Methods of assembling a manifold for a medical waste collection system. A flapper valve unit is secured to a head of a cap. A filter element is positioned within a shell. Basket hands of the filter element are fitted between first pairs of ribs of the cap skirt. Fingers of the shell are fitted between second pairs of ribs of the cap skirt. The cap is secured to the shell to cover an open distal end of the shell. A drip stop is secured to the proximal end base of the shell to seat within the outlet opening. Ears may be fitted through holes defined by the flapper valve unit and cap holes defined by the cap so as to snap lock to the head of the cap. The hub of the flapper valve unit may be compressed with the ears snap locked to the head of the cap.

An adjustable connector for refrigerant pipe includes a body, a valve pin is inserted into the body, and the body includes a quick-release assembly and a driving member respectively disposed on a mounting part and an installation part thereof. When the driving member is operated to suppress the pressed end of the valve pin to move the pushing end close to the pocket, the valve spout is opened to pass the refrigerant. Besides, when the driving member is operated to not suppress the pressed end by jumping off itself quickly, the pushing end is moved away from the pocket, so that the valve spout is closed to block the refrigerant.

A fluid coupling has two similar coupling halves, each with a rotary body of a valve. A drive device for closing/opening the valve is associated with each rotary body. Each half has a coupling means for connecting/decoupling the halves by relative rotation. Securing means secure the connection when at least one valve is open and close the two rotary valves to disconnect/connect the halves. The drive device is arranged on one half and has a drive shaft which is associated with a valve shaft of the rotary body of the other half. A locking connection is configured which, when the halves are connected, connects the drive shaft on one half to the valve shaft on the other in a non-rotatable/releasable manner such that the rotation of the rotary body is controllable and relative rotation of the halves is blocked but the relative rotation when the valves are closed is permitted.

A manifold apparatus and method of opening a valve in a medical/surgical waste collection unit. The manifold includes a base at a proximal end with the base defining an opening off center from an axis of the manifold. The manifold further includes two arcuately spaced tabs, each subtending arcs having different arcuate lengths. The manifold is positioned such that the tabs mate with at least two slots of a lock ring of the waste collection unit so as to cause the opening of the manifold to be, upon insertion into a bore of the waste collection unit, in a specific rotational alignment in the bore. The manifold is rotated within the bore to cause a valve disk to move between a first position in which the valve disk blocks fluid flow through the receiver and a second position in which the valve disk allows fluid flow through the receiver.

Manifold for a medical/surgical waste collection assembly. A shell includes a proximal end base, and a lip extending proximally from the proximal end base. The lip extends around an outlet opening defined in the proximal end base that is off-centered to a longitudinal axis of the shell. A cap including a cap head is coupled to a side wall of the shell. A drip stop may be seated within a space defined by the lip to cover the outlet opening. An arcuate section of the lip may be flush with an adjacent section of the side wall. The cap head may define a through hole, and a flapper valve unit may be coupled to the cap head with another component having ears extending through the through hole. A fence may extend from the cap head and configured to be grasped by a user.

A fluid coupling element has a body, a valve with a peripheral groove receiving a sealing gasket, a member for resiliently returning the valve, and a skirt positioned inside the body and movable between a first position axially freed relative to the gasket and a second position radially covering the gasket. The element has at least one hitching member axially secured to the skirt and radially movable between a first radial position for axially securing the skirt and the body and for relative axial movement of the valve relative to the skirt, and a second position for axially securing the skirt and the valve and for relative axial movement of the skirt and the body, in a configuration where the skirt covers the gasket.
