Solution Overview
Problem
Existing cryoablative treatment methods face challenges in efficiently and safely removing exhaust gases generated during procedures, which can expose personnel to harmful substances if vented directly into the atmosphere.
Innovation Solution
A treatment assembly that includes an exhaust catheter with venting capabilities, allowing gases to be collected in a bag or scavenging system and subsequently dissolved into water for safe disposal through plumbing systems, minimizing atmospheric exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If exhaust gases are vented directly into the atmosphere, then removal simplicity is improved, but personnel exposure to harmful substances increases
Solution Approach 1:
The patent introduces water as an intermediary medium between the exhaust gases and the atmosphere. The water absorbs the cryoablative gases through dissolution, preventing direct atmospheric release while protecting personnel. The water acts as a mediator that transfers the harmful substance from the gas phase to a safe liquid phase for disposal through existing plumbing infrastructure.
2Object-affected harmful factors
If a scavenging system is used to collect exhaust gases, then personnel exposure is reduced, but system complexity increases
Solution Approach 1:
The system utilizes the existing plumbing infrastructure of the facility to dispose of absorbed gases, eliminating the need for dedicated exhaust removal equipment. The water absorption process occurs passively as gas bubbles through the water in the sink, and the contaminated water is automatically drained through the existing drain system, requiring no additional active components.
3Object-affected harmful factors
If exhaust gases are collected in a bag, then atmospheric release is prevented, but additional removal steps are required
Solution Approach 1:
The patent exploits the phase transition of cryoablative gases from gaseous to dissolved state when contacted with water. This phase change allows the gases to be captured and contained in the liquid phase within the sink, preventing atmospheric release. The dissolved gases are then removed with the water flow through the plumbing system, eliminating the need for separate bag evacuation procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively removes cryoablative exhaust gases by dissolving them into water for safe disposal, preventing direct atmospheric release and ensuring environmental safety.
Implementation Method 1
the water flow may be constricted to reduce the pressure, and continues into drain. The constricted fluid flow creates a low pressure within a suction attachment extending from the housing to create a Venturi effect. This low pressure created within the suction attachment may then suction the exhaust gas from the bag, through exhaust line, and into contact with the water flowing through the housing where the exhaust gas may dissolve into the flowing water for draining directly into the drain.
Implementation Method 2
The constricted fluid flow creates a low pressure within a suction attachment extending from the housing to create a Venturi effect. This low pressure created within the suction attachment may then suction the exhaust gas from the bag, through exhaust line, and into contact with the water flowing through the housing

AI summary
Exhaust removal apparatus and methods for cryogenic treatment are described herein. The apparatus may generally include a housing having an inlet for fluidly coupling to a source of water and an outlet for fluidly coupling to a drain, and a suction chamber in fluid communication with the housing, wherein the suction chamber is further configured to be detachably coupled to an exhaust collection reservoir having a volume of exhaust gas. Introduction of water through the inlet generates a pressure reduction within the suction chamber such that the volume of exhaust gas is drawn from the exhaust collection reservoir and into the housing for dissolving into the water and out through the drain.
