Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to a pressure storage smoke exhaust purification system and method. Background Art

[0002] A large amount of surgical smoke is often produced in the operating room. That is, during the surgical operation, high-frequency electrocautery knives, laser knives, ultrasonic scalpels, high-speed drills, saw blades and instrument burrs destroy and vaporize tissue proteins and fat to form aerosols. Surgical smoke is composed of 95% water or water vapor and 5% cell fragments in the form of particles. The components contained in these 5% particles mainly include: blood and tissue fragments, harmful chemical components, active viruses, active cells, inactive particles, and substances that induce mutations. From many perspectives, surgical smoke not only affects the doctor's surgical field of view and the operation process, but also poses a risk of damaging the doctor's health. Therefore, there is an urgent need for a pressure-accumulated smoke exhaust purification system and method to improve the smoke exhaust efficiency and reduce the harm of surgical smoke. Summary of the invention

[0037] Example 1

[0038] like Figure 1 As shown, the pressure storage smoke exhaust purification system of this embodiment includes an air inlet 31, a negative pressure filter container 33, a negative pressure device 35 and an exhaust port 37 connected in sequence.

[0039] Among them, in this embodiment, the negative pressure filter container 33 can be a negative pressure filter bottle, which is filled with disinfectant liquid to eliminate particulate matter and some harmful gases contained in the smoke. The negative pressure filter container 33 is connected to an air inlet pipe 332 immersed in the liquid surface and an exhaust pipe 333 placed outside the liquid surface, wherein the air inlet pipe 332 is connected to the air inlet 31, the exhaust pipe 333 is connected to the negative pressure device 35, and the negative pressure device 35 is connected to the exhaust port 37.

[0040] Specifically, the process of completing smoke exhaust by the pressurized smoke exhaust purification system in this embodiment includes: closing the air inlet 31 of the negative pressure filter container 33, opening the negative pressure device 35, and extracting the air above the liquid surface of the negative pressure filter container 33. At this time, negative pressure is gradually formed in the negative pressure filter container 33. After a period of time, the switch of the air inlet pipe 332 of the negative pressure filter container 33 is opened, and the air inlet pipe 332 immediately inhales the surgical smoke from the air inlet 31.

[0041] The inhaled surgical smoke first enters the disinfectant liquid in the negative pressure filter container 33 to complete filtering and disinfection, and then enters the air above the liquid level in the negative pressure filter container 33, is sucked away by the negative pressure device 35 through the exhaust pipe 333, and is discharged from the exhaust port 37 to complete the smoke exhaust process.

[0042] It can be seen that the pressure storage smoke exhaust purification system of this embodiment generates negative pressure in the negative pressure filter container 33 through the negative pressure device 35, sucks air from the air inlet 31, and filters it in the disinfectant liquid inside the negative pressure filter container 33, thereby achieving faster removal of surgical smoke.

[0043] Furthermore, the system can also be provided with a control component, including a pressure sensor 4 and a controller. The controller is arranged between the air inlet 31 and the negative pressure filter container 33, and a main control board 2 can be selected to control the opening or closing of the air inlet pipe 332. The main control board 2 is also connected to the negative pressure device 35 to control the start or stop of the operation of the negative pressure device 35. The pressure sensor 4 is connected to the liquid surface of the negative pressure filter container 33 to continuously monitor the gas pressure above the liquid surface of the negative pressure filter container 33. The control component can also be increased with an air quality sensor 6, which is arranged behind the air filter element 36 to monitor the air quality after the smoke exhaust is completed.

[0044] Furthermore, the system may also be provided with an air filter element 36 between the negative pressure device 35 and the exhaust port 37 or in the exhaust port 37 to filter the gas exhausted from the negative pressure device 35 .

[0045] Furthermore, the system can also set a drying module 34 between the negative pressure filter container 33 and the negative pressure device 35. The drying module 34 includes multiple stages of drying tubes filled with different desiccants to dry the air after passing through the negative pressure filter container 33 to prevent the disinfectant from entering the negative pressure device 35 and causing contamination.

[0046] Furthermore, the system may also be provided with a disposable filter 8 at the air inlet 31 to perform primary filtration on the air entering the system.

[0047] Furthermore, the system may also be provided with an ultraviolet lamp 7 after the air filter element 36 to sterilize the air discharged from the system.

[0048] Furthermore, the system may also be provided with a display device, which may be a touch screen 1 connected to the main control board 2 to display the negative pressure monitored by the pressure sensor 4 and the air quality information monitored by the air quality sensor 6 .

[0049] Example 2

[0050] Based on the pressure storage smoke exhaust purification system in Example 1, this embodiment provides a pressure storage smoke exhaust purification system, including a display device, a control component, an air inlet 31, a negative pressure filter container 33, a drying module 34, a negative pressure device 35, an air filter element 36, an exhaust port 37, an air quality sensor 6, a disposable filter 8 and an ultraviolet lamp 7. The connection of the pressure storage smoke exhaust purification system in this embodiment is as follows Figure 2 shown.

[0051] Specifically, under the action of the negative pressure device 35 sucking air, the gas passes through the disposable filter 8, enters the pressure storage smoke exhaust purification system from the air inlet 31, and then enters the negative pressure filter container 33 above the liquid level through the air inlet pipe 332. The negative pressure filter container 33 of this embodiment can select a negative pressure filter bottle, and then leaves the negative pressure filter container 33 through the exhaust pipe 333 to enter the drying module 34, and then is drawn into the negative pressure device 35, continues to pass through the air filter element 36, and after leaving the air filter element 36, the air quality sensor 6 collects information and receives the irradiation and disinfection of the ultraviolet lamp 7, and is discharged from the pressure storage smoke exhaust purification system from the exhaust port 37.

[0052] Among them, the air inlet 31, the negative pressure filter container 33, the drying module 34, the negative pressure device 35, the air filter element 36 and the exhaust port 37 are all connected by an air hose. The air quality sensor 6 is arranged after the air filter element 36, and can be arranged between the air filter element 36 and the exhaust port 37, or at the exhaust port 37.

[0053] Specifically, in this embodiment, the display device is set as a touch screen 1, and the control component includes a main control board 2, a pressure sensor 4 and a solenoid valve 32. The touch screen 1 is connected to the main control board 2 through a serial port, and the main control board 2 is connected to the solenoid valve 32, the negative pressure device 35 in the gas circuit component and the pressure sensor 4 through a circuit, and the pressure sensor 4 is connected to the air above the negative pressure filter container 33 in the gas circuit component. Among them, the solenoid valve 32 is set in the air inlet pipe 332 of the negative pressure filter container 33, as a switch of the air inlet pipe 332.

[0054] Specifically, the process of exhausting smoke by the pressure storage smoke exhaust purification system of this embodiment is as follows:

[0055] When the solenoid valve 32 is closed, the negative pressure device 35 is turned on to evacuate air, and negative pressure is gradually formed above the liquid surface of the negative pressure filter container 33. The solenoid valve 32 is opened after a preset time. Since the pressure in the negative pressure filter container 33 is significantly lower than the atmospheric pressure, the surgical smoke instantly enters the disinfectant liquid in the negative pressure filter container 33 from the exhaust port 37 for filtration, and then enters the negative pressure filter container 33 above the liquid surface to balance the pressure. At this time, since the negative pressure device 35 continues to evacuate air, the surgical smoke above the liquid surface of the negative pressure filter container 33 absorbs moisture through the drying module 34, passes through the negative pressure device 35, enters the air filter element 36 to further filter out particulate matter and harmful gases, and then passes through the air quality sensor 6 to collect information and is discharged from the exhaust port 37.

[0056] Furthermore, the opening and closing of the solenoid valve 32 and the operation of the negative pressure device 35 are controlled by the main control board 2, and the main control board 2 receives the instructions received by the touch screen 1 and completes the control through electrical signals. Preferably, the negative pressure device 35 can also be turned on or off by a foot switch.

[0057] Furthermore, during the smoke exhaust process, the air above the liquid level of the negative pressure filter container 33 is connected to the pressure sensor 4 to monitor the pressure in real time. In this embodiment, the air above the liquid level of the negative pressure filter container 33 is connected to the pressure sensor 4 through a pressure measuring tube 331. The pressure information monitored by the pressure sensor 4 and the air quality information monitored by the air quality sensor 6 are both sent to the main control board 2, and the main control board 2 converts this information into visual information and sends it to the touch display screen 1 for display, so that the user can input instructions based on this information.

[0058] Furthermore, the process of filtering the surgical smoke by the negative pressure filter container 33 is based on the fact that the disinfectant contained in the liquid surface of the negative pressure filter container 33 can filter and eliminate the particulate matter and some harmful gases contained in the inhaled smoke. Preferably, the negative pressure filter container 33 is washable and easy to clean.

[0059] The drying module 34 dries the surgical smoke after filtering through the negative pressure filter container 33. The drying module 34 includes a multi-stage drying tube, including a first-stage drying tube 341 and a second-stage drying tube 342. Different desiccants are contained in each drying tube to dry the water vapor in the air after passing through the negative pressure filter container 33, so as to prevent the disinfectant from entering the subsequent device to cause damage and pollution, ensure the separation of dry and wet in the system, thereby protecting the safety of the circuit, extending the service life of each device, and ensuring the smoke exhaust effect. Preferably, the drying module 34 also includes a drying module replacement window 340, which is used to achieve replaceability and easy replacement.

[0060] The air quality information collected by the air quality sensor 6 includes information such as the content of particulate matter and volatile organic matter in the exhaust gas, which serves as feedback on whether the smoke exhaust treatment is complete.

[0061] The process of further filtering the surgical smoke by the air filter 36 is based on the fact that the air filter 36 includes a fiber layer and an adsorption layer, wherein the fiber layer can capture tiny particles in the air, such as bacteria, viruses, etc., and the adsorption layer can absorb and remove harmful gases and odors in the air. The air filter 36 has an air filter replacement window 361, which determines whether it needs to be replaced based on the air quality information monitored by the air quality sensor 6.

[0062] During the process of air extraction by the negative pressure device 35 , the power of the negative pressure device 35 is adjustable, so that the smoke exhaust speed can be controlled according to demand, providing more application scenarios for the pressure storage smoke exhaust purification system.

[0063] The disposable filter 8 is arranged at the air inlet 31 to perform primary filtration on the air entering the system, and the ultraviolet lamp 7 is arranged at the exhaust port 37 to perform secondary disinfection on the air discharged from the system. The smoke exhaust quality can be further optimized by arranging these two components.

[0064] In summary, this embodiment is based on the pressure storage smoke exhaust purification system described in Example 1, and adds a touch screen 1, a main control board 2, a pressure sensor 4, a pressure measuring tube 331, a drying module 34, an air filter element 36 and an air filter element replacement window 361, an air quality sensor 6, an ultraviolet lamp 7 and a disposable filter 8. Among them, the addition of multiple filtering links optimizes the filtering effect of the filtering system, and the setting of the control component and the display device not only visualizes the information in the smoke exhaust process of the system, but also facilitates the user to control the pressure storage smoke exhaust purification system according to the information, thereby generally improving the smoke exhaust efficiency of the pressure storage smoke exhaust purification system.

[0065] Example 3

[0066] The present embodiment provides a pressurized smoke exhaust purifier, comprising a movable chassis, in which the pressurized smoke exhaust purification system described in Example 2 is installed, so as to meet the needs of users to move the purifier in an operating room or other places, thereby making the purifier more convenient to use and having a wider range of application scenarios.

[0067] Specifically, Figure 3 As shown, it includes a touch display screen 1, a handle, an air inlet 31, a disposable filter 8, a drying module 34, and a roller. Among them, the touch display screen 1 is arranged at the top of the chassis shell 5, the handle for dragging the chassis to move is arranged at one side of the top of the chassis shell 5, the air inlet 31 in the form of a long pipe extends from the chassis shell 5, the disposable filter 8 is arranged at the end of the air inlet 31 close to the chassis shell 5, the negative pressure filter container 33 is arranged inside the chassis, connected to the air inlet pipe 332, the exhaust pipe 333 and the pressure measuring pipe 331, the drying module 34 is located inside the chassis, arranged below the negative pressure filter container 33, and the roller is located at the bottom of the chassis for moving the chassis.

[0068] like Figure 4 As shown, the case further includes an exhaust port 37, an ultraviolet lamp 7, an air quality sensor 6, and a foot switch. The exhaust port 37 is designed as an exhaust cavity 371, in which the ultraviolet lamp 7 and the air quality sensor 6 are arranged, the air filter 36 and the air filter replacement window 361 are arranged below the exhaust port 37, and the foot switch is located between the rollers at the bottom of the case shell 5.

[0069] Furthermore, the interior of the chassis also includes a negative pressure device 35 located between the drying module 34 and the air filter 36, a main control board 2 connected to the touch display screen 1, a solenoid valve 32 connected to the air intake pipe 332, and a pressure sensor 4 connected to the pressure measuring pipe 331. These components can be placed arbitrarily in the chassis without affecting the exhaust effect of the pressure storage exhaust purifier and satisfying the rationality of assembly.

[0070] Specifically, the process of exhausting smoke by the pressure-accumulating smoke purifier includes: before the operation begins, the chassis of the pressure-accumulating smoke purifier is moved to a position where the air inlet pipe 332 is easy to absorb surgical smoke. When the solenoid valve 32 is closed, the negative pressure device 35 is turned on to extract air, and negative pressure is gradually formed above the liquid surface of the negative pressure filter container 33. After a preset time, the solenoid valve 32 is opened. Because the pressure in the negative pressure filter container 33 is significantly lower than the atmospheric pressure, the surgical smoke instantly enters the chassis from the air inlet 31, enters the disinfectant liquid in the negative pressure filter container 33 through the air inlet pipe 332 to complete the filtration, and then enters the air above the liquid surface to balance the pressure. At this time, because the negative pressure device 35 continues to exhaust air, the surgical smoke above the liquid surface of the negative pressure filter container 33 absorbs moisture through the drying module 34, and enters the air filter element 36 through the negative pressure device 35 to further filter out particulate matter and harmful gases, and then after the air quality sensor 6 collects information, it is discharged from the exhaust port 37.

[0071] Furthermore, during the operation, the user can obtain the negative pressure in the negative pressure filter container 33 and the final air quality after smoke exhaust according to the touch screen 1 on the chassis, and then input instructions or step on the foot switch to control the pressure storage smoke exhaust purification system according to the smoke exhaust demand. The user can also adjust the position of the chassis as needed, and then adjust the position of the air inlet 31 to inhale the surgical smoke, to ensure that the pressure storage smoke exhaust purifier has the best smoke exhaust effect.

[0072] Example 4

[0073] This embodiment provides a pressurized smoke exhaust purification method based on the pressurized smoke exhaust purification system of Embodiment 1, which specifically includes any one or a free combination of three working modes, wherein the three working modes are a normal working mode, a preparatory working mode and a circulating pressure storage working mode.

[0074] Among them, Figure 5As shown, the process of the preparatory working mode includes:

[0075] S501, close the switch solenoid valve 32 of the intake pipe.

[0076] S502, turning on the negative pressure device 35 to store pressure.

[0077] S503, open the switch solenoid valve 32 of the air intake pipe to exhaust smoke.

[0078] Specifically, the negative pressure device 35 is turned on to evacuate air while the solenoid valve 32 is closed for a preset time so that the air pressure above the liquid surface of the negative pressure filter container 33 is negative pressure. When it is necessary to exhaust smoke from the air, the solenoid valve 32 is opened, and the air inlet pipe 332 of the negative pressure filter container 33 inhales air from the air inlet 31. After a period of transition, it enters the normal working mode. This mode can achieve the effect of instantly clearing a large amount of surgical smoke.

[0079] like Figure 6 As shown, the process of normal working mode is similar to the working mode of common smoke exhaust equipment, including:

[0080] S601, open the switch solenoid valve 32 of the intake pipe.

[0081] S602, start the negative pressure device 35 to exhaust smoke.

[0082] like Figure 7 As shown in FIG. 1 , the process of the circulating pressure storage working mode includes:

[0083] S701, turn on the negative pressure device 35.

[0084] S702: Control the opening and closing of the air intake pipe according to an open-close cycle to exhaust smoke.

[0085] Specifically, the user is first required to pre-set the opening and closing cycle of the solenoid valve 32 on the touch display screen 1, that is, the solenoid valve 32 is opened for a period of time and then closed for a period of time, and the negative pressure device 35 is kept open to perform the opening and closing cycle of the solenoid valve 32. This working mode is equivalent to periodically closing the solenoid valve 32 for a short time in the normal working mode. During the time when the solenoid valve 32 is briefly closed, a large negative pressure is formed above the liquid level of the negative pressure filter container 33, so that when the solenoid valve 32 is opened again, the surgical smoke can be quickly inhaled for smoke exhaust treatment. Compared with the working modes of other smoke exhaust equipment, this mode can increase the smoke exhaust speed by 30% at the same smoke exhaust flow rate. Preferably, based on actual test data, in the opening and closing cycle of the solenoid valve 32, the opening time of the solenoid valve 32 should be much greater than the closing time, so as to ensure the working efficiency of the pressure storage smoke exhaust purification system over a long period of time.

[0086] In summary, the pressure storage smoke exhaust purification system and method provided by the present invention forms a negative pressure in the negative pressure filter container. When in use, the surgical smoke is inhaled to balance the pressure, which can achieve more efficient smoke exhaust and reduce the harm of surgical smoke.

[0087] It should be pointed out that, according to the needs of implementation, the various steps / components described in this application can be split into more steps / components, and two or more steps / components or partial operations of steps / components can be combined into new steps / components to achieve the purpose of the present invention.

[0088] The order of execution of each step in the above embodiment does not mean the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

[0089] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
