Abstract
A medical image film-viewing light-emitting diode (LED) illuminator is mainly composed of power supply input, a direct-current constant-current power supply, an LED circuit board, a paster type LED, a light-transmitting plate and a clamping piece mechanism. The paster type LED is adopted to serve as a light-emitting light source, not only enables a light box to become thin, but also reduces manufacturing cost, and greatly improves film-viewing effects simultaneously. The clamping piece mechanism is composed of a fixed magnetic strip and a flexible magnetic roller which are parallelly opposite to each other and have inter-attracting magnetism, and does not damage a film while guarantees reliability of film clamping, and has wide application prospect in medical image diagnosis.
Description
Technical field
The utility model relates to the medical image viewbox in a kind of medicine equipment, particularly a kind of LED medical image viewbox.
Background technology
Up to now, the transmission medium of medical image is widest in area and frequency is maximum still belongs to transparent medical image photo, and such photo relies on uniform penetration light to read sheet, thereby obtains diagnostic information.Regrettably, in a lot of hospitals,, do not cause enough attention so far as yet to the performance and the sight sheet environment requirement of viewbox.
At present, known medical image viewbox is broadly divided into according to the difference of illuminating source: daylight lamp, cold-cathode fluorescence lamp (CCFL), led light source.The brightness of viewbox is an important performance parameter, and according to China's standard (WS2-308+83 of the Ministry of Public Health) regulation, screen center's brightness must not be lower than 1350cd/m2; But (two ends blackout, luminance brightness weakens) and reasons such as luminescent screen is aging, yellowing because the fluorescent tube luminescent properties descends in actual use; Brightness is seriously descended, and CCFL and fluorescent tube are all mercurous, and altitude temperature difference effect is arranged; Be difficult for during low temperature lighting, the light intensity of generation is inhomogeneous, and the sheet effect is seen in influence.The LED viewbox is compared with traditional viewbox has the luminosity height, and the life-span is long, energy-conserving and environment-protective, and advantage such as shock resistance is good, and it is low to generate heat, still, existing LED viewbox is popularized because higher manufacturing cost has restricted it to a certain extent on a large scale.
Spring leaf+ball-type intermediate plate mode that the medical image viewbox adopts on clamping sheet mechanism usually; This mode usually can not clamp film owing to the lax or tired of reed; Cause film to be hung and take off, and the meeting self-locking when film drops of needle roller self-locking clamping sheet mechanism has guaranteed the simple, reliable of gripping film; But needle roller is easy to damage the image sheet.
Summary of the invention
In order to overcome the existing in prior technology problem, the utility model provides a kind of LED medical image viewbox, adopts adopting surface mounted LED as illuminating source, not only makes the lamp box attenuation, and has reduced manufacturing cost, has improved sight sheet effect simultaneously greatly.Adopt soft magnetic pulley formula clamping sheet mechanism, when having guaranteed gripping film reliability, do not damage film again.
The utility model solves the technical scheme that its technical matters adopted: a kind of LED medical image viewbox, mainly form by power supply input, dc constant flowing power, LED wiring board, LED, light-passing board and clamping sheet mechanism.The LED of the utility model adopts SMD; Constitute the positive facade of lamp box in proper order according to front and back by light-passing board, adopting surface mounted LED, LED wiring board and lamp box rear wall; The power supply input is electrically connected with dc constant flowing power through power switch, and dc constant flowing power, power switch and light modulation button are set in light box pedestal.The output terminal of dc constant flowing power is electrically connected with the LED wiring board through the light modulation button, and adopting surface mounted LED evenly distributes and is welded on the LED wiring board.In the lamp box upper ledge, clamping sheet mechanism is set; Clamping sheet mechanism is by fixing magnetic stripe parallel relative composition with soft magnetic pulley; And magnetic is inhaled mutually, fixing light-passing board at interval between magnetic stripe and the soft magnetic pulley, and the crust of soft magnetic pulley is made with the material of quality softness; And soft magnetic pulley can rotate to carrying out both forward and reverse directions with central shaft, has reached the reliable purpose of not damaging film simultaneously again of clamping.
The beneficial effect of the utility model is: adopt adopting surface mounted LED as illuminating source; Not only volume is little; Low cost of manufacture; Easy for operation, and light intensity distributions evenly, no dark space, no stroboscopic, colour temperature is stable, screen is bright, soft more, is improving the eyesight that can protect diagnostic personnel when seeing the sheet effect effectively.Adopt soft magnetic pulley formula clamping sheet mechanism, when having guaranteed gripping film reliability, do not damage film again, for medical imaging diagnosis provides reliable sight sheet instrument.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
