Description
Technical Field
[0001] This disclosure relates to the field of testing equipment technology, and in particular to a testing strip. Background Technology
[0002] In testing, the presence or absence of deformation at the test site is typically detected using equipment. For example, to determine the regularity of a pregnant woman's contractions, a contraction monitoring device is used. However, existing monitoring devices have several shortcomings. First, these devices are usually complex in structure and cumbersome to operate, requiring specialized nurses or caregivers, which increases the consumption of medical resources. Second, these devices are often only usable within hospitals, limiting the location and time of testing and making it inconvenient. Furthermore, the need to travel to the hospital for testing may increase the psychological stress and financial burden on patients. Finally, this method of testing is difficult to achieve real-time, continuous monitoring, and may miss some important changes.
[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content
[0004] This disclosure provides a detection band to at least solve the aforementioned problems in the prior art.
[0005] To achieve the above objectives, this disclosure provides the following technical solution: a detection strip for detecting whether a test portion of an object is deformed, the detection strip comprising:
[0006] A tape body for connecting to the object under test;
[0007] A mechanoluminescent element is attached to the first surface of the tape body. This mechanoluminescent element emits light under pressure. When the tape body is connected to the object under test, the first surface of the tape body faces the object under test, and the mechanoluminescent element is in contact with the portion to be tested.
[0008] When the part to be tested is in a deformed state, the mechanoluminescent body can sense the pressure change caused by the deformation of the part to be tested and emit light.
[0009] In one possible implementation, the object to be tested is a human body, and the part to be tested is the abdomen;
[0010] The number of mechanical light-emitting elements is three groups, and the strip body is provided with a first region, a second region, and a third region in sequence;
[0011] Each of the first region, the second region, and the third region is provided with a set of mechanical light-emitting elements.
[0012] In one embodiment, the number of mechanical light emitters in each group is multiple, and the multiple mechanical light emitters in each group are spaced apart along the length direction of the strip body.
[0013] In one embodiment, the mechanoluminescent material is a film structure formed by mixing mechanically pressure-emitting particles with a flexible material.
[0014] In one embodiment, the luminous intensity of the mechanoluminescent body is positively correlated with the magnitude of the pressure exerted on the mechanoluminescent body.
[0015] In one embodiment, the colors produced by the mechanoluminescent elements in the first region, the second region, and the third region after being subjected to pressure are different.
[0016] In one embodiment, the length of the strap body is 100-150cm, and the width of the strap body is 5-10cm.
[0017] In one embodiment, the first end of the strap body is detachably connected to the second end of the strap body.
[0018] In one embodiment, the first end of the strap body and the second end of the strap body are connected by Velcro or a snap fastener.
[0019] In one embodiment, the strip body is provided with a mounting hole, and the mechanical light emitter is mounted in the mounting hole.
[0020] In the aforementioned detection strip, the strip body is used to connect with the object to be tested, ensuring that the detection strip is fixed on the object. The mechanoluminescent element is connected to the first side of the strip body and is used to sense the pressure change caused by deformation of the test area. It emits light when sensing pressure changes. By observing the light emission of the mechanoluminescent element, it is possible to intuitively determine whether the test area has deformed, and thus detect whether the pregnant woman is experiencing uterine contractions. In this way, the detection strip can effectively detect whether the test area of the object is deformed. Moreover, the detection strip has the advantages of simple structure, convenient operation, and real-time continuous monitoring.

[0031] The embodiments of the present disclosure described above will be described in detail below with reference to the accompanying drawings.
[0032] In the field of testing, detection equipment is typically used to check whether the test site 30 has become deformed. For example, to determine whether a pregnant woman's uterine contractions are regular, a testing instrument is needed to detect these contractions. However, existing testing equipment is complex, requires professional nurses or caregivers to operate, and must be performed within a hospital, making the testing inconvenient.
[0033] This disclosure aims to solve the technical problem of detecting whether the test portion 30 of an object under test is deformed. For this purpose, please refer to... Figure 1 and Figure 2 , Figure 1 This is a cross-sectional view of the test strip disclosed herein. Figure 2 This is a top view of a detection strip disclosed herein. The disclosure proposes a detection strip 10 for detecting whether a test portion 30 of an object is deformed. The detection strip 10 includes a strip body and a mechanoluminescent element 20. The strip body is used to connect to the object under test, ensuring that the detection strip 10 can be fixed to the object. The mechanoluminescent element 20 is connected to the first surface of the strip body and is used to sense pressure changes caused by deformation of the test portion 30, emitting light when pressure changes are sensed. The luminescence state of the mechanoluminescent element 20 allows for a direct visual determination of whether the test portion 30 has deformed.
[0034] Understandably, when a pregnant woman has contractions, the skin on her abdomen deforms and squeezes the mechanoluminescent body 20 on the strap body, so that the mechanoluminescent body 20 is under pressure and emits light.
[0035] In the aforementioned detection band 10, the band body is used to connect with the object to be tested, ensuring that the detection band 10 is fixed on the object to be tested. The mechanoluminescent body 20 is connected to the first side of the band body and is used to sense the pressure change caused by the deformation of the test part 30. When sensing the pressure change, it emits light. By observing the light emission of the mechanoluminescent body 20, it is possible to intuitively determine whether the test part 30 has deformed, and thereby detect whether the pregnant woman has uterine contractions. In this way, the detection band 10 can effectively detect whether the test part 30 of the object to be tested is deformed. Moreover, the detection band 10 has the advantages of simple structure, convenient operation, and real-time continuous monitoring.
[0036] Please see Figure 1 In some embodiments, the number of mechanical light emitters 20 is three sets, the object to be tested is a human body, the part to be tested 30 is the abdomen, and the strap body is provided with a first region 11, a second region 12, and a third region 13 in sequence; each of the first region 11, the second region 12, and the third region 13 is provided with a set of mechanical light emitters 20.
[0037] Thus, by dividing the strip body into a first region 11, a second region 12, and a third region 13, and setting a set of mechanoluminescent bodies 20 in each region, it is possible to detect deformation of the human abdomen. Each set of mechanoluminescent bodies 20 senses pressure changes in the abdomen and emits light, thereby indicating the deformation of the abdomen. This can effectively solve the problem of detecting deformation of the human abdomen. At the same time, the distribution of the mechanoluminescent bodies 20 in the three regions allows the detection strip 10 to monitor different areas of the abdomen, thereby improving the accuracy and reliability of the detection.
[0038] Specifically, the first area 11 corresponds to the left side of the abdomen, the second area 12 corresponds to the middle of the abdomen, and the third area 13 corresponds to the right side of the abdomen, so as to achieve complete coverage of the pregnant woman's abdomen by the detection band 10.
[0039] Please see Figure 2 In some embodiments, there are multiple mechanical light emitters 20 in each group, and the multiple mechanical light emitters 20 in each group are spaced apart along the length direction of the strip body.
[0040] Thus, by arranging multiple mechanoluminescent elements 20 at intervals along the length of the strip body, it can be ensured that the detection strip 10 can sense pressure changes at different locations, avoiding the occurrence of detection blind spots. This design can more comprehensively reflect the deformation of the part 30 to be tested, providing more accurate detection results.
[0041] The number of mechanoluminescent elements 20 in each group can be adjusted according to actual needs; for example, each group can contain 5, 10, or more mechanoluminescent elements 20. The mechanoluminescent elements 20 can be evenly distributed on the tape body by adhesive, sewing, or other fixing methods. To achieve better detection results, the spacing between the mechanoluminescent elements 20 can also be adjusted according to different application scenarios; for example, one mechanoluminescent element 20 can be placed at intervals of 1 cm, 2 cm, or greater.
[0042] In some embodiments, the mechanoluminescent body 20 is a film structure formed by mixing mechanical pressure luminescent particles with a flexible material.
[0043] The mechanoluminescent element 20 is a film-like structure formed by mixing mechanically pressure-emitting particles with a flexible material. By mixing the mechanically pressure-emitting particles with the flexible material to form a film-like structure, the mechanoluminescent element 20 can emit light when subjected to pressure. This solution solves the problem of bonding the mechanoluminescent element 20 with the flexible material by mixing the mechanically pressure-emitting particles with the flexible material, thus enabling the installation of the mechanoluminescent element 20 on the detection strip 10 to emit light when subjected to pressure, indicating whether the tested part 30 is deformed.
[0044] Furthermore, the film structure of the mechanoluminescent material 20 can be achieved in various ways. For example, the mechanoluminescent particles can be uniformly dispersed in a flexible material matrix to form a uniform film layer. Alternatively, the mechanoluminescent particles can be embedded in the flexible material in a specific arrangement to increase the stability of the film structure and the luminescence effect.
[0045] Furthermore, the mechanical pressure luminescent particles are rigid ZnS(M2+(Mn / Cu)@Al2O3) microparticles (ZMPs), or the mechanical pressure luminescent particles include ZnS(M2+(Mn / Cu)@Al2O3) microparticles and SiO2 nanoparticles.
[0046] Furthermore, the flexible material is PDMS (polydimethylsiloxane).
[0047] Understandably, in known related technologies, rigid ZnS (M2+(Mn / Cu)@Al2O3) microparticles (ZMPs) are dispersed in a flexible polydimethylsiloxane (PDMS) film and printed out to form a flexible mechanoluminescent body 20. To adapt to various flexible and sensitive scenarios, SiO2 nanoparticles are used to adjust the elastic modulus of the PDMS matrix. The doped SiO2 nanoparticles can concentrate stress on the ZMPs, achieving strong luminescence of the mechanoluminescent body 20 under weak pressure stimulation; the greater the pressure, the brighter the mechanoluminescent body becomes.
[0048] ZnS(M2+(Mn / Cu)@Al2O3) microparticles are a rigid phosphorescent material responsible for the luminescence effect. The surface is coated with Al2O3 to improve stability and durability. PDMS (polydimethylsiloxane) matrix is a flexible material used to form the support structure. It possesses good elasticity and flexibility, effectively transferring mechanical stress to the luminescent microparticles. SiO2 nanoparticles: These nanoparticles are incorporated into the PDMS matrix to adjust the matrix's elastic modulus. The SiO2 particles enhance stress concentration, thereby improving the photoluminescence intensity of the material under relatively low strain.
[0049] By adding different M to ZnS 2 The color of light emitted can be adjusted by adding metal ions (such as Mn2+, Cu2+, etc.). For example, doping with Mn2+ typically produces orange or red light, while doping with Cu2+ typically produces green light. Other metal ions can be used to further adjust the emission wavelength, achieving different colors of light. The color of light emitted can also be finely adjusted by changing the doping concentration of different metal ions in ZnS. For example, increasing the concentration of Mn2+ enhances orange or red light emission, while increasing the proportion of Cu2+ enhances green light emission. Furthermore, by simultaneously doping with different types of light-emitting ions (such as mixed doping of Mn2+ and Cu2+), mixed colors of light emission, even white light, can be achieved.
[0050] In some embodiments, the luminous intensity of the mechanoluminescent body 20 is positively correlated with the magnitude of the pressure exerted on the mechanoluminescent body 20.
[0051] Thus, the characteristic that the luminescence of the mechanoluminescent body 20 is positively correlated with the pressure it bears allows users to judge the pressure change of the test site 30 by observing the brightness change of the mechanoluminescent body 20, and to judge the intensity of uterine contractions by the brightness of the mechanoluminescent body 20, thereby realizing the detection of uterine contraction intensity.
[0052] Specifically, the brightness of the mechanical light source 20 increases with the increase of the pressure it is subjected to. This design allows users to intuitively judge the change in pressure by the change in brightness.
[0053] In some embodiments, the colors produced by the mechanoluminescent elements 20 in the first region 11, the second region 12, and the third region 13 after being subjected to pressure are different.
[0054] Thus, the mechanoluminescent elements 20 of the first region 11, the second region 12, and the third region 13 are respectively set in the detection band 10, so that the mechanoluminescent elements 20 of each region display different colors after being subjected to pressure. This technical solution helps users to more easily identify and judge the pressure state of different regions through regional division and color change, so as to detect the intensity of uterine contractions at different locations on the abdomen.
[0055] Furthermore, different colors of light in different areas can be achieved through the material of the mechanical light emitter 20 itself, or by applying a light-transmitting film of different colors onto the mechanical light emitter 20.
[0056] In some embodiments, the length of the strap body is 100cm-150cm and the width of the strap body is 5cm-10cm to accommodate different body shapes.
[0057] Furthermore, the strap itself is made of a material with good elasticity and flexibility, allowing the strap to adapt to users of different body types while ensuring comfort.
[0058] In some embodiments, the first end of the tape body is detachably connected to the second end of the tape body, so that users can quickly remove or install the tape body, increasing the convenience and practicality of the detection tape 10.
[0059] Furthermore, the first end of the strap body is connected to the second end of the strap body via Velcro or buckles.
[0060] Thus, the first and second ends of the strap are connected by Velcro or buckles, making the strap easy to install and remove. Velcro and buckles are common connection methods, characterized by simple operation and reliable connection.
[0061] Specifically, the Velcro connection method involves setting a pair of mating Velcro surfaces at the first and second ends of the strap body. The strap body is connected by attaching the Velcro surfaces at both ends together. The snap-on connection method involves setting a snap at the first end of the strap body and a slot at the second end that mates with the snap. The strap body is connected by the snap engaging with the slot.
[0062] In some embodiments, the strip body is provided with a mounting hole, and the mechanical light emitter 20 is mounted in the mounting hole.
[0063] Thus, by providing mounting holes on the tape body, the mechanical light emitter 20 can be easily mounted on the tape body, and the mechanical light emitter 20 is mounted in the mounting holes, ensuring that the mechanical light emitter 20 can be tightly combined with the tape body. Therefore, when the part to be tested 30 is deformed, the mechanical light emitter 20 can accurately sense the pressure change and emit light. Furthermore, the mounting holes can also store and protect the mechanical light emitter 20.
[0064] Furthermore, the mounting holes can take various forms, such as circular, elliptical, or other shapes, to accommodate mechanoluminescent elements 20 of different sizes and shapes. The size and shape of the mounting holes should match the shape of the mechanoluminescent element 20 to ensure that the mechanoluminescent element 20 can be securely mounted on the tape body. The number and location of the mounting holes can be designed according to specific application requirements; for example, multiple mounting holes can be provided at multiple locations on the tape body to mount multiple mechanoluminescent elements 20. The mechanoluminescent element 20 can be installed in the mounting holes using adhesives, clips, or other fixing methods to ensure that it will not fall off during use.
[0065] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily 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.
