Abstract: A method and apparatus for measuring a dynamic flow rate of a bodily fluid in which the rate of flow is constantly changing includes an inlet to a chamber where flow accumulates. The accumulating fluid is in communication with the base of a sealed vertical column of air. An air pressure transducer in the upper portion of the column of air measures the pressure exerted upon the air by the accumulated fluid. The air pressure corresponds to the volume of accumulated fluid and is manipulated to yield a running indication of the flow rate. The chamber is automatically drained by a drainage conduit when the fluid reaches an upper operating level to reset the apparatus to a lower operating level to be ready to resume taking meaurements.

Abstract: A urine discharge measuring system for medical use which includes a gimbal mounted frame supporting a urine container of fixed dimensions to collect urine from a urinary catheter attached to a patient. An ultrasonic transceiver mounted above the container and operated in conjunction with a microprocessor based control unit, positioned adjacent to the transceiver, periodically and automatically measures the height of the urine collected within the container. The measured fluid height is converted to fluid volume by the control unit. To maintain the sterility of the container, the transceiver transducer(s) is mechanically isolated from the urine container by elements which allow the ultrasonic energy to be transmitted to and received from the interior of the container. In one described embodiment, desired measured volume accuracy is achieved by employing a reflective target within the urine container at a known fixed distance from the transceiver transducer. Comparison by the control unit of the measured distance with the actual distance to the target allows generation of corrections for variations of the speed of sound in air due to temperature and humidity to be applied when obtaining the urine height within the container. Digital displays in the control unit provide indication of past and present accumulation of the urinary output of the patient.
Abstract translation: 一种用于医疗用途的排尿测量系统，其包括支撑固定尺寸的尿液容器的万向架安装框架，用于从附接到患者的导尿管收集尿液。 安装在容器上方并与位于收发器相邻的基于微处理器的控制单元操作的超声波收发器周期性地并且自动地测量在容器内收集的尿液的高度。 测量的流体高度由控制单元转换成流体体积。 为了保持容器的无菌性，收发器换能器通过允许超声波能量传递到容器内部并从容器的内部接收的元件与尿液容器机械隔离。 在一个所描述的实施例中，通过在距离收发器换能器已知固定距离的尿容器内采用反射目标来实现期望的测量体积精度。 通过控制单元将测量距离与到目标的实际距离进行比较，可以在获得容器内的尿液高度时产生由于温度和湿度导致的空气中的声音速度的变化的校正。 控制单元中的数字显示器提供患者的尿路输出的过去和现在积累的指示。

Abstract: A counter counts the time intervals of falling instilled drops in response to a signal issued each time a falling instilled drop is detected. A memory is supplied with data representing the quantities of a falling instilled drop corresponding to the time intervals at which the drops fall. The data corresponding to the time intervals thereof which have been counted by the counter are read out of the memory. The data thus read out are accumulated to determine the total quantities of the drops.

Abstract: A system with an analyzer device in fluid communication with a sample of a bodily fluid is configured to chemically or electrochemically convert at least a portion of ammonium (NH4+) contained within the bodily fluid into ammonia (NH3) and dispel the converted ammonia (NH3) into a gas sensing chamber. An ammonia (NH3) sensor located within the gas sensing chamber in conjunction with a processor can quantify an amount of ammonia (NH3) present in the gas sensing chamber in relation to the total ammonia of the bodily fluid.

Abstract: A measurement probe includes: an elongated body that is insertable into a catheter having a flow path; a sensor fixed to the elongated body and capable of detecting a state of a fluid flowing in the flow path; and a sensor holding portion that holds the sensor at a predetermined position when the elongated body is inserted into the catheter. An output of the sensor changes depending on an oxygen partial pressure in the fluid, a carbon dioxide partial pressure in the fluid, a hydrogen ion index of the fluid, an amount of potassium ions in the fluid, an amount of sodium ions in the fluid, an amount of chlorine ions in the fluid, a temperature of the fluid, or a flow rate of the fluid.

Abstract: Devices, systems, and methods for planning radiosurgical treatments for neuromodulating a portion of the renovascular system may be used to plan radiosurgical neuromodulation treatments for conditions or disease associated with elevated central sympathetic drive. The renal nerves may be located and targeted at the level of the ganglion and/or at postganglionic positions, as well as preganglionic positions. Target regions include the renal plexus, celiac ganglion, the superior mesenteric ganglion, the aorticorenal ganglion and the aortic plexus. Planning of radiosurgical treatments will optionally employ a graphical representation of a blood/tissue interface adjacent these targets.

Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.

Abstract: A method of mapping autoregulation of a kidney using magnetic resonance (MR) imaging is provided. The method includes acquiring a time series of MR images of a subject while the subject is at rest by acquiring MR images of an imaging region repeatedly over a period of time by applying a pulse sequence. The imaging region includes at least a kidney of the subject. The method also includes analyzing the time series of MR images along a temporal dimension, and identifying features associated with autoregulation of the kidney including tubuloglomerular feedback (TGF) in voxels of the MR images based on the analysis. The method further includes generating a map and/or a metric of the autoregulation based on the identified features, and outputting the map and/or the metric.
