Description

[Technical Field]

[0001] The embodiments disclosed in this specification and drawings relate to a disinfection device.

[0002] Conventionally, keyboards and mice equipped with trackballs and dedicated operation panels have been known as input interfaces for inputting operations to computers. For example, operation panels equipped with trackballs are sometimes used in medical devices such as ultrasound diagnostic equipment.

[0003] In such circumstances, there are cases where multiple operators use the same input interface. Furthermore, there are cases where the same medical device, such as an ultrasound probe of an ultrasound diagnostic device, is used for multiple subjects. In these cases, in order to prevent the spread of infection due to the transfer of microorganisms, bacteria, or viruses through the contact area, a disinfection process is performed in which the contact area is disinfected with a cloth soaked in alcohol. Here, disinfection refers to, for example, a process of reducing the number of microorganisms, bacteria, or viruses, or a process of detoxifying microorganisms, bacteria, or viruses. In other words, disinfection includes the removal and / or killing of at least a portion of microorganisms or bacteria. Furthermore, disinfection includes the removal and / or inactivation of at least a portion of viruses.

[0004] However, it was time-consuming to prepare alcohol and cloths for each disinfection procedure. In addition, disinfecting trackballs that are not entirely exposed and ultrasound probes with complex shapes took time, and there were cases where the next examination could not be started due to disinfection.

[0009] The disinfection apparatus and ultrasound diagnostic apparatus according to each embodiment will be described below with reference to the drawings. In the following description, components having the same or substantially the same functions as those described above with reference to the previous drawings will be designated by the same reference numerals and will be described only if necessary. Even when the same parts are shown, the dimensions and proportions may be different depending on the drawing. Furthermore, for example, in order to ensure the visibility of the drawings, only the main components may be designated by reference numerals in the description of each drawing, and components having the same or substantially the same functions may not be designated by reference numerals.

[0010] In the embodiments described below, disinfection refers to reducing the number of microorganisms, bacteria, or viruses, or detoxifying microorganisms, bacteria, or viruses. In other words, disinfection includes removing and / or killing at least a portion of microorganisms or bacteria. Disinfection also includes removing and / or inactivating at least a portion of viruses.

[0011] In the embodiments described below, disinfection of an object is mainly illustrated, but the invention is not limited to this. The technology according to each embodiment can also be applied to cleaning, such as removing dirt adhering to an object.

[0012] (First embodiment) 1 is a diagram showing an example of the configuration of a disinfection system 9 according to an embodiment. As shown in FIG. 1, the disinfection system 9 includes an ultrasonic diagnostic apparatus 1 and a disinfection apparatus 7.

[0013] 1, the ultrasound diagnostic device 1 has a device main body 10, a display 30, and an input interface 50. An ultrasound probe 20 is detachably connected to the device main body 10. The ultrasound probe 20 is connected to the device main body 10 via a cable 21.

[0014] The device main body 10 performs overall control of the ultrasound diagnostic device 1. For example, the device main body 10 executes various controls related to the generation of ultrasound image data based on the reflected waves of ultrasound received by the ultrasound probe 20. The display 30 displays ultrasound image data generated by the device main body 10, and displays a GUI (Graphical User Interface) that allows the operator of the ultrasound diagnostic device to input operations such as various settings using the input interface 50. In addition, the input interface 50 accepts operation inputs from the operator of the ultrasound diagnostic device 1 and transmits operation signals to the device main body 10 in accordance with the accepted operation inputs.

[0015] The ultrasonic probe 20 has a plurality of transducers 22 (see FIG. 6), and these transducers 22 generate ultrasonic waves based on drive signals supplied from a transmission / reception circuit 110 included in the device main body 10. The ultrasonic probe 20 also receives reflected waves from the subject P and converts them into electrical signals.

[0016] Note that there is no particular limitation on the form of the ultrasonic probe 20, and any form of ultrasonic probe may be used. For example, the ultrasonic probe 20 may be a 1D array probe that scans the subject P in two dimensions. Alternatively, the ultrasonic probe 20 may be a mechanical 4D probe or a 2D array probe that scans the subject P in three dimensions.

[0017] The display 30 displays various types of information and images. Specifically, the display 30 converts information and image data sent from the processing circuit 170 (see FIG. 6) into electrical signals for display and outputs the signals. For example, the display 30 may be implemented by a liquid crystal monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like. Note that the output device provided in the ultrasound diagnostic apparatus 1 is not limited to the display 30 and may include, for example, a speaker. For example, the speaker outputs a predetermined sound, such as a beep, to notify the operator of the processing status of the apparatus main body 10.

[0018] The input interface 50 accepts various instructions and information input operations from an operator. Specifically, the input interface 102 converts the input operations accepted by the operator into electrical signals and outputs them to the processing circuit 170 (see FIG. 6) of the device main body 10. As shown in FIG. 1, the input interface 50 includes a trackball 51, switches 53, buttons 55, a touch command screen 57, and the like arranged on an operation panel. FIG. 1 illustrates a first operation panel provided with the trackball 51, switches 53, and buttons 55, and a second operation panel provided with the touch command screen 57. The second operation panel may be integrated with the display 30. The input interface 50 is not limited to those having physical operation components as described above. For example, an example of the input interface 50 also includes an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the device and outputs the electrical signal to a control circuit.

[0019] In this embodiment, the trackball 51 of the input interface 50 is exemplified as the target of disinfection by the disinfection device 7. That is, in this embodiment, the trackball 51 is an example of the input interface 50 that accepts operation input by the operator of the ultrasound diagnostic apparatus 1. Furthermore, in the following description, the term "operation panel" refers to the first operation panel on which at least the trackball 51 is mounted.

[0020] The trackball 51 is configured to rotate in response to an operation by an operator. The trackball 51 has, for example, a spherical rotating member and a detection device that detects the amount and direction of rotation of the rotating member. In this embodiment, the area of ​​the surface of the rotating member of the trackball 51 that is exposed to the operator is referred to as the exposed surface (exposed portion). Also, in this embodiment, the other area of ​​the surface of the rotating member of the trackball 51 that is exposed is referred to as the back surface. The exposed surface and back surface of the rotating member change position on the surface of the rotating member as the rotating member is rotated.

[0021] Sterilization device 7 is configured to perform a sterilization operation on trackball 51. Sterilization device 7 is attached to an operation panel on which trackball 51 is mounted so as to be pressed against trackball 51 during the sterilization operation.

[0022] As shown in Fig. 1, the sterilization device 7 has a device main body 701 and an attachment member 703. The attachment member 703 is provided at a contact portion with the operation panel, for example, below the device main body 701 (in the Z-direction in Fig. 1). The attachment member 703 is formed so as to be attachable to the trackball 51, which is an example of an object to be sterilized, so as to cover the trackball 51.

[0023] As an example, the mounting member 703 is configured to reduce a gap between the disinfection device 7 and the operation panel when the disinfection device 7 is attached to the operation panel.

[0024] As an example, the mounting member 703 is formed in a shape that conforms to the shape of the operation panel on which the trackball 51 is provided.

[0025] For example, the mounting member 703 has a shape that conforms to the unevenness around the trackball 51 on the operation panel, that is, the surface shapes of the switches 53 and buttons 55 provided around the trackball 51 .

[0026] 1 illustrates mounting member 703 having a rectangular shape, the shape of mounting member 703 may be determined appropriately according to the irregularities of the surface of the operation panel on which trackball 51 to be disinfected is provided, and may also be circular. For example, mounting member 703 has a shape that fits inside a plurality of buttons 55 provided in a ring shape around trackball 51 on the operation panel.

[0027] As an example, the mounting member 703 is configured to be deformable so as to fit the shape of the operation panel on which the trackball 51 is provided.

[0028] For example, the mounting member 703 is made of a material having elasticity and / or flexibility, such as rubber or silicone.

[0029] As an example, the mounting member 703 and the device main body 701 are each formed from a material that has a high absorptivity or reflectivity for the ultraviolet light from the sterilization mechanism 75a.

[0030] As an example, the surfaces of the mounting member 703 and the device main body 701 are provided with a layer made of a material that has a high absorptivity or reflectivity for the ultraviolet light from the sterilization mechanism 75a.

[0031] The mounting member 703 and the device main body 701 may be formed integrally, or may be formed separately and then assembled together.

[0032] Fig. 2 is a diagram showing an example of the configuration of the sterilization device 7 according to the embodiment. As shown in Fig. 2, the device body 701 of the sterilization device 7 has a processing circuit 71, rotation mechanisms 73a and 73b, sterilization mechanisms 75a, 75b, and 75c, a detection circuit 77, and an indicator 79. The processing circuit 71, rotation mechanisms 73a and 73b, sterilization mechanisms 75a, 75b, and 75c, the detection circuit 77, and the indicator 79 are each provided in the device body 701 of the sterilization device 7.

[0033] In the following description, when there is no need to distinguish between the rotation mechanisms 73a and 73b, they will be collectively referred to as the rotation mechanism 73. Similarly, when there is no need to distinguish between the disinfection mechanisms 75a, 75b, and 75c, they will be collectively referred to as the disinfection mechanism 75.

[0034] Inner wall 705 of sterilizer 7 is a part of the surface of device body 701. Inner wall 705 is provided at a position facing the exposed portion of trackball 51 when sterilizer 7 is attached to trackball 51. Inner wall 705 is formed in a shape that follows the shape of the object to be sterilized, i.e., the exposed portion of trackball 51. In other words, inner wall 705 has a shape that fits the exposed portion of trackball 51.

[0035] As an example, the inner wall 705 has a hemispherical shape that conforms to the shape of the hemispherical exposed surface of the trackball 51 .

[0036] For example, the inner wall 705 is provided with a reflective layer made of a material that has a high reflectivity to the ultraviolet light emitted from the sterilization mechanism 75a.

[0037] Rotation mechanisms 73 are configured to be able to rotate trackball 51 in at least one rotational direction when attached to trackball 51. Rotation mechanisms 73 each have an actuator such as a motor, and a transmission member that transmits power from the actuator to trackball 51. The transmission member is provided at a position that contacts the exposed surface of trackball 51 when sterilization device 7 is attached to trackball 51. For example, the transmission member is provided so that a portion of it protrudes from inner wall 705.

[0038] As an example, the disinfection apparatus 7 has a plurality of rotation mechanisms 73a and 73b as shown in Fig. 2. The rotation mechanisms 73a and 73b are configured to rotate the trackball 51 around different rotation axes. For example, the rotation mechanism 73a is configured to rotate the trackball 51 around the Y-axis as the rotation axis. Furthermore, for example, the rotation mechanism 73b is configured to rotate the trackball 51 around the Z-axis as the rotation axis.

[0039] As an example, rotation mechanism 73 has multiple transmission members that transmit power from a common actuator as power in different directions to trackball 51. For example, one transmission member is configured to rotate trackball 51 around the Y-axis as a rotation axis. Furthermore, for example, the other transmission member is configured to rotate trackball 51 around the Z-axis as a rotation axis.

[0040] The direction of rotation of trackball 51 by rotation mechanism 73 is not limited to the above example and can be designed arbitrarily. The axis of rotation of trackball 51 by rotation mechanism 73 may be one axis or three or more axes.

[0041] The disinfection mechanism 75 is configured to be able to disinfect the trackball 51 while attached to the trackball 51. The disinfection mechanism 75 is configured to be able to disinfect the exposed portion of the outer surface of the trackball 51 that is exposed to the outside.

[0042] 2, the disinfection device 7 has a disinfection mechanism 75a configured to irradiate ultraviolet light UVL onto the outer surface of the exposed portion, i.e., the exposed surface, of the trackball 51. The disinfection mechanism 75a is an ultraviolet light source such as an LED (Light Emitting Diode) that generates ultraviolet light having a wavelength in a predetermined ultraviolet region.

[0043] The sterilization mechanism 75a may be any other ultraviolet source such as a mercury lamp as long as it can generate ultraviolet light. The ultraviolet light from the sterilization mechanism 75a is, for example, deep ultraviolet light (UV-C) having a wavelength of about 200 to 280 nm.

[0044] 2, the disinfection device 7 has a disinfection mechanism 75b configured to generate ozone. The ozone generated by the disinfection mechanism 75b is diffused into the space between the exposed surface of the trackball 51 and the inner wall 705 through an opening provided in the inner wall 705. In other words, the disinfection mechanism 75b is configured to generate ozone near the outer surface of the trackball 51.

[0045] As an example, as shown in FIG. 2, the disinfection device 7 has a disinfection mechanism 75c configured to be able to wipe the exposed surface of the trackball 51. The disinfection mechanism 75c has a wiping member, a storage unit, and a supply unit. The wiping member is provided in a position that contacts the exposed surface of the trackball 51 when the disinfection device 7 is attached to the trackball 51. For example, the wiping member is provided so that a portion of it protrudes from the inner wall 705. The storage unit stores a disinfectant such as alcohol. The supply unit is configured to soak the wiping member in the disinfectant stored in the storage unit. In other words, the disinfection mechanism 75c is configured to be able to wipe the outer surface of the trackball 51 with a wiping member soaked in disinfectant.

[0046] 2 illustrates an example in which one disinfection mechanism 75a, one disinfection mechanism 75b, and one disinfection mechanism 75c are provided, but this is not limiting. For example, one of the disinfection mechanisms 75a, one of the disinfection mechanisms 75b, and one disinfection mechanism 75c may not be provided. Furthermore, for example, at least one of the disinfection mechanisms 75a, one of the disinfection mechanisms 75b, and one disinfection mechanism 75c may be provided in multiple locations.

[0047] The detection circuit 77 is configured to be able to detect attachment of the sterilizer 7 to the trackball 51. The detection circuit 77 is a sensor for detecting that the sterilizer 7 is attached to the operation panel. For example, the detection circuit 77 is provided at a position where it comes into contact with the operation panel when the sterilizer 7 is attached to the trackball 51. For example, the detection circuit 77 is a switch configured to be turned on when the sterilizer 7 is pressed against the trackball 51.

[0048] Here, the sterilization device 7 pressing against the trackball 51 means that the sterilization device 7 is attached to the operation panel so that the exposed surface of the trackball 51 can be disinfected by the sterilization mechanism 75. Note that pressing does not necessarily mean that the operator applies force when making contact.

[0049] In this embodiment, attaching the disinfection device 7 to the operation panel so that the exposed surface of the trackball 51 can be disinfected may also be described as simply attaching the disinfection device 7 to the operation panel or trackball 51, or pressing the disinfection device 7 against the operation panel or trackball 51.

[0050] As an example, when the disinfection device 7 is attached to the operation panel, it means that the disinfection device 7 is attached to the operation panel so that the inner wall 507, which has a shape that follows the shape of the exposed surface of the trackball 51, follows the exposed surface of the trackball 51.

[0051] The indicator 79 is configured to be able to present to the operator the status of disinfection of the trackball 51 by the disinfection mechanism 75. The disinfection status is, for example, at least one of the following: a state in which the power is off and the disinfection operation is not being performed; a state in which the power is on but the disinfection operation has not started; a state in which the disinfection operation has started and is in progress; and a state in which the disinfection operation has ended and disinfection has been completed. The indicator 79 is, for example, an LED. The indicator 79 emits light under the control of the processing circuit 71.

[0052] The indicator 79 may be configured to have a number of LEDs, or the number of lights that can be emitted may be changeable. The indicator 79 may be configured to emit light in a number of colors. The indicator 79 may be configured to display a text message or an icon. The indicator 79 may be configured to output a notification sound or a voice message.

[0053] 2 illustrates an example in which the indicator 79 is provided on the top surface of the sterilization device 7 (the surface on the Z+ side in FIG. 2), but the present invention is not limited to this. The indicator 79 may be provided at any position on the sterilization device 7 as long as the indicator 79 is visible to the user when the sterilization device 7 is attached to the trackball 51.

[0054] The processing circuitry 71 controls the overall operation of the sterilization apparatus 7. For example, the processing circuitry 71 has a processor and a memory as hardware resources.

[0055] Fig. 3 is a block diagram showing an example of the functional configuration of the sterilization device 7. As shown in Fig. 3, the processing circuit 71 is configured to realize a detection function 711, a disinfection control function 712, and a notification function 713. Here, the processing circuit 71 that realizes the detection function 711 is an example of a detection unit. Moreover, the processing circuit 71 that realizes the disinfection control function 712 is an example of a control unit. Moreover, the processing circuit 71 that realizes the notification function 713 is an example of a notification unit.

[0056] The detection function 711, disinfection control function 712, and notification function 713 do not necessarily have to be realized by a single processing circuit. A processing circuit may be configured by combining multiple independent processors, and the detection function 711, disinfection control function 712, and notification function 713 may be realized by each processor executing a program.

[0057] The term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), or an Application Specific Integrated Circuit (ASIC), a programmable logic device (e.g., a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA)).

[0058] The various processing functions executed by the processing circuit 71 are stored in the memory of the processing circuit 71 in the form of programs executable by a computer. The processing circuit 71 realizes the functions corresponding to each program by reading the programs from the memory and executing them using a processor. In other words, each circuit that has read each program has the function corresponding to the read program.

[0059] The memory of the processing circuit 71 includes storage circuits such as a ROM (Read Only Memory) and a RAM (Random Access Memory). Note that the memory of the processing circuit 71 may also be other storage circuits such as a semiconductor memory element such as a flash memory, a hard disk, or an optical disk, as appropriate.

[0060] In the detection function 711, the processing circuit 71 detects the attachment state of the sterilization device 7 to the trackball 51 based on the output of the detection circuit 77. Specifically, when the detection circuit 77 is a switch that turns on in the attachment state, the processing circuit 71 detects that the sterilization device 7 is attached to the trackball 51 in response to detecting a signal from the detection circuit 77.

[0061] In the disinfection control function 712, when the processing circuit 71 detects that the disinfection device 7 has been attached to the trackball 51, the processing circuit 71 initiates the disinfection operation of the trackball 51 by the disinfection mechanism 75. At this time, the processing circuit 71 disinfects the trackball 51 by the disinfection mechanism 75 while rotating the trackball 51 in at least one rotational direction by the rotation mechanism 73 to change the exposed portion. The processing circuit 71 terminates the disinfection of the trackball 51 by the disinfection mechanism 75 when the trackball 51 has been rotated a predetermined amount or more. Here, the threshold rotation amount is an amount of rotation equal to or greater than an amount of rotation estimated to result in at least one rotation in each of at least one rotational direction. For example, if the rotation speed of the rotation mechanism 73 is controlled by a control signal from the processing circuit 71, the processing circuit 71 can acquire the amount of rotation of the trackball 51 in each rotational direction by each of the rotation mechanisms 73a and 73b.

[0062] In the notification function 713, the processing circuit 71 notifies the operator by the indicator 79 of at least one of the start and end of disinfection of the trackball 51 by the disinfection mechanism 75. The processing circuit 71 monitors the attachment state of the trackball 51 based on the output of the detection circuit 77, and may notify the operator to correct the attachment state when the attachment state becomes inappropriate for disinfection.

[0063] Here, an example of the operation of the disinfection device 7 will be described with reference to the drawings. Figure 4 is a diagram showing an example of the flow of processing executed in the disinfection device 7.

[0064] In the detection function 711, the processing circuit 71 determines whether or not the sterilization device 7 is pressed against the trackball 51 based on the output of the detection circuit 77 (S101). When it is not determined that the sterilization device 7 is pressed against the trackball 51 (S101: No), the flow of FIG. 4 repeats the process of S101 at predetermined time intervals, for example, until it is determined that the sterilization device 7 is pressed against the trackball 51.

[0065] When it is determined that the sterilization device 7 is pressed against the trackball 51 (S101: Yes), the processing circuit 71 in the notification function 713 notifies the operator by the indicator 79 that sterilization has started.

[0066] As an example, in the notification function 713, the processing circuit 71 notifies the operator of the start of disinfection by starting the illumination of the indicator 79. As an example, if the indicator 79 has multiple LEDs, the processing circuit 71 notifies the operator of the start of disinfection by changing the number of illuminations of the indicator 79. As an example, if the indicator 79 is configured to emit light in multiple colors, the processing circuit 71 notifies the operator of the start of disinfection by changing the color of the light emitted by the indicator 79. For example, the processing circuit 71 changes the color of the light emitted by the indicator 79 from orange to red in response to power-on of the disinfection device 7.

[0067] In the notification function 713, the processing circuit 71 may notify the operator of the start of disinfection by displaying a text message or an icon, or by outputting a notification sound or a voice message, depending on the configuration of the indicator 79.

[0068] In the disinfection control function 712, the processing circuit 71 causes the disinfection mechanism 75 to disinfect the trackball 51 while rotating the trackball 51 with the rotation mechanism 73 (S103).

[0069] In addition, in the disinfection control function 712, the processing circuit 71 determines whether or not the trackball 51 has been rotated by the rotation mechanism 73 by a predetermined rotation amount or more (S104). Specifically, the processing circuit 71 determines whether or not the trackball 51 has been rotated by the rotation mechanisms 73a and 73b by a predetermined rotation amount or more in each rotation direction.

[0070] When it is not determined that the trackball 51 has been rotated by the predetermined amount or more (S104: No), the flow of FIG. 4 repeats the processes of S103 and S104 until the trackball 51 has been rotated by the predetermined amount or more.

[0071] When it is determined that the trackball 51 has been rotated by a predetermined amount or more (S104: No), the processing circuit 71 in the disinfection control function 712 stops the operation of the rotation mechanism 73 and the disinfection mechanism 75. In addition, in the notification function 713, the processing circuit 71 notifies the operator that disinfection has been completed by the indicator 79 (S105). After that, the flow in FIG. 4 ends.

[0072] As described above, the disinfection device 7 according to the embodiment includes the attachment member 703, the disinfection mechanism 75, the detection circuit 77, and the processing circuit 71. The processing circuit 71 is configured to start disinfecting the trackball 51 by the disinfection mechanism 75 when it detects attachment to the trackball 51 based on the output of the detection circuit 77.

[0073] According to this configuration, by placing the disinfectant device 7 on the top surface of the trackball 51 of the operation panel, i.e., by pressing it against the surface, the disinfection process, such as ultraviolet irradiation, can be started. This enables disinfection in a short time, for example, between examinations, and reduces the need to stop the examination for disinfection. Furthermore, by performing automatic disinfection using the disinfectant device 7, it is possible to eliminate the need to prepare alcohol or cloth for disinfection. Therefore, the disinfectant device 7 according to this embodiment can simplify the disinfection process.

[0074] The disinfection device 7 according to the embodiment also includes a rotation mechanism 73 configured to rotate the trackball 51 in at least one rotational direction while attached to the trackball 51. Here, the disinfection mechanism 75 is configured to disinfect the exposed portion of the outer surface of the trackball 51. The processing circuit 71 rotates the trackball 51 in at least one rotational direction using the rotation mechanism 73, thereby changing the exposed portion of the trackball 51, and disinfects the trackball 51 using the disinfection mechanism 75. With this configuration, the entire outer surface of the trackball 51 can be disinfected by automatically rotating the trackball 51 to change the exposed surface, i.e., by exposing the unexposed portion of the trackball 51. In other words, the disinfection device 7 according to the embodiment can disinfect the entire outer surface of the trackball 51 simply by pressing it against the trackball 51.

[0075] Furthermore, in the disinfection device 7 according to the embodiment, the inner wall 705 is provided in a position facing the exposed portion of the trackball 51 when the disinfection device 7 is attached to the trackball 51. The inner wall 705 is formed in a shape that conforms to the exposed portion of the trackball 51. This configuration reduces the distance between the trackball 51 and the disinfection mechanism 75 provided on the inner wall 705, allowing efficient irradiation of ultraviolet light from an ultraviolet light source such as an LED onto the trackball 51, for example. Furthermore, the gap between the trackball 51 and the inner wall 705 can be reduced, allowing efficient distribution of ozone over the outer surface of the trackball 51, for example. In other words, the disinfection device 7 according to the embodiment allows efficient disinfection of the trackball 51 simply by pressing it against the trackball 51.

[0076] Furthermore, in the disinfection device 7 according to the embodiment, the trackball 51 is an example of an input interface 50 that accepts operation inputs from the operator of the ultrasound diagnostic device 1. With this configuration, the trackball 51, which is on the operation panel of the ultrasound diagnostic device 1 that is touched by multiple operators such as doctors and technicians and which requires time-consuming wiping with a cloth soaked in a disinfectant such as alcohol, can be easily disinfected.

[0077] Furthermore, in the disinfection device 7 according to the embodiment, when the trackball 51 has been rotated a predetermined amount or more, the processing circuit 71 terminates the disinfection of the trackball 51 by the disinfection mechanism 75. With this configuration, the entire trackball can be disinfected efficiently.

[0078] Furthermore, the disinfection device 7 according to the embodiment includes an indicator 79 configured to be able to notify the operator of the status of disinfection of the trackball 51 by the disinfection mechanism 75. Here, the processing circuit 71 notifies the operator of at least one of the start and end of disinfection of the trackball 51 by the disinfection mechanism 75. With this configuration, the operator can easily grasp the completion of disinfection by the disinfection device 7, which starts simply by pressing it against the trackball 51. Furthermore, the processing circuit 71 may notify the operator that the attachment to the trackball 51 has become inappropriate for disinfection during disinfection. In this case, the operator can easily grasp whether the attachment state is appropriate. In other words, it is possible to reduce the occurrence of insufficient disinfection or the need to repeat disinfection.

[0079] Furthermore, in the disinfection device 7 according to the embodiment, the disinfection mechanism 75 includes at least one of disinfection mechanisms 75a, 75b, and 75c. Disinfection mechanism 75a is configured to irradiate the outer surface of trackball 51 with ultraviolet light. Disinfection mechanism 75b is configured to generate ozone near the outer surface of trackball 51. Disinfection mechanism 75c is configured to wipe the outer surface of trackball 51 with a wiping member soaked in a disinfectant. This configuration enables the trackball 51 to be disinfected appropriately according to the desired level of disinfection. Furthermore, when multiple types of disinfection mechanisms are included, the disinfection effect increases and the effect of eliminating the need for preparation for disinfection becomes more pronounced.

[0080] In disinfection control function 712, processing circuit 71 may determine to end disinfection of trackball 51 by disinfection mechanism 75 when a predetermined time has elapsed since the start of disinfection. Here, the threshold time is equal to or greater than the time estimated to be required to disinfect the entire trackball 51, based on, for example, the rotation speed of rotation mechanism 73 and the number of rotation axes. Even with this configuration, the entire trackball can be disinfected efficiently.

[0081] The sterilization device 7 may be configured to be able to optically detect the amount and / or direction of rotation of the trackball 51. In this case, the processing circuit 71 in the detection function 711 may acquire the amount of rotation of the trackball 51 for each direction of rotation based on the output of an optical sensor that optically detects the amount and / or direction of rotation of the trackball 51.

[0082] It should be noted that, for example, a rotary encoder may be connected to each transmission member of the rotation mechanism 73. In this case, the processing circuit 71 in the detection function 711 may obtain the amount of rotation of the trackball 51 in each rotation direction based on the output of the encoder.

[0083] In this embodiment, the trackball 51 is exemplified as the input interface 50 of the ultrasound diagnostic device 1, but this is not limiting. The object to be disinfected by the disinfection device 7 according to the embodiment may be a trackball mounted on another medical device, or may be a trackball mounted on another device other than the medical device. In either case, the same effects as those of the above-described embodiment can be obtained.

[0084] Other medical devices may include various medical imaging diagnostic devices such as an X-ray computed tomography (CT) device, a magnetic resonance imaging (MRI) device, an ultrasound diagnostic device, a SPECT-CT device that combines a SPECT (Single Photon Emission Computed Tomography) device and an X-ray CT device, and a PET-CT device that combines a PET (Positron Emission Computed Tomography) device and an X-ray CT device, as well as various other devices such as treatment devices, treatment planning devices, and medical workstations.

[0085] Other medical devices may include a computer having a keyboard or mouse with a trackball or a dedicated operation panel as an input interface for user input. For example, the computer may be an amusement machine that uses a trackball as an input interface. In other words, the disinfection device 7 according to the embodiment disinfects a keyboard or mouse with a trackball or a dedicated operation panel, regardless of whether these are provided as input interfaces for any device.

[0086] The disinfection device 7 can disinfect not only the trackball 51 but also elements whose exposed surface is part of the surface to be disinfected, such as a dial or a belt. In this case, the shape of the mounting member 703 of the disinfection device 7, the shape of the inner wall 705, the configuration and arrangement of the rotation mechanism 73, the configuration and arrangement of the disinfection mechanism 75, etc. may be appropriately designed according to the shape of the object to be disinfected.

[0087] (Second embodiment) In the first embodiment, the trackball 51 is exemplified as an object to be disinfected by the disinfection device 7, but this is not limiting. The disinfection device 7 may be configured to disinfect the ultrasound probe 20 of the ultrasound diagnostic device 1.

[0088] FIG. 5 is a diagram showing an example of the configuration of the adapter 8 attached to the disinfection device 7 of FIG.

[0089] The adapter 8 is configured so that the mounting member 703 of the sterilization device 7 can be attached thereto. The adapter 8 is also formed so that the ultrasonic probe 20 mounted on the ultrasonic diagnostic device 1 can be inserted therein.

[0090] As an example, the main body 801 of the adapter 8 can be divided into two or more parts along the direction of attachment to the sterilization device 7 or along the direction of insertion of the ultrasonic probe 20. In this case, the adapter 8 is configured so that it can be assembled by sandwiching the ultrasonic probe 20 between the divided main body 801.

[0091] As an example, the adapter 8 is attached to the ultrasonic probe 20 from the side of the cable 21 opposite to the ultrasonic probe 20. In other words, the ultrasonic probe 20 is inserted from the cable 21 to the side of the main body 801 that is attached to the mounting member 703. In this case, the main body 801 of the adapter 8 does not need to be configured to be separable.

[0092] The inner wall 802 of the adapter 8 is provided at a position facing the outer surface of the ultrasonic probe 20 when the ultrasonic probe 20 is inserted. The inner wall 802 is formed into a shape that fits the outer surface of the ultrasonic probe 20. In other words, the inner wall 802 has a shape that fits the outer surface of the ultrasonic probe 20.

[0093] The disinfection mechanism 75 is configured to disinfect the ultrasonic probe 20 inserted into the adapter 8 with the adapter 8 attached. Specifically, the disinfection mechanism 75 is configured to disinfect at least a portion of the outer surface of the ultrasonic probe. As an example, the disinfection mechanism 75 is configured to disinfect at least one of the head and the grip of the outer surface of the ultrasonic probe 20.

[0094] As an example, the sterilization mechanism 75a of the sterilization device 7 is configured to irradiate the outer surface of the ultrasound probe 20 with ultraviolet light UVL.

[0095] As an example, the sterilization mechanism 75b of the sterilization device 7 is configured to be able to generate ozone near the outer surface of the ultrasonic probe 20.

[0096] As an example, the disinfection mechanism 75c of the disinfection device 7 is configured to be able to wipe the outer surface of the ultrasonic probe 20 with a wiping member soaked in a disinfectant.

[0097] At least one of the disinfection mechanisms 75 may be configured to disinfect the ultrasonic probe 20 through the inner wall 802. Fig. 5 illustrates a case where the disinfection mechanism 75c is also mounted on the adapter 8. Specifically, Fig. 5 illustrates a case where the disinfection mechanism 75a irradiates the head of the ultrasonic probe 20 with ultraviolet light, the disinfection mechanism 75b distributes ozone around the head and the grip, and the disinfection mechanism 75c provided on the inner wall 802 wipes the grip portion with a disinfectant such as alcohol. In this case, the disinfection mechanism 75c provided on the inner wall 705 may be disabled.

[0098] The adapter 8 does not necessarily have to be provided with the disinfection mechanism 75.

[0099] When the adapter 8 is attached, the sterilization device 7 does not need to be provided with the rotation mechanism 73.

[0100] The transmission member of the rotation mechanism 73 may be provided at a position that contacts the outer surface of the ultrasonic probe 20 when the adapter 8, into which the ultrasonic probe 20 is inserted, is attached to the sterilization device 7. Alternatively, the adapter 8 may have an adapter-side transmission member that is provided at a position that contacts the outer surface of the ultrasonic probe 20 when the ultrasonic probe 20 is inserted. In this case, the adapter-side transmission member may be configured to be able to transmit power between the adapter 8 and the transmission member of the rotation mechanism 73 when the adapter 8 is attached to the sterilization device 7. According to these configurations, the ultrasonic probe 20 can be rotated by the rotation mechanism 73. Alternatively, the rotation mechanism 73 can detect at least one of the amount and direction of rotation of the ultrasonic probe 20.

[0101] The adapter 8 may be configured to be rotatably attached to the sterilization device 7. In this case, the rotation mechanism 73 may be configured to rotate the adapter 8.

[0102] The sterilization apparatus 7 or the adapter 8 according to this embodiment may be equipped with a sensor configured to measure at least one of the amount and direction of rotation of the ultrasonic probe 20. As the sensor, for example, an optical sensor that optically measures at least one of the amount and direction of rotation can be used.

[0103] In the detection function 711, the processing circuit 71 detects the attachment state of the adapter 8 to the sterilization device 7 based on the output of the detection circuit 77. Specifically, when the detection circuit 77 is a switch that turns on in the attachment state, the processing circuit 71 detects that the adapter 8 is attached to the sterilization device 7 in response to detecting a signal from the detection circuit 77.

[0104] In the disinfection control function 712, the processing circuit 71 starts disinfection of the ultrasonic probe 20 by the disinfection mechanism 75 when attachment of the adapter 8 is detected. The processing circuit 71 ends disinfection of the ultrasonic probe 20 by the disinfection mechanism 75 when the ultrasonic probe 20 is rotated a predetermined amount or more, for example, by an operator. Here, the threshold amount of rotation is an amount of rotation equal to or greater than an amount of rotation estimated to result in at least one rotation. For example, when the ultrasonic probe 20 is rotated by the rotation mechanism 73, the processing circuit 71 can acquire the amount of rotation of the trackball 51 in each rotation direction by each of the rotation mechanisms 73a and 73b.

[0105] In the notification function 713, the processing circuit 71 notifies the operator of at least one of the start and end of disinfection of the ultrasonic probe 20 by the disinfection mechanism 75 using the indicator 79. The processing circuit 71 monitors the attachment state of the adapter 8 based on the output of the detection circuit 77, and may notify the operator to correct the attachment state when the attachment state becomes inappropriate for disinfection.

[0106] In this way, the disinfection device 7 according to this embodiment is configured to be able to disinfect not only the trackball 51 but also the ultrasonic probe 20 by attaching the adapter 8. With this configuration, it is not necessary to prepare a disinfection device 7 for each object to be disinfected, which simplifies the disinfection work.

[0107] (Third embodiment) The disinfection device 7 according to the embodiment may be configured to be able to detect the type of the attached adapter 8.

[0108] As an example, the shape of the connecting portion of the adapter 8 with the sterilizer 7 differs depending on the type of adapter 8. For example, the mounting member 703 of the sterilizer 7 is provided with a plurality of recesses, each recess being provided with a detection circuit 77. In this case, in the detection function 711, the processing circuit 71 detects the type of the attached adapter 8, i.e., the type of ultrasonic probe 20 to be sterilized, based on which recess the detection circuit 77 provided in detects the adapter 8.

[0109] As an example, the adapter 8 has a memory that stores information indicating the type of the adapter 8. The adapter 8 may be provided with a barcode or two-dimensional code that indicates the type of the adapter 8. In this case, the sterilization device 7 is configured to be able to read the information stored in the memory via a wired or wireless connection. In the detection function 711, the processing circuit 71 detects the type of the attached adapter 8, i.e., the type of the ultrasonic probe 20 to be sterilized, based on the read information.

[0110] As an example, the sterilization device 7 has an input interface that accepts operation input from an operator. Based on the operation input from the operator specifying the type of adapter 8, the sterilization device 7 detects the type of the attached adapter 8, i.e., the type of the ultrasonic probe 20 to be sterilized.

[0111] In the disinfection control function 712, the processing circuit 71 determines the disinfection content to be performed by the disinfection mechanism 75 depending on the type of the attached adapter 8. The relationship between the type of adapter 8 and the disinfection content is assumed to be predetermined and stored in a memory provided in the disinfection device 7, for example.

[0112] According to this configuration, it is possible to change the threshold value of the rotation amount and time for sterilization completion, or to change the sterilization mechanism 75 to be operated, depending on the type of ultrasonic probe 20 to be sterilized, i.e., its surface area and shape, and the area to be sterilized. In other words, the sterilization device 7 according to this embodiment enables sterilization suited to the object to be sterilized.

[0113] (Fourth embodiment) The disinfection device 7 and the adapter 8 according to the embodiment may be integrally formed. That is, the disinfection device 7 according to the first embodiment may be configured to disinfect the ultrasonic probe 20 instead of the trackball 51.

[0114] Even with this configuration, the same effects as those of the above-described embodiment can be obtained.

[0115] (Fifth embodiment) In the disinfection system 9 according to the above embodiment, the ultrasonic diagnostic device 1 may be configured to operate in conjunction with the disinfection device 7. Specifically, the operator may be notified by the display 30 of the ultrasonic diagnostic device 1 in addition to or instead of the indicator 79. Differences from the first embodiment will be mainly described below.

[0116] Fig. 6 is a block diagram showing another example of the configuration of the disinfection system 9 according to the embodiment. As shown in Fig. 6, the ultrasonic diagnostic apparatus 1 and the disinfection apparatus 7 are connected to each other so as to be able to communicate with each other via wire or wirelessly.

[0117] In the notification function 713 according to this embodiment, the processing circuitry 71 notifies the ultrasonic diagnostic device 1 of at least one of the start and end of disinfection of the object by the disinfection mechanism 75, in addition to or instead of the indicator 79. Specifically, when disinfection of the object by the disinfection mechanism 75 starts, the processing circuitry 71 transmits a signal to the ultrasonic diagnostic device 1 to cause the display 30 of the ultrasonic diagnostic device 1 to display information indicating the start of disinfection. Alternatively, when disinfection of the object by the disinfection mechanism 75 ends, the processing circuitry 71 transmits a signal to the ultrasonic diagnostic device 1 to cause the display 30 of the ultrasonic diagnostic device 1 to display information indicating the completion of disinfection. In other words, the processing circuitry 71 of the disinfection device 7 according to this embodiment causes the display 30 of the ultrasonic diagnostic device 1 to display at least one of the start and end of disinfection of the object by the disinfection mechanism 75, in addition to or instead of the indicator 79.

[0118] In the ultrasound diagnostic device 1, the ultrasound probe 20, the display 30, and the input interface 50 are connected to the device main body 10 so as to be able to communicate with each other.

[0119] 1, the device main body 10 has a transmission / reception circuit 110, a buffer memory 120, a signal processing circuit 130, an image generation circuit 140, a storage circuit 150, a network (NW) interface 160, and a processing circuit 170. The transmission / reception circuit 110, the buffer memory 120, the signal processing circuit 130, the image generation circuit 140, the storage circuit 150, the NW interface 160, and the processing circuit 170 are connected to each other so as to be able to communicate with each other.

[0120] The transmission / reception circuit 110 includes a pulse generator, a transmission delay unit, a pulser, etc., and supplies a drive signal to the ultrasonic probe 101. The pulse generator repeatedly generates rate pulses at a predetermined rate frequency to form transmitted ultrasonic waves. The transmission delay unit focuses the ultrasonic waves generated from the ultrasonic probe 101 into a beam and provides a delay time for each transducer 101a required to determine the transmission directivity to each rate pulse generated by the pulse generator. The pulser applies a drive signal (drive pulse) to the ultrasonic probe 101 at a timing based on the rate pulse. In other words, the transmission delay unit changes the delay time provided to each rate pulse to arbitrarily adjust the transmission direction of the ultrasonic waves transmitted from the transducer surface.

[0121] The transmission / reception circuit 110 also includes a preamplifier, an A / D (Analog to Digital) converter, a quadrature detection circuit, etc., and performs various processes on the reflected wave signal received by the ultrasonic probe 101 to generate reflected wave data.

[0122] The preamplifier amplifies the reflected wave signal for each channel and performs gain adjustment (gain correction). The A / D converter converts the gain-corrected reflected wave signal into a digital signal by A / D converting it. The quadrature detection circuit converts the A / D converted reflected wave signal into an in-phase signal (I signal, I: In-phase) and a quadrature signal (Q signal, Q: Quadrature-phase) in the baseband.

[0123] The quadrature detection circuit outputs an I signal and a Q signal as reflected wave data. Hereinafter, the I signal and the Q signal will be collectively referred to as an IQ signal. Furthermore, since the IQ signal is A / D converted digital data, it is also called IQ data.

[0124] The buffer memory 120 is realized by a semiconductor memory element such as a RAM, a flash memory, etc. The buffer memory 120 stores the reflected wave data output from the transmission / reception circuit 110.

[0125] The signal processing circuit 130 acquires the reflected wave data stored in the buffer memory 120. The signal processing circuit 130 also performs logarithmic amplification, envelope detection processing, etc. on the reflected wave data acquired from the buffer memory 120 to generate data (B-mode data) in which signal intensity is expressed as brightness of luminance. The signal processing circuit 130 also performs frequency analysis on velocity information from the reflected wave data acquired from the buffer memory 120, extracts blood flow, tissue, and contrast agent echo components due to the Doppler effect, and generates data (Doppler data) in which moving object information such as velocity, dispersion, and power is extracted for multiple points.

[0126] The signal processing circuit 130 can process both two-dimensional reflected wave data and three-dimensional reflected wave data. That is, the signal processing circuit 130 generates two-dimensional B-mode data from the two-dimensional reflected wave data, and generates three-dimensional B-mode data from the three-dimensional reflected wave data. The signal processing circuit 130 also generates two-dimensional Doppler data from the two-dimensional reflected wave data, and generates three-dimensional Doppler data from the three-dimensional reflected wave data.

[0127] The image generation circuit 140 generates an ultrasound image from the data generated by the signal processing circuit 130. For example, the image generation circuit 140 generates a two-dimensional B-mode image from the two-dimensional B-mode data generated by the signal processing circuit 130, in which the intensity of the reflected wave is represented by brightness.

[0128] Furthermore, for example, the image generation circuit 140 generates a two-dimensional Doppler image in which blood flow information is visualized from the two-dimensional Doppler data generated by the signal processing circuit 130. The two-dimensional Doppler image is velocity image data representing the average velocity of the blood flow, variance image data representing the variance of the blood flow, power image data representing the power of the blood flow, or image data combining these. Furthermore, the image generation circuit 140 generates a color Doppler image in which blood flow information such as the average velocity, variance, and power of the blood flow are displayed in color, or a Doppler image in which one piece of blood flow information is displayed in grayscale.

[0129] Furthermore, for example, the image generating circuit 140 can also generate an M-mode image from time series data of B-mode data on one scanning line generated by the signal processing circuit 130. Furthermore, the image generating circuit 140 can also generate a Doppler waveform in which velocity information of blood flow and tissue is plotted in time series from the Doppler data generated by the signal processing circuit 130.

[0130] Here, the image generation circuit 140 generally converts (scan converts) a scan line signal sequence of an ultrasound scan into a scan line signal sequence of a video format, such as that of a television, to generate an ultrasound image for display. Specifically, the image generation circuit 140 generates an ultrasound image for display by performing coordinate conversion according to the ultrasound scanning format of the ultrasound probe 101. In addition to scan conversion, the image generation circuit 140 also performs various image processing, such as image processing (smoothing processing) that regenerates an average brightness image using multiple image frames after scan conversion, and image processing (edge ​​enhancement processing) that uses a differential filter within the image. The image generation circuit 140 also combines text information of various parameters, scales, body marks, etc. with the ultrasound image data.

[0131] That is, the B-mode data and Doppler data are data before scan conversion processing, and the data generated by the image generation circuit 140 is image data for display after scan conversion processing. Hereinafter, the data before scan conversion processing (B-mode data and Doppler data) will also be referred to as "RAW data."

[0132] The image generation circuit 140 generates a two-dimensional ultrasound image, such as a two-dimensional B-mode image or a two-dimensional Doppler image, from the two-dimensional B-mode data or two-dimensional Doppler data, which are raw data. The image generation circuit 140 can also generate a superimposed image, for example, by superimposing a color Doppler image on a two-dimensional B-mode image.

[0133] In addition, the image generating circuit 140 generates a notification screen that notifies the user of the status of the sterilization device 7.

[0134] The memory circuitry 150 stores various types of data. For example, the memory circuitry 150 stores control programs for transmitting and receiving ultrasound, image processing, and display processing, as well as various types of data such as diagnostic information (e.g., patient ID, doctor's findings, etc.), diagnostic protocols, and various body marks. For example, the memory circuitry 150 is realized by a semiconductor memory element such as a RAM or flash memory, a HDD, an optical disk, etc.

[0135] The data stored in the memory circuitry 150 can be transferred to an external device via the NW interface 160. The external device may be, for example, a personal computer (PC) or tablet terminal used by a doctor who performs image diagnosis, an image storage device that stores images, a printer, or the like.

[0136] The NW interface 160 controls communication between the device main body 104 and an external device. Specifically, the NW interface 160 receives various information from the external device and outputs the received information to the processing circuit 170. For example, the NW interface 160 is realized by a network card, a network adapter, a NIC (Network Interface Controller), or the like.

[0137] The processing circuitry 170 controls the overall processing of the ultrasound diagnostic apparatus 100. Specifically, the processing circuitry 170 controls the processing of the transmission / reception circuitry 110, the signal processing circuitry 130, and the image generation circuitry 140 based on various setting requests input by the operator via the input interface 102 and various control programs and various data read from the storage circuitry 150. The processing circuitry 170 also controls the display of ultrasound images. For example, the processing circuitry 71 has a processor and a memory as hardware resources.

[0138] 6, the processing circuit 170 is configured to realize the interlocking function 171. Note that the interlocking function 171 is not limited to being realized by a single processing circuit. The processing circuit may be configured by combining multiple independent processors, and the interlocking function 171 may be realized by each processor executing a program.

[0139] The term "processor" used in the above description refers to a circuit such as a CPU, a GPU, an ASIC, a SPLD, a CPLD, or an FPGA.

[0140] Various processing functions executed by the processing circuitry 170 are stored in the storage circuitry 150 in the form of programs executable by a computer. The processing circuitry 170 realizes the functions corresponding to each program by reading the program from the storage circuitry 150 and executing it using a processor. In other words, each circuit that has read each program has the function corresponding to the read program.

[0141] In the interlocking function 171, the processing circuit 170 displays information indicating the start of disinfection or information indicating the completion of disinfection on the display 30 in response to a signal from the disinfection device 7.

[0142] Next, we will explain the processing executed by the ultrasonic diagnostic device 1. Figure 7 is a diagram showing an example of the flow of processing executed in the ultrasonic diagnostic device 1 of Figure 6. Here, we will also explain the relationship with the processing executed in the disinfection device 7 of Figure 4.

[0143] In the interlocking function 171, the processing circuit 170 determines whether or not a notice of disinfection start has been received from the disinfection device 7 (S201). If it is determined that a notice of disinfection start has not been received from the disinfection device 7 (S201: No), the flow in Fig. 7 repeats the process of S201 at predetermined time intervals, for example, until it is determined that a notice of disinfection start has been received from the disinfection device 7.

[0144] In the process of S102, the processing circuit 71 of the sterilization device 7 further notifies the ultrasonic diagnostic device 1 of the start of sterilization. Then, when it is determined that the notification of the start of sterilization has been received from the sterilization device 7 (S201: Yes), the processing circuit 170 in the interlocking function 171 disables the operation input by the trackball 51 (S202).

[0145] At this time, the processing circuit 170 may display on the display 30 a notification screen indicating that disinfection of the trackball 51 by the disinfection device 7 has started. In addition, the processing circuit 170 may display on the display 30 a notification screen indicating that the operation input by the trackball 51 has been invalidated.

[0146] Note that, in cases where the trackball 51 is disinfected between examinations, for example, the operational input of the trackball 51 may already be invalidated, so the processing of S202 is not essential.

[0147] In addition, in the interlocking function 171, the processing circuit 170 determines whether or not a notice of disinfection completion has been received from the disinfection device 7 (S203). If it is not determined that a notice of disinfection completion has been received from the disinfection device 7 (S203: No), the flow in Fig. 7 repeats the process of S203, for example, at predetermined time intervals, until it is determined that a notice of disinfection completion has been received from the disinfection device 7.

[0148] In the process of S105, the processing circuit 71 of the disinfection device 7 further notifies the ultrasonic diagnostic apparatus 1 of the disinfection completion. Then, when it is determined that the disinfection completion notification has been received from the disinfection device 7 (S203: Yes), the processing circuit 170 in the interlocking function 171 displays a notification screen including a disinfection completion notification indicating that the disinfection of the trackball 51 by the disinfection device 7 has been completed on the display 30. Then, the flow in FIG. 7 ends.

[0149] The notification screen may include a notification indicating that the operation input by the trackball 51 has been validated.

[0150] In the present embodiment, the trackball 51 is sterilized, but the present invention is not limited to this. The technology according to the present embodiment can also be applied to cases where the ultrasonic probe 20 is sterilized.

[0151] In this way, when disinfection of an object by the disinfection mechanism 75 is completed, the disinfection apparatus 7 according to this embodiment displays information indicating the completion of disinfection on the display 30 of the ultrasound diagnostic apparatus 1. This configuration allows the operator to easily grasp the completion of disinfection, and therefore allows the operator to quickly move on to the next examination upon completion of disinfection, thereby improving the throughput of examinations.

[0152] Furthermore, the disinfection device 7 according to the embodiment disables cursor movement accompanying the rotation of the trackball 51 when disinfection of the trackball 51 by the disinfection mechanism 75 starts. This configuration makes it possible to prevent cursor movement on the display 30 of the ultrasound diagnostic device 1 accompanying the disinfection operation. Therefore, even if the trackball 51 is enabled between examinations, unnecessary cursor movement can be prevented.

[0153] In the disinfection system 9 according to each of the above-described embodiments, the disinfection device 7 may receive power supply from the ultrasonic diagnostic device 1. This power supply may be realized by a wired connection such as a USB, or may be realized by wireless power supply. Note that the ultrasonic diagnostic device 1 may be configured to be able to supply power wirelessly to the disinfection device 7 when the disinfection device 7 is attached to a position on the trackball 51 suitable for disinfection. In other words, the attachment position of the disinfection device 7 may be determined by the position of the disinfection device 7 that can be wirelessly powered.

[0154] According to at least one of the embodiments described above, the disinfection process can be simplified.

[0155] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are intended to be included within the scope and spirit of the invention, as well as within the scope of the inventions and their equivalents as defined in the claims.

[0156] With respect to the above embodiment, the following supplementary notes are disclosed as one aspect and optional features of the invention.

[0157] (Appendix 1) a mounting member formed so as to be mountable on an object to be disinfected so as to cover the object; a disinfection mechanism configured to be able to disinfect the object while attached to the object; a detection circuit configured to detect attachment to the object; a control unit configured to start disinfection of the object by the disinfection mechanism when attachment of the device to the object is detected based on an output of the detection circuit; and A disinfection device comprising:
