Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to an optical fiber conduction type blood oxygen collection device, a steering wheel and an automobile. Background Art

[0002] With the continuous development of modern medical technology, medical monitoring instruments have become an indispensable category of medical electronic instruments. Among the physiological parameters monitored, in addition to electrocardiogram, blood pressure, etc., the measurement of oxygen concentration in human blood, namely blood oxygen saturation, is also of great significance.

[0003] For example, when driving, people need to touch the steering wheel of the car in real time, so the steering wheel of the car will be improved to monitor the blood oxygen saturation in the human body. However, the position of the driver's hand holding the steering wheel will change slightly during the driving process, so in order to ensure the accuracy of the monitoring, multiple monitoring devices need to be set at different positions of the steering wheel, which will result in a high cost of the monitoring device. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of high cost of monitoring devices in the prior art, thereby providing a relatively low-cost fiber optic conduction blood oxygen collection device.

[0005] In order to solve the above technical problems, the present invention provides an optical fiber conduction type blood oxygen collection device, comprising:

[0006] A blood oxygen sensor, a spectrometer and multiple signal collection terminals connected by a signal, wherein the spectrometer is used to divide the light signal emitted by the blood oxygen sensor into multiple beams and transmit them to the corresponding signal collection terminals, and the signal collection terminals are used to receive the light signal sent by the spectrometer and the touch signal of the human body, and transmit the light signal back to the blood oxygen sensor after receiving the touch signal.

[0007] Furthermore, the light splitting device is a light splitter.

[0008] Furthermore, the blood oxygen sensor, the spectroscopic device and the signal collection end are connected via an optical fiber signal.

[0009] Furthermore, the signal collection end includes a first transmitting end and a first receiving end which are connected to each other.

[0010] Furthermore, the blood oxygen sensor includes a second transmitting end and a second receiving end. The optical signal sent by the second transmitting end is separated into multiple beams by the spectroscopic device and then transmitted to the corresponding first transmitting end respectively. After the touch signal is collected by the signal collection end, the received optical signal is transmitted back to the second receiving end through the first receiving end.

[0011] Furthermore, the thickness of the signal collection end is 0.1 mm-10 mm.

[0012] Furthermore, it also includes a circuit board connected to the blood oxygen sensor signal.

[0013] The present invention also provides a steering wheel, comprising the optical fiber conduction type blood oxygen collection device.

[0014] Furthermore, the blood oxygen collection device is arranged on a side of the steering wheel grip away from the human body's line of sight.

[0015] The invention also provides a car, comprising the steering wheel.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The optical fiber conduction type blood oxygen collection device provided by the present invention comprises: a blood oxygen sensor connected with a signal, a spectrometer and a plurality of signal collection terminals, wherein the spectrometer is used to divide the optical signal emitted by the blood oxygen sensor into a plurality of beams and transmit them to the corresponding signal collection terminals, and the signal collection terminals are used to receive the optical signal sent by the spectrometer and the touch signal of the human body, and transmit the optical signal back to the blood oxygen sensor after receiving the touch signal. The spectrometer divides a plurality of optical signals and transmits them to a plurality of signal collection terminals respectively, and the spectrometer is connected to the blood oxygen sensor so that the plurality of signal collection terminals can also realize the function of the blood oxygen sensor to collect the blood oxygen saturation in the human body. When the human body contacts the blood oxygen sensor or the signal collection terminal, the blood oxygen saturation in the human body can be monitored. The signal collection terminal is low in cost and easy to replace. Compared with setting a plurality of blood oxygen sensors, the setting of a plurality of signal collection terminals greatly reduces the cost.

[0018] 2. In the optical fiber conduction blood oxygen collection device provided by the present invention, the thickness of the signal collection end is 0.1mm-10mm. When the thickness of the signal collection end is within this range, the comfort level when the human body touches the signal collection end is optimal.

[0019] 3. In the steering wheel provided by the present invention, the blood oxygen collection device is arranged on the side of the steering wheel cover away from the human body's line of sight, so as to avoid the infrared light emitted by the blood oxygen sensor interfering with the driver's line of sight and causing danger.

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 As shown, an optical fiber conduction type blood oxygen collection device provided in this embodiment of the present invention includes: a signal-connected blood oxygen sensor 3, a spectrometer 7 and a plurality of signal collection terminals 8, wherein the spectrometer 7 is used to divide the optical signal emitted by the blood oxygen sensor 3 into multiple beams, and transmit the optical signal to the corresponding signal collection terminals 8, and the signal collection terminals 8 are used to receive the optical signal sent by the spectrometer 7 and the touch signal of the human body, and transmit the optical signal back to the blood oxygen sensor 3 after receiving the touch signal.

[0027] The blood oxygen sensor 3 is connected to the spectroscopic device 7 via a connecting line 6. The blood oxygen sensor 3 uses a medical-grade sensor, and the collected signal is stable. In this embodiment, the spectroscopic device 7 is a spectrometer. The spectrometer is also called an optical splitter, which is commonly used for coupling, branching and distribution of optical signals. The spectrometer is a special probe for signaling monitoring, which mainly realizes the collection of original signaling data. The spectrometer 7 is connected to the signal collection terminal 8. In the present embodiment, the number of the signal collection terminals 8 is 8. Of course, the number of the signal collection terminals 8 is determined according to actual needs. In the present embodiment, the optical signal is an infrared light signal. The infrared light signal emitted by the blood oxygen sensor 3 is transmitted to the spectrometer 7 through the signal collection terminal 8 arranged near the blood oxygen sensor 3. Then, the infrared light signal is distributed to each signal collection terminal 8 through the spectrometer 7. When a human body touches the blood oxygen sensor 3 or any one of the 8 signal collection terminals 8, the 8 signal collection terminals 8 receive the touch signal of the human body and immediately transmit the infrared light signal to the blood oxygen sensor 3. The blood oxygen sensor 3 is connected to an external device to analyze the collected signal. When the blood oxygen saturation concentration of the human body is low, an early warning is given in time, thereby real-time and continuous monitoring of the blood oxygen saturation in the human body is performed.

[0028] By adding the spectrometer 7 and 8 signal collection terminals 8, the 8 signal collection terminals 8 realize the function of the blood oxygen sensor 3. The cost of the 8 signal collection terminals 8 is much lower than that of the 8 blood oxygen sensors 3, thereby reducing the overall cost of the blood oxygen collection device.

[0029] The blood oxygen sensor 3, the spectroscopic device 7 and the signal collection terminal 8 are connected by optical fiber 11. The optical fiber 11 is in bundle form and has a thickness between 0.01 mm and 10 mm. It should not be too thick to affect the comfort of human body when touching.

[0030] The signal acquisition end 8 includes a first transmitting end 9 and a first receiving end 10 which are connected to each other. The blood oxygen sensor 3 includes a second transmitting end 4 and a second receiving end 5. The optical signal sent by the second transmitting end 4 is separated into multiple beams by the optical splitting device 7 and transmitted to the corresponding first transmitting end 9 respectively. After the signal acquisition end 8 collects the touch signal, the received optical signal is transmitted back to the second receiving end 5 through the first receiving end 10.

[0031] The number of signal acquisition terminals 8 is 8, that is, the number of first transmitting terminals 9 is 8, and the number of first receiving terminals 10 is 8. The first transmitting terminals 9 are arranged adjacent to the first receiving terminals 10. The optical fiber 11 is divided into two lines. Eight first transmitting terminals 9 are arranged on one line for transmitting infrared light signals, and eight first receiving terminals 10 are arranged on the other line for receiving infrared light signals. The infrared light signal emitted by the blood oxygen sensor 3 is transmitted to the nearby first transmitting terminals 9 through the second transmitting terminal 4. The first transmitting terminal 9 transmits the infrared light signal to the spectroscopic device 7. The spectroscopic device 7 distributes the infrared light signal to each first transmitting terminal 9. When the human body touches the second receiving terminal 5 or any one of the eight first receiving terminals 10 on the blood oxygen sensor 3, the first receiving terminal 10 immediately transmits the infrared light signal to the second receiving terminal 5 of the blood oxygen sensor 3 after receiving the human body's touch signal. The blood oxygen sensor 3 is connected to an external device to analyze the collected signal. When the blood oxygen saturation concentration of the human body is low, an early warning is given in time, thereby realizing the monitoring of the blood oxygen saturation in the human body.

[0032] The thickness of the signal collection terminal 8 is 0.1 mm to 10 mm. When the thickness of the signal collection terminal 8 is within this range, the comfort level when the human body touches the signal collection terminal 8 is optimal.

[0033] It also includes a circuit board 2 connected to the signal of the blood oxygen sensor 3. A circuit board 2 is also arranged on the connecting line 6, and the circuit board 2 mainly controls the blood oxygen sensor 3 to be turned on or off, so as to realize signal collection.

[0034] The present invention also provides a steering wheel, comprising the optical fiber conduction type blood oxygen collection device. In this embodiment, the blood oxygen collection device is arranged on the side of the steering wheel cover 1 away from the human body's line of sight, so as to avoid the infrared light emitted by the blood oxygen sensor 3 interfering with the driver's line of sight, thereby causing danger.

[0035] In this embodiment, the handle cover 1 is a circular rubber ring, and the diameter of the handle cover 1 is between 10 cm and 200 cm, depending on the diameter of the steering wheel.

[0036] The connecting wire 6 is pasted on the surface of the handle cover 1. The connecting wire 6 is a flexible wire. The blood oxygen sensor 3, the circuit board 2, and the light splitting device are arranged on the connecting wire 6. The second transmitting end 4 and the second receiving end 5 on the blood oxygen sensor 3 are welded on the connecting wire 6. The optical fiber 11 is also pasted on the handle cover 1. The outer wall of the handle cover 1 is wrapped with leather or carbon fiber cloth to protect the collection device on the handle cover 1.

[0037] Of course, the grip cover 1 can also be in a long strip shape and arranged on the sports equipment at a position where the hand or body can touch it.

[0038] The handle cover 1 can also be arranged on the handlebar of a bicycle, so as to monitor the blood oxygen saturation in the human body in real time when the person is pushing or riding the bicycle.

[0039] The invention also provides a car, comprising the steering wheel.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
