The specific embodiment

A kind of portability pulsed negative pressure wound surface drainage instrument pasting with Wound-surface negative pressure, comprise underbalance pulse generator 1, on underbalance pulse generator 1, there are display screen 3, switch 2, it is characterized in that, continuous gap by-pass cock 4 by microcomputerized control is also housed on underbalance pulse generator 1, the close shell base section of underbalance pulse generator 1 is for solidifying chamber 5, solidifies that chamber 5 is in-built a nontoxic coagulant (for wound waste liquid is solidified); Solidify 5 sides, chamber have upper and lower two skirt mouths, one 6(upper draft tube mouth 1 can be used for ventilation), the close shell facial parts of underbalance pulse generator 1 is diversion chamber (for the drain of wound waste liquid is come in), diversion chamber side has upper and lower two skirt mouths 27; Lower draft tube mouth 1 and lower draft tube mouth 27 use pipes are communicated with (for the circulation of wound waste liquid); Upper draft tube mouth 27 use pipes are communicated with the wound surface mouth of pipe 8, the wound surface mouth of pipe 8 belows are connected with silica gel support cover 9, medical sponge 12 is equipped with in silica gel support cover 9 the insides, medical sponge 12 is connected with medical oily layer 10 below, the silica gel support cover 9 of medical oily layer 10 surroundings has double faced adhesive tape 11 below, post double faced adhesive tape 11, make wound sealing, easily make the waste liquor stream pass-out of wound surface go; Regulate continuous gap by-pass cock 4, can make underbalance pulse generator 1 continuous or interval work as required.The invention makes granulation fast growth.

Performance analysis

Company is making a product professional, scientific, Wound treating means combination advanced, higher curative effect for patient, and makes every effort to find the binding site of economic benefit, health-benefiting and a social benefit.

1. economic benefit

Investigation shows, acute and chronic Wound treating accounts for 8%--10% in clinical patients, in inpatients in surgical department, account for 2%--4%, estimate about 100-150 ten thousand people of patient that are in hospital because for the treatment of every year, add the wound that various large operations cause, estimating needs the patient for the treatment of greatly about 1000-2000 ten thousand people every year.And there is large ascendant trend.According to the basic demand of clinical treatment, a patient's Wound treating on average needs 2 cover materials, and the demand of whole market is at 2000-4000 ten thousand covers so.

The production capacity that my company produces 100000 covers per year only account for 1% left and right in market, can enforcement sale 6,000 ten thousand yuan by the present market price.

2. environmental benefit

Wound treating material sleeve is contained in the use of medical institutions, in clinical treatment, Wound treating will be greatly reduced to the quantity of changing dressings, thereby reduces hospital refuse.The wound surface infecting on the other hand by the closed drainage of wound surface after by the aerial infection greatly reducing in institute, improve the air quality in ward.

3. social benefit

Wound treating material sleeve is contained in the use of medical institutions, will the clinical treatment means of revolution type occur in acute and chronic Wound treating.With regard to that diabetes foot disease, by treatment, greatly reduce the possibility of amputation.Patient can, from anti-work position, set up life normally by treatment.

Four. the value of product clinical practice

Pulsed negative pressure granulation fast growth, it is better than continuous negative pressure and gap negative pressure.

2. little wound surface, out-patient treatment, does not take nervous berth.

3. large, medium and small hospital, community medical service center can be used.

Good curative effect, alleviate medical worker's workload simultaneously.

5. reasonable disposition medical resource.
