  The means of claim 3 is characterized in that, in the means of claim 1, the grip for the patient to hold is attached to the tip of the backrest portion in order to maintain the posture of the patient under examination. To do.

  According to a fourth aspect of the present invention, in the above-mentioned means of the first aspect, the right lower leg receiving portion as viewed from the backrest portion is integrally formed with a bulging portion for an examiner to sit on. Features.

  As described above, the present invention is configured such that the chest support base is moved up and down in a substantially horizontal state when viewed from the undulating backrest, and the handle for moving the chest support base up and down is on the right side. Since the doctor operates the probe on the right side of the patient in the sleeping state and the handle can be operated on the right side to raise the chest support after the examination is completed, the chest support platform can be moved up and down. This can be done without moving to the left.

  In addition, by attaching a grip to the tip of the backrest, when the patient is inspected in the left-side-down position, the patient can hold the stable posture by holding the grip, and the inspection can be performed smoothly. .

  Furthermore, the right lower limb receiving part as seen from the backrest part is formed with a bulging part for an inspector to sit on, so that the inspector can be placed in an unreasonable posture by sitting on the bulging part and performing an inspection. There is an effect that the burden on the inspector can be reduced even in a long-time inspection without being forced.

  The present invention detachably forms a chest support placed on a part of the backrest on the left side when viewed from the backrest side of the medical table from the backrest side, on the opposite side of the chest support. A handle is attached to the back side of the backrest, and the chest support is moved downward by operating the handle.

Hereinafter, an embodiment of a cardiac ultrasound examination table according to the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a base, and lifting means (not shown) such as a hydraulic cylinder is accommodated in a bellows-like shrinkable cover 11. Reference numeral 2 denotes a medical table comprising a lower limb receiving part 21 attached to the upper end of the elevating means and a backrest part 23 attached to the lower limb receiving part 21 via a rotating member 22.

  A hydraulic cylinder 24 is attached between the backrest portion 23 and the lower limb receiving portion 21, and the backrest portion 23 is rotated in the standing direction by supplying oil to the hydraulic cylinder 24. By pulling out, it is rotated in the prone direction. A U-shaped grip 25 is attached to the tip of the backrest 23. On the other hand, an arcuate bulged portion 21a is integrally formed on the right side (upper side in FIG. 2) of the lower limb support 21 in the longitudinal direction.

  The patient sleeps in a supine state with the lower limb from the waist on the lower limb receiving part 21 side and the back side on the backrest part 23 side with respect to the treatment table 2 configured in this way. In this state, the examiner sits on the bulging portion 21a of the lower limb receiving portion 21 and makes a diagnosis by placing the probe of the ultrasonic medical device around the chest of the patient.

  By the way, when the patient is inspected by the probe in a side position with the left side down on the medical table 2, the backrest 23 becomes an obstacle. Therefore, in the present invention, a recess 23a is formed on the left side in the longitudinal direction of the backrest 23 (lower side in FIG. 2), and the chest support 26 having a size that fits into the recess 23a is provided as the backrest 2. The chest support 26 is moved up and down in a substantially horizontal state by rotating the handle 31 of the up-and-down moving means 3 attached to the right side of the patient, and between the patient's heart and the backrest 23 in the prone position. A gap was created so that the probe could be inspected from this gap.

  Next, the details of the vertical movement means 3 will be described. As shown in FIG. 3, a handle 31 is pivotally supported on the back surface of the backrest 23 opposite to the recess 23a. Is pivoted to support one end of a moving link 32 that moves in the horizontal direction, and the other end of the moving link 32 is connected to a first parallel link 34 fixed via a connecting plate 33. Further, one end pivotally supports the second parallel link 35 on the back side of the backrest portion 23, and the other end of the second parallel link 35 and the other end of the first link 34 are the above-described chest support. 26 is pivotally supported on a hanging plate 26a projecting from the back side of 26.

In the above-described configuration, an operation in the case of performing an examination by applying a probe from the lower side of a patient who is in a lateral position with the left side down will be described.
That is, the operation of lowering the chest support 23 from the state in which the chest support 26 shown in FIGS. 1 to 3 is raised in the recess 23a of the backrest 23 and the backrest 23 is flat will be described.

  First, when an inspector or the like turns the handle 31 in the vertical movement means 3 counterclockwise, the moving link 32 moves to the left as shown in FIG. 6 from the position of FIG. When the moving link 32 moves in the left direction, a force that moves in the left direction via the connecting plate 33 acts on the first parallel link 34 fixed to the moving link 32. Since one end of the two parallel links 35 is pivotally supported on the back surface of the backrest 23, the other end pivotally supported on the chest support base 26 side is rotated counterclockwise.

  When the first parallel link 34 is rotated counterclockwise, the chest support 26 moves downward, and the other end of the second parallel link 34 is pivotally supported on the chest support 26. Therefore, the chest support 26 is lowered in a horizontal state without being inclined. The lowering of the chest support 26 is impossible when the parallel movement between the first and second parallel links 24 and 25 becomes impossible, and further lowering is prevented, so the handle 31 is rotated. Can not be done.

  As described above, the handle 31 for moving the chest support table 26 up and down is provided on the opposite side of the chest support table 26, so the left side (chest support table side) of the diagnosis table 2 is placed on the wall surface of the clinic. It becomes possible to arrange | position along.

  In the above-described embodiment, the case where the chest support 26 is moved up and down by rotating the handle 31 has been described. However, the rack is suspended on the back side of the chest support 26 and the worm gear meshing with the rack is attached to the handle. The above-described effects can be obtained even with a structure in which the rack is moved up and down by rotating the rack.
