1. Field of the Invention
The present invention relates to a separable illuminating device, and in particular to a hand-held separable medical 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
Since the tube body 30 of the conventional hand-held medical illuminating device is made of a hard metallic material, it is not easy for the medical personnel to adjust the angle or orientation of the illuminating device. Therefore, the light emitting by the illuminating device may be obstructed by some mussel tissue, which results in a fact that the side or corner of the wound of the patient may not be seen and thus generates a trouble for the medical personnel in performing the medical treatment. Further, since the light-emitting source 40 is fixedly connected and thus integrally formed with the interior of the tube body 30, the tube body 30 cannot be replaced upon the damage of the light-emitting source 40. Therefore, the whole set of the hand-held medical illuminating device has to be discarded, causing the waste of medical resources.
In view of the above drawbacks, the present invention provides a separable medical illuminating device. With this arrangement, a light source transmitting assembly and a grip assembly of the medical illuminating device can be separated from each other, thereby replacing the light source transmitting assembly. After the light source transmitting assembly and the grip assembly are separated from each other, they can be stored conveniently. Further, the light source transmitting assembly allows the medical personnel to adjust the angle and orientation of the illuminating device, so that the medical personnel can see every corner of the wound of the patient clearly.
The present invention is to provide a separable medical illuminating device, which includes a light source transmitting assembly and a grip assembly assembled with the light source transmitting assembly. The light source transmitting assembly is constituted of 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 grip assembly is constituted of an elongated cylinder, a light source model and an adapter. The cylinder is provided therein with an accommodating space. The accommodating space is disposed with a lead therein. The outer peripheral surface of an opening of the front end of the cylinder is provided with a threaded surface. The light source module is disposed in the opening at the front end of the cylinder, and is provided with a base body and a light-emitting unit arranged on the base body. The light-emitting unit has a light-emitting diode. The base body is provided with a first electrode and a second electrode. The first electrode and the second electrode are electrically connected with the light-emitting diode. The adapter is provided thereon with an assembling port that allows the connecting body to be inserted therein. A tube body extends from one end of the assembling port. A skirt body extends from one end of the tube body. The interior of the skirt body is in communication with the tube body. The inner wall face of the skirt body is provided with a threaded surface. When the threaded surface is threadedly connected with the threaded surface of the front end of the cylinder, the light source model can be assembled between the opening of the front end of the cylinder and the interior of the skirt body, so that the light-emitting diode can be positioned to correspond to the tube body.
The technical contents and the detailed description of the present invention will be explained with reference to the accompanying drawings.
With reference to
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. The light source transmitting body 1 is provided thereon with a first end 13 and a second end 14. The light source transmitting body 1 is used to transmit a light source (light source generating end) from the second end 14 to the first end 13, thereby providing an illumination. The covering body 12 prevents the light from leaking during the transmission of the light source. The covering body 12 is made of a flexible metallic material. The covering body 12 covers on the optical fiber 11, thereby adjusting the illuminating direction of the optical fiber.
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. 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 the grip assembly (not shown), the projecting ring 32 blocks the front end of an adapter of the grip.
The light source transmitting assembly 10 is constructed as that mentioned in the previous paragraphs.
The grip assembly 20 is constituted of an elongated cylinder 4, a light source module 5 and an adapter 6.
The cylinder 4 is provided therein with an accommodating space 41. The accommodating space 41 is used to accommodate battery 42 and a lead 43 for delivering a power source. The outer peripheral surface of the opening at the front end of the cylinder 4 is provided with a threaded surface 44. The threaded surface 44 is used to connect with the adapter 6.
The light source module 5 is disposed in the opening at the front end of the cylinder 4. The light source module has a base body 51 and a light-emitting unit 52 disposed on the base body 51. The light-emitting unit 52 has a light-emitting diode 521 thereon. The base body 51 is provided with a first electrode 511 and a second electrode 512. The first electrode 511 and the second electrode 512 are electrically connected with the light-emitting diode 521.
The adapter 6 has an assembling port 61 that allows the covering body 3 of the light source transmitting assembly 10 to be inserted therein. A tube body 62 extends from one end of the assembling port 61. A skirt body 63 extends from one end of the tube body 62. The interior of the skirt body 63 is in communication with the tube body 62. The inner wall face of the skirt body is provided with a threaded surface 631. When the threaded surface 631 is threadedly connected with the threaded surface 44 of the front end of the cylinder 4, the light source module 5 can be assembled between the opening of the front end of the cylinder 4 and the interior of the skirt body 63, so that the light-emitting diode 521 is positioned to correspond to the tube body 62. When the light source transmitting assembly 10 is assembled with the grip assembly 20, the distal end of the connecting body 3 of the light source transmitting assembly 10 is inserted into the assembling port 61 of the adapter 6. At this time, the projecting ring 32 of the connecting body 3 blocks at the front of the opening of the assembling port 61.
When the light 7 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 7 transmitted by the optical fiber 11 from leaking, so that the light 7 can be transmitted to the protective body 2 efficiently.
