Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a whole lung lavage catheter device. Background Technology
[0002] Whole lung lavage is an important medical procedure specifically used to treat occupational lung diseases such as pneumoconiosis. This technique involves injecting saline or other specialized solutions into the patient's lungs and then draining them to remove dust particles and other harmful substances deposited in the alveoli, thereby relieving symptoms and improving respiratory function. Although this technique has achieved significant clinical therapeutic effects, some problems still need to be addressed in its practical application.
[0003] First, the temperature control of existing whole lung lavage fluids is not precise enough during use. This can result in the fluid being too cold or too hot when it enters the body, causing patient discomfort or even potential tissue damage. For example, if the fluid temperature is too low, it may cause vasoconstriction and circulatory problems; while if the temperature is too high, it may cause heat damage to the lungs. Therefore, ensuring that the lavage fluid is maintained within a suitable and constant temperature range has become an important issue.
[0004] Secondly, during whole lung lavage, air bubbles can easily be introduced due to improper operation. These tiny bubbles, injected into the patient's lungs along with the fluid, can potentially cause pneumothorax or lung infection, further increasing the risks associated with anesthesia—an extremely dangerous situation that can be life-threatening in severe cases. In conclusion, while whole lung lavage plays an important role in treatment, many issues still require improvement. Utility Model Content

[0040] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0041] Reference Appendix Figure 1 To be continued Figure 3 As shown in the illustration, a whole lung lavage catheter device 100 according to an embodiment of this application is shown. The whole lung lavage catheter device 100 includes an lavage tube 2, an lavage fluid temperature controller 3, a drip chamber 4, an lavage tube main valve 5, a connecting member 6, a return tube 8, and a double-lumen endotracheal tube 9. The lavage tube 2 is installed through the lavage fluid temperature controller 3. The drip chamber 4 is connected below the lavage tube 2. The lavage tube main valve 5 is disposed between the connecting member 6 and the drip chamber 4. The return tube 8 and the double-lumen endotracheal tube 9 are connected to the other end of the connecting member 6. The flushing fluid temperature controller 3 is used to heat the flushing fluid in the irrigation tube 2 so that the flushing fluid temperature reaches a suitable temperature for flushing. The flushing fluid then flows through the drip chamber 4 and the main valve of the irrigation tube 5, through the connecting piece 6, and into the double-lumen endotracheal tube 9 for lung flushing. The temperature of the flushing fluid after being heated by the flushing fluid temperature controller 3 helps to reduce the contraction of pulmonary blood vessels during flushing, avoids vasoconstriction and blood circulation problems caused by low temperature, reduces the discomfort caused to the patient by temperature changes during flushing, and improves the patient's comfort.
[0042] In detail, the irrigation tube 2 includes a first irrigation cannula section 21, a second irrigation cannula section 22, a Y-shaped connector 23, and a heating section 24. The first irrigation cannula section 21 and the second irrigation cannula section 22 are connected to the upper end of the Y-shaped connector 23, and the heating section 24 is connected to the lower end of the Y-shaped connector 23. The first irrigation cannula section 21, the second irrigation cannula section 22, and the heating section 24 are all made of silicone or polyurethane material, which has a certain heat resistance while ensuring its flexibility and structural strength. Those skilled in the art should understand that the first irrigation cannula section 21, the second irrigation cannula section 22, and the heating section 24 can also be made of other materials, including but not limited to the materials listed above.
[0043] The whole lung lavage catheter device 100 also includes an lavage tube connector 211. There are two lavage tube connectors 211, which are respectively installed at the ends of the first lavage tube segment 21 and the second lavage tube segment 22, and are located at the end away from the Y-type connector 23. The lavage tube connector 211 is used to be inserted into the lavage bottle. The lavage fluid in the lavage bottle flows from the lavage tube connector 211 into the first lavage tube segment 21 and the second lavage tube segment 22, and is then combined by the Y-type connector 23 and flows into the heating section 24.
[0044] like Figure 2 As shown, the flushing fluid temperature controller 3 includes a main body 31, a constant temperature heating unit 32, a constant temperature controller 33, and a power supply component 34. The constant temperature controller 33 is installed on the main body 31. The constant temperature heating unit 32 extends from both sides of the main body 31 to form a hollow cylinder for accommodating the heating section 24. The power supply component 34 is connected to the constant temperature controller 33 and the constant temperature heating unit 32 for power supply.
[0045] It is understood that the power supply component 34 can be implemented as a removable battery to suit use in complex environments, reduce power supply requirements, and provide independent power to the constant temperature heating unit 32. This allows the temperature of the constant temperature heating unit 32 to rise and transfer heat to the heating section 24, so that the temperature of the rinsing fluid within the heating section 24 reaches a predetermined temperature. The power supply component 34 can also be implemented as an external power supply for long-term rinsing operations, maintaining a stable rinsing fluid temperature during rinsing, which helps mitigate the risks posed by temperature changes to the patient's lung tissue.
[0046] The thermostat 33 is used to adjust the temperature of the thermostat heating unit 32 so that the temperature of the thermostat heating unit 32 is maintained at around 37°C. The thermostat 33 is also equipped with an adjustment button for slightly adjusting the heating temperature of the thermostat heating unit 32, further improving the heating stability of the thermostat heating unit 32 and helping to maintain the temperature of the rinsing fluid.
[0047] Reference Appendix Figure 3 As shown, the drip pot 4 further includes a sealing member 43 and a baffle 44. The drip pot 4 has an inlet 41 and an outlet 42 formed at both ends. The inlet 41 connects to the heating section 24. The baffle 44 is located in the lower middle part of the drip pot 4, near the outlet 42. The sealing member 43 is located at the outlet 42 and is restricted by the baffle 44; in other words, the sealing member 43 can only move within the space between the outlet 42 and the baffle 44. Specifically, as... Figure 3As shown, when there is no liquid in the drip chamber 4, the sealing member 43 sinks under the action of gravity and seals the outlet 42, preventing air from entering. When liquid flows into the drip chamber 4, the sealing member 43 floats up under the action of buoyancy, thereby opening the outlet 42, allowing the irrigation fluid to flow out through the outlet 42. In particular, the sealing member 43 is restricted by the baffle 44 during the floating process, which does not affect the inlet 41, further reducing the air bubbles in the irrigation fluid and preventing air bubbles from entering the lungs with the irrigation fluid, reducing the risk of patient injury due to air bubbles during irrigation, and preventing air bubbles from interfering with the doctor's operation, which helps to improve the efficiency of irrigation surgery.
[0048] The main irrigation valve 5 has conduits connected to both ends. One end is connected to the outlet 42 of the drip chamber 4, and the other end is connected to the connecting member 6. In this embodiment, the connecting member 6 is a Y-shaped pagoda connector 61. One end of the conduit of the main irrigation valve 5 is connected to one end of the Y-shaped pagoda connector 61, and the other two ends of the Y-shaped pagoda connector 61 are connected to the return pipe 8 and the double-lumen endotracheal tube 9, respectively. The main irrigation valve 5 is used to control the flushing fluid flowing out of the drip chamber 4.
[0049] The double-lumen endotracheal tube 9 also includes a visual connector 91 and an instrument connector 92. The visual connector 91 and the instrument connector 92 are located away from the working end of the double-lumen endotracheal tube 9 and close to the Y-shaped pagoda connector 61, that is, away from the double-lumen end of the double-lumen endotracheal tube 9. The visual connector 91 is used to connect external visual equipment to observe the flushing status of the tip of the double-lumen endotracheal tube 9, and the instrument connector 92 is used to connect other medical devices for whole lung lavage.
[0050] The whole lung lavage catheter device 100 further includes a plurality of tube control clips 7, which are installed on the first lavage cannula segment 21, the second lavage cannula segment 22, and the return tube 8 to control the opening and closing of the first lavage cannula segment 21, the second lavage cannula segment 22, and the return tube 8. In this embodiment, the tube control clip 7 is preferably a Robert clip 71. Those skilled in the art should understand that the tube control clip 7 can also be implemented as other clips, including but not limited to the situations listed above.
[0051] As attached Figures 4A to 4BThe diagram shows the working process of the whole lung lavage catheter device 100. The double-lumen endotracheal tube 9 is inserted into the patient's bronchus. The Robert clamps 71 on the first lavage tube section 21 and the second lavage tube section 22, and the main lavage valve 5 are opened. The lavage fluid flows into the first lavage tube section 21 and the second lavage tube section 22 through the lavage tube connector 211, and then converges at the Y-type connector 23 into the heating section 24. The constant temperature heating unit 32 heats the lavage fluid in the heating section 24 and allows it to flow into the drip chamber 4. The sealing member 43 floats up, and the heated lavage fluid flows into the double-lumen endotracheal tube 9 through the Y-type pagoda connector 61 for lavage. The first lavage tube section 21 and the second lavage tube section 22 are then closed sequentially. The Robert clamp 71 on the irrigation cannula section 22 and the main irrigation valve 5, the sealing element 43 lowers as the irrigation fluid flows out, thereby closing the outlet 42, and the Robert clamp 71 on the return tube 8 is opened. The irrigation fluid flows with the double-lumen endotracheal tube 9 through the Y-shaped pagoda connector 61 to the return tube 8, thus discharging the irrigation fluid. This cycle is repeated multiple times to complete the irrigation of the lungs. It is understood that the irrigation fluid heated by the constant temperature heating unit 32 helps to reduce the contraction of pulmonary blood vessels during the irrigation process, avoids vasoconstriction and blood circulation problems caused by low temperature, reduces the discomfort caused to the patient by temperature changes during the irrigation process, and thus improves the patient's comfort.
[0052] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
