When the elongation length value exceeds the reference value, the controller 500 may determine that the catheter 200 is overextended. In a situation in which the catheter 200 is overextended, a situation in which the catheter 200 is broken or the catheter 200 is separated from the bladder B and/or the storage member 100 may occur. Accordingly, a patient connecting the catheter 200 may be injured or a urinary tract infection may occur through the broken catheter 200 .

As described above, when the elongation sensor unit 310 includes a distance sensor, the length elongation information may include a distance value between the first point and the second point of the catheter 200 . In this case, when the distance value exceeds a preset distance value, the controller 500 may determine that the catheter 200 is overextended.

The controller 500 may determine whether the bottom 130 of the storage member 100 moves while in contact with the object by using the drag information detected by the drag sensor 330 . In an embodiment, the controller 500 may determine whether the object and the bottom 130 are in contact by using distance information between the bottom 130 of the storage member 100 and the object. When it is determined that the floor 130 and the object are in contact, the controller 500 may determine whether the storage member 100 moves by using the location information of the storage member 100 . Accordingly, the controller 500 may determine whether the bottom part 130 of the storage member 100 is attracted. When the storage member 100 is dragged to the bottom, the catheter 200 may be separated from the storage member 100 or the storage member 100 may be damaged. Accordingly, when the user or the like detects the drag on the floor of the storage member 100 in advance, the above situation can be prevented in advance.

When it is determined that the bottom 130 of the storage member 100 is moving while in contact with the object, the control unit 500 may transmit a third output signal to the alarm output unit 600 .

For example, the fourth output signal may include fourth sound type information and fourth sound level information. The fourth sound type information may be different from the first to third sound type information. The fourth loudness information may be different from the first to third loudness information. Accordingly, the patient or caregiver can quickly recognize the state of urine discharge in the storage member 100 .

The communication unit 700 may transmit the fourth output signal transmitted from the control unit 500 to the external terminal. The third output signal may include urine capacity information of the storage member 100 , current time information, patient location information, patient personal information, and the like.
