Abstract

Abstract An instrument for monitoring foetal heart rate having a head member (2) for application to the foetal scalp, the head member (2) having two jaws (24,25) which are hingedly connected to one another, the first jaw (24) having an arcuate electrically conductive needle (9) extending therefrom and movable therewith for penetration of the foetal scalp. A wire (6) extends from the needle (9) to a terminal for connection to monitoring equipment. A second wire (7) is insulated from the first (6) and extends between an exposed electrode sheath (11), for contacting the mother in use, and a terminal for connection to monitoring equipment. The instrument also has actuating means, in the form of a telescopic arrangement of elongate members (1,15), for moving the jaws (24,25) apart. The jaws (24,25) are moved back to a preselected attitude by the bias provided by a resilient membrane (27).

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 114 words
An instrument for monitoring foetal heart rate comprising a body having a head member (2) for application to the foetal scalp, an electrically conductive needle (9) extending from the head member for penetration of the foetal scalp, a first electrical conductor (6) extending from the needle (9) for connection to monitoring equipment, a second electrical conductor (7) for connection to monitoring equipment, said second conductor being insulated from the first conductor (6) and extending from a terminal (11) external of the body for contacting the mother in use, characterised in that the head member is flexible and the needle is movable therewith, and actuating means (4) are provided for flexing the head member (2).
Claim 2
Dependent Claim 114 words
An instrument for monitoring foetal heart rate comprising a body having a head member (2) for application to the foetal scalp, an electrically conductive needle (9) extending from the head member for penetration of the foetal scalp, a first electrical conductor (6) extending from the needle (9) for connection to monitoring equipment, a second electrical conductor (7) for connection to monitoring equipment, said second conductor being insulated from the first conductor (6) and extending from a terminal (11) external of the body for contacting the mother in use, characterised in that the head member is flexible and the needle is movable therewith, and actuating means (4) are provided for flexing the head member (2).
Claim 3
Dependent Claim 27 words
An instrument as claimed in Claim 1, wherein biassing means are provided on the head member (2), to bias said head member (2) towards a preselected attitude.
Claim 4
Dependent Claim 24 words
An instrument as claimed in Claim 1 or 2, wherein the biassing means comprises a resilient membrane (27) which engages the head member (2).
Claim 5
Dependent Claim 47 words
An instrument as claimed in any one of the preceding Claims, wherein the actuating means (4) is in the form of a telescopic arrangement of members (1,15), the members (1,15) being connected with different regions of the head member (2) for flexing said head member (2). 30
Claim 6
Dependent Claim 29 words
An instrument as claimed any one of the preceding Claims, wherein the flexible head member (2) comprises first and second portions (24,25) which are hingedly connected to one another.
Claim 7
Dependent Claim 34 words
An instrument as claimed in Claim 5, wherein the needle (9) is arcuate and centred on the axis of the hinge connection (28) between the first and second portions (24,25) of the head member(2).
