[0002] Urine detection is an important part of disease screening and health monitoring, which can effectively reflect the metabolic status, kidney function level and early signs of various diseases, and is a non-invasive and convenient important screening method.

[0003] However, the existing technology still faces many challenges in practical application. Urine test paper is a commonly used detection consumable, but such consumables have high requirements for the storage environment and are easily contaminated by external moisture, microorganisms and the like, so they need to be sealed and stored in special sealed cans. In addition, electrochemical detection technology is increasingly widely used in urine detection due to its high detection efficiency and convenient operation, but quantitative analysis is a core requirement, and existing detection electrodes are difficult to achieve accurate quantification, resulting in large detection result errors, which cannot meet the requirements of clinical diagnosis and daily detection for quantitative accuracy, limiting the popularization and application of electrochemical detection technology in the field of urine detection. SUMMARY

[0004] To solve the above problems in the existing urine test technology, the present application provides a urine test consumable, which comprises a mandrel, a liquid collecting area, a detection assembly and a shell. The liquid collecting area is arranged on the mandrel, the detection assembly is arranged on the mandrel and at least partially located in the liquid collecting area, and the shell is sleeved on the mandrel. The mandrel moves relative to the shell between an extended state and a retracted state. When the mandrel is in the extended state, the liquid collecting area is at least partially exposed outside the shell. When the mandrel is in the retracted state, at least part of the mandrel cooperates with the shell to form a sealed cavity, and the liquid collecting area and at least part of the detection assembly are accommodated in the sealed cavity.

[0005] In an embodiment, the detection assembly comprises a sensing element, the sensing element is in contact with the liquid collecting area, the sensing element extends along the axial direction of the mandrel, and part of the sensing element penetrates out of the shell to form an electrical connection terminal.

[0006] In an embodiment, the sensing element comprises a graphene conductive layer etched on a flexible substrate covering the surface of the mandrel or directly etched on the surface of the mandrel, and a printed conductive layer on the flexible substrate and the surface of the mandrel.

[0007] In an embodiment, a liquid absorbing member is further included, which is arranged on the liquid collecting area and located outside the sensing element.

[0008] In an embodiment, the liquid collecting region comprises a groove opened on the outer wall of the mandrel, the sensing element is arranged in the groove, and the liquid absorbing member is at least partially embedded in the groove.

[0009] In an embodiment, a sealing member is further arranged between the mandrel and the inner wall of the shell, and the mandrel and the inner wall of the shell are sealed and matched by the sealing member to form the sealed cavity.

[0010] In an embodiment, a sleeve is arranged on the mandrel, the sealing member is embedded in the sleeve, and the sleeve is tightly attached to the inner wall of the shell by the sealing member to form a radial seal.

[0011] In an embodiment of the present application, a urine test module is provided, comprising a driving mechanism and a urine test consumable according to any one of the above embodiments. The driving mechanism drives the mandrel to switch between the extended state and the retracted state.

[0012] In an embodiment of the present application, an intelligent toilet is provided, comprising a toilet body and a urine test module according to an embodiment of the above, the urine test module being arranged on the toilet body; further comprising a control unit configured to control the driving mechanism and provide an electrical signal to the urine test module and process a feedback signal thereof.

[0013] In an embodiment of the present application, a urine test method is provided, using a urine test module according to an embodiment of the above, the method comprising the following steps: Switching the mandrel to the extended state to enable the liquid collecting region to collect urine; Switching the mandrel to the retracted state to seal the liquid collecting region containing urine and part of the detection assembly in the sealed cavity; Applying an electrical signal to the detection assembly according to a predetermined detection program and obtaining a feedback signal thereof; determining the concentration of a target analyte in urine based on a pre-stored signal processing algorithm according to the feedback signal.

[0014] Based on the above, compared with the prior art, the urine test consumable, urine test module and detection method, and intelligent toilet provided by the present application have at least the following technical effects: 1. By designing the urine test consumable as a telescopic structure, the mandrel moves relative to the shell between the extended state and the retracted state, which enables the mandrel to be in the retracted state before detection.

[0016] 3. The electrochemical reaction of urine on the detection element occurs when the mandrel is retracted, and a sealed cavity is formed between the mandrel and the inner wall of the shell through the sealing element, which avoids external interference and provides a stable and reliable environment for detection.

DETAILED DESCRIPTION

[0020] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application; as long as there is no conflict, the technical features designed in the different implementation manners described below can be combined with each other; on the basis of the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0021] In the description of the present application, it should be noted that all the terms (including technical terms and scientific terms) used in the present application have the same meanings as those generally understood by a person of ordinary skill in the art to which the present application belongs, and should not be understood as a limitation on the present application; it should be further understood that the terms used in the present application should be understood as having meanings consistent with the meanings of these terms in the context of the present specification and the related art, and should not be understood in an idealized or overly formal sense, unless explicitly defined otherwise in the present application.

[0022] Embodiment one Please refer to Figures 1-6 The urine test consumable provided by the embodiments of the present application can be used in scenarios such as intelligent toilet bowls and urine detection instruments that need to detect urine, and the core is to design the urine test consumable into a telescopic piston structure to realize stable urine detection.

[0023] Specifically, the urine test consumable at least includes a mandrel 1, a liquid collecting area 2, a detection assembly 3 and an outer shell 4. The mandrel 1 is used as a support main body and is preferably a cylindrical structure; the liquid collecting area 2 and the detection assembly 3 are arranged on the mandrel 1, and the detection assembly 3 is at least partially located in the liquid collecting area 2; the mandrel 1 is sleeved with the outer shell 4, so that the mandrel 1 moves between an extended state and a retracted state relative to the outer shell 4; when the mandrel 1 is in the extended state, the liquid collecting area 2 is at least partially exposed outside the outer shell 4; when the mandrel 1 is in the retracted state, at least part of the mandrel 1 cooperates with the outer shell 4 to form a sealed cavity 9, and the liquid collecting area 2 and at least part of the detection assembly 3 are accommodated in the sealed cavity 9.

[0024] In a specific implementation, the detection component 3 can be a urine test paper. In this embodiment, the detection component 3 preferably comprises a sensing element. The sensing element is in contact with the liquid collection area 2 so that the sensing element can contact the liquid in the liquid collection area 2. The sensing element comprises a graphene conductive layer 31 etched on a flexible substrate 5 covering the surface of the mandrel or directly etched on the surface of the mandrel 1, and a printed conductive layer 32 printed on the flexible substrate 5 and the surface of the mandrel 1. The sensing element has the function of sensing target analytes such as uric acid and Vc in urine and can detect the concentration of the target analytes. The flexible substrate 5 is preferably a polyimide film or a fiber material. The printed conductive layer 32 can be made of silver chloride, mercury, or other materials that can provide a reference potential with high stability, serving as a reference electrode and an external conductive connecting wire. In this embodiment, silver chloride is preferably used as the printed conductive layer 32; the sensing element extends axially along the mandrel 1, with the end portion protruding out of the shell 4 to form an electrical connection terminal, which is part of the printed conductive layer 32. The graphene conductive layer 31 and the printed conductive layer 32 are in contact and connected, facilitating the formation of an electrochemical detection loop. When the electrical connection terminal is powered, urine detection can be performed.

[0025] The core function of the liquid collection area 2 is to be able to receive or temporarily store a urine sample, so the design of the liquid collection area 2 has a high degree of flexibility and can be selected according to specific application scenarios and manufacturing processes; preferably, a groove 11 is formed on the outer wall of the mandrel 1 to form a physical liquid collection area 2. The groove 11 can more effectively collect and contain urine, preventing the liquid from flowing away too quickly under the action of gravity, thereby achieving more accurate urine sample quantification. The shape and volume of the groove 11 can be accurately designed according to the required sample volume, for example, it can be a ring-shaped groove, a V-shaped groove, a rectangular groove, an inverted trapezoidal groove, etc., and the sensing element is arranged in the groove 11. In addition, a certain surface of the mandrel 1 exposed in the extended state can also be used as the liquid collection area 2. The outer surface of the mandrel 1 itself can also be used as the liquid collection area 2 by special treatment or structural modification. In order to make the surface have good liquid affinity and liquid holding capacity, the surface can be subjected to surface hydrophilic treatment, such as coating a hydrophilic polymer coating.

[0026] In order to further improve the detection efficiency and reliability, the urine test consumables also include a liquid suction member 21 arranged on the liquid collecting area 2 and outside the sensing element, which actively and quickly guides the urine to the liquid collecting area 2. The liquid suction member 21 in the embodiment of the application is specifically selected to be a water-absorbing cotton, which has excellent water absorption capacity. The liquid suction member 21 can be arranged on the liquid collecting area 2 in a way of drainage or covering, that is, one end of the liquid suction member 21 is tightly overlapped or slightly pressed on the liquid collecting area 2, and the urine is guided from the distal end to the liquid collecting area by capillary action; or the liquid suction member 21 can be partially or entirely covered on the liquid collecting area 2 to accelerate liquid infiltration and distribution. In the embodiment, the sensing element is arranged in the groove 11, and the liquid suction member 21 is at least partially embedded in the groove 11 and covers the sensing element, which can not only ensure the quantitative collection of the urine volume, but also ensure the sufficient contact with the sensing element.

[0027] In addition, a sleeve ring 7 and a sealing member 8 are arranged between the mandrel 1 and the shell 4, the sleeve ring 7 is sleeved on the mandrel 1 and is fixedly adhered to the mandrel 1 at a specified position by the adhesive 6; in the embodiment, the sealing member 8 is specifically two sealing rings, one of which is arranged in the annular groove at the end of the mandrel 1 and is in interference fit with the shell 4, and the other is embedded in the sleeve ring 7 and tightly adheres to the inner wall of the shell 4, the sleeve ring 7 forms a radial seal with the inside of the shell 4 through the sealing member 8; the mandrel 1 and the inner wall of the shell 4 form a sealed cavity 9 through the cooperation of the sealing member 8, specifically, when the mandrel 1 is in the retracted state, the sealing member 8 is in interference fit with the inner wall of the shell 4, forming one or more radial seals, thereby enclosing the sealed cavity 9 together with the shell 4; in addition, when the mandrel 1 is completely retracted, the end face of the sleeve ring 7 abuts against the corresponding step or end cover inside the shell 4, achieving the axial limiting of the mandrel 1 in the retracted state, preventing it from being excessively retracted, on the other hand, also enhancing the structural stability of the sealed cavity 9 and ensuring the reliability of the seal.

[0028] Further, the end of the mandrel has a connecting portion (not marked in the figure), which is used to be connected with the driving mechanism, so as to drive the mandrel to switch between the extended state and the retracted state relative to the shell in cooperation with the driving mechanism.

[0029] Through the above arrangement, the mandrel 1 can be set to the retracted state before detection, so that the liquid collecting area 2 and the sensing element are sealed in the sealed cavity 9, avoiding the sensing element from being contaminated or damp for long-term exposure to air, and the flexible base material 5 and the liquid suction member 21 fixed on the mandrel 1 are also accommodated in the sealed cavity 9 when the mandrel 1 is retracted, so that they are not easily damaged during storage and transportation.

[0030] The working principle of one embodiment is as follows: when detection is needed, the mandrel 1 is first switched to the extended state to expose the liquid collection area 2 to collect a fixed amount of urine, and the liquid suction member 21 adsorbs the urine on the sensing element; then the mandrel 1 is immediately switched to the retracted state, so that the urine sample carried by the liquid collection area 2 and the detection assembly 3 are sealed in the sealed cavity 9, ensuring that the detection sample is basically consistent and improving the repeatability of the detection; when the mandrel 1 is in the retracted state, the urine sample is enclosed in the sealed cavity 9, effectively preventing evaporation, deterioration of the urine, and invasion of external pollutants; thereafter, the electric connection terminals of the mandrel 1 are energized to apply an electric signal to the sensing element, so that the urine sample and the sensing element perform a chemical reaction to detect the corresponding analysis concentration in the urine, and the chemical reaction is limited in the sealed cavity 9 formed by the mandrel 1, the collar 7, the sealing member 8 and the housing 4, avoiding external interference and providing a stable and reliable environment for detection. The above design integrates the functions of sampling, quantification, sealing and detection into a cylindrical structure, making the entire urine test consumable structure very small and compact, facilitating installation and use.

[0031] Embodiment two The embodiment of the present application also provides a urine test module comprising the urine test consumable of any one of the embodiments of the above-mentioned embodiment one. For details about the structure, function and effect of the urine test consumable, please refer to the description of the embodiment one, which will not be repeated here.

[0032] The urine test module comprises a driving mechanism to drive the mandrel 1 to switch between the extended state and the retracted state. Specifically, the driving mechanism can be a simple and economical manual drive, and the user can directly control the mandrel 1 to push out and pull back through a mechanical linkage mechanism such as a knob or a lever without the need for a circuit. Alternatively, the driving mechanism can be a precise automatic motor cooperating with a linear transmission structure to accurately complete the extension and retraction under the instruction of a control unit. As an example, the linear transmission structure includes but is not limited to a crank slider structure, a gear and rack structure, a screw nut structure, a synchronous pulley structure and other conventional structures capable of realizing reciprocating linear motion. In a specific embodiment, the mandrel 1 has a connecting portion (not shown in the figure) for connecting with the driving mechanism to switch between the extended state and the retracted state.

[0033] In addition, a control and processing unit and a power supply device can also be provided. The control and processing unit is responsible for coordinating motion control under the drive of the motor and providing detection signals to the urine test consumable and processing its feedback data. The integrated power supply device provides stable voltage for the driving mechanism and other mechanisms to adapt to different application requirements, which can serve as an automatic detection unit of high-end intelligent equipment or be popularized in a simple and reliable manual form.

[0034] Further, the printed conductive layer of the shell 4 partially exposed to form an electrical connection terminal is sealed to ensure that the detection assembly 3 can work in a dry, stable and sealed environment, thereby ensuring long-term stability and accuracy of the detection results.

[0035] Embodiment three Based on the above-mentioned embodiment two, the present embodiment further provides an intelligent toilet, which seamlessly integrates urine health monitoring function into the daily bathroom mode of the user, and realizes the daily health screening in an unobvious and convenient manner. The intelligent toilet comprises a toilet body and a control unit. An installation cavity is arranged inside or at the rear side of the toilet body, and is used for accommodating a urine test module. The urine test module is isolated from the inner cavity of the toilet by an automatic opening and closing protective cover, and is opened only during detection, thereby effectively preventing pollution and keeping the module clean. The control unit is configured to control a driving mechanism, and provides an electrical signal to the urine test module and processes the feedback signal of the urine test module, so as to obtain the quantitative concentration results of multiple indexes such as glucose, protein and uric acid in the urine.

[0036] Embodiment four The present embodiment further provides a urine detection method, which adopts the urine test module as described in the above-mentioned embodiment two. The structure, function and role design of the urine test module and the adopted urine test consumables can be referred to the above-mentioned embodiments one and two, and will not be described herein again.

[0037] The urine detection method comprises the following steps: Switching the mandrel 1 to the extended state to expose the liquid collecting area 2 outside the shell 4 and collect urine; Switching the mandrel 1 to the retracted state to seal the liquid collecting area 2 containing urine and the detection assembly 3 in the sealed cavity 9, thereby forming a stable detection environment isolated from the outside world; Applying an electrical signal to the detection assembly 3 according to a predetermined detection program, and obtaining the feedback signal. Based on the pre-stored signal processing algorithm, the feedback signal is analyzed and calculated to determine the concentration of the target analyte in the urine.
