Description

Technical Field

[0001] The invention relates to the technical field of clinical anesthesia, in particular to a clinical anesthetic gas concentration control device. Background Art

[0002] Anesthesia machines are mainly used for inhalation anesthesia in clinical practice. The principle is to use oxygen to volatilize anesthetics through an anesthetic evaporator to produce a mixed gas of oxygen and anesthetics, and then input the mixed gas with anesthetics into the patient to put the patient in an anesthetized state. The key component that affects the concentration of anesthetic drugs is the evaporator. According to the adjustment method of the evaporation flow, it can be divided into bypass variable type and measured flow type. When the evaporation switch of the bypass variable evaporator is turned on, the gas flowing into the evaporator is divided into two paths, one path flows into the evaporation chamber to take away the anesthetic vapor, and the other path passes through the bypass, and then the two airflows merge downstream. After merging, they are directly Detection, studies have shown that the gas in the evaporator of the anesthesia machine is very easy to mix unevenly, which seriously affects the detection accuracy of the anesthetic drug concentration and also affects the administration of anesthetic drugs. Due to volatility, the temperature of anesthetic drugs continues to decrease during the continuous volatilization process, resulting in a continuous decrease in their volatility, making the concentration of anesthetic drugs difficult to control. The current solution is temperature compensation. The principle of temperature compensation is to use a temperature-sensitive brass tube or bimetallic strip in contact with the anesthetic solution, which will produce corresponding deformation when the temperature is low. On the basis of the original variable bypass, the amount of positive gas is increased to maintain a constant concentration of volatile anesthetic drugs.

[0003] The existing clinical anesthetic gas concentration control device has structural design defects, resulting in the temperature of the anesthetic drug continuously decreasing during the volatilization process, causing its volatilization ability to continuously decrease, and the gas in the anesthesia machine is very easy to mix unevenly, which seriously affects the detection accuracy of the anesthetic drug concentration.

[0013] Preferably, the guide assembly includes a shell, the surface of the shell is fixedly connected to the middle position of the surface of the mechanism wall, the inner side surface of the shell is rotatably connected to a worm, the shell supports the worm and the worm wheel, and the worm wheel rotates on the inner side surface of the shell, thereby driving the rotating plate to rotate.

[0014] Preferably, a worm gear is rotatably connected to the inner side surface of the shell, a rotating plate is fixedly connected to the inner side surface of the worm gear, and a fan is fixedly connected to the surface of the rotating plate.

[0015] Preferably, the damping assembly includes a rod body, the top end of the rod body is fixedly connected to the top of the inner side surface of the mechanism wall, the bottom end of the rod body is fixedly connected to an arcuate wall, the bottom of the arcuate wall is fixedly connected to a spherical wall, and the anesthetic liquid enters the flared position through the opening of the perforated wall. The flared opening and the plastic net slow down the flow rate of the liquid to prevent the supplementary anesthetic liquid from impacting the anesthetic liquid in the embedded tank.

[0016] Preferably, a gap is provided between the arc-shaped wall surface and the inner side surface of the mechanism wall, and a baffle is fixedly connected to a position of the spherical wall surface near the edge.

[0017] The present invention provides a clinical anesthetic gas concentration control device, which has the following beneficial effects: 1. In the clinical anesthetic gas concentration control device, the insulating oil is heated inside the heating component. After the device has been used for a period of time, the inside of the catheter is filled with supplementary anesthetic liquid, and the insulating oil transfers the temperature to the supplementary anesthetic liquid through the copper sheet. The supplementary anesthetic liquid is guided to the embedded tank. The temperature of the insulating oil is kept constant, and the amount of the anesthetic liquid is kept constant, which can effectively prevent the temperature of the anesthetic drug itself from continuously decreasing, and solves the problem that the temperature of the anesthetic drug itself is continuously decreasing during the continuous volatilization process, resulting in a continuous decrease in its volatilization ability.

[0018] 2. The clinical anesthetic gas concentration control device has insulating oil located between the tank body and the embedded tank. Anesthetic liquid is stored in the embedded tank. The plastic net hinders the flow of supplementary anesthetic liquid. The embedded tank conducts heat to the anesthetic liquid to evaporate it into a gas state. The stirring device stirs the anesthetic liquid near the embedded tank. The anesthetic liquid contacts the embedded tank over a large area. The continuous temperature conduction characteristics of the insulating oil allow the anesthetic liquid to be evenly heated, which can make the anesthetic liquid evaporate into a gas state more stably.

[0019] 3. In the clinical anesthetic gas concentration control device, oxygen flows into the tank body, and the oxygen carries the anesthetic gas into the wall of the mechanism. The guiding component increases the gas flow rate, and the rubber plug fixes the spiral sheet. The spiral sheet makes the flow direction of the mixed gas a highly directional spiral direction. The mixed gas is accelerated to collide with the surface of the damping component. After the gas impact, the distribution of the internal components is chaotic, which solves the problem that the gas in the anesthesia machine is easily unevenly mixed, which seriously affects the detection accuracy of the anesthetic drug concentration.

[0020] 4. The clinical anesthetic gas concentration control device has a rotating plate set at the position of the fan blade. The rotation of the fan causes the airflow below the spiral plate to quickly enter the spiral plate. The mixed gas of oxygen and anesthetic gas forms a directional spiral airflow on the spiral plate. The spiral mixed airflow hits the bottom of the spherical wall. The impact force makes the gas components fully mixed. The fan is driven to rotate by the meshing of the worm gear and the worm, which prevents the mixed airflow with a higher temperature from directly hitting the surface of the motor, causing the motor to be easily damaged.

[0021] 5. In the clinical anesthetic gas concentration control device, the spiral mixed gas hits the bottom of the spherical wall, and the kinetic energy of the airflow is converted into impact force to change the flow direction of the gas. The airflow near the gap between the curved wall surface and the mechanism wall hits the surface of the baffle plate, and the airflow is turned back to prevent the gas from flowing out directly through the gap without being hit. The air outlet pipe is connected to an air pump to guide the fully mixed gas components through the curved wall into the air outlet pipe, thereby making the composition of the anesthetic mixed gas more stable.

As the anesthetic liquid evaporates, its amount gradually decreases. The compensation mechanism 3 heats the anesthetic liquid and adds it to the anesthetic liquid in the tank body 2. The compensation mechanism 3 includes an embedded tank 31 and a heating component 32. The heating component 32 heats the insulating oil and then passes it into the tank body 2. A liquid guide tube 33 is fixedly connected to the middle position of the inner side of the heating component 32. The heating component 32 heats the anesthetic liquid flowing in the liquid guide tube 33, and the heated liquid is passed into the embedded tank 31 to compensate for the amount of the anesthetic liquid.

The air inlet pipe 5 introduces oxygen into the tank body 2. The anesthetic liquid is heated and evaporated into anesthetic gas.

After the device has been used for a period of time, supplementary anesthetic liquid is introduced into the interior of the catheter 33, and the insulating oil transfers the temperature to the supplementary anesthetic liquid through the copper sheet 34. The supplementary anesthetic liquid is guided into the embedded tank 31. The temperature of the insulating oil remains constant, and the amount of the anesthetic liquid remains constant, which can effectively prevent the temperature of the anesthetic drug itself from continuously decreasing, and solves the problem that the temperature of the anesthetic drug itself continues to decrease during the continuous volatilization process, resulting in a continuous decrease in its volatilization ability.

[0027] like Figure 3 , Figure 4 , Figure 5 As shown, the heating component 32 includes an oil storage wall 321, the bottom of the oil storage wall 321 is fixedly connected to the top of the base 1, an oil pipe 322 is fixedly connected to the lower position of the surface of the oil storage wall 321, a heating strip 323 is fixedly connected to the inner side of the oil storage wall 321, a side of the surface of the oil storage wall 321 away from the oil pipe 322 is fixedly connected to the lower position of the surface of the tank body 2, an oil pump 324 is fixedly connected to the bottom of the oil storage wall 321 near the tank body 2, and the impact-proof component 35 includes a flaring wall 351, one side of the flaring wall 351 is fixedly connected to an end of the liquid guide tube 33 near the embedded tank 31, a position of the surface of the flaring wall 351 near the flaring is fixedly connected to the surface of the embedded tank 31, an opening wall 352 is fixedly connected to the middle position of the inner side of the flaring wall 351, a sealing cover 353 is fixedly connected to the middle position of the surface of the opening wall 352, and a plastic net 354 is fixedly connected to the position between the opening wall 352 and the flaring wall 351.

[0028] When in use, the oil pipe 322 passes insulating oil into the interior of the oil storage wall 321, and the insulating oil is heated in the oil storage wall 321. The oil pump 324 adds the high-temperature insulating oil in the oil storage wall 321 into the tank body 2. The insulating oil is located between the tank body 2 and the embedded tank 31. Anesthetic liquid is stored in the embedded tank 31. The plastic net 354 hinders the flow of the supplementary anesthetic liquid. The embedded tank 31 conducts heat to the anesthetic liquid to evaporate it into a gas state. The stirring device 36 stirs the anesthetic liquid near the embedded tank 31. The anesthetic liquid contacts the embedded tank 31 over a large area, and the continuous temperature conduction characteristics of the insulating oil make the anesthetic liquid evenly heated, which can make the anesthetic liquid evaporate into a gas state more stably.

[0029] like Figure 3 , Figure 6As shown, the heating component 32 heats the insulating oil and then passes it into the tank body 2. The middle position of the inner side surface of the heating component 32 is fixedly connected with a liquid guide tube 33. The heating component 32 heats the anesthetic liquid flowing in the liquid guide tube 33, and the heated liquid is passed into the embedded tank 31 to compensate for the amount of the anesthetic liquid. The anti-uneven mechanism 6 includes a mechanism wall 61. The lower position of the surface of the mechanism wall 61 is fixedly connected to the middle position of the inner side surface of the cover body 4. The bottom of the inner side surface of the mechanism wall 61 is connected to a rubber plug 62 through friction resistance. The inner side surface of the rubber plug 62 is fixedly connected to a spiral sheet 63. The middle position of the surface of the mechanism wall 61 is fixedly connected to a guide component 64. The top of the inner side surface of the mechanism wall 61 is fixedly connected to a damping component 65. The upper position of the surface of the mechanism wall 61 is fixedly connected to an air outlet pipe 66.

[0030] When in use, the bottom of the mechanism wall 61 extends close to the position of the embedded tank 31, and the anesthetic liquid inside the embedded tank 31 evaporates into a gas state. The mechanism wall 61 is connected to an external air pump to discharge the gas, and oxygen flows into the tank body 2. The oxygen carries the anesthetic gas into the mechanism wall 61, and the guide component 64 increases the gas flow rate. The rubber plug 62 fixes the spiral sheet 63, and the spiral sheet 63 makes the flow direction of the mixed gas a highly directional spiral direction. The mixed gas is accelerated to collide with the surface of the damping component 65. After the gas impact, the distribution of the internal components is chaotic, which solves the problem that the gas in the anesthesia machine is easily mixed unevenly, which seriously affects the detection accuracy of the anesthetic drug concentration.

[0031] like Figure 6 , Figure 7 , Figure 8 As shown, the guide assembly 64 includes a shell 641, the surface of the shell 641 is fixedly connected to the middle position of the surface of the mechanism wall 61, the inner side surface of the shell 641 is rotatably connected to a worm 642, the inner side surface of the shell 641 is rotatably connected to a worm gear, the inner side surface of the worm gear is fixedly connected to a rotating plate 643, the surface of the rotating plate 643 is fixedly connected to a fan 644, and the damping assembly 65 includes a rod body 651, the top of the rod body 651 is fixedly connected to the top of the inner side surface of the mechanism wall 61, the bottom end of the rod body 651 is fixedly connected to an arc wall 652, the bottom of the arc wall 652 is fixedly connected to a spherical wall 653, a gap is set between the surface of the arc wall 652 and the inner side surface of the mechanism wall 61, and a baffle 654 is fixedly connected to the surface of the spherical wall 653 near the edge.

[0032] When in use, the shell 641 supports the worm 642 and the worm wheel. The worm wheel rotates on the inner side of the shell 641, thereby driving the rotating piece 643 to rotate. The rotating piece 643 is set at the position of the blade of the fan 644. The rotation of the fan 644 allows the airflow below the spiral piece 63 to quickly enter the spiral piece 63. The mixed gas of oxygen and anesthetic gas forms a directional spiral airflow on the spiral piece 63. The spiral mixed airflow hits the bottom of the spherical wall 653. The impact force makes the gas components fully mixed. The worm wheel and the worm 642 are engaged to drive the fan 644 to rotate, so as to avoid the problem of high-temperature mixed airflow directly hitting the surface of the motor, causing the motor to be easily damaged.

[0034] When in use, the anesthetic liquid enters the expanded position through the opening of the perforated wall 352. The expanded position and the plastic net 354 slow down the flow rate of the liquid to prevent the supplementary anesthetic liquid from impacting the anesthetic liquid in the embedded tank 31. The spiral mixed gas hits the bottom of the spherical wall 653, and the kinetic energy of the airflow is converted into impact force to change the flow direction of the gas. The airflow near the gap between the surface of the curved wall 652 and the mechanism wall 61 hits the surface of the deflector 654, and the airflow is turned back to prevent the gas from flowing out directly through the gap without impact. The outlet pipe 66 is connected to an external air pump to guide the fully mixed gas components through the curved wall 652 to the outlet pipe 66, thereby making the composition of the anesthetic mixed gas more stable.
