摘要:
A method for measuring body fluid constituents and storing the test data, which stores the measurement data of body fluid constituents measured by means of a small-size, light-weight, portable analyzing apparatus and a solid reagent, in the memory circuit of the apparatus, and after the required or specified number of measurement data has been stored, delivers the data into an external device. The external action data can also be stored. A method of controlling and processing the test data of body fluid constituents which stores one lot of data groups of each apparatus in an external unit together with the data for identifying the patient and displays the measurements of each patient calculated from one or a plurality of data groups of each analyzing apparatus in digital or analog form.

A method and apparatus for quantitatively determining a degree of agglutination of a suspension of particles or the presence of the agglutination thereof is disclosed, wherein a liquid which contains agglutinated clots, otherwise a substance or substances to be about to agglutinate is made to slowly transfer through a small tube, in course of which agglutinated clots and non-agglutinated particles separate from each other in the liquid, when a degree of agglutination of particles and the concentration of the substance to be tested herewith can be determined quantitatively through the detection of difference in the optical properties of both the accumulation layer of agglutinated clots and the suspension layer of non-agglutinated particles, or the change in the optical properties of either of the above two layers, in particular the suspension layer.
摘要:
A method and device for measuring the osmotic pressure on the basis of an improved supercooling process, whereby and wherein cryohydrate nuclei are made to generate almost spontaneously in a part of a sample liquid by cooling the above part down further to a temperature (to an extra-supercooled state) lower than the temperature of a supercooled state, wherethrough the sample liquid as a whole is induced to freeze statically. Because of a non-necessity of using any stirring rod, it becomes possible to design a small-sized device, to reduce the sample liquid to be used to a possible infinitesimal, and further to perform the continuous measurement with the aid of the adoption of a flow cell.
摘要:
A reference scatterer for use in the correction of scattering type photometers having a reference glass scatterer main body with microcrystals therein to split the phase of incident light which is housed within a vessel with a clearance between the two. The clearance is filled with a liquid whose index of refraction substantially matches that of the main body.
摘要:
Disclosed is an analysis implement including a support and a reagent layer containing an oxidase applied to the support such that one surface of the reagent layer is exposed to an air atmosphere. A hydrophobic, porous, oxygen permeable layer is positioned between the reagent layer and the support, such that oxygen can permeate to the layer containing oxidase.
摘要:
An autonomous continuous analysis method and apparatus using Dip and Read type analytical implements. A series of operations of taking out analytical implements, dipping them in the sample solution, optical measurement, calculation, and disposal of the used sample solution are performed automatically.The dip stage, in particular, is automated by use of an analytical-implement automatic supply device and an analytical implement automatic handling device which, holding an analytical implement, dips it in the sample solution, and sets it ona reaction turntable. A number of analytical implements are put in a storage section comprising a bottom section provided with an analytical implement groove and at least one inside surface which is parallel with the groove, are taken out one by one by the relative movement of the groove and in normal and reverse direction and by stopping in a specified position after confirming by a detector that an implement has been caught in the groove.
摘要:
A method and apparatus are disclosed for an analyzer which measures concentration of a liquid specimen by monitoring the coloration of test paper which is either dipped into the specimen or is otherwise painted with it. In the method, inner stray rays produced by a light source which do not reach the test paper are experimentally monitored, so that the effect of such inner stray rays upon the accuracy of the test paper analysis is eliminated. Additionally, a method of relating relative reflectivity of the test paper to the concentration of the specimen is disclosed, in which method the calibration curve is modeled as a section of a hyperbola. In the apparatus, a microcomputer performs the evaluation and the detection of the coloration of the test paper and the compensation for various sources of instrumental error takes place electronically.

A composition and test piece or dipstick for measuring the glucose concentration in body fluids such as urine, spinal fluid and blood. The composition includes a glucose oxidase, a peroxidase a N,N'-tetramethyldiaminophenylmethane and guaiac.
摘要:
A number of blood samples collected in sample vessels are allowed to stand by as whole blood or blood cell layer, the sample vessels are sent into sampling part in order, the blood sample suctioned from the sampling nozzle is diluted by mixing with hemolyzing liquid containing labile HbA.sub.1c removing reagent, a part of the mixture is led to a sample-loop of sample injection valve and injected into the column of high pressure liquid chromatograph at a specified time after mixing start, hemoglobin fractions are measured in the state of removal or lowering of labile HbA.sub.1c, and the rate of stable glycohemoglobin is determined from thus obtained chromatogram.
摘要:
A portable type clinical examination device using expiratory air of a patient as a sample and measuring with high accuracy and rapidity concentration of trace amounts of aimed gas components contained in the expiratory air. The clinical examination device feeds an expiratory air sample provided by a patient, fed through an expiratory air sucking portion and separated in a column to a detector which detects trace amounts of aimed gas components contained in the expiratory air sample by ionizing the aimed gas components through application of ultraviolet or radiation, so that output signals from the detector are processed and concentration of the aimed gas components is computed by use of a previously memorized working curve to provide a clinical examination data which is output on a recording device or the like.
