A hemodynamic parameter (Hdp) monitoring system for diagnosing a health condition of a patient and for establishing Hdp marker values or Hdp surrogate marker values for purposes of comparison with Hdp values of a patient is provided. An Hdp monitor senses, measures, and records Hdp values exhibited by the patient during a basal or non-exposure period and furthermore Hdp values exhibited by the patient during or after an exposure period during which the patient is exposed to low-energy electromagnetic output signals. An electrically-powered generator is adapted to be actuated to generate said low-energy electromagnetic carrier output signals for exposing or applying to the patient such output signals during said exposure period.

A sphygmomanometer according to the present invention includes a blood pressure measuring cuff worn around a site to be measured, a pressure device that pressurizes or depressurizes the cuff, and a sound detection device that detects a sound generated by the site to be measured via the cuff. An amplification factor setting unit measures a first passage time required for the pressure of the cuff to pass through a first pressure range in a pressurization process of the cuff, and variably sets an amplification factor for a Korotkoff sound component according to the first passage time. A blood pressure calculation unit receives an output of the sound detection device according to the sound from the cuff, amplifies the Korotkoff sound component included in the output at a set amplification factor, and calculates a blood pressure of the site to be measured.

A dry electrode and a physiological multi-parameter monitoring equipment are disclosed. The waterproof dry electrode comprises an encapsulation, extraction electrode and a contact surface layer, wherein the extraction electrode and the contact surface layer are connected with each other and disposed in the encapsulation; the contact surface layer comprises an exposed part and an embedded part encapsulation; the encapsulation comprises flexible silica gel and hard plastic portion, the embedded part being embedded into the hard plastic portion, and the hard plastic portion being packaged in the flexible silica gel. Through the above arrangement in the present invention, the dry electrode can reach a waterproof grade of IPX7, which is higher than living waterproof grade of an ordinary dry electrode. The PMPME can be a patch-type acquisition and monitoring equipment which is convenient for long time wearing and physiological multi-parameter monitoring, with excellent sealing and waterproofness, and the electrode is reusable.

A sphygmomanometer of the present invention includes a bag-shaped sensing cuff to be worn to wrap a measurement site, a back plate disposed on the sensing cuff along a surface opposite to the measurement site, a pressing member for pressing the back plate toward the measurement site, and a blood-pressure calculating part calculating a blood pressure based on a pressure of a fluid stored in the sensing cuff. Regarding a longitudinal direction perpendicular to a circumferential direction of the measurement site to be wrapped by the sensing cuff, a dimension of the back plate in a width direction along the longitudinal direction is larger than a dimension of the sensing cuff in the width direction.

In some embodiments, a self-monitoring intravenous catheter system is provided. An alarm controller is provided that receives signals representing a pH value, an oxygen saturation value, and a pressure value in proximity to the distal end of the catheter. By performing a fuzzy logic analysis of the values, the alarm controller is able to detect that the catheter is about to fail or has failed, and can cause alerts to be presented. In some embodiments, an intravenous catheter is provided that has a pH sensor and an oximeter disposed at a distal end of the catheter to obtain the pH value and oxygen saturation values analyzed by the alarm controller. Embodiments of the catheter and self-monitoring intravenous catheter system may be particularly useful in treating neonates, who are sensitive to catheter failure and are not capable of detecting the signs of failure themselves.
