## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of Korean Patent Application No. 10-2008-0064563, filed on Jul. 3, 2008, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a medical instrument, and particularly, to a medical instrument in which a main body of the medical instrument is easily mounted to or separated from a cart.
2. Description of Related Art
In general, medical instruments are devices used in conducting diagnosis or medical treatment of patients in hospitals or physicians' offices. These medical instruments may be useful to doctors, and allow the doctors to more easily and accurately conduct the diagnosis or medical treatment. With development in techniques, current medical instruments may show a trend of improving performance and convenience, getting smaller, and the like. In particular, when the medical instruments are getting smaller, a high space utilization of the hospital may be acquired due to a reduction in occupied areas of the medical instruments, and convenience of use of the medical instruments may increase due to being easily movable and operated.
However, a conventional medical instrument may have limitations in its convenience of use and miniaturization due to peripheral equipments even though the main body practically conducting medical treatments is relatively small in its size. As a representative example of the peripheral equipments, a structure used for supporting and moving the main body, controlling a height of the main body, and the like, or a storage for safekeeping accessories and consumption goods of the main body may be given. Accordingly, due to the limitation in miniaturization of the conventional medical instruments, a number of medical instruments may be used only in a separate consultation room, operating room, and the like. Also, disadvantageously, results of medical tests conducted using the medical instruments may be outputted as separate documents, photos, and the like, and provided to a doctor and a patient. Also, since the medical instruments may be difficult to be moved to the patient, high quality medical services are difficult to be acquired when medical services are provided at patients' residence.

As for the medical instrument 1 configured as described above, a process in which the main body 10 is mounted to and separated from the desk will be herein described.
The main body 10 is seated on the desk 22 of the cart 20 in such a manner as to be positioned between the first front fixing part 32 and the first rear fixing part 42, the front portion of the main body 10 is fixed to the desk 22 using the second front fixing part 34, and the rear portion of the main body 10 is fixed to the desk 22 using the second rear fixing part 44. Accordingly, the main body 10 and the cart 20 may be simultaneously used, so that the medical instrument is more easily used in hospital and the like. Hereinafter, a process in which the main body 10 is mounted to the desk 22 will be described in detail.
The main body may be positioned between the first front fixing part 32 and the first rear fixing part 42, so that the first front fixing part 32 supports front surface and both side surfaces of the main body 10, and the first rear fixing part 42 supports both side surfaces of the main body 10. Specifically, the left rib 32a of the first front fixing part 32 may support the front surface of the main body 10 and a left side surface of the front portion of the main body 10, thereby preventing the main body 10 from being moved to the left and front, and the right rib 32b of the first front fixing part 32 may support the front surface of the main body 10 and a right side surface of the front portion of the main body 10, thereby preventing the main body 10 from being moved to the right and front. Also, the first rear fixing part 42 may support left and right side surfaces of the rear portion of the main body 10, thereby preventing the main body 10 from being moved to the right and left.
Next, the location control part 36 of the second front fixing part 34 may be moved backwardly along the guide 24 of the desk 22, so that the latching part 38 of the second front fixing part 34 is in close contact with the front portion of the main body 10. When the latching part 38 is in close contact with the front portion of the main body 10, the location control part 36 is coupled with and fixed on the guide 24. Since the latching part 38 is in close contact with the upper surface of the main body 10, the front portion of the main body 10 is prevented from being upwardly separated from the first front fixing part 32.
Referring to FIG. 5, when the second front fixing part 34 is completely fixed as described above, the second rear fixing part 44 is upwardly lifted from the first rear fixing part 42. When the latching protrusion 44b of the second rear fixing part 44 is located above the upper surface of the main body 10, the second rear fixing part 44 is rotated by a certain angle with respect to the first rear fixing part 42, so that the latching protrusion 44b is disposed above the upper surface of the main body 10. Next, when a force exerting on the second rear fixing part 44 is removed, the latching protrusion 44b is brought into close contact with the upper surface of the main body 10 by an elastic force of the third rear fixing part 46. Accordingly, the rear detachable member 40 may prevent the main body 10 from being upwardly separated from the desk 22, and elastically support the rear portion of the main body 10 seated on the desk 22. The rear detachable member 40 may absorb any impact or vibration transmitted to the main body 10 when elastically and upwardly supporting the main body 10, thereby preventing damage to the main body 10.
In addition, a process in which the main body 10 is separated from the desk 10 will be performed in reverse order of the process in which the main body 10 is mounted to the desk 22. Specifically, the second rear fixing part 44 may be rotated to thereby separate the latching protrusion 44b from the upper surface of the main body 10. When the latching protrusion 44b is separated from the upper surface of the main body 10, the second rear fixing part 44 is downwardly moved along the first rear fixing part 42 by the elastic force of the third rear fixing part 46. Next, the location control part 36 is moved to the front to separate the latching part 38 from the front portion of the main body 10. When the second rear fixing part 44 and the second front fixing part 34 are separated from the main body 10, the main body 10 positioned between the first front fixing part 32 and the first rear fixing part 42 is upwardly lifted and separated from the desk 22. As a result, the main body 10 may be movable to various locations, and data stored in the main body 10 may be directly used.
