[0040] The present invention provides a blood oxygen detection ring for cooperating with a blood oxygen host to measure the blood oxygen saturation of a person to be measured. During use, the blood oxygen detection ring can be worn on the finger of the person to be measured, and the blood oxygen detection ring connected to the blood oxygen host can transmit the measurement signal to the blood oxygen host for processing and / or display. Specifically, as Figures 1-4 shown, the blood oxygen detection ring 10 includes a wearing shell 100, a blood oxygen module 200 and a fitting structure. The wearing shell 100 is the support structure of the entire blood oxygen detection ring 10. The wearing shell 100 is annular, and the wearing shell 100 allows the finger of the person to be measured to pass through. The blood oxygen module 200 is the direct measurement part of the blood oxygen saturation of the person to be measured. The blood oxygen module 200 is disposed on the wearing shell 100, and the blood oxygen module 200 is used to measure the blood oxygen saturation of the blood in the finger of the person to be measured. The fitting structure is disposed on the wearing shell 100, and the fitting structure is used to keep the blood oxygen module 200 in close contact with the fitting structure.

[0041] For the above-mentioned blood oxygen detection ring 10, the blood oxygen module 200 is disposed on the wearing shell 100. After the finger of the person to be measured extends into the annular wearing shell 100, it can be within the measurement distance of the blood oxygen module 200, thereby realizing the basic function of measuring blood oxygen saturation. At the same time, the fitting structure is used to keep the wearing shell 100 in close contact with the finger of the person to be measured, so as to avoid the interference of external ambient light and ensure the measurement accuracy of the blood oxygen module 200 based on the optical principle for measuring blood oxygen saturation.

[0042] The wearing housing 100 serves as the support structure of the entire blood oxygen detection ring 10, which functions to support the blood oxygen module 200 and the fitting structure, thereby ensuring the accuracy of blood oxygen saturation measurement. Optionally, the wearing housing 100 is an integral structure or a split structure. As an achievable way, the wearing housing 100 adopts a split structure. As shown in Figures 1-4 FIG. 2, the wearing housing 100 includes an inner housing 120 and an outer housing 110. The inner housing 120 and the outer housing 110 are respectively annular. The inner housing 120 is detachably disposed inside the outer housing 110, and the inner housing 120 allows the finger of the person to be measured to pass through. The split-designed outer housing 110 and inner housing 120 facilitate the installation and fixation of the blood oxygen module 200 and the fitting structure. And a light-transmitting hole is formed on the inner housing 120. The blood oxygen module 200 is disposed between the inner housing 120 and the outer housing 110. The blood oxygen module 200 is opposite to the light-transmitting hole, and the blood oxygen module 200 can emit and / or receive measurement light through the light-transmitting hole. Further, the blood oxygen detection ring 10 further includes a light-transmitting window 500. The light-transmitting window 500 is disposed on the wearing housing 100. The light-transmitting window 500 is adapted to the light-transmitting hole and closes the light-transmitting hole. Thus, the light-transmitting window 500 covers the blood oxygen module 200. The light-transmitting window 500 can not only ensure the smooth emission and / or reception of the measurement light, but also prevent the person to be measured or other structures from contacting the blood oxygen module 200, thereby effectively protecting the blood oxygen module 200. At the same time, the fitting structure is disposed on the inner housing 120.

[0043] It can be understood that in the above embodiment, the positions of the light-transmitting hole and the light-transmitting window 500 correspond to the finger pulp of the person to be measured. In terms of implementation, the blood oxygen module 200 can adopt a transmissive or reflective type. The following embodiments will be described by taking the reflective blood oxygen module 200 as an example. And the reflective blood oxygen module 200 has the advantages of low power and longer standby time. In an embodiment of the present invention, as shown in Figure 2 and Figure 4 FIG. 3, the inner housing 120 includes an upper inner housing 121 and a lower inner housing 122. The upper inner housing 121 and the lower inner housing 122 enclose to form an annular shape. The upper inner housing 121 and the lower inner housing 122 are respectively detachably disposed inside the outer housing 110. The blood oxygen module 200 is disposed between the lower inner housing 122 and the outer housing 110. The light-transmitting hole is formed on the lower inner housing 122 and is closed by the light-transmitting window 500 at the same time. During the assembly process of the blood oxygen detection ring 10, first place the blood oxygen module 200 at the bottom of the outer housing 110, then sequentially install the lower inner housing 122 and the upper inner housing 121, and make the upper inner housing 121 abut against the lower inner housing 122. At the same time, install the light-transmitting window 500 at the light-transmitting hole.

[0044] The fitting structure is the key structure to ensure accurate measurement of blood oxygen saturation. In an embodiment of the present invention, the fitting structure includes a first fitting portion and a second fitting portion, which are respectively arranged on the inner side of the wearing shell 100. The first fitting portion is used to press the back of the finger of the person to be measured, and the second fitting portion is used to press the pulp of the finger of the person to be measured. When a reflective blood oxygen module 200 is adopted, the blood oxygen module 200 is arranged near the second fitting portion. When a transmissive blood oxygen component is adopted, the blood oxygen module 200 is arranged between the first fitting portion and the second fitting portion, and the light-emitting element in the blood oxygen module 200 is arranged near the second fitting portion, and the light-receiving element is arranged near the first fitting portion. The two fitting portions press the finger of the person to be measured from the two parts of the back of the finger and the pulp respectively, thereby effectively avoiding light leakage at the blood oxygen module 200.

[0045] Optionally, the first fitting portion and the second fitting portion can be solid structures, or structures such as holes or grooves formed in the solid structures, as long as they can press the finger from the two parts of the back of the finger and the pulp respectively. In an embodiment of the present invention, as Figures 1-2 and Figure 5 shown, the first fitting portion includes a gasket 300, which is detachably arranged on the inner side of the wearing shell 100. The second fitting portion is a receiving groove 400 formed on the inner side of the wearing shell 100, and the receiving groove 400 is used to receive the pulp of the finger of the person to be measured. The shape of the receiving groove 400 can be one or a combination of several of a rectangle, a circle, a sphere, a V shape, a pyramid shape, etc. For example, the receiving groove 400 is integrally rectangular, and at the same time, the bottom of the receiving groove 400 is designed as a circular arc concave surface. The gasket 300 and the receiving groove 400 are arranged opposite to each other, and the gasket 300 is used to press the back of the finger of the person to be measured. Specifically, the gasket 300 is fixed on the inner side of the upper inner shell 121, and grooves are respectively formed at the positions of the outer shell 110 and the lower inner shell 122 opposite to the gasket 300. The groove on the lower inner shell 122 is accommodated in the groove of the outer shell 110 and together forms the receiving groove 400. The blood oxygen module 200 is placed between the bottom of the receiving groove 400 on the outer shell 110 and the bottom of the receiving groove 400 on the lower inner shell 122. A light-transmitting hole is formed at the bottom of the receiving groove 400 of the lower inner shell 122 and is closed by a light-transmitting window 500.

[0046] On the basis of the above embodiment, further, as Figure 5As shown, the first fitting portion includes a plurality of pads 300. The thickness, width, and / or curvature between the plurality of pads 300 are different. The plurality of pads 300 are respectively detachably disposed on the inner side of the wearing housing 100, and each pad 300 is adapted to a finger of a different size. Medical staff can select a suitable pad 300 according to the specific size of the finger of the person to be measured, thereby ensuring the close fit between the wearing housing 100 and the finger of the person to be measured. Further, the pad 300 includes an installation protrusion 320 and a pressing liner 310. The pressing liner 310 is arc-shaped or circular, and the installation protrusion 320 is fixedly disposed on the edge of the pressing liner 310. An installation groove is formed on the inner side of the wearing housing 100, and the installation groove is adapted to the installation protrusion 320, and the installation groove accommodates the installation protrusion 320. For example, the pressing liner 310 is saddle-shaped, C-shaped or circular, as Figures 6-8 shown, the number of the installation protrusions 320 is four, and the four installation protrusions 320 are spaced apart and jointly fix the pressing liner 310. Correspondingly, on the upper inner shell 121, four adapted installation grooves are formed. In other embodiments, the pad 300 may also be other structures that can play a role in tightening.

[0047] In the above embodiment, the pad 300 can be made of a soft material such as silica gel. The soft and replaceable pad 300 is used to adapt to the finger circumference, so that the finger fits closely with the blood oxygen module 200 comfortably. In addition, due to the certain curvature of the human finger joint at the finger pulp, the accommodating groove 400 can effectively prevent the situation where the middle of the finger pulp is in good contact while there are gaps on both sides. When wearing, the finger pulp of the finger sinks into the concave area, effectively avoiding the light interference caused by the external environmental light entering. In other embodiments, the pad 300 may also be made of a harder material. At the same time, the cooperation between the pad 300 and the upper inner shell 121 can also be bonded by glue or tape, or can also be mechanical fixing methods such as snaps, pins, and screws.

[0048] In an embodiment of the present invention, as Figures 1-2 and Figure 4 shown, the blood oxygen detection ring 10 further includes a control module 600, and the control module 600 is electrically connected to the blood oxygen module 200. An opening structure is provided on the outer shell 110, and the control module 600 is disposed at the opening of the outer shell 110. The wearing housing 100 further includes a top shell 130, and the top shell 130 is detachably covered on the opening of the outer shell 110. As a feasible way, the control module 600 includes a battery and a control board, and the control board is electrically connected to the battery and the blood oxygen module 200 respectively. In other embodiments, the blood oxygen detection ring 10 may further include a wireless communication module, and the wireless communication module is electrically connected to the control board and can wirelessly connect and communicate with the blood oxygen host. Or the wireless communication module can also be integrated in the control board.

[0049] During the use of the blood oxygen detection ring 10 in the above-mentioned various embodiments, first, the blood oxygen module 200 is assembled at the bottom of the housing 110, and then the lower inner housing 122 with the light-transmitting window piece 500 pasted on it is used to press the blood oxygen module 200. Then, the upper inner housing 121 is used to press the lower inner housing 122, and the battery and the control board in the control module 600 are placed at the opening of the housing 110. Finally, the top shell 130 is pasted at the opening of the housing 110. The light-transmitting window piece 500 covers the blood oxygen module 200, and light can be emitted and incident through the light-transmitting window piece 500. When wearing, a cushion 300 with a suitable thickness is selected and installed on the upper inner housing 121, and then it can be worn in the way of an ordinary ring. It should be noted that the light-transmitting window piece 500 faces the finger pulp. The blood oxygen module 200, as an optical sensor, is very sensitive to the influence of ambient light. The ring-shaped blood oxygen detection ring 10 provided by the above-mentioned various embodiments. Compared with the traditional device for measuring blood oxygen, it is thin, light, small and portable, realizing home use and wearability. The signal collected by the ring is transmitted wirelessly to the remote blood oxygen host. The product form is ring-shaped and worn on the finger pulp, without occupying the fingertip and not affecting daily activities.

After the finger of the person to be measured extends into the ring-shaped wearing shell, it can be within the measurement distance of the blood oxygen module, thereby realizing the basic function of measuring blood oxygen saturation. At the same time, the cushion is used to keep the wearing shell in close contact with the finger of the person to be measured, making the pressing of the blood oxygen detection ring on the finger more stable. The accommodating groove can adapt to the shape of the finger pulp, thereby avoiding the interference of external ambient light and ensuring the measurement accuracy of the blood oxygen module for measuring blood oxygen saturation based on the optical principle.

[0051] Correspondingly, an embodiment of the present invention further provides a monitoring system, including a blood pressure measuring instrument and a blood oxygen measuring instrument. The blood oxygen measuring instrument includes a blood oxygen host and the blood oxygen detection ring 10. The blood oxygen detection ring 10 and the blood oxygen host are connected. In other embodiments, the monitoring system may further include other measuring instruments for measuring human health parameters.
