Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolyzed water producing apparatus for producing and supplying electrolyzed water for sterilization and disinfection.

[0002]

2. Description of the Related Art For example, in fields such as agriculture and food,
Useful electrolyzed water produced by electrolysis,
Is generally known. In particular, in recent years, attention has been paid to excellent sterilization and disinfection effects of electrolyzed water, and its use in the medical field, for example, sterilization and disinfection of affected areas, incisions, percutaneous openings of indwelling catheters, etc., has been studied. There is.

In order to increase the electric conductivity of the electrolyzed water, such electrolyzed water is added with a solute which produces ions by dissolution, for example, sodium chloride, potassium chloride, magnesium chloride, calcium carbonate or the like, and if necessary. It is obtained by electrolyzing water (electrolyzed water) added with a strong acid for pH adjustment.

The electrolysis is carried out using an electrolytic cell having an electrode pair consisting of an anode and a cathode, or an electrolytic cell having a structure in which a diaphragm is arranged between the anode and the cathode. As a conventional device for generating such electrolyzed water, one in which the device is directly connected to a water supply pipe such as a water pipe, and the electrolyzed water is stored in a water storage tank in the generation device and electrolyzed in the water storage tank. There is a method in which electrolyzed water is generated and stored by taking out the above process, and a required amount of this electrolyzed water is taken out when needed.

The former device is suitable for producing a large amount of electrolyzed water for industrial use, but since the device is large and the place of use is limited to the vicinity of a water supply facility,
It is not suitable for using a small amount (for example, about 200 to 500 cc) of electrolyzed water in a hospital or a household. For example, when it is used for sterilization and disinfection of the exit portion of an indwelling catheter in continuous portable peritoneal perfusion (CAPD), it is small and easy to handle when it is used by the patient at home. It needs to be a convenient device.

The latter device (electrolyzed water storage type device)
Although it is possible to manufacture a relatively small device, it has a number of drawbacks. Since the amount of electrolyzed water used in an electrolyzed water storage device cannot be predicted, it is necessary to electrolyze and store a certain amount of electrolyzed water in consideration of the range of increase or decrease in the amount of use. . That is, for example, 200
Even when using a small amount of electrolyzed water of ~ 500cc, 1
It is necessary to electrolyze more than liter of electrolyzed water and store it.

If the electrolyzed electrolyzed water is stored and stored in a water storage tank and is used when necessary, the characteristics of the electrolyzed water are deteriorated. That is, since the activity of electrolyzed water decreases over time due to light irradiation, contact with the atmosphere, and the like during storage, the sterilization and disinfection effects decrease. In particular, sterilization and disinfection effects vary depending on the storage time of electrolyzed water.

In consideration of the decrease in activity during storage, it is possible to carry out electrolysis in advance under electrolytic conditions so that the activity becomes high. Since it is not possible to predict the time from generation of electrolyzed water to use, the activity of electrolyzed water during use, that is, the sterilization and disinfection effects, also varies.

It is also possible to re-electrolyze electrolyzed water that has been electrolyzed once (electrolyzed water that has been stored or stored) to be electrolyzed again to restore its activity. In this case, however, In order to properly set the electrolysis conditions such as the electrolysis current, it is necessary to understand the characteristics such as pH of the electrolyzed water, residual chlorine concentration, and electrical conductivity. Therefore, it is necessary to measure those values and perform re-electrolysis according to the measured values. However, such measurement and setting of conditions take a lot of time and are not practical.

Further, when a small amount of electrolyzed water is used, it is necessary to dispose of extra electrolyzed water or electrolyzed water that has passed the effective storage time, but electrolyzed water has a metal corrosive property. Some of them are expensive, and if such electrolyzed water is directly discarded into a drainage channel, problems such as corrosion of the drainage channel and pollution such as water pollution will occur. Therefore, the disposal of electrolyzed water should be avoided as much as possible.

As shown in FIG. 4, inside the container 21,
A predetermined amount of electrolyzed water 25 is stored. Electrolyzed water 25
Examples thereof include an aqueous solution in which an electrolyte such as sodium chloride, potassium chloride or magnesium chloride is dissolved. Hereinafter, the electrolyzed water 25 will be typically described with an aqueous sodium chloride solution.

An additive solution such as hydrochloric acid may be added to the electrolyzed water 25 in order to enhance the activity of the electrolyzed water 26 obtained. Moreover, such an addition liquid may be added at the time of use.

A liquid feed pump 6 is installed on the upper portion (lid portion 211) of the container 21 as a liquid feed means. As shown in FIG. 5, the liquid feed pump 6 in this reference example is a turbo type pump, and includes a casing 61, a rotor 64 rotatably installed in the casing 61, and a casing 61.
And a motor 66 that rotates the rotor 64.

A plurality of blades 65 are installed on the rotor 64 at equal intervals. Further, a discharge port 62 projecting in the tangential direction of the inner peripheral surface of the casing 61 is formed on the outer peripheral portion of the casing 61, and a proximal end of a tube 70 described later is connected to the discharge port 62. . Casing 6
Three suction ports 63 are formed in the bottom portion of 1. The rotating shaft 67 of the motor 66 is fitted in the center of the rotor 64.

An upper end of a pipe 72 is connected to each suction port 63 via a connector 71 penetrating the upper portion of the container 21, and a lower end of the pipe 72 is immersed in the electrolyzed water 25.

In such a liquid feed pump 6, a motor 66 is used.
When the rotor 64 rotates clockwise in FIG. 5, the electrolyzed water 25 in the container 21 is sucked into the casing 61 from each suction port 63 through the pipe 72 and the connector 71, and is further accelerated in the casing 61. Then, the liquid is discharged from the discharge port 62 and transferred to the operation unit 3 through the tube 70.

The liquid feeding path 7 is formed by the inner cavity of the pipe 72, the inside of the connector 71 and the casing 61, the inner cavity of the tube 70 and the internal flow passage 31 of the operation portion main body 30 which will be described later.

The operating section 3 has an operating section main body 30 having an internal flow path 31, and a lever 33 rotatably installed with respect to the operating section main body 30. A grip portion 32 for gripping with a hand is formed on the lower portion of the operation portion main body 30. The lever 33 is urged in the tip direction, that is, in the direction away from the grip portion 32, by urging means such as a torsion spring (not shown) installed near the rotation fulcrum.

Further, the electric field section 4 is built in the operation section main body 30, and the ejection nozzle 5 communicating with the internal flow path 31 is formed (or connected) at the tip of the operation section main body 30. At the base end of the operation portion main body 30, its inner cavity has an internal flow path 3
The tip of the tube 70 is connected so as to communicate with 1. The tube 70 has flexibility, and for example,
It is composed of a high molecular material such as polyvinyl chloride, polyethylene, polypropylene, polyolefin such as ethylene-vinyl acetate copolymer (EVA), polyamide, polyester, silicone rubber, polyurethane and the like.

The electric field section 4 includes an electrolytic cell 40 formed in the middle of the internal flow path 31, an electrode pair composed of a plate-shaped anode 41 and a cathode 42 arranged facing each other in the electrolytic cell 40, and an electrode pair. And an energizing circuit 43 to the. As the anode 41 and the cathode 42, for example, a metal plate made of titanium plated with platinum can be used, but needless to say, it is not limited to this structure.

The energizing circuit 43 has a power source (DC power source) 44.
And a current control circuit 45 for controlling the current applied to the electrode pair.
And a switch 46. The positive terminal of the power supply 44 is connected to the anode 41 via the current control circuit 45, and the negative terminal of the power supply 44 is connected to the cathode 42.

The switch 46 has an operating piece 47 projecting toward the lever 33 on the tip side of the grip portion 32. The operating piece 47 is biased toward the tip by a spring (not shown) to form a normally open switch.

When electricity is not supplied in the meantime, electricity is not supplied to the motor 66 and the liquid feed pump 6 is stopped.

A power supply control circuit can be used instead of the current control circuit 45. In this case, the power supply control circuit may have a function of independently controlling the application of the voltage to the electrode pair and the power supply to the motor 66, for example.

In the electric field section 4 as described above, electricity is applied between the anode 41 and the cathode 42, and in this state, when the electrolyzed water 25 sent by the operation of the solution sending pump 6 passes through the electrolytic cell 4, The electrolyzed water 25 is electrolyzed, and by the reaction shown by the following formula, hypochlorous acid (HClO) is generated on the anode 41 side, and sodium hydroxide (NaOH) and hydrogen gas (H2) are generated on the cathode 42 side. Electrolyzed water containing these 26
Is obtained. Then, this electrolyzed water 26 is ejected from the nozzle 5.

When the grip of the lever 33 is released, the energization of the electrode pair and the energization of the motor 66 are stopped, and the generation and ejection of the electrolyzed water are stopped. When the electrolyzed water 25 in the container 21 becomes empty, the electrolyzed water 25 can be replenished in the container 21 and the use can be continued.

As described above, in the electrolyzed water producing apparatus 1A,
By operating the lever 33 in the operation unit 3, the generation of the electrolyzed water 26 by the operation of the electrolysis unit 4 and the ejection of the electrolyzed water 26 from the ejection nozzle 5 by the liquid feeding are performed in synchronization. Then, while the lever 33 is being held, the electrolyzed water 26 is jetted out.
It is possible to adjust the cumulative ejection amount of 6.

Further, the operating portion 3 is relatively small and lightweight, is separated from the storage portion 3 and is connected by a flexible tube 70 so that its posture and position can be freely set, so that the electrolyzed water is used. The operation of ejecting 26, in particular, the operation of ejecting electrolyzed water onto a living body by a doctor, a nurse, the patient himself or the like can be performed very easily.

The jet nozzle 5 is not particularly limited in its form and the like. For example, the jet nozzle 5 can jet the electrolytic water 26 linearly (as a jet), the jet nozzle 26 can jet the electrolytic water 26 in a shower shape, Anything may be used, such as one capable of spraying the electrolyzed water 26 in the form of mist. The former case is suitable for cleaning with electrolyzed water (cleaning with sterilization and disinfection).

In the illustrated construction, the ejection nozzle 5 is integrally formed or fixed to the operation section main body 31, but it may be detachable from the operation section main body 31.

The container 21 is the same as that of the reference example 1, and an upper part (lid part 211) is provided with a liquid feeding means.
A pressure pump 8 is installed. As shown in FIGS. 7 to 9, the pressurizing pump 8 in the present reference example is a manual pump, and is mainly a cylinder 80 installed so as to project into the container 21 and inserted into the cylinder 80. The plunger 81 and the gasket 82 installed at the lower end of the plunger 81. The gasket 82 is
As the plunger 81 reciprocates, the plunger 81 slides airtightly against the inner surface of the cylinder 80.

An opening 83 is formed at the bottom (lower end) of the cylinder 80, and a valve 85 capable of opening and closing the opening 83 is installed. An opening 84 is formed in the gasket 82, and a valve 86 that can open and close the opening 84 is installed.

As shown in FIG. 8, when the plunger 81 is pulled upward, the valve 86 opens the opening 84 and the valve 85 opens.
3 is closed, the volume of the space 87 surrounded by the cylinder 80 and the gasket 82 is increased, and air is introduced into the space 87 through the opening 84.

As shown in FIG. 9, when the plunger 81 is pushed downward, the valve 86 closes the opening 84 and the valve 85 opens 8.
3 is opened, the volume of the space 87 is reduced, air is discharged from the space 87 through the opening 84, and this air is injected into the container 21. By vertically moving (reciprocating) the plunger 81 a predetermined number of times, the inside of the container 21 can be pressurized to a predetermined pressure.

The base end of the tube 70 is connected to the upper end of the pipe 72 via an L-shaped pipe 73. In this reference example,
The pipe 72, the L-shaped tube 73, the lumen of the tube 70, and the internal flow path 31 of the operation section body 30 form the liquid supply path 7.

The operation section 3 has the same internal flow path 31 as described above.
Also, it has an operation portion main body 30 having a grip portion 32, a lever 33, an electrolysis portion 4, and an ejection nozzle 5.
The distal end of the tube 70 is connected to the proximal end of the operation portion main body 30 so that its inner cavity communicates with the internal flow path 31.

The packing 93 made of an elastic material is closely attached to and separated from the packing 93 to open and close the flow path to the ejection nozzle 5.

In the electrolyzed water producing apparatus 1B having the above-described structure, when used, first, the pressurizing pump 8 is operated as described above to pressurize the container 21 to a predetermined pressure. In this state, the pressure in the internal flow path 31 is also increased by the pressurization, but in the state where the lever 33 shown in FIG. 10 is not gripped, the lever 33 is positioned on the tip side by the biasing means described above. Switch 46 is open, and
The poppet valve 90 closes the ejection nozzle 5 and thus

Next, as shown in FIG. 11, when the lever 33 is grasped and rotated in the proximal direction, that is, in the direction approaching the grip portion 32, in the operation portion 3, the switch 45 is closed in the same manner as described above. The current control circuit 45 operates to energize the electrode pair. At the same time, the displacement of the valve actuation mechanism 91 causes the poppet valve 90 to move in the proximal direction, and the ejection nozzle 5 opens. Since the inside of the container 21 is pressurized, the electrolyzed water 25 stored in the container 21 is transferred to the internal flow path 31 through the pipe 72, the L-shaped pipe 73, and the tube 70 in order, and the electrolyzer 40 is operated. When it passes, it is electrolyzed and becomes electrolyzed water 26, which is ejected from the ejection nozzle 5.

When the grip of the lever 33 is released, the energization of the electrode pair is stopped, the poppet valve 90 is closed, and the generation and ejection of the electrolyzed water are stopped. Such an electrolyzed water producing apparatus 1B has the same operation and effect as the electrolyzed water producing apparatus 1A, and since the liquid feeding means is constituted by the manual pressurizing pump 8, no electric power is required, There is an advantage that it can be made lighter and smaller.

On the upper part (lid 211) of the container 21, a pressure pump 8 similar to the above is installed as a liquid feeding means. When the pressure pump 8 is actuated to pressurize the inside of the container 21, the bag body 22 is compressed, and the electrolyzed water 25 in the bag body 22 flows out from the outflow port 23 by gripping the lever 33, and the L-shaped tube is drawn.
