Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an alveolar lavage device. Background Technology

[0002] Bronchoalveolar lavage is a non-invasive procedure performed via bronchoscopy. A catheter is inserted through the nasal cavity or mouth. When the catheter reaches the diseased bronchus, fluid is injected through the catheter and aspirated to collect the fluid on the surface of the alveoli and remove the substances filling the alveoli. This allows for the examination of inflammation, immune cells, and soluble substances, achieving the goal of accurate diagnosis and treatment. It has been widely accepted in disease diagnosis.

[0003] Existing irrigation devices have limited functionality, only capable of performing irrigation or liquid extraction, making operation cumbersome and resulting in low irrigation efficiency. Utility Model Content

[0004] In order to address the problems of existing lavage devices having limited functionality, only capable of performing lavage or fluid extraction, and being cumbersome to operate with low lavage efficiency, this application provides an alveolar lavage device.

[0005] The bronchoalveolar lavage device provided in this application adopts the following technical solution: A bronchoalveolar lavage device includes a storage tank and an lavage tube. A suction tube and a suction tube are connected to the top of the storage tank. The suction tube is connected to the lavage tube through a regulating valve. The regulating valve includes a valve seat. A first connector, a second connector, a third connector, and a fourth connector are respectively provided on the side of the valve seat. The suction tube is connected to the first connector. A rotatable valve core is provided inside the valve seat. By rotating the valve core, the regulating valve can be adjusted so that any three connectors on the side of the valve seat are interconnected or the four connectors are interconnected in pairs. The lavage tube includes an outer tube and an inner tube. The outer tube is connected to the third connector, and the inner tube is connected to the second connector.

[0006] By adopting the above technical solution, when using the alveolar lavage device, the lavage fluid syringe is connected to the fourth connector on the side of the regulating valve. By rotating the valve core inside the regulating valve, the fourth connector can be connected to the third connector, and the first connector can be connected to the second connector. Thus, the syringe is connected to the outer tube, through which lavage fluid is injected into the alveoli. The inner tube is connected to the suction tube, and the lavage fluid is extracted through the inner tube and the suction tube at the same time as lavage, realizing the simultaneous lavage and extraction, thus improving the lavage efficiency. At the same time, by rotating the regulating valve, the fourth connector can also be connected to the second and third connectors, or the first connector can be connected to the second and third connectors, so that the inner and outer tubes can be used simultaneously for injecting or extracting lavage fluid, thus expanding the functionality of the lavage device.

[0007] Optionally, a first valve core is rotatably disposed inside the valve seat. The side of the first valve core is provided with through holes corresponding to the first connector, the second connector, the third connector and the fourth connector, respectively.

At this time, the other three through holes on the side of the first valve core are connected through the through groove. The first valve core and the valve seat cooperate to form a three-way valve. By rotating the valve core, it can be adjusted to connect three of the first connector, second connector, third connector and fourth connector. At the same time, rotating the second valve core causes the two ends of the connecting hole in the stop block on the second valve core to connect to the two through holes on the side of the first valve core respectively, so that the four through holes on the side of the first valve core are connected in pairs. Rotating the first valve core can connect the first connector, second connector, third connector and fourth connector in pairs to meet different usage requirements.

[0016] By adopting the above technical solution, the irrigation tube is equipped with an independent first delivery chamber and a second delivery chamber. During irrigation, the irrigation fluid can be delivered through the first delivery chamber between the outer tube and the inner tube and then delivered to the alveoli for cleaning through the second delivery hole. After cleaning, the irrigation fluid can be extracted through the first delivery hole on the plug into the second delivery chamber in the inner tube, thereby realizing the simultaneous injection and extraction of fluid and improving the efficiency of irrigation.

[0017] Optionally, the outer tube and the inner tube are connected to a connector at their ends, and a first connecting pipe communicating with the first conveying cavity and a second connecting pipe communicating with the second conveying cavity are provided on one side of the connector.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] This embodiment discloses an alveolar lavage device.

[0035] Reference Figure 1A bronchoalveolar lavage device includes a storage tank 1, a suction pipe 2 and a suction pipe 3 connected to the top of the storage tank 1, a three-way sleeve 4 connected to the end of the suction pipe 3, a negative pressure device connected to the suction pipe 3 through the three-way sleeve 4, and a lavage pipe 2 connected to an irrigation pipe 6 through a regulating valve 5.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The regulating valve 5 includes a valve seat 55. A first connector 51, a second connector 52, a third connector 53, and a fourth connector 54 are circumferentially arranged on the side of the valve seat 55. A first valve core 56 is rotatably mounted inside the valve seat 55. The upper end of the first valve core 56 extends upward to form a rotating handle. Four through holes 561 are provided on the side wall of the first valve core 56 corresponding to the first connector 51, second connector 52, third connector 53, and fourth connector 54. A second valve core 57 is rotatably mounted inside the first valve core 56. The bottom of the second valve core 57 extends downward to form a rotating handle. A valve core 57 is engaged in the middle of the second valve core 57 corresponding to the through holes 561. The through groove 572 is filled with filter cotton. An elliptical cross-section baffle 573 is formed on one side of the through groove 572. An arc-shaped connecting hole 571 is opened on the side of the baffle 573 corresponding to the through hole 561. When the second valve core 57 is rotated, when the baffle 573 blocks one of the through holes 561, the other three through holes 561 are connected through the through groove 572. When the second valve core 57 is rotated to the point where the two ends of the connecting hole 571 on the baffle 573 are connected to two of the through holes 561 respectively, the other two through holes 561 are connected. Thus, by rotating the second valve core 57, the connection of three or two of the four through holes 561 can be adjusted.

[0037] Reference Figure 5 The irrigation tube 6 includes an outer tube 61 and an inner tube 62. The inner tube 62 is disposed inside the outer tube 61, forming a first conveying cavity 64 between the inner tube 62 and the outer tube 61. A second conveying cavity 65 is disposed inside the inner tube 62. A plug 63 is disposed at the end of the outer tube 61. A first conveying hole 66 is opened on the side of the plug 63, and the inner tube 62 is connected to the plug 63. A first conveying hole 66 is opened on the side of the plug 63. A second conveying hole 67 is opened on the side wall of the end of the outer tube 61, which is connected to the first conveying cavity 64. A connector 68 is connected to the ends of the outer tube 61 and the inner tube 62. A first connecting pipe 69 is disposed on one side of the connector 68, which is connected to the first conveying cavity 64, and a second connecting pipe 610 is disposed on one side, which is connected to the second conveying cavity 65.

[0038] The implementation principle of the alveolar lavage device in this embodiment is as follows: During the rinsing operation, the air extraction pipe 3 is connected to the negative pressure device through the three-way sleeve 4, the first connecting pipe 69 in the rinsing pipe 6 is connected to the third connector 53, and the second connecting pipe 610 is connected to the second connector 52. When simultaneous injection and aspiration are required, refer to... Figure 6The syringe 7 is connected to the fourth connector 54. Rotating the second valve core 57 causes the connecting hole 571 on the stop 573 inside the second valve core 57 to connect with the two through holes 561 on the side of the first valve core 56. Then, rotating the first valve core 56 causes the two through holes 561 connected to the connecting hole 571 to connect the first connector 51 and the second connector 52. The third connector 53 and the fourth connector 54 are connected through the through groove 572. At this time, the suction tube 2 is connected to the inner tube 62 of the irrigation tube 6 through the regulating valve 5, and the syringe 7 is connected to the outer tube 61 of the irrigation tube 6 through the regulating valve 5. During irrigation, the irrigation fluid is injected into the first delivery chamber 64 between the outer tube 61 and the inner tube 62 using a syringe 7. The filter cotton inside the through groove 572 filters the irrigation fluid. The irrigation fluid is delivered to the alveoli for rinsing through the first delivery chamber 64 and the second delivery hole 67. At the same time, the negative pressure device creates negative pressure in the storage tank 1 through the suction pipe 3. The suction pipe 2 draws the rinsed irrigation fluid into the storage tank 1 for storage through the second delivery chamber 65 in the middle of the inner tube 62 and the first delivery hole 66 on the plug 63, thereby realizing simultaneous injection and extraction for irrigation. When continuous flushing of the alveoli is required, refer to... Figure 7 Rotating the second valve core 57 causes the stop 573 inside the second valve core 57 to block one of the through holes 561, and the other three through holes 561 are connected through the through groove 572. Then, rotating the first valve core 56 causes the three connected through holes 561 to connect to the second connector 52, the third connector 53 and the fourth connector 54 respectively. At this time, the syringe 7 connects to the first delivery chamber 64 and the second delivery chamber 65 inside the irrigation tube 6 through the regulating valve 5. The irrigation fluid is delivered to the alveoli through the syringe 7, the first delivery chamber 64 and the second delivery chamber 65. The first delivery hole 66 and the second delivery hole 67 at the end of the irrigation tube 6 simultaneously discharge irrigation fluid for flushing, thereby improving the flushing effect. When the flushing solution needs to be removed after rinsing, refer to... Figure 8 Rotating the first valve core 56 causes the three interconnected through holes 561 to connect to the first connector 51, the second connector 52, and the third connector 53 respectively. The suction tube 2 connects to the first delivery chamber 64 and the second delivery chamber 65 inside the irrigation tube 6 through the regulating valve 5. The suction tube 2 extracts the irrigation fluid from the alveoli through the first delivery hole 66, the second delivery hole 67, the first delivery chamber 64, and the second delivery chamber 65, thereby increasing the suction rate and ensuring that the irrigation fluid can be completely extracted.

[0039] In summary, the irrigation tube in this application has independent inner and outer tubes, and the regulating valve has a first valve core and a second valve core. Through the cooperation of the regulating valve and the irrigation tube, the syringe and the suction tube can be connected to the inner and outer tubes respectively, or the syringe can be connected to both the inner and outer tubes simultaneously, or the suction tube can be connected to both the inner and outer tubes simultaneously. This allows the irrigation device to perform multiple irrigation modes, expanding its functionality and improving the efficiency and effectiveness of the irrigation operation. Therefore, this application effectively overcomes the various shortcomings of the prior art and has high industrial application value.
