Description

Technical Field

[0001] This utility model relates to the field of bronchoscopy irrigation and collection technology, specifically to a bronchoscopy irrigation fluid collection device. Background Technology

[0002] Fiberoptic bronchoalveolar lavage is a commonly used diagnostic and treatment method in respiratory diseases, playing a particularly important role in the treatment of patients with severe pneumonia complicated by respiratory failure. This technique uses a fiberoptic bronchoscope catheter to directly remove airway secretions under direct vision, rapidly alleviating ventilatory dysfunction in patients. Lower respiratory tract secretion specimens are also collected for microbial culture and drug sensitivity testing, providing experimental results for precise anti-infective treatment.

[0003] like Figure 4 The diagram shown is a cross-sectional view of a prior art bronchoscopic lavage fluid collection device. The top cover 2' of the collection bottle 1' is connected to a suction tube 5' and a suction tube 6' via a suction port 3' and a suction port 4', respectively. Connecting caps A7' and B9' are respectively installed at the ends of the suction tube 5' and suction tube 6'. Additionally, an inlet 8' connecting to the suction port 3' is located on the inner top wall of the top cover. Its working principle is that the entire bronchoscopic lavage fluid collection device is considered as a suction pipe. By connecting caps A7' and B9' to the outlet end of the bronchoscope and the input end of the suction device, respectively, the suction device generates suction, causing the suction force to pass through the bronchoscope tube, the outlet end of the bronchoscope, and the suction pipe, and exit from the output end of the suction device. The patient's lung secretions are stored in the collection bottle 1'.

[0004] However, existing fiberoptic bronchoalveolar lavage fluid collection devices have a significant technical drawback: the inlet 8' is typically a straight tube. When used with gas, the pressure impact easily causes foam to accumulate in the collection bottle. This foam buildup creates a space obstruction within the bottle, preventing it from holding more lavage fluid before it is full; it is expected to hold only about one-third of its capacity. This indirectly requires repeated procedures by healthcare personnel, necessitating multiple lavage sessions for the patient, increasing surgical time. Furthermore, the increased volume of lavage fluid used leads to greater patient discomfort, and the longer the lavage fluid remains in the lungs, the higher the risk of complications. Utility Model Content

[0005] This invention proposes a bronchoscopy irrigation fluid collection device, which solves the problem in the prior art where the bronchoscopy irrigation fluid collection bottle is difficult to hold due to the formation of foam accumulation caused by gas impact, creating a spatial obstacle.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A fiberoptic bronchoscopy irrigation fluid collection device includes a collection bottle with a top cap and a suction tube head on the top of the top cap.

[0008] The bottom of the top cap is provided with an inlet pipe corresponding to the suction tube head, and the inlet pipe has a guiding structure to guide the rinsing liquid toward the inner wall of the collection bottle.

[0009] Furthermore, the inlet pipe is either an integrated pipe or a detachable pipe.

[0010] Furthermore, the guiding structure is a guide tube integrally formed with the liquid inlet pipe and at a certain angle to it. The guide tube is connected to the liquid inlet pipe and faces the inner wall of the collection bottle.

[0011] Furthermore, the angle of the guide tube is between 30° and 90°.

[0012] Furthermore, the guiding structure is a guide hole provided on the side of the inlet pipe, with the guide hole facing the inner wall of the collection bottle; and the bottom of the inlet pipe is closed.

[0013] Furthermore, the top of the top cover is also provided with a negative pressure pipe head, and a negative pressure hose is connected to the negative pressure pipe head.

[0014] Furthermore, a suction tube is fitted onto the suction tube head.

[0015] Furthermore, a bronchoscope connector cap is connected to the end of the suction tubing.

[0016] Furthermore, the bottom of the collection bottle is provided with a bottom seal.

[0017] The beneficial effects of the technical solution provided in this application are as follows:

[0018] 1. This fiberoptic bronchoscopy irrigation fluid collection device, by designing a guiding structure on the inlet pipe with the side of the guiding structure away from the top cap facing the inner wall of the collection bottle, is expected to effectively reduce the problem of foam accumulation in the collection bottle due to gas impact. This design reduces the space occupied by foam in the collection bottle, allowing the collection bottle to hold more irrigation fluid and improving collection efficiency. It avoids premature overflow of the collection bottle due to foam accumulation, thus ensuring the continuity and integrity of the irrigation process.

[0019] 2. The improved guide structure of this fiberoptic bronchoscopy irrigation fluid collection device allows the collection bottle to be filled with irrigation fluid, enabling the irrigation procedure to be completed in one session. This reduces patient discomfort, minimizes complications, shortens surgical time, and improves work efficiency. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] Reference Figure 1-2A bronchoscopic irrigation fluid collection device includes a collection bottle 10, a top cap 11 on top of the collection bottle 10, a suction tube head 13 and a negative pressure tube head 14 on the top of the top cap 11; and an inlet tube 17 corresponding to the suction tube head 13 at the bottom of the top cap 11. The inlet tube 17 has a guiding structure to guide the irrigation fluid towards the inner wall of the collection bottle 10. The collection bottle 10, as the main collection container for the irrigation fluid, should be designed to hold a sufficient volume of irrigation fluid and facilitate cleaning and disinfection. The top cap 11, located at the top of the collection bottle, should be designed to ensure a tight seal to prevent leakage of the irrigation fluid; it is typically connected to the collection bottle 10 via a threaded connection for easy installation and disassembly. The suction tube head 13 is mainly used to connect the guiding tube for the irrigation fluid, providing basic support and facilitating the introduction of the irrigation fluid into the collection bottle 10. The inlet tube 17 extends downwards to minimize foam generation and reduce the likelihood of foam formation. By incorporating a guiding structure in the inlet tube 17, the lavage fluid is sprayed towards the inner wall of the collection bottle 10. The inner wall cushions the impact, reducing foam formation, improving collection efficiency, preventing premature overflow, ensuring continuous and complete lavage, reducing the frequency of operation for medical staff, and alleviating patient discomfort and the risk of complications. The fiberoptic bronchoalveolar lavage fluid collection device is considered a suction conduit. The suction head 13 and the negative pressure head 14 are connected to the fiberoptic bronchoscope outlet tube and the suction inlet, respectively. The suction device generates suction, drawing fluid from the patient's lungs through the fiberoptic bronchoscope tube, outlet tube, and suction conduit to the suction outlet. Secretions and tissues are stored in the collection bottle 10. The guiding structure alters the flow direction of the lavage fluid, causing it to disperse and flow down the inner wall of the collection bottle 10, reducing gas intrusion, decreasing foam formation, and increasing the capacity and collection efficiency of the collection bottle 10.

[0029] In some embodiments, the inlet tube 17 is either an integrated tube or a detachable tube. Regardless of whether it is an integrated or detachable tube, the main function of the inlet tube 17 is to guide the irrigation fluid from the suction head 13 into the collection bottle 10 during the bronchoscope irrigation process. An integrated tube ensures a tight seal during irrigation through its robust connection, while a detachable tube improves the cleaning and maintenance efficiency of the device through its easy separation. During irrigation, the irrigation fluid is drawn in through the suction hose 15 and then enters the collection bottle 10 through the inlet tube 17. The curved design of the inlet tube helps the irrigation fluid flow along the inner wall of the collection bottle, reducing foam formation and improving collection efficiency. The integrated or detachable design further enhances the practicality and ease of maintenance of the device, ensuring long-term stable operation.

[0030] The top of the top cap 11 is also equipped with a negative pressure tube head 14, to which a negative pressure hose 16 is connected. The negative pressure tube head 14, through the connection to the negative pressure hose 16, provides the necessary negative pressure for the bronchoscopic irrigation process, facilitating the aspiration of the patient's respiratory secretions into the collection bottle 10. The introduction of negative pressure accelerates the inflow rate of the irrigation fluid, improves collection efficiency, and ensures a rapid and effective irrigation process. The design of the negative pressure tube head 14 makes connecting and disconnecting the negative pressure hose 16 easier, facilitating operation and maintenance when needed. During bronchoscopic irrigation, the negative pressure tube head 14, through the suction cap 19 set in the negative pressure hose 16, is connected to an external negative pressure source to generate negative pressure. This negative pressure helps the suction tube head 13 aspirate the patient's respiratory secretions, which then enter the collection bottle 10 through the inlet tube 17. The continuous negative pressure ensures that the irrigation fluid can be effectively extracted and collected from the patient's body. At the same time, the curved design of the inlet tube 17 helps guide the irrigation fluid to flow along the inner wall of the collection bottle, reducing foam formation and further improving collection efficiency and stability.

[0031] A suction tube 15 is fitted onto the suction head 13. The suction tube 15 makes the entire device more flexible during operation, facilitating adjustments to the position and angle of the suction head 13 as needed. The design of the suction tube 15 allows for quick connection and disconnection from the suction head 13, making it convenient for operators to replace or clean it when necessary. During bronchoscope irrigation, the suction tube 15 is connected to the suction head 13, forming a channel from the patient's airway to the collection bottle 10. Negative pressure is transmitted to the suction head 13 through the negative pressure head 14 and negative pressure tube 16, generating suction to draw the patient's respiratory secretions into the suction tube 15 and ultimately into the collection bottle 10. The flexibility of the suction tube 15 allows the operator to adjust the position of the suction head 13 without disturbing the patient, for more effective collection of irrigation fluid. Simultaneously, the detachable nature of the suction tube 15 allows for easy cleaning and disinfection after the irrigation process, for future use.

[0032] The end of the suction tubing 15 is connected to a bronchoscope connector cap 18. The design of the bronchoscope connector cap 18 ensures a sealed connection between the suction tubing 15 and the bronchoscope, preventing leakage during irrigation. The connector cap 18 provides a convenient operating interface, allowing the suction tubing 15 to be quickly and stably connected to the bronchoscope, facilitating operation by medical personnel. During bronchoscope irrigation, the suction tubing 15 is tightly connected to the bronchoscope via the bronchoscope connector cap 18, forming a closed suction channel. The bronchoscope connector cap 18 ensures the stability of the connection between the suction tubing 15 and the bronchoscope.

[0033] The collection bottle 10 has a bottom seal 12. The bottom seal 12 ensures the bottom of the collection bottle 10 is completely sealed, preventing leakage of the irrigation fluid and maintaining hygiene and safety during the collection process. During bronchoscope irrigation, the bottom seal 12 tightly seals the bottom of the collection bottle 10, ensuring the airtightness of the entire collection system. After irrigation, the bottom seal 12 can be removed to safely drain the collected irrigation fluid from the collection bottle 10, facilitating cleaning and disinfection of the collection bottle for future use. The presence of the bottom seal 12 improves the practicality and safety of the entire collection device, ensuring that hygiene standards for the medical process are met.

[0034] In some embodiments, the guiding structure is a guide tube 17a integrally formed with the inlet pipe 17 and at a certain angle to it. The guide tube 17a communicates with the inlet pipe 17 and faces the inner wall of the collection bottle 10. When the guiding structure is a guide tube 17a integrally formed with the inlet pipe 17 and at a certain angle to it, its function and effect are to change the flow direction of the irrigation fluid, causing it to spray towards the inner wall of the collection bottle 10, thereby reducing the foam that accumulates in the collection bottle due to gas impact, improving the capacity utilization and collection efficiency of the collection bottle, ensuring the continuity of the irrigation process, reducing the operation frequency of medical staff, and reducing the patient's surgical pain and risk of complications. The guide tube 17a is connected to the inlet tube 17 and faces the inner wall of the collection bottle 10. When the suction device generates suction, the irrigation fluid enters the inlet tube 17 from the outlet end of the fiberoptic bronchoscope through the suction tube 15 and the negative pressure tube 16. Then, the flow direction is changed through the guide tube 17a. After impacting the inner wall of the collection bottle 10, the fluid disperses and flows down, reducing gas incorporation, reducing foam generation, and improving the capacity and collection efficiency of the collection bottle 10.

[0035] The angle of the bend in the tube is between 30° and 90°. This angle helps control the flow direction of the rinsing fluid into the collection bottle 10, allowing it to flow along the bottle wall and reducing direct impact on the bottle bottom, thus minimizing foam formation. During the bronchoscope rinsing process, the rinsing fluid is drawn in through the suction head 13 and the suction hose 15, and then enters the collection bottle 10 through the inlet tube 17 with a specific angle. The bend angle is between 30° and 90°, which allows the rinsing fluid to flow along the inner wall of the collection bottle upon entry, reducing foam formation. This design helps disperse the impact force of the rinsing fluid, allowing it to form a thin film inside the collection bottle instead of directly impacting the bottom and forming foam. In this way, the effective capacity of the collection bottle is increased, ensuring the continuity and integrity of the rinsing process, while also improving the stability and reliability of the collection device.

[0036] Example 2

[0037] The guiding structure is a guide hole 17b located on the side of the inlet tube 17, facing the inner wall of the collection bottle 10; and the bottom of the inlet tube 17 is closed. The function of this guide structure, with the guide hole 17b facing the inner wall of the collection bottle 10, is to allow the irrigation fluid to directly impact the inner wall when sprayed out. The inner wall's buffering effect weakens the impact force of the liquid, thereby reducing gas incorporation and foam generation. Simultaneously, the closed bottom prevents liquid from flowing directly out from the bottom, further controlling the flow path of the liquid within the collection bottle, allowing the liquid to flow more evenly along the inner wall, improving the capacity utilization and collection efficiency of the collection bottle, ensuring the continuity of the irrigation process, reducing the frequency of operation for medical staff, and lowering the patient's surgical pain and risk of complications. When the suction device generates suction, the irrigation fluid enters the inlet tube 17 from the outlet end of the bronchoscope through the suction tube and the aspiration tube, and then is sprayed out through the guide hole 17b on the side. Since the guide hole 17b faces the inner wall of the collection bottle 10, the irrigation fluid disperses and flows down after impacting the inner wall. The closed bottom prevents the liquid from continuing to flow downward, so that the liquid is evenly distributed along the inner wall in the collection bottle, reducing gas incorporation and foam formation, and improving the capacity and collection efficiency of the collection bottle.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
