Description
Technical field
This utility model relates to medical instruments field, specifically a kind of sealing of the negative pressure drainage for extremity burn wound conduction device.
Background technology
Negative-pressure sealed drainage technology (vacuum sealing drainage is called for short VSD) is that German ULM Wim doctor Fleischman of university is pioneering in 1992, and forms theoretical blank, for the drain of limb wounds; Within 1994, Chinese professor Qiu Huade is applied to department of general surgery by negative-pressure sealed drainage technology first, start the beginning of negative-pressure sealed drainage technology in department of general surgery's application, Wang Yanfeng, Qiu Huade professor in authorized patent CN2276350 on March 18th, 1998, is first patent of negative-pressure sealed drainage technology in China.From then on, negative-pressure sealed drainage technology has obtained larger development in China.
Negative-pressure sealed drainage technology realizes by negative-pressure sealed drainage system, and it comprises that porous foam cushion, one end are arranged on drainage tube in porous foam cushion, sealing film for sealing porous airfoam cushion.The porous foam cushion of assembling drainage tube is laid on wound surface, with sealing film sealing, and drainage tube is connected to negative pressure, thereby set up the drain district of a sealing at wound surface place, carry out negative-pressure sealed drainage constantly.
Compared with existing common changing dressings, negative-pressure sealed drainage technology can will be removed by porous foam cushion and drainage tube at the right time by the exudate in drain district and slough, thereby make can be reached by drain district " nil product is poly-" state, wound surface can be under lasting cleaning ambient, greatly reduces the heavily absorption of body contratoxin; Even if there is larger lacuna to exist, lacuna is also because the existence of negative pressure is accelerated to dwindle.For shallow table wound surface, sealing film and porous foam cushion also make local environment more approach physiological moisture state; Meanwhile, the negative pressure acting on wound surface soft tissue stimulates, and is conducive to the improvement of local microenvironment and disappearing of tissue edema, has accelerated the new life of granulation tissue in wound surface, shortens wound healing time.Under negative-pressure sealed drainage technology treatment, without changing dressings, reduce medical worker's workload in wound surface 3-7 days, reduce patient suffering, reduce general practice expense.
In China, negative-pressure sealed drainage technology is widely used in: the fields such as traumatology department, orthopaedics, department of general surgery, Department of B urn.
At present the negative-pressure sealed drainage product on domestic and international market, is generally made up of negative-pressure sealed material, sealing pad pasting, wound drainage pipe.In use, first need according to wound area size, negative-pressure sealed material is carried out to cutting to be adapted to wound scope, then negative-pressure sealed material is covered on wound, then seal with sealing pad pasting thereon, and draw wound drainage pipe.
For general smooth, little wound surface, cutting, flap coverage sealing, whole negative pressure operation probably need to spend the time of a skilled surgical doctor about 10 minutes; But for larger wound surface, or more complicated, irregular wound surface, need doctor, according to practical situation, negative-pressure sealed material is carried out to cutting, combination, and need polylith to seal pad pasting combination sealing, the for example covering of limb wound sealing, often needs 1 hour above operating time of doctor.
According to the clinical practice of domestic hospitals, in irregular wound surface, the most general with extremity burn wound, and be often difficult to sealing: area is large, wound surface extremely irregular (shape of hands or foot, the flexibility of arm).Once but the extremity of occurrence of large-area burn, the large-area burns that for example all kinds of fire, war, various natural disaster cause, needs of patients starts negative pressure treatment in the shortest time, and operation technique for a long time can have a strong impact on the finally effect for the treatment of of patient.
Summary of the invention
The purpose of this utility model is a kind of sealing of the negative pressure drainage for extremity burn wound of design conduction device, and medical personnel can carry out negative pressure surgical procedure to limb wound easily, save operating time, promote medical care efficiency, improve patient's therapeutic quality.
The technical solution of the utility model: the sealing of the negative pressure drainage for extremity burn wound conduction device of the present utility model comprises porous foam negative pressure conducting shell, diaphragm seal, backing film from inside to outside, the two ends of its diaphragm seal and backing film and a side have parcel with extending bound edge, be diaphragm seal end bound edge and backing film end bound edge and diaphragm seal side bound edge and backing film side bound edge, have end release paper and side release paper in the outside of diaphragm seal end bound edge and diaphragm seal side bound edge.
In end release paper and side release paper, there is size marking
Advantage of the present utility model: this utility model forms integrated structure by porous foam negative pressure conducting shell by medical pad pasting, diaphragm seal, backing film, pad pasting negative pressure conducting shell is slightly large, for enclosed dressing is covered after limbs, the sealing of sewing up position is pasted.Enclosed dressing can cutting, to be adapted to the arm of all ages and classes, different size.Size marking is used in reference to guiding doctor teacher's cutting.
