This invention relates to the field of carbon dioxide absorber technology, and in particular to a multifunctional anesthetic gas carbon dioxide absorber, comprising: an anesthetic gas cylinder, an absorption unit slidably mounted on the anesthetic gas cylinder, and a connecting unit fixedly mounted on the absorption unit. During gas anesthesia operations using the anesthetic gas cylinder, the breathing tube can be quickly clamped and fixed by inserting it into the connecting assembly, completing rapid tubing assembly. The carbon dioxide exhaled by the patient is delivered into the device assembly, guided and diverted by the inner wall guide assembly, and then enters the absorption assembly.

Description

Technical Field

[0001] This invention relates to the field of carbon dioxide absorber technology, and more particularly to a multifunctional anesthetic gas carbon dioxide absorber. Background Technology

[0002] Anesthesia gas cylinders and their connected anesthetic tubing generally adopt a closed-loop operating mode. The mixed gas exhaled by the patient, containing carbon dioxide, oxygen, and anesthetic gas, needs to be passed into a carbon dioxide absorber. The CO2 is removed by the chemical reaction between the carbon dioxide and the internal soda lime and calcium lime. The purified gas is then returned to the breathing circuit for recycling through the outlet tube. The overall gas flow is that the exhaled gas enters the absorber through the inlet tube, is decarbonized, and is sent back to the tubing through the outlet tube. As a key component of this closed-loop anesthesia system to achieve gas reuse, the ease of disassembly and assembly and the filtration performance of the carbon dioxide absorber directly affect the safety of clinical use and the anesthetic effect.

[0003] The existing carbon dioxide absorber has a fixed connection between the pipeline interface and the anesthetic gas cylinder, making disassembly and replacement inconvenient. If the cylinder is not replaced in time, residual microorganisms inside can easily lead to cross-infection risks. At the same time, the soda lime and calcium lime adsorption media used will generate byproducts such as fluoromethyl, carbon monoxide, and formaldehyde when adsorbing carbon dioxide and coming into contact with volatile anesthetic drugs. Long-term exposure can have adverse effects on health. In addition, the internal filtration structure of the absorber will cause uneven contact between the gas and the filter material, and some filter materials cannot fully perform their adsorption performance, which increases the cost of consumables.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1, referring to Figure 1 - Figure 3 The first embodiment of the present invention provides a multifunctional anesthetic gas carbon dioxide absorber. The device includes: an anesthetic gas cylinder 1, an absorption unit 2 slidably mounted on the anesthetic gas cylinder 1, and a connecting unit 3 fixedly mounted on the absorption unit 2.

[0031] The absorption unit 2 includes a device assembly 21 that is slidably mounted on the anesthetic gas cylinder 1, a guide assembly 22 that is fixedly mounted on the inner wall of the device assembly 21, and an absorption assembly 23 that is fixedly mounted on the inner wall of the device assembly 21. The absorption assembly 23 is fixedly connected to the guide assembly 22. The device assembly 21 can be quickly disassembled from the anesthetic gas cylinder 1 as a whole, which facilitates timely replacement and cleaning of the cylinder.

[0032] Furthermore, the connection unit 3 includes a connection component 31 fixedly installed on the equipment component 21; during anesthesia, the breathing tube is inserted into the connection component 31, and the connection component 31 quickly clamps and fixes the breathing tube, thereby realizing the rapid assembly of the breathing circuit and establishing a gas passage for the patient to carry out gas anesthesia.

[0033] During use, when performing gas anesthesia with the anesthetic gas cylinder, the breathing tube is first inserted into the connecting component 31, which quickly clamps and fixes the breathing tube, completing the rapid assembly of the breathing circuit. Then, gas anesthesia is administered to the patient. The carbon dioxide exhaled by the patient during anesthesia enters the equipment component 21. The guide component 22 set on the inner wall of the equipment component 21 guides the exhaled gas. The diverted gas enters the absorption component 23, which further diverts the gas and forms a rotating turbulent flow, causing the airflow to be fully disturbed in the cavity. This allows the carbon dioxide to come into uniform and sufficient contact with the non-alkaline calcium lime and lithium-based absorbent filled inside the absorption component 23, completing the adsorption and removal of carbon dioxide. The gas after absorption treatment continues to flow through the filter element 238, completing secondary filtration and adsorption to remove dust and trace impurities from the gas. The purified gas is sent back to the anesthetic gas cylinder 1 for reuse in the anesthesia cycle.

[0034] Meanwhile, the entire equipment component 21 can be quickly disassembled and assembled with the anesthetic gas cylinder 1, facilitating timely replacement and cleaning of the cylinder. This overcomes the problems of traditional carbon dioxide absorbers being fixedly connected to the anesthetic gas cylinder pipeline, which are inconvenient to disassemble and maintain, prone to cross-infection due to microorganisms remaining in the cylinder, and have a single internal airflow direction, uneven filter material contact, and low consumable utilization rate. This device optimizes the gas flow field in the cavity by using swirling turbulence to improve the effective utilization rate of the absorbent, and improves the cleanliness of the circulating anesthetic gas by relying on dual absorption and filtration, ensuring the safe operation of the anesthetic circuit.

[0035] This equipment uses non-alkaline calcium lime, lithium-based absorbent, and nano-calcium lime as the carbon dioxide adsorption medium, replacing traditional soda lime and ordinary calcium lime. The non-alkaline calcium lime does not contain strongly alkaline components such as sodium hydroxide and potassium hydroxide, while the lithium-based absorbent and nano-calcium lime incorporate lithium chloride as a catalytic component. Compared with traditional adsorption materials, this new type of adsorption medium does not generate toxic byproducts such as fluoromethyl compounds, carbon monoxide, and formaldehyde when adsorbing carbon dioxide and coming into contact with volatile anesthetic agents. At the same time, it releases less dust, thus eliminating the health hazards of toxic substances and irritating dust to patients and medical staff.

[0036] Meanwhile, the cost of non-alkaline calcium lime is moderate and it is directly compatible with the cavity structure of this device; the lithium-based absorbent has high catalytic efficiency and a longer effective service life. Combined with the internal swirling turbulence structure of this device, the airflow can be evenly distributed inside the absorption cavity, allowing the non-alkaline calcium lime and lithium-based absorbent to fully participate in the carbon dioxide adsorption reaction. This avoids excessive consumption of local consumables and waste of other media, effectively improving the utilization efficiency of the adsorption medium, reducing the frequency of consumable replacement, and lowering clinical usage costs. At the same time, this adsorption medium, together with the multi-layer filter discs in the filter element, can further intercept trace amounts of dust escaping from the medium, ensuring the cleanliness of the gas in the anesthesia circulation circuit.

[0037] Example 2, refer to Figure 1 - Figure 9 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the device component 21 includes a protective shell 211 that is slidably mounted on the anesthetic gas cylinder 1, a connecting shell 212 that is fixedly mounted on the protective shell 211, and a pressure gauge 213 that is fixedly mounted on the connecting shell 212. The device component 21 as a whole can be slidably disassembled and assembled relative to the anesthetic gas cylinder 1, which facilitates quick replacement of the cylinder and internal disinfection, and can reduce the risk of cross-infection caused by microbial residues in the cylinder. The pressure gauge 213 is used to monitor the gas pressure status inside the anesthetic circuit in real time.

[0038] Compared to Embodiment 1, the guide assembly 22 further includes a check valve 221 fixedly installed on the inner wall of the connecting shell 212, and a guide 222 fixedly installed on one side of the check valve 221, and the guide 222 is fixedly connected to the connecting shell 212; after the mixed gas exhaled by the patient is sent into the connecting shell 212 by the connecting assembly 31, it first passes through the check valve 221 to realize the one-way flow of gas, and then passes through the guide 222 to complete the initial flow diversion of airflow, so that the gas is evenly dispersed in the cavity of the connecting shell 212.

[0039] Furthermore, the anti-reverse component 221 includes a baffle 2211 fixedly installed on the connecting shell 212, a rotating rod 2212 rotatably installed on the inner wall of the baffle 2211, and a rotating plate 2213 fixedly installed on the rotating rod 2212, with the rotating plate 2213 slidably connected to the baffle 2211. When the airflow impacts the rotating plate 2213, the rotating plate 2213 can be flipped by the rotating rod 2212, allowing the gas to flow backward through the baffle 2211. When the airflow impact force disappears, the rotating plate 2213 returns to its original position by its own gravity, sealing the ventilation channel of the baffle 2211, preventing gas backflow, and ensuring unidirectional gas flow inside the circuit.

[0040] Furthermore, the guide member 222 includes a guide plate 2221 fixedly installed on the connecting shell 212, and a conical plate 2222 fixedly installed on the guide plate 2221; the gas passing through the anti-reverse member 221 impacts the surface of the conical plate 2222, and the initial airflow is guided and dispersed by the conical plate 2222, which can promote the gas to be fully dispersed and distributed in the cavity of the connecting shell 212.

[0041] Furthermore, the absorption assembly 23 includes a diversion plate 231 fixedly installed on the inner wall of the protective shell 211, a filter element 238 fixedly installed on the inner wall of the diversion plate 231, a guide element 232 fixedly installed on the outer wall of the filter element 238, a first filter plate 233 fixedly installed on the outer wall of the filter element 238, a second filter plate 234 fixedly installed on the outer wall of the filter element 238, and a second conical plate 235 fixedly installed on the outer wall of the filter element 238. The second conical plate 235, the second filter plate 234, the first filter plate 233, and the guide element are all fixedly installed on the outer wall of the filter element 238. All components 232 are fixedly connected to the inner wall of the protective shell 211. The gas that has completed the initial diversion through the guide component 22 passes through the diversion plate 231 and enters the guide component 232, forming a spiral downward swirling airflow. During the downward movement of the airflow, it comes into contact with the non-alkaline calcium lime and lithium-based absorbent filled in the cavity, completing the initial chemical adsorption of carbon dioxide. The swirling gas continues to descend and passes through the first filter plate 233 and the second filter plate 234 in sequence to block the gas distribution in layers, further dispersing the airflow and allowing the gas to fully contact the absorption medium to achieve secondary adsorption filtration.

[0042] Furthermore, the filter element 238 includes a filter tube 2381 fixedly installed on the inner wall of the diverter plate 231, a filter disc 2382 fixedly installed on the inner wall of the filter tube 2381, a filter disc 2383 fixedly installed on the inner wall of the filter tube 2381, and a condenser 2384 fixedly installed on the filter disc 2383, and the condenser 2384 is fixedly connected to the filter tube 2381; after the gas reaches the bottom of the protective shell 211, it reverses direction and flows upward into the filter tube 2381. During the upward flow, the filter disc 2383 and the filter disc 2382 intercept the particulate matter and dust in the gas step by step, while the gas continues to contact the absorption medium inside the filter tube 2381 to deeply adsorb residual carbon dioxide; the condenser 2384 is used to capture the water vapor carried by the gas and condense the gaseous water vapor into liquid water.

[0043] Furthermore, the flow guide 232 includes a flow guide plate 2321 fixedly installed on the outer wall of the filter tube 2381, and a flow guide strip 2322 fixedly installed on the flow guide plate 2321. When the gas flows through the flow guide plate 2321 and the flow guide strip 2322, a spiral downward swirling airflow is formed under the combined guiding effect of the two, which can enhance gas disturbance and increase the contact probability between the gas and the absorption medium.

[0044] Furthermore, a guide strip 236 is fixedly installed on the conical plate 235, and a flow guide groove 237 is fixedly installed on the conical plate 235; when the downward airflow reaches the top of the conical plate 235, the guide strip 236 will turbulently distribute the gas, and then the gas will be introduced into the bottom of the protective shell 211 through the flow guide groove 237.

[0045] Furthermore, a drainage component 239 is fixedly installed at the bottom of the protective shell 211, and the drainage component 239 is slidably connected to the anesthetic gas cylinder 1; the reaction water generated by the chemical reaction between carbon dioxide and absorbent, the condensate condensed from the gas flow, and the liquid water condensed by the condenser 2384 all drip down and collect in the drainage component 239, which can be discharged in a centralized manner.

[0046] During use, when filtering exhaled carbon dioxide gas, the mixed gas exhaled by the patient is first delivered to the cavity of the connecting shell 212 via the connecting component 31. The airflow impacts the rotating plate 2213 inside the baffle 2211. When the gas thrust acts on the rotating plate 2213, the rotating plate 2213 rotates along the rotating rod 2212, allowing the gas to pass through the baffle 2211 and impact the conical plate 2222 on the guide plate 2221. The conical plate 2222 completes the initial diversion of the airflow, making the gas evenly dispersed inside the connecting shell 212. When the airflow stops impacting, the rotating plate 2213 returns to its original position by its own gravity, closing the channel of the baffle 2211 and playing a backflow prevention role, which can effectively prevent gas backflow and ensure unidirectional gas flow.

[0047] The gas, after its initial diversion, passes through the diversion plate 231 and reaches the guide plate 2321. Under the guidance of the guide plate 2321 and the guide strip 2322, it forms a downward spiral airflow. During the downward flow, the airflow first contacts the non-alkaline calcium lime and lithium-based absorbent filled in the cavity, completing the initial chemical adsorption of carbon dioxide. The spiral gas continues to descend, passing through the layered blocking and gas distribution of the first filter plate 233 and the second filter plate 234 in sequence, further dispersing the airflow so that the gas can fully contact the absorption medium and complete the secondary adsorption filtration. Subsequently, the gas reaches the top of the second conical plate 235, where the guide strip 236 implements secondary turbulence and gas distribution, and then passes through the guide groove 237 into the bottom of the protective shell 211.

[0048] Meanwhile, the reaction water generated by the chemical reaction between carbon dioxide and the absorbent, as well as the condensate from the condensation of the gas flow, drips downwards and collects at the bottom drain 239. After most of the carbon dioxide has been removed, the gas reverses direction and enters the filter tube 2381. During its upward movement, the gas passes through filter disc 2383 and filter disc 2382 in sequence to complete multi-stage interception and filtration of particulate matter and media dust. At the same time, it continues to come into full contact with the non-alkaline calcium lime and lithium-based absorbent remaining inside the filter tube 2381 to deeply adsorb the residual carbon dioxide. The condenser 2384 set inside the filter tube 2381 can capture the water vapor carried in the condensed gas. The condensed liquid water also collects and flows into the drain 239 for centralized discharge.

[0049] The purified gas, after undergoing multi-stage swirling gas distribution, chemical adsorption, multi-stage filtration, and water vapor condensation treatment, is finally transported back to anesthetic gas cylinder 1 through filter tube 2381, completing the closed-loop circulation of the entire anesthetic gas. Simultaneously, the multi-stage swirling turbulence structure improves the airflow distribution within the cavity, preventing local airflow short-circuiting and enhancing the overall utilization rate of the absorption medium. The multi-stage filtration combined with the water vapor condensation structure improves the cleanliness of the circulating anesthetic gas. Furthermore, the equipment adopts a modular, quick-disassembly structure, facilitating timely cylinder replacement and internal disinfection, reducing the risk of cross-infection caused by microbial residues. The selected non-alkaline calcium lime and lithium-based composite and nano-calcium lime absorption media can inhibit the generation of toxic byproducts such as carbon monoxide and formaldehyde when the media comes into contact with volatile anesthetic drugs. All three media can be used together or sequentially, reducing consumable consumption, shortening preoperative assembly preparation time, and improving the overall machine's carbon dioxide adsorption and purification capacity and clinical safety.

[0050] The remaining structure is the same as that in Example 1.

[0051] Example 3, referring to Figure 1 - Figure 10This is the third embodiment of the present invention, which differs from the second embodiment in that: the connecting assembly 31 includes a connecting pipe 311 fixedly installed on the connecting shell 212, a rotating shaft 312 rotatably installed on the inner wall of the connecting pipe 311, and a sealing ring 313 fixedly installed on the rotating shaft 312, and the sealing ring 313 is slidably connected to the connecting pipe 311; when gas flows into the interior of the connecting pipe 311, the airflow impacts the sealing ring 313, which can push the sealing ring 313 to slide along the inner cavity of the connecting pipe 311 along the rotating shaft 312, opening the gas passage and allowing the gas to be transported backward to the equipment assembly 21 for carbon dioxide filtration and absorption; when no gas enters the pipeline, the sealing ring 313 slides back to its original position under the combined action of the limiting force of the rotating shaft 312 and its own gravity, re-sealing the internal passage of the connecting pipe 311, preventing gas leakage and the intrusion of external air, and ensuring the overall sealing of the equipment assembly 21.

[0052] Compared to Embodiment 2, the further improvement of this embodiment is as follows: a connecting ring 314 is fixedly installed on the connecting tube 311, a latching rod 315 is rotatably installed on the inner wall of the connecting ring 314, and a sealing gasket 316 is also fixedly installed on the inner wall of the connecting ring 314, and the sealing gasket 316 is fixedly connected to the connecting tube 311; before performing carbon dioxide filtration, the gas delivery tube is inserted into the connecting ring 314, and the latching rod 315 is manually squeezed, so that the latching rod 315 can rotate inside the connecting ring 314, thereby completing the clamping and fixing of the gas delivery tube. The sealing gasket 316 will seal the joint between the connecting tube 311 and the connecting ring 314 to prevent air leakage at the interface, and provide a reliable gas path sealing basis for the subsequent adsorption and filtration of anesthetic gas.

[0053] Before commencing carbon dioxide filtration, insert the gas delivery tube into the connecting ring 314 and manually squeeze the locking rod 315 to rotate it within the connecting ring 314. During rotation, the locking rod 315 clamps and secures the gas delivery tube, while the sealing gasket 316 simultaneously seals the connection between the connecting tube 311 and the connecting ring 314 to prevent leakage. When gas flows into the connecting tube 311, the airflow impacts the sealing ring 313, pushing it to slide along the inner cavity of the connecting tube 311 with the assistance of the rotating shaft 312. This opens the channel, allowing the gas to be delivered to the equipment component 21 for carbon dioxide filtration and absorption. When no gas enters the pipeline, the sealing ring 313 slides back to its original position under the combined action of the rotating shaft 312 and its own weight, resealing the internal channel of the connecting tube 311 to prevent gas leakage and external air intrusion. This ensures the overall sealing of the equipment component 21 and provides a reliable gas path sealing foundation for subsequent anesthetic gas adsorption and filtration.

[0054] The remaining structure is the same as that in Example 2.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
