In recent years, with people's increasing attention to health, the demand for large-scale high-performance diagnostic and therapeutic equipment is increasing. High-speed development of computers and other high-tech technologies have made radiological diagnostic and therapeutic equipment toward smaller radiation doses and more imaging. Clear digital development.
Traditional medical bedboards are mostly made of wood and plastic. These two materials are not only heavy in weight, but also poor in wave permeability for rays, which can produce a large tendency to refraction. In order to achieve the purpose of diagnosis and treatment, it is necessary to increase the voltage, the radiation energy increases, causing harmful side effects to the patient, and the contrast is not clear enough, and energy is also wasted.
After countless studies by scientists, carbon fiber composite materials can not only have high permeability to X-rays, but also have certain parts with sufficient rigidity and strength, making them one of the best materials for manufacturing radiological medical equipment.
The carbon fiber composite material is mainly composed of carbon fiber and epoxy resin. The former is a reinforcing material, which mainly plays a bearing role, and the latter is a matrix material, which is used to support carbon fiber and transfer external loads to it.
Carbon fiber composite materials have outstanding advantages in the medical field
1. Good mechanical properties
Carbon fiber composite materials have higher strength than metals such as steel, and are lighter in weight and higher in specific modulus. In medical equipment, it can be used to make high-strength and light-quality accessories.
2. Has excellent corrosion resistance
Medical CT bed board will inevitably be contaminated with drugs, blood stains, sweat stains, vomit, etc., thus affecting the service life of the bed board, carbon fiber medical CT board can resist acid, alkali, salt and other corrosion, easy to clean, extend the service life.
3. Excellent X-ray transmission performance
The elemental composition of the resin is C, H, O, and the elemental composition of the carbon fiber is C. The X-ray mass absorption coefficient is very small, far lower than that of ordinary materials, and the X-ray transmission performance is much better than traditional medical materials such as wood and aluminum plates. The carbon fiber composite material allows the rays to be irradiated on the bed board at any angle without refraction, thereby causing less side effects on the patient and saving energy.
4. Good anti-fatigue performance
The large amount of patient diagnosis and treatment requires high fatigue performance of medical CT bed panels. During the use of the carbon fiber medical CT bed, even if a small amount of fiber breaks, its load will be quickly redistributed to the undamaged fiber, so that the entire member will not lose its load bearing capacity in a short time, thus showing that the carbon fiber structure is good Damage safety performance.
It can be seen from the above that the carbon fiber composite medical CT board has great advantages over other materials. As the cost of materials decreases and the technology matures, it is believed that the application of carbon fiber composite materials will become more and more extensive.
