SPECIFIC GRAVITY MEASURING APPARATUS FOR SAMPLED URINE ACCUMULATION

摘要

PURPOSE:To make working simple as well as sanitary, by feeding urine into a measuring cylinder each time it is discharged to permit the detection of specific gravity and amount thereof with a float, a liquid surface sensor, a temperature sensor and a floating difference sensor. CONSTITUTION:One batch of urine being discharged is put into a sample feeding port 2 and made to flow into a measuring cylinder 11. When the urine in the cylinder 11 fills the whole of a constant capacity chamber 11a, this condition is detected with a liquid surface sensor 13 and a temperature sensor 14 detects the temperature of the urine while a floating difference detection sensor 15 detects the level of a float 12. Detection signals from the sensors 13-15 are inputted into a computer built into the apparatus and specific gravity of the urine is computed and stored to be shown on a display device 5. Thereafter, when the total amount of the urine is sent into the cylinder 11, the condition is detected with a residue detection sensor 25 and the final level of the float 12 is detected with the sensor 15. Then, detection signals from the sensors 15 and 25 are inputted into the computer and the total amount of one batch of urine being discharged is computed and stored to be shown on the display device 5.
