Description

High-affinity liquid dressing capable of being rapidly effective

Technical Field

The invention relates to the field of medical dressings, in particular to a high-affinity liquid dressing capable of quickly taking effect.

Background

The repair of the damaged wound surface of a body caused by mechanical, physical, chemical, biological or pathological reasons is an old problem in medicine, and the traditional way is that dressings such as gauze, cotton pads and plaster cover the wound to assist the healing of the wound. However, the traditional method has slow healing speed and is easy to infect, and especially has unsatisfactory effects on emergency hemostasis of some acute wounds and follow-up care of chronic wounds (such as superficial II degree burns and scalds, diabetic feet, ulcers and bedsores). With the development of the times, as a novel medical material, the bioactive glass has good biocompatibility, and a large number of microporous channels are arranged inside the bioactive glass, so that the bioactive glass can facilitate the transmission of nutrient components, the adhesion of proteins and peptides in extracellular matrix and the acceleration of the generation speed of a hydrous silicic acid gel layer, and further can accelerate the wound healing speed, and is widely applied as a raw material of dressing. However, in practical application, the biocompatibility of the bioactive glass raw material directly used in the existing bioactive glass dressing is not good enough, and the practical application effect of the dressing is influenced, so that the applicant invented a preparation method of bioactive glass (patent application No. ZL 201610870495.2), and by supplementing mild animal materials to the surface of the bioactive glass, the compatibility and affinity with human bodies are improved, and the anaphylaxis and rejection reaction are reduced. Good economic benefit and social benefit are obtained. However, we have further studied the action mechanism of the product in order to further improve the use effect of the product. The reason why the bioactive glass is found to achieve a good healing effect is that when the bioactive glass enters human body fluid, hydroxyapatite substances are deposited on the surface in the environment of the body fluid. The hydroxyapatite is an important raw material for forming skeleton, can be combined with organism tissue on the interface by chemical bond, has a certain solubility in vivo, can release ions harmless to the organism, can participate in vivo metabolism, has stimulation or induction effect on hyperosteogeny, can promote the repair of defective tissue, and shows bioactivity, so the wound healing effect is closely related to the mineralization speed of the hydroxyapatite, the hydroxyapatite completely mineralization time under the normal condition is about 21.5hrs, and the mineralization time is more than 1hr even if nano bioactive glass is used as the raw material. The difference in mineralization time causes slow speed of healing promotion and risks of spillage and loss of dressing or newly generated mineralized substances by blood, and functional dressings in the current market have no triple effects of imbibing, inhibiting bacteria and promoting healing, and are high in material cost and selling price, so that the actual application effect and batch popularization of the dressing are influenced.

In the above two embodiments, those manufactured by the Guangzhou Ezepine Biotechnology Ltd

VEC and

VAC plant extract bacteriostatic agent

VEC comprises cortex Cinnamomi extract, flos Caryophylli bud extract, herba Artemisiae Scopariae extract, cortex Magnolia officinalis bark extract, radix Sophorae Flavescentis extract, semen glycines extract active substance, 1, 2-hexanediol, and butanediol.

VEC comprises peony root bark extract, herba Artemisiae Scopariae extract, cortex Cinnamomi extract, flos Caryophylli bud extract, Galla chinensis extract, 1, 2-hexanediol, and butanediol. The plant extraction bacteriostatic agent can influence the membrane potential of the somatic cell and slow down the metabolism of bacteria by influencing the permeability and the function of the cell wall and the cell membrane,eventually die; on the other hand, the energy metabolism and the material synthesis of the thalli and the synthesis of nucleic acid and protein can be influenced by interfering the related synthetase system in the thalli, the replication and the transcription of genetic materials are blocked, the synthesis of protein is interfered, the growth and the reproduction of the thalli are inhibited, and the death of microorganisms is caused.

The buffer solutions in the above examples 1 and 2 are prepared by leaching based on animal affinity bioactive glass patented by the applicant, and the buffer solution prepared in this way is a semi-mineralized buffer solution, which is beneficial to increasing the mineralization speed of the wound surface. The difference between the leaching method in example 1 and the leaching method in example 2 is that the proportion of calcium ions in the final buffer solution in the leaching 2 is higher, so that the later mineralization speed is relatively faster. The reason for using the animal affinity bioactive glass is that the bioactive glass has better compatibility with human skin after being treated by the tussah protein, and can reduce the anaphylactic reaction when the whole liquid dressing is contacted with the skin.

The reason why the animal affinity bioactive glass is used as the carrier of the zeolite molecular sieve in the embodiment is that although the zeolite molecular sieve has a good hemostatic effect, the zeolite molecular sieve can generate transient local high heat to cause discomfort when contacting wound blood, and the high heat burn and discomfort can be effectively reduced after the load is modified, so that the healing effect and the survival rate are improved.

The working principle of the invention is as follows:

the process of forming the hydroxyapatite-like structure is the mineralization process of bioactive glass, and is one of the main factors for promoting the healing of skin wounds rapidly when the bioactive glass is used as a dressing, when the common bioactive glass 45S5 is used as a dressing, the surface mineralization mechanism is shown in figure 1, the mineralization time in simulated artificial body fluid is basically about 21.5hrs, the FT-IR spectrogram after mineralization is shown in figure 2, the mineralization time is also generally about 1hrs even when the nano-scale bioactive glass is used, the ion leaching ratio in the buffer is basically the same as that in the bioactive glass in the application, the 72hrs leaching IR chart is shown in figure 3, as can be seen from the comparison of the peak shapes in figures 2 and 3, the hydroxyapatite-like structure in the buffer is already appeared, and compared with the mineralization process in body fluid of the conventional bioactive glass dressing, the bioactive glass is not contacted with the body fluid, and the condition that the ion form is mainly used is called semi-mineralization, because the condition is unstable, when the hydroxyapatite-like structure in the buffer solution contacts with body fluid, hydroxyapatite-like structure with stable structure can be rapidly produced and deposited near the wound, namely the mineralization step is completed. The actual verification shows that the complete mineralization time is 10-15 minutes, the speed is far higher than that of the common mesoporous bioactive glass, and the mineralization speed is also obviously improved compared with that of the nano-organic bioactive glass. The rapid and complete mineralization has good effects on promoting acute wound healing, particularly healing wounds such as diabetic wounds, bedsores and the like, healing wounds in complex environments after cancer operations and healing wounds after infected operations, specific data are shown in tables 5-8, and the overall healing time can be obviously shortened according to the data. On the basis, the liquid absorption and hemostasis capabilities are enhanced by adopting the modified bioactive glass loaded molecular sieve, and the effect of quickly stopping bleeding of patients with acute traumatic bleeding is achieved, specific data are shown in table 9, and as can be seen from the table, the average hemostasis time of example 1 is about 26s, the shortest time is 17s, the longest time is 45s, the average hemostasis time of example 2 is about 24s, the shortest time is 15s, and the longest time is 35s, so that the hemostasis speed of example 2 is slightly higher, and the data range concentration is better.
