Description

Technical Field

[0001] This utility model relates to the field of nasal oxygen tube technology, specifically a filter-type nasal oxygen tube with anti-clogging and CO2 monitoring function. Background Technology

[0002] A nasal oxygen tube with CO2 monitoring is a medical device used in respiratory, anesthesia, and emergency care. It mainly consists of a nasal oxygen tube and a carbon dioxide monitoring sensor. One end delivers medical oxygen to the patient's nasal cavity, while the other end connects to the oxygen supply device to monitor the carbon dioxide content of the exhaust gas in real time. This type of nasal oxygen tube is usually designed for single use to avoid cross-infection, and it is soft and comfortable, reducing patient discomfort.

[0003] Existing nasal oxygen cannulas are widely used. During use, oxygen is usually humidified by passing it through water. However, if the air flow rate is high during this process, water may enter the nasal oxygen cannulas along with the oxygen, causing blockage. Water may even be sprayed into the nasal cavity, which is quite dangerous. Therefore, to address the above issues, a filter-type nasal oxygen cannulas with anti-clogging and CO2 monitoring function is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a filter nasal cannula with anti-clogging and CO2 monitoring function to solve the problem mentioned in the background art that the existing devices cannot prevent water clogging.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A filter-type nasal oxygen cannula with anti-clogging and CO2 monitoring function includes a nasal tube and a first connecting tube fixedly connected to the bottom end of the nasal tube. A carbon dioxide monitor is provided below the first connecting tube. Fixers are symmetrically installed at the upper and lower ends of the carbon dioxide monitor. A fixing cylinder is installed at the end of each fixing device away from the carbon dioxide monitor. A storage cylinder is fixedly connected inside the lower fixing cylinder. An absorbent block is fixedly connected to the inner side of the storage cylinder. Multiple through holes are opened in the inner wall of the storage cylinder. Multiple inclined connecting rods are fixedly connected to the inner side of the inner wall of the storage cylinder. A through groove is opened at the bottom end of each connecting rod. A connecting block is fixedly connected to the end of each connecting rod away from the storage cylinder. A second connecting tube is installed at the bottom end of the lower fixing cylinder. The upper and lower fixing cylinders are fixedly connected to the first connecting tube and the second connecting tube respectively through connectors.

[0007] Preferably, a heating wire that penetrates the fixed cylinder is installed inside the fixed cylinder located at the top, and a heater that is fixedly connected to the outside of the fixed cylinder is installed on one side of the heating wire.

[0008] Preferably, the fixture includes threaded joints that are fixedly connected to two fixed cylinders respectively, and the outer side of the threaded joints is threadedly connected to threaded caps that are fixedly connected to both ends of the carbon dioxide monitor.

[0009] Preferably, the connector includes connecting cylinders that are fixedly connected to two fixed cylinders respectively, the outer surface of the connecting cylinders having symmetrical connecting grooves, and the outer side of the connecting cylinders having symmetrical rubber rings.

[0010] Preferably, the rubber rings are horizontally aligned with the connecting grooves, the first connecting pipe and the second connecting pipe are both sleeved on the outside of the connecting cylinder, and a plurality of rubber rings are respectively sleeved on the outside of the first connecting pipe and the second connecting pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting up a storage tube, a water-absorbing block, a through hole, a connecting rod, a through groove, and a connecting block, if water enters the second connecting pipe along with oxygen, the connecting block can intercept the water. As oxygen continuously enters the fixed tube, the water impacted by the oxygen can enter the through hole through the through groove on the connecting rod and be absorbed by the water-absorbing block in the storage tube. This design can filter and absorb the water entering the second connecting pipe, effectively preventing water from clogging the second connecting pipe and preventing water from being discharged through the nasal tube.

The upper and lower fixed cylinders 5 are fixedly connected to the first connecting pipe 2 and the second connecting pipe 14 respectively through connectors 15. Through the set storage cylinder 6, water absorption block 7, through hole 8, connecting rod 9, through groove 10 and connecting block 11, if water enters the second connecting pipe 14 with oxygen, the connecting block 11 can intercept the water. As oxygen continuously enters the fixed cylinder 5, the water is impacted by oxygen and can enter the through hole 8 through the through groove 10 on the connecting rod 9, and is absorbed by the water absorption block 7 in the storage cylinder 6. This design can filter and absorb the water entering the second connecting pipe 14, effectively preventing water from clogging the second connecting pipe 14 and preventing water from being discharged through the nasal tube 1.

[0028] A heating wire 12 is installed inside the upper fixed cylinder 5, which passes through the fixed cylinder 5. A heater 13 is installed on one side of the heating wire 12 and fixedly connected to the outside of the fixed cylinder 5. Through the heating wire 12 and the heater 13, the oxygen can be heated, so that the oxygen temperature is slightly increased, and the patient's nasal cavity is avoided from being too cold.

[0029] The fixture 4 includes threaded connectors 41 that are fixedly connected to two fixed cylinders 5 respectively. Threaded caps 42 that are fixedly connected to both ends of the carbon dioxide monitor 3 are threadedly connected to the outside of the threaded connectors 41. The connector 15 includes connecting cylinders 151 that are fixedly connected to the two fixed cylinders 5 respectively. Connecting grooves 152 are symmetrically opened on the outer surface of the connecting cylinders 151. Rubber rings 153 are symmetrically arranged on the outside of the connecting cylinders 151. The rubber rings 153 are horizontally aligned with the connecting grooves 152. The first connecting pipe 2 and the second connecting pipe 14 are both sleeved on the outside of the connecting cylinder 151. Multiple rubber rings 153 are respectively sleeved on the outside of the first connecting pipe 2 and the second connecting pipe 14. The fixture 4, threaded connectors 41, threaded caps 42, fixed cylinders 5, second connecting pipes 14, connector 15, connecting cylinders 151, connecting grooves 152, and rubber rings 153 make the installation of the device convenient and facilitate the replacement of the first connecting pipe 2 and the second connecting pipe 14.

[0030] Workflow: First, install the various components of the device. Use the retainer 4 to connect the carbon dioxide monitor 3 to the two fixed cylinders 5 respectively. Screw the threaded cap 42 on the carbon dioxide monitor 3 onto the outside of the two threaded joints 41. Then, use the connector 15 to connect the first connecting pipe 2 and the second connecting pipe 14 to the two fixed cylinders 5 respectively. Place the rubber ring 153 on the outside of the first connecting pipe 2 and the second connecting pipe 14 respectively. Place the first connecting pipe 2 and the second connecting pipe 14 on the outside of the connecting cylinder 151. Then move the rubber ring 153 until the rubber ring 153 is horizontally aligned with the connecting groove 152 and the inside of the rubber ring 153 is tightly fitted with the outside of the first connecting pipe 2 and the second connecting pipe 14. The assembly of the device is now complete.

When using the device, the nasal tube 1 is put on the patient's face and the oxygen supply device is turned on. The oxygen is discharged through the second connecting pipe 14, the first connecting pipe 2 and the nasal tube 1. If water follows the oxygen into the second connecting pipe 14, the connecting block 11 can intercept the water. As oxygen continuously enters the fixed cylinder 5, the water impacted by the oxygen can enter the through hole 8 through the through groove 10 on the connecting rod 9 and be absorbed by the water absorption block 7 in the collection cylinder 6. This design can filter and absorb the water entering the second connecting pipe 14, effectively preventing water from clogging the second connecting pipe 14 and preventing water from being discharged through the nasal tube 1. The design of the fixer 4 and connector 15 makes the installation of the device convenient and facilitates the replacement of the first connecting pipe 2 and the second connecting pipe 14.
