Description

A kind of negative pressure closed drainage device

Technical field

This utility model relates to technical field of medical instruments, particularly, relates to a kind of negative pressure closed drainage device.

Background technology

Negative-pressure sealed drainage technology (VSD) refers to the polyethylene ethanol aquation Sargassum salt foam dressing (VSD adjuvant) that contains drainage tube, cover or fill the wound surface of skin, soft tissue defects, with biological semipermeable membrane, it is sealed again, become a confined space, finally drainage tube is connected to negative pressure source, by controllable negative pressure, carry out a kind of brand-new Therapeutic Method of wound healing.

Implement the required material of VSD and comprise 1, medical foam: be the part of directly inserting by drain district, it is a kind of foam type polyethylene ethanol aquation Sargassum salt foam dressing (PVA foam), color is white, cavernous transformation, the soft high resilience of quality, tension stress is strong, the space of the densely covered diameter 0.2～1.0mm communicating with each other in a large number in it, there are fabulous plasticity and water penetration and good biocompatibility 2, drainage tube: many side openings conductions pipe: many side openings of CH14-18 hard gel drainage tube that German B.Braun company produces, long 50cm, within the scope of the 14cm of its one end, there is intensive side opening, during drain, many side openings conductions pipe is penetrated in medical foam, the existing medical foam supply that has penetrated many side openings conductions of CH-18 pipe, easy to use.3, saturating property sticking film: the transparent dressing that Minnesota Mining and Manufacturing Company produces, its composition, for poly-peace fat, is that a kind of saturating property with molecule valve function is pasted thin film, finished product is contained in aseptic plastic bag, for disposable.In order to sealing, by drain region, made to be hedged off from the outer world; 4, negative pressure source: drain power is provided, guarantees by drain district planted agent drawing by derivated.

The feature of VSD is: 1) controllable negative pressure, promote that blood flow growth and albumen are synthetic, and promote granulation growth, accelerate wound healing; Simultaneously for omnibearing active drain provides power.2) sealing of biological semipermeable membrane, has completely cut off the infection chance that wound surface contacts with external environment.3) omnibearing drain, is by traditional point-like or local drainage, has become planar drain, has guaranteed at any time by the slough of the everywhere of wound surface and transudate, to get rid of in time external.

Use the advantage of VSD as follows: 1) treatment time obviously shortens, reduce patient painful, and alleviate workload.Patient exempts the hardship of changing dressings, and doctor exempts the labor of changing dressings.2) effectively avoid cross infection VSD to carry out in an airtight system, negative pressure drainage is removed the exudate in drain district and slough in time, 3) efficient, comprehensive, nil product is gathered, guarantee that drainage effect promotes wound surface blood fortune to adopt the method for continuous negative pressure suction, becoming passive drain initiatively attracts into continuing, do not stay any lacuna, the height of its pressure meets the requirement of physiological condition substantially, therefore do not affect blood fortune.The more important thing is, continuous negative pressure suction has promoted the body fluid of wound tissue constantly to flow to drainage tube direction, for the blood of wound surface, transports effective, that continue, auxiliary power is provided.4) avoid dead.

In China, VSD technology is widely used in: the fields such as traumatology department, Department of B urn, department of general surgery, orthopaedics.

But, as easy as rolling off a logly in VSD utilization process cause drain to stop up, trace it to its cause into: 1, by the too much or a large amount of thickness derivated of the slough in drain region, exceed the disposal ability of drainage tube.2, sealing film is poorly sealed, causes the forfeiture of subnormal ambient, and the liquid in drainage tube or granule can not be attracted and suction drainage container, and in drainage tube, solidifies one section of dry derivated obstruction drainage tube of formation.3, sealing film is poorly sealed, makes porous foam cushion dealcoholysis hardening, causes porous foam cushion to lose drainage.4, wound surface cleaning not exclusively, as not hemostasis etc. completely.

In order to solve the problems of the technologies described above, Chinese patent literature CN201529311U discloses the airfoam cushion structure of the built-in drainage tube with syringe pipe.This patent is at a built-in sidewall in drainage tube with the syringe pipe of side opening, and syringe pipe passes the rear end tube wall of drainage tube and draws.

This patent documentation CN201529311U has no doubt solved the problem of a part of blocked drainage tube, yet, utilize water to rinse the drainage tube stopping up, flushing dynamics is inadequate, not only can not solve the problem of obstruction, and flushing liquor also can leak into wound face, causes superinfection.In addition, when stopping up frequent generation, need to frequently rinse, flushing liquor is used too much, and unfavorable wound face keeps dry.

Utility model content
