Description

[Detailed description of the invention] (Industrial application field) This invention is used to inhale oxygen and other medical gases (hereinafter abbreviated as oxygen) into the body for the purpose of diagnosing or treating various physical conditions. The present invention relates to a humidifying device for oxygen inhalation to provide humidity to the air.

(Prior art) The gas used for conventional oxygen inhalation is not necessarily pure oxygen, but also includes oxygen, helium, carbon dioxide, nitrogen, carbon monoxide, helium and carbon dioxide, and laughing gas (nitrous oxide). and those to which Zenon gas, etc. are added are used.

However, all such gases are dry gases, and when inhaled, moisture is removed from the inner walls of the air passages of the nose, mouth, throat, bronchi, etc., causing not only discomfort to the patient but also sputum (secretions). There is a problem in that because it is difficult to expectorate the air, it increases the resistance of respiratory airflow and aggravates the symptoms.

Therefore, currently widely used humidification methods include (a) a bubbling method in which the inhaled air is passed through the water contained inside the bottle, and (b) a suction effect in which the inhaled air is ejected through small holes. The water is sucked up and sprayed,
(c) A method that uses gas pressure to generate ultrasonic waves to generate a mist of water in the aquarium, (d) An electric method that uses electric power to generate ultrasonic waves and vibrates the water to encourage water vapor to dissipate. This is the current situation. As mentioned above, all of these methods require a water tank.

However, the water tank method has the following serious drawbacks.

(1) The water level in the tank must be kept within the specified line at all times.

(2) The tank must be held vertically at all times.

(3) If the water tank falls over, there is a risk that liquid water may enter the patient's nose, trachea, etc. while inhaling.

(Please note that great care must be taken when using it while walking or traveling in a wheelchair, vehicle, or other means of transportation.) (4) It takes a lot of time to maintain the cleanliness inside the aquarium.

The atomizing method consumes a large amount of gas, the gas-driven ultrasonic method consumes a large amount of gas, and the electric ultrasonic method requires electric power and is large in size.

(Problems that the invention aims to solve) In order to solve the above-mentioned drawbacks, this invention not only makes the humidifying device lighter and smaller, but also double-layers the humidifying material at the top and bottom so that it can humidify for a long time. This prevents water from overflowing even if the humidifier falls over, eliminates the troublesome cleaning required with conventional humidifiers, and allows the inside of the flowmeter to be seen.

(Means for Solving the Problems) In order to solve all the above-mentioned problems, the oxygen inhalation humidifier of this invention has a humidifier 1 equipped with a transparent suction cylinder 5 and a lid 6 for closing. Inside the suction cylinder 5, water 12 is injected into the lower part, and an upper humidifying material 7 and a lower humidifying material 9, such as an open cell material, which absorb moisture above the water 12, are brought into contact with each other. It is housed in two stages, upper and lower, through a perforated plate 8 that allows gas to easily pass through without causing any gas to pass through. Insert the pipe 3 vertically to the water surface,
A humidifying oxygen outlet 17 is installed in a part of the lid body 6,
We aim to achieve the above objectives.

(Embodiment) Next, an embodiment of this invention will be described with reference to the drawings.The humidifying device 1 has a cylindrical shape, etc., which is installed between an oxygen supply side and an oxygen intake side, and is made entirely of transparent plastic. It consists of a suction cylinder 5 and a closing lid 6 that is screwed onto the upper part. A vertical flow meter 2 is installed upright on the top of the lid 6 of the humidifier 1. An oxygen blowing pipe 3 is vertically installed in the flow meter 2 and is connected to the bottom thereof. Next, the suction cylinder 5
, an upper humidifying material 7 such as an open cell material that absorbs moisture is stored in the upper part, and various perforated plates 8 are interposed in the lower part, and a lower humidifying material 9 is placed in the upper and lower parts.
Install a large amount in stages. A perforated plate 10 or the like may be interposed below the lower humidifying material 9. Reference numeral 11 denotes a ring-shaped support shelf provided on the inner surface of the suction cylinder 5 that supports the perforated plate 10 and the like. Furthermore, water 12 is previously injected into the inner bottom of the suction cylinder 5 to a predetermined depth. Reference numeral 4 denotes a stop plate which is detachably installed at the lower end of the oxygen blowing pipe 3 and serves to prevent the upper and lower humidifiers 7, 9, perforated plates 8, 10, etc. from falling. In addition, the flowmeter 2 includes:
It has an opening window through which the inside can be seen, and has a float 15 inside and a scale 16 on the surface.
Next, a humidified oxygen outlet 17 is installed at a predetermined position on the outer periphery of the lid 6, and the humidified oxygen outlet 17 is connected to a tube attached to a device suitable for human inhalation of humidified oxygen, such as a patient mask or a cannula. The shape makes it easy to put on and take off. An oxygen supply pipe 13 provided with a flow rate regulating valve 14 is connected to the lower outer periphery of the flow meter 2 .

(Function) This device has the above-mentioned configuration, and to explain how to use it now, it is used by connecting a mask or cannula for oxygen inhalation to the humidifying oxygen outlet 17 at the patient's nose, mouth, etc. However, when the transparent suction cylinder 5 is pulled down from the lid 6 by unscrewing, the upper humidifying material 7, the perforated plate 8 and the lower humidifying material 9 in the middle are exposed to the oxygen in the center. The suction cylinder 5 is removed while attached to the blow pipe, and a required amount of water 12 is injected into its interior, if necessary, to the extent that the water level reaches the ring-shaped support shelf 11. In addition, when using it for the first time, remove the stop plate 4 located below the oxygen blowing pipe 3, and remove the lower humidifying material 9, perforated plate 8, and upper humidifying material 7 in sequence. The lower humidifying material 9 removes water that becomes free droplets after being sufficiently impregnated with water, and the upper humidifying material 7 removes as many water droplets as can be shaken off by normal human power after being sufficiently impregnated with water. After removing it, it is assembled in the opposite manner to the above, and the suction cylinder 5 containing the water 12 is screwed on. Thereafter, medical oxygen at a flow rate adjusted by operating the flow rate control valve 14 is supplied through the oxygen supply pipe 13 by floating the float 15 from below as shown by the arrow and checking and instructing the flow rate using the scale 16.
The oxygen is automatically adjusted and humidified while passing through the outer periphery of the inside of the oxygen blowing pipe 3, submerging the water 12, and passing through the lower humidifying material 9 and the upper humidifying material 7, and is sent out from the upper humidified oxygen outlet 17. and used.

(Effects of the device) This device is configured as described above, so it reliably humidifies the oxygen inhaled into the body and can humidify the body for a long time without causing discomfort to the nose, mouth, throat, trachea, etc. This is an unprecedented effect, and as long as the flow rate is adjusted with the flow control valve in a vertical position at the beginning of use, the flow rate will not change even due to vibrations or tilting during subsequent use, and it is completely different from conventional methods. It has the effect of allowing you to use it with confidence without worrying about water leaking or overflowing. Since the suction cylinder of the humidifying device is made of a transparent material, it is easy to see through the lack of water inside the humidifying material, and when the lower humidifying material becomes insufficiently hydrated, the color becomes pale and the water is easily absorbed. It has the effect of determining when to replenish supplies. Since the humidifying material is divided into upper and lower parts with perforated plates, it is easy to replace and install.Moreover, the lower humidifying material promotes the evaporation of water injected into the bottom of the suction cylinder and retains sufficient water. In addition to the effect of shielding the rise in free moisture in the perforated plate, it also has the excellent effect of acting as a breakwater to prevent water droplets from entering the humidifying oxygen outlet due to an excessive increase in the moisture content of the upper humidifying material. be. Furthermore, if the upper and lower humidifying materials inside become contaminated for some reason, the suction cylinder can be separated by simply unscrewing, and the interior can be easily cleaned and the humidifying materials can be easily washed.

Furthermore, the internal float installed on the top of the lid body and the scale on the surface are visible, and the meter allows you to visually check the flow rate adjusted by the position of the scale as the float rises. .
