Description
Technical field
The utility model belongs to medical instruments field, and in particular to one kind has Wound-surface negative pressure treatment, tamper cleaning, wound
Face flushing and the drainage system of administration functions.
Background technology
Negative-pressure sealed drainage technology (VSD, Vaccum Sealing Drainage) is that one kind utilizes the covering of biological semi-permeable film
Polyvinyl alcohol (PVA) sponge or polyurethane (PU) sponge pass through mandruka under subnormal ambient on the surface of a wound using drainage system
Wound healing is treated.On the one hand the treatment method can deflect from wound secretion the surface of a wound, keep surface of a wound cleaning, closed
Reduce surface of a wound pollution under state and infect, under another aspect subnormal ambient, local blood circulation is accelerated, and can remarkably promote the surface of a wound new
Angiogenic is generated, so that stimulate wound granulation to organize the formation of, wound healing.
Clinically occurs sucked type negative pressure drainage device at present, this device forms uniform by negative pressure on sponge dressing
Negative pressure, wound secretion is collected at below sucker by sponge dressing, and the surface of a wound is deflected under suction function.This negative pressure drainage side
There is advantages below compared with conventional porous drainage tube in formula：Change traditional point-like drainage, increase effective drainage area；Reduce drainage stomidium
Block.Sucked type depression drainage device is divided into two classes according to whether possessing pre-washing function, as disclosed in patent 201520232496.5
A kind of medical sucked type negative pressure drainage device, the device includes sucker, negative pressure drainage conduit and connecting tube, product design letter
It is single, good airproof performance.In treatment clinical course, some surface of a wound need to be administered the surface of a wound over the course for the treatment of or unexpected stifled
Need to clear up tamper during pipe, therefore, researcher is improved device on the basis of original sucker, such as patent
201120537534.X discloses a kind of sucked type washable negative pressure drainage device, and the negative pressure drainage device is by polyvinyl alcohol, negative
The flush pipe composition of insertion is sealed on pressure sucker, drainage tube, biological dressing sticking to mould and drainage tube in circular hole, negative pressure sucker passes through
Mucous membrane be arranged on biological dressing surface, the flush pipe front portion stretch into drainage tube front end, it is necessary to when open rinse pipe plug to wound
Face carries out cleaning and the cleaning of blocked drainage tube thing.But it should be considered that in the product design, flush pipe is by being inserted in drainage tube
The circular hole being provided with carries out surface of a wound administration or flushing, and its sealing is larger to test in terms of Product processing.
In summary, disclosed negative pressure drainage device is designed in terms of sucker and had the following disadvantages：1) washing wound surface or stifled
Plug thing cleaning design aspect sealing is waited to test, and difficulty of processing is big.2) portioned product adds flush pipe design or medicine-pouring pipe design
The function such as surface of a wound cleaning and administration, tamper cleaning can be taken into account simultaneously, but there is surface of a wound administration or locally born when cleaning in product
Pressure causes the problem of air largely enters and triggers trauma surface infestation.
