Description

Urine detection device {excreta detection device}

The present invention relates to a method for remotely detecting the occurrence of urine and feces, and more particularly, to a method of detecting the occurrence of urine and feces of a user with an electrical signal.

Recently, infants who cannot handle feces themselves, patients with poor mobility, and the elderly often wear diapers. Dispose of feces through diapers. People who wear diapers do not have the ability to handle feces themselves, and it is often difficult to inform guardians of whether or not they are discharged. If the diaper is not changed after discharge, it causes sores, eczema, infection and secondary damage. Therefore, it is necessary to quickly change the diaper after discharge.

Therefore, the guardian must frequently check the presence or absence of feces using sight, smell, and touch. However, there is a problem that it is not easy to check when a small amount of feces is discharged.

Accordingly, there is an increasing demand for automatically detecting whether urine is discharged or not, so that the guardian can know the user's urine discharge state without directly checking the urine discharge state.

A temperature sensor unit 204 is positioned below the gas sensor unit 202 . The temperature sensor unit 204 is preferably formed as an IR sensor. Therefore, the second opening is located under the gas sensor unit 202 . The temperature sensor unit 204 measures the user's skin temperature through the second opening.

The lower housing 100 includes a gas space 101 and an air hole 102 .

The gas space 101 is formed inside the lower housing 100 . Specifically, the gas space 101 is formed by combining the lower housing 100 with a gas sensor unit, an HRM sensor unit 203, and a temperature sensor unit 204 to be described later. The space formed in this way is distinguished from the inner space where the circuit board unit 200 and the like are located. The internal space where the circuit board unit 200 is located and the gas space 101 where the gas space 101 is located form another internal space. Since the gas space 101 forms a separate internal space, the gas introduced into the gas space 101 through the air hole 102 does not flow out to the circuit board unit 200 . Gas may be introduced into the gas space 101 through the air hole 102 . The introduced gas stays in the gas space 101 . Therefore, the gas sensor unit 202 measures the gas staying inside the gas space 101 . By letting the gas stay inside the gas space 101, the gas sensor unit 202 increases the contact time with the gas between gas measurements, so that an accurate measurement value can be obtained.

The air hole 102 is formed on the front surface of the lower housing 100 . The air hole 102 is formed in the form of a through hole. The air hole 102 is composed of six through-holes in an oval shape. Gas may flow into and out of the gas space 101 through the air hole 102 . Gas introduced into the gas space 101 may be measured by the gas sensor unit 202 . Although the air hole 102 of the present invention is shown as having six through holes, the air hole 102 is not limited to the shape and number of through holes.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 4 .

Figure 4 shows the urine detection device of the present invention. For convenience of description, the embodiment described with reference to FIG. 4 will be described with reference to FIGS. 1 to 3 focusing on differences from the above-described embodiment.

Referring to FIG. 4, the urine detection device of the present invention has a structure in which the cover part 400 is opened and closed through a hinge coupling in a state in which the upper housing 300, the circuit board part 200, and the lower housing 100 are coupled. .

The cover part 400 covers the upper part of the coupled housing, and a part in one direction is hinged with the upper housing 300 . Specifically, the lower portion adjacent to the rear surface of the cover unit 400 and the upper portion adjacent to the rear surface of the upper housing 300 are coupled through the elastic member 301 . Accordingly, the cover part 400 may be opened with respect to the upper housing 300 . The elastic member 301 is formed of a material that provides the elastic member 301 . Preferably it may be a spring. The shape of the elastic member 301 may be deformed and restored by an external force. When the cover part 400 is opened by 60° or less, force is provided in the opening direction by the elastic member 301 . Through the elastic member 301, the opening operation of the cover unit 400 can be performed with little force.

The opposite direction of the cover part 400 and one direction of the upper housing 300 is coupled to the fastening part 401 of the cover part 400 and the fastening groove 303 of the upper housing 300 . The fastening part 401 is formed of a pillar in the form of a giyeokja. The fastening groove 303 is formed as a groove in the shape of a digatja recessed into the inside. The pillar shape of the fastening part 401 is inserted into the recessed groove of the fastening groove 303. Therefore, the coupling between the fastening part 401 and the fastening groove 303 is formed firmly and is not opened by force acting in the opening direction applied by the elastic force of the elastic member 301 .

The release button 402 is formed on the front surface of the cover part 400 . The release button 402 is formed in a protruding column shape. The release button 402 is connected to the fastening part 401 . Through the release button 402 , coupling between the above-described fastening part 401 of the cover part 400 and the fastening groove 303 of the upper housing 300 may be opened. Specifically, when the release button 402 is pressed, the pillar shape of the fastening part 401 is separated from the inserted structure. Accordingly, the cover unit 400 may be opened with respect to the upper housing 300 by manipulating the release button 402 . Even in a state where the diaper pad is coupled to the urine detection device, the release button 402 is formed on the front surface, making it easy to operate.

The guideline 403 is formed on the upper part of the cover part 400 . The guideline 403 is formed as a marker printed on the upper surface of the cover part 400 . Guideline 403 may be inserted from top to bottom in some cases. The guideline 403 guides the diaper pad so that the conductive pattern portion of the diaper pad and the terminal portion of the urine detection device are coupled to appropriate positions when the diaper pad is coupled to the urine detection device.

In this configuration, when the urine detection device is used in combination with the diaper pad having the conductive pattern, the front surface of the urine detection device is located in the direction of the user's lower body.

A diaper pad having a conductive pattern is coupled between the cover part 400 and the upper housing 300 . When combining, guideline 403 provides a guide as to whether the combining position is appropriate. The conductive pattern of the diaper pad is combined with the protruding terminal 302 located on the top of the upper housing 300 . Each conductive pattern corresponds to each protruding terminal 302 as a pair. Specifically, since the accompanying drawings show that there are four protruding terminals 302, four conductive patterns are also formed, so that one protruding terminal 302 and one conductive pattern line face each other and are combined as a pair. am. However, the present invention is not limited to the number of protruding terminals 302 .

The urine detection device of the present invention detects a change in an electrical signal according to the occurrence of urine through a conductive pattern portion of a diaper pad. Specifically, the protruding terminal 302 detects an electrical signal received through the conductive pattern. The signal detected by the protruding terminal 302 is transferred to the antenna unit through the lower terminal unit 201 . The antenna unit transmits signals to the server. The transmitted signal is received by the server, and the desk managing the server can determine whether the user has urinated or not. Secondary damage such as sores, eczema, and infection that may occur to the user can be prevented by quickly responding to the occurrence of the user's urine.

The air hole 102 is located in the direction of the user's lower body through which gas can rise. When gas is generated in the direction of the lower body, the air hole 102 can introduce the gas into the gas space 101 more quickly than when the air hole 102 is formed on the surface in the other direction. The introduced gas stays in the gas space 101 for a while, and through this, the gas sensor unit 202 increases the gas contact time and can accurately measure the gas. Through the gas measurement value detected by the gas sensor unit 202, it helps to determine whether or not urine is generated in the diaper pad.

The LED indicator 104 is located in the direction of the user's upper body. It is possible to distinguish a state according to whether the LED of the LED indicator 104 blinks by lowering the head in the direction of the upper body. Specifically, it is possible to distinguish the display of the operating state of the urine detection device, such as connection, non-connection, and erroneous connection, through whether or not the LED is blinking.

The power port 105 is formed on one of the sides of the urine detection device. Therefore, even when the urine detection device is coupled to the diaper pad and is in use, the battery can be charged or connected to an external device through the power port 105 .

In addition, an additional sensor may be configured in the urine detection device to collect user information and determine the user's condition based on the collected information. For example, it is possible to remotely determine whether a user has fallen through a gyro sensor. In addition, it is possible to prevent bedsores by identifying a sleeping pattern or measuring how long the user has maintained the same posture, and changing the user's posture based on this. Based on this information, the desk managing the server can quickly take action appropriate to the user's condition.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 5 .

The present invention may further include a detachable portion 404 formed on the upper surface of the cover portion 400 and detachable from the diaper pad. Detachable portion 404 may be formed of a Velcro portion. The Velcro portion 404 is formed of Velcro. The diaper pad having the conductive pattern is combined with the urine detection device through the Velcro part 404 .

The urine detection device of the present invention is coupled to a diaper pad through a clip between the upper housing 300 and the cover 400 . When such a clip coupling is fastened with an outer diaper having relatively strong bearing capacity (shape retention force), the urine and feces detection device can be firmly coupled and the position can be maintained. However, in some cases, the clip connection may be fastened with an inner diaper having relatively weak bearing capacity (shape retention). In this case, the detachable part 404 described above is additionally coupled to the inner surface of the outer diaper so that the urine detection device can be firmly coupled and maintained in position.

An outer surface of the lower housing 100 may be covered with a silicon cover 110 . Specifically, the silicon cover part 110 formed to be larger than the lower housing 100 may cover at least a portion of the lower housing except for the open top. A recessed groove may be formed on a portion of a side surface of the lower housing 100 extending in the vertical direction. A part of the silicon cover part 110 corresponding to the recessed groove formed in the lower housing 100 may form a protruding pillar that can be combined with the recessed groove of the lower housing 100 . Accordingly, the silicon cover 110 is edge-coupled to the lower housing 100 . Preferably, when the silicon cover part 110 is coupled to the lower housing 100, it is formed to match the rim of the upper housing 300.

In addition, the first opening through which the HRM sensor unit 203 is exposed is formed in a pillar shape protruding downward from the lower surface of the lower housing 100 and is inserted into the silicon cover unit. Accordingly, the first opening may come into contact with the user's skin.

In addition, an inclined surface 310 may be formed in the fastening groove 303 . When the release button 402 is pressed, the fastening part 401 rises and moves along the inclined surface 310 . As the fastening part 401 rises and moves, the upper housing 300 and the cover part 400 are separated from each other. Through this, there is an advantage in that the cover part 400 can be more easily raised relative to the upper housing 300 by pressing the release button 402 .

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 6 .

A coupling portion may be additionally formed between the upper housing 300 and the cover portion 400 . The coupling part presses the diaper pad up and down between the upper housing 300 and the cover part 400 to more strongly couple the urine and feces detection device of the present invention with the diaper pad.

Specifically, the coupling part may be formed in a protrusion or groove structure formed between the upper housing 300 and the cover part 400 . 6 shows that a pillar portion 305 protruding from the upper housing 300 is formed by such a coupling portion. The pillar part 305 is formed as a straight pillar protruding upward from the upper housing 300 . Specifically, it is formed on the upper surface adjacent to the elastic member 301 connecting the upper housing 300 and the cover part 400 . A recessed groove may be formed on the lower surface of the cover part 400 to correspond to the pillar part 305 recessed into the inside.
