Description
Technical field
This utility model relates to medical devices technical field, relates in particular to the drainage system that a kind of sustainable negative pressure generates.
Background technology
Drainage system is mainly used in the postoperative drain of puncturing to thoracic cavity, abdominal cavity patient.Current drainage system comprises sacculus, and the top of sacculus is combined with seal cover, and seal cover is provided with feed liquor interface and the air vent communicating with sacculus, is provided with feed liquor check valve in feed liquor interface, and air vent is provided with gag.The bottom of sacculus is provided with discharge opeing outlet, and discharge opeing outlet is connected to drainage bag by drainage tube, and drainage tube is provided with pipe clamp.
During use, unplug gag, with pipe clamp, clamp drainage tube, can push sacculus and carry out aerofluxus, after sacculus aerofluxus gag on air vent, after loosing one's grip, formation negative pressure in sacculus, can carry out drain.But while pushing sacculus, all to clamp drainage tube with pipe clamp at every turn, and all need gag to unplug at every turn, after forming negative pressure in sacculus again, also need pipe clamp to unclamp and gag beyond the Great Wall, thereby operation is inconvenient at every turn, can not continuously extruded sacculus, and can not form continuous negative pressure.
Utility model content
The purpose of this utility model is to provide the drainage system that a kind of sustainable negative pressure generates, easy to operate, can continuously extruded sacculus and the continuous negative pressure that forms.
For achieving the above object, the drainage system that this utility model provides a kind of sustainable negative pressure to generate, comprise sacculus, described sacculus top is combined with a seal cover, described seal cover is provided with a feed liquor interface and the air vent communicating with sacculus, in described feed liquor interface, be provided with a feed liquor check valve, on described air vent, cover has a gag band, described gag band is provided with a gag that can mate with described air vent, described sacculus bottom is provided with a discharge opeing outlet, described discharge opeing outlet is connected to a drainage bag by a discharging tube, on described discharging tube, be equipped with a pipe clamp, in described air vent, be provided with the outgassing nonreturn valve of the conducting of giving vent to anger.
Owing to being provided with the outgassing nonreturn valve of the conducting of giving vent to anger in air vent, the outgassing nonreturn valve of conducting of giving vent to anger can avoid sacculus extraneous air to enter in sacculus, thereby do not need frequently to draw the cork lid and capping plug cover, easy to operate, and can one-handed performance, can continuously extruded sacculus and form continuous negative pressure.
As further improvement of the utility model, in described discharge opeing outlet, be provided with the ball valve of a fluid conducting.Because the ball valve of fluid conducting also can be avoided the discharge opeing outlet of sacculus bottom and enters air, thereby do not need frequently to use pipe clamp clamp or unclamp discharging tube, further make more convenient to operate.
As of the present utility model, further improve, described sacculus outer wall is provided with gage mark.Adopt gage mark can further facilitate the operation of sacculus.
As of the present utility model, further improve, the position that described gag band is enclosed within on air vent is also connected with and is linked with.Employing is linked with and can conveniently sacculus be hung up, thereby further facilitates the operation of sacculus.
By following description also by reference to the accompanying drawings, it is more clear that this utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the drainage system of the sustainable negative pressure generation in this utility model.
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1-2, the drainage system that described sustainable negative pressure generates comprises sacculus 1, and described sacculus 1 top is combined with a seal cover 2.Described seal cover 2 is provided with a feed liquor interface 3 and the air vent 4 communicating with sacculus 1, in described feed liquor interface 3, be provided with a feed liquor check valve 5, on described air vent 4, cover has a gag band 6, described gag band 6 to be provided with a gag 7 that can mate with described air vent 4.Described sacculus 1 bottom is provided with a discharge opeing outlet 8, and described discharge opeing outlet 8 is connected to a drainage bag (not shown) by a discharging tube 9.On described discharging tube 9, be equipped with a pipe clamp 10, in described air vent 4, be provided with the outgassing nonreturn valve 11 of the conducting of giving vent to anger.
Further illustrate, in described discharge opeing outlet 8, be also provided with the ball valve 12 of a fluid conducting.Described sacculus 1 outer wall is provided with gage mark 13.The position that described gag band 6 is enclosed within on air vent 4 is also connected with and is linked with 14, thereby conveniently hangs sacculus 1, be linked with 14 with gag band 6 one-body molded, thereby saved production cost.
During use, unplug described gag 7, can push sacculus 1 and carry out aerofluxus, after loosing one's grip, in sacculus 1, just form negative pressure, can carry out drain by feed liquor interface 3, discharge opeing outlet 8 and discharging tube 9, during drain, the steel ball of ball valve 12 is in the lower end of ball valve 12.Owing to being provided with the outgassing nonreturn valve 11 of the conducting of giving vent to anger in air vent 4, outgassing nonreturn valve 11 is cone shaped one-way valve, when extruding sacculus 1, outgassing nonreturn valve 11 one-way conductions, when discharging sacculus 1, the air of sacculus 1 outside can not enter in sacculus 1 by outgassing nonreturn valve 11, and owing to being also provided with the ball valve 12 of fluid conducting in discharge opeing outlet 8, when extruding sacculus 1, the steel ball of ball valve 12 is in the lower end of ball valve 12, and while discharging sacculus, the steel ball of ball valve 12 can up move the outlet of blocking ball valve 12, thereby the air of sacculus 1 outside can not export 8 from discharge opeing and enter in sacculus 1, thereby can avoid frequently drawing the cork, cover 7 and capping plug lid 7 and frequently use pipe clamp 10 to clamp or unclamp discharging tube 9, operation is more simple and convenient compared to existing technology, and can continuously extruded sacculus and form continuously negative pressure, can also one-handed performance.Can be not after sacculus 1 aerofluxus gag 7 on air vent 4, it is to avoid air vent 4 contaminated in order to make that gag 7 covers on air vent 4, makes sacculus 1 health more.
Above combination most preferred embodiment is described this utility model, but this utility model is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
