Triggering part for unlocking and a body frame plate with an unlocking function

Abstract

The invention relates to a triggering part for unlocking and a body frame plate with an unlocking function, wherein, the triggering part is used for triggering the unlocking by adopting a foot or legof a patient; The body frame plate comprises the triggering part; The triggering part and the body frame plate provided by the invention, The invention has the advantages of reasonable structure and low manufacturing cost, and is suitable for patients of different heights, so that the radiotherapy patient lying flat and fixed on the body frame plate can trigger and unlock by his own foot or leg, not only effectively avoiding the drawbacks in the prior art, but also enabling the patient to trigger and complete the unlock more conveniently, more easily and more efficiently.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a trigger part for unlocking and a body frame plate with an unlocking function. Background technique [0002] Radiation therapy, referred to as radiotherapy, is currently one of the main means of treating malignant tumors. About 2 / 3 of the patients with malignant tumors need to receive radiation therapy. The current domestic radiation therapy has entered the stage of precise treatment, and precise radiotherapy is based on radiotherapy positioning. The image generated by CT scan is completed; radiotherapy positioning CT is to collect images of the patient's body in a unified coordinate system. The doctor outlines the tumor target area based on this image, and then the physicist designs the radiotherapy plan. After the radiotherapy plan is verified and passed Radiation therapy can then be performed; in radiation therapy, keeping the patient in a fixed position is the key ...

Problems solved by technology

[0004] In hospitals, in order to better distinguish the tumor target area from the surrounding tissue, it is usually necessary to use iodine-containing CT contrast agent (usually called contrast agent, which needs to be swallowed by the patient before scanning) for positioning-enhanced scanning, so that Delineate the target area more accurately; the common side effect of iodine-containing contrast agent is gastrointestinal reaction, and patients often have symptoms of nausea and vomiting; when the patient is not fixed with a thermoplastic film, the patient vomits You can vomit freely, and the possibility of suffocation is relatively small; however, in the case of thermoplastic film fixation, the patient's entire head, neck, and chest are usually fixed on the body frame by thermoplastic film, and the patient cannot In this case, if the patient vomits and the vomit cannot be removed, suffocation, aspiration pneumonia, etc., or even death will easily occur, which poses a great safety hazard

[0005] The body frame boards with unlocking function disclosed in the prior art can usually be unlocked on one side or both sides in an emergency. However, these body frame boards usually require the patient to trigger the unlocking by hand. On the one hand, the trigger method is single , which is not conducive to the diversification of body frame boards; on the other hand, for patients who lie flat and fixed on the body frame board, the freedom of movement of the patient's hands is limited (constrained), and it is not convenient to trigger the unlocking when lying flat
