Description

Technical Field

[0001] The utility model relates to the field of medical care appliances, in particular to a dressing pad for fixing a drainage tube. Background Art

[0002] The drainage therapy technology used in clinical practice is an effective treatment technology that guides pus, blood and other fluids accumulated in human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. In clinical drainage therapy, one end of the drainage tube is placed in the patient's body or the wound drainage site, and the other end is connected to a drainage bag or other external suction device to drain outwards through internal pressure, gravity or external suction.

[0003] When using the drainage tube, it is necessary to fix the drainage tube on the patient's skin. In clinical practice, the drainage tube is generally fixed on the patient's skin with 3M tape. However, in the actual operation of drainage treatment, it is found that the above fixing method has the following disadvantages:

[0004] 1. The 3M tape used in clinical practice is too narrow to cover a small bonding area and has insufficient stickiness. It is easy to curl and fall off, causing the drainage tube to fail to fix and move.

[0005] 2. In some drainage treatments (such as drainage after lumbar surgery), the drainage tube needs to be fixed to the patient's back with 3M tape. When the patient is resting in bed after surgery, the back is squeezed by the drainage tube for a long time, which can easily cause pressure sores and affect the patient's rest after surgery.

[0006] The applicant has searched the existing drainage tube fixing technology. Among the known existing technologies, the drainage tube is mainly fixed on a large-area fixing patch. For example, the Chinese patent document discloses the name "Anti-pressure sore dressing pad for closed chest drainage tube", publication number CN 21807062 U, publication date March 14, 2023, the name "An integrated drainage tube fixing anti-pressure sore patch", publication number CN 215938723 U, publication date March 4, 2022, the name "A drainage tube fixing patch", publication number CN 108379715 A, publication date August 10, 2018, the name "A new type of drainage tube fixing device", publication number CN 220125315 U, publication date December 5, 2023, etc. Although this type of technology can solve the technical problem of drainage tube fixation to a certain extent, the effect is biased, mainly manifested as follows:

[0007] 1. During the drainage process, the fixing methods of the above-mentioned technologies have obvious convex structures, especially the drainage tube convex on the outside of the fixing patch, which has poor flatness, making the patient uncomfortable in bed and even easily hurting the patient's skin;

[0008] 2. The fixing patch forms a large area of ​​adhesion on the patient's skin and has no breathable structure, which makes the skin in the area where the fixing patch is adhered poorly breathable. Long-term use can easily cause discomfort to the patient and even bedsores.

[0009] In summary, in view of the technical requirements of clinical drainage tube treatment and the shortcomings of existing technologies, it is necessary to design a drainage tube fixing dressing pad that has good air permeability, flat structure, and can prevent pressure ulcers on the patient's skin to a certain extent. Utility Model Content

[0010] The technical purpose of the utility model is to provide a drainage tube fixing dressing pad with high comfort, good air permeability and flat structure in response to the technical demand for clinical drainage tube fixation.

[0011] The technical purpose of the utility model is achieved through the following technical solutions: a dressing pad for fixing a drainage tube, comprising a dressing layer for being pasted and fixed on the patient's skin;

[0012] The outer side of the dressing layer is bonded with a first solid tube silicone layer and a second solid tube silicone layer, the first solid tube silicone layer and the second solid tube silicone layer have a butt joint on the outer side of the dressing layer, and a through-hole for the drainage tube to pass through is provided between the first solid tube silicone layer and the second solid tube silicone layer at the butt joint;

[0013] The dressing pad is provided with a plurality of air holes, each of which is connected to the dressing layer and the corresponding solid tube silicone layer in the thickness direction;

[0014] In clinical applications, the inner side of the dressing layer is adhered to the corresponding skin of the patient, and the drainage tube placed in the patient passes through the tube-penetrating hole at the joint between the first tube-fixing silicone layer and the second tube-fixing silicone layer.

[0015] The above-mentioned technical measures are aimed at the technical requirements for clinical drainage tube fixation. The inner side of the dressing layer is adhered to the corresponding skin of the patient. The drainage tube placed on the patient passes through the tube-penetrating hole at the joint between the first silicone layer and the second silicone layer. The drainage tube is fixed in a fully buried manner. The drainage tube is not easy to displace and has good stability, which can prevent the drainage tube from being displaced, falling off or even folding when the patient turns over.

[0016] At the same time, a plurality of air holes are arranged on the dressing pad in the thickness direction to connect the dressing layer and the corresponding tube-fixing silicone layer, which has good air permeability and effectively alleviates the discomfort of the patient after sticking the dressing pad. Furthermore, the utility model uses silicone material to fix the drainage tube, which has good flexibility and meets the technical requirements of clinical use.

[0017] The outer side of the first tube-fixing silicone layer is provided with a first adhesive groove with an inwardly concave structure near the joint; the air vents provided on the first tube-fixing silicone layer are formed in the area other than the first adhesive groove;

[0018] The outer side of the second tube-fixing silicone layer is provided with a second adhesive groove with an inwardly concave structure near the joint; the air vents provided on the second tube-fixing silicone layer are formed in the area other than the second adhesive groove;

[0019] When the drainage tube passes through the tube penetration hole at the joint between the first and second solid tube silicone layers, a sealing tape is connected to the first and second solid tube silicone layers on the outside of the joint, and the sealing tape connects the first and second solid tube silicone layers at the outside of the joint, and one side edge of the sealing tape is in the first adhesive groove of the first solid tube silicone layer, and the other side edge of the sealing tape is in the second adhesive groove of the second solid tube silicone layer.

[0020] The above-mentioned technical measures respectively provide adhesive grooves with concave structures on the outer sides of the first and second solid tube silicone layers, near the joints. On the basis of fixing the drainage tube in a fully buried manner, sealing tape is used to cover and stick the joints to connect the first and second solid tube silicone layers as a whole, thereby reinforcing the buried structure of the drainage tube and further improving the reliability of preventing displacement of the drainage tube.

[0021] The adhesive groove 1 on the first tube-fixing silicone layer is formed on the outer surface of the first tube-fixing silicone layer in an arc-shaped concave structure;

[0022] The second adhesive groove on the second tube-fixing silicone layer is formed on the outer surface of the second tube-fixing silicone layer in an arc-shaped concave structure.

[0023] On the one hand, the above technical measures make the edge of the sealing tape located inside the concave viscose groove, reducing the relative contact friction with the human body or bed, making curling less likely to occur and having good stability; on the other hand, the molding structure of the viscose groove is relatively flat and has no sharp edges, which is conducive to improving the comfort of patients wearing it.

[0024] The end surface of the butt joint formed by the first solid tube silicone layer is a C-shaped structure;

[0025] The end surface of the butt joint formed by the second solid tube silicone layer is a C-shaped structure.

[0026] The first tube-fixing silicone layer and the second tube-fixing silicone layer are integrally formed on the inner side of the butt joint.

[0027] The above technical measures ensure that the drainage tube is installed and fixed in the tube penetration hole. At the same time, the inner sides of the tube-fixing silicone layer 1 and the tube-fixing silicone layer 2 adopt an integrated molding structure. The molding structure of the tube-fixing silicone layer 1 and the tube-fixing silicone layer 2 on the dressing layer is more stable and not prone to cracking and deformation.

[0028] The outer edge of the first solid tube silicone layer and / or the second solid tube silicone layer is a smoothly transitioned bevel structure, and the outer edge of the bevel is adjacent to the outer surface of the dressing layer.

[0029] The above technical measures are formed with a smoothly transitioned beveled edge structure without affecting the fixation of the drainage tube, which reduces overly protruding edges and corners, and is conducive to improving the wearing comfort of the patient. When the patient is resting in bed, the smoothly transitioned beveled edge structure effectively avoids injuries to the patient.

[0030] The dressing layer is a foam dressing structure. This technical measure uses the material of the foam dressing to fit the patient's skin, which is comfortable and helps reduce the risk of pressure sores.

[0031] A silicone adhesive layer is formed on the inner side of the dressing layer;

[0032] The inner side of the silicone adhesive layer is connected with a peelable release paper layer.

[0033] The above technical measures use silicone adhesive, which has high viscosity and is not easy to curl or fall off. It adopts a peelable release paper layer structure, which has the technical characteristics of flexible use, simple structure and convenient operation.

[0034] The beneficial technical effect of the utility model is as follows: the above technical measures are aimed at the technical requirements of clinical drainage tube fixation, and the inner side of the dressing layer is pasted on the corresponding skin of the patient. The drainage tube placed on the patient passes through the tube-through hole at the joint between the first and second silicone layers of the fixed tube. The drainage tube is fixed by a fully buried method and reinforced with a sealing tape. The drainage tube is not easy to displace and has good stability, which can prevent the drainage tube from being displaced, falling off or even folding when the patient turns over. At the same time, air holes are arranged on the dressing pad, which has good air permeability during use and can effectively alleviate the discomfort of the patient after sticking the dressing pad. The smoothly transitioned bevel structure of the dressing pad is conducive to improving the comfort of the patient's wearing and reducing pressure sores on the patient's skin.

[0041] See also Figure 1 , Figure 2 and Figure 3 As shown, a dressing pad for fixing a drainage tube comprises a dressing layer 1, a tube fixing silicone layer 1 2 and a tube fixing silicone layer 2 3.

[0042] Specifically, the dressing layer 1 is a foam dressing structure, which is attached to the patient's skin using a material similar to a foam dressing, thereby improving comfort and reducing the occurrence of pressure sores. A silicone adhesive layer 11 is formed on the inner side of the dressing layer 1. The silicone adhesive layer 11 has strong viscosity and can be well attached to the patient's skin. A peelable release paper layer 12 is connected to the inner side of the silicone adhesive layer 11. When fixing the drainage tube, the medical staff peels off the release paper layer 12 and attaches the inner side of the silicone adhesive layer 11 to the patient's skin.

[0043] The outer side of the dressing layer 1 is bonded with a solid tube silicone layer 1 2 and a solid tube silicone layer 2 3. The outer edges of the solid tube silicone layer 1 2 or the solid tube silicone layer 2 2 are all smooth transition bevel structures, and the outer edges of the bevels are close to the outer surface of the dressing layer 1. The intersection of the solid tube silicone layer 1 2 and the solid tube silicone layer 2 3 has a butt joint 7, and the end face of the butt joint 7 on the solid tube silicone layer 1 2 or the solid tube silicone layer 2 3 is a C-shaped structure. The end face of the C-shaped structure of the solid tube silicone layer 1 2 (i.e., the butt joint 7) and the end face of the C-shaped structure of the solid tube silicone layer 2 3 form a through-hole 6 for the drainage tube 8 to pass through. The inner side of the butt joint 7 of the solid tube silicone layer 1 2 or the solid tube silicone layer 2 3 is an integrated structure with a flat structure, which effectively prevents the solid tube silicone layer 1 2 or the solid tube silicone layer 2 3 from cracking on the outer side of the dressing layer 1.
