Description

Limb constraint device for radiotherapy of tumor patient Technical Field The invention relates to the technical field of limb restraint of tumor patients, in particular to a limb restraint device for radiotherapy of tumor patients. Background Tumor radiotherapy is a local treatment method for treating tumors by using radiation, and takes an important role in tumor treatment, about 70% of cancer patients need to receive radiotherapy in the treatment process, about 40% of cancers can be radically treated by radiotherapy, and position fixing is a key step of implementing radiotherapy, and throughout the whole radiotherapy process, the patients need to maintain a specific position during radiotherapy so as to ensure that the radiation can accurately irradiate the tumor part and simultaneously reduce the damage to surrounding normal tissues as much as possible; In the limb constraint device for radiotherapy of the existing tumor patient, the traditional constraint device lacks an effective self-adaptive adjusting function, on one hand, when the patient breathes normally in the radiotherapy process and body fluctuation occurs, the constraint belt can not be correspondingly adjusted according to body movement, and the situation of overstretching or slackening is very easy to occur, so that obvious constraint feeling and oppression feeling can be brought to the body of the patient, the comfort degree of the patient in the radiotherapy process is very poor, body torsion can be generated due to discomfort of the patient, the radiotherapy is further influenced, on the other hand, the body position of the patient is difficult to keep relatively stable in the respiration process due to the fact that the self-adaptive adjustment is not carried out, deviation is very easy to occur at a radiotherapy part, so that the radiotherapy can not accurately act on a target area, the treatment effect is greatly reduced, in addition, in order to cope with the constraint problem brought by the patient respiration, medical staff needs to frequently and manually adjust the constraint belt, not only unnecessary workload is increased, but also medical staff is difficult to concentrate on the radiotherapy operation per se, and smoothness and accuracy of the radiotherapy flow are seriously influenced by interference of external factors. The invention provides a limb restraint device for radiotherapy of tumor patients, which solves the problems. Disclosure of Invention (One) solving the technical problems Aiming at the defects of the prior art, the invention provides a limb restraint device for radiotherapy of a tumor patient, which can effectively solve the problems in the prior art. (II) technical scheme In order to achieve the above object, the present invention can be achieved by the following technical solutions: A be used for tumour patient radiotherapy to use limbs constraint device, including the constraint bed, a plurality of spout has been seted up to constraint bed up end symmetry, equal sliding connection has the movable block in the spout, the homonymy the movable block up end is all seted up flutedly, still includes bandage self-adaptation regulation early warning mechanism and the spacing adjustment mechanism of bandage, bandage self-adaptation regulation early warning mechanism includes the support frame, the support frame all is located the movable block top of seting up flutedly, the equal fixedly connected with curb plate in movable block both sides, the support frame upper end all runs through and rotates and be connected with the pivot, the equal fixedly connected with slider of terminal surface under the support frame, the equal sliding connection of slider is in the recess, the equal fixedly connected with spring in slider both sides, the equal fixedly connected with of slider one end is kept away from to the spring on the recess inside wall, bandage self-adaptation regulation early warning mechanism is used for improving patient's comfort level, the spacing adjustment mechanism of bandage is used for being convenient for medical staff to tie up the patient. As a further scheme of the invention, the upper end faces of the side plates are symmetrically and fixedly connected with support plates, support columns are fixedly connected between the support plates on the same side, the outer surfaces of the support columns are respectively and slidably connected with a connecting block, and the connecting blocks are respectively and fixedly connected to the side walls of the support frames. As a further scheme of the invention, the lower end face of the connecting block is fixedly connected with a pressing rod, buttons are arranged on two sides of the pressing rod, the buttons are fixedly connected to the upper end face of the side plate, alarms are electrically connected between the buttons on the same side, and the alarms are fixedly connected to the side wall of the supporting plate. According to the invention, the handle
