Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a bronchoalveolar lavage device. Background Technology

[0002] Bronchoalveolar lavage is a new technique developed based on fiberoptic bronchoscopy. It involves injecting physiological saline into the bronchi and alveoli using a bronchoscope and then immediately aspirating it to collect the effective fluid from the alveolar surface for examination of its cellular components and soluble substances. There are two methods: unilateral whole-lung lavage under general anesthesia via a Karen double-lumen tube, and lavage via fiberoptic bronchoscopy. Clinically, it is used for the diagnosis and differential diagnosis of various lung diseases, such as alveolitis, pulmonary fibrosis, asbestosis, lung cancer, Pneumocystis jirovecii disease, and pulmonary alveolar proteinosis, as well as for studying the etiology, pathogenesis, evaluation of treatment efficacy, and prognosis of lung diseases.

[0003] During bronchoalveolar lavage, containers are needed to collect the extracted lavage fluid. Since the lavage fluid extraction is not completed in one go, it often needs to be extracted multiple times. Each extracted lavage fluid needs to be stored separately. In practice, doctors need to repeatedly change containers, repeatedly take out containers, connect them to the catheter, and disconnect them after extraction. This is inefficient, and slight carelessness may lead to problems such as the container tipping over, falling, and liquid spillage. Therefore, a bronchoalveolar lavage device is needed to solve the above problems. Utility Model Content

The irrigation fluid is injected into the storage tank by inserting a guide tube from the guide assembly into the inlet pipe on the top surface of the storage tank. When replacing a storage tank, lifting the handle moves the lifting plate upward. The lifting plate, through the lifting block, moves the lifting ring upward. The upward movement of the lifting ring compresses the second spring, causing the guide tube to move upward and disengage from the inlet pipe. Then, pulling the handle controls the moving cylinder to move within the moving slot, which moves the guide tube above another storage tank. Under the rebound force of the second spring, the guide tube can be driven downward to insert into the inlet pipe on the top surface of another storage tank, completing the replacement of the storage tank. The overall operation is very convenient and quick, eliminating the need to repeatedly pick up and drop the storage tank, simplifying the operation steps, and improving efficiency.

The stabilizing plate can ensure that the liquid storage tank will not tip over or fall to the ground, ensuring the safety of the internal flushing liquid. The connecting block on the side wall of the stabilizing plate is located inside the rectangular groove on the outer wall of the storage frame. The lower end of the connecting rod is fixedly connected to the connecting block. The tension of the first spring ensures that the connecting rod will not move downward, so the stabilizing plate will not move downward accidentally. By pressing the stabilizing plate, the first spring is stretched, and the stabilizing plate can be moved down to a lower position on the outside of the liquid storage tank, thereby facilitating the removal of the liquid storage tank from the inside of the storage frame. This ensures both safety and facilitates the removal of the liquid storage tank. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 As shown, this utility model provides the following technical solution: a bronchoalveolar lavage device, including a storage frame 1, a placement groove 12 on the inner bottom surface of the storage frame 1 for placing a storage tank 3, a storage tank 3 inside the placement groove 12 for storing lavage fluid, an inlet pipe 31 fixed in the middle of the top surface of the storage tank 3 for connecting to a guide pipe 22 to inject lavage fluid into the inside of the storage tank 3, the inlet pipe 31 communicating with the inside of the storage tank 3, both the storage tank 3 and the inlet pipe 31 being made of transparent material, the storage frame 1 of this solution can accommodate multiple storage tanks 3 inside, thus facilitating doctors to repeatedly extract lavage fluid from the patient's body.

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the top surface of the storage frame 1 is provided with a movable groove 11 for the horizontal movement of the movable cylinder 21. The movable groove 11 is connected to the inner side of the storage frame 1. The inner side of the movable groove 11 is provided with a liquid guiding assembly 2 for guiding the flushing liquid into the inner side of the storage tank 3. The liquid guiding assembly 2 includes a movable cylinder 21 and a liquid guiding pipe 22. The movable cylinder 21 is located inside the movable groove 11 and can drive the liquid guiding pipe 22 to move horizontally. A first limiting ring 211 is fixedly sleeved on the upper outer wall of the movable cylinder 21. The first limiting ring 211 is located above the movable groove 11 and can prevent the movable cylinder 21 from moving downward. The lower end of the movable cylinder 21... A second limiting ring 212 is fixedly sleeved on the outer wall. The second limiting ring 212 is located below the moving groove 11 and can prevent the moving cylinder 21 from moving upward. A liquid guide tube 22 is movably inserted into the inner side of the moving cylinder 21 for injecting flushing liquid into the inner side of the storage tank 3. The liquid guide tube 22 passes through the moving cylinder 21, and the lower end of the liquid guide tube 22 is movably inserted into the inner side of the inlet pipe 31. A lifting ring 221 is fixedly sleeved on the outer wall of the lower end of the liquid guide tube 22 for driving the liquid guide tube 22 to move up and down. The lifting ring 221 is located above the inlet pipe 31, and a second spring 225 is fixed on the top surface of the lifting ring 221 to prevent the liquid guide tube 22 from moving upward. If the lifting ring moves upward unexpectedly, the second spring 225 is sleeved on the outside of the liquid guide tube 22. The top of the second spring 225 is fixedly connected to the moving cylinder 21. A lifting block 222 is fixed to the outer wall of the lifting ring 221 to drive the lifting ring 221 upward. A lifting plate 223 is fixed to the top edge of the lifting block 222 to drive the lifting block 222 upward. The lifting plate 223 passes through the moving groove 11. A handle 224 is fixed to one side wall of the upper end of the lifting plate 223 for easy lifting. In this solution, by grasping the handle 224 and moving the lifting plate 223 upward, the lifting block 222 can be moved upward. 22 drives the lifting ring 221 to move upward. The upward movement of the lifting ring 221 compresses the second spring 225 and drives the liquid guide tube 22 to move upward. After the liquid guide tube 22 moves upward and disengages from the inside of the inlet pipe 31 on one liquid storage tank 3, the moving cylinder 21 is then moved inside the moving groove 11 by the handle 224. This moves the liquid guide tube 22 to the top of the inlet pipe 31 on another liquid storage tank 3. Under the action of the rebound force of the second spring 225, the liquid guide tube 22 moves downward and inserts into the inside of the inlet pipe 31, thus completing the replacement of the liquid storage tank 3. The operation is simple and quick, which facilitates the doctor's work and helps to improve efficiency.

[0027] Example 2

[0028] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 4As shown, specifically, the lower outer wall of the storage frame 1 is symmetrically provided with rectangular grooves 13 for accommodating the movement of the connecting block 42. The rectangular grooves 13 are connected to the inner side of the storage frame 1. A spring groove 131 is provided in the middle of the top surface of the inner side of the rectangular groove 13 for connecting the first spring 132 and the connecting rod 133. The first spring 132 is fixed to the top surface of the inner side of the spring groove 131, using elastic force to pull the stabilizing plate 4 and prevent it from accidentally moving downward. The lower end of the first spring 132 is fixed with the connecting rod 133 for connecting with the connecting block 42. The connecting rod 133 is movably inserted into the inner side of the spring groove 131. A stabilizing plate 4 is provided on the inner side of the lower end of the storage frame 1 to maintain the stability of the liquid storage tank 3. The top surface of the stabilizing plate 4 is provided with a through hole 41. The storage tank 3 is used to accommodate the liquid storage tank 3. The liquid storage tank 3 passes through the through hole 41. The side wall of the stabilizing plate 4 is symmetrically fixed with connecting blocks 42 for connecting the stabilizing plate 4 and the connecting rod 133. The lower end of the connecting rod 133 is fixed to the top surface of the connecting block 42. In this solution, the liquid storage tank 3 is restricted to the inside of the through hole 41, so that the liquid storage tank 3 will not be at risk of tipping over or falling. By pressing down the stabilizing plate 4, the connecting block 42 is driven to move down, and the connecting block 42 drives the connecting rod 133 to move down. The first spring 132 will be stretched, so that the stabilizing plate 4 can move down to the lower part of the outside of the liquid storage tank 3, so that the liquid storage tank 3 can be taken out from the inside of the storage frame 1, ensuring the safety of the liquid storage tank 3 and facilitating the disassembly and assembly of the liquid storage tank 3.

[0029] Example 3

[0030] In another embodiment of this solution, refer to Figure 1 and Figure 2 As shown, specifically, a bronchial endoscope 5 is located above the storage frame 1 (the bronchial endoscope 5 is existing technology; its specific operation and principle can be found in the existing electronic bronchial endoscope, used for lavage of the patient's lungs, therefore it is not described in detail here). A return tube 52 is fixed to the outer wall of the bronchial endoscope 5 for guiding the lavage fluid inside the guide tube 22. The return tube 52 is connected to the inner side of the bronchial endoscope 5 and is made of flexible transparent material. The lower end of the return tube 52 is fixedly connected to the guide tube 22. A suction tube 521 is fixed to the outer wall of the return tube 52 for using negative pressure to aspirate the lavage fluid. The bronchial endplate 521 is connected to the inside of the return tube 52. An injection tube 51 is fixed to the outer wall of the bronchial endplate 5 for injecting saline solution. The injection tube 51 is connected to the inside of the bronchial endplate 5 and is located above the return tube 52. In this procedure, the bronchial endplate 5 is inserted into the patient's body, and saline solution is injected into the patient's lungs through the injection tube 51 for lavage. Then, the suction tube 521 is connected to the external negative pressure device. The lavage fluid is aspirated using the principle of negative pressure, guided through the return tube 52 to the inside of the guide tube 22, and finally stored in the reservoir 3. The lavage fluid can be repeatedly extracted by intermittently activating the external negative pressure device.

[0031] The working principle and usage process of this utility model:

[0032] In use, the bronchial endoscope 5 is inserted into the patient's body, and saline solution is injected into the patient's body through the injection tube 51. The suction tube 521 is connected to an external negative pressure device. By intermittently activating the negative pressure device, the lavage fluid from the patient's lungs is drawn out through the bronchial endoscope 5 and then guided to the inside of the drainage tube 22 through the return tube 52. The drainage tube 22 guides the lavage fluid into the reservoir 3 for storage. When the reservoir 3 is full of lavage fluid, the lifting plate 223 is raised by grasping the handle 224. The lifting block 222 moves upward, and the lifting ring 221 moves upward, compressing the second spring 225, causing the liquid guide tube 22 to move upward and disengage from the inside of the liquid inlet pipe 31. Then, the handle 224 pulls the moving cylinder 21 to move inside the moving groove 11, so that the liquid guide tube 22 moves to the top surface of the liquid inlet pipe 31 of another liquid storage tank 3. Under the action of the rebound force of the second spring 225, the liquid guide tube 22 moves downward and inserts into the inside of the liquid inlet pipe 31, completing the replacement of the liquid storage tank 3. By repeating the operation, the liquid storage tank 3 can be continuously replaced.

[0033] After the flushing fluid is extracted, the stabilizing plate 4 is pressed down, and the stabilizing plate 4 moves down, causing the connecting block 42 to move down. The connecting block 42 then moves the connecting rod 133 down, stretching the first spring 132. The stabilizing plate 4 can then be moved to a lower position on the outside of the storage tank 3. Then the storage tank 3 can be moved up, so that the storage tank 3 is moved out of the placement slot 12 and the inside of the through hole 41. Then the storage tank 3 can be moved to one side, so that the storage tank 3 can be taken out from the inside of the storage frame 1.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
