Abstract

PURPOSE:To prevent the adhesion of urine to a sensor and to enhance accuracy by subjecting a clamper and a cover to opening and closing operation in connection with the advance and retraction movement of a sensor unit. CONSTITUTION:A test piece 6 is inserted in a holder 25 and a cover 2a is closed while a motor is driven to allow a slider 22 to fall and the lower end of the test piece 6 is immersed in an urine sump part. Subsequently, the motor is reversed to raise the test piece 6 to the position of an urine data analyser. Thereafter, a motor 46 is driven to allow a sensor unit 47 to advance along with a moving body 48. Whereupon, the sensor head 50 of the unit 41 is fitted in the recessed part 58 of a clamper 42 to push the clamper 42 forwardly along a guide hole 54 and the cover 43 supported by the clamper 42 also moves forwardly. Herein, since the cover 43 is turned to the front of the test piece 6 gradually with the advance of the unit 41, because a roller 57 is in contact with a can surface 56, to hold the test piece 6 between the cover 43 and the clamper 42. In this state, a constant gap is formed between the front surface of the head 50 and the test piece 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for analyzing components such as glucose in urine.

(Prior art) Japanese Patent Application Laid-Open No. 1983-1988 (Kokai) published a toilet bowl incorporating a urine data analyzer in order to prevent adult diseases by analyzing components in urine when defecating.
It is known as No. 53161.

The analyzer installed in such a toilet bowl lowers a test piece to the urine pool formed in the bowl of the toilet bowl, deposits urine on the lower end of the test piece impregnated with a reagent, and then pulls the test piece upward to remove the urine. By irradiating light onto areas that have reacted and changed color due to adhesion, and detecting the amount of reflected light with a sensor, it is possible to determine the proportion of specific components in the urine, such as glucose, urobilinogen, protein, or occult blood. .

(Problems to be Solved by the Invention) According to the urine analyzer described above, since the test piece is pulled up close to the sensor for analysis, there is a risk that the test piece will move and urine will adhere to the sensor. Considering that the accuracy decreases dramatically when moisture adheres to the test piece, the sensor must be placed a certain distance from the test piece even if the accuracy decreases a little.

Furthermore, in order to measure the amount of light reflected from a discolored portion of a test piece, it must be carried out in a light-shielded space, but conventional methods do not have a structure that can sufficiently shield light.

(Means for Solving the Problems) In order to solve the above problems, the first invention of the present application includes a clamper and a cover that clamp a test piece, and a sensor unit that includes a clamper and a cover that clamp a test piece, and a light emitting element and a light receiving element. The clamper and the cover are configured to open and close in conjunction with the forward and backward movement of the sensor unit, and the second invention includes a sensor unit that houses the sensor and a test piece in the main part of the urine data analyzer. The sensor unit and table are combined to form a dark box.

(Function) In the first invention, the sensor unit is closest to the test piece with the test piece positioned and fixed by the clamper and the cover, so there is no risk of urine adhering to the sensor. Furthermore, since the forward and backward movements of the sensor unit are linked to the opening and closing operations of the clamper and cover, only one driving source such as a motor is required.

Furthermore, in the second aspect of the invention, the table on which the test piece is placed constitutes a part of the dark box, which simplifies the structure.
