The light source sensing element 13 is a photoplethysmography sensing element (PPG Sensor), and the light source sensing element 13 emits red light and infrared light, and the blood oxygen concentration information can be obtained after measurement, but not limited thereto, and for example, the light source sensing element emits light of any frequency spectrum, and the blood oxygen concentration information can be obtained after measurement, which all belong to the scope of the light source sensing element described in the present application.
Referring to fig. 3A and fig. 3B, fig. 3A is a schematic side view of a cantilever member of the wrist blood oxygen concentration measuring device of fig. 2, and fig. 3B is a schematic side view of a setup process of the wrist blood oxygen concentration measuring device of fig. 2. Fig. 3A shows the cantilever 12, a torsion spring 16 is disposed at a first end 122 of the cantilever 12, and the torsion spring 16 is clamped inside a second abutting portion 112 (not shown) of the abutting portion 11, such that the first end 122 of the cantilever 12 is elastically pivoted to an end of the second abutting portion 112 of the abutting portion 11. The elastic pivot connection described in the present application is not limited to the torsion spring 16, for example: compression springs, leaf springs, other resilient materials, and the like, such as components or devices that can rebound between the two, are all within the scope of the resilient pivot described herein.
As shown in FIG. 3B, in the setup process of the wrist blood oxygen concentration measurement device 10, the cantilever 12 is first pulled away from the outside, as shown in state Q. Then, the second abutting member 112 having an arc shape abuts on the radius 53 of the wrist 50. Subsequently, the cantilever 12 is released, so that the cantilever 12 springs back to the P-state, and the light source sensing element 13 can be more conveniently and accurately attached to a radial artery region 54 of the inner side 51 of the wrist 50. The radial artery area 54 refers to the radial artery and the area adjacent to the radial artery, which can be used to measure the blood oxygen concentration information by using the light source sensing assembly 13, and is within the scope of the radial artery area described in the present application.
In addition, in order to make the measurement more accurate, the light source sensing element 13 is protruded on the inner surface 121 of the cantilever member 12, so that the light source sensing element 13 is easily attached to the radial artery region 54 of the inner side 51 of the wrist 50, and the error caused by an air layer (not shown) between the light source sensing element 13 and the radial artery region 54 is reduced. The light source sensing assembly is not limited to be disposed in a protruding manner, and if the cantilever member with a springback mechanism is disposed in the present application, the light source sensing assembly and the radial artery region have a certain degree of adhesion, so as to measure the blood oxygen concentration information.
For the information on the measured blood oxygen concentration of the radial artery, please refer to fig. 4A-4D. Fig. 4A shows the result measured by red light when the light source sensing element is disposed on the outer side of the wrist, and fig. 4B shows the result measured by red light when the light source sensing element is disposed on the radial artery area on the inner side of the wrist. The horizontal axis of the graph is time, and the vertical axis is light intensity. From the results shown in the figure, it can be seen that there is no significant pulsating signal (i.e., ac component) on the outer side of the wrist, and there is significant pulsating signal (i.e., ac component) in the radial artery region on the inner side of the wrist.
Fig. 4C shows the result of the light source sensing element disposed outside the wrist and measured by infrared light, and fig. 4D shows the result of the light source sensing element disposed in the radial artery region inside the wrist and measured by infrared light. The horizontal axis of the graph is time, and the vertical axis is light intensity. From the results shown in the figure, it can be seen that there is no significant pulsating signal (i.e., ac component) on the outer side of the wrist, and there is significant pulsating signal (i.e., ac component) in the radial artery region on the inner side of the wrist. Finally, the blood oxygen concentration can be calculated by the pulse signals (i.e. the AC components) of the red light and the infrared light (as shown in FIGS. 4B and 4D).
