Description
Technical field
This utility model relates to a kind of device for Wound treating, is specially a kind of negative pressure micro-oxygen device for Wound treating.
Background technology
When existing negative pressure drainage equipment uses, first, outside wound face, cover dressing; Secondly, the space formed between dressing and wound face is set to negative pressure; Then, under the effect of the flexible pipe in this space of UNICOM, wound fluid is carried out drain, thus ensureing the cleaning of wound surface. In this process, the partial pressure of oxygen in space is lower than the partial pressure of oxygen in environment. It is known that oxygen is extremely important for wound healing: oxygen can promote the respiratory burst of inflammatory cell, thus producing the function of phagocytosis antibacterial, promoting the growth of blood capillary, promoting the growth of collagen protein and skin. Therefore, while wound surface being carried out negative pressure drainage, extracts transudate, it is often desired to wound surface oxygen supply, in order to wound surface recovers rapidly.
When Wound treating, the oxygen flow that wound surface needs can calculate by the following method, it may be assumed that
(1) containing the oxygen of about 21% in the air that human body sucks, containing the oxygen of about 16% in the air of exhalation, therefore breathing can consume and suck the oxygen of 5% in air every time. The respiratory capacity of Human Lung is approximately 8 liters/min, therefore, breathes one hour, and the amount of human consumption pure oxygen is: 8 liters/min �� 60 minute/hour �� 1000 ml l �� 5%=24000 ml/hour.
(2) surface area of lung about 100 square metres, namely 1000000 square centimeters. Therefore, per hour, the oxygen flow that every square centimeter of lung surface consumes is: 24000 mls/hour of �� 1000000 square centimeters=0.024 milliliter/(hour �� square centimeter).
(3) assume that the oxygen that pulmonary a certain area sucks all is absorbed by wound of the same area, then for wound that area is S square centimeter, it is possible to obtain oxygen flow theoretical maximum F be:
F=0.024 �� S(ml/hour)
Definition F is the suitable oxygen dosage of wound. Such as: for the wounds of 64 square centimeters (centre of the palm size), suitable oxygen dose F=0.024 milliliter/(hour �� square centimeter) �� 64 square centimeter=1.536 ml/hour.
At present within the hospital, the terminal oxygen-supplying amount that patient uses is 1 liter/min to 5 liters/min, be above-mentioned 64 square centimeter wound suitable oxygen dosage 3.9 �� 104��1.95 �� 105Times, it can be seen that, the oxygen therapy dosage that when flow of the existing oxygen of hospital is considerably beyond Wound healing and bone regeneration, cell is actually needed.
But, if the keeping terminal of hospital and negative pressure drainage equipment are used in combination, problems with can be caused: (1) is huge due to oxygen-supplying amount, the wound surface being easy under being covered by dressing dries up, so that wound surface connects crust, hinders the growth of creeping of skin, delay healing speed, therefore, actual therapeutic effect of oxygen is not only brought into play, has the opposite effect on the contrary. (2) owing to oxygen-supplying amount is huge, cause that the space between dressing and wound surface is difficult to reach negative pressure, wound surface is in ambient pressure state (such as 1 atmospheric pressure) or all the time slightly above ambient pressure state, in this case, not only wound fluid can not be carried out drain, and the vacuum sensor of negative pressure equipment can not measure the negative pressure value set all the time, makes the vacuum pump of negative pressure equipment be in full load continuous duty, thus greatly reducing the service life of vacuum pump.
