Description

The present invention relates to a composite plastic tube capable of transmitting light, and more particularly to a tube formed by winding an optical fiber.

When an object is removed or sucked using a pipe in a place where the light is not bright, the work is often difficult due to the lack of light.

For example, when a dentist performs an intraoral operation, blood and saliva that have flowed out of the patient's wound often mix and accumulate in the oral cavity, obstructing visibility and often affecting the progress of the operation. Therefore, it is necessary to use a suction device. Simultaneously with the operation, blood and saliva are sucked by a tube connected to the sucking device.

However, since the opening width of the mouth is limited and there are many dark areas in the oral cavity due to the structure of the teeth, the doctor moves the patient's head to check where blood and saliva have accumulated. It is very inconvenient for doctors and patients.

Similar problems also occur during treatments that enter the body. For example, all of endoscopes, gastrocameras, large intestine cameras, etc., perform treatment by attaching a light source to the outer edge of the tube, but the larger the volume of the tube that enters, the greater the patient's discomfort. Further, since the light emitting source protrudes from the tube, the weight of the front end of the tube increases, and the operation of moving the tube becomes difficult.

In view of the above-mentioned problems, the present invention uses a tube in which an optical fiber and a plastic are combined, and after entering the light beam from one end of the tube, the light beam is emitted from the other end of the tube, and it is necessary to provide a separate light emitter at the front end. Because the light does not concentrate on one end of the tube, there is no need to avoid the illuminant. In addition, the light is directly irradiated from the front of the tube to the front of the tube, so the irradiation effect is excellent and the situation is grasped. An object of the present invention is to provide a composite plastic tube capable of transmitting light that is easy to control.

  The composite plastic tube capable of transmitting light according to the present invention comprises a plurality of optical fibers and plastic. Each of the optical fibers has a light exit end and a light entrance end, and a light beam enters from the light entrance end and then exits from the light exit end. The plastic is coupled to the side edges of the optical fiber, thereby fixing the relative position of the optical fiber to form a tubular optical fiber composite plastic light conduit. The optical fiber composite plastic optical conduit includes a light exit port and a light entrance tube port, and the light exit end is arranged along the light exit tube port and faces the outside of the light exit tube port.

Since the present invention does not require a separate light emitter as in the case of a conventional tube, the required thickness and shape can be made directly, and the operation is convenient. Moreover, the present invention can be applied to various fields such as endoscope, oral surgery, and maintenance assembly of equipment.

FIG. 4 is an explanatory view showing a state in which the mouth portion of the light emitting tube of the embodiment of the present invention is viewed from the front. A composite plastic tube capable of transmitting light according to an embodiment of the present invention includes a plurality of optical fibers 10 and a plastic 20.

Among them, each optical fiber 10 includes a light exit end 11 and a light entrance end 12. Thereby, the light beam enters from the light input end 12 and then exits from the light output end 11. An optical fiber composite plastic optical conduit 30 is formed by bonding the plastic 20 to the side edge of the optical fiber 10 and fixing the relative position of the optical fiber 10 into a tubular shape. The optical fiber composite plastic light conduit 30 includes a light exit port 31 and a light entrance port 32, the light exit end 11 is arranged along the light exit tube 31, and the light exit end 11 faces the outside of the light exit tube 31. Yes.

Since the optical fiber 10 is coupled to the plastic 20, the light beam enters from the light input end 12, travels toward the light output end 11 along the inside of the optical fiber 10, and is emitted from the light output end 11. By the above, the purpose of irradiating forward can be achieved.

The embodiment of the present invention has a general tube action and can not only carry an object, but can also connect a light source or a video capture device to the light inlet 32, thereby It is possible to illuminate the front of the light exit port 31 and acquire an image.

Etc. can be applied.

Further, in the embodiment of the present invention, it is not necessary to separately provide a light emitting source at the outer edge, so that the weight does not concentrate on one end of the tube, and it is not necessary to operate so as to avoid the protruding light emitting body. The sex becomes much better. In addition, in the case of treatment performed by entering the body, it is only necessary to open an entrance having a size almost equal to the diameter of the tube in the human body, and it is not necessary to open the entrance corresponding to the light source. Becomes smaller.

As shown in FIGS. 2, 3, and 5, the light incident end 12 is concentrated at one place of the light incident tube 32, and each light incident end 12 faces the outside of the light incident tube 32.
