Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to an anesthetic waste gas recovery and discharge device. Background Art

[0002] The extracorporeal circulation machine is a mechanical device composed of a group of pumps that can drive blood flow in a predetermined direction and speed. It temporarily replaces the heart's pumping function during extracorporeal circulation, and also has the function of driving cardioplegia and attracting blood from the heart cavity and surgical field. The extracorporeal circulation machine is equipped with an anesthetic gas vaporizer, which is used to convert anesthetic drugs into evaporated gas. Through a certain amount of carrier gas, part of the gas carries away saturated anesthetic gas to become an airflow with a certain concentration of anesthetic vapor, so that during extracorporeal circulation, anesthetic gas can be directly blown into the membrane lung to maintain the depth of anesthesia during extracorporeal circulation. However, during the use of the extracorporeal circulation machine, the extracorporeal circulation machine directly discharges anesthetic waste into the operating room, which is not only easy to cause secondary inhalation of patients and affect the inhalation dose of anesthetics, but also easy to be inhaled by medical staff in the operating room, affecting the normal work of medical staff, and easily causing dizziness, fatigue, lack of energy and other problems in a short time. Therefore, under normal circumstances, doctors connect a relatively long exhaust pipe from the extracorporeal circulation machine to the exhaust gas outlet on the anesthesia machine, but it needs to be repeatedly plugged and unplugged each time, which is very inconvenient.

[0003] The patent with publication number CN221580171U discloses an anesthetic waste gas extraction device for anesthesia department, including a supporting base plate, a moving wheel is provided on one side of the lower end, an extraction support frame is provided on the upper end face of the supporting base plate, a collecting box, a processing box and an adsorption box are provided on the upper end of the extraction support frame, and a heating wire is provided on the lower side of the inner end face of the collecting box. When in use, by setting the heating wire and the atomizing nozzle in a corresponding state, the water flow inside the collecting box can be conveniently heated, and atomized through the atomizing nozzle to make it fully integrated with the external anesthetic waste gas, and at the same time, under the corresponding setting state of the cooling water tank, the water pipe and the condensation plate, the fused mist of the atomized water vapor and the anesthetic waste gas can be condensed to remove the anesthetic waste gas, and at the same time, under the corresponding setting state of the activated carbon filter layer, harmful substances in the anesthetic waste gas can be conveniently adsorbed.

[0004] In the above technical scheme, the anesthetic waste gas in the air in the operating room is treated. The anesthetic waste gas is treated only after it is dispersed and diffused into the operating room. The above technical scheme cannot timely treat the anesthetic waste gas generated by the anesthetic gas vaporizer on the extracorporeal circulation machine, which is easily inhaled by the medical staff in the operating room, affecting the normal work of the medical staff and having a poor use effect.

[0017] 1. The present invention provides an anesthetic waste gas recovery and discharge device that can process anesthetic waste gas generated by an extracorporeal circulation machine. The device is connected to the anesthetic waste discharge pipe port of the extracorporeal circulation machine so as to timely process the anesthetic waste gas generated by the extracorporeal circulation machine; wherein, the anesthetic waste gas recovery and discharge device includes a disinfection mechanism, a condensation and liquefaction mechanism and an adsorption mechanism, so that after the anesthetic waste gas enters the anesthetic waste gas recovery device, the anesthetic waste gas is heated and disinfected at high temperature and then condensed to realize the recovery of anesthetic components in the anesthetic waste gas, and the adsorption mechanism is used to adsorb and degrade the unliquefied anesthetic waste gas, so that the gas that has been adsorbed and degraded is safely discharged through the exhaust pipe of the adsorption mechanism.

[0026] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In addition, features stated as “first” or “second” may explicitly or implicitly include one or more of such features.

[0029] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The anesthetic waste gas recovery and discharge device provided in the embodiment of the present invention is applicable to an extracorporeal circulation machine with an anesthetic gas vaporizer. For example, the models of the extracorporeal circulation machine are WEL-1000HA2plus, Stockert S5, etc. Example 1

[0032] The embodiment of the present invention provides an anesthetic waste gas recovery and discharge device, such as Figure 1-15 As shown, it includes a box body 1, and an input pipe 2, a disinfection mechanism 3, a condensation and liquefaction mechanism 4 and an adsorption mechanism 5 arranged in the box body 1.

[0033] like Figures 1 to 8 As shown, the box body 1 is a square structure, including three processing chambers, which are a first processing chamber 11, a second processing chamber 12 and a third processing chamber 13; the first processing chamber 11 is connected to the second processing chamber 12, and the second processing chamber 12 is connected to the third processing chamber 13.

[0034] Specifically, a bracket is provided at the bottom end of the box body 1 to facilitate moving the box body 1 .

[0035] An access port is provided at the upper end of the first processing chamber 11 so that the input tube 2 can be connected to the anesthesia waste gas exhaust pipe of the extracorporeal circulation machine after passing through the access port; The input tube 2 is an L-shaped tubular structure, one end of which is connected to the access port of the first processing chamber 11, and the other end of which is connected to the disinfection mechanism 3 disposed in the first processing chamber.

[0036] Specifically, Fig. 9 and 10 As shown, a plurality of air outlet pipes 21 are arranged at equal intervals around the input pipe 2, the ends of the plurality of air outlet pipes 21 are connected to the input pipe 2, and a one-way filter 22 is provided in the input pipe 2. The one-way filter 22 is located on a side close to the end of the input pipe 2, and the one-way filter 22 is used to prevent the backflow of anesthetic waste gas. In this way, after the anesthetic waste gas passes through the one-way filter 22 from the end of the input pipe 2 and enters the first processing chamber 11, the anesthetic waste gas will not pass through the one-way filter 22 and flow back to the anesthetic waste gas discharge pipe of the extracorporeal circulation machine.

[0037] In actual application, in order to form negative pressure in the input tube 2 , a one-way filter is provided in the tube opening of the outlet tube 21 , so that the anesthetic waste gas enters the first processing chamber 11 from the input tube 2 .

[0038] The one-way filter 22 is a prior art, and the embodiment of the present invention does not improve the structure of the one-way filter 22. For example, the model of the one-way filter 22 is XFXT02-FLG, ERV150 D, etc. In practical applications, the one-way filter 22 can be replaced by a one-way valve.

[0039] like Figure 2 , 8 As shown in FIG. 10 , the disinfection mechanism 3 includes a heating rod 31 and an exhaust assembly connected to the heating rod 31, and the exhaust assembly is used to extract the anesthetic waste gas into the first processing chamber 11. The exhaust assembly includes a piston 32, a slider 22, a sliding connection 34, a rotating connecting rod 35 and a first exhaust fan 36.

[0040] Specifically, the piston 32 is located in the input tube 2 and on the side of the one-way filter 22 away from the extracorporeal circulation machine.

[0041] The sliding connection member 34 includes a crossbar and a longitudinal bar arranged perpendicular to the crossbar, wherein the crossbar is an L-shaped structure and the longitudinal bar is a straight bar. The crossbar and the longitudinal bar are connected in one piece.

[0042] Specifically, one end of the sliding connector 34 is fixedly connected to the piston 32, and the other end is fixedly connected to the longitudinal rod, wherein the end of the longitudinal rod away from the cross rod is fixedly connected to the slider 33. It should be noted that the embodiment of the present invention does not limit the fixed connection method between the sliding connector 34 and the piston 32, and the fixed connection method between the sliding connector 34 and the slider 33. For example, the fixed connection method between the sliding connector 34 and the piston 32, and the fixed connection method between the sliding connector 34 and the slider 33 are both welding.

[0043] The slider 33 is a long strip block structure.

[0044] In practical applications, the slider 33 is limitedly disposed in a sliding groove 11 a at the bottom of the first processing chamber 11 .

[0045] The rotating connecting rod 35 is a V-shaped structure, including two rotatably connected connecting rods; the movable end of one connecting rod is sleeved on the longitudinal rod of the sliding connecting member 34, and the free end of the other connecting rod is fixedly connected to the rotating shaft of the first exhaust fan 36.

[0046] The heating rod 31 is fixedly disposed on the slider 33 , and the heating rod 31 and the slider 33 are disposed perpendicular to each other.

[0047] The working principle of the disinfection mechanism 3 provided in the embodiment of the present invention is: The first exhaust fan 36 is turned on and rotated, thereby driving the rotating connecting rod 35 to rotate around the rotating shaft of the first exhaust fan 36, and the rotating connecting rod 35 drives the slider 33 to reciprocate in the slide groove 11a. At the same time, the rotating connecting rod 35 drives the sliding connection 34 to reciprocate linearly in the horizontal direction. Then, the piston 32 reciprocates in the input pipe 2 with the sliding connection 34 to draw the anesthetic waste gas in the anesthetic waste gas exhaust pipe of the extracorporeal circulation machine into the input pipe 2, and then squeeze the anesthetic waste gas from the air inlet pipe 21 to the first exhaust fan 36. In the processing chamber 11, that is, when the piston 32 moves to the side away from the access port of the input tube 2, the anesthetic waste gas enters the input tube 2 from the anesthetic waste gas exhaust pipe of the extracorporeal circulation machine; when the piston 32 moves to the side close to the access port of the input tube 2, the anesthetic waste gas moves to the port of the gas outlet pipe 21, and then enters the first processing chamber 11. At the same time, the heating rod 31 arranged on the slider 33 reciprocates in the horizontal direction with the slider 33 to perform high-temperature disinfection on the anesthetic waste gas in the first processing chamber 11, thereby realizing one-time treatment of the anesthetic waste gas; The anesthetic waste gas that has been subjected to high-temperature disinfection treatment is then extracted by the first exhaust fan 36 to the condensation and liquefaction mechanism 4 located in the second processing chamber 12 so as to perform secondary treatment on the anesthetic waste gas.

[0048] like Fig.11 As shown, the condensation and liquefaction mechanism 4 includes a gas delivery pipe 41 , a double-layer sleeve 42 , a connecting tube 43 and a condensate tank 44 .

[0049] The connecting tube 43 is a cylindrical structure, and the connecting tube 43 is fixedly arranged on the bottom end of the first exhaust fan 36. The connecting tube 43 is connected to the bottom of the first processing chamber 11.

[0050] After the front end of the air delivery pipe 41 passes through the connecting tube 43 , the front end thereof is located below the first exhaust fan 36 , and the end of the air delivery pipe 41 is connected to the double-layer sleeve 42 .

[0051] The double-layer sleeve 42 includes an outer layer sleeve 42a and an inner layer sleeve 42b. The inner layer sleeve 42a contains condensate for condensing and liquefying the anesthetic waste gas.

[0052] Specifically, the inner tube 42a is an S-shaped continuous curved tube, one end of which is connected to the infusion tube of the condensate tank 44, and the other end is connected to the outlet tube of the condensate tank 44. In this way, the condensate flows out from the infusion tube of the condensate tank 44 to the inner tube 42a, and then flows back from the inner tube 42a to the condensate tank 44 through the outlet tube, thereby realizing the recycling of the condensate.

[0053] The front end of the outer tube 42a is connected to the air supply pipe 41, and an opening is provided at the end of the outer tube 42a so that the anesthetic waste gas that has been sterilized by high temperature can enter the gap between the outer tube 42a and the inner tube 42a, and then enter the second processing chamber 12 from the opening at the end of the outer tube 4.

[0054] Correspondingly, in order to facilitate the recovery of the condensed anesthetic gas, a discharge pipe 45 is provided at the open lower end of the outer tube 42a, and the lower end of the discharge pipe 45 is located in a groove on the inner bottom surface of the second processing chamber 12. In this way, the anesthetic waste gas flows out from the discharge pipe 45 after condensation, and then passes through the groove into the recovery device located below the box body 1.

[0055] In actual use, in order to facilitate the condensation and liquefaction of the anesthetic waste liquid, it flows out from the discharge pipe 45 and then passes through the groove into the recovery device located below the box body 1 so as to collect the liquefied anesthetic waste liquid.

[0056] In addition, in order to facilitate the condensed anesthetic waste liquid to flow out of the gap between the outer layer cylinder 42a and the inner layer cylinder 42a, the outer layer cylinder 42a is also connected to the output end of the rotary motor; wherein the rotary motor is embedded in the partition between the third processing chamber 13 and the second processing chamber 12, and the rotary motor extends out of the partition and is fixedly connected to the outer surface of the outer layer cylinder 42a. In actual use, the inclination angle of the outer layer cylinder 42a can be adjusted by the rotary motor so that the condensed and liquefied anesthetic waste liquid flows out from the opening of the outer layer cylinder 42a. Specifically, an outflow hole is provided at the turning point of the outer layer cylinder 42a so that the anesthetic waste liquid can drip into the groove on the ground of the second processing chamber 12.

[0057] It should be noted that the rotating electrical machine provided in the embodiment of the present invention is the prior art, and the embodiment of the present invention improves upon it.

[0058] The uncondensed and liquefied anesthetic waste gas enters the second air inlet of the adsorption mechanism 5 located in the third treatment chamber 13 from the air outlet of the second treatment chamber 12, that is, the first air inlet of the third treatment chamber 13, so as to perform adsorption treatment on the uncondensed and liquefied anesthetic waste gas.

[0059] It should be noted that the recovery device in the embodiment of the present invention is a prior art, and the embodiment of the present invention does not improve it. For example, the recovery device is a bucket.

[0060] like Figures 12 to 15 As shown, the adsorption mechanism 5 includes an adsorption box 51 and a vertical partition 52 disposed in the adsorption box 51, so that the vertical partition 52 divides the internal space of the adsorption chamber 51 into an adsorption chamber 51a and a degradation chamber 51b; specifically, a second air inlet is provided at an upper position of the side wall of the adsorption box 51, and the second air inlet is connected to the first air inlet provided on the inner wall of the third processing chamber 13. The vertical partition 52 is provided with a plurality of through holes arranged at equal intervals so that the anesthetic waste gas can pass through.

[0061] An adsorption material for adsorbing anesthetic waste gas is placed in the adsorption chamber 51a. For example, the adsorption material is activated carbon.

[0062] Degradation materials for degrading anesthetic components in the anesthetic gas are placed in the degradation chamber 51b. For example, the degradation materials are carbon dioxide adsorbents.

[0063] In practical applications, activated carbon can adsorb and remove volatile anesthetics and other harmful gases in anesthetic waste gas. CO2 adsorbent can degrade halothane and sevoflurane in anesthetic waste gas into halogenated olefins. Example 2

[0064] Based on Example 1, different from Example 1, Fig.13 As shown, in order to fully absorb and degrade the uncondensed and liquefied anesthetic waste gas, the adsorption box 51 provided in the embodiment of the present invention is also provided with a second exhaust fan 53, a one-way blocking member 54 and a transverse partition 55.

[0065] The second exhaust fan 53 is disposed in the second air inlet of the adsorption box 51 so as to draw the uncondensed and liquefied anesthetic waste gas in the second processing chamber 12 into the third processing chamber 13 so as to adsorb and degrade the anesthetic waste gas.

[0066] The one-way blocking piece 54 is arranged in the pipe mouth of the exhaust pipe of the adsorption box 51, so that the anesthetic waste gas can be gathered in the adsorption box 51, so as to fully adsorb and degrade the anesthetic waste gas until the pressure in the adsorption box 1 increases, and the one-way blocking piece 54 is reopened, so that the fully adsorbed and degraded gas can be safely discharged from the exhaust pipe of the adsorption box 51.

[0067] The one-way blocking member 54 includes a spring 54a, a blocking ball 54b and a fixing ring 54c.

[0068] Specifically, the blocking ball 54b is disposed at the end of the spring 54a; One end of the spring 54a away from the blocking ball 54b is connected to the fixing ring 54c; The side edge of the fixing ring 54 is fixedly connected to the inner wall of the exhaust pipe of the adsorption box 51 .

[0069] In order to further adsorb and degrade the anesthetic waste gas, a plurality of transverse partitions 55 are provided in the adsorption box 51. The plurality of transverse partitions 55 are fixedly connected to the vertical partition 53, and one end of the plurality of transverse partitions 55 is connected to the inner wall of the adsorption box 51, and the other end is located on the side of the vertical partition 53 and is not connected to the inner wall of the adsorption box 51. In this way, the plurality of transverse partitions 55 form an S-shaped channel in the adsorption box 51, so that the anesthetic waste gas repeatedly passes through the adsorption chamber 51a and the degradation chamber 51b, so that the anesthetic waste gas is fully adsorbed and degraded, and the anesthetic waste gas after being fully adsorbed and degraded is safely discharged through the exhaust pipe of the adsorption box 51. Example 3

[0070] Based on Example 1, what is different from Examples 1 and 2 is that Figure 2 As shown, the disinfection mechanism 3 provided in the embodiment of the present invention further includes an ultraviolet irradiation lamp 37. Specifically, the ultraviolet irradiation lamp 37 is fixedly arranged on the inner wall of the first processing chamber 11.

[0071] When in use, the ultraviolet irradiation lamp 37 can be used to perform ultraviolet disinfection on the anesthetic waste gas in the first processing chamber 11, thereby further improving the disinfection effect on the anesthetic waste gas.

[0072] Application examples: Step 1: Move the box 1 to the port of the anesthetic waste gas discharge pipe of the extracorporeal circulation machine; Step 2: Connect the input tube 2 to the outlet of the anesthetic waste gas discharge pipe of the extracorporeal circulation machine; Step 3: Turn on the first exhaust fan 36 to rotate the first exhaust fan 36. When the first exhaust fan 36 rotates, the first exhaust fan 36 drives the rotating connecting rod 35 to rotate; then the rotating connecting rod 35 drives the slider 33 to reciprocate in the slide groove 11a, so that the heating rod 31 on the slider 33 reciprocates, and at the same time, the rotating connecting rod 35 drives the sliding connection 34 to reciprocate linearly; when the sliding connection 34 moves, it drives the piston 32 to reciprocate, so that the anesthetic waste gas passes through the one-way filter 22, and then passes through the air inlet pipe 21, and finally enters the first processing chamber 11, so that the anesthetic waste gas is heated and disinfected by the heating rod 31 at high temperature, so as to achieve one-time treatment of the anesthetic waste gas; Step 4: After passing through the first exhaust fan 36, the anesthetic waste gas enters the air delivery pipe 41 of the condensation and liquefaction mechanism 4; Step 5: After passing through the gas delivery pipe 41, the waste anesthetic gas enters the gap between the inner layer tube 42a and the outer layer tube 42b, so that the outer surface of the inner layer tube 42a filled with condensate condenses and liquefies the waste anesthetic gas, thereby realizing secondary treatment of the waste anesthetic gas; In this step, the condensed and liquefied anesthetic gas flows out from the opening of the outer tube 42b to the discharge pipe 45, and then enters the groove on the inner bottom surface of the second treatment chamber 12 through the discharge pipe 45, or directly flows out from the outflow port of the outer tube 42a to the groove on the bottom surface of the second treatment chamber 12, and then enters the recovery device arranged below the box body 1 through the groove; The uncondensed and liquefied anesthetic gas passes through the gap between the inner tube 42a and the outer tube 42b and enters the second processing chamber 12; Step 6: The second exhaust fan 53 draws the anesthetic waste gas in the second processing chamber 12 into the adsorption chamber 51, and the anesthetic waste gas repeatedly passes through the adsorption chamber 51a and the degradation chamber 51b so as to fully adsorb and degrade the anesthetic waste gas; In this step, the one-way sealing member 54 gathers the anesthetic waste gas in the adsorption box 51 to improve the adsorption and degradation effect of the anesthetic waste gas until the air pressure in the adsorption box 51 increases, so that the sealing ball 54b is flushed into the exhaust pipe of the adsorption box 51, so that the sealing ball 54b no longer blocks the exhaust pipe opening of the adsorption box 51, thereby allowing the anesthetic waste gas that has been fully adsorbed and degraded to be safely discharged.
