Problems solved by technology

Therefore, in view of the fact that bacterial drug resistance is getting stronger and the existing antibiotics are not effective for chronic infections, relying on the body's own internal defense mechanism, the method of using gallium to sterilize bacteria is a brand-new method for treating bacterial infections. Useful ways

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] figure 1 A schematic structural diagram of a fixing bandage based on a liquid metal flexible composite material provided by the present invention is also an embodiment of the present invention.

[0023] When the composite flexible material is only used for general fixation and does not require drug application or compression to stop bleeding, only the thin pipe network 3 filled with liquid metal 2 can be used. By heating, the thin pipe network 3 filled with liquid metal is heated to above the phase transition temperature. At this time, since the liquid metal 2 filled in the thin pipe network is in liquid state, the entire thin pipe network is flexible and can be bent arbitrarily. On the part of the human body that needs to be fixed, the liquid metal filled becomes solid after cooling, and after hardening, the shape of the entire thin pi...

Abstract

The invention relates to a fixing bandage based on a liquid metal flexible composite material. The fixing bandage comprises liquid metal, a thin pipe network containing the liquid metal, and a medical fiber material for being compounded with the thin pipe network, wherein the flexible composite material can be made into different shapes according to demands; as a novel bandage, the fixing bandage can be used for binding and fixing the four limbs, the trunk, the head and the like of the human body; compared with the traditional fixing methods adopting gypsum, splints and the like, the fixing bandage has the advantages of simplicity in operation, portability and comfort in use, good breathability, reduction in infection, wide application range, recycling property and the like; the flexible composite material is stable in property and high in reliability, and the deficiency and defects of the traditional medical material are made up to a certain extent.

Description

technical field [0001] The invention relates to the technical field of bandages, in particular to a deformable composite flexible material containing liquid metal that can be phase-changed at normal temperature; the composite material can be converted between flexibility and rigidity through phase change at normal temperature, and this can Conversion materials can be used to design bandages for medical immobilization. Background technique [0002] In medical practice, the bandaging and fixation of the wound site is a very important task. In many surgical wounds, bandages need to be used to fix the damaged site, and at the same time, it can also play the role of compressing and hemostasis, and applying drugs. When a patient suffers from a fracture, a bone fracture, etc., in addition to the bandage, a splint or a plaster should be used to fix the injured limb of the patient to avoid accidental movement that may cause dislocation or fracture of the bone, or cause additional tra...
