Abstract

A hand switch for use with an x-ray machine includes a first switch actuator that starts the prepare sequence of the x-ray machine. Upon completion of the prepare sequence, the hand switch signals the x-ray technologist with a tactile indication that the prepare sequence checks are complete and that the machine is ready for an exposure. The hand switch has a second switch actuator that is used by the technologist to activate the exposure. During the actuation of the first and second switch actuators, the operator may maintain uninterrupted visual contact with the patient.

Claims

1. A hand switch for use by an operator of an x-ray machine which comprises

a housing,

a first switch actuator for activating a prepare sequence for the x-ray machine,

a second switch actuator for activating x-ray exposure by the x-ray machine, and

a tactile indicator for informing the operator that the prepare sequence has been completed and that the x-ray machine is ready to be activated for exposure.

2. The hand switch of claim 1 wherein the first switch actuator includes a depressible first switch button.

3. The hand switch of claim 1 wherein the second switch actuator includes a depressible second switch button.

4. The hand switch of claim 2 wherein the first switch button is spring loaded to urge the button outwardly of the housing.

5. The hand switch of claim 3 wherein second switch button is spring loaded to urge the button outwardly of the housing.

6. The hand switch of claim 1 wherein the first switch actuator is electrically connected to the x-ray machine to initiate the prepare sequence for the machine.

7. The hand switch of claim 6 wherein the tactile indicator is electrically connected to the x-ray machine to be activated upon completion of the prepare sequence.

8. The hand switch of claim 7 wherein the tactile indicator is a vibrating motor.

9. A hand switch for use with an x-ray machine, said machine having electrical circuitry for conducting a prepare sequence whereby various electrical circuits are checked for safety and operational status, which comprises

a prepare switch for activating the prepare sequence,

means for sensing completion of the prepare cycle,

means for actuating a tactile signal upon completion of the prepare sequence, and

an expose switch for activating x-ray exposure by the machine.

10. The hand switch of claim 9 including a housing wherein the prepare switch includes a prepare switch button that is depressible into the housing.

11. The hand switch of claim 9 including a housing wherein the expose switch includes an expose switch button that is depressible into the housing.

12. The hand switch of claim 10 wherein the prepare switch button is spring loaded to urge the button outwardly of the housing.

13. The hand switch of claim 11 wherein expose switch button is spring loaded to urge the button outwardly of the housing.

14. The hand switch of claim 9 wherein the prepare switch is electrically connected to the x-ray machine to initiate the prepare sequence for the machine.

15. The hand switch of claim 14 wherein the tactile indicator is electrically connected to the x-ray machine so as to be activated upon completion of the prepare sequence.

16. The hand switch of claim 15 wherein the tactile indicator is a vibrating motor.
