Description

Technical Field

[0001] The invention relates to the technical field of anesthesia waste gas treatment in operating rooms, and in particular to an anesthesia waste gas mask collection device in an operating room. Background Art

[0002] With the continuous development of medical technology, anesthesia is used more and more widely in surgery. However, the emission of anesthetic waste gas has also attracted people's attention. In the operating room, anesthetic waste gas mainly comes from the gas containing anesthetic drugs exhaled by the patient. If these waste gases are directly discharged into the air without effective treatment, they will not only cause health hazards to medical staff in the operating room, but also pollute the environment. Long-term exposure to anesthetic waste gas may cause medical staff to experience symptoms such as headaches, fatigue, nausea, etc., and may even cause damage to the nervous system, reproductive system, etc.

[0003] At present, there are two main methods for treating waste anesthesia gas. One is to directly discharge the waste gas to the outdoors, but this method will pollute the atmospheric environment and is difficult to implement in some operating rooms that do not have good ventilation conditions. The other is to use a simple filtering device to treat the waste gas, but these filtering devices often have limited filtering effects and cannot effectively remove harmful substances in the waste gas. In addition, the existing anesthetic waste gas treatment devices also have some shortcomings in structural design. For example, the filter components of some devices are inconvenient to replace, which increases maintenance costs and time; the purification effect of some devices is not thorough enough, and the discharged gas may still contain a certain amount of harmful substances; and some devices are large in size, occupy a lot of space, and are not convenient for installation and use in operating rooms.

[0004] Therefore, in order to effectively solve the emission problem of anesthetic waste gas in the operating room and protect the health of medical staff and the environment, a new type of anesthetic waste gas mask collection device for the operating room is needed. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose an operating room anesthesia waste gas mask collection device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An operating room anesthesia waste gas mask collection device comprises a filter box, an air inlet pipe and an air outlet pipe are symmetrically arranged on the side wall of the filter box, a mask is installed on the air inlet pipe through a connecting hose, a first air pump, a purifier and a liquid pump are installed in sequence on the upper surface of the filter box, the air outlet pipe is connected to the first air pump through a first connecting pipe, a mixing box is installed at the air outlet end of the first air pump through a second connecting pipe, and the mixing box is connected to the purifier, and the water inlet end of the liquid pump is connected to the purifier, and the water outlet end of the liquid pump is connected to the mixing box; The outer wall of the purifier is connected with an exhaust pipe, the exhaust pipe is connected with the second air pump through a third connecting pipe, and the second air pump is installed on the outer wall of the filter box.

[0007] In the above-mentioned operating room anesthesia waste gas mask collection device, a sealing door is symmetrically installed on the filter box through a hinge, and a plurality of guide plates are equidistantly and staggeredly arranged in the filter box.

[0008] In the above-mentioned operating room anesthesia waste gas mask collection device, a processing plate is slidably connected to the side wall of each guide plate; Wedge-shaped bars are installed on both side walls of each processing plate, a wedge-shaped slide groove is opened on the guide plate, and each wedge-shaped bar is slidably connected in the wedge-shaped slide groove corresponding to the position.

[0009] In the above-mentioned operating room anesthesia waste gas mask collection device, the mixing box is connected with an air inlet pipe and a liquid inlet pipe, and one end of the second connecting pipe is connected to the air inlet pipe, and the water outlet end of the liquid pump is connected to the liquid inlet pipe through the liquid connecting pipe.

[0010] In the above-mentioned operating room anesthesia waste gas mask collection device, the purifier includes a liquid holding portion, and the liquid holding portion is installed on the upper end surface of the filter box. The liquid holding portion contains purified liquid, and the liquid holding portion is connected to a mixing purification portion. A plurality of through holes are evenly opened on the mixing purification portion, and each through hole is located in the mixing box.

[0011] In the above-mentioned operating room anesthesia waste gas mask collection device, a motor is installed on the outer wall of the mixing and purification part, and the output shaft of the motor extends into the mixing and purification part and is installed with a pushing frame.

[0012] In the above-mentioned operating room anesthesia waste gas mask collection device, the pushing frame includes a pushing cylinder, and the pushing cylinder is installed on the output shaft of the motor. Multiple pushing plates are evenly installed on the outer wall of the pushing cylinder, and the mixing and purification part is divided into multiple purification areas by the pushing plates.

[0013] In the above-mentioned operating room anesthesia waste gas mask collection device, the mixing box corresponds to the outside of one of the purification areas.

[0014] Compared with the prior art, the present invention has the following beneficial effects: Multiple guide plates are set in the filter box to guide the exhaust gas to flow in an equidistant and staggered path, which prolongs the residence time of the exhaust gas in the filter box and increases the contact time and contact area between the exhaust gas and the treatment plate. The wedge strips on both sides of the treatment plate cooperate with the wedge-shaped slides on the guide plate and the inner wall of the filter box to facilitate the sliding installation and removal of the treatment plate on the guide plate. The wedge-shaped structure can also play a certain positioning and fixing role, ensuring that the treatment plate will not be easily displaced during use, ensuring stable treatment of the exhaust gas. This design makes it more convenient and quick to replace the filter plate and adsorption plate, reducing maintenance costs and time.

[0015] The purifier includes a liquid holding part and a mixing and purification part. The purified liquid in the liquid holding part enters the mixing box under the action of a liquid pump, and after mixing with the exhaust gas, enters the purification area through the through holes on the mixing and purification part. The motor drives the push frame to rotate, so that the exhaust gas is purified in multiple purification areas in turn, extending the flow path and processing time of the exhaust gas in the purification device, so that the exhaust gas can be purified more thoroughly, thereby improving the quality of the exhaust gas.

[0016] In summary, the present invention has the advantages of significant filtering effect, easy installation and maintenance, and thorough purification effect, and can effectively treat anesthesia waste gas in the operating room and reduce harm to the environment and human body.

DETAILED DESCRIPTION

A plurality of guide plates 19 are staggered and arranged at equal distances in the filter box 1, and the number of the guide plates 19 is The purpose of setting the guide plate 19 is to guide the flow of exhaust gas in the filter box 1, so that the exhaust gas has an equidistant staggered flow path in the filter box 1, prolonging the residence time of the exhaust gas in the filter box 1, thereby increasing the contact time and contact area between the exhaust gas and the treatment plate 20, and improving the treatment effect of the exhaust gas. The side wall of the filter box 1 is symmetrically provided with an inlet pipe 13 and an outlet pipe 17. The inlet pipe 13 is installed with a mask 2 through a connecting hose 3. The side wall of each guide plate 19 is slidably connected with a treatment plate 20. The number of the treatment plates 20 is ; The processing plate 20 is provided with a plurality of filter plates and a plurality of adsorption plates in sequence on the path from the air inlet pipe 13 to the air outlet pipe 17. The filter plates can filter impurities in the exhaust gas. A part of the filter plates can adopt a high-efficiency air filter membrane (HEPA membrane) and another part can adopt a polytetrafluoroethylene (PTFE) membrane. The HEPA membrane has an extremely high filtration efficiency for tiny particles and can effectively remove suspended particulate matter in the anesthetic waste gas. It has high filtration accuracy and can capture nano-level particles. It has a good filtration effect on drug particles, bacteria, viruses, etc. that may exist in the anesthetic waste gas. At the same time, it has good corrosion resistance and can resist the erosion of chemical substances in the anesthetic waste gas to a certain extent. The PTFE membrane has excellent chemical stability and high temperature resistance, and can withstand the effects of high temperature and chemical substances that may exist in the anesthetic waste gas. Its surface is smooth, impurities are not easily adhered, and it is relatively easy to clean and maintain. In addition, the PTFE membrane has good air permeability, which can reduce airflow resistance while ensuring the filtering effect; the adsorption plate can use activated carbon fiber cloth or molecular sieve adsorbent. Activated carbon fiber cloth has a larger specific surface area and higher adsorption performance than traditional granular activated carbon, and can quickly adsorb organic gases and odorous substances in anesthetic waste gas. It has good softness and can be cut into different shapes and sizes as needed, which is convenient for installation on the adsorption plate. At the same time, the activated carbon fiber cloth has a large adsorption capacity and a relatively long service life; the molecular sieve has a regular pore structure and a specific pore size, and can selectively adsorb specific components in anesthetic waste gas. The molecular sieve can preferentially adsorb components such as carbon dioxide and volatile anesthetic drugs, thereby improving the pertinence and effect of waste gas treatment. In addition, the molecular sieve has a large adsorption capacity and good stability, and can be used in a wider temperature and humidity range.

[0021] Wedge strips 22 are installed on the side walls of both sides of each treatment plate 20, and a wedge-shaped groove 21 is opened on the guide plate 19.

The wedge strips 22 and the wedge-shaped grooves 21 facilitate the sliding installation and disassembly of the treatment plate 20 on the guide plate 19. At the same time, the wedge-shaped structure can play a certain positioning and fixing role, ensuring that the treatment plate 20 will not be easily displaced during use, and ensuring that the treatment plate 20 stably treats the exhaust gas.

The mixing box 8 provides a specific space for the waste gas and the purified liquid 25, ensuring that the two can efficiently contact and react under a certain pressure and flow rate, thereby more effectively removing harmful substances in the waste gas; the liquid pump 6 realizes the recycling of the purified liquid 25, so that the purified liquid 25 always maintains a high activity and concentration. The purified liquid 25 can continuously react with the waste gas during the continuous circulation process, thereby improving the purification effect of the waste gas. At the same time, the recycling of the purified liquid 25 also reduces costs.

[0023] An exhaust pipe 24 is connected to the outer wall of the purifier 12 . The exhaust pipe 24 is connected to the second air pump 5 through the third connecting pipe 7 . The second air pump 5 is installed on the outer wall of the filter box 1 .

[0024] The purifier 12 includes a liquid holding portion 1202, and the liquid holding portion 1202 is installed on the upper end surface of the filter box 1. The liquid holding portion 1202 contains a purification liquid 25, and the purification liquid 25 can be a sodium hydroxide solution, a sodium hypochlorite solution or a biological enzyme solution; the sodium hydroxide solution can react with the acidic anesthetic waste gas to neutralize and effectively remove the acidic components in the waste gas.

Assuming that the purification zone 26 corresponding to the mixing box 8 is the first purification zone, the purification zone 26 corresponding to the exhaust pipe 24 is the second purification zone.

[0025] Working principle: The anesthetic waste gas exhaled by the patient passes through the mask 2, enters the air inlet pipe 13 through the connecting hose 3, and then enters the filter box 1. In the filter box 1, multiple guide plates 19 guide the waste gas to flow in an equidistant staggered flow path. The treatment plate 20 is composed of multiple filter plates and multiple adsorption plates on the path from the air inlet pipe 13 to the air outlet pipe 17. The filter plate can filter impurities in the waste gas, and the adsorption plate can adsorb odors and harmful substances in the waste gas. In the process of the waste gas flowing in the filter box 1, the residence time is extended, thereby increasing the contact time and contact area with the treatment plate 20, thereby improving the waste gas treatment effect.

[0026] The waste gas that has been preliminarily treated passes through the outlet pipe 17 and the first connecting pipe 11 and enters the mixing box 8 under the action of the first air pump 10. At the same time, the liquid pump 6 pumps the purified liquid 25 in the liquid holding part 1202 of the purifier 12 into the liquid inlet pipe 16 of the mixing box 8 through the liquid pipe 17. The waste gas enters the mixing box 8 from the air inlet pipe 15 of the mixing box 8 and mixes with the purified liquid 25.

[0027] The motor 14 in the purifier 12 is started, driving the push frame 18 to rotate. The push cylinder 1801 and multiple push plates 1802 of the push frame 18 divide the mixing purification part 1201 into multiple purification areas 26. The mixed exhaust gas and purified liquid 25 enter the first purification area corresponding to the mixing box 8 through the through hole 23 on the mixing purification part 1201. As the motor 14 drives the push frame 18 to rotate counterclockwise, the exhaust gas and purified liquid pass through each purification area 26 in turn for further purification. Finally, the liquid in the purified material enters the liquid holding part 1202, and the purified gas floats up and then passes through the exhaust pipe 24 and the third connecting pipe 7, and is discharged under the action of the second air pump 5.
