Abstract
A vacuum pump capable of pumping solid, liquid and gas, or any combination thereof, including a drive (40) and a manually disengageable pumping system connected thereto. The pumping system is composed of a two- or three-chambered canister (1, 18, 21) within which solids, liquids, and gases can be separated from one another. A highly flexible diaphragm (24), attached to the canister and sealed against it circumferentially, facilitates this separation, when reciprocating and pumping. The components of the pumping system are designed to be disposable, and the two- or three-chambered canister provides for a highly efficient pumping system that is significantly smaller in size than those previously known. The pump is particularly useful for medical applications.
Claims14
Pumping apparatus, comprising
- a drive unit with a driving element, and
- a pump unit attachable to and detachable from said drive unit, said pump unit including a pumping chamber and a pump member with a reciprocable drive member, said pump member defining part of said pumping chamber, said pumping chamber being adapted to expand and contract for pumping by two-way forced reciprocation of said pump member under action of said reciprocable drive member;
- wherein said pump unit and said drive unit comprise a means for attaching said pump unit to said drive unit such as to bring said drive member and said driving element to a position wherein said drive member is generally coaxial with said driving element, providing, during operation of said drive unit, for their engagement and reciprocation of said drive member by means of said driving element.
