A blood rheology measurement device measures a blood rheology of blood flowing through an artery inside of a living body from outside of the living body. The blood rheology measurement device has a sensor that detects a flow rate of blood flowing through the artery and a pulsatile displacement that varies with an elapse of time. The pulsatile displacement corresponds to a displacement of the artery in a diameter direction thereof due to expansion and contraction of the artery resulting from a pulsatile motion of the heart. A calculating section calculates the blood rheology of blood flowing through the artery on the basis of the blood flow rate and the pulsatile displacement detected by the sensor.

Systems and methods are described herein to evaluate a candidate medication as it relates to a subject's cardiovascular health. A processing component is employed to measure a first value of one or more cardiovascular markers, via a computer, which are associated with a circulatory system of each subject that is to receive the candidate medication. The candidate medication is administered to each subject and a second value of one or more cardiovascular markers are measured subsequent to the administration as of the candidate medication. Continued testing of the candidate medication can be continued dependent upon the change in the one or more cardiovascular markers.

A replaceable magazine for use in an analytic test instrument a plurality of analytic aids on a carrier tape. The analytic aids can be made available in an application position of the magazine by means of the carrier tape. The magazine has a supply reel for holding regions of the carrier tape with unused analytic aids and a take-up reel for holding regions of the carrier tape with used-up analytic aids. The carrier tape can be moved in a spooling direction from the supply reel to the take-up reel. The magazine has a rewind lock of the take-up reel. The magazine has a tape release device, which is configured to make available a take-up reel tape reserve of the carrier tape on the side of the application position facing the take-up reel. The take-up reel tape reserve enables a lifting movement of an analytic aid situated in the application position.

The present invention relates, in general, to lancing elements for use in drawing bodily fluids out of a patient and, more particularly, to an improved lancing element including first and second elements positioned relative to each other such that an incision formed by the first element is held open by the second element and bodily fluids are pulled up the lancing element by surface tension on the first and second lancing elements.
摘要:
A method for determining the viscosity of a fluid flowing through a system at any point in the system whereby the method involves determining a characteristic relationship for the fluid between viscosity and shear rate; obtaining a shear rate of the fluid as it moves through at least one position in the system; and determining the viscosity of fluid at the at least one position by applying the shear rate to the characteristic relationship. Where the system is the circulatory system of a living being, the method includes determining a viscosity-shear rate relationship unique to that individual. Furthermore, the method further entails determining the actual viscosities and shear rates being experienced in selected blood vessels of the living being.
摘要:
A scanning rheometer is presented for the rheological property measurement of electrorheological (ER) and magnetorheological (MR) fluids using a non-linear viscoplastic model, based on the fluid height variation with respect to time. The rheometer basically includes a static (e.g., an overhead reservoir) or a dynamic source of fluid, a channel or slit whose sides form electrodes which are in contact with the flowing ER fluid, or a capillary tube exposed to a static/alternating magnetic field for flowing MR fluids, a transfer tube, either one or two riser tubes, and a column level detector for monitoring the column of fluid as it moves in one of the riser tubes. The column level detector is coupled to a processor which analyzes, among other things, column height vs. time data to determine both viscosity and yield stress. The rheometer overcomes one of the major drawbacks of the conventional rheometer: the inability to produce the yield stress of the ER, or MR, fluid in an absolute zero shear rate range. The results with this rheometer are compared with those obtained from a commercially-available rheometer which indicates excellent agreement.
