Of course, the medical device may also be a Computed Tomography (CT) device or other type of imaging device having a dark cylinder 210. In other embodiments of the invention, the medical device may also be other devices that require illumination. The present invention is described by taking a medical apparatus as a scanning imaging apparatus as an example.

It is understood that the medical device has a housing 200 and a barrel 210 disposed in the housing 200. The housing 200 is used for mounting coils, transmitters and the like required for imaging, and the outside of the housing 200 may be provided with operation keys for controlling the medical device. The barrel 210 is a space for scanning imaging. The patient lies on the patient bed, the patient bed moves along the axis of the cylinder 210, the patient on the patient bed is sent into the cylinder 210 of the shell 200, the ray is emitted to the patient by the emitting piece such as a bulb tube and the like in the shell 200, and the ray passing through the patient is received by the receiving piece such as a detector and the like so as to image the focus position of the patient. Because barrel 210 has certain length along axial direction, the sick bed drives the patient and when barrel 210 moved along axial direction, can be in the environment of dark, to the patient that has claustrophobia, can produce fear and uneasy, influences the effect.

Therefore, the lighting device 100 is added on the medical equipment, the barrel 210 of the shell 200 of the medical equipment is irradiated by the lighting device 100, so that the brightness of the barrel 210 is improved, the scanning environment in the barrel 210 is improved, the tension of the claustrophobia patient is relieved, the imaging quality is ensured to be accurate, and the medical staff can conveniently diagnose.

Referring to fig. 1 to 3, in an embodiment, the illumination device 100 includes a light source 110 and a diffraction member 120. The light source 110 is disposed at one end of the housing 200 of the medical device, so that the diffractive part 120 of the cylinder 210 of the housing 200 projects light to correspond to the two light sources 110, so that the light emitted by the light source 110 is projected to the cylinder 210 after passing through the diffractive part 120.

The light source 110 is used to provide illumination and to irradiate light into the barrel 210 of the housing 200 to enhance the brightness inside the barrel 210. Moreover, the light source 110 is located outside the cylinder 210 and projects light into the cylinder 210 in an inclined manner, so that the volume of the cylinder 210 is not reduced, mutual interference between the light source 110 and a transmitting part in medical equipment can be avoided, and the medical equipment is accurate and reliable.
