Abstract: Devices and a system for detection of blood within in-vivo fluids are provided. A device comprises a housing that includes a gap. The gap has at least one opening through which in-vivo fluids may enter and/or exit the gap. The device further comprises an illumination source for illuminating the in-vivo fluids in the gap, a light detector for detecting light which passes through the in-vivo fluids in the gap, and flexible fins disposed on the housing in the vicinity of the gap's opening for covering the opening when the fins are folded and for pumping fluids into and out of the opening by repeated closure and opening of the opening by the fins, due to repeated peristaltic waves. This pumping effect may lead to continuous flow of fluids into and out of the opening and thus into and out of the gap of the device.

Abstract translation: 提供了用于检测体内流体内的血液的装置和系统。 一种装置包括包括间隙的壳体。 间隙具有至少一个开口，体内流体可通过该开口进入和/或离开间隙。 该装置还包括用于照射间隙中的体内流体的照明源，用于检测通过间隙中的体内流体的光的光检测器，以及设置在间隙开口附近的壳体上的柔性翅片 用于当翅片被折叠时覆盖开口，并且由于重复的蠕动波，通过由翅片重复地关闭和打开开口来将流体泵入和流出开口。 这种泵送效应可能导致流体连续流入和流出开口，从而进入和流出装置的间隙。
