Description

Technical Field

[0001] This utility model relates to the field of breathing circuit filters, and more specifically, to a breathing circuit filter. Background Technology

[0002] A breathing circuit filter is a filter that can filter bacteria and pathogens in the air in a ventilator circuit. Existing breathing tubes have poor protection at the connection points, which are prone to loosening during use and can easily cause the breathing tube to fall off.

[0003] Chinese patent application number CN202321851564.7 discloses a breathing circuit filter. This design involves rotating a threaded rod clockwise downwards. The upper cone of the latch engages with the conical groove inside the lower end of the threaded rod, causing the latch to tighten inwards, thus securing the breathing tube. The user can then place the breathing tube from the filter end over the breathing tube from the mask end and adjust the latch to achieve a secondary fixation of the breathing tube. This prevents loosening due to head movement, ensuring the patient's health. However, the breathing circuit may contain moisture, hindering gas return and potentially leading to water accumulation and bacterial growth within the tubing.

[0004] Therefore, a breathing circuit filter is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a breathing circuit filter. The filter is detachably connected to the output end of a pipe. The exhaust port of the threaded pipe facilitates the discharge of incoming gas onto the spiral blades, allowing the gas to travel on the blades. The spiral blades are made of absorbent cotton, which adsorbs moisture in the gas. The gas then travels into the filter cartridge, where it kills bacteria. The inner and outer walls of the filter cartridge are coated with a bactericide, which further purifies the gas during flow. A non-slip sleeve facilitates user grip and connection to the threaded pipe. Activated carbon rings further adsorb the gas.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A breathing circuit filter includes a tubing with a filter detachably connected to its output end. The filter includes a threaded tube with a filter cartridge inserted inside. A detachable threaded connector is located inside the filter cartridge. A helical blade is fixedly connected to the outer end of the threaded connector, and the helical blade fits against the inner wall of the filter cartridge. A plug is fixedly connected to the outer end of the threaded connector, located at the front end of the helical blade. The plug is located at the input end of the threaded tube and is adapted to the threaded tube. The plug and the threaded tube are magnetically attracted. An anti-slip sleeve is threadedly connected to the outer end of the threaded tube. Multiple activated carbon rings arranged at equal intervals are fixedly connected to the inner wall of the anti-slip sleeve, and the activated carbon rings are located on the outer wall of the threaded tube.

[0008] The detachable connection between the pipeline output end and the filter facilitates filter installation, replacement, and maintenance. The filter cartridge is inserted into the threaded pipe, allowing for easy installation, removal, replacement, and cleaning. The vent hole in the threaded pipe directs incoming gas onto the spiral blades, which absorb moisture. The gas then travels through the absorbent cotton material, which kills bacteria within the gas. The filter cartridge, coated with a bactericide, purifies the gas as it flows. A non-slip sleeve facilitates gripping and connection to the threaded pipe. Activated carbon rings further adsorb gases.

[0009] Preferably, the outer end of the screw connector has multiple vent holes arranged at equal intervals, and the vent holes are adapted to the helical blades.

[0010] Preferably, the outer wall of the filter cartridge has multiple adsorption holes arranged at equal intervals, and the adsorption holes are adapted to the spiral blades.

[0011] Preferably, the threaded tube has multiple slots arranged at equal intervals inside.

[0012] Preferably, the outer wall of the filter cartridge is fixedly connected with a plurality of inserts arranged at equal intervals, and the inserts are adapted to the slots.

[0013] Preferably, the threaded connector is threadedly connected to the air intake pipe of the breathing circuit.

[0014] Preferably, the anti-slip sleeve is threadedly connected to the air outlet pipe of the breathing circuit.

[0015] In summary, this utility model has the following beneficial effects:

[0016] (1) The exhaust port of the screw pipe in this scheme facilitates the discharge of the gas to the spiral blade, so that the gas can travel on the spiral blade. The spiral blade is made of absorbent cotton, which can adsorb water vapor in the gas.

[0017] (2) This solution uses a filter cartridge with a bactericide coating on the outer wall to kill bacteria in the gas during gas flow and to purify the gas. Attached Figure Description

[0028] The detachable connection between the output end of pipe 1 and filter 2 facilitates the installation, replacement, and maintenance of filter 2. The threaded pipe 201 is internally connected to filter cartridge 205, enabling easy installation, removal, replacement, and cleaning of filter cartridge 205. The vent hole of the threaded pipe 203 guides the incoming gas to the spiral blades 204, allowing the gas to travel on the spiral blades 204. The spiral blades 204 are made of absorbent cotton, which adsorbs moisture in the gas. The gas then travels into filter cartridge 205, where it kills bacteria. Filter cartridge 205, with its inner and outer walls coated with a bactericide, purifies the gas during flow. The anti-slip sleeve 206 facilitates user gripping and connection to the threaded pipe 201. The activated carbon ring 207 further adsorbs the gas.

[0029] The outer end of the screw connector 203 has multiple vent holes arranged at equal intervals, and the vent holes are adapted to the helical blade 204.

[0030] The outer wall of the filter cartridge 205 has multiple adsorption holes arranged at equal intervals, and the adsorption holes are adapted to the spiral blades 204.

[0031] The adsorption holes facilitate gas flow without affecting the sterilization of bacteria in the gas by the filter cartridge 205.

[0032] The threaded tube 201 has multiple slots arranged at equal intervals inside.

[0033] The outer wall of the filter cartridge 205 is fixedly connected with multiple inserts arranged at equal intervals, and the inserts are adapted to the slots;

[0034] The insert and slot make it easy to assemble and disassemble the filter cartridge 205 and the threaded tube 201, allowing users to easily replace or clean the filter cartridge 205 later.

[0035] The threaded connector 203 is threadedly connected to the air intake pipe of the breathing circuit.

[0036] The screw connector 203 is connected to the breathing circuit air intake pipe, which allows the user to conduct the exhaled air into the screw connector 203 for subsequent purification.

[0037] The anti-slip sleeve 206 is threadedly connected to the air outlet pipe of the breathing circuit.

[0038] The purified gas is delivered to the breathing circuit through the anti-slip sleeve 206 and the air outlet pipe of the breathing circuit, which facilitates gas recovery and prevents gas leakage.

[0039] The specific implementation process is as follows: First, the gas enters the screw-in pipe 203 of the filter 2 through the air intake pipe of the breathing circuit, which is threadedly connected to the screw-in pipe 203. After reaching the screw-in pipe 203, the gas is discharged to the spiral blades 204 through the equidistantly arranged exhaust holes at its outer end. The water-absorbing cotton material of the spiral blades 204 can absorb the water vapor in the gas. Then, the gas continues to flow along the spiral blades 204 into the filter cartridge 205. Since the inner and outer walls of the filter cartridge 205 are coated with bactericide, bacteria in the gas can be killed when the gas passes through, thus purifying the gas. Finally, the purified gas is discharged from the air outlet pipe of the breathing circuit, which is threadedly connected to the anti-slip sleeve 206. During the process, the activated carbon ring 207 can further adsorb the gas.
