<P>PROBLEM TO BE SOLVED: To provide a highly accurate device for detecting leakage of drip infusion to detect and announce puffiness of skin caused by the leakage of drip infusion with less number of components at low cost. <P>SOLUTION: The device for detecting leakage of drip infusion finds out the puffiness 10 with the change in height of the skin surface caused by the puffiness 10 of the human skin 9 by applying the same pulse voltage respectively on an electrode 4 for human-skin-puffiness detection and reference electrodes 3a, 3b mounted in the vicinity, and comparing the pulse current values between the human skin 9 and each of the electrodes. The electrode 4 for human-skin-puffiness detection and the reference electrodes 3a, 3b mounted in the vicinity have the similar forms, and the pulse current value between the respective electrode and the skin 9 almost rests on the distance between the respective electrode and the skin. Spacers 8a, 8b are provided to maintain a certain distance between the skin and the reference electrodes 3a, 3b, and the pulse current value of the electrode 4 for human-skin-puffiness detection is compared with the pulse current values of the reference electrodes 3a, 3b as a basis, and the detection result is announced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
