs e1 to e13, the second electrode tabs e1 to e13 are located on the right side of the first electrode tab e0, that is, the second electrode tabs e1 to e13 are located on one side of the first direction X where the second position of the first electrode tab e0 is located, the second electrode tabs e1 to e13 are sequentially arranged on a straight line, any one of the second electrode tabs e1 to e13 is located in a different direction of the first electrode tab e0, the first direction is a horizontal right direction starting from the first electrode tab e0, the second direction is a vertical direction Y corresponding to the straight line where the second electrode tabs e1 to e13 are located, and the first direction and the second direction are two directions intersecting.

The first direction is a horizontal right direction from the first electrode piece e0, and the second direction Y is a direction intersecting with the first direction X and perpendicular to each other.

In addition, referring to the foregoing embodiment, the change of the cross-sectional area at the corresponding position of the chest cavity or abdominal cavity on the human body can be perceived according to the change of the electric signal between the first electrode sheet 21 and any of the second electrode sheets 22. And, according to the arrangement positions of the plurality of second electrode sheets 22 corresponding to the height difference on the human body, the height difference of the body part where the human body breathes is changed can be obtained, the volume change amount when the human body breathes can be calculated according to the cross-sectional area change and the height difference, and then the volume change amount can be determined as the tidal volume.

The conductive fabric layer may be made of conductive fabric, which refers to electronic fabric with conductive properties, which may be obtained by mixing a coating layer coated with copper, nickel or silver fibers on a textile, and by various structures, braiding and combinations. When a current is passed through the conductive wire in the conductive fabric, the change in the cross-sectional area of the conductive wire causes a change in an electrical signal such as resistance. This is by way of example only, and the embodiments of the present application are not limited thereto.

The apparatus body 1 may integrally include one insulating fabric layer and one conductive fabric layer, or may integrally include one insulating fabric layer, and the conductive fabric layer is disposed at the first position of the apparatus body 1, which is not limited in this embodiment. The conductive fabric layer can be arranged on one surface of the insulating fabric layer, which is not contacted with a human body, and specifically, the conductive fabric layer can be connected with the insulating fabric layer in a bonding, spinning, clamping and other modes.

In some embodiments, the conductive fabric layer may be connected to a power source, which may apply an electrical signal to the conductive fabric layer such that current flows in the conductive wires of the conductive fabric layer. When the device body 1 is worn on a human body, the conductive fabric layer stretches and contracts along with the changes of the volume of the chest cavity and/or the abdominal cavity when the human body breathes, so that the sectional area of a wire in the conductive fabric layer changes, the change of the sectional area of the wire can cause the change of electrical signals such as resistance, and then the electrical signals between the oppositely arranged electrode plates change. The change of the electric signal corresponds to the stretching amount of the conductive fabric, and the change of the chest and/or abdominal cavity volume of the human body can be calculated according to the stretching amount of the conductive fabric, so that the tidal volume of the testee can be determined according to the change of the chest and/or abdominal cavity volume of the human body.

Elasticity refers to the ability of the material to recover, and the insulating fabric layer may be made of an insulating material having elasticity greater than that of the conductive fabric. In this way, changes in chest and/or abdominal volume as the person breathes can be better transferred through the insulating fabric layer to the conductive fabric layer and the wearing experience of the wearable device is improved.

Optionally, the conductive fabric layer comprises a carbonaceous material having conductive properties.

In some embodiments, the conductive fabric layer may be obtained by adding a carbon-based conductive agent, such as graphite, to a common fabric. Among them, graphite is conductive because the interior of the lamellar crystal contains a large amount of free electrons, and therefore, graphite has good conductivity, and the higher the purity, the better the conductivity. Thus, the conductive fabric can be more conveniently obtained, and the conductivity of the conductive fabric is improved.
