摘要： 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.

摘要： A hand-held fetal vacuum extractor combines a pump and handle into a single hand-held unit. This enables a single operator, such as a doctor, to control vacuum using a vacuum pump, and apply traction to a fetus using a single hand. A handle, having a surface for gripping, is connected to a fetal vacuum cup for being suctioned onto a fetal head. A vacuum pump is connected to the handle and includes an activation surface for activating the vacuum pump. The vacuum pump is fluidly coupled to a the vacuum cup and fetal head. The grip surface of the handle and the activation surface of the pump are in such proximity, during operation, that a single human hand can simultaneously grasp the grip surface and contact the activation surface.

摘要： A vacuum extractor for use in childbirth is described. The vacuum extractor includes a handle and a vacuum cup with a force sensor coupled to the vacuum extractor. The force sensor measures the traction force applied between the vacuum cup and the handle for assisting the birthing attendant in applying an appropriate traction force. The force sensor may also include a slipping mechanism which causes the length of the force sensor to distinctly increase if the applied traction force exceeds a certain level such as twenty pounds. Thus, the birthing attendant may feel the slipping and thus determine that the traction force has exceeded the certain value.

摘要： The fetal contact cup portion of a fetal vacuum cup has an inside surface which, when applied to a fetal head, defines a fetal contact chamber with the fetal head. One end of a tube is attached to the fetal contact cup such that vacuums within the tube are applied within the fetal contact cup. The other end of the tube can be connected with a vacuum source and with a handle. The tube has a very small average outside diameter compared with conventional fetal vacuum tubes. Thus the fetal vacuum cup is less intrusive during insertion and is more easily maneuverable, especially when the fetus is malpresenting in, for example, the high occipitoposterior or high occipitolateral positions. The average outside diameter of the tube may be, for example, less than 150 mils and has a finger grip that compression fits into a recess defined by the outer surface of the fetal contact cup for a lower profile and easy positioning of the fetal contact cup onto the flexion point of the fetal head. During traction, however, the finger grip pulls out of the recess for more efficient traction. The fetal contact cup may have a soft lip for contacting the fetal head. Furthermore, the tubing may have markings to indicate proper positioning of the fetal vacuum cup over the flexion point.
摘要翻译：胎儿真空杯的胎儿接触杯部分具有内表面，当其应用于胎儿头部时，该表面限定了与胎儿头部的胎儿接触室。管的一端连接到胎儿接触杯，使得管内的真空被施加在胎儿接触杯内。管的另一端可以与真空源和手柄相连。与常规胎儿真空管相比，该管具有非常小的平均外径。因此，胎盘真空杯在插入过程中侵入性较差，并且更容易操作，特别是当胎儿在例如高枕骨前后或高枕骨外侧的位置发生畸形时。管的平均外径可以是例如小于150密耳，并且具有手指把手，其压缩配合到由胎儿接触杯的外表面限定的凹部中，用于下部轮廓并且容易定位胎儿接触杯到胎头的屈曲点。然而，在牵引期间，手指把手从凹槽中拉出以获得更有效的牵引力。胎儿接触杯可以具有用于接触胎儿头部的软唇。此外，管道可以具有标记以指示胎盘真空杯在弯曲点上的正确定位。

摘要： An optical measuring device having multiple optical paths between one or more light emitters and one or more light detectors and/or providing at least two sets of wavelength of light along at least one path, with a final measurement being produced as a combination of measurements of the sets of wavelengths of light taken along one or more of the optical paths. Features that contribute to increased safety and ease of use include providing (1) a receiving cavity in a proximal end of an insertion rod that holds a free end of a circuit connector to keep it from becoming tangled or snagged, (2) a mechanism to keep the sensor within an introducer tube during storage and insertion and to expose a portion of the sensor only when the sensor is applied to the unborn baby, (3) a tab on the insertion rod to prevent the circuit connector from becoming tangled or snagged within the introducer tube, (4) a rotating feature whereby if a torque applied on the sensor exceeds a first predetermined amount, the sensor rotates, and a disengaging feature whereby the sensor detaches from insertion rod if a pull-off force exceeds a second predetermined amount, the rotating and disengaging features being independent of one another, (5) a circuit connector that includes at least one of the following features: (a) a stiffening member provided at the proximal end to minimize bending, (b) a shielding layer, and (c) at least one slit to increase the flexibility of the circuit connector, and (6) an interface that includes an identification element that is detected by an external circuit only if the circuit connector is connected to the interface. The present invention also pertains to a method of manufacturing a needle that is used in an invasive sensor, and preferably for fetal monitoring, that provides features not heretofore available in conventional sensors.
