Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a bronchoscope irrigation device. Background Technology

[0002] A fiberoptic bronchoscope, or bronchoscope for short, is a widely used medical device in clinical practice. During use, the bronchoscope is inserted through the patient's mouth and nose to directly observe lesions in the trachea, lungs, and other areas, enabling various diagnostic and therapeutic procedures for respiratory diseases. However, when the observed area is covered with thick secretions or mucus, it can severely impair the doctor's field of vision, thus affecting the accuracy of diagnosis and treatment. Therefore, it is necessary to flush the bronchoscope promptly to remove these deposits and restore a clear view.

[0003] The traditional manual flushing method involves the nurse using a syringe to draw 10-20 ml of saline solution from a saline bottle and quickly injecting it through the side port of a bronchoscope. After the injection is complete, the saline solution is drawn again and injected repeatedly until the mucus is flushed away or diluted. However, this method involves repeated drawing and injecting of saline solution, which exposes the syringe needle to frequent contact with the outside environment, increasing the risk of saline contamination and significantly raising the risk of infection during the flushing process.

[0004] Currently, some automated bronchoscope irrigation devices, such as CN219557236U, have emerged on the market. These devices can automatically extract and inject saline solution, avoiding the infection risk associated with frequent contact between the syringe needle and the external environment. However, these automated devices typically require power equipment, resulting in complex structures and high costs. Since bronchoscope irrigation devices are disposable medical devices, the high cost leads to a heavy burden on healthcare providers, hindering widespread adoption and use. Utility Model Content

[0005] The purpose of this application is to provide a bronchoscope irrigation device that solves the problems of increased infection risk from traditional manual irrigation and high cost of automatic irrigation devices.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] A bronchoscope irrigation device includes a bronchoscope, an irrigation tube, a flexible irrigation fluid container, and a syringe. The side hole of the bronchoscope is connected to one end of the irrigation tube, the other end of the irrigation tube is connected to the flexible irrigation fluid container, and the syringe is connected to the irrigation tube.

[0008] The flushing tube is equipped with a control switch, which is used to control the syringe to communicate with the flexible flushing fluid container and disconnect from the side hole, and to control the syringe to disconnect from the flexible flushing fluid container and communicate with the side hole.

[0009] Furthermore, the flushing tube includes an injection tube, a suction tube, and a medical three-way valve that also serves as the control switch. The side hole is connected to one end of the injection tube, the other end of the injection tube is connected to the first end of the medical three-way valve, the second end of the medical three-way valve is connected to one end of the suction tube, the other end of the suction tube is connected to the flexible flushing fluid container, and the syringe is connected to the third end of the medical three-way valve.

[0010] Furthermore, the flexible flushing fluid container is connected to the flushing pipe via a detachable structure.

[0011] Furthermore, the detachable structure includes a threaded structure.

[0012] Furthermore, the flexible flushing fluid container comprises at least two.

[0013] Furthermore, the flexible rinsing fluid container has a volume of 100 ml, and the syringe has a volume of 20 ml.

[0014] Furthermore, the flexible flushing fluid container includes a flexible flushing fluid bag or a soft-walled flushing fluid bottle.

[0015] Furthermore, a spare port is provided on the wall of the flushing pipe near the side hole, and the spare port is provided with a sealing cap that can be opened and closed.

[0016] Furthermore, the sealing cap is connected to the flushing tube via a connecting strap.

[0017] Furthermore, it also includes a disposable packaging bag, and the rinsing tube, the flexible rinsing fluid container, the syringe and the control switch are all located inside the disposable packaging bag.

[0018] The beneficial effects of this application are:

[0019] 1. The bronchoscope irrigation device provided in this application connects the bronchoscope side hole, the flexible irrigation fluid container and the syringe together through the irrigation tube. The control switch provided on the irrigation tube can control the connection and disconnection between the syringe and the flexible irrigation fluid container and between the syringe and the side hole of the bronchoscope. Thus, the irrigation fluid in the flexible irrigation fluid container can be drawn out by the syringe and then injected into the side hole of the bronchoscope to achieve irrigation of the bronchoscope observation area.

[0020] 2. The bronchoscope flushing device provided in this application embodiment ensures that the flushing fluid is completely isolated from the outside world throughout the entire process from the flexible flushing fluid container to the side hole of the bronchoscope through a fully enclosed flushing fluid transmission system. This effectively avoids the risk of flushing fluid contamination caused by the frequent exposure of the syringe needle to the external environment in traditional manual flushing methods, thereby significantly reducing the risk of infection during the flushing process of the bronchoscope.

[0021] 3. The bronchoscope irrigation device provided in this application mainly consists of an irrigation tube, a flexible irrigation fluid container, a syringe, and a control switch. Compared with existing automatic irrigation devices, it does not require complex components such as electric devices, which simplifies the structure of the device, significantly reduces the production cost of the entire irrigation device, effectively reduces the procurement cost burden of medical institutions, makes it more suitable for single use, and is conducive to widespread promotion and use.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] See Figure 1 This application provides a bronchoscope irrigation device, including a bronchoscope 1, an irrigation tube 2, a flexible irrigation fluid container 3, and a syringe 4. The side hole 11 of the bronchoscope 1 is connected to one end of the irrigation tube 2, and the other end of the irrigation tube 2 is connected to the flexible irrigation fluid container 3. The syringe 4 is connected to the irrigation tube 2. The irrigation tube 2 is provided with a control switch 5, which is used to control the syringe 4 to connect with the flexible irrigation fluid container 3 and disconnect from the side hole 11, and to control the syringe 4 to disconnect from the flexible irrigation fluid container 3 and connect with the side hole 11.

[0040] The flexible flushing solution container 3 stores flushing solution. Its flexible structure allows deformation when the flushing solution is drawn from the container, thereby automatically adjusting the pressure difference inside and outside the container to ensure smooth extraction and use of the flushing solution. For example, the flexible flushing solution container 3 may include a flexible flushing solution bag or a soft-walled flushing solution bottle, and the flushing solution in the flexible flushing solution container 3 may include physiological saline or sterile water for injection.

[0041] The irrigation tube 2 is used to deliver irrigation fluid and is typically made of transparent or translucent medical-grade plastic. One end of the irrigation tube 2 is connected to the side port of the fiberoptic bronchoscope 1, and the other end is connected to the flexible irrigation fluid container 3. The irrigation tube 2 is connected to the syringe 4 at the position between the two ends. The irrigation tube 2 is equipped with a control switch 5 for controlling the on / off state of the irrigation tube 2. The control switch 5 has two control states: fluid aspiration state and fluid injection state.

[0042] The "liquid aspiration state" refers to the state where the syringe 4 is connected to the flexible irrigation fluid container 3 and disconnected from the side hole 11 of the fiberoptic bronchoscope 1. In this state, the irrigation fluid in the flexible irrigation fluid container 3 can be drawn into the syringe 4 through the irrigation tube 2. The "liquid injection state" refers to the state where the syringe 4 is disconnected from the flexible irrigation fluid container 3 and connected to the side hole 11 of the fiberoptic bronchoscope 1. In this state, the irrigation fluid in the syringe 4 can be injected into the side hole 11 of the fiberoptic bronchoscope 1 through the irrigation tube 2 to irrigate the observation area.

[0043] See Figure 1 During various diagnostic and therapeutic procedures performed by doctors using a fiberoptic bronchoscope 1 on patients' respiratory diseases, when the observed area is covered with viscous secretions or mucus, the fiberoptic bronchoscope irrigation device provided in this application embodiment can be used to irrigate the observed area. The specific irrigation process is as follows:

[0044] S1. Using the control switch 5, the syringe 4 is connected to the flexible flushing fluid container 3 and disconnected from the side hole 11. In this state, the syringe 4 is controlled to draw the flushing fluid in the flexible flushing fluid container 3 into the syringe 4 through the flushing tube 2.

[0045] S2. Using the control switch 5, the syringe 4 is disconnected from the flexible flushing fluid container 3 and connected to the side hole 11. In this state, the syringe 4 is controlled to inject the flushing fluid inside into the side hole 11 of the bronchoscope 1 through the flushing tube 2.

[0046] S3. Repeat steps S1 and S2 until the mucus in the observed area is washed away or diluted.

[0047] After rinsing, remove the rinsing tube 2 from the side hole 11 of the bronchoscope 1, and then discard the rinsing tube 2, syringe 4, flexible rinsing fluid container 3 and control switch 5 into the medical waste bin.

[0048] The bronchoscope flushing device provided in this application embodiment connects the side hole 11 of the bronchoscope 1, the flexible flushing fluid container 3, and the syringe 4 together through the flushing tube 2. The control switch 5 provided on the flushing tube 2 can control the connection and disconnection between the syringe 4 and the flexible flushing fluid container 3, as well as between the syringe 4 and the side hole 11 of the bronchoscope 1. Thus, the syringe 4 can be used to extract the flushing fluid from the flexible flushing fluid container 3 and then inject it into the side hole 11 of the bronchoscope 1 to flush the observation area of ​​the bronchoscope.

[0049] The bronchoscope flushing device provided in this application embodiment ensures that the flushing fluid is completely isolated from the outside world throughout the entire process from the flexible flushing fluid container 3 to the side hole 11 of the bronchoscope 1 through a fully enclosed flushing fluid transmission system. This effectively avoids the risk of flushing fluid contamination caused by the frequent exposure of the syringe needle to the external environment in traditional manual flushing methods, thereby significantly reducing the risk of infection during the flushing process of the bronchoscope.

[0050] The fiberoptic bronchoscope irrigation device provided in this application mainly consists of an irrigation tube 2, a flexible irrigation fluid container 3, a syringe 4, and a control switch 5. Compared with existing automatic irrigation devices, it does not require complex components such as electric devices, which simplifies the structure of the device, significantly reduces the production cost of the entire irrigation device, effectively reduces the procurement cost burden of medical institutions, makes it more suitable for single use, and is conducive to widespread promotion and use.

[0051] The flushing tube 2 can be a single piece with a connection port in the middle, through which the syringe 4 can communicate with the flushing tube 2.

[0052] In some embodiments, see Figure 2 The flushing tube 2 may include a first tube 26, a three-way tube 27, and a second tube 28. One end of the first tube 26 is connected to the flexible flushing fluid container 3, and the other end of the first tube 26 is connected to the first end of the three-way tube 27. The second end of the three-way tube 27 is connected to one end of the second tube 28, and the third end of the three-way tube 27 is connected to the syringe 4. The other end of the second tube 28 is connected to the side hole 11 of the fiberoptic bronchoscope 1. The connection between the three-way tube 27 and the first tube 26, the second tube 28, and the syringe 4 can be a threaded connection or a plug-in connection. This segmented structure facilitates the connection and disconnection of the syringe 4 and the flushing tube 2.

[0053] In some embodiments, see Figure 2 The control switch 5 may include two roller clamps, namely a first roller clamp 51 disposed on the first tube 26 and a second roller clamp 52 disposed on the second tube 28. The first roller clamp 51 can control the on / off state of the first tube 26, and the second roller clamp 52 can control the on / off state of the second tube 28. Of course, the roller clamps can also be replaced with stop clamps, which are not specifically limited here.

[0054] During operation, firstly, open the first roller clamp 51 to connect the syringe 4 with the flexible irrigation fluid container 3, and close the second roller clamp 52 to disconnect the syringe 4 from the side hole 11. At this time, the syringe 4 can be controlled to draw the irrigation fluid in the flexible irrigation fluid container 3 into the syringe 4 through the first tube 26. Then, close the first roller clamp 51 to disconnect the syringe 4 from the flexible irrigation fluid container 3, and open the second roller clamp 52 to connect the syringe 4 with the side hole 11. At this time, the syringe 4 can be controlled to inject the irrigation fluid inside into the side hole 11 of the fiberoptic bronchoscope 1 through the second tube 28.

[0055] In some embodiments, see Figure 3 , Figure 4 The flushing tube 2 includes an injection tube 21, a suction tube 22, and a medical three-way valve 23 that also serves as a control switch 5. The side hole 11 is connected to one end of the injection tube 21, the other end of the injection tube 21 is connected to the first end of the medical three-way valve 23, the second end of the medical three-way valve 23 is connected to one end of the suction tube 22, the other end of the suction tube 22 is connected to the flexible flushing fluid container 3, and the syringe 4 is connected to the third end of the medical three-way valve 23.

[0056] Correspondingly, by setting a medical three-way valve 23 that also functions as a control switch 5, during operation, simply holding the operating handle of the medical three-way valve 23 and rotating the valve core 90° will connect the syringe 4 to the flexible irrigation fluid container 3 while simultaneously disconnecting the syringe 4 from the side port 11 of the fiberoptic bronchoscope 1. At this time, the syringe 4 can be controlled to draw the irrigation fluid in the flexible irrigation fluid container 3 into the syringe 4 through the aspiration tube 22. Then, holding the operating handle of the medical three-way valve 23 and rotating the valve core 90° in the opposite direction will disconnect the syringe 4 from the flexible irrigation fluid container 3 while simultaneously connecting the syringe 4 to the side port 11 of the fiberoptic bronchoscope 1. At this time, the syringe 4 can be controlled to inject the irrigation fluid inside into the side port 11 of the fiberoptic bronchoscope 1 through the injection tube 21. Compared with the control switch 5 composed of two roller clamps, the operation of the medical three-way valve 23 is simpler and can improve irrigation efficiency.

[0057] In some embodiments, see Figure 1 , Figure 2 The flexible irrigation fluid container 3 is connected to the irrigation tube 2 via a detachable structure. Accordingly, during irrigation, when the irrigation fluid is insufficient, the detachable structure allows medical personnel to quickly replace the flexible irrigation fluid container 3 to replenish the irrigation fluid without replacing the entire irrigation device. For example, the detachable structure includes a threaded structure, which provides a tight and reliable connection. Of course, the detachable structure can also include a plug-in connection structure. The irrigation tube 2 and the side hole 11 of the bronchoscope 1 can also be connected via a plug-in connection or a threaded connection.

[0058] In some embodiments, the flexible flushing fluid container 3 comprises at least two. Accordingly, by providing at least two flexible flushing fluid containers 3, one for the current flushing operation and the other as a backup, the continuity of the flushing operation is ensured.

[0059] For example, each flexible irrigation fluid container 3 has a volume of 100 ml, and the syringe 4 has a volume of 20 ml. Accordingly, the 100 ml flexible irrigation fluid container 3 meets the needs of most routine irrigation operations; this capacity is neither too large to cause inconvenience in carrying and handling, nor too small to require frequent replacement. The 20 ml syringe 4 can provide sufficient fluid in a single operation, avoiding frequent operations due to insufficient volume and improving work efficiency. Both 100 ml and 20 ml are standard units of measurement, facilitating quick identification and recording of irrigation fluid usage by medical personnel. Of course, the volumes of the flexible irrigation fluid container 3 and syringe 4 can also adopt other existing specifications, which are not specifically limited here.

[0060] In some embodiments, see Figure 5 The flushing tube 2 has a spare port 211 on its wall adjacent to the side hole 11. The spare port 211 has a sealing cap 24 that can be opened and closed. For example, the spare port 211 is located on the wall of the injection tube 21, and the sealing cap 24 and the spare port 211 can be connected by a plug-in connection or a threaded connection.

[0061] Correspondingly, a spare port 211 is provided on the wall of the irrigation tube 2 near the side hole 11 of the bronchoscope 1, and equipped with a sealing cap 24 that can be opened and closed. When a biopsy specimen needs to be obtained during diagnostic and therapeutic procedures, the sealing cap 24 can be opened, and the sampling instrument can be inserted into the side hole 11 of the bronchoscope 1 through the spare port 211 to sample the target site. The entire sampling operation does not require disconnecting the irrigation tube 2. After the biopsy specimen is extracted, the sealing cap 24 is closed to effectively seal the spare port 211, and the irrigation operation can continue. Of course, other operations can also be performed using the spare port 211, which are not specifically limited here.

[0062] In some embodiments, see Figure 5 The sealing cap 24 is connected to the flushing pipe 2 via the connecting strap 25. Accordingly, when the sealing cap 24 is opened, the sealing cap 24 and the flushing pipe 2 are still physically connected via the connecting strap 25 to prevent the sealing cap 24 from being lost.

[0063] In some embodiments, see Figure 6 It also includes a disposable packaging bag 6, a rinsing tube 2, a flexible rinsing fluid container 3, a syringe 4, and a control switch 5, all of which are located inside the disposable packaging bag 6.

[0064] Accordingly, by placing the flushing tube 2, flexible flushing fluid container 3, syringe 4, and control switch 5 inside a disposable packaging bag 6, medical staff can directly retrieve and operate upon need, eliminating the need to search for different medical devices in multiple locations, reducing preparation time, and improving work efficiency. The outlet of the flexible flushing fluid container 3 is equipped with a cap.

[0065] Of course, the disposable packaging bag 6 can also contain individually packaged alcohol gauze pads, individually packaged paraffin oil gauze pads, and other auxiliary materials. By integrating the necessary instruments and auxiliary materials for rinsing into one packaging bag, medical staff can take out all the necessary items at once, reducing preparation time and steps.

[0066] Example 1:

[0067] See Figure 6 The bronchoscope irrigation device provided in this embodiment includes a disposable packaging bag 6. The disposable packaging bag 6 contains two 100ml flexible irrigation fluid containers 3, an injection tube 21, a suction tube 22, a medical three-way valve 23, and a 20ml syringe 4. The flexible irrigation fluid container 3 is a flexible irrigation fluid bag with a cap, and the irrigation fluid inside is physiological saline.

[0068] The flushing process using the bronchoscope flushing device of this embodiment is as follows:

[0069] Step 1: Open the disposable packaging bag 6, connect the injection tube 21, the suction tube 22 and the medical three-way valve 23 together to form the flushing tube 2, connect the syringe 4 to the medical three-way valve 23, connect the suction tube 22 to the flexible flushing fluid container 3, and connect the injection tube 21 to the side hole 11 of the fiberoptic bronchoscope 1.

[0070] Step 2: Hold the operating handle of the medical three-way valve 23 and rotate the valve core 90° to connect the syringe 4 with the flexible irrigation solution container 3 and disconnect it from the side hole 11 of the fiberoptic bronchoscope 1. Control the syringe 4 to draw the physiological saline in the flexible irrigation solution container 3 into the syringe 4 through the aspiration tube 22.

[0071] Step 3: Hold the operating handle of the medical three-way valve 23 and rotate the valve core 90° in the opposite direction to disconnect the syringe 4 from the flexible irrigation fluid container 3 and connect it to the side hole 11 of the fiberoptic bronchoscope 1. Control the syringe 4 to inject the irrigation fluid inside into the side hole 11 of the fiberoptic bronchoscope 1 through the injection tube 21.

[0072] Step 4: Repeat steps 2 and 3 until the mucus at the observation site is flushed away or diluted. If the saline solution in the flexible flushing solution container 3 runs out during flushing, remove it and replace it with another flexible flushing solution container 3. After flushing, remove the infusion tube 21 from the side port 11 of the fiberoptic bronchoscope 1 and dispose of it in the medical waste bin.

[0073] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
