DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 6 The present invention provides a novel leak-proof portable alveolar lavage fluid collection device, comprising a collection bracket and a placement bracket, wherein a plurality of collection tubes 1 are inserted and installed on the collection bracket, a tube cap 2 is threadedly installed on the collection tube 1, a cannula 3 is penetrated through the tube cap 2, and the cannula 3 is integrally formed inside the tube cap 2, a sealing plug 4 with a through hole 5 in the middle is fixedly sleeved at the lower end of the cannula 3, the diameter of the through hole 5 is smaller than the inner diameter of the cannula 3, a sealing component is arranged below the sealing plug 4, and the sealing component comprises a fixing plate 6 and a cover plate 7, the fixed plate 6 is connected to the tube cap 2, a torsion spring 8 is installed on the fixed plate 6, the cover plate 7 is hinged at the bottom of the fixed plate 6 and connected to the torsion spring 8, the torsion spring 8 can make the sealing cover of the cover plate 7 be arranged on the sealing plug 4, the placement bracket is located below the collection bracket, an irrigation bracket is installed on the placement bracket and slides laterally along the placement bracket, the irrigation bracket is located above the collection tube 1, and a tube hole is penetrated through the top surface of the irrigation bracket, and the position of the tube hole corresponds to the position of the insertion tube 3.

[0034] In the process of bronchoalveolar lavage, the working principle and use process of the present invention for collecting bronchoalveolar lavage fluid are as follows:

[0035] First, medical staff need to check the sealing assembly of the collection tube 1 used to ensure that it is in normal condition, that is, the cover plate 7 can be tightly covered on the sealing plug 4 to ensure the sealing performance of the collection tube 1. Then, insert the checked collection tubes 1 one by one into the collection bracket (the collection bracket used here can install four collection tubes 1 at the same time, and it is fully inserted in this operation). After that, install the entire collection bracket on the placement bracket, and slide the irrigation bracket to the top of the first collection tube 1. Next, pass the pipe used to extract the irrigation fluid through the tube hole and the cannula 3 in turn, and continue to insert and push the cover plate 7 to rotate, so that the pipe extends into the collection tube 1, so that the irrigation fluid can be extracted, and the irrigation fluid is introduced into the collection tube 1 for storage. When the medical staff needs to perform group sampling, the medical staff can stop extracting the irrigating fluid, and collect another group of irrigating fluid by pulling out the pipe from the first collection tube 1, then sliding the irrigating bracket to the top of the second collection tube 1, and inserting the pipe into the second collection tube 1 in the same way, and so on, until all the collection tubes 1 on the collection bracket have completed the collection task of the irrigating fluid. Of course, if the irrigating process has not yet ended, the medical staff can replace the next group of collection brackets with collection tubes 1 installed to continue the collection of irrigating fluid. This design ensures the continuity and efficiency of the irrigating fluid collection process, greatly facilitates the collection of samples by medical staff, and provides strong support for the treatment of patients. It is worth mentioning that under the action of the torsion spring 8, the cover plate 7 is gradually reset in the process of pulling out the pipe from the collection tube 1. At the moment when the pipe is pulled out, the cover plate 7 is re-covered on the sealing plug 4, thereby effectively blocking the cannula 3 and restoring the collection tube 1 to a sealed state. Compared with the collection device in the prior art, the present invention simplifies the replacement steps, reduces the replacement time, and improves the replacement efficiency by directly pulling out the pipe from the previous collection tube 1, moving and quickly inserting it into the next collection tube 1. At the same time, at the moment the pipe is pulled out, the cover plate 7 is reset and tightly covered on the sealing plug 4, ensuring the sealing of the collection tube 1, which can not only avoid leakage of the irrigation fluid, but also prevent external air or impurities from entering the collection tube 1, thereby reducing the risk of contamination of the irrigation fluid, ensuring the accuracy of the test results, and providing a solid guarantee for the accurate diagnosis of the disease. In addition, the collection tube 1 is supported and neatly stored by the collection bracket, which not only improves the safety and recognition of the collection tube 1, but also greatly facilitates the carrying and storage of the device, bringing great convenience to the actual work of medical staff.

[0036] In a specific embodiment, see Figure 1 A liquid collecting tube 9 that can be inserted into the cannula 3 is inserted into the tube hole, the other end of the liquid collecting tube 9 is connected to a three-lumen tube 10, the upper end of the three-lumen tube 10 is connected to a syringe 11, and the right end of the three-lumen tube 10 is connected to an irrigation tube 37.

[0037] The pipeline for extracting the irrigating fluid is mainly composed of an irrigating tube 37 and a collecting tube 9, which are connected by a three-lumen tube 10, and a syringe 11 is used as a negative pressure device to extract the irrigating fluid. When extracting the irrigating fluid, the medical staff uses the syringe 11 to generate negative pressure to extract the irrigating fluid, and the irrigating fluid passes through the irrigating tube 37 and the collecting tube 9 in turn, and then flows into the collecting tube 1 for collection. The entire operation process is simple and convenient, which not only reduces the difficulty of operation for medical staff, but also has low investment costs, effectively controls medical costs, and is conducive to promotion.

[0038] In a specific embodiment, see Figure 2 The placement bracket includes a bottom plate 12 and side plates 13 installed on both sides of the bottom plate 12. The side plates 13 are installed above the bottom plate 12 through multiple support rods 14. The collecting bracket is located between the two side plates 13. Both side plates 13 are provided with slide rails. The irrigation bracket includes a top plate 15 and support legs connected to both sides of the top plate 15. The tube hole is opened in the middle of the top plate 15. The two support legs are slidably installed in the slide rails on both sides.

[0039] When the collecting bracket is installed between the two side plates 13 of the bracket, the top plate 15 is slidably installed in the slide rails on the side plates 13 through the supporting legs, which not only ensures that the lavage bracket can move smoothly along the slide rails, but also enables medical staff to easily position the lavage bracket above any collection tube 1, thereby improving the convenience and flexibility of operation, saving time for replacing the collection container during bronchoalveolar lavage, reducing patient testing time, and improving overall surgical efficiency.

[0040] In a specific embodiment, see Figure 1 , Figure 2 and Figure 4 The slide rail includes a horizontal slide groove 16 and a vertical positioning groove 17. The vertical positioning grooves 17 are connected and arranged at equal intervals below the horizontal slide groove 16. The supporting leg includes a square frame 18 and a vertical rod 19. The two short sides of the square frame 18 are respectively clamped in the adjacent vertical positioning grooves 17. The two long sides of the square frame 18 are respectively attached to the two sides of the side plate 13. One end of the vertical rod 19 is connected to the square frame 18, and the other end is connected to the bottom surface of the top plate 15.

[0041] The design structure of the slide rail and the support leg is simple and easy to operate, which provides a strong guarantee for the movement and precise positioning of the irrigation bracket. Specifically, the slide rail is composed of a horizontal slide groove 16 and a vertical positioning groove 17, and the support leg is composed of a square frame 18 and a vertical rod 19. The square frame 18 is clamped in the adjacent vertical positioning groove 17, which can not only limit the position of the irrigation bracket, so that the irrigation bracket can accurately stay directly above the collection tube 1, ensuring that the collection tube 9 inserted on the irrigation bracket can match the position of the insertion tube 3 on the tube cap 2, but also enhance the stability of the irrigation bracket during operation, effectively avoid the occurrence of shaking or tilting, and ensure the smoothness of the irrigation process. When it is necessary to move the group sampling, by lifting the irrigation bracket upward, the square frame 18 slides along the vertical positioning groove 17 to the horizontal slide groove 16, and at this time, the irrigation bracket can move freely in the horizontal direction. When the irrigation bracket moves to the position just above the target collection tube 1, the irrigation bracket is lowered so that the frame 18 is inserted into the vertical positioning groove 17 at other positions, achieving precise fixed-point positioning, laying a solid foundation for subsequent irrigation operations.

[0042] In a specific embodiment, see Figure 4 The top surface of the top plate 15 is provided with a clamping assembly, and the clamping assembly includes a clamping plate 20, a clamping ring 21 and a tightening bolt 22. The clamping plate 20 and the clamping ring 21 are respectively located on both sides of the pipe hole. The clamping plate 20 is fixedly connected to the top plate 15, and the clamping ring 21 is installed on the clamping plate 20 through the tightening bolt 22.

[0043] By setting a clamping assembly on the top surface of the top plate 15, the clamping assembly ensures that the collection tube 9 can be stably installed on the top plate 15 through the coordinated cooperation of the clamping plate 20, the clamping ring 21 and the tightening bolt 22, thereby preventing the collection tube from being pulled and falling off during the extraction of the irrigation fluid, thereby effectively preventing the leakage or waste of the irrigation fluid and the possible risk of contamination, ensuring the stability of the irrigation process, and ensuring the smooth extraction and collection of the irrigation fluid.

[0044] In a specific embodiment, see Figure 4 A hose 23 is provided on the top surface of the top plate 15 . The hose 23 is located between the clamping plate 20 and the clamping ring 21 . The hose 23 is located outside the pipe hole and is fixedly connected to the top plate 15 .

[0045] The hose 23 is located on the outside of the collecting pipe 9. When the collecting pipe 9 is passed through and fixed by the clamping plate 20, the clamping ring 21 and the tightening bolt 22, the hose 23 and the collecting pipe 9 fit together, achieving a firm clamp while effectively protecting the collecting pipe 9 and avoiding unnecessary damage to the collecting pipe 9 due to excessive clamping.

[0046] In a specific embodiment, see Figure 5A discharge pipe 24 is provided through the pipe cap 2 . The discharge pipe 24 is integrally formed on the top surface of the pipe cap 2 . A sealing cap 25 is threadedly connected to the discharge pipe 24 .

[0047] When taking the lavage fluid for testing, the medical staff only needs to remove the sealing cap 25 from the discharge tube 24, and then appropriately tilt the collection tube 1 to pour the lavage fluid out of the discharge tube 24. After taking, the sealing cap 25 is put back on to quickly restore its sealing state, ensuring that the remaining lavage fluid in the collection tube 1 is not contaminated. This design makes it not only simple and convenient to take the lavage fluid, but also can effectively control the amount of lavage fluid taken, thereby meeting the sample volume requirements of different test items.

[0048] In a specific embodiment, see Figure 3 The collecting bracket includes a base 26, a first vertical plate 27, a second vertical plate 28 and a card plate 29. The two ends of the card plate 29 are respectively installed above the base 26 through the first vertical plate 27 and the second vertical plate 28. The top surface of the base 26 is provided with a plurality of card slots 30, and the card plate 29 is provided with a plurality of card holes 31 corresponding to the positions of the card slots 30.

[0049] The collection bracket is composed of a base 26, a first vertical plate 27, a second vertical plate 28 and a clamping plate 29. The positions of the clamping slot 30 and the clamping hole 31 correspond to each other, which realizes the precise positioning of the collection tube 1, ensures the cooperation between the collection tube 1 and the irrigation bracket, and provides a strong guarantee for the precise insertion of the liquid collection tube 9. Moreover, after the collection tube 1 is inserted from the clamping hole 31, its lower end enters the clamping slot 30, which effectively ensures the stability of the collection tube 1 inserted and installed on the collection bracket, effectively prevents the collection tube 1 from falling off or shifting due to shaking or external force, and ensures the smooth progress of the irrigation process.

[0050] In a specific embodiment, see Figure 1 The collecting bracket also includes a limit block 32, which is connected to the first vertical plate 27 on one side, and the end of the limit block 32 abuts against the end of the placement bracket.

[0051] When the collecting bracket is installed on the placing bracket, the limiting block 32 abuts against the end of the placing bracket, which serves as an installation reference point, ensuring that the collecting bracket is installed at a predetermined position, thereby improving the use efficiency.

[0052] In a specific embodiment, see Figure 6The first vertical plate 27 is staggered with a first lock buckle 33 and a second lock buckle 34, and the second vertical plate 28 is staggered with a first lock tongue 35 and a second lock tongue 36. The adjacent collecting brackets can be arranged in a staggered combination, wherein the first lock buckle 33 cooperates with the first lock tongue 35 on the adjacent collecting bracket, and the second lock buckle 34 cooperates with the second lock tongue 36 on the adjacent collecting bracket.

[0053] When carrying multiple collection brackets, these collection brackets can be combined and connected in a staggered arrangement to form a stable overall structure. Specifically, the first lock buckle 33 on the first vertical plate 27 is engaged with the first lock tongue 35 on the second vertical plate 28 on the right collection bracket, and at the same time, the second lock buckle 34 on the first vertical plate 27 is engaged with the second lock tongue 36 on the second vertical plate 28 on the left collection bracket. This combination mechanism can connect multiple collection brackets together, improve their stability, and make the entire structure more convenient, easy, safe and efficient when carrying, transporting or storing.

[0054] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
