2. Description of the Related Art Generally, in an operating room of modern medicine, a waste liquid (urine, blood, etc.) discharged from a patient undergoing an operation is stored in a waste bag via a waste tube, and is stored at regular intervals (about 5 times during the operation). Every minute, every 20 minutes at the bedside, every hour, etc.), the storage amount is measured in time series. Further, the amount of waste liquid is also monitored in the same manner for patients in a hospital room where rest is required. This is because the fluctuation of the amount of waste fluid is similar to blood pressure, body temperature, pulse, etc.
This is because it is important physiological data to know the patient's health condition.

This waste liquid bag is made of a transparent or semi-transparent material having a scale printed on its surface, and is constructed as a flat bag that is deformed and expanded as the waste liquid flows in. The waste bag is
Normally, it is hung on the side of the operating table or bed, but at the time of regular measurement, the nurse holds this waste liquid bag by hand and reads the position of the liquid surface by the scale printed on the surface of the bag, It was necessary to visually check the stored amount and write the numerical value on a predetermined recording sheet.

Further, the waste liquid stored in the waste liquid bag has been designed to be discharged when it is full, or to be discarded together with the bag.

[0005]

In the above-mentioned conventional waste liquid treatment system, the nurse must hold the waste liquid bag with discomfort and directly look at urine and blood repeatedly when measuring the storage amount. .. This is not only a psychologically great burden on the nursing work, which involves a lot of strain and uncomfortable work, but also a physical burden due to lifting the waste liquid bag weighing 2-3 kg. Further, there is a problem that the visual measurement has a large error.

In view of the above points, an object of the present invention is to provide a digital waste liquid measuring device capable of detecting the amount of waste liquid stored inside without touching or looking directly at the waste liquid bag.

[0007]

In order to achieve the above object, the digital waste liquid measuring device of the present invention comprises a base member which can be fixedly mounted on a bed, and a waste liquid bag hook which is supported by the base member and is provided at the measuring end. It has a cantilever type load cell weigher and a display unit that digitally displays the measured weight of the waste liquid by converting it into a volume, and the amount of the stored waste liquid can be detected simply by looking at the numerical value of the display unit. is there.

[0008]

The base is screwed and fixed in place on the bed (or operating table, etc.) so that the cantilever type load cell scale is substantially horizontal. At this time, a waste liquid bag hook is provided at the measurement end of the load cell weighing scale, and the fixed end is cantilevered by the base body. The waste liquid bag communicating with the drainage tube is hung on the hook, and the output of the load cell weight scale is connected to the display means. As a result, the load cell scale is operated according to the weight of the waste liquid stored in the waste liquid bag, and the weight output (output proportional to the amount of bending of the cantilever) is sent to the display means. Then, the amount of waste liquid is calculated from the weight output and the preset specific gravity of waste liquid, and is digitally displayed on the display unit.

The fixed plate 3b is configured to support the fixed end 10a of the load cell weighing scale 10 in a cantilever manner. Here, the weight scale supporting portion 3 can horizontally support the load cell weight scale 10 by adjusting the mounting posture of the base 1.

However, the levelness of the load cell weighing scale 10 is
It is sufficient that it can be visually confirmed to be substantially horizontal. This is because the measurement accuracy required for measuring the amount of waste liquid is several%.
It corresponds to a relatively low level. Further, a gap of about several mm is provided between the load cell weight scale 10 and the bottom plate 3a so that the load cell weight scale 10 does not bend and deform and interfere with the bottom plate 3a. However, when an excessive load is applied to the load cell weight scale 10 and abnormal deformation is likely to occur, the stopper 6 provided on the upper surface of the bottom plate 3a comes into contact with the bottom portion of the weight scale 10 near the measurement end. ,
It is designed to prevent abnormal deformation.

The load cell weighing scale 10 has a built-in weight detecting portion 10x for converting the deflection amount of the measuring bar into an electric signal, so that the weight signal corresponding to the deflection amount can be transmitted via the cord 14.
