  • Publication number: 20130345539
    Abstract: A lightweight, disposable and substantially radiolucent electrode or sensor assembly for that universally connects to separate, non-integrated electrodes or sensors for the monitoring of the physiological parameters of a live subject wherein the electrode assembly is comprised of one or more radiolucent electrical connectors for connecting the electrode assembly to the sensors. The present invention also discloses a method of positioning the electrode assembly on a patient whose physiological signs are being monitored such that access to the patient's chest is substantially unimpeded so as not to obstruct the electromagnetic imaging of the patient's chest, the application of defibrillation paddles or surgical procedures that require access to the chest area.

  • Patent number: 8577439
    Abstract: A system for positioning electrodes on a patient body includes an image capturing system, a memory device, a processing system and an indicator system. The image capturing system generates an actual image of the patient body. The memory device stores a reference image, the reference image including a reference body and a reference position on the reference body. The processing system compares the actual image and the reference image and for determining an electrode position on the patient body by matching the reference position on the reference body. The indicator system indicates the electrode position on the patient body.

  • Patent number: 8326434
    Abstract: A medical electrical lead electrode assembly includes an insulative carrier and at least one conductive component. The at least one conductive component includes an electrode portion disposed on a first side of the carrier and at least one tab extending away from the electrode portion, through the carrier to a second side of the carrier. The electrode portion of the at least one component includes an outward facing contact surface and an inward facing surface, the inward facing surface being disposed opposite the contact surface and against a surface of the first side of the carrier. The electrode assembly further includes a joint coupling a flexible elongate conductor to the tab of the at least one component on the second side of the carrier, and an insulative layer extending over the joint and the tab and the conductor, the insulative layer being bonded to the second side of the carrier.

  • Patent number: 8118807
    Abstract: A biomedical return electrode for electrosurgery or radiofrequency (RF), a biomedical electrode pad (100), a system (300), and a method of treating tissue using a biomedical return electrode are disclosed. The biomedical return electrode comprises an electrode conductor (114) for receiving electrical energy from tissue via a return path, and a thermochromic liquid crystal (TLC) layer (116) coupled to the conductor (114). The TLC layer (116) changes color at one or more sites dependent upon the conductor temperature at each site. The TLC layer (116) changes color in a predetermined range of temperatures from about 40° C. to about 50° C. to alert an operator about the risk of a burn occurring. The biomedical electrode pad (100) comprises at least one such biomedical return electrode and a conductive body (112) to form a contact with tissue. The system (300) comprises an apparatus for delivering electrical energy to tissue and such a biomedical electrode pad (100).

  • Patent number: 7628761
    Abstract: An apparatus and method for detecting physiological function, for example, nerve conduction, is described. In one embodiment the apparatus includes a housing including a stimulator shaped to fit a first anatomical site and a detector shaped to fit a second anatomical site. The housing automatically positions the detector substantially adjacent to the second anatomical site when the stimulator is positioned substantially adjacent to the first anatomical site. The detector contains a plurality of individual detection elements, whereby the response evoked by stimulation at the first anatomical site is measured using one or more of these detection elements at the second anatomical location.

  • Patent number: 7162290
    Abstract: A method and apparatus for periodically and automatically testing and monitoring a patient's blood glucose level. A disposable testing unit is carried by the patient's body and has a testing chamber in fluid communication with infusion lines and a catheter connected to a patient blood vessel. A reversible peristaltic pump pumps the infusion fluid forwardly into the patient blood vessel and reverses its direction to pump blood into the testing chamber to perform a glucose level test. The presence of blood in the testing chamber is sensed by a LED/photodetector pair or pairs and when the appropriate blood sample is present in the test chamber, a glucose oxidase electrode is energized to obtain the blood glucose level. The resulting glucose level is displayed on a monitor. The unit is typically used for a patient in an intensive care unit.
