Pressure detector for an extracorporeal circulation circuit

The present invention provides a medical material and a blood purification apparatus each having high anti-thrombotic properties and high safety. The apparatus is produced by incorporating therein a medical material which has a hydrophilic copolymerization polymer present on a surface thereof which is to be in contact with blood, wherein particulate protuberances each having a particle diameter of 50 nm or more are present on the surface which is to be in contact with blood at a density of 3 particles/&#x3bc;mor less and the relaxation time of adsorbed water in the hydrophilic copolymerization polymer is 2.5&#xd7;10seconds or shorter and 5.0&#xd7;10seconds or longer at &#x2212;40&#xb0; C.

Medical material and hollow fiber membrane module

A leaf coater, in which a constant quantity of a coating solution is supplied intermittently from a coating solution supply source through a predetermined coating solution quantity intermittent supply means and a coating solution applying means to a blank substrate, for coating blank substrates one by one with the coating solution, characterized in that a coating solution filtration means is provided in the coating solution flow pipeline from said coating solution supply source to the coating solution applying means, and the Young's modulus of the filter medium in the coating solution filtration means is not less than 200 MPa, while the pore size of the filter medium is in the range of 0.05 &mgr;m to 100 &mgr;m; and a method for producing coated substrates using said leaf coater.
