A process in which the main body 10 is attached to and detached from the medical instrument 1 of the present exemplary embodiment configured as described above will be herein described.
The main body 10 may be attached to the medical instrument 1 in such a manner that the main body 10 is seated on the desk 22 of the cart 20 to be positioned between the first front fixing part 32 and the second rear fixing part 44, the front portion of the main body 10 is fixed on the desk 22 using the second front fixing part 34, and the rear portion of the main body 10 is fixed on the desk 22 using the detachable lever 16, the first rear fixing part 42, and the third rear fixing part 46. Accordingly, the medical instrument 1 may be more easily used in hospitals and the like, since the main body 10 may be movable with the cart 20. Hereinafter, a process in which the main body 10 is mounted on the desk 22 will be described in detail.
First, the main body 10 may be disposed between the first front fixing part 32 and the second rear fixing part 44, so that the first front fixing part 32 supports the front surface and both side surfaces of the main body 10, and the first rear fixing part 42 supports the rear surface of the main body 10. Specifically, the left rib 32a of the first front fixing part 32 supports the front surface and left side surface of the main body 10 to thereby prevent the main body 10 to be moved to the left and front, and the right rib 32b of the first front fixing part 32 supports the front surface and right side surface of the main body 10 to thereby prevent the main body 10 to be moved to the right and front. Also, the second rear fixing part 44 may support the rear surface of the main body 10 to thereby prevent the main body 10 to be moved to the back. Thus, the first front fixing part 32 and the second rear fixing part 44 may prevent the main body 10 to be moved forward, backward, right and left.
Next, the location control part 36 of the second front fixing part 34 is backwardly moved 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 surface of the main body 10. The location control part 36 may be coupled and fixed on the guide 24 when the latching part 38 is in close contact with the front surface of the main body 10. 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. Also, since the latching part 38 is in close contact with the front surface of the main body 10, the latching part 38 may function to prevent the main body 10 from being separated from the desk 22 with the third rear fixing part 46
When the second rear fixing part 34 is completely mounted on the desk 22, the coupling part 47 is rotated in a direction in which the contacting portion 48 of the third rear fixing part 46 is forwardly moved, so that the contacting portion 48 of the third rear fixing part 46 is in close contact with the rear surface of the main body 10. As a result, the main body 10 may be arranged on the desk 22 in such a manner as to be sandwiched between the latching part 38 and the contacting portion 48. In particular, since the coupling part 47 has a configuration in which a bolt is coupled with the coupling hole 44a of the second rear fixing part 44, the latching part 38 and the contacting portion 48 may support the main body 10 via a load corresponding to a coupling force of the coupling part 47. Accordingly, the main body 10 may be significantly and stably fixed on the desk 22 by controlling the coupling force of the coupling part 47.
A process in which the main body 10 is separated from the desk 22 will be performed in reverse order of the process in which the main body 10 is mounted to the desk 22. Specifically, the coupling part 47 is backwardly moved so that the contacting portion 48 is separated from the rear surface of the main body 10, and the location control part 36 is forwardly moved so that the latching part 38 is separated from the front surface of the main body 10. When a state where the main body 10 is mounted on the desk 22 by the third rear fixing part 46 and the second front fixing part 34 is released, the main body 10 positioned between the first front fixing part 32 and the second rear fixing part 44 may be upwardly 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.
