DETAILED DESCRIPTION

[0024] Based on this, in order to improve the problem in the related art that when exudate seeps out of the drainage tube, the antibacterial dressing cannot immediately provide visual feedback, and the medical staff cannot detect the exudate in time, resulting in the drainage tube being dislocated and infected, the embodiments of the present application provide the following solution.

[0025] Please also read Figure 1-Figure 5 , comprising a dressing body 1, a water absorption layer 2, a mesh 3, an antibacterial layer 4, an adhesive strip 5 and a placement layer 6, the antibacterial layer 4 is bonded to the dressing body 1, the adhesive strip 5 is bonded to the antibacterial layer 4, the water absorption layer 2 is bonded to the antibacterial layer 4, the mesh 3 is sewn to the water absorption layer 2, the dressing body 1 is provided with a through hole, the placement layer 6 is bonded in the through hole and abuts against the antibacterial layer 4, the placement layer 6 is provided with a placement cavity 8, the placement cavity 8 is filled with a color developer 7, and the color developer 7 changes color when it comes into contact with water.

[0026] With such arrangement, during the cooperation process of lumbar drainage operation, the medical staff will accurately face and cover the needle hole of the puncture needle and the connection part of the drainage tube with a piece of mesh 3, and then use the sticky characteristics of the adhesive strip 5 to firmly stick it on the patient's waist skin to ensure the stability and safety of the entire drainage system. It can effectively prevent any possible external pollution or liquid leakage. Once the needle hole of the puncture needle or the drainage tube accidentally leaks, the water-absorbing layer 2 can quickly and efficiently absorb the moisture in the exudate and transfer the absorbed moisture to the placement cavity 8 in the placement layer 6. In this placement cavity 8, a special color developer 7 is pre-placed. The color developer 7 is a mixture of bromophenol blue and alkaline powder. When dry and not in contact with moisture, this color developer 7 presents a stable blue crystalline state. However, when the color developer in the placement cavity 8 When the developer 7 encounters water or a humid environment under alkaline conditions, such as water absorbed from exudate, it will immediately undergo a chemical reaction, and the color will change from the original blue to bright yellow or green; the developer 7 can also be a mixture of phenolphthalein blue and alkaline powder or copper phthalocyanine; phenolphthalein blue is colorless in a neutral or acidic environment, but in the presence of an alkaline solution or water, it will turn bright blue; copper phthalocyanine is an organic pigment, usually blue-green, and will change from blue-green to bright red when encountering water; the alkaline powder is one or more of sodium hydroxide, sodium carbonate, and sodium bicarbonate, and this color change can be used to detect the presence of water. This significant color change provides medical staff with an intuitive and reliable basis for judgment, allowing them to quickly detect whether there is an abnormal situation of exudate leakage from the needle hole or drainage tube, so that they can take necessary treatment measures in time. In addition, the main function of the antibacterial layer 4 is to provide an additional protective barrier to effectively prevent patients from being infected by bacteria in the external environment, further ensuring the safety and recovery process of patients.

[0027] Optionally, in some embodiments, please refer to Figure 1-Figure 3 A release paper 9 is bonded to the adhesive strip 5 , and a release ear 10 is bonded to the release paper 9 .

[0028] In this way, the release paper 9 on the adhesive strip 5 is used to protect the stickiness of the adhesive strip 5. When the dressing is not in use, the release paper 9 is adhered to the adhesive strip 5 to prevent the adhesive ability of the adhesive strip 5 from being reduced due to long-term exposure to the air. The release ear 10 makes it convenient for the user to quickly tear off the release paper 9 from the adhesive strip 5.

[0029] Optionally, in some embodiments, please refer to Figure 4 as well as Figure 5The placement cavity 8 of the placement layer 6 is filled with a water-absorbing sponge 11, the water absorption capacity of the water-absorbing sponge 11 is better than that of the water-absorbing layer 2, and the water holding capacity of the water-absorbing sponge 11 is significantly lower than that of the water-absorbing layer 2, and the water-absorbing sponge 11 is in contact with the color developer 7.

[0030] With such arrangement, when leakage occurs in the drainage tube, the water-absorbing layer 2 first contacts the leakage and absorbs the leakage. At this time, the water in the leakage is stored in the water-absorbing layer 2. However, since the water-absorbing capacity of the water-absorbing sponge 11 is better than that of the water-absorbing layer 2, the water stored in the water-absorbing layer 2 is absorbed into the water-absorbing sponge 11. However, the water holding capacity of the water-absorbing sponge 11 is significantly lower than that of the water-absorbing layer 2. Therefore, the water-absorbing sponge 11 will quickly reach a water saturation state and transfer the water to the color developer 7, causing the color of the color developer 7 to change.

[0031] Optionally, in some embodiments, please refer to Figure 1 as well as Figure 5 An annular temperature-sensitive coating 12 is bonded to the through hole of the dressing body 1 , and an information layer 13 is bonded to the dressing body 1 . The information layer 13 includes a writing area 14 and a colorimetric area 15 . The writing area 14 and the colorimetric area 15 are bonded to the information layer 13 .

[0032] In this way, the annular temperature-sensitive coating 12 is designed to tightly surround and fit around the designated placement layer 6. It can closely contact and accurately sense subtle changes in the patient's skin temperature, and it has a highly sensitive response mechanism. When the patient's skin temperature fluctuates, whether the change is a slight increase or decrease, the annular temperature-sensitive coating 12 can instantly capture these temperature differences and automatically present a variety of color changes on the coating surface according to the degree of temperature change. To match this, a colorimetric area 15 is specially set on the information layer 13. This area carefully draws a series of color information corresponding to different body temperatures. Each body temperature accurately corresponds to a specific color block. These color blocks are an intuitive "body temperature palette", which allows staff to quickly and accurately determine the approximate range of the patient's skin temperature at a glance through the colors displayed by the annular temperature-sensitive coating 12. In addition, in order to facilitate recording and management, a writing area 14 is added. This area provides medical staff with ample space to write the patient's number, name, admission date or any other necessary medical information. This design not only greatly improves work efficiency, but also ensures that the information of each patient can be recorded clearly and accurately, thereby providing strong data support in the subsequent diagnosis and treatment process.

[0033] Optionally, in some embodiments, please refer to Figure 5A transparent protective layer 16 is bonded to the annular temperature-sensitive coating 12 and the placement layer 6 .

[0034] With such a configuration, the transparent protective layer 16 plays a vital role in the design. It is firstly known for its excellent transparency, which enables the staff to clearly observe the color changes of the annular temperature-sensitive coating 12 and the color developer 7 inside the placement layer 6 through the protective layer without any hindrance. This high-transparency design not only improves the intuitiveness and accuracy of observation, but also ensures that the staff can instantly capture any subtle color changes, so as to quickly make corresponding medical judgments. In addition to its transparency, the transparent protective layer 16 also undertakes the important task of protecting the color developer 7 from interference from the external environment. Moisture in the air is the natural enemy of many chemical substances, and the color developer 7 is a key component for sensing temperature changes and producing color reactions. Its stability and accuracy are crucial. By effectively isolating moisture in the air, the transparent protective layer 16 It provides a dry and stable working environment for the color developer 7, thereby ensuring the accuracy and reliability of the color change. What is more advanced is that the transparent protective layer 16 also has an excellent thermal insulation effect. This feature means that it can effectively block the direct impact of external temperature fluctuations on the temperature-sensitive coating. Whether it is a sudden increase or decrease in temperature, it will not easily penetrate the protective layer and interfere with the temperature-sensitive coating's accurate perception of the patient's skin temperature. This thermal insulation capability not only improves the stability and durability of the entire system, but also ensures that even in a complex and changeable environment, the temperature-sensitive coating can continue to provide accurate and reliable body temperature monitoring data. The transparent protective layer 16, with its unique transparency, protection and thermal insulation effects, provides a safe and efficient working environment for the annular temperature-sensitive coating 12 and the color developer 7, which is an important guarantee for ensuring the accuracy and reliability of medical monitoring.

[0035] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
