摘要： A method for molding a tube for guiding a rod-like medical instrument into a living body, which includes a tubular body made of a synthetic resin and having a longitudinal hollow portion to permit the passage of the rod-like medical instrument. The whole of the tubular body is formed to have a chemical uniformity, but at least one brittle portion such as a weld line is longitudinally formed over the entire length (or almost the entire length except tip portion) of the tubular body.

摘要： Medical instrument introduction cannula, which is useful as a guide means for introducing and indwelling a rod-like medical instrument such as a catheter and a guide wire. This cannula is removed after use from the medical instrument by being splitted. This cannula is formed of a hollow tubular body having a strip member consisting of a material different from the other portion of the tubular body, which extends over the entire or almost the entire length of the tubular body. The strip member has a weld line along the length of the strip member, or consists of a resin which exhibits a good bonding property only to one of the other components forming the tubular body. The tubular body can be splitted by way of the weld line or the removal of the strip member having such a bonding property. The method of manufacturing the medical instrument introduction cannular by a two-color extruder is also disclosed.

摘要： There is disclosed a guiding tube for introducing rod-like medical instruments such as a catheter, which can be easily split and removed from, for example, a catheter, after the catheter inserted through the guiding tube has been attached to a blood vessel. The guiding tube comprises a main body provided with a longitudinal slit and formed of a mixture of first and second materials and a stripe detachably embedded liquid-tight in the slit of the main body and formed of a third material which exhibits a good bonding to the second material, but a poor bonding to the first material.

摘要： An extruder apparatus for molding a tube used for guiding a rod-like medical instrument into a living body. The resulting tubular body is made of a synthetic resin and has a longitudinal hollow portion to permit the passage of the rod-like medical instrument. The whole of the tubular body is formed to have a chemical uniformity, but at least one brittle portion such as a weld line is longitudinally formed over the entire length (or almost the entire length except the tip portion) of the tubular body. The brittle portion is formed by a die including a nozzle having a resin flow passageway of annular cross section. At least one baffle extends radially into the passageway for substantially temporarily splitting the flow which is then recombined to form the brittle portion.

摘要： A method of firmly securing a catheter body to a surface portion of human skin, without causing the catheter body to be bent or reducing the diameter of the inner passage of the catheter body. This method employs a catheter-securing member which comprises a cylindrical body for allowing the catheter body to be slidably inserted therein, and a slit is provided along the axial direction of the cylindrical body. In this method a ligature is first pierced through a surface portion of human skin and tied over the surface of human skin, leaving a pair of free end portions extending out of the skin, and then the cylindrical body is secured with the free end portions of the ligature by winding the ligature around the cylindrical body and fastening them.

摘要： A flowmeter has a main body having fluid inlet and outlet passages and a vertical fluid channel formed in the main body and having one end communicating with the inlet passage and the other end communicating with the outlet passage. The vertical fluid channel has a first passage and a second passage having a cross-sectional area larger than that of the first passage. The first passage has therein a float for regulating a flow rate of the fluid flowing therethrough, and is tapered to have a cross-sectional area increasing from the inlet passage side toward the outlet passage side such that the float remains in position when the fluid passes through the first passage. The second passage has therein a valve for opening the second passage when the fluid is to flow therethrough and for closing the second passage when the fluid is not to flow therethrough. The valve has a projection for moving the float toward the inlet passage when the second passage is closed. The float and the valve have specific gravities larger or smaller than that of the fluid.

摘要： A medical instrument-guiding tube for guiding a catheter or other rod-like medical instrument into a blood vessel. This guiding tube comprises a hollow tube body and at least one linear body integrally joined to the tube body along the longitudinal direction of the tube body. The plastic resin forming the tube body has a poor compatibility with that of linear body. The tube body and the linear body are engaged together through a complementary concave-convex engagement which can be disengaged with a reasonable force.

摘要： A guide wire includes a core possessing a distal end part and a proximal end part, a distal covering layer covering the distal end part of the core, and a proximal covering layer covering the proximal end part of the core. The proximal covering layer includes a first layer that covers the surface of the core, and a second layer that partly covers the surface of the first layer. The first layer has a first part which is not covered by the second layer and a second part which is covered by the second layer, and the surface of the second part is tightly surrounded by the proximal end of the distal covering layer.
