Abstract

A binding strap used in connection with a SpO2 sensor comprises two clamping portions each of which is provided with an access opening for passing the light emitting portion or light receiving portion of the SpO2 sensor and a holding recess for holding corresponding light emitting portion or light receiving portion, wherein said access openings are designed to allow corresponding light emitting portion or light receiving portion to pass only when said access openings are undergoing a certain amount of deformation. The binding strap of the present invention is advantageous in that the light emitting portion and the light receiving portion of the SpO2 sensor might be tightly secured to the binding strap, and the lost of the binding strap when not use is ensured to be hard.

Claims

1. A binding strap used in connection with a SpO2 sensor, which comprises:

a main body consisting of a first clamping portion, a second clamping portion and a connection portion connecting said first clamping portion and said second clamping portion;

a wrapping body integrally extended from said first clamping portion of said main body;

a first access opening penetratingly formed in said first clamping portion and allowing a light emitting portion of said SpO2 sensor to selectively pass therethrough;

a first holding recess concavely formed in an inner side of said first clamping portion facing said second clamping portion, and adapted to hold said light emitting portion having passed through said first access opening;

a second access opening penetratingly formed in said second clamping portion and allowing a light receiving portion of said SpO2 sensor to selectively pass therethrough; and

a second holding recess concavely formed in an inner side of said second clamping portion facing said first clamping portion, and adapted to hold said light receiving portion having passed through said second access opening;

wherein each of said first and second access openings is designed to allow said light emitting portion or said light receiving portion to pass therethrough only when said access opening is undergoing a certain amount of deformation.

2. The binding strap according to claim 1, wherein said binding strap is made of elastically deformable material.

3. The binding strap according to claim 2, wherein said elastically deformable material is silica gel.

4. The binding strap according to claim 1, wherein each of said light emitting portion and said light receiving portion is a plate member in an elliptical shape, said first access opening having an elliptical profile with a major axis slightly shorter than a minor axis of said light emitting portion, said second access opening having an elliptical profile with a major axis slightly shorter than a minor axis of said light receiving portion.

5. The binding strap according to claim 1, wherein each of said light emitting portion and said light receiving portion is a plate member in an elliptical shape, said first access opening having a circular profile with a diameter slightly shorter than a minor axis of said light emitting portion, said second access opening having a circular profile with a diameter slightly shorter than a minor axis of said light receiving portion.

6. The binding strap according to claim 1, wherein each of said light emitting portion and said light receiving portion is a plate member in an elliptical shape, and said first holding recess and said second holding recess are respectively formed in an elliptical shape with a slightly smaller dimension than that of corresponding light emitting portion or light receiving portion so as to tightly hold said light emitting portion or said light receiving portion therein.

7. The binding strap according to claim 6, wherein said first access opening and said second access opening respectively have an elliptical profile whose major axis is slightly shorter than a minor axis of corresponding light emitting portion or light receiving portion, and the minor axis of said first access opening and the major axis of said first holding recess lie in a common line, and the minor axis of said second access opening and the major axis of said second holding recess lie in another common line.

8. The binding strap according to claim 1, wherein said first clamping portion is provided with a first projection and said second clamping portion is provided with a second projection, both projections protruding in a width direction of said binding strap, and said first and second access openings are respectively formed in said first and second projections.

9. The binding strap according to claim 1, wherein

said first clamping portion is further provided with a first inner cable clamping groove on said inner side thereof, which communicates said first access opening with said first holding recess, so as to clamp the cable or cable sheath of said light emitting portion therein from the inner side of said first clamping portion;

and

said second clamping portion is further provided with a second inner cable clamping groove on said inner side thereof, which communicates said second access opening with said second holding recess, so as to clamp the cable or cable sheath of said light receiving portion therein from the inner side of said second clamping portion.

10. The binding strap according to claim 1, wherein

said first clamping portion is further provided with a first outer cable clamping groove on an outer side of said first clamping portion facing away from said second clamping portion, which is communicated with said first access opening and extends to an edge of said first clamping portion, so as to clamp the cable or cable sheath of said light emitting portion therein from the outer side of said first clamping portion;

and

said second clamping portion is further provided with a second inner cable clamping groove on an outer side of said second clamping portion facing away from said first clamping portion, which is communicated with said second access opening and extends to an edge of said second clamping portion, so as to clamp the cable or cable sheath of said light receiving portion therein from the outer side of said second clamping portion.

11. The binding strap according to claim 1, wherein said main body is in a substantially U-shape.

12. The binding strap according to claim 1, wherein said second clamping portion is further provided with a first inserting slot on an outer side of said second clamping portion facing away from said first clamping portion, which is positioned on a winding track of said wrapping body and is dimensioned so as to enable said wrapping body to pass through it and to be clamped therein.

13. The binding strap according to claim 12, wherein said first inserting slot is a cutout defined by a bottom wall, two side walls, and a beam portion bridging across said two side walls, in which a distance between said two side walls is substantially equal to a width of said wrapping body, and a spacing of bottom surface of said beam portion from the bottom wall of said first inserting slot is slightly smaller than a thickness of said wrapping body so as to clamp said wrapping body therein.

14. The binding strap according to claim 12, wherein said connection portion is provided with a second inserting slot on an outer side thereof, which is positioned on the winding track of said wrapping body and is dimensioned so as to enable said wrapping body to pass through it and to be clamped therein.
