Abstract

A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.

First claim

What is claimed is:

1. A medical/surgical waste collection unit for use with a manifold, the manifold having a longitudinal axis and an outlet opening that is axially offset from the manifold longitudinal axis, said waste collection unit including:
a first container for holding medical/surgical waste;
a suction pump in fluid communication with said first container, said suction pump configured to draw a suction on said first container;
a receiver attached to said first container, said receiver having: a bore dimensioned to receive the manifold, the bore having an open distal end into which the manifold is inserted, and at least a partially closed proximal end and a longitudinal axis through the bore along which the manifold is inserted into the bore, the longitudinal axis being at an angle that, relative to a horizontal plane, is greater than 2° and less than 45° such that the distal end of the bore is located above the proximal end of the bore; a base that defines the partially closed proximal end of the bore; a conduit that extends from an opening in said base into said first container so that suction drawn on said first container is drawn through the opening in said base; and wherein said receiver is further configured to allow the manifold to rotate in the bore between a first position in which the manifold outlet opening is in registration with the opening in said base into the conduit and a second position in which the manifold outlet opening is located above the position of the outlet opening when the outlet opening is in the first position;
a valve connected to said receiver to regulate fluid flow through the receiver conduit; and
a valve driver connected to said valve for opening and closing said valve, said valve driver accessible through the receiver bore and configured to engage or be engaged by the manifold so that the rotation of the manifold from the first position to the second position actuates said valve driver so as to cause the closing of said valve and the rotation of the manifold from the second position to the first position actuates said valve driver to cause the opening of said valve.

2. The medical/surgical waste collection unit of claim 1 , wherein said valve is a plate that is moveably disposed over said base of said receiver and said plate is formed with an opening wherein, said plate is moveable relative to said receiver between a closed position in which said plate covers the opening in said base into the conduit of said receiver and an open position in which the opening of said plate is in registration with the opening in said base into the conduit of said receiver.

3. The medical/surgical waste collection unit of claim 1 , wherein said valve driver is a pin or a boss that extends into the bore of said receiver and that is configured to engage a complementary portion of the manifold so that the rotation of the manifold in receiver bore results in the actuation of said valve driver.

4. The medical/surgical waste collection unit of claim 1 , wherein said receiver includes an alignment feature that extends into or projects outwardly of the receiver bore, said receiver alignment feature positioned relative to said valve driver so that the engagement of a complementary manifold alignment feature with said receiver alignment feature places a drive member of the manifold in alignment with said valve driver.

5. The medical/surgical waste collection unit of claim 1 , wherein said receiver is further formed to have at least one slot that extends outwardly from the receiver bore, the slot positioned relative to the valve driver so that, the seating of a tab integral with the manifold in the slot places a drive member of the manifold in alignment with said valve driver.

6. The medical/surgical waste collection unit of claim 1 , wherein, said first container, said suction pump and said receiver are mounted to a mobile cart.

7. The medical/surgical waste collection unit of claim 1 , wherein said valve driver is a boss, said boss being dimensioned to seat in the outlet opening of the manifold and being formed with a through bore and said boss is disposed in the receiver bore so that:
when the manifold is in the first position, the boss through bore is in registration with the opening in said base into the receiver conduit; and
the rotation of the manifold from the first position to the second position results in the like rotation of the boss that rotates the boss away from the opening in said base into the receiver conduit.

8. A medical/surgical waste collection unit for use with a manifold, the manifold having a longitudinal axis and an outlet opening that is axially offset from the manifold longitudinal axis, said waste collection unit including:
a first container for holding medical/surgical waste;
a suction pump in fluid communication with said first container, said suction pump configured to draw a suction on said first container;
a first receiver attached to said first container, said first receiver having: a bore dimensioned to receive the manifold, the bore having an open distal end into which the manifold is inserted, and at least a partially closed proximal end and a longitudinal axis through the bore along which the manifold is inserted in the bore, the longitudinal axis being at an angle that, relative to a horizontal plane, is greater than 2° and less than 45° such that the distal end of the bore is located above the proximal end of the bore; a base that defines the partially closed proximal end of the bore; a conduit that extends from an opening in said base into said first container so that suction drawn on said container is drawn through the opening in said base; and wherein said receiver is further configured to allow the manifold to rotate in the bore between a first position in which the manifold outlet opening is in registration with the opening in said base into the conduit and a second position in which the manifold outlet opening is located above the position of the outlet opening when the outlet opening is in the first position
a valve attached to said first receiver for regulating fluid flow through the receiver conduit; and
a pin or a boss that is located in the bore of said receiver, said pin or said boss being connected to said valve to move said valve between an open state and a closed state and being positioned and configured to engage or be engaged by the manifold so that the rotation of the manifold in the bore of said first receiver results in the actuation of said valve driver that results in the opening or closing of said valve.

9. The medical/surgical waste collection unit of said claim 8 , wherein said valve is mounted in the bore of said first receiver for rotation in said receiver.

10. The medical/surgical waste collection unit of claim 8 , wherein:
said valve is a plate that is mounted to said first receiver to move over the opening in said base into the receiver conduit;
said pin or said boss extends from said plate and said pin or said boss and said plate are collectively shaped and positioned in the bore of said first receiver so that:
when the manifold is in the first position, the plate is in the open state and allows fluid communication from the manifold into the opening in said base into the receiver conduit; and
when the manifold is in the second position, said plate is in the closed state and said plate extends over the opening in said base into the receiver conduit.

11. The medical/surgical waste collection unit of claim 8 , wherein:
said valve is a plate that is mounted to said first receiver to move over the opening in said base into the receiver conduit;
the said pin or said boss is a boss and said boss extends from said
