Ultrasonic diagnostic apparatus

Abstract

To suppress turning of a monitor part in a closed position in an ultrasonic diagnostic apparatus having the monitor part that can turn with respect to an apparatus body.SOLUTION: A monitor part 18 can be opened and closed with respect to an apparatus body 16, and can turn around a turning axis R. The monitor part 18 is energized toward a closed position in the vicinity of the closed position. The turning axis R is inclined backward with respect to a direction perpendicular to an operation panel 20 on the top face of the apparatus body 16. When the monitor part 18 in the closed position turns around the turning axis R inclined backward, the trajectory T of a point P on the monitor part 18 interferes with the apparatus body 16. By the interference of the monitor part 18 with the apparatus body 16 by the turning, the turning of the monitor part 18 in the closed position is suppressed.SELECTED DRAWING: Figure 10

[0013] An embodiment of the present invention will be described below with reference to the drawings. 1 shows the front side and FIG. 2 shows the rear side. The ultrasonic diagnostic device 10 includes a device main body 16 having a flat, approximately rectangular parallelepiped shape, and a device main body The monitor 18 has a flat plate shape and is supported at the rear edge of the monitor 16. As shown in FIG. When the section 18 is placed on the device body 16, the shape of the ultrasonic diagnostic device 10 becomes the same as the whole. From this state, the monitor unit 18 is rotated to assume an upright position as shown in FIG. The ultrasonic diagnostic device 10 is used as a diagnostic device for ultrasound. The device main body 16 processes the transmitted and received ultrasonic signals. The circuitry includes a display circuit, a power supply circuit, a battery, a memory device, etc. The top surface of the device body 16 is equipped with a pointing device such as a trackball or a trackpad. An operation panel 20 having a touch panel and buttons for operation is provided. The monitor unit 18 has a display 22 arranged thereon.

[0014] The cart 14 has legs 26 each having four casters 24 and a column-like support member 26. The columnar portion 28 includes a mounting base 30 fixed to the upper end of the columnar portion 28. A cart handle 34 is provided around the entire circumference of the diagnostic device 10 mounting table 30. It is being done.

[0015] The ultrasound diagnostic device 10 can be transported while installed on a cart 14. It can also be removed from the port 14 and transported independently.

[0016] 3 to 5 are diagrams showing the ultrasonic diagnostic device 10 alone. In this diagram, the arrow FR points forward, the arrow UP points upward, and the arrow LH points left. FIG. 3 is a perspective view showing the monitor unit 18 in an open state. The monitor unit 18 is attached to the device main body 16. 4 is a side view showing the monitor unit 18 in an open state. FIG. 2 is a rear view showing the monitor unit 18 in a closed state.

[0017] When the ultrasound diagnostic device 10 is placed on a horizontal surface, the operation panel 20 is also placed horizontally. 18 is supported by a hinge member 36 at the rear edge of the device body 16. The member 36 supports the monitor unit 18 so that the monitor unit 18 can rotate about the rotation axis R. The ultrasonic diagnostic device is also supported so as to be rotatable about an opening / closing axis Q perpendicular to the direction in which the ultrasonic diagnostic device R extends. In the monitor unit 10, the rotation axis R and the opening / closing axis Q are perpendicular to each other. Rotation around the rotation axis R is referred to as rotation, and rotation around the opening / closing axis Q is referred to as opening / closing.

[0018] The rotation axis R is fixed to the device body 16, and is That is, it is tilted backward with respect to the direction perpendicular to the surface of the operation panel 20. This backward tilt angle α is The angle of reversion α may be 5° to 15°, and particularly 10°. When the station 10 is placed on the cart 14, the rotation axis R is set to extend vertically. As shown in FIG. 1, when the ultrasound diagnostic device 10 is placed on the cart 14, the operation panel The front edge of the panel 20, i.e., the edge closest to the operator, is inclined relative to the horizontal. The dashed line H in FIG. 1 indicates the horizontal, and the operation panel 20 is placed at an angle β. By making the rearward tilt angle α equal to the tilt angle β of the operation panel 20, the rotation axis R The opening / closing axis Q rotates together with the monitor unit 18, and the monitor unit 18 faces forward. When facing the screen, it is positioned horizontally, i.e., parallel to the surface of the operation panel 20.

[0019] 6 to 8 are views showing the hinge member 36, with FIG. 6 being a front view, FIG. 7 being a side view, and FIG. 8 being a plan view. The hinge member 36 is arranged along a central axis 38 and a direction perpendicular to the central axis 38. The shaft 38 and the hinge shaft 40 are integral and arranged in a roughly T-shape. The central portion of the hinge shaft 40 is connected to the upper end of the shaft 38. The base 16 is supported by a bracket 42 fixed to the base 16 so as to be rotatable about the axis of rotation R. Therefore, the center line of the shaft 38 coincides with the rotation axis R. The shaft 38 is supported by a flange 38a and a washer 38b. The connecting surface 42a of the main body bracket 42 is clamped and supported by the main body bracket 42. By tightening the nut 43 screwed to the lower end of the shaft 38, the washer 38b The biasing force acts through the stacked disc springs 44, and the biasing force causes the connecting surface 4 2a is clamped by the friction between the flange 38a and washer 38b and the connecting surface 42a. This maintains the position of the monitor unit 18 in the rotation direction.

[0020] The hinge shaft 40 is fixedly connected at its left and right ends to the monitor unit 18 via an L-shaped hinge shaft. The monitor bracket 46 is supported so as to be rotatable about the opening / closing axis Q. The left and right extending portions of the monitor unit 6 are fastened to the lower edge of the monitor unit 18 by fastening elements such as bolts. The hinge shaft 40 has a step 40a formed by reducing the diameter of the end portion. The step 40a and the washer 48 allow the cam follower washer 50 and the monitor bracket 4 The cam follower washer 50 is used to rotate the motor about the opening / closing axis Q. The monitor bracket 46 is integral with the monitor unit 18, and the rotation of the monitor bracket 46 is controlled by the opening and closing of the monitor unit 18. By tightening the nut 52 that is screwed onto the end of the hinge shaft 40, The washer 48 is biased by a plurality of stacked disc springs 54. The biasing force acts on the monitor bracket 46 from the left side, and the biasing force acts on the right monitor bracket 46 from the right side. The left and right pair of monitor brackets 46 are clamped by these biasing forces. The friction between the monitor bracket 46 and the disc spring 54 causes the monitor portion 18 to rotate. Resistance is provided to the opening and closing movement.

[0021] FIG. 9 shows the cam 56 and the cam follower washer 50 formed on the step 40a of the hinge shaft 40. 1(a) shows the monitor unit 18 in an open position, and FIG. b) shows the state when it is in the closed position. The step 40a of the hinge shaft has an end cam and As shown in the figure, the cam 56 has a slope 56a. The cam follower washer 50 also has a slope 50a formed on the surface facing the cam 56. .

[0022] The cam follower washer 50 rotates together with the monitor bracket 46, but the opening / closing axis Q In the direction along the arrows, the cam follower is movable independently from the monitor bracket 46. The washer 50 is biased toward the step 40a, that is, toward the right in FIG. This biasing force is applied to the cam follower washer 50 and the monitor block 40. This may be provided by a spring, such as a disc spring, provided between the rackets 46 .

[0023] When the monitor unit 18 is in the open position, the inclined surface 56a of the cam 56 and the cam follower washer 5 The inclined surfaces 50a of the monitor unit 18 are not opposed to each other as shown in (a). As shown in (b), the inclined surfaces 50a and 56a face each other.

[0024] When the monitor unit 18 rotates from the open position to the closed position, the slope of the cam follower washer When the cam follower washer 50a engages with a part of the cam slope 56a, the cam follower washer 50 acts on it. The biasing force of the monitor unit promotes rotation toward the closed position. When the monitor unit 18 approaches the closed position, a biasing force toward the closed position acts on the monitor unit 18. and the cam follower washer 50, and the cam follower washer 50 is biased toward the cam 56. The spring constitutes a biasing mechanism that biases the monitor unit 18 toward the closed position. The biasing force may act in the range of 5 to 15 degrees from the closed position, and preferably from the closed position. This biasing force may act in the range of 10° to 10°. Also, when the monitor unit 18 is away from the closed position, a biasing force is generated. You may refrain from using it.

[0025] FIG. 10 is an explanatory diagram of the rotation prevention of the monitor unit 18 in the closed position. When the monitor unit 18 rotates around the rotation axis R, the monitor Any point P on the rotor 18 is a circular arc with the axis of rotation R as its center in a plane perpendicular to the axis of rotation R. Since the rotation axis R is tilted backward, the locus T of point P interferes with the device body 16. Therefore, when the monitor unit 18 is in the closed position, it may come into contact with the device main body 16 if it is attempted to be rotated. In addition, the biasing force that directs the monitor unit 18 to the closed position is This prevents the monitor unit 18 from floating up when the monitor unit 8 tries to turn, and contributes to preventing the monitor unit 18 from turning.

[0026] When the ultrasonic diagnostic apparatus 10 is placed on the cart 14 and moved, the ultrasonic diagnostic apparatus 10 is When transporting the device, the monitor unit 18 may rotate in the closed position due to vibrations and shaking during transportation. This can prevent this from happening.

[0027] In order to prevent the monitor unit 18 from turning when it is in the closed position, the left and right edges of the operation panel 20 are Friction pads 58 (see FIG. 3) may be disposed on the surface of the suction pad 54. The friction pads 58 are made of a material having a coefficient of friction such as rubber. Furthermore, instead of or in addition to the operation panel 20, a monitor Friction pads may be provided near the left and right edges of the surface of the controller 18 that faces the operation panel 20.
