Description

Technical Field

[0001] The present invention relates to a guiding device for completing a disinfection operation in a short time, a disinfection device capable of completing a disinfection operation in a short time, and a disinfection method using the disinfection device.

Background Art

[0002] In the prevention and management of infectious diseases, hand disinfection is an extremely important measure, and hand disinfection with an alcohol disinfectant is recommended by international guiding organizations in this field such as the WHO (World Health Organization) and the CDC (Centers for Disease Control (and Prevention)). However, although hand disinfection with an alcohol disinfectant is the simplest hand disinfection method, its compliance rate is very low. According to the observation results of a certain study, the hand hygiene compliance rate of medical staff (doctors and nurses) before contacting patients was as low as 19% (Non-Patent Documents 1 and 2). Regarding the amount of disinfectant used, the CDC and WHO guidelines stipulate that "if the hands feel dry after rubbing for 10 - 15 seconds, the application amount is insufficient." Also, the WHO guidelines recommend performing the rubbing method shown in Figure - 1 for 20 - 30 seconds (Non-Patent Document 3). In fact, in a 2015 questionnaire conducted by an alcohol disinfectant manufacturer for medical institutions regarding the "regulations on the amount of alcohol disinfectant used per application and the rubbing time," among the institutions that stipulate the amount of disinfectant used, for the liquid type, 3 ml or more accounted for 24% and was the most common, followed by 2.5 ml - 3 ml at 15%. For the gel type, 2 ml or more accounted for 16%, 1.5 ml - 2 ml accounted for 14%, and 1 - 1.5 ml accounted for 10%. Among the institutions that stipulate the rubbing time, regardless of the liquid type or gel type, 15 seconds or more was the most common (15% and 21% respectively), followed by 20 - 30 seconds or more (7% and 9% respectively) (Non-Patent Document 4). Under these circumstances, various disinfection devices and disinfection methods that can complete the disinfection process in as short a time as possible have been proposed. For example, it has been found that ultraviolet rays in the range of 190 nm to 230 nm have little impact on the human body and yet exhibit a high sterilization effect (Non-Patent Document 5, etc.), and multiple proposals applying this finding have been made. For example, in Patent Documents 1 to 3 and 5, disinfection devices for the human body using ultraviolet rays in the range of 190 nm to 230 nm have been proposed. Further, in Patent Document 4, a disinfection method combining ultraviolet rays and a bactericide has been proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the disinfection device and disinfection method according to the above proposal, there is still a problem that the disinfection process takes a long time, and there are also problems with the wavelength of ultraviolet rays (Patent Document 4), and the problem of skin roughness has not been solved from the perspective of the disinfection process time. From this perspective, the present inventors have proposed a disinfection device that effectively combines ultraviolet rays in the range of 190 nm to 230 nm and an alcohol-based disinfectant (Patent Documents 6 and 7). Although such a proposal contributes to finger disinfection in a short time, the methods of disinfection treatment vary among users, and as a result, the disinfection treatment time often takes a long time. In short, in the conventional proposals, the problems of performing disinfection treatment quickly, maximizing the disinfection effect, and minimizing the impact on the human body such as skin roughness have not been sufficiently solved at present. Therefore, there is a current demand for the development of a disinfection device and a disinfection method that can stably complete the disinfection treatment in a short time regardless of the user. Therefore, an object of the present invention is to provide a disinfection device and a disinfection method that can easily and stably disinfect fingers in a short time and have less adverse effects on the human body such as skin roughness.

Means for Solving the Problems

[0006] As a result of intensive studies to solve the above problems, the inventors have found that when performing an appropriate disinfection operation, a high disinfection effect may be obtained even when the disinfection treatment is performed for about 10 seconds. As a result of further studies, it has been found that the above object can be achieved by providing a guide device for guiding the disinfection treatment in a disinfection device, and the present invention has been completed. That is, the present invention provides the following inventions. 1. A guide device for guiding the rubbing operation of a disinfectant into a user's finger, which emits an auditory signal and / or a visual signal at a specific speed, rhythm, and time, and is configured such that the user can perform the rubbing operation according to the signal. A guide device for finger disinfection, characterized in that. 2. A disinfection device including a disinfectant supply unit for supplying a disinfectant to a user's finger and a guide unit for guiding the rubbing operation of the disinfectant into the finger of the user, wherein the guide unit is configured by the guide device according to 1. A disinfection device, characterized in that. 3. Further, the disinfection device according to 2, characterized in that it further includes an ultraviolet irradiation unit for irradiating ultraviolet rays having a wavelength of 190 nm to 230 nm to the finger of the user. 4. Further, the disinfection device according to 2, comprising a sensor for detecting that the user has inserted a finger below a disinfectant discharge nozzle, and a control unit for operating the disinfectant supply unit and the guide unit when the sensor detects the finger. 5. A finger insertion space for the disinfectant supply unit to supply a disinfectant to the user's finger and for the ultraviolet irradiation unit to irradiate ultraviolet rays to the user's finger, a sensor for detecting that the user has inserted a finger into the finger insertion space, and a control unit for operating the disinfectant supply unit, the ultraviolet irradiation unit, and the guide unit when the sensor detects the finger. The disinfection device according to 3, comprising: 6. A finger disinfection method characterized by performing finger disinfection according to the guidance of the guide device according to 1.

Effect of the Invention

[0007] According to the disinfection method and disinfection device of the present invention, fingers can be easily and stably disinfected in a short time, and there are few adverse effects on the human body such as skin roughness. Specifically, by adjusting the guiding speed of the guiding device, the speed of rubbing in the disinfectant can be increased compared to the conventional methods recommended by the WHO and the like, and the disinfectant can be rubbed into the entire surface of the finger in a short time. For this reason, the treatment with the disinfectant can be carried out so that the disinfection effect by the disinfectant is maximally exerted, and the amount of the disinfectant used can also be reduced, and the adverse effects on the human body such as skin roughness can be further reduced. Therefore, the disinfection method and disinfection device of the present invention are particularly suitable for the hygienic (academic) finger hygiene of medical staff, and are more suitable for use in hospitals and the like where there are a large number of medical staff. Further, by using ultraviolet irradiation in combination, the disinfection effect by the disinfectant can be further improved, and the amount of the disinfectant used can be further reduced.

Embodiment for Carrying out the Invention

[0010] Hereinafter, the present invention will be described more specifically, but the present invention is not limited thereto at all. <Guide Device and Disinfection Device (First Disinfection Device)> First, a first embodiment of the disinfection device of the present invention will be described, and a guide device used in the disinfection device of the present invention will be described. As shown in FIGS. 1(a) and (b), the disinfection device 1 of the present embodiment includes a finger disinfection guide device 20 as a guide part for guiding the user to rub the disinfectant into the fingers, and a disinfectant supply unit 10 for supplying the disinfectant to the user's fingers, and can disinfect the user's fingers with the disinfectant. The following will be described in more detail.

[0011] 〔Disinfection Device〕 As shown in FIGS. 1(a) and (b), the disinfection device 1 of the present embodiment includes a box-shaped device body 3, a disinfectant supply unit 10 housed in the device body 3, and a guide device 20 installed on the outer surface and inside of the device body 3. 〔Device Body〕 The device body 3 has a hollow rectangular parallelepiped shape, and an opening 5 for protruding a nozzle 11a constituting the disinfectant supply unit 10 is provided at the center of the front surface. Below the opening 5, a sensor 7 for detecting that the user has brought the finger close to a predetermined position directly below the nozzle 11a for using the disinfection device is provided. This sensor 7 constitutes a part of the disinfectant supply unit 10 and also constitutes a part of the guide device 20.

[0012] 〔Disinfectant Supply Unit〕 As shown in FIGS. 1(a) and (b), the disinfectant supply unit 10 includes a push-type pump dispenser 11 having a nozzle head 11b with a nozzle 11a protruding from an opening 5, a disinfectant container 13 filled with a disinfectant in which the pump dispenser 11 is mounted, a cantilever 15 for pushing down the nozzle head 11b, and a drive mechanism 17 for supplying power to the cantilever. The drive mechanism 17 is driven by being supplied with power from a battery 19, transmits power in the pushing-down direction of the nozzle head 11b to the cantilever 15, pushes down the cantilever 15, and discharges a predetermined amount of disinfectant from the nozzle 11a.

[0013] Further, the drive mechanism 17 is connected to a sensor 7 that detects that the user has placed a finger below the disinfectant discharge nozzle (including the case of stopping in the air), and is configured such that the operation of the drive mechanism 17 is driven when a signal from the sensor is received. The device configuration of the drive mechanism 17 is not particularly limited, and a device configuration employed in a drive mechanism for pushing down this type of dispenser bottle can be used. It is desirable that the time required for one discharge of the disinfectant supplied from the disinfectant supply unit 10 be as short as possible, desirably 2 seconds or less, preferably 1 second or less, from the detection by the sensor to the completion of the discharge. When the adhesion of the disinfectant to the palm of the hand or the like of the user is completed, the user disinfects by rubbing the disinfectant into the finger for a predetermined time, in an appropriate method, and at a rhythm according to the guide of the guide device 20 of the rubbing operation of the disinfectant into the finger. Details will be described later. The amount of disinfectant discharged once from the nozzle 11a is preferably 1.2 ml to 2.2 ml, more preferably 1.3 to 1.7 ml.

[0014] 〔Disinfectant〕 As the disinfectant used in the disinfection device of this embodiment, a quick-drying alcohol-based disinfectant mainly composed of an aqueous solution of ethanol, propanol, or a mixture of both, an alcoholic solution of iodine (tincture of iodine), an iodine-based disinfectant mainly composed of an alcoholic solution of povidone iodine (a complex of polyvinylpyrrolidone and iodine), a quaternary ammonium salt-based disinfectant mainly composed of an alcoholic solution of benzalkonium chloride and benzethonium chloride; an amphoteric surfactant-based disinfectant mainly composed of an alcoholic solution of alkyldiaminoethyl glycine hydrochloride, a biguanide-based disinfectant mainly composed of an alcoholic solution of chlorhexidine gluconate, etc. can be used. Among these, a quick-drying alcohol-based disinfectant mainly composed of an aqueous solution of ethanol, propanol, or a mixture of both is most preferable in terms of disinfecting power, safety, quick-drying property, and the fact that water supply and drainage facilities are not required. The mixing ratio of water and alcohol in this aqueous solution preferably has an alcohol content of 50% by volume or more, more preferably 60% by volume or more. Also, it is preferably 95% by volume or less, more preferably 85% by volume or less. When the mixing ratio of alcohol is low, there is a tendency that a sufficient sterilization and disinfection effect cannot be achieved, and drying after application tends to be slow. On the other hand, when the mixing ratio of alcohol is high, a sufficient sterilization and disinfection effect cannot be achieved, drying becomes too fast, and there is a tendency that the irritation to the skin becomes stronger. The above alcohol-based disinfectant may contain a small amount of disinfectants such as benzalkonium chloride, benzethonium chloride, chlorhexidine gluconate, etc., and may also contain a small amount of thickeners such as carboxyvinyl polymer and cellulose-based water-soluble polymer compounds as needed. Also, a moisturizing agent for preventing rough hands, etc. can be included. The alcohol-based disinfectant used in the present invention preferably has characteristics such as being able to be supplied from the disinfectant container to the palm in a short time by a dispenser or a spraying device, the discharged liquid spreading within an appropriate range, and having good lubricity and being easy to rub into the entire surface of the fingers. To satisfy these characteristics, at least the kinematic viscosity of the disinfectant is preferably 2 to 5×10 3 mm 2 / s.

[0015] 〔Usage amount of disinfectant〕 As described above, regarding the usage amount and rubbing-in time of the disinfectant in one-time disinfection, conventionally, in order to obtain a high disinfection effect, a large amount of disinfectant has been used and it has been encouraged to rub it into the fingers for a long time. However, when aiming to complete a sufficient disinfection operation in a short time of less than 15 seconds, the direction is different. If a large amount of disinfectant of 3 ml or more is used, it takes more than 30 seconds for all the disinfectant to volatilize. Even if the disinfection itself is achieved in a short time, the fingers do not dry and it prevents the disinfection subject from moving on to the next operation. In addition, using a large amount of disinfectant tends to cause rough skin. On the other hand, if the amount of disinfectant is too small, there is a problem that the disinfectant volatilizes before it can exert its effect. Therefore, in order to obtain a sufficient disinfection effect in a short time using an alcohol disinfectant, it is extremely important to use an appropriate amount of disinfectant and quickly rub it into the entire surface of the finger before it volatilizes. The amount of disinfectant is preferably 1 ml or more and less than 3 ml, more preferably 1.2 ml to 2.2 ml, and most preferably 1.3 to 1.7 ml.

[0016] 〔Guide device〕 The above guide device has an auditory guide means that emits an auditory signal and a visual guide means that emits a visual signal. Specifically, the guide device 20 has a function of guiding the operation of rubbing the disinfectant into the finger described above. In this embodiment, the rubbing rhythm of the finger is shown visually and auditorily by sound, which is an auditory signal, and light, which is a visual signal, that is, it is constituted by an electronic metronome (indicated by reference numeral 20 in FIG. 1), which is both an auditory guide means and a visual guide means. Further, it includes a control device (not shown) and a sensor 7 electrically connected to the control device. The above electronic metronome includes a sound-emitting part (not shown) and a pair of left and right light-emitting parts 21, 23 that can blink. Note that the above guide device does not necessarily have both an auditory guide means that emits an auditory signal and a visual guide means that emits a visual signal, and either one may be sufficient. Although not particularly shown, the control device can be configured by a so-called computer including a random access memory (RAM), at least one central processing unit (CPU), and a recording medium. As this computer, a so-called small microcomputer is preferable. And a program described later is stored in this computer to guide the user through the disinfection process. The electronic metronome in the guide device 20 receives the detection signal from the sensor 7 and is automatically controlled in conjunction with the drive of the disinfectant supply unit by the control device. The guide device 20 preferably guides the above-mentioned user so that the disinfection operation can be completed in less than 15 seconds, and more preferably guides the user so that the disinfection operation can be completed in less than 10 seconds.

[0017] 〔Guide for the operation of rubbing in the disinfectant by the guide device〕 In order to sufficiently obtain the disinfection effect of the fingers with the disinfectant, it is important to rub the disinfectant into the entire surface of the finger. In the conventional method of rubbing in the disinfectant such as the WHO method, nine types of rubbing-in methods corresponding to each part of the finger are each performed five times, so the total number of rubbing-in operations is 45 times. Since the speed of the rubbing-in operation is about 100 times per minute, the time required for disinfection is less than 30 seconds. The present invention is based on the finding that a high disinfection effect may be obtained even when the disinfection process is performed in about 10 seconds by performing an appropriate disinfection operation. That is, based on the knowledge that a high disinfection effect can be easily obtained by rubbing the disinfectant into the fingers at high speed and in a short time in the correct method according to the guidance of the guide device, by having the guide device, preferably the finger disinfection time can be completed within less than 15 seconds, and more preferably within 10 seconds. For that purpose, it is most important to increase the rubbing operation speed, and furthermore, it is conceivable to reduce the number of rubbing operations. Regarding the latter, it is necessary to reduce the types of rubbing methods and adopt methods that are easy to perform the rubbing operation. The number of types of rubbing methods is at least 9 or less, preferably 6. Also, regarding the number of operations, it is preferable to rub 2 or more times for the number of rubbing times in one rubbing method. The disinfection treatment, that is, the method of rubbing the disinfectant into the fingers during disinfection, will be further described later.

[0018] When performing a rubbing operation at a high operating speed using a conventional disinfection device, users may not necessarily be able to perform the rubbing operation at a desired speed, and it is difficult for all users to perform the rubbing operation at the same high level. This becomes an even more serious problem when a large number of users, such as in a hospital, need to perform finger disinfection at the same high level. In the present invention, as a means for various users to perform a rubbing operation at a high operating speed, there is a guide device for guiding the rubbing operation, so that various users can perform the rubbing operation of the disinfectant at the same high operating speed. Specifically, the guide device guides the user by sound and / or light like a metronome. That is, the user performs the rubbing operation according to the auditory signal and / or visual signal emitted from the guide device. The types of the auditory signal and / or visual signal are not particularly limited, but for the auditory signal, various so-called metronome-like sounds, such as the sound of a xylophone, the sound of a piano, an electronically synthesized sound, a human voice, etc. can be used. As the human voice, a call such as "one, two" may be used. For the visual signal, visible light emitted from various LEDs and lamps can be used, and the signal is displayed by the blinking of the light or the change of the emission color. It is also possible to display the rubbing operation itself as a moving image on the screen of a display device such as a liquid crystal or an organic EL, or to display the blinking of the light and the change of the color by a still image. The signal can be emitted at a constant speed, at a constant interval, or at a constant tempo like a metronome, and the speed, interval, and tempo can also be changed gradually or from the middle. The user performs the rubbing operation according to these signals. Usually, one rubbing operation is performed in response to one beat of the signal. In the case of the rubbing method described later, the rubbing operation can be performed smoothly with two beats (strong and weak). Therefore, for the sound, the first beat is made strong and the second beat is made weak (e.g., cut, con), and for the light, it is conceivable to change the color, such as making the first beat blue and the second beat yellow. At this time, the speed of the signal (the number of signals per minute) is preferably higher than 100 times / min and less than 180 times / min. If the speed is 100 times / min or less, it is difficult to complete the disinfection in a short time, or the disinfectant volatilizes during the rubbing and cannot be used effectively. If it is 180 times / min or more, the rubbing operation becomes unstable and it is difficult to stably rub the disinfectant over the entire surface of the finger.The disinfection time is determined by the speed and the number of signal generations. If an appropriate rubbing speed is used, disinfection can be achieved in a short time. For example, if the speed is 144 times per minute and the number of rubbings is 24 times, disinfection can be achieved in 10 seconds. When there is no disinfection guide signal, the user usually performs the rubbing operation at a speed slower than the speed required to complete disinfection in a short time of less than 15 seconds. Therefore, sufficient rubbing of the disinfectant cannot be achieved in a short time, resulting in insufficient disinfection. Also, in hospitals with many nurses, it is difficult to keep the disinfection level constant because the disinfection speed varies from person to person. By using this guide device, the finger disinfection level can be maintained at a consistently high value in a short time. Note that the length of the sound emission and the lighting time of the light are each lengths that can satisfy the above-mentioned number of generations per minute. By setting the number of times of the sound and light of the guide device to appropriate values, finger disinfection is possible within a disinfection time of less than 15 seconds, and more preferably, disinfection within 10 seconds or less is also possible.

[0019] 〔Control Device and Control Program〕 The control device is configured by a computer as described above, and a control program for controlling the disinfection device of the present embodiment is stored in the recording medium. By this control program, instructions are given to the disinfectant supply unit 10 and the guide device 20 to control the entire disinfection device. Regarding the control program, the control program of the present embodiment consists of a detection step S010, a supply step S020, a guide step S030, and an end instruction S040, as shown in FIG. 2. (Detection Step S010) This step is a step of grasping that the user's finger is placed at a predetermined position directly below the disinfectant supply nozzle when a signal from the sensor 7 is received. In this step, if it is sensed that the user's finger has reached the predetermined position directly below the disinfectant supply nozzle, it is immediately grasped as "use" in step S020. (Supply Step S020) This step is to issue a driving instruction to supply the disinfectant to the driving mechanism 17 in the disinfectant supply unit 10. When it is determined as "to be used" in the detection step, an instruction is issued to start the driving mechanism 17. This instruction can be implemented by instructing to energize the switch terminal of the driving mechanism 17, and the driving mechanism 17 is started by energization to discharge the disinfectant liquid. From this perspective, it is preferable that the driving mechanism 17 incorporates controllable terminals such as known switch terminals. (Guide Step S030) This step is to receive the completion of the supply of the disinfectant, instruct the start of the guide, and instruct the end of the guide when the guide for a predetermined time is completed. The completion of the supply of the disinfectant can be set by various methods. In this embodiment, it is set to issue an instruction to start the guide as soon as the instruction to the driving mechanism 17 in the supply step is completed. And it is set to issue an instruction to end the guide after a predetermined time has elapsed since the start of the guide for a predetermined time. (End Instruction S040) This step is to convey to the user the completion of all disinfection processes. Since the end of the guide is instructed in the guide step, an instruction is issued to guide the user to the completion of the disinfection process by the above-described guide device 20 as the time for the start and end of the guide arrives. Specifically, by making both the sound different from that during the guide and the light-emitting parts 21, 23 emit light, etc., a visual and auditory display different from that during the guide is performed to notify the completion of the disinfection process.

[0020] <The First Embodiment of the Disinfection Method of the Present Invention (Disinfection Method Using the Disinfection Device of the First Embodiment)> The finger disinfection method of the present invention can be implemented by using the disinfection device of this embodiment equipped with the guide device of the above-described embodiment and performing finger disinfection according to the guidance of the guide device. The disinfection method of the present invention can be implemented such that the rubbing-in of the disinfectant on the entire finger surface is completed preferably within less than 15 seconds, more preferably within 10 seconds from the start of the disinfection process. The following will be specifically described. First, in order to rub the disinfectant into the fingers before it volatilizes in a short time, it is important to increase the above-mentioned rubbing speed and devise the rubbing method. Basically, it is preferable to rub the disinfectant into the entire surface of the finger. The WHO guidelines propose a method for rubbing in the disinfectant (see Non-Patent Document 3, Figure 4). In this embodiment, it is assumed that the rubbing is performed according to this rubbing method. Usually, this rubbing method requires 20 to 30 seconds to rub in the disinfectant.

[0021] In this embodiment, since the disinfection device of the present invention equipped with the above-mentioned guiding device of the present invention is used, by setting the setting of the guiding device, that is, the speed of the signal, preferably higher than 100 times / minute and less than 180 times / minute, the disinfectant can be rubbed into the entire finger within less than 15 seconds, and further within 10 seconds, and the disinfection of the finger can be completed. Particularly preferably, it is a method obtained by slightly improving the method proposed by the WHO. Specifically, each part of the finger is divided into four parts: the palm including the i-th finger, the side of the ii-th finger, the back of the hand, and the fingertip. First, as shown in A of Figure 4, after dropping the disinfectant on the upward cup-shaped palm, the rubbing into the finger is performed as follows. 1: Close the palm and cross the fingers and rub back and forth twice (Figure 4B). The method of crossing the right thumb inside the left thumb and the method of crossing the right thumb outside the left thumb are performed sequentially (Figure 4C). By this method, the disinfectant can be rubbed into most of the parts of i and ii. Since the rubbing operation is performed once in accordance with the sound and light of one beat, the two rubbings are performed in accordance with the sound and light of two beats. Since the rubbing operation can be performed smoothly with a two-beat (strong and weak) rhythm, it is conceivable to make the first beat strong and the second beat weak for the sound (e.g., ka, kon), and change the color such as making the first beat blue and the second beat yellow for the light. (The following is common to 1 to 4) 2: Rub the back of one hand with the fingers aligned with the palm of the opposite hand (Figure 4D, E). The back of the hand and the palm of the opposite hand are overlapped at a nearly right angle. The fingertips of the upper hand rub the outer surface of the little finger of the lower hand, the center of the upper hand rubs the back of the lower hand, and the thumb of the upper hand also rubs the side of the thumb of the lower hand. There are a right hand and a left hand. Thus, the disinfectant can be rubbed into i to iii. 3: Narrow the fingertips of one hand and rub the fingertips with the palm of the other hand (F, G in Fig. 4). This allows the alcohol-based disinfectant to be rubbed into i and iv. If 1 to 3 are performed sequentially, the disinfectant can be rubbed into all parts of the fingers of i to iv. With the settings of the guiding device, if the signal speed, that is, the rubbing-in speed, is 144 times / minute and the rhythm is 2 beats, and the rubbing-in is completed in 5 seconds, the rubbing-in of all parts of the fingers can be performed in 5 seconds. There are various rubbing-in methods other than 1 to 3, and it is not necessarily limited to these. It is preferable to rub the disinfectant into all parts of the fingers at least once, and more preferably to rub the alcohol-based disinfectant two or more times. In order to perform the rubbing-in on all parts of the fingers in a short time, it is preferable to adopt a rubbing-in operation in which two or more of the above-mentioned parts of i to iv are simultaneously rubbed in one rubbing-in operation. For example, among the operations of the WHO method, there are those that can only rub in one part in one operation, and such an operation is preferably replaced with another method that can rub two or more parts simultaneously. In any case, by performing disinfection using the above-mentioned disinfection device, the disinfection process can be completed in a shorter time compared to the conventional method. That is, the disinfection method of the present embodiment can be implemented by the user performing a disinfectant supply step of detecting that the finger is held in front of the disinfection device and supplying the disinfectant, a guiding step of visually and auditorily guiding the user so as to guide the rubbing-in of the disinfectant onto the finger, and an end notification step of notifying the user that the disinfection process has ended. Each of these steps can be implemented by executing the disinfection device according to the above-mentioned program.

[0022] 〔Function and effect〕 The guiding device and disinfection device of the present invention can be used as described above, whereby the disinfectant can be stably rubbed into all parts of the fingers of an individual in a short time regardless of the person, and disinfection can be performed. This is because, due to the visual and / or auditory guidance by the guiding device, after the disinfectant is supplied from the nozzle to the user's hand, the electronic metronome of the guiding device 20 visually and auditorily stimulates the user rhythmically by sound and / or light. As a result, the user moves the fingers rhythmically and can smoothly proceed with the rubbing-in operation (disinfection process). The use of such a guide device can encourage nurses and doctors, particularly in hospitals and other medical institutions, to disinfect their hands in a consistent, reliable manner with little individual variation, which is beneficial for improving compliance with hand disinfection and ensuring reliable disinfection.

[0023] <Second embodiment of guide device (disinfection device)> Next, a second embodiment of the guide device (corresponding to the second form of the disinfection device) will be described. The disinfection device used is the same except for the guide device, so it is given a reference number in the 100s, and the description is omitted except for the parts that are different from the first embodiment. Therefore, the description in the first embodiment above is applicable to the points that are not particularly described in detail. As shown in Fig. 3, the disinfection device 101 of this embodiment differs in that the guide device 120 is a small display 121 instead of a light emitting unit, and is equipped with a recording medium that stores data to be displayed on the display and a central processing unit (CPU) for displaying the data on the display (both not shown). The control program stored in the control device may be the same as that of the first embodiment, but the program for operating the CPU of this guide device 120 to display a predetermined image based on the above data is implemented in a recording medium in the guide device 120. On this display, images A to G shown in FIG. 4 are displayed in the order, and finally, the display indicates that the process has been completed. The images A to G are each in accordance with the method of rubbing the disinfectant on the hands and fingers described in the above-mentioned [Method of Use].

The disinfection device 201 is provided with a finger insertion space 230 capable of supplying a disinfectant to the user's finger. In the finger insertion space 230, the ultraviolet irradiation unit 240 and the disinfectant supply unit 210 operate, ultraviolet irradiation is performed from the ultraviolet irradiation unit 240, the disinfectant is supplied from the disinfectant supply unit 210, and it is possible to supply the disinfectant to the user's finger and then rub it in and perform ultraviolet irradiation. Furthermore, it includes a first sensor 207 that detects when the user approaches the disinfection device, a second sensor 208 that detects when the user inserts a finger into a predetermined position in the finger insertion space, and a control device (not shown) that receives the detection signals from the sensors 207 and 208 and sends instructions to the guide device 220 and the disinfectant supply unit 210. After receiving the detection signal from the first sensor 207, the control device issues an instruction to the guide device 220 to guide the user to insert a finger into a predetermined position in the finger insertion space 230. After receiving the detection signal from the second sensor 208, the control device issues an instruction to the disinfectant supply unit 210 to supply the disinfectant and an instruction to the guide device 220 to start guiding. The guide device 220 is configured to guide the insertion of the finger, the supply of the disinfectant, the subsequent rubbing operation guidance of the disinfectant on the finger, and the extraction of the finger from the finger insertion space. Further, in this embodiment, the control device is configured to issue an instruction to irradiate ultraviolet rays to the ultraviolet irradiation unit after receiving the detection signal from the second sensor 208. The guide device is configured to guide the insertion of the finger, the supply of the alcohol disinfectant and the start of ultraviolet irradiation, the subsequent rubbing operation guidance of the disinfectant on the finger, and the extraction of the finger from the finger insertion space. This will be described in more detail below.

[0025] 〔Overall Structure of the Disinfection Device〕 The disinfection device 201 of the present invention shown in FIGS. 5(a) and 5(b) is rectangular in shape, with a guide device 220 laid on the upper surface, and a disinfectant supply unit 210, an ultraviolet irradiation unit 240, and a control device (not shown) provided inside. Further, an opening 205 for the user to insert a hand is provided on the front facing the user, and a first sensor 207 is provided above the opening. A finger insertion space 230 is provided inside the opening, and a second sensor 208 for detecting the insertion of a finger is provided in the finger insertion space 230.

[0026] 〔Disinfectant Supply Unit〕 As shown in Fig. 5(b), the disinfectant supply unit 210 includes an electric disinfectant ejector 211 having a nozzle 211a and in which an electric ejection mechanism (not shown) is installed. This electric disinfectant ejector 211 is connected to sensors 207 and 208 via a control device, and is configured to eject a disinfectant upon receiving an instruction from the control device. The configuration of such an electric disinfectant ejector 211 can generally adopt a known one without particular limitation.

[0027] 〔Disinfection method and device using an alcohol disinfectant and ultraviolet light with a wavelength of 190 nm to 230 nm〕 In the finger disinfecting device of the present invention that uses an alcohol disinfectant and ultraviolet light with a wavelength of 190 nm to 230 nm in combination, it preferably includes a disinfectant supply unit that attaches an alcohol-based disinfectant to the object to be disinfected, an ultraviolet irradiation unit that irradiates the object to be disinfected with ultraviolet light having a wavelength of 190 nm to 230 nm, and an acoustic or visual / video guiding device that guides the rubbing of the disinfectant into the finger. Here, the supply / attachment of the disinfectant, the start and continuation of ultraviolet irradiation, and the activation of the device that guides the rubbing of the disinfectant are preferably controlled by a control circuit and a control mechanism in response to a detection signal of the insertion of a finger into the finger insertion space by a sensor. Hereinafter, an embodiment of a finger disinfecting device that uses a disinfectant and ultraviolet light with a wavelength of 190 nm to 230 nm in combination and has a rubbing-in guiding device for the disinfectant on the finger will be described with reference to the drawings. However, the finger disinfecting device with a rubbing-in guiding device for the disinfectant on the finger that uses the disinfectant and ultraviolet light in combination of the present invention is not limited to this example.

[0028] 〔Ultraviolet irradiation unit〕 The ultraviolet irradiation unit 240 is configured to be able to irradiate the inside of the finger insertion space 230. As shown in Fig. 5(b), two ultraviolet lamps 241, 243, 245, and 247 are arranged on the upper and lower surfaces of the finger insertion space. As these ultraviolet lamps, an ultraviolet lamp that emits ultraviolet light with a wavelength of 190 nm to 230 nm as the main wavelength light is preferable. For example, a product named "Care222 excimer lamp" manufactured byUSHIO INC. can be used. The average irradiation intensity of the ultraviolet light of the ultraviolet lamp used is 0.1 to 5 mW / cm 2, preferably 0.2 to 2 mW / cm 2 , and as the irradiation energy, it is 0.5 to 50 mJ / cm 2 , preferably 1 to 20 mJ / cm 2 It is preferably set as such.

[0029] 〔Finger insertion space〕 The finger insertion space 230 is a rectangular or trapezoidal space having a sufficient width for rubbing the finger inside, and the distance between its upper and lower surfaces is preferably 10 to 30 cm, more preferably around 20 to 25 cm, due to the necessity of rubbing an alcohol-based disinfectant into the finger while irradiating ultraviolet rays. If the distance between the upper and lower surfaces is too long, the intensity of ultraviolet rays on the finger surface will decrease and disinfection will be insufficient. If it is too short, it will hinder the rubbing operation of the finger. The upper and lower surfaces of the finger insertion space 230 of the ultraviolet rays are all sealed except for the nozzle 211a, and it is configured so that the discharged disinfectant does not directly adhere to the ultraviolet lamps 241, 243, 245, 247 and other wirings and does not adversely affect the electrical system. Specifically, the upper and lower surfaces of the finger insertion space 230 are all sealed so that an energization device (not shown) that supplies power to the ultraviolet lamps 241, 243, 245, 247, the disinfectant supply unit 210, and the ultraviolet irradiation unit 240 is not exposed on the finger insertion space 230 side. Also, at the installation location of the nozzle 211a, the periphery of the nozzle is sealed with a commonly used sealing material so that the discharged alcohol-based disinfectant does not leak out.

[0030] 〔Regarding finger disinfection by ultraviolet irradiation〕 If finger disinfection is performed by the combined use of ultraviolet rays of 190 nm to 230 nm and a disinfectant as in this embodiment, a sufficient disinfection effect can be obtained in a short time with a smaller amount of disinfectant used. If the amount of disinfectant used is small, there is an advantage that the hands of the subject are less chapped. The ultraviolet rays used in the present invention preferably have wavelengths in the range of 190 to 230 nm. Here, the "ultraviolet rays having wavelengths" refer to ultraviolet rays mainly composed of ultraviolet rays of the above wavelengths, and may include ultraviolet rays other than the ultraviolet rays of the above wavelengths. In that case, the content of ultraviolet rays having wavelengths of 230 nm or more is preferably 15% or less, preferably 5% or less, and more preferably 3% or less in terms of energy conversion in the whole ultraviolet rays. The wavelength distribution of the ultraviolet rays is not particularly limited as long as it has wavelengths in the range of 190 to 230 nm, and it may show a sharp peak with a half-value width of 2 nm at a specific wavelength, or may have a broad spectral distribution. As the lamp for irradiating ultraviolet rays of 190 nm to 230 nm, an excimer lamp, an LED (Light emitting diode), a fluorescent lamp, etc. can be used. When the emitted light contains components having wavelengths longer than 230 nm, it is preferable to suppress the emission of light having wavelengths longer than 230 nm by a band-pass filter or the like. Alternatively, it is preferable to use it within a range where the irradiation amount of the included long-wavelength light does not harm the human body. As the excimer lamp, an excimer lamp filled with KrCl of 221 to 223 (222) nm is preferably used. The ultraviolet rays using such an excimer lamp can be, for example, those described in Patent Documents 1, 2, 3 or 5, etc., but are not limited thereto. Also, an ultraviolet lamp combining a plasma light source, a phosphor, and a fluorescent glass can be used. The average irradiation intensity of the ultraviolet rays is 0.1 to 5 mW / cm 2 , preferably 0.2 to 2 mW / cm 2 The irradiation energy is 0.5 to 50 mJ / cm 2 Preferably 1 mJ / cm2 to 20 mJ / cm 2 It is preferable to set it as such.

[0031] 〔Combined treatment of ultraviolet irradiation and alcohol-based disinfectant〕 Regarding the method of disinfection by combining ultraviolet irradiation and treatment with an alcohol-based disinfectant, methods such as irradiating with ultraviolet rays after attaching the disinfectant to the fingers and rubbing it in, starting ultraviolet irradiation simultaneously with attaching the disinfectant to the fingers and irradiating with ultraviolet rays while rubbing in the disinfectant, irradiating with ultraviolet rays while rubbing in the disinfectant immediately after attaching the disinfectant to the fingers, and attaching the disinfectant after ultraviolet irradiation and rubbing in the disinfectant can be considered. However, a method of irradiating with ultraviolet rays while rubbing in the disinfectant simultaneously is preferred. Regarding the usage amount of the alcohol-based disinfectant and the irradiation energy of the ultraviolet rays, it is preferable to be within the aforementioned ranges.

[0032] 〔Guide device〕 The guide device of this embodiment is configured in the same manner as that of the first embodiment. However, it may also be configured to display an image in the same manner as the guide device of the second embodiment.

[0033] 〔Control device and control program〕 The control device is configured in the same manner as that of the first embodiment, and a control program for controlling the disinfection device of this embodiment is stored in its recording medium. By this control program, instructions are given to the disinfectant supply unit 210, the ultraviolet irradiation unit 240, and the guide device 220 to control the entire disinfection device. Regarding the control program, as shown in FIG. 6, the control program of this embodiment consists of a detection step S210, a disinfectant supply ultraviolet irradiation step S220, a guide step S230, and an end instruction S240. (Detection step S210) In this step, when receiving a signal from the first sensor 207, the presence of the user is grasped and it is determined that there is a "user". When the user inserts their hand into a predetermined position directly below the disinfectant supply nozzle 211a in the finger insertion space 230 and a signal from the second sensor 208 is received, it is determined that use has started and it is grasped that the user "uses". (Disinfectant supply ultraviolet irradiation step S220) This step is to give an instruction to the electric disinfectant dispenser 211 in the disinfectant supply unit 210 to discharge the disinfectant and an instruction to start ultraviolet irradiation to the ultraviolet irradiation unit 240. When it is determined as "to be used" in the detection step, an instruction to discharge the disinfectant and an instruction to start ultraviolet irradiation are given. It is preferable that the electric disinfectant dispenser 211 and the ultraviolet irradiation unit 240 are incorporated with controllable terminals such as known switch terminals so that they can execute the discharge of the disinfectant and the start of ultraviolet irradiation respectively upon receiving this instruction. Note that the start of ultraviolet irradiation may be set to start after the rubbing-in of the disinfectant onto the fingers is completed. (Guide step S230) This step is to give an instruction to the guide device to prompt the user to use it when it is determined that "there is a user". Further, when it is determined as "to be used" and upon receiving the completion of the supply of the disinfectant, this step is to give an instruction to start the guide and an instruction to end the guide when the guide for a predetermined time is completed. The completion of the supply of the disinfectant can be set by various methods, but in this embodiment, it is set to give an instruction to start the guide 1 second after the instruction to the electric disinfectant dispenser 211 in the disinfectant supply ultraviolet irradiation start step S220. And it is set to give an instruction to end the guide after a predetermined time has elapsed since the start of the guide for a predetermined time. At this time, it is also set to give an instruction to end the ultraviolet irradiation simultaneously. Note that when the start of ultraviolet irradiation is set to start after the rubbing-in of the disinfectant onto the fingers is completed, it is set to end the irradiation after irradiating for a predetermined time. Also, the guide device of the second embodiment may be incorporated to provide the user with a method of rubbing in the disinfectant. (End instruction S240) This step is to convey to the user the end of all disinfection processes. Since the end of the guide is instructed in the guide step, upon the arrival of the time to end after the start of the guide, an instruction is given to the above-mentioned guide device 220 to guide the user to the end of the disinfection process. Specifically, by making both the sound different from that during the guide and the light-emitting parts 221 and 223 emit light, etc., a visual and auditory display different from that during the guide is performed to notify the user of the end of the disinfection process.

[0034] [Other members] During ultraviolet irradiation, it is preferable to display that irradiation is in progress. Therefore, it is also possible to implement a lamp or the like in the guide device to notify the end of ultraviolet irradiation. In some cases, a shielding member can also be provided to prevent ultraviolet rays from entering the eyes of the disinfection operator or people in the vicinity of the disinfection device.

[0035] [Usage method (third embodiment of the disinfection method of the present invention using the disinfection device of the present invention)] The finger disinfection method of the present invention can be implemented by using the disinfection device of the present embodiment provided with the guide device of the present embodiment, while receiving ultraviolet irradiation, rubbing the disinfectant into the finger according to the guidance of the guide device, and disinfecting the finger. The disinfection method of the present invention can be implemented so that the rubbing of the disinfectant onto the entire surface of the finger is completed preferably within less than 15 seconds, more preferably within 10 seconds from the start of the disinfection treatment. The disinfection method of the present invention performs both ultraviolet irradiation with a wavelength of 190 nm to 230 nm and treatment with a disinfectant. Specifically, a disinfectant supply / ultraviolet irradiation step in which the user inserts a finger into the finger insertion space 230, the sensor 208 reacts, and the disinfectant is supplied from the nozzle 211a and at the same time ultraviolet irradiation is started, a guide step in which the user is visually and auditorily guided to guide the rubbing of the disinfectant onto the finger, and an end notification step in which the user is notified that the disinfection treatment has ended are performed. Each of these steps can be implemented by executing the disinfection device according to the above program. (Disinfectant supply / ultraviolet irradiation step) When the user inserts a finger from the opening 205 to a predetermined position directly below the disinfectant supply nozzle 211a in the finger insertion space 230, the sensor 208 reacts and the disinfectant is supplied from the nozzle 211a and at the same time ultraviolet irradiation is started. (Guide step) A step of driving the guide device so as to rub the disinfectant into the fingers in accordance with the rhythm of the guide device. At this time, ultraviolet irradiation is also performed. Since the disinfection device of the present embodiment is configured as described above, it is possible to simultaneously perform disinfection by ultraviolet irradiation, adhesion of the disinfectant, and rubbing-in without inhibiting the respective effects, and the disinfection time can be shortened. (Completion notification step) When the guiding for a predetermined time is completed, the user is notified of the end of the disinfection process.

[0036] (Function and effect) The guide device and the disinfection device of the present embodiment can be used as described above. Similar to the first embodiment, the disinfectant can be stably rubbed into the entire surface of the fingers for disinfection in a short time. In particular, according to the disinfection device and the disinfection method of the present embodiment, since the disinfectant and ultraviolet irradiation are used in combination, when evaluating the finger disinfection effect by a method conforming to ASTM E2755-15 "In vivo evaluation method of biocidal agents for hygienic (medical) hand hygiene (disinfection) of healthcare workers", it is possible to reduce the number of bacteria to 1 / 100 to 1 / 1000 or less before treatment with a smaller amount of disinfectant used and a shorter disinfection treatment (disinfection treatment of 15 seconds or less) than the conventional method, and also reduce skin roughness of the fingers. That is, when the disinfectant and ultraviolet rays are used in combination, there is an advantage of less hand roughness because a sufficient disinfection effect can be obtained even with a smaller amount of the disinfectant used compared to disinfection with the disinfectant alone. However, with the disinfection device of the present invention having the guide device of the present invention, the combined effect can be further improved, and disinfection can be performed more effectively and stably in a shorter time.

[0037] Note that the guide device and the disinfection device of the present invention are not limited to the above-described forms, and various modifications can be made without departing from the spirit of the present invention. For example, in the disinfection devices shown in FIGS. 1 and 5, it is not necessary to provide both a visual guide device and an auditory guide device, and either one may be sufficient.

Example

[0038] Hereinafter, the present invention will be described more specifically by way of Examples and Comparative Examples, but the present invention is not limited thereto in any way.

[0039] [Example 1] For 7 subjects, using the disinfection device shown in FIG. 5, in accordance with the "Determining the Bacteria-Eliminating Effectiveness of Healthcare Personnel Hand Rub Formulations Using Hands of Adults" (ASTM E2755-15) of the American Society for Testing and Materials (ASTM) as defined in the Tentative Final Monograph (TFM) of the Food and Drug Administration (FDA) of the United States, a disinfection test was conducted. The disinfection performance is indicated by LR (= Log10 Reduction, logarithmic reduction value of the number of bacteria). Here, the reduction value of the number of bacteria is calculated from the average value of the number of bacteria before disinfection and the average value of the number of bacteria after disinfection treatment using the following formula, and this is used as the disinfection performance LR. Note that LR is expressed with one digit after the decimal point (rounded down). LR (Log10 Redcution) = log (average number of bacteria before disinfection) - log (average number of bacteria after treatment). In this test, the evaluation was performed using the LR after one disinfection. The maximum and minimum values of LR for 7 subjects were excluded one by one, and the evaluation was performed using the average value of LR of the data for 5 subjects. As the alcohol-based disinfectant, about 1.5 ml of disinfection EtOH containing 0.2 w / v% each of chlorhexidine gluconate and diisobutyl adipate was used. The irradiation intensity of ultraviolet rays was 0.5 mw / cm as the average value of each part of the finger. 2 was set.

[0040] The test method is described below. 1) Finger contamination with test bacteria After washing and drying both hands with soap without a bactericide, Serratia bacteria ~1x10 100.2 mL of the test bacterial solution containing cfu / ml was inoculated onto both hands and dried while rubbing them together to spread it over the entire hands and fingers in about 30 seconds. 2) Measurement of the number of contaminating bacteria before the disinfection test Two sterilized polyethylene bags containing 75 mL of SCDLP were prepared in advance. Immediately after drying in 1), each hand was placed into the sterilized bag so that SCDLP covered the entire fingers. Then, referring to the glove juice method, two assistants massaged the entire fingers from above the bag to wash out the test bacteria. The operation of washing out the test bacteria was carried out in about 1 minute. The washing solution was diluted with physiological saline to prepare a 10-fold serial dilution series. 0.1 mL of each of the washing solution and the dilution was smeared on SCD medium and cultured at 25 ± 2°C for 44 hours. After culturing, only the test bacteria (Serratia) that formed red colonies were counted to determine the number of bacteria adhering to the fingers per right or left hand. 3) Control test (reference control) and sampling of the control test specimens 60 vol% isopropanol is used as the control test preparation. It was carried out within 10 seconds after completing the finger drying step in 1). 1.5 mL of 60% isopropanol was dropped as follows for disinfection. The procedure was carried out in about 40 seconds according to the following (1) to (3). (1) Drop 1.5 mL of 60% isopropanol onto the cupped palm (0.75 mL / hand). (2) Spread it over the entire fingers and nails of both hands within about 10 seconds while paying attention. (3) Repeat the following a) to f) (for a total of 5 seconds) and rub for 30 seconds (repeat 6 times). a) Cross the fingers of both hands and rub the palm vigorously 2 times (outer side of the left thumb, slightly less than 1 second). b) Rub the palm vigorously 2 times in the same way as a) (inner side of the left thumb, slightly less than 1 second). c) Rub the back of the left hand 2 times with the palm of the right hand (slightly less than 1 second). d) Rub the back of the right hand 2 times with the palm of the left hand (slightly less than 1 second). e) Gather the fingertips of the right hand and rub the nail tips together 2 times with the palm of the left hand (slightly less than 1 second). f) Curl the fingertips of the left hand and rub the fingernails together twice with the palm of the right hand (less than 1 second). The rubbing is performed in accordance with the guide signal (sound and blinking of the lamp, or the signal sound of the metronome) for the rubbing operation of the disinfection device. (4) Measurement of the number of bacteria after disinfection The test bacteria after disinfection were collected and the number of bacteria was measured in the same manner as in the above (2) "Measurement of the number of contaminating bacteria before the disinfection test".

[0041] 4) Disinfection with the disinfection device Similar to (3), after finger contamination, disinfection with the disinfection device was started within about 10 seconds. The disinfectant was applied for 1 second from the disinfectant supply unit, and then the rubbing operation of the disinfectant was performed for 10 seconds. The procedure was carried out according to the following (1) to (4). (1) Insert the palms of both hands into the opening 205 of the device in a cup shape. (2) The disinfectant is discharged for about 1 second. Receive it with both hands. (3) Immediately after the disinfectant adheres to the palms, in accordance with the signal of the guide device, the procedures a) to f) of (3) of the control test are repeated twice to perform the rubbing of the disinfectant for 10 seconds. At this time, ultraviolet irradiation was not performed. (4) Pull out both hands from the device after 10 seconds. 5) Measurement of the number of bacteria after disinfection The test bacteria after disinfection were collected and the number of bacteria was measured in the same manner as in the above (2) "Measurement of the number of contaminating bacteria before the disinfection test". 6) LR The LR calculated from the measured number of bacteria in (2) and (4) above was LR = 2.6, and the number of bacteria was 1 / 400 or less, indicating a high disinfection effect. The LR of the reference control was 2.6.

[0042] [Example 2] In the procedure (3) of "Disinfection with the disinfection device" in Example 1, disinfection with the disinfection device was performed in the same manner as in Example 1 except that ultraviolet irradiation was performed for 10 seconds simultaneously with the rubbing of the disinfectant, and the number of bacteria after disinfection was measured. The average irradiation energy of ultraviolet rays was 5 mJ / cm 2 as specified. The LR was 3.5, the number of bacteria was 1 / 3000 or less, and the disinfection effect was very high. The LR of the reference control was 2.8.

[0043] 〔Example 3〕 In Example 2, finger disinfection was performed in the same manner as in Example 2, except that the disinfection time, the rubbing time of the disinfectant, and the ultraviolet irradiation time were set to 8 seconds. Here, in the rubbing operation of the disinfectant, the procedures a) to f) were performed in the first 5 seconds, and then the procedures a) to d) were performed in 3 seconds, so that the total disinfection time was 8 seconds. The average ultraviolet irradiation energy was 4 mJ / cm 2 was set. The LR was 2.9. It can be seen that even in a short time of 8 seconds, according to the present invention, a sufficiently high finger disinfection effect can be easily obtained with a small amount of disinfectant used. The LR of the reference control was 2.7.

[0044] 〔Example 4〕 After the disinfectant was attached in the same manner as in Example 1, the rubbing operation was performed for 5 seconds, and then ultraviolet rays were immediately irradiated for 5 seconds. The procedure was performed according to the following (1) to (5). (1) Insert the palms of both hands in a cup shape through the opening 205 of the device. (2) The disinfectant is discharged for about 1 second. Receive it with both hands. (3) Immediately after the disinfectant adheres to the palm, according to the signal of the guide device, the disinfectant is rubbed in according to the procedures 3)-(3)a) to f) of Example 1 for 5 seconds. (4) After (3) is completed, fix the back of the hand diagonally upward. At this time, keep the fingers apart and open about 5 mm between the right thumb and the left thumb. (5) Irradiate with ultraviolet rays for 5 seconds. When the ultraviolet rays disappear after 5 seconds, pull both hands out of the device. The average ultraviolet irradiation energy was 2.5 mJ / cm 2 is. The LR was 2.5, the number of bacteria became 1 / 300 or less, and the disinfection effect was high. The LR of the reference control was 2.5.

[0045] 〔Comparative Example 1〕 In Example 4, finger disinfection was performed in the same manner as in Example 4, except that the amount of the disinfectant was set to approximately 3 ml, which was twice the amount, and the rubbing-in of the disinfectant for 5 seconds was performed without the guide of the guide device. The result was LR = 2.4. Despite doubling the amount of the disinfectant, the LR was lower than that in Example 4, and the disinfectant did not dry even after 15 seconds had passed since the attachment of the disinfectant. The LR of the reference control was 2.5. From the above, it can be seen that by performing disinfection using the disinfection device equipped with the guide device of the present invention, finger disinfection can be performed with a small amount of disinfectant in a short time.
