Abstract
The utility model relates to the field of medical equipment, in particular to a backflow prevention Yang Kegan which comprises a first pipeline and a second pipeline, wherein interfaces between the first pipeline and the second pipeline are connected through interference fit, a cavity is formed between the first pipeline and the second pipeline, and a silica gel gasket is arranged in the cavity; when the liquid in the first pipeline flows to the second pipeline, the silica gel gasket is pushed to the second pipeline, and meanwhile, the silica gel gasket is blocked by four upright posts of the second pipeline, and the pipeline is in an unblocked state; when the liquid in the second pipeline flows into the first pipeline, the silica gel gasket is pushed to the first pipeline, and the drainage hole of the first pipeline is blocked.
Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a backflow prevention Yang Kegan.
Background
Yang Kegan is a medical apparatus for guiding pus, blood and liquid accumulated in human tissue or body cavity to outside for preventing postoperative infection and promoting wound healing. During the operation, if the waste liquid bag is accidentally squeezed or the viscera of the patient vibrate, the waste liquid can flow back, so that secondary infection is caused.
Accordingly, the present inventors have further studied this, and developed a reverse flow preventing Yang Kegan, which results therefrom.
Disclosure of Invention
The utility model aims to provide a backflow preventing Yang Kegan which can effectively reduce the retrograde infection rate and effectively prevent leakage.
In order to achieve the above object, the technical scheme of the present utility model is as follows:
a reverse flow prevention Yang Kegan, comprising
The device comprises a first pipeline and a second pipeline, wherein interfaces between the first pipeline and the second pipeline are connected through interference fit, a cavity is formed between the first pipeline and the second pipeline, and a silica gel gasket is arranged in the cavity; when the liquid in the first pipeline flows to the second pipeline, the silica gel gasket is pushed to the second pipeline, and meanwhile, the silica gel gasket is blocked by four upright posts of the second pipeline, and the pipeline is in an unblocked state; when the liquid in the second pipeline flows into the first pipeline, the silica gel gasket is pushed to the first pipeline, and the drainage hole of the first pipeline is blocked.
Further, the silica gel pad is provided with a hollow cylinder.
Further, the silica gel gasket is replaced by a duckbill valve, and the narrow mouth end of the duckbill valve is positioned in the second pipeline.
After the scheme is adopted, compared with the prior art, the utility model has the following advantages:
the normal drainage effect is realized, and meanwhile, the retrograde infection rate can be effectively reduced, and leakage can be effectively prevented.

FIG. 1 is a schematic illustration of the present utility model;
FIG. 2 is a cross-sectional view of FIG. 1;
fig. 3 is a schematic view of a silicone gasket blocked by a cylinder.
Description of the reference numerals
The first pipeline 1, the drainage hole 11,
the second pipeline 2, the upright post 21, the silica gel gasket 3 and the hollow cylinder 31.
Detailed Description
The utility model will be further described with reference to the drawings and the specific examples.
As shown in the figure, a backflow prevention Yang Kegan comprises a first pipeline 1 and a second pipeline 2, wherein liquid to be discharged flows from the first pipeline 1 to the second pipeline 2; the interface between the first pipeline 1 and the second pipeline 2 is connected through interference fit, a cavity is formed between the first pipeline 1 and the second pipeline 2, a silica gel gasket 3 is arranged in the cavity, the silica gel gasket 3 is provided with a hollow cylinder 31, and the end part of the hollow cylinder 31 points to the second pipeline 2.
When the liquid in the first pipeline 1 flows to the second pipeline 2, the silica gel gasket 3 is pushed to the second pipeline 2, and meanwhile, the silica gel gasket 3 is blocked by four upright posts 21 of the second pipeline 2, and the pipeline is in an unblocked state; when the liquid in the second pipeline 2 flows into the first pipeline 1, the silica gel gasket 3 is pushed to the first pipeline 1, and the drainage hole 11 of the first pipeline 1 is blocked.
The silica gel gasket 3 has good anti-corrosion effect, the purpose of backflow prevention is achieved by pressing the silica gel gasket 3 in the middle cavity, the sealing performance is good, and leakage is not easy to occur; the hollow cylinder 31 is additionally arranged under the gasket, so that negative pressure feedback is improved, and the reflux prevention effect is better.
The silicone gasket 3 can also be replaced by a duckbill valve, the narrow mouth end of the duckbill valve is positioned in the second pipeline 2, and when the valve is reversed, the membrane of the duckbill valve is pressed and closed, so that the reverse flow is prevented.
The foregoing is only specific embodiments of the present utility model, and words such as "upper, lower, left, right, middle" and the like "related to the present utility model are merely used by way of reference, not to be construed as limiting, and any insubstantial modifications made by the present utility model shall fall within the scope of the utility model.
