Abstract
Abstract Apparatus for use by chiropractors and other medical professionals has a seat for receiving a patient suspected of having misaligned bone structure. In particular, contact tips are shifted into engagement with the notches below the anteriorsuperior crests of the ilia and any deviation from the proper positions thereof is detected. The seat is provided with a pair of flat, pivotal members supporting the ischia of the patient which may be individually raised to compensate for any measured deviation. The required degree of movement of a given member is registered on a dial, the data thus obtained being used to prepare an ischial lift for the patient.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
Apparatus for determining bone structure misalignment including: a seat for receiving a patient; means supporting said seat at an elevation permitting the patient to assume a normal sitting position when the patient is on the seat; measuring means adjacent said seat and adapted to contact selected skeletal features of the seated patient for detecting any deviation of said features from the proper positions thereof; said seat having a pair of shiftable members for supporting the ischia of the seated patient; and selectively operable means coupled with said members for individually raising and lowering the latter, whereby the positions of said selected skeletal features may be changed while the patient is on the seat to compensate for any deviation from the proper positions thereof detecting by said measuring means.
Claim 2
Dependent Claim
128 words
Apparatus for determining bone structure misalignment including: a seat for receiving a patient; means supporting said seat at an elevation permitting the patient to assume a normal sitting position when the patient is on the seat; measuring means adjacent said seat and adapted to contact selected skeletal features of the seated patient for detecting any deviation of said features from the proper positions thereof; said seat having a pair of shiftable members for supporting the ischia of the seated patient; and selectively operable means coupled with said members for individually raising and lowering the latter, whereby the positions of said selected skeletal features may be changed while the patient is on the seat to compensate for any deviation from the proper positions thereof detecting by said measuring means.
Claim 3
Dependent Claim
51 words
Apparatus as claimed in claim 1; said seat being flat and said members having normal dispositions in which the seat presents a generally horizontal surface for supporting the patient; said selectively operable means, upon said raising and lowering of individual members, shifting the latter out of the plane of said surface.
Claim 4
Dependent Claim
41 words
Apparatus as claimed in claim 1; said seat being provided with means mounting each of said members for pivotal movement about a generally horizontal axis and in a forward direction with respect to the seated patient as the member is raised.
Claim 5
Dependent Claim
57 words
Apparatus as claimed in claim 1; said seat having a flat, generally horizontally disposed front section and being provided with means mounting said members in side-by-side relationship behind said front section for pivotal movement about a generally horizontal axis disposed substantially between the front section and said members and extending laterally with respect to the seated patient.
Claim 6
Dependent Claim
141 words
Apparatus as claimed in claim 1; said measuring means including a pair of measuring structures each having a contact tip adapted for engaging a respective selected skeletal feature, means mounting said measuring structures adjacent said seat for movement of each measuring structure along orthogonal paths of travel toward and away from the seated patient and along the length of the patient above the seat, whereby to bring the tips into contact with respective features, and means operably associated with said measuring structures for indicating the degree of relative movement of the measuring structures away from a predetermined, normal relative disposition corresponding to proper alignment of the skeletal features contacted by said tips, whereby misalignment thereof is indicated if relative movement of said measuring structures away from said normal relative disposition is required to bring said tips into contact with respective features.
Claim 7
Dependent Claim
54 words
Apparatus as claimed in claim 5; said mounting means including a pair of vertically reciprocable carriages for said measuring structures, each carriage having a guide receiving the respective measuring structure for reciprocal, horizontal movement thereof with respect to the carriage, whereby to provide said orthogonal paths of travel of each of said measuring structures.
Claim 8
Dependent Claim
61 words
Apparatus as claimed in claim 5; said indicating means including a pair of indicator elements carried by respective measuring structures and extending therefrom toward each other into closely spaced interrelationship; each of said elements having a pair of marks thereon disposed to represent anterior-posterior and superior-inferior deviations in accordance with the degree of misalignment of corresponding marks of the respective elements.
Claim 9
Dependent Claim
63 words
Apparatus as claimed in claim 1; and means responsive to shifting of each of said members away from a normal disposition thereof for registering the degree of movement of a shifted member away from its normal disposition required to effect proper positioning of said selected Skeletal features, whereby the data thus obtained may be used to prepare an ischial lift for the patient.
Claim 10
Dependent Claim
100 words
Apparatus as claimed in claim 1; said seat being flat and said members having normal dispositions in which the seat presents a generally horizontal surface for supporting the patient; said selectively operable means, upon said raising of an individual member, shifting the latter upwardly out of the plane of said surface; and means responsive to said upward shifting of an individual member for registering the amount of upward movement thereof from its normal disposition required to effect proper positioning of said selected skeletal features, whereby the data thus obtained may be used to prepare an ischial lift for the patient.
Claim 11
Dependent Claim
94 words
Apparatus as claimed in claim 1; said measuring means including a pair of measuring structures each having a contact tip adapted for engaging a respective selected skeletal feature, and means horizontally spaced from said seat and mounting said measuring structures for reciprocal movement of each measuring structure along vertical and horizontal paths of travel; said supporting means including a horizontally reciprocable carrier supporting said seat for movement toward and away from said mounting means, and means for raising and lowering said seat, whereby to facilitate positioning of the patient for contact by said tips.
