Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an anesthetic gas mixing and anesthetic gas concentration detection device. Background Art

[0002] The anesthetic gas concentration detection device is used to monitor the concentration of each component in the anesthetic gas mixture in real time to ensure the accurate ratio of gases during anesthesia. The sensor detects the concentration of the gas and provides accurate data to adjust the output of the anesthetic gas to ensure the safety and stability of the depth of anesthesia. Common detection devices include infrared absorption analyzers, gas sensors, etc., which are widely used in operating rooms and anesthesia management systems.

[0003] A Chinese patent with patent announcement number CN211697689U discloses a device for mixing anesthetic gas and detecting the concentration of anesthetic gas, including a buffer mixing device and a detection device, wherein the buffer mixing device is connected to the detection device through an airway, the buffer mixing device is used to receive the anesthetic gas in the anesthesia machine and mix the anesthetic gas, and the detection device is used to detect the concentration of the anesthetic mixed gas coming out of the first anesthetic mixed gas outlet. Compared with the prior art, this patent increases the gas contact area by a spiral bend and further mixes the anesthetic gas evenly by the convection principle, thereby improving the accuracy of anesthetic drug concentration detection. This patent mixes the gas evenly by setting up a purely mechanical structure of two gas paths without providing additional energy, reducing energy consumption and being more practical.

[0004] However, the current concentration detection device has the following problems: the concentration detection device uses gas convection to mix the anesthetic gas, which will result in a slow anesthetic gas mixing speed. The effect of gas convection mixing depends to a large extent on the speed of the airflow. Under low flow or low airflow speed conditions, the gas mixing efficiency is poor, which means that it takes a long time for the anesthetic gas to mix evenly, thereby affecting the control and response speed of the anesthetic gas concentration. Therefore, we propose an anesthetic gas mixing and anesthetic gas concentration detection device. Summary of the invention

The two counterweights are respectively slidably installed on the rear side of the slide frame. The outside of the cylinder is equal to the size of the through hole of the through hole disk. The rotating rod here gradually speeds up during operation. During this process, the rotating rod drives the counterweight to rotate through the hinge rod. The counterweight will slide along the slide frame toward the rotating rod under the action of centrifugal force. The counterweight drives the plug cylinder to move toward the rear side of the rotating rod through the slide frame. The plug cylinder gradually separates from the through hole of the rearmost through hole disk, so that the plug cylinder no longer blocks the through hole of the rearmost through hole disk. At this time, the mixed gas can be discharged from the through hole of the rearmost through hole disk, so that the mixed gas of anesthetic gas and air inside the T-tube can be transmitted to the main body of the concentration detection equipment through the T-tube after being stirred and mixed for a period of time.

[0012] The present invention provides an anesthetic gas mixing and anesthetic gas concentration detection device, which has the following beneficial effects:

[0013] (1) The present invention arranges a gas mixing device so that the motor 1, the rotating rod, the bevel gear ring and the bevel gear cooperate to drive the two through-hole cylinders to rotate, so that the two through-hole cylinders rotate to spray the anesthetic gas and air into the T-tube. By rotating to spray the anesthetic gas and air, turbulence or air flow disturbance can be generated in the T-tube. This disturbance is conducive to the mixing of the gases, making the mixing of the anesthetic gas and the air more uniform, which is beneficial to the subsequent concentration detection device body to detect the concentration of the anesthetic gas and avoid measurement errors caused by uneven mixing of the anesthetic gas and the air. At the same time, the rotating rod drives the fan blades to further stir the mixed gas of the anesthetic gas and the air during the transmission process of the T-tube. Through the continuous stirring of the fan blades, the fluctuation of the gas concentration can be effectively avoided, so that the anesthetic gas can maintain a stable concentration during the transportation process.

[0014] (2) The present invention provides a slow flow device so that the perforated disk and the fixed disk extend the path of the mixed gas of anesthetic gas and air in the T-tube. The extension of the mixed gas flow path means that the contact time of the anesthetic gas and air becomes longer, thereby making the mixing process of the anesthetic gas and air more complete. In addition, since the mixed gas flow path is longer, the gas flow may undergo more disturbances and adjustments, thereby avoiding the situation of too fast or too rapid air flow, which helps to reduce the fluctuation of gas flow rate and ensure that the gas flows more smoothly in the pipeline. At the same time, the rotating rod, the hinge rod, the counterweight block, and the slide frame cooperate to drive the plug cylinder to gradually separate from the through hole of the rearmost through hole disk, so that the plug cylinder no longer blocks the through hole of the rearmost through hole disk. At this time, the mixed gas can be discharged from the through hole of the rearmost through hole disk, so that the mixed gas of anesthetic gas and air in the T-tube can be transmitted to the main body of the concentration detection device through the T-tube after being stirred and mixed for a period of time, thereby ensuring that the mixed gas has enough time to be stirred and mixed before passing through the T-tube, and avoiding the problem of uneven concentration or premature delivery of anesthetic gas.

[0015] (3) The present invention sets an adjustment device so that the motor 2, the screw, the threaded block, the U-shaped rod, and the T-shaped tube cooperate to drive the adjustment disk to move. The exhaust volume of the through-hole cylinder 35 can be adjusted by moving the adjustment disk, and the mixing ratio of the anesthetic gas and the air can be accurately adjusted between the L-shaped trachea 1 and the L-shaped trachea 2, which is beneficial for the staff to control the concentration of the anesthetic gas; at the same time, the through-hole cylinder, the L-shaped connecting rod, and the adjustment disk cooperate to drive the inclined blades to disturb the anesthetic gas or air ejected from the through-hole cylinder, thereby ensuring that the anesthetic gas or air can be accurately guided and evenly distributed.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1 - Figure 8 An embodiment of the present invention is: an anesthetic gas mixing and anesthetic gas concentration detection device, comprising a device body 1, one side of the device body 1 is connected to a concentration detection device body 2 through a pipeline, the interior of the concentration detection device body 2 is provided with a detection module for detecting the concentration of anesthetic gas, the interior of the device body 1 is provided with a gas mixing device 3, the gas mixing device 3 comprises an L-shaped air pipe 1 31, an L-shaped air pipe 2 32, a T-shaped pipe 33, a rotating rod 34, two through-hole cylinders 35, a bevel gear ring 36, two bevel gears 37, and a motor 1 38, the L-shaped air pipe 1 31 and the L-shaped air pipe 2 32 are respectively fixed on both sides of the front side of the device body 1, one end of the T-shaped pipe 33 is fixed between the L-shaped air pipe 1 31 and the L-shaped air pipe 2 32, the other end of the T-shaped pipe 33 penetrates and is fixed on the rear side of the inner wall of the device body 1, and the other end of the T-shaped pipe 33 is connected to the concentration detection device body 2, the two The through-hole cylinders 35 are rotatably mounted on the ends of the L-shaped trachea 1 31 and the L-shaped trachea 2 32 that are close to each other. The two bevel gears 37 are respectively fixed on the sides of the two through-hole cylinders 35 that are close to each other. The rotating rod 34 is rotatably mounted on the inner wall of the device body 1, and the rotating rod 34 is driven by the motor 1 38. The bevel gear ring 36 is fixed on the outside of the rotating rod 34, and the bevel gear ring 36 is meshed with the bevel gear 37. Through the arrangement of the above structure, the two through-hole cylinders 35 can rotate and spray the anesthetic gas and air into the T-tube 33. By rotating and spraying the anesthetic gas and air, turbulence or airflow disturbance can be generated in the T-tube 33. This disturbance is conducive to the mixing of the gases, making the mixing of the anesthetic gas and the air more uniform, which is beneficial to the subsequent concentration detection device body 2 to detect the concentration of the anesthetic gas and avoid measurement errors caused by uneven mixing of the anesthetic gas and the air.

[0027] The gas mixing device 3 also includes a plurality of fan blades 39, which are evenly and equidistantly fixed on the outer wall of the rotating rod 34, and the fan blades 39 are located on the side of the rotating rod 34 away from the bevel gear ring 36. Through the arrangement of the above structure, the fan blades 39 will further stir the mixed gas of the anesthetic gas and air during the transmission process of the T-tube 33. Through the continuous stirring of the fan blades 39, the fluctuation of the gas concentration can be effectively avoided, so that the anesthetic gas can maintain a stable concentration during the transportation process.

[0028] A slow flow device 4 is provided inside the T-shaped tube 33. The slow flow device 4 includes two straight frames 41, a plurality of through hole disks 42, and a plurality of ring frames 44. The two straight frames 41 are respectively fixed on both sides of the inner wall of the T-shaped tube 33. A plurality of through hole disks 42 are evenly and equidistantly fixed between the two straight frames 41. A plurality of ring frames 44 are evenly and equidistantly fixed between the two straight frames 41. The ring frames 44 are located between two adjacent through hole disks 42. A fixed disk 43 is fixed on a plurality of ring frames 44 located on the same plane. The inner diameter of the through hole of the through hole disk 42 is greater than five centimeters of the rotating rod 34. The outer wall of the fixed disk 43 is less than five centimeters of the inner diameter of the T-shaped tube 33. The inner diameter of the fixed disk 43 and the outer portion of the rotating rod 34 are clearance-matched. Through the arrangement of the above-mentioned structure, the through-hole disk 42 and the fixed disk 43 extend the path of the mixed gas of the anesthetic gas and the air in the T-tube 33. The extension of the mixed gas flow path means that the contact time of the anesthetic gas and the air is prolonged, thereby making the mixing process of the anesthetic gas and the air more complete. In addition, since the mixed gas flow path is longer, the gas flow process may undergo more disturbances and adjustments, thereby avoiding the situation of too fast or too rapid airflow, which helps to reduce the fluctuation of the gas flow rate and ensure that the gas flows more smoothly in the pipeline.

[0029] The slow flow device 4 also includes a plug cylinder 45, a slide frame 48, two hinged rods 46, and two counterweights 47. The slide frame 48 is slidably mounted on the outside of the rotating rod 34, and the slide frame 48 is located at the rear side of the through-hole disk 42 at the rearmost side. The plug cylinder 45 is fixed to the front side of the slide frame 48, and the plug cylinder 45 is located between the through-hole disk 42 and the fixed disk 43. The two counterweights 47 are slidably mounted on the rear side of the slide frame 48, one end of the two hinged rods 46 is respectively hinged to the outside of the two counterweights 47, and the other ends of the two hinged rods 46 are respectively hinged to the rear outer wall of the rotating rod 34, and a torsion spring is provided between the hinged rod 46 and the outside of the rotating rod 34. The inner diameter of the plug cylinder 45 is equal to the outer diameter of the rotating rod 34. There is a clearance fit between them, and the outside of the plug tube 45 is equal to the through hole of the through hole disk 42. Through the arrangement of the above structure, the plug tube 45 is gradually separated from the through hole of the rearmost through hole disk 42, so that the plug tube 45 no longer blocks the through hole of the rearmost through hole disk 42. At this time, the mixed gas can be discharged from the through hole of the rearmost through hole disk 42, so that the mixed gas of anesthetic gas and air inside the T-tube 33 can be transmitted to the concentration detection device body 2 through the T-tube 33 after being stirred and mixed for a period of time, thereby ensuring that the mixed gas has enough time to be stirred and mixed before passing through the T-tube 33, and avoiding the problem of uneven concentration or premature delivery of anesthetic gas.

[0030] When in use, the outlet of the anesthetic vaporizer is connected to the L-shaped air pipe 1 31, and the external air pipe is connected to the L-shaped air pipe 2 32. The anesthetic gas will be transmitted to the through-hole cylinder 35 corresponding to the L-shaped air pipe 1 31 through the L-shaped air pipe 1 31, and the external air pipe will be transmitted to the through-hole cylinder 35 corresponding to the L-shaped air pipe 2 32 through the L-shaped air pipe 2 32. Here, the anesthetic gas and air are both transported by the air pump, and the two through-hole cylinders 35 respectively spray the anesthetic gas and air into the T-shaped tube 33, and at the same time, the motor 1 38 is started, the motor 1 38 drives the rotating rod 34 to rotate, the rotating rod 34 drives the bevel gear ring 36 to rotate, and the bevel gear ring 36 drives the two bevel gears 37 to rotate, so that the two bevel gears 37 respectively drive the two through-hole cylinders 35 to rotate, so that the two through-hole cylinders 35 rotate to spray the anesthetic gas and air into the T-shaped tube 33, and the anesthetic gas and air are sprayed in a rotating manner. Air can generate turbulence or air flow disturbance in the T-tube 33. This disturbance is conducive to the mixing of gases, making the mixing of anesthetic gas and air more uniform, which is beneficial to the subsequent concentration detection equipment body 2 to detect the concentration of anesthetic gas and avoid measurement errors caused by uneven mixing of anesthetic gas and air; at the same time, the rotating rod 34 drives the fan blades 39 to rotate, and the fan blades 39 will further stir the mixed gas of anesthetic gas and air during the transmission process of the T-tube 33. Through the continuous stirring of the fan blades 39, the fluctuation of gas concentration can be effectively avoided, so that the anesthetic gas maintains a stable concentration during the transportation process. After the anesthetic gas and air are sprayed into the inside of the T-tube 33, the T-tube 33 will transmit the mixed anesthetic gas and air to the concentration detection equipment body 2, and the detection module of the concentration detection equipment body 2 will detect the concentration of the anesthetic gas.

[0031] When the mixed gas of anesthetic gas and air is transmitted inside the T-tube 33, the mixed gas will pass through the through holes of the through hole plate 42 and the outer diameter of the fixed plate 43 in sequence. The through hole plate 42 and the fixed plate 43 extend the path of the mixed gas of anesthetic gas and air in the T-tube 33. The extension of the mixed gas flow path means that the contact time of the anesthetic gas and the air is prolonged, thereby making the mixing process of the anesthetic gas and the air more complete. In addition, since the mixed gas flow path is longer, the gas flow process may undergo more disturbances and adjustments, avoiding the situation of too fast or too rapid airflow, which helps to reduce the fluctuation of gas flow rate and ensure that the gas flows more smoothly in the pipeline. The rotating rod 34 here gradually speeds up during operation. In this process, the rotating rod 34 is connected to the hinge rod 4 6 drives the counterweight 47 to rotate. The counterweight 47 slides along the slide frame 48 toward the direction of the rotating rod 34 under the action of centrifugal force. The counterweight 47 drives the plug cylinder 45 to move toward the rear side of the rotating rod 34 through the slide frame 48. The plug cylinder 45 is gradually separated from the through hole of the rearmost through hole disk 42, so that the plug cylinder 45 no longer blocks the through hole of the rearmost through hole disk 42. At this time, the mixed gas can be discharged from the through hole of the rearmost through hole disk 42, so that the mixed gas of the anesthetic gas and the air inside the T-tube 33 can be transmitted to the concentration detection device body 2 through the T-tube 33 after being stirred and mixed for a period of time, thereby ensuring that the mixed gas has enough time to be stirred and mixed before passing through the T-tube 33, and avoiding the problem of uneven concentration or premature delivery of the anesthetic gas.

[0032] See also Figure 1 - Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, an adjustment device 5 is provided above the two through-hole cylinders 35 .

[0033] The regulating device 5 comprises a second motor 51, a threaded block 52, a screw 53, a U-shaped rod 54, a fixing ring 55 and an adjusting disk 56. The second motor 51 is fixed on the top of the T-shaped tube 33, the screw 53 is fixed on the output end of the second motor 51, the threaded block 52 is threadedly connected to the outside of the screw 53, one end of the U-shaped rod 54 is fixed to the outside of the threaded block 52, the other end of the U-shaped rod 54 passes through the side wall of the T-shaped tube 33, the fixing ring 55 is fixed to the other end of the U-shaped rod 54, the adjusting disk 56 is rotatably mounted on the side of the fixing ring 55 away from the U-shaped rod 54, the adjusting disk 56 is sleeved on the outer wall of the through-hole tube 35, and the inner diameter of the adjusting disk 56 is clearance-matched with the outside of the through-hole tube 35. Through the arrangement of the above structure, the movement of the adjusting disk 56 can adjust the through-hole exhaust volume of the through-hole tube 35, so that the mixing ratio of the anesthetic gas and the air can be accurately adjusted between the L-shaped trachea 1 31 and the L-shaped trachea 2 32, which is beneficial for the staff to control the concentration of the anesthetic gas.

[0034] The adjusting device 5 also includes a plurality of L-shaped connecting rods 57 and a plurality of inclined blades 58. The plurality of L-shaped connecting rods 57 are evenly fixed on the outer wall of the through-hole tube 35 on one side close to the center of the T-shaped tube 33, and the L-shaped connecting rods 57 penetrate the adjusting disk 56. The plurality of inclined blades 58 are evenly fixed on the one side of the adjusting disk 56 close to the center of the T-shaped tube 33. Through the arrangement of the above structure, the inclined blades 58 disturb the anesthetic gas or air ejected from the through-hole tube 35, thereby ensuring that the anesthetic gas or air can be accurately guided and evenly distributed.

[0035] When in use, the motor 2 51 is started at the same time, and the motor 2 51 drives the screw 53 to rotate forward or reversely. The screw 53 drives the U-shaped rod 54 to move toward the center of the T-shaped tube 33 or away from the T-shaped tube 33 through the threaded block 52. The U-shaped rod 54 drives the adjusting disk 56 to move along the outside of the through-hole tube 35 toward the center of the T-shaped tube 33 or away from the T-shaped tube 33 through the fixing ring 55. When the adjusting disk 56 moves toward the center of the T-shaped tube 33, the adjusting disk 56 can control the amount of anesthetic gas and air discharged from the L-shaped trachea 1 31 and the L-shaped trachea 2 32 to decrease. When the adjusting disk 56 moves toward the direction away from the center of the T-shaped tube 33, the adjusting disk 56 can control the amount of anesthetic gas and air discharged from the L-shaped trachea 1 31 and the L-shaped trachea 2 32 to increase. The movement of the adjusting disk 56 can adjust the exhaust volume of the through hole of the through hole cylinder 35, and can accurately adjust the mixing ratio of the anesthetic gas and the air between the L-shaped trachea 1 31 and the L-shaped trachea 2 32, so as to facilitate the staff to control the concentration of the anesthetic gas; when the through hole cylinder 35 rotates, the through hole cylinder 35 drives the L-shaped connecting rod 57 to rotate, the L-shaped connecting rod 57 drives the adjusting disk 56 to rotate, and the adjusting disk 56 drives the inclined blade 58 to rotate, so that the inclined blade 58 disturbs the anesthetic gas or air ejected from the through hole cylinder 35, thereby ensuring that the anesthetic gas or air can be accurately guided and evenly distributed. It is worth noting that since the fixing ring 55 and the adjusting disk 56 are rotatably connected, the fixing ring 55 will not interfere with the movement of the adjusting disk 56.
