Description

Smoke purification smoking device

Technical Field

The utility model relates to the technical field of surgical auxiliary instruments, in particular to a smoke purification smoking device.

Background technique

During surgery, the use of energy devices such as monopolar electrosurgery, ultrasonic scalpels, and laser scalpels will produce smoke. The smoke here refers to a mixture of aerosols and steam produced by surgical cutting. These substances contain harmful substances, so the smoke needs to be purified.

A Chinese authorized patent with announcement number CN210494215U discloses a laparoscopic surgical smoke purifier, including a support, an exhaust pipe and a connecting pipe. Four sets of rollers are fixedly installed at the four corners of the bottom end of the support, a push-pull handle is fixedly connected to the upper right end of the support, a liquid collector is fixedly installed on the left side of the top end of the support, a condenser is installed on the liquid collector, a transfer block is connected to the left side of the top end of the liquid collector through the exhaust pipe, a gripping handle is provided at the bottom end of the transfer block, an air inlet pipe joint is fixedly connected to the right end of the transfer block, a purification device is connected to the middle part of the top end of the liquid collector through the connecting pipe, the purification device is fixedly installed in the middle part of the top end of the support, an outlet pipe is installed at the lower left end of the purification device, the outlet pipe is connected to the exhaust pump, and the exhaust pump is fixedly installed on the right side of the top end of the support.

The above-mentioned smoke purifier can be easily moved by the rollers, and the condenser can quickly cool the smoke to condense the water vapor in the smoke. The gripping handle is helpful for medical staff to control the device to extract the smoke in the abdominal cavity.

However, there are some defects when using it:

At present, most hospitals adopt central negative pressure for smoke extraction, and use a vacuum pump as a negative pressure generating element in the smoke purification process, which consumes a lot of energy. In addition, the above-mentioned laparoscopic surgery smoke purifier only adsorbs smoke through activated carbon, which cannot effectively remove the bacteria in the smoke. In addition, only a single filtering unit is provided, which cannot effectively filter the smoke thoroughly. At the same time, after the smoke is adsorbed, it is directly discharged into the operating room, which still causes certain pollution to the air in the operating room.

For this reason we propose a smoke purification smoking device.

Please refer to Figures 1 to 3, in the embodiment of the present utility model,

The smoke purification smoking device is composed of a base 1, a filtering and sterilizing component and an adsorption mechanism.

Among them, the filtering and sterilizing component includes a sterilizing filter box 3, which is fixedly installed on the top of the base 1. An adsorption component for adsorbing particles in the smoke is installed at the upper end of the sterilizing filter box 3. The adsorption component includes a positive plate 11 and a negative plate 13. The positive plate 11 and the negative plate 13 are respectively fixedly installed on the inner walls of the sterilizing filter box 3 on both sides. A plurality of groups of ultraviolet sterilization lamps 12 are fixedly installed inside the sterilizing filter box 3 below the adsorption component. By adopting the above technical solution, when in use, the positive plate 11 and the negative plate 13 are energized, so that the positive plate 11 and the negative plate 13 are A strong electric field is formed between the plates 13. Due to corona discharge on the negative plate 13, the gas is ionized. Under the action of the electric field force, the negatively charged gas ions move toward the positive plate 11, and collide with the particles in the smoke during the movement, making the particles negatively charged. Under the action of the electric field force, the negatively charged particles move toward the positive plate 11, and after reaching the positive plate 11, the negative charge is released, and the particles are deposited on the positive plate 11, thereby realizing the function of adsorbing most of the particles in the smoke. The smoke treated by the adsorption component will be irradiated by the ultraviolet sterilization lamp 12, and then the smoke will be sterilized.

In order to facilitate the inspection and cleaning of the positive plate 11, the ultraviolet sterilization lamp 12 and the negative plate 13 in the sterilization filter box 3, the top of the sterilization filter box 3 is opened, and the top of the sterilization filter box 3 is fixed with a top cover 4 by bolts. In order to facilitate the suction of smoke, a suction port 8 is opened on one side of the top cover 4, and the suction port 8 is rotatably connected to a smoke exhaust pipe 5. The end of the smoke exhaust pipe 5 away from the suction port 8 is detachably connected with a smoking pipe 6 made of stainless steel. The smoking pipe 6 and the smoke exhaust pipe 5 are interference fit. After the operation, the smoking pipe 6 can be disassembled and sent to the disinfection and cleaning room for cleaning and disinfection for reuse.

Specifically, in order to further improve the smoke suction effect and suction range, a trumpet-shaped smoke hood 7 is provided at the air inlet of the smoke pipe 6 .

Specifically, a filter screen 9 is arranged between the top cover 4 and the sterilization filter box 3. A supporting frame 10 for supporting the filter screen 9 is arranged at the upper end of the interior of the sterilization filter box 3. The filter screen 9 can filter larger particles of smoke, thereby reducing the number of smoke particles adsorbed on the adsorption component and extending the service life of the adsorption component.

Among them, the adsorption mechanism includes an adsorption box 14, one end of the adsorption box 14 is connected to the lower end of the sterilization filter box 3, the interior of the adsorption box 14 is filled with activated carbon, and one end of the adsorption box 14 is connected to a connecting nozzle 16 connected to the central negative pressure of the hospital. The activated carbon arranged in the adsorption box 14 can further filter and adsorb the smoke after filtering and sterilization.

Specifically, in order to facilitate the cleaning and replacement of the activated carbon in the adsorption box 14, a plugging cover 15 is fixedly installed on the side of the adsorption box 14 away from the sterilization filter box 3 by bolts. The plugging cover 15 is connected to the connecting nozzle 16. The activated carbon in the adsorption box 14 can be replaced by removing the plugging cover 15.

Specifically, in order to facilitate the control of the positive plate 11, the negative plate 13 and the ultraviolet sterilization lamp 12, a power box 17 for providing a stable power supply is fixedly installed on the top of the base 1, and a button 18 for controlling the adsorption component and the ultraviolet sterilization lamp 12 switch is provided on the power box 17.

Specifically, in order to facilitate the user to quickly understand the current operating status of the adsorption component and the ultraviolet sterilization lamp 12, an indicator light 19 for indicating whether the adsorption component and the ultraviolet sterilization lamp 12 are operating is provided on one side of the power box 17.

In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

Working principle: Move the smoking tube 6 to the surgical position, and then connect the connecting nozzle 16 to the hospital's central negative pressure system to form a negative pressure environment in the sterilization filter box 3 and the adsorption box 14, and then turn on the adsorption component and the ultraviolet sterilization lamp 12. The smoke generated during the operation passes through the smoking tube 6 and the exhaust pipe 5 into the sterilization filter box 3. The smoke is first preliminarily filtered by the filter net 9, and then filtered for the second time by the adsorption component to effectively remove harmful particles in the smoke. The smoke after the second filtration passes through the ultraviolet sterilization lamp 12 area for ultraviolet sterilization operation. The sterilized smoke is then adsorbed and filtered again by activated carbon and discharged to the outside by the hospital's central negative pressure system.
