Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a suction tube with anti-blocking function. Background Technology

[0002] A suction catheter is a medical device primarily used to help patients who cannot expel respiratory secretions (such as sputum, blood, vomit, etc.) on their own to clear their airways and maintain airway patency. Suction catheters are typically made of soft, flexible medical-grade plastic to ensure they do not damage the patient's respiratory mucosa during use. They are designed in different diameters and lengths to accommodate different patient needs and suction sites. One end of the suction catheter connects to a negative pressure suction device, which generates negative pressure to aspirate sputum; the other end is inserted into the patient's airway for suctioning.

[0003] When using the above-mentioned technology, the following technical problems were found in the existing technology: When using the suction catheter, due to the stickiness of sputum, the sputum may stick to the suction catheter during the suctioning process, causing blockage. The blockage of the suction catheter may lead to incomplete suctioning, with sputum remaining in the patient's airway, increasing the patient's discomfort. At the same time, medical staff need to spend more time and effort to clear the blocked suction catheter, thus prolonging the suctioning operation time. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the suctioning process, sputum adheres to the suction tube, causing blockage. This blockage can lead to incomplete suctioning, leaving sputum in the patient's airway and increasing patient discomfort. Furthermore, medical staff need to spend more time and effort clearing the blocked suction tube, thus prolonging the suctioning procedure.

[0005] The present invention discloses a suction tube with anti-clogging function, comprising a reservoir bag, a negative pressure pump installed on the reservoir bag, a connecting tube installed at the end of the reservoir bag away from the negative pressure pump, a connecting hose inserted at the end of the connecting tube away from the reservoir bag, a sealing component and a flushing component installed inside the connecting hose, and a suction tube body installed at the end of the connecting hose away from the connecting tube. The sealing component includes a first air inlet pipe, which is installed and connected to the internal cavity of the hose and extends into the internal cavity of the suction tube body. A first hose and a spherical air bag are respectively installed at both ends of the first air inlet pipe.

[0006] A compression balloon is installed at the end of the first tubing away from the first air inlet tube. The first air inlet tube penetrates the inner wall of the connecting tubing and extends into the main body of the suction tube at one end located inside the inner cavity of the connecting tubing. The spherical balloon is located inside the main cavity of the suction tube.

[0007] The flushing assembly includes a first water inlet pipe that penetrates the inner wall of a connecting hose. A cylindrical balloon and a water outlet are respectively installed at both ends of the first water inlet pipe. A connecting water pipe is installed at the end of the cylindrical balloon away from the first water inlet pipe. A one-way valve is installed in both the connecting water pipe and the first hose.

[0008] The water outlet head is ring-shaped and has several through holes. The first water inlet pipe and the first air inlet pipe are installed on the same mounting bracket at one end inside the suction tube body.

[0009] The one-way valve includes a mounting bracket and a mounting ring. The mounting brackets and mounting rings of the two one-way valves are respectively installed in the connecting water pipe and the first flexible hose. A sliding rod is slidably connected to the mounting bracket. A piston pad is installed at one end of the sliding rod after it passes through the mounting ring. A return spring is installed on the sliding rod. The other end of the return spring is connected to the mounting bracket.

[0010] Elastic bands are installed on both sides of the liquid storage bag, and Velcro is installed on the elastic bands. A handle is installed on the liquid storage bag.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by squeezing and pressing the balloon, the spherical balloon expands and blocks the inner cavity of the suction tube body, effectively sealing the inner wall and inlet of the suction tube. Subsequently, by squeezing the cylindrical balloon, flushing water is pumped into the suction tube body to dilute the sputum, significantly reducing the adhesion of sputum to the inner wall of the tube, making it easier to suction out the sputum.

[0012] The device allows for flushing after the patient's suctioning is completed, or flushing during the suctioning process as needed. This flexibility allows medical staff to adjust the flushing timing according to the actual situation, thereby better meeting the patient's needs. Because the sputum is diluted, the suction tube can be suctioned more smoothly when the negative pressure pump is restarted, avoiding suctioning difficulties caused by thick sputum. This improves suctioning efficiency, reduces operation time, and also reduces the workload of medical staff. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] like Figures 1-5 As shown, a suction tube with anti-clogging function includes a reservoir bag 1, a negative pressure pump 2 installed on the reservoir bag 1, a connecting tube 3 installed at the end of the reservoir bag 1 away from the negative pressure pump 2, a connecting hose 4 inserted at the end of the connecting tube 3 away from the reservoir bag 1, a sealing component and a flushing component installed inside the connecting hose 4, and a suction tube body 5 connected to the end of the connecting hose 4 away from the connecting tube 3. The sealing component includes a first air inlet pipe 10, which penetrates the inner wall of the connecting hose 4 and extends into the suction tube body 5 at one end located inside the inner cavity of the connecting hose 4. A first hose 7 and a spherical air bag 9 are respectively installed at both ends of the first air inlet pipe 10.

[0025] During operation, align the inlet of the suction catheter body 5 with the patient's sputum, then start the negative pressure pump 2. The negative pressure pump 2, through the connecting hose 4 on the connected storage bag 1, creates negative pressure inside the suction catheter body 5 connected to the connecting hose 4, thereby drawing in the sputum aligned with the inlet of the suction catheter body 5 and allowing the sputum to enter the storage bag 1. If blockage occurs, the spherical airbag 9 on the sealing component can be used to block the suction catheter body 5, and then the flushing component can be used to flush and dilute the sputum inside the suction catheter body 5 or the connecting hose 4, while also flushing to reduce the amount of sputum adhering to the suction catheter body 5 or the connecting hose 4.

[0026] like Figures 1-5 As shown, a compression balloon 6 is installed at the end of the first flexible tube 7 away from the first air inlet tube 10. A spherical airbag 9 is disposed in the inner cavity of the suction tube body 5. The flushing assembly includes a first water inlet tube 13, which penetrates the inner wall of the connecting flexible tube 4. A cylindrical balloon 11 and a water outlet 14 are respectively installed at both ends of the first water inlet tube 13. A connecting water pipe 12 is installed at the end of the cylindrical balloon 11 away from the first water inlet tube 13. A one-way valve is installed in both the connecting water pipe 12 and the first flexible tube 7. The water outlet 14 is annular and has several through holes 15. When water is sprayed out of the water outlet 14, it is sprayed out through the several through holes 15. The first water inlet tube 13 and the first air inlet tube 10 are disposed in the inner cavity of the suction tube body 5 and are mounted on the same mounting bracket 8. The mounting bracket 8 is used to fix the first water inlet tube 13 and the first air inlet tube 10 in the inner cavity of the suction tube body 5.

[0027] During suctioning, when sputum adheres to the inner wall of the tube, first stop the negative pressure pump 2, and then stop suctioning the main body 5 of the suction tube. Next, squeeze the compression balloon 6 on the sealing assembly. The compression balloon 6 pumps air into the first air inlet pipe 10 through the one-way valve on the connecting hose 4, and then the first air inlet pipe 10 pumps the air into the spherical airbag 9, causing the spherical airbag 9 to inflate and expand, blocking the inner cavity of the main body 5 of the suction tube, thus sealing the inner wall of the main body 5 and sealing its inlet. Then, connect the external water pipe to the connecting hose 4, and squeeze the cylindrical balloon 11, so that the cylindrical balloon 11 pumps flushing water into the first water inlet pipe 13 through the one-way valve in the connecting hose 4. Then, the first inlet pipe 13 pumps the flushing water into the suction tube body 5 through the outlet 14, diluting the flushing water with the sputum. Then, the negative pressure pump 2 is turned on to drive the flushing water to flush the inner wall of the suction tube body 5 and the connecting hose 4. Finally, the flushing liquid enters the storage bag 1. The flushing of the tube can be done after the patient's sputum suction is completed or during the patient's sputum suction, effectively reducing the adhesion of sputum to the inner wall of the tube and affecting the sputum suction. The flushing process also helps to keep the tube clean and unobstructed. By gently pressing the balloon 6, the one-way valve is gently opened, allowing the gas connected to the balloon 9 in the first air inlet pipe 10 to be discharged through the air inlet of the balloon 6.

[0028] The device allows for rinsing after the patient's suctioning is completed, or rinsing during the suctioning process as needed. This flexibility allows healthcare professionals to adjust the timing of rinsing according to the actual situation, thereby better meeting the patient's needs.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the one-way valve includes a mounting bracket 16 and a mounting ring 17. The mounting brackets 16 and mounting rings 17 of the two one-way valves are respectively installed in the connecting water pipe 12 and the first flexible hose 7. A sliding rod 18 is slidably connected to the mounting bracket 16. A piston pad 20 is installed at one end of the sliding rod 18 after passing through the mounting ring 17. A return spring 19 is installed on the sliding rod 18. The other end of the return spring 19 is connected to the mounting bracket 8.

[0030] In use, the sliding rod 18 on the one-way valve slides on the fixed frame 16 as the pressing balloon 6 or cylindrical balloon 11 is pressed, so that the sliding rod 18 drives the piston pad 20 to open at the mounting ring 17, and the return spring 19 drives the piston pad 20 on the sliding rod 18 to close on the mounting ring 17, thereby reducing the backflow of air or water into the pressing balloon 6 and cylindrical balloon 11;

[0031] Elastic bands 21 are installed on both sides of the liquid storage bag 1. Velcro 22 is installed on the elastic bands 21. Because of its elasticity, the elastic bands 21 can fix the liquid storage bag 1 as needed to ensure its stability in different situations. The design of the Velcro 22 makes fixing and unfixing faster and more convenient. Users can easily adjust the position or tightness of the liquid storage bag 1 according to the actual situation. A handle 23 is installed on the liquid storage bag 1. The design of the handle 23 allows users to easily lift and move the liquid storage bag 1.

[0032] Working principle: During suctioning, when sputum adheres to the inner wall of the tube, the negative pressure pump 2 is first stopped, thus stopping the suction tube body 5. Then, the compression balloon 6 on the sealing assembly is squeezed. The compression balloon 6 pumps gas into the first air inlet tube 10 through the one-way valve on the connecting hose 4. The first air inlet tube 10 then pumps the gas into the spherical airbag 9, causing the spherical airbag 9 to inflate and expand, blocking the inner cavity of the suction tube body 5. This seals the inner wall of the suction tube body 5 and the inlet. The external water pipe is then connected to the connecting hose 4. Finally, the cylindrical balloon 11 is squeezed, allowing the cylindrical balloon 11 to... The one-way valve inside the connecting hose 4 directs the flushing water pump into the first inlet pipe 13, and then the first inlet pipe 13 pumps the flushing water through the outlet head 14 into the suction tube body 5, diluting the sputum with the flushing water. Then, the negative pressure pump 2 is turned on to drive the flushing water to flush the inner walls of the suction tube body 5 and the connecting hose 4. Finally, the flushing liquid enters the storage bag 1. Flushing the tubing can be done after the patient's sputum suction is completed or during the patient's sputum suction, effectively reducing the number of tubing tubes that are stuck to the inner wall due to sputum, thus affecting the sputum suction. The flushing process also helps to keep the tubing clean and unobstructed.
