Abstract

The control panel and display of a cart-borne ultrasound system are support by a lift which can be controlled to allow the control panel and display to be raised, lowered, and rotated. The lift has a first pivot elbow mounted to the ultrasound system cart and a second pivot elbow on which the control panel and display are mounted. A four-bar linkage is coupled between the pivot elbows which enables to control panel and display to be raised and lowered while maintaining the inclination of the control panel. The pivot elbows allow the control panel and display to be turned and rotated. A pair of hydraulic struts are mounted to the four-bar linkage to support the weight of the control panel and display. When a control button on the handle of the control panel is depressed the control panel and display can be freely raised, lowered and rotated. When the control button is released the pivot elbows and four-bar linkages are locked in their current positions.

First claim

What is claimed is:

1. An ultrasound system comprising:
a cart housing comprising wheels;
a control panel;
a display;
a lift coupled to the cart housing, the control panel, and the display, wherein the lift is configured to articulate, to raise, lower and rotate the control panel and the display in relation to the cart housing, the lift further comprising an elevation mechanism configured to raise and lower the control panel and the display, the lift further comprising a hydraulic strut coupled to the elevation mechanism;
a control button disposed on the control panel and configured to be actuated by a user to allow the elevation mechanism to be raised and lowered and, when not actuated, causes the elevation mechanism to be locked in position; and
a switch that is configured to lock the lift in position when the wheels are locked, when the control panel is located in a straight-ahead position, or a combination thereof.

2. The system of claim 1 , further comprising a pivot elbow configured to rotate in relation to the control panel and the display.

3. The system of claim 2 , further comprising:
a first solenoid coupled to the pivot elbow; and
a second solenoid coupled to the hydraulic strut,
wherein the first and second solenoids are configured to be actuated by the control button to enable the pivot elbow to rotate and a piston of the hydraulic strut to extend or retract.

4. The system of claim 3 , wherein the pivot elbow is located at the bottom of the lift and is coupled to the cart housing; and further comprising a second pivot elbow located at the top of the lift and coupled to the control panel.

5. The system of claim 4 wherein the elevation mechanism further comprises a four-bar linkage coupled between the first and second pivot elbows, wherein the four-bar linkage operates to maintain a relative inclination between the first and second pivot elbows.

6. The system of claim 5 , wherein the hydraulic strut is a first hydraulic strut, the system further comprising a second hydraulic strut coupled to the four-bar linkage.

7. The system of claim 3 , wherein the cart housing further comprises a brake configured to be actuated by a user to lock the wheels.

8. The system of claim 7 , wherein, when the brake is not actuated, the pivot elbow and elevation mechanism are locked.

9. The system of claim 7 , wherein the switch is coupled in-line between the control button and the first and second solenoids.

10. The system of claim 9 , wherein, when the brake locks the wheels, the switch is closed to allow the first and second solenoids to be energized by the control button.

11. The system of claim 7 , wherein the pivot elbow comprises the switch, which is coupled to the brake.

12. The system of claim 11 , wherein the switch is configured to determine when the control panel is located in a straight-ahead position, and wherein the brake cannot be operated to unlock the wheels unless the control panel is determined to be in the straight-ahead position.

13. The system of claim 12 , wherein the pivot elbow further comprises a detent which is engaged when the control panel is oriented in the straight-ahead position.

14. The system of claim 2 , wherein the pivot elbow further comprises gear teeth, and a solenoid actuated pin which engages the gear teeth to prevent rotation of the pivot elbow.

15. The system of claim 1 , wherein the control panel comprises a handle and the control button is located on the handle.

16. The system of claim 1 , wherein the control panel further comprises a control panel assembly to which the display is mounted.

17. The system of claim 1 , wherein the system is configured such that the control panel can be articulated by the lift to be oriented in a straight-ahead position.

18. The system of claim 1 , wherein the control button comprises a lighted switch.
