Description

Technical Field

[0001] The present application relates to the technical field of human and animal excrement detection, and in particular to an excrement detection system. Background Art

[0002] People with incontinence, such as infants and patients, need to wear diapers. Diapers need to be changed in time after feces are found in them. If they are not changed in time, the feces in the diaper will come into contact with the skin for a long time, which will cause incontinence dermatitis (commonly known as "red buttocks").

[0003] Diaper replacement is performed by different people in different application scenarios. When adults are in the hospital, it is generally done by nursing staff, which is divided into patients in emergency departments such as ICU and patients in nursing homes. For patients in emergency departments, replacement cost is not the main problem, but due to the large number of affairs in emergency places, most of these patients are in a coma or unconscious state. Therefore, when to replace depends entirely on the observation and sense of responsibility of medical staff. Once incontinence dermatitis occurs, it will undoubtedly make things worse for such patients. For such patients, replacement cost is not the main consideration, but the timeliness of replacement is what needs to be considered. For patients in nursing homes, it is difficult to replace diapers in time because one nursing staff has to take care of many patients. Moreover, such patients need to use diapers for a long time, so replacement cost is also a very important consideration. How to grasp the replacement time is also a key focus. There needs to be a balance between timely discovery and timely replacement (or replacement cost).

[0004] There are two types of people who use diapers at home: one is long-term bedridden patients, and the other is children. For the former, a balance needs to be struck between the timeliness of replacement and the cost of replacement. For children, since there are more only children nowadays, young parents generally love their children, so they do not want their children to have red buttocks, and hope to change them in time. They also hope to change diapers immediately when there is defecation. At the same time, many parents need to work during the day, and usually entrust the elderly or nannies to take care of their children during the day. However, the elderly or nannies sometimes do not change their children in time, which can easily lead to family conflicts after red buttocks occur. For this reason, young parents hope to remind the elderly or nannies in time to discover the occurrence of urination and defecation.

[0005] In order to solve the problem of diapers not being replaced in time, there are diaper detection devices that can meet or partially meet the above requirements on the market. In the prior art, the diaper detection device includes a detection unit, which is arranged on the outside of the diaper. When the detection unit detects the presence of excrement in the diaper, it sends an alarm signal to remind parents or caregivers to change the diaper in time.

[0006] The detection unit detects excrement through the sensors set inside it. The detection unit in the prior art is usually equipped with a group of sensors (such as 201910262683.0). When used correctly, the side where the sensor air inlet is located should be facing the diaper so that the sensor can accurately and timely detect excrement. If the position of the detection unit is not set correctly, the side where the sensor air inlet is located is not facing the diaper, resulting in failure to detect excrement normally.

[0007] For nursing staff in hospitals and nursing homes, as well as caregivers who take care of children or people with mobility difficulties at home, such as the elderly and nannies, the process of installing the diaper detection device on diapers brings them certain troubles. There is a situation where the sensor air inlet is installed upside down, which leads to a decrease in its detection accuracy and causes untimely replacement of diapers. Summary of the invention

When one group of sensors meets the preset conditions, it can confirm the presence of excrement, and can remind the user to change the diaper by alarm or other means; therefore, no matter how the detection unit is placed, the air inlet of one group of sensors is facing the main body of the diaper, and the situation that the position of the detection unit is not correctly set and the excrement cannot be detected normally will not occur. The user can place the detection unit arbitrarily when using it, and there is no need to distinguish the two sides of the detection unit, which is more convenient to use.

[0053] Moreover, a group of sensors facing the main body of the diaper can normally detect excrement. When one of the groups of sensors detects excrement, it is determined that there is excrement in the diaper, so there is no need to distinguish between the front and back sides of the first shell, and any side of the two sides facing the detected position can be detected normally, avoiding the failure to detect excrement in time or even the failure to detect excrement due to incorrect setting of the position of the detection unit.

[0077] 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.

[0078] 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.

[0079] See also Figures 1 to 4 An embodiment of the present application discloses an excrement detection system 100, which includes a detachable diaper 10 and an excrement detection device 20a, wherein the excrement detection device 20a can be mounted on the diaper 10, such as the excrement detection device 20a is mounted on the outer surface 111 of the diaper 10. The excrement detection device 20a can also be removed from the diaper 10 to separate the two, which is convenient for replacing the diaper 10, and convenient for charging or replacing the battery in the excrement detection device 20a.

[0080] The excrement detection system 100 is used to detect excrement, that is, the excrement detection device 20a is used to detect excrement, and the excrement may be urine and / or feces.

[0081] It is understandable that the diaper 10 can be worn by a user, such as the diaper 10 can be worn by an infant or a patient.

[0082] For example, Figures 1 to 4 As shown, the diaper 10 includes a main body 11 and a receiving bag 13 disposed on an outer surface 111 of the main body 11. The main body 11 includes an outer surface 111 and an inner surface 113. It can be understood that the inner surface 113 is a side that fits the user when the user wears it, and the outer surface 111 is a side opposite to the inner surface 113. The outer surface 111 of the main body 11 can be understood as the outer surface 111 of the diaper 10, and the inner surface 113 of the main body 11 can be understood as the inner surface 113 of the diaper 10.

[0083] Continue reading Figures 1 to 4The receiving bag 13 and the main body 11 form a receiving space 132 , and the receiving space 132 has at least an inner side 1321 and an outer side 1322 , wherein the inner side 1321 is a side where the main body 11 is located, and the outer side 1322 is a side where the receiving bag 13 is located.

[0084] Specifically, the storage bag 13 includes a portion fixed to the main body 11, and a portion spaced apart from the main body 11 to form a storage space 132. For example, the storage bag 13 includes a bag portion 131 and a fixing portion 133 connected to the bag portion 131, the fixing portion 133 is connected to the main body 11, that is, the fixing portion 133 is fixed to the outer surface 111 of the main body 11, the bag portion 131 is spaced apart from the main body 11, that is, the bag portion 131 is spaced apart from the outer surface 111 of the main body 11 to form a storage space 132 and a storage bag inlet 134 connected to the storage space 132. The excrement detection device 20a can penetrate into the storage space 132 from the storage bag inlet 134. Therefore, the inner side surface 1321 of the storage space 132 is the side where the outer surface 111 of the main body 11 is located, and the outer side surface 1322 of the storage space 132 is the side where the bag portion 131 of the storage bag 13 is located.

[0085] Continue reading Figures 1 to 4 Exemplarily, the main body 11 has a main body inlet 115 , and the direction of the main body inlet 115 is the same as the direction of the receiving bag inlet 135 .

[0086] Combination Figure 5 and Fig. 9 As shown, the excrement detection device 20a includes a detection unit 20, and the detection unit 20 can penetrate into the accommodation space 132 from the accommodation bag entrance 134. Exemplarily, the size of the accommodation space 132 is roughly matched with the volume of the detection unit 20. When the accommodation space 132 accommodates the detection unit 20, the inner wall of the bag portion 131 in the accommodation bag 13 and the outer surface 111 of the main body 11 together play a certain limiting role on the detection unit 20, which can increase the stability of the detection unit 20 when it is installed in the accommodation bag 13 to a certain extent. When the excrement detection device 20a such as the detection unit 20 is placed in the accommodation space 132, any one of the air inlet 211' of the first excrement sensor 22 and the air inlet 212' of the second excrement sensor 24 faces the inner side 1321, and the other air inlet faces the outer side 1322. That is, when the excrement detection device 20a, such as the detection unit 20, is placed in the accommodating space 132, any one of the air inlet 211' of the first excrement sensor 22 and the air inlet 212' of the second excrement sensor 24 faces the side where the main body 11 is located, and the other air inlet faces the side where the bag portion 131 of the accommodating bag 13 is located.

[0087] The containing bag 13 is usually formed by hot pressing of non-woven fabric, and is a flexible structure, and it is not convenient to set a foolproof structure to avoid placing the detection unit 20 in the wrong direction. Therefore, the excrement detection device 20a of the following embodiments of the present application is particularly suitable for use with the diaper 10 provided with the containing bag 13. Of course, the excrement detection device 20a of the following embodiments of the present application can also be used for other types of diapers, and the excrement detection device 20a of the following embodiments of the present application can be fixed to the outer surface of other types of diapers by pasting, clips and other fixing parts.

[0088] Exemplarily, at least a portion of the area of ​​the main body 11 covered by the receiving bag 13 is breathable. When the excrement detection device 20a, such as the detection unit 20, is placed in the receiving space 132, the air inlet 211' of the first excrement sensor 22 or the air inlet 212' of the second excrement sensor 24 faces the breathable area covered by the receiving bag 13. It is understandable that the inner side of the diaper 10 and the receiving space 132 are breathable. When excrement exists in the diaper 10, changes in excrement-related data can be transmitted to the receiving space 132, so that the excrement detection device 20a, such as the detection unit 20, located in the receiving space 132 can detect the excrement in the diaper 10 in a timely and accurate manner.

[0089] In an optional embodiment of the present application, the area of ​​the main body 11 covered by the containing bag 13 is all breathable, ensuring that when the excrement detection device 20a such as the detection unit 20 is placed in the containing space 132, the first excrement sensor 22 and / or the second excrement sensor 24 can detect the excrement in the diaper 10 in a timely and accurate manner through the breathable area of ​​the main body 11.

[0090] In other optional embodiments of the present application, the accommodation space 132 defined by the accommodation bag 13 and the main body 11 is roughly adapted to the size of the detection unit 20, so that the position of the excrement detection device 20a such as the detection unit 20 placed in the accommodation space 132 is roughly certain. Based on this, the area of ​​the main body 11 covered by the accommodation bag 13 has a ventilation area opposite to the air inlet 211' of the first excrement sensor 22 or the air inlet 212' of the second excrement sensor 24. When the detection unit 20 is placed in the accommodating space 132, the air inlet 211' of the first excrement sensor 22 or the air inlet 212' of the second excrement sensor 24 is opposite to the breathable area, thereby ensuring that the first excrement sensor 22 or the second excrement sensor 24 can detect the excrement in the diaper 10 in a timely and accurate manner through the breathable area of ​​the main body 11, and avoiding the air inlet 211' of the first excrement sensor 22 or the air inlet 212' of the second excrement sensor 24 being blocked by other non-breathable areas.

[0091] Exemplarily, the detection unit 20 includes a first shell 21, a first excrement sensor 22 and a second excrement sensor 24. The first shell 21 is used to be arranged in the accommodating space 132, that is, the first shell 21 is used to be placed in the accommodating space 132, and the first excrement sensor 22 and the second excrement sensor 24 are arranged on the first shell 21, such as the first excrement sensor 22 and the second excrement sensor 24 are arranged in the first shell 21.

[0092] Exemplarily, the first housing 21 includes a first side surface 21e and a second side surface 21f opposite to each other, the air inlet 211' of the first excrement sensor 22 is disposed on the first side surface 21e and faces outward, the first excrement sensor 22 is used to detect an excrement detection signal near the first side surface 21e, the air inlet 212' of the second excrement sensor 24 is disposed on the second side surface 21f and faces outward, and the second excrement sensor 24 is used to detect an excrement detection signal near the second side surface 21f. Specifically, the first excrement sensor 22 can detect an excrement detection signal near the first side surface 21e through the air inlet 211' disposed on the first side surface 21e, and the second excrement sensor 24 can detect an excrement detection signal near the second side surface 21f through the air inlet 212' disposed on the second side surface 21f.

[0093] In the embodiment of the present application, the air inlet 211' of the first excrement sensor 22 is referred to as the first air inlet 211', and the air inlet 212' of the second excrement sensor 24 is referred to as the second air inlet 212'. It can be understood that the first excrement sensor 22 is connected to the outside through the first air inlet 211', so that the first excrement sensor 22 can normally detect excrement; and the second excrement sensor 24 is connected to the outside through the second air inlet 212', so that the second excrement sensor 24 can normally detect excrement.

[0094] Exemplarily, when the excrement detection device 20a, such as the detection unit 20, is placed in the accommodating space 132, the air inlet of any one of the first air inlet 211' of the first excrement sensor 22 and the second air inlet 212' of the second excrement sensor 24 faces the inner side 1321, and the other faces the outer side 1322. In one case, the first air inlet 211' faces the inner side 1321, such as the first air inlet 211' faces the outer surface 111 of the main body 11, and the second air inlet 212' faces the outer side 1322, such as the second air inlet 212' faces the inner wall of the bag 131; in this case, the first side 21e can be in contact with the outer surface 111 of the main body 11, and the second side 21f can be in contact with the inner wall of the bag 131. In another case, the first air inlet 211' faces the outer side surface 1322, for example, the first air inlet 211' faces the inner wall of the bag portion 131, and the second air inlet 212' faces the inner side surface 1321, for example, the second air inlet 212' faces the outer surface 111 of the main body 11; in this case, the first side surface 21e can be fitted with the inner wall of the bag portion 131, and the second side surface 21f can be fitted with the outer surface 111 of the main body 11.

[0095] Exemplarily, the orientation of the first air inlet 211' and the orientation of the second air inlet 212' are substantially opposite, and the orientation of the first air inlet 211' and the orientation of the second air inlet 212' are both substantially perpendicular to the first side surface 21e or the second side surface 21f. It should be noted that, in actual applications, there are processing errors between the first air inlet 211' and the second air inlet 212' during the actual production and processing. Within the range of processing error, the orientation of the first air inlet 211' and the orientation of the second air inlet 212' are opposite. Similarly, within the range of processing error, the orientation of the first air inlet 211' and the orientation of the second air inlet 212' are both perpendicular to the first side surface 21e or the second side surface 21f.

[0096] like Fig. 9 As shown, the detection unit 20 also includes a judgment module 23a, which is communicatively connected to the first excrement sensor 22 and the second excrement sensor 24, and the judgment module 23a is used to: obtain an excrement detection signal near the first side 21e and an excrement detection signal near the second side 21f; when the excrement detection signal near the first side 21e or the excrement detection signal near the second side 21f meets a preset condition, confirm that there is excrement in the diaper 10.

[0097] In actual application of the excrement detection system 100 of the embodiment of the present application, the user can first wear the diaper 10 and then put the excrement detection device 20a such as the detection unit 20 into the accommodation space 132. The user can also first put the excrement detection device 20a such as the detection unit 20 into the accommodation space 132 and then wear the diaper 10. Because the first air inlet 211' of the first excrement sensor 22 and the second air inlet 212' of the second excrement sensor 24 of the embodiment of the present application are arranged on two opposite (or understood as back-facing) first side surfaces 21e and second side surfaces 21f, and the first excrement sensor 22 and the second excrement sensor 24 can both detect excrement detection signals near the side surfaces where their respective air inlets are located through their respective air inlets. Therefore, compared with the technical solution in the prior art that only one sensor is provided in the detection unit and the opening thereof is located on one side of the detection unit, the user does not need to consider the front and back sides of the detection unit 20 when placing the excrement detection device 20a such as the detection unit 20 into the accommodation space 132, that is, the problem that the user needs to identify the front and back sides of the detection unit during the placement of the detection unit in the prior art can be solved, and the user can simply and quickly place the detection unit 20 into the accommodation space 132. In addition, the embodiment of the present application can also solve the problem that some users place the detection unit in the prior art incorrectly, or put the detection surface of the detection unit upside down, resulting in inaccurate detection or even failure.

[0098] That is, the detection unit 20 is provided with two groups of sensors (a first excrement sensor 22 and a second excrement sensor 24), and the air inlets (a first air inlet 211' and a second air inlet 212') of the two groups of sensors (the first excrement sensor 22 and the second excrement sensor 24) are opened in opposite directions. When one of the groups of sensors meets the preset conditions, it can be confirmed that there is excrement, and the user can be reminded to change the diaper 10 by an alarm or other means; therefore, no matter how the detection unit 20 is placed, the air inlet of one group of sensors is facing the main body 11 of the diaper 10, and the situation that the position of the detection unit 20 is not correctly set and the excrement cannot be detected normally will not occur. The user can place the detection unit 20 arbitrarily when using it, and there is no need to distinguish the two sides of the detection unit 20, which is more convenient to use.

[0099] Please continue reading Figures 1 to 9, To further facilitate the user to conveniently and quickly place the excrement detection device 20a, such as the detection unit 20, into the accommodation space 132, the overall shape of the first housing 21 in the embodiment of the present application is flat. Specifically, the first housing 21 has a length L2, a width L3, and a thickness L1. The thickness L1 of the first housing 21 is less than the length L2 and the width L3 of the first housing 21, that is, L1 < L2 and L1 < L3, making the first housing 21 flat. Wherein, the thickness L1 of the first housing 21 is the distance between the first side surface 21e and the second side surface 21f.

[0100] Exemplarily, the first housing 21 further includes a first outer side wall 21a and a second outer side wall 21b that are oppositely arranged, and a third outer side wall 21c and a fourth outer side wall 21d that are oppositely arranged. The first outer side wall 21a, the third outer side wall 21c, the second outer side wall 21b, and the fourth outer side wall 21d are connected in sequence and are all connected between the first side surface 21e and the second side surface 21f. Wherein, the length and width of the first housing 21 are the length and width of the surface where the first side surface 21e or the second side surface 21f is located. Specifically, the length L2 of the first housing 21 is the distance between the first outer side wall 21a and the second outer side wall 21b, and the thickness L1 of the first housing 21 is the distance between the third outer side wall 21c and the fourth outer side wall 21d.

[0101] Exemplarily, the shape of the first side surface 21e is substantially the same as the shape of the second side surface 21f. It should be noted that since the detection unit 20 in the embodiment of the present application can detect excrement through the first excrement sensor 22 with an opening on the first side surface 21e and the second excrement sensor 24 with an opening on the second side surface 21f, the user does not need to identify the front and back when placing the detection unit 20 into the accommodation space 132. Therefore, the embodiment of the present application does not need to design a marking structure on both the first side surface 21e and the second side surface 21f, and the shapes of the two are set to be substantially the same. In this way, during the processing and forming process, the same mold can be used. Compared with processing and forming multiple times using different molds, the embodiment of the present application can save processing procedures. Similarly, there are processing errors between the first side surface 21e and the second side surface 21f during the actual processing of the embodiment of the present application. Within the range of processing errors, the shapes of the first side surface 21e and the second side surface 21f are substantially the same.

[0102] Exemplarily, both the first side surface 21e and the second side surface 21f are planes.

[0103] Exemplarily, the first air inlet 211' of the first excrement sensor 22 is located at the center of the first side 21e, and the second air inlet 212' of the second excrement sensor 24 is located at the center of the second side 21f. The line formed by the center of the first side 21e and the center of the second side 21f is perpendicular to the first side 21e and the second side 21f, thereby ensuring that the relative positions of the first air inlet 211' and the second air inlet 212' are completely corresponding, and the opening directions are completely opposite.

[0104] The first housing 21 may adopt one or more shell structures. Exemplarily, the first housing 21 includes a lower housing 211 and an upper housing 212, the edge of the lower housing 211 is connected to the edge of the upper housing 212, and the lower housing 211 and the upper housing 212 are enclosed to form an accommodation space for accommodating the first excrement sensor 22, the second excrement sensor 24 and the first processor 23. It should be noted that the first housing 21 of the embodiment of the present application may also adopt other shell structures.

[0105] Exemplarily, the lower shell 211 and the upper shell 212 are sealed and connected, that is, the connection position between the lower shell 211 and the upper shell 212 is sealed, such as a sealant or a sealing gasket is provided at the connection between the lower shell 211 and the upper shell 212.

[0106] Exemplarily, the connection between the lower shell 211 and the upper shell 212 may be fixed or detachable. The fixed connection includes but is not limited to adhesive fixation and ultrasonic welding fixation. The detachable connection includes but is not limited to snap-on connection and fasteners such as screw connection.

[0107] In the embodiment of the present application, the judgment module 23a can be understood as the first processor 23, or understood as the first processor 23 including the judgment module 23a. It should be noted that the judgment module 23a of the present application is not limited to the detection unit 20. In other optional embodiments, the judgment module 23a can be a part of other devices of the excrement detection device 20a except the detection unit 20, such as the alarm unit of the excrement detection device 20a (the alarm unit is exemplarily described below in conjunction with other drawings).

[0108] Exemplarily, the determination module 23a is further configured to obtain, at preset time intervals, a feces detection signal detected by the first feces sensor 22 near the first side 21e and a feces detection signal detected by the second feces sensor 24 near the second side 21f.

[0109] Exemplarily, the judgment module 23a is further used to: determine that there is excrement in the diaper 10 when the signal value of the excrement detection signal near the first side 21e or the signal value of the excrement detection signal near the second side 21f is greater than a preset signal value; or determine that there is excrement in the diaper 10 when the signal value change rate of the excrement detection signal near the first side 21e or the signal value change rate of the excrement detection signal near the second side 21f is greater than a preset change rate. That is, the preset conditions include but are not limited to the signal value of the excrement detection signal near the first side 21e or the signal value of the excrement detection signal near the second side 21f being greater than the preset signal value, and the signal value change rate of the excrement detection signal near the first side 21e or the signal value change rate of the excrement detection signal near the second side 21f being greater than the preset change rate.

[0110] The first excrement sensor 22 and the second excrement sensor 24 each include a humidity sensor for detecting the first type of excrement and a gas sensor for detecting the second type of excrement. The judgment module 23a is also used to: determine that the diaper 10 has the first type of excrement when the humidity value of one of the humidity sensors of the first excrement sensor 22 and the second excrement sensor 24 is greater than the preset humidity, or the rate of change of the humidity value of one of them is greater than the preset humidity change rate; determine that the diaper 10 has the second type of excrement when the gas concentration of one of the gas sensors of the first excrement sensor 22 and the second excrement sensor 24 is greater than the preset gas concentration, or the rate of change of the gas concentration of one of them is greater than the preset gas concentration change rate.

[0111] Among them, the gas sensor may include a hydrogen sulfide sensor, a VOC sensor, and the like.

[0112] If the first type of excrement exists in the diaper 10, the moisture in the first type of excrement will cause the humidity of the diaper 10 to increase, and will be conducted to the receiving space 132 defined by the receiving bag 13 and the main body 11 through the breathable area of ​​the main body 11, thereby causing the humidity of the receiving space 132 to increase, so the excrement detection signal includes the humidity of the receiving space 132, and when the humidity of the receiving space 132 is greater than the set threshold, it indicates that the first type of excrement exists in the diaper 10. If the second type of excrement exists in the diaper 10, the volatile components (such as thiol, skatole, etc.) in the second type of excrement volatilize and are conducted to the receiving space 132 through the breathable area of ​​the main body 11, causing the concentration of the corresponding volatile components in the receiving space 132 to increase, so the excrement detection signal includes the concentration of the corresponding volatile components, and when the concentration of the corresponding volatile components in the receiving space 132 is greater than the set threshold, it indicates that the second type of excrement exists in the diaper 10. Illustratively, the first type of excrement is urine, and the second type of excrement is feces.

The judgment module 23a is also used to: after confirming that there is excrement in the diaper 10, send an alarm signal to the alarm module 26; the alarm module 26 is used to issue an alarm after receiving the alarm signal. Therefore, in this embodiment, the excrement detection device 20a is provided with sensors on both sides of the first shell 21 of the detection unit 20, and the air inlets of the two sensors are in opposite directions. No matter which side of the first shell 21 is facing the inner side 1321, there is a group of sensors facing the inner side 1321, and the group of sensors facing the inner side 1321 can perform excrement detection normally. When one of the groups of sensors detects excrement, it is determined that there is excrement in the diaper 10, and an alarm is issued to remind the diaper 10 to be replaced. Therefore, there is no need to distinguish between the front and back sides of the first shell 21, and any side of the two sides facing the inner side 1321 can be detected normally, avoiding the failure to detect excrement in time or even the failure to detect excrement due to incorrect setting of the position of the detection unit 20.

[0114] Exemplarily, the judgment module 23a is further used to: send a first alarm signal to the alarm module 26 after confirming the presence of the first type of excrement in the diaper 10; send a second alarm signal to the alarm module 26 after confirming the presence of the second type of excrement in the diaper 10.
