The present invention provides a lancet (X1) which includes a case (1) including an internal space (10), and a lancing unit (2) which includes a lancing needle (20) and which is movable within the internal space (10) in an advancing direction from a wait position to an advanced position. The case (1) includes a main body (11) accommodating the lancing unit (2), and a cap (12) which is molded integral with the main body (11) and detachable from the main body (11). The lancing unit (2) includes a cover portion (22) for covering a portion of the lancing needle (20) on the advancing side, for example. The cover portion (22) is detachable together with the cap (12) by exerting a rotational force for rotating the cap (12) and a pulling force for causing relative movement of the cap (12) in the advancing direction for exposing a front end of the lancing needle (20).

An objective is configured with a first partial objective and a second partial objective. The first partial objective, which projects a first field plane onto an intermediate image, has a first, convex mirror and a second, concave mirror. The second partial objective, which projects the intermediate image onto a second field plane, has a third and a fourth mirror, both concave. All of the four mirrors have central mirror apertures. The axial distance between the first and second mirrors is in a ratio between 0.95 and 1.05 relative to the distance between the second mirror and the intermediate image. The axial distance ZM3-IM between the third mirror and the second field plane conforms to the relationship 0.03·DuM3+5.0⁢ ⁢mm<ZM3-IM<0.25·DuM3tan⁡(arcsin⁡(NA)).NA represents the numerical aperture NA in the second field plane, and DuM3 represents the diameter of the third mirror. The objective furthermore has a Petzval radius with an absolute value larger than the distance between the first and second field planes.

A catheter integral with a valved needle-free connector provides a safety catheter device configured to receive a blunt cannula and sharp needle forming an insertion mechanism. The sharp needle is mounted within a needle tube and a control handle is used to slide the sharp needle out of and into the protective needle tube. When the insertion mechanism is mounted to the connector and the control handle is used to slide the sharp needle out of the tube, a blunt cannula first moves into contact with and enters the bore of the valve mechanism of the connector opening it and protecting it from damage that may be caused by the sharp needle. The sharp needle is then extended through the connector and extends out the distal end of the catheter so that a venipuncture procedure may be performed to properly locate the catheter in the patient's circulatory system. Once located, the needle may be retracted into the insertion mechanism, the insertion mechanism disconnected from the connector, and discarded.

A semiconductor device of the present invention includes a film-like flexible substrate having formed thereon a wiring pattern, external connection terminals formed at both end portions of the flexible substrate; and a semiconductor element mounted on a surface side of the flexible substrate, wherein a folded part, which is folded down in U-shape to a back surface side of the flexible substrate, is formed in a fixed state at least at one end portion of the flexible substrate. With this structure, the semiconductor device is COF mounted, and, for example, in its application to a liquid crystal module wherein the semiconductor device is provided so as to face a liquid crystal panel, the external connection terminals of the flexible substrate can be connected to an inner surface of a module main body for a liquid crystal panel in a state the semiconductor element of the semiconductor device faces the inside of the module main body. As a result, since the semiconductor element can be mounted without being projected to the outside of the module main body, the liquid crystal module can be made thinner for the thickness of the semiconductor element.

The invention relates to a medical pump device comprising a rotary valve (13) having preferably only one rectilinear channel (20) which respectively connects the inlet (4) and the outlet (7) of the pump device, or connects the inlet to a pump chamber (15), or said pump chamber to the outlet, upon rotation of the rotary element (19) of the valve. The invention enables a medical pump device to be especially easily produced, said pump device being preferably inserted between an infusion syringe driver or an infusion container and a catheter, and being used to supply small quantities of liquid in an accurately dosed manner.

A seat apparatus allows a seat back to incline forward and to return to an upright position under control from a position inside a passenger vehicle away from the seat. A wire and an operation member are interlocked with an unlocking lever of a reclining unit. The apparatus can include a driving unit which can cause the seat back to incline forward. A rotation unit can be included in a reclining unit. When a notch on a rotating sector gear in the rotation unit comes into contact with a projection on a seat back side bracket, the seat back can be raised from an inclined position to a more upright position.

A shutter device comprises a plurality of shutters. Each of the shutters is provided at a position in the vicinity of a fly's eye lens positioned on the side of a polarization conversion system (one of fly's eye lenses in an integrator lens) and not preventing the passage of effective illuminating light. Each of the shutters is constructed as a first shutter or a second shutter. The first shutter is constructed so as to block an upper one-third region and a lower one-third region of the fly's eye lens, and the second shutter is constructed so as to block an intermediate one-third region of the fly's eye lens

An ophthalmologic photographing apparatus includes an illumination unit configured to illuminate a subject's eye with one of infrared light and visible light, an input unit configured to input a signal to the illumination unit, a measurement unit configured to measure an input time of the signal from the input unit, a detection unit configured to detect that the input time is a predetermined time or longer, and a control unit configured to control the illumination unit according to a detection result by the detection unit to switch from the infrared light to the visible light.

A male housing (10) includes male terminal fittings (11), and a receptacle (12) for surrounding tabs (11a) of the male terminal fittings (11). A female housing (20) includes female terminal fittings (21) and a tubular fitting (29) fittable on the receptacle (12). Since preventing projections (32A, 32B, 32C) for preventing relative displacements of the receptacle (12) and the tubular fitting (29) by contacting the outer surface of the receptacle (12) are provided at the back end of the inner surface of the tubular fitting (29), an abrasion between the terminal fittings (11, 21) due to fine sliding movements resulting from the relative displacements of the two housings (10, 20) can be prevented.

A device for protecting an ear of a subject from auricular haematoma, characterized in that the device comprises an inner member for inserting behind the ear and between the ear and skull of the subject, and a first outer member for placing over the ear of the subject, and for securing to the skull of the subject, the inner member being of a resilient shock absorbing material for acting as a shock absorber between the ear and skull and for cushioning the ear against the skull in the event of a blow, or other force, to the ear.
