摘要： A catheter introducer includes a hollow sheath extending continuously from a base end portion thereof to a distal end portion thereof, and a hollow hub having a connection portion for connecting the hub to the sheath in such a manner that the hub and sheath partially overlap. A reinforcing coil body is fitted in the connection portion and extends axially of the sheath from the connection portion toward the distal end of the sheath to a point beyond the connection portion. The hub has a valve for enabling a catheter to be passed therethrough under liquid-tight conditions.

摘要： An instrument for introducing a catheter into a blood vessel includes an inner needle portion having an inner needle, and a dilator portion having a dilator, the latter including first and second insertion portions. The first insertion portion, which has a comparatively small diameter and a length no less than the distance from a patient's skin to the blood vessel wall, is formed at the tip of the dilator from which a cutting edge at the tip of the inner needle is capable of protruding. The second insertion portion, which has a comparatively large diameter and a length no less than the above length, is smoothly connected to the first insertion portion by a tapered intermediate segment. Also provided is a sheath portion through which a catheter is capable of being passed under liquid-tight conditions.

摘要： A medical instrument having a path for receiving a bar-like member and a combination of valves (16, 17) provided in the path. The combination of valves (16, 17) comprises a first disc-like valve (16) having a first slit (18) open only to one of the end faces thereof and a second slit (19) open only to the other of the end faces thereof, the first and second slits (18, 19) crossing each other to form a distance of intersection inside the first valve (16), and a second disc-like valve (17) disposed in parallel to the first valve (16) and having a slit (21) opening to both end faces thereof. The slit (21) of the second valve (17) crosses the intersection point of the first valve (16) so that the bar-like member passes through the slit (21) of the second valve (17) as well as the intersection of the first valve (16) when it is inserted.

摘要： A medical device has an outer cylinder and an outer cylinder hub (4) which has a hollow portion communicating with the interior of the outer cylinder and fixed to a proximal portion of the outer cylinder. An inner cylinder (3) is provided which can be detachably inserted into the outer cylinder through the hollow portion of the outer cylinder hub (4). An inner cylinder hub (6) is provided which has a hollow portion communicating with the interior of the inner cylinder, can be fitted within the outer cylinder hub (4), and is connected to a proximal portion of the inner cylinder (2). Means is arranged between the outer and inner cylinder hubs (4, 6), for preventing relative axial movement of the outer and inner cylinder hubs (4, 6) when the inner cylinder (3) is inserted into the outer cylinder and the inner cylinder hub (6) is fitted into the outer cylinder hub (4). Means is arranged between the outer and inner cylinder hubs (4, 6), for preventing relative circumferential rotation of the outer and inner cylinder hubs (4, 6).
