Abstract

An electro-optical sensor probe (12) for non-invasive monitoring of blood oxygenation levels is engaged with the blood-perfused tissue (23) of a patient by a device (10) having a woven tube (20) that receives the probe (12) and selectively engages the probe (12) and the tissue (23). The tube (20) includes a cuff (27) formed integrally therewith for carrying the probe (12). Once the probe (12) located within cuff (27) is placed into engagement with tissue (23), tube (20) is extended over the tissue (23).

Claims

1. A device comprising:

sensor probe means for engagement with a test surface; and

tube means for receiving said probe means and selectively engaging said probe means and said test surface, said tube means having an end and including a cuff means for carrying said probe means, said cuff means formed integrally with said tube means by rolling said end of said tube means.

2. A device as set forth in claim 1, wherein said probe means is non-invasive and electro-optical said probe means engages blood-perfused tissue, and said tube means is substantially cylindrically shaped and made of woven material.

3. A device as set forth in claim 1, wherein said probe means is non-invasive and electro-optical, engages blood-perfused tissue, and said probe means includes a housing carrying a light source and a photosensor, said housing including interlock means for securing said probe means to said cuff means.

4. A device comprising:

means for engagement with blood-perfused tissue of a patient including a non-invasive, electro-optical sensor probe and a probe housing having separate wells carrying a light source and a photosensor; and

tube means for receiving said probe and selectively engaging said probe and said tissue, said tube means having an end and including a cuff means for carrying said probe, said cuff means formed integrally with said tube means by rolling said end of said tube means, said wells securing said probe to said cuff means by interference fit.

5. A method for engaging a sensor probe with the tissue of a patient including the steps of:

engaging the tissue with the probe located within a cuff formed in a tube having an end by rolling said end of said tube; and

,

extending said tube over the tissue.

6. A method for engaging a non-invasive, electro-optical sensor probe with the blood-perfused tissue of a patient including the steps of:

engaging the tissue with the probe located within a cuff formed in a tube;

said step of engaging including the step of repeatedly engaging the tissue at multiple tissue sites to identify a preferred engagement location, and finally engaging the tissue with the probe at said preferred engagement location; and

,

extending said tube over the tissue.

7. A method for engaging a sensor probe with the tissue of a patient including the steps of:

forming a cuff in a tube having an end by rolling said end of said tube;

locating the probe within the cuff;

engaging the tissue with the probe within the cuff; and

,

extending said tube over the tissue.

8. A method as set forth in claim 7, wherein the probe is non-invasive and electro-optical, the probe engages blood-perfused tissue, and said step of engaging includes the step of repeatedly engaging the tissue at multiple tissue sites to identify a preferred engagement location, and finally engaging the tissue with the probe at said preferred engagement location.
