Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a finger-ring pulse oximeter. Background Art

[0002] The oximeter is a medical device that measures the oxygen content in the human arterial blood. By monitoring the blood oxygen index, it is possible to understand whether the human respiratory and immune systems are normal. Blood oxygen saturation has become an important physiological indicator for daily monitoring in ordinary families. Existing oximeters usually use desktop multi-parameter monitors, handheld pulse oximeters, wrist oximeters and fingertip pulse oximeters; among them, the desktop multi-parameter monitor is large in size and not convenient to carry; the handheld pulse oximeter needs to be held in hand at all times for detection, and the hand cannot free up space for other work; the wrist oximeter needs to be connected to the corresponding instrument with a wire harness, which is suitable for hospitalized patients; the fingertip pulse oximeter is only used for point measurement, but it needs to clamp the fingers, and it will still occupy a large space between the fingers, resulting in a large separation between the fingers and inflexible work.

[0003] The existing ring-type blood oxygen probe is composed of a ring body, a translucent cover, a support, a main board, a battery, etc., and a connecting part is provided at the notch of the ring body. However, when the patient inserts his finger into the ring body during use, the finger is easy to fall off the ring when moving, and the finger will shake inside the ring body during wearing. The finger cannot be immediately in the best measurement position during measurement, and the patient needs to find the best measurement point by himself. The process of manually finding the measurement point will also prolong the measurement time and reduce the measurement efficiency; and its connecting part will also have abutting and squeezing force on the finger whose finger circumference exceeds the space of the ring body, and long-term wearing will easily cause indentation on the finger, and long-term use will affect the blood circulation of the finger, and congestion may occur in severe cases; therefore, the existing ring-type blood oxygen probe will not only cause discomfort to the patient's hand, but also easily lead to unstable measurement results, and thus it is difficult to ensure the accuracy of the measurement.

A finger pulse oximeter of the present application includes a finger ring body unit, and the finger ring body unit includes a finger ring body and a support body connected above the finger ring body; a cavity is provided inside the finger ring body; a limiting member for limiting the finger is connected to the outside of the finger ring body; an electronic module for processing data is connected inside the support body; the cover unit includes a cover body, and the cover body is arranged above the finger ring body and forms a sealed connection with the support body. In order to prevent the finger from detaching from the finger ring body, a limiting member is further connected to the outside of the finger ring body, which can further block and limit the finger, not only effectively preventing the finger from detaching from the cavity inside the finger ring body, but also further ensuring that the finger is positioned within the monitoring area in the cavity. And through the limiting effect of the limiting member, an all-round positioning of the finger inside the cavity of the finger ring body can be achieved, enabling fingers of different thicknesses to be accurately positioned immediately after entering the inside of the cavity, so that the finger is limited within an effective monitoring area, and the higher the degree of fit between the finger and the monitoring area, the higher the accuracy of detecting the finger.

The connecting piece is between the first annular piece and the second annular piece, and can jointly form a cavity with the first annular piece and the second annular piece to connect the side of the connecting piece facing the cavity to a soft sac, which shows a concave state when a finger with a circumference exceeding the preset value is inserted into the cavity. Under the cooperative action of the first annular piece and the second annular piece, the finger is limited within the monitoring area. There is also a notch at the bottom between the first annular piece and the second annular piece. Through the setting of the notch, the elastic expansion range between the first annular piece and the second annular piece can be further increased.

[0028] 5. As a preferred embodiment of the present invention, a convex platform protruding inward is provided inside the connecting piece. Through the convex platform, the inside of the connecting piece is divided into a connected cavity and an installation cavity. The support body includes a shell and a bottom plate connected to the shell.

[0029] In order to increase the connection between the connecting piece and the support body, a convex platform protruding inward is provided inside the connecting piece, so that a separated cavity and an installation cavity are formed inside the connecting piece. The cavity is located below the installation cavity for the finger to extend in and out, and the installation cavity is used to install the support body.

However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0050] In addition, in the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inner", "outer", "axial direction", "radial direction", "circumferential direction", etc. is based on the orientation or positional relationship shown in the drawings.

[0052] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "embodiment", "example", "an embodiment", "example" or "specific example", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0053] For a clearer explanation of the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the drawings of the specification.

[0054] The present utility model relates to a finger ring pulse oximeter, as Figures 1-8 shown, which includes a finger ring body unit 1. The finger ring body unit 1 includes a finger ring body 11 and a support body 12 connected to the finger ring body 11; a cavity 9 is provided inside the finger ring body 11; a limiting member 6 for limiting the finger is connected to the outside of the finger ring body 11; an electronic module 13 for processing data is connected inside the support body 12; a cover body unit 2 includes a cover body main body 21, and the cover body main body 21 is arranged above the finger ring body 11 and forms a sealed connection with the support body 12.

[0055] To prevent the finger from detaching from the ring body 11, a limiting member 6 is also connected to the outside of the ring body 11. By providing the limiting member 6, the limiting function of the limiting member 6 can also achieve the all-round positioning of the finger inside the cavity 9 of the ring body 11, so that fingers of different thicknesses can be immediately limited within the effective monitoring area once they enter the cavity 9. The higher the degree of fit between the finger and the monitoring area, the higher the accuracy of the detected data. Moreover, the limiting member 6 does not squeeze the finger, which can ensure a good sense of comfort while the finger is in the monitoring area of the cavity 9 and will not cause indentations on the finger.

[0056] It should be noted that preferably, the monitoring area is set at a lower position in the cavity 9.

[0057] Regarding the structure of the limiting member 6, without being limited by this application, any of the following implementation manners can be adopted:

[0058] Implementation manner 1: The limiting member 6 includes an elastic connecting band 7 connected to the outside of the ring body 11. The two ends of the connecting band 7 extend relatively along the outer circumference direction of the ring body 11 from the upper side of the ring body 11 and can cover the circumferential side of the ring body 11.

[0059] The limiting member 6 includes an elastic connecting band 7; the connecting band 7 can enclose the outside of the notch. The connecting band 7 has a first connecting end extending along the outer peripheral surface of the first ring member 1121 and connected to the first ring member 1121, and a second connecting end extending along the outer peripheral surface of the second ring member 1122 and connected to the second ring member 1122.

[0060] In this embodiment, the connecting belt 7 is elastic and has a U-shaped structure. The first connecting end of the elastic connecting belt 7 is connected from the upper side of the outer circumference of the first annular member 1121 and extends along the outer circumference of the first annular member 1121, and the second connecting end is connected from the upper side of the outer circumference of the first annular member 1121 and extends along the outer circumference of the first annular member 1121, so that the connecting belt 7 forms an encircling shape wrapped around the circumference of the finger ring body 11. The connecting belt 7 can cover most of the periphery of the finger ring body 11. The first purpose is to form a structure with the soft bag 3 inside the cavity 9 to surround the outer circle of the finger, ensure that the finger is in the monitoring area of ​​the cavity 9, further improve the positioning accuracy of the finger, and help improve the monitoring accuracy; second, it can further increase the expansion capacity of the cavity 9, so that fingers of different thicknesses can be extended in and out of the cavity 9; third, it can protect the bottom of the finger. Since the limiter 6 is located outside the finger ring body 11 to form a circle that wraps the finger ring body 11, the gap can be sealed, so that the entire finger ring body 11 is a closed structure. When the finger is squeezed by the elastic soft bag 3 inside the cavity 9, it will not leave the cavity 9 from the gap of the finger ring body 11, thereby further improving the positioning of the finger, so that the finger is always in the monitoring area of ​​the cavity 9, and further improving the detection accuracy and efficiency.

[0061] Furthermore, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a folding portion 20 is formed at the corresponding notch position between the first connecting end and the second connecting end of the connecting belt 7, so that the folding portion 20 is arranged opposite to the support body 12, and the folding portion 20 can be unfolded when the first annular member 1121 and the second annular member 1122 are in the expanded state.

[0062] like Figure 1 As shown, the outer side of the connecting belt 7 has a plurality of grooves inclined to the side of the connecting belt 7, the purpose is to reduce the sense of restraint of the connecting belt 7 on the fingers, so as to enhance the user's experience. In addition, the connecting belt 7 is provided with grooves, which can further reduce the weight of the connecting belt 7 and give the user a sense of lightness when wearing it.

[0063] A folding portion 20 is provided at a position on the bottom of the connecting band 7 corresponding to the notch. The distance between the two ends of the folding portion 20 in the radial direction of the cavity 9 gradually increases from the side away from the cavity 9 towards the side close to the cavity 9. The purpose of setting the folding portion 20 is that when a finger thicker than the preset finger circumference extends into the cavity 9, due to the deformation and outward expansion of the first annular member 1121 and the second annular member 1122 under the squeezing force of the finger, the folding portion 20 of the connecting band 7 can further increase the expansion range of the first annular member 1121 and the second annular member 1122 to both sides, thereby increasing the accommodation for fingers of different thicknesses, adapting to the wearing of fingers of different thicknesses, and further increasing the elastic force of the connecting band 7, ensuring that fingers of different thicknesses can be accurately locked in the monitoring area and further improving the accuracy of monitoring.

[0064] In addition, the distance between the first connection end and the second connection end gradually decreases from the side away from the notch to the side close to the notch. Thus, the connecting band 7 can closely adhere to the outer peripheral surface of the ring body 11, enhancing the wrapping of the first annular member 1121 and the second annular member 1122 of the ring body 11 and increasing the elastic force range of the first annular member 1121 and the second annular member 1122.

[0065] Embodiment 2: The limiting member 6 includes a limiting band with an adjusting portion connected to the outside of the ring body 11. The two ends of the limiting band extend relatively along the outer peripheral direction of the ring body 11 from the upper side of the ring body 11 and can wrap around the circumferential side of the ring body 11.

[0066] The limiting member 6 includes a limiting band. The limiting band 6 has a U-shaped structure. One end of the limiting band is fixedly connected to the first annular member 1121, and the other end of the limiting band is detachably connected to the second annular member 1122. The limiting band can enclose the outside of the notch and extend from the upper side of the outer periphery of the first annular member 1121 to the upper side of the outer periphery of the second annular member 1122.

[0067] As the limiting band in this embodiment, the difference between it and the connecting band 7 in the first embodiment above is that the limiting band in this embodiment may or may not have elasticity, elasticity is not necessary, and the limiting band in this embodiment has an adjusting portion for adjusting the tightness. One end of the limiting band can be connected to the upper side of the first annular member 1121, and the other end of the limiting band can be detachably connected to the upper side of the second annular member 1122, so as to realize that the limiting band can wrap around the circumference of the ring body 11 and the limiting band can surround outside the notch, which can not only increase the expansion range of the first annular member 1121 and the second annular member 1122 and further improve the elastic acting force of the ring body 11, but also prevent the finger from detaching from the cavity 9 and affecting the detection of blood oxygen concentration data.

[0068] Regarding the specific structure of the limiting band, it is not limited by this application. Based on the limiting band in Embodiment 2, any one of the following several embodiments can be adopted:

[0069] Embodiment 1: The first connection end of the limiting band can be fixedly connected to the first ring-shaped member 1121 and can extend along the outer peripheral surface of the first ring-shaped member 1121. The second connection end of the limiting band has an adjustment part, and a magic tape is pasted on the adjustment part. On the outer peripheral surface of the second ring-shaped member 1122, there is a connection area for connecting with the second connection end of the limiting band, and a sticking tape for sticking with the magic tape is connected in the connection area. By pasting the magic tape at different positions of the sticking tape in the connection area at the second connection end of the limiting band, the gap between the limiting band and the finger ring body 11 can be adjusted, so as to adjust the tightness of the limiting band to achieve the adaptation of the finger ring pulse oximeter to fingers of different thicknesses.

[0070] Embodiment 2: The first connection end of the limiting band can be fixedly connected to the first ring-shaped member 1121 and can extend along the outer peripheral surface of the first ring-shaped member 1121. The second connection end of the limiting band has an adjustment part, and a card slot is arranged in the adjustment part. On the outer peripheral surface of the second ring-shaped member 1122, there is a connection area for connecting with the second connection end of the limiting band, and a plurality of buckles for adaptively connecting with the card slot are connected in the connection area. By connecting the card slot at the second connection end of the limiting band with the buckles at corresponding positions, the gap between the limiting band and the finger ring body 11 can be adjusted, so as to adjust the tightness of the limiting band to achieve the adaptation of the finger ring pulse oximeter to fingers of different thicknesses.

[0071] The finger ring body unit 1 includes a finger ring body 11 and a support body 12 connected above the finger ring body 11. The finger ring body 11 has a cavity 9 for fingers to enter and exit. Preferably, a soft bladder 3 is connected in the cavity 9, and the soft bladder 3 is distributed on the inner peripheral surface of the finger ring body 11. The soft bladder 3 can form depressions of different degrees according to fingers of different finger circumferences. Further, the finger ring body 11 has a hollow cavity, which is configured to generate depressions of different degrees towards the hollow cavity when the soft bladder 3 is inserted into the cavity 9 by a finger with a finger circumference exceeding a predetermined value. Further, the soft bladder 3 increases the friction force in some areas of the inner peripheral surface of the finger ring body 11, which can improve the friction force between the soft bladder 3 and the finger in contact, ensure that the finger is not easily slipped out of the cavity 9, and further enhance the abutting and wrapping effect of the soft bladder 3 on fingers of different finger circumferences, so that the finger is limited in the monitoring area.

[0072] The soft capsule 3 can wrap the finger, enabling the finger to be stably positioned in the monitoring area, preventing the finger from shaking in the cavity 9, and avoiding the patient manually adjusting the position of the finger to find the best measurement point. Further, it can improve the positioning accuracy of the finger, the detection accuracy of the blood oxygen concentration of the finger, and the detection efficiency. Moreover, the soft capsule can wrap the finger, only wrapping the peripheral side of the finger without squeezing the finger, giving the finger a good sense of comfort, avoiding the squeezing of the traditional connecting piece on the finger resulting in finger indentations or even congestion, and improving the user experience.

[0073] Regarding the structure of the soft capsule 3, without being limited by this application, any of the following implementation manners can be adopted:

[0074] Embodiment 1: The soft capsule 3 includes a strip-shaped capsule body 4 connected to the inner wall of the ring body 11.

[0075] The soft capsule 3 includes a plurality of capsule bodies 4 connected to the inner peripheral surface of the ring body 11. The capsule body 4 includes an elastic capsule main body and a connecting ring surrounding the capsule main body; the capsule main body is connected to the cavity wall of the ring body 11 through the connecting ring, and the capsule main body has a connecting portion for first contacting the finger, so that a finger with a finger circumference exceeding a predetermined value is positioned in the monitoring area under the wrapping action of the connecting portion.

[0076] As Figure 3 shown, the capsule bodies 4 are arranged at least in three places around the inner peripheral surface of the ring body 11, respectively at the center of the upper wall of the ring body 11 and on both sides of the center of the upper wall of the ring body 11. The connecting portion of the capsule main body protruding towards the cavity 9 can first contact the finger. Since the capsule main body has elasticity, when a finger with a finger circumference exceeding the preset value is inserted into the cavity 9, it will present a sunken state, and finally ensure that the finger is in the lower monitoring area of the cavity 9. The connecting ring has a conical structure, the connecting ring has elasticity and a certain supporting force, and can play a certain supporting role for the connected capsule main body, ensuring that the connecting portion of the capsule main body that first contacts the finger has a certain elastic force on the finger, so as to ensure that the finger is positioned in the monitoring area and improve the positioning accuracy of the finger.

[0077] Preferably, the inside of the capsule main body can be filled with gas, or liquid, or elastic structural members. The elastic structural members include but are not limited to sponges, etc. It can also be just an empty structure without filling any substances, specifically determined according to actual needs, and will not be elaborated here.

[0078] The cavity 9 is connected to the inner circumference of the ring body 11 and has multiple capsules 4 to achieve multi-point coverage of the finger. The capsule 4 has an arc surface, which can increase the contact area with the finger, thereby further improving the coverage of the finger. The arc surface of the capsule body can ensure that the finger has a good sense of comfort when in contact with the finger, and will not make the finger feel a strong sense of pressure. It can adapt to long-term wear and increase the user experience.

[0079] Furthermore, the radial dimension of the capsule 4 gradually increases from the capsule body to the connecting ring.

[0080] In order to enhance the abutting force of the capsule 4 on the finger, avoid shaking of the capsule 4, and enhance the connection strength of the capsule 4 itself, the radial dimension of the capsule 4 is gradually increased from the capsule body, i.e., the side facing the finger, to the connecting ring, i.e., the side away from the finger. When a finger exceeding the predetermined finger circumference contacts the capsule body, the capsule body can be recessed inward, further improving the efficiency of quickly locking the finger in a specific monitoring area, avoiding shaking of the finger in the cavity 9 and inaccurate positioning, thereby improving measurement accuracy and efficiency.

[0081] In addition, it should be noted that the capsule 4 can also be configured as a plurality of long strips arranged in parallel at intervals on the inner circumference of the ring body 11 .

[0082] Embodiment 2: The soft capsule 3 includes a plurality of hemispherical protrusions 5 connected to the inner wall of the finger ring body 11 .

[0083] The soft capsule 3 includes an elastic soft capsule body and a wrapping connector; the soft capsule body is connected to the cavity wall of the finger ring body 11 through the wrapping connector; the soft capsule body has a wrapping portion for first contacting the finger so that the finger is positioned in the monitoring area under the wrapping effect of the wrapping portion.

[0084] The elastic soft bag body has a wrapping portion that preferentially contacts the finger. When a finger exceeding the preset finger circumference is inserted into the cavity 9, the finger will apply pressure to the soft bag 3, and the soft bag 3 will wrap the finger, so that the finger is locked in the monitoring area under the wrapping effect of the wrapping portion. The soft bag body covers at least a part of the inner circumference connected to the finger ring body 11. When the finger is thicker or the finger deviates from the monitoring area, the soft bag 3 can limit the finger and help the finger return to the monitoring area; in order to further increase the elastic force and supporting force of the soft bag body, the soft bag body is connected to the inner circumference of the finger ring body 11 through a wrapping connector that is also elastic. Since the wrapping connector itself can provide a certain elastic force to the soft bag body, the finger is confined in the monitoring area under the wrapping effect, thereby further improving the monitoring accuracy, ensuring the effectiveness of monitoring and improving the measurement efficiency.

[0085] Further, the wrapping connecting piece is connected to the upper wall of the finger ring body 11, extends from the center of the finger ring body 11 to opposite sides, and the thickness of the wrapping connecting piece gradually decreases from one side of the wrapping part to the center of the upper wall of the finger ring body 11.

[0086] As Figure 2 shown, the soft capsule 3 is connected to the inner upper wall of the finger ring body 11, and the soft capsule 3 is located at the center of the upper wall of the finger ring body 11. The cross-sectional shape of the wrapping connecting piece is a U-shaped structure. The soft capsule body is connected to the side of the wrapping connecting piece facing the cavity 9, and the soft capsule body and the wrapping connecting piece form a U-shaped structure, so that both ends of the soft capsule body in the radial direction of the cavity 9 have wrapping parts protruding towards the cavity 9, and the wrapping parts can first contact the finger. In order to avoid wrapping and squeezing the outside of the finger and causing a strong sense of compression on the finger, the thickness of the wrapping connecting piece gradually decreases from one side of the wrapping part of the finger ring body 11 to the center of the upper wall of the finger ring body 11, and the finger will not feel any sense of squeezing or compression, and the finger is in a comfortable state, so that the finger can be positioned in the monitoring area below the cavity 9 by moving downward.

[0087] It should be noted that since the monitoring area is set below the cavity 9, the finger needs to be located in the lower area of the cavity 9. Therefore, the soft capsule 3 needs to be connected to the upper area of the inner circumference of the finger ring body 11. The soft capsule body is connected to the inner circumferential surface of the finger ring body 11 through the wrapping connecting piece. In order to achieve a uniform wrapping effect on the finger, the wrapping connecting piece needs to be symmetrically distributed by extending from the center of the upper wall of the inner circumferential surface of the finger ring body 11 to both sides; in order to avoid discomfort of the finger, the thickness of the wrapping connecting piece gradually decreases from one side of the wrapping part to the center of the finger ring body 11, and the reaction force from the top decreases, thereby further enhancing the user experience.

[0088] Further, the capsule body 4 or the hemispherical protrusion 5 is a solid structure filled with an elastomer inside; or, the capsule body or the hemispherical protrusion 5 is an elastic structure with a hollow interior.

[0089] The inside of the capsule body 4 or the hemispherical protrusion 5 can be filled with gas, or liquid, or an elastic structural member. The elastic structural member includes, but is not limited to, sponge, etc. It can also be just a deflated structure without filling any substance, which is specifically determined according to actual needs and will not be elaborated here.

[0090] As a preferred embodiment, the finger ring body 11 includes a connecting member 111 having elasticity respectively and a ring member 112 connected to the connecting member 111; the ring member 112 includes a first ring member 1121 and a second ring member 1122; the first ring member 1121 and the second ring member 1122 enclose a cavity 9 with a notch; one side of the connecting member 111 facing away from the cavity 9 can be connected to the support body 12, and one side of the connecting member 111 facing the cavity 9 can be connected to the soft capsule 3.

[0091] As Figures 1-3 As shown, the ring member 112 of the finger ring body 11 is located below the connecting member 111, and the first ring member 1121 and the second ring member 1122 on both sides of the bottom notch of the ring member 112 are symmetrically distributed and can enclose a hollow cavity 9. Both the front side and the rear side of the cavity 9 have openings for the purpose of allowing fingers to extend in and out. The soft capsule 3 is arranged inside the cavity 9 to position the finger inside the cavity 9, so that the finger is in the monitoring area on the lower side of the cavity 9. And a limiting member 6 is arranged on the circumference surrounding the first ring member 1121 and the second ring member 1122 outside the cavity 9. The function of the limiting member 6 is to prevent a finger with a finger circumference exceeding the preset value in the cavity 9 from detaching from the notch out of the cavity 9.

[0092] The limiting member 6 is connected to the outside of the finger ring body 11 and can extend to surround the circumference of the first ring member 1121 and the second ring member 1122, thereby further increasing the accommodation space of the cavity 9 and increasing the accommodation of fingers with different thicknesses; secondly, since the finger is inside the cavity 9 and there is a notch below the cavity 9 to prevent a finger with a finger circumference exceeding the preset value from falling off from the notch, the limiting member 6 arranged outside the finger ring body 11 can not only provide support for the finger from the finger belly side, but also cooperate with the soft capsule 3 to position the finger, so that the finger is locked in the monitoring area, thereby improving the positioning accuracy of the finger.

[0093] Specifically, a convex platform 8 protruding towards the inside is arranged in the connecting member 111. Through the convex platform 8, the inside of the connecting member 111 is divided into a connected cavity 9 and an installation cavity 10; the support body includes a shell 121 and a bottom plate 122 connected to the shell 121; the shell 121 is connected to the inner wall of the installation cavity 10, and the bottom plate 122 is connected above the convex platform 8.

[0094] An installation cavity 10 is formed inside the finger clip body. The installation cavity 10 is located above the cavity 9 and can be connected to the cavity 9. A protruding convex platform 8 is connected to the inner wall of the installation cavity 10, which can make the convex platform 8. Through the convex platform 8, the inside of the finger ring body 11 is divided into a connected cavity 9 and an installation cavity 10; the support body includes a shell 121 and a bottom plate 122 connected to the shell 121; the shell 121 is connected to the inner wall of the installation cavity 10, and the bottom plate 122 is connected above the convex platform 8.

[0095] like Figure 6 As shown, one side of the support body has a charging terminal 24 protruding from the side wall of the support body, and a plurality of charging interfaces 19 are arranged on the charging terminal 24, which can adopt a magnetic charging structure or a socket charging structure, depending on actual needs. A charging slot 23 is arranged on the ring body 11 corresponding to the charging terminal 24. When in use, the support body is installed in the ring body 11, the bottom plate 122 of the support body is attached to the top of the boss 8, and the peripheral side of the shell 121 of the support body is attached to the inner wall of the mounting cavity 10 of the ring body 11. The charging terminal 24 extends out of the charging slot 23 through the charging slot 23 and can be exposed to the outside world, which is convenient for charging the ring pulse oximeter by magnetic attraction or socket.

[0096] As a preferred embodiment, the electronic module 13 includes a mainboard 131 and a battery 132 and a vibrator 133 connected in sequence below the mainboard 131; the bottom plate 122 has a mounting groove 14 to form a vibrator mounting position for mounting the vibrator 133; a battery mounting frame 15 is connected to the shell 121 to form a battery mounting position for connecting the battery 132; the surrounding side of the shell 121 is connected to a plurality of clips 16 protruding from the side wall, and the clips 16 have a clip groove to form a mainboard mounting position connected to the mainboard 131.

[0097] like Figure 7 As shown, the mounting groove 14 is recessed in the center of the bottom plate 122 and does not penetrate the top plate. When in use, the vibrator 133 is installed in the mounting groove 14; the battery mounting frame 15 is arranged on the peripheral side of the shell 121, and the battery mounting frame 15 can have a variety of shapes, which can be T-shaped or L-shaped. The purpose is to isolate the battery 132 from the bottom plate 122 by a certain distance. When in use, the battery 132 can be placed on the battery mounting frame 15; the peripheral side of the shell 121 is provided with diagonally arranged clips 16, and the clips 16 have L-shaped clip grooves. When in use, the four corners of the main board 131 are clipped and connected to the corresponding clip grooves, and the four sides of the main board 131 are clipped and connected to the shell 121 through the abutment of the clip grooves on all sides, so that the main board 131 is limited inside the shell 121.

[0098] In addition, the bottom plate 122 has a first installation groove 18 for installing a cable connecting the photoelectric emitter 171 and the main board 131, and a second installation groove 14 for installing a cable connecting the photoelectric detector 172 and the main board 131. The first installation groove 18 and the second installation groove are respectively located on both sides of the shell 121 and penetrate the bottom plate 122, so that the cable can extend from the lower side of the finger ring body 11 to the shell 121 above the finger ring body 11 to connect with the corresponding photoelectric emitter 171 or photoelectric detector 172.

[0099] As a preferred embodiment, the finger pulse oximeter further includes a sensor unit 17, and the sensor unit 17 includes a photoelectric emitter 171 and a photoelectric detector 172; the photoelectric emitter 171 is used to emit a measurement signal, and the photoelectric detector 172 is used to receive the measurement signal to detect the blood oxygen concentration; the photoelectric emitter 171 is connected inside the first annular member 1121, and the photoelectric detector 172 is connected inside the second annular member; or, the photoelectric emitter 171 is connected inside the second annular member 1122, and the photoelectric detector 172 is connected inside the first annular member.

[0100] It should be noted that the sensor unit includes at least one of a blood oxygen sensor, a blood pressure sensor, a blood glucose sensor, a temperature sensor, and an ECG sensor. In this application, the sensor unit preferably uses a blood oxygen sensor.

[0101] Specifically, the sensor unit 17 includes a photoelectric emitter 171 and a photoelectric detector 172; the first annular member 1121 is provided with a first connection cavity 26 corresponding to the monitoring area, and the first connection cavity 26 is used to install the photoelectric emitter 171; the second annular member 1122 is provided with a second connection cavity 27 corresponding to the monitoring area, and the second connection cavity 27 is used to install the photoelectric detector 172.

[0102] The working principle of the finger pulse oximeter is to adopt the photoelectric blood oxygen detection technology combined with the plethysmography technology. Two beams of different wavelengths (660nm red light and 905 / 940nm infrared light) are irradiated on the finger root of the human body through the photoelectric emitter 171, and the measurement signal is obtained by the photoelectric detector 172. The information obtained is processed by the electronic circuit and the microprocessor, and the measured result is displayed on the panel 22 described below of the finger pulse oximeter. Therefore, the photoelectric emitter 171 and the photoelectric detector 172 are symmetrically connected within the monitoring area.

[0103] As Figure 4 shown, the first connection cavity 26 and the second connection cavity 27 are symmetrically opened on both sides of the cavity 9 in the radial direction. The first connection cavity 26 and the second connection cavity 27 are located at a position slightly lower than the cavity 9 to ensure that they are within the monitoring area. Since the structures of the first connection cavity 26 and the second connection cavity 27 are the same, the structure of the first connection cavity 26 will be specifically described below as an example:

[0104] The cross-section of the first connection cavity 26 is in a T-shaped structure. The inside of the first connection cavity 26 forms a first cavity and a second cavity that are connected and are both in a cuboid shape. The first cavity of the first connection cavity 26 faces the cavity 9, and the second cavity faces away from the cavity 9. When in use, the photoelectric emitter 171 or the photoelectric detector 172 can be inserted obliquely from the first cavity into the second cavity, and then the first cavity is filled with sealant so that the photoelectric emitter 171 or the photoelectric detector 172 is embedded in the inner wall of the finger ring body 11.

[0105] It should be noted that when the photoemitter 171 is installed in the first connection cavity 26, the photodetector 172 needs to be installed in the second connection cavity 27. When the photoemitter 171 is installed in the second connection cavity 27, the photodetector 172 needs to be installed in the first connection cavity 26.

[0106] Furthermore, the bottom plate 122 has a first mounting groove 18 for threading the cable connecting the photoemitter 171 to the main board 131, and a second mounting groove 14 for threading the cable connecting the photodetector 172 to the main board 131.

[0107] The bottom plate 122 has a first mounting groove 18 for threading the cable connecting the photoemitter 171 to the main board 131, and a second mounting groove 14 for threading the cable connecting the photodetector 172 to the main board 131. The first mounting groove 18 and the second mounting groove are respectively located on both sides of the housing 121 and penetrate the bottom plate 122, so that the cable can extend from the inside of the lower side of the ring body 11 to the housing 121 above the ring body 11 and be connected to the corresponding photoemitter 171 or photodetector 172.

[0108] As a preferred embodiment, the cover unit 2 further includes a panel 22; the panel 22 is connected above the cover body 21, and the panel 22 has a display screen for displaying blood oxygen concentration data.

[0109] The inner side of the cover body 21 is hermetically connected to the support body above the ring body 11 through a rabbet structure 25.

[0110] As Figure 7 and Figure 8 shown, the cover unit 2 is connected above the ring body unit 1, and the cover body 21 of the cover unit 2 can seal the top of the ring body 11 of the ring body unit 1, so that the ring body unit 1 and the cover unit 2 form a closed structure. Specifically, a downwardly inclined guiding slope is formed on the circumferential side of the cover body 21, and the guiding slope can play a role in blocking the top surface of the ring body 11; one side of the cover body 21 facing the ring body 11 can be hermetically connected to the side of the support body facing the cover body 21 through the rabbet structure 25, so as to form a closed structure between the ring body unit 1 and the cover unit 2.

[0111] Furthermore, the rabbet structure 25 includes a stopper 251. A stopper 251 is convexly connected to the side of the cover body 21 facing the support body, and a stopper groove 252 corresponding to the stopper 251 is provided on the support body. The cover body 21 and the support body are hermetically connected through the cooperation of the stopper 251 and the stopper groove 252.

[0112] As Figure 8As shown in the figure, the rabbet structure 25 includes a stopper 251. A stopper 251 is convexly connected to one side of the cover body 21 facing the support body. The stopper 251 has an annular structure. The stopper 251 is coaxially connected to the bottom of the cover body 21. An annular stopper groove 252 is formed on the top surface of the support body. The stopper 251 can be adapted to the stopper groove 252. By installing the stopper 251 of the cover body 21 into the stopper groove 252, the cover body 21 and the support body are hermetically connected, thereby further realizing the hermetic connection between the cover unit 2 and the finger ring body unit 1. The rabbet structure 25 can effectively prevent external water flow or dust from entering the cover unit 2 or the finger ring body unit 1 through the gap between the cover unit 2 and the finger ring body unit 1, improve the monitoring accuracy, and extend the service life of the finger ring pulse oximeter.
