Description
Technical field
It is especially a kind of convenient for generation negative pressure manually the present invention relates to the portable negative pressure device used in a kind of negative pressure dressing
The portable negative pressure device in source.
Background technology
The normal healing of body wound be one by damaging when i.e. act on complex process.First, body is by making
Blood flows to wound, to deliver protein and other blood coagulation substances, minimizes injury.Blood clotting is then preventing from losing
Blood, while the bacterium of cell phagocytosis wound and remains.Next, being referred to as the healing phases of proliferation period, body starts to repair
Itself, granulation tissue deposition is in wound surface.Granulation tissue provides foundation structure on wound, cell can from the periphery of wound to
Internal migration is to surround closing wound.Finally, as the time elapses to form scar.
In the prior art, wound dressing suctions out blood and tissue that all wounds ooze out only with the mode of physical absorption
Liquid makes wound keep drying.However, wound dressing of the prior art and the ambient humidity of wound perimeter is unable to control, excessively
Dry environment can influence the healing of wound instead.
One kind is referred to as negative pressure wound therapy (negative pressure wound treatment, NPWT), and being can be
During proliferation period, the technology that wound moisture is controlled to promote normal healing process is utilized.Negative pressure wound therapy is to utilize negative pressure source, example
Such as vacuum pump, with reference to sealing patch, soft sucker and bio-compatibility porous material, subnormal ambient is formed in wound to take out
Sepage is taken, such as wound fester and infected material, health tissues liquid is attracted to maintain moist Curing circumstance, and blood is micro- arround promotion
It cycles and achievees the effect that accelerating wound healing.Negative pressure wound therapy utilizes the normal healing process of body, can effectively facilitate
Blood flow to wound area, and stimulates the formation of granulation tissue and the migration of health tissues above wound.Negative pressure wound therapy,
By removing the tissue fluid isotonic solution with nutrient and easy growth bacterium oozed out from wound, to inhibit bacteria growth.
In the prior art, the system for negative pressure wound therapy can substantially divide into sepage collection vial-type and be applied with absorbing pattern
Expect two kinds of systems.Though which kind of system its be both needed to using additional negative pressure source, it is however generally that be often Motorized vacuum pumping.Due to electricity
Dynamic vacuum pump possesses motor structure, so being less favorable for carrying in volume, and needs to be additionally provided power supply.Especially when use is oozed
When liquid collects the negative pressure wound treating system of vial-type, also need to use additional sepage receiving flask, thus for still taking action but
The sufferer that need not be liied in bed for a long time, in the prior art, the negative pressure wound treating system that vial-type is collected in additional sepage limit disease
The daily action suffered from, more causes inconvenience in life.And for using absorb pattern dressing negative pressure wound treating system, then because
It is limited for the sepage uptake of dressing, and relatively frequent more change dressings is needed, also easily cause sufferer discomfort.
Therefore, a kind of portable negative pressure device suitable for negative pressure wound treating system is needed exist for, it is additional to improve
The inconvenience caused by the negative pressure wound treating system of vial-type is collected in sepage, and can be provided compared to the absorption more sepages of pattern dressing
Collection capacity.
