Abstract
The invention relates to a medical circulating negative pressure drainage device which comprises a liquid input pipe, a wound surface contact sponge, a drainage contact sponge, a wound surface closing membrane, a drainage pipe, a collector, a medical three-way valve, a bacteria removing device, a peristaltic pump and the like. Liquid such as wound surface exudate and/or medicine and the like is driven by the peristaltic pump to flow in the whole device in a circulating way, and the bacteria removing device is used for continuously removing bacteria in the circulating liquid. The negative pressure drainage device can ensure a wound surface to be closed and avoids the wound surface being infected; and the device also reduces the loss of liquid content when fully draining, has simple structure and convenient operation and use, and lightens the work load of medical care personnel.
Description
Technical field
The present invention relates to a kind of medical circulating negative pressure drainage device, especially can run off simultaneously, continue to remove the medical apparatus and instruments that the wound surface microorganism also can take into account wound surface flushing and medicinal application at the minimizing wound exudate.
Background technology
The large area skin wound surface can't heal usually in a short time voluntarily, the wound surface infection that often occurs together, in medical treatment and nursing at present common way be to wound surface carry out fully, drain timely.Though the fully drain of existing all kinds of closed negative pressure drainage devices causes wound exudate to run off in a large number, reduces patient's effective circulating blood volume, or make the patient in various degree negative nitrogen balance occur.In addition, after closed negative pressure drainage used a period of time, drainage speed slowed down (wound fluid reduces and or drainage tube obstruction gradually), and antibacterial is prone to a large amount of breedings in the wound surface enclosed environment.At this moment, will have to change closed negative pressure drainage device.
Summary of the invention
In order to overcome the deficiency that existing closed negative pressure drainage device quickens the wound exudate loss and must regularly replace, the invention provides the wound surface drainage system of a cover circulation degerming, this device can not only reduce the loss of wound exudate, and can continue to remove the wound surface microorganism and make things convenient for all kinds of liquid medicines to directly apply to wound surface.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the present invention is contacting in the sponge with wound surface, has adopted and the different aperture design of drainage tube contact sponge, and has kept somewhere liquid input tube therein.The aperture of wound surface contact sponge is bigger, is convenient to the liquid input; Drain contact sponge aperture is less, can prevent that drainage tube chamber from blocking.Drainage tube one end is connected with drain contact sponge, the other end connects the catcher top and collects mouth, the catcher outlet at bottom connects antibacterial scavenge unit input by a medical three-way valve, antibacterial scavenge unit outfan links to each other with liquid input tube, form the blood circulation of a relative closure like this, catcher connects negative pressure suction device by top negative pressure connector, make in the catcher to keep-100 to-200mmHg negative pressure, guarantee that drainage tube can constant drainage and keep the wound surface sealing.Connect the hose overcoat peristaltic pump, peristaltic pump provides power that the interior liquid circulation of pipeline is flowed, and the wound surface microorganism is constantly taken away and is removed in the antibacterial scavenge unit.By medical three-way valve, wound fluid can be extracted and carry out drug sensitive test, also can apply sensitive antibiotic, wound surface disinfectant solution, flushing liquor (normal saline, balanced salt) to wound surface.
The invention has the beneficial effects as follows, can keep the microorganism of the lasting simultaneously removing wound surface of wound exudate, and can take into account wound surface flushing and medicinal application.Can use continuously for a long time, reduce medical personnel's workload, alleviate the patient cost burden.
Description of drawings
Fig. 1 is an assembly exploded view of the present invention.
Fig. 2 implements sketch map.
The specific embodiment
1. wound surface contact sponge, 2. drain contact sponge, 3. liquid input tube among Fig. 1,4. catcher, 5. antibacterial scavenge unit, 6. medical three-way valve, 7. peristaltic pump, 8. collect mouthful at the catcher top, 9. the catcher outlet at bottom, 10. antibacterial scavenge unit input, 11. antibacterial scavenge unit outfan, 12. closing membranes, 13. connect flexible pipe, 14. drainage tube, 15. catcher top negative pressure connectors.
In Fig. 2, wound surface contact sponge 1, sponge 2 closely contacts in the drain contact, and by closing membrane 12 coverings, connect liquid input tube 3 in the wound surface contact sponge 1, drain contact sponge 2 is by drainage tube 14, connect catcher 4 tops and collect mouth 8, catcher outlet at bottom 9 connects antibacterial scavenge unit input 10 by a medical three-way valve 6, antibacterial scavenge unit outfan 11 links to each other by the liquid input tube 3 that connection flexible pipe 13 contacts with wound surface again in the sponge 1, form a circulation system like this, connect peristaltic pump 7 of flexible pipe 13 overcoats, catcher is by top negative pressure connector 15, connect negative pressure suction device, make in the catcher to keep-100 to-200mmHg negative pressure; Guarantee drainage tube energy constant drainage wound surface liquid and keep the wound surface sealing.7 of peristaltic pumps constantly provide circulation power.Because there is lasting flowing liquid, the unobstructed property of drain is improved in the sponge; The intravital antibacterial of circulation fluid can be removed by antibacterial scavenge unit 5, and the device anti-infection property also is improved.By medical three-way valve 6, wound fluid can be extracted and carry out drug sensitive test, also can apply sensitive antibiotic, wound surface disinfectant solution, flushing liquor (normal saline, balanced salt) to wound surface, the various treatment operations of being more convenient for.
Claims (3)
1. a medical circulating negative pressure drainage device is connected by liquid input tube, wound surface contact sponge, drain contact sponge, wound surface closing membrane, drainage tube, catcher, medical three-way valve, antibacterial scavenge unit, liquid input tube circular order, it is characterized in that: liquid such as planing surface transudate and/or medicine, contact the sponge internal recycle by the peristaltic pump driving with drain in wound surface contact sponge and flow the antibacterial in the sustainable removing circulating fluid of antibacterial scavenge unit.
2. medical circulating negative pressure drainage device according to claim 1 is characterized in that: isolated by two kinds of aperture sponges between liquid input tube and the drainage tube, liquid is driven persistent movement in the liquid input tube by peristaltic pump.
