Description

Technical Field

[0001] This invention relates to the field of wound care and wound dressings, and more particularly to a leak-proof combination medical dressing pack. Background Technology

[0002] Currently, most skin wound care dressing packs widely used in clinical practice are single-use designs. Their usage involves completely removing the entire adhesive layer along with the dressing components from the skin each time the dressing is changed, and then reapplying a brand new dressing. For patients with chronic wounds, whose healing periods can last for weeks or even months, this often requires dozens of dressing changes. This means that the skin in the same wound area will repeatedly endure the tearing and re-adhering of the adhesive layer. This frequent process of removal and re-adhering is not only cumbersome and time-consuming, significantly increasing the workload and nursing time of medical staff, but also brings great discomfort to patients. The pain is both physical and psychological. Each time the adhesive layer is removed, the newly formed granulation tissue and crawling epithelial cells are easily damaged by mechanical tearing, causing secondary mechanical damage. In severe cases, it can even lead to the wound tearing and bleeding again, causing the healing process to regress. At the same time, repeated tearing of the adhesive layer will also continuously irritate and damage the healthy skin around the wound, leading to a decline in the skin barrier function and causing complications such as contact dermatitis, maceration, or folliculitis. Frequent dressing changes and pain can easily cause patients to have fear and anxiety, and even develop resistance to wound treatment, thus significantly reducing treatment compliance and affecting the quality of wound healing and long-term prognosis. Summary of the Invention

[0003] To overcome the shortcomings of most skin wound care dressing packs being disposable, requiring frequent tearing and re-pasting for multiple dressing changes, and causing great physical and psychological pain to patients, this invention provides a leak-proof combination medical dressing pack.

[0004] Technical solution: A leak-proof combined medical dressing package includes a breathable patch, a baffle frame, a mesh sheet, absorbent cotton, and a protective patch; the breathable patch has a hollow structure in the middle; a baffle frame for filling the dressing layer is set at the hollow structure in the middle of the breathable patch; a mesh sheet is fixed to the bottom of the baffle frame; an absorbent cotton ring is fixed between the surface of the mesh sheet and the inner wall of the baffle frame; a protective patch is attached to the breathable patch; the protective patch covers the baffle frame.

[0005] Furthermore, a pull tab is fixed to both the front and rear sides of the enclosure frame.

[0006] Furthermore, the central area of ​​the mesh sheet has a perforated structure.

[0007] Furthermore, a layer of protective mesh is provided between the protective patch and the fence frame.

[0008] Furthermore, the mesh sheet is provided with dividing rings, which divide the space above the mesh sheet into an inner dressing area and an outer dressing area.

[0009] Furthermore, the bottom of the mesh sheet is provided with several flow guide grooves.

[0010] Furthermore, the mesh sheet is woven from medical-grade polyester fiber material.

[0011] Furthermore, a liquid collection ring groove is provided at the bottom of the mesh sheet.

[0012] Furthermore, the liquid collection ring groove of the mesh sheet has several through holes that connect to the absorbent cotton.

[0013] Furthermore, a water-retaining ring is provided in the center of the bottom of the breathable patch, and the water-retaining ring is located between the breathable patch and the enclosure frame.

[0014] Compared with existing technologies, the present invention has the following advantages: The present invention provides a leak-proof combined medical dressing pack, in which a breathable patch is attached to the patient's skin. The breathable patch has a replaceable baffle frame and a gauze sheet for holding the dressing layer. A protective patch covers the baffle frame and the dressing layer. During dressing changes, sprayed sterile water passes through the gauze sheet to the wound area of ​​the skin, allowing the gauze sheet to be separated more easily. The dressing change is completed by replacing the baffle frame, gauze sheet, and dressing layer. The gauze sheet also has absorbent cotton to absorb excess sterile water. Combined with a water-blocking ring separating the breathable patch from the baffle frame, this reduces the likelihood of the breathable patch becoming wet and losing its adhesive properties due to liquid leakage. This reduces the frequency of removing and replacing the breathable patch, solving the technical problem that most skin wound care dressing packs are disposable, requiring frequent removal and re-application for multiple dressing changes, causing significant physical pain and psychological trauma to patients. The invention improves the safety, cleanliness, and patient comfort of the dressing change process, while maintaining the integrity, sealing, and adhesive durability of the breathable patch.

Detailed Implementation

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0018] Example 1: A leak-proof combination medical dressing pack according to this example, such as... Figures 1-7 As shown, it includes a breathable patch 1, a fencing frame 2, a mesh sheet 3, absorbent cotton 4, and a protective patch 5; the breathable patch 1 has a hollow structure in the middle; the fencing frame 2 is set at the hollow structure in the middle of the breathable patch 1; a pull tab 201 is fixed to the front and rear sides of the fencing frame 2; the mesh sheet 3 is fixed to the bottom inside the fencing frame 2; a ring of absorbent cotton 4 is fixed to the surface of the mesh sheet 3, and the absorbent cotton 4 is tightly attached to the inner wall of the fencing frame 2; the protective patch 5 is attached to the breathable patch 1; the protective patch 5 covers the upper side of the fencing frame 2; in the initial state, a layer of protective sheet material covers the bottom adhesive structure of the breathable patch 1. When in use, the protective sheet material at the bottom of the breathable patch 1 can be removed to expose the bottom adhesive structure of the breathable patch 1.

[0019] like Figure 4 and Figure 6 As shown, the mesh structure of the gauze 3 is located in the central area, and the side edge area of ​​the gauze 3 covered by the absorbent cotton 4 does not have a mesh structure, so that the sprayed sterile water can pass through the mesh structure in the central area of ​​the gauze 3 and more effectively cover the wound on the skin; a layer of covering gauze 6 is provided between the bottom of the protective patch 5 and the upper side of the enclosure frame 2.

[0020] When using the breathable patch 1, medical staff remove the protective material from the bottom of the patch and attach the exposed adhesive structure to the patient's skin. The breathable patch 1 has a baffle frame 2 and a gauze 3. The bottom of the gauze 3 is aligned with the wound on the skin. The dressing layer is filled between the baffle frame 2 and the gauze 3. Then, the covering gauze 6 is placed over the baffle frame 2 and the dressing layer. Finally, the protective patch 5 is placed over the breathable patch 1 and the covering gauze 6. This provides a leak-proof, dustproof, and antibacterial cover for the dressing layer between the baffle frame 2 and the gauze 3. The dressing layer continuously treats the wound on the skin through the gauze 3.

[0021] During regular dressing changes, medical staff peel the protective patch 5 from the breathable patch 1 and the covering gauze 6. Through the covering gauze 6, they spray sterile water onto the dressing layer inside the gauze mesh 3. The sterile water seeps through the covering gauze 6, the dressing layer, and the gauze mesh 3 to contact the wound on the patient's skin, making it easier to separate the gauze mesh 3 from the wound. At this time, the absorbent cotton 4 absorbs excess sterile water, preventing leakage onto the breathable patch 1 and reducing the risk of the patch becoming wet and losing its adhesive strength. The medical staff then... (The sentence is incomplete and ends abruptly.) Pinch the two sides of the pull tab 201 with the 6-pinch and slowly peel off the front and back sides of the 2-pinch and the gauze 3 from the wound on the patient's skin. After the medical staff disinfects and cleans the wound on the patient's skin, they then replace the 2-pinch, the gauze 3, the absorbent cotton 4, the dressing layer, the covering gauze 6, and the protective patch 5 on the breathable patch 1 in the same order. This reduces the frequency of removing and replacing the breathable patch 1, thereby reducing complications such as skin barrier damage and contact dermatitis caused by repeated peeling and pasting of the adhesive layer in the same wound area, as well as the patient's pain.

[0022] Example 2, as Figures 1-7 As shown, based on Example 1, the gauze 3 has a dividing ring 301, which divides the space above the gauze 3 into an inner dressing area and an outer dressing area. The inner dressing area, located inside the dividing ring 301 on the gauze 3, is directly aligned with the wound on the skin. The inner dressing area is filled with an antibacterial dressing layer containing silver ions to control infection and is loaded with a dressing layer containing growth factors to promote tissue regeneration in the mid-to-late stages of healing. The outer dressing area, located outside the dividing ring 301 on the gauze 3, is aligned with the area around the wound on the skin. The outer dressing area is filled with a foam dressing layer with strong exudate absorption capacity and is loaded with an alginate dressing layer to absorb moderate to severe exudate. After contact with exudate, it releases calcium ions to help stop bleeding and forms a soft gel after absorption to protect nerve endings and reduce pain. The bottom of the gauze 3... The dressing has several drainage grooves 302. During the process of separating the gauze 3 from the skin wound by spraying sterile water, the sterile water penetrates to the bottom of the gauze 3 and then diffuses evenly to adjacent areas along the drainage grooves 302, improving the flow and coverage of sterile water between the bottom of the gauze 3 and the skin wound. The gauze 3 is woven from medical-grade polyester fiber material, which has high tensile strength, excellent abrasion resistance and disinfection resistance, good biocompatibility, and is non-toxic and non-irritating. It can provide a stable structural support for the dressing system. The size of the mesh and the weaving density can be precisely controlled by the synthetic polymer fiber material, which can reduce the risk of secondary damage caused by the growth of new granulation tissue into the gauze and then tearing it off, while ensuring good permeability and drug release performance, providing an ideal substrate carrier for zoned dressing treatment.

[0023] Example 3, as Figures 1-7 As shown, based on Example 1, the bottom of the gauze 3 is provided with a collection ring groove 303; the collection ring groove 303 of the gauze 3 is located below the absorbent cotton 4; several through holes 304 are opened on the collection ring groove 303 of the gauze 3; a water-blocking ring 7 is provided in the central area of ​​the bottom of the breathable patch 1, and the water-blocking ring 7 is located between the breathable patch 1 and the enclosure frame 2; the breathable patch 1, the enclosure frame 2 and the gauze 3 are in close contact with the skin, and the water-blocking ring 7 is isolated between the breathable patch 1 and the enclosure frame 2. During the process of the nursing staff spraying sterile water between the gauze 3 and the skin wound for separation, the excess sterile water at the bottom of the gauze 3 will spread to the surroundings. When the excess sterile water flows to the bottom of the gauze 3... When the fluid collection ring 303 is in place, sterile water accumulates in the fluid collection ring 303. The sterile water accumulated in the fluid collection ring 303 will pass through the through hole 304 and come into contact with the absorbent cotton 4. The absorbent cotton 4 will absorb the excess sterile water in time. In conjunction with the water-blocking ring 7 that isolates the breathable patch 1 and the enclosure frame 2, the phenomenon of excess sterile water spreading to the surroundings and wetting the breathable patch 1 is effectively reduced. This multi-protection mechanism effectively reduces the situation of the breathable patch 1 becoming wet due to liquid leakage, resulting in adhesion failure, and even common clinical problems such as skin maceration. It significantly improves the safety, cleanliness and patient comfort of the dressing change process, while maintaining the integrity, sealing and adhesion durability of the breathable patch 1.
