  Hereinafter, an embodiment of a portable ultrasonic diagnostic apparatus to which the present invention is applied will be described in detail with reference to the drawings.

<First embodiment>
FIG. 1 is a diagram showing the entire portable ultrasonic diagnostic apparatus to which the present invention is applied. This ultrasonic diagnostic apparatus includes a main body 1 in which an electronic circuit necessary for ultrasonic examination is housed, and a display case that is connected to the main body 1 and includes a display that displays images processed by the main body 1. 2, an operation casing 3 including an operation console for inputting information necessary for the operation of the main body 1, and a transport belt (hereinafter also simply referred to as a belt) 4. Parts such as a probe necessary for ultrasonic inspection are separately carried in a portable state. In the following description, the belt 4 and other components are separated as necessary, and the main body 1, the display housing 2, and the operation housing 3 are collectively referred to as the apparatus main body or the apparatus side.

  The main unit 1 is the same as a general ultrasonic diagnostic apparatus, and includes an ultrasonic transmission / reception circuit, a signal processing circuit, an arithmetic circuit, a control circuit, etc., and is connected to a power source (not shown). The terminal part for doing is provided in the side surface.

  The display housing 2 and the operation housing 3 are each pivotally supported so as to be independently rotatable at one end of the main body 1 and can be rotated with respect to the main body around each axis. In the illustrated embodiment, the display housing 2 is pivotally supported at the center of the side surface of the main body 1 and the operation housing 3 is pivotally supported at two locations on both sides thereof. In addition, the bearing of the display housing 2 is fixed so as to be able to turn with respect to the main body 1, whereby both the rotation and the turning with respect to the main body 1 are possible.

  In addition, the display housing 2 and the operation housing 3 are each a rectangular parallelepiped with a small thickness, and the size of the main plane (the surface with the largest area) is substantially equal, It can be carried and stored, and a mechanism (not shown) for locking the stacked state is provided. A mounting structure for fixing a belt 4 to be described later is provided on the side surface of the casing having a larger thickness, in this embodiment, the operation casing 3.

  The belt 4 is provided with a handle portion 41 at a substantially central portion in the longitudinal direction so that a person can easily put it on his shoulder or on his / her arm, and a pair of metal fittings 42 for adjusting the length is attached. ing. Hook fixtures 51 and 52 for attaching the belt 4 to the apparatus are fixed to both ends of the belt 4. Since the hook fixtures 51 and 52 have the same structure, the following description will be given as the hook fixture 5 in which both are combined unless otherwise distinguished.

  Next, an attachment structure formed on the end portion of the belt 4 and the side surface of the operation housing 3 will be described with reference to FIGS. 2 and 3.

  2A and 2B are diagrams showing details of the hook fixture 5 which is the attachment structure on the belt 4 side, wherein FIG. 2A is a perspective view and FIG. 2B is a side view. As shown in FIG. 2A, the hook fixture 5 is a member in which a hole 50 for passing the belt 4 is formed, and a hook 7 that engages with the mounting structure on the apparatus side is integrally formed. . The hook 7 has a small-diameter cylindrical portion 72 having a small diameter continuous with the hook fixture 5 and a large-diameter cylindrical portion 71 having a large diameter continuous therewith. The end surface of the large-diameter cylindrical portion 71 is substantially circular, and a long groove (concave portion) 73 having one end opened on the circumferential side is formed on the end surface. The long groove 73 constitutes an element on the hook side (belt side) of a later-described dropout prevention mechanism, and its function will be described in detail later.

  On the other hand, the side surface (both sides) of the operation housing 3 is formed with a hole 6 in which holes 61 and 62 having different diameters are continuous as shown in FIG. The position of the hole 6 is preferably above the center of gravity of the entire apparatus. In the embodiment shown in FIG. 1, the hole 6 is provided on the side farther from the connecting portion with the main body 1 than the center of the side surface of the operation housing 3. ing. Thereby, a stable structure can be taken when the apparatus is suspended by the belt 4. Further, since the main body 1 is on the lower side, when the apparatus is installed on the table for inspection or the like, the main body 1 can be first placed on the table and easy to install.

  The larger-diameter portion 61 having the larger diameter serves as an attaching / detaching position (first position) when the hook 7 is attached to and detached from the hole 6, and the diameter is slightly larger than the diameter of the large-diameter cylindrical portion 71 of the hook 7. Is formed. The small diameter portion 62 serves as a locking position (second position) of the hook 7, and has a diameter smaller than the diameter of the large diameter cylindrical portion 71 of the hook 7 and slightly larger than the diameter of the small diameter cylindrical portion 72. Thereby, in a state where the large-diameter cylindrical portion 71 of the hook 7 is inserted, the small-diameter cylindrical portion 72 located on the side surface of the hole 6 can be moved from the large-diameter portion 61 of the hole 6 to the small-diameter portion 62 side. The hook 7 (large-diameter cylindrical portion 71) cannot be removed from the hole 6 at the position on the portion 62 side. At the position where the hook 7 is moved to the small diameter portion 62 side, the hook 7 and the hook fixture 5 to which the hook 7 is fixed are rotatable, so that the main body can be moved up and down and carried at an arbitrary angle of the belt 4. .

  In normal carrying, the hook 7 does not come off because the hook 7 is held in the locking position on the small diameter portion 62 side by the weight of the main body, but the hook 7 is positioned at the large diameter of the hole 6 by some external force. When moved to the portion 61, the hook 7 is easily detached from the hole 6. For this reason, in the present embodiment, the hook 7 is detached by the engagement of the hook 7 and the apparatus side only when the hook 7 is at the position of the large-diameter portion 61 of the hole 6, that is, at the attachment / detachment position of the hook 7. Provide a mechanism to prevent.

  Hereinafter, the dropout prevention mechanism will be described in detail with reference to FIGS. 4 and 5. FIG. 4 is a perspective view showing a hook receiving member 8 which is a mechanism for preventing the apparatus from falling off, and FIG. 5 is a view showing a state in which the hook receiving member 8 is attached to the apparatus (here, the side surface of the operation housing 3).

  As shown in FIG. 4, the hook receiving member 8 is a substantially rectangular parallelepiped member having a space 80 in which the large-diameter cylindrical portion 71 of the hook 7 slides and having one surface opened. The operation casing 3 is fixed inside the side surface 31 so as to face the hole 6 formed in the side surface 31 of the operation casing 3. For fixing to the operation casing 3, a plate-like member 83 is formed on the hook receiving member 8 on the side opposite to the opened surface (referred to as the back surface 8 a). The hook receiving member 8 is formed of a moldable material such as plastic, and the plate-like member 83 and a rectangular parallelepiped portion can be integrally formed. Further, a notch 8c for adjusting the rigidity of the member 8 is provided between the side surface 8b and the back surface 8a where the plate-like member 83 is not formed. However, in this embodiment, this notch 8c is not essential.

  The space 80 inside the hook receiving member 8 is an elongated space that allows the large-diameter cylindrical portion 71 of the hook 7 to slide in the direction indicated by the thick arrow, and an elongated convex portion 81 is formed on the portion of the back surface 8a that faces the space. Has been. The convex portion 81 has a shape that engages with the long groove 73 formed in the large-diameter cylindrical portion 71 of the hook 7 described above, and is convex at a position facing the end portion of the space 80, that is, the large-diameter portion 61 of the hole 6. The portion 81 is formed so that the longitudinal direction thereof coincides with the longitudinal direction of the space 80. When the large-diameter cylindrical portion 71 of the hook 7 is inserted from the large-diameter portion 61 of the hole 6 so that the open end of the long groove 73 is on the lower side (that is, in the state shown in FIG. 2), the long groove 73 has the convex portion 81. The large-diameter cylindrical portion 71 is allowed to move along the longitudinal direction of the convex portion 81 in a direction away from the convex portion 81 (upward in the figure). On the other hand, when the small-diameter cylindrical portion 72 of the hook 7 slides in the space 80 after the hook 7 is hung on the hole 6, the hook 7 is appropriately rotated according to the use state. The hook 7 cannot return to the attachment / detachment position except for the position where the longitudinal directions of 81 coincide.

  In the hook 7 of the hook fixture 5 shown in FIG. 2, the long groove 73 of the hook 7 is in the vertical direction when the apparatus is suspended by the belt 4 in the longitudinal direction (when the belt 4 is parallel to the side surface of the operation housing 3. The longitudinal direction of the long groove 73 does not need to be parallel to the longitudinal direction of the belt described above, for example, As shown in FIGS. 6A and 6B, it may be tilted as appropriate or may be open in the opposite direction. In this case, when the hook 7 is inserted into the hole 6 and the belt 4 is attached to the apparatus, the hook fixture 5 is tilted or inverted by a predetermined angle, so that the long groove 73 and the convex portion 81 of the hook receiving member 8 are obtained. The hook 7 is inserted from the large-diameter portion 61 of the hole 6 in a state of engaging with each other, and is slid to the small-diameter portion 62 side and rotated to an arbitrary angle.

Next, the operation of attaching and detaching the belt will be described with reference to FIGS.
First, when attaching the belt 4 to the apparatus side, the hook 4 is fixed to the end of the belt 4 so that the direction of the long groove 73 of the hook 7 matches the direction of the convex portion 81 of the hook receiving member 8. The large-diameter cylindrical portion 71 of the hook 7 is put into the large-diameter portion 61 of the hole 6. At this time, the long groove 73 and the convex part 81 engage (state of FIG. 7). Next, the hook fixture 5 is moved along the hole 6 and the large-diameter cylindrical portion 71 is slid toward the small-diameter portion 62 side of the hole 6 (state shown in FIG. 8). In this position, the large-diameter cylindrical portion 71 having a diameter larger than that of the small-diameter portion 62 does not come out of the hole 6 even if a force in the direction of separating the hook fixture 5 from the hole 6 is applied. That is, the hook 7 does not come off from the hole 6. Even when the belt 4 is lifted and the device is suspended, the large-diameter cylindrical portion 71 continues to be positioned on the small-diameter portion 62 side by the weight of the device, so that the problem of the belt 4 falling off does not occur. In this position, the hook 7 is in a state of being appropriately rotated according to the positional relationship between the belt 4 and the apparatus.

  Here, when the external force is applied to the connecting portion between the belt 4 and the device or the pressure is applied from the bottom of the device, a force in the direction in which the hook fixture 5 is lowered may be applied. However, the long groove 73 of the large-diameter cylindrical portion 71 is engaged with the convex portion 81 of the hook receiving member 8 except when the rotation position of the hook 7 is in the same straight line as the long groove 73 and the convex portion 81 of the hook receiving member 8. Therefore, the movement of the large-diameter cylindrical portion 71 (the portion other than the long groove 73) toward the large-diameter portion 61 side of the hole 6 is restricted by the convex portion 81. Therefore, the hook 7 is held at the position on the small diameter portion 62 side and does not come off the hole 6.

  When removing the belt 4 from the operation casing 3, hold the hook fixture 5 so that the direction of the long groove 73 of the hook 7 matches the direction of the convex portion 81 of the hook receiving member 8. 6, the long groove 73 is fitted to the convex portion 81, and the hook fixture 5 can be moved to the position of the large-diameter portion 61 of the hole 6, that is, the attach / detach position, so that it can be removed from the hole 6.

  When the direction of the long groove 73 of the hook 7 is along the side surface of the operation housing 3 as shown in FIG. 2, the belt 4 can be easily attached / detached if operated in a state along the side surface of the operation housing 3. The action can be performed. In addition, when the direction of the long groove 73 has an angle with the direction of the belt 4 as shown in FIG. 6 or is reversed, the tip of the hook fixture 5 is attached to the operation casing when performing the attaching / detaching operation. 3 is required to be rotated by a predetermined angle with respect to the longitudinal direction of the side surface of the third side. However, in the state of use as shown in FIG. Can be prevented.

  In the case of an emergency or when the device is not installed, it is necessary to use the portable ultrasonic diagnostic device suspended from the shoulder with the belt 4 or to check the image. Thus, the operation panel 3 and the display panel can be checked by unlocking the operation casing 3 and the display casing 2 and rotating only the display casing 2. Even during such an operation, the belt 4 does not come off from the operation casing 3, so that the operation can be performed with confidence.

  As described above, according to the portable ultrasonic diagnostic apparatus of the present embodiment, the hook 7 side and the hole side of the device with which the hook 7 is engaged are engaged with each other at the attaching / detaching position of the hook 7 and other than the attaching / detaching position. By forming a structure that does not engage at the position (the long groove 73 and the convex portion 81), it is possible to prevent the hook 7 from being detached after the attachment.

  In the embodiment shown in the drawings, a case is shown in which a long groove is formed on the hook 7 side and a convex portion is formed on the hook receiving member side, but conversely, a convex portion is formed on the hook 7 side and the hook receiving member side is formed. It is also possible to form a groove on which the convex portion slides, and this structure can also prevent the hook from falling off.

  In the above embodiment, the case where the belt mounting structure is provided on the operation housing of the portable ultrasonic diagnostic apparatus including the main body, the display housing, and the operation housing has been described. As long as the housing has a sufficient thickness and structural strength, it can be provided not only in the operation housing but also in the display housing or the main body.

  Further, the present invention is similarly applied to a notebook-type ultrasonic diagnostic apparatus in which the function of the main body is housed in the operation casing, and an ultrasonic diagnostic apparatus in which the display unit and the operation unit are detachable from the main body. be able to. Even in such a case, the installation position of the mounting structure can be appropriately determined in consideration of the support structure and form of each housing constituting the apparatus, operability, and the like.

The main features of this embodiment are summarized as follows.
An attachment structure for attaching the belt to the apparatus side has a hook (7) fixed to the end of the carrying belt, an opening provided in the main body and into which the hook is inserted, and a space in which the hook slides (80), and a hook receiving portion (8) for rotatably holding the hook at a locking position different from the hook attaching / detaching position. Each of the hook (7) and the hook receiving portion (7) A drop-off prevention mechanism comprising a concave portion (73) and a convex portion (81) that are provided on the contact surface and engage with each other at the hook attachment / detachment position.

  In particular, the recess (73) of the drop-off prevention mechanism is a groove having a long length with respect to the width, and the convex portion (81) has a shape that fits into the long groove, and the hook receiving portion (8) among the concave portion and the convex portion. The shape formed in (2) is that the longitudinal direction is formed along the sliding direction of the hook (7) in the hook receiving portion.

  In addition, the apparatus main body includes an operation casing (3) having an operation panel and a display panel, and a display casing (folding connected to the operation casing so that the display panel and the operation panel face each other) 2), and when the operation panel or the panel surface of the operation panel is a main plane, the mounting structure has a thickness in a direction orthogonal to the main plane of the operation casing (3) and the display casing (2). Is provided on the thicker side.

  The apparatus main body includes a main body (1) to which a probe is connected, and an operation housing (3) and a display housing (2) that are connected to the main body so as to be foldable. Is provided on the side of the operation panel when the operation panel is the main plane.

The operation housing (3) and the display housing (2) are respectively connected to the same end of the main body (1), and the mounting structure is such that when the housing is lifted by a transport belt, the main body ( 1) is provided at a lower position.
Further, the mounting structure is provided on both end portions of the belt and on both side surfaces of the operation casing (3).

<Second embodiment>
The present embodiment is characterized in that, in addition to the belt mounting structure of the first embodiment, a structure that provides resistance to movement is provided in a space where the belt end (hook) slides. Since other configurations are the same as those in the first embodiment, different structures will be mainly described. In the drawings for explaining the present embodiment, the same elements as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  Also in this embodiment, as shown in FIG. 2, the hook fixture 5 is fixed to the end of the belt 4, and the hook fixture 5 includes a hook 7 having a long groove 73 on the end surface, and FIG. 3. As shown in FIG. 4, the hole 6 is formed in the side surface 31 of the operation casing 3, and the hook receiving member having a space in which the hook 7 slides is fixed inside the hole 6 as in the first embodiment. It is. However, the hook receiving member of this embodiment has a narrowed portion formed in a space in which the hook 7 (the large diameter cylindrical portion 71) slides.

  FIG. 9 shows a hook receiving member 800 of this embodiment. As shown in the figure, the hook receiving member 800 is a substantially rectangular parallelepiped in which a plate-like member 83 for fixing to the apparatus housing is integrally formed and one surface is opened, like the hook receiving member 8 shown in FIG. A convex portion 81 that engages with the long groove 73 of the hook 7 is formed on the back surface 8 a facing the space 80 with a shape member. The hook receiving member 800 is formed of a flexible material such as plastic or rubber.

  The width W of the space 80 is formed wider than the diameter of the large-diameter cylindrical portion 71 in order to allow the large-diameter cylindrical portion 71 of the hook 7 to slide, but the large-diameter cylindrical portion of the hook 7 is formed at the center in the longitudinal direction. A narrowed portion 82 having a slightly narrower width than the diameter of 71 is formed. The narrowed portion 82 is formed by making the side surface 8b of the hook receiving member 800 thicker toward the inside. The movement of the hook 7 in the space 80 is restricted by the presence of the narrowed portion 82, but when a certain amount of force is applied, the side surface 8 b of the hook receiving member 8 in which the narrowed portion 82 is formed bends and the movement of the hook 7 is prevented. It becomes possible. In order to adjust the ease of bending of the side surface 8b of the hook receiving member 800, a notch 8c is provided between the side surface 8b and the back surface 8a. By making the length of the notch portion 8c appropriate, when the hook 7 is slid in the space 80, there is resistance when passing through the constriction portion 82, but it can be slid against resistance and vibrates. For example, the hook 7 can be prevented from passing through the narrowed portion 82.

  The hook receiving member 800 may be formed of a non-flexible material such as ceramics. In that case, a plate spring or the like can be fixed to the side surface of the hook receiving member to form the narrowed portion 82. Yes, the force when passing through the constricted portion 82 can be adjusted by the strength of the leaf spring.

A function at the time of attaching and detaching the belt 4 in this embodiment will be briefly described.
First, the hook fixture 5 is operated, the large-diameter cylindrical portion 71 of the hook 7 is inserted into the large-diameter portion 61 of the hole 6, and the long groove 73 and the convex portion 81 formed on the hook receiving member 800 are engaged. Then, the hook 7 is slid along the space 80. At this time, there is resistance when the large-diameter cylindrical portion 71 passes through the constricted portion 82, but by moving the hook fixture 5 against the resistance, the small diameter portion 62 side of the hole 6, that is, the locking position. Moving. In this state, the hook 7 is not detached from the hole 6, and if the hook 7 is rotated with respect to the direction of the long groove 73 during attachment / detachment, the large-diameter cylindrical portion 71 is attached / detached by the convex portion 81 formed in the space 80. Since the movement to the position is prevented, the hook 7 does not come out of the hole 6.

  Even if the long groove 73 of the hook 7 and the convex portion 81 of the hook receiving member 800 are positioned on the same straight line, the movement of the large diameter cylindrical portion 71 to the large diameter portion 61 is suppressed by the narrowed portion 82. Again, the hook 7 does not come off the hole 6.

  When the belt 4 is removed, the hook fixture 5 is moved to the attachment / detachment position side so that the orientation of the hook fixture 5 is aligned with the orientation of the longitudinal direction of the convex portion 81. At this time, there is resistance when the large-diameter cylindrical portion 71 passes through the constricted portion 82, but the side surface of the hook receiving member 800 on which the constricted portion 82 is formed by moving the hook fixture 5 against the resistance. Is bent, and the large-diameter cylindrical portion 71 can be moved to the large-diameter portion 62 side of the hole 6, that is, the attaching / detaching position.

  According to the present embodiment, by providing the narrowed portion that resists the movement of the hook 7 in the space in which the hook 7 slides, the drop-off can be more effectively prevented.

  The portable ultrasonic diagnostic apparatus of the present embodiment also has the same changes as in the first embodiment, that is, the hook and the hook receiving member are different in the side on which the long groove and the convex part are formed, and there are a plurality of ultrasonic diagnostic apparatuses. In the case of this case, it is possible to change the mounting position of the mounting structure and to apply to an ultrasonic diagnostic apparatus other than the type shown in FIG.

  Further, in the first and second embodiments described above, the embodiment in which the structure for attaching and detaching the belt to and from the apparatus is provided on both end portions of the belt and the both side surfaces of the apparatus corresponding thereto. The present invention can also be applied to a device in which the end of this is fixed to the device and only the other end is detachable, and such an ultrasonic diagnostic device is also included in the present invention.

The main features of this embodiment added to the features of the first embodiment are as follows.
The drop-off prevention mechanism further includes a resistance mechanism for restricting the sliding of the transport belt end portion (hook 7) in the slide mechanism. In particular, the slide mechanism has a space (80) for sliding the end portion (hook 7) of the transport belt from the first position (detachment position) to the second position (locking position). The narrow portion (82) formed between the first position and the second position of the space.
