[0041] Embodiment 1

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a sputum suction tube 100, which is mainly used to remove sputum in a human tracheal tube 200. The sputum suction tube 100 includes a tube body 110 and an elastic scraping portion 120.

[0043] One end of the tube body 110 is inserted into the endotracheal tube 200 and is provided with a first suction port 111 for suctioning sputum, and the other end is provided with a negative pressure interface 112 for connecting to a negative pressure device.

[0044] The elastic scraper 120 is disposed on the outer circumferential wall of the tube body 110 and abuts against the inner circumferential wall of the tracheal tube 200 .

[0045] The sputum suction tube 100 provided in the embodiment of the present application is configured such that one end of the tube body 110 is inserted into the endotracheal tube 200 and is provided with a first suction port 111 for suctioning sputum, and a negative pressure interface 112 for connecting to a negative pressure device is provided at the other end of the tube body 110, so that under the negative pressure suction action of the negative pressure device, the sputum in the endotracheal tube 200 can enter the negative pressure device through the first suction port 111 and the tube body 110 in sequence, thereby achieving the function of clearing the sputum in the endotracheal tube 200.

[0046] At the same time, an elastic scraping portion 120 is provided on the outer circumferential wall of the tube body 110 so as to abut against the inner circumferential wall of the tracheal tube 200. When the tube body 110 moves in the tracheal tube 200, the elastic scraping portion 120 can be driven to move synchronously, so that the dried and crusted sputum on the inner wall of the tracheal tube 200 can be thoroughly scraped and cleaned under the scraping action of the elastic scraping portion 120, thereby effectively improving the sputum clearing effect.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the present application, one end of the elastic scraping portion 120 close to the first suction port 111 is connected to the outer circumferential wall of the tube body 110, and the other end is inclined toward the negative pressure interface 112 along the axial direction away from the tube body 110 and abuts against the inner circumferential wall of the tracheal tube 200.

[0048] In this embodiment, one end of the elastic scraper 120 close to the first suction port 111 is connected to the outer circumferential wall of the tube body 110, and the connection can be made in an integral manner, and the other end of the elastic scraper 120 is tilted toward the negative pressure interface 112 away from the axial direction of the tube body 110 and abuts against the inner circumferential wall of the tracheal tube 200 to form a receiving groove 121 for receiving sputum, so that the sputum scraped off the inner wall of the tracheal tube 200 can fall into the receiving groove 121 along the inclined surface and be collected. The technical problem that the sputum on the inner wall of the trachea 200 is loosened due to suction in the prior art, so that this part of the sputum falls into the human lungs again, resulting in an increased chance of lung infection, is avoided.

[0049] like Figure 2As shown, in the above embodiment of the present application, the inclination angle of the elastic scraping portion 120 is a, which satisfies 30 degrees ≤ a ≤ 60 degrees.

[0050] In this embodiment, by controlling the inclination angle a of the elastic scraping portion 120 to be between 30 degrees and 60 degrees, on the one hand, it can avoid the technical problem that the elastic scraping portion 120 cannot abut against the inner wall of the endotracheal tube 200 due to a small inclination angle, thereby affecting the scraping effect; on the other hand, it can avoid the technical problem that the depth of the receiving groove 121 is too shallow due to a large inclination angle, thereby affecting the collection effect of sputum.

[0051] Exemplarily, the inclination angle a of the elastic scraping portion 120 can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, etc., and can be specifically designed according to the actual needs of the product, which will not be listed here one by one.

[0052] like Figure 2 and Figure 3 As shown, in the above embodiment of the present application, the elastic scraping portion 120 and the tube body portion 110 define a receiving groove 121 for receiving sputum, and a third suction port 115 is provided at the bottom of the receiving groove 121, and the third suction port 115 is respectively connected to the receiving groove 121 and the tube body portion 110, and a plurality of the third suction ports 115 are provided, and the plurality of third suction ports 115 are spaced apart along the circumference of the tube body portion 110.

[0053] In this embodiment, the elastic scraping portion 120 and the tube body portion 110 define a receiving groove 121 for receiving sputum. A third suction port 115 is provided at the bottom of the receiving groove 121, which is connected to the receiving groove 121 and the tube body portion 110 respectively. In this way, the dried and crusted sputum scraped off the inner wall of the tracheal tube 200 by the elastic scraping portion 120 can fall into the receiving groove 121 along the inclined surface and be collected. The dried and crusted sputum collected in the receiving groove 121 can enter the negative pressure device through the third suction port 115 and the tube body portion 110 in sequence, thereby achieving the function of completely removing the sputum in the tracheal tube 200.

[0054] By setting the number of the third suction ports 115 to be multiple and arranging the multiple third suction ports 115 at intervals along the circumference of the tube body 110, the suction effect and efficiency of the dried sputum collected in the receiving groove 121 are improved, so that the dried sputum collected in the receiving groove 121 can be completely removed.

[0055] like Figure 2 and Figure 3 As shown, in the above embodiment of the present application, a plurality of the elastic scraping portions 120 are provided, and the plurality of the elastic scraping portions 120 are arranged at intervals along the axial direction of the tube body portion 110 .

[0056] In this embodiment, by setting the number of elastic scraping parts 120 to be multiple, and arranging the multiple elastic scraping parts 120 at intervals along the axial direction of the tube body 110, when the tube body 110 moves in the tracheal tube 200, it can drive the multiple elastic scraping parts 120 to move synchronously, so that the dried and crusted sputum on the inner wall of the tracheal tube 200 can be thoroughly scraped and cleaned under the scraping action of the multiple elastic scraping parts 120, thereby further improving the scraping effect of the dried and crusted sputum on the inner wall of the tracheal tube.

[0057] In the above-mentioned embodiment of the present application, the elastic scraping portion 120 and the tube body portion 110 are made of rubber or silicone material and are integrally formed.

[0058] In this embodiment, the elastic scraping portion 120 and the tube body 110 are integrally formed of rubber or silicone material. On the one hand, this can effectively improve the connection stability between the elastic scraping portion 120 and the tube body 110, thereby ensuring the stability of the scraping effect. On the other hand, it can eliminate the installation structure and installation steps between the elastic scraping portion 120 and the tube body 110, which is beneficial to improving installation efficiency and saving costs.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the present application, the circumferential wall of the tube body portion 110 is provided with a second suction port 113 for suctioning sputum, and the second suction port 113 is located between the elastic scraping portion 120 and the first suction port 111 .

[0060] In this embodiment, a second suction port 113 for sucking sputum is provided on the circumferential wall of the tube body 110, and the second suction port 113 is located between the elastic scraping portion 120 and the first suction port 111, so that sputum in the endotracheal tube 200 can enter the tube body 110 through the first suction port 111 and the second suction port 113, and enter the negative pressure device through the tube body 110, the first suction port 111 realizes bottom suction, and the second suction port 113 realizes side suction, so that the sputum clearing effect is further improved under the joint action of the first suction port 111 and the second suction port 113.

[0061] In the above embodiment of the present application, a plurality of the second suction ports 113 are provided, and the plurality of the second suction ports 113 are arranged at intervals along the circumferential direction and / or axial direction of the tube body 110 .

[0062] In this embodiment, the number of the second suction ports 113 is set to be multiple, and the multiple second suction ports 113 are spaced apart along the circumferential direction and / or axial direction of the tube body 110, so that the sputum on the inner wall of the tracheal tube 200 is suctioned in all directions under the action of the multiple second suction ports 113, thereby further improving the sputum removal effect. The action of rotating the sputum suction tube 100 left and right during the sputum suction process in the prior art is abandoned or reduced, which reduces stimulation, relieves the patient's pain, and increases the patient's comfort.

[0063] like Figure 1 , Figure 2 and Figure 3 As shown, in any of the above embodiments of the present application, an oxygen supply interface 114 for connecting to an oxygen supply device is provided at one end of the tube body 110 away from the first suction port 111 .

[0064] In this embodiment, an oxygen supply interface 114 for connecting to an oxygen supply device is provided at one end of the tube body 110 away from the first suction port 111, so that oxygen from the oxygen supply device can enter the tube body 110 through the oxygen supply interface 114, thereby continuously supplying oxygen to the patient during the suction process, thereby reducing the hypoxia complications caused by suction and increasing the patient's comfort. The technical problem of disconnecting oxygen or ventilator during suction in the prior art, which causes complications such as hypoxia and increases the patient's pain, is avoided. At the same time, moist oxygen can help soften sputum crusts, which is conducive to subsequent peeling.

[0067] The sputum suction device has the sputum suction tube 100 in any of the above embodiments, and thus has all the beneficial effects of the sputum suction tube 100, which will not be described in detail here.

[0068] In summary, by inserting one end of the tube body 110 into the tracheal tube 200 and providing a first suction port 111 for sucking sputum, and providing a negative pressure interface 112 for connecting to the negative pressure device at the other end of the tube body 110, the sputum in the tracheal tube 200 can enter the negative pressure device through the first suction port 111 and the tube body 110 in sequence under the negative pressure suction of the negative pressure device, thereby achieving the function of clearing the sputum in the tracheal tube 200. At the same time, by providing an elastic scraping portion 120 abutting against the inner circumferential wall of the tracheal tube 200 on the outer circumferential wall of the tube body 110, when the tube body 110 moves in the tracheal tube 200, the elastic scraping portion 120 can be driven to move synchronously, so that the dried and crusted sputum on the inner wall of the tracheal tube 200 can be thoroughly scraped and cleaned under the scraping action of the elastic scraping portion 120, thereby effectively improving the sputum clearing effect.
