Description
Technical Field
The invention relates to a phototherapy irradiation device, in particular to a phototherapy irradiation device for promoting different types of wounds to heal, and belongs to the technical field of medical instruments.
Background
Biological wound healing is a complex process including an acute inflammation phase, a cell proliferation phase and a repair phase 3 phases, each of which affect each other. The type of wound (e.g., surgical wound, contaminated wound, refractory wound), the extent of injury and the ability of tissue regeneration determine the manner in which the wound is repaired, the healing time and the size of the scar. The therapeutic principle should be timely sterilization to prevent re-injury and promote tissue regeneration.
According to research, factors influencing wound healing are divided into systemic factors and local factors, and the two factors have great influence on wound regeneration and repair.
Systemic factors: systemic factors include age, nutrition and disease. In age, adolescents have strong tissue regeneration capacity and rapid wound healing speed. The old people have weak tissue regeneration capability and slow healing, and have great relation with the aging of blood vessels and the reduction of blood supply of the old people. Nutritionally, there is a delay in granulation tissue and wound healing when protein, and especially sulfur-containing amino acids, are deficient. In the aspect of diseases, diabetes and other diseases cause a series of influences such as blood sugar rise and blood flow reduction, and wounds are difficult to heal.
Local factors: local factors include wound infection aspects, local blood circulation aspects. In wound infection, infection presents a major obstacle to wound repair, and many suppurative bacteria produce toxins and enzymes that can cause tissue necrosis and matrix or collagen fibril lysis. This not only aggravates the local tissue damage, but also hinders healing. When a wound is infected, the exudate is so large that it can increase the tension of the local wound, often causing the healing wound or the sutured wound to split open, or causing the infection to spread and aggravate the injury. On the one hand, it ensures the oxygen and nutrients required for tissue regeneration, and on the other hand, it also plays an important role in the absorption of necrotic substances and in the control of local infections. When local blood flow is well supplied, regeneration and repair are good, and conversely, when the lower limb blood vessel has atherosclerosis or varicose veins and causes local poor blood circulation, the wound is slowly healed.
A number of wound healing techniques have not been studied to date, and for the prior art:
(1) sterilizing and bandaging: disinfecting with iodine tincture or alcohol or purple water, and rubbing from inside to outside along the wound edge without applying iodine tincture or alcohol into the wound. If foreign matters exist in the wound, the wound should be carefully treated, is large and easy to take out and can be taken out; deep and small, difficult to remove, and not reluctant to remove, so as to avoid introducing bacteria into the wound or increasing bleeding. A piece of clean cloth is attached to a hard object to press the wound. If the wound is on the limbs, the wounded part is lifted to be higher than the heart, blood can be stopped slowly, and the wound is waited to be naturally healed after the dressing is completed.
The problems that exist are that: the healing speed of the wound by the disinfection and package method mainly depends on the autoimmunity, and the wound is very slow to heal for the old and the diabetic patients without external treatment intervention.
(2) Use of the dressing:
various modern dressings have been developed based on the theory of wet healing. The dressing is divided into dressing for assisting wound treatment (including debridement dressing and anti-infection dressing) and dressing for accelerating wound repair (including moisture retention, liquid seepage management dressing, growth promotion dressing, tissue engineering skin and the like), provides a comfortable environment, protects an ulcer surface, controls seepage and the like.
The problems that exist are that: at present, the traditional dressing and the novel dressing have advantages and disadvantages, the types of the existing dressings are various, various new materials are continuously made, the functions are increasingly improved, but the purposes of the dressing are different from those of the ideal dressing in the true sense, and the dressing has a certain difference and has poor treatment effect on chronic ulcers such as diabetic ulcers, pressure sores and the like.
(3) Negative pressure wound therapy: the medical foam embedded with the drainage tube covers the whole wound surface and is connected with a negative pressure machine through a sucking disc and a pipeline to realize negative pressure wound treatment, and the medical foam is non-invasive treatment. The wound surface is in a wet environment, the local blood flow is increased, the local edema is eliminated to a certain degree, the exudation is reduced, the microenvironment is improved, the deep cavity of the wound surface is reduced, the mechanical stress is changed, the cell proliferation is promoted, the angiogenesis and the granulation tissue hyperplasia are promoted, and the purposes of reducing the size of the wound and promoting the healing of the wound are achieved.
The problems that exist are that: there is currently insufficient evidence to support the benefits of negative pressure wound therapy as an adjuvant healing measure to control bioburden.
(4) Phototherapy equipment: at present, near-infrared therapeutic instruments are adopted in phototherapy instruments for treating diabetic feet on the market, flexible therapeutic pieces are selected for the therapeutic instruments, and light sources are arranged in the therapeutic pieces to irradiate the wounds of patients. The instrument adopts a specific single-wavelength infrared ray light energy treatment system, the specific wavelength is generally 890nm +/-10 nm, the penetrating power can reach subcutaneous 5cm, the near infrared ray therapeutic apparatus is used as a simple, high-efficiency and easy-to-use rehabilitation treatment device, no wound and no side effect exist, and the autoimmune rehabilitation system is excited by improving local blood circulation of the near infrared ray therapeutic apparatus.
The problems that exist are as follows: the phototherapy instruments on the market mostly adopt single near infrared wavelength therapy, only pay attention to penetration depth, but neglect specific absorption of different biological tissues to light in the wound healing process, do not consider the absorption wavelength range of different photoreceptors, and cause that the treatment effect is unstable and not significant. Meanwhile, the spot range, the positioning, the usability and the like of the phototherapy instrument have large differences. .
