[0025] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] The terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0028] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] The first embodiment of the present application provides a medical equipment aperture surface light source (hereinafter referred to as surface light source) comprising: a cylindrical mounting cylinder 1, and a light emitting module 2 arranged in the interior of the mounting cylinder 1.

[0030] The installation cylinder 1 can accommodate a patient along its axial direction, and the patient's face is directed to the light-emitting module 2. In an embodiment, the installation cylinder 1 can also be a cylindrical component provided in a medical device, such as a cylindrical cavity around a scanning bed.

[0031] The light-emitting module 2 comprises, from inside to outside, a film layer 201, a diffusion layer 202, a light guide layer 203, and a reflective layer 204. In contrast, the film layer 201 is close to the patient, and the reflective layer 204 is close to the installation cylinder 1.

[0032] Each layer of the light-emitting module 2 is a thin sheet-shaped whole cylinder structure (not spliced), so that the combined light-emitting module 2 is also cylindrical, matched with the inner wall of the installation cylinder 1.

[0033] Each layer of the light-emitting module 2 can be combined together by pasting. For example, the reflective layer 204 is first pasted with the light guide layer 203, and then the diffusion layer 202 is pasted with the light guide layer 203. The above pasting can be fixed by double-sided adhesive. In an embodiment, the diffusion layer 202, the light guide layer 203, and the reflective layer 204 are all provided with oval holes with substantially equal sizes for alignment. When the combination is installed, the oval holes are aligned, and the edges of the holes are wrapped with aluminum foil tape. Finally, the film layer 201 is pasted with the diffusion layer 202 using double-sided adhesive. The film layer 201 is not provided with oval holes to avoid damaging the appearance.

[0034] Specifically, the film layer 201 adopts a film sheet, which is an appearance layer and is made of PET (Polyethyleneterephthalate) or PC (Polycarbonate) material. The surface close to the patient of the film layer 201 can be printed with patterns, such as starry sky patterns, blue sky patterns, and the like. In addition, the film layer also serves as surface protection. The thickness of the film layer is 0.2mm-0.5mm, for example, 0.3mm, 0.4mm, and the like can be selected.

[0035] The diffusion layer 202 can adopt a diffusion plate, which is an appearance piece. The diffusion layer 202 is commonly made of PS (Polystyrene) material and is a common plate structure in surface light sources, used for uniformly diffusing light in the light guide layer 203 and shielding some defects of the light guide layer 203, and thus also called a light uniformization layer. The thickness of the diffusion layer is 0.5mm-1.2mm, for example, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, and the like can be selected.

[0036] The light guide layer 203 is used to conduct light throughout the light guide layer to form a light emitting surface; it is usually made of PMMA (polymethyl methacrylate) material or PC material. The light guide layer 203 has dots, which are laser dots or printed dots; it is also a common plate structure or sheet structure in surface light sources. The thickness of the light guide layer is 0.5mm-2mm, for example, it can be selected as 0.8mm, 1.0mm, 1.2mm, 1.5mm, 1.8mm, etc.

[0037] The reflective layer 204 is made of a reflective material or coated with a reflective material on its surface; the reflective surface of the reflective layer 204 faces the light guide layer 203, which can be used to reflect light from the light guide layer 203 and the light bar back to the light guide layer 203 to increase brightness; it is usually made of PET material (polyethylene terephthalate), which is a common sheet structure in surface light sources. The thickness of the reflective layer is 0.1mm-0.3mm, for example, it can be selected as 0.15mm, 0.2mm, 0.25mm, etc.

[0038] The thickness of the light emitting module 2 obtained by combining the above layers is 1.5mm-7mm, for example, it can be 2mm, 3mm, 4mm, 5mm, 6mm, etc.; it can be arbitrarily curved.

[0039] At least one of the two end portions of the light emitting module 2 along the axial direction is provided with a light bar 3, which can be a LED light bar. Each lamp bead of the light bar 3 is a side light, which is aligned with the end portion of the light guide layer 203, so that the light from the light bar 3 can propagate and diffuse in the light guide layer 203 to form a surface light source. In an embodiment, both end portions of the light guide layer 203 are provided with light bars 3 to provide light sources from two directions and increase brightness.

[0040] When the light emitting module 2 is a cylindrical structure, the light bar 3 is a circular ring. The light bar 3 is connected with a wire harness 4 which runs in the mounting cylinder 1; the wire harness 4 extends to the outside to be connected to a power supply, thereby providing power for the light bar 3.

[0041] The light bar 3 uses a side light, which can be a colored light. When the wire harness 4 is powered on, special light environment can be realized by controlling the color of the light and the time of each lamp bead shining in cooperation with the printing on the surface of the film layer 201; it can bring special experience to the user.

[0042] The two end portions of the light emitting module 2 are also provided with light shielding strips 5. Relative to the light bar 3, the light shielding strips 5 are more external, which can play a role in shielding light to prevent light leakage in the light emitting module 2. When the light emitting module 2 is a cylindrical structure, the light shielding strips 5 are circular rings, which are approximately equal in diameter to the light bar 3.

[0043] In an embodiment, the surface light source is further provided with a breathing navigation light 6, which extends from the outer surface of the mounting cylinder 1 to the outer surface of the film layer 201; the light emitting surface of the breathing navigation light 6 faces the film layer 201, so that it can be seen inside the cylinder.

[0044] The second aspect of the present application provides a medical device, which comprises the surface light source of any of the preceding embodiments; at least a part of the surface light source faces a patient.

[0045] In an embodiment, the medical device is a CT device and a nuclear magnetic resonance device; the surface light source is arranged around a scanning bed of the medical device.

[0046] Finally, it should be noted that: the various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments; the same or similar parts of each embodiment can be referred to.

[0047] The above embodiments are only used to illustrate the technical solutions of the present application but not to limit it; although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical solutions of the present application, they should be covered in the technical solution range of the present application.
