Abstract: A plasma separation device including a blood inlet and a plasma outlet, the blood inlet comprising an inlet tunnel configured for loading a whole blood sample and a first chamber configured for collecting the whole blood sample; the plasma outlet comprising a second chamber for collecting plasma separated from the whole blood; the device comprising an anti-fouling membrane disposed between the blood inlet and the plasma outlet, the anti-fouling membrane comprising a zwitterionic polyurethane or pre-polymer thereof, wherein the zwitterionic polyurethane or pre-polymer thereof comprises a monomeric unit comprising a zwitterion or precursor thereof and optionally a monomeric unit derived from a polyol, wherein the monomeric unit derived from a polyol is present in a molar ratio in a range of about 0 to about 0.80 relative to the combined amount of monomeric unit derived from a polyol and the monomeric unit comprising a zwitterion or precursor thereof.

Abstract: The present invention is directed to an endoscope that comprises a telescope, an imaging means, an image sensor for converting optical images produced by the imaging means to electrical signals, and a circuit board for receiving and outputting the electrical signals, the imaging means, image sensor and circuit board being located in the telescope. In some embodiments, the endoscope includes a connector that electrically connects the image sensor and the circuit board to form a first assembly.

Abstract: The invention discloses a connector that comprises an insulation body and one or more conductive terminals within the insulation body. The one or more conductive terminals comprise at least one clamping portion to clamp onto the insulation body. The invention further discloses an endoscope, which comprises a telescope, an imaging means, an image sensor that transforms optical signals from the imaging means into electrical signals and a PCB board that organizes and outputs the electrical signals, the imaging means, image sensor and PCB board being located in the telescope, wherein the endoscope further comprises the connector that electrically connects the image sensor and the PCB board to form a first assembly. The invention further discloses a method to make the connector.
