摘要： A fluid pressure monitoring system for a balloon catheter includes a pressure transducer in fluid communication with the interior of the balloon. The pressure transducer includes elements for providing an electrical signal which is a function of the pressure in the interior of the balloon. An electronic digital display is responsive to the electrical signal from the pressure transducer to display the balloon pressure measured by the pressure transducer. The system is especially suited for coronary angioplasty in which a catheter is inserted through blood vessels in the human body to the vicinity of a stenosis. The catheter carries an inflatable balloon to the vicinity of the stenosis, where it is inflated, and the fluid pressure monitoring system of the present invention detects and digitally displays to the cardiologist the pressure inside the inflated balloon. The pressure transducer is interchangeable with standard pressure transducers such as those used for monitoring substantially lower pressure such as a person's blood pressure and the digital display is also used to display a person's blood pressure. Alternatively, the balloon pressure transducer may be used with standard blood pressure monitors.

摘要： An electrosurgical unit which combines an electrosurgical power generator and a filtered smoke removal system into a single compact instrument comprising an electrosurgical generator module and a smoke removal module. The electrosurgical generator module is designed specifically to accommodate an electrosurgical tool during LEEP or LLETZ procedures. The electrosurgical generator module provides power to the electrosurgical tool at a predetermined level. The smoke removal module removes and filters smoke from the site of the electrosurgery. A switching circuitry activates the smoke removal module substantially simultaneous to the activation of the electrosurgical tool so that the smoke removal module is activated automatically whenever the electrosurgical tool is activated. The switching circuitry also delays the deactivation of the smoke removal module for a predetermined amount of time after the electrosurgical tool has been deactivated. The electrosurgical tool alternatively can be connected, concentrically or in parallel, to a smoke evacuation tube in communication with the smoke removal module.

摘要： An electrical connector of extreme simplicity for coupling leads of a fetal scalp electrode to a cable of an electrical signal monitor. The connector includes a plurality of electrically isolated wiring frame components derived from a single wiring frame and thereafter insert molded into a connector body. The wiring frame components include a pair of signal pathways passing through the connector body to couple each lead of the fetal electrode to a corresponding conductor in the cable and a reference pathway through the connector body for effecting an electrical reference coupling with the body of the patient and communicating a reference voltage through the cable to the monitor. Integrally formed on the connector body is a pivotable lead retention wing and thereon a lead retention stub. By pivoting the retention wing into a position adjacent to the connector body, the retention stub along with a lead of the fetal scalp electrode is received and clamped into a lead retention recess. Other integrally formed features of the connector body facilitate coupling and any decoupling of the retention stub from the retention recess.

摘要： Metabolic gas monitoring apparatus and methods for measuring the metabolic rate in patients. The apparatus includes separate inlets for a calibration gas, inspired gas, and expired gas, and means for alternately introducing each gaseous sample into a thermoelectric cooler. The cooler is configured with relatively narrow passageways so as to contain a minimal amount of gaseous volume therein and thus provides for a more dynamic response time and for more accurate measurements. The apparatus further includes a carbon dioxide sensor and an oxygen sensor for measuring the concentration of carbon dioxide and oxygen, respectively, in the gaseous samples, and a microprocessor for comparing the measured concentrations of carbon dioxide and oxygen in the inspired gas and expired gas and for calculating the metabolic rate. Preferably, the oxygen sensor has a zirconium oxide differential electrode and a substantially equal pressure is maintained in a sample chamber and a reference chamber of the oxygen sensor.

摘要： Method and apparatus for gas-liquid equilibration (tonometry) in a transportable vessel. Specifically the method and device is concerned with tonometry of blood or buffer solution in a syringe. The compartment formed when a syringe plunger is partially inserted into a syringe barrel serves as a tonometer chamber where gas of known composition is bubbled through a liquid sample. Gas enters the chamber through small holes in the tip of the syringe plunger and bubbles upward through the sample. The syringe plunger itself is a second chamber which is used for heating and humidifying the gas prior to entering the tonometer chamber. The entire syringe is housed in a temperature controlled environment during equilibration. This environment allows observation of the entire tonometry process. After equilibration the syringe tonometer is easily removed from the heat controlled environment and is used as the sample's transport vessel. The syringe configuration allows easy entry of the sample into the target sytem, e.g. a blood gas analyzer.

摘要： An electrosurgical loop comprising an insulated shaft with an electrical contact at its proximate end and a pair of extending insulated prongs at its distal end. The extending prongs are configured to give the loop a "Y" shape and each end of a thin wire are connected to each prong to provide a wire loop. Disposed over the shaft in longitudinal sliding engagement is a depth gauge comprising a clasp, a longitudinal intermediate portion, and a transverse cross bar. The clasp may be retrofit to an existing electrosurgical loop and permits the removal of the depth gauge from the loop, if desired. The transverse cross bar is wider than the breadth of the wire loop and has a transverse slot oriented in the same plane as the wire loop through which the wire loop passes as the depth gauge is adjusted for various cutting depths. Disposed on the insulated shaft are markings serving as depth indicators to which the depth gauge may be moved slidably to effect cut depth control for the loop. The loop may be constructed by punching a series of shaft blanks from a conductive metal stock, and rolling the electrical contact prior to applying the insulation. Also, prior to applying the insulation, the wire loop can be connected to the shaft blank to maintain the flow of electrical current through the shaft into the wire loop.
