Abstract
A suction head in fluid communication with a pump head provides a sub-ambient working pressure to a target area, enabling drainage thereof to a waste container. The pump head is coupled non-mechanically to a pump drive. A control system for a suction system is also provided.
Claims18
A pump system, comprising:
- a head adapted for being in fluid communication with a target volume;
- a waste container defining a collection volume for collection of materials that may be drained from said target volume;
- and
- a pump apparatus comprising a powered pump drive and a pump head, in operation said pump apparatus being configured for enabling said pump drive to drive said pump head via a non-mechanical coupling arrangement, the pump head being in fluid communication with said head and with said waste container,
- wherein said non-mechanical coupling arrangement comprises a pneumatic coupling arrangement,
- wherein said pump apparatus comprises an actuation chamber that at least during operation of said system, is substantially air-tight and comprises a control volume of air that pneumatically couples the pump drive with the pump head, enabling said pump drive to drive said pump head,
- wherein said pump head is releasably coupled mechanically to said pump drive,
- wherein said actuation chamber comprises a first part, comprised in said pump head, and a second part, comprised in said pump drive, wherein said first part and said second part are configured for being reversibly sealably engaged with one another to define said control volume, when said pump head is coupled mechanically to said pump drive,
- wherein said pump head comprises a pump member in the form of a diaphragm, and said pump drive comprises a reciprocation drive for driving a reciprocating diaphragm member, said diaphragm member being in fluid communication with said actuation chamber only via a first surface thereof during operation of said system, and wherein said pump member and said diaphragm member are in mutually facing relationship in said actuation chamber.

A pump system comprising:
- a pump apparatus comprising a powered pump drive and a pump head, in operation said pump apparatus being configured for enabling said pump drive to drive said pump head via a pneumatic coupling arrangement, the pump head being in fluid communication with said head,
- wherein said pump apparatus comprises an actuation chamber that at least during operation of said system, is substantially air-tight and comprises a control volume of air that pneumatically couples the pump drive with the pump head, enabling said pump drive to drive said pump head,
- wherein said pump head is releasably coupled mechanically to said pump drive,
- wherein said actuation chamber comprises a first part, comprised in said pump head, and a second part, comprised in said pump drive, wherein said first part and said second part are configured for being reversibly sealably engaged with one another to define said control volume, when said pump head is coupled mechanically to said pump drive;
- and
- wherein said pump head comprises a pump member in the form of a diaphragm, and said pump drive comprises a reciprocation drive for driving a reciprocating diaphragm member, said diaphragm member being in fluid communication with said actuation chamber only via a first surface thereof during operation of said system,
- and further comprising at least one pressure sensor in fluid communication with said control volume and configured for monitoring a pressure thereof, and wherein said pump member and said diaphragm member are in mutually facing relationship in said actuation chamber.
4 more elements
A kit for use with a pump system for suctioning fluids from a target volume, comprising:
- a pump head adapted for releasable operative coupling to a powered pump drive unit, said pump head comprising a pump inlet and a pump outlet for enabling working fluid to be pumped through the pump during operation thereof;
- wherein said pump head is configured for being driven by said pump drive via a non-mechanical coupling arrangement,
- wherein said non-mechanical coupling arrangement comprises a pneumatic coupling arrangement, wherein said pneumatic coupling arrangement comprises an actuation chamber that is formed when said pump head is coupled with said powered pump such that at least during operation of said system, said actuation chamber is substantially air-tight and comprises a control volume of air that pneumatically couples the pump drive with the pump head, enabling said pump drive to drive said pump head, and wherein optionally said actuation chamber comprises a first part, comprised in said pump head, and a second part, comprised in said pump drive, wherein said first part and said second part are configured for being reversibly sealably engaged with one another to define said control volume, at least when said pump system is in operation,
- wherein said pump head comprises a pump member in the form of a diaphragm, and said pump drive comprises a reciprocation drive for driving a reciprocating diaphragm member, said diaphragm member being in fluid communication with said actuation chamber only via a first surface thereof during operation of said pump system, and wherein said pump member and said diaphragm member are in mutually facing relationship in said actuation chamber.
1 more element
A method for indirectly monitoring a working pressure generated by a pump apparatus, said pump apparatus comprising a pump head comprising a pump member in the form of a diaphragm pneumatically coupled to a reciprocable diaphragm member of a powered pump drive unit via an actuation chamber comprising a control volume, and wherein said pump member and said diaphragm member are in mutually facing relationship in said actuation chamber, and further comprising monitoring directly a pressure of said control volume.
