Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a breathing machine filtering device. Background Art

[0002] A ventilator filter is a device used to filter and purify the air delivered to the patient in the ventilator system. Simply put, a ventilator filter is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the patient's life.

[0003] However, most of the current ventilator filters are made of medical foam or dust removal filter media. During use, some tiny fibers are prone to fall off. If the tiny fibers are inhaled by the patient, they may irritate the respiratory tract, causing discomfort or even allergic reactions, especially for those patients who are allergic to fibers or have respiratory sensitivity, which may aggravate the symptoms.

It can adhere to the tiny fibers dropped from the filter medium filled inside, greatly reducing the probability of being inhaled into the nose by the user, with better safety performance and stronger practicality.

[0005] Although the above patent is able to adhere to the tiny fibers dropped from the internally filled filter medium, greatly reducing the chance of them being inhaled into the user's nose, with better safety performance and stronger practicality; however, the device does not have a heating structure. When the device is used for a long time, water vapor condensation may occur inside the device, resulting in a decrease in filtration efficiency or an increase in resistance, shortening the service life of the device.

[0006] Therefore, it is necessary to propose a breathing machine filtering device to solve the above problems. Utility Model Content

[0012] As a further solution of the utility model, the disassembly and assembly mechanism includes a threaded ring opened on the top of the vessel surface, the surface of the threaded ring is threadedly connected with a screw cap, the top of the screw cap is opened at the bottom of the connecting pipe, and the screw cap serves to facilitate the disassembly and assembly of the filtering mechanism.

[0013] As a further solution of the utility model, the constant temperature mechanism includes an insulation layer fixedly connected to the bottom of the vessel surface, the heating belt is electrically connected to the inside of the insulation layer through a power cord, and one side of the insulation layer is electrically connected to a controller through a power cord.

[0016] (III) Beneficial effects

[0017] The utility model provides a breathing machine filter device, which has the following beneficial effects:

[0018] 1. The ventilator filter device is provided with a filtering mechanism and a disassembly mechanism. When air enters the interior of the vessel and passes through the filtering mechanism, the fiber glass uses its high density and fine fiber structure to capture tiny particles. Then the nanofiber membrane uses its slender structure to retain tiny particles for a second time. Then, the remaining tiny fibers are captured on the surface through the pore size, surface tension and electrostatic adsorption of the protective membrane. Then, activated carbon is used to adsorb gaseous pollutants and odors in the air, which is beneficial to filtering tiny fibers and preventing tiny fibers from being inhaled by patients, irritating the respiratory tract, causing discomfort or even allergic reactions. In addition, the threaded ring and the screw cap are threaded structures, which are convenient for later disassembly and replacement of the filtering mechanism.

[0019] 2. The ventilator filter device achieves antibacterial effect by setting up antibacterial plastic and silver ion coating. Antibacterial agents are added to the antibacterial plastic. These antibacterial agents can kill or inhibit the growth of bacteria, fungi and other microorganisms, thereby reducing the deposition and reproduction of bacteria on the surface of the vessel. The silver ion coating has strong antibacterial properties and can kill a wide range of bacteria, fungi and viruses, ensuring the cleanliness of the vessel and reducing the spread of bacteria and other microorganisms.

[0020] 3. The ventilator filter device is equipped with a constant temperature mechanism and a heating belt. When the power is turned on, the target temperature of the heating belt is set by the controller, and the heating belt is started. The heating belt in the insulation layer heats the inside of the vessel until it is heated to the set target temperature, thereby avoiding the problem of water vapor condensation inside the device, which leads to a decrease in the filtration efficiency of the device or an increase in the resistance, and prolongs the service life of the device. The insulation layer has a certain thermal insulation performance, which can avoid the rapid loss of heat generated by the heating belt. BRIEF DESCRIPTION OF THE DRAWINGS
