Description

Technical Field

[0001] The invention relates to the technical field of anesthesia devices, in particular to an anesthesia device with adjustable concentration. Background Art

[0002] The anesthesia concentration regulating anesthesia device is a device used in the medical field to accurately control the concentration of anesthetics. It is crucial to ensure the safety of patients during surgery. Through a precise gas mixing system, oxygen and anesthetic gases are mixed in a certain proportion for patients to inhale. The flow control valve is used to adjust the flow of the mixed gas to ensure that the concentration of anesthetic gas inhaled by the patient is constant. It includes a gas supply system, a flow control system, an evaporator, a main unit (including a gas concentration sensor, a pressure sensor, a flow sensor, etc.), a microprocessor, a display screen, a ventilator, etc.

[0003] For example, the patent publication number published on the China Patent Network is: CN 111991665 B, and the patent name is: A concentration-adjustable anesthesia device for the Department of Anesthesiology, including a fixed storage device, an anesthesia atomization device, an anesthesia increasing device, and an oxygen storage device. The fixed storage device can store items needed during surgery and is also the installation platform for each device. The anesthesia atomization device can be operated to atomize the anesthetic through the anesthesia atomization bottle. The anesthesia increasing device can automatically increase the amount of anesthetic by rotating the motor to adjust the concentration of the anesthetic. The oxygen storage device can be operated to adjust the input amount of oxygen during surgery by rotating the increase knob.

[0004] However, existing concentration-regulated anesthesia devices mainly control the release amount of anesthetic gas by adjusting the power of the nebulizer. In low-flow inhalation anesthesia, there may be accumulation of gases other than anesthetic gas in the loop, such as accumulation of carbon dioxide and accumulation of metabolites of inhaled anesthetic drugs (such as complex A). When there are multiple gases in the loop, they will mix with each other, thereby affecting their respective concentrations in the loop and the patient's body. In particular, when the concentration of non-anesthetic gas is high, the concentration of anesthetic gas will be diluted, resulting in a weakened anesthetic effect.

[0005] Some anesthesia equipment performs closed-loop treatment of exhaled gas by installing a tank containing soda lime. Although this method can absorb carbon dioxide and moisture in the exhaled gas to a certain extent, the soda lime accumulates directly inside the tank, and the contact area with the exhaled gas is relatively small, resulting in the inability to fully absorb the carbon dioxide and moisture in the exhaled gas, thereby affecting the absorption efficiency. The exhaled gas that is not fully absorbed directly enters the mixing chamber, which will have an impact on the drug concentration, resulting in inaccurate control of the anesthetic gas concentration, and further affecting the anesthesia effect. Due to the low utilization rate of soda lime and incomplete reaction, the soda lime in the tank may quickly reach saturation, and the soda lime tank needs to be replaced frequently, thereby increasing maintenance costs.

[0006] Therefore, it is necessary to design and create an anesthetic device with adjustable concentration. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides a concentration-adjustable anesthesia device, comprising a body 1; An atomizer 2 connected to the surface of the body 1; An anesthetic drug tank 3 connected to the surface of the atomizer 2; A filter assembly 44 independently disposed inside the housing 1; One side of the top of the body 1 is connected to a reaction chamber 4, the nebulizer 2 can extract and atomize the medicine inside the anesthetic drug tank 3 and inject it into the interior of the reaction chamber 4 through the output end, the top of the reaction chamber 4 is connected to an oxygen supply pipe 5, and the other side of the reaction chamber 4 is connected to an input pipe 6 for anesthetizing the patient, and a recovery structure 7 connected to the filter component 44 is provided at the bottom of the body 1, and the front of the recovery structure 7 is connected to a reflux pipe 8 connected to the input pipe 6. The anesthetic gas output from the input pipe 6 to the patient's body forms accumulated gas after being exhaled by the patient and enters the interior of the reflux pipe 8.

[0032] refer to Figure 4The processing tank 9 is the core container of the entire recycling structure 7. It is located at the bottom of the body 1 and is interconnected with the filter component 44 inside the body 1. The material of the processing tank 9 is a corrosion-resistant, high-strength alloy material to ensure that it can withstand the pressure of internal chemical reactions and gas flow for a long time. Inside the processing tank 9, a bearing plate 10 is set. This bearing plate 10 plays a supporting and partitioning role. It divides the internal space of the processing tank 9 into two layers, the upper space is used to fill the soda lime material 12, and the lower space is used as a gas circulation channel. The material of the bearing plate 10 also needs to have good corrosion resistance and load-bearing capacity to ensure that it can maintain the stability and integrity of the structure during long-term use. The circulation component 11 is a key component in the recycling structure 7. It is located above the bearing plate 10 and is covered with soda lime material 1 2, the circulation component 11 is composed of a series of rotating parts, such as spiral conveying blades 14, which are driven by the transmission structure to rotate inside the treatment tank 9, thereby realizing the circulation of the soda lime material 12. This circulation method not only increases the contact area and contact time between the soda lime material 12 and the accumulated gas, but also ensures that the soda lime material 12 can be evenly distributed inside the treatment tank 9, further improving the gas purification efficiency. The soda lime material 12 is another key component of the recovery structure 7. It has good hygroscopicity and chemical stability, and can react chemically with the carbon dioxide component in the accumulated gas, thereby converting it into harmless substances. Inside the treatment tank 9, the soda lime material 12 is evenly filled above the carrier plate 10 and wrapped on the surface of the circulation component 11. As the circulation component 11 rotates, the soda lime material 12 can continuously contact and react with the accumulated gas, thereby realizing effective gas purification.

[0033] As a technical optimization scheme of the present invention, by setting up the treatment tank 9 and the circulation component 11, the soda lime material 12 can be circulated and transported, thereby improving the contact uniformity between the soda lime material 12 and the accumulated gas, thereby more effectively absorbing the exhaled anesthetic gas, reducing environmental pollution and saving resources.

[0034] refer to Figure 4The circulation component 11 includes a shaft 13 movably connected to the bottom of the inner wall of the treatment tank 9 through a bearing, and the transmission structure can drive the shaft 13 to rotate. The top of the shaft 13 passes through the carrier plate 10 and extends to the top of the carrier plate 10. There is a gap between the shaft 13 and the carrier plate 10 for the accumulated gas injected by the reflux pipe 8 to flow. The surface of the shaft 13 is fixedly connected to a spiral conveying blade 14 located at the top of the carrier plate 10. A sleeve 15 is provided inside the treatment tank 9 and is sleeved on the surface of the spiral conveying blade 14. The outer surface of the spiral conveying blade 14 contacts the inner wall of the sleeve 15. A bracket 16 is fixedly connected to the top of the sleeve 15. The side of the bracket 16 away from the sleeve 15 is fixedly connected to the inner wall of the treatment tank 9. The soda lime material 12 is evenly filled between the sleeve 15 and the treatment tank 9 and can be lifted upward inside the sleeve 15 during the rotation of the spiral conveying blade 14.

[0035] As a technical optimization scheme of the present invention, the circulation component 11 is driven to rotate through the transmission structure, and the circulation of the soda lime material 12 is realized, which can significantly improve the contact uniformity between the soda lime material 12 and the accumulated gas injected into the reflux pipe 8. The improvement of this contact uniformity not only helps to accelerate the rate of chemical reaction, but also ensures that the carbon dioxide in the accumulated gas can be fully absorbed and converted. Therefore, this design in the recovery structure 7 is of great significance for improving the overall performance and efficiency of the anesthesia device. Through the cooperation of the spiral conveying blade 14 and the sleeve 15, the circulation lifting and falling of the soda lime material 12 is realized, the contact area and time between the soda lime material 12 and the accumulated gas are increased, and the absorption efficiency is improved.

[0036] refer to Figure 6 The transmission structure includes a transmission motor 17 fixedly connected to the back of the processing tank 9, and a worm 18 is fixedly connected to the output end of the transmission motor 17. The end of the worm 18 away from the transmission motor 17 penetrates the processing tank 9 and extends to the inside of the processing tank 9. The surface of the shaft 13 is fixedly connected to a worm wheel 19 located on one side of the worm 18. The worm wheel 19 and the worm 18 are meshed with each other. The transmission motor 17 can use the worm 18 to drive the shaft 13 connected to the worm wheel 19 to rotate.

[0037] As a technical optimization solution of the present invention, the shaft 13 is driven to rotate by the worm 18 and the worm wheel 19, providing a stable power source for the circulation component 11, thereby ensuring the continuous circulation of the soda lime material 12.

[0038] refer to Figure 6The interior of the treatment tank 9 is provided with an intermittent circulation structure 20 through a linkage structure. The intermittent circulation structure 20 includes a support frame 21 fixedly connected to the bottom of the carrier plate 10 and sleeved on the surface of the shaft rod 13. Both sides of the support frame 21 are arranged to be inclined to expand outward. Both sides of the inner wall of the treatment tank 9 are fixedly connected with guide rods 22 located on the outside of the shaft rod 13. Both sides of the surface of the guide rod 22 are sleeved with screw sleeves 23. The top of the screw sleeve 23 is fixedly connected with a vertical plate 24. The inner side of the vertical plate 24 is fixedly connected with an extrusion rod 25. The extrusion rod 25 is located at the bottom of the support frame 21 and is connected to the support frame 21. The sliding connection and the linkage structure can utilize the torsion of the shaft 13 to push the screw sleeve 23 to move toward each other. When the screw sleeve 23 utilizes the vertical plate 24 to carry the extrusion rod 25 to move outward and the extrusion rod 25 moves to the inclined parts on both sides of the support frame 21, the support frame 21 is released from the compressed state and carries the supporting plate 10 to move vertically downward and make the top of the supporting plate 10 out of contact with the bottom of the sleeve 15. The soda lime material 12 accumulated on the top of the supporting plate 10 can roll between the sleeve 15 and the supporting plate 10 and be lifted to the inside of the sleeve 15 and contact the spiral conveying blade 14 when the supporting plate 10 rises.

[0039] As a technical optimization solution of the present invention, through the cooperation of the support frame 21, the screw sleeve 23, the vertical plate 24 and the extrusion rod 25, the intermittent up and down movement of the supporting plate 10 and the soda lime material 12 is achieved, further improving the contact uniformity between the soda lime material 12 and the accumulated gas.

[0040] refer to Figure 4 A conical ring 26 is fixedly connected to the top of the bearing plate 10 , and the inner surface of the conical ring 26 is arranged to be inclined. The soda lime material 12 can roll toward the side close to the sleeve 15 under the guidance of the inclined portion of the inner wall of the conical ring 26 .

[0041] As a technical optimization solution of the present invention, the conical ring 26 is provided to enable the soda lime material 12 to roll toward the side close to the sleeve 15 under the guidance of the inclined portion of its inner wall, which is beneficial to the uniform distribution and effective utilization of the soda lime material 12.

[0042] refer to Figure 8 The linkage structure includes a first bevel gear 27 fixedly connected to the surface of the shaft 13. Reciprocating screws 28 are movably connected to both sides of the inner wall of the processing tank 9 through bearings. The end of the reciprocating screw 28 away from the processing tank 9 passes through the screw sleeve 23 and extends to the inner side of the screw sleeve 23. The screw sleeve 23 is threadedly connected to the reciprocating screw 28. The inner end of the reciprocating screw 28 is fixedly connected to the second bevel gear 29 located on both sides of the first bevel gear 27. The second bevel gear 29 is meshed with the first bevel gear 27.

[0043] As a technical optimization solution of the present invention, through the meshing of the first bevel gear 27 and the second bevel gear 29, the function of driving the reciprocating screw 28 to rotate when the shaft 13 rotates, and then pushing the screw sleeve 23 to move, is achieved, providing a power source for the intermittent circulation structure 20.

[0044] refer to Figure 5 The side of the return pipe 8 close to the treatment tank 9 is connected to an air supply barrier structure 30 located inside the treatment tank 9. The air supply barrier structure 30 includes a connecting pipe 31 connected to one end of the return pipe 8 located inside the treatment tank 9. A connecting pipe 32 is fixedly connected between the supporting plate 10 and the supporting frame 21. The interior of the connecting pipe 32 is connected to the gap at the place where the supporting plate 10 and the shaft rod 13 pass through. The surface of the connecting pipe 32 is connected to a lifting pipe 33. The lifting pipe 33 extends to the interior of the connecting pipe 31 away from one end of the connecting pipe 32. The surface of the lifting pipe 33 is provided with a through hole 34 that is interconnected with the return pipe 8. When the supporting plate 10 moves downward following the intermittent circulation structure 20, the supporting plate 10 can carry the lifting pipe 33 to move synchronously and make it slide inside the connecting pipe 31. During the sliding process of the lifting pipe 33, the through hole 34 on its surface can be misaligned with the return pipe 8 and block the accumulated gas.

[0045] As a technical optimization solution of the present invention, by setting the lifting tube 33 and the through hole 34, the accumulated gas can be blocked and buffered when the supporting plate 10 moves up and down, avoiding the waste and poor effect caused by the accumulated gas directly impacting the soda lime material 12.

[0046] refer to Figure 6 The top end of the shaft 13 passes through the sleeve 15 and extends to the top of the sleeve 15. The top end of the shaft 13 is fixedly connected to the impeller 35 located inside the processing tank 9. The shaft 13 can drive the impeller 35 to rotate synchronously and guide the airflow inside the processing tank 9. The accumulated gas processed by the recovery structure 7 can be pressurized by the impeller 35 to enter the interior of the filter assembly 44.

[0047] As a technical optimization solution of the present invention, the impeller 35 can guide the airflow inside the treatment tank 9 so that the accumulated gas is more evenly distributed in the soda lime material 12, thereby improving the absorption efficiency. At the same time, the pressurized accumulated gas can avoid backflow after entering the interior of the filter component 44.

[0048] refer to Figure 1, both sides of the bottom of the body 1 are fixedly connected with a frame 36, the frame 36 is located on both sides of the processing tank 9, and both ends of the processing tank 9 are fixedly connected with an adjusting rod 37 located inside the frame 36. The processing tank 9 can be swung and tilted inside the frame 36 through the adjusting rod 37 and the soda lime material 12 inside can be dumped. An electric telescopic rod 38 is fixedly connected to one side of the bottom of the body 1, and a tooth plate 39 is fixedly connected to the output end of the electric telescopic rod 38. The end of the adjusting rod 37 away from the processing tank 9 is fixedly connected with a driven wheel 40, and the driven wheel 40 corresponds to the tooth plate 39 and the tooth plate 39 can utilize the surface The teeth drive the gear to rotate, and an extension plate 41 is fixedly connected to one side of the frame 36. The side of the extension plate 41 away from the frame 36 extends to the bottom of the driven wheel 40 through the left side of the driven wheel 40 and is movably connected to a knocking rod 42 through a pin shaft. The outer surface of the knocking rod 42 contacts the surface of the treatment tank 9, and the surface of the knocking rod 42 is fixedly connected to a force-bearing rod 43 located at the bottom of the tooth plate 39. The force-bearing rod 43 and the tooth plate 39 are perpendicular to each other. When the tooth plate 39 follows the electric telescopic rod 38 to descend, the inclined teeth on the surface of the tooth plate 39 can squeeze the force-bearing rod 43 and make the force-bearing rod 43 carry the knocking rod 42 to swing around the pin shaft as the axis.

[0049] As a technical optimization scheme of the present invention, the setting of the frame 36 and the adjusting rod 37 enables the processing tank 9 to be conveniently swung and tilted, so as to facilitate dumping of the internal soda lime material 12 for replacement or maintenance. The cooperation of the electric telescopic rod 38 and the toothed plate 39 can realize the swinging and tilting of the processing tank 9 by pushing the driven wheel 40 to rotate, providing a convenient operation method for replacing the soda lime material 12. The setting of the extension plate 41 and the knocking rod 42 can knock on the processing tank 9 through the cooperation of the force-bearing rod 43 and the knocking rod 42 when the electric telescopic rod 38 descends, so as to help the internal soda lime material 12 fall more loosely, which is convenient for dumping and replacement.

[0050] The working principle and use process of the present invention are as follows: anesthetic drugs are extracted and atomized from the anesthetic drug tank 3 by the nebulizer 2, and then the atomized anesthetic drugs are injected into the reaction chamber 4 of the body 1. At the same time, the oxygen supply pipe 5 provides oxygen to the reaction chamber 4, which is mixed with the atomized anesthetic drugs to form anesthetic gas. The mixed anesthetic gas is transported to the patient's body through the input pipe 6 for anesthesia. The anesthetic gas exhaled by the patient, that is, the accumulated gas, is guided to the recovery structure 7 of the body 1 through the reflux pipe 8. The recovery structure 7 is mainly composed of a processing tank 9. Inside the processing tank 9, a supporting plate 10 supports a soda lime material 12. These materials are used to absorb harmful components in the accumulated gas. In order to enhance the contact uniformity between the soda lime material 12 and the accumulated gas, a circulation component 11 is installed inside the processing tank 9. The circulation component 11 is composed of a shaft 13 and a spiral conveying blade 14. The shaft 13 is driven to rotate through a transmission structure. The rotation of the shaft 13 drives the spiral conveying blade 14 to rotate inside the treatment tank 9, thereby lifting the bottom layer of soda lime material 12 to the top of the sleeve 15, and then allowing it to freely fall into the treatment tank 9 to form an upper layer of soda lime material 12. In this way, the soda lime material 12 can be recycled, and when the accumulated gas follows the surface of the spiral conveying blade 14 to spiral upward, it is in uniform contact with the soda lime material 12, effectively absorbing the carbon dioxide component therein. An intermittent circulation structure 20 is also provided inside the treatment tank 9, which consists of The support frame 21, the guide rod 22, the screw sleeve 23, the vertical plate 24 and the extrusion rod 25 are composed of the following components. When the shaft 13 rotates, the reciprocating screw 28 is driven to rotate through the linkage structure, thereby pushing the screw sleeve 23 to move on the guide rod 22. The movement of the screw sleeve 23 drives the vertical plate 24 and the extrusion rod 25 to move outward. When the extrusion rod 25 moves to the inclined parts on both sides of the support frame 21, the support frame 21 is released from the compressed state and carries the carrying plate 10 to move vertically downward. At this time, the top of the carrying plate 10 is released from contact with the bottom of the sleeve 15. The soda lime material 12 accumulated on the top of the carrier plate 10 can roll between the sleeve 15 and the carrier plate 10 through the conical ring 26, and be lifted to the inside of the sleeve 15 and contact the spiral conveying blade 14 when the carrier plate 10 rises. In this way, the soda lime material 12 can be more evenly distributed inside the processing tank 9, thereby improving the absorption efficiency. At the same time, in order to further process the accumulated gas, a gas supply barrier structure 30 is also provided inside the processing tank 9, which is composed of a connecting pipe 31, a connecting pipe 32, and a lifting pipe. 33 and through holes 34, when the carrying plate 10 moves downward following the intermittent circulation structure 20, the lifting tube 33 is carried and moved synchronously and made to slide inside the connecting tube 31. During the sliding process of the lifting tube 33, the through holes 34 on the surface of the lifting tube 33 can be misaligned with the return pipe 8, thereby blocking and buffering the accumulated gas, and preventing the accumulated gas from directly leaking to between the sleeve 15 and the processing tank 9 through the gap separated between the sleeve 15 and the carrying plate 10. In addition, the top of the shaft 13 is also fixedly connected to the impeller 35.When the shaft 13 rotates, it can drive the impeller 35 to rotate synchronously and guide the airflow inside the treatment tank 9, which is helpful for the accumulated gas to fully contact and absorb the soda lime material 12. The gas inside the treatment tank 9 can be guided, and the reflux pipe 8 accelerates the extraction speed of the accumulated gas exhaled after anesthesia in the patient's body, so that the accumulated gas flows to the inside of the treatment tank 9 and contacts with the soda lime material 12, thereby reducing the impact of the accumulated gas on the concentration of the anesthetic gas inside the input pipe 6. The accumulated gas through the soda lime material 12 is guided into the inside of the body 1 through the treatment tank 9. The inside of the body 1 is provided with a filter component 44. The filter component 44 is a filter device and material installed inside the body 1 in the prior art (mainly composed of activated carbon adsorption and photolysis). Equipment composition), the accumulated gas treated by the filter assembly 44 is filtered and discharged into the environment. When the soda lime material 12 in the treatment tank 9 needs to be replaced after being used for a period of time, the treatment tank 9 can be swung and tilted through the frame 36 and the adjustment rod 37 at the bottom of the body 1, and the soda lime material 12 inside can be dumped out. At this time, the electric telescopic rod 38 drives the tooth plate 39 to descend, and the teeth on the surface of the tooth plate 39 drive the driven wheel 40 to rotate, thereby driving the treatment tank 9 to swing and tilt inside the frame 36. At the same time, the extension plate 41 and the knocking rod 42 on one side of the frame 36 also play an auxiliary role. When the tooth plate 39 descends, the force rod 43 is squeezed and the knocking rod 42 is swung around the pin shaft as the axis, knocking the surface of the treatment tank 9 to assist in dumping.

[0051] In summary, the concentration-adjustable anesthesia device realizes the effective delivery and recovery of anesthesia gas through the coordinated work of the components such as the atomizer 2, the reaction chamber 4, the input tube 6, the reflux tube 8 and the recovery structure 7. At the same time, through the innovative designs such as the circulation component 11, the intermittent circulation structure 20 and the gas supply barrier structure 30, the contact uniformity and absorption efficiency between the soda lime material 12 and the accumulated gas are improved, providing a safer, more reliable and efficient solution for the anesthesia process.
