In a medical equipment 1, a hollow shaft body 2 is made of single-wound or plurally-wound coil line elements 21, and has a cylindrical tip portion 3 formed on a distal end of the hollow shaft body 2, and a manipulative grip 4 connected to a proximal side portion of the hollow shaft 2. At least one of an inner surface and an outer surface of the hollow shaft 2, and at least one of an inner surface and outer surface of the tip portion 3 are provided with a screw-like concave-convex streak of projection 75. This makes it possible to cross the tip portion 3 through the diseased area which resists a dilatation device to cross through. The tip portion 3 is made of a radiopaque material and having a tapered portion 31 at a distal end of the hollow shaft body 2. The hollow shaft body 2 has a diameter-reduced portion 25 at the manipulative grip 4 having a transparent portion 10, through which the diameter-reduced portion 25 is visible from outside.

A steering wheel having an operating portion, a hub portion, a spoke portion, an impact energy absorbing member located on the hub portion for absorbing impact energy, and a pad including a hard insert and a soft cover member integrally covering the insert for covering at least an impact energy absorbing member and a spoke portion. The insert has a plurality of divided parts or a portion or portions of thin wall section to improve an impact energy absorbing effect of the impact energy absorbing member independently of the rigidity of the pad, without the deterioration of the pad.
摘要:
In a recording tape cassette having a front lid for protecting the front part of the cassette, the front lid body being exerted by a spring member normally towards the closed direction when the front lid is assembled on the tape cassette, a temporary spring receiving member is formed on the front lid so that before the front lid is assembled on the cassette, one end of the spring member is temporarily received by the temporary spring receiving member to prevent removal of the spring member from the front lid during the manufacturing process.

A sample separation and adsorption appliance (100) includes a negative electrode (2), a positive electrode (3), a sample separation unit (6) that has a first opening (17) opened to a side facing the negative electrode (2) and a second opening (18) opened to a side facing the positive electrode (3), the sample separation unit containing a separation gel (7), and a slit structure (8) including a slit (1) at a position facing the second opening (18). A transfer film (9) is arranged between the second opening (18) and the slit (1).
摘要:
There is provided a medical guidewire which reduces the resistance with a curved guiding catheter, and has improved durability that can keep the resistance reduced for a long time. A core shaft of the medical guidewire has a second cylindrical part, with a smaller diameter than that of a coiled body, on a proximal end side of the coiled body. This second cylindrical part is coated with a hydrophilic material. Further, the hydrophilic material coated on the second cylindrical part has a larger thickness than a hydrophilic material coated on the coiled body.

In a medical equipment (1), tubular insertion device (10A) and tubular insertion device having the medical equipment (1), the medical equipment (1) has a main body (2) regulated to rotate around an axis of the tubular insertion device (10A) and having a cylindrical body (3) provided in contact with the main body (2) to rotate integrally with the main body (2). A torque regulation mechanism (4) is provided to release the integral rotation in unison with the main body (2) so as to block a torque transmission to the tubular insertion device (10A) when a torque applied to the cylindrical body (3) is more than a predetermined value. The block of the transmission renders it incapable to further rotate the tubular insertion device (10A), whereby preventing a torsional buckling from being induced on the insertion device (10A), and enabling the operator to quickly perceive an excessive torque.
摘要:
A catheter body includes a coil body (10) which is formed by winding or stranding metal wires (12) and having a distal portion (16) and a proximal portion. The distance between coils (12) adjacent to each other in the distal portion (16) is greater than the distance between coils (12) adjacent to each other in the proximal portion (18 or 14). The pitch in the distal portion (16) of the coil body (10) is substantially or nearly the same as the pitch in the proximal portion (18 or 14).
摘要:
This invention relates a mold for molding an air bag cover having an upper wall and a rectangular side wall extended from the back surface of the upper wall. The mold comprises first and second split molds, with the second split mold including a main body, an inner core and pushing pins. The inner core forms the inner surface of the side wall. When the mold opens, the inner core is pulled out from the main body before the pushing pins move.
