Abstract

Claims (36)

1. A contamination identification system, comprising:

a patient support apparatus including a support frame disposed on a base;

a first light source directly coupled to the patient support apparatus, wherein the first light source emits visible light toward a support surface of the support frame;

a first controller operably coupled to the patient support apparatus, wherein the first controller activates the first light source to emit the visible light; and

a contamination detection device freely movable relative to the patient support apparatus, the contamination detection device including:

a body;

a second light source coupled to the body and that emits ultraviolet light;

a second controller disposed in the body and that activates the second light source to illuminate contamination on the patient support apparatus, wherein the second controller is communicatively coupled to the first controller for activating the second light source; and

a user-interface for receiving a command input relating to at least one of the first light source and the second light source, wherein the user-interface is coupled to the body and communicatively coupled to the second controller, and wherein the user-interface includes a touch screen coupled to a top surface of the body.

2. The contamination identification system of claim 1 , wherein the contamination detection device is a remote device free of a direct mechanical connection to the patient support apparatus.

3. The contamination identification system of claim 2 , wherein the contamination detection device communicates with the patient support apparatus via a wireless communication interface.

4. The contamination identification system of claim 1 , wherein the first light source is activated through the command input received by the user-interface.

5. The contamination identification system of claim 1 , wherein the touch screen displays a first display screen with first user options and a second display screen with second user options, wherein the second display screen is displayed after a selection of one of the first user options.

6. The contamination identification system of claim 1 , wherein the visible light has a wavelength in a range of 380 nm to 740 nm and the ultraviolet light has a wavelength in a range from 320 nm to 400 nm.

7. The contamination identification system of claim 1 , wherein the second light source emits the visible light simultaneously with the ultraviolet light as a direction confirmation.

8. The contamination identification system of claim 1 , wherein the first light source is directly coupled to the base of the patient support apparatus.

9. A contamination identification system for a healthcare setting, comprising:

a contamination detection device including:

a body;

a first light source coupled to the body; and

a controller operably coupled to the first light source, wherein the controller activates the first light source to emit ultraviolet light to illuminate contamination within said healthcare setting;

a second light source communicatively coupled with the controller, wherein the controller activates the second light source to emit visible light to illuminate said healthcare setting; and

healthcare equipment including a patient support apparatus disposed within said healthcare setting, wherein the second light source is directly coupled to a base of the patient support apparatus, and wherein the contamination detection device is freely movable relative to the healthcare equipment to illuminate the contamination on the healthcare equipment, and wherein the patient support apparatus includes a controller communicatively coupled to the controller of the contamination detection device for activating the second light source.

10. The contamination identification system of claim 9 , wherein the contamination detection device includes a user-interface coupled to the body for receiving a command input relating to at least one of the first light source and the second light source.

11. The contamination identification system of claim 10 , wherein the user-interface displays a first display screen with first user options and a second display screen with second user options, wherein the first user options and the second user options are different.

12. The contamination identification system of claim 11 , wherein the second user options relate to controlling the first light source.

13. A handheld contamination detection device for a healthcare setting, comprising:

a body having a top surface, a bottom surface, and an end surface extending between the top surface and the bottom surface;

a light source coupled to the end surface, wherein the light source emits ultraviolet light away from the body;

a user-interface coupled to the top surface of the body, wherein the user-interface includes a touch screen; and

a controller communicatively coupled with the light source, the user-interface, and at least one piece of healthcare equipment in said healthcare setting, wherein the controller receives a command input from the user-interface and activates the light source in response to the command input, and wherein the controller receives an additional command input from the user-interface and activates a light attached to the at least one piece of healthcare equipment in response to the additional command input.

14. The handheld contamination detection device of claim 13 , wherein the light source emits visible light simultaneously with the ultraviolet light as a direction confirmation.

15. The handheld contamination detection device of claim 13 , wherein the user-interface includes a first display screen having first user options and a second display screen having second user options, and wherein the second user options are displayed in response to a selection of one of the first user options.

16. The handheld contamination detection device of claim 15 , wherein the second user options include selectable features for activating or deactivating the light source.

17. The handheld contamination detection device of claim 13 , wherein a first end of the body has a greater thickness than a second end to provide a grasping location.

18. The handheld contamination detection device of claim 13 , wherein the ultraviolet light has a wavelength in a range from 320 nm to 400 nm.
