[0003] Common purging device for medical gas pipeline installation uses air compressor to intermittently purge when purging, and the purging pressure should not exceed the design pressure of medical gas pipeline. When observing that the purging operation is completed and no visible dirt is discharged, a white cloth or a target plate coated with white paint is arranged at the exhaust port of the medical gas pipeline for inspection. If there is no rust, soil or other dirt on the target plate or white cloth within 5 minutes, the purging operation is qualified.
[0004] However, this method will discharge impurities during purging. In order to collect the discharged impurities, a blocking and collecting device is added at the outlet of the pipeline to collect the impurities. However, the blocking and collecting device is installed by pipe clamp and bolt, which makes the disassembly and assembly process inconvenient and not conducive to multi-pipeline purging. It cannot meet the working requirements of medical pipeline cleaning. Therefore, a purging device for medical gas pipeline installation is proposed. UTILITY MODEL CONTENT

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a technical solution: a purging device for installing medical gas pipelines, comprising a main pipe 1, a sleeve 2, a connecting frame 3, a mounting frame 4, a collection bag 5, a strip box 6, an insert rod 7, a clamping block 8, a spring 9, a through hole 10, a shaft 11, a first bevel tooth 12, a second bevel tooth 13, a prism 14, a knob 15, a painted plate 16, a stepped ring packing 17, and a flange 18.
[0029] Please see Figure 1 The air outlet of the main pipe 1 is fitted with a sleeve block 2. Please refer to [link / reference]. Figure 2 and Figure 3 A connecting frame 3 is installed on the top of the sleeve block 2. Insert rods 7 are inserted into both sides of the inside of the connecting frame 3. Clamping blocks 8 are connected to the bottom of the insert rods 7. Springs 9 are sleeved on the lower side of the outside of the insert rods 7. Through holes 10 are opened inside the sleeve block 2 and the clamping blocks 8. The upper and lower ends of the springs 9 are connected to the corresponding positions of the lower part of the connecting frame 3 and the upper part of the clamping blocks 8. The outer side of the through holes 10 is rounded. The upper part of the insert rods 7 passes through the corresponding position of the top of the connecting frame 3. The length of the insert rods 7 is greater than the height of the connecting frame 3.
[0030] Mounting bracket 4 is connected to the bottom of sleeve block 2. A collection bag 5 is installed at the lower part of mounting bracket 4, and a crate 6 is installed on the upper right side of mounting bracket 4. Please refer to [link / reference]. Figure 4 The inner cavity of carton 6 is connected to shaft 11 via ball bearings. Please refer to [link / reference]. Figure 3 By pressing the insert rod 7, the through hole 10 inside the clamping block 8 coincides with the through hole 10 inside the sleeve block 2, so that the clamping block 8 and the sleeve block 2 can be directly sleeved on the outside of the main pipe 1. Releasing the insert rod 7 will cause the clamping block 8 to be clamped on the outside of the main pipe 1 under the action of the spring 9, which facilitates disassembly and assembly and improves the convenience of purging multiple sets of medical tubing. At the same time, the added prism 14 can block the blown impurities and make the impurities fall into the inside of the collection bag 5, which facilitates the centralized treatment of dirt or impurities.
[0031] Please see Figure 4 The first bevel tooth 12 is coaxially sleeved on the outside of the shaft 11. A second bevel tooth 13 is inserted into the top of the carton 6 via a rotating shaft. A prism 14 is coaxially mounted on the top of each of the second bevel teeth 13. The front end of the shaft 11 passes through the corresponding position of the carton 6. A knob 15 is coaxially mounted on the front end of the shaft 11. The knob 15 has anti-slip textures on its exterior. The number of the first bevel teeth 12 and the second bevel teeth 13 is 4-8 sets. All the first bevel teeth 12 mesh with the second bevel teeth 13. Please refer to [link / reference]. Figure 5The prism 14 has an equilateral triangular cross-section, and a paint plate 16 is adhered to its rear. Compared to a flat, blocking structure, the prism 14 provides a larger contact area, which helps to more effectively capture and collect the dirt discharged during the purging process, improving collection efficiency. Furthermore, the airflow generates more turbulence upon contact with the prism 14, and this turbulence helps to separate the dirt from the airflow, making it easier to collect. (See [link to relevant documentation]). Figure 1 The air inlet of the main pipe 1 is fitted with a stepped ring packing 17, and the air inlet of the main pipe 1 is fitted with a flange 18.
[0032] This solution allows the clamping block 8 and sleeve 2 to be directly fitted onto the outside of the main pipe 1 by pressing the insert rod 7 so that the through hole 10 inside the clamping block 8 coincides with the through hole 10 inside the sleeve block 2. Releasing the insert rod 7 allows the clamping block 8 to be clamped onto the outside of the main pipe 1 under the action of the spring 9, which facilitates disassembly and assembly and improves the convenience of purging multiple sets of medical tubing. At the same time, the added prism 14 can block the blown impurities and make them fall into the collection bag 5, which facilitates the centralized treatment of dirt or impurities. In addition, the added prism 14 provides a larger contact area compared to the flat blocking structure, which helps to capture and collect the dirt discharged during the purging process more effectively and improves the collection efficiency. Furthermore, the airflow generates more turbulence when it comes into contact with the prism 14, and the turbulence helps to separate the dirt from the airflow, making it easier to collect.
