  • Patent number: 10632318
    Abstract: An external charger for an implantable medical device (IMD) is disclosed including a three-axis magnetic field sensor at the center of a primary charging coil. The sensor first senses a magnetic charging field produced by the coil with no IMD present (vector A). The sensor then senses the field in useful operation when such field is being provided to the IMD (vector B). From these vectors, a vector C is calculated representing the magnetic field reflected from the IMD. Vector C can be used to determine a vector D, representing the position of the IMD in physical space relative to the external charger. Information comprising one or more volumes can be stored in the external charger, and compared with vector D to determine whether charger-to-IMD positioning will provide an adequate amount of power to the IMD, and/or to provide an indication of charger-to-IMD alignment.

These devices include first and second chambers that receive respective portions of a blood sample via respective filters. The material of the filters prevents passage of red blood cells while permitting passage of blood plasma. One of the filters has one or more holes to permit the passage of whole blood. Thus, when an example device is presented with a sample of blood, one of the chambers contains whole blood and the other contains blood from which the red blood cells have been filtered. Electrodes in each of the chambers can then be used to detect the impedances of the whole blood and the filtered blood, and the detected impedances can be used to determine a hematocrit of the sample of blood.

  • Patent number: 10285596
    Abstract: A system for measuring the blood loss comprises a measuring device that determines a hemoglobin concentration of fluid within a container utilizing a light source and a light detector. The container receives blood and other fluids from a patient during a medical procedure. Light from the light source is passed through the blood and other fluids in the container and is detected by the light detector. Based upon a magnitude of light detected, a hemoglobin concentration of the fluid in the container can be determined. A volume-measuring device determines the volume of blood and fluid in the container. Knowing the hemoglobin concentration and volume of fluid in the container, the volume of patient blood loss in the container can be determined. The blood loss measuring device in combination with infusion systems maintains a real-blood volume status so that proper infusion of blood, crystalloid and/or colloid solutions occurs.

  • Patent number: 10219733
    Abstract: In this urine flow meter, a water wheel which is caused to rotate by a flow of urine from a urine flow passage tube is provided at a lower end side of the urine flow passage tube. The shape of a tip portion of the urine flow passage tube that causes urine to hit on the water wheel constitutes a nozzle part in which the tip-side is acutely processed, and an opening is formed in a sidewall surface of the tip-side. A guide is provided in a urine flow passage and is disposed in such a way that a tip of the guide is elongated as far as a tip-side region of the mine flow passage tube. The water wheel is caused to rotate by the flow of urine, and the urine flow rate can be detected on the basis of the rotation detection information.

  • Patent number: 10201644
    Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.

  • Patent number: 10149642
    Abstract: An integrated bodily-fluid-component analyzing apparatus includes a main body, a lancet holder connected to the main body so as to be movable back and forth along a predetermined movement path, a lancet removably attached to the lancet holder, and a test strip that is removably attached to the main body and is used to measure a component of the bodily fluid flowing from a pricked site of the living body pricked with the lancet. The movement path of the lancet holder and a bodily fluid inlet of the test strip face a specific position that is in a vicinity of the main body and at which the pricked site is to be placed. The apparatus further includes a pressing section that presses a portion of the living body adjacent to the pricked site so as to cause the bodily fluid to flow from the pricked site.

  • Patent number: 10143412
    Abstract: Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.

  • Patent number: 10123783
    Abstract: An apparatus includes a transfer adapter, a puncture member, a disinfection member, and a fluid reservoir. The transfer adapter has a proximal end portion and a distal end portion, and defines an inner volume configured to receive the puncture member. The transfer adapter is coupled to the disinfection member. The distal end portion of the transfer adapter includes a port fluidically coupled to the puncture member and configured to be placed in fluid communication with a bodily-fluid of a patient. The proximal end portion is configured to receive a portion of the fluid reservoir to allow the fluid reservoir to be moved within the inner volume between a first position, in which a surface of the fluid reservoir is placed in contact with the disinfection member, and a second position, in which the puncture member punctures the surface to place the puncture member in fluid communication with the fluid reservoir.

  • Patent number: 10105551
    Abstract: Various systems and methods are implemented for controlling stimulus of a cell. One such method is implemented for optical stimulation of a cell expressing a NpHR ion pump. The method includes the step of providing a sequence of stimuli to the cell. Each stimulus increases the probability of depolarization events occurring in the cell. Light is provided to the cell to activate the expressed NpHR ion pump, thereby decreasing the probability of depolarization events occurring in the cell.
