Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a gas filtration device. Background Technology

[0002] Gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, pharmaceuticals, food, mining, power, and urban water supply. Particularly in the medical field, when anesthesia is required for surgical procedures, the use of an anesthesia machine for general anesthesia is a commonly used and safe technique. Inhalation anesthesia machines deliver gaseous anesthetics via respiration, achieving general anesthesia. Therefore, a filter device needs to be installed on the air intake line of the anesthesia machine to filter the gas entering the machine, ensuring the number of gas particles meets the required standards and guarantees surgical safety.

[0003] Existing gas filtration devices are all cylindrical in shape, which can easily fall off during handling by medical staff, thus increasing the risk of surgery. Therefore, we need to design a gas filtration device that is easy to handle and not prone to falling off. Utility Model Content

[0004] The purpose of this utility model is to provide a gas filtration device with a gripper on the outer surface of the cylinder and an anti-slip part on the gripper to ensure that the gas filtration device will not fall during handling, thereby improving the safety of the gas filtration device.

Filter paper is provided on the outside of the filter cotton at the outlet pipe connector. A gripper is provided on the outside of the cylinder. The gripper includes two planes symmetrically arranged along the center of the cylinder, and each plane is provided with an anti-slip part.

[0006] Preferably, the anti-slip part includes a plurality of anti-slip strips, which are vertically arranged on the plane and distributed at equal intervals.

[0007] Preferably, the anti-slip part is a mesh structure formed by several anti-slip strips arranged in a cross pattern.

[0008] Specifically, the anti-slip part is integrally formed with the plane.

[0009] Furthermore, the end face of the cylinder connected to the air inlet pipe connector is provided with an end-tidal carbon dioxide detection port communicating with it, and the end-tidal carbon dioxide detection port is provided with a sealing plug.

[0010] Furthermore, the cylinder is also provided with a sealing plug placement column, which is located on the same end face as the end-tidal carbon dioxide detection port.

[0011] Furthermore, the adsorption medium is calcium lime or sodium lime.

[0012] Specifically, both the air inlet pipe connector and the air outlet pipe connector are double-layer sleeve structures, each including an inner pipe and an outer pipe, and the inner pipe diameter of the air inlet pipe connector is larger than the inner pipe diameter of the air outlet pipe connector.

[0015] 1. The gas filtration device of this utility model has a flat gripper on the outer surface of the original cylindrical body, and vertical strip anti-slip part or mesh anti-slip part is provided on the gripper to effectively prevent the gas filtration device from falling during the handling process and improve the safety of the gas filtration device.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In one specific embodiment of this utility model, such as Figure 1-2 As shown, a gas filtration device is connected to a surgical anesthesia machine, specifically including a cylinder 1, an inlet pipe connector 2, and an outlet pipe connector 3. The inlet pipe connector 2 and the outlet pipe connector 3 are respectively connected to both ends of the cylinder 1. Both the inlet pipe connector 2 and the outlet pipe connector 3 are double-layer sleeve structures, each including an inner tube and an outer tube. The diameter of the inner tube of the inlet pipe connector 2 is larger than the diameter of the inner tube of the outlet pipe connector 3. Specifically, the inner tube diameter of the inlet pipe connector 2 is 2.2 cm, and the inner tube diameter of the outlet pipe connector 3 is 1.7 cm.

[0025] The cylinder 1 is filled with an adsorption medium 6, which is calcium lime or sodium lime. The calcium lime or sodium lime effectively adsorbs impurities in the gas. Filter cotton 7 is installed at both ends of the cylinder 1 between the inlet pipe connector 2 and the outlet pipe connector 3. The filter cotton 7 is positioned between the adsorption medium 6 and the inlet pipe connector 2 and the outlet pipe connector 3. Filter paper 8 is installed on the outside of the filter cotton 7 at the outlet pipe connector 3. This ensures that after the gas enters through the inlet pipe connector 2, it undergoes initial filtration by the filter cotton, then adsorption filtration by the calcium lime or sodium lime adsorption medium, further filtration by the filter cotton, and finally filtration and moisture absorption by the humidifying paper before being discharged through the outlet pipe connector. The gas undergoes multiple filtrations to ensure its quality.

[0026] The outer side of the cylinder 1 is provided with a gripper, which includes two planes 11 symmetrically arranged along the center of the cylinder 1. Each plane 11 is provided with an anti-slip part 12. The anti-slip part 12 is integrally formed with the plane 11 and includes a plurality of anti-slip strips. The plurality of anti-slip strips are vertically arranged on the plane 11 and evenly distributed, effectively preventing the gas filter device from falling during handling and improving the safety of the gas filter device.

[0027] The end face of the cylinder 1 connected to the air inlet pipe connector 2 is provided with an end-tidal carbon dioxide detection port 4 that communicates with it. The end-tidal carbon dioxide detection port 4 is used to connect to the end-tidal carbon dioxide connection line to monitor the end-tidal carbon dioxide partial pressure value.

[0028] The end-tidal carbon dioxide detection port 4 is equipped with a sealing plug for sealing the end-tidal carbon dioxide detection port 4. When it is necessary to connect the end-tidal carbon dioxide connection line, the sealing plug is removed before connection. When it is not necessary to connect the end-tidal carbon dioxide connection line, the sealing plug is used to seal the end-tidal carbon dioxide detection port.

[0029] The cylinder 1 is also provided with a sealing plug placement column 5, which is located on the same end face as the end-tidal carbon dioxide detection port and is used to place the removed sealing plug.

[0030] Specifically, in another embodiment of this utility model, such as Figure 3 As shown, the anti-slip part 12 is a mesh structure formed by several anti-slip strips arranged in a cross pattern.

[0031] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
