The specific embodiment
The preferred embodiments of the present invention are described below with reference to the accompanying drawings.Fig. 1 to 4 is the perspective views that show the outward appearance of diagnostic ultrasound equipment 10 according to a preferred embodiment of the invention.Fig. 1 is a front-side perspective view, and Fig. 2 is a backside perspective view, and Fig. 3 is the front-side perspective view that display operating panel is stored state, and Fig. 4 shows that probe bracket is removed the front-side perspective view of state.
On the leading flank of guidance panel 14, be provided with executive component (keyboard that for example is used for characters such as input alphabet or numeral), be used to select and regulate slide switch, button class switch, graduated disc and the tracking ball of the various functions of ultrasonic diagnosis.Operate diagnostic ultrasound equipment 10 by the operating operation element.As shown in Figure 3, on the rear surface of guidance panel 14, promptly when main body 12 and guidance panel 14 are closed on the surface in the outside, be provided with luminescence unit 30.Luminescence unit 30 comprises and embeds the front panel be installed in the guidance panel 14, and by being positioned at transparent, the translucent or opaque material after the front panel and making such as the light source of LED.Can on the pro-panel shading light part be set,, can also form predefined character, picture etc. suitably to cover light from light source.When the power supply of diagnostic ultrasound equipment 10 is in the ON state, light source luminescent, when the power supply of diagnostic ultrasound equipment 10 was in the OFF state, light source extinguished.In this way, luminescence unit 30 plays the function of the indicator of the ON/OFF state of indicating power supply.Utilize this configuration,, can know that also power supply is in the ON state, as shown in Figure 3, thereby guarantee power supply is switched to the OFF state even under guidance panel 14 closing state.
Connecting frame 16 comprises bottom 32 and arm 34, and bottom 32 allows devices to be placed on flat surface, and for example on the end face of desk, arm 34 32 extends upward from the bottom.Near the end of arm 34, be provided with the body supports piece 36 of pivotal support main body 12.Main body 12 can be rotated around central shaft pivot in predefined angular range of back-up block 36.By main body 12 pivots are rotated, main body 12 can recede in the pivot rotation, also can the pivot rotation turn forward.Ideally, pivotally supported scope is set, makes sweptback angle, i.e. the angle of inclination of display screen 15a up the time can be greater than the angle that turns forward.In diagnostic ultrasound equipment 10, main body 12 can turn forward 10 ° and recede 30 ° from the vertical position of display screen 15a.Because main body 12 can turn forward, can suppress the illumination reflection etc. on the display screen 15a.In addition, because when using diagnostic ultrasound equipment, the operator watches display screen 15a in the ultrasound probe contact object, so operator's viewpoint may become lower position.In this case, the configuration that allows display screen to turn forward is favourable.
Body supports piece 36 has the position supportive body of certain distance with the position than end portion near main body 12 in the direction that makes progress, and can the range of movement of main body 12 be narrowed down by the pivot rotation.But, if main body is supported on too high position, come pivot to rotate main body 12 even want to remain near position, main body upper end simultaneously by mobile agent, main body 12 can not be rotated by pivot.Therefore, ideally, the height of the position that main body 12 is supported is more than or equal to 1/4 of the height of main body 12, and be less than or equal to main body 12 height 1/2.
Near the root of the arm of connecting frame 16, be provided with the guidance panel back-up block 38 of pivotal support guidance panel 14.Guidance panel 14 rotates around the central shaft pivot of guidance panel back-up block 38.When guidance panel 14 is opened, the rear side of guidance panel back-up block 38 support panels.In this process, the front side of guidance panel 14 can be by surface support, for example the desktop and the estrade at connecting frame 16 places.Guidance panel 14 can rotate by pivot between the state of state shown in Fig. 1 or 4 and near vertical shown in Figure 3, and in Fig. 1 or Fig. 4, guidance panel 14 inclination forward is oblique, is provided with the front face of various executive components.The oblique state of guidance panel 14 inclination forward shown in Fig. 1 or 4 is called as " open mode " of diagnostic ultrasound equipment 10, and guidance panel 14 shown in Figure 3 is set to vertical position and is called as " store status " along main body 12 closing state.
In store status, main body 12 and guidance panel 14 are in the state of near vertical, wherein the surface of the main body 12 at display screen 15a place be provided with various executive components guidance panel 14 the surface toward each other.Diagnostic ultrasound equipment 10 can be placed on the plane with this direction, for example on the desktop.In store status, very little towards the raised zones of horizontal surface, so diagnostic ultrasound equipment 10 can be stored in the very narrow storage area.
As mentioned above, in diagnostic ultrasound equipment 10, can rotate main body by pivot and change direction with the display surface of the display unit of main body one.In addition because link can place in the plane, and main body and guidance panel in this state pivot rotate, therefore can handle assembly be set in the vertical store status of main body and guidance panel.In this store status, occupied area diminishes, and therefore device can be stored in narrower position.
Can also adopt 16 of connecting frames to be used for the configuration of mechanical connection main body 12 and guidance panel 14.In other words, cable or analog can be set, the signal of telecommunication, or rather, the signal relevant with operation of exchange between guidance panel 14 and the main body 12 is by described cable or analog transmission.This signal is by connecting the independent cable transmission of main body 12 and guidance panel 14, and the function of diagnostic ultrasound equipment passes through main body 12 and guidance panel 14 is realized, and need not connecting frame 16.
The support 40 that stores probe or analog can be arranged on the connecting frame 16.Support 40 shown in the figure comprises that gelling vessel receptor 44 holds the container that is applied to the gel on the object surface for matched impedance corresponding to the probe container 42 of two kinds of ultrasound probes and gelling vessel receptor 44.Because support 40 is arranged on the connecting frame 16, even when main body 12 and the rotation of guidance panel 14 pivots, support 40 does not also move, but can stably support ultrasound probe and gelling vessel.In addition, can also adopt the configuration that probe bracket is arranged on left side among the figure of main body 12.In addition, can also adopt this configuration, the support that promptly only has the ultrasound probe container is arranged on the right side, and the support of support gel rubber container is arranged on the left side.
Fig. 5-7 relates to the sketch map of the storage of power supply cable 46.The rear surface of main body 12 is provided with power supply cable container 48 (Fig. 2), and the pin that is electrically connected to power supply cable is placed on the power supply cable container 48.In addition, the rear surface is provided with a pair of cable winding projection 22 that stores power supply cable 46 by winding power supply cable 46.Cable winding projection 22 comprises from the cylindrical section 50 of the rear surface projection of main body 12 and is fixed on the vertical flange portion 52 of cylindrical section.Flange portion 52 extends to the outside from the top of cylindrical section 50, thereby the step that this structure forms supports the power supply cable of winding.On cylindrical section 50,, be provided with the groove 52 that clamps cable on top shown in Figure 5 near a side of power supply cable container 48.As shown in Figure 5, after power supply cable 46 was sandwiched in the groove, flange portion 52 was connected to cylindrical section 50, as shown in Figure 6.In this way, even unexpectedly pull out power supply cable, can prevent that also power supply cable 46 from unclamping from container 48.Twine on the projection 22 at the cable on the opposite flank, groove needn't be set.As shown in Figure 7, power supply cable 46 is wrapped in two cables and twines between the projection 22, and is stored.
In diagnostic ultrasound equipment 10, main body 12 and guidance panel 14 can rotate by pivot, and when carrying, diagnostic ultrasound equipment 10 can also advantageously obtain compact appearance.If just can be set to the position that is suitable for carrying to main body 12, then be easily by simple operations.In addition, when main body 12 and guidance panel 14 when all pivot rotates, the stability when carrying will reduce.Consider these problems, the diagnostic ultrasound equipment 10 of present embodiment has the mechanism that promotes handle 28, so that main body pivots to vertical state and main body is fixed in the vertical position.
Fig. 8 and 9 has shown the state when the open mode of diagnostic ultrasound equipment 10 becomes store status.In Fig. 8 and 9, in order to observe main body 12 and guidance panel 14 better, omitted the part of connecting frame 16, for example arm 34.
As mentioned above, the main body 12 of diagnostic ultrasound equipment 10 can be in predetermined angular range be that rotate at connecting frame 16 head lamp brush guard pivots at the center with body supports piece 36.Fig. 8 has shown that main body 12 backs tilt to the state of maximum angle (angle that recedes is 30 °).In this configuration, display screen 15a recedes 30 ° with respect to vertical direction.When guidance panel 14 when open position (position as shown in Figure 1) rises, the bezel assembly 90 on the front surface of guidance panel 14 (be provided with console switch etc. surface) contacts the housing parts 92 of low side of the main body that is close to approximate box-like forwardly in position shown in Figure 8.When further lifting with pivot rotating operation panel 14, guidance panel 14 promotes main body 12, so that main body 12 pivot in the direction that reduces its angle that recedes rotates.Fig. 9 has shown that the angle that recedes is 20 ° a state.When guidance panel 14 further pivoted to as shown in figure 10 vertical state, main body 12 also pivoted to the near vertical state.
Figure 11 has shown the main body 12 of Fig. 8 and near the amplifier section the contact point between the guidance panel 14.Contact point 94 places between the housing parts 92 of the bezel assembly 90 of guidance panel and main body are applied to power on the main body 12 and produce clockwise moment around the central shaft of body supports piece 36 by guidance panel.In other words, determine the shape of bezel assembly 90 and housing parts 92, bezel assembly 90 and housing parts 92 are contacted with each other in the position that produces this moment.Ideally, can determine the shape of parts, make contact point 94 be positioned at vertical surperficial 96 left side of the axis of Figure 11 by guidance panel back-up block 38.For this reason, in diagnostic ultrasound equipment 10, around housing parts 92 form inclined-plane 98 than downside, to produce fillet.
Figure 12 is the perspective view of a part that shows the internal structure of diagnostic ultrasound equipment 10.Similar with Fig. 8, Figure 10 has shown the state when main body backs tilt to maximum angle, does not wherein have display operating panel 14.Handle 28 is positioned on the upper surface of box-like of main body 12.Handle 28 comprises the upper surface portion 100 of extending along the whole width of the upper surface of main body and the side surface portion 102 that extends from two edges of upper surface portion along the side of main body, its approximate on the whole U-shaped downwards.When handle 28 operations, only allow to slide along the direction that side surface portion 102 extends.On the directly inside part in the side of main body, be provided with along the slide bar 104 that extends with the direction that vertically is complementary of the lateral parts 102 of handle.Slide bar 104 vertically is slidably along its.Slide bar 104 and handle 28 engages allowing the relative slip in the preset range, and the integral body when surpassing this scope is slided.Slide bar 104 is approximate L shaped sheet components, towards extending of main body than lower part, and than the rear surface one lateral bending song of lower part towards main body.At the end of L shaped horizontal component, be provided with driven protruding 106, its in the direction of passing the accompanying drawing paper towards the front side projection.
In addition, the side surface of main body inboard partly on, be provided with the guide plate 108 that is fixed on the connecting frame 16.As shown in figure 12, guide plate 108 is positioned at the front side of slide bar 104, and the setting of guide plate 108 and slide bar 104 can not interfere with each other these parts fully.But driven protruding 106 of slide bar is positioned at the plane that guide plate 108 is limited.Because driven protruding 106 and guide plate 108 between engagement relationship, the motion of slide bar 104 is limited.Holding driven protruding 106 gathering sill 110 is arranged on the guide plate 108.
Figure 13-15 has shown the relation between the relation between guide plate 108 and the slide bar 104, particularly guide plate 108 and driven protruding 106 in detail.Figure 13 has shown the state when main body 12 backs tilt to maximum angle.Figure 14 has shown the state when main body 12 is in basic vertical position, has also shown driven protruding 106 states that insert slightly in the gathering sill 110.Figure 16 has shown the side view of diagnostic ultrasound equipment 10 under this state.Figure 15 has shown the state when main body 12 is in vertical position and handle 28 and is thus lifted to maximum height.Figure 17 has shown the side view of diagnostic ultrasound equipment 10 under this state.
Open in the downward in the drawings direction of the gathering sill 110 of guide plate 108, and as mentioned above, in this opening, hold driven protruding 106.Gathering sill 110 has the vertical curve 112 symmetric shapes with respect to the axis that passes through body supports piece 36, and broadens towards opening.The angle of for example, widening is each 5 ° and to the right left.Two sides of driven protruding 106 opening are provided with limit 114, and every limit 114 all is that the axis with body supports piece 36 is the circular arc at center, and 114 end is provided with block 116 and 118 on the limit.Driven protruding 106 by 114 restrictions of arcual limit, can not be moved beyond limit 114 in the direction that makes progress.In addition, driven protruding 106 also by block 116 and 118 restrictions, can not be along the limit 114 direction move.For example, pivotally supported direction can reach 30 ° in block 116 1 sides, can reach 10 ° in block 118 1 sides.This scope defines the pivot slewing area of main body 12, and corresponding to 30 ° recede and 10 ° turn forward.
When diagnostic ultrasound equipment 10 was carried, if main body 12 tilts, main body 12 and guidance panel 14 all were set to vertical state.As previously mentioned, when guidance panel 14 vertically the time, main body 12 also is vertical.But it also is possible having only main body to keep vertically.At first, handle 28 is raised from the state of receding of Figure 12.In this process, because driven protruding 106 move by the limit 114 of guide plate 108 limits, the slip of slide bar 104 is hindered.Therefore, handle 28 moves in above-mentioned scope, allow in this scope with respect to the relatively moving of slide bar 104, and the upper surface portion 100 of handle 28 is slightly away from main body 12.If finger is placed on the handle 28 and handle 28 further is raised in vertical direction, then main body 12 is upright, driven protruding 106 move to gathering sill 110 along the limit 114 positions of opening.In this position, driven protruding 106 do not engage with limit 114, allow the slip of slide bar 104.
Figure 14 has shown that slide bar 104 is moved the state that is inserted into gathering sill 110 with pulling handle 28 and driven protruding 106 under the effect of power.When handle 28 rose, driven protruding 106 deeper inserted in the gathering sill 110.Driven protruding 106 are directed to the side surfaces guiding of groove, and reach two side surfaces of driven protruding 106 and two side surface state of contact of gathering sill 110.Figure 15 has shown this state.In this process, main body 12 is set to vertical state, and is in the position of store status.In addition, because driven protruding 106 be directed to groove 110 restriction, the pivot rotary action of main body 12 is locked.In other words, when handle 28 was raised, main body 12 was set to and can not rotates by pivot.Therefore, carrying in the process that handle 28 is raised, main body 12 is locked, can not rotate with respect to connecting frame 16 and guidance panel 14 pivots.
Described above when the operation of main body 12 when the state of receding is raised.The operation of mentioning main body from the state of turning forward similarly.
When diagnostic ultrasound equipment 10 was set to store status, executive agent 12 was with respect to the pivot rotation of guidance panel 14 and the lifting of handle 28 simultaneously.In other words, in this configuration, the operation that promotes guidance panel 14 makes main body 12 rise to the approaching vertically state of state, further promotes handle 28, and main body 12 just is set to vertical state and is locked in this state.Ideally, be operated in the state that panel 14 mentions in main body 12, driven protruding 106 are in the position relative with the opening of gathering sill 110.By this structure, when handle 28 was raised, driven protruding 106 can be inserted in the gathering sill 110 immediately.
Because the weight of guidance panel 14 self, when opening or closing guidance panel 14, guidance panel 14 can rotate by pivot in the direction of opening operation panel 14, and ideally, this pivotally supported speed is not too big.But, if rotating, the pivot that gravity causes hindered by frictional force, open or close guidance panel 14 required power and may become big.In the diagnostic ultrasound equipment 10 of present embodiment, the pivot that causes for the weight that suppresses guidance panel 14 rotates, the inhibition combination of the inhibition of frictional force generation and elastic force generation.
Figure 18 has shown the mechanism (below be called moment of torsion applying mechanism 54) that applies moment of torsion to guidance panel 14 in detail, and it is included in the guidance panel back-up block 38.For the internal structure of display operating panel 14, do not show the panel component on the leading flank among Figure 18, but shown the panel component 56 on the trailing flank (below be called trailing flank plate member 56).
Moment of torsion applying mechanism 54 comprise the hinge axis 58 that is fixed on the connecting frame 16, to hinge axis 58 apply the friction sleeve 60 of friction torque and be arranged on hinge axis 58 and guidance panel 14 between torsionspring 62.Hinge axis 58 rotation is supported on two the locational ribs 64 and 66 that are arranged on guidance panel 14.Though Figure 18 has only shown ribs 64 and 66 and has been arranged on the part on the trailing flank plate member 56 that ribs also is arranged on the panel component of leading flank, and is relative with ribs shown in Figure 180, and hinge axis 58 supports by supported rib clamping.Hinge axis 58 comprises part that friction sleeve 60 and torsionspring 62 pass and the diameter major diameter part 68 greater than these parts.Depression 70 is formed on the outer surface of major diameter part 68.
Figure 10 and Figure 19-22 is used for explaining when guidance panel 14 opens or closes, acts on the moment of torsion on the guidance panel 14.Figure 10,19 and 20 is side views of diagnostic ultrasound equipment 10.Figure 10 has shown that guidance panel 14 vertically and the store status relative with main body 12.Figure 19 has shown that guidance panel 14 pivots to the state of angle θ from store status, and Figure 20 shown that guidance panel 14 pivots to open mode, promptly uses the state of state.Figure 21 A, 21B and 21C relate to have the sketch map of effect of the torsionspring 62 of first end 80 and the second end 82.Figure 22 has shown the moment of torsion that acts on the guidance panel 14.
Shown in Figure 10,19 and 20, guidance panel 14 can rotate by pivot between vertical store status (θ=0 °) and open mode (θ=100 °).In diagnostic ultrasound equipment 10, by guidance panel 14 is set to store status, and on the other hand, in use guidance panel 14 is set to open mode, improved the portability of device.When pivot rotating operation panel 14 opens it, because the weight of guidance panel 14 self has produced the moment of torsion in the opening operation panel direction of guidance panel back-up block 38.When the moment of torsion that causes when weight was big, it is big that the pivot velocity of rotation of guidance panel 14 becomes, therefore may occur when guidance panel contact diagnostic ultrasound equipment 10 places surperficial, and when opening procedure finishes, the situation that the impact change is big.The relative moment of torsion of moment of torsion in the direction of the opening operation panel that 54 generations of moment of torsion applying mechanism and the weight of guidance panel 14 of the diagnostic ultrasound equipment 10 of present embodiment produces.
Figure 21 A-21C has shown when the guidance panel pivot rotates, the relation between torsionspring 62 and the hinge axis 58.Figure 21 A is corresponding to the state of Figure 10, and Figure 21 B is corresponding to the state of Figure 19, and Figure 21 C is corresponding to the state of Figure 20.As mentioned above, the first end 80 of torsionspring is contained in the depression 70 of major diameter part.Depression 70 first end face 86 and second end faces 88 that comprise in the circumferencial direction, and first end 80 can move between first end face 86 and second end face 88.In other words, hinge axis 58 and torsionspring 62 are engaged with each other corresponding to the gap that moves through that is allowed.
When guidance panel 14 is in the store status, i.e. state shown in Figure 21 A, first end 80 is positioned at first end face, 86 1 sides.Though Figure 21 A shows first end 80 contacts first end face 86, torsionspring 62 is in free state, promptly is in the state that moment of torsion does not act on.Therefore, under store status, the first end 80 of torsionspring needn't contact first end face 86 of depression.
When guidance panel 14 pivots rotated, the second end 82 that is fixed on the torsionspring on the guidance panel by fish plate 84 was rotated, shown in Figure 21 B.By this effect, whole torsionspring 62 is rotated, and first end 80 moves to the other end 88 of depression.After the gap was by this mobile occupying, torsionspring 62 was operated the pivot rotation of panel 14 and reverses, and is producing as counteractive moment of torsion in the direction of shutoff operation panel 14 on the guidance panel 14.In this way, between the interstice coverage of torsionspring 62 and elastic force are with the scope that works, define boundary by first end 80, the second end faces 88 that engage and stop torsionspring.
In this way, reason owing to the gap, in the opening operation process of guidance panel 14, in the pivotally supported starting stage, torsionspring 62 does not produce moment of torsion, after this gap is occupied, in direction, produce moment of torsion corresponding to the shutoff operation panel 14 of the pivot angle of rotation θ of the guidance panel between Figure 21 B and the 21C 14.In other words, after the gap was occupied, the moment of torsion opposing that torsionspring 62 produces was by the moment of torsion of the weight generation of guidance panel 14.
Figure 22 has shown the moment of torsion that acts on the guidance panel 14.The moment of torsion that is produced by the weight of guidance panel 14 shows with dotted line, and the moment of torsion (hereinafter referred to as the moment of resistance) of the weight of the opposing guidance panel that is produced by moment of torsion applying mechanism 54 or analog is represented with solid line.In Figure 22, some a, b and c correspond respectively to Figure 21 A, 21B and 21C.
The moment of resistance among the a-b is produced by the friction torque of friction sleeve 60 and the friction torque of other slide units at interval.Friction torque is constant with respect to the pivot angle of rotation θ of guidance panel.When pivot angle of rotation θ increased, this friction torque was not enough to resist the moment of torsion that the weight of guidance panel produces.The torsional interaction that torsionspring 62 produces is in the b-c of interval, and the moment of torsion that the elastic force of torsionspring 62 produces is added in the above-mentioned friction torque, and the two is jointly as the moment of resistance.In the present embodiment, the moment of resistance that produces of the elastic force point b that begins to work is set to the point that the moment of torsion of the moment of resistance that frictional force produces and weight generation is complementary.In addition, at the point (some c) that guidance panel 14 is opened fully, the value of the moment of resistance also is set to mate the moment of torsion that is produced by weight.The position of second end face 88 of the depression by regulating the major diameter part and the spring constant of torsionspring are realized this set.
Determine the setting of the point (some b) that the moment of resistance that elastic force produces begins to work, the moment of torsion that frictional force produces in the a-b of interval can not become greatly, and the moment of torsion and the difference between the moment of resistance of weight generation in the b-c of interval can not become big.If friction torque is bigger in the a-b of interval, the operator needs bigger power ability pivot rotating operation panel 14.In addition, if differing greatly between the moment of torsion that weight produces in the b-c of interval and the moment of resistance, guidance panel may rotate by pivot in the direction of just closing under the state that the operator does not operate or opening.In a word, ideally, the pivot angle of rotation θ of guidance panel is set to 40 ° to 50 ° scope.In the present embodiment, θ is set to 48 °.
Point b and c do not need to be present on the curve of representing with dotted line (moment of torsion that weight produces) among Figure 22.If the maximum difference δ between the curve that line segment b-c and dotted line show is no more than the difference between the moment of torsion that moment of torsion that the stiction among the b-c at interval produces and kinetic force of friction produce, guidance panel 14 can keep resting state on any angular position in this interval.Therefore, can set-point b and c satisfy this condition.
As mentioned above, the diagnostic ultrasound equipment 10 of configuration present embodiment makes when guidance panel 14 is opened, and in the starting stage, the moment of torsion that has only frictional force to produce works, and the moment of torsion of elastic force generation just works then.By this configuration, can reduce the required power of opening operation initial stage opening operation, simultaneously, even when the moment of torsion that produces in the weight of guidance panel 14 becomes big, also can suppress panel that moment of torsion that this weight produces causes do not expect move.
