摘要： A calibration system and method for calibrating a medical sensor (16) that monitors chemical blood gases. A calibrator (12) is used in connection with a tray (14) in which the medical sensor is stored in a sterile environment, both before and during the calibration process. The medical sensor is immersed in a liquid (30) in a tonometry chamber (28) defined in the tray and covered by a membrane (120/122) that is permeable to gas, but impermeable to bacteria. During the calibration process, the tray is inserted into the calibrator, bringing a heated platen (26) into contact with the tonometry chamber, so that the liquid can be heated to a calibration temperature substantially equal to the temperature at which the medical sensor will subsequently be used. A first calibration gas is then bubbled through the liquid until a saturated condition is achieved. Once the temperature of the liquid is increased to the desired calibration temperature, as determined by a temperature sensor on the medical sensor, data for a first calibration point is taken. A second calibration gas is then bubbled through the liquid until saturation is achieved, yielding data for a second calibration point, for each of the chemical blood gas parameters. The calibration data is processed to determine calibration coefficients that will be applied to the medical sensor.

摘要： A pressure monitoring apparatus for use in monitoring a physiological fluid pressure in successive patients. Three embodiments of the pressure monitoring apparatus (10, 100, 200) are disclosed, each of which include a disposable portion ( 12, 12', 12") and a reusable portion ( 14, 14', 14"). Fluid flows through the disposable portion and into a cavity (48) that is covered with an elastomeric membrane (46, 46'). When the disposable portion is engaged with the reusable portion, the elastomeric membrane is in contact with a corresponding elastomeric membrane (50, 50'), which covers a pressure sensing cavity (52). A pressure transducer (56) is mounted in the pressure sensing cavity, and the pressure sensing cavity is filled with a fluid and is in fluid communication with a reservoir(38) when not engaged with the disposable portion. When the disposable portion is brought into engagement with the reusable portion, a passage (54, 53) connecting the reservoir with the pressure sensing cavity is blocked, thereby minimizing the volume of fluid within the pressure sensing cavity. In this way, the compliance of the pressure sensing portion is reduced, so that its frequency response is increased. In one embodiment of the pressure monitoring apparatus (100), a slider (110) is provided for covering the elastomeric membrane used on the disposable portion so that exposure of the elastomeric membrane to a fluid pressurized to a level in excess of the rated pressure for the membrane does not damage the membrane.

摘要： A device for storing and delivering a sensor through a catheter. A sensor delivery device (10, 10') includes an elongate tube (20), which is attached to a rigid housing (22,22'). A sensor (12), stored within a sterile environment comprising an interior of the sensor delivery device, has an attached signal line (16) that extends along the longitudinal axis of the delivery device and through its proximal end. The proximal end is open when the sensor is in its stored position. An eversible sheath (34) extends between the rigid housing and the signal line, sealingly separating the sterile environment (48) in which the sensor is stored from the open end of the rigid housing. To use the sensor, the signal line is moved into the rigid housing, causing the eversible sheath to turn inside out as the sensor is advanced through the catheter into its use position. The projection afforded by the eversible sheath permits the sensor to be withdrawn through the catheter and then reinsertd without introducing contamination. A probe stop (54) abuts an inner surface of a catheter fitting ( 17), precisely controlling the distance that the sensor extends beyond a distal end of the catheter.

摘要： A method for aligning first and second optical fibers of a fiber optic connector at a fiber interface wherein the first optical fiber has a beveled angle end face and the second optical fiber a complementary beveled angle end face, the method including the step of abutting the respective fiber end faces at an angle at the interface, cooperatively engaging a vertical reference surface associated with the first optical fiber with a vertical reference nodule associated with the second optical fiber to align the respective fiber end faces at a vertical aligned position for the connector. Respective horizontal reference surfaces associated with the first optical fiber are also cooperatively engaged with a horizontal reference node and a compressible crush rib associated with the second optical fiber to align the respective fiber end faces at a horizontal aligned position for the connector. The method also holds the respective fiber end faces in suitable connector members in abutting and full engagement at the fiber interface, within a connector enclosure, in a fixed aligned position, in which the vertical aligned position is coincident with the horizontal aligned position for the optical fibers of the connector.

摘要： A process for flushing clots from an intravascular probe including the steps of positioning a catheter assembly in a blood vessel and then delivering a flushant through the catheter and past the probe at two rates. The flushant is first delivered at a continual rate to maintain the catheter substantially free of blood clots. Periodically, a pulse of flushant is delivered at a second flow rate that is higher than the continual rate that is effective to clear the probe of incipient clots. The hydrodynamic clot flushing system includes a cather insertable within an arterial or venous blood vessel, the cather having an internal axial bore for conducting fluid and in which a probe is slidably received. A valve delivers a flushant through the internal axial bore of the catheter and around the probe at two selected rates. A plurality of radially arrayed ribs formed on either the internal wall of the catheter or the outside of the probe or both hold the probe away from the wall and provide fluid channels for conducting flushant to the probe tip.

摘要： Apparatus and a method for monitoring a percentage of the oxygen saturation in the hemoglobin of blood flowing through a blood vessel. An optical sensor that detects the percentage oxygen saturation in blood is disposed proximate a proximal end of the catheter. A thermistor is disposed adjacent to the distal end of the catheter and it is employed to detect changes in blood temperature that indicate the position of the catheter's distal end in the blood vessel. Indicia or marks visible at intervals on the outer surface of the catheter enable a medical practitioner to determine the length of the catheter that has been introduced into the blood vessel. A strain relief that is flexible and resists stretching extends along the length of the catheter. For flushing the distal end of the catheter, a fluid supply may be connected to a lumen running through the catheter to provide the flushing fluid. A removable guide wire is inserted in the lumen when positioning the distal end of the catheter at a location in the blood vessel and provides enhanced rigidity for this purpose. The catheter may be coated with an anticoagulant such as heparin, to prevent blood from coagulating on the exterior surface of the catheter.

摘要： An improved armboard includes receptacles for receiving and holding a medical device to be used in conjunction with the treatment of a patient. The patient's forearm is immobilized on the armboard, a sensor associated with the medical device is inserted into the patient, with a side channel of the armboard holding the medical device and a cable extending from the sensor to a fiber optic connector received in a modular unit stored in a suitable cavity and optical cable channels extending from opposite ends thereof are appropriately sized to prevent misinsertion of the modular unit into the armboard. The armboard is formed from polystyrene foam, and thus is lightweight, disposable after a single use, and the cavities provided therein are appropriately sized to receive and retain the components of the medical device associated therewith.
