JPS6021088Y2 - Intake air purifier for indoor pollutants due to surgery - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an intake air purifier that sucks and purifies indoor contaminants such as smoke, bacteria, and odor generated during surgery using a laser scalpel, an electric scalpel, or the like.

Conventionally, an intake air purifying device has been used to prevent the above-mentioned indoor pollutants from filling an operating room or the like and thereby preventing a doctor from performing a surgical operation.

However, since this type of device simply uses a granular activated carbon filter to purify the water, it is necessary to incorporate a fairly large filter due to the characteristics of the activated carbon.
For this reason, it not only becomes extremely large and difficult to operate, but also has a fairly good purifying ability for smoke and odors contained in indoor pollutants, but does not purify airborne bacteria. It was enough.

The present invention is an attempt to solve the above-mentioned difficulties of conventional devices, and aims to reduce the size and improve the purification ability by arranging filters for bacteria and filters for smoke and odor at appropriate locations. , is its purpose.

To describe the present invention in detail with reference to the illustrated embodiment, a cylindrical container body 1 is composed of a base cylinder part 2 and a cap 4 pivoted to the distal end thereof by a hinge 3 so as to be able to open and close freely. The opening/closing device for the cap 4 is shown.

A bacterial filter 6 is attached to the head end of the cap 4.
is fixedly installed, and the intake hose 8 shown in FIG.

In this case, as the bacterial filter 6, one in which microfibers made of acrylic resin are bundled can be used, and when this is used, it is possible to remove bacteria even if it is small and lightweight.

Next, in the above-mentioned container body 1, a motor blower 10 is fixedly installed in the base cylinder portion 2 by a suitable support member 11, and numeral 12 in the figure indicates a rubber isolator of the same member 11.

Furthermore, this support body 11 is provided with a smoke and odor pre-stage filter 13, but in the illustrated example, a tapered inner mesh tube 16 is provided protruding from a mounting ring 15 fixed to the support body 11 with screws 14. A tapered outer mesh tube 18 is fitted on the outside of the front-stage filter main body 17 mounted on the tube 16, and a closing plate 19 fixed to the narrow end of the inner mesh tube 16 has an outer The pre-stage filter 13 is constructed by stacking the fixing plate 20 fitted on the narrow end of the mesh tube 18 and attaching it to the closing plate 19 with fixing screws 21. In the figure, 22 indicates the support 11 The intake guide port is opened to the intake side of the motor blower 10, and it is preferable to use activated carbon in the form of felt for the pre-stage filter main body 17.

Further, a smoke and odor rear filter 23 is closed in the rear end opening 1' of the vessel 1, and in the illustrated example, a plate-shaped rear filter 24 is sandwiched between inner and outer mesh plates 25 and 26. By fixing this with screws 27, the latter stage filter 23 is constructed, and the motor blower
10 exhaust ports 28 serve as the smoke and odor downstream filters 23.
The direction is open in the central part.

Fig. 4 shows the intake air purifier according to the present invention attached to the wheeled main body A' of the laser surgery device A. In this case, the two are connected by an electric signal line B, and the air purifier is attached to the wheeled main body A' of the laser surgery device A. By stepping on and closing the derived foot switch C, the laser surgery device A is operated, and at the same time,
The intake air purifier of the present invention is also activated, thereby immediately sucking indoor contaminants such as bacteria, odor, smoke, etc. caused by the use of the laser scalpel from the intake hose 8, and furthermore, by opening the switch C, the laser surgery device It is desirable to stop the operation of the intake air purifier after a predetermined delay time set by a timer or the like after the operation of A is stopped, thereby measuring the suction of necessary indoor pollutants.

Therefore, when the device having the above configuration is operated, the intake air sucked from the intake hose 8 by the rotating operation of the motor blower 10 passes through the bacteria filter 6 from the intake lower and flows into the body 1, but the filter 6 bacteria will be removed).

Furthermore, the intake air flowing into the container body 1 sequentially passes through the outer mesh tube 18 of the smoke and odor pre-filter 13, the pre-filter main body 17, and the inner mesh tube 16, and then passes through the intake guide port 22 to the motor blower. The intake air that flows out from the exhaust port 28 of the blower 10 passes through the smoke and odor filter 23 and is discharged to the outside air.
Purification is carried out at three locations to remove smoke and odors.

As embodied in the above-mentioned embodiment, the present invention has a bacteria filter 6 fixed at the tip of the container 1 through which air flows in from the suction lower and which flows into the container 1 from the inlet 9. Inside the container 1 is a motor blower 10, and on the intake side of the blower 10, there is smoke through which the intake air passes.
In addition, the rear end opening 1' of the vessel 1 is provided with a rear filter 23 for smoke and odor through which the intake air flowing out from the exhaust port 28 of the motor blower 10 is passed and released. Since it is a closed structure, the overall size can be reduced by installing a small and lightweight bacterial filter 6, and the purification ability against bacteria can be dramatically improved. Then smoke,
Since the pre-filter 13 for odor is provided, indoor pollutants are further purified, and after the purified intake air passes through the motor blower 10, it is passed through the post-filter 2 for smoke and odor.
Since it undergoes purification again in step 3, it can be expected that smoke and odor will be sufficiently purified.
