Description
Technical field
This utility model relates to medical instruments field, is applied to protect in invasive procedures, a kind of efficient operation
Negative pressure closed drainage device.
Background technology
Negative-pressure sealed drainage technology (vacuum sealing drainage is called for short VSD) is ULM university of Germany
Doctor Fleischman initiated in 1992, and formed theoretical blank, for the drain of wound surface；Qiu Huade professor in 1994
First negative-pressure sealed drainage technology is applied to department of general surgery in Guangzhou, starts negative-pressure sealed drainage technology outside Chinese medical is general
The beginning of section's application, is taught in China in authorized patent CN on March 18th, 1998 by Wang Yanfeng, Qiu Huade subsequently
2276350, this patent is first patent of negative-pressure sealed drainage treatment wound surface technology.From then on by 2015,
Negative-pressure sealed drainage technology has obtained bigger development in China's treatment wound surface application, according to market preliminary survey,
In national wound surface in 2015, the output value of negative-pressure sealed drainage product is about about 600,000,000 yuan.
Negative-pressure sealed drainage technology is realized by negative-pressure sealed drainage system, it include porous foam cushion, one
Drainage tube that end is arranged in porous foam cushion, for the sealing film of sealing porous airfoam cushion.By assembling drainage tube
Porous foam cushion is laid on wound surface, seals with sealing film, and drainage tube is connected negative pressure, thus establish at wound surface
One drain district closed, carries out negative-pressure sealed drainage constantly.With existing commonly change dressings compared with, negative-pressure sealed drainage technology
Can will be removed in good time by porous foam cushion and drainage tube by the exudate in drain district and slough, so that
Be can reach " nil product is gathered " state by drain district, wound surface is under lasting cleaning ambient, greatly reduces body contratoxin
Heavily absorption；Even if with the presence of bigger lacuna, lacuna also accelerates to reduce because of the existence of negative pressure.For shallow table wound surface, close
Sealing film and porous foam cushion also make local environment closer to physiological moisture state；Meanwhile, wound surface soft tissue is acted on
On negative pressure stimulate, the beneficially improvement of local microenvironment and disappearing of tissue edema, accelerate the new of granulation tissue in wound surface
Raw, shorten wound healing time.Under negative-pressure sealed drainage technology is treated, wound surface without changing dressings, reduced medical matters people in 3-7 days
The workload of member, decreases patient suffering, reduces 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.
But, finding in use in recent years is treated, find time in practical operation, negative pressure drainage device is due to design not
Rationally, pressure leakages often occur, medical personnel need the operation of long period, could realize the closed negative pressure shape of device
State, the irrationality of operation increases the working time of medical personnel, adds the relative risk of successful surgery, is unfavorable for operation
Efficiently carry out.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned background technology, it is provided that a kind of efficient operation negative-pressure sealed
Drainage system, is applied to protect in invasive procedures and trauma operation can being treated, drain district carries out effective negative-pressure sealed drainage, and system can depend on
The sepage of drain district is treated so that it is be in zero gathering environment, it is to avoid form abdominal cavity diffusivity and infect, subtract by negative pressure active, efficient drain
Few body toxin absorption, reduces the post-operative complication probability caused because of infection, hemorrhage, leakage of body fluids etc., accelerates wound healing.
The technical solution of the utility model: the negative pressure closed drainage device of a kind of efficient operation of the present utility model includes many
Hole foam, the drainage tube being placed in porous foam, medical pad pasting, sucker, the drainage catheter on sucker is connected with negative pressure system,
Its porous foam is block foam material, one end of the exit connecting bending joint of the drainage tube being placed in porous foam, curved connects
The other end of head is stretched out by the top of block foam material；Medical pad pasting includes covering sealing pad pasting and ring packing pad pasting, covers
Lid seals pad pasting and is used for covering block foamed materials, and covering to seal has circular hole on pad pasting, the position of circular hole and number and bent sub
Correspondence, the diameter of circular hole mates with bent sub；The inner ring of ring packing pad pasting amplexiforms on sucker, the outer ring of ring packing pad pasting
Bottom has release paper to protect.
The size of described block foam material is 15 × 10 × 1cm, and its interior aperture is 50～60ppi.
Described drainage tube sets two, and the length direction along block foam material is arranged, two bent subs stretch out block bubble
The height on foam material top is 2～3mm.
The radial width of the outer ring release paper of described ring packing pad pasting is 5～10mm.
This utility model has the advantage that 1. this utility model facilitates medical personnel to operate, and increases the one-tenth of once-through operation
Merit, reduces traumatic infection, extent of hemorrhage, accelerates wound healing, trauma operation can being treated, drain district carries out effective negative pressure envelope
Closing drain, system can rely on negative pressure active, efficient drain to treat the sepage of drain district, reduces body toxin absorption, reduces because infecting, going out
The post-operative complication probability that blood, leakage of body fluids etc. cause；2. the integrated design of device and the use of sucker effectively raise
The easy degree of operation, will effectively reduce operating time and the patient suffering of medical personnel；3. the comfortableness of system can carry
For the Curing circumstance that patient is good, improve therapeutic effect.
