Description
Technical field
The utility model relates to medical instruments fields, are applied in various shield invasive procedures, specifically a kind of no impression,
Realize that the built-in type of continuous drainage rinses negative pressure closed drainage device comprehensively.
Background technique
Negative-pressure sealed drainage technology (vacuum sealing drainage, abbreviation VSD) is 1992, German ULM university
Doctor Fleischman starts utility model, and preliminarily forms theoretical blank by clinical verification, for the wound in surgical operation
Mouth surface of a wound drainage；It is introduced by Guangzhou professor Qiu Huade within 1994, and negative-pressure sealed drainage technology is applied to department of general surgery's hand for the first time
In art, since this negative-pressure sealed drainage technology Chinese medical department of general surgery practical application.On March 18th, 1998, Wang Yanfeng, fur coat
The Hua De professor utility model patent CN 2276350 authorized in China, negative-pressure sealed drainage technology start in each of China
Large hospital is promoted, while various medical companies relevant to negative-pressure sealed drainage technology, medical device product emerge one after another.
To 2018, negative-pressure sealed drainage technology obtained biggish development in the application of global wound surface, the exclusive letter of the technology
Just property, reliability and therapeutic effect have obtained the approval always of medical staff and have approved of.
Negative-pressure sealed drainage technology is realized by negative-pressure sealed drainage system, it mainly includes porous foam, draws
Flow device and the sealing film for sealing porous foam.Porous foam is laid on the surface of a wound, is sealed with medical sealing film,
By drainage device connection porous foam and negative pressure source, so that the closing drainage area outside an isolation is established at the surface of a wound,
System is set to carry out constantly negative-pressure sealed drainage.This technology is compared with existing common dressing change means, can draw the surface of a wound
Exudate and necrotic tissue in stream area are removed in good time by porous foam and drainage device, make surface of a wound drainage area approach
In realization " nil product is poly- " state, the surface of a wound is at long-term cleaning ambient with this condition, greatly reduces body to nocuousness
The double absorption of substance, at the same the presence of negative pressure can also make biggish lacuna at the surface of a wound because negative pressure there are due to accelerate to reduce.
Porous foam used in negative-pressure sealed drainage technology and medical sealing film can also make the local microenvironment of the surface of a wound closer
The moisture state of physiological, and the stimulation of the negative pressure on surface of a wound soft tissue is acted on, be conducive to improve surface of a wound local microenvironment and group
The recession of oedema is knitted, regrowing for wound granulation tissue is accelerated, shortens wound healing treatment time.Negative-pressure sealed drainage simultaneously
Technology treatment can make to substantially reduce the workload of medical worker without dressing in the surface of a wound 3-7 days, reduce patient suffering, promoted
The experience sense of patient's treatment, reduces the general practice expense of sufferer.
Negative-pressure sealed drainage technology has been widely used in China at present: the wound such as Department of traumatology, orthopaedics, department of general surgery, Department of B urn
Face trauma care field.But it is born by the product of each company currently on the market clinically using treating, being found in operation
It presses drainage device unreasonable due to designing, often will appear pressure leakages, drains the disadvantages of unusual, flushing effect is not good enough, doctor
Shield personnel need the operation of long period, and the closed negative pressure state of ability realization device realizes the function of product.To in clinic
On be presented as, design it is not perfect cause operation irrationality, increase the clinical position time of medical staff, be exaggerated operation
Successful relative risk, while being unfavorable for the efficient progress of operation.
In the market the medical instrument using negative-pressure sealed drainage technology of mainstream there are two main classes composition, one kind is with poly- second
The system of enol foam and built-in drainage tube composition, one kind is the system formed with polyurethane foam and external sucker.Polyethylene
When drainage tube body built in alcohol foam ties up to clinical use, medical sealing film is complicated for operation, needs training and length by profession
The practical operation experience of time just can effectively solve the various problems occurred in clinical application；Built-in drainage tube is negative simultaneously
Under the action of pressure, the compressing of certain power is carried out to the surface of a wound, and the white trace of one of drainage tube, the use of patient are left on the surface of a wound
Family embodiment sense has to be hoisted；And flushing pipeline depends on drainage pipe, can only realize in pipeline and rinse, and can not achieve medical care
Washing wound surface desired by personnel.When the external sucker of polyurethane foam ties up to clinical use, although being operated in medical sealing film
It goes up relatively simple and there is no impression, but the drainage effect of sucker is poor compared with built-in drainage tube, and flushing pipeline depends on sucker,
It can only realize in sucker and sucker pipeline and rinse, can not achieve washing wound surface.
