182 results about "Secondary analysis" patented technology

Secondary analysis is the practice of using secondary data in research. As a research method, it saves both time and money and avoids unnecessary duplication of research effort. Secondary analysis is usually contrasted with primary analysis, which is the analysis of primary data independently collected by a researcher.

Detection of Drastic Blood Pressure Changes

InactiveUS20080319332A1Rapid blood pressureReliable markerElectrocardiographyMedical automated diagnosisBlood treatmentsEvent type
The invention relates to cardiac-activity based prediction of a rapid drop in a patient's blood pressure during extracorporeal blood treatment. A proposed alarm apparatus (100) includes a primary beat morphology analysis unit (120), a bank of secondary analysis units (B2) and an alarm generating unit (158). The primary beat morphology analysis unit (120) discriminates heart beats in a received basic electrocardiogram signal (HECG), classifies each beat into one out of at least two different beat categories, and associates each segment of the signal (HECG) with relevant event-type data. The event-type data and the basic electrocardiogram signal (HECG) together form an enhanced electrocardiogram signal (ECGCL), based upon which the primary beat morphology analysis unit (120) determines whether one or more secondary signal analyses should be performed. Depending on the enhanced electrocardiogram signal's (ECGCL) properties, the bank of secondary analysis units (B2) performs none, one or more of up to at least two different types of secondary analyses, and for each analysis performed produces a respective test signal (PHRV, PEBC, PHRT)—The alarm generating unit (158) receives the test signals (PHRV, PEBC, PHRT), and triggers an alarm signal (α) indicative of an estimated rapid blood pressure decrease, if at least one alarm criterion is fulfilled.

The invention discloses an instrument-free quantitative analysis method for fast detecting test paper, and application of the instrument-free quantitative analysis method. A target analyte or a secondary analyte in a sample can react with a detection reagent to generate insoluble deposits to enhance the hydrophobicity of a reaction area, and the concentration of the analyte is in direct proportion to the enhancement degree of the hydrophobicity of the reaction area; the hydrophobicity of the reaction area decides the volume of a colored hydrophilic reagent solution flowing into a quantification area from the reaction area within set time or in a set distance (such as from the tail end of the reaction area to the quantification area), and the length of colored print in the quantification area is in direct proportion to the volume of the colored reagent solution flowing into the quantification area and is in inverse proportion to the hydrophobicity of the reaction area. Therefore, the concentration of the analyte in the sample is in inverse proportion to the length of the colored print in the quantification area, and the fast quantitative detection of the analyte in the sample can be carried out by measuring the length of the colored print in the quantification area through a ruler with scales. The method can be applied to quantitative detection on target analytes in various liquid samples of urine, blood, serum, saliva, water, etc.
