Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a whole lung lavage endotracheal tube converter. Background Technology
[0002] "Large-volume whole lung lavage" can treat occupational lung diseases such as silicosis, coal worker's pneumoconiosis, cement worker's pneumoconiosis, electric welder's lung, and foundry worker's pneumoconiosis. Under general anesthesia via intravenous injection, the doctor inserts a Y-shaped double-lumen endotracheal tube through the patient's mouth to separate the left and right lungs, primarily for air-water separation. After the tube is inserted, lavage can begin. The lavage bottle is suspended approximately 50cm above the patient's head and connected to an infusion set. The tip of the infusion set is usually cut off with scissors. During lavage, the tip of the infusion set is inserted into the endotracheal tube. The operator must hold the infusion set continuously throughout the process. Each lavage cycle (in and out) takes approximately 3-6 minutes. The number of lavage cycles depends on the individual patient and the specific condition, but the principle is to continue lavage until the final drainage fluid is essentially clear. Therefore, current techniques require inserting an infusion set or blood transfusion set into the endotracheal tube, which is inconvenient for medical staff. Utility Model Content
[0003] This invention addresses the technical problem of inconvenient connection between the infusion set and endotracheal tube during existing whole lung lavage procedures by providing a whole lung lavage endotracheal tube converter. The converter includes a vertically positioned main tube, open at both ends. The main tube can be designed with inner diameters of 5mm, 7mm, 9mm, 10mm, 11mm, and 12mm for easy connection to currently used clinical ventilator tubing. The top of the main tube has a frustum-shaped protrusion. An exhaust pipe is fixed to the left side of the protrusion, and a first plug is detachably mounted on the top of the exhaust pipe. This allows for ventilation during lavage and closure during aspiration. Opening the first plug during lavage allows for the smooth expulsion of residual air from the lungs, while closing the first plug during aspiration maintains a negative pressure and a sealed aspiration process. A support tube is located on the right side of the protrusion, with a second plug detachably mounted on the top of the support tube. This allows for the insertion and removal of a suction catheter, facilitating the extraction of lavage fluid from the support tube and direct insertion of the suction catheter, reducing the frequency of direct endotracheal intubation. The bottom ends of both the exhaust pipe and the support pipe extend downwards into the interior of the protrusion. A vertically installed connecting pipe is fixed to the top of the protrusion. The upper end of the connecting pipe is detachably equipped with a connector for connecting an infusion set. The connector uses a Klappe connector (Klappe connectors are part of the Klappe needle-free infusion series. With its unique design, it can connect syringes, infusion sets, and blood transfusion sets, and is especially used for patients receiving intravenous infusions, such as children, critically ill patients, chemotherapy patients, patients requiring continued resuscitation, and patients with water and electrolyte imbalances). Using a Klappe connector can effectively ensure that pulmonary lavage fluid is connected to the Klappe connector in an aseptic manner, meeting the clinical requirements of both ordinary infusion set nipples and blood transfusion set nut-type rotatable connection ports. Because the connection to the Klappe connector is airtight, it can effectively avoid occupational exposure caused by splashing during the lavage process.
[0004] Preferably, the main pipe, protrusion, and connecting pipe are all made of transparent PVC material, which makes it easy to observe the amount of flushing fluid.
[0005] Preferably, the diameter of the main pipe is larger than the diameter of the connecting pipe.
[0006] Preferably, the length of the main tube is 16mm, which allows it to fit tightly against the inner wall of the endotracheal tube interface while ensuring its stability.
[0007] Preferably, the upper end of the main tube is provided with two symmetrically arranged handles, which are located on both sides of the main tube. The handles are designed to facilitate the operator's grip when connecting the tube, avoiding the inconvenience caused by the overly smooth surface due to the cylindrical design.
[0008] The above-mentioned approach has the following advantages: The design of the exhaust pipe and the first plug allows for the release of air during lavage and closure during extraction. Opening the first plug during lavage enables the smooth expulsion of residual air from the lungs, while closing the first plug during extraction maintains a negative pressure and a sealed extraction process. The support tube and the second plug facilitate the insertion and removal of the suction catheter, allowing for easy extraction of lavage fluid from the support tube and direct insertion into the suction catheter, reducing the frequency of direct endotracheal intubation. The connector design ensures aseptic connection of pulmonary lavage fluid to the Kelp connector, meeting clinical requirements for both standard infusion set nipples and transfusion set nut-type rotatable connections. The airtight Kelp connector effectively prevents occupational exposure caused by splashing during lavage. The main pipe, protrusions, and connecting tubes are made of transparent PVC material for easy observation of the lavage fluid volume. Attached Figure Description

[0011] like Figure 1-2As shown, a whole lung lavage endotracheal tube converter includes a vertically positioned main tube 1, with both ends of the main tube 1 open. The main tube 1 can be designed with an inner diameter of 5mm, 7mm, 9mm, 10mm, 11mm, or 12mm to facilitate connection to currently used ventilator tubing. The top of the main tube 1 is connected to a frustum-shaped protrusion 2. An exhaust tube 3 is fixed to the left side of the protrusion 2. A first plug 31 is detachably mounted on the top of the exhaust tube 3, allowing for air release during lavage and closure during suction. Opening the first plug 31 during lavage allows for the smooth expulsion of residual air from the lungs, while closing the first plug 31 during suction maintains a negative pressure during the suction process. A support tube 4 is located on the right side of the protrusion 2. A second plug 41 is detachably mounted on the top of the support tube 4, allowing for the insertion and removal of a suction catheter. This facilitates the extraction of lavage fluid from the support tube 4 and direct insertion of the suction catheter, reducing the frequency of direct endotracheal intubation. The bottom ends of the exhaust pipe 3 and the support pipe 4 both extend downward into the interior of the protrusion 2. A vertically arranged connecting pipe 5 is fixed to the top of the protrusion 2. The upper end of the connecting pipe 5 is detachably equipped with a connector 51 for connecting an infusion set. The connector 51 is a Kluck connector (Kluck connector is a product of the Kluck needleless infusion series. With its unique design, it can connect syringes, infusion sets and blood transfusion sets, especially for patients receiving intravenous infusions, such as children, critically ill patients, chemotherapy patients, patients who need to continue resuscitation, and patients with water and electrolyte imbalances). Using the Kluck connector can effectively ensure that the pulmonary lavage fluid is connected to the Kluck connector in accordance with aseptic requirements, meeting the clinical needs of both ordinary infusion set nipples and blood transfusion set nut-type rotatable connection ports. Because the connection to the Kluck connector is airtight, it can effectively avoid occupational exposure caused by splashing during the lavage process.
[0012] Preferably, the main pipe 1, the protrusion 2, and the connecting pipe 5 are all made of transparent PVC material, which makes it easy to observe the amount of rinsing fluid.
[0013] Preferably, the diameter of the main pipe 1 is larger than the diameter of the connecting pipe 5.
[0014] Preferably, the length of the main tube 1 is 16mm, which satisfies the requirement of a tight fit with the inner wall of the endotracheal tube interface, while ensuring its stable fixation.
[0015] Preferably, the upper end of the main pipe 1 is provided with two symmetrically arranged handles 11, which are located on both sides of the main pipe 1. The handles 11 are designed to facilitate the operator's grip during docking and avoid the inconvenience caused by the overly smooth surface due to the cylindrical design.
[0016] Usage process: In use, after the anesthesiologist inserts a double-lumen endotracheal tube, the upper end of the tube 1 is connected to the lower end of the main tube 1 on the side requiring lavage. The lavage fluid is then connected to the connector 51 at the upper end of the connecting tube 5. The first plug 31 on the exhaust tube 3 is opened, and the second plug 41 on the support tube 4 is fixed to the support tube 4. The patient's lungs are then lavaged with the lavage fluid. After a single lavage, the exhaust tube 3 is closed with the first plug 31, and the second plug 41 on the support tube 4 is opened. An external suction catheter is inserted into the main tube 1 through the support tube 4, and the lavage fluid is aspirated back. After this aspiration, a second lavage is performed until the aspirated lavage fluid is clear.
