Description

Technical Field

[0001] The present invention relates to the field of anesthesia technology, in particular to a concentration-adjusting anesthesia device. Background Art

[0002] Anesthesia devices are an important combination of equipment used to implement anesthesia operations in the medical field. Common anesthesia devices include inhalation anesthesia devices, which provide anesthesia to patients by precisely controlling the delivery and concentration of anesthetic gases; and intravenous anesthesia infusion devices, which can accurately adjust the infusion rate and dosage of anesthetic drugs; in addition, compound anesthesia devices combine the advantages of inhalation and intravenous anesthesia, and can flexibly adjust the anesthesia method according to different needs to ensure safe and efficient surgery.

[0003] Among them, inhalation anesthesia devices are crucial in the field of medical anesthesia. They deliver the right amount of gas, such as isoflurane, to the patient's respiratory system by precisely controlling the delivery of anesthetic gases. They usually include a gas supply module, a concentration adjustment component, and a breathing circuit. The device can monitor the patient's breathing condition and gas concentration in real time. It effectively reduces anesthesia risks and ensures smooth surgery, and is an indispensable part of modern medicine.

[0004] In the current medical environment, due to the different tolerance of different patients to anesthetic drugs, a fixed anesthetic concentration may cause insufficient anesthesia for some patients, resulting in pain and discomfort during surgery, affecting surgical operations; while for other patients, it may cause excessive anesthesia, causing serious complications and threatening life safety.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the concentration-regulated anesthesia device, the rotation frequency of the regulating component is adjusted by the breathing frequency of different patients during the operation, so that the regulating component adjusts the flow of the anesthetic gas and transports it to the inside of the mixing component. The oxygen and the anesthetic gas are mixed through the mixing component to adjust the anesthetic gas of different concentrations.

[0016] 2. In the concentration-regulated anesthesia device, the mixing component rotates continuously. When there is no anesthetic gas input, oxygen will be continuously transported to increase the flow rate of oxygen, improve blood oxygen saturation, and maintain the normal function of important organs. At the same time, the mixing component can also heat the anesthetic gas and oxygen during rotation, reduce the evaporation of moisture from the respiratory mucosa, keep the mucosa moist, and reduce the risk of mucosal damage and inflammation.

[0017] 3. In the concentration-regulated anesthesia device, when the patient breathes rapidly, the body's breathing rate speeds up and the breathing depth increases, which increases the amount of gas exhaled per unit time, thereby driving the rotation frequency of the regulating component to speed up, making it easier to deliver more anesthetic gas into the mixing component to mix with oxygen, thereby making it easier for the patient to ingest anesthetic gas with a higher concentration to quickly achieve and maintain an appropriate anesthesia effect in response to faster gas exchange and body metabolism.

[0018] 4. In the concentration-regulated anesthesia device, when the patient breathes weakly, the body's breathing becomes shallow and slow, and the amount of gas discharged from the lungs during each breath decreases, resulting in a significant decrease in the exhaled gas flow rate per unit time, thereby driving the rotation frequency of the regulating component to weaken, and delivering less anesthetic gas into the mixing component, making the anesthetic concentration lighter, avoiding relatively slow drug metabolism during weak breathing. The use of high-concentration anesthesia may lead to drug accumulation and increased side effects, so lower concentration anesthesia helps to reduce risks while ensuring the anesthetic effect.

Example

[0023] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the present embodiment aims to provide a concentration-adjustable anesthesia device, including an anesthesia machine 1, in which an oxygen supply device and an anesthesia gas supply device are provided, a support 11 is fixedly connected to the anesthesia machine 1, a support block 110 is fixedly connected to the outer wall of the support 11, a support ring 111 is fixedly connected to the outer wall of the support block 110, an adjustment component 12 is fixedly connected to the top of the support 11, and a mixing component 13 is fixedly connected to the outer wall of one end of the adjustment component 12; The outer wall of the other end of the regulating component 12 is fixedly connected to the anesthesia trachea 2, the outer wall of the mixing component 13 is fixedly connected to the oxygen tube 3, the end of the anesthesia trachea 2 is fixedly connected to the anesthesia gas supply device, the end of the oxygen tube 3 is fixedly connected to the oxygen supply device, the end of the regulating component 12 is fixedly connected to the exhalation tube 5, the end of the mixing component 13 is fixedly connected to the inhalation tube 4, the ends of the inhalation tube 4 and the exhalation tube 5 are fixedly connected to the one-way valve 61, and the breathing mask 6 is fixedly connected between the ends of the two one-way valves 61; The regulating component 12 is used to adjust the anesthetic dose according to the strength of the exhalation frequency. The overall conical design of the mixing component 13 can increase the mixing time of the anesthetic gas and the oxygen. The mixing component 13 is used to mix the anesthetic gas and the oxygen and accelerate the delivery flow rate of the oxygen. The improvement of this embodiment is that the rotation frequency of the regulating component 12 is adjusted according to the breathing frequency of different patients during the operation, so that the regulating component 12 adjusts the flow of the anesthetic gas and delivers it to the inside of the mixing component 13. The oxygen and the anesthetic gas are mixed by the mixing component 13 to adjust the anesthetic gas of different concentrations. When there is no anesthetic gas input, oxygen will continue to be delivered, the flow rate of oxygen will be increased, the blood oxygen saturation will be improved, and the normal function of important organs will be maintained. At the same time, the mixing component 13 can also heat the anesthetic gas and oxygen during the rotation process, reduce the evaporation of gas to the respiratory mucosa, keep the mucosa moist, and reduce the risk of mucosal damage and inflammation; First, the specific structure of the adjustment component 12 is disclosed. The adjustment component 12 includes a ball shell 120, which is fixedly connected to the top of the pillar 11. The outer wall of one side of the ball shell 120 is fixedly connected to the anesthesia trachea 2, and the outer wall of the other end of the ball shell 120 is fixedly connected to the mixing component 13. The ball shell 120 is movably connected to a ball box 121, and the outer wall of the ball box 121 is fixedly connected to a rotating rod 124. The end of the rotating rod 124 passing through the ball shell 120 is fixedly connected to a rotating disk 125, and the end of the rotating disk 125 is fixedly connected to a rotating member 126; The outer wall of the ball shell 120 is fixedly connected with a branch pipe 122, the outer wall of the branch pipe 122 is fixedly connected with a convex pipe 123, the turntable 125 is movably connected inside the branch pipe 122, the rotating member 126 is movably connected between the branch pipe 122 and the inside of the convex pipe 123, and the end of the convex pipe 123 is fixedly connected with an exhalation pipe 5; The rotating member 126 includes a push block 1260, which is movably connected to the inside of the convex tube 123. A slider 1261 is symmetrically fixedly connected to the outer wall of the push block 1260. The slider 1261 is movably connected to the inside of the slide groove on the inner wall of the convex tube 123. A thin elastic member 1262 is fixedly connected between the end of the slider 1261 and the end of the slide groove of the convex tube 123. The push block 1260 is movably connected to an axle rod 1263. The outer wall of the axle rod 1263 is fixedly connected to a support rod 1264. The support rod 1264 passes through the annular end of the push block 1260 and is movably connected to an internal convex rod 1265. The convex rod 1265 is fixedly connected to the end of the turntable 125.

[0024] See also Figure 4 and Figure 5 As shown, the patient's breathing gas is output through the expiratory tube 5, and the breathing gas pushes the rotating member 126 to move, so that the rotating member 126 drives the turntable 125 to rotate inside the branch pipe 122, and the turntable 125 drives the rotating rod 124 to rotate, so that the rotating rod 124 drives the ball box 121 to rotate inside the ball shell 120. When the opening of the ball box 121 rotates to the opening of the anesthesia trachea 2, it is convenient to input the anesthetic gas into the ball box 121. When the opening of the ball box 121 rotates to the end of the mixing box 130, the anesthetic gas is transported inside the mixing box 130. Each time the patient's breathing gas pushes the rotating member 126 to perform a reciprocating motion, the reciprocating motion of the rotating member 126 can drive the turntable 125 to rotate just one circle, so that the ball box 121 completes the delivery of the anesthetic gas once. The rotating member 126 pushes the push block 1260 toward the branch pipe 122 through gas, so that the slider 1261 moves on the inner wall of the convex pipe 123 to stretch the thin elastic member 1262. At the same time, the push block 1260 also drives the support rod 1264 to apply pressure to the convex rod 1265, so that the convex rod 1265 drives the turntable 125 to rotate inside the branch pipe 122 under the action of pressure. At the same time, during the rotation of the turntable 125, the convex rod 1265 and the support rod 1264 will be driven to move in the direction of its rotation, thereby driving the shaft 1263 to swing inside the push block 1260, so that the support rod 1264 will not affect the rotation of the turntable 125 when applying pressure. The rotation of the turntable 125 drives the rotating rod 124 and the ball box 121 to rotate, so as to transport the anesthetic gas. In order to ensure that the rotating member 126 can be blown by the breath and has a certain supporting hardness to complete the work of driving the rotation force, the push block 1260 is made of Kevlar fiber material, the slider 1261, the shaft 1263, the support rod 1264 and the protruding rod 1265 are all made of hollow aluminum alloy, and the thin elastic member 1262 is made of titanium alloy; The Kevlar fiber material itself has the characteristics of light weight and high strength, so that the push block 1260 has a certain flexibility and hardness. Figure 4 and Figure 5 Under the design shown in the figure, it is pushed by weak airflow and drives the subsequent rotation linkage work; through the characteristics of aluminum alloy itself with low density, light texture and good hardness, it is made according to Figure 4 and Figure 5 In the design shown, the slider 1261, the shaft 1263, the support rod 1264 and the protruding rod 1265 are all designed to be hollow structures, and the outer wall is an extremely thin aluminum alloy sheet structure. By controlling the thickness of the titanium alloy, it can be affected by the breath and realize linkage in an extremely thin state; the titanium alloy spring has the characteristics of high strength and low density, so that the thin elastic part 1262 is elastic and thin at the same time, making it easier to be blown by a weak airflow.

[0025] Secondly, the specific structure of the mixing component 13 is disclosed. The mixing component 13 includes a mixing box 130, which is fixedly connected to the outer wall of the spherical shell 120. A roller 131 is movably connected inside the mixing box 130. The end of the roller 131 passing through the mixing box 130 is fixedly connected to a motor 133. The outer wall of the roller 131 located inside the mixing box 130 is fixedly connected to a plurality of blades 132. The end of the mixing box 130 is fixedly connected to an intake pipe 4. The mixing box 130 is conical in shape near the intake pipe 4, a heating wire is provided inside the roller 131, and the blades 132 are made of metal.

[0026] See also Figure 3As shown, the output shaft of the motor 133 drives the roller 131 to rotate inside the mixing box 130, and the roller 131 drives the fan blade 132 to rotate, thereby promoting the gas flow speed inside the mixing box 130, accelerating the flow speed of the continuously input oxygen, and maintaining the continuous delivery of oxygen; at the same time, when anesthetic gas is delivered to the inside of the mixing box 130, the roller 131 rotates and drives the fan blade 132 to stir and mix the anesthetic gas and oxygen, so that the anesthetic gas and oxygen are evenly mixed, reducing the adverse reactions and complications that may occur when using anesthetic gas alone, and ensuring that the patient's body can obtain enough oxygen during the anesthesia process; By designing the mixing box 130 itself in a conical shape, the anesthetic gas input from the inside of the ball box 121 can be quickly dispersed inside the mixing box 130, and the anesthetic gas and oxygen can be accumulated inside the mixing box 130. In addition, since the mixing box 130 is designed to be gradually reduced in a conical shape toward the inhalation pipe 4, according to the continuity equation (flow rate = flow rate × flow area), when the gas passes through the conical or gradually reduced circular tubular contraction section, the flow area gradually decreases. In order to keep the flow rate unchanged, the flow rate of the gas must increase. Therefore, under the impetus of the fan blades 132, when oxygen and anesthetic gas flow from the mixing box 130 to the inhalation pipe 4, the gas flow rate will be increased, so that the patient can enter the anesthesia state faster and the operation preparation time can be shortened. At the same time, heat is generated by the electric heating wire inside the roller 131, wherein the working principle of the electric heating wire is based on the thermal effect of electric current as is known to those skilled in the art. When electric current passes through the electric heating wire, since the electric heating wire has a certain resistance, the current will encounter resistance when passing through the resistance, and the electrical energy will be converted into thermal energy. The heat energy is transported to the surface of the fan blade 132 through the rotation of the roller 131. Since the metal material of the fan blade 132 itself has thermal conductivity, a certain degree of heat transfer can be achieved in the process of contact between the gas and the fan blade 132, thereby preheating the gas, avoiding the cold stimulation caused by the direct entry of low-temperature gas into the respiratory tract, and reducing the patient's discomfort. At the same time, the warm gas has less stimulation to the respiratory mucosa, which can reduce mucosal vasoconstriction and spasm, and reduce the probability of mucosal damage and inflammation.

[0027] Finally, the specific structure of the one-way valve 61 is disclosed. The one-way valve 61 includes a valve tube 610. The two valve tubes 610 are respectively fixedly connected between the breathing mask 6 and the inhalation pipe 4 and the exhalation pipe 5. One of the valve tubes 610 is movably connected with a push plate 611 near the breathing mask 6, and the other valve tube 610 is movably connected with a push plate 611 near the inhalation pipe 4. The end of the push plate 611 is fixedly connected with a push rod 612, and the end of the push rod 612 is fixedly connected with a piston 613. The piston 613 is movably connected inside the conical groove of the inner wall of the valve tube 610, and a coarse elastic member 614 is fixedly connected between the push plate 611 and the end of the conical groove of the valve tube 610.

[0028] See also Fig. 9 and Fig.10 As shown, the anesthetic gas and oxygen are transported outward from the inhalation tube 4, thereby pushing the one-way valve 61 between the inhalation tube 4 and the breathing mask 6 to work, so that the anesthetic gas and oxygen enter the respiratory tract when the patient inhales, and at the same time, the gas when the patient breathes is blocked, and the one-way valve 61 between the exhalation tube 5 and the breathing mask 6 is pushed to work through the patient's exhalation; When there is a gas driving force, the push plate 611 will be pushed to move inside the valve tube 610, compressing the coarse elastic member 614 while driving the push rod 612 and the piston 613 to move, and moving the piston 613 out from the conical groove on the inner wall of the valve tube 610, thereby facilitating the gas to pass through the conical groove on the inner wall of the valve tube 610 through the push plate 611, thereby allowing the gas to circulate inside the valve tube 610. When there is no gas driving force to push the push plate 611, the rebound of the coarse elastic member 614 will drive the piston 613 to be blocked inside the conical groove of the valve tube 610, preventing the gas from flowing from the piston 613 to the push plate 611, thereby facilitating the one-way delivery of the gas from the inhalation tube 4 to the breathing mask 6 and from the breathing mask 6 to the exhalation tube 5.

[0029] In summary, the working principle of this solution is as follows: The gas exhaled by the patient pushes the push plate 611 inside the valve tube 610 between the exhalation tube 5 and the breathing mask 6 to move; during the movement, the push plate 611 compresses the thick elastic member 614, and at the same time drives the push rod 612 and the piston 613 to move, so that the piston 613 moves out of the tapered groove on the inner wall of the valve tube 610, thereby realizing the one-way transmission of gas from the breathing mask 6 to the exhalation tube 5; and when there is no gas driving force acting on the push plate 611, the thick elastic member 614 rebounds, driving the piston 613 to be blocked in the tapered groove of the valve tube 610 again, effectively preventing the gas from flowing back from the exhalation tube 5 to the breathing mask 6; The patient's breathing gas output through the expiratory tube 5 can push the push block 1260 to approach the branch tube 122; this makes the slider 1261 move on the inner wall of the convex tube 123 to stretch the thin elastic member 1262; at the same time, the push block 1260 also drives the support rod 1264 to apply pressure to the convex rod 1265, so that the convex rod 1265 drives the turntable 125 to rotate inside the branch tube 122 under the action of pressure; the rotation of the turntable 125 drives the rotating rod 124 to rotate, and then the rotating rod 124 drives the ball box 121 to rotate inside the ball shell 120; when the opening of the ball box 121 rotates to the opening of the anesthesia trachea 2, the anesthetic gas can be input into the ball box 121; when the opening of the ball box 121 rotates to the end of the mixing box 130, the anesthetic gas is transported to the inside of the mixing box 130; The output shaft of the motor 133 drives the roller 131 to rotate inside the mixing box 130, and stirs and mixes the anesthetic gas and oxygen entering the mixing box 130 to adjust the anesthetic concentration; the cone-shaped design of the mixing box 130 can increase the gas flow rate, so that the patient enters the anesthesia state faster and shortens the operation preparation time; at the same time, the electric heating wire inside the roller 131 heats up, and the roller 131 transfers the heat energy to the surface of the fan blade 132 when rotating; in the process of gas contacting the fan blade 132, the gas is preheated; in addition, the roller 131 drives the fan blade 132 to rotate, promotes the gas flow rate inside the mixing box 130, and transports the gas to the inside of the suction pipe 4; When the anesthetic gas and oxygen are transported outward from the inhalation tube 4, the push plate 611 inside the valve tube 610 between the inhalation tube 4 and the breathing mask 6 is pushed to move; the movement of the push plate 611 compresses the thick elastic member 614, and at the same time drives the push rod 612 and the piston 613 to move, so that the piston 613 moves out of the tapered groove on the inner wall of the valve tube 610, so as to facilitate the gas to be transported from the inhalation tube 4 to the breathing mask 6 for the patient to inhale; and when there is no gas driving force acting on the push plate 611, the thick elastic member 614 rebounds, driving the piston 613 to be blocked in the tapered groove of the valve tube 610 again, so as to prevent the breathing gas from flowing back from the breathing mask 6 to the inhalation tube 4; Example

[0030] See also Figure 6 and Figure 7 As shown, when the anesthesia device in the present application is used for patients with rapid breathing during surgery, a deeper anesthesia depth and a relatively high concentration of anesthetic gas are required to quickly achieve and maintain an appropriate anesthesia effect in the state of rapid breathing to cope with faster gas exchange and body metabolism; Therefore, through rapid breathing, the body's gas exchange speed is accelerated, which increases the flow rate of exhaled gas, and accelerates the breathing frequency and increases the breathing depth, so that the amount of gas exhaled per unit time increases. Therefore, the patient pushes the rotating part 126 to reciprocate more times, thereby increasing the number of times the ball box 121 delivers anesthetic gas, increasing the anesthetic gas flow rate, and improving the mixed concentration of anesthetic gas and oxygen, so that the patient can use a larger amount of anesthetic drugs to maintain an appropriate depth of anesthesia in a state of rapid breathing, so as to prevent shallow anesthesia due to rapid gas exchange. Example

[0031] See also Figure 6 and Figure 7As shown, when the anesthesia device in the present application is used for patients with weak breathing during surgery, since drug metabolism is relatively slow during weak breathing, the use of high-concentration anesthesia may lead to drug accumulation and increased side effects. Therefore, lower concentration anesthesia helps to reduce risks while ensuring the anesthesia effect. Therefore, in the weak breathing state, a shallower anesthesia depth and a lower concentration of anesthetic gas are usually suitable; Therefore, during weak breathing, the gas exchange efficiency is reduced, the flow of exhaled gas is relatively small, making the breathing shallow and slow, and the amount of gas discharged from the lungs during each breath is reduced, resulting in a significant decrease in the exhaled gas flow rate and exhalation frequency per unit time. Therefore, the number of times the patient pushes the rotating part 126 to reciprocate is reduced, thereby reducing the number of times the ball box 121 delivers anesthetic gas, reducing the anesthetic gas flow, and weakening the mixed concentration of anesthetic gas and oxygen, so that the patient can use a lower concentration of anesthesia when breathing weakly, which helps to reduce risks while ensuring the anesthetic effect.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention.
