The utility model discloses a theory of operation and use:

when in use, the skin around the wound of a patient needs to be wiped and disinfected, if the skin is debrided by carrion, the alginate dressing 10 is cut according to the shape and the size of the wound to be equal to the size of the wound, the connecting pipe 13 is in threaded connection with the supporting component 12, the connecting pipe 13 stops rotating after the limit 123 at the lower end of the connecting pipe 13 is abutted against the inside of the threaded hole 122, the film 11 is sleeved on the connecting pipe 13, the head end of the first suction pipe 3 is in threaded connection with the connecting pipe 13, the head end face of the first suction pipe 3 is pressed on the sealing washer 111 during connection, the lower surface of the sealing washer 111 is abutted against the upper surface of the abutting ring 124, the first suction pipe 3 and the second suction pipe 4 are connected with the liquid storage bottle 2, the regulating valve 40 is closed, the inserting head 5 is in negative pressure connection with the wall, the alginate dressing 10 is covered on the wound of the patient, the adhesive patches 112 at the peripheral edge of the film 11 are torn, make the sticker 112 laminate on patient's wound periphery skin, film 11 makes the wound department become a confined cavity, rotate governing valve 40, how much open governing valve 40 angle according to patient's sepage volume, make it keep in 20KPA ~ 40 KPA's negative pressure interval, when patient wound department appears the sepage, the sepage is absorbed by alginate dressing 10, can flow to in supporting component 12 runner 120 through drawing hole 121 when alginate dressing 10 absorbs a certain amount of sepage, and then in being drawn to the stock solution bottle 2 by first suction tube 3, after the liquid that the stock solution bottle 2 is inside absorbs is full of, close governing valve 40, separate first suction tube 3 and second suction tube 4 with stock solution bottle 2, pour out the interior liquid of stock solution bottle 2 that flows backwards, because the existence of check valve 30 when first suction tube 3 and stock solution bottle 2 separate, so bacterium etc. can't enter wound department. The alginate dressing 10 is a natural polysaccharide carbohydrate extracted from seaweed, which is a natural cellulose. The alginate dressing 10 is a functional wound dressing with high absorbent properties. After the alginate dressing 10 is contacted with wound exudate, a soft gel can be formed, an ideal moist environment is provided for wound healing, wound healing is promoted, wound pain is relieved, and good antibacterial activity is achieved. First suction tube 3 and second attract 4 pipe walls inside all to be equipped with aluminium strip 6 its effect is convenient for stereotype first suction tube 3 and second and attract pipe 4, prevents it curling and perk, buckles when avoiding first suction tube 3 and second to attract pipe 4 to connect and causes the lumen to block up closed. The effect of the first suction tube 3 abutting against the sealing gasket 111 is to keep the wound of the patient in a closed space.
