Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of anesthesia waste gas purification, and specifically to an anesthesia gas purification device. Background Art
[0002] Anesthesia in the operating room mainly refers to the use of drugs or other methods during surgery to temporarily make the patient lose consciousness or produce analgesia throughout the body or locally, so that surgeons can perform surgical operations. It is mainly divided into two categories: general anesthesia and local anesthesia. For general anesthesia and local anesthesia, activated carbon filtration can be used for anesthesia waste gas. Activated carbon is an effective adsorption material that can remove harmful substances such as organic compounds and odors in the waste gas, thereby achieving the purpose of purifying the waste gas. In the treatment of anesthesia waste gas, using activated carbon filtration is a common and effective method.
[0003] When purifying the waste gas, since the patient's exhaled gas carries hot steam, the hot steam is likely to condense into water droplets after hitting the exhaust pipe wall, and the water droplets will enter the interior of the filter tank along with the waste gas, thereby affecting the normal filtration of the waste gas filter tank. Therefore, an anesthesia waste gas purification device for collecting condensed water is proposed. Summary of the Invention

The plate body is fixed to the bottom of the spring.
[0016] In some embodiments, the connecting block is in the shape of a cuboid.
[0017] (III) Beneficial effects
[0018] Compared with the prior art, the present invention provides an anesthesia gas purification device, which has the following beneficial effects:
[0019] 1. When the waste gas with hot steam enters the collecting pipe through the intake pipe, due to the temperature difference, condensed water is generated on the inner side wall of the intake pipe and extends from the intake pipe into the collecting pipe. The condensed water flows into the inner bottom of the collecting pipe by its own gravity. Therefore, the condensed water can be collected, ensuring that the waste gas introduced into the filter cotton and the activated carbon layer is in a dry state.
[0020] 2. When the height of the condensed water collected in the collecting pipe is higher than the overflow pipe, the condensed water will be introduced into the filter cotton through the overflow pipe. The condensed water will be mixed with the filtered dust. When waste gas is connected to the intake pipe, the generated impact force will drive the collecting pipe to slide on the intake pipe. At this time, the pressing plate compresses the filter cotton, so that the mixed liquid in the filter cotton is squeezed into the space between the first partition plate and the second partition plate, and finally is discharged through the liquid outlet pipe, further cleaning the filter cotton and increasing the service life of the filter cotton.
[0021] 3. After long-term use of the anesthetic gas purification equipment, it is necessary to observe the saturation of the activated carbon layer. By pressing the pressing plate, the condensed water in the collection pipe is directly introduced into the activated carbon layer, and the plate body is rotated to seal the bottom of the third partition. At this time, the condensed water is soaked in the activated carbon layer. By observing the generation of bubbles, if the activated carbon is saturated, only a small amount of bubbles or no bubbles may be generated after being put into water; if it is not saturated, continuous and a large number of bubbles will be generated, which is convenient for the operator to operate on the activated carbon layer.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0035] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0036] In the present application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0037] In addition, in the present application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0038] In the related art, when purifying waste gas, the patient's exhaled gas carries hot steam, which easily condenses into water droplets after hitting the wall of the exhaust pipe. The water droplets will enter the interior of the filter tank along with the waste gas, thereby affecting the normal filtration of the waste gas filter tank. Therefore, an anesthetic waste gas purification device for collecting condensed water is proposed.
[0039] In order to solve the problems in the related technology to a certain extent, an embodiment of the present application provides an anesthetic gas purification device. When the waste gas with hot steam enters the collecting pipe through the air intake pipe, due to the temperature difference, condensed water is generated on the inner wall of the air intake pipe, extending from the air intake pipe to the collecting pipe. The condensed water flows into the inner bottom of the collecting pipe by its own gravity. Therefore, the condensed water can be collected, ensuring that the waste gas introduced into the filter cotton and the activated carbon layer is in a dry state.
[0040] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0041] Combination Figures 1 - 10 The embodiment of the present application provides the following technical solution: an anesthetic gas purification device, comprising a tank body 100, a top cover 110 is fixed on the top of the tank body 100, an air inlet pipe 120 is fixed on the top of the top cover 110, a three-way pipe 130 is fixed on the outer side wall of the top cover 110, a partition 150, a partition 2 160 and a partition 3 170 are arranged in sequence from top to bottom on the inner side wall of the top cover 110, and the outer side wall of the air inlet pipe 120 is slidably connected to the outer side wall of the top cover 110. There is a collecting pipe 210, and a pressure plate 220 is fixed to the outer wall of the collecting pipe 210. An air pipe 230 is arranged on the outer wall of the collecting pipe 210 near the top of the pressure plate 220. The air outlet end of the air pipe 230 passes through the pressure plate 220. The air pipe 230 is connected to the collecting pipe 210. An overflow pipe 240 is fixed to the outer wall of the collecting pipe 210 near the bottom of the air pipe 230. The overflow pipe 240 is connected to the collecting pipe 210.
[0042] Specifically, before use, the air intake pipe 120 is connected to the exhaust gas end. When in use, first, the exhaust gas is introduced into the collecting pipe 210 through the air intake pipe 120. Since the exhaust gas has heat, the inner wall of the air intake pipe 120 has condensed water. At this time, the condensed water flows into the inner bottom of the collecting pipe 210 due to its own weight and is collected by the collecting pipe 210. The exhaust gas is introduced into the filter cotton 300 through multiple air pipes 230. The filter cotton 300 can filter particulate matter such as dust in the waste. The filtered exhaust gas is introduced into the activated carbon layer 400 through the partition 1 150 and the partition 2 160. The activated carbon layer 400 removes organic compounds, odors and other harmful substances in the exhaust gas, thereby achieving the purpose of purifying the exhaust gas. Finally, the purified gas is discharged through the three-way pipe 130, and the condensed water in the collecting pipe 210 When the height is higher than the overflow pipe 240, the condensed water will be introduced into the filter cotton 300 through the overflow pipe 240, and the condensed water will fuse with the particulate matter in the filter cotton 300. When the exhaust gas is connected, an impact will be generated, and the collection pipe 210 will slide on the intake pipe 120 to buffer the impact. At this time, the pressure plate 220 will press the filter cotton 300, and squeeze the fused liquid in the filter cotton 300 through the partition 150 onto the partition 2 160, and finally be discharged through the liquid outlet pipe 140, so as to simply clean the filter cotton 300 and increase the service life of the filter cotton 300. The operator controls the sliding position of the collection pipe 210 on the intake pipe 120 by controlling the flow rate of the exhaust gas. The equipment for controlling the exhaust gas flow rate is not reflected in the accompanying drawings and belongs to the prior art, which will not be repeated here.
[0043] In some embodiments, the overflow pipe 240 is embedded in the inner wall of the pressing plate 220 .
[0044] Specifically, the pressure plate 220 hides the overflow pipe 240 therein.
[0045] In some embodiments, the overflow pipe 240 and the air pipe 230 are regularly arranged on the outer wall of the collecting pipe 210 , and a liquid outlet pipe 140 is fixed to the outer wall of the tank body 100 , and the liquid outlet pipe 140 extends between the partition 1 150 and the partition 2 160 .
[0046] Specifically, the plurality of overflow pipes 240 are evenly distributed in the pressure plate 220 , so that the condensed water can be evenly dispersed in the filter cotton 300 , and the squeezed liquid can be discharged through the liquid outlet pipe 140 .
[0047] In some embodiments, regularly arranged ventilation pipes are disposed on the top of the second partition 160 , and the ventilation pipes are staggered with the through holes on the first partition 150 .
[0048] Specifically, because the ventilation pipe is staggered from the through hole on the partition 150, the squeezed liquid will not be introduced into the activated carbon layer 400 through the ventilation pipe.
[0049] In some embodiments, a pressing plate 500 is fixed to the top of the collecting pipe 210, and the pressing plate 500 is slidably connected to the top cover 110.
[0050] Specifically, an operator can directly press the pressing plate 500, and the pressing plate 500 can directly press the pressing plate 500.
[0051] In some embodiments, a pipe body 620 is fixed to the top of the third partition plate 170, and a valve body 250 is arranged at the bottom of the collecting pipe 210. A rotating assembly is arranged inside the pipe body 620, and a plate body 610 is arranged at the bottom of the rotating assembly. When the collecting pipe 210 is pressed downward, the valve body 250 squeezes the rotating assembly, and the rotating assembly drives the plate body 610 to rotate, so that the plate body 610 is staggered from the through hole on the third partition plate 170. The rotating assembly includes a first sleeve 660. The first sleeve 660 and a second sleeve 670 are fixed to the inner side wall of the pipe body 620. The opposite surfaces of the first sleeve 660 and the second sleeve 670 have teeth. A spring 640 is arranged at the top of the second sleeve 670, a connecting block 650 is arranged at the top of the spring 640, the bottom of the spring 640 is fixed to the plate body 610, and the connecting block 650 is in the shape of a cuboid.
[0052] Specifically, when it is necessary to know the saturation condition of the activated carbon layer 400 after using for a period of time, the pressing plate 500 is pressed to drive the collecting pipe 210 to move downward. At this time, the connecting block 650 contacts the valve body 250, and the valve body 250 is jacked up by the connecting block 650. At this time, the water in the collecting pipe 210 is introduced into the activated carbon layer 400 through the opened through hole. While continuously pressing the pressing plate 500, when the valve body 250 reaches a certain height, it will press downward on the connecting block 650. The telescopic rod 630 on the connecting block 650 will rotate on the telescopic rod 630 and the second sleeve 670. The telescopic rod 630 is provided with a slider sliding on the tooth structure. The telescopic rod 630 drives the plate body 610 to rotate, so that the through hole of the plate body 610 is staggered from the through hole on the third partition plate 170, so that water will not flow out from the bottom of the activated carbon layer 400, and the activated carbon layer 400 is in an immersion state, so as to observe the bubble condition of the activated carbon and know the saturation condition of the activated carbon. The rotating assembly is similar to the pressing principle of a ballpoint pen in the prior art.
