Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a reflection type blood oxygen simulator according to an embodiment of the utility model, and fig. 2 is a schematic exploded perspective diagram of the reflection type blood oxygen simulator according to the embodiment shown in fig. 1. As shown in fig. 1 and 2, the reflective blood oxygen simulator 100 may be applied to a reflective blood oxygen device 200 (shown in fig. 6). In particular, the reflex blood oxygen simulator 100 may include a connector 10 and a finger simulation structure 20 mounted on the connector 10. Wherein, the connecting piece 10 can be in a strip shape and comprises: a first connection part 11 having a first connection end and a second connection end opposite to the first connection end, wherein a holding structure is provided on the first connection part 11; and a second connecting portion 12 extending along the second connecting end away from the first connecting end. The reflection type blood oxygen simulator 100 may further include: the finger simulation structure 20, and the holding structure and the finger simulation structure 20 are disposed at both sides of the connection member 10 opposite to each other. Further, the second connecting portion 12 is configured to enable the connector 10 to be looped over the reflex blood oxygen apparatus 200 by fixing the distal end or a portion adjacent to the distal end thereof by the holding structure while connecting the finger simulating structure 20 to the reflex blood oxygen apparatus 200.

In some embodiments, the first connection end of the first connection part 11 is provided with a first through hole 110. Further, the first connection portion 11 is further provided with a second through hole 112 at a second connection end distant from the first through hole 110. The holding structure of the first connection part 11 includes a first through hole 110 provided at the first connection end and a second through hole 112 provided at the second connection end. Wherein the second connection part 12 is configured to be able to pass its distal end through the first through hole 110 and the second through hole 112 in order to fix the second connection part 12 by the first through hole 110 and the second through hole 112. Thus, the reflective blood oxygen simulator 100 of the present utility model is configured such that the first connection part 11 is provided with a holding structure including the first through hole 110 and the second through hole 112, thereby enabling the connection member 10 to be looped over the reflective blood oxygen device 200 while the finger simulation structure 20 is connected to the reflective blood oxygen device 200. Therefore, the structural design of the connecting piece of the reflective blood oxygen simulator can effectively improve the fitting precision between the reflective blood oxygen simulator and the reflective blood oxygen equipment, and further improve the data precision and the data consistency of the reflective blood oxygen simulator.

It should be noted that, in some embodiments, the retaining structure of the first connection portion 11 may also include a through hole, for example, the first through hole or the second through hole. At this time, the aperture of the through hole may be designed according to the width dimension of the second connection portion 12 so that the end of the second connection portion 12 may be fixed in the through hole. Specifically, the aperture of the through hole may be smaller than the width dimension of the second connection portion 12, as long as the second connection portion 12 can be made to pass through the through hole on the holding structure and be fixed in the through hole. Thus, the provision of a through hole in the holding structure also enables the attachment member 10 to be looped over the reflex blood oxygen apparatus 200.

In some embodiments, the connector 10 is an elastic structure, for example, it may be an elastic, stretchable strap-securing structure. In a specific use process, when the reflective blood oxygen simulator 100 needs to be fixedly connected to the reflective blood oxygen device 200, since the connecting piece 10 has an elastic and stretchable binding band fixing structure, the tail end of the second connecting portion 12 can sequentially pass through the first through hole 110 and the second through hole 112 on the first connecting portion 11, so that the reflective blood oxygen simulator 100 is quickly and fixedly connected to the reflective blood oxygen device 200, and the adapting time of the reflective blood oxygen simulator 100 and the reflective blood oxygen device 200 is effectively reduced. It will be appreciated that the second connecting portion 12 sequentially passes through the first through hole 110 and the second through hole 112, and the two through holes can provide the first friction force along the extending direction corresponding to the through holes for the second connecting portion 12, so that the end of the second connecting portion 12 can be firmly limited in the two through holes.

In some embodiments, the length of the second connection portion 12 is long enough, so that the length between the end of the second connection portion 12 and the first connection portion 11 can be adjusted according to the instrument requirement of the reflective blood oxygen device 200 until the reflective blood oxygen simulator is matched with the reflective blood oxygen device 200 to be compatible, so that the reflective blood oxygen simulator can be compatible with different reflective blood oxygen devices 200, and the compatibility is improved. At the same time, the disadvantage of the reflective blood oxygen simulation device 200 of the related art that it is generally only capable of supporting a fixed size can be avoided.

Referring to fig. 3 and 4 in combination with fig. 1 and 2, fig. 3 is a schematic structural view illustrating another view angle of the reflective blood oxygen simulator in the embodiment of fig. 1, and fig. 4 is a schematic sectional view illustrating a first connection portion of the reflective blood oxygen simulator in the embodiment of fig. 1. As shown in fig. 3 and 4, in some embodiments, the connector 10 further includes a groove 114. Specifically, the groove 114 is disposed on the first connecting portion 11 and opposite to the receiving cavity 101 on two sides of the connecting member 10, wherein the second connecting portion 12 is configured to sequentially pass through the first through hole 110, the groove 114 and the second through hole 112.

In some embodiments, the extending direction of the first through hole 110 is disposed along the thickness direction A1 of the first connection portion 11. The second through hole 112 may include a first end 112a and a second end 112b extending along the first end 112 a. The first end 112a is disposed toward the second connecting portion 12 and extends along the length direction A2 of the first connecting portion 11, the second end 112b is connected to the groove 114, and the groove 114 extends along the second end 112b. In some embodiments, the extending direction of the first through hole 110 and the extending direction of the first end 112a are disposed substantially perpendicular to each other.

In some embodiments, as shown in fig. 4, the first through hole 110 may have a rectangular cross-sectional shape. The cross-sectional shape of the second through hole 112 may be arc-shaped. That is, the second through hole 112 may be an arc hole. Further, the extending direction of the second end 112b may form an angle of 90-180 degrees, preferably 90-120 degrees with the extending direction of the first end 112a, so as to form the arc-shaped second through hole 112.

In the structural design of the reflective blood oxygen simulator in the present utility model, the first through hole 110 and the second through hole 112 provided in the first connecting portion 11 have different extending directions and different structural designs, and the connecting member 10 has an elastic and stretchable strap fixing structure, so that the structural design not only enables the end of the second connecting portion 12 to pass through the first through hole 110 and the second through hole 112 in sequence to firmly loop the connecting member 10 on the reflective blood oxygen device 200, thereby enabling the reflective blood oxygen simulator 100 to be more attached to the reflective blood oxygen device 200, but also enables the finger simulation structure 20 to be fixedly connected on the reflective blood oxygen device 200. Thus, the reflection type blood oxygen simulator 100 of the present utility model can effectively improve the fitting accuracy between the reflection type blood oxygen simulator 100 and the reflection type blood oxygen equipment 200, and further improve the data accuracy and the data consistency of the reflection type blood oxygen simulator 100.

In some embodiments, the apertures of the first through hole 110 and the second through hole 112 on the first connection portion 11 are adapted to the width of the second connection portion 12. That is, the specific size is not limited as long as the apertures of the two through holes on the first connecting portion 11 satisfy the requirement that the distal end of the second connecting portion 12 can pass through the two through holes and reach the condition that the connector 10 is annularly provided on the reflex blood oxygen apparatus 200. Alternatively, the apertures of the first and second through holes 110 and 112 may be smaller than the width of the second connection part 12, so that the second connection part 12 may be firmly fixed in the two through holes.

With continued reference to fig. 1-4, in some embodiments, the recess 114 is curved in a direction away from the second end 112b, with a gradual increase in the degree of curvature and a gradual decrease in the degree of curvature. That is, the portion of the groove 114 near the second end 112b is curved to a greater extent than the portion of the groove 114 remote from the second end 112b. For convenience of description, a portion of the groove 114 near the second end 112b is referred to as a first sub-groove 114a, and a portion of the groove 114 remote from the second end 112b is referred to as a second sub-groove 114b. The second sub-groove 114b is less curved than the first sub-groove 114 a.

In some embodiments, the portion of the bottom of the groove 114 distal from the second end 112b is in a first arc, i.e.: the bottom of the second sub-groove 114b has a first arc shape. Further, the degree of curvature of the first arc gradually decreases in a direction in which the second sub-groove 114b is away from the second end 112b.

In some embodiments, the first connection portion 11 further includes an arcuate portion between the recess 114 and the first through hole 112, namely: an arc shape between the second sub-groove 114b and the first through-hole 110. For convenience of description, the arc-shaped portion between the second sub-groove 114b and the first through-hole 110 may also be referred to as a bent portion. In some embodiments, the degree of curvature of the curved portion is greater than the degree of curvature of the first arc.

In the structural design of the first connecting portion 11 in the embodiment of the present utility model, the grooves 114 are configured into shapes with different bending degrees, and the bending degree of the bending portion is greater than that of the first arc (i.e. the arc shape of the bottom of the second sub-groove 114 b), so that the whole first connecting portion 11 is designed with a certain radian. The present utility model adopts such a structure that the first connection portion 11 and the second connection portion 12 can be better fitted with the reflex blood oxygen apparatus 200. Namely: when the connecting piece 10 is annularly arranged on the reflective blood oxygen device 200, one side of the first connecting part 11, which deviates from the second through hole 112, is attached to the reflective blood oxygen device 200, therefore, the first connecting part 11 with a certain radian design can be better attached to the reflective blood oxygen device 200, and when the tail end of the second connecting part 12 passes through the two through holes and the groove 114 on the first connecting part 11, the connecting piece 10 can be integrally annularly arranged on the reflective blood oxygen device 200, so that the attaching precision between the two can be effectively improved, and the data precision and the data consistency of the reflective blood oxygen simulator 100 can be simultaneously improved.

In some embodiments, the recess 114 has two opposing sidewalls 1141. Wherein, both side walls 1141 are configured to limit the second connecting portion 12. Specifically, the second connecting portion 12 sequentially passes through the first through hole 110, the groove 114 and the second through hole 112, not only the two through holes can provide the first friction force along the extending direction corresponding to the through holes for the second connecting portion 12, but also the groove 114 can provide the second friction force for the second connecting portion 12 (wherein the direction of the second friction force is approximately perpendicular to the extending direction of the two side walls 1141 of the groove 114), so that the end of the second connecting portion 12 is more firmly limited in the two through holes of the first connecting portion 11.

In a specific use process, when the reflective blood oxygen simulator 100 needs to be fixedly connected to the reflective blood oxygen device 200, the end of the second connecting portion 12 can be sequentially connected to the reflective blood oxygen device 200 through the first through hole 110 and the second through hole 112 on the first connecting portion 11, and the connecting member 10 can be annularly arranged on the reflective blood oxygen device 200, or the end of the second connecting portion 12 can be sequentially connected to the reflective blood oxygen device 200 through the first through hole 110, the groove 114 and the second through hole 112 on the first connecting portion 11, and both modes can effectively reduce the adapting time of the reflective blood oxygen simulator 100 and the reflective blood oxygen device 200. That is, in the structural design of the reflective blood oxygen simulator provided in the embodiment of the present utility model, the first through hole 110 and the second through hole 112 cooperate together to achieve the effect of locking the second connecting portion 12. Further, the groove 114 is further provided on the first connecting portion 11, so that the fitting accuracy between the reflective blood oxygen simulator 100 and the reflective blood oxygen device 200 can be further improved, and the locking effect can be further improved. Accordingly, in some embodiments, the first through hole 110 and the second through hole 112 on the first connection part 11 may be referred to as a secondary locking structure, and accordingly, the first through hole 110 may be referred to as a first locking hole, and the second through hole 112 may be referred to as a second locking hole. Further, the groove 114 on the first connecting portion 11 may also be referred to as a locking groove. At this time, the locking structure formed by the first through hole 110, the groove 114, and the second through hole 112 on the first connection portion 11 may also be referred to as a secondary locking structure.

With continued reference to fig. 2 and 4, in some embodiments, as shown in fig. 2 and 4, the connector 10 is further provided with a receiving cavity 101 and a retaining structure disposed on opposite sides of the connector 10 and configured to receive the finger simulating structure 20. Specifically, the receiving cavity 101 may be disposed between the first through hole 110 and the second through hole 112. It is understood that the placement of the accommodating cavity 101 may be set according to the reflective blood oxygen device 200 adapted to the reflective blood oxygen simulator 100, for example, the accommodating cavity 101 may be disposed on the first connecting portion 11, or may be disposed on the second connecting portion 12, or may be disposed at a connection portion between the first connecting portion 11 and the second connecting portion 12. The present utility model is not particularly limited as long as the finger simulation structure 20 can be satisfactorily fixedly mounted on the connector 10. For convenience of description, the present utility model is described with the housing cavity 101 disposed on the first connecting portion 11.

Specifically, as shown in fig. 4, the recess 114 and the receiving cavity 101 are provided on both sides of the connection member 10 opposite to each other. For example, the receiving cavity 101 is disposed on a side of the connector 10 that is engaged with the reflective blood oxygenation device 200, and the recess 114 is disposed on a side of the connector that is opposite from the connector 10 that is engaged with the reflective blood oxygenation device 200.

Referring to fig. 5 in combination with fig. 2, fig. 5 shows a schematic structural diagram of a housing of the finger simulation structure in the embodiment shown in fig. 2. In some embodiments, the finger simulation structure 20, also referred to as a finger simulator or a reflective blood oxygenation finger simulation structure 20, is fixedly connected to the reflective blood oxygenation device 200 by a connector 10 to calibrate and verify the reflective blood oxygenation device 200.

Specifically, as shown in fig. 2 and 5, the finger simulation structure 20 may include: a housing 21, a light emitting member 22, a light receiving member 23, and a light shielding member 24. Wherein, casing 21 includes major surface 25, and casing 21 has seted up first accommodation groove 201 and has set up the second accommodation groove with first accommodation groove 201 interval in the side that deviates from major surface 25. A light emitting element 22 which is accommodated in the first accommodation groove 201 and whose light emitting side is exposed at the main surface 25 of the housing 21; the photosensitive member 23 is accommodated in the second accommodation groove, and the photosensitive side thereof is exposed at the main surface 25 of the housing 21; and a light shielding member 24 provided on the main surface 25 of the housing 21 and located between the light emitting side of the light emitting member 22 and the light receiving side of the light receiving member 23, and the light shielding member 24 protrudes from the main surface 25 of the housing 21.

In some embodiments, as shown in fig. 5, the housing 21 includes a bottom plate 211, and a first side plate 212, a second side plate 213, a third side plate 214, and a fourth side plate 215 connected to the bottom plate 211 and connected end to end, respectively. Wherein, the first end of the first side plate 212 is connected to the end of the fourth side plate 215. The bottom plate 211 and the first side plate 212, the second side plate 213, the third side plate 214 and the fourth side plate 215 connected end to end enclose together to form a containing groove. The accommodating groove comprises a first accommodating groove 201 and a second accommodating groove which is arranged at intervals with the first accommodating groove 201. The first accommodation groove 201 is for accommodating the light emitting member 22, and the second accommodation groove is for accommodating the photosensitive member 23.

In some embodiments, the glowing member 22 is a glowing source, such as an LED lamp. The number of the LED lamps can be set according to specific design requirements. The photosensitive member 23 is a light receiver, for example, a photodiode. Specifically, the photosensitive member 23 includes a first photosensitive member 23a and a second photosensitive member 23b, and the first photosensitive member 23a is a photodiode that receives red light, and the second photosensitive member 23b is a photodiode that receives infrared light.

In some embodiments, the second receiving groove may include a second sub-receiving groove 203 in which the first sub-receiving groove 202 is juxtaposed with the first sub-receiving groove 202. Wherein, the first sub-accommodating groove 202 is used for accommodating the first photosensitive member 23a. The second sub-receiving groove 203 is for receiving the second photosensitive member 23b.

In some embodiments, the end of the housing 21 away from the light emitting member 22 is further provided with a wire slot 204 to accommodate connection wires to the light emitting member 22, the first light sensing member 23a, and the second light sensing member 23b. The connecting wires may include connecting wires welded to the light emitting member 22, the first light receiving member 23a receiving red light, and the second light receiving member 23b receiving infrared light, so as to prevent the connecting wires from being scattered and thus from being accidentally torn during the assembly process.

In this finger simulation structure 20, by integrally designing the light emitting member 22, the first photosensitive member 23a, and the second photosensitive member 23b in the accommodating groove of the housing 21, both are located on the side of the housing 21 facing away from the main surface 25 of the housing 21. That is, the light emitting member 22 and the light sensing member 23 are integrated in the same structural component, which belongs to an integrated design, so that the total volume of the finger simulation structure 20 is miniaturized, and the finger simulation structure 20 can be adapted to various types of reflective blood oxygen devices 200, and meanwhile, the accuracy of instrument detection can be effectively improved.

In some embodiments, the light shielding member 24 is a strip-shaped flexible structural member, for example, the flexible structural member is made of a black non-reflective, opaque and soft material, so that the light shielding member 24 mounted on the main surface 25 of the housing 21 can simulate the state that a human finger is tightly attached when pressed against the sensor surface of the reflective blood oxygen device 200, thereby isolating the interference of the ambient light with the signal light emitted from the finger simulation structure 20. In a specific use process, when the finger simulation structure 20 is fixedly connected to the reflective blood oxygen device 200 through the connecting piece 10, the light shielding piece 24 can simulate the sealing light shielding effect when a human finger is tightly attached to the sensor position of the reflective blood oxygen device 200, and the following light shielding effect is achieved: on the one hand, the light shielding member 24 can completely shield the ambient light, thereby preventing it from interfering with the processed signal light emitted from the finger-simulating structure 20; on the other hand, the light shielding member 24 can completely shield the light emitted from the reflective blood oxygenation device 200, thereby preventing it from interfering with the processed signal light emitted from the finger-simulating structure 20. Therefore, the interference of light in the data acquisition process can be effectively reduced, and the data error is reduced, so that the data accuracy is effectively improved.

It will be appreciated that the distance between the light emitting member 22 and the light receiving member 23 on the main surface 25 of the housing 21 of the finger simulation structure 20 can be adjusted by the reflective blood oxygen device adapted thereto, so long as the device requirements of the reflective blood oxygen device 200 adapted thereto can be satisfied.

Accordingly, the shape of the accommodating cavity 101 provided on the connector 10 is adapted to the shape of the finger simulating structure 20, so as to accommodate the finger simulating structure 20 therein. For example, the receiving cavity 101 may have a substantially rectangular shape.
