Description
Technical field
The present invention relates to medical instruments field, specifically a kind of for safely and fast sealed negative-pressure sealed drainage system
Diaphragm seal.
Background technology
Negative-pressure sealed drainage technology (vacuum sealing drainage, abbreviation VSD) is German ULM universities Wim
Doctor Fleischman is pioneering in 1992, and forms theoretical blank, for the drainage of limb wounds；China Qiu Huade in 1994
Negative-pressure sealed drainage technology is applied to department of general surgery by professor first, has started the elder generation that negative-pressure sealed drainage technology is applied in department of general surgery
River, Wang Yanfeng, Qiu Huade are taught in China in authorized patent CN2276350 of on March 18th, 1998, are negative-pressure sealed drawing
First patent of Flow Technique.From this, negative-pressure sealed drainage technology has obtained larger development in China.
Negative-pressure sealed drainage technology realized by negative-pressure sealed drainage system, it include porous foam cushion, one
End is arranged on drainage tube in porous foam cushion, for the sealing film of sealing porous airfoam cushion.By assembling drainage tube
Porous foam cushion is laid on the surface of a wound, is sealed with sealing film, and drainage tube is connected negative pressure, so as to establish at the surface of a wound
The drainage area of one closing, carries out constantly negative-pressure sealed drainage.Compared with existing common dressing, negative-pressure sealed drainage technology
Porous foam cushion can will be passed through by the exudate and slough in drainage area and drainage tube is removed in good time, so that
" nil product is gathered " state can reach by drainage area, the surface of a wound is under lasting cleaning ambient, greatly reduces body contratoxin
Reabsorption；Even if with the presence of larger lacuna, lacuna also accelerates to reduce because of the presence of negative pressure.It is for the superficial surface of a wound, close
Sealing film and porous foam cushion also make local environment closer to physiological moisture state；Meanwhile, act on surface of a wound soft tissue
On negative pressure stimulate, be conducive to the improvement of local microenvironment and the regression of tissue edema, accelerate the new of granulation tissue in the surface of a wound
It is raw, shorten wound healing time.Under the treatment of negative-pressure sealed drainage technology, without the need for dressing in surface of a wound 3-7 days, medical matters people is reduced
The workload of member, reduces patient suffering, reduces general practice expense.
In China, negative-pressure sealed drainage technology is widely used in：The fields such as Department of traumatology, orthopaedics, department of general surgery, Department of B urn.
In negative-pressure sealed drainage system, closing is premise, and good surface of a wound sealing could provide enough negative pressure to wound
Treated in face.However, mostly being rectangle currently used for the diaphragm seal of negative-pressure sealed drainage system sealing, rectangular membrane is sealed for negative pressure
The sealing for closing drainage system is extremely complex and loaded down with trivial details.Due to being equipped with one in porous foam cushion in negative-pressure sealed drainage system
Or many drainage tubes for being furnished with ring set glued membrane, need to ensure the sealing of whole negative-pressure sealed drainage system, it is necessary to many in good seal
Again drainage tube surrounding is sealed after the airfoam cushion of hole, rectangular membrane need to be cut into multiple membranelles by this process, individually to drawing
Flow tube ring set glued membrane surrounding is sealed, and this process operation time is long, and easily produces poorly sealed situation, whole so as to cause
Individual negative pressure system gas leakage.Although one or more holes will can be opened in rectangular seal film by hand in clinical manipulation, then by one
Root or many drainage tubes pass through the hole, carry out sealing and can ensure that sealing, but in practical operation, and drainage tube is longer and material
It is harder, drainage tube is difficult into operation through the action of hole on film, diaphragm seal is also easy to adhere to by mistake and causes pad pasting on drainage tube
Failure.Meanwhile, the method is only applicable to the operation that individual negative-pressure sealed drainage protects traumatic material, and multiple negative-pressure sealed drainage materials are simultaneously
Used time, the interference between drainage tube can make very wasting time and energy for the operation change of the method, and sealing also effectively cannot be protected
Card.
Once sealing cannot be guaranteed in negative-pressure sealed drainage system, due to gas leakage, first, negative pressure will be unable to obtain
Ensure, wound fluid can be made to be deposited in the surface of a wound and cause toxin double absorption, cause surface of a wound severe infections, increase patient suffering and
Medical expense.Secondly, it is impossible to which closed space can cause moisture to be lost rapidly, it is impossible to which simulation is closer to physiological moistening shape
State, can have a strong impact on the healing rate of the surface of a wound.Finally, gas leakage can cause the rapid of some local of negative-pressure sealed drainage shield traumatic material
It is dry and hard, cause blocking in negative-pressure sealed material, have a strong impact on drainage effect.
Therefore, because existing sealing membrane operations complexity excessively can increased operating time.Poorly sealed gas leakage simultaneously can cause
The therapeutic effect of negative-pressure sealed drainage system weakens even failure
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned background technology, there is provided a kind of to seal for safely and fast sealed negative-pressure
The diaphragm seal of drainage system is closed, its simple structure is easy to use, operability and sealing property are excellent, can be rapidly to negative-pressure sealed
Drainage system carries out seal operation, while being applied to plurality of materials and being used in series.
