Description

Multifunctional LED pulse light yarn cloth device for promoting wound healing

The wound healing process is divided into three stages: inflammation, proliferation and maturity. In the inflammatory phase, immune cells such as T cells and B cells consume oxygen to swallow and destroy the invading bacteria, while fibroblasts begin to proliferate and move to the wound. After entering the proliferative phase, the tissues appear temporarily due to the previous large oxygen consumption. In hypoxia, fibroblasts attract adjacent blood vessels to form new blood vessels to transport oxygen, and secrete more collagen to fill the wound. Epithelial cells also begin to deform and move to the granulation tissue to cover the wound, while mitochondria supply the cells needed for cell operation. The energy, these processes continue to mature, the wound shrinks and heals, each stage needs enough oxygen to assist.

Oxygen is so important for wound healing, but after the human body is injured, the blood vessels in the wound tissue rupture and the red blood cells transport oxygen pathways are blocked. We began to think about the feasibility of using oxygen for treatment, and tried various ways to increase the oxygen concentration of the wound tissue, such as letting the disease. Patients should breathe pure oxygen in a special pressure chamber to increase the oxygen content of the blood and increase the oxygen concentration of the wound tissue. However, this method is costly, and systemic oxygen supply may cause excessive oxygen concentration in other parts of the body, resulting in pneumothorax Or cerebrovascular embolism and other side effects.

The other method is to increase the oxygen concentration in the wound tissue to avoid the risk of hyperbaric oxygen treatment, reduce medical costs and improve mobility; but oxygen is difficult to dissolve in liquids such as water and blood, and cannot reach the depths of the wound, which is effective for deeper wounds. limited. In order to increase the oxygen concentration locally and make it penetrate deep into the wound tissue, the problem of water solubility must be overcome. The application of carbon dioxide has become an effective way to solve this problem.

In 1904, the Danish physiologist Christian. Proposed by Christian Bohr The "Bohr effect" increases the concentration of carbon dioxide to make the blood pH more acidic, and promotes the release of oxygen from the heme in the red blood cells. Carbon dioxide therapy uses the "Bohr effect" to promote the presence of heme in muscle tissues and peripheral tissues. Release more oxygen, activate cells and promote blood circulation, thereby promoting wound healing.

On the other hand, the speed of healing of human wounds depends on whether the current medical treatment is appropriate or not, the follow-up treatment is also an important factor. The recovery of severe wounds usually takes several weeks. Many medical experts and scientists are doing their best to develop the most appropriate wound healing therapies. Studies have found that baking soda tablets can be decomposed to produce carbon dioxide after moderate heating, forming a weak acid environment in the wound area, thereby increasing blood circulation and oxygen supply in the wound area, achieving the purpose of promoting wound healing; and using red light to treat skin ulcers , Blue light irradiation can relieve itching and sterilization. Irradiate the skin wounds with specific red and blue light every day. About 2-3 weeks, it can improve skin wounds and ulcers. However, there is currently no soft product that has the above-mentioned effect and can be light and thin. Cover the injured area.

Therefore, we have developed a multifunctional wound healing device that can not only transmit the narrow-band red light and blue light LED pulse light yarn cloth, but also apply electric heating to the baking soda tablets. This creation includes a smart wearable wound healing device and a mobile device APP software; the smart wearable wound healing device is divided into four layers, the first layer is the 3D printed hole-shaped TPU fixing bracket closest to the human wound and skin, and the outside The first layer is a removable hole-shaped baking soda sheet, followed by a net-shaped soft electric heating sheet, the outermost layer is an LED pulse light yarn cloth, and the net-shaped soft electric heating sheet and LED pulse light yarn cloth are equipped with temperature sensors The mobile device APP software can effectively guide the smart wearable wound healing device through Bluetooth wireless transmission and control, and can be transferred to the cloud to be controlled by the remote control management center.

Wound healing therapies are changing with each passing day of science and technology. From the development of new materials to molecular biotechnology, and even the creation of suitable physical and chemical environments, many emerging therapies are gradually maturing, but no matter what method, wound dressing is undoubtedly the most basic medical treatment. Material is also one of the most critical factors to promote wound healing. At present, there are many common materials covering wounds, such as gauze, transparent membrane waterproof dressing, debridement gel, foam dressing, algin, growth factor and antibacterial dressing, etc. Each has its own advantages and disadvantages, but gauze has its own advantages and disadvantages. It is still the most widely used and the most basic medical material. However, its disadvantage is that it must be replaced frequently, and it is easy to stick. When replacing it, it is easy to cause new tissue damage and increase the patient's pain. In addition, gauze can also easily cause the wound to dry out and reduce collagen. Synthesis. On the other hand, traditional wound care methods include wound infection control, provision of nutritional supplements, ventilation of the wound area, debridement, skin transplantation and proper massage. At the same time, ultrasound, electrical stimulation, laser irradiation, etc. are used to assist wound healing. Treatment methods, but most of these therapies are time-consuming, labor-intensive and ineffective. Therefore, the development of one can promote wounds New healing products have always been urgently needed by the medical care industry.

In view of this, the multifunctional LED pulsed light yarn cloth device created to promote wound healing uses red and blue LED pulse light that is beneficial to the human body and skin, and uses a small amount of heating to decompose the baking soda tablets.
