摘要:
A blood pump (100) according to the present invention is provided with: a base body (110); a casing (120) fitted in the base body (110); a liquid feeding mechanism housed in a pump chamber formed by being surrounded by the base body and the casing; and a drive body that applies energy to the liquid feeding mechanism.The base body (110) has: a substantially horizontal surface (111) including a first contact surface (113) in contact with the casing (120); and a first engaging section (115) that includes a first taper section (116) that is inclined inward toward the bottom. The casing (120) has: a casing main body (121) wherein a second contact surface (122) is provided at a position corresponding to the first contact surface (113); and a second engaging section (125), which is provided on the end side of the casing (120), and which includes a second taper section (126) that is inclined, in the diameter direction, from an inner end section (127) toward the top. Pressing is performed such that the second engaging section is engaged with the first engaging section, and the second contact surface is in contact with the first contact surface.The blood pump, which eliminates a gap between the second contact surface and the first contact surface, and which has small diameter and volume, can be provided.Une pompe d'assistance circulatoire (100) selon la présente invention comporte : un corps de base (110) ; un boîtier (120) s'insérant dans le corps de base (110) ; un mécanisme d'alimentation en liquide logé dans une chambre de pompe formée en étant entourée par le corps de base et le boîtier ; et un corps d'entraînement qui applique une énergie au mécanisme d'alimentation en liquide. Le corps de base (110) comporte : une surface sensiblement horizontale (111) comprenant une première surface de contact (113) en contact avec le boîtier (120) ; et une première section de mise en prise (115) qui comprend une première section conique (116) qui est inclinée vers l'intérieur et
