Description

Technical Field

[0001] This application relates to the technical field of wound healing, and particularly to a device for promoting wound repair. Background Art

[0002] In the prior art, the healing of some wounds is relatively slow. In order to promote the healing of wounds, negative pressure is applied to the wounds to improve the healing speed. Among them, the healing of diabetic wounds is particularly difficult, which is a major challenge in clinical practice. Therefore, it is crucial to develop effective strategies for promoting the healing of diabetic wounds. VSD is a negative pressure wound treatment technology and is a widely used wound treatment method in clinical practice. It has many advantages in aspects such as wound care, protecting the wound, and accelerating wound healing by reducing wound secretions and creating a moist environment. It can reduce edema, enhance local blood flow, stimulate angiogenesis and granulation tissue formation, accelerate the growth of epithelial cells, promote wound epithelialization, and thus accelerate wound healing. However, there are also certain limitations in the clinical application of VSD technology, especially in terms of the compatibility of drug treatment. Since the VSD system promotes wound healing through a closed negative pressure environment, although its sealing property helps prevent external contamination, it also restricts the synchronous application of drugs. When using the VSD technology, it is difficult to directly apply drugs to the wound through traditional dressings or local drug administration methods, which makes it impossible to effectively intervene with drugs while performing negative pressure drainage for some wounds that require local drug treatment (such as infected wounds or special pathogen infections). This technical limitation may affect the comprehensive treatment effect of the wound, especially when dealing with complex wounds or multi-drug resistant bacteria infections, and a trade-off and choice need to be made between VSD treatment and local drug administration. Therefore, a device for promoting wound repair is needed, which can apply negative pressure to the wound and also facilitate drug intervention. Summary of the Invention

[0023] In the prior art, it is extremely difficult to heal some wounds. For example, diabetic foot ulcers, etc. Without intervention, these wounds are very difficult to heal on their own or the healing speed is relatively slow. And negative pressure stimulation of wounds is a widely used wound treatment method in clinical practice. It has many advantages in aspects such as wound care, wound protection, and accelerating wound healing by reducing wound secretions and creating a moist environment. It can reduce edema, enhance local blood flow, stimulate angiogenesis and granulation tissue formation, accelerate the growth of epithelial cells, promote wound epithelialization, and thus accelerate wound healing. Promote wound healing through a closed negative pressure environment, and its sealing property also helps to prevent external contamination.

[0024] Slow wound healing has many hazards. First, if the wound does not heal for a long time, bacteria are likely to breed at the wound site, leading to the spread of infection. The infection may further spread to other parts, causing sepsis or failure of other organ functions, and may be life-threatening in severe cases. Second, slow wound healing may lead to complications such as necrotic tissue and edema on the wound surface. These factors will hinder the growth of new granulation tissue and the repair process, resulting in delayed or non-healing of the wound, further increasing the risk of infection and prolonging the recovery time. Moreover, a wound that does not heal for a long time may cause nerve damage or inflammation, resulting in chronic pain. Severe pain will affect the patient's daily activity ability and reduce the quality of life. In addition, long-term discomfort may also cause muscle atrophy or joint stiffness, leading to limited movement and dysfunction. At the same time, long-term non-healing of the wound will weaken the body's defense against pathogens, resulting in a decline in the body's immune function. This will make the patient more susceptible to secondary infections and require additional antibiotic treatment to control the progression of the disease. Also, the long-term existence of the wound may lead to nutrient loss, affecting the overall health of the patient. At the same time, due to slow wound healing, the patient needs to receive treatment and care for a longer time, thus increasing medical costs and financial burdens. Additionally, for some patients, such as diabetic patients, slow wound healing may increase the risk of specific complications. For example, if a diabetic patient's wound does not heal for a long time, it may lead to serious consequences such as local wound infection and protein synthesis disorders. Therefore, it is necessary to promote the rapid healing of the wound.

[0025] The long-term accumulation of tissue fluid secreted by the wound and the medicinal liquid will affect the healing of the wound. Tissue fluid is a transparent liquid naturally produced during the wound healing process. It helps clean the wound and promote healing. However, when there is too much tissue fluid and it accumulates on the wound, it may hinder the wound healing process. This is because the accumulated tissue fluid may form a moist environment that is conducive to the growth and reproduction of bacteria, thus increasing the risk of wound infection. After infection, the wound may become red, swollen, and more painful, and even fester, resulting in an extended healing time. Therefore, through appropriate treatment and care, this impact can be reduced and wound healing can be promoted.

[0026] The accumulation of wound tissue fluid may have a certain impact on the absorption of drugs by the wound. This accumulation may affect the local microenvironment of the wound, including humidity, pH value, etc. These factors may affect the solubility and stability of drugs, thus affecting drug absorption. In addition, the accumulation of wound tissue fluid may also increase the local pressure of the wound, making it difficult for drugs to penetrate into the deep tissue. If the wound tissue fluid contains a large number of inflammatory cells and inflammatory mediators, these components may also interact with the drugs, further affecting drug absorption and efficacy. Therefore, by taking appropriate measures, this impact can be minimized to promote wound healing.

[0027] Refer to Figure 1, Figure 3 , Figure 6 and Figure 7 , an apparatus for promoting wound repair according to an embodiment of the first aspect of the present invention is used to promote wound healing. The apparatus for promoting wound repair includes: an application main body 1, a water sac groove 2, a negative pressure device 3, and a medicine delivery device 4. The application main body 1 is made of a first material, which is a material with pores for absorbing liquid. A sticking surface 11 is provided on the application main body 1 for sticking to the skin surface. The water sac groove 2 is formed on the sticking surface 11, and the wound is exposed in the water sac groove 2. The negative pressure device 3 includes a negative pressure pipeline 31 and a negative pressure pump. The first end of the negative pressure pipeline 31 is connected to the negative pressure pump, and the second end of the negative pressure pipeline 31 is connected to the application main body 1 to form a negative pressure in the water sac groove 2. The medicine delivery device 4 includes a medicine delivery pipeline 41 and a medicine delivery pump. The first end of the medicine delivery pipeline 41 is connected to the medicine delivery pump, and the second end of the medicine delivery pipeline 41 communicates with the water sac groove 2. When using the apparatus for promoting wound repair, the application main body 1 is applied to the skin, and at the same time, the water sac groove 2 on the application main body 1 is aligned with the wound. The water sac groove 2 can be cut into a shape adapted to the shape of the wound. The second end of the negative pressure pipeline 31 is buried inside the application main body 1. At this time, the negative pressure pump can extract air through the negative pressure pipeline 31 and the pores inside the application main body 1 to form a negative pressure in the water sac groove 2. When too much tissue fluid is secreted from the wound, the tissue fluid contacting the edge of the water sac groove 2 will be absorbed by the pores on the application main body 1, and at the same time, the tissue fluid will be sucked out through the negative pressure device 3. When the negative pressure device 3 forms a negative pressure in the water sac groove 2, a certain amount of clean air will enter the water sac groove 2 through the pores, so that the air in the water sac groove 2 can circulate, thereby promoting wound healing. When it is necessary to administer medicine to the wound, the negative pressure device 3 is turned off to restore the air pressure in the water sac groove 2 to normal. Then, the medicine can be delivered into the water sac groove 2 through the medicine delivery device 4 and act on the wound. After the medicine administration is completed and after a certain period of time for the wound to absorb the medicine, the negative pressure device 3 is turned on again to make the wound continue to be in a negative pressure environment. At the same time, the negative pressure device 3 can also wash the medicine waste liquid out of the water sac groove 2 through the negative pressure pipeline 31. In addition, it should be noted that there is a difference between the negative pressure pipeline 31 and the medicine delivery pipeline 41. The second end of the medicine delivery pipeline 41 needs to be directly communicated with the water sac groove 2, that is, the second end of the medicine delivery pipeline 41 is exposed in the water sac groove 2, so that the liquid medicine can be directly delivered into the water sac groove 2. The second end of the negative pressure pipeline 31 needs to be buried inside the application main body 1. The gas passing through the negative pressure pipeline 31 needs to first pass through the pores in the application main body 1, so that not only a negative pressure appears in the water sac groove 2, but also a negative pressure is formed on the skin surface where the application main body 1 is applied through the action of the pores, thereby promoting wound healing.

[0028] The promoting effect of drugs on wound healing is multi-faceted, accelerating the wound repair process through different mechanisms. Specific disinfectants such as 75% ethanol disinfectant solution, hydrogen peroxide solution, and povidone iodine solution are used for the initial cleaning and disinfection of wounds, reducing the risk of infection and creating a sterile environment for wound healing. Antibiotic drugs such as cefixime tablets, cefradine capsules, and amoxicillin tablets, when taken orally or by intravenous injection, help prevent or control infection. Infection is one of the main obstacles to wound healing, and the use of antibiotics can effectively reduce the number of bacteria and promote wound healing. Analgesics such as paracetamol tablets, ibuprofen tablets, and enteric-coated aspirin tablets can relieve the pain and inflammatory response of wounds, reduce activity restrictions caused by pain, and are beneficial for wound care and healing. Topical ointments such as erythromycin ointment, sodium fusidate ointment, tretinoin cream, and mupirocin ointment can be directly applied to the wound surface, having antibacterial, anti-inflammatory, detumescent, and antipruritic effects, helping to reduce the risk of infection and accelerate wound healing. Growth factor drugs such as recombinant human epidermal growth factor gel can promote the synthesis of DNA, RNA, and hydroxyproline during the repair process of skin wound tissue, accelerate the formation of granulation tissue on the wound surface and the proliferation of epithelial cells, thus promoting rapid wound healing. Drugs such as Yunnan Baiyao with the effects of promoting blood circulation to remove blood stasis, stopping bleeding, activating blood circulation to relieve pain, and detoxifying and detumescing can quickly stop bleeding, improve the local blood circulation of the wound, provide sufficient nutrients and oxygen for wound healing, and at the same time resist wound infection and reduce the risk of infection. Drugs promoting blood circulation to remove blood stasis such as notoginseng tablets, Shujin Huoxue tablets, and Huoxue Zhitong capsules can promote blood circulation, improve the microcirculation of the wound, and accelerate the healing process. Steroid drugs such as hydrocortisone ointment and dexamethasone can inhibit excessive inflammatory reactions, but long-term use requires caution. Substances such as hyaluronic acid and collagen are commonly used for moisturization and promoting cell migration, helping to maintain the moisture of the wound environment, providing structural support, thus promoting the generation of new tissues and increasing the healing speed.

[0029] According to some embodiments of the present invention, an outer surface 12 is provided on the application main body 1. The outer surface 12 is arranged opposite to the adhesive surface 11, and a sealing film 5 is applied on the outer surface 12 to block the pores on the outer surface 12. By providing the sealing film 5 to block the pores on the outer surface 12, air can be prevented from entering the negative pressure pipeline 31 through the pores on the outer surface 12, or the amount of air entering through the pores on the outer surface 12 can be reduced, so that a greater negative pressure can be obtained in the water sac groove 2 and on the adhesive surface 11, and at the same time, the magnitude of the negative pressure can be better controlled.

[0030] According to some embodiments of the present invention, referring to Figure 2 and Figure 3, the water sac groove 2 penetrates through the application main body 1 to communicate the outer side surface 12 and the sticking surface 11. The sealing film 5 is made of a transparent material, and the sealing film 5 covers one end of the water sac groove 2 on the outer side surface 12. After the water sac groove 2 penetrates through the main body, covering one end of the water sac groove 2 away from the wound through the sealing film 5 can ensure the negative pressure formed in the water sac groove 2. At the same time, setting the sealing film 5 to be transparent can more conveniently observe the healing state of the wound.

[0031] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 , a movable liquid guide member 6 is arranged in the water sac groove 2. The movable liquid guide member 6 abuts against the side surface of the water sac groove 2. The movable liquid guide member 6 is fixedly connected to the sealing film 5. The thickness of the movable liquid guide member 6 is less than the thickness of the application main body 1. The movable liquid guide member 6 is made of a first material. In order to better drain the tissue fluid secreted by the wound in the water sac groove 2, the movable liquid guide member 6 is provided to absorb the tissue fluid. At the same time, the movable liquid guide member 6 is made to abut against the application main body 1 so that the application main body 1 can better absorb the tissue fluid. At the same time, in order to prevent the movable liquid guide member 6 from absorbing the medicine liquid when administering medicine to the wound, the movable liquid guide member 6 is fixedly arranged on the sealing film 5, so that the movable liquid guide member 6 can move in the water sac groove 2 to be far away from or close to the wound. When a negative pressure is applied to the water sac groove 2, the movable liquid guide member 6 will approach the wound under the action of air pressure, so as to better adsorb the tissue fluid. It should be noted that when the movable liquid guide member 6 approaches the wound, it does not need to abut against the wound. The distance between the movable liquid guide member 6 and the wound when the movable liquid guide member 6 approaches the wound can be adjusted by adjusting the thickness of the movable liquid guide member 6 and the tightness of the sealing film 5. When administering medicine to the water sac groove 2, a certain positive pressure will be generated in the water sac groove 2, and at this time the movable liquid guide member 6 will move away from the wound, thus preventing the movable liquid guide member 6 from absorbing the medicine liquid and avoiding the waste of the medicine liquid. The movable liquid guide member 6 can be set in a grid shape, which can not only fully absorb the tissue fluid on the wound, but also avoid blocking the line of sight for observing the wound.

[0032] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , the edges of the sealing film 5 all extend outside the application main body 1, and the edges of the sealing film 5 are attached to the skin surface. Further reduce the pores on the application main body 1 that can communicate with air, thereby increasing the resistance of air entering the water sac groove 2 when a negative pressure is formed in the water sac groove 2, so as to more conveniently form a negative pressure in the water sac groove 2 and control the magnitude of the negative pressure in the water sac groove 2.

[0033] According to some embodiments of the present invention, the first material is medical foam, and the medical foam includes polyvinyl alcohol or polyurethane. The first material naturally forms a relatively large number of interconnected pores inside, thereby having good air permeability and liquid absorption capacity.

[0034] According to some embodiments of the present invention, referring to Figure 6 , a plurality of negative pressure branch pipes 32 are connected to the second end of the negative pressure pipe 31, and the ends of the negative pressure branch pipes 32 are evenly distributed in the sticking main body 1. As a result, negative pressure is formed at multiple positions of the second end on the sticking main body 1, which not only makes the negative pressure on the sticking main body 1 and in the water sac groove 2 more uniform, but also can prevent the negative pressure pipe 31 from being blocked.

[0035] According to some embodiments of the present invention, referring to Figure 7 , a plurality of medicine delivery branch pipes 42 are connected to the second end of the medicine delivery pipe 41. The ends of the negative pressure branch pipes 32 are connected to the water sac groove 2, and the ends of the negative pressure branch pipes 32 surround the edge of the water sac groove 2. Medicine can be delivered to the wound more evenly.

[0036] According to some embodiments of the present invention, the wound repair promoting device further includes an ultrasonic device. The medicine delivery device 4 is used to deliver medicine liquid into the water sac groove 2, and microbubbles are formed in the water sac groove 2. The ultrasonic device is used to burst the microbubbles. When administering medicine, due to physical properties such as the surface tension of the medicine liquid, the medicine liquid forms a relatively stable microbubble, which will affect the absorption of the medicine liquid by the wound. In order to promote the absorption of the medicine liquid by the wound, an ultrasonic device is provided to burst the microbubbles, thereby promoting the absorption of the medicine liquid by the wound.

[0037] According to some embodiments of the present invention, the wound repair promoting device further includes a connection buckle, which is used to stick on the skin surface, and the ultrasonic device is detachably connected to the connection buckle. The connection buckle can be directly stuck on the skin, and the connection buckle can also be indirectly stuck on the skin by being fixed on the sealing film 5. When the ultrasonic device needs to work, the ultrasonic device can be fixed through the connection buckle. When the ultrasonic device does not need to work, the ultrasonic device can be directly detached from the connection buckle.

[0038] According to some embodiments of the present invention, the distance between the edge of the water sac groove 2 and the edge of the sticking main body 1 is not less than 5 mm. Thereby, the negative pressure environment in the water sac groove 2 can be better guaranteed, and at the same time, negative pressure can be applied to the skin within a relatively large area range.

[0039] In the description of the present invention, the description with reference to the terms "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
