Description

Detailed Description of the Invention

Technical field belonging to the invention

Although the present invention is compact, ozone and tap water are mixed to produce high-concentration ozone water. A plurality of ozone generators are connected in series, and the ozone water concentration is increased by a combination of a plurality of high-voltage power supplies. I can do things. The present invention relates to an apparatus for sterilizing an inflow or outflow of ozone water in a reaction tank with a certain amount of discharge while washing instruments in an ultrasonic case with running water.

In this case, sterilization is mainly performed for ophthalmic surgical instruments. Conventionally, sterilization is performed using an autoclave, but this is done by placing the surgical instrument tip (scalpel), knife, handpiece, etc. in a cassette and pushing it into the boiler and closing the lid. Sterilize with steam and pressure (1.3 kg). At the end of sterilization, the built-in compressor is activated to discharge the high-temperature steam in the cassette, forcibly ventilate and cool to dry. During this time, sterilization is completed in about 1 hour.

Problems to be solved by the invention

Sterilized instruments are always required for eye surgery. It is required that the autoclave sterilization time be greatly shortened and that even a single chip can be easily sterilized and washed.

Furthermore, one chip is priced at 50,000 yen or more, and there is a handpiece with more than 1,500,000 yen.

6 people at a time, 6 sets of surgical instruments are required for eye surgery. The amount is over 9 million yen. In the case of 10 people, about 15 million yen will be stocked.

Means for solving the problem

Therefore, it is a method of sterilizing surgical instruments with high-concentration (20 ppm) ozone water instead of an autoclave.

First, the lid of the cleaning case with the ultrasonic device is opened, and a rubber sheet with protrusions and holes is laid. Then, the instruments are arranged at intervals with the lid closed, and the switch is turned on.

Sterilized in 5 to 10 minutes in advance with a timer set, and the time is much shorter than before, so the average surgery time is about 15 to 20 minutes, so two or three can be adequately covered.

The ultrasonic ozone water sterilization cleaning apparatus according to the present invention will be described.
As shown in FIG. 2, tap water flows from the ejector (7) mixer (8) into the reaction tank (9) through the electromagnetic valve (5), and in this case, the ozone inlet (7a) of the ejector (7). More ozone is supplied.

As shown in FIG. 4, this ozone is supplied to an ozone inlet (7a) from a separately provided ozone generator (14) through a check valve (4) and can be mixed with tap water.

As shown in FIG. 4, the ozone generator (14) is a quartz double tube with one side blocked inner tube (15) being a positive electrode and an outer tube (16) provided with an inlet / outlet and a heat sink (17) inserted into it. The negative electrode can be used as a negative electrode to connect the entrance / exit of the double pipe (14), thereby simplifying and reducing the cost.

The double pipes are then used as parallel pipes, and a plurality of such double pipes are arranged and oxygen (1) is introduced and discharged from one of the inlets, whereby high-concentration ozone can be supplied on the outlet side.

As shown in FIG. 2, the static mixer (8) next to the ejector (7) uses a static fluid mixer disclosed in JP-A-4-135633. For this reason, ozone water is further decomposed, inverted, and converted, so that the mixing ratio is increased.

The ozone bubble water flows into the reaction tank (9), and the exhaust ozone is decomposed into oxygen by the catalyst (10) and discharged into the atmosphere.

On the other hand, the ozone water gradually increases in the reaction tank (9), and when it reaches the float (9a) at the upper part of the discharge pipe (9c), the lid (9b) is gradually opened and the slow water flows and fills automatically. It is a mechanism to prevent.

When ozone water coming out of the outflow pipe (8b) and the exhaust pipe (9c) is separated by the three-way valve (11) and flows into the ultrasonic case (14) for cleaning the instrument, the other hand is washed, washed eyes, deodorized, etc. It can be warmed with a heater (12) and the concentration of ozone water can be adjusted.

Hereinafter, an ozone water sterilizer according to an embodiment of the present invention will be specifically described with reference to the accompanying drawings. FIG. 2 is a schematic diagram showing an ozone water sterilization cleaning apparatus according to the present invention, and FIG. 1 is a schematic diagram showing the entire ozone water sterilization cleaning apparatus according to the present invention. FIG. 3 is a cross-sectional view showing an ozone generator of the ozone water sterilization cleaning apparatus according to the present invention. FIG. 4 is a cross-sectional view showing the flow of exhaust ozone in the reaction vessel and the flow preventing the increase of ozone water due to floating.

As shown in FIG. 2, the amount of ozone generated decreases as the summer temperature rises in the middle of the ejector (7) via the solenoid valve (5), so that the water temperature needs to be lowered.
Therefore, the Peltier (6) is installed in the aluminum block (6a) into which the mixer (8) is inserted, and quickly brought to the low temperature water so that the ozone water concentration is not lowered.

As shown in FIG. 4, the bottom of the reaction tank (9) is connected to the exhaust pipe (9c) with a hinge (9d) at the end of the lid (9b) with the floating (9a) upright on the exhaust pipe (9e), Prevents leakage of ozone and ozone balance by leveling without gaps.

The ozone water from the inflow pipe (8a) of the reaction tank (9) is slightly reduced in diameter so that the exhausted ozone does not flow with the ozone water into the outflow pipe (8b). The ozone water gradually increases and reaches the float (9a), and eventually the lid (9b) opens gradually and over water flows and the ozone water is always automatically raised and lowered to maintain the balance. It is a mechanism to take.

As shown in FIG. 3, it is possible to generate high-concentration ozone by injecting oxygen from a medical oxygen cylinder by connecting four parallel tubes (14) each having two electrodes (15) in series.

Hereinafter, the test results conducted for demonstrating the effects of the present invention will be described in detail. The concentration of ozone water generated using this ozone water generator was measured using a water amount of 2 liters per minute and medical oxygen of 1 liter per minute under conditions of an air temperature of 12 ° C, a water temperature of 10 ° C and a humidity of 50%.

This ozone water concentration measuring instrument is an OZW3-25P product from Higuchi Yamato Kogyo Co., Ltd. and measured by comparison with the product made by Aplix Co., Ltd. did it.

As described above in detail, according to the present invention, one to four sets of parallel type ozone generator tubes are connected upright, and the maximum amount of ozone can be obtained by concentrating the oxygen amount in one place below 1 liter. Thereby, the bactericidal effect of ozone mixed water can be made high.

Moreover, the internal device can be housed in a 30 cm square, and the device can be downsized (one third of the conventional size), the device structure can be simplified, the number of parts can be reduced, and the weight can be reduced. Therefore, these improvements can reduce the cost of the manufacturing apparatus.
