Be located to be equipped with state display portion between portion 3 of giving medicine to the poor free of charge and the barrier layer 2, state display portion includes permeate liquid receiving part and pH test paper 41, and pH test paper 41 sets up on permeate liquid receiving part, and permeate liquid receiving part is used for leading the outer permeate liquid water conservancy diversion on the barrier layer 2 to pH test paper 41. When the device is used, the medicine applying part 3 and the blocking layer 2 are laid on a wound, the area of the medicine applying part 3 is usually far larger than that of the wound part, and a large amount of external seepage liquid flows out at the initial stage of the wound, and the external seepage liquid can directly reflect the state of the wound part, so that the pH value of the wound part can be directly tested by collecting the external seepage liquid. The pH value of a wound surface is an important influence factor in a healing process, the bacteriostatic effect under different pH values has different clinical effects, the bacteriostatic effect is best under an acidic environment (pH is 5), the bacteriostatic effect of the wound surface is weakened along with the increase of the pH value, the bacteria grow optimally when the pH value is 7, the bacteria grow under an alkaline environment, but the bacteria grow under an alkaline environment, compared with the acidic environment (pH is 5), the bacteria grow under a weak inhibition capability, and the pH value is in a decreasing trend along with the improvement of the wound surface; and the pH value of the unhealed wound is obviously higher than that of the healed wound, so that the pH value can be used as an index for predicting whether the wound is normally and well healed.

The sepage receiving part includes the album of liquid layer and observes membrane 42, and the end of drawing liquid on album liquid layer is thought to the contact with barrier layer 2, and the hydrops end on album liquid layer contacts with pH test paper 41, observes the one side that the barrier layer 2 was kept away from in album liquid layer was located in the adhesion of membrane 42. The observation membrane 42 is a transparent film and is adhered to the liquid collection layer and the upper side of the pH test paper 41, so that the liquid collection layer is sealed to prevent the pH test paper 41 from being influenced by external environment or substances, so that the detection result is interfered, and the medical staff can observe the color reaction of the pH test paper 41 visually. Meanwhile, in order to take out the pH test paper 41, a detection window 421 is arranged at a position of the observation film 42 corresponding to the pH test paper 41, a sealing film is adhered on the detection window 421, when the wound has less extravasation liquid, only one side of the pH test paper 41 close to the liquid leading end can be contacted with the extravasation liquid to generate a color reaction, and the reflection is not obvious at one side far away from the liquid leading end, so that the specific color is inconvenient to see during observation and cannot be judged.

As shown in fig. 2, the liquid collecting layer includes a plurality of liquid guiding units, each liquid guiding unit includes a plurality of liquid guiding tentacles 43 and a liquid collecting tip 44, one ends of the plurality of liquid guiding tentacles 43 are distributed and fixed at different positions of the liquid collecting layer, and the other ends of the plurality of liquid guiding tentacles 43 are fixed on the liquid collecting tip 44 in a gathering manner. The multiple groups of liquid guiding tentacles 43 are arranged at positions close to the wound on the blocking layer 2, so that extravasated liquid can be conveniently printed on and collected to the liquid accumulating end 44 by the liquid guiding tentacles 43 in time, meanwhile, in order to ensure that the extravasated liquid can be smoothly conducted along with the liquid guiding unit and cannot leak, anti-seepage films are fixedly arranged on the upper surface and the lower surface of the liquid guiding unit, the upper surface of the liquid accumulating end 44 is not covered by the anti-seepage films so as to ensure that the liquid accumulating end 44 can be directly contacted with the pH test paper 41, and the part of the lower surface of the liquid guiding unit, which is close to the finger end of the liquid guiding tentacles 43, is not covered by the anti-seepage films so as to facilitate the liquid guiding tentacles 43 to be directly contacted with the extravasated liquid. The drainage unit is made of a material with strong suction and seepage capabilities, such as rice paper or cotton material, so as to guide the extravasated liquid to the effusion head 44.

As shown in fig. 3, the liquid collecting layer can also be provided with a plurality of groups of guide ropes 45. The middle portion of the guide string 45 is coated with the impermeable film, and both end portions of the guide string 45 are not coated with the impermeable film. One side of the two end parts without the coating is contacted with the pH test paper 41, and the other side is contacted with the overflow area of the outer seepage liquid in the barrier layer 2. The dressing in this state is used in the middle stage of wound recovery, and since the amount of the extravasation liquid of the wound has been reduced at this time, the extravasation liquid cannot be contacted in a place away from the wound, it is necessary to dispose the liquid collecting layer at a position closer to the wound or even just above the wound, and in order not to shield the contact area of the administration portion 3 and the wound, it is necessary to use a guide member having a small volume as much as possible, thereby disposing the guide member in the form of the guide cord 45.

And a graduated scale is provided on both the pull string 46 and the dressing so that the general position of the pH test strip 41 within the test channel 5 can be determined. The moisture-displaying card 6 is used for measuring the humidity value in the detection channel 5, and then reflects the humidity condition of the wound through the humidity value in the detection channel 5, the moisture-displaying card 6 is also fixedly connected by the traction rope 46, and the two ends of the detection channel 5 are sealed under the normal state, so that the detection space is not influenced by the external environment. The humidity display card 6 is not described in detail herein for the prior art.

The plurality of groups of pH test paper 41 are fixedly connected through the hauling rope 46, so that the pH test paper 41 can be moved to a wound position for detection when detection is needed, and moved to other positions after detection is finished, and direct contact between the wound and the drug applying part 3 can not be influenced.

As shown in fig. 1 and 5, the system further includes a detection portion 7, the detection portion includes an infrared temperature measurement unit 73, an image acquisition unit and a display panel 74, the image acquisition unit includes a camera 71 and a light supplement lamp 72, the light supplement lamp 72 is used for illuminating a target area when the camera 71 acquires a picture of the state display portion, and the display panel 74 is used for displaying a temperature, a humidity and a pH value. The camera 71 is used for collecting the image information of the pH test paper 41 or the humidity indicator card 6 after the state change, and then the image information is transmitted to a processor in the detection part to obtain the pH value and the humidity value. The infrared temperature measurement unit 73 can detect the temperature state of the wound in time, and therefore the pH value and the temperature and humidity value are displayed on the idle panel to be judged and determined by medical staff.

The temperature can be used as a reliability index for judging whether the wound surface is infected and the blood flow of the wound surface, and the temperature rise generally indicates that the wound surface is infected. The humidity is also a reaction index of the wound environment, and the proper humidity environment is favorable for keeping the cell activity and promoting the cell regeneration, can also enhance the functions of immune cells, particularly leucocytes, and quickens the migration speed of epidermal cells so as to promote the healing of wounds. Therefore, the state of the wound can be more conveniently mastered by detecting the indexes, the appropriate dressing change time is determined, the pain of a patient is conveniently relieved, and the normal recovery of the wound is ensured.

The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
