In a blood pressure monitor, when a main unit is mounted on a mounting surface such as a desk, a bulging region of a first tube and a bulging region of a second tube, both located at a rear surface of the main unit, come into contact with the mounting surface. This can avoid the main unit from sliding even when the main unit is pulled by the first and second tubes. Consequently, a blood pressure monitor has a configuration in which the main unit is less likely to slide over the mounting surface even when the main unit is pulled by tubes connected to the main unit.

The medical data acquisition device includes a vibration source for emitting a vibration at a predetermined or random frequency. When the acquisition device is activated, a vibration is transmitted from the through the patient and is detected by the accelerometer. The accelerometer then measures the particular frequency of vibration and transmits this information to a centralized monitoring unit (CMU). Based on the measured frequency, the CMU is able to know that the same patient wearing/holding the device is also the same patient using the data acquisition device. The vibration source may revolve through a number of predetermined frequencies (as determined on its own or instructed via the CMU) or simply generate a random frequency.

Techniques are provided for detecting a clinically-significant pulmonary fluid accumulation within a patient using a pacemaker or other implantable medical device. Briefly, the device detects left atrial pressure (LAP) within the patient and tracks changes in the LAP values over time that are indicative of possible pulmonary fluid accumulation within the patient. The device determines whether the changes in LAP values are sufficiently elevated and prolonged to warrant clinical intervention using, e.g., a predictor model-based technique. If the fluid accumulation is clinically significant, the device then generates warning signals, records diagnostics, controls therapy and/or titrates diuretics. False positive detections of pulmonary edema due to transients in LAP are avoided with this technique. Pulmonary artery pressure (PAP)-based techniques are also described.

The present specification discloses systems and methods of patient monitoring in which multiple sensors are used to detect physiological parameters and the data from those sensors are correlated to determine if an alarm should, or should not, be issued, thereby resulting in more precise alarms and fewer false alarms. Electrocardiogram readings can be combined with invasive blood pressure, non-invasive blood pressure, and/or pulse oximetry measurements to provide a more accurate picture of pulse activity and patient respiration. In addition, the monitoring system can also use an accelerometer or heart valve auscultation to further improve accuracy.

Ambulatory physiological monitoring with remote analysis

Номер: US20120259233A1
Автор: Eric K. Y. Chan, Harold Strandquist
Принадлежит: Individual

Applicants have disclosed a wireless method for remotely monitoring the physiological status of ambulatory patients by using at least one “cloud” server. Physiological data, including ECG data, is collected by a device worn by a patient and then wirelessly transmitted (e.g., via a cell phone) to the server(s). Remote processing of electrocardiograms (“ECG”) is achieved, in part, by data streaming packet lengths acquired over no less than 3 seconds—3 seconds is typically equivalent to about 3 cardiac cycles (heartbeats)—to provide the quickest response time by clinicians to try to save a heart patient's life. Other types of physiological data are monitored by the device, so medical help can be obtained when needed. In this manner, any sudden onset of vicissitudes in a patient's well being may be detected and transmitted to the care-giver and patient in near real-time.

Imaging based interferometric pressure sensor

Номер: US20120277593A1
Автор: Demetri Psaltis, Wuzhou Song
Принадлежит: Ecole Polytechnique Federale de Lausanne EPFL

An imaging based interferometric pressure sensor apparatus compromise a fluid pressure sensor unit ( 1 ) and an optical monitor ( 2 ). The disposable pressure sensor part comprises a rigid transparent cover plate 3 and a flexible diaphragm ( 4 ), in between forming an air-gap cavity ( 8 ). By illuminating the air-gap cavity ( 8 ) with a light source ( 6 ), the air-gap cavity generates an interference pattern which is captured by the optical imaging device ( 7 ). The pressure of the fluid ( 5 ) to be sensing is applied to flexible diaphragm, causing the deformation of the diaphragm and the variation of the air-gap thickness. Hence the interference pattern varies with pressure of fluid. The optical monitor ( 2 ) includes light source 6 and optical image device ( 7 ) which records the interference pattern from the fluid pressure sensor unit ( 1 ). The pressure of the fluid is measured by processing the captured image.

A relation is formed between an n-tuple having n components and formed at a first point in time and at least one other n-tuple having n components formed at at least one corresponding later point in time, wherein n is a natural number equal to or greater than 1, and the components comprise at least one derived parameter and/or one read-in data value. If this relationship satisfies a predetermined calibration criterion, a calibration signal is triggered and is displayed, and/or automatically triggers a recalibration of the haemodynamic monitoring device. For example, the pulse contour cardiac output PCCO is derived from the arterial pressure curve as the constituent component of a 1-tuple. As long as this differs from the reference cardiac output CO Ref by less than a predefined threshold value, for example 101 or 15% of the reference cardiac output, parameter determination continues without initiating a new calibration. On the other hand, if the deviation exceeds PCCO-CO ref I, the calibration signal is triggered.
