It is difficult to completely remove various harmful substances in the anesthetic gas. The purification process fails to achieve a satisfactory removal effect, and the anesthetic gas needs to be mixed with oxygen or air before it can be used. Due to the change in the ambient air temperature, the temperature of the anesthetic gas is relatively low, and the patient is prone to cold reaction, which affects the patient's physical health and safety during surgery.

[0069] Gas filtration kit includes:

[0070] The hygroscopic and heat-generating silica gel frame 15 is installed inside the protective housing 2 3, and the hygroscopic and heat-generating silica gel frame 15 is a hollow pipe structure, and the surface of the hollow pipe is evenly spaced with openings;

[0071] The air-permeable mesh plate 16 is equidistantly installed inside the hygroscopic and heat-generating silica gel frame 15, and the side wall surface of the air-permeable mesh plate 16 penetrates the opening on the surface of the hollow tube of the hygroscopic and heat-generating silica gel frame 15.

A penetrating pipe is arranged inside the air-permeable mesh plate 16, and the pipe of the air-permeable mesh plate 16 is connected to the pipe inside the steering plate 18, and an L-shaped pipe connected to the inside of the connecting pipe 19 is arranged inside the steering plate 18;

[0072] A filter ring 17 is installed in the circular opening inside the air permeable mesh plate 16, and the filter ring 17 is set to a ring structure, and the filter ring 17 has built-in activated carbon particles;

[0073] A deflection plate 18 is mounted on the top of the filter ring 17, and the deflection plate 18 is located in the circular opening inside the air-permeable mesh plate 16, the top of the deflection plate 18 abuts against the bottom of the partition plate 20, and the partition plate 20 separates the internal chambers of the protective housing 23;

[0074] A connecting pipe 19 is installed at the bottom end of the filter ring 17, and the connecting pipe 19 is configured as a trumpet-shaped pipe structure, and the bottom end diameter of the connecting pipe 19 is consistent with the diameter of the steering plate 18;

[0075] The partition plate 20 is installed on the outer wall of the connecting pipe 19, and the interior of the partition plate 20 is penetrated by the moisture-absorbing and heat-generating silica gel frame 15, and the surface of the partition plate 20 is against the inner wall of the protective shell 23.

[0076] In conjunction with the accompanying drawings Figure 1-Figure 10As shown, the hygroscopic and heat-generating silica gel frame 15 is located in the protective shell 23 to support the internal overall structure. At the same time, with the installation and installation of the partition plate 20, the internal space of the protective shell 23 is further graded. The connecting pipe 19 installed inside the partition plate 20 and connected to the filter ring 17 realizes the gas flow between each level. After the gas passes through the connecting pipe 19 and enters the filter ring 17, the impurities and other substances in the gas are intercepted and adsorbed by the activated carbon particles to maintain the cleanliness of the gas. The hygroscopic and heat-generating silica gel frame 15 is composed of silica gel and a physical hygroscopic and heat-generating agent to form a tubular structure. Through the chemical reaction of the substance absorbing and releasing moisture, the hygroscopic and heat-generating silica gel frame 15 produces a certain exothermic effect. The main principle is that while absorbing moisture, the absorbed moisture reacts with the chemical substances on the surface of the adsorbent to release heat. The hygroscopic and heat-generating silica gel frame 1 5. The silicone material is used. Since there are a large number of fine pores in the silicone, it can efficiently absorb moisture. The adsorption capacity of the silicone is not affected by temperature, humidity and pressure, so it is widely used. It can provide a heating operation for the gas during use. After the high-temperature gas passes through the one-way blocking rod 22 of the gas mixing tube 21, the low-temperature anesthetic gas in winter is temperature-adjusted during the mixing period to prevent the low-temperature anesthetic gas from entering the breathing mask of the clinical patient. When the gas passes through the one-way blocking rod 22, the memory metal spring at the connection between the one-way blocking rod 22 and the gas mixing tube 21 drops according to the temperature change. When a high temperature condition occurs, the one-way blocking rod 22 and the pipeline position of the gas mixing tube 21 are directly closed to start the contact switch 23, alerting the staff that the temperature in the anesthetic gas is overloaded, which is convenient for medical staff to handle.

[0077] Working principle: When using the clinical anesthetic gas purification device for anesthesia department, firstly connect the inhaled anesthetic gas pipeline with the bottom end of the anesthetic gas docking tube 4, connect the oxygen or air pipeline of the mixed anesthetic gas with the mixed gas docking tube 14, and move the independent blocking block 24 to the side of the top of the discharge pipe 12, and then connect the discharge pipe 12 with the gas mixing tube 21, and connect the other end of the gas mixing tube 21 with the clinical patient's breathing mask. When in use, the radiation disinfection lamp tube 8 is turned on in advance and irradiated and disinfected by the visible light lamp tube located in the protective shell 1. As the anesthetic gas enters the guide tube 5, it is processed by the catalytic activated carbon filter 6. The filter screen stacked inside the catalytic activated carbon filter 6 and the HEPA filter plate 11 uses a mesh structure made of high-efficiency activated carbon fiber material and chemical filter material to convert toxic components in common anesthetic waste gas, such as halothane, enflurane, etc. into harmless substances. With the concentric circles in the flow channel, the structure in the device is fully flowed and affected by the radiation disinfection lamp. After the tube 8 is irradiated by the light source, it enters the exhaust pipe 12. The opening at the top of the exhaust pipe 12 is connected to the gas monitoring equipment as needed to facilitate detection and processing. The hygroscopic and heat-generating silicone frame 15 installed inside the protective shell 23 provides an installation position for the breathable mesh plate 16 and the partition plate 20, and distributes the internal space into multiple spaces. As the connecting pipe 19 is connected, the gas is sent into the filter ring 17, filtered by the activated carbon, and then passes through the internal pipeline of the breathable mesh plate 16 to enter the turning plate 18 and flow to the upper-level connecting pipe 19. It is filtered and processed in turn and passes through the one-way blocking rod 22 inside the gas mixing tube 21 to mix with the anesthetic gas in a moderate contact and flow to the patient's breathing mask. The physical hygroscopic and heat-generating agent of the hygroscopic and heat-generating silicone frame 15 located inside the protective shell 23 absorbs moisture and releases water through the chemical reaction, so that the hygroscopic and heat-generating silicone frame 15 produces a certain exothermic effect to heat up the internal temperature, providing a heating operation for the low-temperature gas in winter to avoid affecting the working effect of the anesthetic gas.

[0078] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
