Abstract:
Provided is a bioabsorbable stent of which the shape, the degree of decomposition, or the placement site can be checked without incising the patient. The disclosed bioabsorbable stent is made of a bioabsorbable material. The bioabsorbable material contains a contrast medium. Because the present bioabsorbable stent contains a contrast medium, the stent can be detected, for example, from outside the living body. Thus, with the present bioabsorbable stent, it is possible, for example, to check the shape, the degree of decomposition, or the placement site of the stent without incising the patient.

PROBLEM TO BE SOLVED: To provide a defoamer for a blood storage tank of an artificial lung that is manufactured easily.SOLUTION: A defoamer 20 includes a bag-shaped outer layer 21 whose upper side only is open, including main parts 110a and 110b opposed to each other, and an inner layer 22 arranged between a pair of the main parts, including a pair of sub parts 120a and 120b overlapped on the pair of the main parts respectively, and is made of a continuous single sheet material. Slits are formed between edges on the respective upper sides of the main parts and the sub parts that are mutually overlapped. The edges on the respective upper sides of the main parts and the sub parts that are mutually overlapped are continuous in the portion except the slits.

PROBLEM TO BE SOLVED: To easily attach a defoaming material to a defoaming frame without using an adhesive.SOLUTION: A defoaming frame 40 is stored in a housing 10, and a defoaming material 50 is provided in the defoaming frame. Blood flows in the defoaming frame through blood inflow ports 21, 22 provided in an upper part of the housing, passes through a filtering net 47 provided in the defoaming frame, and flows to a blood outflow port 13 provided in a lower part of the housing. The defoaming material 50 has a first lug section 53a, and the defoaming frame 40 has an engaging section 43. The defoaming material 50 is held with the defoaming frame 40 by locking the first lug section 53a in the engaging section 43.
Abstract:
PROBLEM TO BE SOLVED: To fix a blood reservoir tank so that a blood level can be accurately grasped even when a support member is inclined.SOLUTION: A holder for a blood reservoir tank includes an arm member 10 that is attached to a support member, a holding member 30 for holding the blood reservoir tank, and a connection part 50 for connecting the arm member 10 and the holding member 30 together. The connection part 50 makes the holding member 30 connected to a part, to which the holding member 30 is connected, of the arm member 10 in such a manner as to be rotatable around a center line X and a tiltable manner.
Abstract:
PROBLEM TO BE SOLVED: To provide an oxygenator with a built-in filter device in which a large filter membrane area is made to function with a limited blood filling amount and the captured air bubbles are efficiently discharged outside.SOLUTION: A bundle of hollow fiber membranes 12 is stored in a gas exchange unit 3, and a gas containing oxygen is circulated through a lumen. A blood flow path 4 is provided which circulates blood by crossing the hollow fiber membranes, and a filter space 15 adjacent to a blood derivation side of the bundle of the hollow fiber membranes is inserted with a filter 16. An exhaust port unit 17 is provided which forms an exhaust path and brings the filter space into communication with an outer space and enables exhaust of air bubbles. The filter is constituted by a sheet filtering medium 18 folded back in multiple leaves, and mounted by providing membrane surface gaps between membrane surfaces of respective folded leaves. Edge line gaps are formed between an edge line 19 of pleats and an inner circumferential surface of the blood flow path, and the circumferential edge part other than the edge lines of the pleats in the sheet-like filtering medium is brought into close contact with an inner circumferential surface of the blood flow path. The exhaust path is configured to come into communication with the membrane surface gaps, and an opening/closing plug for operating the opening/closing of the exhaust path is provided.
