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.
Claims4
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.
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.
