Description

Technical Field

[0001] This utility model relates to the field of bronchoscope technology, specifically to a bronchoscope anti-leakage negative pressure interface structure. Background Technology

[0002] During bronchoscopy, it is necessary to prevent gas leakage in order to ensure the accuracy and reliability of the test results. At this time, the anti-leakage negative pressure interface structure is particularly important. This structure supports the smooth examination of the bronchus lobe, segment and subsegment bronchi through negative pressure interface and effective anti-leakage measures.

[0003] In existing technologies, the anti-leakage negative pressure interface structure of bronchoscopes suffers from insufficient stability and accuracy. Specifically, the suction syringe is typically inserted directly into the connection hole on the bronchoscope body. During testing, the syringe is fixed by hand, which can easily lead to displacement or loosening during suction, thus affecting the effectiveness and accuracy of negative pressure suction. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof negative pressure interface structure for a bronchoscope. Through the adsorption of the suction cup, the pressure fluctuation during the subsequent air extraction process is effectively reduced, ensuring the stability of the air pressure environment during the test.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bronchoscope anti-leakage negative pressure interface structure, including a bronchoscope body, an operating component at the bottom of the bronchoscope body, a detection tube for checking the bronchus connected to the bottom of the operating component, a connecting assembly outside the bronchoscope body, and an aspiration syringe for aspirating the detection tube in the connecting assembly.

[0006] The connecting assembly includes a first connecting plate disposed outside the bronchoscope body, and an assembly base is provided at the top of the first connecting plate.

[0007] The assembly base is provided with a syringe fixing assembly for fixing the outer wall of the suction syringe. The syringe fixing assembly includes a mounting shaft provided in the assembly base, and a positioning clamp for fixing the suction syringe is provided outside the mounting shaft.

[0008] Preferably, the bronchoscope body has a connecting hole on its exterior that can communicate with the suction syringe, and a connecting pipe is provided on its exterior.

[0009] Preferably, there are two sets of mounting shafts, which are symmetrically arranged in the assembly base.

[0010] Preferably, the syringe fixing assembly further includes a connecting seat disposed outside the assembly base and a second connecting plate disposed outside the positioning clamp, wherein a first spring is disposed between the second connecting plate and the connecting seat, and a damper body is disposed in the first spring.

[0011] Preferably, the syringe fixing assembly further includes a rubber pad disposed outside the positioning clamp to reduce damage to the outer wall of the suction syringe.

[0012] Preferably, the assembly base is provided with an auxiliary fixing component for auxiliary fixing of the bottom end of the suction syringe. The auxiliary fixing component includes a mounting groove formed in the assembly base, and a suction cup for adsorbing the bottom end of the suction syringe is provided in the mounting groove. The bottom end of the suction cup is connected to a connecting pipe.

[0013] Preferably, the suction cup has a hole through which the suction syringe passes.

[0014] Preferably, a bronchoscope control component is provided at the top of the bronchoscope body, and a connecting cable for connecting to the testing equipment is fixed to the outside of the bronchoscope control component.

[0015] Compared with the prior art, this utility model provides a leak-proof negative pressure interface structure for a bronchoscope, which has the following advantages:

[0016] 1. The leak-proof negative pressure interface structure of this bronchoscope is crucial for maintaining a stable air pressure environment when using the bronchoscope and other components in conjunction with testing equipment to examine the child's bronchi. This device effectively reduces air pressure fluctuations during subsequent air aspiration through the suction cup, ensuring a stable air pressure environment during the examination. Simultaneously, the coordinated action of components such as the positioning clip, the first spring, and the second connecting plate securely fixes the aspiration syringe, preventing safety hazards caused by loosening or detachment of the syringe, and further improving the stability and safety of air pressure regulation.

[0017] 2. The bronchoscope's leak-proof negative pressure interface structure automatically triggers the rotation of the positioning clamp upon insertion of the suction syringe, and automatically fixes it after insertion via the restoring force of the first spring. This not only simplifies the operation process and reduces the complexity of manual operation, but also slows down the rebound speed of the positioning clamp through the buffering effect of the damper body, avoiding potential injury to the suction syringe or operator caused by excessive rebound. Simultaneously, the protective function of the rubber pad effectively prevents damage to the outer wall of the suction syringe, extending its service life. Attached Figure Description

Detailed Implementation

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a bronchoscope anti-leakage negative pressure interface structure, including a bronchoscope body 1, an operating component 2 is provided at the bottom of the bronchoscope body 1, a detection tube 3 for checking the bronchus is connected to the bottom of the operating component 2, a connecting component 6 is provided outside the bronchoscope body 1, and an air suction syringe 7 for suctioning the detection tube 3 is provided in the connecting component 6.

[0027] The connecting component 6 includes a first connecting plate 61 disposed outside the bronchoscope body 1, and an assembly base 64 is disposed at the top of the first connecting plate 61.

[0028] The assembly base 64 is equipped with a syringe fixing assembly 8 for securing the outer wall of the suction syringe 7. The syringe fixing assembly 8 includes a mounting shaft 82 disposed in the assembly base 64, and a positioning clamp 83 for securing the suction syringe 7 is disposed outside the mounting shaft 82. This design achieves stable installation and positioning of the suction syringe 7 by connecting the assembly 6 and the syringe fixing assembly 8, ensuring the stability and accuracy of the suction process and effectively preventing air leakage.

[0029] Furthermore, the bronchoscope body 1 has a connecting hole 62 on its exterior that can communicate with the suction syringe 7, and a connecting pipe 63 is provided on its exterior. The connection hole 62 and the connecting pipe 63 enable the suction syringe 7 to communicate smoothly with the interior of the bronchoscope body 1, realizing the negative pressure suction function, while ensuring the compactness of the structure and the convenience of operation.

[0030] Furthermore, two sets of mounting shafts 82 are provided, symmetrically arranged in the assembly base 64. This enhances the stability and load-bearing capacity of the syringe fixing assembly 8, ensuring that the suction syringe 7 will not shift or loosen during the fixing process.

[0031] Furthermore, the syringe fixing assembly 8 also includes a connecting seat 81 disposed outside the assembly base 64 and a second connecting plate 85 disposed outside the positioning clamp 83. A first spring 86 is disposed between the second connecting plate 85 and the connecting seat 81, and a damper body 87 is disposed in the first spring 86. The combined use of the first spring 86 and the damper body 87 not only realizes the automatic reset function of the positioning clamp 83, but also reduces the impact during the reset process, thereby improving the safety of use.

[0032] Furthermore, the syringe fixing assembly 8 also includes a rubber pad 84 disposed outside the positioning clip 83 to reduce damage to the outer wall of the suction syringe 7. The rubber pad 84 effectively protects the outer wall of the suction syringe 7 from damage and extends the service life of the suction syringe 7.

[0033] Furthermore, the assembly base 64 is provided with an auxiliary fixing component 9 for further securing the bottom end of the suction syringe 7. The auxiliary fixing component 9 includes a mounting groove 91 formed in the assembly base 64, and a suction cup 92 is provided in the mounting groove 91 to attract the bottom end of the suction syringe 7. The bottom end of the suction cup 92 is connected to the connecting pipe 63. The design of the auxiliary fixing component 9 and the suction cup 92 further enhances the fixing effect of the suction syringe 7, ensuring the stability and reliability of the suction process.

[0034] Furthermore, the suction cup 92 has a hole 93 through which the suction syringe 7 passes. The hole 93 allows the suction syringe 7 to pass smoothly through the suction cup 92, while ensuring the suction cup 92's adsorption effect on the bottom of the suction syringe 7.

[0035] Example 2: Please refer to Figures 1-2Furthermore, in conjunction with Embodiment 1, a bronchoscope control component 4 is provided at the top of the bronchoscope body 1, and a connecting cable 5 for connecting to the testing equipment is fixed to the outside of the bronchoscope control component 4. The bronchoscope control component 4 and the connecting cable 5 enable the operator to conveniently control the working status of the bronchoscope and transmit data with the testing equipment, thereby improving testing efficiency and accuracy.

[0036] In actual operation, firstly, the bronchoscope body 1, operating components 2, detection tube 3, bronchoscope control components 4, and connecting cable 5 are used in conjunction with the detection equipment to examine the child's bronchi. When it is necessary to adjust the air pressure environment in the detection tube 3, the operation is as follows:

[0037] Insert the suction syringe 7 into the hole 93 of the suction cup 92, press down the suction syringe 7 to expel the air in the suction cup 92, so that the bottom of the suction cup 92 can be attracted, thereby reducing the pressure fluctuation during the subsequent suction process.

[0038] When the suction syringe 7 is inserted, it contacts the positioning clips 83 on both sides, causing the two sets of positioning clips 83 to rotate to both sides. After insertion, the first spring 86 returns to its original position, driving the second connecting plate 85 to move, causing the positioning clips 83 to return to their initial position and fix the suction syringe 7. The damper body 87 slows down the rebound speed of the positioning clips 83, and the rubber pad 84 protects the outer wall of the suction syringe 7 from damage. After assembly, the air pressure can be dynamically adjusted by pushing the suction syringe 7.

[0039] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
