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 process 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 are widely used in medical devices, and new applications are constantly being developed.
Today, let’s list several common carbon fiber medical device products and look at the application of carbon fiber composite materials in medical devices.
Carbon fiber prosthesis
The link between the prosthesis and the human body is called the receiving chamber, which mainly wraps the stump and transmits force. This part of the load-bearing requirements are high, and not too heavy, carbon fiber material can also be used as a material for making this part. The part containing the stump can be made of polyethylene plate, and the support body can be made of carbon fiber frame structure to achieve easy support and transfer force.
The joint movement of the ankle and foot of the body plays a key role in the balance and support of the body. The ankle joint made of carbon fiber can realize the human body jumping function, and the connecting part of the ankle and the lower leg prosthesis can also be realized by carbon fiber.
Carbon fiber medical bed board
The application of carbon fiber in medical bed board can be said to be more. In CT diagnosis and radiation therapy, it is very important that the dose of radiation accurately reach the patient’s lesion. Carbon fiber composites are widely used in X-ray digital machine, PET machine, CT machine, MR Machine, SPECT machine; Radiotherapy has rapidly developed from conventional radiotherapy to IMRT (intensity-modulated radiotherapy), IGRT (image-guided radiotherapy), IMAT (rotary intensity-modulated radiotherapy) and other precise radiotherapy technologies. These new radiotherapy technologies have greatly improved the dose accuracy, and also put forward higher requirements for the bed surface of the therapy machine.
The bed plate made of carbon fiber composite material has smooth and smooth surface and high X-ray transmittance; And allow the ray to irradiate on the bed plate at any inclined Angle, without causing a large deviation in refraction and projection of the ray, and the use of less material, to achieve the design of structural strength, stiffness, weight reduction, high tensile strength.
Carbon fiber wheelchair
The density of carbon fiber is only 1.7g/cm3, the same specification of accessories than the aluminum alloy material is more than half, but the strength is much greater, in addition, carbon fiber also has a strong corrosion resistance, a considerable proportion of wheelchair patients face incontinence and often with the injection solution contact and other problems, in this case, Carbon fiber composite parts exhibit durability that is difficult to match with ordinary metal materials.
At present, carbon fiber composite materials are mainly used in accessories such as handrails, arm supports, foot supports, leg supports, backrest, skirt plates and frame tubes. Most of these accessories can adjust the height, and carbon fiber composite materials are easy to assemble with the wheelchair as a whole through mechanical connection. The most important thing is that after using carbon fiber composite materials, the overall weight of the wheelchair has been significantly reduced. And as a highly used component, it has become more durable.
For example, the weight of the electric wheelchair using carbon fiber composite materials is only 14kg, which is about 33% less than the 21kg of the traditional aluminum alloy electric wheelchair. In terms of load-bearing, the traditional aluminum alloy wheelchair can bear 100kg, while the electric wheelchair using carbon fiber material can bear 200kg, which is suitable for more people; In terms of endurance, thanks to the lightweight characteristics of carbon fiber, the carbon fiber electric wheelchair can travel 40km on a single charge, and the speed can reach up to 8km/h, while the traditional electric wheelchair has a driving distance of only 20km, which is 50% higher than the traditional wheelchair accessories. The use of carbon fiber electric wheelchair has been greatly improved in all aspects.
