Abstract
Abstract The disclosure describes a device for filling and evacuating hollow organs in human and animal bodies. The device is provided with a suction valve adapted to be connected to a catheter or probe, the suction valve being connected, by means of hoselines, to a storage tank for flushing liquids and to at least one collector vessel. The suction valve is in the form of a three-way element, one connection thereof being adapted to be connected directly to a catheter or probe, the inlet and outlet hoselines for the flushing liquid, connected to the said three-way valve, being of sufficient length to permit unobstructed actuation of the said catheter or probe, and of the said three-way valve independently of the storage tank and the collector vessel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
A device for filling and evacuating hollow organs in human and animal bodies, comprising, a catheter probe, an elevated storage tank of adjustable elevation, a collector vessel for liquid, a three-way suction valve, a collector vessel for solid fragments in the form of a waisted vessel made of a transparent material, the upper part of the vessel comprising both an inlet aperture and an outlet aperture serving as an overflow, hose connections between the storage tank and the three-way valve and the catheter probe, and between the three-way valve and the collector vessel for solid fragments and between the collector vessel for solid fragments and the collector vessel for liquid, said storage tank being connected to a liquid level indicator in the form of a transparent sight glass referenced to the level of a patient on an operating table or bed, and a thermometer located within the sight glass for taking the temperature of the liquid therein.
Claim 2
Independent Claim
157 words
A device for filling and evacuating hollow organs in human and animal bodies, comprising, a catheter probe, an elevated storage tank of adjustable elevation, a collector vessel for liquid, a three-way suction valve, a collector vessel for solid fragments in the form of a waisted vessel made of a transparent material, the upper part of the vessel comprising both an inlet aperture and an outlet aperture serving as an overflow, hose connections between the storage tank and the three-way valve and the catheter probe, and between the three-way valve and the collector vessel for solid fragments and between the collector vessel for solid fragments and the collector vessel for liquid, said storage tank being connected to a liquid level indicator in the form of a transparent sight glass referenced to the level of a patient on an operating table or bed, and a thermometer located within the sight glass for taking the temperature of the liquid therein.
Claim 3
Dependent Claim
112 words
A device, as defined in claim 1, in which the suction valve comprises a cone having T-shaped through-passages, the cone being spring-pressed into a valve housing comprising a matching internal conical surface, the housing being provided with a closed oil chamber at the large end of the cone, the spring being arranged in the oil chamber between the cone and a screwed cover sealing off the oil chamber from the outside, the cone being mounted self-lubricatingly in the housing by axial pressure applied to the small end of the cone, the cone being mounted to rotate 180° in the housing, the small end of the cone being connected to an actuating member.
Claim 4
Dependent Claim
73 words
A device, as defined in claim 1 or 2, in which the collector vessel is a waisted vessel of a transparent material, the upper part of the vessel having both an inlet aperture and an outlet aperture serving as an overflow, the lower part of the vessel having a removable opening for calculi and for fragments of calculi adapted to be closed off and sealed, the bottom of the calculus vessel being removable.
