摘要： Methods of and devices for monitoring the treatment of a human or non-human animal are disclosed. These involve a chip-sized passive sensor which is adapted (a) to receive and to rectify an electromagnetic signal with a frequency of 1-2 Ghz directed from outside the body towards it and to derive its operating power directly from the electromagnetic signal, and (b) to use its thus obtained operating power to transmit data relating to treatment by wireless telemetry to a receiver external to the body of the human or non-human animal. The data transmitted by the sensor is then processed to provide information on the treatment.

摘要： A system determines heamtocrit transcutaneously and noninvasively. Disclosed are a finger clip assembly and an earlobe clip assembly, each including at least a pair of emitters and a photodiode in appropriate alignment to enable operation in either a transmissive mode or a reflectance mode. At least two, and preferably three, predetermined wavelengths of light are assed onto or through body tissues such as the finger, earlobe, or scalp, etc. and the extinction of each wavelength is detected. Mathematical manipulation of the detected values compensates for the effects of body tissue and fluid and determines the hematocrit value. If a fourth wavelength of light is used which is extinguished substantially differently by oxyhemoglobin and reduced hemoglobin and which is not substantially extinguished by plasmas, then the blood oxygen saturation value, independent of hematocrit, maybe determined. It is also disclosed how to detect and analyze multiple wavelengths using a logarithmic DC analysis technique. Then a pulse wave is not required. So this method may be utilized in states of low blood pressure or low blood flow.

摘要： System for withdrawing body fluid from a body part in particular the finger pad, comprising a compression unit that can be deformed when the body part is pressed against it and increases the internal pressure in a region of the body part, and a withdrawal device. Deformation of the compression unit partially converts the primary pressing movement into a secondary movement which leads to an increase in the internal pressure in a region of the body part. The invention also comprises a system for stimulating the outflow of body fluid using a deformable compression unit.

摘要： Sensors and monitors for a physiological monitoring system having capability to indicate an accuracy of an estimated physiological condition. The sensor senses at least one physiological characteristic of a patient and is connectable to a monitor that estimates the physiological condition from signals detected by the sensor. The sensor includes a detector for detecting the signals from the patient which are indicative of the physiological characteristic. The sensor is associated with a memory configured to store data that defines at least one sensor signal specification boundary for the detected signals. The boundary is indicative of a quality of the signals and an accuracy of the physiological characteristic estimated from the signals by the monitor. The sensor further includes means for providing access to the memory to allow transmission of the data that defines the at least one sensor boundary to the monitor.

摘要： An apparatus for removing tissue and/or other material from a patient, particularly a breast of a patient, is provided. The apparatus generally includes a handpiece and a tissue removal mechanism connected thereto. The tissue removal mechanism includes a cannula having an open distal tip and an outer diameter of less than about 5 mm, or less than about 2 mm. The mechanism further includes a rotatable element having a distal portion with helical threading. The distal portion of the rotatable element extends beyond the open distal tip of the cannula in order to allow tissue to prolapse between turns of the helical threading. The apparatus is designed to draw soft tissue into the cannula upon rotation of the rotatable element and without the need for supplemental sources of aspiration.

摘要： An interface system is provided for planning a surgical procedure for inserting an object into a patient along a surgical planning trajectory from an entry point on the patient to a target point within the patient. Using an imaging device, a first scan of the patient is performed to generate a first image volume data set of a first area of the patient. A first sectional image of the patient is displayed on a human-readable display device associated with the imaging device. The first sectional image is based on the first image volume data set. Using an operator interface device, a second planning image of the patient is defined by placing a plurality of graphical point symbols in the first sectional image of the patient displayed on the display device. The plurality of graphical point symbols define a second area of the patient to be subject of display as a second sectional image of the patient. The second sectional image of the patient is derived either directly from the first image volume data set, indirectly from the first image volume data set by interpolation, or by performing a second scan of the patient with the imaging device.

摘要： A method and system for using real time closed loop feedback to control the delivery of heat energy is disclosed herein. An energy delivery system may be used to deliver heat energy to a target to effect a change in the target. For example, medical professionals use laser energy to irreversibly damage cells found in cancerous tumors without damaging the surrounding healthy cells. The energy delivery system includes a temperature detection system, a data processor, and a heat generating device. The temperature detection system obtains temperature data from a target and transmits the data to the data processor. The data processor may process the temperature data to provide real time feedback control to the heat generating system, as well as display the data as one or more images on a graphical user interface. The heat generating system receives control commands from the data processor and modulates its heat output accordingly.

摘要： A system and method for delivering fractionally inspired oxygen (FiO2) to a patient in response to receiving an arterial hemoglobin oxygen saturation signal (SpO2) are disclosed. The SpO2 is measured, for example, by using a pulse oximeter. An algorithm receives a signal indicating the SpO2. The algorithm determines wither the SpO2 is in the normoxemia range, hypoxemia range or hyperoxemia range. The algorithm also determines trends by calculating a slope of second-to-second changes in the SpO2. Based on the current SpO2 and the trend, the algorithm determines the appropriate FiO2 for the patient and instructs a device, such as a mechanical ventilator or an air oxygen mixer as to the appropriate FiO2 to be delivered to the patient. The system initializes various parameters with default values, but a user (e.g., a nurse) can also update the settings at any time. The system also provides alerts for various conditions, for example, standard pulse oximeter alarms, as well as notification when an episode of hyperoxemia or hypoxemia occurs, when it lasts for more than a specified period of time (e.g., two minutes) in spite of FiO2 adjustments and when the adjustments set the FiO2 at certain levels. The user is also alerted when SpO2 signal is lost.
