Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a medical equipment connecting wire with good shielding effect. Background Art

[0002] Medical device cables (also known as medical wiring harnesses) are a type of electrical wiring harness used in medical devices and instruments. They play a vital role in modern medical equipment, providing stable connections between various medical devices and instruments, ensuring their proper function and precise treatment.

[0003] As the variety of surgical instruments increases, the mutual interference between multiple instruments and devices has led to increasing requirements for signal shielding in connecting cables. Existing connecting cables often use an embedded shielding layer for shielding, but single-layer shielding is ineffective. Therefore, those skilled in the art have provided a medical device connecting cable with excellent shielding effectiveness to address the issues raised in the above background technology.

The insulating layer material is polyimide material. Shielding layer one is installed on the outer surface of the insulating layer. The shielding layer one material is aluminum foil. A flame retardant layer is installed on the outer surface of the shielding layer one. The flame retardant layer adopts halogen-free low-smoke flame retardant polyolefin material. Shielding layer two is woven by a mixture of copper wire and aluminum wire. A filling layer is arranged inside the second shielding layer, and the filling layer is arranged between several flame retardant layers. The filling layer material is polyvinyl chloride particles. A fire-resistant layer is installed on the outer surface of the second shielding layer. The fire-resistant layer is a quartz fiber composite material. A wear-resistant layer is installed on the outer surface of the fire-resistant layer. The wear-resistant layer material is polyurethane or chlorinated polyethylene. A shielding coating layer is installed on the outer surface of the wear-resistant layer. The shielding coating layer uses a film-forming resin as a matrix material, and then conductive fillers, diluents and additives are added.

[0005] Preferably, the conductive filler is silver powder, copper powder, nickel powder or graphene.

[0006] Preferably, the diluent is methyl cellosolve or pine oil.

[0007] Preferably, the additive is a dispersant or a reinforcing agent.

[0008] Preferably, the braiding density of the copper wires and the aluminum wires is greater than 80%.

[0009] The technical effects and advantages of this utility model are:

[0010] The utility model achieves a good shielding effect for the connecting wire through the shielding layer 1, the shielding layer 2 and the shielding coating layer. At the same time, the benzene ring and the imide group in the polyimide material of the insulating layer can absorb electromagnetic waves, thereby enhancing the electromagnetic shielding effect, so that the connecting wire has a good shielding effect.
