Abstract

PROBLEM TO BE SOLVED: To improve correctness and preciseness of urine quantity and urine specific gravity measurement by providing an automatic control means for controlling a means for measuring the specific gravity and quantity of sampling urine. SOLUTION: When a urine cup 6 containing urine is set in an insertion window 5, a patient's name is automatically identified by a bar code reader 8, and the patient's name is displayed on a display window 22. When a start button is pressed, the cup 6 is inclined to pour urine into a urine funnel 3, and the weight is measured by a load cell 4. A valve 11 is opened to pour the urine into a fixed capacity injection cylinder 10, where the specific gravity of the sampling urine is computed, and the urine quantity (capacity) is measured. When a three-way valve 13 is shifted and connected to a 4% dispensing cylinder 12, 4% of urine is injected into the cylinder 12, and when the three-way valve 13 is shifted, the urine in the cylinder 12 flows into a sampling cassette 14. The valve 11 is then opened to discharge the urine in the cylinder 10 into a catch basin 15. A controller 24, a control part 26 and a CPU 27 constitute an automatic control means and controls the whole device.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for automatically measuring the specific gravity of urine volume, which is obtained by sampling a fixed ratio of urine volume as a specimen by a urine storage device which is the basis of medical diagnosis.

[0002]

2. Description of the Related Art At present, as a means for measuring urine volume and urine specific gravity in medical institutions such as hospitals and medical facilities, 24-hour urine is stored in a urine bottle instead of conventional manual handling by nurses and nurses. Method to automatically measure the total urine volume, and further reduce the burden on attendants and nurses, measure part of urine in consideration of odor, bacterial generation and contamination by processing means, and discard other urine. An automatic processing method has been implemented. However, there are some patients who need to stir and mix the whole urine for 24 hours as a patient for measurement by collecting part of urine. Therefore, an automatic measuring device has been developed which stores a required amount of urine, and there are a method of storing all urine and a device for collecting only a part of the urine. As a prior application, Japanese Patent Application No. 7-282588 (JP-A-9-101251) has been proposed.

[0003] However, the dispensing method is a means for collecting a fixed amount relative to the total amount of urine collected, and the measuring device quantitatively collects a part of the entire urine. In spite of the difference, since the amount of urine collected is almost the same for all patients, the accuracy and density differ depending on the collected urine, and there is a difference in the specific gravity of urine. In other words,
The same specific gravity needs to be measured regardless of the urine volume of any part of the total urine in one day. For example, when urine is sleeping or during daytime activities, or when taking diuretics, urinary output and specific urinary components are different, so a method of collecting only a certain amount and analyzing urine is the same as when urine comes out in large quantities In the case of a small amount of urine, the case of collecting a fixed amount is treated in the same way, so that it does not represent the average value over 24 hours, and there may be cases where effective sample results cannot be obtained for the measurement contents of urine specific gravity Becomes Therefore, in the urine specific gravity measurement of the prior application, the quantitative partial urine collecting apparatus lacks specificity and accuracy in determining the specimen data when performing a medical examination because a specific gravity difference occurs in the measurement as urine analysis of the same patient. There are difficulties.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned difficulties, and it has been proposed to improve a urine specific gravity measuring means which is collected as a sample by a quantitative formula, and to collect urine in a urine collection funnel. The main object of the present invention is to obtain a urine volume specific gravity measurement with accuracy and precision by using a method apparatus for collecting a urine volume of a fixed ratio of the total amount as a specimen.

[0005]

Means for achieving the above object include a urine collecting funnel, a load cell below the funnel, and a urine sampling device for sampling a fixed ratio of urine volume at a set temperature collected in the funnel. And means for measuring the specific gravity and urine volume of the sampled urine put into the device,
A means for storing the measured partial urine in a cassette, a processing means for cleaning the means and discharging the same by an actuator, and a method for automatically measuring the specific gravity of urine volume by controlling each of the means by a controller. A body device incorporating the automatic control means, a display unit for identifying a patient,
A bar code reader, a washing tank for automatically washing a urine collection cup, and a urine storage device provided with a urine collection cup entrance and a sampling cassette outlet to the washing tank after collecting urine of a certain percentage of patients collected by an actuator as a specimen. It is an object of the present invention to provide an automatic urine specific gravity measuring method and an automatic control device for collecting a fixed ratio of urine as a specimen.

In this case, the diameter of the urine collection funnel 3 and the inner diameter of the sample dispensing cylinder 12 are designed to have a fixed ratio, and the sample dispensing cylinder 12 is used in accordance with the amount of urine collected in the urine collection funnel 3.
The device is designed so that urine at a certain ratio is collected. Next, the urine collected in the dispensing cylinder 12 is opened as a urine test into the sampling cassette 14 by opening the three-way valve 13. Numeral 16 denotes an actuator which is mounted so as to move to the sampling cassette and the urine (water) pipe side. Excess urine from the urine collection funnel 3 after a certain percentage, for example, 4% of urine is collected, is discarded from the discharge basin 15 by the drain pipe 17.

Next, an example of use of the urine volume urine specific gravity device of the present invention will be described. The patient automatically sets a bar code reader 8 by setting a urine cup from which urine is collected in the cup insertion window 5 of the device.

Press (start button). The cup 6 is tilted and poured into the urine collecting funnel in the vessel. As an automatic control action of the in-vessel device, when the urine is completely collected in the urine collection funnel 3, the weight is measured by the load cell 4. Since the urine collection funnel is provided in a floating state in the urine storage device 2, the weight of the valve 11 is

An air vent valve 28 is provided on the valve 11 and the cylinder 10 so that the air can easily flow and no air bubbles are generated. When the urine completely enters the constant volume injection cylinder 10, the urine in the funnel is measured again by the load cell 4. The specific gravity of the urine is calculated from the weight of the urine that has entered the constant volume injection cylinder 10. By multiplying the initial urine weight by the specific gravity value, the amount (volume) of urine is measured. When the three-way valve 13 is switched and connected to, for example, a 4% dispensing cylinder 12, urine is
