The invention is a device for the introduction of a fluid into a human's airway. The air so introduced has a carefully modulated envelope of pressure vs. time, this envelope generally consisting of sequences of pressurized air packets of controlled frequency and pressures. The device produces these packets by means of pressurized air occluded by a shutter action which “chops” and interrupts the fluid stream. The vibrations induced by the device within human organs have been shown to have beneficial effects on various bodily systems, such as increase in heart rate variability, increase in absorbed oxygen, decrease in absorbed CO2, and the like.

Process for the automatic control of a respirator

Номер: US20120152249A1

Автор: Frank Sattler, Hans-Ullrich Hansmann, Marcus Eger, Tobias GLAW

Принадлежит: Draëger Medical GmbH

A process for the automatic control of a respirator with a changeover between phases of respiration (inspiration and expiration), by a control unit checking a breathing activity signal for a threshold criterion. If the threshold criterion is met, a changeover is made and the control unit controls the fan of the respirator such that a pneumatic respiration variable (airway pressure, flow) is brought from an actual value to a preset target value for the new phase of respiration. The control unit further divides the change in the respiration variable, from the actual value to the target value, into a plurality of partial steps and checks the current breathing activity signal for the threshold criterion after each partial step. If this threshold criterion is no longer met, the state of operation of the respirator returns to the state before the last changeover, and otherwise, continues with the next partial step.

Method and apparatus for machine error detection by combining multiple sensor inputs

Принадлежит: Nxstage Medical Inc

One of the most significant safety concerns in the automation of extracorporeal blood treatments such as dialysis is the risk of blood leakage. Extracorporeal blood treatment systems draw blood at such a high rate that a loss of integrity in the blood circuit can be serious. There are a number of mechanisms for detecting and preventing leaks, but none is perfect. This tends to limit the use of such equipment in unsupervised settings, such as the home will be limited. Some leak detection schemes can be made sensitive enough to detect the barest of leaks, but when this is done, they result in too many false positives. The invention combines information from multiple inputs to enhance sensitivity in leak detection and reduce the problem of false positives.

As a gas-containing fluid flows through an internal passage of the tube, a drive signal vibrates the freestanding tube portion at a resonant frequency thereof. Coriolis-induced deflections of the freestanding tube portion are sensed relative to the substrate to produce an output corresponding to the sensed deflections, and the drive signal and/or the output are assessed to determine the volume, density and/or flow rate of the gas of the gas-containing fluid.

Принадлежит: Dexcom Inc

Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

Some embodiments an infusion pump system can be used to determine a user's total insulin load (TIL) that provides an accurate indication of the insulin previously delivered to the user's body which has not yet acted. In particular embodiments, the TIL can account for both the bolus deliveries and the basal deliveries that have occurred over a period of time. Such information may be useful, for example, when the infusion pump is operated in conjunction with a continuous glucose monitoring device.

A system and method for managing a herd of animals possibly requiring medical treatment, such as cows in a feedlot. The animals are herded individually into a chute, where identification data is collected from a tag, and core temperature data is collected using a special non-contacting core temperature sensor. The animal is tagged with a color coded tag representing a range of temperatures into which that animal's temperature falls. The animal is then delivered to a pen corresponding to that range of temperatures, where appropriate medicinal treatment is automatically dosed and applied to the animal.

Принадлежит: ResMed Pty Ltd

A modularized respiratory treatment apparatus provides various respiratory pressure treatments. The apparatus may be formed by discrete connectable modules such as a flow generator module, alarm module and/or humidifier module. Each module may include its own external casing or housing to independently retain or enclose the respective components that serve the function of the module. Different modules may be adapted with different components and functionalities and may be readily coupled using standardized gas and electrical connection configurations that have flow and communication paths that extend through the modules. When coupled, operation of the respiratory treatment apparatus may be controlled by detection of different modules, such as the alarm module that generates visual and/or audible alarms based on detected conditions, so as to selectively enable or disable different respiratory treatments. The discrete modules of the medical treatment apparatus may include tamper resistant locking mechanisms to impede unauthorized separation of some modules.

Embodiments of the present disclosure provide a hypersaturation index for measuring a patient's absorption of oxygen in the blood stream after a patient has reached 100% oxygen saturation. This hypersaturation index provides an indication of the partial pressure of oxygen of a patient. In an embodiment of the present invention, a hypersaturation index is calculated based on the absorption ratio of two different wavelengths of energy at a measuring site. In an embodiment of the invention, a maximum hypersaturation index threshold is determined such that an alarm is triggered when the hypersaturation index reaches or exceeds the threshold. In another embodiment, an alarm is triggered when the hypersaturation index reaches or falls below its starting point when it was first calculated.

The efficacy of these agents is measured by their ability to create anesthesia within the framework of the other desirable properties. The instant invention focuses on the dosage level where analgesia occurs but amnesia or lack of consciousness does not. In addition to identifying the dosage level where pain is sharply reduced or eliminated but awareness remains, a delivery system for safe and effective delivery of the agent is described.

Assessment and treatment of respiratory fatigue

Автор: Christopher Page, Jean Remy BONNEFOY, Ralph Page, Tariq Rahman, Thomas H. Shaffer

Принадлежит: Nemours Foundation

Objective Pulmonary Function (PF) evaluation for respiratory fatigue is vital to the diagnosis and management of many pediatric respiratory diseases in the intensive care, emergency and outpatient settings. A non-invasive PF instrument utilizes sensors and software to access respiratory breathing patterns, vital parameters, asynchrony and measures the work of breathing. Software algorithms predict respiratory fatigue. The hardware includes a microcircuit board that individually links to rib cage (RC) and abdominal (ABD) inductance bands. The bands wirelessly transmit changes in RC and ABD circumference. Point-of-care, real-time indices of respiratory work, breathing patterns and respiratory fatigue indices are developed on a user-friendly graphical user interface. The diagnostic data can later be securely emailed as an attachment for entry into patients' electronic medical records or sent to a caretaker's computer, or used directly to control a respiratory therapy device. The system can also be used for telemedicine homecare.
