Abstract: The present invention provides a microchannel structure loaded with a bead having a particle size for detecting whether a biological substance exists in a sample. The microchannel structure includes a structure body for passing a sample through the microchannel structure to have a test or a treatment. The structure body includes a sample entrance having a first aperture to allow the sample passing therethrough, a resistance-increasing section connected with the sample entrance, and having a second aperture being smaller than the first aperture, a detecting section connecting with the resistance-increasing section, and a bead mooring structure coupled to the second end for mooring the bead in the detecting section. The present invention can be used to capture rare cells in a biological system, such as human blood.

Abstract: The present invention provides a microchannel structure for removing circulating tumor cells in a circulating blood system without damaging cells in the blood, wherein the microchannel is loaded with a plurality of beads. The microchannel structure includes: a blood sample entrance passing a blood sample therethrough; a bead mooring section including: a first end connected to the blood sample entrance; a second end; a first section being relatively close to the first end, and cooperating with the first end to cause the plurality of beads to form a bead array in the bead mooring section for decreasing a flow rate of the blood sample through an interstice among neighboring ones of the plurality of beads; and a second section being relatively close to the second end, and causing the treated blood sample to smoothly flow therethrough; and a blood sample exit connected to the second end. One of the applications of this invention is to remove cancer cells in cancer patient's circulating blood system.

Abstract: A connector is provided, including a housing, a conductive contact disposed in the housing, a hollow structure disposed in the housing, and an electrical connecting mechanism. The electrical connecting mechanism is movably disposed in the hollow structure, including a first conductive member, a first spring, a second conductive member, and a second spring. The first spring connects the first conductive member with the hollow structure and provides a first spring force such that the first conductive member protrudes from the hollow structure. The second conductive member and the second spring are movably disposed in the first conductive member, wherein the second spring connects to the first and second conductive members and provides a second spring force such that the second conductive member protrudes from the first conductive member. Specifically, the second conductive member and the conductive contact are spaced apart by a distance.
