| 20100240973 | BLOOD OXIMETER - The invention relates to a blood oximeter for measuring the oxygenation and at least one other parameter of flowing blood in living tissue. According to the invention, the blood oximeter comprises two lightsources ( | 09-23-2010 |
| 20110046464 | PHOTOPLETHYSMOGRAPHY WITH CONTROLLED APPLICATION OF SENSOR PRESSURE - Systems, methods, and devices for obtaining consistently reproducible diagnostic measurements with a photoplethysmographic sensor are provided. In one embodiment, a method for obtaining such a diagnostic measurement includes applying a pressure between a photoplethysmographic sensor and a patient, increasing the pressure until the photoplethysmographic sensor outputs a plethysmographic waveform of minimal amplitude, decreasing the pressure by a predetermined fraction, and obtaining a diagnostic measurement using the photoplethysmographic sensor. The pressure may be applied using a pressure device that includes, for example, a clip, a wrap, an inflatable balloon or bladder, or an inflatable cuff or any combination thereof. | 02-24-2011 |
| 20110275916 | Control solution packets and methods for calibrating bodily fluid sampling devices - A control solution packet for calibrating a bodily fluid sampling device includes a container, a control solution pressurized within the container, and a membrane for covering and sealing the container. The control solution can be pressurized before or during calibration so as to ensure the appropriate amount of control solution is delivered to the bodily fluid sampling device. The control solution is manufactured to have a viscosity that controls delivery of the control solution to the device. The membrane is permeable by a piercing device of the bodily fluid sampling device and seals around the piercing device during calibration. In another aspect, the container is in the form of a capsule or dosing attachment that contains the control solution along with a sponge-like material. | 11-10-2011 |
| 20110319732 | Ischemic Conditioning for Improved Athletic Performance - Methods for ischemic conditioning treatments of a chronic medical condition are provided. Baseline disease-related parameters of a patient with a chronic medical condition are measured. Ischemia is induced in the patient by occluding and releasing arterial flow in one or more extremities of the patient. Post-ischemia parameters in the patient are measured. The baseline and post-ischemia parameters are compared to provide an assessment of an ischemic conditioning treatment of a chronic medical condition. The repeated, scheduled delivery of ischemic conditioning provides a beneficial, therapeutic effect on the chronic medical condition. Also provided is a device for pulse oximetry during periods of absent or low pulsatile blood flow including an artificial pulse generator as well as the use of said device in assessment of ischemic conditioning. | 12-29-2011 |
| 20120215082 | METHOD AND APPARATUS FOR NONINVASIVE BLOOD PRESSURE MEASUREMENT USING PULSE OXIMETRY - Embodiments of the present disclosure relate to a system and method for determining a physiologic parameter of a patient. Specifically, embodiments provided herein include blood pressure cuffs that are adapted to be used in conjunction with a photoplethysmography sensor. The cuff as provided may be configured to be placed over the sensor and/or aligned in a specific manner relative to the sensor. Alternatively, the cuffs may include integral optical components. | 08-23-2012 |
| 20130085356 | SENSOR SYSTEM WITH PRESSURE APPLICATION - Embodiments of the present disclosure relate to sensors for applying pressure to a patient's tissue. According to certain embodiments, the sensors may include one or more deformable elements that hold the optical components of the sensor against the tissue with an appropriate amount of pressure. In additional embodiments, such sensors may include a rigid one-piece sensor body that incorporates a deformable element to facilitate fine-fitting of the sensor against the tissue. | 04-04-2013 |
| 20130289371 | PHOTOPLETHYSMOGRAPHY WITH CONTROLLED APPLICATION OF SENSOR PRESSURE - Systems, methods, and devices for obtaining consistently reproducible diagnostic measurements with a photoplethysmographic sensor are provided. In one embodiment, a method for obtaining such a diagnostic measurement includes applying a pressure between a photoplethysmographic sensor and a patient, increasing the pressure until the photoplethysmographic sensor outputs a plethysmographic waveform of minimal amplitude, decreasing the pressure by a predetermined fraction, and obtaining a diagnostic measurement using the photoplethysmographic sensor. The pressure may be applied using a pressure device that includes, for example, a clip, a wrap, an inflatable balloon or bladder, or an inflatable cuff, or any combination thereof. | 10-31-2013 |
| 20150313517 | ENDOSCOPE SYSTEM - The invention provides an endoscope system for generating an oxygen saturation image that can be used for various medical applications, such as oxygen saturation monitoring during surgery. A clip | 11-05-2015 |
| 20160029900 | METHOD AND SYSTEM FOR ASSESSING SEVERITY AND STAGE OF PERIPHERAL ARTERIAL DISEASE AND LOWER EXTREMITY WOUNDS USING ANGIOSOME MAPPING - The present invention provides a system for assessing the severity and stage of PAD including at least one sensor that measures skin perfusion pressure; a knowledge base that provides data on lower extremity angiosomes; and a processing device in operable communication with the sensor and the knowledge base, the processing device that outputs a visual representation of at least one of the lower extremity angiosomes that guides the sensor in the mapping of a testing site relative to a target vessel where the skin perfusion pressure measurement will be taken. | 02-04-2016 |
| 20160128634 | MEASURING SYSTEM AND METHOD FOR EVALUATING CONDITION OF PATIENT - A measuring system includes a first sensor, a second sensor, a first measurement value calculator that, based on a change of an amount of received light that is measured by the first sensor, calculates a first measurement value indicating an index related to a blood oxygen saturation or a blood refill time, a second measurement value calculator that, based on a change of an amount of received light that is measured by the second sensor, calculates a second measurement value indicating an index related to a blood oxygen saturation or a blood refill time, and a pressure controller that controls the first sensor and the second sensor so that a time difference between a start of compression release by the first sensor and a start of compression release by the second sensor is within a predetermined time period. | 05-12-2016 |
