[0001] The utility model relates to anesthesia breathing filtering technology in the separation field, in particular to an anti-falling convenient breathing filter for anesthesia department. Background Art
[0002] Anesthesiology is an important medical department. When performing orthopedic surgery, the anesthesiologist needs to use anesthetic drugs to anesthetize the patient before the surgery can be performed painlessly. When facing inhaled anesthesia, since the anesthetic drugs need to enter the patient's body through the respiratory tract, dust and bacteria may be inhaled simultaneously in the process (the human body's immunity is very low during anesthesia, which may cause certain dangers), so a respiratory filter is needed to filter the inhaled gas.
[0003] In the prior art, a Chinese patent with publication number CN115944973A discloses an intelligently controlled breathing filter for anesthesia, comprising a lower breathing sleeve and a filtering device, wherein an upper breathing sleeve is arranged above the lower breathing sleeve, and opposite ends of the lower breathing sleeve and the upper breathing sleeve are connected with a butt-jointed pipe, and the lower breathing sleeve and the upper breathing sleeve are both arranged in a conical shape. Through the mutual cooperation between the lower breathing sleeve, the upper breathing sleeve, the annular iron plate, the annular magnet, the threaded hole, the threaded rod, the activated carbon plate and the through groove, the upper breathing sleeve can be rotated to open the upper end of the lower breathing sleeve, and then the filtering device can be lifted up to remove the annular magnet from being adsorbed on the annular iron plate, and then the threaded rod is rotated to move upward in the threaded hole, driving the filter cotton to move upward and overlap with four overlapping blocks, so as to realize lifting the connecting ring upward, and when it moves to a suitable position, a number of activated carbon plates are taken out from top to bottom in sequence to complete the replacement, so that the disassembly and assembly are faster and more convenient.
[0004] Combining the above materials, it can be known that in the prior art, filter cotton generally achieves the purpose of filtering, but in actual use, the filter needs to be connected to the pipeline to connect to the anesthesia equipment. The pipeline of the above device is only connected in a nested manner, and there is no effective fixing measure. During use, it may fall off under the impact force of the gas. Utility Model Content

[0028] When using the device, first loosen the bolts of the fixing buckle 201 to remove the front cover 2, then install the filter cotton 6 (including the dust filter element 601 and the bacteria filter element 602) into the outer shell 1 through the installation slide 8, and then close the front cover 2. Then, the connecting pipe 9 of the anesthesia device is connected to the air inlet pipe 5 and the air outlet pipe 4, and the sealing effect is achieved by using the sealing ring 7 outside the air inlet pipe 5 and the air outlet pipe 4. During anesthesia, the gas enters the inner part of the outer shell 1, and the internal filter cotton 6 is used to filter impurities such as dust and bacteria.
[0029] Example 2: Please refer to Figure 3-Figure 4 In order to achieve the purpose of fixing and preventing the air outlet pipe 4 and the air inlet pipe 5 from falling off, the present embodiment provides the following technical solutions, which specifically disclose: a connecting pipe 9 for connecting to an anesthesia device is nested and installed outside the air outlet pipe 4 and the air inlet pipe 5, and limit blocks 10 for clamping and fixing the connecting pipe 9 are arranged on the upper and lower sides of the outer shell 1, a connecting rod 11 is rotatably installed between the limit block 10 and the outer surface of the outer shell 1, and a return spring 13 is installed between the outer surface of the connecting rod 11 and the outer surface of the outer shell 1, the limit block 10 is arranged to be an arc structure that fits the connecting pipe 9, and a rough extrusion pad 12 is fixedly installed on the inner surface of the limit block 10.
[0030] After installing the connecting tube 9, the limit block 10 is loosened. At this time, the connecting rod 11 is driven to rotate under the elastic pulling action of the reset spring 13, so that the connecting rod 11 pushes the limit block 10 at its top to move to a position that fits the outer surface of the connecting tube 9. At this time, under the elastic pulling action, the extrusion pad 12 on the inner wall of the limit block 10 is squeezed and rubbed with the connecting tube 9, thereby achieving the purpose of limiting and fixing the connecting tube 9 and avoiding falling off during use.
