Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia devices, in particular to an inhalation anesthesia device for cardiology. Background Art

[0002] Anesthesia is an essential clinical procedure for various surgeries and examinations. It is an important means to ensure patient safety and a smooth and easy-to-operate surgical examination process. General anesthesia is divided into three methods of administration: intravenous, inhalation, and combined intravenous and inhalation.

[0003] When the cardiology department is performing complex congenital heart disease surgeries, the patient may be in a coma, which makes it impossible for medical staff to anesthetize the patient according to the conventional anesthesia dosage. This is because excessive or insufficient anesthesia may easily occur, thus threatening the patient's personal safety.

[0004] In addition, anesthetics are harmful to the human body, and people have always had concerns about the use of anesthetics; therefore, people hope to ensure that the anesthetics are just enough during the use of anesthetics and try not to use them excessively. However, if the anesthetics are insufficient, there will still be great risks. In order to ensure the effectiveness of the operation and avoid trauma to the patient, the amount of anesthetics often needs to be used in sufficient amounts. Although the use of anesthetics has undergone a large number of clinical trials, it is impossible to use anesthesia based on data in daily operations, which leads to the anesthesiologist having to adjust the anesthetic dosage according to the patient's condition at all times during the operation.

[0005] To this end, we proposed an inhalation anesthesia device for cardiology. Summary of the invention

[0006] The purpose of the present invention is to provide an inhalation anesthesia device for cardiology to solve the problems raised in the above background technology.

[0032] 1. In the present invention, during use, the anesthetic gas flow meter and the oxygen gas flow meter can be used to perform data statistics on the gas flow in real time, so that the ratio of the mixed anesthetic gas can be accurately controlled. After the mixed anesthetic gas passes through the anesthetic gas concentration detector, it can be obtained whether the mixed gas meets the requirements, thereby ensuring the effect of the anesthetic gas on the patient. After the mixed gas is absorbed by the patient, the exhaled gas is detected by the respiratory gas concentration detector, and the anesthetic gas concentration and carbon dioxide concentration in the patient's exhaled gas at this time can be obtained. After the data is obtained, the servo motor can be started, and the servo motor drives the gear plate to rotate with the gear, and then the corresponding top opening of the air outlet pipe can be adjusted under the action of the diamond sealing plate, thereby reducing the outflow of anesthetic gas or oxygen gas, and then the ratio can be readjusted, thereby meeting the patient's requirements for anesthetic gas during surgery, thereby ensuring the patient's safety and avoiding excessive or insufficient anesthetic gas.

[0047] 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.

[0048] See also Figures 1 to 9 , the present invention provides a technical solution:

[0049] An inhalation anesthesia device for cardiology includes a main container box 1, the interior of the main container box 1 is a cavity structure, and a sealing plate is rotatably installed on the front end surface. The sealing plate is rotatably connected to the main container box 1 by a hinge. The sealing plate is used to protect the device inside the main container box 1, such as Figure 1 and Figure 5 shown.

[0050] Casters 2 are rotatably installed at the four corners of the lower end surface of the main container box 1. The main container box 1 can be moved to the position where the operation is required under the action of the casters 2. Moreover, the casters 2 are locked to prevent the casters 2 from moving independently.

[0051] Then, a sub-box 3 is fixedly installed on the front of the upper end of the main container box 1. An operation button 4 is provided on the upper end of the sub-box 3 for starting the device and viewing and saving subsequent data. A display screen 5 is fixedly installed on the upper end of the main container box 1 located at the rear end of the sub-box 3. The display screen 5 can display the usage of anesthetic gas and oxygen gas in real time, as well as the gas concentration subsequently exhaled by the patient, so that medical staff can intuitively see the desired data.

[0052] An anesthetic gas tank 6 is fixedly installed on the left side of the inner bottom surface of the main container box 1, and an oxygen gas tank 7 is fixedly installed on the right side. Among them, an air outlet pipe 8 is fixedly installed on the upper end of the anesthetic gas tank 6 and the oxygen gas tank 7. The air outlet pipe 8 is in a through state with the fixedly connected anesthetic gas tank 6 and the oxygen gas tank 7. Then, pressure gauges 9 are fixedly installed on the outer circumferential surface of the upper ends of the two air outlet pipes 8 to perform real-time detection of the pressure inside the anesthetic gas tank 6 and the oxygen gas tank 7 to ensure that the internal pressure is sufficient. Figure 5 shown.

[0053] Secondly, an outer cover shell 10 is fixedly installed on the outer circumferential surface of the anesthetic gas tank 6 and the oxygen gas tank 7 near the top. The interior of the outer cover shell 10 is a cavity structure, and the top is open. Then, four servo motors 11 are evenly fixedly installed in a circular array on the inner bottom surface of the outer cover shell 10 and located outside the air outlet pipe 8. Gears 12 are fixedly installed on the output shafts of the servo motors 11. Figure 7 shown.

[0054] A chassis 13 is fixedly installed on the top of the two air outlet pipes 8, and a first slide groove 14 is opened at the upper end surface of the chassis 13 near the edge. Four first columns 15 are evenly fixedly installed in a circular array near the inner side of the upper end surface of the chassis 13, and then a diamond-shaped sealing plate 16 is rotatably installed on the outer side of each first column 15, wherein a second slide groove 17 in an inclined state is opened from the upper end surface to the lower end surface of each diamond-shaped sealing plate 16, and the upper end of the first column 15 is slidably installed in the inside of the second slide groove 17, so that the diamond-shaped sealing plate 16 can be rotated. Figure 8 shown.

[0055] A gear plate 18 is rotatably mounted on the upper end surface of the diamond-shaped sealing plate 16, and six second columns 19 are evenly fixedly mounted in a circular array on the lower end surface of the gear plate 18. The lower end of the second column 19 is fixedly connected to one end of the outer side of the adjacent diamond-shaped sealing plate 16, but the second column 19 is away from one end of the gear plate 18 and extends through the diamond-shaped sealing plate 16 to the inside of the first slide groove 14, and the gear on the circumferential surface of the gear plate 18 is meshed with the gear 12.

[0056] Therefore, during use, the servo motor 11 is started, and the output shaft of the servo motor 11 rotates with the gear 12, and the gear 12 can drive the gear plate 18 to rotate. When the gear plate 18 rotates, it will move synchronously with the second column 19, and the second column 19 will rotate around the first column 15 with the diamond-shaped sealing plate 16, but due to the cooperation between the second slide groove 17 and the first column 15, the center of the diamond-shaped sealing plate 16 can be in an open or closed state; wherein, the upper end surface to the lower end surface of the chassis 13 and the gear plate 18 are provided with vents 20, therefore, when the center of the six diamond-shaped sealing plates 16 is in an open state, the gas inside the anesthetic gas tank 6 and the oxygen gas tank 7 can enter through the outlet pipe 8 into the subsequent anesthetic gas flow meter 21 and the oxygen gas flow meter 22, therefore, the lower ends of the anesthetic gas flow meter 21 and the oxygen gas flow meter 22 are fixedly connected to the top of the adjacent outer cover shell 10 using flanges, such as Figure 5 shown.

[0057] A triangular tube 23 is fixedly installed on the top of the anesthetic gas flow meter 21 and the oxygen gas flow meter 22 using flanges, so that the gases flowing out of the anesthetic gas flow meter 21 and the oxygen gas flow meter 22 can be mixed inside the triangular tube 23. Figure 5 shown.

[0058] An anesthetic gas concentration monitor 24 is fixedly installed on the left side of the upper end of the triangular tube 23. The mixed gas is mixed into the interior of the anesthetic gas concentration monitor 24. At this time, the anesthetic gas concentration monitor 24 can monitor the concentration of the mixed anesthetic gas, so as to obtain the anesthetic gas concentration at this time, and the concentration data will be displayed on the display screen 5 for medical staff to view.

[0059] It should be noted that the anesthetic gas tank 6 , the oxygen gas tank 7 , the anesthetic gas concentration monitor 24 , and the subsequent respiratory gas concentration monitor 33 are all equipped with signal transmitting devices for displaying data on the display screen 5 .

[0060] An L-shaped pipe 25 is fixedly installed on the left side of the anesthetic gas concentration monitor 24. The left end of the L-shaped pipe 25 is located outside the main container box 1, and a first hose 26 is fixedly installed on the left rear end of the L-shaped pipe 25. Figure 2 As shown, during the use of the device, the first rotating rod 34 needs to be rotated, and the cooperation of the first hose 26 can prevent the first rotating rod 34 from being unable to rotate.

[0061] A through pipe 27 is fixedly installed at the rear end of the first hose 26, and a second hose 28 is fixedly installed on the top of the through pipe 27. A breathing mask 29 is fixedly installed at the rear end of the second hose 28. The breathing mask 29 and the second hose 28 are fixedly connected when in use. In order to ensure the safety of each patient, the rear ends of the breathing mask 29 and the second hose 28 are fixedly connected by a threaded rotation connection. A new breathing mask 29 can be replaced after use by a patient, thereby ensuring the safety of the patient.

[0062] A Y-shaped nasal inlet tube 30 is fixedly installed inside the breathing mask 29, and the front end of the nasal inlet tube 30 and the rear end of the second hose 28 are fixedly connected (when in use, the nasal inlet tube 30 and the second hose 28 are fixedly connected, and in the early stage of operation, the nasal inlet tube 30 and the second hose 28 are combined together in a plug-in manner to ensure that the nasal inlet tube 30 can be replaced later, thereby ensuring the safety of the patient). Then, cable ties 31 are symmetrically fixedly installed on the left and right sides of the breathing mask 29. When in use, the cable ties 31 can be used to fix the breathing mask 29 on the patient's face, so that the breathing mask 29 will not fall off, and to avoid the situation where medical staff press the breathing mask 29 with their hands for a long time, such as Figure 3 and Figure 4 shown.

[0063] Secondly, a connecting air pipe 32 is fixedly installed from the inside to the outside of the breathing mask 29 in an inclined manner, and a respiratory gas concentration monitor 33 is rotatably connected to the outside of the connecting air pipe 32. Figure 4 shown.

[0064] During use, the respiratory gas concentration monitor 33 can monitor the concentration of oxygen and anesthetic gas in the patient's exhaled gas, so that the obtained data can be displayed on the display screen 5, and then the servo motor 11 is started according to the concentration of the patient's exhaled gas, so as to adjust the amount of anesthetic gas or oxygen, thereby changing the mixing ratio of anesthetic gas and oxygen gas, thereby ensuring the safety of the patient and the safety of using anesthesia, and avoiding too much or too little.

[0065] Secondly, a first rotating rod 34 is rotatably installed on the left side surface of the main container box 1, wherein the through pipe 27 is fixedly installed inside the first rotating rod 34 so that it can rotate with the first rotating rod 34, and connecting plates 35 are rotatably installed on the left and right sides of the top of the first rotating rod 34, and the rotation connection position of the connecting plate 35 and the first rotating rod 34 adopts a damping rotation connection to avoid the connecting plate 35 from rotating on its own, and a U-shaped frame 36 is rotatably installed on the outer side of the top of the left and right connecting plates 35, and the U-shaped frame 36 is fixedly connected to the breathing hood 29 for supporting and carrying the breathing hood 29 for movement. It should be noted that the upper end of the through pipe 27 is located on the outer side of the first rotating rod 34 and can be bent and folded, so that the connecting plate 35 can adjust the angle of the upper end of the through pipe 27.

[0066] In addition, an air intake valve 37 is fixedly installed at the lower part of the front end surface of the anesthetic gas tank 6 and the oxygen gas tank 7. After the gas inside the anesthetic gas tank 6 and the oxygen gas tank 7 is used up, it can be replenished through the air intake valve 37.

[0067] Working principle: First, rotate the first rotating rod 34, the first rotating rod 34 rotates with the through tube 27, then adjust the connecting plate 35, the connecting plate 35 rotates with the U-shaped frame 36, adjust the U-shaped frame 36, the U-shaped frame 36 rotates with the breathing mask 29, the breathing mask 29 fits the patient's face and is fixed with a cable tie 31.

[0068] At this time, when using the cable tie 31, the nasal inlet tube 30 and the second hose 28 need to be plugged together, and the nasal inlet tube 30 is inserted into the patient's nasal cavity.

[0069] By pressing the corresponding operation button 4, the gas in the anesthetic gas tank 6 and the oxygen gas tank 7 starts to flow out in the corresponding proportion, passes through the chassis 13 and the gear plate 18 and enters the corresponding anesthetic gas flow meter 21 and the oxygen gas flow meter 22, so that the medical staff can know the current flow rate, and the mixed gas enters the anesthetic gas concentration monitor 24.

[0070] Then it enters the interior of the L-shaped pipe 25, then enters the interior of the first hose 26, and finally enters the through pipe 27, passes through the through pipe 27 to enter the interior of the second hose 28, passes through the second hose 28 to enter the interior of the nasal inlet 30, so that the patient can inhale when breathing.

[0071] The gas exhaled by the patient passes through the connecting trachea 32 and enters the interior of the respiratory gas concentration monitor 33. After floating out of the respiratory gas concentration monitor 33, the anesthetic gas concentration and oxygen concentration of the exhaled gas can be obtained. The corresponding servo motor 11 is started according to the concentration data to adjust the outflow of anesthetic gas or oxygen gas to obtain a new mixed gas.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
