Abstract
The utility model discloses a single-photon measurement origin aimer for bone density tester, which comprises a measuring rod 1 and an aiming needle 2, wherein, the aiming needle 2 is vertically welded on the top of the measuring rod 1, a slide base 3 is vertically welded on the bottom of the measuring rod 1, and the slide base 3 is welded in the guide-track groove 5 of a base plate 4. The single-photon measurement origin aimer for bone density tester can position the scanning origin accurately and objectively, and thereby can improve accuracy and repeatability of bone density testing.
Description
Technical field
This utility model relates to a kind of borne densitometers auxiliary device, and particularly a kind of single photon bone density machine is measured the starting point sight.
Background technology
Single photon bone density machine is to measure the density of bone and the content of bone material with dual intensity X line absorption, to diagnose osteoporotic important test instrunment, when detecting, must find the starting point that begins to scan accurately, this starting point generally fixes on the intersection of soft tissue and osseous tissue, otherwise will influence the accuracy of testing result.The method of the sweep starting point of aiming beginning at present is by rule of thumb or uses the order side, no specific purpose tool, therefore, and the starting point instability that aiming begins to scan, not objective, the poor repeatability of measuring has as a result influenced the accuracy that detects.
Summary of the invention
The aiming sweep starting point that the purpose of this utility model is to provide a kind of energy accurate, stable, replace range estimation, measure the starting point sight with the single photon bone density machine that improves the bone density test accuracy.
For reaching above purpose, the technical scheme that this utility model adopted is: this single photon bone density machine is measured the starting point sight, constitute by measuring stick, aiming pin, its aiming pin vertically is weldingly fixed on the top of measuring stick, the bottom vertical welding of measuring stick connects slide, and slide is stuck in the guide-track groove of seat board.This utility model is also implemented by following measure: described seat board is made of top panel and side panel, the length of top panel is 20cm, width is 15cm, the height of side panel is 2cm, establishes guide-track groove in the above in the plate along its length, and the both sides at the upward opening place of guide-track groove are the hypotenuse edge, so that slide combines with guide-track groove closely, measuring stick must not tilt and turn in moving process, establishes hold-down screw on side panel, so that fix with the case lid of borne densitometers; Described aiming pin is the circular cone needle body, and length is 5-10cm, be arranged in parallel with guide-track groove, and side plate one side is pointed in its tip; Described measuring stick is socketed to form by two joints, and every joint is long to be 5-8cm, and the overall diameter of following joint is consistent with guide-track groove upper shed width, on save extension elongation and can realize by outwards lifting.When using this utility model, need to be fixed on seat board on the case lid of radioactive source with hold-down screw, and maintenance is parallel with the active direction of gantry, and at a distance of 2cm, after detected person's limbs are fixing, the direction of measuring stick to bone compressed, make the distance on the surface of soft tissue surfaces and bone be pressed onto minimum, adjust the detector on the gantry, make beyond its receiving orifice and the person under inspection's distance the edge and with the aiming pin on same plane, even the aiming pin on the edge that detects the hole, this edge be with the skeleton that is scanned recently beyond, at this moment gantry is fixed, promptly finished the location work of sweep starting point.
The beneficial effects of the utility model are: compare with range estimation or with the experience location, and sweep starting point accurate positioning, objective, thus can improve accuracy and the repeatability that bone density detects greatly.
