The controller may be further configured to steer the assembly based on a current location input signal, and a disposal location input signal from a locator network within the medical facility that is indicative of a location of a disposal station.

Autonomous waste collection assembly and medical waste collection system and methods

A method of operating a waste collection unit including a light assembly separate from a display panel. A vacuum level of the vacuum drawn on a waste canister is measured with a vacuum sensor. The light assembly positioned adjacent a manifold receiver is operated to selectively emit light of a color based on the measured vacuum level. A commanded vacuum level may be received on the display panel, and a colored image indicative of a commanded vacuum level may be displayed on the display panel. The waste collection unit may include plural manifold receivers each configured to receive a manifold. The light assembly that is adjacent the manifold receiver corresponding to the waste canister into which the vacuum is being drawn may be operated to selectively emit light to emit light at different colors or different patterns based on the operating state of the waste collection unit.

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.

Methods of assembling a manifold for a medical waste collection system

A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fitting receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.
