Description

Technical Field

[0001] The utility model relates to a device for eliminating hydraulic positive water hammer effect generated by a suction device connecting pipe in negative pressure suction in the medical field, more specifically a negative pressure suction device connecting transition piece. Background Art

[0002] When using a negative pressure aspirator, a connecting tube must be used at the same time. Currently, when encountering blood clots, colloids and a large number of pus plugs during negative pressure aspiration, the pipeline is prone to sudden blockage. Due to inertia, the water behind continues to move forward, forming a water shock wave, and in a continuous suction state, the aspirator connecting tube and the water collection device are detached, forcing the operation process to be interrupted and easily causing pollution. Therefore, a negative pressure aspirator connection transition piece is designed. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a negative pressure aspirator connection transition piece, which can provide a water hammer effect caused by the negative pressure process.

The hydraulic principle is used to eliminate the positive water hammer effect of a high probability event during the use of negative pressure suction, reduce the interruption time of negative pressure operation, reduce dirt pollution, improve work efficiency, and has a wide range of applications.

[0016] Example:

[0017] Combine the following Figure 1-2 To describe this embodiment, the utility model relates to a device for eliminating the hydraulic positive water hammer effect generated by the use of an aspirator connecting tube in negative pressure suction in the medical field, and more specifically, to a negative pressure aspirator connecting transition piece, including an inlet 1 and an outlet 4, characterized in that: a first connecting tube 2 and a second connecting tube 3 are provided between the inlet 1 and the outlet 4, the first connecting tube 2 and the second connecting tube 3 are connected in parallel, and the first connecting tube 2 and the second connecting tube 3 are symmetrically distributed between the inlet 1 and the outlet 4, which can provide a device capable of eliminating the water hammer effect caused by the negative pressure process.

[0018] The inner diameters of the first connecting pipe 2 and the second connecting pipe 3 are larger than the inner diameters of the inlet 1 and the outlet 4, so that the first connecting pipe 2 and the second connecting pipe 3 are not easily blocked.

[0019] The first connecting pipe 2 and the second connecting pipe 3 have the same inner diameter, so as to evenly distribute the fluid at the inlet.

[0020] The first connecting pipe 2 and the second connecting pipe 3 are V-shaped. Figure 1 As shown, easy to observe.

[0021] The first connecting pipe 2 and the second connecting pipe 3 are made of transparent materials for easy observation.

[0022] The first connecting tube 2 and the second connecting tube 3 form a "◇" shape. The double-channel structure of the "◇"-shaped tube can disperse the pressure and also give the blocked part space and time to process without affecting the operation.

[0023] Usage process: turn on the negative pressure, install the disposable suction bottle and the connecting tube to operate. When encountering blood clots, colloids and a large number of pus plugs during operation, the above situation may cause the pipeline to be suddenly blocked, causing the suction connecting tube to come out of the water collection device. The double-channel structure of the "◇"-shaped tube can disperse the pressure and provide space and time for the blocked part to be treated without affecting the operation.

[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
