Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the use of nitric oxide used in the treatment of artificial respirators and artificial circulators, or sample gas which cannot be used by a monitor, as it is indoors and outdoors. The present invention relates to a device for safely disposing of exhaled and surplus gas discharged after detoxification because it is dangerous due to harmful gas. [0002] In recent years, nitrogen oxides (NOx) including nitric oxide (NO) and nitrogen dioxide, which have become widespread as treatments for respiratory and circulatory disorders, cause headache and nausea. And so on. This is because the area around the ventilator attached to the patient is high, and nitric oxide breathed by the patient reacts with oxygen and the like in the ventilator to produce nitrogen dioxide (NO 2 ).
Etc., and are discharged into the room as waste gas. [0003] Exhaust sources of waste gas from the nitrogen oxide (NOx) gas breathing apparatus described above include a patient's breath, a gas collected by a gas concentration monitor, and a breath when mixed with an intermittent flow of a ventilator. There is excess gas in the phase, exhaled gas returned to the ventilator. Further, since high concentration oxygen is mixed in the waste gas from the nitric oxide gas breathing apparatus, nitrogen oxides (NOx) containing nitrogen dioxide (NO 2 ), which is highly toxic to living organisms and corrodes metals, rubber, etc. ) Exists. [0004] As described above, since nitric oxide is a very toxic gas to the living body, it does not allow nitric oxide gas to flow back to the oxygen and air lines. A circuit in which a mixed gas of nitric oxide gas and oxygen is not stored or stagnated. All used gases (exhaled gas and analysis gas) are rendered harmless and discharged indoors and outdoors. Nitric oxide gas in the inhaled air does not pass through the ventilator. Next, as an adsorption method, zeolite or activated carbon is used, or both of them inhibit water adsorption as a pretreatment because water takes precedence to inhibit adsorption of nitrogen oxides (NOx). In addition, a reusable silica gel (silicic anhydride) was used to remove water. [0005] In order to achieve the above object, a waste disposal apparatus according to the present invention comprises a silica gel cylinder containing silica gel therein between a top plate and a support. An activated carbon cylinder containing activated rock is set up inside. Then, the tip of the exhaust pipe is connected below the silica gel cylinder, the upper part of the silica gel cylinder is connected to the upper part of the activated carbon cylinder, and a gas flow meter is obtained from the lower part of the activated carbon cylinder to detect the nitrogen dioxide. It is to be discarded from a discharge pipe through a suction pipe laid more indoors. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to the drawings. The waste treatment apparatus main body (1) is movably mounted, and one of them is an exhaust gas through which expired gas and excess gas pass. Connect the conduit (2). The end of the exhaust pipe (2) is connected to the lower end of the silica gel cylinder (3) from the lower part of the support base (12). The silica gel cylinder (3) containing silica gel is formed of a transparent cylinder, and the silica gel inside is discolored when the water absorption capacity is reduced so that it can be replaced. [0007] Next, the silica gel cylinder (3) has a gas conduit (5) connected to the upper portion thereof via a top plate (11). The end of the gas conduit (5) is connected to the upper end of the activated carbon storage cylinder (6) through the top plate (11). The activated carbon inside the activated carbon storage cylinder (6) is accommodated in a transparent cylindrical shape. In addition, a synthetic zeolite can be used as the adsorbent. Further, a connecting pipe (7) having a lower end penetrating through the support (12) is connected to the activated carbon storage cylinder (6). The connecting pipe (7) is connected to a gas flow meter (8) having a float (14) inside and a scale (15) on the surface. Next, a nitrogen dioxide detector (9) is set up on the flow meter (8). The nitrogen dioxide detector (9) detects the concentration of the activated carbon by measuring the concentration based on the discolored body inside the nitrogen dioxide detector (9). Further, a discharge pipe (10) is connected to the nitrogen dioxide detector (9) on the side substantially below the position where the discolored body is displayed. The discharge pipe (1
In (0), since there is a suction pipe or an ejector other than a dedicated exhaust pump as needed inside and outside the room, the apparatus is connected to a discharge pipe using power. In addition, casters (21) and (21)
And a moving base (13) with a mounting. Furthermore,
An artificial respirator (16) communicating with the exhaust conduit (2) through which exhaled gas and surplus gas passes passes through a transfer tube (17) and a used monitor gas tube (18) on the way.
Is connected to the exhaust conduit (2) through the function of an interface (19) that is in communication with the intermittent flow conduit (20) of the ventilator. Sign (2
2) shows a fastening rod for linking the top plate (11) and the support base (12). The present invention is constructed as described above. To explain the usage, a mask is applied to the patient's nose, mouth, etc., and the transfer (1) is performed by operating the artificial respirator (16).
7), used monitor gas (18) and intermittent flow conduit (2)
Exhaled air and surplus gas via (0) and the interface (19) reach the exhaust conduit (2). From the exhaust conduit (2), water is first absorbed and removed through the silica gel cylinder (3) from below to above. Thereafter, the activated carbon storage cylinder (6) is penetrated downward from above through the gas conduit (5), and again performs the adsorption treatment of water and nitrogen dioxide inside.
Thereafter, the float (14) is floated from below the flow meter (8) through the lower connecting pipe (7), and the flow rate of the float is checked by the memory (15). The confirmed gas penetrates from below the nitrogen dioxide detector (9), and the concentration of the gas is confirmed by discoloration inside. The gas treated in the exhaust pipe (10) connected to the side of the nitrogen dioxide detector (9) is safely disposed of by the exhaust pump inside and outside the room. Since the present invention is configured as described above, a patient by inhalation therapy of nitric oxide, which has been widely used as a conventional remedy for respiratory and circulatory disorders, can be placed indoors. It has an excellent effect of preventing exhaled breath, headache caused by excess gas, and toxic symptoms. The exhaled gas and the nitrogen dioxide gas from the surplus gas exhaust conduit have the effect of adsorbing most of the moisture of the gas while passing through the inside of the first silica gel cylinder. Since the silica gel cylinder is connected to the activated carbon cylinder via a gas conduit, the gas passing through the activated carbon cylinder is removed of water by the silica gel first, so that the adsorption capacity as an adsorbent is significantly enhanced. There is such an excellent effect. In addition, since the activated carbon cylindrical body is provided with a nitrogen dioxide detector via a flow meter from the lower end via a connecting pipe, the flow rate of the gas can be accurately seen through the flow meter from the outside to confirm safety. At the same time, there is an effect that accurate determination can be made by the discoloration display of the discoloration detecting agent inside the nitrogen dioxide detector.
