Abstract

PURPOSE:To effectively sterilize bacteria in the treatment room and/or corridor of a hospital and solve problems such as nosocomial infection. CONSTITUTION:A sterilizing lamp 2 suspended from a ceiling 1 is generally formed of a capillary, and horizontally arranged. A light shielding plate 3 is rotatably provided around the sterilizing lamp 2, and when the light shielding plate 3 is in the state shown in a drawing (a) to the sterilizing lamp 2, ascending bacteria adhering to the ceiling can be effectively sterilized without exposing persons situated in a treatment room or a corridor with the light from the sterilizing lamp 2. On the other hand, in the night where no person is present in a consultation room or the corridor, the relation between the sterilizing lamp 2 and the light shielding plate 3 is laid in the state shown by a drawing (b), and the light emitted from the sterilizing lamp 2 is radiated downward to sterilize descending bacteria adhering to the floor.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sterilization method for sterilizing bacteria in a treatment room and / or corridor of a hospital, particularly a dental clinic.

[0002]

2. Description of the Related Art In the treatment room of a hospital, many outpatients come and go,
If care is not taken to effectively sterilize and disinfect these,
On the floor and on the surface of instruments and equipment or in the air,
A large number of microorganisms may remain, and the treatment room may become a place for transmitting pathogenic microorganisms from patient to patient, patient to operator, or operator to patient. Moreover, in recent years, so-called opportunistic infections caused by staphylococci on the skin or gram-negative bacilli, which have been widely distributed in nature and were originally considered to be pathogenic, attracted the attention of medical personnel, and caused nosocomial infection as a problem. Has been taken up.

[0003]

[Purpose] The present invention has been made in view of the above circumstances, and in particular, an object thereof is to effectively sterilize bacteria in a treatment room and / or corridor of a hospital to solve problems such as nosocomial infections. It was made as.

[0004]

In order to achieve the above object, the present invention provides a sterilizing lamp which is hung from a ceiling and is disposed horizontally, a light-shielding plate disposed on one side of the sterilizing lamp, and the light-shielding plate. A driving mechanism for driving the driving mechanism, and when the light emitted from the germicidal lamp is driven, the ceiling is irradiated when there is light, and the floor surface is irradiated when there is light. It is characterized by. Hereinafter, it demonstrates based on the Example of this invention.

FIG. 1 is a block diagram for explaining an embodiment of a sterilization method according to the present invention. In the figure, 1 is a ceiling of a treatment room or corridor of a hospital to which the present invention is applied, 2 is the ceiling 1 The sterilizing lamp 2 hangs from the sterilizing lamp 2. The sterilizing lamp 2 is usually made of a thin tube and is actually arranged horizontally as shown in the drawing. Reference numeral 3 denotes a shading plate rotatably provided around the germicidal lamp 2, and when the shading plate 3 is in the state shown in FIG. The light emitted toward the floor is blocked by the light blocking plate 3 and does not reach the floor surface. In other words, during the daytime medical care period, the relationship between the germicidal lamp 2 and the shading plate 3 is set to the state shown in FIG. (A) so that the person who is in the treatment room or the corridor can see the light from the germicidal lamp 2. It is possible to effectively sterilize the ascending bacteria adhering to the ceiling or the like without hitting.

On the other hand, the relationship between the germicidal lamp 2 and the light shielding plate 3 is changed at night, for example, at night when there is no person in the medical office or corridor.
In the state shown in the diagram (b), the light emitted from the germicidal lamp 2 is irradiated downward, and the descending bacteria adhering to the floor or the like can be killed. Although the light-shielding plate 3 is shown on the upper side of the germicidal lamp 2 in FIG.
The light need not necessarily be on the upper side, and the point is that the light from the germicidal lamp 2 may be irradiated on the lower side, and may be irradiated on the upper side at the same time.

Although the basic concept of the present invention has been described above, there are various methods for carrying out the present invention as described below, and all of them are one embodiment of the present invention. Not too much. In the present invention, as described above,
It is necessary to change the relative position of the germicidal lamp 2 and the light shielding plate 3,
This is performed by (1) the operation cord wire hung from the support 4 supporting the germicidal lamp 2 and the light shielding plate 3,
(2) A method in which a receiving device including a microcomputer or the like is attached to the side of the support 4 and the remote control operation is performed, (3) electrical wiring is performed in advance, and a wall switch or the like is turned on / off to operate There is. In that case, (1) the light-shielding plate 3 is made rotatable, and the light-shielding plate 3 is rotated around the germicidal lamp 2 to the state shown in (a) or the state shown in (b). (2) The shading plate 3 is made movable in the axial direction of the sterilizing lamp 2, and when irradiating the floor surface, the shading plate 3 is moved in the horizontal direction so that the light from the sterilizing lamp 2 is also moved downward. Various methods are conceivable such as irradiation. Further, with respect to the lighting time of the sterilization lamp 2 and the like, by providing a timer or the like, it is possible to turn on the lighting only for any desired time. For example, the floor surface cannot be irradiated because there are people during the daytime working hours (at this time, only the ceiling is irradiated as shown in Fig. (A)), and inevitably, Irradiation is performed during the nighttime when there are no people. In that case, the person who leaves the room last leaves the room with the relationship between the germicidal lamp 2 and the light shielding plate 3 shown in FIG. However, in such a case, it is convenient to automatically turn off the light after turning it on for a predetermined time by a timer. If the surface of the light shielding plate 3 is formed as a reflecting surface, the light from the germicidal lamp 2 can be used more effectively.

FIG. 2 is a view for explaining another embodiment of the present invention, in which 10 is the ceiling of the treatment room and 11 is the ceiling 1.
An intake pipe 12 hung from 0, an intake port 12 provided at the tip of the intake pipe 11, and the intake pipe 11 has an intake port 12
Is drawn near the patient's mouth, and the contaminated gas released from the patient's mouth and bacteria, dust, etc. floating near the patient's mouth are sucked and discharged. Is also provided with a germicidal lamp so that the contaminated air sucked from the intake port 12 is sterilized. 1
3 is a germicidal lamp attached to the member 15 to which the intake pipe 11 is attached, 14 is a light-shielding plate of the germicidal lamp 13, and the germicidal lamp 13
Is, for example, the light shielding plate 14 is rotated by the operation cord 16 so that the light emitted from the sterilization lamp 13 is radiated toward the ceiling in the daytime to sterilize the rising bacteria, so that the person in the treatment room at night or the like If not, the floor is irradiated to sterilize the descending bacteria.

[0009]

[Effect] As is clear from the above description, according to the present invention, sterilization in a clinic and / or corridor of a hospital can be effectively performed without causing any harm to humans, and there is a problem of nosocomial infection. Can be solved.
