[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0014] See also Figure 1 and Figure 2 , a cross-sectional view and a combination view of blood oxygen monitoring. As shown in the figure, the blood oxygen monitoring device 1 of this embodiment includes a controller 11, a probe 13 and an optical fiber monitoring tube 15. The controller 11 is connected to the probe 13, the probe 13 has a first identification element 131, and the optical fiber monitoring tube 15 has a second identification element 151. The first identification element 131 identifies the second identification element 151 and generates an identification result. The controller 11 obtains an adjustment value according to the identification result, and adjusts the detection data of the blood detected by the probe 13 through the optical fiber monitoring tube 15 according to the adjustment value, so that the controller 11 obtains the detection result after calculating the adjustment value and the detection data. This embodiment can appropriately correct the detection error caused by the structure or material of the optical fiber monitoring tube and other external factors through the adjustment value, and obtain more accurate blood oxygen data detection results.

[0015] In this embodiment, the controller 11 is a blood oxygen saturation and hematocrit monitoring system. This monitoring system can continuously monitor the blood flowing in the optical fiber monitoring tube 15, and the controller 11 can display the relevant test results in real time. The test data includes blood oxygen saturation, hematocrit value and / or blood temperature. The controller 11 is connected to the probe 13. The probe 13 includes a transmitting optical fiber 133 and a receiving optical fiber 135. The transmitting optical fiber 133 is arranged on one side of the receiving optical fiber 135. The transmitting optical fiber 133 can emit a light source of a specific wavelength. This light source will be absorbed by the oxygenated hemoglobin and deoxygenated hemoglobin in human blood, and the intensity of the penetrating light of the specific wavelength light source will change with the physical phenomenon of the concentration of oxygenated hemoglobin and deoxygenated hemoglobin. The receiving optical fiber 135 will measure the concentration change signal of the oxygenated hemoglobin and deoxygenated hemoglobin in human blood. The controller 11 converts the blood oxygen concentration through proportional conversion or calculates it according to the definition formula of blood oxygen concentration. There are multiple transmitting optical fibers 133, so that the light source can completely illuminate the blood under test, thereby avoiding the influence of blind angles of the light source on the test results.

[0016] Furthermore, the probe 13 is assembled on the optical fiber monitoring tube 15, and the first identification element 131 of the probe 13 corresponds to the second identification element 151 of the optical fiber monitoring tube 15. The first identification element 131 is used to identify the second identification element 151 to obtain an identification result. This identification result includes the calibration parameters of the optical fiber monitoring tube 15. In this embodiment, the second identification element 151 is an electronic tag, and the electronic tag is a wireless radio frequency identification, a two-dimensional code or a bar code. The first identification element 131 is determined according to the specifications of the second identification element 151, and the first identification element 131 is an electronic tag reader, which is used to read the information of the second identification element 151. The electronic tag reader is a wireless radio frequency identification (RFID) tag reader, a two-dimensional code reader or a bar code reader. This embodiment does not limit the specifications of the electronic tag reader and the corresponding electronic tag, which are adjusted according to the needs of the user.

[0017] In addition, the probe 13 is assembled to the optical fiber monitoring tube 15, and the optical fiber monitoring tube 15 further includes a first fixing member 159, and the probe 13 further includes a second fixing member 137, and the first fixing member 159 and the second fixing member 137 are fixed to each other. In this embodiment, the probe 13 is installed around one end of the optical fiber monitoring tube 15 and has a second fixing member 137 protruding outward, and two first fixing members 159 are arranged on the outer wall of the optical fiber monitoring tube 15, and the two first fixing members 159 have corresponding notches on the opposite surfaces, so that the second fixing member 137 of the probe can be fixed in the notches of the two first fixing members 159 of the optical fiber monitoring tube 15. In this way, the probe 13 and the optical fiber monitoring tube 15 can be firmly combined, and the detection process will not affect the detection result due to the loose structure of the probe 13 and the optical fiber monitoring tube 15.

[0018] In this embodiment, the optical fiber monitoring tube 15 includes a body 153, and the body 153 has a detection channel 1531 and a detection port 1533. The detection port 1533 is located at one side of the detection channel 1531. The transmitting optical fiber 133 and the receiving optical fiber 135 of the probe 13 both correspond to the detection port 1533. In addition, the optical fiber monitoring tube 15 also includes a light-transmitting mirror 155 and a reflecting surface 157. The light-transmitting mirror 155 is located at the detection port 1533. The light-transmitting mirror 155 can transmit the specific light source emitted by the transmitting optical fiber 133 and the light source received by the receiving optical fiber 135 from the detection channel 1531. The light-transmitting mirror 155 has little effect on the light source passing through. The reflecting surface 157 is located on the inner wall of the detection channel 1531 corresponding to the detection port, so that the light intensity of the light source to be fed back to the receiving optical fiber 135 by the detection channel 1531 can be enhanced. In other words, it is beneficial to improve the detection signal intensity received by the receiving optical fiber 135. In this embodiment, the detection channel 1531 of the optical fiber monitoring tube 15 is used to connect to the extracorporeal circulation pipeline 2. When the extracorporeal circulating blood flows through the pipeline 2 and passes through the detection channel 1531 of the optical fiber monitoring tube 15, the blood oxygen level in the blood flowing through the optical fiber monitoring tube 15 can be detected. The extracorporeal circulation machine includes an extracorporeal membrane oxygenation system (ECMO) and an artificial heart-lung machine (Heart-Lung Maschine).

[0019] See also Figure 3 , is a block diagram of the blood oxygen monitoring method of the present application. As shown in the figure, in this embodiment, a blood oxygen monitoring device 1 is used to perform blood oxygen monitoring. After the optical fiber monitoring tube 15 is connected to the extracorporeal circulation pipeline 2, the steps of starting blood oxygen monitoring are as follows:

[0020] Step S1: Install the optical fiber monitoring tube 15 on the probe 13.

[0021] Step S2: The first identification element 131 identifies the second identification element 151 and generates an identification signal, and the first identification element 131 transmits the identification signal to the controller 11. The identification signal is a calibration parameter of the optical fiber monitoring tube.

[0022] Step S3: The controller 11 obtains the adjustment value according to the identification signal. The controller 11 has a built-in database, which contains calibration parameters of the optical fiber monitoring tube 15 and relevant information such as its corresponding material or structure, and provides an adjustment value corresponding to the correction test result according to the above relevant information. In this way, the controller 11 searches for the corresponding adjustment value in the database according to the calibration parameters of the optical fiber monitoring tube 15.

[0023] Step S4: The probe 13 detects the blood flowing through the optical fiber monitoring tube 15 and generates a detection signal, which is transmitted to the controller 11. The detection signal is a light source of a specific wavelength emitted by the transmitting optical fiber 133 and passes through the blood. The receiving optical fiber 135 measures the change of the light source in the blood and obtains an electrical signal using photoelectric conversion technology.

[0024] Step S5: The controller 11 processes the detection signal to obtain the detection data. The detection data is converted into blood oxygen concentration through proportional conversion or calculated according to the definition formula of blood oxygen concentration. However, the detection data is affected by the material or structure of the optical fiber monitoring tube 15, resulting in deviation of the detection data and insufficient accuracy.

[0025] Step S6: The controller 11 makes adjustments based on the detection data and the adjustment value to obtain the detection result. In this embodiment, the adjustment value can appropriately correct the influence of the blood oxygen value detected by the optical fiber monitoring tube 15, so as to obtain more accurate blood oxygen data.

[0026] In summary, the present application provides a blood oxygen monitoring device and a blood oxygen monitoring method, wherein the blood oxygen monitoring device can continuously monitor the blood in the optical fiber monitoring tube to obtain blood oxygen data. At the same time, during the above blood oxygen monitoring process, after the calibration parameters of the optical fiber monitoring tube are identified by the controller, the controller searches for the corresponding adjustment value in the database according to the calibration parameters of the optical fiber monitoring tube. In this way, the adjustment value can appropriately correct the numerical influence of the blood oxygen detected by the optical fiber monitoring tube, and more accurate blood oxygen data can be obtained.
