摘要： The invention relates to a light-emitting apparatus (100) comprising an optical waveguide, particularly an optical fiber (1), for guiding a primary light beam (Bprim) into a light-splitting unit (101) which splits it into two or more partial light beams (Bl, B3, B4) which are emitted in different directions and have different optical qualities, e.g. different spectral compositions or polarizations. The apparatus may optionally comprise a detector (4) for determining a Doppler shift (Δλi) in reflected light reentering the light-splitting unit (101). This renders it possible to measure simultaneously two or more spatially independent vector components of the flow velocity of a fluid, particularly of blood, surrounding the light-splitting unit (101).

摘要： An apparatus for determining an initial flow rate (Q) of a liquid in a conduit (10), comprising:
(a) a means (20, 22, 70, 90) for introducing a change of a known volume of liquid over a known time to the initial flow rate (Q);
(b) a sensor (50, 50', 50", 72, 92) located downstream from the point for where a known liquid volume over a known time is introduced, the sensor (50, 50', 50", 72, 92) measuring a flow corresponding parameter; and
(c) a controller (100) connected to the sensor (50, 50', 50", 72, 92), the controller (100) being configured to determine the initial flow rate (Q) in response to the relative change (Cd) in the flow corresponding parameter downstream from where the flow is changed and the introduced known liquid volume over a known time, corresponding to Q = Q i C d ,
where Cd = ΔQd/Qd is the relative change in the measured flow corresponding parameter.

摘要： A device and method for assessing the degree of systemic perfusion in a patient. The system includes a surface perfusion pressure monitor (E) and a blood pressure monitor (C). The surface perfusion pressure monitor (E) may include laser Doppler sensor or a photoplethysmograph. A surface perfusion pressure index, or alternatively, an optical plethysmography index is derived from the surface perfusion pressure measurement and the blood pressure measurement to allow for assessment of systemic perfusion failure.

摘要： The present invention provides a coronary artery load detection system and method, and the method includes: (S1) obtaining the cross-sectional area of a reference cavity, and separately obtaining voltage values of a primary device at a location corresponding to the cross-sectional area of the reference cavity in a low frequency state and a high frequency state; (S2) separately obtaining voltage values of the primary device at the location of a bottom end or a top end of a to-be-detected object in the low frequency state and the high frequency state under the same current; (S3) driving the primary device to move at a constant speed, and obtaining a voltage value of the primary device during the movement in the low frequency state under the same current; and (S4) obtaining the cross-sectional area of each location of the to-be-detected object according to a preset fixed current value, the cross-sectional area of the cavity, and the obtained voltage values. According to the present invention, a voltage value of each location of the to-be-detected object is obtained in a frequency conversion mode, so that the sectional area of each location of the to-be-detected object is obtained by means of parsing; and parameters such as a plaque parameter and an FFR of each location of the to-be-detected object are obtained according to the sectional area, thereby greatly simplifying an operation and processing process and reducing the detection costs.
