Description
Technical field
The invention belongs to negative pressure wound therapy monitoring technical field, be specifically related to a kind of negative pressure wound treating system.
Background technology
Generally speaking, wound healing or wound healing (Wound healing) is the natural process of human body skin and epidermal tissue regeneration after wound.Normal, the epidermis (outermost layer) of skin and corium (inside or deep layer) are present in the state of a balance, to form the barrier of a protection wound.And break when eschar, normal wound healing process just can promptly start.Its basic process comprised with the next stage: post-hemorrhagic period, inflammatory phase, proliferative phase, maturation and reinvent the phase.
Post-hemorrhagic period relate to wound response and repair in the first step, comprise hemorrhage, solidify and platelet and complement activation.Inflammatory phase peaks in the time that first day closes to an end, and shows as hyperemia, serosity oozes out and leukocyte guerrilla warfare, therefore local red and swollen.Leukocyte, take neutrophilic granulocyte as main, transfers to take macrophage as main after 3 days.Fibrinogen in blood and transudate in wound solidifies formation grumeleuse very soon, and some grumeleuse dry tack frees form crust, and grumeleuse and crust play a part protection wound.
The hyperplasia phase appears at ensuing one in thoughtful one month, occurs that fibroplasia, revascularization, re-epithelialization and extracellular matrix are synthetic.Wound contraction after 2～3 days whole layer skin and the subcutaneous tissue of edge of wound move to center, so wound dwindle rapidly, until stop about 14 days.In wound, initial collagen forms generally and peaked after about 7 days.Under optimum condition, wound re-epithelialization appeared at about 49 as a child, and now wound may be completely sealed.Wound in healing can have 15% to 20% full tensile strength in the time of 3 week, and in the time of 4 months, has 60% full strength.After first month, degrade and reinvent the stage, wherein cellularity and vascularity reduce, and anti-tensile degree increases.Approximately grow granulation tissue since the 3rd day from wound bottom and edge, fill and lead up wound.Blood capillary is approximately to extend the speed increment of 0.1～0.6mm every day, and its direction is mostly perpendicular to wound surface, and is loop sigmoid.In granulation tissue, there is no nerve, therefore numbness.Within 5th～6 days, play fibroblast and produce collagen fiber, collagen fiber formation in one week is thereafter very active, slows down gradually later.Along with collagen fiber are more and more, there is Process of Forming Scar.The formation of mature scar usually needs 6-12 month.
Negative pressure wound therapy (Negative Pressure Wound Therapy, NPWT) is the advanced trauma care mode that development in recent years is got up.Be different from traditional wound care and negative pressure drainage technology, negative pressure wound therapy mainly adopts lower negative pressure (arrive-175mmHg of general-55mmHg), step working method treatment wound.The negative pressure wound therapy adopting in recent years shows the blood flow that has improved wound or tissue site clinically, has increased tissue growth, can reduce infection simultaneously, is conducive to the healing of wound.Can treat various acute and chronic wounds with negative pressure wound treating system clinically, such as diabetic wounds, trauma wounds, cosmetic surgery wound, burn wound etc.
Negative pressure wound therapy energy wound healing be the result of mechanism and multiple effect: vacuum suction acts on cell membrane, make it expansion, distortion, cell is just thought damage, the information of conduction impairment is to nucleus, change by signal, cause the front healing of emiocytosis somatomedin, comprise the vascular proliferation factor, thereby stimulate tissue to produce more new vessels.Vacuum suction siphons away and oozes out from wound surface, helps to set up wound surface fluid balance; A moistening environment is provided; Remove slough; Reduce the bacterial number (because antibacterial is difficult for survival under negative pressure) of wound surface; Alleviate edema (being extracellular fluid/intercellular fluid); Increase wound surface blood flow, by increasing capillary filling; Increase somatomedin.(owing to having increased the blood flow that flows to wound surface); Promote that leukocyte and fibroblast enter wound surface, wherein leukocyte can be resisted infection, and generation somatomedin, and fibroblast can produce collagen is used for filling and leading up and repairing wound; Increase venous engorgement, and then accelerate to remove edematous fluid (" refuse " is along with edematous fluid is excluded wound surface thus); Increase the lymphatic drainage from wound surface, mechanism is by changing vasculolymphatic pressure and colloid osmotic pressure, and these changes are another reasons of accelerating edema and refuse eliminating.Make to organize close, thereby the strength that tissue is had an opportunity by physics naturally sticks together, this is very useful for accelerating healing.Except sucking action also can produce contention effect.The reason producing is to act on dressing when captivation, and air is sucked away, and dressing is with regard to collapses down (being easy to see), and compressing acts on wound surface uniformly, and this pressure resists the excessive of wound surface causing and oozes out.This mechanism is particularly important for Patients with Big Area Burn, can make patient lose too much plasma protein because a large amount of wound surface oozes out, and increases the possibility that hypovolemic shock occurs.
Wound negative pressure therapeutic instrument (Negative Pressure Wound Therapy Devices, referred to as NPWT), its principle, for by apply negative pressure to wound, promotes the healing of wound.Clinical showing according to the U.S. over nearly 10 years, this equipment has good healing effect to the treatment of wounds of various acute and chronics.Referring to Fig. 1, be a kind of common wound negative pressure therapeutic instrument (NPWT), comprise Wound treatment apparatus 9 and wound external member 8.Wound external member 8 is for wound closure, and Wound treatment apparatus 9 is for createing needed wound negative pressure.Specifically, negative pressure wound therapy instrument comprises the parts such as control module 7, negative pressure source 6, liquid-collecting bottle 5, pipeline 4, and wherein, the pressure of negative pressure source 6 is controlled by control module 7, and the pipeline 4 being connected between negative pressure source 6 and wound 1 is provided with liquid-collecting bottle 5.When treatment, at wound, wound dressing 2 is filled at 1 place, and pipeline 4 is inserted in wound dressing, seals above with pad pasting 3, by applying negative pressure to wound, promotes wound circumference blood circulation, accelerates the healing of wound.
And in actual therapeutic process, no matter be in medical institutions or in patient family, capital is subjective or have objectively a situation of carrying out therapy not according to doctor ordered, or the therapy that also may arrange at first exists the possibility of error or the defect due to some external force or therapeutic equipment itself, cause completing the therapeutic outcome of doctor's expection.In this case, wound often can not correctly heal, and clinician's NPWT equipment that cannot use by patient understands the problem existing in therapeutic process, may bring infliction of body to patient, or delay treatment duration, cause the loss on time and money.The present invention therefore.
