SUMMARY OF THE INVENTION
In any of the urine measuring devices of D, since the urine input tank and the measuring tube are separated, there are the following problems. It takes time for the urine charged in the urine input tank to accumulate in the measuring tube, and the measuring time is long. The dirt easily adheres to the liquid sending tube and the connection part connecting the urine input tank and the measuring tube, and the dirt once adhered is hard to remove even after washing. The space occupied by the urine input tank and the measuring tube in the apparatus is large, and the apparatus becomes large and small, so that the measuring capacity is limited.

The above liquid level detection methods A to D have the following problems a to d, respectively. a) In the liquid level detection method A, the measuring pipe must be transparent, and if the measuring pipe is contaminated, the liquid level may not be detected due to a malfunction of the photoelectric switch. or,
When bubbles or bubbles are present in urine in the measuring tube, the photoelectric switch may malfunction due to the influence of the bubbles or bubbles, which may adversely affect measurement accuracy. Further, since the liquid surface is searched by driving the pulse motor, it takes a long time for the measurement. b) In the liquid level detection method B, measurement takes time because the float switch is moved by driving the pulse motor to search for the liquid level. c) In the liquid level detection method C, measurement becomes impossible if the detection surface of the ultrasonic sensor is contaminated. Further, when the urine volume is small, the distance between the detection surface of the ultrasonic sensor and the liquid surface is short, so that it is difficult to ensure the measurement accuracy. Further, since it is necessary to perform correction using the measured value of the specific gravity of urine and the measured value of urine temperature, a temperature measurement circuit is required, and the calculation algorithm becomes complicated. In addition, when the specific gravity measuring means cannot measure for any reason, accurate urine volume measurement cannot be performed. d) In the liquid level detection method D, since there is a temperature difference between urine and the device, dew condensation adheres to the detection surface of the pressure sensor, and the pressure sensor corrodes over time, making measurement impossible. In addition, when the urine volume is small, the head pressure becomes very small and the output level of the pressure sensor also becomes small, so that it is difficult to ensure the measurement accuracy. Further, since it is necessary to perform correction using the measured value of the specific gravity of urine and the measured value of urine temperature, a temperature measurement circuit is required, and the calculation algorithm becomes complicated. In addition, when the specific gravity measuring means cannot measure for any reason, accurate urine volume measurement cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems.
It is an object of the present invention to provide a urine measuring device which realizes a small size with a sufficient measuring capacity, stable operation, accurate urine volume measurement not influenced by the amount of urine, and a simple structure.

And a measuring unit, wherein the measuring unit is provided in a urine input tank. In this urine measuring device,
When the urine has been poured into the urine input tank, the urine volume is immediately measured by the measuring unit without being sent from the urine input tank to another portion (such as a measuring tube). That is, the urine measuring device of the present invention
Unlike a conventional device that guides urine in a urine input tank to a separately arranged measurement tube by a liquid feed tube or the like, the measurement unit itself is provided in the urine input tank. This eliminates the need for a measuring tube or a means for detecting the level of urine attached to the measuring tube, shortening the measuring time,

4). As a result, the tap water is introduced into the urine input tank 10 and accumulates, so that the level sensor 11 detects whether or not the liquid level of the tap water has reached a predetermined value (ST35).
Detection continues until the time is up (ST3).
6). When the time is up, that is, when the tap water does not accumulate despite the tap water being introduced into the urine input tank 10, the process proceeds to ST111 in FIG.
Is determined to be a closed state error and an alarm sounds (ST11).
2).

When tap water accumulates in the urine input tank 10 within a predetermined time, the tap water valve 25 closes and the drain pump 16 operates (ST37). Subsequently, after the dispensing pump 18 has been operated for a certain period of time (ST38), the discharge valve 15 is opened and the cleaning tank valve 24 is closed (ST39). As a result, the tap water in the urine input tank 10 is discharged, so that the level sensor 11 detects whether or not the liquid level of the tap water has reached the 0th place (ST40), and the detection continues until the time is up. Is performed (ST41). When the time is up, that is, when the tap water in the urine input tank 10 is not discharged, the ST in FIG.
The process proceeds to step 101, where it is determined that the discharge valve 15 is in the open state error, and an alarm sounds (ST102).

If the tap water in the urine input tank 10 is drained within a certain period of time, it is determined whether or not the predetermined number of times of washing has been completed (ST42). If No, the processing after ST34 is repeated. In the case of Yes, the operation of the drain pump 16 is stopped, the cleaning tank valve 24 is opened, the drain valve 15 is opened, and the tap water valve 25 is closed (ST4).
3), the urine volume measurement process ends.

On the other hand, the process of receiving the urine sugar level in ST27 is performed as follows. Before the patient puts urine into the urine input tank 10, the urine sugar checker 2 is taken out of its own storage case 3 attached to the urine measuring device 1, and for example, the sensor unit 100 of the urine sugar checker 2 is used for urine collection in a beaker. To measure urinary sugar. After that, the transmission window 105 on the rear end face of the urine sugar checker 2 is turned to the receiving unit 5 of the device 1 and the transmission button 104
By pressing, the data such as the urine sugar level of the urine sugar checker 2 is

(1) Since the urine input tank also functions as the measuring unit, the liquid level of the urine injected into the urine input tank can be measured immediately,
Urine volume measurement time can be reduced. (2) Since the urine input tank also functions as the measuring unit, a liquid supply tube and a connection unit for connecting the urine input tank and the measuring unit are not required, so that dirt does not easily adhere and cleaning is easy. . (3) Since the urine input tank also serves as the measuring section, the space occupied in the apparatus can be reduced, and the apparatus can be easily reduced in size and the measurement capacity can be easily increased. (4) Since the urine liquid level is directly measured in the urine input tank,
There is no need to make corrections using urine specific gravity measurements and urine temperature measurements. Therefore, a complicated temperature measurement circuit and calculation algorithm are not required, and the cost can be reduced. Further, even when the specific gravity measuring means cannot be measured for some reason, the urine volume can be measured, so that troubles can be easily dealt with. (5) The liquid supply system is simplified, the number of valves can be reduced, and reliability can be improved and maintenance can be easily achieved. (6) By adopting a float type level sensor as the level sensor in the measuring section, even if dirt adheres to the measuring tube of the level sensor or bubbles or bubbles are present in the urine, the liquid level of the urine can be reduced. Detection can be easily performed. (7) By adopting a float type level sensor as a level sensor in the measuring section, the liquid level of urine can be measured after waiting for the time until the fluctuation of the liquid level after urine is settled is stopped. The liquid level can be measured in a short time. (8) By adopting a float type level sensor as the level sensor in the measuring section, the shape of the lower part of the urine input tank can be narrowed down and if the float can be ensured to float in the urine, the liquid level can be increased even when the urine volume is small. Measurement is possible. Also, by narrowing down the shape of the lower part of the urine input tank,
Since the resolution for the urine volume below the level sensor can be reduced, the liquid level can be measured with high accuracy.
