Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a disposable suction device for fiberoptic bronchoscopes. Background Technology

[0002] Fiberoptic bronchoscopy for sputum suction is a key method for treating respiratory diseases, playing an irreplaceable role, especially in obtaining accurate etiological evidence. The process of using a fiberoptic bronchoscope to deeply aspirate sputum and culture bronchoalveolar lavage fluid is the main method for obtaining deep pathogens in clinical practice. This process is crucial for determining the specific type of infection in patients and guiding subsequent treatment strategies.

[0003] In the complex process of bronchoscopic sputum suction, the specimen container and suction tubing share the same output path. This means that when medical staff use the suction device to alternately aspirate sputum specimens and continue to clear the patient's lungs, subsequent sputum will inevitably flow into the specimen container that already contains the specimen, resulting in specimen contamination. This contamination may weaken the effectiveness of the sputum specimen, making it unable to accurately reflect the patient's lung infection status, and thus adversely affecting subsequent etiological testing and treatment planning. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a disposable sputum suction device for fiberoptic bronchoscope. Through the setting of the alternating mechanism, it can ensure the complete isolation and collection of sputum specimens, and also ensure that after the sputum specimen is suctioned, when the patient continues to clear sputum, the subsequent sputum will not flow into the specimen container that already contains the specimen.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a disposable sputum suction device for fiberoptic bronchoscope, including a specimen tube, the top of which is movably snapped with a sealing cap, and the top of the sealing cap is fixedly provided with an alternating mechanism for switching the sputum output path;

[0006] The alternation mechanism includes a first passage tube, which is fixedly installed on the top left side of the sealing cover. A second passage tube is fixedly installed on the top right side of the sealing cover. A bronchoscope end tee is detachably connected to the end of the first passage tube away from the sealing cover. A negative pressure end tee is detachably connected to the end of the second passage tube away from the sealing cover. A straight tube is detachably connected to the end of the bronchoscope end tee near the negative pressure end tee. The end of the straight tube away from the bronchoscope end tee is detachably connected to the end of the negative pressure end tee near the bronchoscope end tee. A first connecting tube is detachably connected to the end of the bronchoscope end tee away from the straight tube. A second connecting tube is detachably connected to the end of the negative pressure end tee away from the straight tube.

[0007] As a preferred embodiment of this utility model, the first connecting tube is detachably connected to a first expansion tube at the end away from the bronchoscope end tee, and the second connecting tube is detachably connected to a second expansion tube at the end away from the negative pressure end tee.

[0008] As a preferred embodiment of this utility model, the bottom end of the second passage tube penetrates the top inner wall of the sealing cap and extends into the sealing cap.

[0009] As a preferred embodiment of this utility model, a sealing rubber gasket is fixedly installed on the inner wall of the outer side of the sealing cover.

[0010] Compared with the prior art, the beneficial effects of this invention are as follows: by using an alternating mechanism, the suction of sputum specimens and the clearing of sputum from the patient are on different output paths, which can ensure the complete isolation and collection of sputum specimens. It also ensures that after suctioning sputum specimens, when clearing sputum from the patient, subsequent sputum will not flow into the specimen container that already contains specimens, thereby avoiding specimen contamination. This uncontaminated state ensures the validity of sputum specimens, enabling them to truly and accurately reflect the patient's lung infection status, and thus have a positive and accurate impact on subsequent etiological detection and treatment plan formulation.

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0016] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a disposable sputum suction device for fiberoptic bronchoscope, including a specimen tube 1, a sealing cap 2 that is movably snapped onto the top of the specimen tube 1, and an alternating mechanism for switching the sputum output path that is fixedly provided on the top of the sealing cap 2.

[0017] The alternation mechanism includes a first passage tube 21, which is fixedly installed on the top left side of the sealing cover 2. A second passage tube 22 is fixedly installed on the top right side of the sealing cover 2. A bronchoscope end tee 3 is detachably connected to the end of the first passage tube 21 away from the sealing cover 2. A negative pressure end tee 31 is detachably connected to the end of the second passage tube 22 away from the sealing cover 2. A straight tube 4 is detachably connected to the end of the bronchoscope end tee 3 near the negative pressure end tee 31. The end of the straight tube 4 away from the bronchoscope end tee 3 is detachably connected to the end of the negative pressure end tee 31 near the bronchoscope end tee 3. A first connecting tube 5 is detachably connected to the end of the bronchoscope end tee 3 away from the straight tube 4. A second connecting tube 51 is detachably connected to the end of the negative pressure end tee 31 away from the straight tube 4.

[0018] In this case, the left end of the first expansion tube 6 is connected to the bronchoscope, and the right end of the second expansion tube 61 is connected to the negative pressure device. Aseptic procedures are followed during sputum suction and pathogen collection. Under normal circumstances, when medical staff need to suction and clear sputum from a patient, they turn the valves on the bronchoscope end 3 and the negative pressure end 31 to connect the first connecting tube 5, the straight tube 4, and the second connecting tube 51. The negative pressure device then completes sputum suction and clearing through the straight tube 4 and the first expansion tube 6. When pathogen specimens need to be collected, the valves on the bronchoscope end 3 and the negative pressure end 31 are turned to connect the first connecting tube 5, the first access tube 21, the second access tube 22, and the second connecting tube 51. The straight tube 4 is then closed. The negative pressure device, through the cooperation of the first access tube 21 and the second access tube 22, draws sputum into the specimen tube 1. When the pathogen specimen needs to be removed, the first access tube 61 is disconnected from the bronchoscope end 3. The second access tube 22 is pulled out from the negative pressure end tee 31, and the sealing cap 2 is released from the specimen tube 1. This prevents the sputum remaining in the first access tube 21 and the second access tube 22 from contaminating the specimen during the next collection of pathogen specimens. By switching the straight tube 4 and the first access tube 21 through the bronchoscope end tee 3 and the negative pressure end tee 31, the alternating mechanism ensures that sputum specimen collection and sputum clearance for the patient are on different output paths. This ensures complete isolation and collection of sputum specimens and also ensures that after sputum specimen collection, subsequent sputum clearance for the patient will not flow into the specimen tube containing the specimen, thus avoiding specimen contamination. This uncontaminated state ensures the validity of the sputum specimen, enabling it to truly and accurately reflect the patient's lung infection status, thereby having a positive and accurate impact on subsequent pathogen detection and treatment planning.

[0019] The first connecting tube 5 has a first expansion tube 6 detachably inserted at one end away from the tee 3 at the bronchoscope end, and the second connecting tube 51 has a second expansion tube 61 detachably inserted at one end away from the negative pressure end tee 31.

[0020] The left end of the first expansion tube 6 is connected to a bronchoscope, and the right end of the second expansion tube 61 is connected to a negative pressure device, which facilitates the use of the suction device.

[0021] The bottom end of the second passage tube 22 penetrates the top inner wall of the sealing cover 2 and extends into the sealing cover 2.

[0022] The height difference between the bottom of the second access tube 22 and the bottom of the first access tube 21 prevents sputum aspirated from the specimen tube 1 by the first access tube 21 from entering the second access tube 22.

[0023] A sealing rubber gasket is fixedly installed on the inner wall of the outer side of the sealing cover 2.

[0024] The sealing rubber gasket on the inner wall of the sealing cap 2 increases the sealing performance when the sealing cap 2 and the specimen tube 1 are connected.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
