A component measuring apparatus is provided with a case having a cylindrical case main body and a cover arranged to cover the base end opening section of the case main body; a chip mounting section for mounting a chip; a light measuring section for detecting a prescribed component; a printed board whereupon a control section having a function of controlling the operation of the light measuring section is arranged; a liquid crystal display device; a battery arranging section for arranging a battery provided on the cover; an O-ring arranged between the case main body and the light measuring section on the leading end section of the case main body; and an O-ring arranged between the case main body and the cover on the base end opening section of the case main body. Sealing of inside the case is ensured by the O-ring.

Component measuring apparatus

A tube connecting apparatus for grasping and heating to melt and alternately connect the cut ends of a plurality of tubes is disclosed. A first tube holder and a second tube holder for grasping the tubes are provided with a pair of clamps having holding portions for holding a plurality of tubes; each of the pair of clamps being moved into contact with, and away from, each other. One or both of the holding portions of the first tube holder and the second tube holder are formed of semi-circular separatable members and having a symmetry of rotation in relation to the center of the rotating axis, and have a grasping means for moving into contact with, and away from, the pair of clamps and have a rotating means for rotating the semi-circular holding portions of one or both of the first tube holder and the second tube holder.

Tube connecting apparatus

A measuring apparatus of the present invention measures the constituent concentration of a specimen after loading into the apparatus a test piece having a test material which develops coloring as a result of a reaction with the constituents of a specimen. When the apparatus detects that the test piece having the test material has been loaded, it automatically begins to measure the constituent concentration of the specimen. That is, after the loading of the test piece is detected, a predetermined time period is measured. During this time measurement, the time period is displayed at a predetermined time interval. After the time measurement of this predetermined time period is terminated, the test material is irradiated with a light, and the intensity of the light from the test material is detected. The constituent concentration of the specimen applied to the test material can be determined on the basis of the reflected light intensity thus detected. Furthermore, this measuring apparatus can detect a reverse insertion of a test piece, and is constructed so as to disable the measurement of the constituent concentration of a specimen if supplementary information to be stored along with measurement information has not been set.

Measuring apparatus

The present invention is an apparatus for measuring the constituent concentration of a specimen on the basis of the color change in a test material housed in a test piece, which has reacted because of the specimen. The apparatus irradiates the test material which is a test piece loaded in the apparatus's main body and detects the intensity of the light reflected by the test material. A detection signal detected in the above way is sampled in a time period before and after the measurement timing at which the test material changes in color because of the specimen. An average value of the sampled detection signals is determined. The constituent concentration of the specimen is computed by referring to a stored conversion table on the basis of the average value determined in the above way.
