Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anesthetic waste gas purification, and particularly to an anesthetic gas purification device for clinical medicine in anesthesiology. BACKGROUND

[0002] In clinical medicine in anesthesiology, anesthetic waste gas (such as sevoflurane, isoflurane, nitrous oxide, etc.) generated in the operating room will not only pollute the indoor and outdoor environment if directly discharged, but also may cause chronic health damage to medical staff. In order to solve the problems of easy environmental pollution and damage to medical staff, the existing technology usually uses a waste gas purification device placed in the operating room to purify the waste gas. The purification principle generally uses ultraviolet light to irradiate the catalyst to react with the waste gas, and finally oxidize and decompose into harmless gas. However, the existing anesthetic waste gas purification device still has some deficiencies in actual use.

[0003] In the traditional fixed bed photocatalytic equipment, the catalytic material is easy to accumulate and agglomerate, which may cause insufficient gas-solid contact area. Moreover, the light source in the existing purification device is generally arranged at the top of the tank body. In actual irradiation, only the upper layer of catalyst can be irradiated. There are dead angles in the light source irradiation, and the catalyst may not fully participate in the reaction. The degradation rate of anesthetic waste gas needs to be further improved. Moreover, during the catalytic reaction of the waste gas, part of the gas may not fully participate in the reaction with the catalyst. If the insufficiently reacted gas directly rises and escapes, there may be a risk of secondary pollution. SUMMARY

[0004] The purpose of the present application is to solve the problems raised in the background art, and to provide an anesthetic gas purification device for clinical medicine in anesthesiology.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: Refer to Figures 1-10 A clinical anesthetic gas purification device for anesthesiology, comprising: Purification tank 1 and storage tank 201 are fixedly connected to trolley 2; A connecting pipe 101 is connected to the purification tank 1, and the connecting pipe 101 is connected to the storage tank 201. An exhaust pump 202 is also fixedly connected to the trolley 2, and the exhaust pump 202 is connected to the storage tank 201. After purification is completed, the staff pushes the cart 2 to the gas emission room, starts the exhaust pump 202 to extract the gas from the storage tank 201 and discharge it into the gas emission room.

[0022] An air distribution plate 4 with an air delivery chamber 401 is rotatably connected to the purification tank 1; The air inlet pipe 2032 is fixedly connected to the bottom of the purification tank 1, and the air inlet pipe 2032 is connected to the air delivery chamber 401. Reference Figure 8 In specific implementation, a rotary joint 7 is provided on the air intake pipe 2032, and the rotary joint 7 is connected to the air distribution plate 4. The purification tank 1 is equipped with multiple catalytic balls 8, which are located on the air distribution plate 4; Reference Figure 7 In practice, the catalyst ball 8 is a commercially available titanium dioxide / ceramic composite ball; It should be noted that the particle size of catalyst ball 8 is 3-5 nm.

[0023] Rotating ring 3 is rotatably connected to purification tank 1; Multiple sets of light strips 303 and multiple sets of light-refractive plates 301 are fixedly connected to the rotating ring 3, and multiple light beads 3031 are fixedly connected to the light strips 303; Reference Figure 5 , Figure 10 In practice, the 3031 LED chip is a commercially available UV-LED lamp.

[0024] The light strip 303 and the light-refractive plate 301 are alternately arranged on the inner wall of the rotating ring 3; The refracting plate 301 is a curved, multi-faceted refracting plate.

[0025] By setting the refracting plate 301 as a curved multi-faceted refracting plate, the refraction efficiency of ultraviolet light can be improved, thereby enhancing the diffuse reflection effect.

[0026] The exhaust gas to be purified is sent into the intake pipe 2032. The air distribution plate 4 rotates to send the exhaust gas into the purification tank 1, and at the same time blows the catalytic balls 8 on the air distribution plate 4. Multiple catalytic balls 8 are blown upward to the area of ​​the lamp strip 303 and suspended. The lamp beads 3031 on the lamp strip 303 emit ultraviolet light. Multiple catalytic balls 8 adsorb and purify the exhaust gas. The rotating ring 3 rotates to drive the lamp strip 303 to rotate and irradiate the catalytic balls 8 at different positions. At the same time, the refracting plate 301 rotates synchronously and refracts the ultraviolet light that is not irradiated on the catalytic balls 8.

[0027] An electromagnet 1042 and a first drive ring 104 are rotatably connected in the purification tank 1. The electromagnet 1042 is fixedly connected to the first drive ring 104, and the first drive ring 104 is fixedly connected to the air distribution plate 4. A second drive ring 6 is fixedly connected to the bottom of the rotating ring 3. A connecting rod 1052 is slidably connected to the second drive ring 6, and the connecting rod 1052 is attracted to the electromagnet 1042.

[0028] A limiting cavity 105 is formed in the second drive ring 6, and a limiting head 1051 is slidably connected in the limiting cavity 105. The limiting head 1051 is fixedly connected to the connecting rod 1052.

[0029] Reference Figure 6In specific implementation, the limiting head 1051 slides in the limiting cavity 105, thereby ensuring the movement stability of the connecting rod 1052 and the connection stability of the connecting rod 1052 after attracting the electromagnet 1042.

[0030] A spring 1053 is fixedly connected to the limiting head 1051, and the end of the spring 1053 away from the limiting head 1051 is fixedly connected to the inner bottom wall of the limiting cavity 105.

[0031] Reference Figure 6 In practice, when the electromagnet 1042 is de-energized, the connecting rod 1052 can quickly return to its original position and slide into the limiting cavity 105 under the elastic force of the spring 1053.

[0032] A third drive ring 102 and a fourth drive ring 103 are rotatably connected to the purification tank 1. The third drive ring 102 and the fourth drive ring 103 are fixedly connected. The end of the fourth drive ring 103 away from the third drive ring 102 is fixedly connected to the rotating ring 3. Multiple sets of turbulence blades 1021 are fixedly connected to the inner wall of the third drive ring 102.

[0033] A drive motor 5 is fixedly connected to the bottom of the purification tank 1. A drive rod 501 is fixedly connected to the drive end of the drive motor 5. A gear 5011 is fixedly connected to the top of the drive rod 501. A gear ring 402 is fixedly connected to the bottom of the air distribution plate 4. The gear 5011 meshes with the gear ring 402.

[0034] Reference Figures 1-3 In actual use, the staff pushes the trolley 2, which is loaded with the purification tank 1 and the storage tank 201, to the designated position in the anesthesiology operating room; the air pump 203 on the trolley 2 is started, and the air pump 203 draws the anesthetic waste gas generated in the operating room through the horn pipe 2031 at the air extraction end. After the waste gas is pressurized by the air pump 203, it is delivered to the air delivery chamber 401 of the air distribution plate 4 through the air inlet pipe 2032 connected to the air outlet end; and blown out through the air distribution holes on the air distribution plate 4. Reference Figures 4-8 During purification, the drive motor 5 at the bottom of the purification tank 1 is started. The drive end of the drive motor 5 drives the drive rod 501 to rotate. The gear 5011 at the top of the drive rod 501 meshes with the gear ring 402 at the bottom of the air distribution plate 4, thereby driving the air distribution plate 4 to rotate inside the purification tank 1. When the air distribution plate 4 rotates, the first drive ring 104 fixedly connected to the air distribution plate 4 rotates synchronously, and the electromagnet 1042 fixed on the first drive ring 104 rotates together with the first drive ring 104.

[0035] When the electromagnet 1042 is energized, it generates a magnetic force to attract the connecting rod 1052 on the second drive ring 6. The connecting rod 1052 drives the limiting head 1051 to compress the spring 1053 and slide out along the limiting cavity 105, realizing the linkage between the electromagnet 1042 and the second drive ring 6. Since the second drive ring 6 is fixedly connected to the rotating ring 3, the rotating ring 3 rotates synchronously with the second drive ring 6. The third drive ring 102 and the fourth drive ring 103, which are fixedly connected to the rotating ring 3, rotate synchronously. The turbulence blades 1021 on the inner sidewall of the third drive ring 102 rotate together with the third drive ring 102. When the electromagnet 1042 is de-energized, the magnetic force disappears, the connecting rod 1052 is reset and stored under the elastic force of the spring 1053, the electromagnet 1042 is disengaged from the second drive ring 6, and the rotating ring 3, the third drive ring 102, and the turbulence blade 1021 decelerate to a stop under the action of inertia. During the purification process, the control system repeatedly cycles through power-on linkage rotation and power-off disengagement to achieve intermittent rotation of the rotating ring 3 and the third drive ring 102.

[0036] When the rotating ring 3 drives the lamp strip 303 and the refracting plate 301 to rotate intermittently, it can break the inertia of the formation of the catalytic ball 8 agglomeration, so that the catalytic ball 8 can be redispersed and fluidized, ensuring the stability of the gas-solid contact area and avoiding the reduction of purification efficiency caused by agglomeration.

[0037] During the rotation of the air distribution plate 4, the anesthetic waste gas in the air delivery chamber 401 is blown upward evenly through the air distribution holes of the air distribution plate 4. The airflow drives multiple catalytic balls 8 on the air distribution plate 4 to suspend and fluidize until they rise to the area where the lamp strip 303 is located. At the same time, the rotating ring 3 drives multiple sets of lamp strips 303 and multiple sets of refracting plates 301 fixed on it to rotate synchronously. The lamp beads 3031 on the lamp strip 303 are activated and emit ultraviolet light. The rotating lamp strip 303 provides all-round dynamic irradiation to the suspended catalytic balls 8. The ultraviolet light that does not directly irradiate the catalytic balls 8 is refracted by the synchronously rotating refracting plates 301 to form scattered light covering the catalytic area, further improving the uniformity of illumination. The catalytic balls 8 fully adsorb the waste gas in the fluidized state and generate strong oxidizing free radicals under ultraviolet light excitation, which oxidize and decompose the anesthetic waste gas into harmless substances.

[0038] When the turbulence blades 1021 on the third drive ring 102 rotate, they create turbulence on the gas in the upper space of the purification tank 1, forcing the unreacted gas to flow back to the fluidization zone of the catalyst ball 8, and react with the catalyst ball 8 again to achieve deep purification.

[0039] After purification is completed, the gas purified by catalysis is transported to the storage tank 201 through the connecting pipe 101 on the purification tank 1 for temporary storage. The staff pushes the trolley 2 to the designated gas emission room, starts the exhaust pump 202 on the trolley 2, and the exhaust pump 202 extracts the purified gas temporarily stored in the storage tank 201 and discharges it to the gas emission room, thus completing the entire anesthetic gas purification process.

[0040] An air pump 203 is fixedly connected to the trolley 2. The air outlet of the air pump 203 is connected to the air inlet pipe 2032. A horn pipe 2031 is fixedly connected to the air suction end of the air pump 203.

[0041] A first sealing ring 302 is fixedly connected to the rotating ring 3, and the first sealing ring 302 is attached to the purification tank 1.

[0042] A second sealing ring 1041 is fixedly connected to the first drive ring 104, and the second sealing ring 1041 is in contact with the purification tank 1.

[0043] It should be noted that both the first sealing ring 302 and the second sealing ring 1041 are commercially available rolling sealing rings.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
