Abstract

Abstract A suction wand having a weighted, resuable handle in cooperation with a disposable suction conduit, the suction conduit having a suction tip at one end and adapted to couple with a suction tubing at the other end. The weighted handle imparts a pre-selected weight and feel to the wand and is selectively reusable with a variety of disposable suction conduit systems.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 117 words
A method for assemblying a suction wand having a disposable fluids handling conduit and a reusable, weighted handle for the fluids handling conduit comprising: injection molding at least one fluids handling conduit comprising a forward suction tip, probe, and a rear handle insert including an external enlarged rearwardly tapering surface spaced from the rear end of said insert; fabricating a handle from metal, the handle having an axial bore generally corresponding to the exterior surface of the insert and a flared end; telescopically inserting the insert portion of the conduit through the handle; and friction-securing the handle to the conduit at the insert by urging the flared end of the metal handle against the enlarged tapering surface.
Claim 2
Independent Claim 117 words
A method for assemblying a suction wand having a disposable fluids handling conduit and a reusable, weighted handle for the fluids handling conduit comprising: injection molding at least one fluids handling conduit comprising a forward suction tip, probe, and a rear handle insert including an external enlarged rearwardly tapering surface spaced from the rear end of said insert; fabricating a handle from metal, the handle having an axial bore generally corresponding to the exterior surface of the insert and a flared end; telescopically inserting the insert portion of the conduit through the handle; and friction-securing the handle to the conduit at the insert by urging the flared end of the metal handle against the enlarged tapering surface.
Claim 3
Independent Claim 156 words
A method for fabricating a suction wand comprising the steps of: a. preparing a handle from metal, the handle having an axial through-bore, one end of the bore having a flared section; b. assembling a hollow fluid conduit comprising: fabricating a hollow tip having a first dimension and pre-selected configuration; fabricating a hollow probe having a second dimension and pre-selected configuration; and fabricating a hollow insert having a flared section at one end and adapted to be telescopically received in the bore, the flared section of the bore adapted to receive the flared section of the insert in a releasable press fit relationship; and bonding the tip to one end of the probe and the insert to the other end so as to align the respective hollows into a fluid conducting passage; and c. press fitting the flared section of the insert portion of the conduit in the flared portion of the bore of the handle.
Claim 4
Independent Claim 156 words
A method for fabricating a suction wand comprising the steps of: a. preparing a handle from metal, the handle having an axial through-bore, one end of the bore having a flared section; b. assembling a hollow fluid conduit comprising: fabricating a hollow tip having a first dimension and pre-selected configuration; fabricating a hollow probe having a second dimension and pre-selected configuration; and fabricating a hollow insert having a flared section at one end and adapted to be telescopically received in the bore, the flared section of the bore adapted to receive the flared section of the insert in a releasable press fit relationship; and bonding the tip to one end of the probe and the insert to the other end so as to align the respective hollows into a fluid conducting passage; and c. press fitting the flared section of the insert portion of the conduit in the flared portion of the bore of the handle.
Claim 5
Dependent Claim 31 words
A method as defined in claim 1 wherein said molding step comprises initially forming a suction tip, probe and handle insert as separate units and thereafter bonding the separate units together.
Claim 6
Dependent Claim 60 words
A method as defined in claim 1 further comprising releasing the disposable conduit from the handle by exerting an axial force thereon directed in alignment with the bore of the handle; removing the conduit from the handle; and inserting into said handle another conduit having an insert which corresponds in size and configuration to the insert of the one conduit.
