2. Description of the Related Art Conventionally, when an infusion is performed, a pipe line is clogged with clogged platelets in an injection needle, or, conversely, a flow path resistance is rapidly reduced during an infusion and the injection speed of a drug solution is increased. There was a problem, and for this reason, nurses regularly monitored and monitored for any abnormalities.

[0003] Such regular monitoring places a heavy burden on nurses, and as a solution to this problem, there has been one in which monitoring is not required by sending out a chemical solution using a metering pump. .

[0004] However, such a device is expensive and it is difficult to spread it to general clinics and the like.
For this reason, a drip monitoring device has been developed which monitors the drop of the drug solution in the drip balloon and issues an alarm when an abnormality occurs. Such a device has a relatively simple structure and can be supplied at low cost.

A conventional drip monitoring device will be described with reference to FIG. FIG. 8 shows the overall appearance of a conventional drip monitoring device. A balloon holder 3 for holding an infusion balloon 2 is provided on a side surface of the main body 1. The main body 1 is hung from the ceiling with a string (not shown) or the like.

A light emitting diode and a phototransistor (not shown) are provided inside the balloon holder 3, and the light emitted from the light emitting diode is blocked by a droplet 4 dropped inside the drip balloon 2, so that a phototransistor is provided. Output voltage changes, and by detecting this voltage change, the dripping of the chemical solution is detected.

That is, when the number of times the output voltage of the phototransistor drops per unit time is counted by the electronic circuit in the main body 1, it can be determined whether or not the dropping speed of the chemical solution is appropriate.

[0008]

As shown in FIG. 8, in the above-described drip monitoring device, when the liquid medicine is dropped in the drip balloon 2, a droplet 20 is generated and adheres to the drip balloon 2. Then, there is a problem that the droplets 20 adhered to the drip balloon 2 block light emitted from the light emitting diode, and it is not possible to accurately catch the drop of the chemical solution.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drip monitoring apparatus capable of accurately catching a drop of a chemical solution with a simple configuration.
