A finger wearable device for monitoring vital signs at a finger includes a housing, a finger cuff, a plurality of vital sign sensors, and an electrocardiogram (ECG) sensor. The housing includes an interface surface for pressing against the finger. The finger cuff attaches to the housing and has a size and a shape to secure the housing to the finger and force the interface surface against the finger when the finger cuff is worn around the finger. The vital sign sensors are disposed in or on the housing and orientated to measure the vital signs from the finger of a wearer. The ECG sensor is disposed in or on the housing and coupled to first and second electrodes to measure ECG signals. The second electrode is disposed on the interface surface.

System for determining real-world effectiveness of various prescribed medications. Here a variety of different types of patient pulse wave measurements (e.g. blood pressure, pulse oximeter, ECG) and other physiological measurements are obtained. This actual data is compared to calculated measurements that would be expected based on the various patient baseline measurements in the absence of medication, schedule of medications, and impact of medications the various patient baseline measurements. If the actual data meets expectations, then the medication is likely acting as anticipated. Depending on which types of data do not meet expectations, problems with one or more previously described medications may be reported. Other types of patient physiological readings, such as temperature, motion, lung function, brain wave function (EEG) and the like may also be obtained, and these additional types of readings can be used to extend the range of different types of drugs/medications that the system can successfully monitor.

The present invention provides a system for measurement of blood pressure by detecting the Korotkoff sound. The system comprises an arm band placed on the brachial artery of the user and pressure is applied to the artery by inflating the cuff through an inflation pump provided in a measurement unit, thereby forcing the artery to close. Further, the pressure is reduced by opening at least one valve and by reducing the pressure the Korotkoff sounds are detected using the ausculatory blood pressure monitoring component placed in pneumatic pathway of cuff. The acoustic sound is detected in the audible range of 20 Hz to 10 KHz and also ultrasonic range between 60 KHz to 80 Khz. In this range the signal to noise ratio is maximal. The method for detecting the blood pressure through the present system enhances acoustic signal detection that improves blood pressure measurement accuracy.

A charging station for providing power to a physiological monitoring device can include a charging bay and a tray. The charging bay can include a charging port configured to receive power from a power source. The tray can be positioned within and movably mounted relative to the charging bay. The tray can be further configured to secure the physiological monitoring device and move between a first position and a second position. In the first position, the tray can be spaced away from the charging port, and, in the second position, the tray can be positioned proximate the charging port, thereby allowing the physiological monitoring device to electrically connect to the charging port.

Various systems and methods for collecting patient data are discussed herein. According to some systems and methods, a timer may be started, and a blood pressure data collection system is actuated to obtain a blood pressure measurement of a patient upon the expiration of the timer. The timer may be incorporated into a patient data collection system or method to ensure the patient is relaxed and calm prior to taking a blood pressure measurement. An event may be sensed by an environmental sensor system and the timer may be started in response to sensing the event. A clinician leaving a room where the patient is disposed is one example of an event. An interruption may be sensed by the environmental sensor system and the timer may be terminated in response to sensing the interruption. The clinician entering the room where the patient is disposed in one example of an interruption.

Blood pressure detection apparatuses and methods for detecting a blood pressure of a user are described comprising optical sensors/detectors and a force sensor and, in some embodiments, comprising only a force sensor, measuring force applied by a finger. Blood pressure is measured by applying an increasing (or decreasing) force or pressure with a finger of the user on at least the force sensor, which, in some embodiments, may be a plurality of increasing pressure steps, each step being held within a predetermined acceptable pressure/force tolerance range for a predetermined hold time, and measuring the force applied by the finger and, in some embodiments, optically measuring the blood in a vessel in the finger relating to the applied pressure/force. Feedback (visual, haptic, sound) of the applied pressure is provided to the user.

An assembly for enabling a caregiver to secure a physiological monitoring device to an arm of a user can include the physiological monitoring device a cradle configured to removably secure to the physiological monitoring device and to the user's arm. The physiological monitoring device can include a first connector port configured to electrically connect to a first cable and a first locking tab movable between an extended position and a retracted position. The cradle can include a base, first and second sidewalls, a back wall connected to the base and the first and second sidewalls. The cradle can further include a first opening in the back wall configured to receive the first connector port and a second opening in the first sidewall configured to receive the first locking tab when the physiological monitoring device is secured to the cradle and the first locking tab is in the extended position.

The air circuit box comprises a shell with a cavity formed inside. The shell is provided with an access port, an air charging port and an air inlet port spaced apart, and the access port, the air charging port and the air inlet port are all connected to the cavity.

Single- or dual-bladder devices for automated delivery of remote ischemic conditioning treatment via partial limb occlusion involve various methods of operating the cuff in which partial or full limb occlusion is achieved during the periods of cuff inflation. Achieving clinical benefits of remote ischemic conditioning without extended cessation of limb blood flow are advantageous due to lower required cuff pressure and reduced risk of clot formation in the limb vasculature.

A blood pressure measuring auxiliary device, a blood pressure measuring apparatus and a design method therefor are provided. During a blood pressure measurement, the measured pressure values and beating sound are recorded, so that the recorded pressure values and sound may be played back, which improves the accuracy of the auscultatory method; and the parameters used in the oscillometric method may be adjusted, which improves the accuracy of the oscillometric method. The blood pressure measuring auxiliary device is arranged so that it can be connected with a pressuring device of a sphygmomanometer (5), and comprises a sensing module (1), a communication module, and an audio collection module (2). The sensing module (1) is used for sensing the pressure at the joint between the blood pressure measuring auxiliary device and the pressuring device and outputting a pressure signal to the communication module. The communication module is used for receiving the pressure signal to be transmitted thereby to a terminal apparatus (6). The audio collection module (2) is used for collecting the sound at a measured site and outputting an audio signal to the terminal apparatus (6).
