Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a medical solution dropping device, and by attaching it to, for example, a dental treatment unit,
This makes it easy to obtain a gargle solution with a predetermined concentration.

[Conventional techniques and their problems] Traditionally, gargling during dental treatment has been used to make the patient feel refreshed, to make it easier for the patient to receive treatment in a stable mood, and to suppress bad breath so that the surgeon can provide treatment to the patient. To make it easier to apply, we use a gargle solution made by dissolving gargle solution in tap water. This gargle solution is a mixture of tap water and gargle solution at a ratio of around 100:1. To prepare this gargle solution, the operator or an assistant adds gargle solution each time tap water is poured into the pot. Since the gargle was being dripped, it was difficult to obtain a gargle solution with a constant concentration.

This idea was created to solve these problems, so for example, it is possible to adjust a predetermined concentration of gargle solution by dropping a certain amount of gargle solution into the pot without bothering the operator or assistant. The purpose of the present invention is to provide a chemical liquid dropping device that can perform the following operations.

[Means for solving the problem] This invention provides a water outlet at the bottom, connects the water chamber for supplying running water and the pressure application chamber with a water conduit pipe, forms a chemical solution dripping port at the bottom, and connects the pressure chamber to the pressure chamber. The solution was to connect the gas phase portion of the chemical chamber to be engraved and the air chamber through an air guide pipe, and to connect the pressure applying chamber and the air chamber through a flexible valve.

[Function] In the chemical solution dripping device of this invention, when water flows into the water flow chamber, water pressure is applied inside the water flow chamber because the diameter of the water outlet is smaller than that of the water flow chamber.
The pressure in the pressure applying chamber connected to the water flow chamber by a water conduit increases.

This applies pressure to the flexible valve that separates the pressure applying chamber and the air chamber, and the flexible valve deforms to reduce the volume of the air chamber.As a result, the air pushed out of the air chamber The liquid medicine is quantitatively dripped from the liquid medicine dripping port formed at the bottom of the liquid medicine chamber by pushing the liquid surface of the liquid medicine stored in the liquid medicine chamber through the air guide pipe.

[Example] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 shows an embodiment of the drug solution dropping device of the present invention attached to a dental treatment unit, and reference numeral 1 in FIG. 1 indicates the drug solution dropping device of the present invention.

The drug solution dripping device 1 is attached to the water supply port 31 of the dental treatment unit 30, and each time water is supplied from the water supply port 31 into the pot 32 used by the patient when gargling, the gargle solution is dripped at a constant concentration. Gargling solution is now available.

As shown in FIG. 2, this chemical liquid dropping device 1 has the following features:
It is roughly constructed by connecting a pressure applying chamber connected to a water flow chamber by a water conduit, and an air chamber connected to a chemical solution chamber by an air conduit through a flexible valve, as shown in Fig. 2. Reference numeral 11 is a chemical liquid chamber.

This medicinal solution chamber 11 is filled with a gargling solution L. A drug solution dripping port 12 is formed at the bottom of the drug solution chamber 11 to drip the gargling solution L into the pot 32.
It is hermetically sealed by a lid body 13 with a ring interposed therebetween. In addition, an air guide pipe 14 is provided on the upper side wall of the chemical liquid chamber 11.
is formed, and the gargling medicine liquid L in the medicine liquid chamber 11
The gas phase portion which is not filled is connected to the air chamber 15 provided on the side of the chemical liquid chamber 11.

The air chamber 15 has a trapezoidal shape,
The bottom part with a small area is connected to the air guide pipe 14, and the bottom part with a large area is opened and is connected to the flexible valve 16.
It faces the pressure applying chamber 17 via. The pressure applying chamber 17 has the same shape as the air chamber 15, and is connected to the water flow chamber 19 by a water conduit 18 at a bottom portion having a small area.

A water outlet 20 for supplying running water is formed at the bottom of the running water chamber 19. The diameter of the water outlet 20 is smaller than the diameter of the water flow chamber 19 so that when water flows into the water flow chamber 19, most of the water stays in the water flow chamber 19. The upper opening of the water chamber 19 is connected to a water faucet or a water inlet of a dental treatment unit via an O-ring (not shown).

Using such a chemical liquid dropping device 1, the chemical liquid chamber 11 is
In order to drip the gargle solution L filled in the mouthwash into the spout 32 installed in the dental treatment unit 30, first, as shown in FIG. When the water supply port 31 is opened and the water flow chamber 19 is filled with water, the water conduit 18
and the pressure applying chamber 17 is filled with water,
Water is supplied into the pot 32 from the water outlet 20.
At this time, since the diameter of the water outlet 20 is set smaller than that of the water flow chamber 19, most of the water that has flowed into the water flow port 19 remains within the water flow chamber 19.
The pressure inside the water flow chamber 19 increases. Along with this, pressure is applied to the flexible valve 16 stretched over the large area bottom of the pressure applying chamber 17, and the flexible valve 16 is deformed by this pressure so as to reduce the volume of the air chamber 15. do. Due to this deformation of the flexible valve 16,
The air pushed out from the air chamber 15 is transferred to the air guide pipe 14.
It passes through the inside and reaches the gas phase of the drug solution chamber 11, where it pushes the interface of the gargling solution L downward. Gargle liquid L is
Due to this pressure, the chemical liquid is dripped into the pot 32 from the chemical liquid dripping port 12 formed on the bottom surface of the chemical liquid chamber 11 .

When the pot 32 is filled with a certain amount of gargling liquid L and water in this way, the water supply from the water supply port 31 of the unit 30 is stopped due to its weight, so the dripping of the gargling liquid L is completed, and a certain amount of gargling liquid L can be dripped into the pot 32 and diluted with water supplied from the water outlet 20 to adjust a predetermined concentration of gargle fluid.

FIG. 4 shows another embodiment of the chemical liquid dropping device of the present invention, and the difference between this chemical liquid dropping device and the one shown in FIG. 3 is that the dripping amount adjustment screw 21
This is where it was installed. One end of the dripping amount adjusting screw 21, to which the knob 21a is attached, protrudes from the outer wall of the water flow chamber 19, and the other end is attached to the water conduit 18.
It penetrates through the inside, reaches the pressure applying chamber 17, and is attached to the flexible valve 16 inside the pressure applying chamber 17. By rotating the knob 21a, the degree of penetration of the dripping amount adjusting screw 21 into the pressure applying chamber 17 can be changed, and the flexible valve 16 attached to the dripping amount adjusting screw 21 can be changed. , the volume ratio between the air chamber 15 and the pressure applying chamber 17 can be changed. When the degree of penetration of the dripping amount adjusting screw 21 into the pressure applying chamber 17 is increased, the flexible valve 16 is deformed to reduce the volume of the air chamber 15, and the volume of the pressure applying chamber 17 is increased, so that the water flow is reduced. The degree of deformation of the flexible valve 16 due to the water pressure in the chamber 19 is reduced, and the pressure that presses the interface of the gargling liquid L in the liquid medicine chamber 11 can be set small. Conversely, if the degree of penetration of the dripping amount adjustment screw 21 into the pressure applying chamber 17 is reduced, the flexible valve 16 is deformed to reduce the volume of the pressure applying chamber 17, so that the volume of the air chamber 15 is reduced. becomes larger, the degree of deformation of the flexible valve 16 due to the water pressure in the water flow chamber 19 becomes larger, and the amount of dripping of the gargling liquid L in the liquid medicine chamber 11 can be increased.

In this way, when the knob portion 21a is rotated, the flexible valve 16 separating the pressure applying chamber 17 and the air chamber 15 can be deformed in advance, so that when the flexible valve 16 is supplied with water, the flexible valve 16 can be deformed in advance. The degree of deformation due to water pressure can be freely changed, and the chemical liquid chamber 11
By changing the pressure applied to the interface of the gargling liquid inside, the amount of the gargling liquid dropped can be adjusted.

[Effects of the invention] As explained above, the chemical solution dripping device of the invention has a water outlet at the bottom and connects the water flow chamber for supplying running water and the pressure application chamber by a water conduit pipe.
A chemical liquid dripping port is formed at the bottom, and the gas phase part of the chemical liquid chamber for storing the chemical liquid is connected to the air chamber by an air conduit, and the pressure applying chamber and the air chamber are connected via a flexible valve. Therefore, each time water flows into the water flow chamber, the water pressure in the water flow chamber increases and the flexible valve deforms, so that a certain amount of the chemical solution can be dropped and diluted to a constant concentration.

Furthermore, since the degree of deformation of the flexible valve can be changed using the dripping amount adjusting screw, it is possible to change the dripping amount of the medicinal solution and dilute the medicinal solution to a desired concentration. By attaching the device to a container, etc., it is possible to easily obtain a gargle solution of a predetermined concentration.
