Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an inhaler, and is particularly suitable for eliminating vomiting and blood in the trachea, oral cavity or nasal cavity of a victim, erecting the penis, or ejecting when a catheter is occluded by a foreign substance sucked. Regarding the sucker

[0002]

2. Description of the Related Art A conventional method for removing foreign matter such as blood and vomiting in the tracheal cavity or nasal cavity of a victim is to compress a rubber ball or bellows with a manual or foot-operated pump. Suction performed using the restoring force of the elastic body, suction performed by driving the piston with a battery,
Examples include a suction device that uses an ejector that uses oxygen gas. If the catheter is clogged with foreign matter to be removed, remove the catheter from the suction container and push it out with exhalation.
If that is not possible, I am using a new catheter.

Further, the conventional methods for erecting the penis include taking an internal drug, injecting a vasodilator with a syringe, a method called a prosthesis method for embedding a silicone rod in the penis, and manual suction / exhaustion. There is a method using a container.

[0004]

The suction / exhaust device using a manual or foot-operated pump has a weak suction force of at most -300 mmHg, and the suction force is weak, so that the suction catheter is apt to be clogged with suctioned substances. . If it becomes clogged, remove the catheter from the suction container and exhale, but if this is not possible, a new catheter must be used.

Although the battery-powered suction and discharge device has a suction force of up to about -600 mmHg, it has a drawback that it is difficult to carry when used in the field by the emergency department of the fire department because the main body weight is heavy (4 Kg to 8 Kg) and bulky. .

[0006] The ejector using an ejector using oxygen gas has a drawback that it is not suitable for a site because it uses a heavy oxygen cylinder for suction.

[0007] In the case of penile erection, there is no definitive oral medication at present, and there is a problem of side effects. Since the injection of the vasodilator by a syringe uses a needle to inject the drug into the penis, there are problems of pain and risk of AIDS.

According to the prosthesis method, water is poured into a pen made of silicone embedded in the penis to create an erection state before sexual activity, so that a cold feeling is given to a woman and, in addition, a surgery for embedding a silicone stick is required. Is.

In the case of a manual suction / exhaust device, the suction force is at most-
Weakness of about 300 mmHg and insufficient erection force,
In addition, the piston is operated to generate the vacuum, but there is a problem that this suction takes time.

It is an object of the present invention to provide a suction / exhaust device which has a strong suction force, can be sucked in a short time, is easy to operate, and is safe, and therefore can be applied to each of the above cases.

[0021]

[Function] The small high-pressure gas container is screwed into the mounting port of the gas supply unit to be mounted. Next, when the gas discharge lever of the gas supplier is pushed, the gas flows from the small high-pressure gas container into the vacuum generator, the flow velocity is increased by the orifice, and then the gas is discharged to the outside through the discharge port. When passing through this orifice, the inside of the passage opened to this side surface becomes negative pressure, so that the air in the suction container flows into this passage and is sucked by the vacuum generator.
Therefore, the inside of the suction container is in a vacuum state, and the foreign matter outside the suction container is sucked through the suction container through the inlet, and the suction force is not directly applied to the foreign matter inserted through the inlet into the suction container. To work.

The suction container has a main body and a lid detachably attached to the main body, the lid is provided with the connection port (32) and the inlet, and an elastic pipe portion has a discharge port at a base end thereof. When the discharge port of the suction catheter having the suction port at its end is selectively connectable to the inlet and the discharge port of the vacuum generator, the discharge port of the suction catheter is guided to the inlet of the suction container. If the suction catheter is tied and the suction catheter is inserted into the tracheal cavity or nasal cavity of the victim, the vomiting substance and blood accumulated in them can be sucked into the suction container.

The size of the suction container is selected according to the size of the suction amount. Foreign substances collected in the suction container are removed from the lid and discarded at any time. Further, when the gas is sent by connecting the discharge port of the suction catheter filled with the foreign substance to the discharge port of the vacuum generator, the foreign substance in the suction catheter can be discharged by the gas discharge pressure.

The inlet is located at the upper end of a short pipe portion that vertically penetrates the top of the lid, the connection port is bored in the side wall portion, and the outlet at the lower end of the short pipe portion is on the axis of the connection port. If it is located below, the lid can be easily molded, and the sucked foreign matter falls directly into the main body without being pulled toward the connection port, and the suction catheter fits into the short tube portion. It is attached to the lid and pulled out to be removed from the lid.

When the connection port and the inlet are formed in the side wall of the lid and the connection port and the inlet are partitioned by the short-circuit prevention wall, the foreign matter jumping through the suction catheter into the lid is prevented. It hits the wall and falls into the body, preventing it from going directly to the connection.

The connecting port and the opening open on the side surface of the lid,
When communicating with separate conduits, each of which is open on the underside of the lid at a distance from each other, the foreign matter that escapes from there through the suction catheter is guided to the body by the passage of the lid. The lid does not scatter on the inner surface and the lid can be easily manufactured.

The small high-pressure gas container and the suction container attached to the gas supply device are a pedestal for accommodating the lower end of the small high-pressure gas container, and a pedestal for fitting the lower end of the suction container. With a fixture with a through-hole having parallel axes,
If they are erected parallel to each other, the small high-pressure gas container and the suction container can be placed upright on a table or the like, which is convenient for work.

When the suction container has elasticity and the entrance has a diameter that allows the penis to move in and out, the penis is inserted into the suction container from the entrance, and the entrance is brought into close contact with the lower abdomen. When gas is sent from the supply device, the inside of the suction container becomes a vacuum, and the suction force acts on the penis, so that the blood vessel swells and promotes the inflow of blood to erect it.

In the case of an intake / exhaust device having a switching valve,
When pressure gas is sent from the gas supply device while keeping the switching valve in the operating position, the gas flows through the orifice of the vacuum generator, the discharge port through the inlet port of the switching valve, and the discharge port to the outside. Since a vacuum is generated by this gas flow in the vacuum port of the vacuum generator, the breathing port draws in outside air, foreign matter, etc., and pulls it through the delivery port to the vacuum port. Outside air, foreign matter, and the like are conveyed to the flow of pressure gas here, and are discharged to the outside from the discharge port of the switching valve.

When the hose is clogged with foreign matter or the like, the switching valve is switched to the original position. Then, the pressure gas flows from the inlet port of the switching valve to the breathing port and flows out. Further, the atmosphere is sucked into the vacuum port through the suction port of the switching valve, and this atmosphere also flows out to the outside together with the pressure gas. Therefore, both the pressure gas and the atmosphere can be used as the blowing gas.

The outer end of the discharge pipe portion 24 at the other end of the vacuum generator 2 is opened as a discharge port 25. Further, the vacuum generator 2 is provided with an orifice 26 in the middle, and one end of a passage 27 whose other end communicates with the outside is opened on the side surface of the orifice.

The suction container 3 is attached to the vacuum generator 2 with its connection port 32 communicating with the passage 27 of the vacuum generator 2 via the connection pipe portion 31. The suction container 3 is also provided with a foreign material inlet 33. In the illustrated example, the outer end portion of the connection pipe portion 31 is screwed to the side surface of the vacuum generator 2 via an O-ring 34 to connect the passage 27 and the connection port 32.

In this suction / exhaust device, a small high-pressure gas container 11 is attached to the gas supply device 1 and opened, and when the lever 16 is pushed in, the depressurized gas flows into the vacuum generator 2 from the discharge port 17 and the orifice 26. It flows through the discharge port 25 at the lower end into the atmosphere. When flowing through the orifice 26, the inside of the passage 27 has a negative pressure, so that the air in the suction container 3 is sucked out, and a suction force is generated in the suction container 3. Therefore, foreign matter outside the suction container 3 is sucked into the suction container 3, and the suction force directly acts on the foreign matter loaded in the suction container 3.

The suction container 3 has a main body 35 and a lid 36 which is detachable from the main body. The lid 36 is provided with the above-described connection port 32 and inlet 33. And the elastic tube portion 41

The inlet 33 is located at the upper end of a short pipe portion 38 which vertically penetrates the top portion 37 of the lid 36, the connection port 32 is bored in the side wall portion 39, and the outlet 33 ′ at the lower end of the short pipe portion 38 is formed. It is located below the axis of the connection port 32. In this way, the lid 36 can be easily molded, and the sucked foreign matter will not be sucked into the connection port 32.
Falls directly into the body 35 without being pulled in any direction,
The suction catheter 4 is fitted into the short tube portion 38, attached to the lid 36, and pulled to be removed from the lid 36.

In FIG. 3, the connection port 32 and the inlet 33 are covered with a lid 36.
The side wall portion 39 of the
Is partitioned by a short circuit prevention wall 51. By doing so, the foreign matter coming through the suction catheter 4 and jumping out into the lid 36 hits the short-circuit prevention wall 51 and falls into the main body 35, so that the vacuum generator directly passes from the connection port 32 through the connection pipe portion 31. It prevents you from going to 2.

In FIG. 4, the connection port 32 and the inlet 33 are covered with a lid 36.
Open to the side surface 52 of the lid 36, and communicate with respective separate conduits 54 and 55 that open to the lower surface 53 of the lid 36 at a distance from each other. In this way, the foreign matter that has passed through the suction catheter 4 and entered from the discharge port 42 into the inlet 33 is ejected toward the bottom of the main body 35 of the suction container 3 by the guide passage 55, and only the air passes through the guide passage 54 and the vacuum generator. Since it is sucked by 2, the foreign matter does not scatter and adhere to the inner surface of the lid 36.

As shown in FIG. 1, the small high-pressure gas container 11 and the suction container 3 attached to the gas supplier 1 are provided with a pedestal 61 for accommodating the lower end of the small high-pressure gas container 11 and a lower end of the suction container 3. The fixtures 6 provided with the through holes 62 for fitting and having an axis parallel to the pedestal portion 61 are erected parallel to each other. By doing so, the small high-pressure gas container 11 and the suction container 3 can be placed upright on a desk or the like, which is convenient for work.

In FIG. 5, the suction container 3 has elasticity, and the inlet 33 has a diameter that allows the penis to move in and out. By doing this, the penis is inserted into the suction container 3 through the inlet 33, the rim of the inlet 33 is brought into close contact with the lower abdomen, and when gas is sent from the gas supply device 1, the suction container 3 becomes a vacuum and is sucked into the penis. The force causes the blood vessels to swell, accelerating the inflow of blood and erection.

6 and 7 show an example of the intake / exhaust device having the switching valve 7. FIG. 6 shows the original state and FIG. 7 shows the operating state.
The original state and the operating state here are relative relationships, and it does not matter even if the original state is expressed as the operating state and the operating state as the original state. FIG. 8 is a cross-sectional view of another example of the vacuum generator 2, in which a check valve 29 is installed in the vacuum port 28.

The switching valve 7 has five ports that are opened and closed by the movement of the valve body 71. The suction port 72 is opened to the atmosphere, and is disconnected from the delivery port 73 by the valve body 71. The delivery port 73 communicates with the vacuum port 28.
On the other hand, the inlet port 74 communicates with the discharge port 25 of the vacuum generator 2 and, in many ways, the valve port 71 selectively communicates with the breathing port 75 and the discharge port 76. This operation is such that when the suction port 72 is in communication with the delivery port 73, the suction port 72 is in communication with the breathing port 75 in the original state, and the suction port 72 is blocked from the delivery port 73.
It is designed to communicate with 6. 77 is a pin lever, 7
8 is a conduit.

When the pin lever 77 is kept in its original state and gas is supplied from the gas supply gas 1, the gas flows to the vacuum generator 2 and a vacuum is generated in the vacuum port 28. For this reason, the atmosphere is sucked into the vacuum generator 2 through the suction port 72 and the discharge port 73 of the switching valve 7, and the discharge port 25 together with the pressure gas.
Through the conduit 78 to the inlet port 74 of the switching valve 7 and further through the breathing port 75 to be ejected from the catheter 4'to the outside. Therefore, if the catheter 4'is clogged with foreign matter, the foreign matter is ejected out of the catheter by the ejected gas.

When the pin lever 77 is returned to the operating position, the inhalation port 72 is closed and the breathing port 75 is opened.
3, the inlet port 74 communicates with the outlet port 76. Therefore, a suction force acts on the open end of the catheter 4 ', and foreign matter is sucked into it. The sucked foreign matter goes to the outside together with the pressure gas through the breathing and sending ports 72 and 73 of the switching valve 7, the vacuum generator 2, and the sending and discharging ports 74 and 76 of the switching valve 7. Is discharged.
