Abstract: The present invention provides surface-modified metals such as metal medical devices, e.g., guide wires, syringe needles, and metal tubes in medical devices or equipment, in which a lubricant layer is firmly bonded to the surface to impart lubricity to the surface, and further to improve the durability of the lubricant layer on the surface, thereby reducing deterioration of sliding properties, as well as methods for modifying a metal surface. The present invention relates to a surface-modified metal having a surface at least partially treated by polymerizing a monomer in the presence of a hydrogen abstraction type photopolymerization initiator.

Abstract: The present invention provides metal medical devices which are provided with sliding properties (lubricity), low protein adsorption properties and low cell adsorption properties and further in which these properties are prevented from deteriorating. The present invention relates to a metal medical device having a surface at least partially treated with a copolymer C of a polymerizable silane compound A and a polymerizable compound B that contains a functional group.

Abstract: Provided are a metal medical device that is excellent in sliding properties, low protein adsorption properties, low cell adsorption properties, and the durability of these properties (the ability to reduce deterioration of sliding properties, low protein adsorption properties, and low cell adsorption properties), and a method for producing the device. The present invention relates to a metal medical device having a surface treatment layer on at least a part of its metal surface, the surface treatment layer including a primer layer formed of an alkoxysilane or a modified alkoxysilane containing a substituted alkoxy group, and a functional layer on the primer layer, the functional layer being formed of a silane compound containing a polyoxyalkylene group, a metal salt-containing hydrophilic group, a halogen salt-containing hydrophilic group, or a fluorine-containing hydrophobic group.

Abstract: Provided are a metal medical device such as a guide wire or stent in which a lubricant layer is firmly bonded to the surface of the metal medical device to impart lubricity and low protein adsorption properties and/or low cell adsorption properties to the surface and, further, improve the durability of the lubricant layer on the surface of the metal medical device, thereby suppressing deterioration of sliding properties and deterioration of low protein adsorption properties and/or low cell adsorption properties, and a method for preparing such a metal medical device. The present invention relates to a metal medical device having lubricity and low protein adsorption properties and/or low cell adsorption properties, the device having a surface at least partially treated with a silane compound containing a functional group, the functional group being a polyoxyalkylene group, a metal salt-containing hydrophilic group, a halogen salt-containing hydrophilic group, or a fluorine-containing hydrophobic group.

Abstract: A breast presser belt 1 comprising a belt body 2 adapted to be removably wrapped around a breast portion of a user, a presser member 3 adapted to extend from the belt body 2 over to the breast portion of a user, and a bag 4 adapted to be inflated by means of an appropriate fluid. The bag 4 is attached to the inner surface of the presser member 3 at a predetermined position. When the bag 4 is inflated, the breast presser belt 1 pressurizes the breast portion of a user and securely fastened to the breast portion. Thus, the pressurizing location of the breast presser belt 1 is prevented from being shifted. The breast presser belt does not require a user or patient to keep still on a bed. Allergic poisoning, previously experienced due to the use of medical adhesive tape, may be obviated. The breast presser belt may be applied to a female having larger breasts.

Abstract: A lumbago correcting belt is disclosed, comprising a belt body adapted to be attached to a lumbar region of a human body to enclose and surround the iliac bones and a pair of tightening members made of a flexible material the tightening members being disposed and spaced from each other on an outer circumferential face of the belt body. Each of the tightening members has two legs branched therefrom which compress the iliac bones by a tightening force selectively given to only one of the two legs. In one embodiment, a first set of engaging means is provided, one member of which is provided at one end portion of the belt body on an outer circumferential face thereof and another member of which is provided at the other end portion of the belt body on an inner circumferential face thereof, and a second set of engaging means is provided on the tightening members at one face of front end portions thereof.

Abstract: This invention relates to a compressive hemostatic belt wherein a cup-shaped rigid case is attached by an attaching device to a predetermined position on a band made of non-stretchable or low-stretchable fiber, nonwoven fabric or film, and a balloon adapted to be inflated by being filled with fluid is received in the rigid case. Preferably, at least the portion of the band which corresponds to the leg when the band is wrapped around the body is shaped in curve form. Buckles may be attached to the opposite ends of the band and a buckle attaching plate may be attached to the rigid case. One end of the band may be provided with projections so that when the band is wrapped around the body, the other end of the band is thrusted on the projections to fix the band in position. If the band is made of adhesive material, more reliable fixing can be achieved. A check valve adapted to prevent fluid from flowing back from the balloon may be removably connected to the balloon to provide for reuse of the check valve.

Abstract: The invention presents a compressive hemostatic belt which is easy to handle and is disposable. A balloon 5 inflatable by filling with fluid is mounted on a specific position of a strip 1 made of non-elastic or low-elastic fiber cloth or the like through mounting means, and a pump 8 and a pressure gauge 9 are connected to the balloon 5 through a check valve 6. The balloon 5 is filled with a fluid by manipulating the pump 8 while observing the pressure gauge 9 to inflate the balloon 5, so that only the area where bleeding is to be stopped is put under pressure. Since the balloon 5 is inflated only on the specified area, a piece of hard material 4 may be placed between the balloon 5 and the strip 1. A non-elastic reinforcing member 11 inserted on the opposite side of the balloon 5 can be varied, or the confronting portion of the strip 1 against the balloon 5 can be formed of a non-elastic reinforcing member stronger than the materials of other portions of the strip.

Abstract: A compressive hemostatic belt which is easily operable and thrown away after use, incorporates a strip (1) in the form of a nonstretch or low-stretch textile fabric, and a bag (5) expansible by being filled with fluid that is attached to the strip at a predetermined position by an attaching device. A pump (8) and a pressure gauge (9) are connected to the bag (5) attached at the predetermined position on the strip (1), so that the bag is expanded by operating the pump so as to fill the bag (5) with a suitable fluid while watching the pressure gauge (9). The bag thus presses down on an area (A) where bleeding is to be stopped.
