The utility model discloses a kind of anti-infiltration devices for abdominal cavity drainage tube, it is related to medical auxiliary appliance technical field, when using conventional drainage tube, because the suture gap exists between the smaller drainage tube diameter and abdominal wall puncture hole, postoperative ascites is easily leaked outside through the gap inserted by drainage tube, increase the risk of infection and off pipe, and wound exudate is alkaline, continuous skin irritation aggravates patient's pain, delay healing time, increase patient's medical cost.The utility model provides a kind of anti-infiltration device for abdominal cavity drainage tube, including drainage tube, annular groove is arranged on the drainage tube, negative pressure disc is arranged on the annular groove, the negative pressure disc is slidably connected with drainage tube, expansion air bag capable of extruding negative pressure disc is also arranged on the annular groove, fixed air bag is also arranged on the drainage tube, the fixed air bag is arranged at one side of annular groove, and expansion air bag is respectively arranged at both sides of negative pressure disc, can avoid drainage tube off pipe, avoid exudate leakage.

This invention belongs to the field of external application of traditional Chinese medicine preparations, specifically relating to a waterproof dressing for wound protection. It comprises plant charcoal, plant oil, and a traditional Chinese medicine ointment, wherein the plant charcoal, plant oil, and traditional Chinese medicine ointment are mixed and prepared into a paste in a weight ratio of (0.3-2.5):3:(0.5-2.7). The technical solution provided by this invention uses simple plant charcoal, plant oil, and traditional Chinese medicine ointment to form a stable protective layer on the wound surface using the wound's own exudate. Once fully cured, it does not peel off upon contact with water, greatly reducing the risk of infection. Furthermore, it allows for the easy addition of other traditional Chinese medicine ingredients to achieve other therapeutic purposes such as promoting healing and inhibiting bacteria.

The utility model discloses a kind of water-absorbing dressings, it is related to dressing technical field, including backing layer, the side fixedly connected with absorption core layer of backing layer, the outside fixedly connected with contact layer of absorption core layer, the outer layer of contact layer to inner layer is sequentially composed of response layer and biological activity layer, the outer layer of absorption core layer to inner layer is sequentially composed of flow guide layer, absorption layer and prevent reverse osmosis layer, the outside of contact layer is adhered with release paper, the side of absorption core layer of backing layer is adhered with pasting layer, the outside fixedly connected with positioning block of backing layer, the outside fixedly connected with belt of positioning block, the end fixedly connected with connecting block of belt, and connecting block and the positioning mechanism between backing layer are installed. The device is automatically adjusted hydrophilic and hydrophobic through temperature-sensitive hydrogel, combined with silk fibroin to continuously promote healing, flow, absorption and reverse osmosis prevention structure synergistic management exudate, supplemented with flexible traction design to reduce peeling damage, interlayer closely adheres to avoid side leakage, improve nursing efficiency and comfort.

The utility model discloses a kind of wound exudate precision measurement and drainage device, including the drainage bottle with scale outside, the upper portion of drainage bottle is sequentially communicated with drainage hose, temporary storage capsule and the connecting pipe with liquid collecting capsule, further include the liquid injection pipe of communication setting in temporary storage capsule top, same support plate is fixed on connecting pipe and liquid injection pipe, the central position of support plate is rotatably connected with carousel by pivot, switch opening is set on carousel, it has beneficial effect for: through the temporary storage capsule of setting, can store exudate when drainage hose is blocked, ensure that wound exudate is discharged in time, prevent local hydrops, simultaneously, by the cooperation of liquid injection pipe and carousel, flushing fluid or gas can be injected into temporary storage capsule, to flush or pressurize the inside of drainage hose, so that the blockage in the inside of drainage hose enters drainage bottle, thereby improve the drainage efficiency of exudate.
