Abstract
A portable suction system including a pump device and a removable bag device. The pump device includes a housing defining a recess; a motor assembly positioned within the housing; a first rod at least partially extending from the housing into the recess; and a second rod at least partially extending from the housing into the recess. The first rod and the second rod are driven in response to energization of the motor assembly. The bag device is at least partially positioned within the recess, and the bag device includes: a bag; a vacuum connector; a first piston coupled to the first rod; and a second piston coupled to the second rod.
Claims22
A device comprising:
- a housing defining a recess;
- a motor assembly;
- a barrel drive positioned within the housing and rotatably driven by the motor assembly about a barrel axis;
- wherein a cam is formed in the barrel drive;
- a first follower positioned within the cam;
- a second follower positioned within the cam;
- a first rod coupled to the first follower;
- a second rod coupled to the second follower;
- wherein the first rod and the second rod are at least partially positioned within the recess;
- a pressure sensor;
- a pressure regulator including a cavity, an air inlet, a first port in fluid communication with the cavity by a first passageway, and a second port in fluid communication with the pressure sensor by a second passageway;
- and
- a valve in fluid communication with the cavity;
- wherein the valve selectively communicates the cavity with ambient air from the air inlet to adjust a pressure within the cavity.
