  • Patent number: 6368308
    Abstract: A syringe has a slide member slideably mounted on the barrel of the syringe, and the slide member is interconnected to a plunger that is slideably mounted in the barrel so that movement of the slide member effects simultaneous and corresponding movement of the plunger. This allows a syringe operator to perform aspiration and injection in sequence with one-handed operation of the syringe. The slide member is mounted near the leading end of the barrel in trailing relation to the leading end of the plunger so that the operator can see the leading end of the plunger and control its instantaneous position by sliding the slide member with a thumb or finger. The hand position of the syringe operator does not change, assuring that precise needle positioning can be made and maintained even during procedures such as sclerotherapy where needle positioning is critical.

  • Patent number: 6267753
    Abstract: Robotic manipulation of three-part plastic preparation assemblies automatically produces IV solutions which conform to a input specifications of a pharmacist located on site or remotely, including preparation telerobotically. The transparent plastic bag assemblies are stored in a magazine, and are extracted automatically one by one for preparation of individual prescriptions. A supply bag is prefilled with U.S.P. water and is connected through a valve to a mixing bag. Unit dose holders with medicaments and pH adjusting chemistries are dispensed into the mixing bag through an inlet where they are broken open by manipulation, and water is introduced. The bag contents are mixed by rotation of a magnetic mixing bar. The mixing bag is connected by a second valve through a filter to an administration bag. Negative pressure is applied to the administration bag to draw the solution through the filter. The administration bag is then heat sealed and severed from the filter for delivery to the patient.

  • Patent number: 6197001
    Abstract: The present invention is directed to a vascular access device for introducing a catheter in a blood vessel using a guide advancing mechanism. The device generally comprises a housing, an introducer needle, a catheter, a guide wire and an actuating means. The introducer needle of the vascular access device is used to penetrate the blood vessel. The actuating means is then initiated and the guide wire is steadily propelled into the blood vessel. Once the guide wire is in place, the catheter, which is concentrically placed over the introducer needle and guide wire, is uncoupled from the vascular access device and guided into the blood vessel by the guide wire.

  • Patent number: 6179813
    Abstract: A vascular access device for infusion of fluids into a patient. The device includes an introducer sheath having one or more side holes and the sheath can be used with a catheter in place through the sheath, with a dilator in place through the sheath, or with the sheath vacant. The device provides for a significant volume of infused fluid to exit the side holes. The side holes allow for the infusion of fluids, such as medications, to be directed to specific patient locations rather than to have the entire volume of infused fluid exit the distal end of the sheath tube.

  • Patent number: 6142974
    Abstract: A portable intravenous fluid warming system wherein the temperature monitoring and control is accomplished utilizing four monolithic IC thermosensors. The sensors operate in a serial multi-stage fashion with the first sensor functioning so as to provide a ramp or build up to the next stage thus smoothly and gently increasing the temperature of the fluid and reducing the dynamic range required for the final heater stage, thus ensuring a more accurate and consistent output temperature. Power FET's provide heater drive current from an unregulated DC input source. The sensor is coupled to a microprocessor that is factory preprogrammed with predetermined set points. The microprocessor will continuously determine the temperature so as to allow determination of when the desired temperature is reached and will adjust power to the FET as necessary to hold the temperature at the correct point without exceeding the temperature. Interfacing is provided to an optional external digital readout unit for monitoring.

  • Patent number: 6117099
    Abstract: Access recirculation in a shunt is determined quantitatively by a method in which a standard solution, such as a saline, is injected into a patient's bloodstream upstream of the shunt. At a point in the access line, a photometric measurement is conducted of the change in hematocrit (.DELTA.H) with respect to time. Electronic circuitry receives signals from the detector and compares the integrated area of .DELTA.H with respect to time of the standard solution initially flowing through the access and of the recirculated solution and provides display of access recirculation. In another aspect, access recirculation and access blood flow are quantitatively determined without injecting a solution into the bloodstream. In this aspect the extent of access recirculation and/or access blood flow is determined quantitatively by a method in which the dialyzer blood flow rate or the ultrafiltration rate (UFR) is changed and the corresponding change in concentration of a blood constituent is measured.

  • Patent number: 6110153
    Abstract: An infusion device with a disposable administration set which is inexpensive to manufacture. In the preferred embodiment of the present invention the disposable administration set has a plurality of elongated cam followers connected to a plate assembly, wherein the cam followers are displace in a predetermined sequence and forced against a delivery tube by cam means driven by rotary drive means. The device also includes an optical occlusion sensor which is synchronized to operate in phase with the movement of the cam followers to measure pressure within the delivery tube at one pump phase, thereby sensing downstream occlusions, and to measure vacuum within the delivery tube at a second pump phase, thereby sensing upstream occlusions. The occlusion sensor is optical, and measures the degree of total internal reflection at the interface of the tube and the plate assembly, occlusion in the tubing.

  • Patent number: 6106500
    Abstract: A needle-syringe assembly comprises an elongated, generally cylindrical barrel which forms a hollow nozzle located at the distal end of the barrel and which opens into the interior of the barrel. A plunger is slidably mounted in the barrel and forms a longitudinal cavity. A needle holder carries a hollow needle on the distal end, and the needle holder is slidably mounted in the longitudinal cavity of the plunger. The needle holder includes a lateral arm which extends between the plunger cavity and the barrel. A spiral channel or slot forms a guide surface which extends along a proximal end portion of the barrel for engaging the lateral arm of the needle holder and retracting the needle holder within the barrel in response to relative rotational movement between the barrel and the needle holder.

  • Patent number: 6102885
    Abstract: A device is described which allows simultaneous application of suction or vacuum for evacuation of fat with application of energy to the fat inside an opening in a cannula. A pair of electrodes is situated within the cavity of the cannula just under the surface of cannula tip opening(s) or as part of the walls of such openings. The electrodes are spaced to allow coagulation of fat entering the cannula. Irrigation may be applied in a continuous or discontinuous or intermittent stream within the cannula to cool the tip and facilitate removal of suctioned tissue and prevent buildup of debris on electrodes. A method for using the cannula to remove adipose tissue or fat destroyed by the energy application through the use of suction with mechanical motion of the cannula, with energy application and optionally with the use of irrigation is also disclosed.
