The utility model provides a closed negative pressure draining device, simple structure, convenient to use can avoid the infection problem that drainage liquid refluence caused.
Description
Technical field
The utility model relates to medical auxiliary equipment technical field, particularly a kind of closed negative pressure drainageDevice.
Background technology
Negative pressure ball has drainage mouth hematocele, estimates blood volume, prevents to infect, promote the effects such as healing,Be widely used in the postoperative patients such as orthopaedics, neurosurgery, thoracic surgery, the patient who places negative pressure ball is being enteredWhen row nursing, regularly topple over drainage-fluid, record drainage-fluid character, drainage flow, keep drainage unobstructed,Therefore, the designing requirement of negative pressure ball is easy to carry about with one, conveniently topples over, and negative pressure ball mostly is class ellipse, has twoIndividual opening, connects respectively wound drainage pipe and topples over drainage tube, current negative pressure ball drainage system drainage-fluidAmount statistics inaccuracy, do not there is the function of anti-backflow, many drawbacks such as contaminated environment while toppling over, this realityWith therefore novel.
Summary of the invention
In order to solve the problem of prior art, the utility model object is to provide a kind of closed negative pressure drainageDevice, it is simple in structure, easy to use, and drainage flow statistics accurately, prevents retrograde infection and contaminated environment.
Based on the problems referred to above, the technical scheme that the utility model provides is:
Closed negative pressure drainage device, comprises negative pressure ball, and the two ends of described negative pressure ball are respectively equipped with entrance and connectConnect portion and outlet connecting portion, described entrance connecting portion with on described outlet connecting portion, be connected respectively drainage-fluid and enterPipe and drainage-fluid go out pipe, and described outlet connecting portion is provided with the exhaust outlet that is connected to depression generator, instituteState drainage-fluid and enter pipe and be positioned on described entrance connecting portion check valve is set, described drainage-fluid goes out pipe and is connected to storageLiquid bag.
Further, the inwall of described negative pressure ball is provided with elastic steel traveler.
Further, described negative pressure ball adopts transparent material to make, and the outer wall of described negative pressure ball is provided with quarterDegree line.
Further, the upper end of described negative pressure ball is provided with handle.
Compared with prior art, the utility model has the advantages that:
1, adopt the technical solution of the utility model, this gathering-device is simple in structure, for postoperative woundThe drainage of hydrops, easy to use, can prevent that drainage-fluid from flowing backward to wound, avoid occurring retrograde infection, protectCard curative effect;
2, adopt the further technical scheme of the utility model, at the inwall of negative pressure ball, elastic wire is setCircle, makes the negative pressure ball can bearing certain pressure, not yielding, ensures the normal work of negative pressure ball;
3, adopt the further technical scheme of the utility model, on negative pressure ball outer wall, graduation mark be set,Nursing staff can estimate according to this graduation mark the amount of drainage-fluid, the convenient state of an illness that judges patient.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, will describe embodiment belowIn the accompanying drawing of required use be briefly described, the accompanying drawing in the following describes is only of the present utility modelSome embodiment, for those of ordinary skill in the art, are not paying under the prerequisite of creative work,Can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model closed negative pressure drainage device embodiment;
Wherein:
1, negative pressure ball; 11, entrance connecting portion; 12, outlet connecting portion; 13, exhaust outlet;
2, drainage-fluid enters pipe;
3, drainage tube goes out pipe;

Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further. Should be understood that these embodiment areBe used for the utility model is described and be not limited to limit scope of the present utility model. The enforcement adopting in embodimentCondition can be done further adjustment according to the condition of concrete producer, and it is conventional that not marked implementation condition is generallyCondition in experiment.
Referring to Fig. 1, be the structural representation of the utility model embodiment, provide a kind of enclosed negative pressure to drawStream device, comprises negative pressure ball 1, is respectively equipped with entrance connecting portion 11 and outlet at the two ends of negative pressure ball 1Connecting portion 12, is connected respectively drainage-fluid on connecting portion 12 in entrance connecting portion 11 and outlet and enters pipe 2 HesDrainage-fluid goes out pipe 3, on outlet connecting portion 11, is provided with the exhaust outlet 13 that is connected to depression generator,Drainage-fluid enters pipe 2 and causes patient's wound, and drainage-fluid goes out pipe 3 and is connected to liquid storing bag 4, in order to prevent drainageLiquid flows backward to patient's wound, enters pipe 2 be positioned at check valve 5 is set on entrance connecting portion 11 at drainage-fluid.
On the inwall of negative pressure ball 1, be provided with elastic steel traveler 6, can make negative pressure ball 1 when gripping negative pressure ball 1Can bearing certain pressure, prevent that negative pressure ball 1 is out of shape, ensure the normal work of negative pressure ball 1.
In this example, negative pressure ball 1 adopts transparent material to make, and is provided with quarter on the outer wall of negative pressure ball 1 simultaneouslyDegree line 7, the amount that nursing staff can observe drainage-fluid according to this graduation mark 7, and in time drainage-fluid is discharged.
Be provided with handle 8 in the upper end of negative pressure ball 1, the negative pressure ball 1 of taking when negative pressure drainage device easy to use.
Above-mentioned example is only explanation technical conceive of the present utility model and feature, and its object is to allow is familiar with thisThe personnel of item technology can understand content of the present utility model and implement according to this, can not limit this reality with thisWith novel protection domain. All equivalent transformations doing according to the utility model Spirit Essence or modification, allWithin should being encompassed in protection domain of the present utility model.
