Abstract

PROBLEM TO BE SOLVED: To provide a sterilizer capable of properly sterilizing the footwear of a hospitalized patient, without creation of extra work for the patient.SOLUTION: The sterilizer includes a footwear detector 1 which detects footwear placed on a predetermined position for removal of footwear adjacent to a bed, and a bed sensor 2 which detects the presence of a person on the bed. When the bed sensor 2 detects a person on the bed within a predetermined time after detection of the placed footwear with the footwear detector 1, a controller 5 activates a UV irradiation unit 3, so that the predetermined position for removal of footwear is exposed to UV rays with the UV irradiation unit 3. Only when not only the footwear is placed on the predetermined position, but also the patient rides on the bed after removal of the footwear on the predetermined position, the footwear is exposed to UV rays. Consequently the footwear is sterilized when the patient only rides on a bed after removal of the footwear on the predetermined position. Accordingly the footwear is properly sterilized without creation of extra work for the patient.

Description

  The present invention relates to a footwear sterilizing apparatus for sterilizing footwear, and in particular, for sterilizing footwear worn by a patient, which is used in the vicinity of a bed in a hospital.

  Generally, patients who are admitted to a hospital wear footwear such as slippers when moving within the hospital and take off their footwear when they are in bed. Therefore, various bacteria may adhere to footwear worn by the patient as the patient moves in the hospital.

  As a technology to sterilize bacteria attached to footwear, when the used slippers are put in the storage box and the door of the storage box is closed, the UV germicidal lamp and ozone generator are automatically operated. The thing which sterilizes a slipper is known (for example, refer patent document 1).

  However, when the sterilization apparatus described in Patent Document 1 described above is installed in the vicinity of each bed, each patient has to store his / her footwear in a storage box and must close the open / close door. There was a problem of letting it go.

  The present invention has been made to solve such a problem, and an object thereof is to appropriately sterilize footwear of a hospitalized patient without causing the patient to take extra time. To do.

  In order to solve the above-described problems, in the present invention, a footwear detection unit that detects that footwear is placed at a predetermined position where the footwear in the vicinity of the bed is removed, and a bed sensor that detects that a person is on the bed When a person on the bed is detected by the bed sensor within a predetermined time after the footwear detecting unit detects that the footwear is placed, UV light is applied to a predetermined position where the footwear is removed. I try to irradiate.

  According to the present invention configured as described above, not only the footwear is placed in a predetermined position, but also after the footwear is placed in the predetermined position, the ultraviolet ray is emitted only when the patient wearing the footwear gets on the bed. Since the footwear is irradiated, the patient can sterilize the footwear by simply taking off the footwear in a predetermined position and getting on the bed, and can properly sterilize the footwear without causing the patient extra effort. .

It is a block diagram which shows the structural example of the sterilizer for footwear by this embodiment. It is a figure which shows the example of an external appearance of the sterilizer for footwear by this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a footwear sterilizer according to the present embodiment. Moreover, FIG. 2 is a figure which shows the example of an external appearance of the sterilizer for footwear by this embodiment. As shown in FIG. 1, the sterilization apparatus for footwear of this embodiment includes a footwear detection unit 1, a bed sensor 2, an ultraviolet irradiation unit 3, a timer 4, and a control unit 5.

  The footwear detection unit 1 is configured by a mat sensor or the like, and detects that the footwear is placed at a predetermined position on the floor surface near the bed where the footwear worn by the patient is removed. Here, as shown in FIG. 2, when the footwear is placed on the mat sensor constituting the footwear detecting section 1, the footwear detecting section 1 generates a footwear detecting signal.

  The bed sensor 2 is composed of a mat sensor or the like, and detects that there is a patient on the bed. Here, as shown in FIG. 2, the mat sensor constituting the bed sensor 2 is installed on the bed. Further, when a patient gets on the bed, the bed sensor 2 generates a patient detection signal.

  As shown in FIG. 2, the ultraviolet irradiation unit 3 is installed on the side surface of the bed or the like, and irradiates ultraviolet rays to a predetermined position where the above-described footwear worn by the patient is removed. Here, the time during which the ultraviolet irradiation unit 3 irradiates ultraviolet rays is determined by the distance between the ultraviolet irradiation unit 3 and a predetermined position.

  The timer 4 is for measuring time, and outputs the measured time information. The control unit 5 is for controlling each component of the footwear sterilizer as described later, and is configured by a CPU (Central Processing Unit) or the like.

  That is, when the footwear detecting unit 1 detects that the footwear is placed, the control unit 5 activates the timer 4 so that the person on the bed has reached the predetermined time until the time measured by the timer 4 reaches a predetermined time. When the presence of the bed sensor 2 is detected, the control unit 5 operates the ultraviolet irradiation unit 3. Here, the above-mentioned predetermined time corresponds to the time from when the patient takes off his / her footwear until he gets on the bed, and is set to 1 minute, for example.

  Next, the operation of the footwear sterilizer configured as described above will be described. When a patient who has moved in the hospital takes off his / her footwear at a predetermined position, the footwear detecting unit 1 detects the footwear and outputs a footwear detection signal to the control unit 5. Further, the control unit 5 operates the timer 4.

  When the patient who removes his / her footwear gets on the bed before the time information measured by the timer 4 reaches the predetermined time, the bed sensor 2 detects the patient and outputs a patient detection signal to the control unit 5. Then, the control part 5 operates the ultraviolet irradiation part 3, and the ultraviolet irradiation part 3 irradiates the footwear with ultraviolet rays for a certain period of time.

  On the other hand, when the bed sensor 2 does not detect the patient on the bed and the patient passes a predetermined position, the footwear detection unit 1 detects the footwear and outputs the footwear detection signal, but the timer 4 measures. Since the bed sensor 2 does not detect the patient on the bed even if the time information is a predetermined time, the control unit 5 does not operate the ultraviolet irradiation unit 3.

  In addition, when the bed sensor 2 detects a patient on the bed and the patient passes a predetermined position, the footwear detection unit 1 detects the footwear and outputs a footwear detection signal. However, since the patient on the bed is detected, the control unit 5 does not operate the ultraviolet irradiation unit 3.

  As described above in detail, in the footwear sterilizing apparatus according to the present embodiment, there is a footwear detection unit 1 that detects that footwear is placed at a predetermined position where the footwear in the vicinity of the bed is removed, and there is a person on the bed. The bed sensor 2 for detecting the footwear, and when the person on the bed is detected by the bed sensor 2 within a predetermined time after the footwear detector 1 detects that the footwear is placed, the controller 5 Operates the ultraviolet irradiation unit 3, and the ultraviolet irradiation unit 3 irradiates ultraviolet rays to a predetermined position where the footwear is taken off.

  This not only puts the footwear in place, but after placing the footwear in place, the patient is exposed to ultraviolet light only when the patient wearing the footwear gets on the bed. The footwear is sterilized only by taking off the footwear at a predetermined position and getting on the bed, and the footwear can be sterilized appropriately without causing the patient to take extra time.

  In the above-described embodiment, the mat sensor is used as the footwear detection unit 1 and the bed sensor 2, but the present invention is not limited to this. For example, a sensor such as an infrared sensor or an ultrasonic sensor may be used.

  Moreover, in embodiment mentioned above, in order to sterilize footwear, it is made to irradiate an ultraviolet-ray in the ultraviolet irradiation part 3, However, It is not limited to this. For example, an ozone generator may be used. That is, any means for sterilizing a predetermined position may be used.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
