Description

  The present invention relates to a particle supply apparatus.

  Conventionally, when a drug is administered to a patient, there is a method of administering via the nose in addition to a method of taking it from the mouth or a method of injection (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 07-323086

  However, in the conventional example in which a medicine is administered via the nose, when a certain amount of a medicine composed of gas is administered to a patient, the medicine drifting around the nose is removed without being administered to the patient. There is a problem that it is difficult. In addition, when a medicine that is not administered to a patient floats in the air, there remains a problem that a medical institution worker such as a doctor around the patient may inhale.

  The above problem is not limited to gas, but also occurs in general for particles such as odor, liquid, and powder.

  In other words, in the above conventional example, when supplying particles such as gas, odor, liquid, powder, etc. via the human nose, there is a problem that more than the necessary amount of particles cannot be removed, and the human nose. Therefore, there is a problem that particles that have not entered the human body often float in the air.

  In the present invention, when supplying particles such as gas, odor, liquid, powder, etc. via a human nose, particles exceeding a necessary amount can be removed, and particles that have not entered the human body from the human nose. An object of the present invention is to provide a particle supply device in which air is less likely to float in the air.

An odor supply apparatus for MRI examination for examining a human reaction according to the odor of the present invention includes a supply pipe that forms a path for supplying the odor, which is a reaction test sample, to the position of the person's nose, and the odor through the supply pipe. An optical fiber that guides ultraviolet light that irradiates and erases the odor around the nose, and a discharge tube that discharges the odor present at the position of the human nose. It is characterized by that .

  According to the present invention, when supplying particles such as gas, odor, liquid, powder, etc. via the human nose, it is possible to remove more particles than necessary, and it does not enter the human body from the human nose. There is an effect that the particles are less likely to float in the air.

It is sectional drawing which shows the odor supply apparatus SP1 which is Example 1 of this invention. It is sectional drawing seen from the II-II line | wire of FIG. It is sectional drawing which shows the odor supply apparatus SP2 which is Example 2 of this invention. It is sectional drawing seen from the IV-IV line of FIG. It is a figure which shows odor supply apparatus SP3 which shows Example 3 of this invention. It is sectional drawing seen from the VI-VI line of FIG.

  The mode for carrying out the invention is the following embodiment.

  FIG. 1 is a cross-sectional view showing an odor supply apparatus SP1 that is Embodiment 1 of the present invention.

  2 is a cross-sectional view taken along line II-II in FIG.

  The odor supply device SP1 includes an optical fiber 10, a concave lens 11, an inner tube 20, and an outer tube 30. The optical fiber 10 is an optical path that guides light to the vicinity of a human nose N. A light source (not shown) is provided, and this light source is a light source that supplies light to the optical fiber 10. The light is a so-called photocatalyst, and ultraviolet rays are used. In addition, you may make it use visible light instead of an ultraviolet-ray.

  The inner tube 20 is a supply tube that forms a path for supplying a predetermined odor to the position of a person's nose N. The outer tube 30 is a discharge tube that discharges air when it exists at the position of the human nose N.

  Further, the nose N and the outer tube 30 are bonded to each other so that the gas in the inner tube 20 and the gas in the outer tube 30 do not leak outside. As long as the nose N and the outer tube 30 are in close contact with each other and the gas in the inner tube 20 and the gas in the outer tube 30 do not leak to the outside, any means can be used for bonding the nose N and the outer tube 30. It may be a simple means.

  Next, the operation of the above embodiment will be described.

  Before supplying the smell to the person's nose N, the following preparations are made. That is, the end of the optical fiber 10 (the end opposite to the nose N) is connected to a light source (not shown). The end of the inner tube 20 (the end opposite to the nose N) is connected to an odor generating source (not shown), and an opening for introducing air is provided in a part of the inner tube 20. Further, the end of the outer tube 30 (the end opposite to the nose N) is connected to a suction pump (not shown).

  And when supplying an odor to a person's nose N, after the said preparation is prepared, suction is started with the pump for suction. As a result, a predetermined odor reaches the person's nose N from the odor source via the inner tube 20, and the person feels the odor. After supplying the odor for a predetermined time, the door (not shown) of the odor source is closed and only air is supplied to the human nose N. Here, a light source (not shown) generates ultraviolet rays and reaches the concave lens 11 via the optical fiber 10. The concave lens 11 diffuses ultraviolet rays, irradiates around the nostrils N1 and N2, decomposes odor elements (odor molecules) existing near the nostrils N1 and N2, and erases the odor. To do. Ultraviolet rays serve as a photocatalyst to eliminate odors, that is, deodorize.

  The odor supply device SP1 is a device used when a person smells a specific scent. For example, it is used when a person smells a specific smell and examines the reaction. When examining the reaction, MRI may be used. In this case, if the inner tube 20 and the outer tube 30 are made nonmagnetic, the MRI is not adversely affected.

  Moreover, not only using the odor supply device SP1 for supplying odor to the nose but also when administering a medicine to a patient. For example, an analgesic such as a headache drug, a muscle relaxant, a drug (medicine) such as a sleeping pill can be administered. In this case, particles (chemicals) such as liquid and powder may be used in addition to gas.

  In the first embodiment, a plurality of optical fibers 10 may be provided. The optical fiber 10 may be bonded to the inner tube 20 or may be bonded to the outer tube 30.

  In the first embodiment, the concave lens 11 may be deleted. Alternatively, the concave lens 11 may be deleted and a concave lens shape may be formed at the tip of the optical fiber 10.

  In the first embodiment, the inhalation is supplied from the inner tube 20 to the nose N, and the inhalation is discharged through the outer tube 30. On the contrary, the odor is discharged from the outer tube 30 to the nose N. Alternatively, inhalation may be supplied and smelled via the inner pipe 20 to discharge exhaled air.

  Furthermore, in Example 1, although the cross section of the inner tube | pipe 20 and the outer tube | pipe 30 is substantially elliptical shape, you may make it shapes other than elliptical shape.

  In addition, if a lavender etc. are used as said smell, a patient will relax.

  FIG. 3 is a cross-sectional view showing an odor supply apparatus SP2 that is Embodiment 2 of the present invention.

  4 is a cross-sectional view taken along line IV-IV in FIG.

  The odor supply device SP2 is a device in which a sheet 40 and titanium dioxide (TiO2) 50 are added to the odor supply device SP1.

  The transparent sheet 40 has a thickness of, for example, 10 μm to several mm, and is fixed to the end of the outer tube 30 although omitted in FIG. 3.

  Titanium dioxide 50 is a photocatalyst and is provided in the vicinity of the human nose. Although ultraviolet rays alone have an effect of erasing odors, when the titanium dioxide 50 is irradiated with light, the effect of the photocatalyst is promoted. Note that the titanium dioxide 50 is applied to the transparent sheet 40 and is provided at a position where light passing through the optical fiber 10, the concave lens 11, and the transparent sheet 40 is irradiated. If the titanium dioxide 50 is applied to the optical fiber 10 side of the transparent sheet 40, the transparent sheet 40 does not need to be transparent.

  The operation of the second embodiment is basically the same as that of the first embodiment, but the deodorizing operation is slightly different. That is, in Example 2, when the titanium dioxide 50 is irradiated with ultraviolet rays, electrons are ejected from the surface of the titanium dioxide 50, and the holes from which the electrons have escaped are called holes and have a positive charge. . The holes have a strong oxidizing power and take electrons from OH- (hydroxide ions) and the like existing in water. The OH− from which the electrons have been removed becomes OH radicals that are in a very unstable state. Since this OH radical has a strong oxidizing power, it takes an electron from an organic substance existing nearby and tries to stabilize itself. Then, the organic substance from which the electrons have been deprived breaks the bonds, and eventually becomes carbon dioxide or water.

  Since one of the organic substances has an odor, the odor molecule is broken in its bond to carbon dioxide or water. Also, malodors such as acetaldehyde, ammonia, hydrogen sulfide, etc. are decomposed.

  As described above, in Example 2, since titanium dioxide 50 is provided, the effect of the photocatalyst is promoted, the deodorization is performed in a shorter time than Example 1, and the amount of deodorization is larger than that in Example 1. .

  Instead of the titanium dioxide 50, another photocatalyst may be provided.

  FIG. 5 is a diagram showing an odor supply device SP3 showing Embodiment 3 of the present invention.

  6 is a cross-sectional view taken along line VI-VI in FIG.

  The odor supply apparatus SP3 is provided with a sheet 41 instead of the transparent sheet 40 and a titanium dioxide 51 instead of the titanium dioxide 50 in the odor supply apparatus SP2.

  The sheet 41 may not be transparent, but is a sheet having a large number of through holes 41h and made of ceramic or the like. The titanium dioxide 51 is also provided with a large number of through holes 51h. The titanium dioxide 51 may not have the through holes 51H.

  In Example 3, the ceramic is provided with a large number of through holes 41h, and the light emitted from the optical fiber 10 reaches the titanium dioxide 51 through the through holes 41h, and acts as a photocatalyst, resulting in an odor. Erased.

  Further, in the above embodiment, the inner tube 20 or the outer tube 30 is a supply tube that supplies predetermined particles such as gas, odor, liquid, powder, etc. to the position of the human nose N after positive ionization or negative ionization. May be. In this way, if predetermined particles such as gas, odor, liquid, powder, etc. are ionized in advance and supplied to the nose N and light is applied to the excess particles, the decomposition of the ionized particles is promoted, If a photocatalyst such as titanium dioxide 51 is used in combination, the decomposition of the ionized particles is further promoted.

  In the above embodiment, instead of using light or a photocatalyst, air charged with positive ions or air charged with negative ions may be applied to the odor.

  That is, a supply pipe that forms a path for supplying predetermined particles to the position of a person's nose, and an ion supply means that supplies positively charged air or negatively charged air to the vicinity of the human nose A particle supply device having a discharge pipe for discharging particles present at the position of the human nose may be assumed.
