Embodiment 1

[0030] The preparation material of embodiment 1 non-magnetic medical device

[0031] Epoxy resin is selected as the thermosetting resin, and the carbon fiber material is a commercially available fiber cloth. The fiber material includes fiber cloth in which carbon fiber tows are staggered, and also includes fiber cloth in which carbon fiber tows are arranged in parallel. The proportion by weight is 18:82, the carbon fiber cloth has 4 layers, the surface layer is a fiber cloth with carbon fiber tows arranged in a staggered manner, and the interlayer in the middle is a fiber cloth with carbon fiber tows arranged in parallel.

[0032] When in use, epoxy resin is coated on the surface of the carbon fiber cloth, and then the carbon fiber cloth is stacked together for compression molding, so that the non-magnetic carbon fiber composite material forms the device of the required equipment.

[0033] It should be noted that the technical purpose of the present invention can be realized i...

Abstract

The invention discloses an application method for applying carbon fiber to a non-magnetic medical device preparation material and a preparation method of a non-magnetic medical device and relates to the field of medical device preparation materials. The non-magnetic medical device preparation material comprises thermosetting resin and a carbon fiber material, wherein a bonding agent serves as thethermosetting resin; the weight part ratio of the thermosetting resin to the carbon fiber is (5-28):(72-95), preferentially, (9-24):(76-91), and further preferentially, (18-20):(80-82). By suing the thermosetting resin, the roughness of the fiber surface is improved, the surface area of the surface of the carbon fiber is increased, the interface bonding performance between the carbon fiber and a resin base body is improved, and the composite is excellent in overall performance. A non-magnetic medical transfer bed manufactured from the non-magnetic carbon fiber composite only has the weight of16 kg, has the bearing capacity up to 150 kg and the tensile strength greater than 3500 MPa or above, has good corrosion resistance, has no magnetism and can be completely applied to MR examination rooms.

Description

technical field [0001] The invention relates to the field of medical device preparation materials, in particular to the use of carbon fibers for non-magnetic medical devices. Background technique [0002] Nuclear magnetic equipment has strong magnetism, and the magnetism will not disappear under normal working and non-working conditions. When ferromagnetic objects approach, it will cause great harm. For example, when ferromagnetic objects, such as ordinary transfer beds, wheelchairs, Oxygen tanks, etc. are brought into the high magnetic field of nuclear magnetic equipment, and will fly to the machine like shells and bullets, causing "missile effect" or projectile damage. [0003] Since most of the existing medical devices are made of metal materials, such as medical transfer beds, they have many functions and complex structures, and the connecting mechanisms are all made of metal materials, so they are not suitable for nuclear magnetic chambers. [0004] Carbon fiber (CF fo...
