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 sterilizing lamp device that is easy to handle.A cylindrical reflector is provided on a movable base for ventilation, and a sterilizer lamp is mounted on the outside of the cylindrical reflector, facing the cylindrical reflector. A dust removal filter is attached to at least one of both openings of the cylindrical reflecting plate, and a ventilable harmful ray leak prevention body is attached to at least the other, and either of the openings of the cylindrical reflecting plate is attached. It is characterized by being equipped with an air circulation fan.

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 lamps 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 parallel to the energizing direction with a gap between them alternately, 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.

Although 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.

A base 2 and a head member 5 having an opening in the center
This means that three support pipes 6 are arranged equiangularly on the inside of the cylindrical reflector 4, and six discharge tube protection rods 7 are equiangularly arranged on the outside of the cylindrical reflector 4. Connected and fixed.

Ultraviolet discharge tubes 8a and 8, which are germicidal lamps, are disposed, one in the center of the cylindrical reflector 4 and three at equal angles on the outside of the cylindrical reflector 4, facing the cylindrical reflector 4, respectively. be done.

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, etc. (none of which are shown) is provided on the side. - An electrical control member 13 for starting and stopping the fan 9, etc. is installed, and electrical components 14 such as a ballast are housed in the base 2.

In the figure, 15 is a power cable, and 16 is a ventilation hole.

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

When lighting both the inner and outer discharge tubes 8a, 8: 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 in the room.

Turn the changeover switch in the operation section 13a to the all-lights-on side, turn one timer setting knob to light the discharge tubes 8a, 8, and set the time to start the motor fan 9, for example, after 5 minutes. , the time to turn the other timer setting knob to turn off the discharge tubes 8a, 8 and stop the motor fan 9;
For example, the setting is set for one hour after the lights are turned on and started, the power switch is turned on, and the operator leaves the room.

After 5 minutes, one timer turns on all the discharge tubes 8a,
8 lights up and the motor fan 9 starts.

As shown in the second diagram, the motor fan 9 removes dust from the air in the room through the ventilation hole 16 through the dust filter 10, and then sterilizes the air through the discharge tube 8a inside the cylindrical reflector plate 4. The water is rectified by the fins 12 and returned to the room.

In this way, while the indoor air is dedusted and sterilized by forced circulation, it is further sterilized by the discharge tube 8 installed outside the cylindrical reflector 4.

In addition, the objects installed and stored indoors, such as instruments, are also sterilized by the sterilizing rays of the external discharge tube 8.

When one hour has passed in this state, all the discharge tubes 8a, 8 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 internal discharge tube 8a: 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.

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 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.

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 both the inner and outer discharge tubes 8a, 8 are lit and used at the same time, only the inner 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 for example, the cylindrical reflector may be not an upright type but a sideways type, and if it is cylindrical, it is not limited to a cylindrical shape, but a rectangular cylindrical shape. It does not matter whether the cross section is doglegged, inverted doglegged, trapezoidal, inverted trapezoidal, or any other shape depending on the desired reflection angle. It goes without saying that the design can be changed as appropriate within the scope of the invention.

Since the germicidal lamp device according to the present invention has the above-described configuration, it can easily remove dust from the indoor air of each room with a simpler and cheaper device than conventional devices.
Alternatively, it can uniformly and quickly sterilize indoor ceilings, walls, floors, installed objects, surgical instruments, etc., and since it is movable, the device can be moved to the desired position depending on the indoor conditions. The efficiency of surface utilization can be increased.

In addition, with this device, indoor air is forced to circulate inside the cylindrical reflector using 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 external sterilizing lamp is sterilized again by the internal sterilizing lamp, resulting in a significant sterilizing effect.

Furthermore, in the case of a cylindrical reflector in which the external germicidal lamps are turned on simultaneously or separately, for example, at night, when no one is in or out of the room, Sterilization lamps are turned on at the same time to remove dust from the indoor air and sterilize everything in the room, such as in operating rooms during surgeries, surgical equipment rooms, hospital rooms, examination rooms, outpatient waiting rooms, etc. where there are people in the rooms. In such cases, only the internal sterilizing lamp is turned on, allowing dust removal and sterilization of the indoor air to be carried out without the harmful rays of the sterilizing lamp 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.
