Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an automatic bronchoscope irrigation device. Background Technology

[0002] Bronchoscopic alveolar lavage is a technique developed based on bronchoscopy. Simply put, it involves using a syringe to draw up physiological saline and injecting it into the bronchus through the bronchoscope's forceps. The saline is then aspirated under negative pressure and collected for testing. This lavage fluid can be used for the analysis of cells, proteins, and other components, as well as for the etiological detection and culture of pulmonary infectious diseases. Bronchoscopic alveolar lavage can also be used for airway clearance in patients with difficulty expectorating sputum, reducing the risk of infection, maintaining airway patency, and ensuring oxygenation levels. Therefore, bronchoscopic alveolar lavage has made a significant contribution to the diagnosis and treatment of lung diseases.

[0003] However, in practice, the above-mentioned device has the following problems: 1. The syringe capacity is small, and the amount of saline injected at one time is insufficient for alveolar lavage. Multiple injections are required to achieve the required volume, making the operation cumbersome, increasing labor intensity, and increasing the chance of saline contamination. 2. Alveolar lavage cannot be performed by a single bronchoscope operator; it requires the assistance of professional personnel, which increases the workload. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model provides an automatic bronchoscopy irrigation device, which is simple to operate and uses a turbine to aspirate physiological saline and inject it into the bronchus.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic bronchoscope irrigation device, comprising a shell, a groove, a conduit, a flushing pipe, a flexible needle, and a turbine. The shell is hollow and tile-shaped, with the groove longitudinally arranged on its outer curved surface. The groove is elongated and widens into a circular groove in the middle. The conduit can be inserted into the groove, with one end connected to the flushing pipe and the other end connected to the flexible needle. The middle section is expanded into a flattened drum shape. The turbine is disposed therein. The flushing pipe is a flexible tube that can be bent, with one end being a rigid tube that can be inserted into the bronchoscope clamp channel for connection. The aforementioned flexible needle consists of a flexible tube and a hollow needle tip. The needle tip can be inserted into a saline bottle through a stopper. The automatic bronchoscope irrigation device also includes a battery, a motor, a switch, and a latch. The battery and the motor are both housed within the outer casing. The rotating shaft of the motor passes through the wall of the outer casing and is connected to the turbine, allowing it to rotate as a unit. The switch is located on the outer casing and controls the power supply to the battery and the motor. The latch is flexible and connects to the outer casing to form a movable ring, which can be fixed to the bronchoscope handle.

[0006] Compared with the prior art, the advantages of this utility model are: it uses an electric motor to drive the turbine to rotate, which can automatically draw physiological saline through the flexible needle and catheter, and inject it into the bronchoscope through the flushing tube into the bronchus, simplifying the operation and reducing the amount of labor and the chance of physiological saline contamination. Attached Figure Description

[0007] Figure 1 is a three-dimensional structural schematic diagram of this utility model; Figure 2 is a three-dimensional structural diagram of the present invention in its disassembled state. Detailed Implementation

[0008] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this is not intended to limit the present invention.

[0009] Example 1: As shown in the figure, an automatic bronchoscope irrigation device includes a housing 1, a groove 8, a conduit 2, a flushing pipe 3, a flexible needle 7, and a turbine 6. The housing 1 is hollow and tile-shaped, with a longitudinally arranged groove 8 on its outer curved surface. The groove 8 is elongated and widens into a circular groove in the middle. The conduit 2 can be inserted into the groove 8, with one end connected to the flushing pipe 3 and the other end connected to the flexible needle 7. The middle section of the conduit 2 is expanded into a flattened drum shape, and the turbine 6 is located therein. The flushing pipe 3 is a flexible tube that can be bent, with one end being a rigid tube that can be inserted into the bronchoscope's clamp channel for connection. The flexible needle 7 consists of a flexible tube and a hollow needle. The needle tip can be inserted into the saline bottle through the stopper. The automatic bronchoscope irrigation device also includes a battery 9, a motor 10, a switch 5, and a latch 4. The battery 9 and the motor 10 are both located inside the housing 1. The rotating shaft of the motor 10 passes through the wall of the housing 1 and is connected to the turbine 6 so that they can rotate together. The switch 5 is located on the housing 1 and controls the power supply to the battery 9 and the motor 10. The latch 4 can be bent and connected to the housing 1 to form a movable ring, which can be fixed on the bronchoscope handle.

[0010] Example 2: As shown in the figure, the other structures are the same as in Example 1. The difference is that the catheter 2 is inserted into the groove 8, the turbine 6 is connected to the rotating shaft of the motor 10, the flushing pipe 3 is connected to one end of the catheter 2, and the rigid tube end is inserted into the bronchoscope forceps channel and connected. The flexible needle 7 is connected to the other end of the catheter 2, and the needle tip is inserted into the bottle through the stopper of the saline bottle. When the switch 5 is turned on, the motor 10 drives the turbine 6 to rotate as a whole. The saline is drawn through the flexible needle 7 and the catheter 2 and injected into the bronchoscope forceps channel through the flushing pipe 3 and into the bronchus. The irrigation volume can be adjusted according to clinical needs.
