Films For Touchscreen Displays Of Medical Device Monitors
According to various embodiments, a medical device monitor includes a touchscreen and a film disposed on an external surface of the touchscreen. The film resists formation of visible fingerprints and resists growth of microorganisms. In various embodiments, one layer or more than one layer of the film may be disposed on the touchscreen.
1 . A medical device monitor comprising:
a touchscreen; and
a transparent film disposed on an external surface of the touchscreen, wherein the transparent film resists formation of visible fingerprints and resists growth of microorganisms.
2 . The medical device monitor of claim 1 , wherein the transparent film comprises a first material that resists formation of visible fingerprints and a second material that resists growth of microorganisms.
3 . The medical device monitor of claim 1 , wherein the transparent film adheres to the external surface of the touchscreen via static electricity or via an adhesive backing.
4 . The medical device monitor of claim 1 , wherein the transparent film is oleophobic, lipophobic, or a combination of both.
5 . The medical device monitor of claim 1 , wherein the transparent film comprises a nanostructure such that oils are absorbed and spread into a layer on an external surface of the transparent film.
6 . The medical device monitor of claim 1 , wherein the transparent film resists smudges from oil, blood, bodily fluids, dirt, or any combination thereof.
7 . The medical device monitor of claim 1 , wherein the transparent film comprises a composition that leaches into microorganisms.
8 . The medical device monitor of claim 1 , wherein the transparent film comprises a composition that ruptures cell walls of microorganisms.
9 . The medical device monitor of claim 1 , wherein the transparent film comprises a silver-based compound.
10 . The medical device monitor of claim 1 , wherein the transparent film resists scratching.
11 . The medical device monitor of claim 1 , wherein the transparent film reduces glare.
12 . The medical device monitor of claim 1 , wherein a thickness of the transparent film is between approximately 0.1 and 0.2 millimeters.
13 . A pulse oximetry system comprising:
a pulse oximetry monitor capable of receiving signals generated by a pulse oximetry sensor, the pulse oximetry monitor comprising:
a touchscreen; and
one or more layers of film disposed on an external surface of the touchscreen, wherein each layer of the film comprises a first material that resists formation of visible fingerprints and a second material that resists growth of microorganisms.
14 . The pulse oximetry system of claim 13 , wherein each layer of film comprises a separation region to enable one layer of film to be removed from the touchscreen at a time.
15 . The pulse oximetry system of claim 13 , wherein the film adheres to the external surface of the touchscreen and to other layers of film via an adhesive backing or via static electricity.
16 . The pulse oximetry system of claim 13 , wherein the first material of each layer of the film is disposed in a first sublayer and the second material is disposed in a second sublayer.
17 . The pulse oximetry system of claim 13 , wherein the first material comprises a nanoscale material that absorbs and/or spreads oils to reduce the visible display of fingerprints on the touchscreen.
18 . The pulse oximetry system of claim 13 , wherein the second material comprises a polymeric composition capable of killing microorganisms.
19 . The pulse oximetry system of claim 13 , wherein each layer of the film is oleophobic and/or lipophobic.
20 . A method of coating a touchscreen of a medical device monitor, the method comprising:
disposing a transparent film on an external surface of a touchscreen of a medical monitor, wherein the film resists formation of visible fingerprints and resists growth of microorganisms.
