It is to be understood that the portion of the band 200 located in the groove 116 is non-detachably or detachably fitted to the first clamping body 11, which is not particularly limited in the present application. The non-detachable manner includes integrally forming the band with the first clamping body 11 or fixing the band with the first clamping body 11 in the groove 116 by gluing, etc. to increase the stability between the band 200 and the first clamping body 11. The detachable mode includes using a hook and loop fastener or a snap fastener or directly sleeving the hidden groove 116 to facilitate the replacement of the binding band 200.

The surface of the second clamping body 12 facing away from the first clamping body 11 is convexly provided with a positioning ring 125, the bandage 200 passes through the positioning ring 125 to be wound on the second clamping body 12 and the first clamping body 11, the positioning ring 125 defines and fixes the bandage 200, and the bandage 200 is prevented from being displaced and falling off. Specifically, the positioning ring 125 is located at one end of the second clamping body 12 near the bending section 13, and the width of the positioning ring 125 is not less than the width of the binding band 200, so that the binding band 200 can easily pass through the positioning ring 125. Further, a retaining ring 125 is disposed in correspondence with the groove 116 to retain the strap 200 together. In this embodiment, the positioning ring 125 is integrally formed with the mounting seat 121.

Specifically, the rotating shaft 202 is rotatably fitted on the positioning ring 125 of the second clamping body 12. Further, the rotating shaft 202 includes a first end and a second end, which are oppositely disposed, the first end is rotatably assembled in the positioning ring 125, the second end extends out of the positioning ring 125, and the adjusting knob 202 is fixed on the outer surface of the second end, so that the rotating shaft 202 is rotated by rotating the adjusting knob 205, thereby adjusting the binding band 200. In this embodiment, the adjusting knob 205 is located at the end of the rotation shaft 202 away from the opening of the elastic clamping cavity 14, so that when the finger is located in the elastic clamping cavity 14, the adjusting knob 205 will not press the skin near the finger.

Referring to fig. 4, in the second embodiment of the blood oxygen probe 100 of the present embodiment, the difference from the first embodiment is that the strap 200 includes a winding section 210 and a fixing section 220 extending from one end of the winding section 210. The winding section 210 is wound around the outer surface of the gripping head 10, and the fixing section 220 is at least partially wound around the winding section 210. Specifically, the winding section 210 includes a first surface 211 and a second surface 212 that are oppositely disposed. When the winding section 210 is wound around the gripping head 10, the first surface 211 is attached to the outer surface of the gripping head 10. The fixing section 220 includes a third surface 221 located on the same surface as the first surface 211, and when the fixing section 220 is wound on the winding section 210, the third surface 221 is attached to the second surface 212. Wherein, the winding section 210 and the fixing section 220 are integrally formed by silica gel. It will be appreciated that the strap 200 may be integrally formed with the gripping head 10 when the gripping head 10 is also made of silicone.

It will be appreciated that in other embodiments of strap 200 of the present embodiment, wrapping section 210 includes a U-shaped cavity that receives gripping head 10. Specifically, first surface 211 is the surface matched with U profile with the surface of holding head 10, when using bandage 200, can directly overlap winding section 210 at the surface of holding head 10, again with the winding section 220 winding on winding section 210, realize bandage 200 and holding head 10's rapid Assembly, improve work efficiency.

Furthermore, the surface of the winding section 210 attached to the clamping head 10 is provided with two protrusions 215 arranged at intervals, and when the winding section 210 is wound on the clamping head 10, the two protrusions 215 are respectively accommodated at two opposite sides of the elastic clamping cavity 14 in the clamping head 10 so as to fix the fingers in the elastic clamping cavity 14, thereby increasing the wearing stability of the clamping head 10. Specifically, two protrusions 215 are disposed on the first surface 211, and when the winding section 210 is wound on the clamping head 10, the two protrusions 215 are disposed on two sides of the elastic clamping cavity 14, respectively. When the measured finger is thin, the two protrusions 215 play a role in reducing the elastic clamping cavity 14, so that the finger is fixed in the elastic clamping cavity 14, the finger is prevented from deviating, and the phenomena of light fleeing and falling of the clamping head 10 are reduced. It should be understood that cross-talk is the light from the light emitter in the finger oximeter probe 100 that is reflected directly through the wall of the flexible clamping chamber 14 into the light receiver 20 without passing through the finger, and thus affects the result of blood oximetry measurement.

Preferably, the protrusion 215 is a hollow structure, so that when a finger is placed in the elastic clamping cavity 14, the protrusion 215 can avoid crushing the finger, and when the hollow protrusion 215 is deformed by being squeezed, the contact area between the finger and the elastic clamping cavity 14 can be increased, the friction force is increased, and the risk that the finger falls off when the clamping head 10 is worn on the finger is further reduced. It is understood that in other embodiments of the present application, the cavity of the protrusion 215 may be filled with an elastic filler such as cotton, so that the protrusion 215 has a solid structure and can also function as an elastic fixing finger. It should be noted that, a plurality of protrusions 215 may also be disposed on the first surface 211, and when the winding section 210 is wound around the clamping head 10, the plurality of protrusions 215 are symmetrically distributed on two sides of the elastic clamping cavity 14, so as to prevent fingers in the elastic clamping cavity 14 from deviating.

The fixing section 220 is connected with the winding section 210. Securing segment 220 includes a layer 223 of tensile material to protect band 200 and prevent band 200 from deforming with multiple uses, thereby increasing the life of band 200. Specifically, tensile material layer 223 is disposed on third surface 221, and tensile material layer 223 is made of a soft nylon material or other cloth material, so as to ensure the overall flexibility of band 200 to the maximum extent without increasing the hardness of band 200. It is understood that the tensile material layer is fixed on the third surface 221 by gluing or other means, which is not particularly limited in this embodiment. In other embodiments of the present embodiment, the tensile material layer 223 may also be disposed on the fourth surface 222, or formed in the middle of the fixing segment 220 by silicone molding or injection molding, so as to form a sandwich-like structure.

Further, the strap 200 includes a fastener for detachably fastening the fastening section 220 to the winding section 210.

Referring to fig. 5, in an embodiment of the present embodiment, the fixing element is a Hook and Loop fastener, the Hook and Loop fastener includes a Hook surface 231a and a Hook surface 231b, the Hook surface 231b and the Hook surface 231a are respectively disposed on the winding section 210 and the fixing section 220, that is, the winding section 210 and the fixing section 220 are combined by using the principle that the Hook and Loop fastener can be repeatedly attached and used. It should be noted that "respectively disposed" herein does not limit the order of the disposed positions, that is, the description that the hook surface 231b and the blank surface 231a are respectively disposed on the winding section 210 and the fixing section 220 does not limit the specific positions of the hook surface 231b and the blank surface 231a, that is, the hook surface 231b may be disposed on the winding section 210 or the fixing section 220, and the blank surface 231a is correspondingly disposed on the fixing section 220 or the winding section 210.

It is understood that the loop surface 231a of the hook and loop fastener is a fine and soft fiber surface, and when the loop surface 231a is provided on the band 200, the softness of the band 200 is not affected. The hook surface 231b is provided on the third surface 221, and the hook surface 231b is a hard and barbed surface, and in order to reduce the influence of the hook surface 231b on the flexibility of the band 200, the hook surface 231b includes a plurality of sub-hook surfaces 231c arranged at intervals. It should be noted that in other embodiments, the hair side may also include a plurality of sub-hair sides spaced apart to further increase the flexibility of the strap 200.

In the present embodiment, the roughened surface 231a is provided on the second surface 212. Specifically, the rough surface 231a partially covers the second surface 212, and the rough surface 231a is disposed at an end of the second surface 212 facing away from the fixing section 220. Further, the textured surface 231a includes a first end a1 and a second end (not shown) disposed opposite to each other. The first end a1 is located at the end of the textured surface 231a facing away from the fixed segment 220 and the second end is located at the end of the textured surface 231a facing the fixed segment 220. It should be noted that, in other embodiments, the rough surface 231a may also be completely laid on the second surface 212, and a user may adjust the area ratio of the rough surface 231a on the second surface 212 according to different requirements, which is not limited in this embodiment.

The hook surface 231b is disposed on the third surface 221. Specifically, the hook surface 231b is located at one end of the third surface 221 away from the winding section 210, so that no excess part of the fixing section 220 is not wound on the blood oxygen probe 100 after the hook surface 231b is attached to the hair surface 231a, thereby improving the smoothness during use. When the sub-hook surface 231c farthest from the winding section 210 is attached to the first end a1, the area enclosed by the binding band 200 is the largest, and the size of the elastic clamping cavity 14 in the clamping head 10 is the largest, that is, the elastic clamping cavity 14 can clamp the thickest finger. When the sub-hook surface 231c nearest to the winding section 210 is engaged with the second end, the area enclosed by the band 200 is the smallest, and the size of the elastic clamping cavity 14 of the clamping head 10 is the smallest, that is, the elastic clamping cavity 14 can clamp the finest finger. In other embodiments, the hook surface 231b may also be disposed at an end of the third surface 221 facing the winding section 210, and a receiving ring is additionally disposed on the second surface 212, so that after the hook surface 231b is attached to the hair surface 231a, a portion of the fixing section 220 that is not wound on the blood oxygen probe 100 is received by the receiving ring, which may also improve the smoothness during use.

It is understood that, in other embodiments, the hook surface 231b may also be disposed on the second surface 212, and the rough surface 231a is correspondingly disposed on the third surface 221, and the detachable combination between the winding section 210 and the fixing section 220 can also be achieved, and other specific structures of the binding band 200 are similar to those of the above embodiments, and will not be described herein again.

Referring to fig. 6, in a second embodiment of the present embodiment, the difference from the first embodiment is that the fixing member includes a fixing ring 232, the fixing ring 232 is disposed on the surface of the winding section 210 or the fixing section 220, the fixing ring 232 is used for the fixing section 220 or the winding section 210 to pass through, and the height of the inner ring in the fixing ring 232 is less than or equal to the thickness of the fixing section 220 or the winding section 210. The fixing ring 232 and the binding band 200 are integrally formed, and the friction force between the silicone rubber and the fixing ring 232 is large, so that when the fixing section 220 or the winding section 210 penetrates through the fixing ring 232, the fixing section 220 or the winding section 210 is tightened in the fixing ring 232 by the friction force generated between the fixing section 220 and the winding section 210, namely, the principle that the winding section 210 and the fixing section 220 are locked by the friction force is combined. Note that the height of the inner ring in the fixing ring 232 refers to the distance between the inner wall of the inner ring of the fixing ring 232 disposed opposite to the band 200 and the band 200.

In this embodiment, the fixing ring 232 is disposed on the second surface 212 of the winding section 210, and when the fixing section 220 passes through the fixing ring 232, a friction force is generated between the fixing ring 232 and the fixing ring 232 to lock the fixing section 220 in the fixing ring 232. It should be noted that, in other embodiments, the fixing ring 232 may be multiple, the fixing rings 232 are disposed on the second surface 212 at intervals, and the fixing section 220 sequentially passes through the fixing rings 232 to increase friction force and improve the bonding force between the fixing section 220 and the winding section 210. It can be understood that, as long as the width of one fixing ring 232 is smaller than the width of the fixing section 220, the friction locking structure between the fixing section 220 and the winding section 210 can be realized, and the rest fixing rings 232 can accommodate the redundant parts of the fixing section 220, so as to improve the neatness of the binding band in the using process.

Referring to fig. 7, in the third embodiment of the present embodiment, the difference from the two embodiments is that the fixing member includes a buckle 233a and a plurality of first through holes 233b, the buckle 233a and the plurality of first through holes 233b are respectively disposed on the winding section 210 and the fixing section 220, and the buckle 233a can be clamped with the first through holes 233 b. The buckle 233a and the binding band 200 are integrally formed, the buckle 233a includes a clamping end 233c facing away from the binding band 200, and the clamping end 233c is larger than the first through hole 233b, so that after the buckle 233a passes through the first through hole 233b, the clamping end 215b cannot easily pass through the first through hole 233b to cause the fixing section 220 to fall off from the winding section 210, thereby ensuring the combination stability between the fixing section 220 and the winding section 210. It will be appreciated that in other embodiments, the clasp could be fitted to the strap rather than being integrally formed with the strap.

In this embodiment, the latch 233a is disposed on the second surface 212, and the plurality of first through holes 233b are disposed on the fixing section 220. When the buckle 233a passes through the first through hole 233b closest to the winding section 211, the area enclosed by the band 200 is the smallest, and at this time, the size of the elastic clamping cavity 14 in the clamping head 10 is the smallest, that is, the elastic clamping cavity 14 can clamp the finest finger; when the snap 233a passes through the first through hole 233b farthest from the winding section 211, the area surrounded by the band 200 is smallest, and the size of the elastic grip cavity 14 in the grip head 10 is largest, that is, the state where the elastic grip cavity 14 can grip the thickest finger.

Further, the fixing member further includes a receiving ring 233d, and the receiving ring 233d is located between the catch 233a and the plurality of first through holes 233b to receive the fixing section. After the first through hole 233b of the fixing section 220 is fastened to the buckle 233a, the remaining portion of the fixing section 220 passes through the receiving ring 233d so that the fixing section 220 is entirely wound around the winding section 210, thereby improving the smoothness of the band 200 during use. It can be understood that when the height of the inner ring of the receiving ring 233d is less than the thickness of the fixing segment 220, when the fixing segment 220 passes through the receiving ring 233d, friction is generated between the two, increasing the coupling force between the fixing segment 220 and the winding segment 210.

After the light emitter is placed in the first mounting groove 111, the light emitter is fixed in the first mounting groove 111 in a glue pouring manner, and compared with the case that the first wire 40 and the second wire 50 are wired from the upper side or both sides of the first mounting groove 111, the first wire 40 and the second wire 50 are wired from the first mounting groove 111, so that the width and the thickness of the first clamping body 11 are effectively reduced. It should be noted that, when the size of the first mounting groove 111 is just the same as the size of the light emitter, and the light emitter is placed in the first mounting groove 111, the light emitter does not need to be fixed by glue filling, and at this time, the first wire 40 and the second wire may be routed through the first mounting groove 111, or may be routed through the top or both sides of the first mounting groove 111.

Specifically, the surface of each light barrier 30 attached to the clamping head 10 is an arc surface, so that when two light barriers 30 are assembled on the bending section 13, the two light barriers 30 are in a folded state, and the light shielding effect of the light barriers 30 on the elastic clamping cavity 14 is improved. Further, the blood oxygen probe 100 further comprises a connecting sheet 31 for connecting the two light blocking sheets 30, the connecting sheet 31 is assembled on one side of the bending section 13 departing from the opening of the elastic clamping cavity 14, and the connecting sheet 31 and the two light blocking sheets 30 are integrally formed by elastic materials. When the light blocking sheet 30 and the connecting sheet 31 are not assembled on the bending section 13, the two light blocking sheets 30 tend to be folded inwards, the radian of the two light blocking sheets 30 is larger than that of the two light blocking sheets assembled on the bending section 13, when the light blocking sheets are assembled on the bending section 13, the radians of the two light blocking sheets 30 can be reduced to be tightly attached to the surface of the bending section 13, when the light blocking sheets are seen from top to bottom from the view angle of fig. 1, the light blocking sheets are C-shaped, when the blood oxygen probe 100 is used for measurement, the two light blocking sheets 30 are completely attached to the clamping head 10, and the light leakage risk is reduced.

Referring to fig. 18, in the present application, the blood oxygen probe 100 further includes a cable fixing strap 300, and the cable fixing strap 300 fixes the wires of the blood oxygen probe 100 to the wrist. Specifically, the cable fixing band 300 fixes the ends of the first and second wires 50 and 60 away from the gripping head 10 at a wrist (wrist or ankle). It can be understood that, during the blood oxygen measurement, the ends of the first and second wires 50 and 60 extending out of the holding head 10 are in an unstable state, and are easily torn to cause the holding head 10 to fall off the fingers, and the cable fixing band 300 fixes the unstable portions of the first and second wires 50 and 60 on the wrist to reduce the risk of falling off the holding head 10. It should be noted that, when the blood oxygen measuring probe 100 is not performing blood oxygen measurement, the cable fixing strap 200 can also store the portions of the first conducting wire 50 and the second conducting wire 60 extending out of the holder 10, so as to improve the smoothness.

The cable fixing band 300 is made of silica gel, so that the cable fixing band can be repeatedly used for many times and is beneficial to improving the comfort level in the use process. Specifically, the cable retention strap 300 includes a first section 310, a second section 320 connected to the first section 310, and a binder. The first section 310 is wound around the wrist, and a fixing portion is disposed on a surface of the first section 310 facing away from the wrist, and the fixing portion fixes the first lead 50 and the second lead 60. The second section 320 is wrapped around the first end 310 and a coupling removably attaches the second section 320 to the first section 310. The fifth surface 312 is provided with fixing portions 3121 and third coupling members disposed at intervals.

In this embodiment, the fixing portion is a fixing ring 311, and the fixing ring 311 and the cable fixing band 300 are integrally formed to increase the stability between the fixing ring 311 and the cable fixing band 300. Specifically, the opening direction of the fixing ring 311 is perpendicular to the length direction of the cable fixing band 300, and the width of the fixing ring 311 is not greater than the sum of the widths of the first conducting wire 50 and the second conducting wire 60, so that the first conducting wire 50 and the second conducting wire 60 can be restrained after passing through the fixing ring 311. In other embodiments, the fixing portion 3121 may also be configured to fix a wire, which is not specifically limited in this application.

The combining component comprises a fixing buckle 331 and a plurality of second through holes 332, wherein the fixing buckle 331 and the plurality of second through holes 332 are respectively arranged on the first section 310 and the second section 320, so that the first section 310 and the second section 320 are combined in a hole buckle-like manner and wound on the wrist. In one embodiment of the present invention, the fixing button 331 and the fixing ring 311 are disposed on the same surface. Specifically, the fixing buckle 331 is disposed on a side of the fixing ring 311 away from the second section 320, the fixing buckle 331 and the first section 310 are integrally formed, and the plurality of second through holes 332 are disposed on the second section 320 at intervals. The fixing buckle 331 includes a fixing end facing away from the cable fixing band 300, and the size of the fixing end is larger than that of the second through hole 332, so that after the fixing buckle 331 passes through the second through hole 332, the fixing end cannot easily pass through the second through hole 332, and the cable fixing band 300 falls off from the wrist. It can be understood that the fixing button 331 passes through the second through hole 332 at different positions to make the area surrounded by the cable fixing band 300 have different sizes, so that the cable fixing band 300 can be worn on the wrist with different thickness. When the fixing buckle 331 passes through the second through hole 332 closest to the first segment 310, the area surrounded by the cable fixing band 300 is the smallest, and at this time, the thinnest wrist state that the cable fixing band 300 can be worn is obtained; when the fixing buckle 332 passes through the second through hole 332 farthest from the first segment 310, the area surrounded by the cable fixing band 300 is the smallest, and this is the thinnest wrist state that the cable fixing band 300 can be worn.

Further, the joint further comprises a receiving ring 333 positioned on a side of the fixing ring 311 away from the fixing buckle 331. After the fixing buckle 331 is fastened to the second through hole 332, the remaining portion of the second section 320 passes through the receiving ring 333 and is wound around the wrist, so as to improve the cleanliness of the cable fixing band 300 during use.

It should be noted that the coupling member of the present embodiment may also be another structure that allows the first section 310 and the second section 320 to be detachably coupled, such as a hook and loop fastener or a friction coupling structure as used in the above-mentioned binding band 200, and since the structure of the cable fixing band 300 is substantially the same in other embodiments, it will not be described herein too much.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
