Description

Technical Field

[0006] , ,

[0001] The present invention relates to an operation panel of a medical device.

Background Art

[0002] In the medical field, those inserted into the subject's body such as endoscopes are sterilized with a cleaning machine. There is also a concern that medical devices may be contaminated by droplets from subjects or medical staff, or viruses floating in the air, in peripheral devices such as processor devices and light source devices. Since contamination is likely to spread in operation panels and the like where medical staff often directly touch, it is necessary to perform sterilization and disinfection to always keep them clean. There is an additional need for sterilization and disinfection that can surely kill viruses such as the novel coronavirus (COVID-19).

[0003] However, in the method of cleaning with wiping or disinfectant solution, there is a case where it cannot be sufficiently cleaned in the uneven parts such as switches, or there is a risk of causing surface deterioration. In addition, in inspections such as endoscopes, the same device is often used for a large number of subjects within the day. If it is a method that takes time and effort, the burden on medical staff will increase.

[0004] In Patent Documents 1 and 2, a covering member such as a film is attached on the operation panel, and by peeling off the covering member, the cleanliness against contamination such as bacteria and viruses on the operation panel is maintained.

[0006] However, in Patent Documents 1 and 2, sterilization of the coating material is not performed, and there is a risk of contamination spreading during disposal after removal.

[0022] As shown in Figure 1, the endoscope system 10 connects to the processor unit 12 and the light source unit 15 when handling the endoscope 11, and these peripheral devices must also be used in parallel when inserting them into the patient for examination. The processor unit 12 is also connected to the display 13 and the user interface 14. The light source unit 15 and the processor unit 12 are enclosed units, with the light source unit 15 having an operation panel 20a in the center of its front, and the processor unit 12 having an operation panel 20b in the center of its front, which the user operates by touching them directly.

[0023] As shown in Figure 2, the endoscope system 10 includes an endoscope 11, a processor unit 12, a light source unit 15, a display 13, and a user interface (UI) 14, etc. The endoscope 11 is optically connected to the light source unit 15 and electrically connected to the processor unit 12. The processor unit 12 is electrically connected to both the display 13 and the user interface 14. Although not shown in Figure 1, the air and water supply unit 16 is physically connected to the endoscope 11 and may have an operation panel. Similarly to the air and water supply unit 16, endoscope peripheral equipment such as a balloon controller, navigation device, diagnostic support device, or treatment instrument power supply may also have an operation panel and be connected to the endoscope 11.

[0024] As shown in Figure 3, the operation panel 20a of the light source device 15 comprises a panel cover 21 (not shown) and a panel section 22. The panel cover 21 covers the button section 23. A character display section 24 is provided on the surface of the panel cover 21. The panel cover 21 covers the surface of the operation panel 20a other than the panel section 22. A power switch 25a for controlling the power supply and a human presence sensor 26a for detecting the presence or absence of a person are provided near the operation panel 20a. Alternatively, part or all of the button section 23 and the character display section 24 may be configured as the panel section 22. In that case, the panel section has the functions of the button section 23 and the character display section 24. Since the human presence sensor 26a is not a mechanism for display or operation, it may be installed in a location away from the operation panel 20a, such as on the side of the light source device 15. The configuration of the operation panel 20a, power switch 25a, and human presence sensor 26a of the light source device 15 can also be applied to the operation panel 20b of the processor device 12 and the air supply / water supply device 16.

[0025] The surface of the control panel 20a has a light-illuminated area that receives light from a light source located on the inner side. The light-illuminated area includes the entire panel section 22 equipped with a backlight, as well as each button on the button section 23 that indicates the on / off status of functions controlled by turning them on and off, and each character display on the character display section 24 that describes the function of each button and lights up when the function is on. The light source includes an illumination light source 31 that emits illumination light, as well as an ultraviolet light source 32 that emits ultraviolet light.

[0026] As shown in Figure 4, the processor unit 12, like the light source unit 15, has an operation panel 20b, a power switch 25b, and a human presence sensor 26b. The operation panel 20b is equipped with an examination switch 27 for controlling the start and end of endoscopic examinations, which is not present in the light source unit 15 or other peripheral devices for endoscopy.

[0027] Figure 5 is an enlarged view of the lower left portion of the operation panel 20a (see Figure 3) of the light source device 15. Preferably, the operation panel 20a is equipped with a character display section 24 in a position adjacent to the button section 23, such as directly above it, to display the name or graphic (pictogram) of each button. The button section 23 is equipped with buttons 23a and 23b, and similarly, a character display section 24 is provided above and next to each of them, character display 24a and character display 24b. The characters or graphics on the button section 23 and the character display section 24 are written transparently or semi-transparently so that they light up when illuminated by the panel cover 21 (not shown) on the surface. Furthermore, a cross-sectional view of the button section 23 in Figure 5 is shown in Figure 7, a cross-sectional view of the character display section 24 is shown in Figure 10, and cross-sectional views of the panel section 22 are shown in Figures 11, 12, and 15.

[0028] Each button on the button section 23 changes its illumination state depending on its function, such as being constantly lit, turning on or off when pressed, or changing color when pressed. At least the parts of the panel cover 21 that have graphics or letters are transparent or semi-transparent to indicate illumination.

[0029] As shown in Figure 6, the illumination light source 31 and the ultraviolet light source 32 are controlled by the control unit 30, which controls the intensity, duration, and pattern of illumination light and ultraviolet light irradiation according to instructions from the processor. The processor issues instructions in response to one or more combinations of operations on the button unit 23, the power switch 25a, the inspection switch 27, and detection by the human presence sensor 26a. The irradiation time can be set arbitrarily by the user in advance, and it is preferable to set it to a time that allows for sufficient sterilization, such as irradiation for 5 minutes after pressing a button. In addition, the irradiation periods of the illumination light source 31 and the ultraviolet light source 32 may or may not be linked.

[0030] Furthermore, it is preferable that the ultraviolet light source 32 also emits light in conjunction with the power switch 25a, similar to how the illumination light source 31 turns on when the power switch 25a is turned off, and how the illumination of the panel section 22 and button section 23 turns on or off.

[0031] The ultraviolet light source 32 can be either an excimer lamp or an ultraviolet LED (Light Emitting Diode). The excimer lamp preferably emits first ultraviolet light with a peak wavelength of 222 nm (±10 nm) and a wavelength range of 200 nm to 280 nm. The biological transmittance of first ultraviolet light is lower than that of 254 nm ultraviolet light (specific ultraviolet light), which has a higher light intensity. For example, the transmittance of the cornea of ​​the eye (the percentage of light absorbed by the cornea out of the light incident on the cornea) is 0.01% for first ultraviolet light, compared to 30% for specific ultraviolet light. Therefore, first ultraviolet light is safe for the skin and eyes of humans and animals.

[0032] UV LEDs preferably emit deep ultraviolet light (secondary ultraviolet light) with a wavelength range of 300 nm or less. Secondary ultraviolet light has the function of destroying the genetic information of viruses and bacteria, and therefore has a sterilizing effect on water and air. For example, secondary ultraviolet light has a high sterilizing effect against human coronavirus (HCoV-229E). In addition, UV LEDs preferably have functions such as waterproofing or heat dissipation. UV LEDs have a smaller impact on the environment compared to mercury lamps.

[0033] As shown in Figures 7 and 8, the button 23a comprises a panel cover 21, an illumination light source 31, an ultraviolet light source 32, a light guide material 33, a frame 34, a switch 35, and a substrate 36. The light guide material 33, located on the inner surface of the button portion 23, transmits the illumination light emitted from the illumination light source 31 and the ultraviolet light emitted from the ultraviolet light source 32, both located on the substrate 36, to the panel cover 21. The light guide material 33 is preferably cylindrical in shape, corresponding to the shape of the button 23a or button 23b, and is made of a transparent silicone rubber or similar material that transmits illumination light and ultraviolet light. The area of ​​the panel cover 21 occupied by the button 23a becomes the light irradiation area where illumination light or ultraviolet light transmitted through the light guide material 33 is applied.

[0034] When a user presses any button, the light guide material 33 contacts the switch 35 on the substrate 36 via the panel cover 21, causing at least one of the illumination light source 31 or the ultraviolet light source 32 to emit light. When the panel cover 21 is irradiated with ultraviolet light, the ultraviolet light penetrates to the outside of the panel cover, causing sterilization.

[0035] As shown in Figure 9, two illumination light sources 31 and two ultraviolet light sources 32 may be installed for each button, such as button 23a, to increase the emission of the irradiated light. Note that the shaded areas are applied to the ultraviolet light sources 32 to distinguish them from the illumination light sources 31 that are not shaded, and do not represent any difference in appearance.

[0036] As shown in Figure 10, in the character display unit 24, an illumination light source 31 and an ultraviolet light source 32 are provided on the substrate 36 for each character display. A frame 34 is provided between the panel cover 21 and the substrate 36, but its shape does not obstruct the irradiation of the panel cover 21 with illumination light and ultraviolet light. The panel cover 21 around the displayed character becomes the light irradiation area. For example, when illumination light is irradiated onto the character display 24a, the characters "Transmitted Illumination" light up, and similarly, when ultraviolet light is irradiated, sterilization is performed around the characters "Transmitted Illumination".

[0037] The panel section 22 (see Figure 5) is backlit when displaying an image, and the panel section 22 includes at least one of either a touch panel 37 or a liquid crystal panel 38. When both a touch panel 37 and a liquid crystal panel 38 are present, the touch panel 37 is on the surface side and the liquid crystal panel 38 is on the inner side. Because the touch panel 37 has a transparent structure, light that reaches the surface of the liquid crystal panel 38, which is in contact with the inner surface of the touch panel 37, is transmitted to the surface of the touch panel 37. The backlight is a surface light source that illuminates the entire image display surface of the panel section 22 from the inner side with a nearly uniform brightness by transmitting illumination light from the illumination light source 31 through a light guide plate 40 or a diffuser plate 42. Ultraviolet light similarly illuminates the panel section 22 nearly uniformly. Therefore, the light illumination area includes the entire illumination range of the backlight of the panel section 22. If the panel section 22 does not include a touch panel 37, the backlight of the entire panel section is illuminated without using a light guide plate 40 or a diffuser plate 42.

[0038] As shown in Figure 11, the light guide plate 40, which has an illumination light source 31 on its end face, and the ultraviolet light guide plate 41, which has an ultraviolet light source 32 on its end face, are molded into a rectangular shape and are positioned to overlap the inner surface of the panel section 22. In the light guide plate 40, the light source optically connected to the end face is positioned along it, and the illumination light that enters the interior from the end face is reflected inside, so that it illuminates from an illumination surface that is approximately the same size as the panel section 22. The illumination light lights up as a backlight in conjunction with the display of the liquid crystal panel 38 located on the inner surface of the panel section 22. The area where the backlight lights up is also a light irradiation area, and the ultraviolet light irradiated from the ultraviolet light guide plate 41 located on the substrate 36 side works in the same way as the light guide plate 40. In this case, the ultraviolet light irradiated from the ultraviolet light guide plate 41 passes through the light guide plate 40, and the touch panel 37 located on the surface side of the panel section 22 is sterilized.

[0039] As shown in Figure 12, the light guide plate 40 may also function as an ultraviolet light guide plate 41. The ultraviolet light source 32 (not shown in Figure 12) is arranged alternately with the illumination light source 31 on the end face side of the light guide plate 40, and the illumination light and ultraviolet light incident from the end face irradiate the panel section 22 from the irradiation surface of the light guide plate 40, respectively.

[0040] Figure 13 is a view of Figure 12 from the Y direction. Illumination light sources 31 and ultraviolet light sources 32 are alternately arranged on the end face side. Note that the illumination light sources 31 and ultraviolet light sources 32 may be placed not only on one end face side of the light guide plate 40, but also on the other end face side, allowing light to be incident from two directions.

[0041] As shown in Figure 14, the light guide plate 40 and the ultraviolet light guide plate 41, which are arranged in overlapping positions in Figure 11, may be arranged alternately to form a single plate. In this case, the end faces of each light guide plate 40 are irradiated with illumination light from the illumination light source 31, and the end faces of the ultraviolet light guide plate 41 are irradiated with ultraviolet light from the ultraviolet source 32.

[0042] As shown in Figure 15, the rectangular diffuser plate 42 formed on the inner surface of the panel section 22 diffuses the light incident from the incident surface and irradiates it from the irradiation surface. An illumination light source 31 and an ultraviolet light source 32 are provided on the substrate 36 directly below the diffuser plate 42, arranged in a planar manner, and are optically connected to the diffuser plate 42. The illumination light and ultraviolet light incident inside the diffuser plate 42 from the incident surface are diffused inside, so that they irradiate from an irradiation surface that is approximately the same size as the panel section 22. The illumination light lights up as a backlight in conjunction with the display of the liquid crystal panel 38 located on the inner surface of the panel section 22. In addition, the area where the backlight lights up is a light irradiation area, and ultraviolet light is also irradiated there, sterilizing the touch panel 37 located on the surface side of the panel section 22. As shown in Figure 16, it is preferable that the illumination light source 31 and ultraviolet light source 32 on the substrate 36 be arranged alternately in a planar manner.

[0043] The timing of ultraviolet irradiation by the ultraviolet source 32 can be determined by the following seven irradiation patterns. The first and second irradiation patterns are performed before the inspection, the third irradiation pattern is performed during the inspection, the fourth to sixth irradiation patterns are performed after the inspection, and the seventh irradiation pattern is performed as needed. In the first to sixth irradiation patterns, the ultraviolet source 32 irradiates the entire light irradiation area of ​​the medical device with ultraviolet light. Furthermore, it is preferable to combine these irradiation patterns, including the seventh irradiation pattern, depending on the usage environment of the medical device and the inspection conditions. The first to seventh irradiation patterns are performed by controlling the ultraviolet source 32 with the control unit 30. When the medical device (light source device 15 or processor device 12) has at least one of a power switch 25a, an inspection switch 27, and a human presence sensor 26a, the control unit 30 performs the first to seventh irradiation patterns by controlling the ultraviolet source 32 with one or more combinations of operations on the power switch 25a, the inspection switch 27, and the human presence sensor 26a.

[0044] Prior to the examination, it is preferable that the medical equipment be as sterilized as possible at the start of the examination. In the first irradiation pattern, when the power switch 25a is turned on, the ultraviolet source 32 irradiates with ultraviolet light for a certain period of time in conjunction with the illumination light source 31. In the second irradiation pattern, after the power switch 25a is turned on, the ultraviolet source 32 is linked to the examination reservation system and irradiates with ultraviolet light at a predetermined time before the examination time.

[0045] During the examination, the medical device is at increased risk of contamination from droplets and other substances from multiple people, including the patient, so it is preferable to maintain a sterilized state. In the third irradiation pattern, the ultraviolet source 32 irradiates with ultraviolet light in conjunction with the start of the examination by pressing the examination switch 27. During the examination, medical personnel, including the user, and the patient are in close proximity to the medical device, so irradiation is possible when using the first ultraviolet light, which is safe for the skin and eyes of humans and animals. While illumination light is constantly irradiated during the examination, ultraviolet irradiation may also be constantly irradiated, or it may be repeatedly turned on and off at regular intervals.

[0046] After the examination, droplets and viruses may adhere to the medical device, especially the control panel, during the series of examination processes. Since the same medical device may be used to examine multiple patients in one day, it is desirable to thoroughly sterilize it to prevent contamination from remaining for the next examination. The fourth irradiation pattern is that when the examination is completed by pressing the examination switch 27, the ultraviolet source 32 activates and irradiates with ultraviolet light for a certain period of time. The fifth irradiation pattern is that when the power switch 25a is turned off, the ultraviolet source 32 activates and irradiates with ultraviolet light for a certain period of time. The sixth irradiation pattern is that when the human presence sensor 26a determines that no one is present, the ultraviolet source 32 activates and irradiates with ultraviolet light for a certain period of time.

[0047] Regardless of the timing of the inspection, the medical device's control panel 20a is frequently touched by the user's fingers, making it highly susceptible to the attachment of viruses and other contaminants. Therefore, it is preferable to perform sterilization in accordance with the frequency of finger contact. In the seventh irradiation pattern, when buttons such as buttons 23a and 23b of the button section 23 are pressed, the ultraviolet source 32 is activated in conjunction to irradiate at least the pressed button and the corresponding character display panel cover 21 with ultraviolet light for a certain period of time. In the seventh irradiation pattern, at least the user is near the medical device, so irradiation is possible when irradiating with the first ultraviolet light, similar to the third irradiation pattern.

[0048] In the first to fourth and seventh irradiation patterns, when the power switch 25a is turned on while the medical device is in use, the illumination light source 31 and the ultraviolet light source 32 are operated simultaneously to irradiate with illumination light and ultraviolet light. However, in the fifth and sixth irradiation patterns, when only ultraviolet irradiation is performed after the medical device has been used, only the ultraviolet light source 32 is operated, and so on, allowing for selective operation. When selectively controlling the light source, it is preferable to give instructions via the control panel 20a, such as setting the start and end of irradiation from the control panel 20a.

[0049] As shown in Figure 17, even if the medical device is not included in the endoscope system 10, sterilization functions using the illumination light source 31 and ultraviolet light source 32 may be provided to related equipment for endoscopic examinations that has a part similar to or the same as the control panel 20a. Figure 17 shows an endoscope cleaning device 50, which cleans an endoscope 11 that has been used for examination. The endoscope cleaning device 50 has a control panel 51 that the user touches with their finger to start and stop cleaning, set the cleaning time, etc. Sterilization of the light-irradiated area with ultraviolet light is performed each time the user operates the control panel 51.

[0050] In the above embodiment, the hardware structure of the processing unit that performs various processes, such as the control unit 30, is a variety of processor as shown below. These various processors include a CPU (Central Processing Unit), which is a general-purpose processor that executes software (programs) and functions as a processing unit; a Programmable Logic Device (PLD), which is a processor whose circuit configuration can be changed after manufacturing, such as an FPGA (Field Programmable Gate Array); and a dedicated electrical circuit, which is a processor with a circuit configuration specifically designed to perform various processes.

[0051] A single processing unit may be composed of one of these various processors, or it may be composed of a combination of two or more processors of the same or different types (for example, multiple FPGAs, or a combination of a CPU and an FPGA). Alternatively, multiple processing units may be composed of a single processor. Examples of composing multiple processing units with a single processor include, firstly, a configuration where one or more CPUs and software are combined to form a single processor, and this processor functions as multiple processing units, as is typical of computers such as client and server systems. Secondly, a configuration using a processor that realizes the functions of the entire system, including multiple processing units, on a single IC (Integrated Circuit) chip, as is typical of System-on-a-Chip (SoC) systems. Thus, various processing units are configured, in terms of hardware structure, using one or more of the above-mentioned various processors.

[0052] Furthermore, the hardware structure of these various processors is, more specifically, an electrical circuit formed by combining circuit elements such as semiconductor devices. The hardware structure of the memory unit is a storage device such as an HDD (hard disk drive) or SSD (solid state drive). [Explanation of symbols]
