Abstract

A medical waste collection system for collecting medical waste material, and a manifold for filtering the waste material and/or coupling a suction tube to the system. The system may include a receiver in which the manifold is configured to be inserted in a proximal direction to facilitate an inlet mechanism moving correspondingly in the distal direction. The manifold may include an arm, a spine, a lock element, and/or a catch each having a surface with a relative position in the proximal-to-distal direction. The rim and the catch may be spaced apart by a void, and the rim may be positioned below the catch. The housing may include a body portion, a first leg extending proximally from the body portion, and a second leg spaced apart from the first leg to define the void. The rim may be on the first leg, and the catch may be on the second leg.

First claim

What is claimed is:

1. A medical waste collection system for collecting medical waste material through a manifold during a medical procedure, the medical waste collection system comprising:
a waste container;
a vacuum source configured to provide a vacuum on said waste container;
a receiver coupled to said waste container and comprising:
a housing comprising an opening into which the manifold is configured to be inserted, said housing further comprising a receiver outlet;
an inlet mechanism coupled to said housing so as to be movable in proximal and distal directions, wherein said inlet mechanism comprises a suction inlet, and a suction outlet in fluid communication with said suction inlet; and
a sled assembly movably coupled to said housing and operably coupled to said inlet mechanism, wherein said sled assembly is configured to be moved in a proximal direction during insertion of the manifold into said receiver in the proximal direction to facilitate said inlet mechanism moving correspondingly in the distal direction to establish fluid communication between said suction outlet and said receiver outlet.

2. The medical waste collection system of claim 1 , wherein said sled assembly is configured to be moved in a distal direction opposite the proximal direction during removal of the manifold from said receiver to facilitate said inlet mechanism moving correspondingly in the proximal direction to break fluid communication between said suction outlet and said receiver outlet.

3. The medical waste collection system of claim 1 , further comprising a transfer gear operatively coupling said sled assembly and said inlet mechanism to facilitate the respective corresponding movements of said sled assembly and said inlet mechanism in the proximal and distal directions.

4. The medical waste collection system of claim 2 , wherein said receiver further comprises a claw coupled to said sled assembly, wherein said claw is configured to selectively engage the manifold facilitate movement of said sled assembly in the distal direction during removal of the manifold from said receiver.

5. The medical waste collection system of claim 1 , wherein said receiver further comprises a sled lock assembly comprising a latch, and a biasing element coupled to said latch and configured to bias said latch to a locked configuration in which said latch selectively engages said sled assembly to prevent movement of said sled assembly in the proximal direction.

6. The medical waste collection system of claim 1 , further comprising a controller in communication with said vacuum source, wherein said receiver further comprises a sensor in communication with said controller and configured to output a signal indicative of a position of said sled assembly in the proximal and distal directions, wherein said controller is configured to control said vacuum source based on the signal from said sensor.

7. The medical waste collection system of claim 6 , further comprising a magnet disposed on said sled assembly and configured to be detected by said sensor.

8. The medical waste collection system of claim 6 , wherein the signal is indicative of whether said manifold is inserted into said receiver to a fully inserted operative position, wherein said controller is configured to prevent operation of said vacuum source based on the signal from said sensor when said manifold is not inserted into said receiver to said fully inserted operative position.

9. The medical waste collection system of claim 1 , wherein said receiver further comprises a first barrier pivotably coupled to said housing, and a first biasing element coupled to said first barrier configured to bias said first barrier towards a closed position to selectively cover at least a portion of said opening of said receiver.

10. The medical waste collection system of claim 9 , wherein said receiver further comprises a second barrier pivotably coupled to said sled assembly and positioned proximal to said first barrier, and a second biasing element coupled to said second barrier configured to bias said second barrier towards a closed position.

11. The medical waste collection system of claim 10 , wherein movement of said inlet mechanism in the distal direction facilitates moving said second barrier from the closed position to an open position in which said suction inlet of said inlet mechanism is exposed to the manifold being inserted.

12. The medical waste collection system of claim 1 , wherein said receiver further comprises a locking assembly comprising a locking member having an engagement surface, a release member coupled to said locking member, and a biasing element biasing said locking assembly to a locked configuration in which said engagement surface engages the manifold in a fully inserted operative position to prevent distal movement of the manifold and said sled assembly.

13. The medical waste collection system of claim 1 , wherein said locking assembly further comprises an actuator coupled to said release member and configured to receive an input from a user to move said locking assembly from the locked configuration to an unlocked configuration in which said engagement surface disengages from the manifold to permit the movement of the manifold and said sled assembly in the distal direction.

14. The medical waste collection system of claim 1 , wherein said inlet mechanism further comprises a first support element spaced apart from said suction fitting and configured to facilitate that the manifold being inserted to a proper insertion depth within said receiver.

15. The medical waste collection system of claim 14 , wherein said inlet mechanism further comprises a second support element spaced apart from said suction fitting and positioned opposite said first support element.
