Carbon fiber composite materials are light in weight and excellent in mechanical properties, which makes it widely used in the field of medical devices with strict manufacturing requirements. At present, with the maturity of carbon fiber related technologies, carbon fiber composite materials are accepted by more medical device manufacturers.
Carbon fiber composite materials have various applications in medical devices, and new applications are constantly being developed. Today, I will list several common carbon fiber medical device products to see the application of carbon fiber composite materials in medical devices.
Carbon fiber prosthesis
The link transfer part of the prosthesis and human body is called the receiving cavity, which mainly wraps the residual limb and transfers power. The load-bearing requirements of this part are high and not too heavy. Carbon fiber material can also be used as the material for this part. The part for accommodating the residual limbs can be made of polyethylene plate, and the support body can be made of carbon fiber to make the frame structure, so as to realize easy support and transmit power.
The joint of the human ankle and foot plays a key role in the balance and support of the body. The ankle joint made of carbon fiber can realize the jumping function of the human body. In addition, the joint part of the ankle and calf prosthesis can also be realized with carbon fiber. The overall production is very beautiful.
Carbon fiber medical bed board
It can be said that there are many applications of carbon fiber in medical bed boards. During CT diagnosis and radiotherapy, it is very important that the dose of radiation reaches the patient's lesion accurately. Carbon fiber composite materials are widely used in X-ray digital machines, PET machines, CT machines, MR machines, SPECT machines; radiotherapy has rapidly moved from conventional radiotherapy to IMRT (Intensity Modulation Conformal Radiation Therapy), IGRT (Image Guided Radiation Therapy), The development of precision radiotherapy technologies such as IMAT (rotation intensity modulated radiation therapy), these new radiotherapy technologies have greatly improved the dose accuracy, and also put forward higher requirements on the bed surface of the treatment machine.
The bed board made of carbon fiber composite material has a smooth and smooth surface and high X-ray transmittance; it allows rays to be irradiated on the bed board at any oblique angle without causing large deviations in refraction and projected rays, and uses less material , To achieve the designed structural strength and rigidity, reduce weight and high tensile strength.
Carbon fiber wheelchair
The density of carbon fiber is only 1.7g / cm3, and the accessories of the same specification are more than half lighter than those of aluminum alloy, but the strength is much greater. In addition, carbon fiber also has strong corrosion resistance, and a large proportion of wheelchair patients face Incontinence and frequent contact with injection liquids, etc. In this case, the accessories of carbon fiber composite materials show durability that is unmatched by ordinary metal materials.
At present, carbon fiber composite materials are mainly used in accessories such as armrests, armrests, footrests, legrests, backrests, skirt boards and frame tubes. Most of these accessories can be adjusted in height. Carbon fiber composite materials are easy to assemble with wheelchairs through mechanical connections. The most important thing is that after using these carbon fiber composite materials for these accessories, the overall weight of the wheelchair has been significantly reduced, and as a part of high frequency of use, it has become more durable.
Taking the electric wheelchair accessories as an example, the weight of the electric wheelchair using carbon fiber composite materials is only 14kg, which is about 33% lighter than the 21kg of the traditional aluminum alloy electric wheelchair. In terms of weight bearing, the traditional aluminum alloy wheelchair weighs 100kg and uses The carbon fiber material electric wheelchair can bear 200kg, suitable for more people; in terms of endurance that is most concerned, thanks to the lightweight characteristics of carbon fiber, this carbon fiber electric wheelchair can travel 40km on a single charge, and the maximum speed can reach 8km / h. The driving distance of the traditional electric wheelchair is only 20km, and the driving distance is increased by 50%. Compared with the traditional wheelchair accessory materials, the electric wheelchair using carbon fiber materials has been greatly improved in all aspects.
With the advancement of science and technology, the application of carbon fiber has become diversified. Due to the excellent performance of carbon fiber composite materials, it is inevitable to become the mainstream in medical device materials. Compound material companies also actively optimize their own technologies in accordance with the trend and provide more high-quality carbon fiber medical device products for everyone.
