[0042] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] Combination Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides an excretion liquid detection device, including a flexible substrate 10 and a detection area 20. The detection area includes a detection electrode pair 21 arranged on the flexible substrate 10, and the detection electrode pair 21 is used to connect to a detection device; when the detection area 20 contacts liquid, the inter-electrode resistance of the detection electrode pair 21 can change, and the changed inter-electrode resistance can be detected by the detection device, and a prompt signal is issued.

[0045] In the disclosed embodiment, when the detection area 20 is covered with liquid, the conductivity of the liquid reduces the inter-electrode resistance of the detection electrode pair 21. Here, the more liquid there is, the greater the reduction in resistance, thereby achieving rapid and accurate detection of the liquid.

[0046] The excretion liquid detection device provided by the embodiment of the present disclosure uses a flexible material as the substrate of the device, so that the device can be bent to a certain extent, and the device is relatively thin so that it is convenient to place it on different parts of the patient without causing discomfort. At the same time, a detection area 20 composed of a detection electrode pair 21 is arranged on the flexible substrate 10. In this way, when the detection area 20 contacts the liquid, the inter-electrode resistance of the detection electrode pair 21 can change to generate different electrical signals, and the detection device detects the resistance change and issues a prompt message. Therefore, the liquid discharged by the patient can be detected quickly and timely, and corresponding treatment can be carried out in time.

[0047] In the disclosed embodiment, the thickness of the flexible substrate 10 is less than or equal to 1 mm. In this way, it is convenient to bend the device to a certain extent. Optionally, the thickness of the flexible substrate 10 can be 0.3 mm, 0.5 mm, 0.7 mm, 1 mm, which is not limited here. Here, since the detection electrode pair 21 is disposed on the flexible substrate 10, the detection electrode pair 21 has little effect on the thickness of the device. That is, the thickness of the entire device is equivalent to the thickness of the flexible substrate 10.

[0048] In the embodiment of the present disclosure, the detection electrode pair 21 is disposed on the flexible substrate 10. To ensure the comfort of the user, the back and front sides of the flexible substrate 10 are both continuous and flat planes.

[0049] Optionally, the flexible substrate 10 is a flexible printed circuit board (FPC), that is, a printed circuit made of a flexible insulating substrate, which can meet the needs of small-scale and high-density installation.

[0050] In addition, flexible circuit boards have the characteristics of bending and winding, so they can be arranged arbitrarily according to the spatial layout requirements. At the same time, flexible circuit boards also have good connectivity. In this way, they are easy to assemble and use reliably.

[0051] In the embodiment of the present disclosure, the detection electrode pairs 21 arranged on the flexible substrate 10 can form a detection area 20. Here, the detection area 20 of different shapes can be formed by the arrangement of the detection electrode pairs 21 on the flexible substrate 10.

[0052] In the embodiment of the present disclosure, according to the arrangement of the detection electrode pairs 21, the shape of the detection area 20 can be a regular geometric shape, an irregular geometric shape, or a shape composed of multiple geometric shapes.

[0053] Optionally, the regular geometric shape includes but is not limited to a triangle, a square, a circle or a polygon, etc., wherein the polygon is a regular polygon or an irregular polygon with a side length greater than or equal to 5.

[0054] Optionally, in the figure composed of multiple geometric shapes, the multiple geometric shapes form a figure with a certain pattern according to a set layout, wherein the multiple geometric shapes are the same or different.

[0055] In the embodiment of the present disclosure, the detection electrode pair 21 is used to connect to the detection device, and the detection device uses one or a combination of sound, light and identification to indicate the detection result of the detection electrode pair 21. Here, the detection device has a photoelectric alarm component, and the photoelectric alarm component includes a buzzer and / or an indicator light, so that the detection result can be alarmed by the buzzer and / or the indicator light.

[0056] In the disclosed embodiment, the excretion liquid detection device further includes a hydrophilic film 30, which is disposed on the flexible substrate 10 and covers the detection area 20. In this way, when the hydrophilic film 30 contacts the liquid, water molecules in the liquid can enter the detection area 20, causing the inter-electrode resistance of the detection electrode pair 21 in the detection area 20 to change, and the changed resistance can be detected by the detection device, and a prompt signal is issued.

[0057] Optionally, in some embodiments, a hydrophilic film 30 is coated on the detection area 20 to form a sensitive component whose impedance changes logarithmically with relative humidity. Here, the hydrophilic film 30 is a membrane material with a highly hydrophilic characteristic, which can absorb water and conduct it while effectively blocking other unwanted substances from passing through.

[0067] Optionally, combined Figure 6 As shown, the flexible substrate 10 may be a circular structure, that is, the entire device is a circular structure, forming a shape similar to a "button", so that detection can be performed in a smaller area.

[0068] Optionally, combined Figure 7 As shown, the flexible substrate 10 may also be an elliptical structure.

[0069] Combination Figure 4 As shown, in some embodiments, a plurality of fixing holes 12 are provided on the flexible substrate 10 to fix the flexible substrate 10 in a designated area or connect it with an external component.
