Description

Technical Field

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

[0002] In biomedical research and clinical treatment, bronchoalveolar lavage (BAL) is a crucial diagnostic and therapeutic tool widely used in the assessment and treatment of lung diseases. This process typically involves injecting a certain amount of lavage fluid into the lungs and collecting the filtered fluid using a novel BAL recovery device for subsequent analysis. The lavage fluid contains abundant cellular components, proteins, metabolites, and various biomarkers, which play a vital role in disease diagnosis, continuous monitoring of the condition, and objective evaluation of treatment effectiveness.

[0003] However, traditional bronchoalveolar lavage fluid (BALF) recovery devices are susceptible to external contamination during the recovery process, especially when using serum containing endotoxins (such as newborn calf serum, fetal bovine serum, or horse serum, which are commonly used culture medium additives). If the device is not properly sealed, endotoxins may contaminate the LF, affecting the accuracy of experimental results and potentially posing risks to patient health. Furthermore, when removing air from the LF recovery device, the sample may be drawn away with the air, resulting in sample loss and further impacting the quality and reliability of subsequent analyses.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the novel bronchoalveolar lavage fluid recovery device according to an embodiment of the present invention includes a recovery tank 1. The top of the recovery tank 1 is respectively provided with a mounting base 1 2 and a mounting base 2 3. The top of the mounting base 1 2 is provided with a bronchoalveolar lavage fluid inlet component 4, and the bronchoalveolar lavage fluid inlet component 4 is fixed to the mounting base 1 2 by a number of sets of bolts 1 5. The bottom of the mounting base 1 2 is provided with an anti-backflow component 6. The top of the mounting base 2 3 is provided with an air extraction component 7, and the air extraction component 7 is fixed to the mounting base 2 3 by a number of sets of bolts 2 8.

[0029] By utilizing the above-mentioned technical solution of this utility model, by setting the anti-backflow component 6, it is possible not only to effectively prevent the collected bronchoalveolar lavage fluid from flowing back into the inlet path or into the patient's body, thereby avoiding the potential risk of cross-contamination, but also to precisely control the volume of bronchoalveolar lavage fluid, thereby improving the accuracy of the sample.

[0030] In one embodiment, for the aforementioned mounting base 2, the mounting base 2 cooperates with the bronchoalveolar lavage fluid inlet assembly 4 through sealing ring 9, and the mounting base 3 cooperates with the air extraction assembly 7 through sealing ring 10, thereby effectively preventing airborne pollutants from entering the device and ensuring that the bronchoalveolar lavage fluid remains sterile throughout the entire collection process.

[0031] In one embodiment, the mounting base 2 includes a mounting ring 201 disposed at the top of the recovery tank 1, and a fixing ring 202 is disposed on the inner wall of the mounting ring 201, thereby realizing the installation of the bronchoalveolar lavage fluid inlet assembly 4 and improving the functionality of the recovery device.

[0032] In one embodiment, the bronchoalveolar lavage fluid inlet assembly 4 includes a connecting ring 401 disposed at the top of the mounting base 2, a bronchoalveolar lavage fluid inlet pipe 402 disposed inside the connecting ring 401, and a filter plate 403 disposed at the bottom end of the bronchoalveolar lavage fluid inlet pipe 402, thereby eliminating air bubbles in the bronchoalveolar lavage fluid and ensuring that the bronchoalveolar lavage fluid entering the recovery tank 1 is free from air bubble interference.

[0033] In one embodiment, the anti-backflow component 6 includes a connecting pipe 601 disposed at the bottom of the mounting base 2. A movable plug 602 is disposed inside the connecting pipe 601, and the movable plug 602 cooperates with the fixing ring 202. A connecting rod 603 is disposed at the bottom of the movable plug 602, and a float 604 is disposed at the bottom of the connecting rod 603. An outlet pipe 605 is disposed on the outer circumference of the connecting pipe 601, thereby effectively preventing the collected bronchoalveolar lavage fluid from flowing back into the inlet path or into the patient's body, avoiding potential cross-contamination risks.

[0034] In one embodiment, the mounting base 3 includes a mounting ring 301 at the top of the recovery tank 1, a connecting pipe 302 at the bottom of the mounting ring 301, a filter plate 303 at the bottom of the connecting pipe 302, and a plurality of filter holes 304 on the outer bottom of the connecting pipe 302, thereby effectively removing moisture from the gas and ensuring the dryness of the gas treatment.

[0035] In one embodiment, the above-mentioned suction assembly 7 includes a connecting ring 701 disposed at the top of the mounting base 3, a suction pipe 702 disposed inside the connecting ring 701, and a filter plate 703 disposed at the bottom of the suction pipe 702, thereby effectively preventing the collected bronchoalveolar lavage fluid from being extracted, ensuring the integrity of the bronchoalveolar lavage fluid and the accuracy of the experimental results.

[0036] The working principle of the anti-backflow component 6 is as follows: After the bronchoalveolar lavage fluid is de-aired, it enters the recovery tank 1 through the outlet pipe 605. When a certain amount of bronchoalveolar lavage fluid flows into the recovery tank 1, the bronchoalveolar lavage fluid level gradually rises and comes into contact with the float 604. As more fluid flows in, the fluid level continues to rise, pushing the float 604 upward. The upward movement of the float 604 causes the movable plug 602 inside the connecting pipe 601 to move upward as well. When the movable plug 602 moves to a certain position, it will cooperate with the fixed ring 202 to form a sealing structure, preventing the bronchoalveolar lavage fluid from flowing back through the bronchoalveolar lavage fluid inlet pipe 402, thereby ensuring that the collected fluid will not flow back into the inlet path.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In practical applications, the bronchoalveolar lavage fluid inlet assembly 4 is installed above the mounting base 2 and secured with bolt 5. The suction assembly 7 is installed above the mounting base 3 and secured with bolt 8. After installation, the bronchoalveolar lavage fluid is introduced into the recovery device through the bronchoalveolar lavage fluid inlet pipe 402. The introduced bronchoalveolar lavage fluid passes through the filter plate 403, which eliminates air bubbles in the bronchoalveolar lavage fluid, ensuring that the bronchoalveolar lavage fluid entering the recovery tank 1 is free from air bubble interference. After degassing, the bronchoalveolar lavage fluid enters the recovery tank 1 via the anti-backflow assembly 6 (the working principle of the anti-backflow assembly 6 is as described above). When air is drawn through the suction pipe 702, the gas passes through the combined action of filter plate 303, filter hole 304, and filter plate 703, effectively removing moisture from the gas. In addition, the filter plate 703 and filter hole 304 prevent the collected bronchoalveolar lavage fluid from being drawn out along with the air during the suction process, thereby ensuring the volume and purity of the bronchoalveolar lavage fluid.

[0039] In summary, by utilizing the above-mentioned technical solution of this utility model, the anti-backflow component 6 effectively prevents the collected bronchoalveolar lavage fluid from flowing back into the inlet path or into the patient's body, thus avoiding potential cross-contamination risks. It also precisely controls the volume of the bronchoalveolar lavage fluid, thereby improving sample accuracy. By setting sealing ring 9 and sealing ring 10, airborne contaminants are effectively prevented from entering the device, ensuring the bronchoalveolar lavage fluid remains sterile throughout the collection process. This not only prevents contamination of experimental results and protects the health and safety of patients but also ensures the purity of the bronchoalveolar lavage fluid. Through the synergistic effect of filter plate 303, filter holes 304, and filter plate 703, moisture in the gas is effectively removed, ensuring the dryness of the gas treatment. Furthermore, the cooperation between filter plate 703 and filter holes 304 effectively prevents the collected bronchoalveolar lavage fluid from being extracted during the evacuation process, thus ensuring the integrity of the bronchoalveolar lavage fluid and the accuracy of the experimental results.
