Abstract
The utility model discloses a medical linear accelerator anticollision apparatus, including a fixed frame, a rotation frame, a frame rotation control system, a distance inductor, a controller and an alarm device. The distance inductor is arranged on the rotation frame; the output terminal of the controller is connected with the input terminal of the distance inductor; the output terminal of the distance inductor is connected with the input terminal of the alarm device; and the output terminal of the alarm device is connected with the input terminal of the frame rotation control system. In the medical linear accelerator anticollision apparatus provided in the utility model, the distance inductor is used, a physical bump between the frame and the apparatus is prevented, unnecessary loss is minimized, and simultaneously, damage caused by a bump to a patient is prevented, in addition, the induction area of the distance inductor is larger than the contact area of a mechanical type bump switch, thereby not only is installation convenient, but also practical usage is more convenient, the usage scope is wider, and the anticollision effect is better.
Description
Technical field
This utility model relates to a kind of linear accelerator collision prevention device, belongs to accelerator auxiliary device technical field.
Background technology
Clinac is to be used on a kind of biomedicine tumor is carried out radiocurable particle accelerator.Clinac in use carries out accurate target localization through the rotation of frame and collimator, the rotation and the up-down of therapeutic bed.And in the frame rotary course, bumping owing to human negligence causes frame and the patient on therapeutic bed or the therapeutic bed in the rotary course sometimes, thereby the damaging of generation equipment or patient.For preventing the generation of this type of unnecessary incident; Existing way is: several mechanical type impact switches are installed in the both sides at rotary frame, when collision takes place, can cut off the power supply of frame rotation motor owing to triggering; Give the alarm and remind the staff, thereby stop the generation of collision accident.Though this class mechanical type collision prevention device can alleviate the loss that collision brings to a certain extent; But this class mechanical type impact switch must just can be cut off the electricity supply when collision takes place and reported to the police; Then not early warning to some extent before physical impacts takes place; Therefore, even this class mechanical type collision prevention device has been installed on linear accelerator, still possibly exist the equipment or the personnel of taking place to damage owing to inertia.In addition, being limited in scope of mechanical collision switch setting, the protection area that plays is limited, still exists in actual use to use inconvenience, range limited deficiency.
The utility model content
The purpose of this utility model is: a kind of clinac collision prevention device that can prevent effectively that frame and equipment and patient from bumping possible is provided, thereby can effectively solves the problem that exists in the above-mentioned prior art.
The purpose of this utility model is to realize through following technical proposals: disclose a kind of clinac collision prevention device; Comprise fixed frame, rotary frame, frame Rotable Control System, distance-sensor, controller and alarm device, said distance-sensor is located on the rotary frame; The outfan of controller links to each other with the input of distance-sensor, and the outfan of distance-sensor links to each other with the input of alarm device, and the outfan of alarm device links to each other with the input of frame Rotable Control System.
As a kind of optimal way, wherein: said controller is located at the inside of rotary frame.
As a kind of optimal way, wherein: said distance-sensor is located at rotary frame front end both sides.
As optimal way further, said distance-sensor is four at the one-sided of rotary frame.
The effect of each part is following in this utility model: fixed frame and rotary frame and frame Rotable Control System are the parts of linear accelerator own; The effect of distance-sensor is the distance between induction rotary frame and the barriers such as equipment or patient; The effect of controller is the command range induction apparatus; The effect of alarm device is when the distance of rotary frame and barrier reaches the setting alarming value; Alarm device provides alarm signal; When the distance of rotary frame and barrier is little when setting ultimate value, cut off rotary frame drive motors power supply, to guarantee equipment and personnel's safety.
Compared with prior art; The beneficial effect of this utility model: this utility model clinac collision prevention device has used distance-sensor; Can prevent the collision physically of frame and equipment, reduce unnecessary loss, can also avoid the injury that brings with patient's collision simultaneously; In addition, therefore not only easy for installation because the induction area of its distance-sensor is big than the contact area of mechanical type impact switch, and also actual use is convenient, the scope of application is wider, the anticollision effect is better.
