CT collision protection device and CT collision protection method thereof

Abstract

The invention discloses a CT collision protection device and a CT collision protection method thereof. The CT collision protection device comprises a collision distance sensor, an infrared induction sensor, a misoperation processing unit and a control feedback unit, wherein the collision distance sensor is vertically arranged on the end face, close to a CT rack housing, of a CT scanning bed body;when it is detected that the CT rack housing enters the safe distance of the CT scanning bed board, warning information is output; the infrared induction sensor is arranged at the upper end of the CTrack housing and outputs warning information after detecting that an examined patient leaves the safe area; the misoperation processing unit is used for outputting a collision signal when one of the CT scanning bed board and the CT rack housing moves; the control feedback unit is connected with a CT motion module; and the collision distance sensor, the infrared induction sensor and the misoperation processing unit are all connected with the control feedback unit, so that the CT motion module is controlled to stop moving when the warning information and the collision signal are received at thesame time, and collision between the CT scanning bed and the CT rack housing is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, relates to a CT collision protection device. In addition, the present invention also relates to a CT collision protection method applied to the above-mentioned CT collision protection device. Background technique [0002] CT is widely used in the field of clinical medicine. During the scanning process, the CT scanning table can move forward and backward longitudinally and vertically, and the cover of the CT frame can tilt forward and backward. Because the motion relationship between the two is relatively complicated, the collision protection belt for CT Come to great challenge. [0003] Most of the collision protection in the prior art is to prevent the patient under examination from being squeezed, such as setting an infrared sensor to detect whether the patient under examination is squeezed; or using resistive materials and capacitive materials to make a fixe...

AI Technical Summary

Problems solved by technology

The former cannot solve the problem of collision between the CT frame cover and the lower end of the CT scanning bed when it is tilted, and the infrared sensor has interference with the doctor's positioning; while the latter can solve the problem of collision between the CT frame cover and the lower end of the CT scanning bed when it is tilted, However, the manufacturing cost of the resistive / capacitive CT scanning bed fixed cover and the CT frame cover is extremely high, often costing millions

[0004] In addition, there is also a collision protection method that uses software algorithms to detect the distance between the CT scanning table and the CT frame cover, but this method will introduce software calculation risks, and there is still a risk of collisions
