Description

[Detailed description of the invention] This invention relates to a clip lead for radiological imaging and non-obstructive bioinstrumentation.

Since conventional clip leads for bioinstrumentation are made of metal conductors, they have the drawback of interfering with images when an electrocardiogram is input during radiation use.

The purpose of this invention is to eliminate the above-mentioned conventional drawbacks and provide a clip lead for bioinstrumentation that does not cause any interference with radiographic imaging.

In order to satisfy the above object, this invention is constructed as follows.

That is, in this invention, the main body 2 of the clip, which has a bendable fulcrum part 1 in the middle thereof, is made of a semi-hard insulator, and the left and right holding parts 3, 3' are made of a non-metallic conductive material that does not interfere with radiation imaging. The formed clamping pieces 4, 4' are buried so that a part of each is exposed and facing each other, and a radiographic image inserted into the operating rod parts 5, 5' of the clip main body 2 is inserted into the clamping pieces 4, 4'. Connect the core wire 6' of the non-faulty non-metallic conductive wire 6, and
And the end of the non-metallic conductive wire 6 is connected to the operating rod part 5,
5′ is covered with a soft insulating member 7 connected to both ends,
Furthermore, the clip lead for radiation imaging non-obstructive bioinstrument is constructed by compressing a spring 8 made of synthetic resin such as nylon and acting outward between the operating rod parts 5 and 5'.
In the illustrated embodiment, the spring 8 is formed into an annular shape, and a locking protrusion 10 is provided in which through holes 9, 9' are bored on the opposing circumferential surface of the spring 8 and protrude inside the operating rod parts 5, 5'. ，
10'. Reference numeral 11 indicates a conductive non-metallic adhesive that connects both the left and right holding pieces 4, 4' and the core wire 6', and 12 indicates a measurement position mark display section.

As mentioned above, in this device, all the members constituting the clip lead are made of materials that do not cause any damage to radiographic images, so even if an electrocardiogram is input during radiation use, there will be no damage to the images as in the past. There is no risk of it happening. Therefore, it can be used for a wide range of biological measurements, increasing its practical value as a clip lead for biological measurements.
