<p>Disclosed are a leakage detection unit which can detect the occurrence of extravasation with increased accuracy, and a system equipped with the leakage detection unit. The leakage detection unit (60) is provided with: a plurality of sensor units (61A-61C), each of which has a light emission element which irradiates a predetermined wavelength of light on a part of the body of a test subject, and a light reception element which receives the reflected light; and a support body (63) which supports the plurality of sensors. The plurality of sensor units (61A-61C) are disposed on the support body (63) so as to be located around an injection needle tip (P1) when viewed from above. The location on the support body (63) at the top of the tip (P1) is hollow, enabling palpation.</p> |
