[0001] The utility model belongs to the field of medical consumables, and specifically relates to a disposable absorbable antibacterial dressing. Background Art
[0002] Tracheotomy and intubation is a common surgical procedure used for critically ill patients in clinical medical work. It is a treatment measure to solve insufficient ventilation or breathing difficulties by cutting open the patient's cervical trachea and inserting a metal tracheal tube and a silicone cannula. It is referred to as "tracheotomy".
[0003] Many patients who have undergone tracheotomy in the intensive care unit often have a large amount of purulent exudate during wound care. Generally, the incision dressing is changed twice or more per patient a day. However, the exudate from the incision often exceeds the adsorption limit of the gauze, causing local pressure wounds, dermatitis, malodor, etc. Utility Model Content

The silver ion antibacterial layer is in direct contact with the patient's wound, which can play an antibacterial and anti-inflammatory role. The graphene sponge layer can absorb a large amount of exudate and reduce the risk of infection and pressure wounds.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A disposable absorbable antibacterial dressing, comprising:
[0007] A gauze layer, a graphene sponge layer and a silver ion antibacterial layer are stacked in sequence from top to bottom to form a dressing as a whole, a first slit is cut from the midpoint of one side edge of the dressing toward the center of the dressing, and two second slits are cut from the inner end of the first slit to both sides.
[0008] The above technical solution, its principle and technical effect:
[0009] The dressing composed of the gauze layer, the graphene sponge layer and the silver ion antibacterial layer is split apart to both sides along the first slit, and the tracheostomy cannula is inserted between the joint of the tracheostomy cannula and the wound skin of the patient. The tracheostomy cannula enters from the first slit to the intersection of the first slit and the second slit. At this time, the tracheostomy cannula is surrounded by the gauze layer and the graphene sponge layer, and the dressing is located between the joint of the tracheostomy cannula and the wound skin of the patient. The silver ion antibacterial layer is in direct contact with the patient's wound, which can play an antibacterial and anti-inflammatory role. The graphene sponge layer can absorb a large amount of exudate and reduce the risk of infection and pressure wound.
[0010] Furthermore, the gauze layer, the graphene sponge layer and the silver ion antibacterial layer are adhesively connected.
[0011] Furthermore, at least one button is fixedly connected to the upper surface of the gauze layer and located on one side of the first slit, and the other side of the first slit has connecting belts with the same number as the buttons, one end of the connecting belt is fixedly connected to the upper surface of the gauze layer, and the other end is provided with a through hole for the button to pass through.

[0031] According to the concept of this application, Figures 1 to 3 To describe an embodiment of a disposable adsorbable antibacterial dressing. Specifically, the disposable adsorbable antibacterial dressing is constructed as a split structure, which has components such as a gauze layer 1, a graphene sponge layer 2, and a silver ion antibacterial layer 3. Through the mutual cooperation of the first slit 4, the second slit 5 and other structures, the dressing composed of the gauze layer 1, the graphene sponge layer 2 and the silver ion antibacterial layer 3 is opened to both sides along the first slit 4, and the tracheostomy cannula is inserted between the joint of the tracheostomy cannula and the wound skin of the patient.

At this time, the tracheostomy cannula is surrounded by the gauze layer 1 and the graphene sponge layer 2, and the dressing is located between the joint of the tracheostomy cannula and the wound skin of the patient. The silver ion antibacterial layer 3 is in direct contact with the patient's wound, which can play an antibacterial and anti-inflammatory role. The graphene sponge layer 2 can absorb a large amount of exudate and reduce the risk of infection and pressure wound.
[0032] like Figure 1-3 As shown, a disposable absorbable antibacterial dressing comprises:
[0033] The gauze layer 1, the graphene sponge layer 2 and the silver ion antibacterial layer 3 are stacked in sequence from top to bottom to form a dressing as a whole, a first slit 4 is cut from the midpoint of one side edge of the dressing toward the center of the dressing, and two second slits 5 are cut from the inner end of the first slit 4 to both sides.
[0034] When in use, the dressing composed of the gauze layer 1, the graphene sponge layer 2 and the silver ion antibacterial layer 3 is broken apart to both sides along the first slit 4, and the tracheostomy cannula is inserted between the joint of the tracheostomy cannula and the wound skin of the patient. The tracheostomy cannula enters from the first slit 4 to the intersection of the first slit 4 and the second slit 5. At this time, the tracheostomy cannula is surrounded by the gauze layer 1 and the graphene sponge layer 2, and the dressing is located between the joint of the tracheostomy cannula and the wound skin of the patient. The silver ion antibacterial layer 3 is in direct contact with the patient's wound, which can play an antibacterial and anti-inflammatory role. The graphene sponge layer 2 can absorb a large amount of exudate to reduce the risk of infection and pressure wounds.
[0035] Graphene sponge is a macroscopic three-dimensional solid network of graphene that is further constructed by using two-dimensional graphene sheets, mainly including sponges and aerogels. This three-dimensional graphene nanomaterial not only retains the inherent properties of graphene, but also obtains excellent performance due to the assembled three-dimensional special structure. For example, at extremely low density, it exhibits high specific surface area, porous structure (micropores, mesopores, macropores) and high strength, which is of great significance for maintaining the structural properties of graphene and improving the utilization rate of graphene in practical applications. In addition, in practical applications, three-dimensional materials are more convenient to operate and faster to recycle than two-dimensional materials. Graphene sponge has very good adsorption capacity and is an excellent material for treating organic pollutants. The adsorption capacity of graphene sponge is much higher than that of traditional adsorption materials (generally only about 10 times its own weight of liquid), and the adsorption rate can reach 600 times, that is, 1g of such sponge can absorb more than 600g of liquid. And after 10 cycles, the adsorption rate remains unchanged.
[0036] In one embodiment of the present invention, the gauze layer 1, the graphene sponge layer 2 and the silver ion antibacterial layer 3 are connected by adhesive bonding. The glue can be acrylic glue, etc. This glue is a polymer and a safe glue that does not contain toxic and harmful substances. This glue has good viscosity and air permeability, is suitable for various skin types, and is relatively safe and environmentally friendly. Of course, in some embodiments, the gauze layer 1, the graphene sponge layer 2 and the silver ion antibacterial layer 3 are integrally formed.
[0037] In one embodiment of the present invention, at least one button 6 is fixedly connected to the upper surface of the gauze layer 1 and located on one side of the first slit 4, and a connecting belt 7 having the same number as the buttons 6 is provided on the other side of the first slit 4, one end of the connecting belt 7 is fixedly connected to the upper surface of the gauze layer 1, and the other end is provided with a through hole for the button 6 to pass through. After the dressing is applied, the button 6 is passed through the through hole on the connecting belt 7, so that the button 6 and the connecting belt 7 are connected together, so that the first slit 4 can be bound, and the first slit 4 is prevented from diverging to both sides, so that the dressing is separated from the tracheostomy tube.
[0038] In one embodiment of the present invention, the button 6 and the connecting belt 7 are made of soft silicone material. The soft silicone material can be deformed and bent along with the patch when the patch is used, and has strong applicability.
[0039] In one embodiment of the present invention, the top of the button 6 is an umbrella-shaped structure. The diameter of the umbrella-shaped structure is slightly larger than the inner diameter of the perforation. When the button 6 is inserted into the perforation, the umbrella-shaped structure at the top of the button 6 passes through the perforation, which can further prevent the button 6 from being separated from the perforation on the connecting belt 7, thereby enhancing the connection ability.
[0040] In one embodiment of the utility model, a protrusion 8 is fixedly connected to the upper surface of the gauze layer 1 and located on both sides of the gap, and a through hole 9 is opened at the upper end of the protrusion 8, and a detachable and connected bandage 10 is passed through the through hole 9. After the dressing is applied, the protrusions 8 on both sides are aligned with the holes on both sides of the connector on the tracheostomy tube, and the protrusions 8 are inserted into the holes. After the two ends of the bandage 10 are passed through the through holes 9, they are wrapped around the back of the patient's neck and tied to achieve wearing and fixing.
[0041] In one embodiment of the present invention, one end of the strap 10 is fixedly connected with a buckle 11. When in use, the other end of the strap 10 passes through the through holes 9 on the two protrusions 8 in sequence, and then returns to pass through the buckle 11. The strap 10 is worn and fastened by the fastening of the buckle 11. Such a design can also adjust the tightness of the strap 10. In some embodiments, the strap 10 can be made of an antibacterial material.
