[0088] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0089] The embodiments of the present application provide a blood oxygen probe and a monitor, which will be described separately below.

[0090] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a blood oxygen probe provided by an embodiment of the present application. First, an embodiment of the present application provides a blood oxygen probe, which may include a probe body 100, a transmitter 200, a first light guide member 300, a second light guide member 400, and a receiver 500.

[0091] The transmitter 200 is disposed in the probe body 100 and is used to generate a first optical signal. The input end of the first light guide member 300 penetrates through the probe body 100 and faces the transmitter 200 to transmit the first optical signal to the outside of the probe body 100. The input end of the second light guide member 400 is located outside the probe body 100 and is used to receive a second optical signal, which is formed by the first optical signal at least passing through the part to be measured of the organism. The receiver 500 is disposed in the probe body 100 and faces the output end of the second light guide member 400 to receive the second optical signal transmitted by the second light guide member 400 and obtain a first electrical signal based on the second optical signal.

[0092] Therefore, the blood oxygen probe of the embodiment of the present application can be applied to the nuclear magnetic environment. Specifically, in the nuclear magnetic environment, compared with externally disposing the receiver 500 and the transmitter 200 outside the probe body 100 and transmitting the electrical signal to the inside of the probe body 100 through a cable, in the embodiment of the present application, the outside of the probe body 100 transmits the optical signal through the light guide member, so that the signal transmission of the part of the blood oxygen probe located outside the probe body 100 can well resist the electromagnetic interference of the nuclear magnetic environment, and finally the blood oxygen probe can be applied to the nuclear magnetic environment and ensure the accuracy of the detection result of the blood oxygen probe.

[0093] Please continue to refer to Figure 2 , Figure 2 For Figure 1Another structural schematic diagram of the oxygen saturation probe shown. In some embodiments, the oxygen saturation probe may further include a processing component 600, which is detachably connected to the probe body 100, so that when the processing component 600 is connected to the probe body 100, it can obtain a first electrical signal. The processing component 600 is provided with a signal processing module 61, and the signal processing module 61 is used to obtain the blood oxygen parameter data of the organism based on the first electrical signal. The processing component 600 is also used to output the first electrical signal and / or the blood oxygen parameter data to the monitor.

[0094] Then, since the oxygen saturation probe is split into a detachably connected probe body 100 and a processing component 600, when parts such as the transmitter 200, other parts cooperating with the transmitter 200, the receiver 500 or other parts cooperating with the receiver 500 installed on the probe body 100 side are damaged, only the parts on the new probe body 100 side need to be replaced as a whole, and there is no need to replace the components inside the processing component 600; similarly, when parts such as the signal processing module 61 in the processing component 600 or the parts used to output monitoring-related information to the monitor are damaged, only the new processing component 600 needs to be replaced. It can be seen that the oxygen saturation probe applied to the nuclear magnetic environment in the embodiments of the present application has the advantage of lower replacement cost.

[0095] The above is an overall example description of the oxygen saturation probe in the embodiments of the present application. Next, an example description of the structure of the connection between the probe body 100 and the processing component 600 will be continued.

[0096] The oxygen saturation probe may include a first electrical connector 700, and the first electrical connector 700 is arranged on the probe body 100. The processing component 600 is provided with a second electrical connector 62 that is pluggable and unplugable from the first electrical connector 700, so that the processing component 600 and the probe body 100 are detachably connected.

[0097] Then, it may be that the first electrical connector 700 includes a first male head or a first plug, and the second electrical connector 62 includes a first female head or a first socket, or the first electrical connector 700 includes a second female head or a second socket, and the second electrical connector 62 includes a second male head or a second plug. Of course, in actual use, it may be that the first electrical connector 700 includes a first male head and does not include a second female head, or the first electrical connector 700 does not include a first male head and includes a second female head, or the first electrical connector 700 includes a first male head and includes a second female head. The embodiments of the present application do not make limitations in this regard.

[0098] In some embodiments, the probe body 100 may further be provided with a fastening bolt 11, so that the probe body 100 can be screwed and fixed to the processing component 600 through the fastening bolt 11, thereby realizing the detachable connection between the processing component 600 and the probe body 100.

[0099] For example, fastening bolts 11 can be provided on both sides of the first electrical connector 700. After the first electrical connector 700 is plugged into the second electrical connector 62, the fastening bolts 11 can be screwed to the processing component 600 to further improve the connection reliability between the probe body 100 and the processing component 600.

[0100] Please continue to refer to Figure 3 , Figure 3 is Figure 2 a schematic structural diagram of the processing component of the oxygen saturation probe shown. In some embodiments, the processing component 600 may further be provided with at least one of a power supply module 63 and a wireless communication module 64. The power supply module 63 is used to supply power to the processing component 600, and the power supply module 63 is further used to supply power to the inside of the probe body 100 when the processing component 600 is connected to the probe body 100. The wireless communication module 64 is used to wirelessly output the second optical signal and / or the blood oxygen parameter data to the monitor.

[0101] Exemplarily, the processing component 600 may include a first circuit board 65, and the first circuit board 65 may be electrically connected to the second electrical connector 62, so that the first electrical signal received by the receiver 500 can be transmitted to the first circuit board 65 through the first electrical connector 700 and the second electrical connector 62. At least one of the power supply module 63, the wireless communication module 64, and the signal processing module 61 is disposed on the first circuit board 65. It should be noted here that the first circuit board 65 may include two or more separate sub-boards, or may be a complete circuit board, and the embodiments of the present application do not limit this.

[0102] Exemplarily, when the processing component 600 further includes a power supply module 63, the power supply module 63 may include a battery interface, a power management circuit, etc. The battery interface is used to connect to the battery 69. Thus, the battery 69 can be controlled by the power supply module 63 to supply power to the processing component 600 and the inside of the probe body 100. Furthermore, the oxygen saturation probe can obtain external power without being connected to the mains or the monitor through a cable, that is, the oxygen saturation probe and the monitor can be separated from each other, so that the oxygen saturation probe can be conveniently moved to a suitable position.

[0103] It can be understood that the battery 69 can be built into the processing component 600 and non-removable, or the battery 69 can be an external battery 69 filled into the battery accommodating cavity of the processing component 600, and the embodiments of the present application do not limit this.

[0104] In some embodiments, the power supply module 63 may further include a charging circuit installed on the first circuit board 65 to supply power to the battery 69, and the embodiments of the present application do not limit this.

[0105] In some embodiments, the wireless communication module 64 may include a WIFI (Wireless Fidelity) module, an NFC (Near Field Communication) module, a Bluetooth (Bluetooth Low Energy, BLE) module, a Wireless Medical Telemetry Service (WMTS) module, and so on.

[0106] Then, compared with the blood oxygen probe being connected to the monitor by a cable to output the first electrical signal and / or blood oxygen parameter data, the embodiments of the present application can reduce or even eliminate the connection cable between the blood oxygen probe and the monitor, that is, the blood oxygen probe and the monitor can be separated from each other, thereby making the use of the blood oxygen probe more convenient.

[0107] Correspondingly, the processing component 600 may further include an antenna 641. The antenna 641 is electrically connected to the first circuit board 65, and thus is indirectly electrically connected to the wireless communication module 64. Then, the wireless communication module 64 can radiate signals to the monitor through the antenna 641 to output the first electrical signal and / or blood oxygen parameter data.

[0108] It can also be understood that the antenna 641 can be electrically connected to the first circuit board 65 through a wire, a spring piece, or by direct soldering. The embodiments of the present application do not limit this.

[0109] In some embodiments, the processing component 600 may further include a driving module 66. The driving module 66 is disposed on the first circuit board 65 to control the operation of the blood oxygen probe. For example, the driving module 66 can be used to control the operation of the transmitter 200 and / or the receiver 500 when the probe body 100 is connected to the processing component 600.

[0110] In some embodiments, the processing component 600 is further provided with a first electromagnetic shielding structure 67. The signal processing module 61 is disposed within the first electromagnetic shielding structure 67, so that the magnetic field in the nuclear magnetic environment on the signal processing module 61 can be reduced through the first electromagnetic shielding structure 67, thereby improving the accuracy of the measurement structure.

[0111] Among them, since blood has an absorption effect on light of a specific wavelength, every time the heart pumps blood, light of certain wavelengths will be absorbed in large amounts. After the receiver 500 receives the second optical signal and forms the first electrical signal. The transmitter 200 and the receiver 500 can be understood as forming a PPG (Photoplethysmography) sensor. Thus, the signal processing module 61 can calculate the blood oxygen parameter data of the organism through the first electrical signal.

[0112] Specifically, the signal processing module 61 may include a blood oxygen parameter circuit, a blood oxygen and heart rate dual-parameter circuit, etc., and the embodiments of the present application do not limit this.

[0113] In some embodiments, at least one of the power supply module 63 and the wireless communication module 64 may also be disposed within the first electromagnetic shielding structure 67. Thus, electromagnetic shielding of multiple modules can be achieved through one magnetic shielding structure, so as to reduce the overall cost and assembly difficulty of the blood oxygen probe.

[0114] For example, it may be that the power supply module 63 and the signal processing module 61 are disposed within the first electromagnetic shielding structure 67, and the wireless communication module 64 is not disposed within the first electromagnetic shielding structure 67. Or it may be that the power supply module 63 is not disposed within the first electromagnetic shielding structure 67, and the wireless communication module 64 and the signal processing module 61 are disposed within the first electromagnetic shielding structure 67. The embodiments of the present application do not limit this.

[0115] Certainly, in some other embodiments, the drive module 66 may also be disposed within the first electromagnetic shielding structure 67.

[0116] It can also be understood that compared with arranging a circuit board within the processing component 600 to carry the drive module 66, the wireless communication module 64, the power supply module 63, etc., and additionally arranging another circuit board within the probe body 100 to carry the signal processing module 61, the embodiments of the present application can reduce the number of circuit boards to reduce the overall cost of the blood oxygen probe. At the same time, when replacing the overall components on the probe body 100 side later, waste of the circuit board carrying the signal processing module 61 can also be reduced. Of course, as described above, the embodiments of the present application can also reduce the use and waste of the electromagnetic shielding structure required for the blood oxygen probe, thereby further reducing the cost when replacing the blood oxygen probe.

[0117] The specific structure of the first electromagnetic shielding structure 67 can be diverse. For example, the first electromagnetic shielding structure 67 may include a shielding cover, and the shielding cover is mounted on the first circuit board 65. At least one of the power supply module 63, the wireless communication module 64, and the drive optical module and the signal processing module 61 are disposed within the shielding cover.

[0118] In some embodiments, the antenna 641 may be disposed outside the first electromagnetic shielding structure 67 to avoid the first electromagnetic shielding structure 67 shielding the communication connection between the antenna 641 and the monitor.

[0119] In some embodiments, the battery 69 may be disposed outside the first electromagnetic shielding structure 67 to reduce the volume of the first electromagnetic shielding structure 67, thereby reducing the cost of the first electromagnetic shielding structure 67 and the entire blood oxygen probe.

[0120] Of course, in some other embodiments, the processing component 600 may further include a box body 68, the first circuit board 65 is disposed inside the box body 68, and the first electromagnetic shielding structure 67 includes a magnetic shielding layer disposed on the inner surface of the box body 68, etc. The embodiments of the present application do not limit this.

[0121] The above are some examples of the structure on one side of the processing component 600 in the embodiments of the present application. Next, examples of the optional structure on one side of the probe body 100 in the embodiments of the present application will be continued.

[0122] Please continue to refer to Figure 4 , Figure 4 For Figure 1 a schematic structural diagram of another fixing bracket of the blood oxygen probe shown. The blood oxygen probe may further include a first wire 800, and the first wire 800 is disposed inside the probe body 100. One end of the first wire 800 is electrically connected to the first electrical connector 700. The other end of the first wire 800 is electrically connected to the transmitter 200, so that when the first electrical connector 700 and the second electrical connector 62 are connected, the processing component 600 can drive the transmitter 200 to generate a first optical signal.

[0123] For example, the transmitter 200 may include a light source for generating a first optical signal. Then, one end of the first wire 800 may be fixedly welded to the first electrical connector 700, and the other end may be fixedly welded to the light source, so that the connection between the transmitter 200 and the first electrical connector 700 is simpler.

[0124] The light source may only include lamp beads. For example, the positive and negative electrodes of the lamp beads are directly welded to the first wire 800.

[0125] The number of lamp beads may be one or more, and the embodiments of the present application do not limit this. For example, the lamp beads may include a first lamp bead for emitting red light and / or a second lamp bead for emitting green light, so that the lamp beads can emit light of different colors or different wavelengths, in order to improve the accuracy of the measurement results.

[0126] The transmitter 200 may further include a first substrate such as a second circuit board, the lamp beads are mounted on the first substrate, and the first wire 800 is then fixedly welded to the first substrate.

[0127] The transmitter 200 may further include an optical device, and the optical device is disposed between the light-emitting side of the lamp beads and the input end of the first light guide member 300 for optically transforming the light output by the lamp beads. For example, the optical device may be an optical film such as a filter, a brightness enhancement film, and a polarizing film, etc. The optical device may further include an optical lens having a light condensing or light homogenizing function, etc. The embodiments of the present application do not limit this.

[0128] In some embodiments, the blood oxygen probe further includes a second wire 900 disposed within the probe body 100. One end of the second wire 900 is electrically connected to the first electrical connector 700, and the other end of the second wire 900 is electrically connected to the receiver 500, so that when the first electrical connector 700 and the second electrical connector 62 are connected, the processing component 600 can drive the receiver 500 to operate and acquire a first electrical signal.

[0129] In some embodiments, the receiver 500 may include a photosensitive element (Photodiode, PD) such that the photosensitive element can receive the second optical signal and form a first electrical signal based on the second optical signal. Then, one end of the second wire 900 may be directly welded and fixed to the pin of the photosensitive element of the receiver 500.

[0130] The receiver 500 may also include a second substrate such as a third circuit board. The photosensitive element is mounted on the second substrate. The second wire 900 is welded and fixed to the second substrate, and the embodiments of the present application do not limit this.

[0131] In some embodiments, the second wire 900 may have a magnetic shielding layer, thereby avoiding interference of the magnetic field in the nuclear magnetic environment on the first electrical signal transmitted by the second wire 900, and ultimately improving the accuracy of the measurement result of the blood oxygen probe.

[0132] In some embodiments, a first optical channel 1001 and a second optical channel 1002 that are isolated from each other are provided within the probe body 100. The input end of the first light guiding component 300 and the transmitter 200 are both at least partially disposed within the first optical channel 1001. The output end of the second light guiding component 400 and the receiver 500 are both at least partially disposed within the first optical channel 1001.

[0133] Thus, the first optical channel 1001 and the second optical channel 1002 can prevent the first optical signal generated by the transmitter 200 from being directly received by the receiver 500, thereby avoiding interference caused by the transmitter 200 to the receiver 500, and improving the accuracy of the measurement structure of the blood oxygen probe.

[0134] In some embodiments, the blood oxygen probe further includes a fixing bracket 1000 disposed within the probe body 100 and forming the first optical channel 1001 and / or the second optical channel 1002. That is to say, either one of the first channel and the second optical channel 1002 may be formed in the fixing bracket 1000, or both the first optical channel 1001 and the second optical channel 1002 may be formed in the fixing bracket 1000, and the embodiments of the present application do not limit this.

[0135] It can also be understood that the number of the fixing brackets 1000 can be one or two. For example, when the number of the fixing brackets 1000 is two, one fixing bracket 1000 can be respectively formed with a first optical channel 1001, and the other fixing bracket 1000 can be formed with a second optical channel.

[0136] Alternatively, it can also be that the first optical channel 1001 and / or the second optical channel 1002 are formed on the inner wall of the probe body 100, and the embodiments of the present application do not limit this. That is to say, it can be that one of the first optical channel 1001 and the second optical channel 1002 is formed on the inner wall of the probe body 100, or it can be that both the first optical channel 1001 and the second optical channel 1002 are formed on the inner wall of the probe body 100, and the embodiments of the present application do not limit this.

[0137] Please continue to refer to Figure 5 , Figure 5 is Figure 1 a schematic diagram of a fixing structure of the transmitter and the receiver of the oximetry probe shown. In some embodiments, a first encapsulation member 1003 is provided in the first optical channel 1001 to encapsulate and fix at least one of the end of the input end of the first light guiding member 300 and the transmitter 200.

[0138] That is to say, the first encapsulation member 1003 can encapsulate and fix one of the end of the input end of the first light guiding member 300 and the transmitter 200, and the first encapsulation member 1003 can also encapsulate and fix both the end of the input end of the first light guiding member 300 and the transmitter 200, and the embodiments of the present application do not limit this.

[0139] Furthermore, on the one hand, the first encapsulation member 1003 can prevent the user from accidentally pulling out the first light guiding member 300 from the probe body 100. On the other hand, the first encapsulation member 1003 can avoid forming a first gap between the transmitter 200 and / or the input end of the first light guiding member 300 and the inner wall of the first optical channel 1001, thereby avoiding light pollution caused by external light sources entering the input end of the first light guiding member 300 from the first gap, or the first optical signal generated by the transmitter 200 leaking out from the first gap and being received by the receiver 500. Ultimately, the embodiments of the present application can improve the accuracy of the test results.

[0140] In some embodiments, the first encapsulation member 1003 can be made of glue. Then, after the first light guiding member 300 and the transmitter 200 are installed in the first optical channel 1001, glue can be applied or injected at the opening of the first optical channel 1001, so that the first encapsulation member 1003 is formed after the glue is cured. Ultimately, not only the installation and fixation of the transmitter 200 and the first light guiding member 300 are completed, but also light pollution at the transmitter 200 and the first light guiding member 300 can be avoided.

[0141] In some embodiments, a second encapsulation member 1004 is provided in the second optical channel 1002 to encapsulate and fix at least one of the end portion of the output end of the second light guiding member 400 and the receiver 500. That is to say, the second encapsulation member 1004 may encapsulate and fix one of the end portion of the output end of the second light guiding member 400 and the receiver 500, and the second encapsulation member 1004 may also encapsulate and fix both the end portion of the output end of the second light guiding member 400 and the receiver 500. The embodiments of the present application do not limit this.

[0142] Furthermore, on the one hand, it can prevent the user from accidentally pulling out the second light guiding member 400 from the probe body 100. On the other hand, it can avoid the formation of a second gap between the receiver 500 and / or the output end of the second light guiding member 400 and the inner wall of the second optical channel 1002, thereby avoiding light pollution caused by the first optical signal or other external light sources entering the second optical channel 1002 from the second gap, and finally enabling the embodiments of the present application to improve the accuracy of the test results.

[0143] In some embodiments, the second encapsulation member 1004 may be made of glue. Then, after the second light guiding member 400 and the receiver 500 are installed in the second optical channel 1002, glue can be applied or injected at the opening of the second optical channel 1002, so as to form the second encapsulation member 1004 after the glue is cured. Finally, not only the installation and fixation of the transmitter 200 and the second light guiding member 400 are completed, but also light pollution at the transmitter 200 and the second light guiding member 400 can be avoided.

[0144] It can also be understood that in the embodiments of the present application, the first optical channel 1001 may be provided with the first encapsulation member 1003 and the second optical channel 1002 may not be provided with the second encapsulation member 1004, or the first optical channel 1001 may not be provided with the first encapsulation member 1003 and the second optical channel 1002 may be provided with the second encapsulation member 1004, or the first optical channel 1001 may be provided with the first encapsulation member 1003 and the second optical channel 1002 may be provided with the second encapsulation member 1004. The embodiments of the present application do not limit this.

[0145] Alternatively, the input end of the first light guiding member 300 is detachably installed in the first optical channel 1001; and / or, the output end of the second light guiding member 400 is detachably installed in the second optical channel 1002. Thus, when the corresponding first light guiding member 300 and / or second light guiding member 400 is damaged, the corresponding first light guiding member 300 and / or second light guiding member 400 can be pulled out and replaced, so as to reduce the replacement cost during the use of the blood oxygen probe.

[0146] In some embodiments, the blood oxygen probe may further include a wire harness sheath 1100. The wire harness sheath 1100 is made of a deformable material. The wire harness sheath 1100 is installed on the probe body 100 and sleeved on the portions of the first light guide member 300 and the second light guide member 400 that are outside the probe body 100. Thus, the wire harness sheath 1100 can provide good protection for the first light guide member 300 and the second light guide member 400.

[0147] For example, the first light guide member 300 and the second light guide member 400 may be light guide beams such as optical fibers, and the wire harness sheath 1100 is made of soft rubber, so as to prevent stress concentration during the bending process of the first light guide member 300 and the second light guide member 400, thereby playing a role in protecting the first light guide member 300 and the second light guide member 400.

[0148] Please continue to refer to Figure 6 , Figure 6 For Figure 2 the structural schematic diagram of the fixing component of the blood oxygen probe shown. In some embodiments, the blood oxygen probe further includes a fixing component 1200. The fixing component 1200 is used to be fixed to the part of the living being to be measured. At least one of the output end of the first light guide member 300 and the input end of the second light guide member 400 is arranged on the fixing component 1200. Thus, through the fixing component 1200, the corresponding first light guide member 300 and / or the second light guide member 400 can be conveniently fixed to the part of the living being to be measured, so that the blood oxygen probe of the embodiment of the present application has the advantage of being easy to use.

[0149] Exemplarily, please continue to refer to Figure 7 , Figure 7 For Figure 6 the usage scenario diagram of the fixing component shown. The fixing component 1200 may be provided with a first through hole 1201. The output end of the first light guide member 300 is detachably installed in the first through hole 1201. Thus, on the one hand, after the fixing component 1200 is fixed to the part of the living being to be measured, the output end of the first light guide member 300 can direct the first optical signal to the part of the living being to be measured. On the other hand, when the first light guide member 300 is damaged, the fixing component 1200 can be unplugged and the first light guide member 300 and the probe body 100 can be replaced, without replacing the fixing component 1200, thereby further reducing the replacement cost of the blood oxygen probe, or different fixing components 1200 can be reasonably replaced according to the measurement requirements of different target living beings to improve the versatility of the blood oxygen probe.

[0150] In some embodiments, the fixing member 1200 is provided with a second through hole 1202, and the input end of the second light guiding member 400 is detachably mounted in the second through hole 1202. Thus, on the one hand, after the fixing member 1200 is fixed to the part to be measured of the organism, the input end of the second light guiding member 400 can receive the second light signal transmitted through the part to be measured of the organism. On the other hand, when the second light guiding member 400 is damaged, the fixing member 1200 can be unplugged and the second light guiding member 400 and the probe main body 100 can be replaced, without replacing the fixing member 1200, thereby further reducing the replacement cost of the blood oxygen probe, or, according to different measurement requirements of the target organism, different fixing members 1200 can be reasonably replaced to improve the versatility of the blood oxygen probe.

[0151] In some embodiments, the output end of the first light guiding member 300 and the input end of the second light guiding member 400 can be arranged facing each other. Thus, after the part to be measured of the organism is placed between the output end of the first light guiding member 300 and the input end of the second light guiding member 400, the first light signal output by the output end of the first light guiding member 300 can directly irradiate the part to be measured of the organism, and then the first light signal forms a second light signal after passing through the part to be measured of the organism and enters the input end of the second light guiding member 400.

[0152] For example, when the fixing member 1200 includes a first through hole 1201 and a second through hole 1202, the first through hole 1201 and the second through hole 1202 are arranged facing each other in a first direction. The fixing member 1200 further includes a third through hole 1203 for inserting the part to be measured of the organism, and the third through hole 1203 is respectively communicated with the first through hole 1201 and the second through hole 1202, and the opening direction of the third through hole 1203 intersects with the first direction.

[0153] It can be understood that the opening direction of the third through hole 1203 can be perpendicular to the first direction or inclined to each other, and the embodiments of the present application do not limit this.

[0154] For example, if the first direction is the vertical direction, then the opening of the third through hole 1203 can be horizontally oriented, inclined downward or inclined upward, and the embodiments of the present application do not limit this. Then, combined with the fixing member 1200 including the first through hole 1201 and / or the second through hole 1202, during use, the fixing member 1200 can rotate in the horizontal plane, so that the opening of the third through hole 1203 faces a more appropriate angle in the horizontal plane, making the blood oxygen probe more convenient to use.

[0155] In some embodiments, the fixing member 1200 can be a wearable member. For example, the fixing member 1200 can be a finger sleeve, a finger clip or a strap, and the embodiments of the present application do not limit this.

[0156] The above are some illustrative examples of a blood oxygen probe in the embodiments of the present application.

[0157] The embodiments of the present application also provide another blood oxygen probe, which may include a probe body 100, a transmitter 200, a first light guide member 300, a second light guide member 400, a receiver 500, a second wire 900, and a first electrical connector 700. The transmitter 200 is disposed in the probe body 100 and is configured to generate a first optical signal. The input end of the first light guide member 300 penetrates the probe body 100 and faces the transmitter 200 to transmit the first optical signal to the outside of the probe body 100. The input end of the second light guide member 400 is located outside the probe body 100 and is configured to receive a second optical signal, which is formed by the first optical signal passing through at least a biological part to be measured. The receiver 500 is disposed in the probe body 100 and faces the output end of the second light guide member 400 to receive the second optical signal transmitted by the second light guide member 400 and obtain a first electrical signal based on the second optical signal. The second wire 900 is disposed in the probe body 100, and one end of the second wire 900 is electrically connected to the receiver 500. The first electrical connector 700 is disposed on the probe body 100, and the first electrical connector 700 is electrically connected to the other end of the second wire 900 to output the first electrical signal.

[0158] Then, in a first aspect, the blood oxygen probe of the embodiments of the present application can be applied to a nuclear magnetic environment. Specifically, in a nuclear magnetic environment, compared with externally disposing the receiver 500 and the transmitter 200 outside the probe body 100 and transmitting electrical signals to the inside of the probe body 100 through cables, in the embodiments of the present application, the outside of the probe body 100 transmits optical signals through the light guide member, so that the signal transmission of the part of the blood oxygen probe located outside the probe body 100 can well resist the electromagnetic interference of the nuclear magnetic environment, and finally the blood oxygen probe can be applied to the nuclear magnetic environment and ensure the accuracy of the detection result of the blood oxygen probe.

[0159] In a second aspect, since the electrical signal of the receiver 500 is directly output through the second wire 900 and the first electrical connector 700, there is no need to provide a signal processing circuit and a circuit board for carrying the signal processing circuit between the receiver 500 and the first electrical connector 700, thereby reducing the replacement cost of the blood oxygen probe.

[0160] In some embodiments, the probe body 100, the transmitter 200, the first light guide member 300, the second light guide member 400, the receiver 500, the second wire 900, and the first electrical connector 700 may refer to the probe body 100, the transmitter 200, the first light guide member 300, the second light guide member 400, the receiver 500, the second wire 900, and the first electrical connector 700 in the above embodiments respectively, and the embodiments of the present application will not elaborate on this.

[0161] In some embodiments, the blood oxygen probe may further include at least one of a first wire 800, a fixing bracket 1000, a first encapsulation member 1003, a second encapsulation member 1004, a wire harness sheath 1100, and a fixing member 1200. The specific structures of the first wire 800, the fixing bracket 1000, the first encapsulation member 1003, the second encapsulation member 1004, the wire harness sheath 1100, and the fixing member 1200 may refer to the first wire 800, the fixing bracket 1000, the first encapsulation member 1003, the second encapsulation member 1004, the wire harness sheath 1100, and the fixing member 1200 above respectively, and the embodiments of the present application will not elaborate on this here.

[0162] It can be understood that the main difference between the blood oxygen probe in the embodiments of the present application and the blood oxygen probe in the above embodiments is that the blood oxygen probe may include the above-mentioned processing component 600 or may not include the above-mentioned processing component 600.

[0163] For example, when the blood oxygen probe does not include the above-mentioned processing component 600, the first electrical connector 700 may be used to connect to a monitor to output a first electrical signal to the monitor. Correspondingly, the monitor may also have a signal processing module 61, and the signal processing module 61 is used to obtain the blood oxygen parameter data of a living being based on the first electrical signal.

[0164] Please continue to refer to Figure 8 , Figure 8 which is a schematic structural diagram of the first monitoring system provided by the embodiments of the present application. The embodiments of the present application also provide a monitoring system, and the monitoring system may include a monitor 1300 and the above-mentioned blood oxygen probe. The blood oxygen probe may be the above-mentioned blood oxygen probe.

[0165] Please continue to refer to Figure 9 , Figure 9Schematic diagram of the structure of the second monitoring system provided by the embodiments of the present application. The embodiments of the present application further provide a monitoring system, which may include a blood oxygen probe and a monitor 1300. The blood oxygen probe includes a probe body 100, a transmitter 200, a first light guiding component 300, a second light guiding component 400, and a receiver 500. The transmitter 200 is disposed in the probe body 100 and is configured to generate a first optical signal. The input end of the first light guiding component 300 penetrates through the probe body 100 and faces the transmitter 200 to transmit the first optical signal to the outside of the probe body 100. The input end of the second light guiding component 400 is located outside the probe body 100 and is configured to receive a second optical signal, which is formed by the first optical signal at least passing through the part of the organism to be measured. The receiver 500 is disposed in the probe body 100 and faces the output end of the second light guiding component 400 to receive the second optical signal transmitted by the second light guiding component 400 and obtain a first electrical signal based on the second optical signal. The monitor 1300 is detachably connected to the blood oxygen probe so that the monitor 1300 can obtain the first electrical signal when connected to the blood oxygen probe. The monitor 1300 is provided with a signal processing module 61, and the signal processing module 61 is configured to obtain the blood oxygen parameter data of the organism based on the first electrical signal.

[0166] Then, in the first aspect, the blood oxygen probe of the embodiments of the present application can be applied to the nuclear magnetic environment. Specifically, in the nuclear magnetic environment, compared with disposing the receiver 500 and the transmitter 200 outside the probe body 100 and transmitting the electrical signal to the inside of the probe body 100 through a cable, in the embodiments of the present application, the outside of the probe body 100 transmits the optical signal through the light guiding component. Thus, the signal transmission of the part of the blood oxygen probe located outside the probe body 100 can well resist the electromagnetic interference of the nuclear magnetic environment, and finally enables the blood oxygen probe to be applied to the nuclear magnetic environment and ensures the accuracy of the detection result of the blood oxygen probe.

[0167] In the second aspect, since the electrical signal of the receiver 500 is directly output through the second wire 900 and the first electrical connector 700, there is no need to provide a signal processing circuit and a circuit board carrying the signal processing circuit between the receiver 500 and the first electrical connector 700, thereby making the replacement cost of the blood oxygen probe lower.

[0168] In some embodiments, the blood oxygen probe may include a first electrical connector 700. The first electrical connector 700 is disposed on the probe body 100, and the monitor 1300 is provided with a third electrical connector 1301 that is plugged and unplugged with the first electrical connector 700 so that the monitor 1300 and the probe body 100 are detachably connected.

[0169] It can be understood that the main difference between the embodiments of the present application and the above embodiments may be that the blood oxygen probe can be detachably connected to the monitor 1300 through the first electrical connector 700 and / or the fastening bolt 11 provided on the probe body 100, so that the monitor 1300 can drive the blood oxygen probe to work and the blood oxygen probe can output a first electrical signal to the monitor 1300, for the signal processing module 61 of the monitor 1300 to obtain blood oxygen parameter data based on the first electrical signal.
