Problems solved by technology

Therefore, in the hose pumps described in Patent Documents 1 and 2, the structure of the mold for producing the connector becomes complicated, and furthermore, there is a problem that the manufacturing cost of the hose pump becomes high.
[0012] On the other hand, in the aforementioned Patent Documents 3 and 4, since the bracket is fixed in advance in a state perpendicular to the pipe, such fixing work is complicated.
Furthermore, care must be taken not to dispose of a plurality of hoses after the brackets are attached without being entangled with the brackets of other hoses, so there is a disadvantage that the handling and management of the tubes becomes complicated.

Abstract

A duct 2 in a tube pump 1 includes a looped large-diameter tube 8, a supply tube 18 connected to an end of the large-diameter tube 8 via a supply-side connector 17, and a discharge tube 19 connected to the other end of the large-diameter tube 8 via a discharge-side connector 17'. The holder 7 includes a pair of stepped engagement recess portions 7D and 7D' that are engageable with outer surfaces of the respective connectors 17 and 17'. The connectors 17 and 17' are held by the stepped engagement recess portions 7D and 7D' of the holder 7, and the holder 7 in such a state is attached to a notch portion 6B of the housing 6. The tube pump 1 enabling easy attachment / detachment of the duct 2 to / from the housing 6 can be provided.

Description

technical field [0001] The present invention relates to a hose pump and, more particularly, to improvements in hose pumps for delivering fluids such as blood or saline. Background technique [0002] Conventionally, a hose pump is known in which a hose is operated by a rotating rotor to deliver a liquid. In particular, the hose pump is used as a blood pump and a rehydration pump of a dialysis device used for dialysis treatment. [0003] In a dialysis apparatus using such a hose pump, installation and removal work of the hose pump and a hose attached to the dialyzer are required before and after dialysis treatment is started. Furthermore, since the order and direction of attaching the hoses to the hose pump are determined for the blood circuit constituted by a plurality of tubes, the work of attaching and detaching the blood circuit to the hose pump is complicated. [0004] Therefore, in order to simplify such cumbersome work, it has been proposed to attach a hose to a pump c...
