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.
Claims9
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.
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.
