FLUID FEEDING DEVICE
Document Type and Number:
Japanese Patent JP2023119788
Kind Code:
A
Abstract:
To provide a fluid feeding device capable of suppressing positional deviations with a luminal organ when retained in the luminal organ, and reducing invasiveness when extracted.SOLUTION: A liquid feeding device 1 which communicates luminal organs 2 and feeds body fluid from one side to the other side retained in the lumen organs 2 on the other side includes: a cylindrical body part 10 having body inflow parts 15 and 15a on one side; a valve part 13 provided on the other side of the body part 10; and a locking part 30 whose tip side projects in a radial direction with respect to a proximal side attached to the outer periphery of the body part 10, and which is locked to a wall 2a of the luminal organs 2 through which the body part 10 penetrates. The locking part 30 deforms the shape from a first shape in which the tip part is directed to the wall 2a of the luminal organs 2 with respect to the proximal end part, to a second shape in which the tip part is directed to the wall 2a of the luminal organs 2 and a side opposite in an axial direction to the body part 10 with respect to the proximal end part when the fluid feeding device is extracted.SELECTED DRAWING: Figure 6
