Abstract

A non-invasive medical probe includes a suction cup adapted to be secured by vacuum to a patient'"'"'s skin and supporting an electrode, a source of vacuum, and a resilient walled tube structure connecting the source of vacuum to the suction cup, the source of vacuum including a resilient bellows operative when fully compressed and then released to apply a predetermined low level of vacuum to the suction cup and an arrangement connected with the bellows for enabling the bellows to be further extended manually in order to increase the vacuum applied to the suction cup to a higher level, the arrangement including a thumb ring secured to a closed end of the bellows and a finger abutment at an opposite end of the bellows.

Claims

1. A non-invasive medical probe comprising:

a suction cup adapted to be secured by vacuum to a patient'"'"'s skin and supporting an electrode,

a source of vacuum, and

a resilient walled tube structure connecting the source of vacuum to the suction cup,

the source of vacuum comprising a resilient bellows operative when fully compressed and then released to apply a predetermined low level of vacuum to the suction cup and an arrangement connected with the bellows for enabling the bellows to be further extended manually in order to increase the vacuum applied to the suction cup to a higher level.

2. A non-invasive medical probe as claimed in claim 1, wherein the arrangement for enabling the bellows to be further extended manually comprises a thumb ring secured to a closed end of the bellows and a finger abutment at an opposite end of the bellows.

3. A non-invasive medical probe as claimed in claim 2, wherein the finger abutment comprises a pair of wings projecting laterally for engagement by second and third fingers of an operator.

4. A non-invasive medical probe as claimed in claim 1, wherein the electrode includes a plate having a rim with a plurality of protrusions to enhance electrical contact with the skin in the presence of hair.
