The filter mounting plate 68 is formed at an appropriate position corresponding to 20.

On the other hand, the five air discharge ports 50 through which the clean air discharged from the filter unit 53 is distributed and discharged.
The air discharge port unit 50A provided with is attached and installed in the upper internal portion of the front side of the housing 5 in a back-to-back positional relationship with the filter unit 53. The air discharge port unit 50A includes a main pipe 80a with a closed tip that is connected to the filter unit 53 by a communication pipe 74 (see FIG. 5c), and five branch pipes for air discharge that are branched from the main pipe 80a. The structure consists of 80b. The above-mentioned air check 21 is provided at the tip of each branch pipe 80b, and the above-mentioned regulator 29 is screwed and fixed to the inlet of the main pipe 80a.

Therefore, the air outlet unit 50A provided with the regulator 29 is also a unitized separate component, and, as shown in FIG. 6, is attached to and supported by the operation face plate 56, and the operation face plate 56. Is fitted into a mounting opening 75 opened in an upper portion of the front wall of the box 5, and then detachably assembled and fixed to the box 5 by screws 55 on the left and right side surfaces. Therefore, even the air discharge port unit 50A can be easily incorporated into the box body 5, and the maintenance such as the pressure adjustment of the regulator 29 and the cleaning of the air discharge port unit 50A can be easily performed by the removable structure.

FIG. 8 shows an example of the regulator 29.

In the figure, the regulator 29 comprises a main body unit 29a for reducing the pressure of the high pressure clean air to low pressure clean air, and an upper unit 29b for setting the pressure of the low pressure clean air.

In the main unit 29a, high-pressure clean air flows into the high-pressure chamber 29c through the communication port 29d, and the low-pressure chamber 29e and the high-pressure chamber 29c provided on the upper part of the main unit 29a are connected to the communication hole 29f.
Have been contacted via. Further, the communication hole 29f is provided with a communication port 29g for taking out low-pressure clean air.

The upper unit 29b includes a low pressure chamber 2
A chamber 29h is formed so as to communicate with 9e, and a diaphragm 29i is arranged so as to partition the chamber 29h and the low-pressure chamber 29e.

In the chamber 29h of the upper unit 29b, a pressure adjusting spring 2 for pressing the diaphragm 29i from above is used.
9j is housed therein, and a pressure adjusting screw 29k for adjusting the free length of the pressure adjusting spring 29j is screwed into the room 29h from above.

In addition, the connecting hole 29f of the main body unit 29a
The stem 2 for pressing the diaphragm 29i from below.
A ball valve 29n and a valve spring 29p are provided below the stem 29m. As a result, the force of the valve spring 29p is transmitted to the stem 29m via the ball valve 29n and presses the diaphragm 29i from below.

With the above construction, the pressure adjusting spring 2 is provided in a state before the high pressure clean air is introduced into the high pressure chamber 29c.
The force exerted by 9j on the diaphragm 29i is the valve spring 29p.
Therefore, the ball valve 29n opens the opening of the communication hole 29f on the high-pressure chamber side as shown by the solid line in FIG.

In this state, when the high-pressure clean air flows into the high-pressure chamber 29c, the high-pressure clean air flows into the low-pressure chamber 29e through the communication hole 29f, whereby the high-pressure clean air flows into the low-pressure chamber 29e.
The air pressure in the low pressure chamber 29e rises.

Then, the combined force of the force acting on the diaphragm 29i by the air pressure of the low pressure chamber 29e and the force acting on the diaphragm 29i by the stem 29m by the valve spring 29p is generated by the pressure adjusting spring 29j.
If it becomes larger than the force acting on the diaphragm 29i,
Deforms upward, and as a result, the ball valve 29n closes the opening of the communication hole 29f on the high-pressure chamber side, as indicated by the broken line in FIG.

As a result, the high pressure clean air does not move from the high pressure chamber 29c to the low pressure chamber 29e.

On the other hand, the high pressure clean air is supplied to the low pressure chamber 29e.
From the time of flowing into the
When the (high-pressure) clean air that has flowed in through f flows out and the ball valve 29n closes the opening of the communication hole 29f, the air accumulated in the low-pressure chamber 29e passes through the communication hole 29f and the communication opening 29g, It flows out.

In this way, when the air accumulated in the low pressure chamber 29e begins to flow to the outside, at this time, the high pressure chamber 29c moves from the low pressure chamber 29c.
Since there is no air flow to e, the air pressure in the low pressure chamber 29e gradually decreases. When the combined force of the force exerted on the diaphragm 29i by the air pressure of the low pressure chamber 29e and the force exerted on the diaphragm 29i by the stem 29m by the valve spring 29p is smaller than the force exerted on the diaphragm 29i by the pressure regulating spring 29j, The diaphragm 29i moves so as to return to the original state, whereby the ball valve 29n releases the opening of the communication hole 29f on the high pressure chamber side.

As a result, high-pressure clean air flows from the high-pressure chamber 29c to the low-pressure chamber 29e, the air pressure in the low-pressure chamber 29e rises, and as described above, the force acting on the diaphragm 29i by the air pressure in the low-pressure chamber 29e and the valve The combined force of the force exerted by the stem 29m on the diaphragm 29i by the spring 29p is the pressure adjusting spring 29j.
Becomes larger than the force acting on the diaphragm 29i,
The diaphragm 29i is deformed, and the ball valve 29n closes the opening of the communication hole 29f on the high pressure chamber side.

By repeating the above operation, the high-pressure clean air that has flowed in through the communication port 29d is temporarily stored in the low-pressure chamber 29e, and then flows out through the communication port 29g to the outside. The pressure is adjusted to a value corresponding to the acting force of the pressure adjusting spring 29j. Here, the pressure adjusting spring 29j is adjusted and set to a spring pressure such that air having a pressure that almost completes the inhalation treatment time when the mist of the liquid medicine 11b necessary for the treatment is discharged is, for example, 5 minutes. To be done. As an example of a specific pressure setting, when the pressure of the high-pressure clean air accumulated in the tank 28 is set to 1.2 atm and the depressurized value of the regulator 29 is set to 0.6 atm, the treatment time is about 5 minutes. become.

FIG. 9 shows an example of the atomizer.

In the figure, a nozzle 11a is provided at the center of the atomizer body 11 on the inlet side.
A chemical liquid reservoir 11c for accumulating the chemical liquid 11b is provided around 1a.

The atomizer main body 11 is gradually tapered from the upper portion of the chemical liquid reservoir 11c and is squeezed from a position slightly beyond the tip of the nozzle 11a to form a mixing portion 11d inside and to the discharge port 11e. I am in touch.

Therefore, when low-pressure clean air is sent to the atomizer main body 11, this low-pressure clean air is throttled by the nozzle 11a to increase the speed and is discharged from the nozzle 11a. Since this high-speed airflow entrains the air around the portion from the tip of the nozzle 11a to the mixing section 11d, the air in the space above the chemical solution reservoir 11c becomes a negative pressure, and the chemical solution 11b is vaporized and sent to the mixing section 11d. Be done.

As a result, in the mixing section 11d, the vaporized chemical liquid 11d is mixed with the clean air discharged from the nozzle 11a, and the mixed gas is discharged from the discharge port 11e.

In this way, from the atomizer body 11,
A mist containing the chemical liquid 11d is discharged.

In order to carry out inhalation treatment using this device, the spray device can be moved. For example, in the case of an inpatient, the spray device can be moved from the nurse station or the like which it normally administers to the patient's room. To use. In the case of an outpatient, the patient should be moved to a prescribed treatment room in the hospital and placed at that location so that privacy can be protected and treatment can be received. For example, when the main spray device is carried to a patient room and the power switch 23 of the main body device 1 is turned on, the pressure switch 2
Power is supplied to the compressor 6 via 4, whereby the compressor 6 operates and high-pressure air is discharged.

This high-pressure air flows into the tank 7, and the high-pressure air accumulated in the tank 7 is sequentially purified through the air pressure filter 18, the oil mist separator 19 and the deodorizing filter 20 to become high-pressure clean air and regulator. Enter 29. Then, after being reduced to a pressure set by the regulator 29 to become low-pressure clean air, it is distributed from the main pipe 80a of the air discharge port unit 50A to each branch pipe 80b and reaches each air chuck 21. At this time, since the high pressure air is closed by the air chuck 21, the pressure of the high pressure air in the tank 7 gradually increases, and when the pressure reaches the set pressure, the pressure switch 24 is turned off, whereby the compressor 6 of the compressor 6 is turned off. The operation stops.

In this way, when the power switch 23 of the main unit 1 is turned on, the compressor 6 starts operating, and when the pressure of the high pressure air accumulated in the tank 7 reaches the set value, the operation of the compressor 6 is stopped. To do. The pressure in the tank 7 is measured by the pressure gauge 69 attached to the tank 7.
(Refer to Fig. 6) Since it can be confirmed by the nurse who handles the operator or the user (patient), he / she notices an abnormality or failure from the pressure value, and stops the operation for safety or prompt repair. You will be able to respond quickly and accurately. After the operation of the compressor 6 is stopped, the high pressure air in the tank 7 is discharged to the atomizer 2 by the air tube 3 connected to the air outlet 50, and the air pressure in the tank 7 becomes smaller than the set value. The pressure switch 24 is turned on again, whereby the compressor 6
Since the power is supplied to, the accumulation of high pressure air in the tank 7 is restarted.

Next, in order to draw the high-pressure air accumulated in the tank 7 into the atomizer 2, the sealing valve 31 at the tip of the air tube 3 of the atomizer 2 is attached to the air chuck 21 of the main body device 1. To do.

As a result, the closed state of the air chuck 21 is released at the air discharge port 50 to which the air tube 3 is connected, so that the air is discharged from the tank 7 and the air pressure filter 18, the oil mist separator 19 and the deodorizing filter 20 are discharged. The high-pressure clean air that is sequentially purified and formed is converted into low-pressure clean air having a set pressure by the regulator 29, and then the air check 21 and the sealing valve 31.
Through the open air outlet 50 to the air tube 12
To reach the atomizer 2 and the chemical liquid 11b is atomized,
The nozzle 11a of the atomizer 2 emits a fog of the drug solution 11b, so that the patient can be treated. With such a movable spraying device, inpatients can receive treatment in the hospital room without going to the treatment room as in the past.
The burden is light and it is convenient because you can easily receive medical treatment when needed.

When the present spraying device is placed in a predetermined treatment room to accommodate outpatients, the atomizers 2 for the number of patients are prepared and the air tubes 3 of the respective atomizers 2 are enclosed. If the valve 31 is connected to the air outlet 50 in the same manner as described above, that is, the valve 31 is attached to the air check 21, the air check 21 is released, and low-pressure clean air is sent to the individual atomizers 2 connected. Atomizer 2 to chemical 1
A fog of 1b is emitted, and a large number of patients (five in this example) can be treated at the same time. In this way, inhalation therapy can be performed simultaneously for multiple patients,
The labor of nurses etc. is reduced and labor saving is promoted. Also, by making it movable, it becomes possible to freely place it in an appropriate place, so if this spraying device is placed in a specific separate room,
There is also the advantage that privacy can be protected and the treatment can be treated with peace of mind without being known to others. Although the number of the air discharge ports 50 is five in the embodiment, it goes without saying that the number can be set appropriately.

By the way, in the above-mentioned embodiment, one regulator 2 is provided at the air inlet of the air outlet unit 50A.
9 has been provided to depressurize the high-pressure air to a predetermined pressure and supply the low-pressure air to the five air outlets 50.
According to 0A, when all the five air discharge ports 50 are opened, the air discharged from the regulator 29 at the air discharge port 50 far from the regulator 29 is affected by the conduit resistance of the main pipe 80a and the like, and the discharge pressure is reduced. However, there is a concern that there may be a difference in the treatment time that will result in uneven ejection status.

Therefore, if the air discharge port unit 50B having the structure shown in FIG. 10 is adopted, more stable spraying can be carried out, and a preferable spraying device can be obtained.

That is, in FIG. 10, each branched pipe 80 in the air discharge unit 50B is branched.
One regulator 29B is provided for each b. And, at the entrance of the air outlet unit 50B,
An electromagnetic valve 90 that operates by operating the power switch 23 is arranged to control the supply and stop of air to the air discharge unit 50B.

In this way, if the regulator 29B is provided for each air discharge port 50, the branch pipe 80 is adjusted by individually adjusting the pressure of the regulator 29B.
It can be assumed that air of a constant pressure is applied to reach any of b.

Therefore, after pressing the power switch 23 to open the solenoid valve 90, the air tubes 3 of the individual atomizers 2 are connected to the arbitrary air discharge ports 5 as in the case of the previous embodiment.
If it is connected to 0, the air having a constant pressure set by the regulator 29B is sent to the atomizer 2 and the fog of the drug solution 11b is discharged, so that the patient can be treated.

Even when the five atomizers 2 are connected to the five air outlets 50 and all of them are used, there is no change in the discharge pressure due to the positional distance difference from the air inlet of the air outlet 50. Air of a constant pressure is discharged from any of the air outlets 50, and stable atomization is performed from any of the atomizers 2, so that proper inhalation treatment can be performed.

Further, in the above-mentioned two embodiments, the air discharge port 50 is opened by a system in which the air chuck 21 provided therein is connected to the sealing valve 31 at the tip of the air tube 3 of the atomizer 2. As in the embodiment shown in FIG. 11, it is also possible to arrange a solenoid valve 91 in each branch pipe 80b of the air discharge unit 50C and to release air by controlling the opening / closing of the solenoid valve 91. good.

In this case, the opening / closing control is performed by the timer control for opening the solenoid valve 91 for the set time.
After setting the time, press the start switch to automatically spray for a certain period of time. As a result, the appropriate treatment time is set according to the patient such as drug type and dose, and the spray for inhaling the drug solution is automatically started.
You will be able to proceed with the treatment efficiently.

For this automated operation, as shown in FIG. 12, the timer setting switch 95 for setting the operating time (treatment time) of the solenoid valve and the setting time set by the timer setting switch 95 are displayed and the spraying is performed. A time display unit 96 for subtracting the remaining time after the start and a start switch 97 for pressing the solenoid valve 91 to energize the power source to start the opening after the time is set are provided corresponding to each air discharge port 50. There is.

As described above, since this embodiment is a spraying device of a compact size that can be moved to the user's place, the user can receive the necessary treatment at any time and place of the user regardless of the treatment place. You can

Also, since there are multiple air sources, several people can be treated at the same time, and the waiting time is shortened.
It can reduce the burden on patients and the burden on nurses involved in treatment,
You will be able to proceed smoothly with inhalation treatment.
In addition, since it can be used by connecting an inhaler to the air outlet of this nebulizer, a simple structure is sufficient for the inhaler, and it becomes possible to obtain a patient-specific inhaler at a low price, and the inhaler is easy to use. Is also greatly improved.

By the way, in the above-mentioned embodiments, the case where the present invention is applied to the therapeutic inhaler has been described. However, the present invention is applied to other spraying devices such as an airbrush for spraying paint and the like, and an insecticide. The present invention is similarly applied to a spraying device for horticulture, such as a spraying device for gardening, which is connected to the air discharge port of the main body device and is a spraying device which is suitable to spray the liquid agent using the discharged air. You can

[0069]

As described above, according to the present invention, since it is a compact and movable spraying device having a plurality of air source ports, it is possible to receive treatment in a hospital room without inpatients going to the treatment room. The burden on the patient is reduced. Also, for outpatients, if this movable spray device is placed in a specific room and inhaled, privacy can be protected. In addition, since it is possible to move, it is possible to expect a remarkable effect that can respond promptly to an emergency and can immediately respond to the urgency of effective treatment.

Further, the inhaler required for treatment has only to have a function of producing a mist of the drug by the high pressure air which is connected to the nebulizing device, so that a simple structure can be adopted, and the inhaler dedicated to the patient can be adopted. Can be provided at a low price.

Also, since there are plural air sources, it is possible to treat several patients at the same time, the treatment progresses efficiently, the waiting time is shortened for the patient, and labor saving is also performed for the nurse. Both sides can get convenience.

Further, since the air discharge port device and the filter device constituting the main body device are a unit body and can be easily incorporated and fixed in the box of the main body device, mass production effect can be expected and the device can be expected. The cost can be greatly reduced and serviceability such as repair and inspection can be improved.

Further, since the observation window for confirming the pressure in the tank is provided, it is possible to judge whether or not the spraying operation is normal and whether or not the spraying operation is normal. The effect of improving maintenance and maintaining high reliability can be obtained.

In addition to the air discharge port, the air vent port provided in the tank can also be used as an external output port, so that it is possible to connect and use another type of spray actuating device, and the range of application can be increased. It can be expanded.
