Description

Technical Field

[0001] The present application relates to the technical field of human and animal excrement detection, and in particular to a detection system for improving the success rate of feces detection when urine is present in a diaper. Background Art

[0002] People with incontinence, such as infants and patients, need to wear diapers. When diaper users urinate, the diaper can absorb the urine, so the urine has little impact on the diaper user, and the need to change diapers is not particularly urgent; when diaper users defecate, the feces cannot be absorbed by the diaper. If the diaper is not changed in time after defecation, the feces will contact the skin for a long time and cause damage to the skin, causing incontinence dermatitis (commonly known as "red buttocks"), so diapers should be changed in time after defecation.

[0003] In order to determine whether there is feces in the diaper so that the nursing staff can take corresponding measures in time, many technical solutions for detecting feces have appeared in the prior art.

[0004] For example, Figure 1 As shown, a defecation and urine detection device 110 is disclosed in the U.S. patent application with publication number US20120109087A1, which is used to be arranged on the outer surface of a diaper 20 to detect whether there is defecation and urine in the diaper 20, and provide a sound, visible, wireless or vibration signal to the user of the diaper 20 to indicate the presence of defecation and urine. The signal device 110 includes a housing 135, a sensor 120 and an electronic circuit for detecting whether there is defecation and urine in the diaper 20. Among them, the sensor 120 may include an electronic nose sensor 240, which is a sensor that can detect volatile gases, such as a hydrogen sulfide sensor, an ammonia sensor, a skatole sensor, an indole sensor or other suitable sensors, and can determine whether there is excrement and distinguish the type of excrement according to the different types of gases detected.

[0005] like Figure 2 As shown, the U.S. patent application with publication number US20180253957A1 discloses a diaper detection device, including a diaper 900 and a detection device 201 fixed to the outer surface of the diaper, and the detection device 201 may have one or more sensors, such as a stool sensor for detecting stool and a urine sensor for detecting urine. The detection device 201 may 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 the humidity or gas concentration increases, thereby detecting whether there is excrement in the diaper and distinguishing the type of excrement.

[0006] like Figure 3As shown, a Chinese patent application with publication number CN119214865A discloses an excrement detection system, including a diaper 10 and an excrement detection device 20a; the diaper 10 includes a main body 11 and a receiving bag 13 arranged on the outer surface 111 of the main body 11, and a receiving space 132 is formed between the receiving bag 13 and the main body 11; the excrement detection device 20a includes a urine sensor for detecting urine and a feces sensor for detecting feces. When in use, the excrement detection device 20a is placed in the receiving space 132, and the urine sensor and the feces sensor can be used to detect whether there is excrement in the diaper and the type of excrement, and a corresponding alarm signal is issued to remind the caregiver.

[0007] However, the above existing technologies do not consider the situation where defecation and urination exist at the same time, or do not consider the impact of urination on defecation detection, especially the situation where urination is excreted before defecation. This study found that when urination is present, the detection sensitivity of defecation is low and the defecation cannot be detected in time and the corresponding prompt cannot be issued, and it may even be possible that the defecation cannot be detected.

[0012] The detection device includes a stool detection sensor and a processor, the processor is electrically connected to the stool detection sensor, and the stool detection sensor has an air inlet; the stool detection sensor is arranged on the outer surface of the diaper, and the center of the air inlet of the stool detection sensor is away from the center line of the length direction of the absorption part in the width direction and close to the first side edge of the absorption part.

[0013] In an optional implementation manner of the present application, the center of the air inlet of the stool detection sensor is located on the first side; or

[0014] The stool detection sensor is disposed on the outer surface of the absorbent portion, and a space is formed between a center of an air inlet of the stool detection sensor and the first side.

[0015] In an optional embodiment of the present application, the diaper further includes a first side wing made of a flexible material, wherein the first side wing is connected to part or all of the first side edge of the absorption portion and extends in a direction away from the absorption portion.

[0016] In an optional implementation manner of the present application, the center of the air inlet of the stool detection sensor is arranged on the first side; or

[0017] The center of the air inlet of the stool detection sensor is arranged on the outer surface of the absorption part; or the center of the air inlet of the stool detection sensor is arranged on the first side wing.

[0018] In an optional implementation manner of the present application, the first side wing is entirely made of breathable material; or the position of the first side wing for installing or close to the stool detection sensor is made of breathable material.

[0019] In an optional implementation manner of the present application, it further includes a urine detection sensor disposed on the diaper, and the urine detection sensor is electrically connected to the processor.

[0020] In an optional implementation manner of the present application, the urine detection sensor is arranged on the outer surface of the absorption part, and the urine detection sensor includes a humidity sensor.

[0021] In an optional implementation manner of the present application, the stool detection sensor includes a first stool detection sensor and a second stool detection sensor;

[0022] The center of the air inlet of the first stool detection sensor is away from the center line of the length direction of the absorption part in the width direction and close to the first side of the absorption part, and the center of the air inlet of the second stool detection sensor is away from the center line of the length direction of the absorption part in the width direction and close to the second side of the absorption part; or

[0023] The center of the air inlet of the first stool detection sensor is away from the center line of the length direction of the absorption part in the width direction and close to the first side of the absorption part, and the second stool detection sensor is arranged on the center line along the length direction of the absorption part.

[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. All other embodiments obtained by those skilled in the art without creative work based on the embodiments in the present application belong to the scope of protection of the present application.

[0054] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0055] The inventor has found through research that because the urine and feces excretion openings of the human body are both located on the midline of the human body, in the prior art, the urine and feces detection sensors set when using diapers are naturally set on the midline of the diaper (equivalent to the center line L1 of the absorption part 11 described below in this application). In this way, the moisture generated by the excreted urine and the odor gas generated by the feces are closest to the sensor. It can be said that in the prior art, except for the position deviation caused by the installation error, the urine and feces detection sensor is installed on the midline of the diaper. It is the most easily conceivable practice or a conventional technical means. The inventor has confirmed through experimental detection that when there is only feces, the gas sensor for detecting feces (such as VOC sensor, ammonia sensor, hydrogen sulfide sensor, etc.) is easier to detect the feces gas signal if it is set on the midline of the diaper than when it is set far away from the midline. However, when urine is present at the same time or urine comes first and then feces, the gas sensor for detecting feces will find it difficult to detect the feces signal. After analysis, it was found that when urination occurs, especially when urination comes before defecation, urine will be absorbed by the absorbent material in the diaper. The absorbent material that absorbs urine swells and increases in volume, especially at the midline of the human body, forming a structure that is thick in the middle and thin on both sides. After expansion, these absorbent materials are like a gas isolation wall, which hinders the flow and diffusion of volatile gases produced by feces. In this way, volatile gases emitted by feces cannot pass through the wet diapers to enter the gas sensor, and the gas sensor that detects feces is difficult to detect feces in a timely and effective manner, and may even fail to detect feces.

[0056] In order to solve the above technical problems, this embodiment provides a detection system that improves the success rate of stool detection when urine is present in diapers. Figure 4-Figure 16As shown, a 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, wherein the diaper 10 includes an absorbent portion 11 and a fixing portion 12, wherein the fixing portion 12 is used to fix the absorbent portion 11 near the excretion opening of the diaper user, wherein the absorbent portion 11 includes a water-absorbing material, and the absorbent portion 11 has a length direction F1 and a width direction F2, wherein the absorbent portion 11 includes a first side edge 11c and a second side edge 11d that are oppositely arranged in the width direction F2, and the detection device 20 includes a large The stool detection sensor 21 and the processor 23 are electrically connected to the stool detection sensor 21. The stool detection sensor 21 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 away from the center line L1 of the length direction F1 of the absorbent portion 11 in the width direction F2 and is close to the first side edge 11c of the absorbent portion 11, that is, the center of the air inlet of the stool detection sensor 21 is closer to the first side edge 11c than 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 of the distance between the center of the air inlet of the stool detection sensor 21 and the first side edge 11c. The distance between the center of the air inlet of the stool detection sensor 21 and the center line L1 is the distance between the center of the air inlet of the stool detection sensor 21 and the nearest point on the center line L1, and the distance between the center of the air inlet of the stool detection sensor 21 and the first side 11c is the distance to the nearest point on the first side 11c.

[0057] There will be errors in the assembly of the stool detection sensor 21. In the prior art, the center of the air inlet of the stool sensor 21 due to the assembly error will only slightly deviate from the center line L1 and be close to the first side 11c. This is different from the technical solution in which the center of the air inlet of the stool detection sensor 21 is deliberately set to be away from the center line L1 of the length direction F1 of the absorbent part 11 in the width direction F2 and close to the first side 11c of the absorbent part 11 in order to improve the success rate of stool detection when urine exists in the diaper. It should be noted that there are errors in the actual processing of the diaper 10 and the assembly of the stool detection sensor 21. For example, the assembly error under the prior art means will not exceed ±5mm, and within the corresponding error range, it means that the product processing and assembly are qualified; outside the corresponding error range, it means that the product processing and assembly are unqualified.

[0058] The center line L1 is a virtual line on the absorbent portion 11, and its extension direction is consistent with the length direction F1 of the absorbent portion 11. The first side edge 11c and the second side edge 11d are symmetrical along the center line L1, and the center line L1 divides the absorbent portion 11 into two equal parts. The center line L1 can also be regarded as the center line of the diaper 10.

[0059] It can be understood that the first side 11c and the second side 11d can be interchangeable, that is, the first side 11c of the embodiment of the present application, in which the center of the air inlet of the stool detection sensor 21 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 by the second side 11d of the embodiment of the present application, in which the center of the air inlet of the stool detection sensor 21 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, that is, the embodiment of the present application includes the center of the air inlet of the stool detection sensor 21 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, either side (the first side 11c or the second side 11d). In other words, when the diaper 10 is placed on a human body, one side of the absorption portion 11 of the diaper 10 close to the left side of the human body can be defined as a first side 11c, and the other side can be defined as a second side 11d; or one side of the absorption portion 11 of the diaper 10 close to the right side of the human body can be defined as a first side 11c, and the other side can be defined as a second side 11d.

[0060] The length direction of the absorbing part 11 can be referred to as Figure 5 , Figure 7 and Fig.14 The F1 marked therein is the length direction F1 of the lower absorbent portion 11 of the diaper 10 in the unfolded state.

[0061] The width direction of the absorbing part 11 can be referred to as Figure 5 , Figure 7 and Fig.14 The F2 marked in the figure is the width direction F2 of the lower absorbent portion 11 of the diaper in the unfolded state. It should be noted that the diaper 10 can also show the width direction of the absorbent portion 11 in other states, such as when the diaper 10 is in the unfolded state. Figure 4 , Figure 6 , Figure 8-Figure 13 F1 is marked in one of the usage states.

[0062] The center of the air inlet of the stool detection sensor 21 of the embodiment of the present application is located in the width direction F2 of the absorption part 11, away from the center line L1 of the length direction F1 of the absorption part 11 and close to the first side edge 11c of the absorption part 11. In this way, after the diaper absorbs water and expands, since the vicinity of the center line L1 is thicker than the vicinity of the first side edge 11c, the center of the air inlet of the stool detection sensor 21 is set near the first side edge 11c, and more gas volatilized by stool can pass through the absorption part 11 and enter the stool detection sensor than when it is set near the center line L1. If the device 21 is such as a gas sensor, the detection effect will be better, and the volatile gas generated by feces will leak out from the two side edges of the absorption part 11 (the edges where the first side edge 11c and the second side edge 11d are located) and be detected by the feces detection sensor 21, thereby solving the problem in the above prior art that the detection sensors for detecting feces are all set in the middle or near the middle of the outer surface of the diaper, resulting in the situation where feces and urine exist at the same time, especially when urine is discharged first and feces are discharged later, and feces cannot be detected or cannot be detected in time.

[0063] like Figure 5 , Figure 7 and Fig.14 As shown, the absorption part 11 is a sheet-like structure. Figure 4-Figure 15 As shown, the length of the absorbent portion 11 is greater than the width, and the width is greater than the thickness. The absorbent portion 11 has a first end 11a and a second end 11b oppositely disposed in the length direction F1, a first side edge 11c and a second side edge 11d oppositely disposed in the width direction F2, and an inner surface 11e and an outer surface 11f oppositely disposed. When the diaper 10 is placed on a human body, the inner surface 11e of the absorbent portion 11 faces the excretion opening of the human body.

[0064] An embodiment, such as Figure 4-Figure 12As shown, the fixing part 12 is connected to the first end 11a and the second end 11b of the absorption 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 by a human body, the absorption part 11 is wrapped around the lower abdomen, crotch and buttocks of the human body, the front fixing part 121 is set on the abdomen of the human body, and the rear fixing part 122 is set on the waist of the human body. The fixing part 12 also includes a fixing belt 123, which is used to fix the front fixing part 121 and the rear fixing part 122, so that the front fixing part 121 and the rear fixing part 122 together form a ring structure around the waist and abdomen of the diaper user, so as to stably fix the absorption part 11 to the lower abdomen, crotch and buttocks of the diaper user. Thus, the absorption part 11 forms a curved structure, and a storage space is formed inside the absorption part 11. When the diaper user urinates, the urine is absorbed by the absorption part 11, and when the diaper user defecates, the defecation is stored in the storage 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 belt 123 can be a Velcro to improve the convenience of wearing and changing the diaper.

[0065] Another embodiment, such as Fig.13 and Fig.14As shown, the fixing portion 12 is connected to both ends of the first side 11c and both ends of the second side 11d. Specifically, the fixing portion 12 includes a first front fixing portion 121a, a second front fixing portion 121b, a first rear fixing portion 122a, and a second rear fixing portion 122b, wherein the first front fixing portion 121a is connected to one end of the first side 11c, the first rear fixing portion 122a is connected to the other end of the first side 11c, the second front fixing portion 121b is connected to one end of the second side 11d, and the second rear fixing portion 122b is connected to the other end of the second side 11d. Among them, the first front fixing portion 121a and the second front fixing portion 121b are spaced apart in the width direction F2 of the absorption portion 11, the first rear fixing portion 122a and the second rear fixing portion 122b are spaced apart in the width direction F2 of the absorption portion 11, the first front fixing portion 121a and the first rear fixing portion 122a are spaced apart in the length direction F1 of the absorption portion 11, and the second front fixing portion 121b and the second rear fixing portion 122b are spaced apart in the length direction F1 of the absorption portion 11. The fixing part 12 also includes a fixing belt 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, 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 absorption part 11 together form an annular structure around the waist and abdomen of the diaper user, so as to stably fix the absorption part 11 to the lower abdomen, crotch and buttocks of the diaper user.

[0066] Exemplarily, a holding bag 14 is provided at a position on the diaper 10 for setting the stool detection sensor 21, and a holding space 142 for accommodating the stool detection sensor 21 is provided in the holding bag 14. The stool detection sensor 21 can be placed in the holding space 142 to achieve the setting of the stool detection sensor 21 on the diaper 10. It should be noted that the manner in which the stool detection sensor 21 is set on the diaper 10 is not limited thereto, and other manners may also be used. In other embodiments, the stool detection sensor 21 may also be fixed by other means such as pasting, magnetic attraction, etc., and the stool detection sensor 21 may also be set on the absorbent portion 11, such as being set on the outer surface 11f of the absorbent portion 11 at a position close to the first side edge 11c or the second side edge 11d.

[0067] In one embodiment, the stool detection sensor 21 can be arranged in the storage space 142 of the same storage bag 14 together with other components of the detection device 20, such as the processor 23; in another embodiment, the stool detection sensor 21 can be arranged in different positions from other components of the detection device 20, such as the processor 23, which is further illustrated below in conjunction with other figures. It should be noted that if the entire detection device 20 is arranged in the storage space 142 near the first side edge 11c or the second side edge 11d of the absorption part 11, the larger detection device 20 may affect the user's activities and thus affect the comfort. Therefore, in an optional embodiment, the stool detection sensor 21 can be arranged in the storage space 142 near the first side edge 11c or the second side edge 11d of the absorption part 11, and the other parts of the detection device 20 can be arranged in other positions.

[0068] An embodiment, such as Figure 4 and Figure 5 As shown, the stool detection sensor 21 is disposed on the outer surface 11f of the absorbent portion 11, and a gap is formed between the center of the air inlet of the stool detection sensor 21 and the first side edge 11c, and the center of the air inlet of the stool detection sensor 21 is away from the center line L1 of the length direction F1 of the absorbent portion 11 in the width direction F2 and close to the first side edge 11c of the absorbent portion 11. For example, the receiving bag 14 is disposed on the outer surface 11f of the absorbent portion 11 and is spaced from the position of the first side edge 11c, and the receiving bag 14 is away from the center line L1 of the length direction F1 of the absorbent portion 11 in the width direction F2 and close to the first side edge 11c of the absorbent portion 11, and the stool detection sensor 21 is disposed in the receiving bag 14.

[0069] In another embodiment, not shown in the figure, the center of the air inlet of the stool detection sensor 21 is located on the first side 11c. For example, the accommodation bag 14 is arranged at the position of the first side 11c, and the stool detection sensor 21 is arranged in the accommodation bag 14 at the position of the first side 11c.

[0070] Thus, the outer surface 10 f of the diaper 10 may include the outer surface 11 f of the absorbent portion 11 , the first side edge 11 c , and the second side edge 11 d .

[0071] The absorption part 11 includes a first part 111, a second part 112 and a third part 113 which are connected end to end in sequence; when the diaper 10 is used on a human body, the first part 111 covers the lower abdomen of the human body, the second part 112 covers the crotch of the human body, and the third part 113 covers the buttocks of the human body. The defecation opening of the human body is located in the crotch, so when the human body excretes feces, the feces are located on the inner side of the second part 112 covering the crotch of the human body; in order to improve the detection sensitivity, the feces detection sensor 21 should be close to the position of the feces. In one embodiment, as Figure 4 , Figure 5 , Fig.13 and Fig.14 As shown, the stool detection sensor 21 is disposed in the first part 111, and the distance between the center of the air inlet of the stool detection sensor 21 and the second part 112 is less than the distance between the center of the air inlet of the stool detection sensor 21 and the end of the first part 111 away from the second part 112. In another embodiment, not shown in the figure, the stool detection sensor 21 is disposed in the second part 112. In another embodiment, not shown in the figure, the stool detection sensor 21 is disposed in the third part 113, and the distance between the center of the air inlet of the stool detection sensor 21 and the second part 112 is less than the distance between the center of the air inlet of the stool detection sensor 21 and the end of the third part 113 away from the second part 112.

[0072] The stool detection sensor 21 can be disposed on the outer surface 11f of the absorbent portion 11. The above embodiment of the present application takes the stool detection sensor 21 disposed on the outer surface 11f of the absorbent portion 11 as an example for illustrative description. It is understandable that the location where the stool detection sensor 21 is disposed is not limited to the outer surface 11f of the absorbent portion 11. For example, the stool detection sensor 21 can be disposed on the side wings of the diaper 10. Figure 6-Figure 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 connected to part or all of the first side edge 11c of the absorbent portion 11 and extends in a direction away from the absorbent portion 11, and the second side wing 13d is connected to part or all of the second side edge 11d of the absorbent portion 11 and extends in a direction away from the absorbent portion 11; illustratively, the first side wing 13c and the second side wing 13d are arranged on both sides of the absorbent portion 11. Neither the first side wing 13c nor the second side wing 13d contains water-absorbing material. When the diaper 10 is used by a human body, the first side wing 13c and the second side wing 13d can fit the legs of the human body, and when the amount of urine discharged is large, the first side wing 13c and the second side wing 13d can prevent urine from overflowing. The stool detection sensor 21 can be arranged on the first side wing 13c or the second side wing 13d. In order to facilitate fixing of the stool detection sensor 21, a receiving bag 14 adapted to the volume of the stool detection sensor 21 may 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.

[0073] In order to reduce the influence of the first side wing 13c and the second side wing 13d on the stool detection, the first side wing 13c and the second side wing 13d are made of breathable material, such as non-woven fabric. In one embodiment, the first side wing 13c and the second side wing 13d are made of breathable material as a whole. In another embodiment, the first side wing 13c is used to install or is close to the position of the stool detection sensor 21. It is understandable that when the stool detection sensor 21 is set on the second side wing 13d, the position of the second side wing 13d used to install or is close to the stool detection sensor 21 is made of breathable material.

[0074] An embodiment, such as Figure 6 and Figure 7 As shown in FIG. 1 , the center of the air inlet of the stool detection sensor 21 is arranged on the first side wing 13c, but not on the absorption part 11. In another embodiment, as shown in FIG. Figure 8 As shown in FIG. 1 , the center of the air inlet of the stool detection sensor 21 is arranged on the first side 11c. Fig. 9 As shown, the center of the air inlet of the stool detection sensor 21 is set on the outer surface 11f of the absorbent portion 11 but not on the first side wing 13c. Thus, the outer surface 10f of the diaper 10 may include the outer surface 11f of the absorbent portion 11, the first side edge 11c, the second side edge 11d, and the first side wing 13c, the second side wing 13d.

[0075] When at least a portion of the stool detection sensor 21 is disposed on the first side wing 13c, in order to make the stool detection sensor 21 closer to the stool located inside the second portion 112 of the absorbent portion 11 to improve the sensitivity of stool detection, the stool detection sensor 21 can be disposed at different positions of the first side wing 13c as required. Figure 6-Figure 8 As shown, the first side wing 13c includes a first area 13c1 adjacent to the first part 111 of the absorbent portion 11, a second area 13c2 adjacent to the second part 112 of the absorbent portion 11, and a third area 13c3 adjacent to the third part 113 of the absorbent portion 11. In one embodiment, the stool detection sensor 21 is disposed in the first area 13c1, and the distance between the center of the air inlet of the stool detection sensor 21 and the second part 112 is less than the distance between the center of the air inlet of the stool detection sensor 21 and the end of the first part 111 away from the second part 112. In another embodiment, as Fig.10 In another embodiment, not shown in the figure, the stool detection sensor 21 is disposed in the third area 13c3, and the distance between the center of the air inlet of the stool detection sensor 21 and the second portion 112 is less than the distance between the center of the air inlet of the stool detection sensor 21 and the end of the third portion 113 away from the second portion 112.

[0076] In order to improve the reliability of stool detection, multiple stool detection sensors 21 may be provided. Fig.17 As shown, the stool detection sensor 21 includes a first stool detection sensor 21a and a second stool detection sensor 21b, and the first stool detection sensor 21a and the second stool detection sensor 21b are arranged at different positions of the diaper 10. For example, the first stool detection sensor 21a and the second stool detection sensor 21b are arranged at different positions of the absorption part 11, and for another example, the first stool detection sensor 21a and the second stool detection sensor 21b are respectively arranged on the first side wing 13c and the second side wing 13d.

[0077] 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, so feces detection sensors 21 can be set 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 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 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 Fig.11 As shown, the diaper 10 includes two storage bags, namely a first storage bag 14a and a second storage bag 14b. The first storage bag 14a is provided with a first storage space 142a for accommodating the first stool detection sensor 21a, and the second storage bag 14b is provided with a second storage space 142b for accommodating the second stool detection sensor 21b. The first stool detection sensor 21a is arranged in the first storage space 142a, and the second stool detection sensor 21b is arranged in the second storage space 142b. In one case, the first storage bag 14a is arranged on the first side wing 13c, and the second storage bag 14b is arranged on the second side wing 13d. In another case, the first storage bag 14a is arranged on the first side edge 11c, and the second storage bag 14b is arranged on the second side edge 11d. In another case, the first storage bag 14a and the second storage bag 14b are both arranged on the outer surface 11f of the absorption part 11.

[0078] When there is only feces but no urine in the diaper 10, the absorbent material in the absorption part 11 that has not absorbed urine has less obstruction to the volatile gas generated by the feces, and the middle position of the outer surface of the absorption part 11 of the diaper 10 is closest to the feces. If the feces detection sensor 21 is set in the middle position of the outer surface of the diaper 10, a higher feces detection sensitivity can be obtained. Therefore, in order to take into account both the 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 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 set on the center line L1 of the absorption part 11 along the length direction F1. Specifically, an optional embodiment, such as Fig.12 As shown, the diaper 10 includes two storage bags, namely a first storage bag 14a and a second storage bag 14b. The first storage bag 14a is provided with a first storage space 142a for accommodating the first stool detection sensor 21a, and the second storage bag 14b is provided with a second storage space 142b for accommodating the second stool detection sensor 21b. The first stool detection sensor 21a is arranged in the first storage space 142a, and the second stool detection sensor 21b is arranged in the second storage space 142b. In one case, the first storage bag 14a is arranged on the first side wing 13c, and the second storage bag 14b is arranged at the center line L1 position of the outer surface 11f of the absorption part 11. In another case, the first storage bag 14a is arranged on the first side edge 11c of the absorption part 11, and the second storage bag 14b is arranged at the center line L1 position of the outer surface 11f of the absorption part 11. In another case, the first storage bag 14a and the second storage bag 14b are both disposed on the outer surface 11f of the absorbent portion 11, for example, the first storage bag 14a is disposed near the first side edge 11c, and the second storage 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.

[0079] It should be noted that, when the detection device 20 of the present application includes the first stool detection sensor 21a and the second stool detection sensor 21b, the detection device 20 may be one or two. When there is one detection device 20, the first stool detection sensor 21a and the second stool detection sensor 21b of the detection device 20 are separately provided. When there are two detection devices 20, one detection device 20 includes one stool detection sensor.

[0080] Exemplarily, the stool detection sensor 21 includes a gas sensor, such as a hydrogen sulfide sensor, a VOC sensor, or the like, which is capable of detecting volatile gases generated by stool.

[0081] like Fig.16 and Fig.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 absorbent portion 11, and the urine detection sensor 22 includes a humidity sensor. In one embodiment, the urine detection sensor 22 and the stool detection sensor 21 are disposed together at the same position of the diaper 10, such as being disposed in the same receiving bag 14. In another embodiment, the urine detection sensor 22 and the stool detection sensor 21 are disposed at different positions of the diaper 10, and the urine detection sensor 22 can be disposed at a position of the diaper 10 as required, and the embodiment of the present application does not limit the setting position of the urine detection sensor 22.

[0082] In order to be able to remind the caregiver when urination or defecation is detected, in this embodiment, Fig.16 and Fig.17 As shown, the detection device 20 also includes a communication module 24 electrically connected to the processor 23, and the communication module 24 is used to communicate with an external terminal device 30 (such as a mobile phone, a computer, etc.). When the processor 23 detects feces through the feces detection sensor 21 such as a gas sensor and / or detects urine through the urine detection sensor 22 such as a humidity sensor, a corresponding alarm signal is sent to the external terminal device 30 through the communication module 24, and the external terminal device 30 sends a corresponding reminder to the nursing staff. For example, when the processor 23 detects feces through the feces detection sensor 21, a feces alarm signal is sent to the external terminal device 30 through the communication module 24, and the external terminal device 30 sends a feces reminder to the nursing staff after receiving the feces alarm signal; when the processor 23 detects urine through the urine detection sensor 22, a urine alarm signal is sent to the external terminal device 30 through the communication module 24, and the external terminal device 30 sends a urine reminder to the nursing staff after receiving the urine alarm signal. The external terminal device 30 can issue reminders in the form of vibration, sound, text, etc., and can distinguish defecation and urination through vibrations of different frequencies, different sounds, and different texts. In other embodiments, the communication module 24 can also be replaced with an alarm, and the processor 23 is directly electrically connected to the alarm. When the processor 23 detects defecation and urination, it controls the alarm to issue a corresponding alarm to remind the nursing staff.

[0083] <Experimental Data>

[0084] In order to verify the technical effect of this technical solution, the following experiments were conducted.

[0085] Since feces emit a variety of gases with complex components, including H2S, volatile organic compounds (VOCs), etc., it is difficult to directly obtain feces gas. Therefore, sensors sensitive to these gases can be used for testing, for example, sensors sensitive to H2S, sensors sensitive to VOCs, etc.

[0086] In this experiment, three positions P1-P3 for installing stool detection sensors are set for experimental selection. The first position P1 is located near the first side edge 11c of the diaper. The first position P1 is the position of the first side edge 11c of the diaper. Figure 6 The setting position of the stool detection sensor 21 in the corresponding embodiment is located on the first side wing 13c. When the stool detection sensor is set 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 in the length direction F1 of the absorption part 11, and is located on the first part 111 of the absorption part 11 close to the second part 112. The second position P2 is the setting position of the stool detection sensor 21 in the prior art. When the stool detection sensor is set 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 in the length direction F1 of the absorption part 11, and is located on the first part 111 of the absorption part 11 away from the second part 112. When the stool detection sensor is set 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 a containing bag, and each sensor is set in the corresponding containing bag.

[0087] <Experiment 1>

[0088] A VOC sensor that is sensitive to VOC gas emitted by feces is used as the feces detection sensor 21 for testing. There are many such sensors on the market. At the same time, this type of sensor is also sensitive to alcohol gas. Therefore, alcohol gas can be used to simulate feces gas for testing. When this type of sensor detects alcohol gas, the signal will increase, and the signal range is 0-4095.

[0089] S11; the diaper 10 is set on a 1-meter-high child mannequin, and a stool detection sensor 21 and a urine detection sensor 22 are set at the third position P3, the second position P2, and the first position P1 on the outer surface of the diaper 10, wherein the urine detection sensor 22 is a humidity sensor, and the setting position is as Fig.15 As shown;

[0090] S12: Acquire the initial values ​​of the gas sensors and the initial values ​​of the humidity sensors located at the third position P3, the second position P2, and the first position P1;

[0091] S13: Put a paper towel soaked in an alcohol solution of a certain concentration (about 0.2 mg / L alcohol gas will be emitted at 34 degrees Celsius) into the crotch of the human model in the diaper 10 to simulate the situation of defecation without urination;

[0092] S14: After a preset time of 10 minutes, the detection values ​​of the gas sensors and the humidity sensors at the third position P3, the second position P2 and the first position P1 are obtained;

[0093] S15: 100 ml of 34 degrees Celsius pure water was injected into the diaper 10 through a silicone tube whose outlet was fixed to the crotch of the mannequin with a syringe within 1 minute to simulate the simultaneous presence of urination;

[0094] S16: After a preset time of 20 minutes, the detection values ​​of the gas sensors and the humidity sensors at the third position P3, the second position P2, and the first position P1 are obtained.

[0095] The experimental data obtained in this experiment 1 are as follows:

[0096] Table 1

[0097]

[0098] Each difference in the table is the difference between the test value and the initial value before the paper towel is added with alcohol solution.

[0099] From the data of Experiment 1 above, we can know that:

[0100] (1) When only feces are present: 10 minutes after the alcohol solution is added to the paper towel, the detection values ​​of the sensors located at the second position P2 and the first position P1 of the diaper 10 are significantly increased compared to those before the alcohol solution is added to the paper towel. The increase in the detection value of the sensor located at the second position P2 of the diaper 10 is particularly obvious. This indicates that when only feces are present, the sensors set at the second position P2 and the first position P1 of the diaper 10 can detect feces in the diaper 10 in a timely and effective manner, especially when located at the second position P2, the detection effect is better. However, the detection value of the sensor located at the third position P3 of the diaper 10 does not increase significantly, indicating that when only feces are present, the sensors set at the third position P3 of the diaper 10 cannot detect feces in the diaper 10 in a timely and effective manner.

[0101] (2) The situation where both feces and urine exist at the same time: 20 minutes after water is added to the diaper 10, the detection value of the sensor located at the first position P1 of the diaper 10 is significantly increased compared to that before the alcohol solution is added to the paper towel. This indicates that in the presence of feces and urine, the sensor set 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 located at the third position P3 and the second position P2 of the diaper 10 do not increase significantly. Therefore, in the presence of feces and urine, the sensors set 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.

[0102] <Experiment 2>

[0103] An H2S sensor that is sensitive to H2S gas emitted by feces is 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 feces gas for testing. When this type of sensor detects H2S gas, the signal will increase, and the signal range is 0-4095.

[0104] S21; The diaper 10 is set on a 1-meter-high child mannequin, and a stool detection sensor 21 such as a gas sensor and a urine detection sensor 22 such as a humidity sensor is set in the middle (second position P2) and left (first position P1) of the outer surface of the diaper 10, and the setting position is as follows Fig.15 As shown;

[0105] S22: Acquire the initial value of the gas sensor and the initial value of the humidity sensor located at the second position P2 and the first position P1;

[0106] S23: One end of a PTFE tube with an inner diameter of 4 mm is fixed to the crotch of the human model, and the other end is connected to the output end of the flow control valve, and 50 ppm H2S gas is introduced into the diaper 10 at a flow rate of 0.1 L / min to simulate the situation of defecation without urination;

[0107] S24: After a preset time, such as 10 minutes, the detection values ​​of the gas sensors at the second position P2 and the first position P1 and the detection values ​​of the humidity sensors are obtained;

[0108] S25: 200 ml of 34 degrees Celsius pure water was injected into the diaper 10 through another outlet of the silicone tube fixed to the crotch of the mannequin with a syringe within 1 minute to simulate the situation where defecation and urine exist at the same time;

[0109] S26: After a preset time, such as 10 minutes, the detection values ​​of the gas sensors and the humidity sensors at the second position P2 and the first position P1 are obtained.

[0110] The experimental data obtained in this experiment 2 are as follows in Table 2:

[0111] Table 2

[0112]

[0113] The differences in Table 2 are the differences between the detected values ​​and the initial values ​​before the introduction of H2S gas.

[0114] From the data of Experiment 2 above, we can know that:

[0115] (1) When only feces are present: 10 minutes after H2S gas was introduced into the diaper 10, the detection values ​​of the sensors located at the second position P2 and the first position P1 of the diaper 10 increased significantly compared with those 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 detected by the sensor 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 effectively and timely detect feces in the diaper 10.

[0116] (2) The situation where both feces and urine exist at the same time: 10 minutes after water is added to the diaper 10, the detection values ​​of the sensors located at the second position P2 and the first position P1 of the diaper 10 are improved compared with the initial values ​​before the H2S gas is introduced into the diaper 10, but the detection value of the sensor located at the first position P1 of the diaper 10 is improved more significantly. This indicates that in the situation where both feces and urine exist at the same time, the sensors located at the second position P2 and the first position P1 of the diaper 10 can detect feces in the diaper, while the detection of feces in the diaper 10 is more timely and effective when the sensor is located at the first position P1 of the diaper.

[0117] The above is a detailed introduction to the detection system for improving the success rate of stool detection when urine is present in diapers provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for technical personnel in this field, according to the ideas of the present application, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present application.
