Abstract
The utility model relates to an accessory of a beam-defining clipper of a medical X-ray machine, in particular to a filter switching device for the beam-defining clipper of the X-ray machine. The filter switching device comprises a mounting substrate, and at least one filter arranged on a ray outlet of the mounting substrate; the filter is fixed at the front end of the filter substrate; the filter substrate close to the filter is provided with a strip slot; the filter substrate is positioned above the mounting substrate through a rotating shaft penetrating through the strip slot; the filter substrate moves along the rotating shaft under the action of external force; connecting lugs are fixed on the mounting substrate and are fixedly provided with leaf springs for limiting the filter substrate; the leaf springs limit the filter substrate through clamping parts arranged on lugs of the filter substrate; and the tail of the filter substrate is fixedly provided with an operating handle. By the structure, the filter switching device has the advantages that harmful ray filtering accuracy is effectively improved, the probability of misdiagnosis of medical staff due to medical devices is reduced, and the filter switching device is convenient to operate.
Description
Technical field
This utility model relates to medical X ray machine beam-defining clipper accessory, specifically is a kind of raising to the filter switching device shifter of harm ray filtering accuracy and easy to operate X-ray production apparatus beam-defining clipper.
Technical background
Prior art X-ray production apparatus beam-defining clipper according to different cases and the needs that reduce the human injury, is to come unnecessary harm ray is filtered through filter in use.
The filter switching device shifter of prior art is through on the X-ray production apparatus beam-defining clipper housing above the X ray exit wound of bullet, offering a groove, and the medical worker directly inserts the bar groove to realize the filtration to unnecessary harm ray with filter.But this structure because the quality of fit that weares and teares between making reduces, and generation can't reach the filter effect of expection, produces unnecessary damages to human body between filter and the bar groove in life-time service; And because filter and bar groove be along with the passing of service time, the gap between them is increasing, makes easily to cause doctor's mistaken diagnosis by airborne granule foreign entering X ray exit wound of bullet, brings unnecessary damages to patient.
In sum, the filter switching device shifter filtering accuracy of prior art hangs down and causes medical worker's mistaken diagnosis easily.
Summary of the invention
The purpose of this utility model provides the filter switching device shifter of a kind of raising to harm ray filtering accuracy and easy to operate X-ray production apparatus beam-defining clipper.
For realizing that the technical scheme that this utility model purpose adopts is: a kind of filter switching device shifter of X-ray production apparatus beam-defining clipper; Comprise installation base plate, be arranged on the filter of a slice at least of installation base plate ray outlet top, the front end that filter is fixed on the filter substrate; Filter substrate near filter is provided with the bar slotted eye; The filter substrate is positioned at the installation base plate top through the rotating shaft that penetrates in the bar slotted eye, and the filter substrate moves along rotating shaft under external force; Be fixed with engaging lug on the said installation base plate, be fixed with the spring leaf that the filter substrate is spacing on the engaging lug, spring leaf carries out spacing through the Access Division that is arranged on filter substrate upper protruding block to the filter substrate.The tail end of said filter substrate is fixed with operating handle.
Because said structure; This utility model in use; Have only operating handle to be exposed at outside the X-ray production apparatus beam-defining clipper housing outward, effectively improved to the filtering accuracy of harm ray with reduced the medical worker because medical apparatus and instruments causes the probability of mistaken diagnosis, make that simultaneously operation is more convenient.
Description of drawings
The device of this utility model can further specify through the indefiniteness embodiment that accompanying drawing provides.
Accompanying drawing 1 is the structural representation of this utility model.
Among the figure: 1, installation base plate; 2, filter; 3, bar slotted eye; 4, filter substrate; 5, operating handle; 6, rotating shaft; 7, spring leaf; 8, engaging lug; 9, Access Division; 10, bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is described further:
Referring to accompanying drawing 1; The filter switching device shifter of the X-ray production apparatus beam-defining clipper in the accompanying drawing; Comprise installation base plate 1, be arranged on the filter of a slice at least 2 of installation base plate 1 ray outlet top, the front end that filter 2 is fixed on filter substrate 4; Filter substrate 4 near filter 2 is provided with bar slotted eye 3, and filter substrate 4 is positioned at installation base plate 1 top through the rotating shaft 6 that penetrates in the bar slotted eye 3, and filter substrate 4 moves along rotating shaft 6 under external force; Be fixed with engaging lug 8 on the said installation base plate 1, be fixed with the spring leaf 7 that filter substrate 4 is spacing on the engaging lug 8, spring leaf 7 carries out spacing through the 9 pairs of filter substrates in Access Division 4 that are arranged on filter substrate 4 upper protruding blocks.During use, in the housing that installation base plate 1 is installed in X-ray production apparatus beam-defining clipper ray outlet top, controlled filter plate base 4 moves along rotating shaft 6; After moving into place, spring leaf 7 snaps in the Access Division 9, and realization is spacing to filter 2; Filter substrate 4 because bar slotted eye 3 is spacing to it, makes it can not collide other parts of X-ray production apparatus beam-defining clipper when rotating shaft 6 is moved; Improved filtering accuracy, reduced the medical worker simultaneously because medical apparatus and instruments causes the probability of mistaken diagnosis to harm ray.
For ease of medical worker's operation, the tail end of the said filter substrate 4 of the foregoing description is fixed with operating handle 5.
For further improving filtering accuracy, the said filter 2 of the foregoing description is two-layer, connects through bearing pin 10 between the filter substrate of upper and lower layer filter 2.
In sum, this structure has effectively improved the filtering accuracy of harm ray and has reduced the medical worker because medical apparatus and instruments causes the probability of mistaken diagnosis, makes that simultaneously operation is more convenient.
