Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a wound treatment patch for use in a high-flow-rate humidification therapy device. Background Technology

[0002] In medical wound treatment, the positive effects of high-concentration oxygen on promoting wound healing have been extensively studied and fully validated in clinical practice. By increasing the local tissue oxygen partial pressure, it can effectively inhibit the growth of anaerobic bacteria, improve the cellular metabolic environment, and accelerate angiogenesis. However, although high-flow-rate humidification therapy devices are relatively mature in the field of respiratory support and can output high-flow-rate gas with precise temperature and humidity control, there is currently a lack of dedicated connection devices in clinical practice that can effectively connect such devices to wound treatment scenarios, which greatly limits the practical application of this treatment method.

[0003] In existing technologies, there is no dedicated interface for delivering high-concentration, high-flow-rate humidified gas to wound areas. In limited clinical explorations, temporary, piecemeal connection methods are often used, such as using simple covers as substitutes. However, the covers used to cover or come into contact with the skin in traditional solutions are mostly made of ordinary plastic or metal materials, which are hard and can easily cause mechanical irritation or pressure damage to the skin around the wound after prolonged contact. Moreover, after the airflow enters the wound area, it is difficult to form an effective circulation, resulting in the retention of local metabolic products such as carbon dioxide, creating a moist and closed microenvironment that is conducive to bacterial growth and increases the chance of wound infection. Summary of the Invention

[0004] The main objective of this invention is to provide a wound treatment patch for a high-flow-rate humidification therapy device, which enables the high-flow-rate gas output from the high-flow-rate humidification therapy device to be delivered to the wound site for wound treatment, while avoiding mechanical irritation, pressure damage or pressure sores on the healthy skin around the wound, thus improving comfort and safety.

[0005] To achieve the above objectives, the present invention provides a wound treatment patch for a high-flow-rate humidification therapy device, comprising: A breathable transparent membrane, wherein the breathable transparent membrane has multiple vent holes for allowing gas to pass through; An adhesive layer is disposed along the periphery of the breathable transparent membrane and is configured to adhere to the skin around the wound; An interface base is mounted on one side wall of the adhesive layer, and the interface base has a hollow channel configured to allow gas to pass through. A connecting member, one end of which is connected to the interface base, and the other end of which is used to connect to the interface of the high-flow-rate humidification therapy device.

[0006] Optionally, the inner wall of the interface base is provided with a plurality of annular slots at intervals along its axial direction, and the outer wall of the connecting member is provided with a plurality of annular protrusions at intervals. The plurality of annular protrusions and the plurality of annular slots correspond one-to-one. The connecting member and the interface base are interference-fitted, and the annular protrusions are embedded in the annular slots.

[0007] Optionally, the interface base is made of one of silicone rubber, thermoplastic polyurethane, or polyolefin elastomer.

[0008] Optionally, a temperature-sensing patch is provided on the breathable transparent membrane, which is used to monitor the temperature of the wound area.

[0009] Optionally, the end of the connecting member away from the interface base is provided with a tapered connector, which is used to connect to the interface of the high-flow-rate humidification therapy device.

[0010] Optionally, the breathable transparent membrane is rectangular in shape, with a length of 5cm to 10cm and a width of 3cm to 8cm.

[0011] Optionally, the diameter of the vent hole is 0.1cm to 0.3cm, and the center distance between two adjacent vent holes is 0.5cm to 1.0cm.

[0012] Optionally, the diameter of the hollow channel is 2cm to 4cm.

[0013] Optionally, the width of the adhesive layer is 0.5cm to 1cm.

[0014] Optionally, the breathable transparent membrane is square in shape, and the side length of the breathable transparent membrane is 4cm to 9cm.

[0015] Beneficial effects: The wound treatment patch for a high-flow-rate humidification therapy device proposed in this invention includes a breathable transparent film, an adhesive layer, an interface base, and a connecting member. The breathable transparent film has multiple vent holes to allow gas to pass through. The adhesive layer is disposed along the periphery of the breathable transparent film and is configured to adhere to the skin around the wound. The interface base is mounted on one side wall of the adhesive layer and has a hollow channel configured to allow gas to pass through. One end of the connecting member is connected to the interface base, and the other end of the connecting member is used to connect to the interface of the high-flow-rate humidification therapy device. This design allows the breathable transparent membrane to firmly cover the wound area via an adhesive layer located around its perimeter. The gas chamber formed by the breathable transparent membrane, adhesive layer, and skin wound can hold gas, while multiple vents on the breathable transparent membrane allow gas to escape. This enables the high-flow-rate humidified gas entering through the interface base to fill the gas chamber. Simultaneously, the gas in the gas chamber escapes through the vents, ensuring a continuous flow of high-concentration oxygen to flush the wound surface. The gas escaping from the vents also removes accumulated carbon dioxide from the gas chamber, inhibiting the growth of anaerobic bacteria and accelerating skin wound healing. Furthermore, the adhesive layer is positioned along the perimeter of the breathable transparent membrane and adheres to the healthy skin around the wound, preventing pressure damage to the fragile skin around the wound.

[0024] In medical wound treatment, the positive effects of high-concentration oxygen on promoting wound healing have been extensively studied and fully validated in clinical practice. By increasing the local tissue oxygen partial pressure, it can effectively inhibit the growth of anaerobic bacteria, improve the cellular metabolic environment, and accelerate angiogenesis. However, although high-flow-rate humidification therapy devices are relatively mature in the field of respiratory support and can output high-flow-rate gas with precise temperature and humidity control, there is currently a lack of dedicated connection devices in clinical practice that can effectively connect such devices to wound treatment scenarios, which greatly limits the practical application of this treatment method.

[0025] In existing technologies, there is no dedicated interface for delivering high-concentration, high-flow-rate humidified gas to wound areas. In limited clinical explorations, temporary, piecemeal connection methods are often used, such as using simple covers as substitutes. However, the covers used to cover or come into contact with the skin in traditional solutions are mostly made of ordinary plastic or metal materials, which are hard and can easily cause mechanical irritation or pressure damage to the skin around the wound after prolonged contact. Moreover, after the airflow enters the wound area, it is difficult to form an effective circulation, resulting in the retention of local metabolic products such as carbon dioxide, creating a moist and closed microenvironment that is conducive to bacterial growth and increases the chance of wound infection.

[0026] Based on this, the wound treatment patch proposed in this invention for high-flow-rate humidification therapy devices can deliver the high-flow-rate gas output from the high-flow-rate humidification therapy device to the local wound for wound treatment, and can also avoid mechanical stimulation, pressure damage or pressure sores on the healthy skin around the wound, thus improving the comfort and safety of use.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1 See Figures 1-5 As shown, the wound treatment patch for a high-flow-rate humidification therapy device provided in this embodiment 1 includes a rectangular breathable transparent film 1, an adhesive layer 2, an interface base 3, and a connecting member 4.

[0029] The breathable transparent membrane 1 has multiple ventilation holes 11 extending through its upper and lower surfaces to allow gas to pass through. An adhesive layer 2 is disposed along the perimeter of the breathable transparent membrane 1 and is configured to adhere to the skin surrounding the wound. Specifically, the adhesive layer 2 forms a closed, sealed border at the lower edge of the breathable transparent membrane 1, while the central area of ​​the breathable transparent membrane 1, corresponding to the area above the wound, is not covered with adhesive. The adhesive layer 2 is configured to adhere to the healthy skin surrounding the wound.

[0030] During use, the adhesive layer 2 adheres tightly to the healthy skin surrounding the wound, working together with the breathable transparent membrane 1 to confine the wound area within a gaseous environment, preventing unintended leakage of high-velocity humidified gas from the edges. The adhesive layer 2 is preferably made of medical-grade acrylic pressure-sensitive adhesive or silicone gel. Silicone gel is suitable for patients with fragile or sensitive skin, such as the elderly, infants, or those who are bedridden for extended periods. Silicone gel not only has a gentle adhesiveness and is easily removable without causing pain, but it also reduces damage to the stratum corneum of the skin.

[0031] By confining the adhesive layer 2 to the periphery of the breathable transparent membrane 1, the risk of the adhesive layer 2 adhering to the fragile skin of the wound area can be reduced. Wounds are often accompanied by tissue loss, new granulation tissue, or epithelial cell creep, which are extremely fragile. If the adhesive layer 2 comes into contact with these tissues, it can easily cause secondary damage during removal, thus delaying healing.

[0032] The above structural design allows the adhesive layer 2 to be placed on the healthy skin around the wound, while the middle area of ​​the breathable transparent membrane 1 is suspended over the wound, maintaining a certain physical gap with the wound surface.

[0033] In this embodiment 1, the upper surface of the breathable transparent membrane 1, the inner edge of the adhesive layer 2, and the surface of human skin together define a gas chamber.

[0034] The interface base 3 is installed on one side wall of the adhesive layer 2. The interface base 3 has a hollow channel 31 that runs through both ends of the interface base 3. One end of the hollow channel 31 is used to dock with the connecting member 4, and the other end is connected to the gas chamber below the breathable transparent membrane 1. The hollow channel 31 is configured as a channel for gas to enter the gas chamber.

[0035] Specifically, one end of the interface base 3 has a disc-shaped base, which is used to increase the contact area with the adhesive layer 2, thereby improving the connection strength between the two and ensuring that the interface base 3 is not easy to fall off the adhesive layer 2 when subjected to pipeline tension.

[0036] One end of the connecting member 4 is connected to the interface base 3, and the other end of the connecting member 4 is used to connect to the interface of the high-flow-rate humidification therapy device. Through the connecting member 4, the wound treatment patch can establish a stable gas transmission path with the high-flow-rate humidification therapy device, so that the high-flow-rate humidification gas generated by the high-flow-rate humidification therapy device can be continuously and controllably delivered to the wound area.

[0037] In this embodiment 1, the breathable and transparent membrane 1 is made of a medical-grade polymer material with high transparency, such as polyurethane or polyester film. During the treatment process, the operator can directly observe the color change of the wound, the nature of the exudate and the progress of healing without removing the wound treatment patch, thereby greatly reducing the risk of interfering with the wound healing process due to frequent opening of the wound treatment patch.

[0038] In a preferred embodiment of this example 1, a plurality of vent holes 11 are disposed on both sides of the breathable transparent membrane 1 in the width direction. Specifically, based on the distribution position of the plurality of vent holes 11 on the breathable transparent membrane 1, they can be divided into two groups: one group of vent holes 11 is located in the right end region of the breathable transparent membrane 1, and the other group of vent holes 11 is located in the left end region of the breathable transparent membrane 1. Here, "left end" and "right end" refer to the width W1 direction of the breathable transparent membrane, meaning that the two groups of vent holes 11 are respectively distributed on the two sides of the breathable transparent membrane 1 or in the region near the edge, and the group of vent holes 11 located in the right end region of the breathable transparent membrane 1 and the other group of vent holes 11 located in the left end region of the breathable transparent membrane 1 are symmetrically distributed.

[0039] The interface base 3 is installed on one side wall of the adhesive layer 2. Specifically, the interface base 3 is connected to the middle area of ​​the short side of the adhesive layer 2. The high-concentration humidified gas delivered by the high-flow-rate humidification therapy device is introduced into the gas chamber through the interface base 3. Since multiple vents 11 are distributed on both sides of the width direction of the breathable transparent membrane 1, that is, multiple vents 11 are distributed along the long edge of the breathable transparent membrane 1, the high-concentration humidified gas entering the gas chamber tends to diffuse from the inlet position to both sides of the gas chamber, and finally exits through the vents 11 located around the breathable transparent membrane 1.

[0040] In practical use, the high-concentration humidified gas delivered by the high-flow-rate humidification therapy device is introduced into the gas chamber formed by the wound treatment patch and human skin through the interface base 3. The high-concentration humidified gas refers to medical-grade oxygen or medical-grade air that has undergone heating and humidification treatment, achieving a relative humidity of over 95% and a temperature controlled at around 37 degrees Celsius, close to human body temperature. After entering the gas chamber, the high-concentration humidified gas initially enters from the middle of the short side of the gas chamber, as the gas chamber is defined by the upper surface of the breathable transparent membrane 1, the inner edge of the adhesive layer 2, and the surface of the human skin. The interface base 3 is connected to the middle of the short side of the adhesive layer 2. Driven by internal pressure, the high-concentration humidified gas moves from the middle of the short side of the gas chamber towards both sides, continuously moving towards and exiting the edges of the breathable transparent membrane 1. This maintains a high-humidity, high-oxygen-concentration gas environment above the wound, effectively promoting wound healing.

[0041] In another preferred embodiment of this embodiment 1, a plurality of ventilation holes 11 are provided on the breathable transparent membrane 1. Unlike the aforementioned distribution of ventilation holes 11 along the long edge of the breathable transparent membrane 1, when the wound shape is relatively regular, approximately circular or elliptical, the plurality of ventilation holes 11 are preferably distributed in a matrix manner.

[0042] Specifically, the matrix distribution involves multiple vents 11 arranged in rows and columns on the breathable transparent membrane 1. In the row direction, the center-to-center distance between adjacent vents 11 remains equal; in the column direction, the center-to-center distance between adjacent vents 11 also remains equal. Through this arrangement with equal row and column spacing, the multiple vents 11 together form a uniform gas discharge network.

[0043] When the high-flow-rate humidifying gas is injected into the gas chamber through the interface base 3, it diffuses from the inlet to the surrounding area under the pressure difference. Since multiple vents 11 are evenly distributed on the breathable transparent membrane 1, their resistance to airflow also exhibits a uniform distribution characteristic. During the diffusion of the gas to the surrounding area, it can be distributed to the area near each vent 11, providing a relatively stable microenvironment for wound healing.

[0044] Secondly, the gas discharged from the ventilation hole 11 can remove carbon dioxide, water vapor and a small amount of odorous gas produced by wound metabolism, thereby creating a microenvironment with low carbon dioxide and high oxygen concentration in the wound area. This can effectively inhibit the growth and reproduction of anaerobic bacteria, provide favorable conditions for wound healing, and thus accelerate the wound healing process.

[0045] See Figures 4-5 As shown, the inner wall of the interface base 3 is provided with multiple annular slots 32 at intervals along its axial direction, and the outer wall of the connecting member 4 is provided with multiple annular protrusions 41 at intervals. The multiple annular protrusions 41 and the multiple annular slots 32 correspond one-to-one. The connecting member 4 and the interface base 3 are interference-fitted, and the annular protrusions 41 are embedded in the annular slots 32.

[0046] In this embodiment 1, the connecting member 4 and the interface base 3 are connected by an interference fit. Specifically, the outer diameter of the connecting member 4 in its free state is slightly larger than the diameter of the hollow channel 31 inside the interface base 3. When the connecting member 4 is inserted into the interface base 3, the interface base 3 undergoes elastic deformation. After being inserted into place, the annular protrusion 41 is embedded in the annular groove 32. Through the nesting and cooperation of multiple annular protrusions 41 and multiple annular grooves 32 arranged at intervals, multiple annular sealing lines are constructed on the connection path between the connecting member 4 and the interface base 3, which can reduce the risk of gas leakage and thus improve the airtightness of the connection between the connecting member 4 and the interface base 3.

[0047] In this embodiment 1, the interface base 3 is made of one of silicone rubber, thermoplastic polyurethane, and polyolefin elastomer. A temperature sensing patch is provided on the breathable transparent membrane 1, which is used to monitor the temperature of the wound area.

[0048] Specifically, the installation position of the temperature-sensing patch can be set according to monitoring needs. In a preferred embodiment of this 1, the temperature-sensing patch is attached to the surface of the breathable transparent membrane 1 facing the wound, i.e., the inner surface of the breathable transparent membrane 1, so that the temperature-sensing patch is close to the wound but does not directly contact the wound, in order to sense the temperature of a local area of ​​the wound. In another preferred embodiment of this 1, the temperature-sensing patch is embedded inside the membrane body of the breathable transparent membrane 1, and indirectly senses the temperature around the wound through the heat conduction of the breathable transparent membrane 1. It should be noted that, regardless of the installation method, the placement of the temperature-sensing patch should avoid the vent holes 11 on the breathable transparent membrane 1 to prevent affecting the normal flow of gas.

[0049] In this embodiment 1, the temperature sensing patch itself can be implemented using various technical approaches. For example, the temperature sensing patch preferably uses a flexible thin-film thermocouple or a flexible thermistor as the temperature sensing element, which can bend and deform along with the breathable transparent membrane 1 to adapt to the curved contours of the human body surface. Secondly, the overall thickness is small, typically between tens and hundreds of micrometers, thereby reducing interference with the local gas flow field. The temperature sensing patch is connected to external monitoring equipment via flexible conductive wires. The flexible conductive wires can be led out along the edge of the breathable transparent membrane 1, and the lead-out end of the conductive wire has an electrical connector for connection to an external monitor.

[0050] See Figure 5 As shown, a tapered connector 42 is provided at the end of the connecting member 4 away from the interface base 3. The tapered connector 42 is used to connect to the interface of the high-flow-rate humidification therapy device. Specifically, the tapered connector 42 has an overall cone shape. The tapered connector 42 gradually tapers from its connection point with the connecting member 4 towards its free end, forming a tapered structure with a gradually decreasing outer diameter. The tapered connector 42 and the connecting member 4 are made of the same material through an integral molding process. It can be made of polypropylene or polyethylene.

[0051] In this embodiment 1, the breathable transparent membrane 1 is rectangular in shape. This rectangular shape is suitable for covering wounds that are relatively long or irregular in shape, such as surgical incisions, linear injuries, or wounds located on limbs. Clinically common small to medium-sized wounds typically have a maximum linear dimension between several centimeters and ten centimeters. In this embodiment 1, the length L1 of the rectangular breathable transparent membrane is 5cm to 10cm, and the width W1 is 3cm to 8cm. This ensures coverage of most small to medium-sized wounds while avoiding material waste and patient discomfort caused by excessively large sizes.

[0052] In this embodiment 1, the diameter of the vent 11 is 0.1cm to 0.3cm, and the center distance between two adjacent vents 11 is 0.5cm to 1.0cm. In a preferred embodiment of this embodiment 1, the diameter of the vent 11 is 0.1cm. This design not only enhances the throttling effect on airflow, helping to establish a relatively stable gas environment within the gas chamber and ensuring that the gas is evenly distributed throughout the wound area, but also effectively prevents large external particulate contaminants from entering the gas chamber through the openings, reducing the risk of exogenous infection.

[0053] In some treatment scenarios that require a higher gas flow rate, the diameter of the vent 11 is 0.3 cm, which can reduce the resistance to gas discharge and allow the gas in the gas chamber to be discharged smoothly.

[0054] In this embodiment 1, the diameter of the hollow channel 31 is 2cm to 4cm, and the width W2 of the adhesive layer is 0.5cm to 1cm.

[0055] To further explain, this embodiment 1 also provides the process of using the wound treatment patch, as follows: Before clinical use, first insert the end of the connecting member 4 with the annular protrusion 41 into the interface base 3 until all the annular protrusions 41 are embedded in the corresponding annular grooves 32. Then insert the end of the connecting member 4 with the conical connector 42 into the output interface of the high-flow-rate humidification therapy device and push it in to an appropriate depth to ensure that the two fit together tightly.

[0056] After cleaning the wound, the operator removes the release film from the adhesive layer 2, aligns the center of the wound dressing with the wound, and gently places it on the wound area, ensuring the center of the breathable transparent membrane 1 is directly facing the wound. Then, the operator presses down on the surrounding edges of the adhesive layer 2 to ensure it adheres smoothly to the healthy skin around the wound, forming a gas chamber with the breathable transparent membrane 1 at the top, the skin wound at the bottom, and the adhesive layer 2 as the sidewalls. At this point, a temperature-sensing patch placed on the breathable transparent membrane 1 is positioned facing the wound area to monitor the temperature around the wound.

[0057] Subsequently, the high-flow-rate humidification therapy device is activated, and the operator sets the treatment parameters according to the doctor's orders, including gas flow rate, temperature, and humidity. The high-flow-rate humidification therapy device heats and humidifies the gas to achieve the set treatment state. The treated high-flow-rate humidified gas is injected into the gas chamber at the set flow rate and pressure through the hollow channel 31 of the connecting component 4 and the interface base 3. After entering the gas chamber, it diffuses outward under pressure and flows over the wound surface. During the flow, the gas carries away carbon dioxide, water vapor, and volatile odor substances produced by wound metabolism, while providing the wound tissue with a high concentration of oxygen and suitable humidity. Finally, it exits the gas chamber through the vents 11 on the breathable transparent membrane 1 and enters the external environment.

[0058] Example 2 Unlike Example 1, the wound treatment patch for a high-flow-rate humidification therapy device provided in Example 2 is described below. Figure 6 As shown, the breathable transparent membrane 1 is square in shape, and the side length L2 of the breathable transparent membrane is 4cm~9cm.

[0059] Specifically, the breathable transparent membrane 1 is square in shape and is suitable for covering wounds with relatively regular shapes, such as circular or near-circular wounds.

[0060] The square-shaped breathable transparent membrane has a side length L2 of 4cm to 9cm. This range of side lengths is based on the statistical distribution of common clinical wound sizes. A 4cm side breathable transparent membrane 1 has a coverage area of ​​approximately 16 square centimeters, which is sufficient to cover most circular wounds with a diameter of 2 to 3 centimeters. A 9cm side breathable transparent membrane 1 has a coverage area of ​​81 square centimeters, which can cover larger wounds with a diameter of approximately 7 to 8 centimeters. By providing breathable transparent membranes 1 with different side lengths, operators can choose according to the actual size of the wound.

[0061] The other structures are the same as in Example 1, and will not be described again here.

[0062] In summary, the wound treatment patch for a high-flow-rate humidification therapy device proposed in this invention includes a breathable transparent film 1, an adhesive layer 2, an interface base 3, and a connecting member 4. The breathable transparent film 1 has multiple vent holes 11 for allowing gas to pass through. The adhesive layer 2 is disposed along the periphery of the breathable transparent film 1 and is configured to adhere to the skin around the wound. The interface base 3 is mounted on one side wall of the adhesive layer 2 and has a hollow channel 31 configured to allow gas to pass through. One end of the connecting member 4 is connected to the interface base 3, and the other end of the connecting member 4 is used to connect to the interface of the high-flow-rate humidification therapy device. In this design, the breathable transparent membrane 1 is firmly covered above the wound area by the adhesive layer 2 located at its four edges. The gas chamber formed by the breathable transparent membrane 1, the adhesive layer 2, and the skin wound can contain gas. Multiple vents 11 on the breathable transparent membrane 1 allow gas to be discharged outward, so that the high-flow-rate humidified gas entering through the interface base 3 can fill the gas chamber. At the same time, the gas in the gas chamber is discharged outward through the vents 11, thus ensuring that a high concentration of oxygen can continuously enter the gas chamber to flush the wound surface. At the same time, the gas discharged from the vents 11 can also remove the carbon dioxide accumulated in the gas chamber, inhibit the growth of anaerobic bacteria, and accelerate the healing of the skin wound. Meanwhile, the adhesive layer 2 is set along the four edges of the breathable transparent membrane 1 and fits against the healthy skin around the wound, avoiding pressure damage to the fragile skin around the wound.
