Abstract
Abstract A method of forming a disposable suction swab from an elongated stem having an enlarged, resilient tip at one end. The stem is installed in a longitudinal central channel in the tip, and the assembly is then compressed between a pair of displaceable clamp plates, the plates having drill apertures in registration with one another and with the tip being in alignment with the apertures. A hole is then bored through the compressed tip and stem by drilling through the apertures in the clamp plates. The plates are released to eject the formed swab.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
A method of forming a suction swab, comprising the steps of a. installing a resilient compressible tip on an end of an elongated, hollow stem, with the tip enveloping the end of the stem, b. locating the tip between a pair of displaceable clamp plates, the plates each having a drill aperture, with the apertures being in registration with each other and with the tip being in alignment with the apertures, c. compressing the tip between the plates with the stem being located between the apertures, d. boring a hole through the compressed tip and the hollow stem by drilling through said apertures, and e. releasing the tip from the plates.
Claim 2
Independent Claim
111 words
A method of forming a suction swab, comprising the steps of a. installing a resilient compressible tip on an end of an elongated, hollow stem, with the tip enveloping the end of the stem, b. locating the tip between a pair of displaceable clamp plates, the plates each having a drill aperture, with the apertures being in registration with each other and with the tip being in alignment with the apertures, c. compressing the tip between the plates with the stem being located between the apertures, d. boring a hole through the compressed tip and the hollow stem by drilling through said apertures, and e. releasing the tip from the plates.
Claim 3
Dependent Claim
21 words
The method according to claim 1 in which method step "d" comprises drilling completely through the apertures of the compressed plates.
Claim 4
Dependent Claim
22 words
The method according to claim 1 in which method step "c" comprises compressing the tip without distorting the shape of the stem.
Claim 5
Dependent Claim
34 words
The method according to claim 1 in which the tip is made of foam having a cell structure, and method step "c" comprises compressing the tip, thereby collapsing the cell structure of the foam.
Claim 6
Dependent Claim
65 words
A suction swab formed in accordance with the method of claim 1, wherein said end of the hollow stem is sealed by said compressible tip and said hole extends laterally through said tip with respect to said hollow stem, is generally round in cross section with a generally constant diameter, and is the only hole in said swab for application of suction to the tip.
Claim 7
Independent Claim
133 words
A method of forming a suction swab, comprising the steps of a. forming a resilient, compressible foam tip for the swab, with the tip having a longitudinal central channel, b. installing the tip on an end of an elongated, hollow stem, with the end of the stem being located in the channel, c. locating the tip between a pair of displaceable clamp plates, the plates each having a drill aperture, with the apertures being in registration with each other and with the tip being in alignment with the apertures, d. compressing the tip between the plates, thereby compressing the foam, with the stem being located between the apertures, e. boring a hole through the compressed tip and the hollow stem by drilling through said apertures, and f. releasing the tip from the plates.
Claim 8
Independent Claim
133 words
A method of forming a suction swab, comprising the steps of a. forming a resilient, compressible foam tip for the swab, with the tip having a longitudinal central channel, b. installing the tip on an end of an elongated, hollow stem, with the end of the stem being located in the channel, c. locating the tip between a pair of displaceable clamp plates, the plates each having a drill aperture, with the apertures being in registration with each other and with the tip being in alignment with the apertures, d. compressing the tip between the plates, thereby compressing the foam, with the stem being located between the apertures, e. boring a hole through the compressed tip and the hollow stem by drilling through said apertures, and f. releasing the tip from the plates.
Claim 9
Dependent Claim
21 words
The method according to claim 6 in which method step "e" comprises drilling completely through the apertures of the clamp plates.
Claim 10
Dependent Claim
22 words
The method according to claim 6 in which method step "d" comprises compressing the tip without distoring the shape of the stem.
Claim 11
Dependent Claim
65 words
A suction swab formed in accordance with the method of claim 6, wherein said end of the hollow stem is sealed by said compressible tip and said hole extends laterally through said tip with respect to said central channel, is generally round in cross section with a generally constant diameter, and is the only hole in said swab for application of suction to the tip.
