But adopt the reason of single lumen catheter drain owing to VSD; Make VSD technology and various modification method thereof have some limitation: (1) is because the dehydration characteristic of fine vacuum; When wound exudate not for a long time, the sepage in the drainage tube is flowed slowly, the dehydrated dry and hard accumulation in back of solids; Cause drainage tube to stop up through regular meeting, treatment was lost efficacy; Vacuum also can make the foam material for medical use dehydration dry and hard, and treatment was lost efficacy, and above phenomenon has greatly reduced the reliability and its therapeutic effect of VSD technology.(2) when wound surface has more pus or downright bad material, the medical foam body will soon be by contaminated, and the drain on the foams is stopped up with micropore, and drain and treatment were lost efficacy; During (3) because of the treatment of VSD technology, patient's wound surface is sealed, so in the process of treatment, generally can not adjust local application according to the situation of wound surface, treatment means is more single, influences therapeutic effect.When above-mentioned various situation occurring,, all greatly increased medical personnel's workload and medical treatment cost no matter be to change drain dressing or long-term observation and nursing.
Summary of the invention
For overcoming the defective of prior art; This utility model provides a kind of negative pressure drainage device with washing capacity; The medical foam soma knot that exists with the solution prior art causes drain to be stopped up with micropore, and treatment was lost efficacy, and can not wash the phenomenon with vacuum suction simultaneously.The technical scheme of this utility model is: a kind of negative pressure drainage device with washing capacity; Comprise conduit and the drainage tube that is installed in the conduit bottom; The periphery of the bottom of said drainage tube is provided with side opening; And insert in the medical foam body, it is characterized in that: also comprise first syringe pipe and second syringe pipe.
Described first syringe pipe is arranged on the inside of drainage tube, and its top and bottom all pass drainage tube, and with exterior, the lower end of said first syringe pipe offers several first through holes.
Described first syringe pipe is arranged on the outside of drainage tube, and its lower end offers several first through holes, and bonds together with drainage tube.
The said first syringe pipe lower end pass or do not pass the medical foam body.
Described second syringe pipe is arranged on the drainage tube, and the one of which end and communicates the other end and exterior with drainage tube on the sidewall of drainage tube.
Described second syringe pipe is arranged on the drainage tube, and the periphery of one of which end offers several second through holes, stretches to the inside of drainage tube and extends to bottom, the other end and the exterior of drainage tube.
The dosing kettle is installed between described conduit and the drainage tube, and described dosing kettle comprises upper kettle body and lower kettle body, and described upper and lower kettle body by integral forming is perhaps through being threaded together.
Dosing kettle and exterior are passed in the upper end of described first syringe pipe.
Described second syringe pipe is arranged on the dosing kettle, and the periphery of one of which end offers several second through holes, stretches to the inside of drainage tube and extends to bottom, the other end and the exterior of drainage tube.
Described second syringe pipe is arranged on the dosing kettle, and the one of which end and communicates the other end and exterior with the dosing kettle on the sidewall of dosing kettle.
Described drainage tube is socketed in the bottom of lower kettle body, the co-axial periphery that is arranged on drainage tube of described second syringe pipe, and one of which end and exterior, the other end extends in the medical foam body; One end of described first syringe pipe penetrates dosing kettle and drainage tube, and passes to the outside other end and exterior from the sidewall of drainage tube bottom.
The utility model has the advantages that: simple to operate, easy to use, except drainage tube, also be provided with first syringe pipe and second syringe pipe, guaranteed drainage tube, the cleaning of medical foam body and the flushing of wound, can also carry out vacuum suction simultaneously.
