Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical surgical abdominal cleansing device. Background Technology

[0002] With the widespread adoption of laparoscopic surgery, the use of energy devices such as monopolar electrosurgical units, bipolar electrosurgical units, ultrasonic scalpels, laser scalpels, and Ligasure is becoming increasingly common, further promoting the application of laparoscopic surgery. However, the direct harm and persistent threat posed to medical personnel by the fumes generated during the use of these devices has long been neglected and not effectively addressed. Surgical professionals have conducted extensive research on the composition and hazards of fumes generated during laparoscopic surgery, generally agreeing that 95% of surgical fumes are water vapor, while the remaining 5% can be divided into formed elements and intangible components. Formed elements, classified by biological properties, mainly include particles such as active proteins, active viruses, and active cells; classified by aerodynamic diameter, they mainly include dust, PM10, PM2.5, and PM1.0. Intangible components are primarily harmful chemical gases, such as formaldehyde, acrylonitrile, carbon monoxide, phenols, benzene, and benzene derivatives. The toxicity, infectivity, and carcinogenicity of these 5% components have been extensively documented in the literature, and their hazards are multifaceted. If these fumes are not promptly removed, they will severely impair the surgeon's vision, posing a significant risk to surgical safety. Directly releasing them into the room via laparoscopic trocars will undoubtedly cause direct harm and a lasting threat to medical personnel. Although the proper use of various energy devices can reduce surgical fumes, their generation cannot be completely eliminated. Medical protective masks can block larger particles, such as PM2.5, but their effectiveness against the more harmful PM1.0 and various hazardous chemical gases is very limited. The use of positive-pressure protective masks or the construction of smoke evacuation or purification systems has not been widely adopted in China due to high costs, complex structures, and difficult construction. The most common method is to directly use a central suction device, including laparoscopic surgical suction instruments or a separate tubing connected to a trocar, using a flexible tube of appropriate diameter to directly remove the smoke. While these methods are convenient, an efficient smoke extraction system should meet three basic requirements: the system should not interfere with the surgeon's surgical activities; it should have sufficient negative pressure to ensure smoke removal; and it should effectively filter the smoke to make the environment safer. Direct suction using laparoscopic surgical instruments affects the surgeon's operation due to the need for constant instrument changes, and direct suction also poses certain environmental hazards. Suction using a separate tubing connected to a trocar also presents environmental issues. Furthermore, it has been found that this method results in significant CO2 waste.

[0003] Large amounts of smoke are generated during abdominal surgery. This smoke is typically treated simply before being released directly into the operating room. However, this smoke actually contains a large number of active viruses and harmful chemical gases. Simple treatment is insufficient to eliminate the viruses, and the smoke released into the operating room poses a threat to the health of medical staff. Existing abdominal cleansing devices on the market lack multi-layer filtration, employ unscientific filtration methods, have unclear filter lifespans, and are extremely inconvenient to replace, easily leading to repeated contamination during subsequent uses.

[0004] Existing surgical fumigation devices suffer from problems such as overly simplistic filtration methods, poor filtration efficiency, unreasonable filter arrangement, and the continued presence of large amounts of viruses and inhalable particulate matter after gas filtration. To address these issues, this invention proposes a medical surgical fumigation device. The design and application of this device can effectively eliminate smoke generated during laparoscopic surgery, protecting the health of doctors and patients, and reducing environmental pollution. Furthermore, through an intelligent monitoring and management system, the device can monitor its operational status in real time, ensuring efficient operation. Compared to traditional smoke treatment methods, this invention provides a safer, more efficient, and environmentally friendly solution.

[0005] In the future, with the continuous advancement of surgical techniques and medical equipment, medical surgical abdominal purification devices will be used in more medical settings, making a greater contribution to improving surgical quality and protecting the health of medical personnel. At the same time, through continuous optimization and improvement of the design of the abdominal purification device, it is expected to further enhance its filtration and purification effects, achieving the effective removal of more harmful substances and striving to create a safer and more comfortable surgical environment. Summary of the Invention

In the above technical solution, the gas enters the disinfection box 1 through the first exhaust pipe 5 and then enters the drying box 2 through the first exhaust pipe 5. While flowing, the gas can be disinfected by the disinfectant water in the disinfection box 1. Then the gas is filtered through the first filter plate 13 and the second filter plate 14. The filtered gas enters the gas filter cartridge 3 through the second exhaust pipe 6 and the second intake pipe 9 for further disinfection and filtration. The filtered gas can be stored and used or directly discharged. Example

[0025] Reference Figures 1-4 Medical surgical abdominal cleansing device, including: The disinfection box 1 has a drying box 2 fixedly connected to its bottom for drying the gas. The top of the disinfection box 1 has a first air inlet pipe 4 for air intake and a first air outlet pipe 5 for air outlet. The other end of the first air outlet pipe 5 is connected to the drying box 2. A gas filter cartridge 3 has a second air inlet pipe 9 fixedly connected to one end of it, a second air outlet pipe 6 fixedly connected to one side of the drying chamber 2, a pressure pump 7 between the drying chamber 2 and the gas filter cartridge 3, and the ends of the second air inlet pipe 9 and the second air outlet pipe 6 that are close to each other are respectively connected to the inlet and outlet ends of the pressure pump 7. A third air outlet pipe 10 is fixedly connected to the other end of the gas filter cartridge 3. The inner wall of the drying oven 2 is fixedly connected with a first filter plate 13 and a second filter plate 14. The first filter plate 13 is located on top of the second filter plate 14 and is used to filter the gas. One end of the gas filter cartridge 3 is equipped with an ultraviolet lamp 16 for gas sterilization. The inner wall of the gas filter cartridge 3 is provided with two first filter screens 18 and second filter screens 19 for further gas filtration. A high-voltage electrostatic sterilization screen 17 for further gas sterilization is fixedly connected to the inner wall of the gas filter cartridge 3. In the above technical solution, the gas enters the disinfection box 1 through the first exhaust pipe 5 and then enters the drying box 2 through the first exhaust pipe 5. While flowing, the gas can be disinfected by the disinfectant water in the disinfection box 1. Then the gas is filtered through the first filter plate 13 and the second filter plate 14. The filtered gas enters the gas filter cartridge 3 through the second exhaust pipe 6 and the second intake pipe 9 for further disinfection and filtration. The filtered gas can be stored and used or directly discharged.

[0026] Reference Figure 1 and Figure 3 The first filter plate 13 is provided with color-changing silica gel drying particles for filtering water vapor in the gas. In the above technical solution, the color-changing silica gel drying particles can adsorb the active proteins and active viruses attached to the water vapor liquid particles onto the color-changing silica gel drying particles, causing the active proteins to dehydrate and die.

[0027] Reference Figure 1 and Figure 3 The second filter plate 14 is provided with activated carbon particles for adsorbing harmful components in the gas. In the above technical solution, the activated carbon particles can adsorb harmful chemical components such as formaldehyde, acrylonitrile, carbon monoxide, phenols, benzene, and benzene series compounds contained in the gas.

[0028] Reference Figure 1 and Figure 4 The ultraviolet lamp 16 is cylindrically fixed to one end of the gas filter cartridge 3. The second air inlet pipe 9 extends into the ultraviolet lamp 16. The ultraviolet lamp 16 is a UVC lamp. The high-voltage electrostatic sterilization mesh 17 is located on one side of the ultraviolet lamp 16. In the above technical solution, a high-power UVC lamp is selected for the ultraviolet lamp 16. The high energy of UVC with a wavelength of 254nm can break the double helix of DNA and RNA, preventing cell regeneration and loss of self-replication ability, thereby achieving inactivation and disinfection of bacteria and viruses. It can kill all microorganisms, including bacteria, tuberculosis bacteria, viruses, spores, fungi, and active cells.

[0029] Reference Figure 1 and Figure 4The first filter 18 is an H13 HEPA filter, and the second filter 19 is a graphene filter. The second filter 19 is located between the two first filters 18. In the above technical solution, the H13 HEPA filter filters out particulate matter formed during the operation, such as dust, PM2.5, PM10, PM1.0 and other particles. Then the gas passes through an activated carbon filter to further remove residual odors and adsorb formaldehyde, acrylonitrile, carbon monoxide, phenols, benzene and benzene series compounds. Finally, it passes through the H13 HEPA filter for final filtration and to prevent backflow pollution.

[0030] Reference Figure 1 and Figure 2 The first air inlet pipe 4 extends into the disinfectant water inside the disinfection box 1, and the first air outlet pipe 5 is located inside the disinfection box 1 at a position higher than the disinfectant water level. In the above technical solution, the setting of the first air inlet pipe 4 and the first air outlet pipe 5 enables the gas to fully contact the disinfectant water, which facilitates simple disinfection of the gas by the disinfectant water.

[0031] Reference Figure 1 and Figure 3 The first exhaust pipe 5 extends to one end of the drying chamber 2, which is located above the first filter plate 13. The second exhaust pipe 6 is located inside the drying chamber 2, with one end located below the second filter plate 14. In the above technical solution, the gas can be filtered step by step by setting the first filter plate 13 and the second filter plate 14.

[0032] Reference Figures 1-7A front-end sensor module 15 is provided between the drying chamber 2 and the gas filter cartridge 3. A rear-end sensor module 11 and a display control module 12 are provided on one side of the gas filter cartridge 3. Both the front-end sensor module 15 and the rear-end sensor module 11 are connected to the display control module 12 through wires. A solenoid valve 8 is provided on the second exhaust pipe 6. The solenoid valve 8 is connected to the front-end sensor module 15 through wires. In the above technical solution, the front-end sensor module 15 is placed after the coarse filter. The front-end sensor module 15 includes a pressure sensor, a PM2.5 sensor, and a TVOC sensor. The pressure sensor detects the air pressure to determine whether surgical waste gas has entered the machine. If so, the rear-end pressurization pump 7 and the solenoid valve 8 start working to facilitate the gas to pass through the filter screen for purification. The PM2.5 sensor and the TVOC sensor detect the concentration of gaseous pollutants in real time. The gas passes through the HEPA filter screen to filter the corresponding PM2.5 pollutants and TVOC pollutants. The rear sensor module 11 is located on one side of the third air outlet pipe 10 and includes a gas pressure sensor and a CO2 concentration sensor. The gas pressure sensor and CO2 concentration sensor detect the air pressure and CO2 concentration at the rear of the filter. By determining whether the air pressure and CO2 concentration are consistent with the CO2 air pressure supplied for the operation, the auxiliary air pump is adjusted to change the speed at which the gas passes through the filter, so that the air pressure at the rear is kept within the range required for the operation.

[0033] The working principle and usage process of this technical solution are as follows: gas enters the disinfection box 1 through the first air inlet pipe 4, and the water vapor and water-soluble components in the smoke are filtered out by the disinfectant water, which can also perform preliminary disinfection of the gas. After disinfection and filtration, the gas enters the drying chamber 2 through the first exhaust pipe 5. The color-changing silica gel drying particles and activated carbon particles on the first filter plate 13 and the second filter plate 14 can adsorb the active proteins and active viruses attached to the water vapor liquid particles onto the drying particles, causing the active proteins to dehydrate and die. The activated carbon particles can adsorb harmful chemical components such as formaldehyde, acrylonitrile, carbon monoxide, phenols, benzene, and benzene series compounds contained in the gas. The pressurization pump 7 is started by controlling the front-end sensor module 15, which draws the gas in the drying chamber 2 into the gas filter cartridge 3. Because the gas filter cartridge 3 is sealed and the gas flow rate is relatively fast, the high energy of the ultraviolet lamp 16 can break the DNA and RNA double helix chains, making the cells unable to regenerate and lose their ability to self-replicate, thereby achieving the inactivation and disinfection of bacteria and viruses. It can kill all microorganisms, including bacteria, tuberculosis bacteria, viruses, spores and fungi, and active cells.

[0034] After passing through the ultraviolet lamp 16, the gas enters the high-voltage electrostatic sterilization grid 17. The high-voltage electrostatic sterilization grid 17 can capture 0.01μm particles through electrostatic adsorption and effectively kill viruses adsorbed on the grid through high-voltage electrostatic. Then, the micro-particulate matter formed during the first filter 18 filtration process, such as dust, PM2.5, PM10, PM1.0 and other particles, is filtered out. The gas then passes through the second filter 19 to further remove any remaining odors and adsorb formaldehyde, acrylonitrile, carbon monoxide, phenols, benzene, and benzene compounds. Then it passes through the first filter screen 18 for final filtration and to prevent backflow contamination; Finally, the gas is either discharged or introduced into other containers through a one-way valve. In this way, the discharged gas has been filtered to remove various active viruses and harmful chemical components such as formaldehyde and acrylonitrile that may be present in the surgical smoke, and what is discharged is pure CO2 gas.

[0035] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
