Description

Technical Field

[0001] This application relates to the field of body temperature measurement, and more particularly to a body temperature measurement system and body temperature sensor for use in a magnetic resonance imaging environment. Background Technology

[0002] In magnetic resonance imaging (MRI) environments, conventional body temperature probes suffer from overheating issues, leading to inaccurate measurements and potentially producing artifacts that affect image quality. Currently, fiber optic body temperature probes are used in MRI environments to monitor body temperature, unaffected by the MRI environment. Fiber optic body temperature probes typically work in conjunction with a processing unit to achieve body temperature measurement. However, the inconsistent manufacturing processes of fiber optic body temperature probes result in significant differences in measurement results between different probes and the same processing unit. If a client-side fiber optic body temperature probe is damaged, directly replacing it will reduce the system's measurement accuracy. If high accuracy is required and replacement is necessary, recalibration is required afterward.

[0003] Currently, the common practice is to remove the processing unit from the MRI medical device and return it to the manufacturer for one-to-one calibration with the newly replaced fiber optic temperature probe. However, removing and installing the processing unit on the MRI medical device requires professional personnel from the manufacturer, increasing maintenance costs and potentially affecting the device's performance. Furthermore, MRI medical devices (such as MRI monitors) are expensive, and departments generally do not keep spare machines. During the period of replacing the fiber optic temperature probe and returning it to the factory for calibration, users may face a situation where no equipment is available. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide a body temperature measurement system and body temperature sensor that can be used in a magnetic resonance imaging environment, in order to solve the problems of low measurement accuracy and high calibration cost caused by replacing fiber optic body temperature probes.

[0087] This application provides a body temperature measurement system and body temperature sensor with various embodiments. Based on the concept of ensuring measurement accuracy while saving calibration costs after replacing the fiber optic body temperature probe, the system improves calibration efficiency by generating calibration information that is one-to-one matched with the fiber optic body temperature probe before leaving the factory, eliminating the need for return to the factory for calibration. By setting the calibration unit for calibrating the fiber optic body temperature probe at the body temperature sensor end, the calibration information is stored outside the medical device, avoiding the need to disassemble and reassemble the medical device when calibration is required, thus saving labor costs for disassembly and maintenance.

[0088] This application provides a body temperature measurement system 1000a for use in a magnetic resonance imaging environment. Please refer to [link to relevant documentation]. Figures 1 to 4 This includes the 1100a body temperature sensor and the 1200a medical device.

[0089] In some embodiments, the medical device 1200a is used to emit a first optical signal to the body temperature sensor 1100a; the body temperature sensor 1100a is used to receive the first optical signal, generate a second optical signal based on the first optical signal, and send the second optical signal to the medical device 1200a; the body temperature sensor 1100a is also used to store first information corresponding to the body temperature sensor 1100a, the first information being preset information associated with the characteristics of the body temperature sensor 1100a itself; the medical device 1200a is also used to receive the second optical signal and convert the second optical signal into an electrical signal; the medical device 1200a is also used to acquire the first information and obtain a body temperature measurement result based on the first information and the electrical signal.

[0090] Specifically, in some embodiments, the body temperature sensor 1100a includes a fiber optic body temperature probe 1110, a connector 1120a, and a calibration unit (not shown in the figure). The fiber optic body temperature probe 1110 includes an optical fiber 1111 and an active material 1112 disposed at the first end of the optical fiber 1111. The optical fiber 1111 is used to transmit a first optical signal and a second optical signal, and the active material 1112 is used to receive the first optical signal and emit a second optical signal based on the first optical signal. The body temperature sensor 1100a is connected to the medical device 1200a through the connector 1120a, which has a hollow structure, and the second end of the optical fiber 1111 passes through the connector 1120a. The calibration unit is disposed on the connector 1120a and is used to store first information corresponding to the fiber optic body temperature probe 1110, which is used for acquisition by the medical device 1200a.

[0091] In some embodiments, the medical device 1200a includes a processor 1210a and a display 1220. The processor 1210a includes a processing unit, which comprises a light-emitting circuit, a receiving circuit, and a processing circuit. The light-emitting circuit emits a first light signal to the active material 1112 via an optical fiber 1111. The receiving circuit receives a second light signal emitted by the active material 1112 via the optical fiber 1111 and converts the second light signal into an electrical signal. The processing circuit acquires the first information and the electrical signal, and obtains a body temperature measurement result based on the first information and the electrical signal. The display 1220 displays the body temperature measurement result.

[0092] In the process of measuring body temperature using the body temperature measurement system 1000a provided in this application embodiment, a processing unit is disposed at the medical device 1200a. After the body temperature sensor 1100a and the medical device 1200a are connected through the connector 1120a, the light-emitting circuit of the processing unit of the medical device 1200a emits a first light signal to the active material 1112 of the fiber optic body temperature probe 1110. The fiber optic cable 1111 transmits the first light signal to the active material 1112, thereby exciting the active material 1112 to emit a second light signal. The fiber optic cable 1111 then transmits the second light signal to the receiving circuit of the processing unit. After receiving the second light signal, the receiving circuit converts it into an electrical signal. The calibration unit stores the first information corresponding to the fiber optic body temperature probe 1110. After the processing unit of the medical device 1200a obtains the first information and the electrical signal, it obtains the body temperature measurement result based on the first information and the electrical signal. After obtaining the body temperature measurement result, it is displayed through the display 1220 of the medical device 1200a. In this embodiment, the body temperature sensor 1100a and the medical device 1200a transmit a first optical signal, a second optical signal and first information, and the body temperature measurement result is obtained at the medical device 1200a.

[0093] In some embodiments, the electrical signal is the attenuation time of the second optical signal. After the receiving circuit of the processing unit receives the second optical signal emitted by the active material 1112, it calculates the attenuation time of the second optical signal. The processing unit's arithmetic circuit obtains the body temperature measurement result based on the first information and the attenuation time of the second optical signal.

[0094] In some embodiments, the first information is preset information associated with the characteristics of the fiber optic body temperature probe 1110 itself. Due to the poor consistency of the manufacturing process of the fiber optic body temperature probe 1110, the first information corresponding to different fiber optic body temperature probes 1110 is different, and the first information of the fiber optic body temperature probe 1110 is preset, that is, it has been set before leaving the factory.

[0095] In some embodiments, the first information includes calibration information for the fiber optic temperature probe 1110. The fiber optic temperature probe 1110 is calibrated before leaving the factory, and calibration information matching the fiber optic temperature probe 1110 is stored in the temperature sensor 1100a. When the temperature sensor 1100a is connected to the medical device 1200a, the processing circuit in the processing unit of the medical device 1200a automatically reads the calibration information and obtains the temperature measurement result based on the calibration information and the electrical signal.

[0096] In some embodiments, the first information includes the identity information of the fiber optic temperature probe 1110. The body temperature measurement system 1000a also includes a third-party device for storing the calibration information of the fiber optic temperature probe 1110. The fiber optic temperature probe 1110 is calibrated before leaving the factory, and calibration information that matches the fiber optic temperature probe 1110 one-to-one is stored in the third-party device. When the body temperature sensor 1100a and the third-party device are connected to the medical device 1200a, the processing circuit in the processing unit of the medical device 1200a automatically obtains the identity information and calibration information, finds the corresponding matching calibration information based on the identity information of the fiber optic temperature probe 1110 of the body temperature sensor 1100a, and thus obtains the body temperature measurement result based on the calibration information and the electrical signal.

[0097] This application embodiment generates calibration information that is one-to-one matched with the fiber optic body temperature probe 1110 before leaving the factory and stores it in the body temperature sensor 1100a or a third-party device. This allows the medical device 1200a to quickly read the calibration information and obtain the body temperature measurement result after the user replaces the body temperature sensor 1100a. This ensures high-precision measurement while also achieving calibration-free operation, saving the maintenance cost of returning the device to the factory for calibration. Users can replace the body temperature sensor 1100a immediately after it is damaged, which improves the utilization rate of the body temperature measurement system 1000a.

[0098] In some embodiments, the calibration information includes a lookup table relating the body temperature measurement results of the fiber optic body temperature probe 1110 to electrical signals. The fiber optic body temperature probe 1110 is individually calibrated before leaving the factory, and multiple electrical signals are measured at multiple preset temperatures to obtain the lookup table relating the body temperature measurement results of the fiber optic body temperature probe 1110 to electrical signals.

[0099] It should be noted that the lookup table format is not limited. The lookup table between the body temperature measurement result and the electrical signal of the fiber optic body temperature probe 1110 can be obtained by directly mapping the electrical signal to a preset temperature, or by mapping the electrical signal to a temperature calibration difference. The body temperature measurement result obtained based on the calibration information and the electrical signal can be obtained by directly querying the lookup table based on the electrical signal, or it can be obtained by first calculating the baseline body temperature value based on the electrical signal, then querying the lookup table based on the electrical signal to obtain the temperature calibration difference, and finally obtaining the body temperature measurement result based on the baseline body temperature value and the temperature calibration difference.

[0100] In one embodiment, the fiber optic temperature probe 1110 is tested at multiple preset temperatures before leaving the factory. The attenuation time of the second optical signal emitted by the active material 1112 at each preset temperature is calculated to obtain a temperature-time correlation lookup table for the fiber optic temperature probe 1110. When the temperature sensor 1100a is connected to the medical device 1200a for temperature measurement, the processing unit of the medical device 1200a obtains the attenuation time of the second optical signal and can then obtain the corresponding temperature measurement result based on the aforementioned temperature-time correlation lookup table for the fiber optic temperature probe 1110.

[0101] It should be noted that the electrical signal can also be other optical signal parameters of the second optical signal, such as optical signal intensity, optical signal peak value, etc., as long as they can have a corresponding relationship with temperature, and there are no restrictions here.

[0102] It is understandable that calibration information can be not only a lookup table, but also a lookup formula, lookup graph, etc., as long as it can represent the correspondence between body temperature measurement results and electrical signals. There are no restrictions here.

[0103] In some embodiments, the second end of the optical fiber 1111 is fixed to the connector 1120a. It should be noted that the method of fixing the second end of the optical fiber 1111 to the connector 1120a is not limited. In one embodiment, the second end of the optical fiber 1111 passes through the connector 1120a and is then bonded and fixed to the connector 1120a.

[0104] In some embodiments, to improve the transmission efficiency of optical signals, when connector 1120a is connected to medical device 1200a, the second end of optical fiber 1111 is substantially aligned with the light-emitting circuit and the receiving circuit to achieve stable optical path coupling. It should be noted that the substantial alignment of the second end of optical fiber 1111 with the light-emitting circuit and the receiving circuit can be aligned with the center of optical fiber 1111 or there can be slight deviations. It is understood that the relative positional relationship between the light-emitting circuit and the receiving circuit and optical fiber 1111 is not limited to the manner described above, as long as the optical signal can be transmitted normally between the light-emitting circuit and / or the receiving circuit and the optical fiber 1111. For example, the light-emitting circuit and / or the receiving circuit can also be arranged perpendicular to the extension line of optical fiber 1111, and the optical signal can be transmitted between the light-emitting circuit and / or the receiving circuit and the optical fiber 1111 through reflection by a glass plate or the like.

[0105] In some embodiments, in order to improve the transmission efficiency of optical signals, the end face of the second end of the optical fiber 1111 is substantially flush with the end face of the connector 1120a near the medical device 1200a.

[0106] In some embodiments, please refer to Figure 3The fiber optic temperature probe 1110 also includes a protective sleeve 1113 with one open end. The inner diameter of the protective sleeve 1113 is larger than the outer diameter of the optical fiber 1111, and it can be fitted onto the outer periphery of the optical fiber 1111. The open end of the protective sleeve 1113 is connected to the connector 1120a. The end of the protective sleeve 1113 near the active material 1112 is a closed end, which covers the active material 1112 to prevent the entry of liquids such as disinfectant and contamination of the active material 1112. The outer surface of the protective sleeve 1113 can also be designed to be smooth to prevent damage to the patient's temperature measurement site.

[0107] In some embodiments, since the fiber optic temperature probe 1110 comes into direct contact with the patient during temperature measurement, the protective sleeve 1113 is made of medical-grade polymer material and meets biocompatibility requirements. Simultaneously, the protective sleeve 1113 is made of a flexible material, allowing it to be bent while effectively protecting the fiber optic cable 1111. The material of the protective sleeve 1113 also supports cleaning, disinfection, and sterilization, ensuring patient health while protecting the active material 1112 from contamination.

[0108] In some embodiments, after the optical fiber 1111 is inserted into the protective sleeve 1113, the open end of the protective sleeve 1113 is fitted around the outer periphery of the end of the connector 1120a away from the medical device 1200a, thereby preventing the optical fiber 1111 and the active material 1112 from being exposed. To securely fix the protective sleeve 1113 to the connector 1120a, the temperature sensor 1100a also includes a connecting sleeve, which is pressed against the outer periphery of the open end. The pressing deformation of the connecting sleeve tightens the flexible protective sleeve 1113, thus fixing the protective sleeve 1113 relative to the connector 1120a and preventing the protective sleeve 1113 from detaching.

[0109] In some embodiments, the body temperature sensor 1100a further includes a reinforcing sleeve. At the end of the connector 1120a furthest from the medical device 1200a, the fiber optic cable 1111 is thicker due to the protective sleeve 1113 and connecting bushing surrounding it, making the fiber optic cable 1111 prone to bending. By fitting the reinforcing sleeve around the connecting bushing and protective sleeve 1113, and ensuring the reinforcing sleeve is longer than the connecting bushing, bending of the fiber optic cable 1111 at the end of the connector 1120a furthest from the medical device 1200a can be prevented. It is understood that the reinforcing sleeve is made of a flexible material such as silicone.

[0110] In some embodiments, to prevent interference with magnetic resonance imaging, the body temperature sensor 1100a is made of a non-magnetic or weakly magnetic material. For example, the protective sleeve 1113 is made of materials such as PU, PVC, or TPU, and the connecting bushing is made of brass.

[0111] In some embodiments, the fiber optic temperature probe 1110 is at least 3m long to facilitate increasing the range of temperature measurement for patients.

[0112] This application also provides a body temperature sensor for use in a magnetic resonance imaging environment. The body temperature sensor includes an optical fiber body temperature probe, a connector and a calibration unit. Its structure and function are the same as those of the body temperature sensor 1100a in the body temperature measurement system 1000a provided in the above embodiment, and will not be described in detail here.

[0113] This application provides another body temperature measurement system 1000b for use in a magnetic resonance imaging environment. Please refer to [link to relevant documentation]. Figures 5 to 9 This includes a body temperature sensor 1100b and a medical device 1200b.

[0114] In some embodiments, the body temperature sensor 1100b includes a fiber optic body temperature probe 1110 and a processing unit 1140. The processing unit 1140 is used to transmit a first optical signal to the fiber optic body temperature probe 1110; the fiber optic body temperature probe 1110 is used to receive the first optical signal, generate a second optical signal based on the first optical signal, and send the second optical signal to the processing unit 1140; the processing unit 1140 is also used to receive the second optical signal and convert the second optical signal into an electrical signal; the body temperature sensor 1100b is also used to store calibration information of the fiber optic body temperature probe 1110; the processing unit 1140 is also used to obtain a body temperature measurement result based on the calibration information and the electrical signal; and the medical device 1200b is used to receive the body temperature measurement result.

[0115] Specifically, in some embodiments, the body temperature sensor 1100b includes a fiber optic body temperature probe 1110, a calibration unit 1130, a processing unit 1140, and a connector 1120b. The fiber optic body temperature probe 1110 includes an optical fiber 1111 and an active material 1112 disposed at a first end of the optical fiber 1111. The optical fiber 1111 is used to transmit a first optical signal and a second optical signal, and the active material 1112 is used to receive the first optical signal and transmit the second optical signal based on the first optical signal. The calibration unit 1130 is used to store the calibration information of the fiber optic body temperature probe 1110. The first end of the processing unit 1140 is connected to the second end of the optical fiber 1111. The processing unit 1140 includes a light-emitting circuit 1143, a receiving circuit 1144, and a processing circuit 1145. The light-emitting circuit 1143 is used to emit a first light signal to the active material 1112 through the optical fiber 1111. The receiving circuit 1144 is used to receive a second light signal emitted by the active material 1112 through the optical fiber 1111 and convert the second light signal into an electrical signal. The processing circuit 1145 is used to acquire calibration information and the electrical signal, and obtain the body temperature measurement result based on the calibration information and the electrical signal. The body temperature sensor 1100b is connected to the medical device 1200b through a connector 1120b. The first end of the connector 1120b is connected to the second end of the processing unit 1140, and the second end of the connector 1120b is connected to the medical device 1200b. The connector 1120b is used to transmit the body temperature measurement result calculated by the processing unit 1140 to the medical device 1200b.

[0116] In some embodiments, the medical device 1200b includes a processor 1210b and a display 1220. The processor 1210b is used to receive body temperature measurement results, and the display 1220 is used to display the body temperature measurement results.

[0117] During the body temperature measurement process using the body temperature measurement system 1000b provided in this application embodiment, the processing unit 1140 is disposed at the end of the body temperature sensor 1100b. At the end of the body temperature sensor 1100b, the light-emitting circuit 1143 of the processing unit 1140 emits a first light signal to the active material 1112 of the fiber optic body temperature probe 1110. The fiber optic cable 1111 transmits the first light signal to the active material 1112, thereby exciting the active material 1112 to emit a second light signal. The fiber optic cable 1111 then transmits the second light signal to the receiving circuit 1144 of the processing unit 1140. The receiving circuit 1144 receives the second light signal and converts it into an electrical signal. The calibration unit 1130 stores the calibration information of the fiber optic body temperature probe 1110. After the processing unit 1140's calculation circuit 1145 obtains the calibration information and the electrical signal, it obtains the body temperature measurement result based on the calibration information and the electrical signal. After obtaining the body temperature measurement result, it is output through the connector 1120b and displayed on the display 1220 of the medical device 1200b. In this embodiment, the body temperature measurement result is obtained at the body temperature sensor 1100b. Only the body temperature measurement result is transmitted between the body temperature sensor 1100b and the medical device 1200b, and no light signal is transmitted.

[0118] This application embodiment generates calibration information that is one-to-one matched with the fiber optic body temperature probe 1110 before leaving the factory and stores it in the body temperature sensor 1100b. At the same time, the processing unit 1140 is set at the end of the body temperature sensor 1100b, realizing a one-to-one binding between the fiber optic body temperature probe 1110 and the processing unit 1140. This allows signal processing to be completed at the end of the body temperature sensor 1100b. When the body temperature sensor 1100b in the body temperature measurement system 1000b is damaged and needs to be replaced, the user can directly replace it with a new body temperature sensor 1100b. This is simple and quick, ensuring high-precision measurement while also achieving calibration-free operation, saving the maintenance cost of returning the device for calibration. Users can replace the body temperature sensor 1100b immediately after it is damaged, improving the utilization rate of the body temperature measurement system 1000b. Meanwhile, the body temperature sensor 1100b and the medical device 1200b only transmit body temperature measurement results, which is more stable than optical signal transmission. Furthermore, when the connector 1120b of the body temperature sensor 1100b is plugged into or unplugged from the medical device 1200b, the optical fiber will not be exposed to the environment, thus avoiding the optical fiber from being contaminated by dust and impurities and affecting the measurement accuracy.

[0119] In some embodiments, the electrical signal is the attenuation time of the second optical signal. After receiving the second optical signal emitted by the active material 1112, the receiving circuit 1144 of the processing unit 1140 calculates the attenuation time of the second optical signal. The arithmetic circuit 1145 of the processing unit 1140 obtains the body temperature measurement result based on the calibration information and the attenuation time of the second optical signal.

[0120] In some embodiments, the calibration information includes a lookup table relating the body temperature measurement results of the fiber optic body temperature probe 1110 to electrical signals. The fiber optic body temperature probe 1110 is individually calibrated before leaving the factory, and multiple electrical signals are measured at multiple preset temperatures to obtain the lookup table relating the body temperature measurement results of the fiber optic body temperature probe 1110 to electrical signals.

[0121] It should be noted that the lookup table format is not limited. The lookup table between the body temperature measurement result and the electrical signal of the fiber optic body temperature probe 1110 can be obtained by directly mapping the electrical signal to a preset temperature, or by mapping the electrical signal to a temperature calibration difference. The body temperature measurement result obtained based on the calibration information and the electrical signal can be obtained by directly querying the lookup table based on the electrical signal, or it can be obtained by first calculating the baseline body temperature value based on the electrical signal, then querying the lookup table based on the electrical signal to obtain the temperature calibration difference, and finally obtaining the body temperature measurement result based on the baseline body temperature value and the temperature calibration difference.

[0122] In one embodiment, the fiber optic temperature probe 1110 is tested at multiple preset temperatures before leaving the factory. The attenuation time of the second optical signal emitted by the active material 1112 at each preset temperature is calculated to obtain a temperature-time correlation lookup table for the fiber optic temperature probe 1110. When the temperature sensor 1100b is connected to the medical device 1200b for temperature measurement, the processing unit 1140 of the temperature sensor 1100b obtains the attenuation time of the second optical signal. Based on the temperature-time correlation lookup table of the fiber optic temperature probe 1110, the corresponding temperature measurement result is obtained and then transmitted to the medical device 1200b for display.

[0123] It should be noted that the electrical signal can also be other optical signal parameters of the second optical signal, such as optical signal intensity, optical signal peak value, etc., as long as they can have a corresponding relationship with temperature, and there are no restrictions here.

[0124] It is understandable that calibration information can be not only a lookup table, but also a lookup formula, lookup graph, etc., as long as it can represent the correspondence between body temperature measurement results and electrical signals. There are no restrictions here.

[0125] In some embodiments, please refer to Figure 6 When connector 1120b is connected to medical device 1200b, processing unit 1140 is located outside of medical device 1200b. For easy connection, the interface for connecting medical device 1200b to connector 1120b is located on the surface of medical device 1200b. When it is necessary to replace temperature sensor 1100b, it is only necessary to simply plug and unplug temperature sensor 1100b, which is simple and quick.

[0126] In some embodiments, please refer to Figure 9 When connector 1120b is connected to medical device 1200b, processing unit 1140 is located inside medical device 1200b. That is, the interface of medical device 1200b that connects to connector 1120b is located inside medical device 1200b. Medical device 1200b has through holes on its surface, through which fiber optic temperature probe 1110 extends. When it is necessary to replace temperature sensor 1100b, the outer casing of medical device 1200b needs to be opened before inserting or removing temperature sensor 1100b.

[0127] In some embodiments, the processing unit 1140 includes a housing 1141 and a circuit board 1142. The circuit board 1142 is fixed to the housing 1141, and the circuit board 1142 is provided with a light-emitting circuit 1143, a receiving circuit 1144, and a processing circuit 1145. It is understood that there may be one or more circuit boards 1142, and the light-emitting circuit 1143, the receiving circuit 1144, and the processing circuit 1145 may be disposed on the same circuit board or on different circuit boards.

[0128] In some embodiments, please refer to Figure 7 and Figure 8 In order to connect the optical fiber 1111 to the processing unit 1140, the body temperature sensor 1100b also includes an optical fiber fixing structure 1150. The optical fiber fixing structure 1150 is a hollow structure. The second end of the optical fiber 1111 passes through the optical fiber fixing structure 1150. The first end of the processing unit 1140 and the second end of the optical fiber 1111 are connected through the optical fiber fixing structure 1150.

[0129] In some embodiments, the second end of the optical fiber 1111 is fixed to the optical fiber fixing structure 1150. It should be noted that the method of fixing the second end of the optical fiber 1111 to the optical fiber fixing structure 1150 is not limited. In one embodiment, the second end of the optical fiber 1111 passes through the optical fiber fixing structure 1150 and is then bonded and fixed to the optical fiber fixing structure 1150.

[0130] In some embodiments, the housing at the first end of the processing unit 1140 is provided with a first opening 1146, which is substantially aligned with the light-emitting circuit 1143 and the receiving circuit 1144 to facilitate the smooth transmission of optical signals. The first end of the optical fiber fixing structure 1150 is fixed to the first opening 1146. It is understood that the fixing connection between the first end of the optical fiber fixing structure 1150 and the first opening 1146 can be a threaded connection, a snap-fit ​​connection, an adhesive connection, etc., and is not limited here.

[0131] In some embodiments, to improve the transmission efficiency of the optical signal, the second end of the optical fiber 1111 is substantially aligned with the light-emitting circuit 1143 and the receiving circuit 1144 to achieve stable optical path coupling. It should be noted that the substantial alignment of the second end of the optical fiber 1111 with the light-emitting circuit 1143 and the receiving circuit 1144 can be aligned with the center of the optical fiber 1111 or may have slight deviations. It is understood that the relative positional relationship between the light-emitting circuit 1143 and the receiving circuit 1144 and the optical fiber 1111 is not limited to the manner described above, as long as the optical signal can be transmitted normally between the light-emitting circuit 1143 and / or the receiving circuit 1144 and the optical fiber 1111. For example, the light-emitting circuit 1143 and / or the receiving circuit 1144 can also be arranged perpendicular to the extension line of the optical fiber 1111, and the optical signal can be transmitted between the light-emitting circuit 1143 and / or the receiving circuit 1144 and the optical fiber 1111 through reflection by a glass plate or the like.

[0132] In some embodiments, in order to improve the transmission efficiency of optical signals, the end face of the second end of the optical fiber 1111 is substantially flush with the end face of the first end of the optical fiber fixing structure 1150.

[0133] In some embodiments, the fiber optic temperature probe 1110 further includes a protective sleeve 1113 with one open end. The inner diameter of the protective sleeve 1113 is larger than the outer diameter of the fiber optic cable 1111, and it can be fitted onto the outer periphery of the fiber optic cable 1111. The open end of the protective sleeve 1113 is connected to the second end of the fiber optic fixing structure 1150. The end of the protective sleeve 1113 near the active material 1112 is a closed end, which covers the active material 1112 to prevent the entry of liquids such as disinfectant and contamination of the active material 1112. The outer surface of the protective sleeve 1113 can also be designed to be smooth to prevent damage to the patient's temperature measurement site.

[0134] In some embodiments, since the fiber optic temperature probe 1110 comes into direct contact with the patient during temperature measurement, the protective sleeve 1113 is made of medical-grade polymer material and meets biocompatibility requirements. Simultaneously, the protective sleeve 1113 is made of a flexible material, allowing it to be bent while effectively protecting the fiber optic cable 1111. The material of the protective sleeve 1113 also supports cleaning, disinfection, and sterilization, ensuring patient health while protecting the active material 1112 from contamination.

[0135] In some embodiments, please refer to Figure 8After the optical fiber 1111 is inserted into the protective sleeve 1113, the open end of the protective sleeve 1113 is fitted onto the outer periphery of the second end of the optical fiber fixing structure 1150, thereby preventing the optical fiber 1111 and the active material 1112 from being exposed. In order to securely fix the protective sleeve 1113 to the optical fiber fixing structure 1150, the body temperature sensor 1100b also includes a connecting bushing 1160, which is pressed against the outer periphery of the open end. The pressing deformation of the connecting bushing 1160 squeezes the flexible protective sleeve 1113, thereby fixing the protective sleeve 1113 to the optical fiber fixing structure 1150 and preventing the protective sleeve 1113 from coming off.

[0136] In some embodiments, please refer to Figure 8 The body temperature sensor 1100b also includes a reinforcing sleeve 1170. At the second end of the optical fiber fixing structure 1150, because the outer periphery of the optical fiber 1111 is also covered by a protective sleeve 1113 and a connecting shaft sleeve 1160, this part is relatively thick, making the optical fiber 1111 prone to bending at the second end of the optical fiber fixing structure 1150. By fitting the reinforcing sleeve 1170 around the outer periphery of the connecting shaft sleeve 1160 and the protective sleeve 1113, and ensuring that the length of the reinforcing sleeve 1170 is greater than the length of the connecting shaft sleeve 1160, bending of the optical fiber 1111 at the second end of the optical fiber fixing structure 1150 can be prevented. It is understood that the reinforcing sleeve 1170 is made of a flexible material such as silicone.

[0137] In some embodiments, the housing at the second end of the processing unit 1140 has a second opening 1147, and the first end of the connector 1120b is fixed to the second opening 1147. It is understood that the fixed connection between the first end of the connector 1120b and the second opening 1147 can be a threaded connection, a snap-fit ​​connection, an adhesive connection, etc., and is not limited thereto. The connector 1120b includes a transmission circuit 1121, which passes through the second opening 1147 and is electrically connected to the circuit board 1142, thereby transmitting the body temperature measurement result obtained by the processing unit 1140 to the medical device 1200b.

[0138] In some embodiments, the calibration unit 1130 is disposed within the housing 1141 of the processing unit 1140. The calibration unit 1130 may be disposed on the same circuit board 1142 as the arithmetic circuit 1145, or it may be disposed on different circuit boards. It is understood that the calibration unit 1130 and the arithmetic circuit 1145 may be an integral unit, i.e., the same component performing different functions, or they may belong to different components.

[0139] In other embodiments, the calibration unit 1130 may also be disposed outside the housing 1141 of the processing unit 1140. For example, the housing 1141 is further provided with a third opening, through which the calibration unit 1130 is connected to the circuit board 1142 outside the housing 1141.

[0140] In some embodiments, to prevent interference with magnetic resonance imaging, the body temperature sensor 1100a is made of a non-magnetic or weakly magnetic material. For example, the protective sleeve 1113 is made of materials such as PU, PVC, or TPU, and the connecting bushing is made of brass.

[0141] In some embodiments, the fiber optic temperature probe 1110 is at least 3m long to facilitate increasing the range of temperature measurement for patients.

[0142] This application also provides a body temperature sensor for use in a magnetic resonance imaging environment. The body temperature sensor includes an optical fiber body temperature probe, a calibration unit, a processing unit, and a connector. Its structure and function are the same as those of the body temperature sensor 1100b in the body temperature measurement system 1000b provided in the above embodiment, and will not be described in detail here.

[0143] This application provides various body temperature measurement systems and body temperature sensors. By placing a calibration unit for calibrating fiber optic temperature probes at the body temperature sensor end, users can obtain a calibration unit that is one-to-one matched with the fiber optic temperature probe when replacing the body temperature sensor. This allows for rapid body temperature measurement results based on the information in the calibration unit, ensuring high-precision measurement while achieving calibration-free operation, saving the maintenance costs of factory calibration. Users can immediately replace and use the body temperature sensor after it is damaged, improving equipment utilization. When the processing unit of the body temperature measurement system is placed at the medical device end, the processing unit of the medical device can quickly read the calibration information to obtain the body temperature measurement result after replacing the body temperature sensor, without the need for factory calibration. When the processing unit of the body temperature measurement system is placed at the body temperature sensor end, the calibration information of the fiber optic temperature probe is also stored at the body temperature sensor end, and the body temperature measurement result is obtained directly at the body temperature sensor end. When the body temperature sensor in the body temperature measurement system is damaged and needs to be replaced, the user can directly replace it with a new body temperature sensor without the need for factory calibration.
