Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rechargeable hoseless sprayer for medical use, particularly for otorhinolaryngology or dental treatment.

BACKGROUND OF THE INVENTION In otorhinolaryngology or dental practice, pneumatic pressure is often used to spray a medicinal solution onto the affected area of a patient.

The treatment table used for this treatment is equipped with a compressor and the like that sends compressed air into the interior of the treatment table. The compressor is connected to a chemical sprayer by a hose. When a doctor changes the location of his medical treatment, he must hold the sprayer in his hand and move it along with the hose.

Therefore, the nebulizer with a hose not only interferes with medical treatment, but also increases the fatigue of doctors.

Therefore, there has been a strong demand for a sprayer without a hose, that is, a hoseless sprayer.

[Conventional technology]

A conventional example will be explained with reference to FIG. FIG. 2 is an explanatory diagram of a conventional example of an otorhinolaryngological spray.

In FIG. 2, reference numeral 21 denotes a chemical liquid container, which is connected to a spraying section 26 via a cap 22. 23 is an on-off valve provided on one side of the lid plug 22. When the pusher 24 is pressed by the doctor's thumb, the sliding rod 25 moves to open the on-off valve 23. Therefore, compressed air enters the chemical liquid container 21 from the pressure accumulation tank 27. When the pressure inside the chemical liquid container 21 increases, the chemical liquid is sucked up through the suction tube 29 inside the chemical liquid container 21. Thereafter, the chemical solution is sprayed in the form of a mist from the tip of the spray tube 28. The on-off valve 23 is connected to a pressure regulator 31 via an air supply pipe 30, and is detachably attached to the pressure accumulator tank 27 with a nut 32. Also,
The chemical solution container 21, the on-off valve 23, the spray section 26, and the pressure regulator 31 are integrated and can be separated from the pressure accumulation tank 27.

A leg piece 3 is connected to the lower part of the pressure storage tank 27 through an air supply port 33.
4 is installed. The leg piece 34 has an upper valve 35, and the lower part of the upper valve 35 has an upper tubular valve rod 36.
is installed. A portion of the upper tubular valve rod 36 protrudes from the guide hole of the leg piece 34.

A doctor performs medical treatment while holding Hoseless Spray A described above in his hand.

Next, the air charger for accumulating compressed air in the pressure accumulating tank 27 of the hoseless sprayer A will be explained.

The upper center of the housing 40 has a sliding groove in which the leg piece 34 is fitted and can slide up and down, and a receiving 941 into which the hoseless sprayer A is inserted is attached to the upper part of the sliding groove. There is. A sensor 42 is installed on the side of the receiving part 41.
is attached.

Therefore, hoseless spray A is not used and
If it is inserted into the receptacle 141, the sensor 42 detects this and causes current to flow through the coil 45 of the electromagnet 43.

Then, the yoke 46 supporting the coil is magnetized and attracts the leg piece 34 downward.

At this time, the upper valve 35 and the lower valve 47 open through holes not visible in FIG. 2, and are closed when the leg 34 is not suctioned.

The air charger B as described above is attached to a unit 48 on a treatment table (not shown).

In the apparatus configured as described above, the hoseless spray A is pulled out from the receiving part 41 in order for the patient to perform medical treatment. Then, the doctor
into the affected area, and then press the pusher 24 with your thumb. Pusher 2
When 4 is pressed, the on-off valve 23 opens and the compressed air accumulated in the pressure accumulation tank 27 is transferred to the pressure regulator 31 and the air supply pipe 30.
and enters into the drug solution container 21. When the air pressure inside the drug solution container 21 increases, the drug solution passes through the suction tube 29 and the spray section 26 and is sprayed from the tip of the injection tube 28 onto the affected area.

When the spray treatment is completed, the doctor inserts the hoseless sprayer A into the receiving part 41. A sensor 442 provided on one side of the receiving portion 41 detects the hoseless spray A and causes an electric current to flow through the electromagnet 43. As a result, the yoke 46 of the electromagnet 43 attracts the leg piece 34 of the hoseless spray A, which is magnetized and made of a magnetic material, together with the hoseless spray A. When the leg piece 34 is sucked downward, a valve hole not visible in FIG. 2 opens. As a result, compressed air sent from a compressor (not shown) enters the pressure accumulation tank 27 through the compressor connection 49, the lower valve 47, the upper valve 35 and the air supply port 33. After a certain period of time has passed, the pressure within the pressure storage tank 27 increases and reaches a certain pressure. Then, the pressure acts in a direction to push down the upper valve 35 and prevents the compressed air from escaping from the pressure accumulation tank 27.

At this time, the circuit of the electromagnet 43 is still operating, so
In order to prevent the electromagnet 43 from burning out, the circuit of the electromagnet 43 is cut off by a timer (not shown).

In this way, when one medical treatment is completed, preparations can be made automatically for the next medical treatment.

[Problem to be solved by the invention]

However, because it was a hoseless sprayer, there was a limit to the pressure storage capacity of the pressure storage tank. That is, when a large amount of spray is required for one medical treatment, the pressure inside the pressure accumulation tank decreases during the treatment, so the pressure must be accumulated using an air charger.

Hoseless sprayers were also separate from the air charger, requiring valves and other special structures for these connections.

Furthermore, in conventional hoseless sprayers, the chemical solution container is housed in a pressure storage tank and cannot be seen from the outside. Therefore, it was only after the doctor started spraying for medical treatment that he noticed that there was no liquid medicine.

Furthermore, since the switch for starting the spray or adjusting the strength of the spray is placed in the position of the thumb, it is difficult for the doctor to adjust the necessary amount of spray while providing treatment.

In order to solve the above problems, the present invention aims to provide a medical rechargeable hoseless sprayer that integrates a pressure accumulation tank and a compressor to simplify the structure and can constantly accumulate pressure. do.

Another object of the present invention is to provide a medical rechargeable hoseless sprayer that allows the user to visually check the usage status of a medical solution in a medical solution container.

Another object of the present invention is to provide a medical rechargeable hoseless sprayer that is easy to spray by locating the opening/closing button of the hoseless sprayer at the position of the index finger.

The compressor accumulates pressure in the pressure accumulation tank.

〔Example〕

An embodiment of the present invention will be described with reference to FIG. 1st
The figure is a schematic configuration diagram of the rechargeable hoseless sprayer according to the present invention.

In FIG. 1, reference numeral 1 denotes a drug solution container into which a drug solution is to be sprayed onto the affected area. Reference numeral 2 denotes a suction tube that sucks up the medicinal solution. When compressed air regulated by the pressure regulator 3 is sent into the suction tube 2, the medicinal solution passes through the suction tube 2 and is sprayed from a catheter (not shown) attached to the spraying section 4. .

5 is an open/close button, and when the doctor presses this open/close button 5,
The on-off valve 6 opens. Further, when the opening/closing button 5 is pressed, a valve (not shown) of the pressure regulator 30 is opened to increase the pressure inside the drug solution container 1, thereby intensifying the injection of the drug solution from the catheter. The strength of the chemical liquid jet is determined by the degree to which the open/close button 5 is pressed at this time.

7 is a pressure accumulating tank, and the pressure accumulating tank 7 and the chemical liquid container 1 are connected by a coupler 8. Therefore, the compressed air in the pressure accumulation tank 7 is sent into the chemical liquid container 1 via the coupler 8. Reference numeral 9 denotes a micro compressor, which is integrated with the pressure accumulator tank 7 via a valve 10. Further, the micro compressor 9 is provided with a pressure detector 1l. It is noted that when the pressure in the pressure storage tank 7 exceeds a specified value, the torque of the motor (not shown) of the micro compressor 9 increases. That is, the torque of the motor is detected and the micro compressor 9 is turned off based on this detection signal. Also,
A decrease in the pressure in the pressure storage tank 7 is detected by the pressure applied to the valve 10, and the micro compressor 9 is turned on based on this detection signal. Furthermore, the pressure applied to the valve 10 can be detected to turn on/off the macro, delta macro compressor 9.

A storage battery 12 is connected to a storage battery contact 13. In addition, in FIG. 1, only one terminal of the storage battery 12 is
Connected to compressor 9. However, storage battery 1
The other terminal of the micro compressor 9 is connected to another terminal (not shown) of the micro compressor 9 via the housing 14.

Furthermore, if the storage battery 12 is connected to a charging device (not shown) via the storage battery contact 13, the storage battery 12 can be charged. Therefore, doctors are not providing medical care. When the battery is needed, the storage battery 12 is charged.

The housing 14 compactly accommodates a chemical liquid container 11, a pressure regulator 3, a pressure storage tank 7, a micro compressor 9, a compressor, and a storage battery 12.

When a doctor holds this housing 14 for medical treatment, the housing 14 is shaped so that it can be easily held in the doctor's hand. In particular, the user's index finger should be placed on the opening/closing button 5, as when gripping a pistol.

Further, since the housing 14 is provided with a housing opening 15, the remaining amount of the chemical solution can be seen from this opening 15.

The storage batteries 1 and 2 in the hoseless spray A configured as described above are constantly charged by a charging device (not shown). When the micro compressor 9 is driven by the storage battery 12, the micro compressor 9 sends compressed air into the pressure storage tank 7.

The compressed air in the pressure accumulator tank 7 enters the chemical liquid container 1 via the pressure regulator 3 and increases the pressure inside the chemical liquid container 1. When the on-off valve 6 of the hoseless sprayer 8 is opened when the pressure inside the drug solution container 1 is high, the drug solution is injected from a catheter (not shown) attached to the tip of the injection part 4.

As soon as the pressure in the accumulator tank 7 drops, the micro compressor 9 starts operating. Therefore, when the doctor sprays, the micro compressor 9 is immediately operated to increase the pressure in the pressure storage tank 7 by the storage battery 12.

The doctor places his index finger lightly on the opening/closing button 5, holds Hoseless Spray A like he is holding a pistol, and brings the catheter of Hoseless Spray A close to the patient's affected area. While spraying, the doctor uses the housing 1 in the hoseless sprayer A to check whether there is a medicine in the medicine container 1.
It can be visually recognized from the opening 15 of 4.

When the doctor's treatment is over, the hoseless sprayer A is placed on a charging device (not shown) to charge the storage battery 12 and send compressed air into the pressure storage tank 7 by the micro compressor 9.

When the pressure inside the pressure storage tank 7 exceeds the specified level, the micro-
Since the torque of the motor (not shown) of the compressor 9 increases, this torque is detected and the rotation of the motor is stopped. Then, when the pressure inside the pressure storage tank 7 decreases, the motor is rotated again by a detection signal from a sensor that detects the pressure of the valve 10.

If a doctor sprays the affected area intermittently, they can do so in small increments, like pulling the trigger of a pistol.

Further, even though the doctor has the hoseless sprayer A, the pressure in the pressure accumulator tank 7 immediately returns to the specified value.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. Various design changes can be made without departing from the scope of the invention as set forth in the claims.

For example, a pressure adjustment section including the open/close button 5, a coupler 8 that connects the pressure adjustment section and the pressure accumulation tank 7, and a pressure accumulation tank 7.
The structure relating to the connecting portion between the micro compressor 9 and the micro compressor 9 can be modified in various ways using well-known techniques.

〔Effect of the invention〕

According to the present invention, everything necessary except for the injection part is built into the housing, and the opening/closing button is placed at the index finger position, so a commercially available charging device can be used, and it is also a small and easy-to-use hoseless battery. It's a spray.

Furthermore, since the housing is provided with an opening, there is no need to continue medical treatment without noticing that there is no medicinal solution.

According to the present invention, the pressure accumulator tank and the micro compressor are integrated with each other via the valve, so the structure is simple and leakage of compressed air is reduced.

In particular, when spraying is performed intermittently, compressed air is stored in the pressure storage tank even when spraying is not performed, making medical treatment easier.
