摘要： A heat exchanger for medical treatment comprises a cylindrical blood passing space and a multiplicity of heat-exchanging tubes disposed inside the blood passing space and extending in the longitudinal direction of the blood passing space and provided with an inner space watertightly separated from the blood passing space for effecting exchange of heat between the blood being passed through the blood passing space and a heat-exchanging medium being passed through the inner spaces of the heat-exchnging tubes through the medium of walls of the heat-exchanging tubes. Blood inlet tube for introducing blood into the blood passing space and a blood outlet tube for discharging blood from within the blood passing space are expended inwardly from outside substantially along a straight lines perpendicular to the longitudinal direction of the blood passing space and tangent to the peripheral plane of the blood passsing space and communicating with the blood passing space. Optionally, the heat exchanger further comprises blood chambers disposed one each near the blood inlet and the blood outlet and each formed of an empty space destitute or devoid of the arrangement of the heat-exchanging tubes, and ribs formed on the inner wall of the blood passing space for retarding the flow of blood.

摘要： A medical instrument having a blood contact portion formed of a hydrophobic material, wherein a surface-active agent safe to a human body is deposited onto part or the entirety of the blood contact portion so that the medical instrument is fully primed by introducing liquid into the instrument without leaving fine bubbles adhered to the surface of the blood contact portion. Further, a method for fabricating a medical instrument is provided, comprising steps of assembling a medical instrument having a blood contact portion formed of a hydrophobic material, and contacting a liquid containing a surface-active agent safe to a human body to the blood contact portion, followed by drying, leaving the surface-active agent deposited onto the surface of the blood contact portion so that the surface-active agent is steadily and readily deposited onto the blood contact portion of hydrophobic material.

摘要： A multitube heat exchanger is used as a heat exchanger for blood in an artificial lung, for example. The multitube heat exchanger has a number of pipes disposed in a tubular housing and heads mounted on the opposite ends of the housing and having fluid inlet and outlet ports, respectively. A fluid flows through the pipes. The housing has fluid inlet and outlet holes for passing another fluid around the pipes. One of the heads which has the fluid inlet port accommodates baffle plates for checking the fluid flow to produce a turbulent fluid flow. With this arrangement, no air bubbles remain trapped in the head with the fluid inlet port, and the fluid can uniformly distributed into the pipes to keep a uniform temperature within the heat exchanger.
