Protective cover for CT inspection

technical field

The invention relates to a protective cover, which belongs to the structure improvement of the CT scanning protective cover, more precisely, it is a protective cover for CT inspection

Background technique

In order to facilitate the inspection of multiple parts of the patient's body, the existing protective cover for CT inspection generally adopts a sliding multi-segment structural design, and the sliding multi-segment design easily exposes the patient's body to radiation when performing local CT scanning. The lower area is larger, resulting in more radiation damage to the patient.

For example, the Chinese patent (authorized notification number CN202537528U) discloses a "CT scanning bed telescopic protective cover", which includes at least two layers of pull-up covers, and each layer of pull-up covers has the same structure except that the length and width are different. Among the adjacent two-layer pull-out hoods, the length and width of the upper-layer pull-out hoods are larger than those of the lower layer; the telescopic connection control is realized through stoppers between adjacent pull-out hoods, wherein, in each layer of pull-out hoods Outer stoppers are evenly arranged on the upper part of the straight-side outer sidewall; except for the lowermost layer of the pull-out cover, inner upper and lower stoppers are evenly arranged on both ends of the straight-side inner sidewall of each layer of pull-up cover; and the outer The stopper is set at the position where the outer side wall of the pull-up hood is one height away from the upper edge of the pull-up hood, and the inner upper and lower stoppers are arranged on the inner side wall of the pull-up hood and the upper and lower sides of the pull-up hood The position of the edge alignment. The utility model has the advantages of simple structure and convenient assembly, and the gap between layers can be adjusted, thereby avoiding the interference phenomenon. .
