Title: Artificial cardiac valve
Inventor: KOZUKA YUTAKA
IPC: A61F2/24
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To ensure the effective valve opening area in the suture, and to close and eliminate the gap between a valve ring of a patient and a sutured valve seat by absorbing the water in the blood by a high water absorbable polymer to swell the sutured valve seat after the suture, by using the high water absorbable polymer on at least a part of the sutured valve seat. SOLUTION: In the sutured valve seat 5 immediately after the transplantation of an artificial cardiac valve, the rapid water absorption is suppressed by the coating cloth 7 of low water permeability, so that a volume can be kept small. As a result, a gap 23 is sometimes generated between a valve ring 21 of a patient and a sutured valve seat 5. When the blood starts its flow accompanying the releasing of the cut-off of the blood flow to a transplantation zone, a high water absorbable polymer 6 included in the sutured valve seat 5 absorbs the water in the blood through the coating cloth 7, and the sutured valve seat 5 is swollen. As a result, a gap 23 between the valve ring 21 of the patient and the sutured valve seat 5 is closed and eliminated. Whereby the generation of the back flow or the like can be prevented without reducing the effective valve opening area.

Abstract: PROBLEM TO BE SOLVED: To stabilize processing concerning film such as photometry or printing or the like by making the light transmissivity of the film stable. SOLUTION: Relating to this device 10; when the film 12 is carried to a specified stop position by a film carrying unit 14, it is irradiated with light from a light source 16 so as to perform scanning and exposure. Meanwhile, when the film 12 is not carried to the prescribed stop position, it is irradiated with the light from the light source 16 and a dimming filter 18 is moved onto an optical path so as to cut light quantity. By operating a keyboard 32, the position of the film 12 is adjusted. When the adjusting time exceeds a prescribed time, the film 12 is shielded from the light by a shutter 20 and the density of the film 12 is restored to be within tolerance, then shielding the light is released so as to perform the scanning and the exposure. When the adjusting time is within the prescribed time, the scanning and the exposure are performed without shielding the light thereafter.
