Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
A head-worn esophageal varices tube support having a constant tension traction device carried thereby and providing a connecting cable for attachment to the tube comprising: (a) a helmet-like structure to be worn on the head of a patient so as to allow full mobility for use, (b) a bracket extending forwardly from said helmet-like structure for mounting a constant tension traction device in a line substantially the continuation of the patient's nostrils, (c) a constant tension traction device mounted upon said bracket and providing a retractable cable, (d) means mounted on said cable of said constant tension traction device and releasably attached to the esophageal varices tube for mounting the same under constant tension after the same has been inserted in the nostrils of the patient, and (e) means adjustably fixed along the length of said cable to limit up-riding of the tube out of the patient's nostrils by said constant tension traction device.
Claim 2
Dependent Claim
154 words
A head-worn esophageal varices tube support having a constant tension traction device carried thereby and providing a connecting cable for attachment to the tube comprising: (a) a helmet-like structure to be worn on the head of a patient so as to allow full mobility for use, (b) a bracket extending forwardly from said helmet-like structure for mounting a constant tension traction device in a line substantially the continuation of the patient's nostrils, (c) a constant tension traction device mounted upon said bracket and providing a retractable cable, (d) means mounted on said cable of said constant tension traction device and releasably attached to the esophageal varices tube for mounting the same under constant tension after the same has been inserted in the nostrils of the patient, and (e) means adjustably fixed along the length of said cable to limit up-riding of the tube out of the patient's nostrils by said constant tension traction device.
Claim 3
Dependent Claim
34 words
A head-worn esophageal varices tube support as defined by claim 1 wherein said helmet-like structure comprises a forehead rib, cheek ribs and adjustable bands for mounting the same on the head of a patient.
Claim 4
Dependent Claim
68 words
A head-worn esophageal varices tube support as defined by claim 1 wherein said means mounted on the cable of the constant tension traction device for holding the esophageal varices tube under constant tension comprises a releasable clamp, said clamp consisting of a pair of curved jaws normally spring biased into an open position and a manually operable cam member for closing said jaws upon said esophageal varices tube.
Claim 5
Dependent Claim
33 words
A head-worn esophageal varices tube as defined by claim 3 wherein said helmet-like structure comprises a forehead rib, cheek ribs and adjustable bands for mounting the same on the head of a patient.
Claim 6
Dependent Claim
34 words
A head-worn esophageal varices tube support as defined by claim 4 wherein said helmet-like structure comprises a forehead rib, cheek ribs and adjustable bands for mounting the same of the head of a patient.
Claim 7
Dependent Claim
62 words
A head-worn esophageal varices tube support as defined by claim 1 wherein said means adjustably fixed along the length of the cable to limit up-riding of the tube comprises an adjustable stop, including a wedge lock for fixedly attaching the same, a preselected point along the length of the cable extending between the constant tension traction device and the esophageal varices tube.
Claim 8
Dependent Claim
34 words
A head-worn esophageal varices tube support as defined by claim 6 wherein said helmet-like structure comprises a forehead rib, cheek ribs and adjustable bands for mounting the same on the head of a patient.
Claim 9
Dependent Claim
68 words
A head-worn esophageal varices tube support as defined by claim 6 wherein said means mounted on the cable of the constant tension traction device for holding the esophageal varices tube under constant tension comprises a releasable clamp, said clamp consisting of a pair of curved jaws normally spring biased into a open position and a manually operable cam member for closing said jaws upon said esophageal varices tube.
