Infusion/aspiration apparatus with removable cassette
First Claim
1. An infusion/aspiration apparatus comprising:
- a base member;
a first cassette formingi) an aspiration passageway for receiving liquids and materials from a surgical site,ii) a collection area in fluid communication with the aspiration passageway for receiving and collecting said liquids and materials, andiii) a conduit in fluid communication with the aspiration passageway and the collection area for conducting said liquids and material from the aspiration passageway and into the collection area;
means to selectively occlude said conduit to inhibit fluid flow therethrough;
means releasably holding the first cassette on the base member;
a second cassette includingi) a body, andii) an infusion tube connected to and supported by the body for conducting an infusion fluid; and
means releasably holding the second cassette on the base member.

Abstract
An infusion/aspiration apparatus including a base member and first and second cassettes including a base member and first and second cassettes releasably connected to a base member. The first cassette forms an aspiration passageway and a collection area, and the second cassette includes a body and an infusion tube. Preferably, the base member and the second cassette form a vacuum passageway in fluid communication with the aspiration passageway. In operation, an aspiration tube is connected to an inlet of the aspiration passageway, and an outlet of the vacuum passageway is connected to a source of vacuum pressure. An infusion fluid is conducted through the infusion tube and to a surgical site, and that site is aspirated via the aspiration tube. The aspirated materials are drawn into the aspiration passageway and thence into the collection area.

30. An infusion/aspiration apparatus comprising:
-
a base member including a vacuum passageway and a slot extending through the vacuum passageway, wherein the slot separates the vacuum passageway in the base member, forming a first and second sections of the vacuum passageway; a first cassette releasably mounted to the base member, forming i) an aspiration passageway for receiving liquids and materials from a surgical site, and ii) a collection area in fluid communication with the aspiration passageway for receiving and collecting said liquids and materials; a second cassette releasably mounted to the base member, wherein the second cassette and first cassette are separately releasably mounted to the base member, including i) a body having a vacuum passageway therethrough, wherein the vacuum passageway of the cassette body forms a third section of the vacuum passageway located in series between, and in fluid communication with, the first and second sections of the vacuum passageway, when the second cassette is positioned in the cassette receiving slot; ii) an infusion tube connected to and supported by the body for conducting an infusion liquid; wherein when the second cassette is releasably mounted in the receiving slot, the first, second, and third sections of the vacuum passageway are in fluid communication with the aspiration passageway of the first cassette to develop a vacuum pressure in the aspiration passageway when the first cassette is releasably mounted to the base member.
