Detailed Implementation

[0024] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0025] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0027] In describing some embodiments, the term "connection" and its derivative expressions may be used. The term "connection" should be interpreted broadly; for example, "connection" can be a mechanical connection or an electrical connection; it can be a fixed connection or a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art will understand the specific meaning of the above terms herein based on the specific circumstances.

[0028] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0029] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0030] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0031] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0032] In this disclosure, terms such as “down,” “below,” “above,” and “up” are used to explain the relationships between components shown in the accompanying drawings. The terms may be relative concepts and described based on the directions shown in the drawings, or based on the sequence of process steps, but are not limited thereto.

[0033] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0034] like Figure 1 and Figure 2As shown, some embodiments of this disclosure provide a bandaging pressure detection device 100, including a pressure sensor 10 and a detector 20, with the pressure sensor 10 connected to the detector 20. The pressure sensor 10 has multiple pressure detection points P arranged in an array. The detector 20 includes a data processing module 21 configured to convert the data collected by the pressure sensor 10 into a heat map.

[0035] It's important to note that heatmaps work by mapping data values ​​to a color space. Generally, the larger the data, the more the corresponding color leans towards warmer tones like red; the smaller the data, the more the color leans towards cooler tones like blue. This color coding method allows staff to accurately understand the distribution of data across different areas and quickly identify hot and cold areas.

[0036] In this scenario, when bandaging an injured person, staff can place the pressure sensor 10 under the bandage. The bandage pressure detection device 100 can collect data from multiple pressure detection points P in real time and convert the data into a heat map. Based on the hot and cold areas of the heat map, staff can accurately understand the appropriateness of the bandage pressure in different areas and its distribution. This allows for adjustments to the pressure applied and the area of ​​application, improving the accuracy of the bandage pressure and leading to better treatment outcomes. Furthermore, the bandage pressure detection device 100 is also suitable for training and testing bandage pressure on the human body. During training, trainees can use the device to monitor the appropriateness of the bandage pressure in different areas of the body during bandaging. This allows for adjustments to the pressure applied and the area of ​​application based on the heat map, improving the accuracy of the bandage pressure, quickly mastering bandaging techniques, and shortening the training period.

[0037] For example, multiple pressure detection points P are arranged in an array, with each row including at least two pressure detection points P arranged along a first direction X, and each column including at least two pressure detection points P arranged along a second direction Y. The first direction X and the second direction Y intersect.

[0038] In some embodiments, such as Figure 1 and Figure 3 As shown, the pressure sensor 10 includes a first substrate 11 and a second substrate 12 stacked together, a plurality of first conductive strips 13, a plurality of second conductive strips 14, and a pressure-sensitive material layer 15. The plurality of first conductive strips 13 are disposed on the side of the first substrate 11 near the second substrate 12 and are spaced apart along a first direction X. The plurality of second conductive strips 14 are disposed on the side of the second substrate 12 near the first substrate 11 and are spaced apart along a second direction Y. The pressure-sensitive material layer 15 is disposed on the surfaces of the first conductive strips 13 and the second conductive strips 14 that are close to each other.

[0039] At this time, the intersection of the first conductive strip 13 and the second conductive strip 14 forms an array of multiple pressure detection points P. When the pressure sensor 10 is subjected to pressure, the pressure-sensitive material layer 15 will deform, causing the contact resistance of the first conductive strip 13 and the second conductive strip 14 at the pressure detection point P to decrease, thereby determining the magnitude of the pressure based on the change in resistance.

[0040] For example, the pressure-sensitive material layer 15 may be made of at least one of nanomaterials, graphene, or two-dimensional transition metal sulfides. For instance, two-dimensional transition metal sulfides may include at least one of tungsten disulfide (WS2) or molybdenum disulfide (MoS2).

[0041] In some examples, such as Figure 3 As shown, the pressure-sensitive material layer 15 includes a first sub-part 151 and a second sub-part 152. The first sub-part 151 is disposed on the surface of the first conductive strip 13 near the second conductive strip 14, and the second sub-part 152 is disposed on the surface of the second conductive strip 14 near the first conductive strip 13.

[0042] In some examples, such as Figure 1 and Figure 3 As shown, the first direction X and the second direction Y are perpendicular. At this time, multiple first conductive strips 13 are arranged at intervals along the first direction X, and multiple second conductive strips 14 are arranged at intervals along the second direction Y, with the first direction X and the second direction Y being perpendicular. This ensures that the distance between two adjacent pressure detection points P in the first direction X is equal to the distance between two adjacent pressure detection points P in the second direction Y, thereby achieving a uniform distribution of pressure detection points P and realizing uniform pressure detection at each point within the bandaging area.

[0043] For example, the distance between two adjacent pressure detection points P in the first direction X is equal to the distance between two adjacent pressure detection points P in the second direction Y, and the distance includes 0.5cm to 1cm. For example, the distance includes any one of 0.5cm, 0.55cm, 0.6cm, 0.65cm, 0.7cm, 0.8cm, 0.9cm and 1cm.

[0044] In some embodiments, the materials of the first substrate 11 and the second substrate 12 include at least one of polyimide (PI), polyester, and polypropylene (PP). The first substrate 11 and the second substrate 12 provide support and protection for the pressure sensor 10. Simultaneously, the first substrate 11 and the second substrate 12 ensure that the pressure sensor 10 has sufficient flexibility and conformability, thereby allowing it to closely adhere to the human body surface during bandaging and accurately measure the pressure distribution at different locations during bandaging.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the detector 20 also includes a display screen 22, which is connected to the data processing module 21. The display screen 22 is configured to display a heat map. When staff are bandaging an injured person, they can visually understand whether the bandaging force in different areas is appropriate based on the heat map on the display screen 22, and adjust the force accordingly to achieve better treatment results.

[0046] In other embodiments, the detector 20 further includes a data display module and a second interface. The data display module is connected to the data processing module 21 and the second interface. The data display module is configured to connect to an external device to display the heat map. Exemplary external devices include mobile phones, computers, and televisions. For example, staff can connect the detector 20 to a computer via the second interface to observe the heat map on the computer.

[0047] In some embodiments, such as Figure 4 As shown, the detector 20 is equipped with multiple first interfaces 23, and the bandaging pressure detection device 100 also includes multiple pressure sensors 10 and multiple wires 30. The multiple pressure sensors 10 are connected to the first interfaces 23 through the multiple wires 30. The display screen 22 or an external device can simultaneously display the thermal maps collected by the multiple pressure sensors 10 in split-screen mode, or it can display the thermal maps collected by the multiple pressure sensors 10 in full-screen mode at different times. In this way, one detector 20 can be used simultaneously by multiple workers when bandaging the injured, reducing the number of detectors 20 used and thus reducing equipment costs.

[0048] For example, such as Figure 4 As shown, the detector 20 is equipped with three first interfaces 23, and the bandaging pressure detection device 100 also includes three pressure sensors 10 and three wires 30. In this way, one detector 20 can be used simultaneously by at least three workers when bandaging the injured, reducing the number of detectors 20 used and thus reducing equipment costs.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the detector 20 also includes a data acquisition module 24, which is connected to the pressure sensor 10 and the data processing module 21. The data acquisition module 24 is configured to amplify and preprocess the data acquired by the pressure sensor 10, thereby improving the processing efficiency of the data processing module 21 on the preprocessed data and thus improving the sensitivity of the detector 20.

[0050] In some embodiments, such as Figure 1 and Figure 2As shown, the detector 20 also includes a data storage module 25, which is connected to the data processing module 21. The data storage module 25 is configured to store heat maps. This ensures a complete record of the bandaging process performed on the injured, facilitating subsequent retrieval and access. Furthermore, the stored heat maps provide valuable data for student self-reflection, targeted teacher guidance, and teaching research.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the detector 20 also includes a power supply module 26, which is connected to the data processing module 21, the data acquisition module 24 and the data storage module 25 respectively. The power supply module 26 is configured to supply power to the data processing module 21, the data acquisition module 24 and the data storage module 25.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the detector 20 also includes a housing 27, within which the data processing module 21, data acquisition module 24, data storage module 25, and power module 26 are housed. The housing 27 serves to protect and support the data processing module 21, data acquisition module 24, data storage module 25, and power module 26.

[0053] In some examples, the material of housing 27 includes engineering plastics. For example, the material of housing 27 includes at least one of polyamide (PA), polycarbonate (PC), and polyester. In this case, because engineering plastics have high wear resistance and corrosion resistance, they can provide high protection and support for the detector 20.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the detector 20 also includes a first button 28. The data processing module 21 is further configured to, when the first button 28 is pressed, convert the reference data collected by the pressure sensor 10 into an actual heat map. The data of each pressure detection point P in the actual heat map is compared with the data of each pressure detection point P in the reference heat map to obtain the difference. Based on the difference, compensation is performed on the data of each pressure detection point P collected by the pressure sensor 10. The reference heat map is a heat map obtained from reference data through multiple experiments.

[0055] In this way, before using the bandage pressure detection device 100 to test the bandage pressure, the staff can first calibrate the bandage pressure detection device 100. That is, by applying the pressure of the reference data to the pressure sensor 10 and pressing the first button 28, the data processing module 21 compares the actual heat map generated by the reference data collected by the pressure sensor 10 with the reference heat map, calculates the difference, and then compensates the data of each pressure detection point P collected by the pressure sensor 10 afterward according to the difference, so as to calibrate the bandage pressure detection device 100 and thus ensure the accuracy and reliability of the test results.

[0056] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
