In particular, the present invention relates to an apparatus for displaying a disinfection rate using disinfecting means installed at the entrance of a hospital room.

  In recent years, illness and death of hospitalized patients due to nosocomial infections have become a problem. It is known that the infection of pathogens from patient to patient through medical personnel such as doctors and nurses is a major cause of this nosocomial infection. Disinfection is the most important prevention method for nosocomial infections. For this reason, a disinfectant is installed at the entrance / exit of the hospital room, and hand sterilization is required when the patient room is entered and exited. The disinfectant rubs a finger with a solution of alcohol or the like, thereby killing pathogenic bacteria and disinfecting the finger.

  In this way, even though it is well known that hand sterilization is important in preventing hospital infections, it is cumbersome to perform hand sterilization when entering and leaving a hospital room, and busy medical personnel disinfect hands. I often neglect.

  An object of the present invention is to improve the sterilization rate of fingers of medical personnel entering and leaving each room. The present inventor thought that displaying the disinfection rate of the hand of a medical worker to each hospital room near the entrance of the hospital room would alert the medical worker and improve the disinfection rate of the finger. It is also conceivable that the disinfection rate of the fingers is improved by displaying the data for each room and stimulating the competitive consciousness among the persons in charge of each room. Furthermore, by collecting hand disinfection rate data, it is easy to take measures to improve the hand disinfection rate. Therefore, the present invention provides a device for displaying the disinfection rate of fingers that can be installed near the disinfectant placed near the entrance of each hospital room.

  According to one aspect of the present invention, in a sterilization rate display device including a passage detection device, a sterilization detection device, and a display device, the passage detection device transmits a signal to the display device when the mobile object passes through the hand hygiene area. When the disinfection detection device is attached to the disinfection liquid discharge means and the disinfection liquid discharge means is actuated, a signal is transmitted to the display device. The number of passes of the moving body is received and the number of passes of the moving object is received, the number of times of disinfection is received and the number of disinfections is stored, and the ratio of the number of passes of disinfection to the number of passes is calculated. The disinfection rate display device has a calculating means and a display. This device can be installed near the entrance of each hospital room and anyone can see the hand disinfection rate. Moreover, since this apparatus is a small and simple apparatus, it can be installed in many hospital rooms in a hospital.

  The indicator displays, for example, the number of passes, the number of sterilizations, and the sterilization rate. The number of passages is the total number of times that the mobile body passes through the hand hygiene area in a predetermined period, and the number of disinfections is the number of times that the disinfecting liquid discharging means containing the disinfecting liquid is operated within the period, that is, disinfection was performed. Is the number of times. The disinfection rate is a value obtained by dividing the number of disinfections by the number of passages, and is preferably expressed as a percentage. Here, the moving body is preferably a person who moves in the hand hygiene area.

The hand hygiene area is an area where a person who passes through the area or a part of the person who passes through the area needs to disinfect his / her fingers. The hand hygiene area is preferably an entrance to a hospital room.
In order to make the device small and simple, the passage detection device is preferably a human body detection sensor using an infrared sensor, and the disinfection detection device preferably also uses an infrared sensor, but other sensors and devices Can also be used.

  Transmission from the passage detection device and the disinfection detection device to the display device can be performed by any method. However, for downsizing and simplification of the device, the passage detection device and the display device, and the disinfection detection device and the display device are respectively connected by electric wires, and transmission from the passage detection device and the disinfection detection device to the display device is possible.

  It is preferable that the display device further has a display switch, and the display device is operated for a predetermined time when the display switch is turned on. The measurement of the disinfection rate is performed over several days to several months. However, when this apparatus is operated with a dry battery, it is considered that the battery is consumed and needs to be replaced. According to this configuration, information can be displayed only when necessary, so that battery consumption can be suppressed. The time for displaying information after turning on the display switch is preferably 3 to 30 seconds, but may be other time.

  According to another aspect of the present invention, a step of accumulating signals from an infrared sensor that detects a moving body that passes through an entrance of a hospital room and storing the number of passages, and an infrared sensor attached to the disinfectant discharging means Storing the number of sterilization times, calculating the sterilization rate by dividing the number of sterilization times by the number of passages, and displaying the sterilization rate. A method of displaying the disinfection rate is provided.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an embodiment of a disinfection rate display device of the present invention. The disinfection rate display device 1 relates to a device that displays a ratio of performing hand disinfection of medical personnel such as doctors and nurses entering and leaving a hospital room. This device includes a display device 6, and the display device 6 is connected to the passage detection device 2 and the sterilization detection device 4 by electric wires 12 and 13 and receives signals from the passage detection device 2 and the sterilization detection device 4. It is supposed to do.

  The passage detection device 2 uses a human body detection sensor using an infrared sensor. This sensor collects weak infrared rays emitted by the human body, and transmits the output to the display device 6 through the electric wires 13 when a person crosses the sensor field of view with a dual element type infrared sensor and amplifier. Yes. A pyroelectric sensor manufactured by Nippon Ceramic Co., Ltd. was used as the infrared sensor.

The sterilization detection device 4 is an infrared sensor and is attached to a sterilization liquid bottle (disinfection liquid discharge means) 20 to detect the number of times of use. In FIG. 1, the disinfectant liquid bottle 20 is composed of a hand pump 26 and a container 22, and when a head 28 of the hand pump 26 is pushed down with a palm, a certain amount is discharged from the tip of a nozzle 30 attached to the head 28. Disinfectant solution is discharged. When the palm is removed from the head 28 of the hand pump 26, the head 28 is raised by elastic means and returned to its original position. The user pushes down the head 28 with one hand, receives the disinfectant discharged from the tip of the nozzle 30 with the other hand, and disinfects the fingers by rubbing the disinfectant with both hands.
The means for depressing the hand pump of the disinfectant bottle may be used by attaching an instrument or device in addition to using a palm. For example, a non-contact type automatic depressing device with an infrared sensor may be used. In this device, when both hands or one hand is inserted under the nozzle, the infrared sensor detects the presence of the hand and operates the arm to automatically push down the head of the pump. Even when the automatic depressing device is used, the disinfection detecting device 4 can be attached in the same manner as described below. The disinfection rate display device according to the present invention can be applied regardless of means for depressing the hand pump to discharge the disinfectant.
