The drainage device comprises a needle, a drainage tube, a drainage treatment device and a negative pressure device, wherein the needle is arranged on the drainage tube, and a tee joint is arranged in the middle of the drainage tube; the negative pressure device is connected with the drainage treatment device; the drainage tube between the needle and the tee joint is provided with an observation tube and a drainage one-way valve; the observation tube and the drainage one-way valve are connected in series in the drainage tube; and a gas conductive one-way valve is arranged between the negative pressure device and the drainage treatment device. Compared with the prior art, the drainage device has the characteristics of reasonable design, simple structure, good draining effect and the like, and is convenient to use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of thoracic surgery drainage system.
Background technology
At present, closed drainage of thoracic cavity operation is a cardiothoracic surgery field Therapeutic Method commonly used, during treatment; Should the intrathoracic gas of patient, liquid in time be excreted, several kinds of drainage methods of prior art exist certain deficiency, and wherein a kind of is with syringe the intrathoracic gas liquid of patient to be aspirated repeatedly; The deficiency of this method is repeatedly to be punctured in patient's thoracic cavity, has increased patient's misery, and medical personnel's labor intensity is big; The suction of the intrathoracic pneumatosis of patient, hydrops is not thorough etc., and another kind of method is the thoracic drainage and thoracentesis method, and widely used clinically at present intrathoracic drain is end, side-hole-type medical silicone tube; For keeping chest drainage unobstructed, often need squeeze drainage tube, but these drainage tubes to squeeze effect bad; Can not produce bigger pressure reduction; Sludged blood and cellulose for stopping up drainage tube can not cause strong scouring effect, and the deficiency of this drainage tube is that the external fixed effect of patient is undesirable, very easily become flexible and patient's puncture place easy infection.
Summary of the invention
The technical assignment of this utility model is the deficiency to prior art, and a kind of reasonable in design, thoracic surgery drainage system that result of use is good is provided.
This utility model solves the technical scheme that its technical problem adopted:
A kind of thoracic surgery drainage system; Comprise syringe needle, drainage tube, drain processor and negative pressure device; Syringe needle is arranged on the drainage tube, and the middle part of drainage tube is provided with threeway, and negative pressure device is connected with the drain processor; Drainage tube between syringe needle and the threeway is provided with observing tube and drain check valve, and observing tube and drain check valve are connected in the drainage tube; Be provided with the inducing QI check valve between negative pressure device and the drain processor.
Said drain processor is connected through airway with negative pressure device, and the inducing QI check valve is arranged on the airway.
Said negative pressure device is provided with negative pressure switch, and said inducing QI check valve is connected with negative pressure switch.
A kind of thoracic surgery drainage system of this utility model compared with prior art, the beneficial effect that is produced is:
1) has characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, can prevent that catheter from stopping up, and can prevent that drain from refunding.
2) operation is comparatively simple, and drainage effect is good, has both reduced patient's misery, guarantees drain the carrying out that everything goes well with your work again.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model.
Among the figure: 1, syringe needle, 2, drainage tube, 3, observing tube, 4, the drain check valve, 5, threeway, 6, the drain processor, 7, the inducing QI check valve, 8, airway, 9, negative pressure switch, 10, negative pressure device.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done following the detailed description.
Shown in accompanying drawing 1; A kind of thoracic surgery drainage system of this utility model, its structure comprises syringe needle 1, drainage tube 2, drain processor 6 and negative pressure device 10, syringe needle 1 is arranged on the drainage tube 2; The middle part of drainage tube 2 is provided with threeway 5; Negative pressure device 10 is connected with drain processor 6, and the drainage tube 2 between syringe needle 1 and the threeway 5 is provided with observing tube 3 and drain check valve 4, and observing tube 3 is connected in the drainage tube 2 with drain check valve 4; Be provided with inducing QI check valve 7 between negative pressure device 10 and the drain processor 6.
Said drain processor 6 is connected through airway 8 with negative pressure device 10, and inducing QI check valve 7 is arranged on the airway 8.Negative pressure device 10 is provided with negative pressure switch 9, and said inducing QI check valve 7 is connected with negative pressure switch 9.
During drain, can observe the drain situation, because the existence of drain check valve can prevent that drain from flowing backwards through observing tube.Threeway is stretched to two with drainage tube, wherein one can do subsequent use, when drainage tube stops up therein, can be through another root drainage tube work.Open negative pressure switch, the drain processor is started working, and the inducing QI check valve can guarantee that the drain in the drain processor does not reflux, and protects from infection.
A kind of its processing and fabricating of thoracic surgery drainage system of this utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be this professional's known technology.
