AI Technical Summary
In existing technologies, the success rate of stool detection is low when urine is present in diapers, especially when urine is urinated before defecation. It is difficult to detect stool in time, which may lead to the inability to change diapers in time and potentially cause incontinence dermatitis.
The air inlet of the stool detection sensor is positioned on the side of the absorbent part, away from the center line of the absorbent part along its length, in the width direction of the diaper. This optimizes the sensor's position, improves the detection effect of the gas sensor, and reduces the obstruction of gas diffusion caused by the expansion of the absorbent part.
It improves the success rate of stool detection when urine is present in diapers, ensuring timely detection of stool when both stool and urine are present, and reducing the risk of skin damage.

TECHNICAL FIELD
[0001] The present application relates to the technical field of excrement detection of human and animals, and particularly relates to a detection system for improving the detection success rate of feces when urine exists in a diaper. BACKGROUND
[0002] People with urinary and fecal incontinence, such as infants and patients, need to wear diapers. When the diaper user urinates, the urine has little effect on the diaper user because the diaper can absorb the urine, and the need to replace the diaper is not particularly urgent. However, when the diaper user defecates, the feces cannot be absorbed by the diaper, and if the diaper is not replaced in time after defecation, the feces will be in contact with the skin for a long time and cause damage to the skin, resulting in incontinence dermatitis (commonly known as "red buttocks"), so the diaper should be replaced in time after defecation.
[0003] In order to be able to determine whether there is feces in the diaper so that the nursing staff can timely perform corresponding processing, many technical solutions for detecting feces have appeared in the prior art.
[0004] For example, as shown in the US patent application with publication number US20120109087A1, a urine and feces detection device 110 is disclosed for being arranged on the outer surface of a diaper 20 to detect whether there is urine and feces in the diaper 20, and to provide a sound, visible, wireless or vibration signal to the user of the diaper 20 to indicate the presence of urine and feces. The signal device 110 includes a housing 135, a sensor 120 and an electronic circuit for detecting whether there is urine and feces in the diaper 20. Among them, the sensor 120 can include an electronic nose sensor 240, which is a sensor capable of detecting volatile gases, such as a hydrogen sulfide sensor, an ammonia sensor, a skatole sensor, an indole sensor or other suitable sensors, and the type of excrement can be determined according to the type of detected gas. Figure 1 As shown in the US patent application with publication number US20180253957A1, a diaper detection device is disclosed, which includes a diaper 900 and a detection device 201 attached to the outer surface of the diaper. The detection device 201 can have one or more sensors, such as a feces sensor for detecting feces and a urine sensor for detecting urine. The detection device 201 can be configured to send a wireless signal to a computer device when the humidity or gas concentration increases, or when the rate of change of humidity or gas concentration increases, thereby detecting whether there is excrement in the diaper and distinguishing the type of excrement.
[0005] Figure 2 As shown in the US patent application with publication number US20180253957A1, a diaper detection device is disclosed, which includes a diaper 900 and a detection device 201 attached to the outer surface of the diaper. The detection device 201 can have one or more sensors, such as a feces sensor for detecting feces and a urine sensor for detecting urine. The detection device 201 can be configured to send a wireless signal to a computer device when the humidity or gas concentration increases, or when the rate of change of humidity or gas concentration increases, thereby detecting whether there is excrement in the diaper and distinguishing the type of excrement.
[0006] As shown in the US patent application with publication number US20180253957A1, a diaper detection device is disclosed, which includes a diaper 900 and a detection device 201 attached to the outer surface of the diaper. The detection device 201 can have one or more sensors, such as a feces sensor for detecting feces and a urine sensor for detecting urine. The detection device 201 can be configured to send a wireless signal to a computer device when the humidity or gas concentration increases, or when the rate of change of humidity or gas concentration increases, thereby detecting whether there is excrement in the diaper and distinguishing the type of excrement. Figure 3 As shown, the Chinese patent application with publication number CN119214865A discloses a excrement detection system, which comprises a diaper 10 and an excrement detection device 20a; the diaper 10 comprises a main body 11 and a containing bag 13 arranged on the outer surface 111 of the main body 11, and a containing space 132 is formed between the containing bag 13 and the main body 11; the excrement detection device 20a comprises a urination sensor for detecting urination and a defecation sensor for detecting defecation; in use, the excrement detection device 20a is placed in the containing space 132, and whether there is excrement in the diaper and the type of the excrement can be detected through the urination sensor and the defecation sensor, and a corresponding alarm signal is sent to remind the nursing staff.
[0007] However, in the above prior art, the situation of the simultaneous existence of defecation and urination is not considered, or the influence of urination on defecation detection is not considered, especially the situation of urination first and then defecation. The present research finds that when there is urination, the detection sensitivity of defecation is low, and the defecation cannot be detected in time and the corresponding prompt is sent, and even the defecation may not be detected.

[0011] The absorption part has a length direction and a width direction, and the absorption part comprises a first side edge and a second side edge arranged opposite to each other in the width direction.
[0012] The detection device comprises a defecation detection sensor and a processor, the processor is electrically connected with the defecation detection sensor, the defecation detection sensor has an air inlet; the defecation detection sensor is arranged on the outer surface of the diaper, and the center of the air inlet of the defecation detection sensor is away from the center line of the length direction of the absorption part and close to the first side edge of the absorption part in the width direction.
[0013] In an optional embodiment of the present application, the center of the air inlet of the defecation detection sensor is located on the first side edge; or
[0014] The excrement detection sensor is arranged on the outer surface of the absorbing part, and a center of an air inlet of the excrement detection sensor is spaced apart from the first side edge.
[0015] In an optional embodiment of the present application, the diaper further comprises a first side wing made of a flexible material, the first side wing being connected to part or all of the first side edge of the absorbing part and extending away from the absorbing part.
[0016] In an optional embodiment of the present application, a center of an air inlet of the excrement detection sensor is arranged on the first side edge; or
[0017] A center of an air inlet of the excrement detection sensor is arranged on the outer surface of the absorbing part; or
[0018] A center of an air inlet of the excrement detection sensor is arranged on the first side wing.
[0019] In an optional embodiment of the present application, the first side wing is made of a breathable material as a whole; or
[0020] The first side wing is made of a breathable material at a position close to or for mounting the excrement detection sensor.
[0021] In an optional embodiment of the present application, the diaper further comprises a urine detection sensor arranged on the diaper, and the urine detection sensor is electrically connected to the processor.
[0022] In an optional embodiment of the present application, the urine detection sensor is arranged on the outer surface of the absorbing part, and the urine detection sensor comprises a humidity sensor.
[0023] In an optional embodiment of the present application, the excrement detection sensor comprises a first excrement detection sensor and a second excrement detection sensor;
[0024] A center of an air inlet of the first excrement detection sensor is arranged on the first side edge away from a center line of the length direction of the absorbing part in the width direction, and a center of an air inlet of the second excrement detection sensor is arranged on the second side edge away from the center line of the length direction of the absorbing part in the width direction; or

[0030] Beneficial effects: In this embodiment, the center of the air inlet of the stool detection sensor is located away from the centerline of the absorption part in the width direction and closer to the first side of the absorption part. In this way, after the diaper absorbs water and expands, since the area near the centerline is thicker than the area near the first side, placing the center of the air inlet of the stool detection sensor near the first side allows more gas emitted by the stool to pass through the absorption part and enter the stool detection sensor (like a gas sensor) than placing it near the centerline. This results in better detection. Furthermore, the volatile gases produced by the stool will leak out from the two edges of the absorption part (the edges where the first and second sides are located) and be detected by the stool detection sensor. This solves the problem in the prior art where the stool sensors are all located in the middle or near the middle of the outer surface of the diaper, resulting in situations where stool and urine are present simultaneously, especially when urine is urinated before stool, the stool cannot be detected or cannot be detected in a timely manner.

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0056] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0057] The inventors discovered through research that, since both the urinary and fecal excretion openings of the human body are located along the midline, in existing technologies, when using diapers, the urine and fecal detection sensors are naturally positioned on the midline of the diaper (corresponding to the center line L1 of the absorption section 11 described below). This ensures that the moisture from excreted urine and the odorous gases from excreted feces are closest to the sensor. In other words, apart from positional deviations caused by installation errors, mounting the urine and fecal detection sensors on the midline of the diaper is the most conceivable approach or a conventional technical method in existing technologies. Experimental testing by the inventors confirmed that when only feces are present, gas sensors for detecting feces (such as VOC sensors, ammonia sensors, hydrogen sulfide sensors, etc.) are more likely to detect fecal gas signals when positioned on the midline of the diaper than when positioned away from the midline. However, when urine is present simultaneously or when urine precedes feces, the gas sensors for detecting feces have difficulty detecting the fecal signal. Analysis revealed that during urination, especially when urination precedes defecation, the urine is absorbed by the absorbent material in the diaper. This absorbent material expands, particularly along the midline of the body, creating a structure that is thicker in the middle and thinner at the edges. This expansion acts like a gas barrier, hindering the flow and diffusion of volatile gases produced by feces. Consequently, these gases cannot pass through the wet diaper to reach the gas sensor, making it difficult for the gas sensor to detect feces effectively and promptly, and sometimes even resulting in the sensor failing to detect feces at all.
[0058] To address the above technical problems, this embodiment provides a detection system that improves the success rate of detecting feces in diapers when urine is present. For example... Figures 4-16As shown, the detection system for improving the success rate of stool detection when urine is present in a diaper includes a diaper 10 and a detection device 20. The diaper 10 includes an absorbent part 11 and a fixing part 12. The fixing part 12 is used to fix the absorbent part 11 near the excretion opening of the diaper user. The absorbent part 11 contains absorbent material and has a length direction F1 and a width direction F2. The absorbent part 11 includes a first side 11c and a second side 11d disposed opposite each other in its width direction F2. The detection device 20 includes a large... A stool detection sensor 21 and a processor 23 are provided. The processor 23 is electrically connected to the stool detection sensor 21, which has an air inlet. The stool detection sensor 21 is disposed on the outer surface 10f of the diaper 10, and the center of the air inlet of the stool detection sensor 21 is located away from the center line L1 of the absorbent part 11 in the width direction F2 and closer to the first side 11c of the absorbent part 11 than to the center line L1. In a specific embodiment, the distance between the center of the air inlet of the stool detection sensor 21 and the center line L1 is at least half the distance between the center of the air inlet of the stool detection sensor 21 and the first side 11c. The distance between the center of the air inlet of the feces detection sensor 21 and the center line L1 is the distance between the center of the air inlet of the feces detection sensor 21 and the nearest point on the center line L1. The distance between the center of the air inlet of the feces detection sensor 21 and the first side 11c is the distance to the nearest point on the first side 11c.
[0059] The assembly of the feces detection sensor 21 may contain errors. In existing technologies, due to assembly errors, the center of the air inlet of the feces sensor 21 will only slightly deviate from the center line L1 and be closer to the first side 11c. This differs from the present technical solution, where, to improve the success rate of feces detection when urine is present in the diaper, the center of the air inlet of the feces detection sensor 21 is intentionally set to be away from the center line L1 of the absorption part 11 in the width direction F2 and closer to the first side 11c of the absorption part 11 in the length direction F1. It should be noted that errors exist in the actual manufacturing process of the diaper 10 and the assembly process of the feces detection sensor 21. For example, the assembly error under existing technical means will not exceed ±5mm. Within the corresponding error range, it indicates that the product manufacturing and assembly are qualified; outside the corresponding error range, it indicates that the product manufacturing and assembly are unqualified.
[0060] The center line L1 is a virtual line on the absorbent part 11, extending in the same direction as the length direction F1 of the absorbent part 11. The first side 11c and the second side 11d are symmetrical along the center line L1, which divides the absorbent part 11 into two equal parts. The center line L1 can also be regarded as the center line of the diaper 10.
[0061] It is understood that the first side 11c and the second side 11d can be interchanged. That is, the first side 11c, which is located in the width direction F2 of the absorption part 11 away from the center line L1 of the length direction F1 and close to the absorption part 11, can be replaced with the second side 11d, which is located in the width direction F2 of the absorption part 11 away from the center line L1 of the length direction F1 and close to the absorption part 11. In other words, this embodiment includes either the first side 11c or the second side 11d, which is located in the width direction F2 of the absorption part 11 away from the center line L1 of the length direction F1 and close to the absorption part 11. Alternatively, when the diaper 10 is placed on the human body, the side of the absorbent part 11 of the diaper 10 that is closer to the left side of the human body can be defined as the first side 11c and the other side as the second side 11d. Alternatively, the side of the absorbent part 11 of the diaper 10 that is closer to the right side of the human body can be defined as the first side 11c and the other side as the second side 11d.
[0062] The length direction of the absorption section 11 can be referenced. Figure 5 , Figure 7 and Figure 14 The F1 marked in the figure is the length direction F1 of the lower absorbent part 11 of the diaper 10 in the unfolded state.
[0063] The width direction of the absorption section 11 can be referenced. Figure 5 , Figure 7 and Figure 14 The F2 marked in the diagram refers to the width direction of the lower absorbent portion 11 when the diaper is in the unfolded state. It should be noted that the diaper 10 can also display the width direction of the absorbent portion 11 in other states, such as when the diaper 10 is in a certain position. Figure 4 , Figure 6 , Figures 8-13 F1 is marked in one of the usage states.
[0064] In this embodiment, the center of the air inlet of the stool detection sensor 21 is located away from the center line L1 of the length direction F1 of the absorption part 11 in the width direction F2, but closer to the first side 11c of the absorption part 11. This way, after the diaper absorbs water and expands, since the area near the center line L1 is thicker than the area near the first side 11c, placing the center of the air inlet of the stool detection sensor 21 near the first side 11c allows more gas emitted from the stool to pass through the absorption part 11 and enter the stool detection sensor than placing it near the center line L1. If the device 21 is a gas sensor, the detection effect will be better. Also, the volatile gases produced by feces will leak from the two side edges of the absorption part 11 (the edges where the first side 11c and the second side 11d are located) and be detected by the feces detection sensor 21. This solves the problem in the prior art where the feces detection sensors are all located in the middle or near the middle of the outer surface of the diaper, resulting in the situation where feces and urine are present at the same time, especially when urine is urinated first and then feces are urinated, and therefore feces cannot be detected or cannot be detected in time.
[0065] like Figure 5 , Figure 7 and Figure 14 As shown, the absorption section 11 has a sheet-like structure. Figures 4-15 As shown, the length of the absorbent portion 11 is greater than its width, and its width is greater than its thickness. The absorbent portion 11 has a first end 11a and a second end 11b disposed opposite each other in the length direction F1, a first side 11c and a second side 11d disposed opposite each other in the width direction F2, and an inner surface 11e and an outer surface 11f disposed opposite each other. When the diaper 10 is placed on the human body, the inner surface 11e of the absorbent portion 11 faces the excretion opening of the human body.
[0066] One embodiment, such as Figures 4-12As shown, the fixing part 12 is connected to the first end 11a and the second end 11b of the absorbent part 11. Specifically, the fixing part 12 includes a front fixing part 121 and a rear fixing part 122. The front fixing part 121 is connected to the first end 11a, and the rear fixing part 122 is connected to the second end 11b. When the diaper 10 is used on the human body, the absorbent part 11 wraps around the lower abdomen, crotch, and buttocks. The front fixing part 121 is located on the abdomen, and the rear fixing part 122 is located on the waist. The fixing part 12 also includes a fixing strap 123, which is used to fix the front fixing part 121 and the rear fixing part 122 together to form a ring-shaped structure around the waist and abdomen of the diaper user, so as to stably fix the absorbent part 11 to the lower abdomen, crotch, and buttocks of the diaper user. Therefore, the absorbent part 11 forms a curved structure with an inner receiving space. When the diaper user urinates, the urine is absorbed by the absorbent part 11; when the diaper user defecates, the feces are contained within the receiving space. Specifically, the front fixing part 121 and the rear fixing part 122 can be made of elastic material to improve the comfort of the diaper user; the fixing strap 123 can be Velcro to improve the ease of putting on and changing diapers.
[0067] Another embodiment, such as Figure 13 and Figure 14As shown, the fixing part 12 is connected to both ends of the first side 11c and both ends of the second side 11d. Specifically, the fixing part 12 includes a first front fixing part 121a, a second front fixing part 121b, a first rear fixing part 122a, and a second rear fixing part 122b. The first front fixing part 121a is connected to one end of the first side 11c, the first rear fixing part 122a is connected to the other end of the first side 11c, the second front fixing part 121b is connected to one end of the second side 11d, and the second rear fixing part 122b is connected to the other end of the second side 11d. The first front fixing part 121a and the second front fixing part 121b are spaced apart in the width direction F2 of the absorption part 11, the first rear fixing part 122a and the second rear fixing part 122b are spaced apart in the width direction F2 of the absorption part 11, the first front fixing part 121a and the first rear fixing part 122a are spaced apart in the length direction F1 of the absorption part 11, and the second front fixing part 121b and the second rear fixing part 122b are spaced apart in the length direction F1 of the absorption part 11. The fixing part 12 also includes a fixing strap 123, which is used to fix the first front fixing part 121a, the second front fixing part 121b, the first rear fixing part 122a and the second rear fixing part 122b together, so that the first front fixing part 121a, the second front fixing part 121b, the first rear fixing part 122a and the second rear fixing part 122b and the two ends of the absorbent part 11 together form a ring-shaped structure around the waist and abdomen of the diaper user, so as to stably fix the absorbent part 11 to the lower abdomen, crotch and buttocks of the diaper user.
[0068] For example, a receiving bag 14 is provided on the diaper 10 at the position for setting the stool detection sensor 21. The receiving bag 14 has a receiving space 142 for receiving the stool detection sensor 21. The stool detection sensor 21 can be placed in the receiving space 142 to realize the stool detection sensor 21 being set on the diaper 10. It should be noted that the way the stool detection sensor 21 is set on the diaper 10 is not limited to this, and other methods can also be used. In other embodiments, the stool detection sensor 21 can also be fixed by other methods such as adhesive, magnetic attraction, etc. The stool detection sensor 21 can also be set on the absorbent part 11, such as at the position near the first side 11c or the second side 11d on the outer surface 11f of the absorbent part 11.
[0069] In one embodiment, the fecal detection sensor 21 can be disposed together with other components of the detection device 20, such as the processor 23, within the same receiving space 142 of the receiving bag 14; in another embodiment, the fecal detection sensor 21 can be disposed in a different location from other components of the detection device 20, such as the processor 23. Further illustrative examples will be provided below with reference to other accompanying drawings. It should be noted that if the entire detection device 20 is disposed within the receiving space 142 near the first side 11c or the second side 11d of the absorption section 11, the large size of the detection device 20 may affect the user's movement, thus impacting comfort. Therefore, in an optional embodiment, the fecal detection sensor 21 can be disposed within the receiving space 142 near the first side 11c or the second side 11d of the absorption section 11, while the other parts of the detection device 20 are disposed in other locations.
[0070] One embodiment, such as Figure 4 and Figure 5 As shown, a fecal detection sensor 21 is disposed on the outer surface 11f of the absorption section 11. A gap is formed between the center of the air inlet of the fecal detection sensor 21 and the first side 11c. The center of the air inlet of the fecal detection sensor 21 is located away from the center line L1 of the length direction F1 of the absorption section 11 in the width direction F2 and close to the first side 11c of the absorption section 11. For example, a container bag 14 is disposed on the outer surface 11f of the absorption section 11 and spaced apart from the first side 11c. The container bag 14 is located away from the center line L1 of the length direction F1 of the absorption section 11 in the width direction F2 and close to the first side 11c of the absorption section 11. The fecal detection sensor 21 is disposed inside the container bag 14.
[0071] In another embodiment, not shown in the figure, the center of the air inlet of the feces detection sensor 21 is located on the first side 11c. For example, the receiving bag 14 is located at the position of the first side 11c, and the feces detection sensor 21 is located inside the receiving bag 14 located at the position of the first side 11c.
[0072] Therefore, the outer surface 10f of the diaper 10 may include the outer surface 11f of the absorbent portion 11, the first side 11c, and the second side 11d.
[0073] The absorbent portion 11 includes a first part 111, a second part 112, and a third part 113 connected end to end. When the diaper 10 is used on the human body, the first part 111 covers the lower abdomen, the second part 112 covers the groin area, and the third part 113 covers the buttocks. The human body's defecation opening is located in the groin area; therefore, when the body defecates, the feces are located inside the second part 112 covering the groin area. To improve detection sensitivity, the feces detection sensor 21 should be close to the location of the feces. One embodiment, such as... Figure 4 ,Figure 5 , Figure 13 and Figure 14 As shown, a fecal detection sensor 21 is disposed in the first portion 111, and the distance between the center of the air inlet of the fecal detection sensor 21 and the second portion 112 is less than the distance between the center of the air inlet of the fecal detection sensor 21 and the end of the first portion 111 furthest from the second portion 112. In another embodiment, not shown in the figure, the fecal detection sensor 21 is disposed in the second portion 112. In yet another embodiment, not shown in the figure, the fecal detection sensor 21 is disposed in the third portion 113, and the distance between the center of the air inlet of the fecal detection sensor 21 and the second portion 112 is less than the distance between the center of the air inlet of the fecal detection sensor 21 and the end of the third portion 113 furthest from the second portion 112.
[0074] The stool detection sensor 21 can be disposed on the outer surface 11f of the absorbent portion 11. The above embodiments of this application exemplify this by showing the stool detection sensor 21 disposed on the outer surface 11f of the absorbent portion 11. It is understood that the location of the stool detection sensor 21 is not limited to the outer surface 11f of the absorbent portion 11; for example, the stool detection sensor 21 could be disposed on the side wing of the diaper 10. Figures 6-12 As shown, the diaper 10 also includes a first side wing 13c and a second side wing 13d made of flexible material. The first side wing 13c is partially or completely connected to the first side 11c of the absorbent portion 11 and extends in a direction away from the absorbent portion 11. The second side wing 13d is partially or completely connected to the second side 11d of the absorbent portion 11 and extends in a direction away from the absorbent portion 11. For example, the first side wing 13c and the second side wing 13d are located on both sides of the absorbent portion 11. Neither the first side wing 13c nor the second side wing 13d contains absorbent material. When the diaper 10 is used on a person, the first side wing 13c and the second side wing 13d can fit snugly against the legs of the person. When the amount of urine is large, the first side wing 13c and the second side wing 13d can prevent urine from overflowing. A stool detection sensor 21 can be disposed on the first side wing 13c or the second side wing 13d. To facilitate fixing the fecal detection sensor 21, a receiving bag 14 adapted to the volume of the fecal detection sensor 21 can be provided on the first side wing 13c or the second side wing 13d. That is, the receiving bag 14 is provided on the first side wing 13c or the second side wing 13d.
[0075] To reduce the impact of the first side wing 13c and the second side wing 13d on stool detection, the first side wing 13c and the second side wing 13d are made of a breathable material, such as non-woven fabric. In one embodiment, the first side wing 13c and the second side wing 13d are entirely made of a breathable material. In another embodiment, the portion of the first side wing 13c used for mounting or proximity to the stool detection sensor 21 is made of a breathable material. It is understood that when the stool detection sensor 21 is mounted on the second side wing 13d, the portion of the second side wing 13d used for mounting or proximity to the stool detection sensor 21 is made of a breathable material.
[0076] One embodiment, such as Figure 6 and Figure 7 As shown, the center of the air inlet of the feces detection sensor 21 is located on the first side wing 13c, and not on the absorption section 11. Another embodiment, as... Figure 8 As shown, the center of the air inlet of the feces detection sensor 21 is located on the first side 11c. Another embodiment, as... Figure 9 As shown, the center of the air inlet of the stool detection sensor 21 is located on the outer surface 11f of the absorbent part 11 and not on the first side wing 13c. Therefore, the outer surface 10f of the diaper 10 may include the outer surface 11f of the absorbent part 11, the first side 11c, the second side 11d, and the first side wing 13c and the second side wing 13d.
[0077] When at least a portion of the feces detection sensor 21 is disposed on the first side wing 13c, in order to bring the feces detection sensor 21 closer to the feces located inside the second portion 112 of the absorption section 11 and improve the sensitivity of feces detection, the feces detection sensor 21 can be disposed at different positions on the first side wing 13c as needed. Specifically, for example... Figures 6-8 As shown, the first side wing 13c includes a first region 13c1 adjacent to the first portion 111 of the absorption section 11, a second region 13c2 adjacent to the second portion 112 of the absorption section 11, and a third region 13c3 adjacent to the third portion 113 of the absorption section 11. In one embodiment, a fecal detection sensor 21 is disposed in the first region 13c1, and the distance between the center of the air inlet of the fecal detection sensor 21 and the second portion 112 is less than the distance between the center of the air inlet of the fecal detection sensor 21 and the end of the first portion 111 away from the second portion 112. In another embodiment, as... Figure 10 As shown, the feces detection sensor 21 is disposed in the second region 13c2. In another embodiment, not shown in the figure, the feces detection sensor 21 is disposed in the third region 13c3, and the distance between the center of the air inlet of the feces detection sensor 21 and the second part 112 is less than the distance between the center of the air inlet of the feces detection sensor 21 and the end of the third part 113 away from the second part 112.
[0078] To improve the reliability of stool detection, multiple stool detection sensors 21 can be set. For example, such as... Figure 17 As shown, the stool detection sensor 21 includes a first stool detection sensor 21a and a second stool detection sensor 21b, which are disposed at different positions on the diaper 10. For example, the first stool detection sensor 21a and the second stool detection sensor 21b may be disposed at different positions on the absorbent part 11, or the first stool detection sensor 21a and the second stool detection sensor 21b may be disposed on the first side wing 13c and the second side wing 13d, respectively.
[0079] During the use of the diaper 10, if there is feces in the diaper 10, corresponding volatile gases will overflow from both sides of the diaper 10. Therefore, feces detection sensors 21 can be installed at corresponding positions on both sides of the diaper 10. In one embodiment, the center of the air inlet of the first feces detection sensor 21a is located away from the center line L1 of the length direction F1 of the absorption part 11 in the width direction F2 and close to the first side 11c of the absorption part 11, and the center of the air inlet of the second feces detection sensor 21b is located away from the center line L1 of the length direction F1 of the absorption part 11 in the width direction F2 and close to the second side 11d of the absorption part 11. An optional embodiment, such as... Figure 11 As shown, the diaper 10 includes two receiving bags, namely a first receiving bag 14a and a second receiving bag 14b. The first receiving bag 14a has a first receiving space 142a for receiving a first stool detection sensor 21a, and the second receiving bag 14b has a second receiving space 142b for receiving a second stool detection sensor 21b. The first stool detection sensor 21a is disposed in the first receiving space 142a, and the second stool detection sensor 21b is disposed in the second receiving space 142b. In one configuration, the first receiving bag 14a is disposed on the first side wing 13c, and the second receiving bag 14b is disposed on the second side wing 13d. In another configuration, the first receiving bag 14a is disposed on the first side 11c, and the second receiving bag 14b is disposed on the second side 11d. In yet another configuration, both the first receiving bag 14a and the second receiving bag 14b are disposed on the outer surface 11f of the absorbent portion 11.
[0080] When only feces are present in the diaper 10 and no urine is present, the absorbent material in the absorbent section 11 that has not absorbed urine has little obstruction to the volatile gases produced by the feces. Furthermore, the middle position of the outer surface of the absorbent section 11 of the diaper 10 is closest to the feces. Therefore, if the feces detection sensor 21 is positioned at the middle position of the outer surface of the diaper 10, a higher feces detection sensitivity can be obtained. Thus, in order to accommodate both the simultaneous presence of feces and urine in the diaper, and the presence of only feces in the diaper, in another embodiment, the center of the air inlet of the first feces detection sensor 21a is located away from the center line L1 of the length direction F1 of the absorbent section 11 in the width direction F2 and close to the first side 11c of the absorbent section 11, and the center of the air inlet of the second feces detection sensor 21b is located on the center line L1 of the length direction F1 of the absorbent section 11. Specifically, an optional embodiment, such as... Figure 12 As shown, the diaper 10 includes two receiving bags, namely a first receiving bag 14a and a second receiving bag 14b. The first receiving bag 14a has a first receiving space 142a for receiving a first stool detection sensor 21a, and the second receiving bag 14b has a second receiving space 142b for receiving a second stool detection sensor 21b. The first stool detection sensor 21a is disposed in the first receiving space 142a, and the second stool detection sensor 21b is disposed in the second receiving space 142b. In one configuration, the first receiving bag 14a is disposed on the first side wing 13c, and the second receiving bag 14b is disposed on the center line L1 of the outer surface 11f of the absorbent part 11. In another configuration, the first receiving bag 14a is disposed on the first side 11c of the absorbent part 11, and the second receiving bag 14b is disposed on the center line L1 of the outer surface 11f of the absorbent part 11. In another scenario, both the first receiving bag 14a and the second receiving bag 14b are disposed on the outer surface 11f of the absorbent portion 11. For example, the first receiving bag 14a is disposed near the first side 11c, and the second receiving bag 14b is disposed on the center line L1 along the length direction F1. It is understood that the first stool detection sensor 21a and the second stool detection sensor 21b can be disposed on the diaper 10 in other ways.
[0081] It should be noted that, in the case of the detection device 20 of this application including a first stool detection sensor 21a and a second stool detection sensor 21b, the detection device 20 can be one or two. When there is one detection device 20, the first stool detection sensor 21a and the second stool detection sensor 21b are arranged separately. When there are two detection devices 20, each detection device 20 includes one stool detection sensor.
[0082] For example, the feces detection sensor 21 includes a gas sensor, such as a hydrogen sulfide sensor, a VOC sensor, or other sensor capable of detecting volatile gases produced by feces.
[0083] like Figure 16 and Figure 17 As shown, the detection device 20 also includes a urine detection sensor 22 disposed on the diaper 10, and the urine detection sensor 22 is electrically connected to the processor 23. Exemplarily, the urine detection sensor 22 is disposed on the outer surface 11f of the absorption section 11, and the urine detection sensor 22 includes a humidity sensor. In one embodiment, the urine detection sensor 22 and the feces detection sensor 21 are disposed together in the same position on the diaper 10, for example, within the same receiving bag 14. In another embodiment, the urine detection sensor 22 and the feces detection sensor 21 are disposed in different positions on the diaper 10. The urine detection sensor 22 can be disposed at any position on the diaper 10 as needed; the embodiments of this application do not limit the placement position of the urine detection sensor 22.
[0084] In order to alert caregivers when urination or defecation is detected, in this embodiment, such as Figure 16 and Figure 17 As shown, the detection device 20 also includes a communication module 24 electrically connected to the processor 23. The communication module 24 is used to communicate with an external terminal device 30 (such as a mobile phone, computer, etc.). When the processor 23 detects feces through the feces detection sensor 21 (e.g., a gas sensor) and / or detects urine through the urine detection sensor 22 (e.g., a humidity sensor), the communication module 24 sends a corresponding alarm signal to the external terminal device 30, which then issues a corresponding reminder to the caregiver. For example, when the processor 23 detects feces through the feces detection sensor 21, it sends a feces alarm signal to the external terminal device 30 through the communication module 24, and the external terminal device 30 issues a feces reminder to the caregiver upon receiving the feces alarm signal; similarly, when the processor 23 detects urine through the urine detection sensor 22, it sends a urine alarm signal to the external terminal device 30 through the communication module 24, and the external terminal device 30 issues a urine reminder to the caregiver upon receiving the urine alarm signal. External terminal device 30 can issue reminders through vibration, sound, text, etc., and can distinguish between urination and defecation by different frequencies of vibration, different sounds, and different text. In other embodiments, communication module 24 can be replaced with an alarm, with processor 23 directly electrically connected to the alarm. When processor 23 detects urination or defecation, it controls the alarm to issue a corresponding alarm to remind caregivers.
[0085] <Experimental Data>
[0086] To verify the technical effectiveness of this solution, the following experiment was conducted.
[0087] Because feces emit a variety of gases with complex compositions, including H2S and volatile organic compounds (VOCs), it is difficult to directly obtain fecal gases. Therefore, it is possible to use sensors that are sensitive to these gases for testing, such as sensors sensitive to H2S or sensors sensitive to VOCs.
[0088] In this experiment, three locations, P1-P3, were set up for installing the stool detection sensor. The first location, P1, is situated on the diaper near the first side edge 11c; this first location, P1, is the location specified in this application. Figure 6 In the corresponding embodiment, the fecal detection sensor 21 is positioned on the first side wing 13c. When the fecal detection sensor is positioned at the first position P1, the center of its air inlet is located on the first side wing 13c. The second position P2 is located on the center line L1 along the length direction F1 of the absorption section 11, and is on the first part 111 of the absorption section 11, close to the second part 112. The second position P2 is the same as the fecal detection sensor 21 in the prior art. When the fecal detection sensor is positioned at the second position P2, the center of its air inlet is located on the center line L1. The third position P3 is located on the center line L1 along the length direction F1 of the absorption section 11, and is on the first part 111 of the absorption section 11, away from the second part 112. When the fecal detection sensor is positioned at the third position P3, the center of its air inlet is located on the center line L1. Specifically, the first position P1, the second position P2, and the third position P3 are all provided with receiving bags, and each sensor is placed in the corresponding receiving bag.
[0089] Experiment 1
[0090] A VOC sensor sensitive to VOC gas emitted from feces was used as the fecal detection sensor 21 for testing. There are many such sensors on the market. At the same time, such sensors are also sensitive to alcohol gas. Therefore, alcohol gas can be used to simulate fecal gas for testing. When such a sensor detects alcohol gas, the signal will increase, and the signal range is 0-4095.
[0091] S11; Place the diaper 10 on a 1-meter-tall child mannequin. Install a stool detection sensor 21 and a urine detection sensor 22 at the third position P3, the second position P2, and the first position P1 on the outer surface of the diaper 10. The urine detection sensor 22 is a humidity sensor. The locations are as follows: Figure 15 As shown;
[0092] S12: Obtain the initial values of the gas sensor and the humidity sensor located at the third position P3, the second position P2 and the first position P1;
[0093] S13: Place a tissue soaked in an alcohol solution of a certain concentration (which will emit about 0.2 mg / L of alcohol gas at 34 degrees Celsius) into the crotch area of the human body model inside the diaper 10 to simulate the situation of having defecation but not urination.
[0094] S14: After a preset time of 10 minutes, acquire the detection values of the gas sensor located at the third position P3, the second position P2, and the first position P1, as well as the detection value of the humidity sensor.
[0095] S15: Using a syringe, inject 100 ml of 34-degree Celsius pure water into diaper 10 within 1 minute through a silicone tube with an output port fixed to the crotch of the human body model, to simulate the situation where urination occurs simultaneously.
[0096] S16: After a preset time of 20 minutes, acquire the detection values of the gas sensor located at the third position P3, the second position P2, and the first position P1, as well as the detection value of the humidity sensor.
[0097] The experimental data obtained in Experiment 1 are shown in Table 1 below:
[0098] Table 1
[0099]
[0100] The differences in each item in the table are the differences between their measured values and the initial values of the paper towels before the alcohol solution was added.
[0101] From the data of Experiment 1 above, we can see that:
[0102] (1) When only feces are present: After adding alcohol solution to the tissue for 10 minutes, the detection values of the sensors at the second position P2 and the first position P1 of the diaper 10 increased significantly compared to before adding alcohol solution to the tissue. The increase in the detection value of the sensor at the second position P2 of the diaper 10 was particularly significant. This indicates that when only feces are present, setting the sensor at the second position P2 and the first position P1 of the diaper 10 can detect the feces in the diaper 10 in a timely and effective manner, especially when it is at the second position P2. However, the detection value of the sensor at the third position P3 of the diaper 10 did not increase significantly, indicating that when only feces are present, setting the sensor at the third position P3 of the diaper 10 cannot detect the feces in the diaper 10 in a timely and effective manner.
[0103] (2) When both feces and urine are present: After adding water to the diaper 10 for 20 minutes, the detection value of the sensor at the first position P1 of the diaper 10 is significantly higher than that before adding alcohol solution to the paper towel. This indicates that when both feces and urine are present, setting the sensor at the first position P1 of the diaper 10 can detect feces in the diaper 10 in a timely and effective manner. However, the detection values of the sensors at the third position P3 and the second position P2 of the diaper 10 are not significantly higher. Therefore, when both feces and urine are present, setting the sensors at the third position P3 and the second position P2 of the diaper 10 cannot detect feces in the diaper 10 in a timely and effective manner.
[0104] <Experiment 2>
[0105] An H2S sensor sensitive to H2S gas emitted by feces was used as the feces detection sensor 21 for testing. There are many such sensors on the market. Therefore, H2S gas can be used to simulate fecal gas for testing. When such a sensor detects H2S gas, the signal will increase, and the signal range is 0-4095.
[0106] S21; Place the diaper 10 on a 1-meter-tall child mannequin, and place a feces detection sensor 21 (such as a gas sensor) and a urine detection sensor 22 (such as a humidity sensor) on the middle (second position P2) and left side (first position P1) of the outer surface of the diaper 10, respectively. Figure 15 As shown;
[0107] S22: Obtain the initial values of the gas sensor and the humidity sensor located at the second position P2 and the first position P1;
[0108] S23: Fix one end of a PTFE tube with an inner diameter of 4mm to the crotch of the human body model, and connect the other end to the output of the flow regulating valve. Introduce 50ppm H2S gas into the diaper 10 at a flow rate of 0.1L / min to simulate the situation of having defecation but not urination.
[0109] S24: After a preset time, such as 10 minutes, acquire the detection values of the gas sensor located at the second position P2 and the first position P1, as well as the detection value of the humidity sensor.
[0110] S25: Using a syringe, inject 200 ml of 34-degree Celsius pure water into diaper 10 within 1 minute through a silicone tube fixed to the crotch of the human body model through another outlet, in order to simulate the situation where feces and urine are present at the same time.
[0111] S26: After a preset time, such as 10 minutes, acquire the detection values of the gas sensor located at the second position P2 and the first position P1, as well as the detection value of the humidity sensor.
[0112] The experimental data obtained in Experiment 2 are shown in Table 2 below:
[0113] Table 2
[0114]
[0115] The differences in each item in Table 2 are the differences between the detected value and the initial value before H2S gas was introduced.
[0116] From the data in Experiment 2 above, we can see that:
[0117] (1) When only feces are present: After H2S gas was introduced into the diaper 10 for 10 minutes, the detection values of the sensors at the second position P2 and the first position P1 of the diaper 10 were significantly higher than before the H2S gas was introduced into the diaper 10. However, the value detected by the sensor at the second position P2 was slightly higher than that at the first position P1. This indicates that when only feces are present, setting the sensor at the second position P2 or the first position P1 of the diaper 10 can detect the feces in the diaper 10 in a timely and effective manner.
[0118] (2) When both feces and urine are present: After adding water to the diaper 10 for 10 minutes, compared with the initial value before H2S gas was introduced into the diaper 10, the detection values of the sensors at the second position P2 and the first position P1 of the diaper 10 are both improved. However, the detection value of the sensor at the first position P1 of the diaper 10 is improved more significantly. This indicates that when both feces and urine are present, setting the sensor at the second position P2 and the first position P1 of the diaper 10 can detect feces in the diaper. However, setting the sensor at the first position P1 of the diaper is more timely and effective in detecting feces in the diaper 10.
[0119] The above provides a detailed description of the detection system for improving the success rate of stool detection when urine is present in diapers, as provided in the embodiments of this application. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
