Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality It is further elaborated with novel.

As shown in Figure 1, 2, simple wound Persistent Vacuum system disclosed by the utility model, including foam block 1, Unidirectional extraction valve 2 and for the adhesive film 4 be bonded with skin, unidirectional extraction valve 2 has the suction interface 3 of evagination.As shown in figure 3, Adhesive film 4 is equipped with the through-hole 5 being pierced by for suction interface 3, and unidirectional extraction valve 2 is set to the front of foam block 1, unidirectional extraction valve 2 Entrance towards foam block 1, adhesive film 4 covers foam block 1 from 1 front of foam block, and suction interface 3 passes through through-hole 5 and exposes to Adhesive film 4, the adhesive surface of adhesive film 4 is towards the back side of foam block 1.

For convenience of observation, adhesive film 4 is transparent material.Wherein, unidirectional extraction valve 2 is furnished with the lid being adapted to suction interface 3 Cap 6.

Simple wound Persistent Vacuum system further includes the pump bowl 7 being adapted to suction interface 3.As shown in figure 4, Pump bowl 7 is hand-operated pumping cylinder.

As shown in Figure 1,5, simple wound Persistent Vacuum system further includes hospital gauze 8, the face of hospital gauze 8 Product is greater than the area at 1 back side of foam block.The area of adhesive film 4, can cover with it is closed live foam block 1, preferably, viscous The area of pad pasting 4 is greater than the surface area of foam block 1.

The utility model structure is simple, and materials are convenient, following is a brief introduction of the application method of the utility model:

Prepare material: hospital gauze, medical foam (being used as foam block 1), medical transparent rubberized fabric (being used as adhesive film 4), city The unidirectional extraction valve (the optional dedicated plastics extraction valve of vacuum compression bag is furnished with nut cap) and hand-operated pumping cylinder sold.Medical bubble Foam is soft, and porous, strong adsorption force, retractility is good, is conducive to vacuum suction.

Operating procedure is as follows:

Hospital gauze 8 is covered on wound；

Medical foam is placed on hospital gauze 8；

Then unidirectional extraction valve 2 is placed on medical foam, the entrance of unidirectional extraction valve 2 is towards foam block 1, and with medical For transparent rubberized fabric by medical foam and the covering closing of unidirectional extraction valve 2, the periphery bonding of medical transparent rubberized fabric is on the skin, medical Gelatin cloth is also Nian Jie with unidirectional 2 outer surface of extraction valve to prevent gas leakage simultaneously；With hand or other tools on medical transparent rubberized fabric Tearing an osculum makes the suction interface 3 of unidirectional extraction valve 2 be pierced by medical transparent rubberized fabric in order to be evacuated；

Hand-operated pumping cylinder is connect with suction interface 3, is then evacuated, it is medical since medical transparent rubberized fabric surrounding is closed Generate negative pressure in gelatin cloth, medical foam is compressed, and then draws out the extravasated blood in wound etc.；

Hand-operated pumping cylinder is connect with suction interface 3, is then evacuated, it is medical since medical transparent rubberized fabric surrounding is closed Negative pressure is generated in gelatin cloth, medical foam is compressed；

It takes hand-operated pumping cylinder away, as shown in figure 5, the closing valve on unidirectional extraction valve 2 is covered in nut cap 6, prevents pumping from connecing Mouth is contaminated.

Compressed medical foam can slowly draw out the extravasated blood etc. in wound, and extravasated blood of suction etc. is by hospital gauze and doctor With foam absorbing, will not flow down.

The utility model directly disposes unidirectional extraction valve on medical foam, by being evacuated bucket manually, forms system negative pressure State does not need external pumping and attracts equipment, allows for patient in this way while treatment, can move freely or work, than Compared with the family therapy of the suitable refractory wound of chronic long, while reducing the complication such as patient's long-term immobilization bring thrombosis.

Certainly, the utility model can also have other numerous embodiments, without departing substantially from the spirit of the present invention and its essence In the case where, those skilled in the art can make various corresponding changes and modifications, but these according to the utility model Corresponding changes and modifications all should belong to the protection scope of the utility model the attached claims.
