초록 ▼

A fluid level sensor assembly for monitoring a fluid level in a fluid collection canister of a medical waste fluid collection system. The fluid level sensor assembly includes a fluid level sensor configured for monitoring the fluid level in the fluid collection canister and a fluid level sensor cover configured for preventing direct contact between the fluid level sensor and a fluid in the fluid collection canister. The fluid level sensor cover includes a polymeric cap and polymeric sheath extending from the cap. The elongate tubular sheath surrounds an elongate probe of the sensor with the cap positioned at a base of a sensor body of the sensor to prevent direct fluid contact with the elongate sensor probe and the sensor body.

대표청구항 ▼

1. A medical waste fluid collection system, comprising: a fluid collection canister;a manifold configured to allow for fluid transfer into and/or out of the fluid collection canister;a suction tube in fluid communication with the fluid collection canister, the suction tube for providing a fluid path to the fluid collection canister for medical waste fluid;a vacuum port in fluid communication with the fluid collection canister, the vacuum port configured to connect the fluid collection canister to a vacuum source to provide a vacuum level in the fluid collection canister for use in collecting medical waste fluid;a fluid level sensor attached to a base of the fluid collection canister, the fluid level sensor including an elongate metal probe extending into an interior of the fluid collection canister from the base of the fluid collection canister and a float assembly moveable along the elongate metal probe, the float assembly including a magnet configured to generate an electrical pulse traveling down the elongate metal probe indicative of a level of medical waste fluid in the fluid collection canister;a fluid level sensor cover formed of a polymeric material, the fluid level sensor cover surrounding the elongate metal probe and configured to prevent medical waste fluid within the fluid collection canister from directly contacting the elongated metal probe;wherein the fluid level sensor cover includes: a cap formed of a polymeric material, the cap having a lower end, an upper end and a passage extending therethrough from the lower end to the upper end; an elongate tubular sheath formed of a polymeric material, the elongate tubular sheath having a first end, a second end, and a lumen extending from the first end toward the second end, wherein the first end is attached to the cap such that the passage of the cap is in communication with the lumen of the elongate tubular sheath and the second end of the elongate tubular sheath is closed;wherein the elongate metal probe extends into the lumen of the elongate tubular sheath through the passage of the cap such that the elongate tubular sheath surrounds the elongate metal probe; wherein the fluid level sensor includes a sensor body positioned in a bore in the base of the fluid collection canister, the elongate metal probe extending from the sensor body; wherein the fluid level sensor cover includes a first seal disposed on the lower end of the cap configured to seal against an upper surface of the sensor body. 2. The medical waste fluid collection system of claim 1, wherein the fluid level sensor cover includes an end cap at the second end of the elongate tubular sheath to close off the lumen at the second end. 3. The medical waste fluid collection system of claim 1, wherein the cap includes a base portion at the lower end and a frusto-conical projecting portion extending from the base portion to the upper end of the cap. 4. The medical waste fluid collection system of claim 3, wherein the frusto-conical projecting portion is extendable into a central opening of the float assembly. 5. The medical waste fluid collection system of claim 1, wherein the fluid level sensor cover includes a second seal disposed on the lower end of the cap, the second seal configured to seal against an inner surface of the base of the fluid collection canister. 6. The medical waste fluid collection system of claim 5, wherein the first and second seals are o-ring seals, wherein the second o-ring seal coaxially surrounds the first o-ring seal. 7. The medical waste fluid collection system of claim 1, further comprising: a weld extending circumferentially around the elongate metal probe to weld the elongate metal probe to the sensor body;wherein the weld between the elongate metal probe and the sensor body is positioned in the passage of the cap. 8. The medical waste fluid collection system of claim 1, wherein the elongate tubular sheath extends through a central opening of the float assembly.
