| Claim | A photodynamic therapy device, comprising: a cartridge including: a winding core; and a tube arranged so as to be wound around the winding core; a casing configured to accommodate the cartridge; and a light source, which is arranged inside the casing, and is configured to irradiate the tube with light, wherein the tube arranged around the winding core has a cross section taken along a direction orthogonal to an extending direction of the tube, which has a first dimension in a first direction and a second dimension in a second direction orthogonal to the first direction, the second dimension being smaller than the first dimension, and the second direction is directed outward with respect to the winding core. The photodynamic therapy device according to claim 1, wherein the winding core holds the tube so that a part of the tube extends along a first flat surface. The photodynamic therapy device according to claim 2, wherein the tube has a first portion and a second portion extending in parallel along the first flat surface. The photodynamic therapy device according to claim 3, wherein the tube is arranged so that the first portion and the second portion are spaced apart from each other, wherein the tube further includes a third portion extending along a second flat surface located on a back side of the first flat surface, wherein at least a part of the third portion is located between the first portion and the second portion when viewed in a direction orthogonal to the first flat surface, and wherein a portion of the winding core, which is located on a side closer to the first flat surface with respect to the third portion, is formed of a light-transmissive member. The photodynamic therapy device according to claim 4, wherein the light-transmissive member has a light transmittance of 50% or higher to a center wavelength of the light emitted from the light source. The photodynamic therapy device according to any one of claims 3 to 5, further comprising a cooling fan arranged on the casing, wherein the first portion and the second portion linearly extend in accordance with a direction of installation of the cooling fan. The photodynamic therapy device according to any one of claims 2 to 6, wherein the light source includes a plurality of light-emitting elements arranged on a flat surface opposed to the first flat surface. The photodynamic therapy device according to claims 6 and 7, wherein the casing and the cartridge are arranged so as to define clearances between inner side surfaces of the casing and side surfaces of the cartridge, respectively. The photodynamic therapy device according to any one of claims 1 to 8, wherein at least a part of the winding core, with which the tube is arranged in contact, is mirror finished. The photodynamic therapy device according to any one of claims 1 to 9, further comprising a cover configured to hold the tube in cooperation with the winding core, wherein a part of the cover, which is in contact with the tube, has a flat surface. The photodynamic therapy device according to any one of claims 1 to 10, wherein the winding core has a tubular shape, and has a hollow cavity portion passing from one end to another end of the tubular shape. A photodynamic therapy device cartridge, comprising: a winding core; and a tube arranged so as to be wound around the winding core, wherein the tube arranged around the winding core has a cross section taken along a direction orthogonal to an extending direction of the tube, which has a first dimension in a first direction and a second dimension in a second direction orthogonal to the first direction, the second dimension being smaller than the first dimension, and the second direction is directed outward with respect to the winding core. The photodynamic therapy device cartridge according to claim 12, wherein the winding core holds the tube so that a part of the tube extends along a first flat surface. The photodynamic therapy device cartridge according to claim 13, wherein the tube has a first portion and a second portion extending in parallel along the first flat surface. The photodynamic therapy device cartridge according to claim 14, wherein the tube is arranged so that the first portion and the second portion are spaced apart from each other, wherein the tube further includes a third portion extending along a second flat surface located on a back side of the first flat surface, wherein at least a part of the third portion is located between the first portion and the second portion when viewed in a direction orthogonal to the first flat surface, and wherein a portion of the winding core, which is located on a side closer to the first flat surface with respect to the third portion, is formed of a light-transmissive member. The photodynamic therapy device cartridge according to claim 15, wherein the light-transmissive member has a light transmittance of 50% or higher with respect to a center wavelength of light to be radiated to the tube. The photodynamic therapy device cartridge according to any one of claims 12 to 16, wherein at least a part of the winding core, with which the tube is arranged in contact, is mirror finished. The photodynamic therapy device cartridge according to any one of claims 12 to 17, further comprising a cover configured to hold the tube in cooperation with the winding core, wherein a part of the cover, which is in contact with the tube, has a flat surface. The photodynamic therapy device cartridge according to any one of claims 12 to 18, wherein the winding core has a tubular shape, and has a hollow cavity portion passing from one end to another end of the tubular shape. |
