1. Field of the Invention
The present invention relates to a light source transmitting assembly of an illuminating device, and in particular to a light source transmitting assembly of a hand-held illumination device.
2. Description of Prior Art
Medical instruments have to be combined with some advanced technologies such as micro mechanical and electrical technology, communication technology, material technology and bio-chemical technology to form another industrial technology. Therefore, the development of each kind of technique or technology can promote the industry of medical instruments. Owing to the improved medical instruments, the possibility of the success in the medical treatment can be also increased.
The illuminating device used in a traditional medical treatment can be mounted on a ceiling or wall (such as an operation lamp), and alternatively, can be attached to the head of medical personnel. When the medical personnel perform a medical treatment for a patient, the illuminating device is used to illuminate the position of the wound on the body of the patient, so that the medical personnel can see the wound of the patient clearly. In addition to the above two kinds of illuminating devices, another kind of illuminating device currently used by the medical personnel is a hand-held illuminating device. The volume of such kind of hand-held illuminating device is small, so that it can be used to illuminate the wound of the patient if the above two kinds of illuminating devices cannot work in some instances.
However, as shown in
In view of the above drawbacks, the present invention provides a light source transmitting assembly of a hand-held medical illuminating device, in which the angle or illuminating orientation thereof can be adjusted. With this arrangement, the medical personnel can see every corner of the wound of the patient clearly.
The present invention is to provide a light source transmitting assembly of a hand-held medical illuminating device, which includes a light source transmitting body, a protective body and a connecting body. The light source transmitting body is constituted of an optical fiber and a covering body. The protective body is provided thereon with a conical body. The front end of the conical body has a curved surface and the rear end thereof is provided with a connecting hole. The connecting hole is connected to one end of the light source transmitting body. The connecting body is provided therein with a penetrating hole that allows the other end of the light source transmitting body to be inserted therein. The connecting body can be assembled with a hand-held grip.
The technical contents and the detailed description of the present invention will be explained with reference to the accompanying drawings.
The light source transmitting body 1 is constituted of a linear transparent optical fiber 11 and a covering body 12 covering on the outer surface of the optical fiber 11 (as shown in
The protective body 2 is made of a transparent material and has a conical body 21 thereon. The front end of the conical body 21 is provided with a curved surface 22, and the rear end thereof is provided with a connecting hole 23. The connecting hole 23 is used to connect on the first end 13 of the light source transmitting body 1. The protective body 2 can prevent the sharp corner of the first end 13 from hurting the wound of the patient. Further, the protective body 2 is used to condense or scatter the light transmitted by the light source transmitting body 1 onto a predetermined position.
The connecting body 3 is provided therein with a penetrating hole 31 that allows the second end 14 of the light source transmitting body 1 to be inserted therein. The connecting body 3 is provided thereon with a projecting ring 32. When the connecting body 3 is assembled with a hand-held grip (not shown), the projecting ring 32 blocks the front end of a connecting tube of the grip.
With reference to
When the light 4 is transmitted in the optical fiber 11, the covering body 12 covering on the outer surface of the optical fiber 11 can prevent the light 4 transmitted by the optical fiber 11 from leaking, so that the light 4 can be transmitted to the protective body 2 efficiently.
With reference to
In use, the medical personnel can hold the hand-held grip 5 directly by his/her hand. A battery (not shown) within the hand-held grip 5 lights up a light-emitting body (not shown and can be a bulb or light-emitting diode), the light 4 can be transmitted via the light source transmitting body 1. When the light 4 is transmitted to the protective body 2, the light 4 can be condensed or scattered, and is refracted onto the predetermined position via the curved surface 21 of the protective body 2. In use, if the light projected by the protective body 2 cannot illuminate a certain position of the patient body, the flexible metallic covering body 12 can be used to adjust the angle of illumination, thereby illuminating the predetermined position.
Although the present invention has been described with reference to the foregoing preferred embodiment, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
