[0048] Embodiment 1
[0049] The first embodiment provides a blood oxygen sensor, for example, a reusable blood oxygen sensor.
[0050] Please refer to Figure 1-3 In one embodiment, the blood oxygen sensor includes a blood oxygen detection module 100 and a wearing structure 200 .
[0051] Please refer to Figure 3 The blood oxygen detection module 100 includes a first photoelectric device 111 for emitting detection light and a second photoelectric device 121 for receiving detection light, and the blood oxygen detection result is obtained by judging the different degrees of light absorption. The blood oxygen detection module 100 may also include other necessary and non-essential features and structures. Since the detection technology is already in the prior art, it will not be repeated here. Of course, in some embodiments, the positions of the first photoelectric device 111 and the second photoelectric device 121 can be exchanged.
[0052] Please refer to Figure 1-3, the blood oxygen detection module 100 is installed on the wearing structure 200. The wearing structure 200 includes a first mounting body 210, a second mounting body 220 and a connecting body 230. The first mounting body 210, the second mounting body 220 and the connecting body 230 can form a wearing space that matches the wearing part of the human body, for example, forming an elastic or openable and lockable annular structure, or a cylindrical structure that can be inserted into a human body part (such as a finger).
[0053] At least one of the first installation body 210 and the second installation body 220 has a hollow structure made of a flexible material, so that the first installation body 210 and / or the second installation body 220 deforms to conform to the human skin when contacting a part of the human body. Figure 3 The hollow structure means that the first mounting body 210 and / or the second mounting body 220 has at least one cavity 211, 221, so that they can be deformed toward the user's skin surface under the action of external force, thereby forming a shape that can fit the user's skin surface.
[0054] The flexible material used for the first mounting body 210 and / or the second mounting body 220 is mainly a material that will not hurt human skin, especially the skin of newborns, for example, it can be at least one of soft silicone or soft TPE.
[0055] The first mounting body 210 and the second mounting body 220 can not only prevent the wearing structure 200 from crushing the skin, especially the skin of newborns, but also improve the fit between the blood oxygen detection module 100 and human skin, thereby improving the detection results.
[0056] The first photoelectric device 111 is mounted on the first mounting body 210 , and the second photoelectric device 121 is mounted on the second mounting body 220 , and can be arranged opposite to the first photoelectric device 111 for blood oxygen detection.
[0057] Please refer to Figure 1-3 The first mounting body 210 has a first window 212 , and the second mounting body 220 has a second window 222 , so that the first optoelectronic device 111 and the second optoelectronic device 121 can be arranged relative to each other through the first window 212 and the second window 222 .
[0058] like Figure 3 As shown, the first window 212 and the second window 222 can be arranged on the side opposite to the cavity parts of the first mounting body 210 and the second mounting body 220, so that the first optoelectronic device 111 and the human body wearing part and the second optoelectronic device 121 and the human body wearing part respectively form an extrusion state with the corresponding cavities.
[0059] Please continue to refer to Figure 1-3In one embodiment, the first mounting body 210, the second mounting body 220 and the connecting body 230 form an elastic or detachable ring structure, and at least the portion of the wearing structure 200 that is in direct contact with the human body wearing part is made of a flexible material. For example, at least the portion of the first mounting body 210, the second mounting body 220 and the connecting body 230 that is in direct contact with the human body wearing part is made of a flexible material, or the first mounting body 210, the second mounting body 220 and the connecting body 230 are all made of a flexible material, thereby improving the skin-friendliness of the wearing structure 200 and avoiding crushing injuries to the user, especially newborns.
[0060] Specifically, see Figure 1 and 2 In one embodiment, the connector 230 includes a first connector 231 and a second connector 232. The first connector 231 and the second connector 232 may be belt-like structures, such as straps.
[0061] The two ends of the first connecting body 231 are respectively connected to the first mounting body 210 and the second mounting body 220. One end of the second connecting body 232 is connected to the first mounting body 210 or the second mounting body 220, and the other end is a free end 232a, and the free end 232a has a structure capable of forming a detachable fit with at least one of the first mounting body 210, the second mounting body 220, the first connecting body 231 and the blood oxygen detection module 100.
[0062] like Figure 1 and 2 As shown, in one embodiment, the detachable matching structure can be that the free end 232a is bonded to the outer side of the blood oxygen detection module 100 through Velcro. The side of the free end 232a used for contacting the blood oxygen detection module 100 is set as a fur surface 301, and the outer side of the blood oxygen detection module 100 is provided with a Velcro hook surface 302 for matching with the fur surface 301 of the free end 232a.
[0063] In a specific implementation, the free end 232a can be bonded to at least one of the first mounting body 210, the second mounting body 220, the first connecting body 231 and the blood oxygen detection module 100 through Velcro to form an openable and lockable annular structure. The Velcro bonding method is simple to operate and reliable to bond.
[0064] Please refer to Figure 3, the blood oxygen detection module 100 includes a first shell 112 and a second shell 122. The first photoelectric device 111 is installed in the first shell 112, and the second photoelectric device 121 is installed in the second shell 122. The first shell 112 is fixed to the first mounting body 210, and the second shell 122 is fixed to the second mounting body 220. Moreover, the first shell 112 and the second shell 122 are separated from the human body wearing part by the first mounting body 210 and the second mounting body 220, and will not directly contact, so that the first shell 112 and the second shell 122 do not need to be too limited in material. The first shell 112 and the second shell 122 can be made of harder materials than the parts of the first mounting body 210 and the second mounting body 220 that are in direct contact with the human body, such as hard rubber, hard TPU, hard TPE, etc., so as to ensure the strength of the blood oxygen detection module 100 and its service life, and at the same time, there is no need to worry about the first shell 112 and the second shell 122 causing pressure injuries to the skin of the human body wearing part. Therefore, the material hardness of the first shell and the second shell is much greater than the hardness of the parts of the first installation body and the second installation body that are in direct contact with the human body.
[0065] Specifically, please refer to Figure 3 The first housing 112 can be mounted on the first mounting body 210 from top to bottom, and the second housing 122 can be mounted on the second mounting body 220 from bottom to top, so as to ensure that the first photoelectric device 111 and the second photoelectric device 121 can complete the blood oxygen detection through the windows on the first mounting body 210 and the second mounting body 220. The free end 232a of the second connector 232 is detachably bonded to the Velcro hook surface 302 on the first housing 112 of the blood oxygen detection module 100.
[0066] Please refer to Figure 1 and 2 In one embodiment, the first mounting body 210, the second mounting body 220 and the first connecting body 231 are made of flexible materials. The first mounting body 210, the second mounting body 220 and the first connecting body 231 can be bent to form a substantially C-shaped structure. The second connecting body 232 is connected to one side of the opening of the C-shaped structure.
[0067] Furthermore, at least one of the first mounting body 210 , the second mounting body 220 , the first connecting body 231 and the blood oxygen detection module 100 has a perforated buckle 114 for fixing the redundant part of the free end 232 a .
[0068] Please continue to refer to Figure 1 and 2In one embodiment, after the free end 232a of the second connector 232 is connected to the blood oxygen detection module 100, its redundant part can be positioned by a perforated buckle 114 provided on the second shell 122 to prevent the redundant part from falling loose and affecting the use of the blood oxygen probe.

[0100] Embodiment 8
[0101] This eighth embodiment provides an eighth blood oxygen sensor.
[0102] The differences between the blood oxygen sensor provided in the eighth embodiment and the first embodiment include:
[0103] Please refer to Fig.13 The blood oxygen probe also includes an elastic locking mechanism 500, the connecting body 230 includes a first connecting body 231, a second connecting body 232 and a third connecting body 233, the two ends of the first connecting body 231 are respectively connected to the first mounting body 210 and the second mounting body 220, one end of the second connecting body 232 is connected to the first mounting body 210, and the other end of the second connecting body 232 is a free end, one end of the third connecting body 233 is connected to the second mounting body 220, and the other end of the third connecting body 233 is a free end.
[0104] The elastic locking mechanism 500 includes a base 501 and a pressing member 502. The base 501 has a through hole for the free ends of the second connector 232 and the third connector 230 to pass through, and the pressing member 502 is movably arranged on the base 501. After the pressing member 502 is subjected to force, the second connector 232 and the third connector 230 can pass through the through hole. After the pressing member 502 releases the pressure, the second connector 232 and the third connector 230 cannot move in the through hole, wherein the displacement direction of the pressing member 502 relative to the base 501 is perpendicular to the axial direction of the through hole.
[0105] Please refer to Fig.14In one of the variant embodiments, the elastic locking mechanism 500 may further include an elastic member 505 for resetting the pressing member 502. The pressing member 502 and the base 501 have holes designed to be misaligned in a normal state. The pressing member 502 is pressed and moves downward, so that the pressing member 502 and the holes of the base 501 are aligned, so that the second connecting body 232 and the third connecting body 230 pass through the perforation. After the pressing member 502 releases the pressure, the pressing member 502 and the base 501 are offset, so that the second connecting body 232 and the third connecting body 230 cannot move in the perforation. The pressing member 502 and the base 501 are movably arranged so that the perforations of the pressing member 502 and the base 501 can be aligned when subjected to external force, and the elastic member 505 applies a force to the pressing member 502 to push the pressing member 502 back to the misaligned state. The tail ends of the second connecting body 232 and the third connecting body 230 can be connected in a fixed or detachable manner to form a clamping portion 503, thereby facilitating pulling the second connecting body 232 and the third connecting body 230.
[0106] Please continue to refer to Fig.13 When wearing the probe, put the newborn's foot through the second connector 232 and the third connector 230, press the pressing piece 502, then pull the second connector 232 and the third connector 230 through the clamping part 503, adjust the position of the elastic locking mechanism 500, make the soft pad 504 on the elastic locking mechanism 500 contact the newborn's foot, then release the pressing piece 502, the position of the elastic locking mechanism 500 can be fixed, so that the probe is fixed to the newborn's foot. The probe is thin and soft as a whole, and will not produce indentations when worn. The soft pad 504 on the elastic locking mechanism 500 avoids the spring buckle from directly contacting the newborn's skin, making it more comfortable to wear. The binding method of the elastic locking mechanism 500 is simple to operate and reliable to fix.
[0107] Embodiment 9
[0108] This ninth embodiment provides a ninth blood oxygen sensor.
[0109] The differences between the blood oxygen sensor provided in the ninth embodiment and the first embodiment include:
[0110] Please refer to Figure 15-17 The first photoelectric device 111 is installed in the first installation body 210. The first installation body 210 has a cavity 211 for the first photoelectric device 111 to move after being pressed, so as to form a hollow structure. The cavity 211 has a protrusion 213 arranged in the direction of the first photoelectric device 111. There is a gap between the protrusion 213 and the first photoelectric device 111, so as to resist the first photoelectric device 111 after the first photoelectric device 111 moves backwards by a set distance.
[0111] And / or, the second optoelectronic device 121 is installed in the second installation body 220, and the second installation body 220 has a cavity 221 for the second optoelectronic device 121 to move after being pressed, so as to form a hollow structure. For example, in some variations, the cavity 221 is arranged behind the first optoelectronic device 111 and can be located in the moving direction of the first optoelectronic device 111 after being pressed.
[0112] The cavity 221 has a protrusion 223 disposed in the direction of the second optoelectronic device 121 , with a gap between the protrusion 223 and the second optoelectronic device 121 for resisting the second optoelectronic device 121 after the second optoelectronic device 121 moves backwards a set distance.
[0113] The cavities 211, 221 can make the first mounting body 210 and the second mounting body 220 deform to fit the human skin, and the protrusions 213, 223 play a supporting role, used to resist the first photoelectric device 111 and the second photoelectric device 121 when the deformation is too large, so as to prevent them from affecting the detection results due to excessive deformation, and also prevent the first photoelectric device 111 and the second photoelectric device 121 from being pressed and depressed, so that the surrounding parts thereof form protrusions and injure the user's skin.
[0114] Please refer to Fig.16 and 17 When the skin of the newborn contacts the probe surface, the hollow structure can be deformed to adapt to the shape of the skin to prevent the skin from being crushed. In one embodiment, there are two cover plates 214 and 224 on the first mounting body 210 and the second mounting body 220. There are protrusions 213 and 223 on the cover plates 214 and 224. The protrusions 213 and 223 are located in the middle of the back of the first photoelectric device 111 and the second photoelectric device 121. When the skin squeezes the first mounting body 210 and the second mounting body 220, the protrusions 213 and 223 can support the middle surface of the first photoelectric device 111 and the second photoelectric device 121 to avoid the probe from being sunken in the middle and the surrounding part of the probe from being raised, which may cause crushing of the newborn. The protrusion may be a cylindrical protrusion, a conical protrusion, a spherical protrusion or a protrusion of other shapes. In addition to being set on the first mounting body 210 and the second mounting body 220, the protrusion may also be set on the photoelectric devices 111, 121 or the blood oxygen detection module 100.
[0115] For further information, please refer to Fig.16 and 17 In one embodiment, in this embodiment, the first photoelectric device 111 and the second photoelectric device 121 are flush with the corresponding first window 212 and the second window 222 respectively, and the distance between the photoelectric devices can be reduced as much as possible to increase the light intensity of the probe.
[0116] Furthermore, in one embodiment, the first mounting body 210 has a supporting portion and a deforming portion, the supporting portion and the deforming portion enclose a cavity to form a hollow structure. The deforming portion also has a mounting cavity, the first window 212 is opened on the cavity wall of the mounting cavity, and the first optoelectronic device 111 is mounted in the mounting cavity;
[0117] And / or, the second mounting body 220 has a supporting portion and a deforming portion, the supporting portion and the deforming portion enclose a cavity to form a hollow structure. The deforming portion also has a mounting cavity, the second window 222 is opened on the cavity wall of the mounting cavity, and the second optoelectronic device 121 is mounted in the mounting cavity.
[0118] like Fig.16 As shown, the cavities 211, 221 may be arranged to semi-surround the installation cavity from the rear side to form a substantially concave-shaped structure.
[0119] For further information, please refer to Fig.17 In one embodiment, taking the second mounting body 220 as an example, the support portion 225 has a circle of vertical support walls 2251, and the deformation portion 226 has a circle of annular connecting walls 2261. The deformation portion 226 is connected to the support wall 2251 of the support portion 225 through the inner edge or outer edge of the connecting wall 2261, thereby forming a structure that is easy to deform.
[0120] In some embodiments, the thickness of at least the connecting wall 2261 of the deformable portion 226 is less than the thickness of the supporting wall 2251 of the supporting portion 225, thereby forming a more deformable structure. When the skin contacts the surface of the second mounting body 220, the periphery of the probe is more easily deformed to prevent the periphery of the probe from crushing the newborn.
[0121] Here, the second installation body 220 is taken as an example to illustrate a structure of the support portion 225 and the deformation portion 226 . The first installation body 220 may also adopt this structure or a similar structure.
[0122] In this embodiment, the first optoelectronic device 111 and the second optoelectronic device 121 are directly mounted in the first housing 112 and the second housing 122. In other embodiments, the first housing 112 and the first mounting body 210 may be integrated, and / or the second housing 122 and the second mounting body 220 may be integrated.

[0127] Please refer to Fig.18 Taking the installation of the second connector 232 on the second mounting body 220 as an example, the anti-drawing wire 601 at least passes through the second connector 232 and the second mounting body 220 to improve the tensile resistance between the second connector 232 and the second mounting body 220, avoiding long-term use of pulling the second connector 232, causing cracks or breaks between the second connector 232 and the second mounting body 220, and also ensuring that the second window on the second mounting body 220 will not be deformed or cracked due to long-term pulling, thereby ensuring the stability of the second photoelectric device and improving the detection stability of the probe.
[0128] In addition, the anti-drawing wire 601 may also extend all the way into the first connecting body 231 or the first mounting body 210 to further improve the tensile resistance of the probe.
[0129] Please continue to refer to Fig.18 In one embodiment, the anti-drawing wire 601 is disposed in a cable 602 for connecting the second optoelectronic device. In addition, the anti-drawing wire 601 can also be separated from the cable 602 and disposed separately in the probe.
[0130] For further information, please refer to Fig.18 In one embodiment, the anti-drawing wire 601 passes through the second mounting body 220 and is fixed on the surface of the second connecting body 232 , and then the anti-drawing wire 601 is covered and fixed on the second connecting body 232 using the fur surface 301 of the Velcro.
[0131] Of course, in other embodiments, other methods may be used to fix the anti-drawing wire 601 .
