Abstract
A negative -pressure drainage device, including feed liquor pipe, negative pressure pipe, bowl cover, filter screen, anti -overflow piece and pouring weight. Wherein feed liquor pipe and negative pressure pipe are fixed on the bowl cover, and the bowl cover lower extreme adopts threaded connection, convenient to detach with the cup. The filter screen is placed to the cup upper end for filter and to organize bulky objects such as thing, clot in the suction liquid. Place the anti -overflow piece under the filter screen, guarantee to prevent that filtrating flows into the negative pressure pipe because of the cup slope when liquid flows into in the cup stock solution room. Wherein there is annular bulge the cup upper end for fixed filter screen and anti -overflow piece. The pouring weight is equipped with bottom the cup for increase the whole weight of negative -pressure drainage device, prevent that negative -pressure drainage device is in the use medium dip.
Description
Technical field
This utility model is related to technical field of medical instruments, more specifically to a kind of depression drainage device.
Background technology
Negative pressure drainage device is also referred to as negative pressure suction device, and negative pressure suction device common at present mostly is disposable vacuum suction
Device.There is the problems such as negative pressure is unstable, and pressure is non-adjustable and easily causes attraction adverse current in disposable negative pressure suction device.Disease
People needs the purpose of drain, drain to gather between tissue or in body cavity in operation in surgical wounds exudate
Puss, blood or fragment of tissue etc. are directed in vitro, prevent postoperative infection and affect wound healing.Existing depression drainage device is drawing
Easily incline after stream, easily cause in cup liquid backflow, and be unable to extracting directly and go out tissue substance, doctor's later stage chemically examine need it is right again
In cup, liquid is filtered, to extract tissue substance.
Utility model content
The technical problems to be solved in the utility model：The purpose of this utility model be in order to solve it is of the prior art not
Foot, there is provided a kind of Anti-inclining, lateral leakage protection, improve work efficiency, can extracting directly tissue substance a kind of depression drainage device.
The technical solution of the utility model：A kind of depression drainage device described in the utility model, including feed tube, negative pressure
Pipe.Wherein feed tube and negative tube are fixed on bowl cover, and bowl cover lower end is connected with cup, cup upper ends filter screen, under filter screen
Anti-overflow is placed, pouring weight is housed in bottom of cup.
Further, anti-overflow is funnel-form.
Further, there is annular projection cup upper end, for fixing filter screen and anti-overflow.
This utility model beneficial effect compared with prior art：As cup upper end is fixed with filter screen, in feed tube
After liquid enters cup, the bulkrages such as tissue substance can be filtered, facilitate the later stage to chemically examine.And filter screen lower end be placed with it is anti-overflow
Piece, can prevent liquid flow into fluid reservoir after because cup flows obliquely into negative tube, cause liquid leakage.Cup base threaded connection weight
Block, increases depression drainage device overall weight, prevents depression drainage device from inclining in use.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order to deepen understanding of the present utility model, below we will combine accompanying drawing the utility model is described in further detail,
The embodiment is only used for explanation this utility model, does not constitute the restriction to this utility model protection domain.
It is as Fig. 1 shows a kind of embodiment of depression drainage device of this utility model, described in the utility model a kind of negative
Pressure drainage device, including feed tube 1, negative tube 2, bowl cover 3, filter screen 4, anti-overflow 5 and pouring weight 8.Wherein feed tube 1 and negative tube 2
It is fixed on bowl cover 3,3 lower end of bowl cover is adopted with cup 7 and is threadedly coupled, easy to disassemble.7 upper ends filter screen 4 of cup, was used for
The bulky objects such as tissue substance, clot in filtrate body.Filter screen 4 times places anti-overflow 5, prevent liquid flow into after fluid reservoir 6 because
Cup 7 is inclined, and filtrate flows into negative tube 2 and causes liquid leakage.There is annular projection wherein 7 upper end of cup, for fixing 4 He of filter screen
Anti-overflow 5.Pouring weight 8 is housed in 7 bottom of cup, for increasing depression drainage device overall weight, prevents depression drainage device from using
During incline.
Operation principle of the present utility model：In Clinical practice, pouring weight 8 is screwed in into 7 bottom of cup first, then by feed tube 1
It is connected with drainage catheter inserted into the patient, negative tube 2 connects vacuum extractor.When puss, blood or tissue in patient body
Fragment after feed tube 1 flows into cup is mingled with fragment of tissue or clot can not remain in filter screen 4 by filter screen 4 in liquid
On.Flowed in fluid reservoir 6 by anti-overflow 5 by the liquid of filter screen 4.After the completion for the treatment of that fragment of tissue is extracted, disconnect negative tube 2 with
Feed tube 1, screws off pouring weight 8.Outward winding after bowl cover 3, residue that can be on extracting directly filter screen 4 carries out medical test.
This utility model has an Anti-inclining, lateral leakage protection, improves work efficiency, can extracting directly tissue substance the characteristics of, wherein
Pouring weight can be recycled.As cup upper end is fixed with filter screen, after feed liquor liquid in pipe is entered in cup, can be big to tissue substance etc.
Volumes of matter is filtered, and facilitates the later stage to chemically examine.And filter screen lower end is placed with anti-overflow, because of cup after can preventing liquid from flowing in cup
Negative tube is flowed obliquely into, liquid leakage is caused.Cup base is threadedly coupled pouring weight, increases depression drainage device overall weight, prevents
Depression drainage device is inclined in use.
Above-mentioned specific embodiment, only illustrates technology design of the present utility model and architectural feature, it is therefore intended that allow ripe
The stakeholder for knowing technique can implement according to this, but above content is not intended to limit protection domain of the present utility model, every
Any equivalence changes made according to spirit of the present utility model or modification, all should fall into protection domain of the present utility model
Within.
