The product is strictly sterilized by high temperature and high pressure, so it is required as a base material for dressing or covering a wound. Medical gauze can be divided into pure cotton gauze and non-woven fabric. Pure cotton gauze has the advantages of natural fibers, namely soft, comfortable and good water absorption, while non-woven fabric is more breathable and wear-resistant, etc.

[0003] In the process of dressing and covering a patient's wound, the current gauze structure or the gauze used in the dressing has a relatively single function. For a small wound, only one or two layers of gauze need to be applied. When blood oozes from the wound, medical staff can directly see the blood oozing situation. However, for a large wound, at least three layers of gauze need to be stacked and covered outside the patient's wound. It is difficult to directly and timely observe whether there is blood absorption in the gauze. Usually, it is only when the blood penetrates and smudges to the outermost gauze covering piece that it can be observed. Therefore, it is difficult to immediately understand the blood oozing situation of the patient's wound, which is not conducive to the care of the patient's wound. Summary of the Invention

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: A medical gauze structure with a blood seepage detection function, comprising: Gauze, provided with multiple layers; A detection module, arranged on the gauze through a connecting member, for obtaining the blood penetration rate of the gauze layer where it is located; An auxiliary pasting component, connected to the gauze, for restricting the displacement change amount of the gauze; Among them, the detection module includes a blood sensing module and a signal receiving module. At least one signal receiving module is pre-matched with the blood sensing module, and the blood sensing module is electrically connected to the signal receiving module.

[0019] More specifically, the connecting member is an adhesive member, and the blood sensing module is adhered to the gauze through the adhesive member.

[0020] In a specific implementation manner, the blood sensing module can be installed and disassembled by the operator himself, which greatly increases the recycling utilization rate and convenience of the blood sensing module.

[0021] More specifically, the auxiliary attachment component is a medical tape, and the gauze is fixed to the wound surface through the medical tape.

[0022] More specifically, the blood sensing module is an NFC tag, and the NFC tag is detachably connected to the side of the gauze close to the skin through a connecting piece.

[0023] More specifically, the signal receiving module includes a memory, a processor, and a computer program stored in the memory and executable on the processor.

[0024] In a specific embodiment, a method for using a medical gauze structure with a blood seepage detection function includes the following steps: Step 1, preset at least three layers of gauze according to the wound surface, and use the first two layers as the gauze dressing layer, and the remaining layers of gauze as the gauze detection layer; Step 2, bond NFC tags on each gauze detection layer, match the NFC tags on each gauze detection layer with the corresponding signal receiving module, and fix the gauze dressing layer and the gauze detection layer to the wound surface through a medical tape; Step 3, use an electronic device equipped with a signal receiving module to approach the gauze detection layer to obtain the blood penetration signal of the gauze detection layer where the blood sensing module is located. If there is no signal on this gauze detection layer, it means that the NFC tag on this gauze detection layer is stained with blood; Step 4. According to the signal emission situation of the NFC tags on each gauze detection layer, obtain the depth of blood seepage and infection of the wound, so as to obtain the blood seepage degree of the wound surface for the gauze.

[0025] In this embodiment, by setting NFC tags on the detection layers of multiple layers of gauze and using the signal receiving module to obtain the blood penetration signal, it can be accurately known whether each layer of the gauze detection layer is stained with blood. According to the signal emission situation of the NFC tags on each layer of the gauze detection layer, the depth of blood seepage and infection of the wound can be accurately obtained, so as to obtain the blood seepage degree of the wound surface for the gauze. It provides very intuitive and accurate data for medical staff, helps to more accurately judge the blood seepage condition of the wound, so as to take corresponding treatment or nursing measures in time; After the wound is bandaged, as long as an electronic device equipped with a signal receiving module is used to approach the gauze detection layer, the current blood seepage information can be quickly obtained, which allows medical staff to know at any time whether the blood seepage of the wound has worsened or improved, without having to frequently remove the gauze for inspection, reducing unnecessary interference to the wound, and at the same time improving the efficiency of medical work; The blood sensing module can be installed and disassembled by the operator himself, which greatly increases the recycling rate and convenience of the blood sensing module. In the actual medical scenario, when it is necessary to replace or adjust the gauze, the blood sensing module can be conveniently removed for reuse, which not only saves medical costs but also makes the whole operation process more flexible and simple, without affecting the normal gauze replacement process due to the difficulty of disassembling the module; The auxiliary patch component uses medical tape, which can firmly fix the gauze to the wound surface. Medical tape is a common and easy-to-use medical supply with good adhesion performance, which can effectively limit the displacement change of the gauze, ensure that the gauze maintains a proper position on the wound, which is beneficial to the normal healing of the wound and can also ensure that the detection module can accurately perform its blood seepage detection function, without inaccurate detection caused by gauze displacement; This medical gauze structure and its usage method integrate the blood seepage detection function into the conventional gauze dressing process, enabling medical staff to simultaneously monitor the blood seepage situation during wound care. Compared with the traditional method of only observing the blood seepage degree of the gauze by the naked eye or regularly disassembling the gauze for inspection, this integrated design greatly optimizes the wound care process, saves the time and energy of medical staff, and enables them to focus more attention on the targeted treatment of the wound; Since the operation of frequently disassembling the gauze to check the blood seepage situation is reduced, the stimulation and interference to the patient's wound are also reduced, the patient's pain perception is reduced, and it helps to improve the comfort of the patient during wound healing. At the same time, more accurate blood seepage monitoring enables medical staff to timely adjust the treatment plan to ensure that the wound can heal in a suitable environment, thereby improving the patient's recovery effect.

[0029] In the present invention, the anti-exudation hemostatic cotton yarn pad 8 includes an anti-seepage blood-absorbing cotton yarn sheet 801 and a pressing and stabilizing canvas sheet 802. The anti-seepage blood-absorbing cotton yarn sheet 801 and the pressing and stabilizing canvas sheet 802 are superposed and overlapped, and the anti-seepage blood-absorbing cotton yarn sheet 801 is arranged on the side close to the contact gauze pad 9; The contact gauze pad 9 includes a wound contact cotton gauze sheet 901 and a contact drug dressing 902. The contact drug dressing 902 is attached to the side of the wound contact cotton gauze sheet 901 away from the blood seepage absorption cotton spun gauze sheet 10; The detection sheet contact non-woven fabric sheet 11 includes an upper lining non-woven fabric sheet 1101 and a lower lining non-woven fabric sheet 1102. The upper lining non-woven fabric sheet 1101 and the lower lining non-woven fabric sheet 1102 are respectively overlapped with the blood seepage absorption cotton spun gauze sheet 10 and the anti-seepage blood-absorbing cotton yarn sheet 801; the blood seepage absorption cotton spun gauze sheet 10, the anti-exudation hemostatic cotton yarn pad 8, the wound contact cotton gauze sheet 901 and the detection sheet contact non-woven fabric sheet 11 are all made of pure cotton material; More specifically, by setting the upper lining non-woven fabric sheet 1101 and the lower lining non-woven fabric sheet 1102, the non-woven fabric material is more conducive to the contact of the structure insertion, and it has less resistance compared with the cotton spun gauze sheet.

[0030] In the present invention, the attaching misalignment angle groove group 2 includes a bifurcated round groove 201 and a misaligned split groove 202.

[0031] In the present invention, the alignment sliding and inserting auxiliary welt 14 includes an alignment cone piece 1401, an alignment anti-sticking convex edge 1402, and an anti-sticking arc groove 1403. The two sides of the alignment cone piece 1401 are respectively fixedly connected to the detection sheet inserting support frame 12 and the anti-sticking arc groove 1403. The cross-section of the alignment cone piece 1401 is in a conical shape with a larger thickness on the side close to the detection sheet inserting support frame 12 than on the other side. The alignment anti-sticking convex edge 1402 coincides with the end of the alignment cone piece 1401, and the alignment anti-sticking convex edge 1402 is in a semi-cylindrical structure. The anti-sticking arc groove 1403 is formed at the ends of the alignment cone piece 1401 and the alignment anti-sticking convex edge 1402 and is in a convex arc shape. Both the alignment cone piece 1401 and the alignment anti-sticking convex edge 1402 are made of silica gel material; More specifically, by setting both the alignment cone piece 1401 and the alignment anti-sticking convex edge 1402 to be made of silica gel material, it not only makes the alignment and sliding and inserting processes more convenient, but also ensures the safety of the material. Moreover, the flexible silica gel can be appropriately bent to avoid pressing on the patient's wound.

[0032] In the present invention, the holding and pulling film mechanism 17 includes a pulling and holding rubber strip 1701 and an anti-slip-off wire groove 1702.

The ends of the main support inclined strip 1801 and the side support inclined strips 1802 are fixedly connected to the inner corner parts of the detection sheet inserting support frame 12; More specifically, by setting the ends of the main support inclined strip 1801 and the side support inclined strips 1802 to be fixedly connected to the inner corner parts of the detection sheet inserting support frame 12, the stability of the exposed NFC coil sheet 13 is improved, making it not easily damaged.

[0033] A method for using a medical gauze structure with a blood oozing detection function includes the following steps: S1: Hold the plugging and supporting mechanism, and then insert the detection sheet inserting support frame 12 and the exposed NFC coil sheet 13 into the detection sheet inserting rubber frame 7 and push them in, so that the detection sheet inserting support frame 12 and the exposed NFC coil sheet 13 are inserted between the two detection sheet contact non-woven fabric sheets 11; S2: Then align the contact gauze pad 9 with the wound part of the patient, and attach the frame-shaped dressing base sheet 1 to the body surface at the edge of the patient's wound; S3: After finally sticking to the patient's wound, the exposed NFC coil sheet 13 provides external detection signals. If there is blood oozing out, the blood infiltrates the contact gauze pad 9, the blood oozing absorption cotton gauze sheet 10 and the detection sheet contact non-woven fabric sheet 11, so that the exposed NFC coil sheet 13 can be in contact with blood, and the conductive metal ions in the blood can contact with the exposed NFC coil sheet 13, which will cause the exposed NFC coil sheet 13 to short-circuit and fail to provide external signal detection, that is, to detect the bleeding situation.

[0034] In the present invention, in step S1, when the detection sheet plug-in support frame 12 and the bare NFC coil sheet 13 are inserted between the two detection sheet contact non-woven fabric sheets 11, it is necessary to place the side of the bare NFC coil sheet 13 that is not blocked by the supporting structure on the side close to the contact gauze pad 9; More specifically, by setting a contact structure between two detection sheets contacting the non-woven fabric sheets 11 as a detection sheet plug-in support frame 12 and an exposed NFC coil sheet 13 for insertion, the detection sheet contacting the non-woven fabric sheet 11 and being worn out can be avoided because the non-woven fabric is more wear-resistant than cotton yarn.

[0035] Working principle: When bandaging and covering the wound and detecting bleeding, hold the plug-in support mechanism (connecting the plastic rod 15, the overlapping rubber strip 16 and the holding and pulling rubber sheet mechanism 17), and then insert the detection sheet plug-in support frame 12 into the detection sheet insertion rubber frame 7 through the alignment of the positioning sliding auxiliary strip 14, so that the detection sheet plug-in support frame 12 and the exposed NFC coil sheet 13 are pushed and inserted between the two detection sheet contact non-woven fabric sheets 11; then tear the release film sealing sheet 4 from the frame-type application substrate 1 to expose the contact gauze pad 9, and then align the contact gauze pad 9 with the patient's wound part, and attach the frame-type application substrate 1 to the patient's body surface at the edge of the wound, the corners of the frame-type application substrate 1 can be adjusted, and the bifurcation is achieved by attaching the staggered corner groove group 2 and the staggered middle groove group 3, so that it is more in line with the patient's uneven body surface around the wound, so as to achieve bandaging and covering; There is no bleeding in the wound of the exposed NFC coil sheet 13 to provide an external detection signal. If blood seeps out and penetrates the detection sheet contact non-woven fabric sheet 11, the exposed NFC coil sheet 13 can be in contact with the seeping blood, and the conductive metal ions in the blood contact the exposed NFC coil sheet 13, causing the exposed NFC coil sheet 13 to short-circuit and fail to provide external signal detection, so that it can be detected immediately that the blood has penetrated into the exposed NFC coil sheet 13.
