Abstract
The measuring head enables the production of measuring signals relating to electrical activity and measuring signals relating to an ionic or physico-chemical activity, notably pH, and is designed to be located on or in parts of a living body, notably on the head of an unborn infant. It comprises an insulating body bearing fastening claws. At the moment of positioning, the insulating body introduces actively an electrode sensitive to the electrical activity and at least one electrode sensitive to an ionic or physical activity. These electrodes are constructed in needle form, body body having also a reference electrode associated with the electrode sensitive to the ionic or physical activity.
Claims32
A measuring head adapted to be positioned on or in corporeal parts of a living body, said head comprising:
- an insulating body,
- said insulating body having a first electrode means which is sensitive to electrical activity of said corporeal parts, an electrical lead operatively connected to and extending from said first electrode means,
- said insulating body also having a second electrode means which is sensitive to an ionic or physical activity of said corporeal parts, an electrical lead operatively connected to and extending from said second electrode means,
- an elongated sheath means being connected to and extending from said insulating body, said electrical leads extending from the insulating body along said sheath means,
- said insulating body having a claw means movable between a retracted position within said insulating body and an extended position out of said insulating body whereat it is positioned to enter the corporeal parts, to thereby secure the measuring head to the corporeal parts,
- control means for moving the claw means between said retracted and extended positions such that in the said extended position the claw means has entered the corporeal parts while said first and second electrode means simultaneously engage the corporeal parts.
A measuring head adapted to be positioned on or in corporeal parts of a living body, said head comprising an ovoid insulating body having an elongated base with a flare bottom part, said base being traversed by an orifice slightly inclined with respect of said bottom part, a reciprocating electrode means slideably received in said orifice, said electrode means being sensitive to an ionic or physical activity of said corporeal parts, said electrode means having a needle form and being provided with an outer tubular conductive member which is sensitive to the electrical activity of said corporeal parts, electrical lead means for said electrode means, a removable ovoid cap on said base, at least one curved needle forming a claw mounted on said body, an elongated sheath means connected to said insulating body and surrounding said electrical lead means, and means, including an elongated mechanical member movable in said elongated sheath means extending from said base, and operatively connected to the claw, for moving said electrical means and said at least one claw between a retracted position in said body and an extended position wherein they penetrate into said corporeal parts following directions approaching one another.
