Description

[0001] The present invention relates to a mobile medical diagnostic apparatus,

The present invention relates to a mobile medical diagnostic apparatus, and more particularly, to a mobile medical diagnostic apparatus which can facilitate the movement of a mobile medical diagnostic apparatus by reducing the height of a photographing stand, Device.

Generally, X-ray medical diagnosis devices are used for radiological examination of internal diseases of the human body through an image. The X-ray medical diagnostic device is used to detect whether the human bones are damaged in the chest, tofu, digestive tract, It is a device to analyze.

The conventional radiation diagnostic apparatus is bulky, heavy, and expensive because it is installed in a medical institution and examines a target to be visited. Therefore, in the past, a public health center or a medical organization institution loaded a radiological imaging device on a large bus, shot outside, and performed a simple examination. Then, based on the data, the patient went to a large medical institution and performed appropriate medical treatment.

On the other hand, when a patient suffering an injury such as a fracture occurs in an emergency, the necessity for prompt action becomes high. In response to such a situation, there is a growing interest in development of a device capable of radiological diagnosis in a state of changing a location, Research on related technology development is actively proceeding. Particularly, since the patient can not cope with the danger due to the fracture and the emergency in a short time, the condition of the patient is worsened, resulting in difficulties of subsequent treatment and irreversible sequelae.

Accordingly, it is required to search for a method for enabling rapid imaging and diagnosis of an X-ray image in an emergency situation through a simple equipment, thereby enabling it to be made as a first aid measure. To solve this problem, as shown in Fig. 1, a mobile X-ray medical diagnostic apparatus has been developed.

1, a conventional mobile X-ray medical diagnostic apparatus 1 comprises a mobile body 2, a photographing stand 3, and an X-ray tube 4. The x-ray tube 4 is connected to the photographing stand 3 by the photographing arm 3a. The photographing arm 3a is moved up and down in the height direction of the photographing stand 3. The height of the x-ray tube 4 with respect to the bottom surface is adjusted by the imaging arm 3a. Normally, the X-ray medical diagnostic apparatus 1 can secure a clear x-ray image when the distance between the x-ray tube 4 and the x-ray detector (not shown) is 1800 mm. The X-ray detector is a part where an object to be imaged is photographed by an X-ray irradiated from the X-ray tube 4. [

The photographing stand 3 is made to have a height of about 1.8 m or more with respect to the bottom surface in order to maximize the distance between the x-ray detectors (not shown) and the x-ray tubes 4. Thus, when the portable X-ray medical diagnostic apparatus 1 is moved to another location, the imaging stand 3 obscures the operator's vision and the portable X-ray medical diagnostic apparatus 1 ).

With the angle adjusting stopper 134 engaged with the angle adjusting member 135, the photographing arm 140 maintains a state of being vertically positioned with respect to the adjusting body 131. [

Then, the photographing arm angle adjusting unit 130 is operated as follows in order to position the photographing arm 140 in an inclined position with respect to the adjusting body 131. The knob 133 is rotated by a predetermined angle with respect to the second rotating shaft 133a. At this time, the operation projection 133b pushes the angle adjustment stopper 134 to move toward the bottom surface of the adjustment body 131. [ At this time, the angle adjustment stopper 134 is rotated with respect to the third rotation shaft 134a so that the portion of the angle adjustment stopper 134 abutting the operation projection 133b descends down toward the bottom surface of the adjustment body 131, 135 are separated from the first seating groove 135a.

The large arm portion is rotated at a predetermined angle with respect to the first rotating shaft 132 by releasing the engagement between the angle adjusting member 135 and the angle adjusting stopper 134. [ At this time, the imaging arm 140 is rotated with respect to the first pivot shaft 132 in an upward inclination with respect to the adjustment body 131 by a force applied from at least one pivot 136. Here, at least one shock absorber 136 pushes up the image capturing arm 140 by a predetermined angle with respect to the adjusting body 131 and supports the image capturing arm 140 with respect to the adjusting body 131.

The angle adjusting member 135 is moved together with the photographing arm 140 when the photographing arm 140 is pushed upward by a predetermined angle with respect to the adjusting body 131 by the at least one shoulder 136. [ At this time, the first seating groove 135a of the angle adjusting member 135 is away from the seating projection 134c of the angle adjusting member 135, and the second seating groove 135b is positioned adjacent to the seating projection 134c And is caught and fixed to the seat claw 134c. The imaging arm 140 is fixed at an upward inclined position with respect to the adjustment body 131 in a state in which the second seating groove 135b and the seating projection 134c are engaged with each other.

According to the present invention, the height of the photographing stand can be reduced to secure a viewing angle of a worker when moving the portable medical diagnostic apparatus, thereby facilitating the movement of the portable medical diagnostic apparatus. Further, the present invention can adjust the distance of the x-ray tube to the x-ray detector by adjusting the length of the photographing arm relative to the photographing stand and the angle of the photographing arm instead of lowering the height of the photographing stand.

Although several embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various modifications may be made without departing from the principles and spirit of the invention . The scope of the invention will be determined by the appended claims and their equivalents.
