Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the embodiment, Figure 1 Provided is a novel functional abdominal wall sealing dressing, which may optionally include but is not limited to: a polyurethane covering layer 1;

[0026] The humidity display module layer 2 is provided on the lower end surface of the polyurethane coating layer 1 and is used to detect the humidity of the dressing;

[0027] The dressing hardening layer 3 is provided on the lower end surface of the humidity display module layer 2 and is used to increase the hardness of the dressing;

[0029] The chitosan hemostatic layer 5 is provided on the lower end surface of the polyurethane coating layer 1 and completely covers the humidity display module layer 2, the dressing hardening layer 3 and the temperature and pressure sensor layer 4. The chitosan hemostatic layer 5 is composed of chitosan, polyethylene glycol and methyl methacrylate and is used to stop bleeding from the wound of the injured person;

[0030] The signal transmission component 6 is provided on the polyurethane coating layer 1 and is electrically connected to the humidity display module layer 2 and the temperature and pressure sensor layer 4 respectively, and is used for transmitting monitoring data of the humidity display module layer 2 and the temperature and pressure sensor layer 4.

[0031] In this embodiment, a novel functional abdominal wall sealing dressing of the utility model is provided. The polyurethane coating layer 1 is used to stop bleeding of the injured part of the human body and keep the wound surface clean. The temperature and pressure sensor layer 4 can detect the abdominal cavity pressure of the human body and the temperature of the human body surface. The dressing hardening layer 3 can increase the overall hardness of the dressing, thereby ensuring that the dressing will not be easily deformed under the influence of external force. The humidity display module layer 2 can detect the humidity of the dressing, thereby stopping bleeding of the abdominal injury of the human body, closing the abdominal cavity defect, and detecting the abdominal cavity pressure and temperature to indicate the humidity of the dressing, thereby achieving a better treatment effect on open abdominal wall injuries.

[0033] Preferably, the chitosan nonwoven fabric is dyed with Reactive Blue-225 dye.

[0034] In this embodiment, a preferred embodiment of the humidity display module layer 2 is given. When the chitosan non-woven fabric is saturated with liquid, the liquid will contact the humidity-sensitive ink on the upper end surface of the chitosan non-woven fabric, causing the humidity-sensitive ink to change from white to blue, thereby achieving the effect of monitoring the humidity of the dressing.

[0035] In more detail, the dressing hardening layer 3 in the preferred embodiment of the present invention is made of polystyrene, and a number of air holes are provided on the dressing hardening layer 3 to increase the overall hardness of the dressing.

[0036] In this embodiment, a preferred embodiment of the dressing hardening layer 3 is given. The dressing hardening layer 3 can increase the overall hardness of the dressing, thereby ensuring that the dressing will not be easily deformed under the influence of external force, and the air holes opened on the dressing hardening layer 3 avoid affecting the monitoring effect of the humidity display module layer 2 on the dressing humidity.

[0037] Furthermore, the temperature sensor 41 in the preferred embodiment of the present invention is a miniature NTC probe sensor, which is composed of a bead-shaped thermistor and a lead connected to the bead-shaped thermistor, and is used to detect the temperature of the human body surface; the pressure sensor 42 is composed of a core-shell type piezoresistive pressure sensing yarn and traditional textiles, and is used to detect the intra-abdominal pressure of the human body.

[0038] Preferably, the core-shell piezoresistive pressure sensing yarns of the pressure sensor 42 are alternately placed in the traditional textile in the longitudinal and transverse directions, so that sensing units are formed at the interweaving points of the core-shell piezoresistive pressure sensing yarns.

[0039] Preferably, the temperature sensor 41 is disposed in the traditional textile formed by the pressure sensor 42 , and the transmission leads of the temperature sensor 41 and the pressure sensor 42 are both electrically connected to the signal transmission component 6 .

[0040] In this embodiment, a preferred embodiment of the temperature and pressure sensor layer 4 is provided. The temperature of the injured part of the human body can be monitored by the temperature sensor 41, thereby facilitating better treatment of the injured person. The abdominal pressure of the injured person can be monitored by the pressure sensor 42, thereby preventing the injured person from having excessive intra-abdominal pressure, thereby causing abdominal compartment syndrome.

[0041] Of course, in the actual design process, other types of piezoresistive pressure sensing yarns can also be selected, as long as they can achieve the effect of monitoring intra-abdominal pressure. Other models will not be described here, and those skilled in the art can easily obtain them through existing technology.

[0042] Furthermore, the chitosan hemostatic layer 5 in the preferred embodiment of the present invention is chitosan cross-linked with polyethylene glycol and grafted with sodium polyacrylate, and the chitosan hemostatic layer 5 is sponge-shaped.

[0043] In this embodiment, a preferred embodiment of the chitosan hemostatic layer 5 is given. By placing the chitosan hemostatic layer 5 on the injured abdominal cavity of the human body, the chitosan hemostatic layer 5 can stop bleeding at the injured part and protect the wound surface of the injured person, thereby preventing infection.
