Technical Field

[0001] The utility model relates to the technical field of atomization pipelines of a ventilator, in particular to an atomization pipeline component for a ventilator. Background Art

[0002] A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] During actual use, especially during atomization therapy, the atomization pipe needs to be connected to the ventilator, which causes the problem of being unable to use them synchronously. Therefore, the existing technology usually sets a multi-way valve structure to achieve simultaneous connection of the breathing and atomization pipes.

[0004] However, after the nebulization treatment is completed, a large amount of nebulized medicine will remain on the inner wall of the nebulization pipe, which will affect the use of the breathing pipe and even cause problems such as pneumonia. In order to adapt to the use of different lengths, the existing nebulization pipes mostly use a foldable hose structure, which makes it difficult to clean the nebulization pipe.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 , the utility model provides a technical solution:

[0023] Example 1: An atomizing pipe assembly for a ventilator comprises a first end block 2 and a second end block 12, wherein one end of the first end block 2 is connected to the ventilator 1, and the other side of the first end block 2 is provided with a pair of symmetrically distributed first air nozzles 3 and a second air nozzle 4 located in the middle position, wherein the second air nozzle 4 is provided with an elastically mounted piston 10, and the inner wall of the second air nozzle 4 is provided with a side groove 8, the second end block 12 is provided with a folding hose 11 connected to the first air nozzle 3, and the second end block 12 is provided with a heating rod 16 fixedly inserted in the second air nozzle 4, and the heating rod 16 is provided with a heating resistance wire 18.

[0024] During use, the first end block 2 is installed on the ventilator 1, and the second end block 12 is connected to the nebulizer inhaler. The first end block 2 and the second end block 12 are connected through the foldable hose 11. At this time, due to the elastic compression of the piston 10, the second air nozzle 4 cannot exhaust.

[0025] After use, the folding hose 11 is folded and stored to reduce its length, thereby realizing the insertion of the second end block 12 on the first end block 2. During the insertion of the heating rod 16, the piston 10 is squeezed to make the piston 10 slide, thereby causing the gas to be discharged along the side groove 8 to the heating rod 16. Under the heating of the heating resistance wire 18, high-temperature hot air is formed, and heat is transferred to the stored folding hose 11 to achieve the purpose of heating the pipeline. The stored folding hose 11 is fully heated with hot air in the small space surrounded by the end blocks, so that the residual medicine in the pipeline is fully volatilized, and the residual medicine is discharged in conjunction with continuous exhaust, which greatly reduces the mutual influence between atomization and breathing.

[0026] Example 2: Based on Example 1, a pair of symmetrically distributed third gas nozzles 13 are provided on one side of the second end block 12, and an extended shell connected to the first end block 2 is provided on the other side of the second end block 12. An air inlet 15 connected to the second gas nozzle 4 is provided at the end of the heating rod 16, a protective mesh tube 19 is provided at the middle section of the heating rod 16, and a plurality of groups of matrix-distributed exhaust holes 14 are provided on the extended shell.

[0027] The purpose of connecting an external nebulizer inhaler is achieved by providing a third air nozzle 13, the air flow is guided to the inner cavity of the heating rod 16 by using the air inlet 15, the melting of the folded hose 11 caused by high temperature is avoided by providing a protective mesh tube 19, and circulating exhaust is achieved by using the exhaust hole 14.

[0028] Example 3: Based on Example 2, a rotatably mounted handle 17 is provided on the second end block 12, and the handle 17 is connected to the heating rod 16. A connecting inner cavity 7 connecting the first gas nozzle 3, the second gas nozzle 4 and the ventilator 1 is provided in the inner cavity of the first end block 2. The inner cavity of the second gas nozzle 4 is arranged in a stepped shape, and a spring 9 is pressed between the piston 10 and the stepped inner wall of the second gas nozzle 4.

[0029] The front end port of the second gas nozzle 4 is provided with a circular end cover 5 fixed with screws, and the circular end cover 5 is provided with symmetrically distributed opening grooves 6. The arc outer wall of the heating rod 16 is provided with a side block 20 that cooperates with the opening groove 6. After the heating rod 16 rotates, the side block 20 rotates to the inner side of the circular end cover 5 in an offset manner.

[0030] The spring 9 is provided to realize the elastic installation of the piston 10, and the turning handle 17 is used to realize the convenient rotation drive of the heating rod 16. During the insertion process of the heating rod 16, the side block 20 is first aligned with the opening groove 6 to facilitate the extension of the side block 20 into the second gas nozzle 4. Then, by rotating the heating rod 16, the side block 20 and the opening groove 6 are misaligned, thereby achieving the purpose of fixing the heating rod 16 in the second gas nozzle 4, that is, realizing the fixed installation of the second end block 12 on the first end block 2, and achieving the purpose of airflow conduction.
