Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a scraping device for convenient cleaning of the wall of endotracheal tubes. Background Technology

[0002] Endotracheal intubation is a tube inserted through the mouth or nose and through the glottis into the trachea or bronchus when the patient is under general anesthesia, in a coma, or with upper airway obstruction. It provides optimal conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure to ensure surgical safety and rescue patients with respiratory dysfunction.

[0003] After prolonged use, existing endotracheal tubes often develop sputum crusts on their inner walls. Due to the narrow internal space, cleaning the inner walls is inconvenient, affecting airflow and potentially causing breathing difficulties for patients. Therefore, we have introduced a new scraping device that facilitates cleaning the walls of endotracheal tubes. Utility Model Content

[0004] The main purpose of this invention is to provide a scraping device for cleaning the wall of an endotracheal tube, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A scraping device for convenient cleaning of the endotracheal tube wall includes a connecting rod and a connecting block. The upper end of the connecting rod has a threaded groove, and the outer surface of the connecting rod has a scale strip. The lower end of the connecting rod is fixedly connected to a handle, and the outer surface of the handle is provided with an anti-slip sleeve. The lower end of the handle is fixedly connected to a limiting piece. The lower middle part of the connecting block is fixedly connected to a threaded block. The connecting block has several movable grooves inside, and springs are fixedly connected to the inner walls of the several movable grooves. The ends of the several springs away from the inner walls of the movable grooves are fixedly connected to a limiting block. The ends of the several limiting blocks away from the springs are fixedly connected to scrapers. The upper part of the outer surface of the several scrapers is provided with an arc edge.

[0007] Preferably, the threaded block is threadedly connected to the threaded groove.

[0008] Preferably, the outer surfaces of the plurality of limiting blocks are respectively movably connected to the inner walls of the plurality of movable grooves.

[0009] Preferably, several scrapers are interleaved and movably connected to several movable slots.

[0010] Preferably, the plurality of the scrapers are arranged in a ring array.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By holding the handle, place the connecting block inside the endotracheal tube opening. Push the connecting block into the endotracheal tube using the connecting rod. When encountering obstructions such as phlegm or crusts inside the endotracheal tube, the arc edge on the scraper allows the scraper to pass smoothly through the obstruction. The scraper then compresses the spring by passing through the limiting block. After the connecting block is inserted to a certain depth, several scrapers are reset by the spring force, causing the scrapers to pop out and fit tightly against the inner wall of the endotracheal tube at the end away from the limiting block. Then, pull the connecting rod back using the handle. The connecting rod, along with the connecting block, pulls back, allowing several scrapers to scrape away the phlegm or crusts from the inner wall of the endotracheal tube. Repeat the scraping operation several times to easily remove and clean the phlegm or crusts from the inner wall of the endotracheal tube, ensuring unobstructed passage inside the endotracheal tube.

[0013] 2. Thread the threaded block below the connecting block into the threaded groove above the connecting rod to facilitate the connection between the connecting block and the connecting rod. A scale strip is set on the outer surface of the connecting rod to facilitate observation of the insertion depth. An anti-slip sleeve is set on the outer surface of the handle to improve the anti-slip effect and prevent slippage during the pulling process. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A scraping device for convenient cleaning of the endotracheal tube wall includes a connecting rod 1 and a connecting block 2. The upper end of the connecting rod 1 has a threaded groove 3, and the outer surface of the connecting rod 1 has a scale strip 4. The lower end of the connecting rod 1 is fixedly connected to a handle 5, and the outer surface of the handle 5 is provided with an anti-slip sleeve 6. The lower end of the handle 5 is fixedly connected to a limiting piece 7. The lower middle part of the connecting block 2 is fixedly connected to a threaded block 8. The connecting block 2 has a plurality of movable grooves 9 inside. The inner wall of each movable groove 9 is fixedly connected to a spring 10. The end of each spring 10 away from the inner wall of the movable groove 9 is fixedly connected to a limiting block 11. The end of each limiting block 11 away from the spring 10 is fixedly connected to a scraper 12. The upper part of the outer surface of each scraper 12 is provided with an arc edge 13.

[0024] In this embodiment, the threaded block 8 is threadedly connected to the threaded groove 3, which facilitates the connection between the connecting block 2 and the connecting rod 1. The outer surfaces of several limiting blocks 11 are respectively movably connected to the inner walls of several movable grooves 9.

[0025] In this embodiment, several scrapers 12 are interlocked and movably connected to several movable slots 9. The scrapers 12 are arranged in a ring array. The scrapers 12 can scrape off the sputum crusts on the inner wall of the endotracheal tube. The scraping operation can be repeated several times to facilitate the scraping and cleaning of the sputum crusts on the inner wall of the endotracheal tube, so that the inside of the endotracheal tube can be unobstructed.

[0026] It should be noted that this utility model is a scraping device for conveniently cleaning the wall of an endotracheal tube. During use, the internal diameter of the endotracheal tube is generally 6.5-8.0 mm. The diameter of the connecting block 2 is smaller than the internal diameter of the endotracheal tube. The threaded block 8 below the connecting block 2 is threaded into the threaded groove 3 above the connecting rod 1, facilitating the connection between the connecting block 2 and the connecting rod 1. A scale strip 4 is provided on the outer surface of the connecting rod 1 for easy observation of the insertion depth. An anti-slip sleeve 6 is provided on the outer surface of the handle 5 to improve the anti-slip effect and prevent slippage during pull-out. In specific operation, by holding the handle 5, the connecting block 2 is placed inside the endotracheal tube opening, and the connecting rod 1 is used to push the connecting block 2 into the endotracheal tube. When encountering... When obstructions such as sputum crusts are found inside the endotracheal tube, the arc edge 13 on the scraper 12 allows the scraper 12 to pass smoothly through the obstruction. The scraper 12 then compresses the spring 10 by the limiting block 11. After the connecting block 2 is inserted to a certain depth, the scraper 12 is reset and ejected by the elastic force of the spring 10. The end of the scraper 12 away from the limiting block 11 is then in close contact with the inner wall of the endotracheal tube. Then, the connecting rod 1 is pulled back by the handle 5. The connecting rod 1, along with the connecting block 2, is pulled back, allowing the scraper 12 to scrape away the sputum crusts from the inner wall of the endotracheal tube. By repeating the scraping operation several times, the sputum crusts from the inner wall of the endotracheal tube can be easily scraped and cleaned, ensuring that the inside of the endotracheal tube is unobstructed.
