Description

A ring pulse oximeter

[0001] The present application claims priority to the Chinese patent application No. 202411072325.0, filed on August 6, 2024, and entitled "A ring pulse oximeter", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application belongs to the technical field of medical devices, and specifically relates to a ring pulse oximeter. BACKGROUND

[0003] An oximeter is a medical device for measuring the oxygen content in the arterial blood of the human body. By monitoring blood oxygen indicators, it can be determined whether the respiratory and immune systems of the human body are normal. Existing oximeters usually adopt a desktop multi-parameter monitor, a handheld pulse oximeter, a wrist-type oximeter, and a finger-clamp pulse oximeter. The desktop multi-parameter monitor has a large device size and is not convenient to carry. The handheld pulse oximeter needs to be held for detection, and the hands cannot be used for other work. The wrist-type oximeter needs to be connected to the corresponding instrument through a wire harness and is suitable for inpatient use. The finger-clamp pulse oximeter is only used for point measurement, and the fingers need to be clamped, which occupies space between the fingers and causes the fingers to be separated, so that the hands cannot work flexibly.

[0004] The existing ring oximeter device needs to balance the comfort of the wearer and also consider the stability of signal acquisition during long-term wear for monitoring blood oxygen. Users expect the oximeter device to be portable, small, and not to pressurize the ring. However, the blood oxygen signal acquisition depends on the photoelectric sensor, and the accuracy of the collected signal is affected by the external light environment. Therefore, the signal needs to be collected as close to the skin tissue as possible. The ring part of the ring oximeter device for installing the sensor needs a certain clamping force to clamp the measured finger. The traditional ring-type oximeter cannot simultaneously adapt to the needs of users with different finger circumferences and cannot consider the stability of sensor signal acquisition. Excessive clamping force will cause poor blood pressure circulation in the measured part. Therefore, users expect to have a ring-type oximeter device that is portable, light, and easy to adjust the tightness without excessive coverage of the fingers. SUMMARY

[0027] Due to the adoption of the above technical solutions, the beneficial effects achieved by the present application are:

[0028] 1. The present application relates to a finger ring pulse oximeter, comprising a finger ring assembly, the finger ring assembly comprising a finger ring with elasticity and a sensor; the sensor is arranged in the finger ring and is configured to detect blood oxygen saturation; the finger ring has a finger ring cavity for inserting a finger, and at least a part of the inner circumferential surface of the finger ring is connected with an elastic bag body; the elastic bag body can cause different elastic depressions according to different finger circumferences.

[0029] The finger ring has elasticity, which can accommodate fingers of different thicknesses entering the finger ring cavity, even if the finger exceeds the predetermined finger circumference, the finger can also enter the finger ring cavity to realize measurement; the finger ring with elasticity can provide a clamping effect for the finger, and at the same time, the local friction of the inner circumferential surface of the finger ring is moderately increased, which can form an adaptive adjustment to the inner circumferential surface of the finger ring, so that the inner circumferential surface of the finger ring appears different sizes according to the different finger circumferences; for example, when the finger circumference is thin, a smaller inner circumferential surface can be formed, and when the finger circumference is thick, a larger inner circumferential surface can be formed; the expanded inner circumferential surface provides more space for the finger, so that the finger can be more effectively fitted on the side, and the finger can be locked in the monitoring area to further ensure the clamping of the finger in the finger ring.

[0030] At least a part of the inner circumferential surface of the finger ring is connected with an elastic bag body, which can be used to clamp and cover the back of the finger inside the finger ring cavity, so that the finger is limited in the predetermined monitoring area under the uniform clamping effect. Thus, the fingers of different thicknesses can be limited in the monitoring area under the action of the elastic bag body as soon as they enter the finger ring cavity, and the fingers will not shake or deviate slightly in the finger ring cavity, realizing accurate positioning of the fingers. Therefore, it is not necessary to manually move the fingers to the monitoring area, avoiding the problem of inaccurate measurement and prolonged detection time caused by inaccurate positioning during manual movement. The monitoring area is also provided with a sensor for detecting the blood oxygen saturation of the finger, and the higher the fitting degree of the finger and the monitoring area, the higher the detection accuracy of the sensor in the monitoring area. Therefore, the finger ring pulse oximeter of the present application can automatically lock the finger into the monitoring area as soon as it is inserted, which can realize accurate positioning of the finger position, thereby improving the measurement accuracy, improving the detection efficiency, and improving the user experience.

[0031] Moreover, the presence of the elastic capsule does not cause any indentation to the finger entering the ring cavity, but only wraps the finger, moderately increasing the local friction, making the wearing process more comfortable, the finger ring pulse oximeter of the present application is more suitable for long-term wearing; The elastic ring adjusts the corresponding clamping force on the finger according to ergonomics, so that the finger is in a comfortable state, ensuring that the finger does not receive excessive pressure and is always in a relatively relaxed state. The elastic capsule designed in the present application limits the finger in the monitoring area, so that the finger can be stable in the monitoring area without any restraint, accurate data collection is realized, and accurate monitoring is realized.

[0032] 2. As an embodiment of the present application, the elastic capsule is a long strip-shaped protrusion connected to the inner circumferential surface of the ring, and the protrusion is provided on both sides of the extension direction of the elastic capsule, so that the finger is positioned in the monitoring area under the limiting action of the protrusion.

[0033] The elastic capsule has a protrusion that preferentially contacts the finger, which can wrap the back of the finger, so that the finger is returned to the monitoring area under the action of the protrusion. The elastic capsule is connected to at least part of the inner circumferential surface of the ring. When the finger is thick or the finger enters the position offset, not only the protrusion abuts against the outside of the finger, but the entire elastic capsule can be used to abut against the finger to help the finger return to position. The protrusion that first contacts the finger can more favorably abut against the finger. If the position of the finger inserted into the ring cavity deviates from the monitoring area, the protrusion can fully abut against the finger and quickly push the finger into the correct monitoring area, thereby further ensuring the effectiveness of the monitoring, reducing the monitoring time, and improving the monitoring accuracy.

[0034] 3. As an embodiment of the present application, the elastic capsule is connected to the inner circumferential surface of the ring, extends from the center of the ring to the opposite two sides, and the thickness of the elastic capsule gradually decreases from one side of the protrusion to the center of the upper wall of the ring.

[0035] In one scheme, the monitoring area can be arranged below the ring cavity, so the finger needs to be positioned in the lower area of the ring cavity, so the elastic capsule needs to be connected to the upper area of the inner circumferential surface of the ring. In order to achieve uniform wrapping and abutting of the finger, the elastic capsule is symmetrically distributed from the inner circumferential surface of the ring with the center line of the ring as the center. In order to avoid the finger feeling uncomfortable, the thickness of the connecting piece gradually decreases from one side of the protrusion to the center of the ring cavity, the wrapping effect from the top is reduced, thereby further enhancing the user experience.

[0036] 4. As an embodiment of the present application, the elastic capsule is a capsule structure with multiple spaced protrusions arranged on the inner circumferential surface of the ring, and the capsule structure has a circumferential portion and a top portion, so that the finger is positioned in the monitoring area under the limiting action of the top portion.

[0037] As another embodiment of the elastic bag, the elastic bag can be designed as a capsule structure, which is a semi-spherical structure with elasticity, and a plurality of semi-spherical structures are distributed along the inner wall of the ring to achieve multi-point contact with the finger and uniform pressing of the finger. The semi-spherical structure of the elastic bag can increase the contact area with the finger, thereby further improving the uniform covering of the finger, and the elastic effect of the semi-spherical elastic bag can increase the comfort of the finger when in contact with the finger, without causing compression of the finger. The elastic bag can be suitable for long-term wearing and improve user experience.

[0038] 5. As an embodiment of the present application, the radial size of the capsule structure gradually increases from the top to the peripheral portion.

[0039] In order to enhance the uniform covering of the elastic bag on the finger, avoid the shaking of the elastic bag itself, and enhance the connection strength of the elastic bag itself, the radial size of the elastic bag gradually increases from the top side to the peripheral portion. When the finger contacts the elastic bag, the elastic bag can cover the finger, avoid the shaking of the finger in the ring cavity, cause unstable monitoring, further improve the quick locking of the finger in a specific monitoring area, and improve the measurement accuracy and efficiency.

[0052] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0053] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other ways different from those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0055] In this application, unless specifically defined otherwise, the terms "mount", "connect", "connection", "fixed", and the like, should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection, and can also be communication; can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0056] In this application, unless specifically defined otherwise, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. In the description of the specification, the description of the terms "embodiment", "example", "one embodiment", "exemplary" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the description of the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0057] The present application relates to a finger ring pulse oximeter, as shown in Figures 1-8, comprising a finger ring assembly 1, the finger ring assembly 1 comprising a finger ring 11 with elasticity and a sensor; the sensor is arranged in the finger ring and is configured to detect blood oxygen saturation; the finger ring 11 has a finger ring cavity 5 for inserting a finger, at least part of the inner circumferential surface of the finger ring cavity 5 is connected with an elastic capsule 3, and the elastic capsule 3 can cause different elastic depressions according to different finger circumferences.

[0058] In the present application, it should be noted that the finger ring 11 is made of soft silicone material, the inner wall is smooth, which can enhance the comfort during wearing; and the finger ring has elasticity, which can adjust the clamping force on the finger to make the finger more comfortable, so as to be more in line with ergonomics; the lower side of the finger ring has an opening, which can further increase the elastic range of the finger ring to increase the containment of fingers with different finger circumferences, the adjustment range is wider, and it can adapt to the wearing of fingers with different finger circumferences.

[0059] In the present application, the monitoring area 26 is arranged at the lower side of the ring cavity 5, and the finger is inserted into the ring 11 of the ring assembly 1. Since the ring 11 is elastic, fingers of different thicknesses can be inserted. Since the inner circumferential surface of the ring 11 has an elastic capsule 3, the finger can be covered, so that the finger can be positioned in the monitoring area 26. The higher the adhesion of the finger to the monitoring area 26, the higher the accuracy of the sensor 2 in the monitoring area 26 in detecting the finger. The ring 11 is elastic, so that fingers of different thicknesses entering the ring cavity 5 have sufficient tolerance. The ring 11 with elasticity can apply a covering effect to the finger, and can push the finger to be locked to the monitoring area 26, further ensuring the clamping of the finger in the ring.

[0060] Further, the ring 11 can adjust the size of the inner circumferential surface according to different finger circumferences. For example, when the finger circumference is thin, the elastic capsule 3 forms a smaller inner circumferential surface to cover the finger and position the finger in the monitoring area 26. When the finger circumference is thick, the inner circumferential surface of the ring 11 forms a larger inner circumferential surface after the finger enters the ring cavity 5. The larger inner circumferential surface is relatively expanded compared to the inner circumferential surface of the thin finger, and provides more space for the finger, enhancing the comfort of wearing. Moreover, the larger inner circumferential surface can more effectively adhere to the side of the finger, ensuring that the finger is stably positioned in the monitoring area 26 while improving the stability of the monitoring, thereby improving the accuracy of the monitoring.

[0061] At least part of the inner circumferential surface of the ring 11 is connected with the elastic capsule 3, which can abut and cover the finger. The elastic capsule 3 can be elastically depressed to different degrees according to different finger circumferences. For example, when a thin finger and a thick finger enter the ring cavity 5, the elastic capsule 3 is depressed to different degrees. The thick finger can cause the elastic capsule 3 to be depressed to a greater degree. The finger is limited in the predetermined monitoring area 26 under the covering effect of the elastic capsule 3, and the finger does not shake or deviate slightly in the ring cavity 5, achieving accurate positioning of the finger. Therefore, the finger does not need to be manually moved to the monitoring area 26, avoiding the problem of inaccurate positioning during manual movement, inaccurate measurement, and prolonged detection time. The monitoring area 26 is also provided with a sensor for detecting the blood oxygen saturation of the finger. The higher the adhesion of the finger to the monitoring area 26, the higher the accuracy of the sensor in the monitoring area 26 in detecting the finger. Therefore, the ring pulse oximeter of the present application can automatically lock the finger to the monitoring area 26 as soon as the finger is inserted, accurately position the finger, improve the accuracy of measurement, improve the detection efficiency, and improve the user experience.

[0062] And the presence of the elastic capsule 3 will not cause any indentation to the finger entering the ring cavity 5, it just covers the finger, moderately increases the local friction, so that the wearing process is more comfortable, the finger ring pulse oximeter of the application is more suitable for long-term wearing; The elastic ring 11 will adjust the corresponding clamping force on the finger according to ergonomics, so that the finger is in a comfortable state, ensures that the finger will not be subjected to excessive pressure, and is always in a relatively relaxed state, the elastic capsule 3 designed in the application limits the finger in the monitoring area 26, so that the finger can be stably and accurately collected data without any restraint, and accurate monitoring is realized.

[0063] Further, the inside of the ring 11 is provided with a cavity, and the elastic capsule 3 is recessed in the cavity when the finger is inserted beyond the predetermined finger circumference. Through the cavity provided in the inside of the ring 11, when the finger circumference exceeds the predetermined range, the elastic capsule 3 has a compression space, so as to adapt to the detection of fingers with different finger circumferences, and improve the adaptation range of the finger ring pulse oximeter.

[0064] Further, the elastic capsule 3 has a certain elastic force, and after the finger is taken out of the ring 11, the elastically recessed elastic capsule 3 can return to the initial state in time. The elastic force makes the elastic capsule 3 not deformed, and can automatically rebound to the initial state after each use, which is beneficial to cyclic use and improves user experience.

[0065] Further, the elastic capsule 3 increases the friction force on the inner circumferential surface of the ring 11. By increasing the friction force of part of the elastic capsule 3, the friction force between the finger and the elastic capsule 3 can be indirectly increased, so that the comfort of the finger is ensured while the finger is protected from easily falling out of the ring cavity 5.

[0066] The structure of the elastic capsule 3 is not limited by the application, and any one of the following embodiments can be used:

[0067] Embodiment one: as shown in Figure 2, the elastic capsule 3 is a long strip protruding and connected to the inner circumferential surface of the ring, and the two sides of the extension direction of the elastic capsule have protruding parts 31, so that the finger is positioned in the monitoring area 26 under the limiting action of the protruding parts.

[0068] The elastic bag 3 has a protruding part 31 which first contacts the finger, and can cover and abut the outer part of the finger, so that the finger is returned to the monitoring area 26 under the action of the protruding part 31, and the elastic bag 3 covers at least part of the inner periphery connected to the ring 11. When the finger is thicker or the finger deviates from the detection area, not only the protruding part 31 abuts the outer part of the finger, but the entire elastic bag 3 can also be used to abut the finger to help the finger return to the correct position. The protruding part 31 can more effectively abut the finger, and if the finger deviates from the monitoring area 26 when it is inserted into the ring cavity, the protruding part 31 can sufficiently abut the finger and quickly push the finger into the correct monitoring area 26, thereby further ensuring the effectiveness of the monitoring, reducing the monitoring time, and improving the monitoring accuracy.

[0069] Further, the elastic bag 3 is connected to the inner periphery of the ring 11 and extends from the center of the ring 11 to the opposite sides, and the thickness of the elastic bag 3 gradually decreases from one side of the protruding part 31 to the center of the upper wall of the ring 11.

[0070] As shown in FIG. 2, the elastic bag 3 is connected to the center of the upper wall of the inner periphery of the ring 11 in an inverted U-shaped structure, and the protruding part 31 can first contact the finger, so the protruding part 31 can first abut and cover the finger. In order to achieve uniform covering and abutting of the finger, the elastic bag is symmetrically distributed about the center line of the ring from the inner periphery of the ring; in order to avoid full wrapping of the finger on one side, which makes the finger feel uncomfortable, and to ensure that the finger is in the lower monitoring area 26 of the ring 11, the thickness of the elastic bag 3 gradually decreases from one side of the protruding part 31 to the center of the upper wall of the ring 11. Different finger circumferences can be positioned in the lower monitoring area 26 of the ring 11 under the wrapping force of the protruding part 31, and the elastic bag 3 can correspondingly position and support the finger.

[0071] It should be noted that since the monitoring area 26 is arranged at the lower side of the ring 11, the finger needs to be positioned in the monitoring area 26 at the lower side of the ring 11 to ensure accurate monitoring, so the elastic bag 3 needs to be connected to the area above the inner periphery of the ring 11. Further, in order to achieve uniform wrapping of the back of the finger, the elastic bag 3 is connected to the center of the upper wall of the ring 11 and symmetrically distributed about the center of the ring 11.

[0072] In addition, it should be noted that the elastic bag 3 can also be configured as a plurality of long strips arranged in parallel on the inner periphery of the ring 11.

[0073] Embodiment two: as shown in FIG. 3, the elastic capsule 3 is in a plurality of spaced protrusions arranged on the inner circumferential surface of the ring 11, and the elastic capsule 3 has a circumferential portion and a top portion, so that the finger is positioned in the monitoring area 26 under the limiting action of the top portion.

[0074] As shown in FIG. 3, the elastic capsule 3 is arranged at least three places around the inner circumferential surface of the ring cavity 5, which are respectively located at the center of the upper wall of the inner circumferential surface of the ring 11 and on both sides of the center of the upper wall of the inner circumferential surface of the ring 11. The top portion of the elastic capsule 3 protruding towards the ring cavity 5 can first contact the finger, and since the elastic capsule 3 has elasticity, it can cover the back of the finger and the periphery of the finger, thereby ensuring that the finger is in the lower monitoring area 26 of the ring cavity 5. The top portion 32 first contacts the finger to pre-position the finger, thereby ensuring that the finger is positioned in the monitoring area 26 and improving the positioning accuracy of the finger.

[0075] Further, the inside of the elastic capsule 3 can be filled with gas, or liquid, or elastic structural members, including but not limited to sponge and the like, or just a hollow structure without filling any substance. The internal structure of the elastic capsule 3 is specifically determined according to actual needs, which is not described here.

[0076] The elastic capsule 3 is designed to have an elastic capsule structure, and the capsule structure is a hemispherical structure, and a plurality of capsule structures are distributed along the inner circumferential surface of the ring 11, achieving multi-point contact with the finger and achieving uniform contact with the finger; the elastic capsule 3 with a hemispherical structure can increase the contact area with the finger, thereby further improving the uniform covering of the finger; and the elastic force of the hemispherical elastic capsule 3 also increases the comfort of the finger when it is contacted, and does not cause the finger to appear squeezed and pressed, which can adapt to long-term wearing and increase user experience.

[0077] Further, the radial dimension of the elastic capsule 3 gradually increases from the top portion 32 to the circumferential portion.

[0078] In order to enhance the uniform covering of the elastic capsule 3 on the finger, avoid the elastic capsule 3 from shaking itself, and enhance the connection strength of the elastic capsule 3 itself, the radial dimension of the elastic capsule 3 gradually increases from one side of the top portion to one side of the circumferential portion. When the finger contacts the elastic capsule 3, the elastic capsule 3 covers the finger to avoid the finger from shaking in the ring cavity 5, which leads to unstable monitoring, further improves the finger to be quickly locked in a specific monitoring area 26, and can improve the measurement accuracy and efficiency.

[0079] As an implementation mode, as shown in FIG. 1, the ring 11 has a gap, the ring 11 includes the first finger clip 111 and the second finger clip 112 with elasticity arranged on both sides of the gap, and the first finger clip 111 and the second finger clip 112 enclose to form the ring cavity 5; the outer side of the first finger clip 111 and the second finger clip 112 is connected with the elastic connecting body 4 for limiting the palm side of the finger.

[0080] As shown in FIGS. 1-3, the bottom of the ring 11 is provided with a gap, the first finger clip 111 and the second finger clip 112 on both sides of the gap are symmetrically distributed and can enclose to form the internally hollow ring cavity 5, the front side and the rear side of the ring cavity 5 are both provided with an opening, which is convenient for the finger to enter and exit.

[0082] As an implementation mode, the sensor includes at least one of a blood oxygen sensor, a blood pressure sensor, a blood glucose sensor, a temperature sensor, and an ECG sensor.

[0083] Further, as shown in FIG. 1, the sensor in the present application is preferentially a blood oxygen sensor, the blood oxygen sensor includes a sensor light emitting end 21 and a sensor receiving end 22; the first finger clip 111 is provided with a first installation cavity 7 corresponding to the monitoring area 26, the first installation cavity 7 is used for installing the sensor light emitting end 21; the second finger clip 112 is provided with a second installation cavity 8 corresponding to the monitoring area 26, the second installation cavity 8 is used for installing the sensor receiving end 22.

[0088] The elastic connecting body 4 is not limited to the specific structure listed in the present application, and any one of the following embodiments can be used:

[0089] Embodiment one: as shown in FIG. 4, the elastic connecting body 4 includes an elastic connecting band 41; the connecting band 41 can be enclosed outside the notch, and the connecting band 41 has a first connecting end extending along the outer circumferential surface of the first finger clamp 111 and connected to the first finger clamp 111, and a second connecting end extending along the outer circumferential surface of the second finger clamp 112 and connected to the second finger clamp 112.
