Abstract
Abstract A forceplike instrument having rollers for clearing the contents of flexible tubing. The forcep comprises a pair of elongated arms pivotally joined at one set of ends and having handle loops on the other set of ends to receive the fingers of an operator''s hand. Slight matching bends are formed in the arms midway of their length, and each arm is provided with a roller journaled normal to the arm length whereby a flexible tube may be gripped between the rollers when the forcep is closed. A tube restraining link extends between the outer end of one of the rollers and its arm.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
Tube forceps comprising a pair of elongated arm members, pivot means pivotally connecting the arm members together for relative pivotal movement about a pivot axis extending transversely of the arm members at one end thereof, said arm members having a set of ends remote from said pivot means and said set of ends being provided with finger accommodating loops, one for each arm member, accommodating digital manipulation of the arm members in the forceps, first and second parallel rollers disposed in opposed relationship with the axes of the rollers extending transversely of the arm members and paralleling said pivot axis, and means journaling one roller on one arm member and the other roller on the other arm member at a location spaced between said pivot axis of said pivot means and the ends of the arm members having the loops and with the rollers held in a position projecting laterally of corresponding sides of said arm members, said rollers terminating in a set of exposed ends remote from the arm members.
Claim 2
Dependent Claim
171 words
Tube forceps comprising a pair of elongated arm members, pivot means pivotally connecting the arm members together for relative pivotal movement about a pivot axis extending transversely of the arm members at one end thereof, said arm members having a set of ends remote from said pivot means and said set of ends being provided with finger accommodating loops, one for each arm member, accommodating digital manipulation of the arm members in the forceps, first and second parallel rollers disposed in opposed relationship with the axes of the rollers extending transversely of the arm members and paralleling said pivot axis, and means journaling one roller on one arm member and the other roller on the other arm member at a location spaced between said pivot axis of said pivot means and the ends of the arm members having the loops and with the rollers held in a position projecting laterally of corresponding sides of said arm members, said rollers terminating in a set of exposed ends remote from the arm members.
Claim 3
Dependent Claim
51 words
Forceps as claimed in claim 1 wherein said arm members have substantially matching bends intermediate their length, such bends being about axes paralleling said pivot axis, and which further includes a guard member secured to one arm member which includes a portion extending between the rollers at their exposed outer ends.
Claim 4
Dependent Claim
129 words
Tube forceps comprising a pair of elongated arm members, means pivotally interconnecting the arm members accommodating relative swinging about a pivot axis extending transversely of the arm members, said arm members having a set of ends remote from said pivot axis and said set of ends having finger loops integral with the arm members at one end thereof; accommodating digital manipulation thereof, and a pair of rollers journaled on the arm members, one on each, with axes generally paralleling said pivot axis and disposed opposite each other, said rollers being spaced along the length of the arm members from said pivot means and said loops, said rollers projecting laterally of corresponding sides of said arm members and terminating in a set of exposed ends remote from the arm members.
Claim 5
Dependent Claim
129 words
Tube forceps comprising a pair of elongated arm members, means pivotally interconnecting the arm members accommodating relative swinging about a pivot axis extending transversely of the arm members, said arm members having a set of ends remote from said pivot axis and said set of ends having finger loops integral with the arm members at one end thereof; accommodating digital manipulation thereof, and a pair of rollers journaled on the arm members, one on each, with axes generally paralleling said pivot axis and disposed opposite each other, said rollers being spaced along the length of the arm members from said pivot means and said loops, said rollers projecting laterally of corresponding sides of said arm members and terminating in a set of exposed ends remote from the arm members.
Claim 6
Dependent Claim
66 words
The tube forceps of claim 3, wherein the arm members have another set of ends opposite the set of ends having the finger loops, said arm members are pivotally interconnected at said other set of ends of the arm members, and said rollers are journaled on said arm members at a location disposed intermediate the first-mentioned and said other set of ends of the arm members.
