The present invention relates to a moisture removal device for a CO₂ gas measurement system, and in particular, the CO₂ gas generated at the end of the exhalation of the patient passes through the curved passage of the moisture removal member formed of metal to remove moisture and then discharge the impact on the CO₂ module. The present invention relates to a moisture removal device for a CO2 gas measurement system that can effectively remove moisture from CO2 gas generated at the end of a patient's expiration.

In general, CO₂ gas generated at the end of exhalation (END-TIDAL) of the patient contains CO₂, and the measurement system for measuring CO₂ contained in this CO₂ gas can be operated to determine the patient's condition. This system consists of a CO2 module for measuring the CO contained in the CO2 gas that has passed through a patient-connected hose, a dehumidifier, and a dehumidifier.

This CO2 gas measurement system is usually used to connect with the breathing circuit during general anesthesia to determine if the room is well ventilated. In other words, if the ventilation is not supplied with oxygen, and fall into hypoxia. It is also used to determine whether the spontaneous breathing of the patient has returned, whether there is an abnormality in the valve of the breathing circuit, or whether the function of the absorbent of carbon dioxide has fallen.

As such, the end-tidal CO₂ gas supplied to the CO₂ module of the system contains moisture (saturation humidity of 100% at 36 ℃ -37.5 ℃). The difficulty of accurate measurement of the gas and the condensed water cannot guarantee the stability of the CO2 module.

6A and 6B of the accompanying drawings, there is shown a moisture removal apparatus (Disposable, Reusable Watertrap) according to the prior art. As shown, a moisture removal device 2 is installed between the patient and the CO 2 module 1.

First, the moisture removing device 2 shown in FIG. 6A is a water absorbing sponge 3 for removing moisture at a point where a CO 2 gas generated from a patient passes through a conventionally widely used and used method. ) Was absorbing / removing moisture. However, in this case, when the sponge 3 absorbs a certain amount of water, the sponge 3 hardens and reaches an air permeability of 0%. Therefore, there is a problem that the circuit of this part must be discarded and replaced. In addition, since the one-time moisture removal device (Disposable Type Watertrap) including the moisture absorbing sponge 3 was expensive compared to the use time, there was also a problem in that a relatively high cost was required.

In addition, as shown in FIG. 6B, a system in which a water trap (Reusable Watertrap Type) 4 is installed between the patient and the CO 2 module 1 is disclosed. In this case, the system is developed for the same purpose as the one-time moisture removal device described above. It is sold. Looking more specifically as follows.

CO2 gas generated from the end of the exhalation of the patient is introduced into the expanded interior of the water trap (4). At this time, when looking at the internal structure, there is only one passage that separates water and induces water into the drip tray container. Therefore, in the through passage that induces water during the operation of the CO₂ module (1), the air intake / exhaust of the drip container space is generated after a certain time. Moisture inhalation / discharge occurs simultaneously. However, due to the surface tension of the condensed water droplets, there was a disadvantage in that circulation of the air and the moisture generated in the container was not smoothly performed in a small passage within 1-2 mm in diameter. In this case, the CO2 gas is completely dependent on the filtering according to the permeability of the filter. Therefore, the CO2 gas pz permeability introduced during operation and sucked into the CO₂ module (1) is an advantage in terms of the protection of the CO₂ module (1) during operation, but it puts a considerable burden on the suction motor installed in the CO₂ module (1). The results also show that the average CO2 gas error range is not well below the average. Therefore, there was a problem of providing a cause for the doctor to misdiagnose.

The present invention has been made in order to solve the problems of the prior art as described above, the technical problem of the present invention is to pass the CO₂ gas through the passage having a different volume for each section, the moisture contained in the CO₂ gas passage volume and inflow rate The present invention provides a moisture removal device capable of effectively removing moisture contained in CO 2 gas by compressing / expanding by a minute pressure difference and the like, and naturally cooling and condensing by an original metal temperature.

When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention having such features as follows.

As shown in FIGS. 1 to 3, in the accompanying drawings, the moisture removing device according to the present invention includes a moisture removing member 20 for discharging CO 2 gas through a passage 24F having different volumes to remove moisture, and then discharge the moisture. , Installed in the water trap member 30 and the moisture removing member 20 to receive moisture condensed and condensed from the CO 2 gas branched from the moisture removing member 20 or to remove excess moisture and foreign matter contained in the gas. It consists of a filtration member 40 for filtering the discharged CO 2 gas.

This will be described in more detail as follows.

1 and 3 in the accompanying drawings, the moisture removing member 20 passes the CO 2 gas generated and introduced at the end of the exhalation of the patient through the curved passage 24F having different volumes. After condensing moisture contained in the gas, most of the CO 2 gas removed by condensation of moisture is discharged to the CO₂ module 50 side, and the other part is passed through other components to be discharged to the CO₂ module 50 side. It consists of a body 22 to pass and branch the incoming CO 2 gas into the curved passage 24F, and a condensation member 24 installed inside the body 22 to form the curved passage 24F.

First, as shown in FIGS. 1 to 3, the body 22 has an inlet 22A for introducing CO 2 gas into one side thereof, and a connection groove 22B having a lower portion communicating with the inlet 22A. It is formed in the upper and lower directly, the other side is formed with a main discharge port (22C) in communication with the upper portion of the connection groove 22B, the bottom surface is in communication with the bottom of the connection groove 22B and the water trap member (30) 22D is formed, and one side of the connection hole 22D is provided with an auxiliary outlet 22E for discharging CO 2 gas circulated through the water trap member 30 to the main outlet 22C. Has a structure. At this time, the auxiliary outlet 22E has a wide inlet and a narrower outlet than the inlet.

The inner diameter of the main outlet 22C is larger than that of the connecting hole 22D. For example, when the main outlet 22C is about 2.0 mm, the connecting hole 22D is formed to be about 1 mm. This is to ensure that most of the CO2 gas introduced into the main outlet 22C.

The body 22 may be formed of aluminum or ceramic, but is preferably formed of aluminum or an alloy thereof in consideration of workability. This is to allow the gas to cool when the CO2 gas is contacted because the metal has a lower temperature than the gas.

On the other hand, the condensation member 24 bends the CO 2 gas introduced so that the water contained in the CO 2 gas introduced into the inlet 22A of the body 22 is condensed and removed, and then the main outlet 22C and the connection hole ( 22D) is installed in the connection groove 22B to branch and discharge, respectively, and is inserted into the connection groove 22B and has an insertion end having at least two or more airtight holding members 24A ( The passage 24F is formed in 24B.

Looking at this in more detail as follows.

2 and 3, the condensation member 24 forming the curved passage 24F is inserted between the airtight holding members 24A so as to communicate with the inlet 22. A horizontal passage 24C formed on an outer circumferential surface and having a smaller volume than that of the inlet 22, and inclined from the upper portion of the outer circumferential surface of the insertion end 24B to the lower inner side thereof so that the upper side is connected to the horizontal passage 24C. A communication passage 24D having a larger volume than the horizontal passage 24C and a lower side of the connection passage 24D, and having a larger volume than the connection passage 24D, and having a lower portion connected to the connection passage 24D. Expansion portion 24E-1 communicating with the ball 22D, formed on the upper portion of the expansion portion 24E-1 so as to communicate with the main outlet 22C, and a smaller volume than the expansion portion 24E-1. And having a vertical passage 24E having a narrow portion 24E-2 formed to be bent toward the main discharge port 22C. The. At this time, the vertical passage 24E has a large inlet (extension) and a narrow outlet (narrow) facing the main outlet 22C, and the upper side is curved in the horizontal direction (main outlet direction) again as described above. Has a structure.

The upper outer peripheral surface of the condensation member 24 may be further provided with a hermetic holding member. The horizontal passage 24C, the connection passage 24D, and the vertical passage 24E communicate with each other to form one refracted passage 24F having different volumes as shown in FIG. That is, each section formed by the semicircular horizontal passage 24C, the connection passage 24D, and the vertical passage 24E has a different volume (inner diameter). Thus, the velocity of the gas passing through this passage 24F can be varied, thereby compressing or expanding it with a slight pressure difference.

As such, the condensation member 24 forming the passage 24F may be formed of any one material selected from aluminum, an aluminum alloy, and ceramics, such as the body 22 described above. desirable. This is because the CO2 gas generated at the end of the exhalation of the patient has a temperature of 36 ° C. to 37 ° C., so when the CO2 gas at this temperature passes through the passage 24F, the moisture contained in the CO₂ gas is caused by the inherent low temperature of the metal material. It is for cooling and condensation. That is, since the temperature of the metal condensation member 24 is lower than the temperature of the CO 2 gas, the moisture contained in the CO 2 gas is expanded by the pressure difference as it passes through the condensation member 24 and contacts the condensation member 24. It can be removed by condensation while cooling naturally.

Meanwhile, as illustrated in FIGS. 1 and 3, the water trap member 30 removes a part of moisture contained in the CO 2 gas discharged from the moisture removing member 20 and flows into the moisture removing member 20. And a pair of through holes 32A corresponding to the connection hole 22D and the auxiliary outlet port 22E, and having an airtight holding member 32B on the outer circumferential surface thereof to store the moisture generated and agglomerated. The balance between the coupling member 32 coupled to the bottom of the body 22 with bolts and the pressure of the CO 2 gas and the discharged CO 2 gas installed at each of the through holes 32A at the bottom of the connection member 32 is discharged. Each nozzle (34A, 34B) for adjustment and the water storage container 36 is coupled to the lower portion of the connecting member 32 formed to receive water. The moisture storage container 36 is formed of a non-toxic silicone material that can be deformed and coupled to the lower portion of the connection member 32 by interference fit.

At this time, the inner diameter of the inlet side nozzle 34A is the same as the connection hole 22D, but the inner diameter of the outlet side nozzle 34B has an inner diameter about half the size of the inlet side nozzle 34A. This is to allow the gas introduced into the connection hole 22D to have a resistance while passing through the discharge side nozzle 34B so that most of the gas is discharged to the main discharge port 22C.

On the other hand, the filtering member 40 is to filter the CO₂ gas moving through the moisture removal member 20 and the water trap member 30 to the CO₂ module 50, as shown in Figures 1 and 3 Likewise, the filter 42 is installed on the other side of the body 22 so as to contact the main outlet 22C and the auxiliary outlet 22E, and a discharge hole 44A is formed at a position corresponding to the filter 42. A filter fitting hole 44 coupled to the body 22 with bolts so that the filter 42 is installed in close contact with the body 22 and installed in the discharge hole 44A. It consists of a connector 46 for supplying the CO₂ gas passed through the filter 42 to the CO₂ module 50. The filter 42 can be replaced by removing the filter fitting 44.

Referring to the operation according to a preferred embodiment of the present invention configured as described above are as follows.

In the accompanying drawings, as shown in FIG. 3, a nozzle is connected to the inlet port 22A formed on the body 22 of the moisture removing member 20 to be connected to the hose, and the condenser member 24 is connected to the connection groove 22B. ) Is inserted and installed, the water trap member 30 is coupled to the lower portion of the body 22 by the connecting member 32, the filtering member 40 is installed on the other side of the body 22 is the connector ( 46 is connected to the CO2 module 50, thereby completing the use of the moisture removing device according to the present invention.

In this state, the CO 2 gas generated by the end of exhalation of the patient flows into the inlet port 22A formed in the body 22 of the moisture removing member 20 through the hose.

Subsequently, the CO 2 gas introduced into the inlet port 22A passes through the passage 24F formed in the condensation member 24 as shown in FIGS. 2 and 3.

This will be described in more detail. First, the CO2 gas introduced through the inlet port 22A passes through a horizontal passage 24C consisting of a pair of semicircular shapes. At this time, the CO 2 gas introduced from the inlet port 22A passes through a horizontal passage 24C having a volume different from that of the inlet port 22A at a different speed from that of the inlet port 22A, and thus has a different pressure from that of the inlet port 22A. Then, while being in contact with the metal condensation member 24 is naturally cooled by the low temperature of the condensation member 24.

Subsequently, the CO 2 gas passing through the horizontal passages 24C on both sides moves to the connection passage 24D. At this time, the CO2 gas has a different moving speed and corresponding pressure than in the horizontal passage 24C. This is because the volume of the horizontal passage 24C and the connecting passage 24D is different, and the CO₂ gas is compressed by the pressure difference due to the minute volume and the inflow (movement) speed difference between the horizontal passage 24C and the connecting passage 24D. It goes through an expansion process.

On the other hand, the CO2 gas is introduced into the expansion portion 24E-1 of the vertical passage 24E through the connection passage 24D. At this time, since the inner diameter (volume) of the vertical passage 24E is remarkably larger than the inner diameter (volume) of the connection passage 24D, the expansion portion 24E of the vertical passage 24E that is rapidly moved and expanded at a high pressure. The CO2 gas introduced into -1) becomes low temperature and low pressure state as it expands, and the moisture contained in this CO₂ gas is condensed at the low temperature (cooling), and thus the moisture contained in the CO₂ gas is removed. In addition, since the condensation member 24 is formed of a metal material to maintain a lower temperature than the CO 2 gas, the moisture contained in the CO 2 gas may be more naturally cooled and condensed.

Most of the CO2 gas introduced into the expansion portion 24E-1 of the vertical passage 24E passes through the narrow portion 24E-2 formed at the upper side of the expansion portion 24E-1, and the main discharge port 22C. Is discharged to the filtration member 40 side, the remaining CO2 gas is communicated with the lower portion of the vertical passage 24E and the water trap member 30 through the connection hole (22D) formed with a smaller inner diameter than the main discharge port (22C) Go to.

In summary, the CO2 gas introduced into the inlet port 22A is divided into the horizontal passage 24C section, the connecting passage 24D section, and the vertical passage 24E-1 and narrow section 24E-2 section. It is compressed (high pressure) and expanded (low pressure) by the pressure difference according to the different volume and the difference in inflow rate through each section. Is made easily.

That is, moisture contained in the CO 2 gas passing through the curved passage 24F formed by the condensation member 24 is cooled while being in contact with the surface of the condensation member 24 having a lower surface temperature than the temperature of the CO 2 gas. In addition, the pressure difference between each section, in particular, flows into the vertical passage 24E extended from the narrow connection passage 24D and expands to become a low temperature and low pressure to condense.

Most of the CO 2 gas from which moisture is removed through this process is discharged through the main outlet 22C, and CO 2 gas and moisture, which are not removed from the moisture, are introduced into the water trap member 30 through the connection hole 22D. . At this time, since the inner diameter of the connection hole 22D is smaller than the inner diameter of the main discharge port 22C, most of the gas is discharged to the main discharge hole 22C.

This will be described in more detail as follows.

As shown in FIG. 3, some of the CO 2 gas introduced into the water trap member 30 through the connection hole 22D of the body 22 passes through the water storage container 36 through the inlet side nozzle 34A. After the residual moisture and foreign matters are removed, they are discharged to the auxiliary discharge port 22E through the discharge side nozzle 34B. At this time, for example, when the inner diameter of the main discharge port 22C is 2 mm, the inner diameter of the connecting hole 22D is 1 mm, the inner diameter of the inflow nozzle 34A is 1 mm, and the inner diameter of the discharge nozzle 34B is 0.5 mm. Since the gas flowing into the condensation member 24 passes through the connection hole 22D and the nozzle 34A having an inner diameter of 1 mm and the discharge nozzle 34B having a diameter of 0.5 mm, the gas is largely resisted. It is discharged to the main discharge port 22C side receiving less resistance than the water trap member 30 side than the water trap member 30 receives the.

Therefore, most of the gas introduced into the condensation member 24 (approximately, 87.5% is discharged to the main discharge side, and the remaining 12.5% is discharged to the water trap member side) is discharged to the main discharge port 22C side.

Thus, each nozzle 34A, 34B of the water trap member 30 adjusts the gas flow by adjusting the pressure (resistance) of the gas.

Subsequently, the CO 2 gas discharged from the body 22 through the main outlet 22C and the auxiliary outlet 22E passes through the filter 42 of the filtration member 40 to remove residual foreign matter.

The CO₂ gas from which the foreign matter is removed while passing through the filtration member 40 is moved to the CO₂ module 50 through the connector 46, and the CO₂ module 50 measures the supplied CO₂ gas.

On the other hand, Figure 4 and Figure 5 of the accompanying drawings shows a second preferred embodiment according to the present invention.

4 and 5, the moisture removing device according to the second embodiment is formed spirally from the lower end of the outer peripheral surface of the insertion end 22B between the airtight holding members 24A to the upper side, and is formed at the inlet 22D. It has the same volume as the first embodiment except that it has a smaller volume and has an inclined passage 24G connecting the inlet port 22A and the connecting passage 24D.

That is, since a pair of inclined passages 24G are formed to be inclined from one outer peripheral surface side of the insertion end 22B to the other side, the CO 2 gas introduced into the inlet port 22A is connected to the connecting passage 24D through the inclined passages 24G on both sides. In this process, the CO2 gas stays in the inclined passageway (24G) for a longer time, thereby increasing the condensation rate of the moisture.

As the CO2 gas generated at the end of the patient's exhalation passes through the curved passage 24F of the metal condensation member, moisture is removed, and since most of the CO2 gas is supplied directly to the CO2 module 50, Accurate measurement is possible.

The moisture removal device for the CO₂ gas measurement system according to the present invention passes the CO₂ gas generated by the end of the patient's exhalation through the curved passage of the metal moisture removal member, so that the volume is different when the CO₂ gas passes through the passage. The moisture contained in the CO₂ gas can be condensed and removed by the compression / expansion action due to the minute pressure difference of the CO₂ gas passing through each section of the passage and the temperature difference of the CO2 gas and the metal moisture inhibitor. Therefore, the CO₂ module can accurately measure the CO₂ contained in the CO₂ gas.
