Piezoelectric pump adapter for negative-pressure therapy

A fluid aggregator for aggregating fluid flow into an inlet of a piezoelectric pump, the fluid aggregator comprising:

• a member having a first side, a second side opposite the first side, a first end between the first side and the second side, a second end opposite the first end, and a third end perpendicular to and extending from the first end to the second end;
• a cavity disposed in the second side, the cavity depending into the member and having an area less than an area of the second side;
• a channel disposed in the second side, the channel depending into the member from the cavity, the channel having an area less than the area of the cavity;
• a fluid lumen depending through the member from the channel to the first side;
• and
• a conduit coupled to the first side, the conduit having at least one lumen fluidly coupled to the fluid lumen.

A method for manufacturing a fluid aggregator for aggregating fluid flow into an inlet of a piezoelectric pump, the method comprising:

• providing a block having a first side, a second side opposite the first side, a first end between the first side and the second side, a second end opposite the first end, and a third end perpendicular to and extending from the first end to the second end;
• forming a first recess in the second side, the first recess depending into the block and having an area less than an area of the second side;
• forming a second recess in the second side, the second recess depending into the block from the first recess, the second recess having an area less than the area of the first recess;
• forming a bore depending through the block from the second recess to the first side;
• coupling a conduit to the first side, the conduit having at least one lumen fluidly coupled to the bore;
• forming a first projection extending from the second side and proximate to the first end, the first projection having a length substantially equal to a length of the first end;
• and
• forming a second projection extending from the second side and proximate to the second end, the second projection having a length substantially equal to a length of the second end.
