Description

[Detailed description of the invention] This invention can economically and effectively sterilize medical-related rooms and equipment, such as operating rooms, surgical equipment rooms, hospital rooms, consulting rooms, and outpatient waiting rooms, and has a simple configuration. The purpose is to provide a germicidal lamp device that is easy to handle.A cylindrical reflector is provided between a movable base and a head member of the base that has a reflector on the top surface. Germicidal lamps are installed on the reflector of the component and inside and outside the cylindrical reflector, facing these reflectors, and dust removal filters are installed at least on the air introduction side of both openings of the cylindrical reflector. ,
A ventilated harmful ray leak prevention body is attached to the upper opening, and an air circulation fan is provided at either of the openings of the cylindrical reflecting plate.

Recently, operating rooms and surgical equipment rooms in hospitals and clinics are required to be particularly clean areas, especially equipment-related items mainly for protecting surgical wounds, and dust removal and sterilization of the air environment. There is a growing demand for higher levels of performance.

Conventionally, there are bioclean air conditioners, sterilizing air conditioners, and indoor germicidal lights that meet these demands.

However, bioclean air conditioners are large-scale and expensive to prepare the air environment in general medical rooms, and are not suitable for use in places other than those that require special indoor environments, such as sterile operating rooms.

Furthermore, most sterilizing air conditioners are of a circulation air conditioning type in which the air in many rooms is centrally controlled by a large-scale device, which is not suitable for simply sterilizing a single room.

A common way to sterilize a room is to use an indoor sterilizing lamp, which consists of two to four sterilizing discharge tubes installed above the indoor wall, and the lower part covered with a louver to prevent direct light from entering the room. Most of these are wall-mounted types that sterilize the indoor air by directly irradiating air from the ceiling and the upper part of the room.

However, since this method is fixed at the top of the wall, it only sterilizes the air in the upper layer of the room and the ceiling, but cannot sterilize the air in the lower layer of the room, appliances, and other items installed in the room. Looking at it, I can't expect much of a bactericidal effect.

In addition, as a mobile sterilizer, for example, as described in Japanese Utility Model Publication No. 10860/1986, a large number of sheets are installed in the ventilation passage inside the housing, which has an air inlet at the bottom and an air outlet at the top. An electric dust generator is provided in which discharge electrode plates and dust collecting electrode plates are arranged in parallel with the ventilation direction alternately and with a gap between them, and several ultraviolet lamps are arranged in parallel on the upper surface of the electric dust generator. There is an air sterilizing and purifying device that includes a series of exhaust devices.

Even though this method can sterilize the indoor air, the dust collection effect of the electric precipitator is significantly reduced depending on the wind speed of the exhaust fan, so sterilization must be slow.
Moreover, since the dust collecting electrode plate collects dust and other contaminants by suction and adhering to them, there is a problem that even though the dust has been sterilized, the dust and other contaminants are circulated back into the room by the exhaust fan. At the same time, as with the indoor sterilizing lamp, it is not possible to sterilize instruments and other indoor objects.

Furthermore, due to its structure, there was a risk that harmful light from the germicidal lamp would leak out of the housing.

As described above, conventional indoor sterilizers have their advantages and disadvantages, and none of them has been able to easily sterilize indoor air, surgical instruments, and the like.

This invention was completed as a result of intensive experimental research to solve these problems.

An embodiment of the germicidal lamp device according to the present invention will be described with reference to the attached drawings.

A net-like ventilation 1 is provided on the lower circumferential side, and casters 3 are attached to the lower surface periphery of the base 2, which has an opening at the center of the lower part, making the base 2 movable. .

At the center of the base 2, both upper and lower ends of a cylindrical reflecting plate 4 made of a metal plate with mirror-finished inner and outer surfaces are fixed by the base 2 and the head member 5.

The base 2 and the head member 5 are composed of three support pipes 6 arranged equiangularly inside the cylindrical reflector 4.
As a result, the discharge tubes are connected and fixed by six discharge tube protection rods 7 arranged equiangularly on the outside of the cylindrical reflection plate 4.

The head member 5 has an opening at the center, and a flat reflecting plate 17 made of a metal plate whose upper surface is mirror-finished, extending from the opening to the periphery of the head member 5.
However, it is installed with a gentle slope that is higher at the center and lower at the periphery.

There are sterilizing lights: one at the center of the cylindrical reflector 4, three at equal angles on the outside of the cylindrical reflector 4, and four in a rectangular shape above the flat reflector 17 on the top of the head member 5. Ultraviolet discharge tubes 8, 8a, and 8b are arranged facing the respective reflecting plates 4 and 17.

A motor fan 9 is installed below the cylindrical reflector 4 at the center of the base, and a dust removal filter 10 is detachably attached to the lower side of the cylindrical reflector 4 so that the inside of the cylindrical reflector 4 is sealed.

A back cover 11 is removably attached to the opening on the lower surface of the base 2 to facilitate maintenance after installation, such as cleaning and replacing the dust removal filter 10 and repairing the motor/fan 9 when it breaks down.

A fin 12 is attached to the opening at the center of the head member 5, and the fin 12 is made up of a large number of ultraviolet absorbing materials or thin plates treated with ultraviolet absorbing treatment arranged side by side.
As a result, the ultraviolet discharge tube 8a inside the cylindrical reflector 4
When the lamp is turned on, the harmful rays are reflected on the cylindrical reflector plate 4.
Direct leakage from the inside to the outside is prevented, and the air raised inside the cylindrical reflecting plate 4 by the motor fan 9 is rectified so as to be discharged at a desired angle.

Inside the head member 5, an operating section 13a such as a power switch, a changeover switch, two timer setting knobs (none of which are shown) is provided on the side, and each discharge tube 8, 8a, 8b is turned on and off. An electrical control member 13 for starting and stopping the motor/fan 9 is installed, and electrical components 14 such as a ballast are housed within the base 2.

In the figure, 15 is a power cable, 16 is a ventilation hole, and 18
is the discharge tube protection rod.

Next, an example of how the device of this embodiment is used will be explained along with its operation.

When lighting all the discharge tubes 8, 8a, and 8b at the same time: Move and install the sterilizing lamp device at a desired position in the room to be sterilized, and connect the power cable 15 to an outlet in the room.

Set the changeover switch in the operation section 13a to the all-lights-on side, turn one timer setting knob to light the discharge tubes 8, 8a, 8b, and set the time to start the motor fan 9, for example after 5 minutes. Turn the other timer setting knob to turn off the discharge tubes 8, 8a, and 8b, set the time to stop the motor fan 9, for example, 1 hour after lighting and starting, and turn on the power switch. The operator exits the room. After 5 minutes, all the discharge tubes 8, 8a, 8b are turned on by one of the timers, and the motor fan 9 is started.

By the motor fan 9, as shown in the third diagram,
Indoor air flows through ventilation holes 1 to 16.
After being removed by a dust removal filter 10, it is sterilized by a discharge tube 8a in a cylindrical reflection plate 4, rectified by a fin 12, and returned to the room.

In this way, the indoor air is dedusted and sterilized by forced circulation, while the discharge tubes 8 installed outside the cylindrical reflector 4 and the discharge tubes 8b installed above the head member 5 It is further sterilized by

In addition, installations, instruments, etc. installed and stored indoors are also sterilized by the sterilizing rays of these discharge tubes 8, 8b.

When one hour has passed in this state, all the discharge tubes 8, 8a, 8b are turned off by the other timer, and the motor fan 9 is also stopped.

After that, turn off the power switch if it is not necessary.
Then, disconnect the power cable 15 from the outlet,
Move this device to an appropriate location.

When lighting only the discharge tube 8a inside the cylindrical reflector 4: Move and install the present germicidal lamp device to a desired position in the room to be sterilized, and connect the power cable 15 to an outlet or the like in the room.

Turn the changeover switch in the operation section 13a to the internal discharge tube lighting side, set one timer to 0 and the other timer to 1 hour, and turn on the power switch.

At the same time as the power switch is turned on, the discharge tube 8a inside the cylindrical reflector 4 lights up and the motor fan 9 starts.

By the motor fan 9, as shown in the fourth diagram,
Indoor air flows through ventilation holes 1 to 16.
After being removed by a dust removal filter 10, it is sterilized by a discharge tube 8a in a cylindrical reflection plate 4, rectified by a fin 12, and returned to the room.

After one hour has passed in this state, the discharge tube 8a is turned off by the other timer, and the motor fan 9
will also be suspended.

Thereafter, turn off the power switch, disconnect the power cable 15 from the outlet, and move the device to an appropriate location.

In any of the above cases, it is a matter of course that the fins 12 prevent harmful light rays from the internal discharge tube 8a from leaking into the room.

In addition, after all the discharge tubes 8, 8a, and 8b are lit and used at the same time, only the internal discharge tube 8a should be lit again as necessary to continue removing dust from the indoor air and sterilizing the indoor air. You can also do it.

In this embodiment, the configuration and use are shown as described above, but the cylindrical reflector is not limited to a cylindrical shape as long as it has a cylindrical shape, and for example, a cylindrical shape, a rectangular shape, a dogleg shape in cross section, a reverse dogleg shape, etc. , trapezoid, inverted trapezoid, or any other suitable shape depending on the desired reflection angle, and the design may be changed as appropriate within the scope of the present invention, such as the number of germicidal lamps and the installation position of the air circulation fan. Of course it can be done.

Since the germicidal lamp device according to the present invention has the above-mentioned configuration, it can easily remove dust from indoor air in each room with a device that is simpler and cheaper than conventional devices.
In addition, it is possible to uniformly and quickly sterilize indoor ceilings, walls, floors, installed objects, surgical instruments, etc., and since a sterilization lamp is installed on the top of the head member, ceilings that are difficult to clean can be sterilized evenly and quickly. Not only can it directly sterilize devices suspended from surfaces or ceilings, or even minute dust attached to them, but it is also movable, which particularly increases the degree of sterilization. You can easily move it to the desired location.

In addition, with this device, indoor air is forcibly circulated inside the cylindrical reflector by an air circulation fan, and as it passes through the cylindrical reflector, it is removed from dust and sterilized by direct light and reflected light from the germicidal lamp. Because of this, the indoor air that has been sterilized by the sterilizing lamp outside the cylindrical reflector is sterilized again by the sterilizing lamp inside the cylindrical reflector, resulting in a significant sterilizing effect.

Furthermore, in the case where the sterilizing lamp inside the cylindrical reflector and all the sterilizing lamps are turned on at the same time or separately, for example, at night, when no one is in or out of the room, All germicidal lights are turned on at the same time to remove dust from the indoor air and sterilize everything in the room, making sure that there are no people in the room, such as the operating room during surgery, the surgical equipment room, hospital rooms, consultation rooms, and outpatient waiting rooms. When the room is empty, only the internal germicidal lamp is turned on, and the harmful rays of the germicidal lamp are removed from the indoor air and sterilized without leaking from inside the cylindrical reflector to the outside. It is safe and convenient to use because the device can be used depending on the situation.
