A fetal heart rate electrode assembly, a connector for use therewith and a cable assembly including a housing assembly configured for engagement with the connector. The electrode assembly includes a drive knob configured and located for selective extension of a fetal scalp electrode beyond a distal end thereof. The connector comprises a rotationally omnidirectional contact assembly disposed within a dielectric housing including an annular groove on the exterior thereof The housing assembly includes longitudinally resiliently biased pin contacts for end face contact with the contacts of the connector disposed within an inner housing of the housing assembly having an O-ring and an annular retention element positioned to respectively wipe the exterior of the connector housing and grasp the connector housing at the annular groove when the connector is inserted thereinto. A system and methods of use are also disclosed.

Fetal heart rate electrode assembly, connector for same, cable assembly, system, and methods of use

A urodynamic catheter incorporating at least one balloon adjacent a distal end thereof and associated with a pressure lumen extending to a proximal end to be placed external to the body of a patient and usable with a transducer housing including a pressure transducer and a mechanism for alternatively venting an air column defined by the assembled pressure lumen and transducer housing to the ambient environment and closing the air column and charging it with air while reducing volume of the air column. One embodiment includes two, separately-chargeable balloons and a bladder fill tube, another embodiment includes a single balloon and a fill tube, and yet another embodiment, suitable for use as a reference catheter to measure abdominal pressure, includes only a single balloon and omits the fill tube. A novel catheter architecture and assembly technique are also disclosed, as are methods of using the inventive catheter.

Urodynamic catheter and methods of fabrication and use

A method and apparatus for collecting blood from a fetal scalp. The apparatus includes an elongated housing containing a longitudinally spring-loaded, sharp-pointed, beveled blade disposed at the distal end thereof which can be advanced against the spring bias from the distal end against the fetal scalp. A groove located on an exterior side surface of the distal end of the housing is sized to receive a capillary tube which is resiliently retained on the housing with its distal end proximate a recessed region at the distal end of the housing. The groove may be oriented parallel to the housing, or at an angle thereto, to enhance visualization of blood pooling in the recessed region filling the capillary tube after an incision in the scalp is made using the blade. A light source may be included in or on the apparatus, or on the interior of an amnioscope with which the apparatus is employed. A method of using the apparatus is also disclosed.

A pressure catheter for monitoring changes in pressure within the body is comprised of an outer tube containing a fluid channel and a closed air column having a pressure-compliant member which is deformable upon an increase in pressure. A change in pressure deforms the pressure-compliant member, which modifies the pressure in the air column, and is translated to a pressure sensor, which converts the pressure change data to an electrical signal recognizable by a fetal monitor. The outer tube employs a window extending along at least a portion of the side thereof for viewing of bodily fluids moving through the fluid channel from the body in which the catheter is inserted toward the proximal catheter end. The pressure catheter of the present invention is particularly suitable for intrauterine pressure monitoring during labor. Viewing of amniotic fluid through the window facilitates verification of proper catheter tip placement within the amniotic fluid space. Venting closures for facilitating venting of fluid through the channel are also disclosed.

An electronic calculator is disclosed for calculating important obstetrical dates based on the entry of certain variables or information. The electronic calculator is structured to accept input relating to the last menstrual period, conception date, estimated date of confinement and estimated gestational age. The entry of any one of these variables of information, along with the entry of a reference date, allows the calculator to calculate the other, remaining variables. The electronic calculator provides information similar to that conventionally obtained from an obstetric wheel or birth wheel, but additionally provides for the capability of recalculating and updating the obstetric dates based on new or additional information input into the calculator. The dates calculated using the invention are, therefore, more accurate and can be stored in memory for recall at each subsequent obstetrical visit. The calculator can also be used to calculate and schedule future dates for testing or observance based on the input and calculated variables.

A system and method for multiplexing two lumens of a catheter to a single pressure transducer and monitor setup such that the pressure found in either of the two lumens may be alternately monitored. Included in the present invention is a pressure multiplexing valve provided with a four-port body and a rotor which may be selectively rotated to either of two monitoring positions. The rotor is provided with passageways that interconnect the ports. In one embodiment both catheter lumens are always connected to a medical infusion device regardless of which lumen is connected to the transducer. In another embodiment, one lumen is shut off when not connected to the transducer. The present invention provides a compact system removably mounted on a single carrier.

A method of accurately mixing gases in desired proportions which comprises establishing the gases to be mixed at a uniform pressure; sequentially feeding the gases through a common restrictor for proportionate time periods to give the gas mix desired. The apparatus used includes a pressurizing gas reservoir unit which adjusts all gases to be mixed to have a common pressure; electronically actuated rapid response fluidic interface valves; a common restrictor through which the gases are passed to a receiving and mixing chamber; and timing means controlling the valves to allow gases to be sequentially passed therethrough for pre-set time periods.
