1 is a schematic view showing a smart pad of the present invention.

The illustrated smart pad may include a pad unit 170, a pattern unit 130, and a processing unit 150.

The pad unit 170 may be formed in a plate shape as a member that receives the urine of the user.

The pad unit 170 may be disposed on the various support members 90. The support member 90 may vary from bed, duvet, floorboard, floor to floor, and the like.

The pad unit 170 may be provided integrally with the diaper.

Without being limited to this, the pad unit 170 may be attached to or detached from the garment 110 to be filled between the legs, such as a diaper or underwear. When detached from the garment 110, the pad unit 170 may be provided with a detachable unit 175. When one surface of the pad portion 170 receiving urine and the other surface opposite to the one surface of the pad portion 170 are defined, the detachable portion 175 may be formed on the other surface of the pad portion 170.

Smart pad of the present invention can automatically detect the user's urine. The pattern unit 130 and the processing unit 150 may be used to detect urine.

The pattern unit 130 may be formed in the area receiving the urine of the user in the pad unit 170 and may communicate with electricity. The pattern unit 130 may include a wire through which electricity is communicated, or may include a pattern in which conductive ink is printed in a linear shape.

The pattern unit 130 may be installed on one surface of the pad unit 170 in contact with the skin of the user or inside the pad unit 170. When installed in the pad unit 170, the pattern unit 130 may be made of a metal wire in which electricity is communicated. However, when the pattern unit 130 is installed on one surface of the pad unit 170 facing the skin, it may be difficult to install the metal wire in consideration of the user's wearing comfort. In order to be formed at various locations, the pattern unit 130 may be a conductive polymer compound printed in a set pattern. In other words, the pattern unit 130 may include conductive ink.

The pattern unit 130 may be formed of conductive ink. Since the conductive ink is a liquid, the pattern unit 130 may be completed by simply drawing a pattern with the conductive ink on the pad unit 170.

For example, the conductive polymer compound may include polypyrrole obtained by electropolymerizing pyrrole. Since polypyrrole has a non-toxic property, it may be printed on the pad portion 170 facing the skin. Of course, it may be formed inside the pad unit 170.

The pattern unit 130 may include a mixture of polypyrrole, water, resin, and acetyl. Polypyrrole is an electrically conductive material that can replace metal conductors. The resin may perform an adhesive function to allow the polypyrrole to adhere to various layers constituting the pad unit 170. Acetyl can be volatilized after dissolving polypyrrole and resin in water.

Specifically, the pattern portion 130 may be a polypyrrole having electrical conductivity is attached to the area receiving the urine of the pad portion by the resin. The pattern portion 130 may be formed by applying the forming solution to the area receiving the urine in the same shape as the set pattern and then drying the forming solution. At this time, the forming solution may include polypyrrole, water for dissolving polypyrrole, resin, acetyl for dissolving resin and mixing with water.

When the pattern unit 130 is formed of conductive ink, the pattern unit 130 may be difficult to access and output an electrical signal since the pattern unit 130 is merely a pattern printed on the pad unit 170. A metal terminal may be required to electrically connect the pattern unit 130 to the processing unit 150. The first connection terminal 139 detachable from the processing unit 150 may be provided at an end portion of the pattern unit 130. The first connection terminal 139 may be formed in a metal tip button shape.

The processing unit 150 may be provided with a second connection terminal 159 detachable from the first connection terminal 139. The processing unit 150 may be electrically attached to or detached from the pattern unit 130 by the second connection terminal 159 detachable from the first connection terminal 139.

The processing unit 150 may be provided with a communication module (not shown) and a battery (not shown).

The communication module may wirelessly communicate with a user's portable terminal or an access point in the vicinity. The communication module may transmit an external control signal to the processing unit 150 or transmit the presence or absence of urine or the amount of urine detected by the processing unit 150 to the outside.

The battery may provide power required for generation of an electrical signal applied to the pattern unit 130 and driving power of the communication module.

Preferably, the processing unit 150 includes a communication module and a battery, and the processing unit 150 is attached to or detached from the pattern unit 130. According to this, the processing unit 150 that can be repeatedly used can be easily moved, does not need to be discarded after one use, and can be easily connected to various types of pad units 170. The processing unit 150 having a communication module and a battery may be manufactured in a small size so as to be portable.

2 is a schematic view showing another smart pad of the present invention.

The pad portion 170 may be disposed on the support member 90.

The processing unit 150 may include a cable connected to an external power source, and generate an electrical signal using the external power transferred through the cable. The processing unit 150 connected to an external power source through a cable may have a relatively large volume and a large weight as compared with the embodiment of FIG. 1. This is because a conversion unit for converting external power into power required for generating an electrical signal may be added.

In order to effectively use the large-scale processing unit 150, the display unit 151 may be provided in the processing unit 150. The display unit 151 may display the presence or absence of urine detected by the processing unit 150 or the amount of urine.

The pad unit 170 may be contaminated by urine of the user. Therefore, it is better to replace it at the appropriate time. When the pad unit 170 and the processing unit 150 are integrally formed, the management of the pad unit 170 becomes difficult, so that the processing unit 150 may be detachably attached to the pad unit 170. For example, the processing unit 150 may be electrically connected to or separated from the pattern unit 130 by the first connection terminal 139 and the second connection terminal 159.

The processing unit 150 may generate an auxiliary signal used for heating the pattern unit 130. According to the auxiliary signal, since the pattern unit 130 performs a function similar to the heater, the pad unit 170 may also function as a heating mat.

The processor 150 may provide an electrical signal to the pattern unit 130 together with an auxiliary signal for detecting urine. The processor 150 may divide a signal returned from the pattern unit 130, that is, an output signal of the pattern unit into an electrical signal and an auxiliary signal. In addition, the processing unit 150 may determine the presence or absence of urine or the amount of urine using the electrical signal extracted by distinguishing it from the auxiliary signal.

Although driven by external power, the processing unit 150 may be provided with the communication module described above.

3 is a schematic view showing another smart pad of the present invention.

The pad unit 170 may be attached to or detached from the garment 110 using the detachable unit 175. 3 shows a state in which the pad unit 170 is mounted on the diaper or the diaper type underwear.

The processing unit 150 electrically connected to the pattern unit 130 may be drawn out of the outer garment worn by the user, or may be mounted on the outer surface of the garment 110 or underwear. One side of the processing unit 150 may be provided with a mounting portion 157 detachable to the outer surface of the garment 110 or the outer surface of the underwear.

4 is a cross-sectional view showing the pad unit 170 according to an embodiment of the present invention.

The pad unit 170 may be a stack of the double knit layer 41, the mesh layer 43, and the detachable unit 175 in the direction from the skin of the user toward the pad unit 170.

The double knit layer 41 facing the skin may include natural fibers such as cotton so as to have a soft and thick touch. The double knit layer 41 may be formed in a plate shape having a predetermined thickness by laminating natural fibers.

The double knit layer 41 through which urine passes may include a nonwoven fabric that is lighter than natural fibers such as cotton. When the double knit layer 41 is made of a nonwoven fabric absorbing surface, it is light in weight and can improve wearing comfort. In addition, if the double knit layer 41 is formed of a nonwoven fabric, the absorbency for absorbing urine from the skin can be improved and the barrier property for urine absorbed by the mesh layer 43 to flow back to the skin can be improved.

The mesh layer 43 may be a porous material so that urine absorbed through the double knit layer 41 is easily passed. The mesh layer 43 may include cotton, which is a multi-transport material that helps absorption of urine. Microscopic structure of the cotton constituting the mesh layer 43 may be formed in a mesh shape with holes. The mesh layer 43 may maintain the double knit layer 41 in a plate shape.

On one surface of the detachable portion 175 facing the diaper, a pattern portion 130 printed with conductive ink may be formed, and the other surface of the detachable portion 175 may be formed of a waterproof film to prevent urine from leaking to the outside. Can be.

The detachable part 175 may include a velcro and the like detachable to clothing 110 such as an undergarment and a diaper. The detachable part 175 may be firmly attached to the mesh layer 43 of the pad part 170 that maintains the shape of the double knit layer 41.

The pattern unit 130 may be interposed between the double knit layer 41 and the mesh layer 43 in order to protect the pattern unit 130 and improve a user's wearing comfort, and the mesh layer 43 and the detachable unit 175 may be interposed between the double knit layer 41 and the mesh layer 43. It may be interposed between), it may be provided in the removable portion 175 itself. The pattern part 130 may be one in which one surface of the double knitted layer 41, the mesh layer 43, and one surface of the detachable part 175 may be printed with a conductive polymer compound in a set pattern.

The pad portion 170 may be lined with electricity by the pattern portion 130.

The processing unit 150 may supply an electrical signal for detecting urine to the pattern unit 130. The pattern unit 130 may have a flexible property that is bent together with the pad unit 170.

The processing unit 150 may include a battery that provides driving power, and needs to be driven for a long time by using a limited charging power of the battery. For long term driving, the processing unit 150 may operate to save driving power. Even if the processing unit 150 is operated by external power, power consumption may be reduced.

For example, the processing unit 150 may include a first mode for supplying a first electric signal to the pattern unit 130 or a second electric signal for supplying a second electric signal having a stronger current value than the first electric signal to the pattern unit 130. Can operate in 2 modes.

The first mode may be a real time or a set cycle, and may be an operation mode for detecting the presence or absence of urine. The pattern unit 130 may include a first basic pattern 131 and a second basic pattern 132 spaced apart from each other. The first basic pattern 131 and the second basic pattern 132 may be connected to the processing unit 150. The processor 150 may supply the first electrical signal to the first basic pattern 131, and analyze the electrical signal output from the second basic pattern 132, that is, the electrical signal returned from the pattern unit 130. have.

When urine does not adhere to the pad unit 170, the first electrical signal may not be transmitted to the second basic pattern 132, and thus no electrical signal is output from the second basic pattern 132. If the user urinates, the urine may spread over the first basic pattern 131 and the second basic pattern 132. Urine buried over the first basic pattern 131 and the second basic pattern 132 may serve as a conductive line that electrically connects the first basic pattern 131 and the second basic pattern 132. Therefore, the first electrical signal supplied to the first basic pattern 131 may be introduced into the processing unit 150 via the first basic pattern 131, the urine, and the second basic pattern 132.

The processor 150 may determine that urine is generated when the first electrical signal is received from the second basic pattern 132.

The processing unit 150 may be operated in the second mode if urine is detected during the operation of the first mode. The second mode may be an operation mode in which the amount of urine is determined using the second electrical signal. The second mode can determine the amount of urine using the current change or the voltage change of the electrical signal. In order to clearly distinguish a change in current or a change in voltage, the second electrical signal may have a stronger current value than the first electrical signal.

The second electrical signal may be used in the first mode, but when the second electrical signal is applied to the first mode that is always operating or periodically operating, power consumption of the battery may be severe. Therefore, it is usually difficult to detect the amount of urine, but it is good to supply the first electric signal of strength that can grasp the presence or absence of urine. In addition, when urine is detected, when the second electric signal is supplied, urine may be detected while minimizing power consumption, and the amount of urine may be determined.

On the other hand, the processor 150 may utilize the first electrical signal supplied in real time or according to a set period for low frequency treatment.

5 is a schematic view showing a pattern portion 130 of the present invention.

The pattern unit 130 may include a first basic pattern 131 and a second basic pattern 132 that are formed in a line shape extending in a setting direction and connected to the processing unit 150. The first basic pattern 131 and the second basic pattern 132 may extend in parallel to each other.

The electrical signal s _in supplied from the processing unit 150 may be applied to the first basic pattern 131.

The second basic pattern 132 may be disposed at a position spaced apart from the first basic pattern 131. Since the first base pattern 131 and the second base pattern 132 are electrically disconnected from each other in a distance, they may be electrically disconnected.

When urine adheres to the pad portion 170 across the first basic pattern 131 and the second basic pattern 132, the electrical signal s _in applied to the first basic pattern 131 is urine to form the second basic pattern. 132 may be passed.

The processing unit 150 may detect urine using the electrical signal s _out transmitted from the second basic pattern 132.

The electrical signal s _in , which is provided to the pattern unit 130 through the processing unit 150, in particular, the first electrical signal may be a low frequency signal that passes through the body and is capable of low frequency treatment. When the electrical signal s _in supplied to the pattern unit 130 is a low frequency signal whose amplitude changes, it is difficult to detect the presence or absence of urine using the change in amplitude. Therefore, the processing unit 150 may monitor the offset of the electrical signal returned from the pattern unit 130. If the offset is outside the set range, it may be determined that urine is present.

When the low frequency signal is applied to the first basic pattern 131, the electrical signal s _in (input signal) may be output as the electrical signal s _out (output signal) to the second basic pattern 132 through the skin of the user even if there is no urine. have. At this time, the offset of the current of s _out may be i1.

However, if the urine generated by the user is buried over the first basic pattern 131 and the second basic pattern 132, the resistance between the first basic pattern 131 and the second basic pattern 132 due to urine Can be lowered. Thus, if the voltage at s _in is the same, the current offset at s _out will be high. In this case, if the increased current offset value is higher than the set range, the processing unit 150 may determine that urine exists.

In order to accurately detect the urine, the first basic pattern 131 and the second basic pattern 132 may be formed to be complicatedly intertwined with each other. When the first basic pattern 131 and the second basic pattern 132 are formed to be intricately intertwined with each other, it may be difficult to manufacture the first basic pattern 131 and the second basic pattern 132. Accordingly, the first basic pattern 131 and the second basic pattern 132 may be formed in a state in which they extend in one direction, and another additional pattern may be formed.

For example, a plurality of first wing patterns 133 may be formed on the first basic pattern 131, and a plurality of second wing patterns 134 may be formed on the second basic pattern 132.

The first wing pattern 133 may protrude from the first basic pattern 131 toward the second basic pattern 132.

The second wing pattern 134 may protrude from the second basic pattern 132 toward the first basic pattern 131.

The first wing pattern 133 and the second wing pattern 134 may be alternately disposed along the length direction of the first basic pattern 131 and the second basic pattern 132. In this case, the first basic pattern 131 and the first wing pattern 133 may be spaced apart from the second basic pattern 132 and the second wing pattern 134.

The processing unit 150 may determine the pattern areas L1 and L2 of the urine buried in the pattern unit 130 using the current value of the electrical signal s _out returned from the pattern unit 130. The processing unit 150 may estimate the urine areas ⓐ and ⓑ of the urine buried in the pad unit 170 using the pattern area.

It is assumed that the area of the urine-embedded or smeared area in the pad unit 170, that is, the urine area is ⓐ. In the case of urine area ⓐ, one first wing pattern 133 and one second wing pattern 134 may be electrically connected by urine.

The processing unit 150 measures the electric signal returned from the pattern unit 130, that is, the electric current of the electric signal s _out output from the pattern unit 130, and uses the measured current value to measure the first wing pattern (eg, urine). The number of 133 and the number of second wing patterns 134 may be determined. For example, when one wing pattern and one second wing pattern 134 are urine spread, the first basic pattern 131 and the second basic pattern 132 pass through a first resistor corresponding to the resistance of urine. It can be connected. At this time, the current value of s _out is a value obtained by dividing the voltage value of s _in by the resistance value of the first resistor. Using this, the processing unit 150 may determine the resistance value of the first resistor and the area L1 of the pattern of the urine that forms the first resistor using the current value of s _out . Since the first resistor may be in a state with a significantly high resistance value, the current value of s _out will be in a considerably low state. Since the urine in the liquid state is inferred in an elliptical spread state in the radial direction or the shape of the pad portion 170 while including the pattern area L1 (including the distance between the patterns of urine), the processing unit 150 uses L1. Urine area ⓐ can be identified.

On the other hand, in the urine area ⓑ, two first wing patterns 133 and two second wing patterns 134 may be electrically connected by urine. When the resistance of the urine connecting the two first wing patterns 133 and the two second wing patterns 134 is defined as the second resistor, the resistance of the second resistor is smaller than the resistance of the first resistor.

Therefore, the current value of s _out at the time of the second resistor is larger than the current value of s _out at the time of the first resistor. The processing unit 150 may determine the resistance value of the second resistor and the area L2 of the urine pattern forming the second resistor using the current value of sout. The urine spreads in an elliptical shape according to the radial direction or the shape of the pad portion 170 while including the pattern area L2, so that the processing unit 150 can determine the urine area ⓑ using L2.

The processing unit 150 may determine the urine areas ⓐ and ⓑ of the urine deposited on the pad unit 170 by using the pattern unit 130, and estimate the amount of urine using the urine areas ⓐ and ⓑ.

For example, the total amount of urine may be calculated by multiplying the amount of urine per unit area of the pad unit 170 absorbing urine or the amount of urine per unit area buried on the pad unit 170 by the urine area. The amount of absorption per unit area or the amount of urine per unit area may be input to the processing unit 150 in advance by the manufacturer.

The pattern unit 130 may be formed differently to determine the amount of urine.

6 is a schematic view showing another pattern portion 130 of the present invention.

When the first basic pattern 131 and the second basic pattern 132 form one pattern group, a plurality of pattern groups may be connected to the processing unit 150.

Each pattern group may extend along the direction in which the pad unit 170 extends.

When urine gets on the pad unit 170, the urine is spread in a circle. Therefore, the length of urine across each pattern bath is different for each pattern bath. Since the resistance between the first basic pattern 131 and the second basic pattern 132 provided in the pattern bath in which the urine is extended in the long length section L4 becomes low, the current becomes large. On the other hand, in the case of the pattern bath in which the urine spans the short length section L3, the current becomes small.

The processing unit 150 may extract a pattern bath having the largest current value among the plurality of current values obtained from the plurality of pattern baths, and calculate a length of 2R of urine that spans the pattern bath. Correlation between the length of urine and the current value across the pattern bath may have been obtained through preliminary experiments. The pattern bath with the largest current value can be estimated to pass through the center of the urine stained soil. Therefore, if the length of urine is attached to the pattern tank having the largest current value, the urine area can be easily obtained by the circle area formula.

The total amount of urine can be calculated by multiplying the obtained urine area by the absorption amount per unit area of the pad unit 170.

Smart pad of the present invention to determine the presence of urine and the amount of urine through the pattern unit 130 and the processing unit 150, it is possible to treat low-frequency. In addition, it can be applied to the existing clothing 110 or underwear for the purpose of simply receiving the urine using the removable portion 175.

7 is a schematic view showing the shape of the pattern portion of the present invention.

When detecting the amount of urine using the current value or the voltage value of the output signal of the pattern portion 130, it is necessary to consider the extension length of each basic pattern.

The pattern unit 130 may also have a resistance.

It is assumed that the same amount of urine is buried at points close to and far from the processing unit 150 with respect to the processing unit 150. In this case, the urine region formed at a point close to the processing unit 150 will be referred to as ⓒ and the urine region formed at a point far from the processing unit 150 will be referred to as ⓓ.

Since the amount of urine is the same, the current value i3 due to the urine area ⓒ and the current value i4 due to the urine area ⓓ should be the same, so that the processing unit 150 can determine the amount of urine without error.

However, the resistance of the pattern portion from the processing portion 150 to the urine region ⓒ is smaller than the resistance of the pattern portion from the processing portion 150 to the urine region ⓓ. Therefore, when the voltage is fixed due to the difference in the resistance value, the current value i3 becomes larger than the current value i4.

Since the processing unit 150 that cannot detect the position where the urine region is formed calculates the amount of urine using only the current value, the urine amount in the urine area ⓒ and the urine amount in the urine area ⓓ are different. In order to reduce the amount of urine grasp errors, a method of forming i3 and i4 in the same manner may be prepared.

For example, the distance L1 between the center of the first wing pattern and the center of the second wing pattern may be constantly formed to detect the accurate urine area regardless of the position. The farther away from the processing unit 150, the thickness w of the first wing pattern 133 may be thicker. As the thickness of the first wing pattern 133 increases, the distance d between the first wing pattern 133 and the second wing pattern 134 may become closer as the distance from the processing unit 150 increases.

In the urine region ⓒ, the electrical distance d between the first wing pattern 133 and the second wing pattern 134 is long, instead of the resistance of the pattern unit 130 is small.

In the urine region ⓓ, the electrical distance d between the first wing pattern 133 and the second wing pattern 134 is short, instead of having a relatively large resistance of the pattern unit 130.

Due to the difference in d, in the urine region ⓒ, the resistance value formed by urine is large, whereas in the urine region ⓓ, the resistance value formed by urine is small.

The resistance value a viewed from the processing unit 150 may be the sum of the resistance value of the pattern unit 130 itself and the resistance value formed by urine. According to the present embodiment, when the resistance value of the pattern unit 130 itself becomes larger, the resistance value formed by urine becomes smaller, so that the resistance value a can be kept constant at all times. Accordingly, the output signals i3 and i4 formed due to the urine areas ⓒ and ⓓ of the same area may be the same. As a result, the processing unit 150 may accurately grasp the amount of urine regardless of the position of the urine on the pattern unit 130.

For reference, the thickness w of the second wing pattern 134 may also become thicker as it is disposed away from the processing unit 150.

8 is a schematic view showing another shape of the pattern portion of the present invention.

8 discloses a method of keeping i3 and i4 the same by adjusting the thickness of each basic pattern.

The first basic pattern and the second basic pattern may extend parallel to each other.

As the distance from the processing unit 150 increases, the thickness of the first basic pattern 131 may become thicker in the direction toward the second basic pattern 132. The second basic pattern 132 may be thickened in a direction toward the first basic pattern 131.

Specifically, the inner side facing each other base pattern in each base pattern may be inclined in the direction toward the other base pattern. On the other hand, the outer sides forming each basic pattern may extend in parallel to each other. Therefore, the interval d1 between the outer sides of each basic pattern can be kept constant. Since d1 remains constant, the urine area can be determined regardless of location. On the other hand, since the inner side is formed to be inclined, each basic pattern may be thicker as it moves away from the processing unit 150.

Due to an increase in the thickness of the first basic pattern 131, the first basic pattern 131 and the second basic pattern 132 may be closer to each other as they move away from the processing unit 150. For example, in FIG. 8, a distance d3 between the first basic pattern 131 and the second basic pattern 132 facing the urine region ⓓ far from the processing unit 150 may be small. On the other hand, the distance d2 between the first basic pattern 131 and the second basic pattern 132 facing the urine region ⓒ close to the processing unit 150 may be smaller than d3.

Therefore, even if the urine regions ⓒ and ⓓ of the same area are formed at different positions in the length direction of the basic pattern, the output signal i3 generated due to the urine region ⓒ and the output signal i4 generated due to the urine region ⓓ may be the same. have.
