Description

Technical Field

[0001] This invention relates to the field of medical wound care equipment technology, and in particular to a wound oxygen therapy drying device. Background Technology

[0002] In clinical nursing, critically ill, elderly, and long-term bedridden patients have a particularly high probability of skin damage. This is mainly because prolonged bed rest reduces the skin's ability to protect against mechanical forces such as friction, leading to local skin tissue ischemia and hypoxia. At the same time, factors such as long-term irritation and moisture from urine and feces can damage the stratum corneum, resulting in discomfort symptoms such as skin redness and eczema. In severe cases, pressure injuries may occur. If not treated promptly and specifically, the wound may be difficult to heal or even worsen. In such cases, wound oxygen therapy and drying devices are needed.

[0003] In practical use, similar drying devices still have many shortcomings, such as: traditional dressings cannot balance the contradiction between oxygen supply and drug penetration, and traditional wound oxygen therapy drying devices are not suitable for primary healthcare scenarios due to their complex oxygen supply equipment. Therefore, it is necessary to design a wound oxygen therapy drying device. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a wound oxygen therapy drying device.

[0005] The present invention is achieved by the following technical solution: a wound oxygen therapy drying device, comprising an adhesive layer, a first foam dressing layer, a gas pipe layer, a second foam dressing layer and a breathable non-woven fabric layer, wherein the gas pipe layer is snapped onto one side of the adhesive layer through the first foam dressing layer, the second foam dressing layer is snapped onto the outer surface of the gas pipe layer, and the breathable non-woven fabric layer is adhered to the outer surface of the second foam dressing layer.

[0006] As a further improvement to the above solution, a sterile gauze layer is adhered to the outer surface of the adhesive layer, and a gas pipe layer is snapped onto one side of the sterile gauze layer through a first foam dressing layer.

[0007] The above technical solution combines wound protection and drug delivery functions through the skin-friendly material and antibacterial properties of the sterile gauze layer, reducing friction damage while supporting local drug delivery, thus improving patient comfort and treatment effectiveness.

[0008] As a further improvement to the above solution, an embedding groove is provided inside the first foam dressing layer, and a gas pipe layer is snapped into the inside of the embedding groove.

[0009] Through the above technical solution, the precise fit design of the embedded groove ensures stable positioning of the gas pipeline layer, avoids the risk of pipeline twisting or leakage caused by traditional binding fixation, and improves oxygen delivery efficiency and safety.

[0010] As a further improvement to the above solution, a gas pipeline body is fixedly connected to the bottom of the gas pipeline layer, and a gas pipe device connector is fixedly connected to the outer surface of the gas pipeline body.

[0011] Through the above technical solution, the integrated structure of the gas pipeline body and the gas pipe device connector enables quick assembly and disassembly, supporting plug-and-play use of oxygen source equipment of different specifications.

[0012] As a further improvement to the above solution, one side of the tracheal device connector is fitted with a structure connecting both ends, and a connecting pipe is fixedly connected inside the structure connecting both ends.

[0013] Through the above technical solutions, the standardized interface design enables the connecting tube to be adapted to various medical device catheter systems, enhancing the versatility and compatibility of the device and meeting the needs of multidisciplinary joint treatment scenarios.

[0014] As a further improvement to the above solution, the breathable nonwoven fabric layer has air pores inside, and the air pores are set as small circular holes.

[0015] Through the above technical solution, the evenly distributed circular vents ensure wound ventilation while preventing liquid penetration, maintaining a dynamic balance between the moist healing environment and the need for dry treatment, and promoting tissue regeneration.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention utilizes a multi-layered composite structure consisting of an adhesive layer, a sterile gauze layer, a first foam dressing layer, a gas conduit layer, a second foam dressing layer, and a breathable non-woven fabric layer. This structure facilitates the synergistic effect of oxygen gradient penetration and sustained drug release, thereby achieving precise control of the wound microenvironment. The design employs embedded grooves to precisely anchor the gas conduit system, combined with radial airflow distribution formed by circular ventilation holes. This allows for the continuous application of high-concentration oxygen to the wound, forming a physical barrier to inhibit anaerobic bacterial colonization. Simultaneously, the drug components carried by the sterile gauze layer are evenly diffused to the lesion area with the airflow, achieving the dual effects of anti-infection treatment and tissue regeneration. The biomechanical cushioning properties of the double-layered foam dressing effectively prevent pressure-induced damage, making it particularly suitable for the skin protection needs of long-term bedridden patients.

[0018] This invention operates through a standardized interface module consisting of a tracheal device connector, connecting pipe, and connecting ends, enabling compatibility with multiple oxygen sources and facilitating flexible deployment in primary healthcare settings. This design adopts internationally recognized medical device connection standards, supporting rapid connection to various gas sources such as portable oxygen concentrators and central oxygen supply systems. The flexible corrugated structure of the gas pipeline adapts to the anatomical curves of patients in different positions, ensuring stable oxygen supply in supine, lateral, and other postures. The plug-and-play nature of the modular components significantly reduces the operational difficulty for nursing staff, perfectly meeting the special needs of elderly and critically ill patients for convenient and safe monitoring.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-6This embodiment of a wound oxygen therapy drying device includes an adhesive layer 1, a first foam dressing layer 3, a gas pipe layer 5, a second foam dressing layer 10, and a breathable non-woven fabric layer 11. The gas pipe layer 5 is snapped onto one side of the adhesive layer 1 through the first foam dressing layer 3. The second foam dressing layer 10 is snapped onto the outer surface of the gas pipe layer 5. The breathable non-woven fabric layer 11 is adhered to the outer surface of the second foam dressing layer 10.

[0030] A sterile gauze layer 2 is bonded to the outer surface of the adhesive layer 1, and a gas pipe layer 5 is attached to one side of the sterile gauze layer 2 through a first foam dressing layer 3.

[0031] The first foam dressing layer 3 has an embedded groove 4 inside, and a gas pipe layer 5 is snapped into the embedded groove 4.

[0032] A gas pipeline body 6 is fixedly connected to the bottom of the gas pipeline layer 5, and a gas pipe device connector 7 is fixedly connected to the outer surface of the gas pipeline body 6.

[0033] One side of the tracheal device connector 7 is snapped with a connecting end structure 8, and a connecting pipe 9 is fixedly connected inside the connecting end structure 8.

[0034] When the oxygen source is connected to the tracheal device connector 7 through the connecting pipe 9, the gas enters the gas pipe layer 5 along the gas pipe body 6. The air outlets distributed in this layer form a continuous airflow field around the wound. This airflow passes through the sterile gauze layer 2 and is accurately delivered to the target area.

[0035] After the gas is acted upon, it passes through the second foam dressing layer 10 and then exits through the circular air vents 12 on the surface of the breathable nonwoven fabric layer 11.

[0036] The breathable nonwoven fabric layer 11 has air holes 12 inside, and the air holes 12 are small circular holes.

[0037] The implementation principle of the wound oxygen therapy drying device in this embodiment is as follows: The adhesive layer 1 achieves reliable fixation to the patient's skin, ensuring stable adhesion of each layer. The sterile gauze layer 2 covering it serves as the direct contact surface, providing soft, skin-friendly protection and supporting medication application. When the oxygen source is connected to the endotracheal device connector 7 via the connecting pipe 9, the gas enters the gas pipe layer 5 along the gas pipe body 6. The air outlets distributed in this layer form a continuous airflow field surrounding the wound. This airflow passes through the sterile gauze layer 2 and is precisely delivered to the target area. After the airflow acts, it passes through the second foam dressing layer 10 and then exits through the circular ventilation holes 12 on the surface of the breathable non-woven fabric layer 11. The embedded groove 4 inside the first foam dressing layer 3 securely engages the gas pipe system, and the buffering effect of the upper and lower foam layers reduces local pressure. The entire multi-layer composite structure achieves a synergistic effect of oxygen supply, drug penetration, moisture removal, and wound protection through its layered design, thereby inhibiting anaerobic bacterial growth, improving tissue hypoxia, and accelerating healing.

[0038] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
