[0004] However, when using the above-mentioned dressing, the drainage tube needs to be passed through the dressing and then fixed. The drainage tube may be contaminated during the process of passing through the dressing. In addition, when changing the dressing of the patient's wound, the dressing needs to be torn off the patient's skin and then changed. This repetitive process will cause the edge of the dressing to flip up, and in severe cases, the dressing will fall off. At the same time, it has no reminder function. It is difficult for patients and medical staff to grasp the replacement time of the dressing with indwelling drainage tube. The replacement of the dressing depends entirely on experience. Utility Model Content

[0005] The present invention aims to overcome the problems in the prior art mentioned above, such as the need to pass the drainage tube through the dressing and then fix it during use, the possibility of the drainage tube being contaminated during the process of passing through the dressing, and the need to tear the dressing off the patient's skin and then change the dressing when changing the patient's wound, which may cause the edge of the dressing to flip up, and in severe cases, the dressing may fall off, and the invention has no reminder function, making it difficult for patients and medical staff to grasp the replacement time of the dressing with the indwelling drainage tube, and the replacement of the dressing depends entirely on experience.

[0006] A drainage port dressing is proposed, comprising a drainage tube, a first non-woven fabric, a second non-woven fabric, a fixing patch, an absorbent gauze, a water-discoloring layer, and a waterproof breathable membrane.

[0007] In the technical solution of the present invention, a groove is provided on the first non-woven fabric, so when fixing the drainage tube, it is only necessary to open the groove on the first non-woven fabric, and then place the drainage tube inside the first non-woven fabric, thereby avoiding the first non-woven fabric and the medical breathable net from contaminating the drainage tube, and the first non-woven fabric is adhered to the patient's skin, the second non-woven fabric is adhered to the first non-woven fabric, and the medicine is placed on the medical breathable net of the first non-woven fabric to have an effect on the patient's wound, so when changing the dressing, it is only necessary to open the second non-woven fabric to change the dressing for the patient, and there is no need to replace the first non-woven fabric. Therefore, there is no need to repeatedly tear off the first non-woven fabric, thereby avoiding the possibility of the dressing falling off, and at the same time, a water-discoloring layer is provided on the second non-woven fabric, and the water-discoloring layer is directly connected to the absorbent gauze. In direct contact, when the absorbent gauze is oversaturated, the water-discoloring layer will come into contact with the exudate on the absorbent gauze, and then the water-discoloring layer will change color, which is used to remind medical staff that the absorbent gauze needs to be replaced at this time, thereby avoiding wound contamination caused by exudate, and is used to solve the problem mentioned in the technical background that the drainage tube needs to be passed through the dressing and then fixed during use. The drainage tube may be contaminated during the process of passing through the dressing, and when changing the dressing on the patient's wound, the dressing needs to be torn off the patient's skin, and then the dressing is changed. This reciprocating process will cause the edge of the dressing to flip up, and in severe cases, the dressing will fall off. At the same time, it does not have a reminder function, and it is difficult for patients and medical staff to grasp the replacement time of the indwelling drainage tube dressing. The replacement of the dressing depends entirely on experience.

[0008] In the preferred technical solution of the present invention, a pad is provided at the center position of the fixing patch, and the drainage tube is placed on the pad. After the pad is placed on the pad, the drainage tube and the first non-woven fabric can be fixed together through the fixing patch. Subsequently, after the first non-woven fabric is stuck to the patient's skin, it can be ensured that when the external drainage tube shakes, the drainage tube inside the first non-woven fabric will not shake, thereby avoiding pulling the patient's wound.

[0009] In the preferred technical solution of the present invention, a medical breathable net is connected to the center of the first non-woven fabric, the absorbent gauze is placed on the medical breathable net, the medicine and the absorbent gauze are placed on the medical breathable net, the exudate can flow out through the air holes of the medical breathable net and then be absorbed by the absorbent gauze, and the absorbent gauze and the wound are separated by the medical breathable net. Therefore, when replacing the absorbent gauze, the absorbent gauze will not pull the patient's wound, thereby reducing the patient's pain.

[0010] In the preferred technical solution of the present invention, grooves are provided on one side of the first non-woven fabric, medical breathable mesh, absorbent gauze and waterproof breathable membrane. After the grooves are opened, the drainage tube can enter the center of the first non-woven fabric through the grooves, eliminating the previous method of the drainage tube passing through the middle of the dressing, thereby reducing the possibility of contamination of the drainage tube.

[0011] In the preferred technical solution of the present invention, the waterproof and breathable membrane is arranged on the outside of the absorbent gauze. After the waterproof and breathable membrane comes into contact with the skin, the exudate can only remain in the center of the waterproof and breathable membrane due to the characteristics of the waterproof and breathable membrane, and cannot flow out through the patient's skin, thereby avoiding the possibility of the exudate polluting the external environment.

[0012] Preferably, an adhesive layer is provided at the slots of the first non-woven fabric and the waterproof breathable membrane, and the adhesive layer connects the slots of the first non-woven fabric and the waterproof breathable membrane together to form a whole, thereby avoiding the possibility of leakage of exudate from the slots.

[0013] In the preferred technical solution of the present invention, an opening is provided at the center of the second non-woven fabric, and the water-changing layer is bonded to the opening of the second non-woven fabric. After the absorbent gauze is oversaturated, the water-changing layer will come into contact with the exudate inside the absorbent gauze, thereby changing color, thereby reminding medical staff that the absorbent gauze is oversaturated and needs to be replaced.

[0014] Preferably, the surfaces of the first non-woven fabric and the second non-woven fabric are coated with a nano-silver coating, which increases the antibacterial effect of the first non-woven fabric and the second non-woven fabric, thereby minimizing infection of the patient's wound.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model does not need to open the entire dressing when changing the dressing and replacing the absorbent gauze. It only needs to open the second non-woven fabric to change the dressing and replace the absorbent gauze, thereby reducing the possibility of the edge turning up due to multiple openings of the first non-woven fabric, which may cause the first non-woven fabric to fall off in severe cases. At the same time, when fixing the drainage tube, the previous method of passing the drainage tube through the first non-woven fabric and then fixing it is eliminated, thereby reducing the possibility of the drainage tube being contaminated. At the same time, when the absorbent gauze is oversaturated, the water-changing layer will contact the exudate on the absorbent gauze, and then the water-changing layer will change color, which is used to remind medical staff that the absorbent gauze needs to be replaced at this time, thereby avoiding wound contamination caused by excessive exudate.

[0023] The following is a combination of the appended examples of the present invention Figure 1-5 , the technical solutions in the embodiments of the present utility model are described in detail.

[0024] like Figure 1-5 As shown, a drainage port dressing includes a drainage tube 1, a first non-woven fabric 2, a second non-woven fabric 3, a fixing patch 4, an absorbent gauze 5, a water-discoloring layer 6 and a waterproof breathable membrane 7. The first non-woven fabric 2 is provided with an opening at the center thereof, and a medical breathable mesh 21 is arranged at the opening at the center thereof, and the medical breathable mesh 21 is bonded to the first non-woven fabric 2. The medical breathable mesh 21 is located below the first non-woven fabric 2, and a plurality of breathable holes are provided on the medical breathable mesh 21.

[0025] like Figure 1-5As shown, when the first non-woven fabric 2 is attached to the patient's drainage port, the exudate from the drainage port can directly pass through the air holes of the medical breathable mesh 21 and flow out. A through hole is opened at the center of the medical breathable mesh 21, and the drainage tube 1 passes through the through hole and is arranged above the medical breathable mesh 21. Then, after the drainage tube 1 is bent, it is fixed to the first non-woven fabric 2 by the fixing patch 4. The absorbent gauze 5 is located at the center of the first non-woven fabric 2 and is placed on the medical breathable mesh 21.

[0026] like Figure 1-5 As shown, the exudate from the patient's drainage port will be absorbed by the absorbent gauze 5 on the medical breathable mesh 21 after passing through the medical breathable mesh 21, thereby preventing the exudate from continuing to flow out. The fixing patch 4 is located above the first non-woven fabric 2 and is arranged on one side of the first non-woven fabric 2, and the fixing patch 4 is bonded to the first non-woven fabric 2. A pad 41 is provided at the center of the first non-woven fabric 2, and the bottom end of the pad 41 is bonded to the first non-woven fabric 2. An arc-shaped groove is provided at the top of the pad 41.

[0027] like Figure 1-5 As shown, after the drainage tube 1 is bent, it can be placed in the arc-shaped groove at the top of the pad 41, so as to prevent the drainage tube 1 from being blocked at the bend due to excessive downward movement. Therefore, after the drainage tube 1 is placed on the pad 41, the drainage tube 1 can be fixed on the pad 41 using the fixing patch 4. The fixing patch 4 is provided with an adhesive layer, so the fixing patch 4 can be bonded to the first non-woven fabric 2, so as to prevent the drainage tube 1 from falling from the pad 41. The second non-woven fabric 3 is arranged above the first non-woven fabric 2.

[0028] like Figure 1-5 As shown, a corner of the second non-woven fabric 3 is sewn on the first non-woven fabric 2, so the second non-woven fabric 3 can be opened upward relative to the first non-woven fabric 2, and an adhesive layer is provided on the inner surface of the second non-woven fabric 3 in contact with the first non-woven fabric 2, so after the second non-woven fabric 3 is rotated downward, it can be directly adhered to the first non-woven fabric 2 through the adhesive layer. The center position of the second non-woven fabric 3 is also provided with an opening, and the water-discoloring layer 6 is adhered to the through hole at the center position of the second non-woven fabric 3.

[0029] like Figure 1-5 As shown, when the second non-woven fabric 3 rotates downward, the hydrochromic layer 6 will rotate downward synchronously with the second non-woven fabric 3 until the second non-woven fabric 3 is bonded to the first non-woven fabric 2. The hydrochromic layer 6 will also directly contact the absorbent gauze 5. Therefore, when the absorbent gauze 5 is oversaturated, the hydrochromic layer 6 will change color when it comes into contact with the exudate inside the absorbent gauze 5, thereby reminding medical staff that the absorbent gauze 5 is oversaturated and needs to be replaced.

[0030] like Figure 1-5As shown, after the water-chromic layer 6 changes color, when replacing a new absorbent gauze 5, the water-chromic layer 6 can be torn off from the second non-woven fabric 3 at the same time, and then the new water-chromic layer 6 can be bonded to the second non-woven fabric 3. The waterproof breathable membrane 7 is located below the first non-woven fabric 2 and bonded to the first non-woven fabric 2, and the waterproof breathable membrane 7 is located on the outside of the medical breathable mesh 21. After the first non-woven fabric 2 is bonded to the patient's skin, the waterproof breathable membrane 7 will be in direct contact with the patient.

[0031] like Figure 1-5 As shown, the waterproof breathable membrane 7 is circular, so after the first non-woven fabric 2 is attached to the patient's skin, the waterproof breathable membrane 7 will surround the patient's wound. Therefore, after the exudate flows out of the wound, due to the characteristics of the waterproof breathable membrane 7 itself, the exudate will only remain in the center of the waterproof breathable membrane 7.

[0032] like Figure 1-5 As shown, it then flows out through the air holes of the medical gauze 5 and is absorbed by the absorbent gauze 5, thereby preventing the exudate from flowing out from the skin to the surrounding area, contaminating the bed sheet and causing the adhesion of the adhesive layer of the first non-woven fabric 2 to decrease, thereby causing the dressing to fall off the skin. The fixing patch 4 is arranged on one side of the first non-woven fabric 2, and a groove is provided on the other side of the first non-woven fabric 2. The medical breathable mesh 21, the absorbent gauze 5 and the waterproof breathable membrane 7 are also grooved at the position where the groove of the first non-woven fabric 2 is located.

[0033] like Figure 1-5 As shown, and because the medical breathable mesh 21, the absorbent gauze 5 and the waterproof breathable membrane 7 are bonded to the first non-woven fabric 2, when the first non-woven fabric 2 is opened from the slotted position, the first non-woven fabric 2 will drive the medical breathable mesh 21, the absorbent gauze 5 and the waterproof breathable membrane 7 to open synchronously, thereby allowing the guide tube to enter the through hole at the center of the medical breathable mesh 21 from the slotted position. The slots of the first non-woven fabric 2 and the waterproof breathable membrane 7 are both provided with an adhesive layer 8.

[0034] like Figure 1-5 As shown, after the drainage tube 1 is placed inside the through hole at the center of the medical breathable mesh 21, the adhesive layer 8 can be used to bond the open waterproof breathable membrane 7 and the first non-woven fabric 2 together, thereby preventing exudate from seeping out of the opening of the waterproof breathable membrane 7. The surfaces of the first non-woven fabric 2 and the second non-woven fabric 3 are both coated with a nano-silver coating, which increases the antibacterial effect of the first non-woven fabric 2 and the second non-woven fabric 3, thereby minimizing infection of the patient's wound.

[0035] The movement process of this embodiment is as follows: after the first non-woven fabric is opened along the groove, the drainage tube 1 can be placed into the through hole of the medical breathable mesh 21 through the groove, and then the waterproof breathable membrane 7 and the groove of the first non-woven fabric 2 can be bonded together with the adhesive layer 8, and then the first non-woven fabric 2 can be adhered to the patient's skin. When performing this operation, it is necessary to ensure that the groove of the first non-woven fabric 2 and the waterproof breathable membrane 7 is located above the patient's wound to prevent exudate from leaking out of the groove.

[0036] After the first non-woven fabric 2 is bonded to the skin, the drainage tube 1 can be bent and placed on the pad 41. After the drainage tube 1 is placed on the pad 41, the fixing patch 4 can be used to fix the drainage tube 1 and the pad 41 together, and then the absorbent gauze 5 is placed on the medical breathable mesh 21, and then the second non-woven fabric 3 is rotated downward and bonded to the first non-woven fabric 2, and then the water-chromic layer 6 is bonded to the through hole in the center of the second non-woven fabric 3 and ensure that the water-chromic layer 6 is in direct contact with the absorbent gauze 5.

[0037] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
